Alsharif NOUVEAU BUREAU DE LA SOCIETE ALGERIENNE D’HEMATOLOGIE ET DE TRANSFUSION SANGUINE ALGERIA BUREAU DE LA SOCIÉTÉ MAROCAINE D’HÉMATOLOGIE MOROCCO ADDRESS It is my pleasure to welcome all delegates, both from abroad and from within Libya, on behalf of African Oncology Institute and its academic staff. We are proud and honored to organize Maghrebian Hematology Conference this year. We try to work as a catalyst to bring together people from home and abroad with mutual interest of having a better understanding of hemato-oncologic conditions and advancing the patient care. I hope that the participants will try to extract maximum benefit out of this rare opportunity where so many scientific minds are gathered. I am grateful to all the speakers and presenters from within and outside Libya to make it convenient to attend and make this meeting a success. I hope that the foreign delegates will have an opportunity to see the beautiful coastline, modern fast growing cities of Libya, glorious archeological sites, and local traditional cuisine. I wish they will enjoy traditional hospitality, and will have a comfortable and enjoyable stay. I will also take the opportunity to show my gratitude to all who worked out their best in organizing this conference from its initial plan to final execution. There is always room for improving the endeavors to make the future even better. We are thus open to receive any positive comments and suggestions to improve our future efforts. Dr. Hussein El-Hashmi President, Scientific Committee 7th Maghrebian Hematology Conference III ADDRESS We have been enriched by our experience from organizing international oncology conferences and now this 7th Maghrebian Hematology Conference will add another milestone in our efforts to achieve excellence in hemato-oncology patient management. As obvious from the program schedule, this conference will provide immense opportunities for sharing of experience and knowledge among various international, maghrebian, and national clinicians. With this, our senior managers will recharge and the amateurs will nourish their armaments against disease. The conference is being organized over a period of 3 days and will touch nearly all clinical aspects ranging from problems of epidemiology to recent advancements in stem-cell transplants. This coverage will serve a wider audience and we hope this to reflect as one of our upfront steps and a marker of our concern and motivation for the cause of Libyan patients. In addition, the region of Magreb has similar scenario in the field of hemato-oncology and exchange of ideas on a common podium like 7th Maghrebian Hematology Conference will provide a good opportunity to achieve this. We wish to promote cooperation among south Mediterranean countries in the field of hematology-oncology to improve the outcome in ways of diagnosis and treatment. One of the important arms in our efforts is the release of this abstract book. The book covers essential program details and abstracts including both oral as well as poster presentations. These abstracts include nearly all aspects of hematology and oncology including epidemiology and biotechnology. First section is a tabulated conference schedule. This is followed by section comprised of abstracts from oral presentation sessions while next section includes our poster presentations. Due to inherent limitations, the presentations which could not be included for oral presentations have been shifted to our poster sessions after obtaining consent from their authors. We regret the absence of a few abstract which could not be managed in-time while we aimed for a timely publication of this manuscript. We hope that printing errors will be shadowed by the importance of content and the respect for time. Dr. Abugeila Abussa Secretary, Scientific Committee 7th Maghrebian Hematology Conference IV ADDRESS Imparting scientific knowledge and practical clinical skills is the pivotal exercise of a scientific community. Professionalism, evidence-based medicine, and good clinical practice is the mainstay of any clinical community. Hematology-Oncology has seen and will continue to witness the rapid and fastest growth in research, experience, and clinical practice. New concepts and strategies are incorporated in clinical protocols at a very rapid pace. It is imperative to survive as isolated clinician in a global village. The close collaboration, association, and interaction within the clinical community are the only way to acquire maximum knowledge or experience in a very short life span of a human being. The 7th Maghrebian Hematology Conference will provide a spring board for interaction among the clinical community from within and outside the country. Hands-on workshop will provide an opportunity to the beginners to learn more and can further sharpen their existing skills. The conference will provide an opportunity to share ideas, exchange views, upgrade knowledge, and clear concepts. This will lead to a better understanding of disease process, improving diagnosis, and to have better patient care with improved outcomes. The scientific committee worked hard to give a due and justified representation in the scientific program; according to our local requirements and disease burden. We tried to induct newer subjects and to invite eminent scholars from home, Maghreb, and abroad. The poster presentation will be a valuable academic and research exercise for the participants. We sincerely hope and wish that all the delegates will use this opportunity to its maxim for improving their knowledge and skills with the ultimate aim of improving patient management. We are indebted to those who managed to participate from home and abroad, and we regret that many could not find a place as a speaker or presenter due to limited slots and shortage of time. We will be pleased to have constructive criticism for future endeavors.

Brahimi1, D. Saidi2, A. Arabi1, M. Bey1, H. Berredouane1, N. Yafour1, S. Osmani1, H Touhami2, M A Bekadja1. 1 Clinic of Haematology and Cell Therapy, University Hospital 1st November, Oran Algéria 2 Clinic of Haematology, University Hospital, Oran Algéria Objective: The primary diagnosis of non-Hodgkin`s lymphoma (NHL) based on fine needle aspiration by combining impedancemetry and flow cytometry seems to be good tools. We therefore reviewed our experience with these two methods to determine their usefulness based on the new WHOclassification of malignant lymphoma. Study design: Impedance size distribution histograms and flow cytometry reports of patients who underwent both methods at the same time were examined. Both methods were classified according to the new WHO-classification of malignant lymphoma 2008. Results: There were total 50 cases included in this study. In seven cases FNA failed in gathering sufficient material for immunophenotyping. In ten cases there was no monoclonality B or T (5 Hodgkin’s lymphomas, 3 carcinomas, and 2 lymphadenitis). 33 cases were diagnosed as NHL and were classified on impedancemetry as predominant small cells (19) and large cells (14) and on flow cytometry T NHL (4) and B NHL (29). Light chain restriction was demonstrated in 19/29 cases of B-NHL. With the help of combined impedancemetry and flow cytometry, it was possible to sub-classify 16 cases of the 33 NHL (48%) according to WHO classification. 17 cases were labelled as NHL not otherwise specified (NHL-NOS). Conclusion: Impedancemetry combined with flow cytometry may be helpful in accurately diagnosing and sub-classifying NHL into B or T types and small or large cell types. These methods are not sufficient to sub-classify all lymphomas according to WHO classification and the histopathology remains the main tool for the WHO classification. 3 OR-02 FACTEURS PRONOSTIQUES ET EVALUATION DE LA REPONSE AU PROTOCOLES CHOP OU R-CHOP DES LYMPHOME DIFFUS A GRANDES CELLULES B DU SUJET JEUNE ≤ 60 ANS SE Belakehal, H Mansour, S Baghdad, MC Rahali, D Saber-Cherif, FZ Ardjoun Service d’hématologie, Hôpital Central de l’Armée, Alger, Algérie Introduction: Le début des années 2000 fut marqué par l’utilisation par le groupe d’étude des lymphomes de l’adulte (GELA) de l’anticorps monoclonal CD20, rituximab (375mg/m2) associé au régime CHOP standard chaque 21 jours, dans le traitement de première ligne des lymphome diffus à grandes cellules B. L’addition du rituximab a permis d’améliorer le taux de RC, et le taux de survie. Patients et méthodes: Il s’agit d’une étude rétrospective, entre [mai 2006 et octobre 2009], 72 cas de lymphomes malins, sont colligés. 10 cas de lymphome diffus à grandes cellules B du sujet jeune ≤ 60 ans traités par CHOP (n= 4) ou R-CHOP (n=6). Le nombre de cures est de 6 à 8 cures. L’évaluation a été faite après chaque cure et en fin de traitement. L’âge moyen est de 36 ans [22 et 60 ans]. Le sex-ratio = 2,33 [7hommes pour 3 femmes]. Le délai moyen de diagnostic est de 6 mois [1 mois à 14 mois]. 3 patients ont présenté au départ un problème diagnostique (1 cas avec un carcinome, et 2 cas avec une maladie de Hodgkin). Les signes généraux sont présents dans 8 cas (80%). L’indice de performance est égal à 1 dans 5 cas (50%), et de 2 à 3 dans 5 cas (50%). Le stade Ann Arbor est égal à I, dans 1 cas (10%) / à II, dans 4 cas (40%) / à III, dans 1 cas (10%) / et à IV, dans 4 cas (40%). On a noté 3 cas (30%) avec Bulky, et 8 cas (80%) avec des localisations extra-ganglionnaires. Le taux de LDH est élevé dans 7 cas (70%).

Aftisse, S. Gherras, N. Dali, K. AitSeddik, H. Laga, R. Drif Et H. Ait-Ali. Service d’hématologie CHU Tizi-Ouzou. INTRODUCTION: Les lymphomes malins non Hodgkinien (LNH) sont des hémopathies malignes caractérisés par une prolifération de cellules lymphoïdes monoclonales B ou T dans les ganglions ou les structures lymphoïdes extra ganglionnaires. Leur incidence augmente de façon constante ces dernières années. L’essor des techniques immunohistochimiques et le développement des anticorps monoclonaux ont permis d’individualiser différentes entités de lymphomes B et T et d’adapter la prise en charge thérapeutique. Nous rapportons ici notre expérience sur une période de 06 ans (2004 – 2009). PATIENTS ET METHODES: Il s’agit d’une étude rétrospective faite sur l’analyse des dossiers de malades suivis dans notre service sur une période de 6 ans (2004 – 2009). Les variables étudiées sont: l’âge, le sexe, la localisation du lymphome, le type histologique et le stade anatomoclinique. RESULTATS: Nous avons colligé 155 patients: 81 (52%) hommes et 74 (48%) femmes, sexe ratio: 1,09, l’âge moyen est de 52 ans avec des extrêmes de 17 et 88 ans. Les 155 patients se repartissent en 113 (73%) LNH ganglionnaire et 42 (27%) LNH extra ganglionnaires: 21 LNH digestifs, 08 localisation ORL, 05 localisation osseuses, et 08 autres localisations plus rares: 1 ophtalmique, 2 linguales, 1 massif facial, 1 pulmonaire, 1 cutanée et 1 gynécologique. Selon le stade anatomoclinique: les 113 LNH ganglionnaires sont répartis en 29 (26%) stades localisés et 84 (74%) stades étendus. Les 42 LNH extra-ganglionnaires sont répartis en 29 (69%) stades localisés et 13 (31%) stades étendus. Sur le plan histologique (immunohistochimie (IHC) faite chez 103 patients): 99 (64%) sont des LNH de haut grade de malignité, 56 (36%) sont des LNH de faible grade de malignité. CONCLUSION: Les LNH sont des hémopathies malignes dont la classification anatomopathologique reste difficile et dont 1/3 de nos patients ne sont pas classés sur le plan immunohistologique. Les localisations ganglionnaires restent classiquement les plus fréquentes. 75% de nos patients sont des stades étendus, expliqués par les consultations tardives des patients. 8 OR-04 TUNISIAN EXPERIENCE IN THE TREATMENT OF AGGRESSIVE NON HODGKIN’S LYMPHOMA IN ADULTS: ABOUT 337 PATIENTS Mohamed Adnène Laatiri GELT group From January 1997 to December 2005, 337 patients with aggressive non Hodgkin’s lymphoma were treated with one of the two successive multicentric non randomized protocols established in Tunisia. The mean age was 53 years. Most patients had diffuse large cell lymphoma with B phenotype in 86 % and T in 14 %. The performance status was 2 or 3 in 34 % of cases. The LDH were elevated in 74 % of cases. Advanced disease (III or IV stage) was noted in 59 % of cases and 10 % had a tumoral mass greater than 10 cm. According to the international prognostic index (IPI) adjusted to age, we distinguish four groups: group 1 (0 factor and age < 70 years), group 2 (1-3 factors and age ≤ 60 years), group 3 (1-3 factors and age between 61 and 70 years) and group 4 (1-3 factors and age > 70 years). The patients of group 1 (n=47) received 3 courses of CHOP regimen followed by irradiation. The patients of group 2 (n=160) received 4 courses of ACVBP regimen (+ Rituximab for 21 patients) followed by consolidation (n=92) or peripheral blood progenitor cell transplantation (n=20). The patients of group 3 (n=61) received 8 courses of CHOP regimen (+ Rituximab for 20 patients). The patients of group 4 (n=69) received 6 courses of miniCEOP regimen (n=48) or 6 courses CVP regimen (n=21). The 4-year overall survival was 56 % and the 4-year event free survival was 49 %. 9 OR-05 AGGRESSIVE B-CELL LYMPHOMA Norbert Scmitz Abstract not received till going to publication. 10 OR-06 MEDIASTINAL LOCALIZATION OF NON-HODGKIN LYMPHOMA: DIAGNOSTIC THERAPEUTIC AND PROGNOSTIC APPROACH C. Aboura L. Louanchi S. Nekkal M.Ramaoun Z.Kaci M. Belhani Hematology Department / Blood banking centre, CHU Beni Messous Algiers Algeria INTRODUCTION: Involved mediastinal site during non-Hodgkin lymphoma is characterized by a relatively high frequency, the diagnosis can be difficult in the presence of isolated mediastinum and poor prognosis when there are signs of compression requiring emergency treatment. PATIENTS AND METHODS: We report the results of a retrospective study over 4 years: from 2006 to 2009. 118 lymphomas were supported in our service, with 30 mediastinal localization (25%). The sex ratio is 0.9 (14 ♂ and 16 ♀). The average age is 27 years with a range [18 -53 years]. The period between first symptom and diagnosis ≈ 06 months. A vena cava syndrome with signs of compression was noted in 21 cases (70%) and thrombosis of the vena cava in 02 cases. In 6 patients an extra node affection is found (ovary, thyroid...). A Bulky affection is present in all patients The diagnosis is cytological and histological. Lymph node biopsy (16 cases); trans thoracic biopsy (11 cases); Fine needle aspiration biopsy and bone marrow biopsy (03 cases). The histology: diffuse large B-cell lymphoma CD20 + (21 cases), lymphoblastic lymphoma (04 cases), centrocytic lymphoma (01 case), Not specified (04 cases), the immunohistochemistry is routinely performed: Type B (21 cases) and Type T (04 cases) Not specified (05 cases). Clinical stages localized (18) extended (12) General symptoms: B (26) A(04).Prognostic factors according to IPI low (03), lower intermediate (15), intermediate high (07), high (05). The following protocols were used: RC2H20PA CHOP RCHOP LINKER R Fludarabine COP Results: Complete remission 6 cases (20%) ; Partial remission 12 cases (40%). The shortening of diagnosis time and the use of more aggressive protocols should improve therapeutic results. 11 OR-07 ADULT HODGKIN LYMPHOMA (HL) TREATMENT IN TUNISIA Ben Lakhal R le groupe d’étude du lymphome hodgkinien de l’adulte The first Tunisian adult HL treatment consensus was elaborated in 1999: Prospective non randomized national trial (1st version: MDH 99). This strategy was based on the use of the EORTC prognostic factors in early stage HL and the use of ABVD regimen: 3 cycles for favorable (Fav) early stage (G1) 6 cycles for unfavorable (unfav) early stages (Gr 2) and stage III A (G3) and 8 cycles for advanced stages. Involved field (IF) radio therapy (RT) at 36 Gy was combined to chemotherapy (CT) for early stage and stage III A. At the first analysis of MDH 99 in October 2001, 2 problems were detected: High treatment failure rates (42%) and high number of early relapses in advanced stages. To solve these 2 problems, a second version of the prospective national protocol was elaborated in 2002 (MDH 2002). In this version advanced stages were staged according to the international prognostic scoring (IPS) Intensive CT (4 escalated BEACOPP + 4 Baseline BEACOPP) was used for un Fav advanced stages (IPS ≥3): G4, GCSF was given after each escalated BEACOPP course. Fav advanced HL (IPS ≤ 2) received 8 ABVD (G5) Between 2002 and 2006, 251 consecutive eligible patients from 6 Tunisian departments with newly diagnosed HL were enrolled in this prospective trial (MDH 2002) Results: Median age at presentation was 31 years (range 15-70) with 140M and 111F. 50 % patients (pt) had advanced disease and 44% pts had Bulky mediastinal disease and 69% had B symptoms. 40% pts were treated in G2, 29% in G4, 17% in G5 and only 9% in G1. Eleven (4.3%) toxic death were observed during treatment including 10 deaths in the 72 pts treated with escalated BEACOPP. Of the remaining pts, 83% had CR and 17% had primary failure at the end of the planned treatment (14% with response < 50% and 3% with response between 50 and 75%). Twenty five relapses (12%) were observed with a median time to relapse of 9 months: 9 (10%) in G2, 6 (8%) in G4 and 10(23%) in G5. Five years OS, EFS and RFS were respectively 88%, 73% and 88%. In multivariate analysis, the unfavorable prognostic factors emerging were 12 Bulky mediastinal disease for EFS (55% vs 80%, p = 0.03) and remission status at the end of therapy which influenced EFS (87% vs 50% vs 5%, p = 0.0000) and OS (96% vs 62% vs 55%, p = 0.001). Conclusion: The high rate of relapse (23%) in fav advanced HL (IPS ≤ 2) and the adverse prognostic factor of mediastinal bulky disease were the major issues detected in MDH 2002. To solve these 2 problems a new prognostic staging have decided in third version of the national protocol (MDH 2008) including 3 stages: Favorable (Fav early stage), intermediate (unfav early stage with no bulky mediastinal disease) and unfavorable (stage II+ bulky mediastinal disease, stage III and IV). Intensive chemotherapy (4 escalated BEACOPP + 4 baselines BEACOPP) is currently the treatment of unfavorable stages. The MDH 2008 is used in Tunisia since 2008, results are ongoing 13 OR-08 CONVENTIONAL AND MOLECULAR CYTOGENETIC (FISH) FOR ASSESSING DIAGNOSIS AND PROGNOSIS OF HEMATOLOGIC MALIGNANCIES S. Taoussi, M. T. Abad Department of Haematology, EHS ELCC Blida, Algeria Introduction: Fluorescent in situ hybridization (FISH), providing additional diagnostic, therapeutic and prognostic factor in the evaluation of hematologic malignancies. To improve diagnosis and treatment of hematologic malignancies in our country, we apply the cytogenetic examinations. Methods: We present the results of 136 hematologic malignancies typed by these procedures (chronic myelogenous leukaemia (CML), chronic lymphocytic leukaemia (CLL), multiple myeloma (MM), acute leukemia) (ALL). For each patient, we perform a metaphase and interphase FISH using a panel of probes dedicated to each disorder: CML: bcr-abl probes single and or double fusion; CLL: CEP 12 probe, 13q14-q34 probe, ATM-p53, 6q21 probe. AML: CBFB t (16, 16) inv (16) probe, AML / ETO t (8; 21) probe, PML / RARA t (15, 17) probe, MLL (11q23) probe; ALL: bcr-abl simple fusion probe; myeloma: 13q14-q34 probe. Results: 136 malignancies were studied: CML: 54 cases, LLC: 34 cases, MM 30 cases, LAA: 18 cases. CML Group: CML in chronic phase: 67 examinations of 54 patients: - 31 at diagnosis (30 in chronic phase and 1 in blast crisis). The signal fusion Bcr-Abl was found in 30 cases, 1 case confirming a complex abnormality t (1, 9, 22) found on the karyotype. - 23 in therapeutic evaluation: 20 in chronic phase at 3, 6, 9, and 12 months of taking imatinib, 3 cases in acutisation, for assessing results of therapy. CLL Group: 34 patients: 12 including seven isolated trisomy 12, twelve 13q14deletions including nine isolated (two: loss of 2 copies and two: loss of one copie), 5 ATM (11q22.1) deletions with two isolated, 4 P53 deletions all associated, three 6q21 deletions associated with ATM, p53 and 13q14, no abnormality in 7 cases. Myeloma Group: 14 of 30 patients with a 13q14 deletion and 4 cases with abnormal numbers. ALL Group: 7 LAL: failure of 1 in culture, presence of bcr-abl signal in 2 / 6 cases. AML: 11 cases: PML-RAR positive in a case of LAM3. invert 16: 2/4 cases; t (8; 21) and MLL 14 gene rearrangement studied in 5 cases of AML2, results in progress. Comments: The assessment of therapeutic response to imatinib by karyotyping and metaphase /interphase FISH allowed us to exercise our terms of monitoring cytogenetic remission patients and guide the therapeutic approach. In chronic lymphocytic leukaemia, the importance of abnormalities of poor prognosis (ATM del, p53 del) and atypical (+12) gives a specific profile for our patients to be confirmed on a larger series. In multiple myeloma: the rate of del 13q14 joined that of the literature. The prognostic evaluation of LA is in progress. 15 OR-9 CYTOGENETICS ASPECTS OF ACUTE MYELOBLASTIC LEUKAEMIA IN ADULTS IN MOROCCO M Lamchahab Abstract not received till going to publication. 16 OR-10 ASPECTS CLINIQUE, BIOLOGIQUE ET THERAPEUTIQUE DES LEUCEMIES AIGUES MYELOBLASTIQUES CHEZ L’ADULTE N. Dali, K. Ait-Seddik, M. Allouda, O. Ouanes, S. Gherras, H. Aftisse, H. Ait-Ali Service Hematology Chu Tizi-Ouzou, Algeria Introduction: Le pronostic des leucémies aigues myéloblastiques (LAM) aussi bien de l’enfant que l’adulte est péjoratif. L’allogreffe de moelle osseuse permet d’améliorer la survie et espérer la guérison. On se propose de rapporter dans ce travail, les résultats thérapeutiques de 148 patients adultes colligés sur une période de 10 ans. Patients et méthodes: Patients: de 2000 à 2009 nous avons répertorié 147 de LAM, les extrêmes sont de 15 ans à 82 ans avec une moyenne d’age de 43 ans, 57 sont de sexe masculin et 90 de sexe féminin avec ratio H/F: 0.60. Méthodes: les 147 patients sont diagnostiqués par la cytologie classique (FAB) sur frottis sanguin et médullaire colorés au MGG, complétés le plus souvent par une coloration spécifique au noir soudan. Il s’agit: de 93 LAM2 (69%): 27 LAM1 (20%), 05 M4 (04%), 05 M5 (04%), 03 M6 (03%). Les signes cliniques les plus fréquents: la pâleur cutanéo-muqueuse (94%), le syndrome hémorragiques (54%) et le syndrome infectieux 34%. Le syndrome tumoral a été retrouvé chez 39 patients (26%). Sur le plan biologique: l’hémogramme a objectivé: une anémie chez 139 patients. Le taux d’hémoglobine moyen est de 07,2g/dl une hyperleucocytose > 50.000/mm3 chez 28 malades (27%) avec un taux moyen 47171/mm3. le taux de plaquettes varie de 9000/mm3 à 190000/ mm3 correspondant à un taux moyen de 49119/mm3. La CIVD a été positive chez 30 malades (20%). Traitement: Le traitement comportait la rubidomycine et l’aracytine chez 103 patients les autres ont reçu d’autres thérapeutiques. 17 Résultats: Sur les 147 patients, seuls 114 sont évaluables, 33 n’ont reçu aucune thérapeutique spécifique, ils sont décédés précocement. Parmi les 114 évaluables, 31 (27%) sont décédés pendant l’induction. 60 (72%) sont mis en RC dont la médiane est de30mois (03 mois – 117 mois). 38 sur 60 sont toujours vivants au première RC dont 25 parmi les greffés. 02 sont décédés après greffe. Conclusion: Le pronostic des leucémies aigues myéloblastiques reste mauvais, mais la greffe de moelle osseuse allogenique a permis d’améliorer la survie à long terme pour les patients en rémission et ayant un donneur HLA compatible. 18 OR-11 AML Bacigulapo Abstract not received till going to publication. 19 OR-12 MANAGEMENT OF ACUTE MYELOBLASTIC LEUKAEMIA IN ADULTS: MOROCCAN EXPERIENCE A.Quessar Abstract not received till going to publication. 20 OR-13 ACUTE MYELOID LEUKEMIA, A PROSPECTIVE STUDY OF 83 TUNISIANS PATIENTS Ben Amor R, Jeddi R, Ben Neji H, Aissaoui L, Kacem K, Bouteraa W, B. Abdennebi Y, B. Lakhal R B. Abid H, Belhadjali Z, and Meddeb B Department of Clinical Hematology, Aziza Othmana Hospital, Tunis Objective: The main objective of this study was to evaluate the therapeutic results in AML young patients treated according the national Tunisian protocol and to compare the prognostic to literature and suggest any changes to improve their issue. Patients and Methods: In our prospective study, between January 2003 and December 2006, 83 de novo AML patients aged between 18 and 55 years were included (acute promyelocytic leukemia was excluded). They were diagnosed and treated, according to the national protocol, in the Hematology Clinical Unit of AZIZA OTHMANA hospital. Results: The median age of our patients was 41 years. The karyotype was normal in 47.2 % of cases. According to “the Medical Research Council cytogenetic risk group”: 13.5% of patients were low-risk, 77% intermediate risk and only 9.5% were high risk. The Complete induction-remission rate was 75.9%. Among clinical and biological parameters analyzed at diagnosis, only karyotype influenced the achievement of complete remission: 100 % in low risk group, 82.6% in intermediate risk group and 28.5 % in high risk group (p = 0.006). Induction mortality was 16.8% caused by an infectious cause in 71% of the cases. The 4-years overall survival was 48.6%. The 4-Years relapse-free survival was 34.9%. The global relapse rate was 41.2%. Relapse-free survival at 18 months was 55% in intermediate risk, 0% in high risk and only 18.5% in low risk (p = 0.05). Univariate study revealed that; age between 18-50 years (p = 0.05), myelo-peroxydase positivity (p = 0.04) and nonexistence of a HLA identical donor (p = 0.03) influenced favorably the overall survival. Multivariate study revealed that mortality relative risk was 3.96 for patients older than 50 years. Conclusion: We note that our results are approximating those reported in literature data (excluding the worse issue of our low risk group patients). We also believe that these results could be improved by: increasing alloSCT number, a better supportive care and a better molecular follow up. Finally, we have to re-consider the place of AutoSCT, as an alternative post induction therapy, because of the poor development and the limited indications of allograft in our country. 21 OR-14 ASPECTS CLINIQUE BIOLOGIQUE ET THERAPEUTIQUE DES LEUCEMIES AIGUES LYMPHOBLASTIQUES DE L’ADULTE K.

Introduction: Imatinib was the first treatment for chronic myeloid leukemia (CML) that specifically targeted the causative BCR-ABL transcript, producing high response rates in most patients. In this multicentre study, we retrospectively evaluate cytogenetic and molecular response to Imatinib and analyze the predictive resistance factors and their impact on event free survival (EFS) and overall survival (OS). Patients: From July 2002 to June 2009, 116 CML patients were included: 104 in chronic phase (CP) and 12 in accelerated phase (AP). Median age was 44 years (13 – 76 years). BCR-ABL transcript was initially studied in only 81 patients (70%). Sokal score, calculated in 110 patients, was high in 21 cases (18%), Intermediate in 53 cases (46%) and low in 36 cases (31%). Methods: First-line treatment in all patients was Imatinib 400mg/day, initiated in a median of 3 months (1-12months). ELN criteria were used for response evaluation. Results: Complete cytogenetic response (CCyR) was achieved in 76% of cases with a median of 12 months (3-36 months). Molecular monitoring was performed in 80% of patients. Major molecular response (MMR) was achieved in 62% of cases with a median of 18 months (6-48 months). 33% of patients were in optimal response (OpR), 46 % in suboptimal response (SubOpR) and 21% in primary resistance (PR). 11% of patients had a secondary resistance. Imatinib dose escalation benefit to 18/25 patients in PR (72%). Only five of them did achieve a CCyR. Predictive factors of CCyR were Sokal score and treatment discontinuation (toxicity or non adherence). Sokal score was the only predictive factor of MMR. The 5 years EFS was 79%. EFS varied significantly according to 6 months CCyR (92% vs 58%, p=.00001), to initial disease status (CP: 87% vs AP: 58%; p=.002) and to initial response (PR: 87% vs OpR-SubOpR 68%, p=.008).The 5 years OS was 88%. Only CCyR had a significant impact on OS. MMR had no impact neither on EFS nor on OS. 24 Conclusion: In our study we note that management of resistance and suboptimal responses was not harmonized. In fact, Imatinib dose escalation benefit to only 42 % of patients eligible for escalation (38/91). Despite this difficulty EFS, OS and CCyR are hopeful and may be improved by better management synchronization. We note also that maintain and escalation of Imatinib permitted the reaching of CCyR in some cases but did not increase survival. The recent use of second generation tyrosine-kinase inhibitors drugs may also contribute to improve the outcome of these patients. 25 OR-16 NEW TREATMENTS FOR FIT AND UNFIT PATIENTS WITH CLL Marco Gobbi University of Genova Italy Chronic lymphocytic leukemia has been for long time a sort of “Cinderella” for biological understanding and treatment approaches. In recent years the entire issue has evolved rapidly and now several therapeutic strategies are available for different clinical situations. If the reduction of the disease expansion and the steady state maintenance has been the goal in the past, at present for the first time fit patients could experience molecular remission that can greatly influence progression free survival and overall survival. The standard treatment is the combination of Fludarabine cyclophoshamide and Rituximab (FCR) recently introduced by the german group that significantly increase the results in all fit patients except in those bearing 17 p– chromosomal abnormality. In these patients Flu – Cam protocol (Fludarabine plus Alentuzumab (Camparth) seems to offer better results; however in selected patients allogeneic stem cell transplant should be offered. For older patients and for those with comorbidities there are several possibilities: low dose FC + R, Chlorambucil + R and Bendamustina +R are the most used protocols. In these patients although an effective increment of the overall survival duration has not jet demonstrated, the percentage and the quality of the remission obtained are significantly increased. The appropriate evaluation of the biological risk for each patient in a hand and the introduction of Rituximab in the majority of patients and Alentuzumab in selected ones in the other, have greatly contributed to the recent advances in this disease. Now a new generation of anti CD 20 monoclonal antibodies is being evaluated in clinical trials and is expected to even increase the results in the next future. 26 OR-17 ADVANCES IN MANAGEMENT OF MULTIPLE MYELOMA Moulod EL-Agnaf In recent years, our understanding of the biology of multiple myeloma has vastly improved. As a result an array of effective treatments were developed. Survival in multiple myeloma has improved, although in the vast majority of patients, myeloma remains an incurable disease. In my short talk, I will focus on the recent development in treatment. I will also discuss a number of practice changing clinical trials in myeloma. 27 OR-18 TREATMENT OF MULTIPLE MYELOMA IN THE DEPARTMENT OF HAEMATOLOGY AND BONE MARROW TRANSPLANTATION – EHU 1st NOVEMBER 1954 - ORAN –ALGERIA A.Arabi, F.Attaf, M.Bey, B.Benzineb,N.Yafour, H.Berredouane, B.Enta Soltane, S.Osmani, M.Brahimi, H.Tedj, N.Bahlat, MA Bekadja Therapeutic options for multiple myeloma (MM) patients have changed quickly in recent years and uncertainty has arisen about optimal approaches to therapy. A reasonable goal of MM treatment in younger “transplant eligible” patients is to initiate therapy with a target goal of durable complete remission In our service, between 1st August 2007 and 31 January 2010, we have treated 48 patients with Multiple Myeloma: -Age: 64,2 years (37 – 83) -Sex Ratio: 1,63 -diagnosis was based on clinical features, X-ray of bones, bone marrow aspiration, protein electrophoresis, identification of the serum monoclonal protein (in some cases), presence of Bence Jones protein (in some cases) -complications like elevation of calcium were identified and treated -ISS classification was adopted For the treatment, we distinguish two periods: Before November 2008, patients were treated essentially by Alexanian protocol After November 2008, National consensus was adopted: * Patients < 65 years: Cyclophosphamid-Thalidomide-Dexamethasone or BortezomidDexamethasone: if complete response, autologous bone marrow transplantation * Patients > 65 years: Melphalan-Prednisone-Thalidomide 28 OR-19 PRELIMINARY RESULTS OF BORTIZOMIB–DEXAMETHAZONE PROTOCOL FOLLOWED BY THERAPEUTIC INTENSIFICATION BY MELPHALAN 200 AND AUTOLOGOUS STEM CELL TRANSPLANT IN MULTIPLE MYELOMA N.

Bey, MA Bekadja Hematology and Cell Therapy department, University Hospital “1er Novembre” Oran Algeria Introduction: Multiple myeloma is a haematological malignancy that has gained many therapeutic advances these last years. It is believed that obtaining a complete remission after a therapeutic intensification followed by autologous stem cell transplant is the only guaranty of a long survival. Our study is a preliminary evaluation of Bortizomib-Dexametazone protocol as an induction therapy followed by 200mg/m2 conditioning regimen in multiple myeloma. Patients and methods: In May 2009 we have started a prospective study concerning patients with multiple myeloma, less than 65 years old, with no co morbidities. The induction therapy combined Bortizomib 1,3 mg/m2 D1, D4, D8, D11 and Dexamethazone 40mg/m2 D1 to D4; D8 to D11; D15 to D18 from the 1st to 2nd cycle and from D1 to D4 form 3rd to 4th cycle, with one cycle each 28 days. The evaluation of the remission was done according to the EBMT criteria. Stem cell mobilisation was accomplished with G-CSF 15μg/kg for 5 successive days. Stem cell collection was preformed by cytapheresis then an intensification with Melphalan 200mg/m2 (MEL200). The graft has been stocked in refrigerator at +4°C for 24 to 48 hours then reinfused 24 hours after intensification by MEL200 The post-transplant evaluation was preformed at D100. The maintenance therapy with Thalidomid 50mg/d and Acetylsalicylic Acid 100mg/d was introduced at D30. Results: From May 2009 to February 2010, seven (07) patients with multiple myeloma and less than 65 years old were included in the study. Six males and one female with a median age of 51 years [34 to 57], ISS stage: 6 intermediate and 1 low. 5 patients had received 2 lines of regimens and 2 patients were newly treated. 29 Median time of follow-up: 03 months and post-transplant status was as follows: 5 CR and 2 VGPR. Conclusion: Even if this study is preliminary it shows that the induction with Bortizomib – Dexamethazon is very useful to maintain a complete remission 30 OR-20 TREATMENT OUTCOME OF THALIDOMIDE BASED REGIMEN IN NEWLY DIAGNOSED AND POST AUTOLOGOUS STEM CELL TRANSPLANTATION MULTIPLE MYELOMA PATIENTS: A TUNISIAN EXPERIENCE Lakhal A1, Ladeb S1, Torjman L1, Bettaieb J2, Abdelkefi A1, Ben Abdeladhim A1, Ben Othmen T1 Centre National De Greffe De Moelle Osseuse De Tunis Tunisie Département de médecine préventive et communautaire. Faculté de médecine de Tunis Introduction Thalidomide in combination with dexamethasone (TD) as short upfront therapy has demonstrated improved response rates and progression-free survival rates compared to dexamethasone alone and VAD in previously untreated multiple myeloma (MM) younger patients. In the setting of post-autologous stem cell transplantation (ASCT) therapy, thalidomide maintenance resulted in significant benefit in terms of event free survival (EFS) and progression free survival (PFS); however, overall survival (OS) was improved in only some studies. Purpose The aim of this retrospective study is to update outcomes of TD as initial front line treatment in newly MM patients undergoing ASCT and to assess potential benefits with thalidomide as maintenance therapy after ASCT. Patients and methods Untreated Durie-Salmon stage II or III MM patients younger than 65 years, received first-line therapy combined thalidomide at a dose of 200 mg per day for 75 days and dexamethasone at a dose of 20 mg/m2 body surface area on days 1 to 4, 9 to 12 and 17 to 20 on the first and third month of therapy and 20 mg/m2 body on days 1 to 4, the second month. Almost all patients were administered associated thromboprophylaxis to TD. To proceed to peripheral blood stem cells (PBSCs) collection after first-line therapy, either high-dose cyclophosphamide (HD-CY) (4g/m2) and granulocyte colony-stimulating factor (G-CSF) (5 μg/kg/day) starting on day+3 from HD-CY or G-CSF alone (10μg/kg/day) on days 1 to 5 was used. PBSCs were harvested usually between days + 11 and days+13 after HD-CY. A minimum of 3 million CD 34+ per kilogram was collected. Conditioning regimen preceeding ASCT consisted on Melphalan (200mg/ m2). G-CSF was administered from day+5 after stem cells transplantation until neutropenic engraftment. Between April 2003 and December 2006, patients were included in a randomized study comparing tow arms, arm A: tandem ASCT within 6 months of the first ASCT with the same conditioning regimen and arm B:one ASCT followed by 6 months maintenance therapy with thalidomide at a dose 100 mg per day starting 3 months post-ASCT. A second ASCT was received in case of relapse or disease progression after maintenance therapy. At the end of this randomized study, all patients were treated after induction therapy by ASCT followed by thalidomide maintenance therapy. The 31 response criteria used in this study were based on the European Group for Blood and Marrow Transplantation and the International Myeloma Working Group Uniform Response Criteria. Evaluation of response to TD was performed after the end of induction therapy, before ASCT, every three months after ASCT and thalidomide maintenance therapy. Results Between April 2003 and October 2009, 137 patients (58 female, 79 male) with newly diagnosed MM received front-line therapy with TD. Patient’s characteristics are summarized on Table1. Table1.

A peripheral blood stem-cell collection was performed in all patients. A median number of 9.71million CD34 cells per kilogram were collected (range, 1.68-76). The median time from diagnosis and ASCT was 8 months (range, 1-23). In the tandem ASCT group (n=36), 27 patients (75%) underwent a second transplantation. In the thalidomide maintenance group (n=101), 23 patients (46%) have a second transplant for a progression or disease relapse and 76 patients (75%) received maintenance therapy by thalidomide. The median time from the first to the second transplantation was 7 months (range, 2-59 months). The overall response rates (ORR) at the end of induction therapy, prior to high dose therapy and after thalidomide maintenance therapy are shown in table 2. 32 Table 2.

Three year overall survival in tandem ASCT patients and in thalidomide maintenance post transplant therapy patients were 51.8, 72.4% respectively (p=0.05). Conclusion Our study demonstrates that thalidomide combined with dexamethasone used as front-up short induction therapy prior to ASCT was an effective therapy in MM untreated MM patients. In addition, thalidomide administered as maintenance therapy provided impressive survival benefit. 33 OR-21 ANALYSE CYTOLOGIQUE ET IMMUNOCHIMIQUE DE 40 CAS DE MYÉLOME MULTIPLE À CHAÎNES LÉGÈRES = CYTOLOGICAL AND IMMUNOCHEMICAL ANALYSIS OF 40 CASES OF LIGHT CHAIN MULTIPLE MYELOMA MC Rahali ; L Bouteldja ; SE Belakehal ; S Baghdad ; FZ Ardjoun; Service Hématologie HCA ; Alger ; ALGERIE Nous rapportons dans ce travail une analyse clinique, cytologique et immunochimique de 40 cas de myélome multiple à chaînes légères, colligés au Service Hématologie /HCA depuis 20 ans (1990-2010), représentant 33% de l’ensemble des malades myélomateux répertoriés pendant cette période, sex-ratio= 1, avec un age moyen 64 ans (extrêmes 46-74 ans).

The great diversity seen in this group of disorders is a reflection of the complexity of normal haematopoiesis and the immune system. Aim of the study: The study was designed to present: 1) The demographic characters of the Libyan patients with hematological malignancies in Benghazi in the year 2009. 2) The incidence of the hematological malignancies among Libyan population in Benghazi in the year 2009. 3) The pattern of hematological malignancies in Benghazi in the year 2009. 4) The incidence of death among Libyan hematological malignancy patients in Benghazi in the year 2009. Material and Method A retrospective study was carried out in “hematology unit at “ Jamhoria hospital”, Benghazi. The data was extracted from the files of hematological malignancy patients who were diagnosed in the year 2009. SPSS was used for data analysis. Statistics used; mean, standard deviation, median and percentages. Incidence rates and mortality rates among the patients were also calculated. Results: 71 cases of malignant hematological diseases were registered in the year 2009 in the hematology unit at Jamhoria Hospital. Male to female ratio was 1.4: 1, the age of the patients ranged from 18 to 100 years, median age was 54 years, the overall incidence of hematological malignancy among Libyan population in Benghazi was 17.74 per 100000, the most frequent malignancy was Non Hodgkin lymphoma (25.35% of all the cases) and its incidence was 4.5 per 100000. Acute lymphocytic leukemia, myelofibrosis, and Waldenstrom’s macroglobulinemia had the lowest frequencies (1.41% of all the cases), their incidence was 0.25 per 100000. By the end of the year 36 2009, 8 out of the 71 cases were died with mortality rate of 11.27%. Conclusion: In conclusion the distribution of the various hematological malignancies in this study is similar to the pattern reported in other studies. There appears to be generally a lower incidence of hematological malignancies recorded when compared to other studies. Late presentation, interference with the early start of treatment by the patients’ family as well as shortage of supportive treatment were the most common cause of death. 37 OR-23 DESCRIPTIVE STUDY OF SERIES OF 104 PATIENTS AFFECTED BY HAEMOPHILIA N.Saidane*; Y.Ouarhlent* ; C.Derdous** ; M.Saïdi*. *Haematology, University Hospital;**Orthopedic department, University Hospital, Batna, Algeria. Haemophilia prevalence in Algeria reached of 1445 cases counted until March 2010. Despite the project of haemophilia national register, we remain far from real assessments because of the misunderstanding of this pathology in a lot of regions in Algeria. The main objective of this study is to obtain exhaustive information on the characteristics and the evolution of haemophiliacs managed by University Hospital of Batna (south east Algeria), which represent 7, 26 % of the estimated number in all algerian territory. Patients and methods: This is a prospective monocentric study about 104 patients affected with haemophilia (A or B), living in the region of Batna and its neighborhood, including 63 adults and 41 children. Those patients had come either directly to haematology consultation at University Hospital of Batna, or they were oriented to us by the other nearby structures. Results: Among 104 patients, 82% had type A haemophilia, of which 78 % severe forms, 20 % moderate forms and 2 % minor forms. Haemophilia B occupies 18 % with 63 % for severe forms, 32 % moderate forms and 5 % minor forms. Patients have a median age of 19 years (1 month- 52 years) and 85 % of them are less than 30 years old. About 33% of patients did not report any family history, and 63 % of them have at least an affected brother. Viral infections were stated at 58 patients among whom 1 patient was infected by HIV and 9 patients by HCV.Only 17 patients of the series were vaccinated against hepatitis B. Presence of inhibitors against coagulation factors was checked at 29 patients, and only 3 of them have inhibitors. In the context of multidisciplinary consultation (hematologist, orthopedist, pediatrician and physician doctor), assessment of: age and circumstances of diagnosis, professional activity, handicap degree evaluation, irregular agglutinins research and hemoglobin rate, orthopedic status and its management were stated for 34 patients (12 children and 22 adults) of the series at the cut of the analysis (march 2010). Data analyze showed following results: about 78% of severe haemophiliacs were being diagnosed at around 6 - 12 months of age. The disease is revealed by bruises and/or hematomas in 48 % of cases, haemarthritis, wounds and circumcision in 9 % each of them. Familial inquiry is the origin of diagnosis in 15 % of cases. Only 6 patients from 22 adults reported professional activities. Among 34,twenty three patients totally independent in 38 their displacements and daily activities, and 11 patients need assistance to performing some activities.Irregular agglutinins are absent in those patients, and one patient/ four presents anaemia with haemoglobin rate between 8-10 g / dl. Data about orthopedic status and its management for each of 34 patients will be published. Conclusion: This study takes a census of haemophiliacs managed in our center and performs a preliminary evaluation of complications. That draws many perspectives of work: management of orthopedic complications,care health of HCV+ and HIV+ patients, put an anti-hepatitis B vaccination program for patients not vaccinated, care health of anemia cases, and especially manage patients having developed inhibitors against coagulation factors. That also enables the institution of an adequate prophylaxis schema and estimating financial costs. 39 OR-24 MANAGEMENT OF AML IN CHILDREN: MOROCCAN EXPERIENCE S.Cherkaoui Abstract not received till going to publication. 40 OR-25 BURKITT’S LYMPHOMA IN CHILDREN Hasna Driouchi Abstract not received till going to publication. 41 OR-26 ITP Ramdan Allous Abstract not received till going to publication. 42 OR-27 TRANSPLANTATION FOR MM Nuri Hwaje Abstract not received till going to publication. 43 OR-28 BONE MARROW TRANSPLANT Andrea Bachigulapo Abstract not received till going to publication. 44 OR-29 HIGH-DOSE CYCLOPHOSPHAMIDE, ETOPOSIDE AND BCNU WITH NON-CRYOPRESERVED AUTOLOGOUS HAEMATOPOIETIC STEM CELL TRANSPLANTATION FOR POOR PROGNOSIS HODGKIN’S LYMPHOMA MA. Bekadja, M. Brahimi, N. Yafour, S. Osmani, F. Attaf, F. Tadj, A. Arabi, B. Enta-Soltan, H, Berredouane, B. Benzineb, M. Bey, N. Bahlat. Clinic of Haematology and Cell Therapy, University Hospital 1st November, Oran Algéria Several high dose chemotherapy regimens have been used in autologous transplants for Hodgkin’s lymphomas (HL). Most of these high-dose therapy schedules were designed to deliver cytotoxic drugs over a number of days [e.g. 6 days for BEAM, CBV or ICE], freezing of the harvest product was traditionally carried out to maintain cell viability until stem-cell reinfusion. Unfortunately cryopreservation unities are not available in many developing countries so the liquid storage of harvested stem cells, in standard blood refrigerators, is an alternative to cryopreservation. The aim of this study is to demonstrate the feasibility and safety of autotransplants with noncryopreserved peripheral blood stem cells. 10 patients with poor prognosis malignant Hodgkin’s lymphoma were treated with high-dose cyclophosphamide (120 mg/kg), etoposide (2100 mg/m2) and BCNU (400mg/m2) followed by reinfusion of autologous non-frozen PSC, which had been stored for 72 hours at 4°C. The median time to achieve an absolute neutrophil count greater than 0.5_109/l was 13 days (range 11–20 days). The median time to self-sustained platelet count greater than 20_109/l was 20 days (range 15–30 days). Eight of the 10 patients are still alive and disease free and one patient died of severe infection. We conclude that high-dose chemotherapy with non-frozen autologous bone marrow transplantation is safe in terms of haematopoietic reconstitution and the preliminary follow-up data suggest a useful efficacy. The procedure is easy to perform without requiring costly cryopreservation. 45 OR-30 LIBYAN EXPERIENCE IN BMT Nabila Sassi Abdulrahman African Oncology Institute, Sabratha, Libya Hematopoietic SCT is now an established treatment modality with definitive indications for many hematological disorders. However, this line of treatment requires tremendous resources, and it becomes increasingly difficult for transplanters practicing in the developing world to reconcile the difference between what is possible and what is available. The SCT program in Libya started in 2007 on a narrow scale. In 2009 the transplant rate increased dramatically. The total number of transplants performed till April 2010 is 15 cases all are autologous. 46 OR-31 ALLOGENEIC HEMATOPOIETIC STEM CELL TRANSPLANTATION FOR 37 PATIENTS WITH FANCONI ANEMIA R. Ahmed Nacer, F. Mehdid, N. Rahmoune, M. Benakli, R. Belhadj, M. Baazizi, F. Harieche, F. Zerhouni, RM. Hamladji Departement of hematology and BMT unit, Pierre and Marie Curie center, Algiers, Algeria Introduction: Fanconi anemia (FA) is an autosomal recessive disease frequently evolves to bone marrow failure and acute myeloid leukemia. Allogeneic hematopoietic stem cell (HSCT) is the treatment of choice for patients with FA, it leads to normal complete hematopoietic recovery and prevention of acute leukemia. Materials and methods: From June 1998 to November 2008 (125 months period) 37 patients with FA underwent 38 allogeneic HSCT (from HLA-identical sibling donors: 32 and pheno identical: 4, mismatch cord unrelated donor: 1); median age 11 years (5 to 24); sex ratio (M/F) 1; median interval from diagnosis to transplant 24,9 months (5 to 60); 12 patients (44,3%) had received more than 20 transfusions before allograft. Two conditioning regimens was used: BU-Cy protocol with busulfan 6 mg / Kg and cyclophosphamide 40 mg/Kg for 9 patients (23,7%) and Flu-Cy-ATG protocol with fludarabin 150 mg /m2, Cy 20 mg/kg and anti thymocyte globulin (Fresenius) 40 mg/Kg for 28 patients (73,7%). GVHD prophylaxis associated cyclosporin and methotrexate 5 mg/m2 (J1-J3-J6). Four patients received bone marrow transplant and 31 patients peripheral blood stem cell and 2 patients died before allograft. At May 2009 maximal follow up is 131 months and minimal 6 months. Results: The median time to engrafment was 13 days (10 to 21). Twenty patients (54 %) are alive with success engrafment after median follow up 39 months (6 to126):2/9 patients (22.2%) had BU-Cy conditioning and 18/28 (64.3%) Flu-Cy-ATG conditioning. Late graft failure (J60 to J511) was observed in 5 patients (13,5%). Acute GVHD occured in 13 patients (43,3%) with 10 grade II-IV (33,3%) and chronic GVHD in 5 patients (20,8%) with 3 extensive. Seventeen patients died (45,9 %): 11 patients (29,7%) by transplant related mortality (TRM): infectious: 4, grade II-IV acute GVHD: 4, extensive chronique GVHD: 1, hemorrhage: 2. Six patients by another causes of death: graft rejection: 4, secondary neoplasia: 1, unknown: 1. Actuarial overall survival (OS) is 49,8% at 9 years. TRM was higher in Bu-Cy conditioning group (44,4%) than Flu-Cy-ATG conditioning group (25%; p = 0,07)) and OS is 63% at 9 years in Flu-Cy-ATG group. Conclusion: Flu-Cy-ATG conditioning regimen appears better than BU-Cy. A best outcome can be reached by precoce diagnosis and by reduction of interval from diagnosis to allograft. 47 OR-32 EVALUATION OF PATIENTS WITH MYELODYSPLASTIC SYNDROMES. A RETROSPECTIVE STUDY. S.Bougherira, F.Grifi, B.Rached, H.Mehennaoui. Department of Haematology – CHU ANNABA. ALGERIA Background: Myelodysplastic syndrome (MDS) is a clonal haematopoietic stem cell disorder, characterized by ineffective dysplastic haematopoiesis, and peripheral cytopenias. It is considered a pre-leukemic disease (about 30% of MDS turn into acute leukemia) which is associated with cytogenetic abnormalities. The aim of this study is to collect the epidemiological data and clinical characteristics; and to evaluate the therapy of MDS. Patients and Methods: Retrospective study between 2005 to 2009, including 60 patients treated in our department for MDS. The median age was 59 years (range 10 to 83), gender 30 women and 27 men. The diagnosis is based in analysis of the blood film and the bone marrow aspirate and trephine biopsy. Resultats: Time for diagnosis, varied from one week to 36 months. The mean clinical features of our cohort anaemia’s syndrome was present in all patients, splenomegaly only in 11 % of cases occurs in CMML, recurrent infection and bleeding‘s syndrome. Biological methods found moderate cytopenia; Blood and marrow cytological analysis show, among all patients, signs of dysplastic cells. Perls colouring was used only for 05 patients; cytogenetic analysis was done in three cases (1 pt with normal karyotype, 1 pt with 5q-, 1 pt with complex abnormalities involve chromosome 5 with monosomy 7). The distribution of patients according to classifications’: AR 18 FAB Classification ASIA AREB AREB-t 05 22 08 LMMC 07 AR 15 AS pure 04 WHO Classification AR/CRDM AREB I 12 12 AREB II 10 SMD/SMP 07 While there is new treatment approved for MDS, supportive care remains an integral component of care for these diseases. All patients received supportive care: RBC transfusions for symptomatic anemia as needed, platelet transfusions for thrombocytopenia or bleeding, management of iron overload, and recently hematopoietic growth factors. Chemotherapy in some 48 cases. The only curative treatment is stem cell transplantation. The evolution was marked by occurrence of an acute leukaemia of unfavourable prognosis. Conclusion: MDS are a relatively frequent affection raising difficulties in therapy in spite of the advent of new strategies and new molecules. 49 OR-33 USING COMPUTERS TO IMPROVE DONOR MANAGEMENT AND TRANSFUSION SAFETY Ktari Kamel The objective of transfusion (patient) safety makes blood transfusion increasingly complex. The progress of medicine and the discovery of new pathogens increase the number of tests required. Their modes of contamination and the serological window bring greater complexity in the medical interview and induce complex treatments for securing certain products. The long period of serological window, as well as the fear of presence of unsuspected pathogens forces to maintain traceability over periods exceeding 30 years. Recently this traceability was extended to all staffs, equipments and consumables involved in the process. The multiplicity of tasks, and the vast amount of information to manipulate and then to store make the mission of blood transfusion centres impossible to achieve manually and lead to significant decrease in the patient safety. We will see in this presentation how information technology can help blood transfusion centres to reach their aim and improve the transfusion safety. 50 OR-34 ‹Å’\ ◊Œfi’;ÏË]ÕÊ’\;k\Ô\Öp¸\ ÍÑÊÕÖŒ’\ ÿ˜p ;äÕ]ëd;‹Å’\ ◊Œfi’ ÍÊ‚°\ á—Ö∏\ Î Ûö㇋€ ãíbjæa@àb‘„a ∂g Úœböbi LÂÿ∏ sÓy Ú‘ˆbœ Ú„bÿfl sÌá®a k€a ¿ ‚á€a ›‘„ pbÓ‹‡« Ônÿm ‚á€a ãœÏm Êbÿœ NÔ‡ƒ»€a bɉ€a äå ›rfl ¸ ‚c o„b◊ ÚÓyaãu pbÓ‹‡»€a áÌá« åb≠g Âfl L—Ì „ Ú€by ¿ μibóæa ÏÁ ãÇe ubÁ aâÁ Û‹«@ÜaÜåa@Î NıaÏ€a áy@Û‹« Úzó€a@paäaåÏ€ Î@‚χ»‹€ aj◊ bubÁ Úub®a o”Î Èmb‘nìfl@Î ›◊ ቫ ÚÌäbjua ›Ó€bzn€a Âfl —«bõm@fiÎá€a ›u LÒDza pbÌã컀a ¿ ôÏó©bi Î@Lb‰Ìcä àg ‚á€a ›‘„ Úfl˝ @%100 Új‰i Úfl˝€a Âfl aâËi l‘m bË‹« m ZÚÓbc äÎb´ 3@¿ bËóÓÉ‹m@Âÿ∫ Î@ګωnfl Î@ÒáÌá« paıaãua@ UÏË¡]fi∏\ ÏŸ˜â’\@M1 ÚÓ«b‰æa pb–«bõæa@›◊ Ó€ Î ›u k‰§ Êc bË„bí@Âfl €a Î ÚÌäÎãõ€a ›Ó€bzn€a@áÌá« á≠ fiba aâÁ@¿ N‚á€a ›‘„ pbÓ‹‡»€ ‚aya kuÏnm@Ú‘Ó”Ü Î ÒÜá»nfl@pbÓ‰‘n€ …õ¶ ÚÓ‹‡« ÔÁÎ ZãÁbƒ€a@ÈÓ‡‰m Î Èmãflå@Î@‚á€a Ú‹Óóœ Úœã»fl J NHÚÌäbjnÇg fibóflcI ÒÜÏu paà Ų́ pbfl ‹næ fib‡»na Î ›‡»€a ÚÓvË‰æ ›flb◊ ’ibæa@Óßa Übõæa ‘y k‰§ Âfl Âÿ∏ ÔÁÎ Z㇮a pbÌãÿ€a áö ÚËvnæa ÚÌáßa paÜbõæa « szj€a J Na‹≠g@À ÚÓiãÀa biÎäÎc ¿ bbc Ú‘Ìã€a ÍâÁ ›‡»nmÎ NÌãæa@ቫ ÜÏuÏæa áßa Übõ‡‹€ Êb◊Î Na‹≠gÎ@ÚÓ€b‡ì€a bÿÌãflc@¿ bbc ›‡»nm Î ZÊÏ‘a ‚á€a Î Ìãæa ›ófl@μi ’ibn€a ÚÓ‹‡« ıaãug J N„Ïm äbÓnÇa aâÁ ÚÓ‹‡« « fiÎ˚æa@kÓj€a Èi ‚Ï‘Ì Î@‘®a@›j” Úƒ® ãÇe@¿ ÊÏÿÌ ZÌãæa ãÌã ቫ ’ibn€a Új”aãfl@J ’ibn€a ¿ d©a ubÁ Üb»ig@Âfl ıaãua@aâÁ Âÿ∫ Î NÉæa ¿@ã§@€a Ú‘ib€a pbÓ‹‡»€a ÿ« ‘®a NÒ©aÎ ÚÓj‹€a Èvˆbn‰i “Îã»æaÎ ÊÏ‘a ‚á€aÎ@Ìãæa μi HABOI ’‹»nÌ bfl ›◊@¡jõ€ ›‡»nm Î Ì㇋€ €a —‹æa ¿ ≈–• ÚñbÇ Òàaâu ‡»m ÔÃj‰Ì aâÁ@∂g Úœböbi J 51 NÌ㇋€@ÚÓœbög@Úfl˝ μflbm Âÿ∫ Ú‘Ìã€a ÍâËi@Î NÚ‹væa pb–«bõæa Î ÊÏ‘a ‚á€a Î Èöãfl Î@Ìãæbi UÏ’ÊŒfi∏\ ô\ÖŸ¯\ flŸ;ÏŸ˜â’\ -2 Zo”Ï€a@–„ ¿ Òá»ñc Òá« Û‹« ›‡»€a k∞ fiba@aâÁ@¿ È‘jÌ â€a laÏvn¸a@Âÿ€Î Np¸b®a »i@òÓÉìn€ Ù◊ ÚÓ‡Ác òz–€a aâÁ ÔnÿÌ Z€a òz–€a@J ቫ ãfl äaÏ« c Âfl@ÏÿìÌ@¸ nfl ቫ ‚á€a kz « b‰nfl¸a Âfl@Âÿ∫ sÓy@ȉfl rÿi ·Ác ÏÁ Ûny Ùáæa Ú»aÎ Ózn€a ÚÓ‡Ác Û‰„@Êc k∞ ¸ b‡◊ NÔ‘‹n‡‹€ Új‰€bi aãÇ@›ÿìÌ È„a μy ¿@òz–€a NÔ”aÏ€a fibœã€a ÊÎÜ Î “Îã»fl À òÉí@…fl Ô‰u fibóma Ô‹m €a pa–€a ¿@n€a@Êω†aÏæa k‰vnÌ Ú€by ¿@fiÎá€a »i@ozjñc Î ÙãÇc á»i@Ú‰@ÜaÜ Ì ›Ó€bzn€a@Üá«@Ÿ–„a bfl ZÚÓÎœ pbfl˝« « szj€a J ›Ác Úöäb»fl Âfl@·Àã€bi ÚÌäÎãö Àa@Î ÚƒÁbj€a ›Ó€bzn€a@»i Úœbög päã” sÓy ÚÓ‘Ó‘y bÌnÁ ëÎœ Î Újnÿæa Ú«b‰æa Êaá‘œ Î@x Î l ájÿ€a lbËn€˝€ ÚÓÎœ@pbfl˝«ZbˉÓi Âfl ã◊â„ NôbónǸa . ﻭ ﻋﻼﻣﺎﺕ ﺍﻟﺰﻫﺮﻱ ﻭ ﺣﻤﻰ ﺍﻟﻤﺴﺘﻨﻘﻌﺎﺕ ﻭ ﻏﻴﺮﻫﺎ2@1K p ÚÌÏ–‡‹€a bÌ˝©a Òœ Û‘jm aâÁ Âfl ·Àã€bi Î Âÿ€ Î Ú‘ˆb–€a@bËmbÓby sÓy Âfl@aj◊ bflá‘m Ú‹‡»næa pbÓ‰‘n€a páËí b‡◊ ÚÓ„bÿflg ‚ÏÌ Î »æa ëΖ€a Û‹« næa@fiÏóy ‚ÏÌ ›ó–m €a Î ÚÓuÏ€ÏÓj€a Òâœb‰€bi Û‡m Òó”@ÚÓ‰flå Ú”Ü@Î Úqaáy ãr◊˛a ÚÓ‰Óßa@÷ã€a@fib‡»na Âfl fiÎá€a »i …œÜ â€a@ıÔì€a@Ÿ€â€ ÚÓuÏ€ÏÓi pbfl˝« äÏË√ NÚõÁbj€a bÁäb»c Âfl ·Àã€bi @Âfl ÚÌb”Ï€a ¿@⁄˝Ën¸a@áÓíãm ÚÓ‡Ác Û‰„ Êc k∞ ¸ Zڀϑ‰æa aãfl˛a Âfl ÚÌb”Ï‹€ ÙãÇc ÷ã†@J Î Âfl˚æa bflå˝j€a ›rfl ‚á€a pbuãÉnfl »i ãÌÏm ‚á€a ›‘„ ◊aãfl Û‹« μ»nÌ b‡◊ Nڀϑ‰æa aãfl˛a ‚á€a ›‘„ ãÌÏm ›r∫ Dza ¿ Î Nnæa –„ ቫ Âfl lÏzæa ㇮a pbÌãÿ€a@ÙÏ‘∑ ¡jmãæa bflå˝j€a Nڀϑ‰æa aãfl˛a Âfl@Îc ÚÓ«b‰fl o„b◊ ıaÏ Ô‘‹næa Úfl˝ ·«á€ Ú»ub„ Ú‹ÓÎ Ômaâ€a UÓÖ|^ k]¡]ïŸ flŸ ÏÁ]ÕÊ’\ 3 Úӫβa ›ÇaÜ ›ˆaÏ€a ·vy ÜbÌÜåa Î paÓ€a Ÿ€â◊ Î Ìãæa ቫ ‚ÏÓbmÏj€a ·◊aãm Üb–m Û‹« ›‡»€a@μ»nÌ NÚÌb”Ï€a ÷ㆠbjmg Î Íbjn„¸a Üãv∑ bËÌÜb–m Âÿ∫ €a Î Ò©a pb–«bõæa Âfl bÁÀÎ UÏ≤]£\ Âfl la”¸a Âfl b‰ÿ∏ ÚÌb”Ï€a ›ˆbÎ ›◊ Âfl ·Àã€bi Î Âÿ€ Î ÒáÌá« p¸by ¿ ÚÌäÎãö ‚á€a ›‘„ pbÓ‹‡« Û‘jm @%.100 Ú–ói bËÓ€g fiÏñÏ€a ÊÎÜ Âÿ€ Î Úfl˝€a Ìãæa ¸g ‘± ¸ Ûny ⁄˝Ën¸a áÓíãm k∞ b‰måÏy ¿ ÒÜÏuÏæa ÚÌb”Ï€a ›ˆbÎ fib‡»na ∂g Úœböbi@Î a†NŸ€à ∂g Úbfl Úuby ¿ ÏÁ@â€a 52 THE ABSTRACTS Section II: Poster Session 7th Magharebian Congress of Hematology (MCH-7) 21st to 23rd May 2010, Zawia Jewel Hotel, Libya PO-01 CLINICAL ANALYSIS, OF MALIGNANT NON HODGKIN’S LYMPHOMA OF THE ORBITAL REGION: 02 CASES A.Salmi and PRN Mesli Hematologie clinical hospital Tlemcen Algeria Purpose: Diagnostic and therapeutic management about two cases of malignant non-Hodgkin’s lymphoma of the orbital region. Patients and method: We report the cases of two patients referred for acute or chronic loss of visual acuity. The first patient has consult for a tumor of the left eye and dacryoadenite. The second patient has consult for the same symptoms and exopthalmous associated with a ptosis. All of them suffered from uveitis or scleritis resistant to corticoid treatment. Search for an infections or immune malignant disease was negative. Results: Diagnosis of high grad malignant non-Hodgkin s lymphoma centroblastique in the first and low grad lymphoplasmocytaire in the second was assessed after biopsy of the tumor orbital.the immunohistochemical analysis is not available. The two patients underwent chemotherapy associated with chirurgical for one patient. The lesion were stable in one case but the acuite visual has disappear Discussion: The diagnosis of malignant non-Hodgkin s lymphoma of the orbital must be assessed by an early biopsy and immunoistochemical analysis. Then a specific treatment must be instituted to limit the loss of the vision. All cases of chronic and cornea resistant uveitis require a specialised radiological evaluation followed if necessary by multiples orbital biopsies 55 PO-02 SPLENIC LYMPHOMAS: A REPORT OF 18 CASES S. Hamdi; M. Dali; FZ.Benkhodja; A. Amoura; N. Zatout; F. Z.Nasri. Department of Hematology - CHU de Setif – Algeria Introduction: If the spleen secondary damage is very common in lymphomas, the primary achievement is rare (0.5 to 2%). The primitive splenic lymphomas are characterized by the presence of splenomegaly without lymphadenopathy surface, possibly associated with bone marrow infiltration. The imunophénotypage allows for the differential diagnosis between lymphoid proliferations. We report 18 cases of splenic lymphoma followed between 1998-2009. Patients and methods: This is a retrospective study comprising 10 men and 8 women, mean age was 57 years (21-71 years). The diagnosis is established after a splenectomy (6cas) and after biopsy (12cas). Immunophenotyping was performed in 8 patients. The staging is done according to the terms of nodal NHL. The protocols used: CHOP (n = 9), 3 with rituximab, COP (n = 2), CF (n = 1), endoxan (n = 3), three patients were not treated. Results: The histology shows: lymphocytic and lymphoplasmacytic lymphoma (6 cases), marginal zone lymphoma (5 cases), diffuse small cell Centrocytic lymphoma (1case) and large cell lymphoma (6cases) including 2 cases of phenotype T. Circumstances of discovery: splenomegaly: 100% of cases. PS0-1: 67%. LDH in 50% normal, bone marrow affected in 83% of cases. Therapeutic results in 16 evaluable patients: RC: 8cas (50%), PR: 4 (25%), Failed: 4 (25%) deaths: 5 (31%) relapsed: 3 (37%). Overall survival (OS) and Disease free survival (DFS) respectively 70% and 50% at 7 years. Conclusion: The primitive splenic lymphomas are rare and have the distinction of being associated with bone marrow. Splenic lymphomas are generally indolent and According to the WHO classification, the entity lymphoma marginal zone is the most common. The therapeutic results are within the range of published series. Splenectomy combined with chemotherapy is the treatment of choice. 56 PO-03 LYMPHOME DIFFUS A GRANDES CELLULES B À LOCALISATIONS MULTIVISCERALE A PROPOS D’UNE OBSERVATION F. Fergane, K. Benallaoua, H. Laga, W. Chaba, S. Dechir, R. Drif, N. Dali, O. Ouanes, K. Ait Seddik, M. Alllouda, S. Gherras, H. Aftisse, A. Graine, Et Pr. H. Ait Ali Service d’Hématologie CHU de TIZI- OUZOU Introduction: Les lymphomes diffus à grandes cellules B sont la variété la plus fréquente des lymphomes non Hodgkiniens (LNH), ils représentent un tiers de l’ensemble des lymphomes. Cependant les localisations multiviscérale restent rares.Nous rapportons l’observation d’un patient atteint d’un LNH B à localisations multiviscérale, révélé par une atteinte cérébrale et associant des localisations cutanée, pulmonaire, rénale et mésentérique. Observation: IL s’agit d’un patient âgé de 44 ans, sans ATCD pathologiques, admis le 04/10/2008 pour prise en charge d’un LNH à grandes cellules B. Le début remonte à Février 2008 par une hémiparésie droite avec à l’ IRM cérébrale de multiples lésions nodulaires de la substance blanche pariéto-insulaire gauche, une origine tuberculeuse à été évoquée (IDR à la tuberculine 15 mm), donc il a été mis sous anti- tuberculeux mais sans résultats. Six mois après, le patient présente des nodules cutanés et des ADP inguinales. L’étude histologique de biopsies ganglionnaire et d’un nodule cutané est revenue en faveur d’un LNH à grandes cellules B, CD 20 positif. L’examen à l’admission: patient en état général conservé, présentant des signes généraux (sueurs nocturne, amaigrissement), ADP axillaires et inguinales bilatérales, hémiparésie droite avec dysarthrie, Bilan d’ extension: TLT: ADP médiastinales (IMT: 0, 34), TDM thoracique: ADP médiastinales, et nodules pulmonaires bilatéraux,TDM Abdominale: reins globuleux siège de multiples formations nodulaires, des nodules mésentériques ainsi que des ADP intra et rétro- péritonéales.Le bilan hépatique et la biopsie médullaire sont sans anomalie. Il s’agit donc d’un LNH à grandes cellules B CD20 positif stade IV B (classification d’ Ann Arbor) avec localisations multiviscérale (cérébrale, cutanée, pulmonaire, rénale et mésentérique). Décision thérapeutique: 08 cures R- CHOP associées à une chimiothérapie intra-thécale (06 inj). Le patient est vivant, en rémission complète depuis 13mois, mais ayant gardé une démarche 57 en fauchant du membre inférieur droit ainsi qu’une main en griffe, séquelles de la localisation cérébrale. Conclusion: l’atteinte multiviscérale au cours des LNH à grandes cellules reste rare, la localisation et le pronostic souvent réservé, mais une rémission complète avec une chimiothérapie de première ligne reste possible, c’est le cas chez notre patient. 58 PO-04 MEDIASTINAL LARGE B-CELL LYMPHOMA A CLINICOPATHOLOGIC REVIEW OF 17 CASES S. Hamdi; FZ.Touil; A.Achichi; Z.Bouhadda; S. Lekhel; Z. Nasri. Department of Hematology - CHU Setif - Algeria Introduction: The primitive lymphoma of the mediastinal (LPM) is rare, they account for 6-10% of all nonHodgkin lymphomas and their histological type varies by age. In adults, lymphoma diffuse large B cell sclerosis is an anatomo-clinical entity now well defined and their frequency is 2.4% of all lymphomas, located in the anteroposterior region of the mediastinal, they come from B cells the thymic medulla. We report 17 cases followed between 2000 and July 2009. Patients and methods: The diagnosis is made following a pleural biopsy in 7 cases, transparietal biopsy in 10 cases. The histological type is diffuse large B-cells in all patients. Immunophenotyping done in 10 subjects reveal a tumor population expressing CD20, CD79a + and CD 23 expressing neither EMA nor CD30. Results: Age below 40 years for 13 patients (76%), the average age is 31 years. There are 13 women and 4 men. The circumstances of discovery are represented by chest pain associated with cough in 53% and a superior vena cava in 35%. The prognostic factors are present in 2 / 3 of patients about (LDH> normal in 70%, Bulky mediastinal mass > 10 cm in 71%). The extra nodal sites are contiguous with the lung (29%), pericardium (24%) and pleura (35%). Other visceral are the bone marrow (6%) and liver (6%). Protocols used: COP / BLAM III: 8 cases - C2H2OPA: 8cases + rituximab: 4cases and RCHOP: 1cases. Follow-up:7 – 54 months. Results: complete response (CR): 59%, Partial response (PR): 18%, failure: 23%, relapse: 30%. We record 9 deaths (53%). Overall survival (OS) and disease free survival (DFS) respectively 45% and 30% at 5 years Comments and conclusions: The primitive lymphoma of the mediastinal with large B cells respond well to a particular entity. Indeed, the differences compared to other aggressive nodal lymphomas are: female, median age 30 years, the tumor bulky (> 7cm) with involvement of contiguous sites (pleura, lung and pericardium), the rate LDH often high and the clinical stage usually localized. The rate of complete response is a share in the range of series reported in the literature and secondly, it has improved since the introduction of rituximab and the intensification of CHOP, however, the series is limited and the short period. Moreover, optimization of improvement lies in the practice of intensified consolidation therapy followed by autologous stem cells. 59 PO-05 THE PRIMITIVE GYNECOLOGICAL LYMPHOMAS: A REPORT OF 3 CASES S. Hamdi; I. Bentahar; N. Belahdaia; N.Zatout. Department of Hematology - CHU de Setif - Algeria Introduction: The gynecologic organ involvement by non-Hodgkin lymphoma is rare (less than 1%). We report two cases of ovarian lymphoma and one case in the cervix. 1st observation: Girl 25 years old, single, PS: 2. Consults for abdominopelvic mass accompanied by pain without lymphadenopathy. A laparotomy with oophorectomy left + right oophorectomy were performed. The histological study objective NHL diffuse small cell ovarian localization. Staging allows to classify the disease stage IV according to Ann-Arbor’s classification (liver). 2nd observation: Woman 36ans, mother 2enfants, PS 2, has abdominal pain without pelvic lymph nodes, the scanner showed a tumor of ovarian 75/57mm. Histology: NHL diffuse large cell B. Staging allows to classify the disease stage I according to Ann- Arbor. It received 5 courses of CHOP, after complete remission, she is put under rituximab maintenance. She is alive at 25 months. 3rd observation Female 48 years old, mother of 09 children. PS: 1; this pelvic pain, ultrasound objective abdominopelvic solid mass in the vagina de7/6cm. The scan shows a pelvic mass occupying the lower cervical region. The biopsy of the tumor to objectively review the pathological the NHL diffuse large cell. The staging allows the patient to classify the stage IE. She received 6 courses of CHOP but lost sight in 6months. Comments- conclusions: The primitive sites (ovaries and cervix) without lymphadenopathy confirm the location as extranodal. The existence of primary ovarian lymphoma is now recognized by highlighting different study by the presence of aggregates of lymphoid cells in normal ovarian parenchyma, and the existence of long-term survivors in complete remission after treatment. That of cervical lymphoma is even rarer because sixty cases were reported in the literature. 60 PO-06 ABOUT A CASE OF NON-HODGKIN LYMPHOMA OF HIGH GRADE MALIGNANCY N. Hout; , Mesli N. Department of Clinical Hematology - University Hospital Tlemcen, Algeria. Introduction: The non-Hodgkin lymphoma represents a group of lymphoproliferative disorders, characterized by their heterogeneous clinical, histological, therapeutic and prognostic, results of infiltration (nodal and extra nodal) by malignant lymphoid cells from either line B or T. Goal The purpose of this presentation is to present a real therapeutic problem facing a case of nonHodgkin lymphoma initially chemo sensitive node in a immunocompetent man who later relapsed with cutaneous localization highly chemo-resistant Comment: We report a case of non-Hodgkin lymphoma of high grade malignancy diagnosed in 2006 in a patient aged 27, male, immunocompetent diagnosis by pathologic study of lymph node biopsy, which revealed the nature of the anaplastic lymphoma tumor proliferation suggestive of NHL of high grade malignancy. In staging the patient was classified stage III A. Therapeutically the patient received CHOP chemotherapy was the second course, loss of peripheral tumor syndrome. After six months of treatment (08 treatments), the patient returned to full remission. We undertook a quarterly monitoring clinical and laboratory until the end of 2009 the patient presented a resumption of tumor syndrome associated with superficial and deep to a secondary location said diagnostic skin biopsy of the skin lesion which immunostaining said the phenotype of T malignant proliferation. The patient received two treatments MBACOD but due to the disruption of the renal doses were adjusted according to creatinine clearance ; two DHAP courses and one EPOCH courses. After each course we noticed a tumor regression syndrome as well as the size of the training skin but short with relapse in inter cure made a resumption of tumor syndrome and a widening of the training skin associated with the development of a new headquarters location of secondary bladder. Discussion: * CHOP chemotherapy given in remission forms favorable; but the risk of relapse after discontinuation is inevitable. * Installing a secondary cutaneous localization and bladder chemoresistance compromises the 61 prognosis * The introduction of multiple chemotherapy exposes my patient at important hematologic and renal toxicity. * It is treated within the protocols of the nodal primitive or adds to the treatment indicated in cases of secondary locations including skin. * Chemoresistance to different protocols introduced us to face a therapeutic impasse. Conclusion: The natural history of NHL remains burdened extended relapse less sensitive to chemotherapy practitioners posing a real problem of therapeutic management compromising the prognosis and quality of life of patients. 62 PO-07 THE NON HODGKIN’S LYMPHOMAS OF ADULT IN THE NORTH–EAST OF ALGERIA: ANATOMO–CLINICAL STUDY Mehennaoui-Toumi H.1, Lankar A.2, Boughrira S.1, Grifi F.1 (1) Heamatology Service, Dr. Dorban Hospital, C.H.U. Annaba (Algeria) (2) Pathological Anatomy Service, Ibn Rochd Hospital, C.H.U. Annaba (Algeria) The non-Hodgkin’s lymphomas are lymphoid malignancy, derived from lines B or T. Their incidence has increased dramatically in the past decades. Our study is descriptive and is 7 years long, from January 2000 up to December 2004, for retrospective study, and from Junuary 2005 up to December 2006, for the prospective study. It has interested 111 patients who present a lymphoma of the lymph node. The median age is 52 years (range 16 - 96 years). The ratio-sex (M/F) is equal to 1,85. The diagnostic mean deadline is 4,5 months. The clinical array is dominated by the adenopathies. The most frequent associated extra nodal localisations are: oral, pleuropulmonar and digestive. The anatomo-pathologic diagnostic has revealed a net predominance of the aggressive lymphomas (75%). The immunohistochemical study carried over 37 patients has allowed to state that the frequency of type B is 89%. The extension bilan shows that 63% of the patients are on the extended stages of the sickness (III and IV). The appreciated prognostic, from I.P.I. point of view, for the aggressive lymphomas reveals a rate of 70% of patients of pejorative risk (high and high intermediate) and the predominance of cases of big tumor mass for the indolent lymphomas. The most used protocole is the CHOP. Because of immunohistochemistry, patients have been treated by monoclonal antibody (anti-CD 20). The ratio of global reaction observed on patients who present aggressive lymphomas following a retrospective study is 64,1 % whereas in the prospective study it is 78,2 %. In the case of indolent lymphomas, the complete reaction is observed on 63 % of patients treated in the retrospective study and is 83 % on patients from the prospective group. The median steady period of the aggressive lymphomas is 20,2 months (range 1 - 73 months). The median time up to progression for the indolent lymphomas is 31,6 months. 63 PO-08 LYMPHOMES OSSEUX B PRIMITIF A LOCALISATION DIFFUSE A PROPOS D’UN CAS N. Dali1, M. Allouda1, K. Ait-Seddik1, O. Ouanes1, S. Gherras1, H. Aftisse1, Et H. Ait-Ali1, M. DJENANE2 1 Service d’Hématologie, CHU DE TIZI-OUZOU. 2 Service de Rhumatologie, CHU DE TIZI-OUZOU. Introduction: Des lymphomes osseux primitifs (LOP) représentent 1% de l’ensemble des lymphomes, 5% des présentations extranodales et 07% de l’ensemble des tumeurs osseuses malignes. Le mode de révélation clinique est celui de toute tumeur osseuse: douleurs, fracture. Les os longs sont plus souvent concernés que le squelette axial. Les LOP se présentent comme une lésion unique, localisée. Le phénotype B est le plus souvent rencontré. Nous rapportons l’observation d’un patient atteint d’un LNH B à localisations osseuses diffuses exceptionnelles. Observation: Il s’agit d’un homme de 65 ans, sans antécédents notables, qui présente depuis 02 mois des douleurs osseuses avec conservation de l’état général. L’examen clinique retrouve une tuméfaction siégeant au niveau de la clavicule droite, fixe, sans signes inflammatoires en regard. Par ailleurs absence de syndrome tumoral périphérique et profond. La radiographie des membres supérieurs, inférieurs, crâne et thoracique a objectivé un processus lésionnel tumoral ostéolytique très important (tibia péroné - carpes – métacarpes- humérus, cubitus, radius, tarses, métatarses, fracture de la clavicule, crâne) faisant évoquer un diagnostic de métastases osseuses ou maladie de paget. Le bilan d’extension initial était strictement normal confirmant le caractère primitif. L’histologie de la biopsie claviculaire conclue à un plasmocytome mais le bilan d’un myélome multiple était négatif. Médullogramme, électrophorèse des protéines, protéinurie de 24h, bilan phosphocalcique normaux. En quelques mois, l’état général du malade s’est dégradé rapidement, avec apparition de lésions cutanées multiples de 4 à 5 cm de diamètre de siège diverses (cuir chevelu, front, face interne des 02 jambes et coudes). La 2ème TDM thoraco-abdomino-pélvienne retrouve des nodules pulmonaires du lobe supérieur gauche et des adénopathies iliaques. Sur le plan biologique, on a noté une hypercalcémie maligne à 200 mg/l nécessitant une réanimation et un traitement par biphosphonate. L’histologie de la biopsie cutanée et l’immunohistochimie de la biopsie claviculaire concluent à un LNH de haut grade de malignité de phénotype B. Ce diagnostique a été confirmé par le groupe d’études Algérien des lymphomes (GEAL). Le patient a bénéficié d’une chimiothérapie: 03 cures de (R-CHOP) avec une réponse favorable à 60 %, mais malheureusement il a présenté une toxicité cardiaque. Les traitements de 64 relais étaient sans succès avec apparition d’autres localisations notamment cérébrales et ophtalmiques. Le malade est vivant en échec thérapeutique. Conclusion: Notre observation est exceptionnelle par la localisation osseuse diffuse, mais ayant les mêmes particularités para cliniques et histologiques que celles rencontrées dans la littérature. 65 PO-09 RESULTS ABVD PROTOCOL IN THE TREATMENT OF HODGKIN LYMPHOMA IN ADULTS M.

Service de Radiologie, Hôpital 20 Août 1953 ; CHU Ibn Rochd, Casablanca, Maroc Introduction: The ABVD protocol is a gold standard treatment for Hodgkin lymphoma (HL). In this study, we present the results of prospective study, spanning the period from March 2007 to March 2009, our aim objectives are to analyze the efficacy of this combination in the treatment of patients with HL. Methods: The HL has been confirmed, according to the WHO classification, the stages were identified after a staging systematic: clinical examination, ESR Blood Chemistry, CBC, bone marrow biopsy, chest radiograph and CT scan. The chemotherapy program was ABVD (doxorubicin, bleomycin, vinblastine and Dacrabazine). The number of cycles was determined by prognostic groups (EORTC prognostic), Patients with early stages (favorable group received 4 cycles and 6 cycles for the unfavorable group) followed by radiotherapy IF; patients with advanced stage received 8 cycles, only those with bulky tumor received radiotherapy. Results: During 2 years, 94 cases were included, the mean age was 35 years [17-60], more men (63%) than women (37%). the nodular sclerosis subtype was predominant (62.8%). Bulky tumor mass was present in 36 cases. 40 patients were early stage (44.5%), only 4 of them had a favorable prognosis. Advanced stages represent 55.5% with a high score (IPSS> 2) in 46 cases. In The early stage group, the complete remission was obtained in 34 patients (85%), 6 patients field to achieve CR, only one of them achieved CR after intensification, any case of relapse was noted. Thirty eight patients among advanced stage group achieved CR (70,4%), the failure was observed in 9 cases; 6 patients lost during treatment, the relapse was noted in 4 cases, 7 patients died in failure or after relapse. The Overall survival at 36 months was 100% for the early stage group and 78% in advanced stage group; the event free survival was 85% in the early stage group and 64,3% advanced stage group. Conclusion: The results obtained with the ABVD protocol in our study were correlated with clinical stages and join those in the literature. However, the problem of patients lost to follow-up make difficult a proper interpretation of these results. 66 PO-10 MEDIASTINAL LARGE B CELL LYMPHOMA ABOUT 12 CASES F. Belhadri, H. Moussaoui, F. Boukhemia, N. Abdennebi, S. Belattaf L. Kouici, D. Benali, S. Zeghouati, N. Boudjerra, RMH. Hamladji. Department of Haematology and Bone Marrow Transplantation; Pierre and Marie Curie center, Algiers, Algeria Introduction: The mediastinal large B cell lymphoma is a recent individualized entity, described the first time in 80’s.It develops from B cells of the thymus medulla with distinctive clinical, histological, immunohistochemistrical and genetic features. It represents 2.4% of non-Hodgkin lymphoma and 5% of large B cell lymphoma. Material and methods From September 2006 to September 2009, 12 cases of large B cell lymphoma of the mediastinum were diagnosed. 5 patients were treated according to protocol R-CHOP (Rituximab 375mg / m2 day 1, Adriamycin 50 mg/ m2 day 1, cyclophosphamide 750 mg/ m2 d1, Oncovin 1.4 mg / m2 d1 and Prédnissone 40mg/ m2 of d1-d5) at the rate of a cure every 21 days and 6 patients were treated according to Protocol RC2H2OPA (Rituximab 375mg/ m2 IV in d1,, Cyclophosphamide 1.5 g/ m2 IV d2, Adriamycin 90 mg/ m2 IV d1, Oncovin 1.4 mg / m2 IV d1, Ara-C 100mg / m2 d1 to d3 in subcutaneous, Prednisone 80mg / m2 d1 to d5 or SLM 100 mg/ m2), at the rate of a cure every 21 days. Results The median age of 12 patients (pts) is 27 years (17 to 37 y) and sex ratio (M / F) 1. Clinically, the reason for consultation is dominated by the functional respiratory signs, present with 5 pts (42%), the superior vena cava syndrome with 4 pts (33%) and chest pain with 3 pts (25%), 8 pts (67%) had ECOG 1 and 4 pts ECOG 2 (33%), the general signs found with 4 pts (33%) and in physical examination 10 pts (83%) had a superior vena cava syndrome. The diagnosis was established by histology after image-guided percutaneous needle aspiration biopsy of the mediastinum for 08 pts (67%) and after thoracotomy for 4 pts (33%), it was mediastinal large B cell NHL for 04 pts (33 %), thymoma for 06 pts (50%), Hodgkin’s disease or thymoma for 01 pt and Hodgkin’s disease for 01 pt. The average diagnostic delay of 03 months (o1-11), a bulky mediastinum was noted in all patients with MTI (mid-thoracic index) through 0.45 (0, 30 -0.68), two pleural effusions, two pericardial effusions and jugular vein thrombosis in 6 pts (85%) for 7 Doppler ultrasound done. Therapeutically, 4 pts received 8 cycles of R-CHOP, one patient received 5 courses with 2 incomplete remissions (RIC) and 3 fails, one patient received radiation, not made for the other 67 patients because of the evolutive disease, intensification with autologous made for one patient. One patient is alive and in CR with a survival of 11 months, four (4) died with median survival 16 months (14 to 30). Six (6) pts were treated according to Protocol RC2H2OPA with one complete remission and 5 incomplete remissions. Six (6) pts received radiation therapy, one patient underwent an intensification with autologous bone marrow transplantation. One patient died at 15 months, five (5) pts are alive with a median survival of 10 months (7-19). One patient was treated according to protocol RDHAP (for patient already treated with max doses of anthracyclines), in the end the treatment failed (died). For the protocol RCHOP good tolerance was observed in all pts, for protocol RC2H2OPA cytopenia after the first course was observed with two pts, whose nadir (GB 200: mm3, HB 8.9 g / dl, PLQ 54,000 / mm3) Conclusion The Mediastinal large B cell lymphoma is a pathology of young patient. Superior vena cava syndrome is predominant, the tumor is large. A diagnosis problem with thymoma and Hodgkin’s disease, where the interests of the immuno histochemistry. R-CHOP is ineffective in our series. The RC2H2OPA is better than R-CHOP but now the decline is insufficient.These results require us to be careful in the diagnosis and to adapt a therapeutic strategy to improve the overall survival of these young patients. 68 PO-11 ACTIVITY OF ALGERIAN STUDY GROUP ALGERIAN OF LYMPHOMA (GEAL): SUB GROUP OF PATHOLOGY OF MIDDLE CENTER K.

They encompass an extremely heterogeneous group of diseases ; the heterogeneity is based on the multiplicity of histology sub types, clinical presentations)nodal and /or extra nodal), tumor behavior)localized vs disseminated), and the presence /absence of concomitant disease impacting treatment option. For this reasons the Algerian Study Group of Lymphomas)GEAL) created on the 26th. A sub group created to deal with the pathologist of the Middle centre. Materiel and methods: Diagnosis of lymphoma always require biopsy or resection followed by full pathologic analysis including cytology and immunology. CD 20 and CD3 antigen positive tissue indicates either B or T cell lymphoma. In all difficult cases, the diagnostic must be confirmed by more pathologists specializing in the diagnosis of lymphoproliférative disorders. From February 2007 to Mars 2010, 237 difficult cases of lymphomas (nodal and / or extra nodal) were analyzed by the sub group of pathology. Results: The nodal Lymphomas are predominant (65%), the Diffuse Large B Cell Lymphoma (DLCL) accounts 47.5 % of all lymphomas, the median age was 45 years. The initial diagnostic histology is confirmed in 70 %. Conclusion: The diagnosis of lymphoma require a good biopsy, and analysis including cytology and immunology. The confirmation by more pathologists is very important in the difficult cases. 69 PO-12 PRIMARY NON HODGKIN’S LYMPHOMA OF THE ADRENAL GLAND: CASE REPORT AND REVIEW OF THE LITERATURE Semoud.I -Djennouni.A-Bencheikh.N-Boughrira.S -Grifi.F Service of Hematology, CHU Annaba, Algeria. Introduction: The primary lymphoma of the adrenal gland is very rare, less than 100 cases have been reported in the literature. Comment: We report the case of a patient aged 52 years admitted to: General symptoms: fever, asthenia,weight loss and lumbar pain. Abdominal CT scan objective left adrenal mass. The diagnosis of B cell lymphoma of the adrenal gland was made after immunohistochemical study of the surgical resection piece. The staging did not show any other lymph node or visceral location and concluded to primitive NHL. The patient subsequently developed thrombosis of the inferior vena cava with pleural effusion. She received chemotherapy R / CHOP with symptomatic treatment. After 6 cycles, the results are favorable with a retroperitoneal fibrosis. After 12 months of follow-up, the patient is always in remission. Conclusion: The adrenal gland lymphoma is rare and should be considered in any adrenal mass to avoid the use of aggressive surgical exploration. 70 PO-13 DIAGNOSIS OF LYMPHOPROLIFERATIVE DISEASES BY FLOW CYTOMETRY (FCM) S. Taoussi, S. Oukid; M.T. Abad Department of Hematology, EHS CAC, Blida, Algeria Background: The approach to the classification of hematologic neoplasms by FCM gives us the large amounts of valuable information to define and specify the monoclonality of these tumors. Flow cytometry (FCM) is on use consistently in our laboratory in complement to cytology and histology. Materials and methods: We report the results of 149 patients that have chronic lymphocytosis evaluated by flow cytometry in the hematology department EHS CAC, Blida. The methods are based on clinical examination, a cytological study and immunophenotyping performed on a blood sample in 149 patients and a bone marrow sampling in 02 patients; In the first approach, the samples are analyzed with a large panel of monoclonal anti bodies. The number of antibodies in the panel is sufficiently extensive to permit a full characterization of lymphoid proliferations of B, T and NK cells.In the second approach, the FCM study starts with a limited and selected panel.The results are based on using the Matutes score and the percentage and intensity of positive cells. Results: CLL: 94 patients with a Matutes score: 3 / 5: 03 Pts, 4 / 5: 44 pts and 5 / 5: 47 pts. Mantle NHL: 20 pts. Villous NHL: 09 pts. Follicular NHL: 08 pts. NHL of marginal zone: 06 pts Prolymphocytic leukemia: 01 T leukaemic NHL: 01 pts. Undefined NHL: 05 pts. Hairy cell leukemia: 04 pts. Normal: 01 pt 71 Comments: FCM has proven to be extremely helpful in diagnosing and classifying mature B-cell neoplasms.In our population, FCM specified the nature of lymphomatous monoclonal populations in most patients. Correlation among the FCM data, lymphocyte count, blood, marrow or lymph node smear morphology, and clinical findings is therefore often necessary. Immunophenotyping by flow cytometry should be a routine method for diagnosis when lymphoproliferative disease is suspected. 72 PO-14 COMPOSITE LYMPHOMAS ABOUT ONE CASE Menad.A,Bensmaine. m.a, Yachekour.

In the majority of the cases in the literature, it is about the association of hodgkinien lymphoma and no hodgkinien lymphoma. We report a case of them. In our presentation: bringing back a case of association: multiple myeloma with a diffuse large B- cell lymphoma (DLBCL). Patients and methods: H B.A age 69 years old in September 2009 the diagnosis of a multiple myeloma with IgA λ stage III B and diffuse large B- cell lymphoma (DLBCL) stage VI,medullary and hepatic,diagnoses posed on a Lymphnod biopsy and osteomédullary biopsy, treated by protocol VAD after 3 courses à RP 50% for the NHL we started protocol CHOP after 06 COURSES a RCU of the lymphoma was obtained then one took again the treatment of the myeloma protocol VMCP, after 10 of chemotherapy course Conclusion: The composite lymphomas pose a problem of diagnosis and therapeutic and which does not appear in classification WHO 2008. 73 PO-15 CHARACTERISTIC OF NON HODGKIN’S LYMPHOMA IN ALGERIA ABOUT FOUR YEARS: 2006 – 2009 N Boudjerra Algerian Study Group of Lymphoma (GEAL) Introduction: Non Hodgkin’s Lymphoma (NHL) is composed of a group of lymphoid malignancies that has been increasing in incidence at an annual rate of 4 % to 7%, over the last 20 years in both United States and Europe, this analyses suggest that it is also the case in developing countries. Methods: 1100 patients were studied about four years (2006 – 2009), eleven centers of hematology in Algeria participated for this study. Results: We observe increase of lymphoma , the number of diagnosed cases was 186 in 1998 and 342 in 2008. The World Health Organization (WHO) classification was utilized by all, the Diffuse Large B cell Lymphoma (DLCL) account 47.5 %, the mean age of patients was 48 years, sex ratio M/ F: 1.40. Consensus therapeutic was adopted since 2007: CHOP or R CHOP (indolent or aggressive lymphoma), C2H2OPA (Mediastinal lymphoma), COPADEM (burkitt’s lymphoma), Linker (lymphoblastic lymphoma). Conclusion: Lymphomas are group of cancers that share a common cell of origin and a particular mode of development. They consist of numerous subgroups, some of which can be cured with conventional therapy, while others more intensive treatments. 74 PO-16 T-NK LYMPHOMAS OF NASAL TYPE: CLINICAL ANATOMY STUDY OF SEVEN CASES Mehennaoui-Toumi H., Bencheikh N., Boughrira S., Grifi F. Heamatology Service, Dr. Dorban Hospital, C.H.U. Annaba (Algeria) Introduction: The T-NK lymphomas of nasal type represent a rare but aggressive form of malign lymphatic proliferations. We report through our experiment of taking in charge 7 patients, the clinical, the anatomopathologic and the evolutive characteristics of this pathology. Materials and methods: The medical files of 7 patients (4 women and 3 men) have been studied for the years from 2003 to 2009. Results: The average age of our patients is 45,7 years where the extrema are 19 and 74 years. The clinical table associates the ORL manifestations of type dysphonia, nasal obstruction, epistaxis, disphagia, hypacousia. In most cases, the sickness is localised (IE, IIE), the IPI is less than or equal to 2 in all cases. The anatomo-pathologic study confirms the tumoral proliferation made of positive big cells with the 45CD and the 3CD. The therapeutic choice is directed toward the L-Asparaginase-Dexamethasone Velbé association to 4 patients and the response is good for 2 cases. The patients who are initially treated by CHOP have rapidly relapsed. In the terms of our study, 5 patients are alive: 2 in complete relapse after one chemotherapeutic line and 3 after the second and third chemotherapeutic line. Two patients have died. The average survival is of 27 months (2-69). Conclusion: The T-NK lymphomas of nasal type are a form of lymphatic proliferations with a poor prognosis. The presentation is often localised. The CHOP protocole seems inefficient in this pathology. The association including the L Asparaginase is efficace but is not exempt of relapses 75 PO-17 ASCT IN HODGKIN AND NON HODGKIN LYMPHOMA: A SINGLE CENTER EXPERIENCE ABOUT 27 PATIENTS Bach Hamba S, Ben Amor R, Ben lakhal R, Jeddi R, Aissaoui L, Kacem K, Bouteraa W, Abdennebi Y, Ben Abid H, Bel Hadj Z, Balkis M. Aziza Othmana Hospital, Tunis. Introduction: Autologous hematopoietic stem-cell transplantation (ASCT) is an effective treatment for recurrent or refractory Hodgkin lymphoma (HL) and for advanced or refractory Non Hodgkin Lymphoma (NHL). In this study, we retrospectively evaluate results and outcome of patients with HL and NHL benefiting of ASCT in Aziza Othmana Hospital. Patients and Methods: We collect data from 27 patients who received ASCT between July 07 and December 09. The conditioning regimen consisted of carmustine, etoposide, cytarabin and melphalan (BEAM). 14 patients had HL and 13 patients had NHL (Diffuse Large B-cell Lymphoma n = 8, Mantle cell Lymphoma n = 2, Anaplasic Cell Lymphoma n = 2, Follicular Lymphoma n= 1). All patients with HL had a recurrent or refractory disease. Concerning NHL, ASCT was performed as conventional consolidation treatment for advanced forms in complete remission (CR) in 8 cases and as salvage therapy for refractory patients in 5 cases. At time of ASCT, the patients were: in CR (n = 22), PR (n = 3) and in progressive disease (n = 2). The median age was 32 years (18 – 56 years). Sex ratio: 1,25 (15M/12F). The graft consisted of peripheral blood in all patients with a median CD34 cell dose injection of 6,16 x 10.6/Kg (2,6 – 11,3 x 10.6). Patients received GCSF at day 5 post transplant. Results: Median delay of hospitaliza.tion was 17 days (13 – 21 days). The median delay of chemotherapy induced neutropenia was 8 days (5 – 11 days) with fever in all patients. No major complications or toxicity was noted in hospitalization. 6 patients died in the 6 months following ASCT; 5 from progressive disease and 1 from late pulmonary infection. With a median follow up of 18 months (4 – 33 months): 20 patients (74%) were in CR, 3 patients (11%) in PR and 4 patients (18%) were still in stable disease despite progression (two of them benefit of other salvage therapy). The OS at 18 months was 77%. Conclusion: The first experience of ASCT in our center is encouraging. In accordance with previous studies, disease status at transplant was the most important factor of outcome in our patients. In fact 90% of patients transplanted in CR (18/20) were in good response. We need larger patient’s number to proceed to statistics analyzes. 76 PO-18 PRIMARY CEREBRAL LYMPHOMA; A RARE LYMPHOMA LOCALISATION. ABOUT A CASE R. Khelifi Touhami, S. Boughrira, F. Grifi. Department of Hematology, Dorban hospital, Annaba, Algeria Introduction: Primary cerebral lymphomas are malignant non Hodgkin lymphoma developed in the cerebral parenchyma. They represent 2% of extra nodal lymphoma and 5% of primitive brain tumors. Their increased incidence is noted for 20 years, now it is decreasing. No epidemiological factors are known, they are developed most often a condition of congenital immunodeficiency (Wiscott Aldrich syndrome), but mostly acquired (HIV, immunosuppressive therapy). Observation: Patient aged 24 years, without medical history, present since 8 months of intense headaches refracted to usual painkillers. The table was complicated by the installation of seizures with motor weakness located (upper left). The biological and the metabolic assessments were without abnormalities. The radiographic assessment showed a round image localized on para-sagittal right measuring 6 of 5 cm. The patient underwent partial resection of the mass. Histological examination and immunohistochemical study of the specimen was in favor of non Hodgkin lymphoma with large cell phenotype B. After a negative staging, chemotherapy was setup type R-COPADEM associated with intra techal chemotherapy. Clinical and radiological evolutions were good after 2 cycles of treatment. Therapy maintains type CYME is expected with radiotherapy. Conclusion: Primary cerebral lymphoma is relatively rare tumor involving the brain tissue. Potential unfavorable prognostic factors for survival are: age > 60 years, WHO performance status > 2, pre-treatment and neurological function, extensive tumor spread, no administration of chemotherapy, CSF protein level at diagnosis > 0.6 g/l. 77 PO-19 A CASE HODGKIN LYMPHOMA RELAPSE AND PYODERMA GANGRENOSUM M.Benlazar, A.Hadjeb, A.El Mestari, N.Zemri, K.Tayebi, N.Siali, R.Messaoudi, Z.Zouaoui. Hematology unit, Hospital of Sidi Bel Abbés, Algeria. Introduction: Pyoderma gangrenosum (PG) is un uncommon ulcerative cutaneous condition of uncertain etiology. It is classified as a neutrophilic dermatosis, and exhibits intense dermal inflammatory infiltrates composed of neutrophils with little evidence of primary vasculitis. Etiology is believed to represent a manifestation of altered immunologic reaction and it responds to immunosuppressive therapy. Approximately 50% of PG cases are associated with a specific systemic disorder. These include inflammatory bowel disease, rheumatoid arthritis, non Hodgkin lymphomas, chronic myeloproliferative disorders and acute leukemias. Case study: We report the case of 39 years old female patient, treated in April 1996 for Hodgkin lymphoma. The patient was staged IIB and received six cycles of M.O.P.P regimen. She achieved a complete remission and did not accept radiotherapy. Ten years after, in April 2006, the patient came to the dermatologist observation because of an extensive, bilateral and violaceous skin nodules on the anterior sides of the legs. These nodules became wider and reached a diameter of 10 cm on the left leg with much ulceration. We find bilateral cervical and axillary nodes. Total body C.T scan showed a mediastinal involvement.The dermatologist suspected the diagnosis of PG and the histology of the skin confirmed his diagnosis. The biopsy of a left large cervical node confirmed the Hodgkin lymphoma. The patient was staged IIIA according to ANN Arbor Staging System, and therapy was treated with steroids (Prednisone, 100mg/day). On the seventh day of this therapy, a regression of the skin lesion was noted. The Hodgkin lymphoma chemotherapy was started 10 days later, the patient received A.B.V.D without an important regression of the nodes. The skin lesions disappeared and we switched the lymphoma chemotherapy to D.H.A.P. A complete remission was achieved after four cycles of D.H.A.P. The patient did not accept radiotherapy, she is alive and in complete remission. Conclusion: Our case underlines that PG should be included in the differential diagnosis of any nodular and ulcerative cutaneous eruption in patients with Hodgkin lymphoma. It responds to steroids and has not any prognosis impact on the lymphoma. 78 PO-20 ANATOMICAL AND CLINICAL CORRELATION OF LYMPHATIC DRAINAGE PERTAINING TO LYMPHOMA Hassan Mohammad, Mahmoud El Hamidi Department of Anatomy, Faculty of Medical Technology, Sorman, 7th April University,Libya Cancer is a common condition that affects millions of people throughout the world.Around the world, roughly 22 million people suffer from cancer; each year 10 million cases are newly diagnosed and 6 million people die of cancer. The World Health Organisation(WHO) estimates that these figures will rise over the next 20 years by up to 50%. Cancer can develop from various types of tissues. It causes an uncontrolled and uninhibited growth of the affected tissue type. Lymphatic system provides an important immune mechanism for the body and involved in the metastasis of cancer cells. Metastasis or spread of malignant tumor to neighbouring organs are the reason that most cancers eventually lead to the death of the patients. The lymphatic vessels are not generally visible in dissections but are the major route by which carcinoma metastasizes. The lymph nodes serve as filters. The cancer cells in lymph vessels migrate or metastasize to lymph nodes and tend to remain within them, proliferating and gradually destroying them. The lymphomas are the malignant manifestations of the cells of the lymph glands. They are normally considered in two major groups-Hodgkin’s diseases and the non-Hodgkin’s lymphomas and together account for approximately 4% of all cancers. 79 PO-21 HODGKIN LYMPHOMA Sami Alabed Abdulrahman African Oncology Institute, Sabratha, Libya Hodgkin lymphoma (HL) is a potentially curable malignant lymphoma. As classified by WHO, HL exists in 5 types. Four of these, nodular sclerosis, mixed cellularity, lymphocyte depleted, and lymphocyte rich, are referred to as classic Hodgkin disease.The fifth type, nodular lymphocyte predominant Hodgkin disease. HL have a bimodal distribution in both sexes, peaking in young adults (aged 15-34 y) and older individuals (>55 y). HL more common in male. HL is treated either with chemotherapy alone or in combination with radiotherapy. Our study includes the adult Hodgkin lymphoma patients with regular follow up at African Oncology Institute in the period from January 2006 to December 2008. A total of 37 cases of HL were seen with a M: F ratio of 1:1. 51% of cases were the age group between 15-25 years old. The histological subtype seen was nodular sclerosis (43%). Clinical stage at diagnosis were stage I (10.8%), stage II (29.7%), stage III (29.7%), and stage IV (29.7%). B symptoms were present in 75% of cases. 80 PO-22 NON-HODGKIN LYMPHOMA OF THE THYMUS Kauthar Ali Elmaawi, Sami Alabed Abdulrahman African Oncology Institute, Sabratha, Libya Diffuse large B cell lymphoma is the most common type of lymphoid malignancy, constituting 30–40% of adulthood non-Hodgkin lymphoma. Primary low-grade B-cell lymphomas of the thymus are rare, and usually presents with bulky mediastinal lesions. We report a case of diffuse large B cell lymphoma of thymus which is a 28 years old female presented with dry cough and dyspnea. Biopsy from anterior mediastinal mass (thymus) yielded histopathological characteristics consistent with diffuse large B cell non-Hodgkin lymphoma. Patient received 8 cycles of CHOP-R chemotherapy and radiotherapy to the mediastinum. The patient was followed for 2 months, during which time she exhibited no evidence of disease. 81 PO-23 PRIMARY NON-HODGKIN LYMPHOMA OF THE BONE: A CASE REPORT Sami Alabed Abdulrahman African Oncology Institute – Sabratha-Libya Primary non-Hodgkin’s lymphoma of bone (PBL) is rare, and generally presents as a single extensive and destructive bone lesion. Histopathologically, most cases present as diffuse large B-cell lymphoma, and T-cell lymphoma is rare. The incidence of PBL is7% of all malignant bone tumors, 4–5% of all extranodal non-Hodgkin lymphoma and less than 1% of all malignant lymphomas. We report a case of a diffuse large B-cell lymphoma of the clavicle, in which the patient presented with a diffuse swelling on the right clavicle. A subsequent biopsy and immunohistochemistry were instrumental in this diagnosis. The patient was treated with CHOP-R chemotherapy. The swelling regressed completely and lymph nodes disappeared following the chemotherapy regimen, with no sign of recurrence observed over the last seven months. 82 PO-24 ACUTE LEUKAEMIA: USEFULNESS OF RED BLOOD CELL CONCENTRATES TRANSFUSION IN FOR THE PREVENTION OF THE HEMORRHAGIC RISK F.Attaf, H.Tadj, M.Brahimi, S.Osmani, A.Arabi, B.Entasoltane, MA Bekadja. Service Hématologie et Thérapie Cellulaire, EHU 1er Novembre, Oran, Algeria Introduction: The management of acute leukemia requires besides of an adapted hospitalization structure (protected individual room), an efficient haematological supportive care and the availability of blood component materials in order to face the complications of the aplastic phase of post- induction chemotherapy The goal of our study is to demonstrate that a transfusion supply of RCC in time and in sufficient quantity allows preventing serious hemorrhagic risks threatening patient life, in case of severe thrombopenia. Patient and methods: On a period of 13 months (from January 2009 to January 2010), 23 patients with acute leukaemia were admitted to our Haematology department. 15 men and 8 women (sex ratio of 1.8) with a median age at the diagnosis was 40 years [16-73 years]. The diagnosis has been established by cytomorphology and flow cytometry, showing 6 ALL and 17 AML. The induction chemotherapy included for the ALL: GRALL 94 protocol and vincristine-prednisone, and for the AML: Aracytine 100 mg/m2-Daunorubicine 45 mg/m (3+7) protocol and ATRA-Idarubicine for patients with (AML3). Prophylactic treatment of the infections associated the Bactrim®, Ciprolon®, Fluconazole and Aciclovir. A curative antibiotherapy has been started if there was an appearance of a 38.5°C documented or not fever. Anemia and severe thrombopenia were treated by RCC = Red blood cell concentrates, CPP = Plateletpheresis product. Two groups of patients have been studied, those having a sufficient transfusional regiment with maintain of their Hb level between 11 and 12 g/dl with platelet count <15.000/μl (first Group) and those having had some difficulties to be transfused properly and of which the level of Hb was between 6 and 10 g/dl with a platelet count <15.000/i.il (G2). The statistical assessment was based on the χ 2 test. Results: 23 patients with acute leukemia have been collected. The classification was as follow: 06 ALL (1 ALL T, 5 ALL BS), 17 AML (2M1, 4M2, 1M3, 2M4, 6M5, 1M6, 1M7). The median time of survival = 4 months [1-9 months]. The rate of post-induction response for the ALL: 5 CR and 1 death, for 83 the AML,: 12CR (71%), 4 deaths (24%), 1 partial responsanswer. The median time of the phase of aplasia was 24 days [16-37 days]. The table below shows the results of the transfusion of RCC correlated to the haemorrhagic syndrome. median age: median Number of RCC median Number of CPP Absence of haemorrhage: Minimal haemorrhage: Serious haemorrhage: Death by haemorrhage: first group (n=15) Hb [11-12 g/dI] platelets <15000/p.l 43 years [16-73] 11[8-20] 3 [1-5] 12 (80%) 3 (20%) 0 (0%) 0 (0%) second group (n=8) Hb [6-10 g/dI] platelets <15000/pi 46 years [16-58 ] 6 [4 - 15] 4 [2 - 6] 2 (25%) 0 (0) 6 (75%) 5 (83%) (n = number of patients, Hb = haemoglobin, CCR = Red blood cell concentrates, CPP = Plateletpheresis product) Conclusion: During the severe thrombopenia of the aplastic phase of post induction of the acute leukemias, the rate of hemoglobin (<10 g/dl or 11 g/dl) can be considered as predictve a factor of the intervening of the hemorragic syndrome and it’s severity. Our preliminary results suggest that hemoglobin of 11 g/dl is a protective factor against this risk. It should be validated by the pursuit of this work 84 PO-25 EVALUATION DU PROTOCOLE LINKER DANS LE TRAITEMENT DES LEUCEMIES AIGUES LYMPHOBLASTIQUES DE L’ADULTE K.Ait-Seddik, N.Dali, M.Allouda, O.Ouanes,S.Gherras, H.Aftisse, H.Ait-Ali Service d’hématologie CHU de TIZI OUZOU Introduction: Les leucémies aigues lymphoblastiques représentent 20% des leucémies aigues de l’adulte. Différents protocoles d’induction ont été utilisés: le protocole linker a été introduit dans notre service en 2000 et représente le protocole de choix dans le traitement des LAL de l’adulte jeune. Il comporte une polychiomiothérapie d’induction associant Rubidomycine 50mg/m2 (3j), Vincristine 1,4mg/m2 (j1-j8-j15-j22) et Asparaginase 6000 UI/m2 (j17 à j28) et Prednisone 60mg/m2 à 28j. - Une conclusion BFM comportant: Purinéthol, Aracytine et Endoxan. - Plus 9 réinductions mensuelle M1 à M9 et un traitement d’entretien associant Purinéthol et Méthotréxate pendant 02 ans. Patients et méthodes: 62 patients ont été traités de janvier 2000 à décembre 2009. Les extrêmes sont de 15 à 57 ans: avec un âge moyen de 27 ans. 25 sont des femmes et 37 sont des hommes avec un sexe ratio H/F 1.5. Les patients ont tous reçu le traitement linker associé un protocole prophylaxie neuroméningé Résultats: Chez les 62 patients ainsi traités. 16 soit 25% sont décédés en induction et 08 échecs soit 13%. 38 soit 62% sont mis en rémission dont la médiane est de 22 mois (02 à 111mois). Au total: devenir des 38 malades en RC: - 18 vivants en RC, médiane de suivi: 35 mois. - 16 rechutes → dont 1 seul vivant en 2e RC: après greffe, délai de suivi: 70 mois. - 4 DCD (réinductions). Conclusion: Le TRT linker a permis d’améliorer le pronostic des leucémies aigues lymphoblastiques de l’adulte dans notre service mais il reste insuffisant pour le maintien de la survie à long terme. 85 PO-26 ASPECTS CLINIQUES ET BIOLOGIQUES DE LA LEUCEMIE MYELOIDE CHRONIQUE K. Benallaoua, F.Fergane, W.Chaba, H.Laga, R.Drif, S.Dechir, N.Dali, O.Ouanes, K.Ait Seddik, M.Allouda, S.Gherras, H.Aftisse, A.Graine Et Pr H.Ait Ali Service d’hématologie CHU de TIZI OUZOU Introduction: La leucémie myéloïde chronique est un syndrome myéloprolifératif rare représentant 15 % des leucémies de l’adulte dont l’étiologie reste inconnue dans la majorité des cas. Les traitements conventionnels tels l’hydrea ou le busulfan ne modifient que très peu la survie, et l’allogreffe de moelle osseuse permet de guérir mais ne peut être proposée qu’à un nombre limité de patients. Le pronostic s’est nettement amélioré grâce à des thérapeutiques innovantes et ciblées (imatinib, dasatinib, interféron). Nous rapportons ici notre expérience sur une série de 44 patients colligés sur une période de 05 ans (2005-2009). Patients et Methodes: Patients: De 2005 à 2009 nous avons répertorié 44 patients atteints de LMC, 23 sont des hommes et 21 des femmes, le sex-ratio est de 1,09. L’âge moyen est de 52 ans avec des extrêmes de 20 et 89 ans avec deux pics de fréquence 40-50 ans et supérieur à 60 ans. Méthodes: Tous les patients ont été recrutés à partir de la consultation, le diagnostic était posé sur la clinique (splénomégalie) et la biologie (hémogramme). Resultats: Le délai diagnostic est d’environ 01 à 06 mois et la présentation clinique est caractérisée par une splénomégalie chez 39 patients(88%) allant du type I à V associée à une hépatomégalie 04(09%),une pâleur cutanéomuqueuse 24(54%),un syndrome hémorragique 06(13%) et 03 (07%)pts étaient asymptomatiques. Sur le plan biologique ; 38(86%) avaient une hyperleucocytose>150000/mm3, 22(50%) un taux d’Hb <10gr/dl et 07(16%) une thrombopénie et 13(28%) une thrombocytose. La quasi-totalité des patients étaient en phase myélocytaire 37(84 %) et seulement 05(11%) en accélération et 02(05%) en acutisation. 37patients (84 %) ont un Score de SOKAL intermédiaire et 04 (09 %) élevé et 03 (07 %) faible. 86 Conclusion: Le diagnostic de leucémie myéloïde chronique est facile et se fait précocement mais malheureusement à des stades avancés (SPMG III à V) d’où l’intérêt d’un dépistage précoce (examens systématiques). Par ailleurs une étude cytogénétique et moléculaire est impérative dés la suspicion d’un syndrome myéloprolifératif à des stades précoces. 87 PO-27 RITUXIMAB-BASED CHEMOTHERAPY FOR AUTOIMMUNE CYTOPENIA OF CHRONIC LYMPHOCYTIC LEUKEMIA S.Bougherira – F.Grifi Department of Haematology – CHU ANNABA. ALGERIA Background: Chronic lymphocytic leukemia (CLL) is characterized by an acquired immune defect that can cause autoimmune complications, including anemia (AIHA) and thrombocytopenia (ITP). AIHA occurs in 10% of advanced stage CLL patients; ITP occurs in 2 – 3% in early stage disease and may be a presenting manifestation. And there are limited effective treatment options for steroid refractory autoimmune cytopenias. Rituximab, an active agent against B cell malignancies, has also been noted to be active in certain autoimmune hematologic disorders. The purpose of this study was to evaluate the safety and efficacy of Rituximab-based chemotherapy in this complication of CLL. Patients & methods: This prospective study examines the outcome in CLL patients with autoimmune phenomena (AIHA, Evans’ syndrome). Five patients were treated at our institution. Two patients who had been previously treated with alkylating agents (CHOP/CVP), one of them had received Fludarabine, two patients were newly diagnosed and had not receive any treatment. Treatment regimen (RCD): Rituximab was given at a dose of 375/m2 intravenously (i.v.) on day 1 (D-1). Dexamethasone 40 mg i.v. D-1. Cyclophosphamide at a dose of 1000 mg (total dose) i.v D-1. The treatment was repeated every 2 weeks of a total of six cycles. Results: Median age was 65 years (range 44 -74) and there were five male patients. All of them had Binet stage C disease, and ECOG performance status was 1. Response in autoimmune cytopenias was evaluated by frequent blood counts and Coombs test. 4 of five patients achieved a remission of their cytopenia. One of them is still received the treatment. Median pretreatment hemoglobin was 6.7 g/dl and post-treatment hemoglobin was 12.3 g/dl. The mean pretreatment platelet was 147 G/L and post treatment was 213 G/L. Three patients converted to Coombs negative after RCD. Median duration of response was 14 months. The patients were evaluative for toxicity: grade ¾ toxicity neutropenia was noted in one patient and needed supportive care by haemopoitic growth factors. One patient died of progressive disease (CLL) 06 months after the response to RCD therapy. 88 Conclusion: Autoimmune phenomena, largely related to blood cells, are based in the immune dysregulation of CLL. Our results indicate that a rituximab-based combination regimen (RCD) is highly effective in treating this complication of CLL, and show a safety profile. 89 PO-28 CHRONIC LYMPHOCYTIC LEUKEMIA: ABOUT A SERIES OF 40 CASES R. Messaoudi,F.Ouadah H.Amirouche.El Mestari.Pr Z Zouaoui University Hospital of Sidi Bel Abbes Algeria Introduction: Chronic lymphocytic leukemia is the most common leukemia in Western countries with a median age at diagnosis less than 65 years. Methods: This is a retrospective study of 10 years (2000-2009) included patients followed at the hematology department for chronic lymphocytic leukemia. Results: 40 observations were analyzed, 30 men (75%) and 10 women (25%), sex ratio: 3 and the average age of 70.70 + / - 11.3 years. According to the Binet classification, we note 20% of stage A, 25% of stage B and 55% of stage c.the mean hemoglobin was 10.32 + / - 2.95 g / dl. The average platelet count is 164.242/mm 3 with a lymphocytosis averaging 99,720 + / - 12930/mm 3. 30 patients received chimiothérapie. Overall median survival was 51 months out of 10 years. Evolution is enameled with a case of Richter’s syndrome and 60% of patients who have infectious syndrome. Conclusion: Chronic lymphocytic leukemia is common in elderly patients, whose diagnosis is made late in our series. The value of early detection to improve their care. 90 Translation to French PO-28 MANIFESTATIONS THROMBOTIQUES RÉVÉLATRICES D’UNE LEUCÉMIE MYÉLOÏDE CHRONIQUE R.Messaoudi1, F.Ouadeh2, A.Meghraoui2.Hadjeb2, PrZ.Zouaoui Service d’Hématologie, Centre Hospitalo-universitaire de Sidi Bel Abbés, ALGERIE. Mots clefs: leucémie myéloïde chronique, thrombose, priapisme. Introduction: La leucémie myéloïde chronique est un syndrome myéloprolifératif chronique associée une augmentation du risque thrombotique qui peut toucher les artères de grands, moyens et petits calibres et le système veineux. Les mécanismes impliqués sont multiples et intriqués (stase, état pro-thrombotique et envahissement vasculaires). Observations: Il s’agit de 3 patients âgés respectivement de 49ans, 33ans, 21ans ne présentant aucuns antécédents pathologiques particuliers dont le diagnostic d’une leucémie myéloïde chronique a été posé suite a l’exploration d’une complication thrombotique type priapisme ayant nécessite une intervention chirurgical au niveau du service d’Urologie. Conclusion: Les complications thrombotiques peuvent précéder un syndrome myéloprolifartif type leucémie myéloïde chronique dans de rares cas d’où l’intérêt d’une exploration hématologique rapide (hémogramme et frottis de sang) avant tous actes chirurgicales et traiter précocement et efficacement par un traitement spécifique (étiologique) afin d’améliorer le pronostic. 91 PO-29 LES INFECTIONS RENCONTRÉES AU COURS DES NEUTROPÉNIES FÉBRILES INDUITES PAR CHIMIOTHÉRAPIE D’INDUCTION DES LEUCÉMIES AIGUES OU ACQUISES AU COURS DE L’APLASIE MÉDULLAIRE N. Dali, m. Allouda, o. Ouanes, s. Gherras, k. Ait-seddik, h. Aftisse, h. Ait-ali Service Hematology Chu Tizi-Ouzou, Algeria Introduction: Les neutropénies induites par le traitement des hémopathies malignes aigues, sont à l’origine d’infections fréquentes et très souvent grave qui déterminent le pronostic de ces patients. La neutropénie est également un événement régulièrement rencontré au cours d’une aplasie médullaire. Le risque infectieux est proportionnel à la sévérité et la durée de la neutropénie, il représente la cause principale de décès chez les malades en aplasie si des mesures préventives et précoces ne sont pas instaurées. Patients et Méthodes: Il s’agit d’une étude rétrospective menée sur une période de 03 ans (2006-2008) dans laquelle nous avons répertorié les épisodes fébriles en relation avec une infection chez des patients neutropeniques. L’étude a conserné 150 patients (89 LAM, 38 LAL, 5 LA non typée, 18 aplasies médullaires). L’âge de nos patients varie entre 17 à 86 ans avec une médiane de 44 ans. Il s’agissait de 84 femmes et 66 hommes. Le statut hématologique: taux moyen: GB / 2000/mm3, PN: 100/mm3, Hb: 07g/dl, Plq: 30000/mm3. La recherche étiologique consiste, en plus d’un examen clinique soigneux, à pratiquer systématiquement une enquête bactériologique: hémocultures, bilan radiologiques et des prélèvements dirigées par la symptomatologie clinique. Résultats: 117 /150 (78%) patient ayant présenté, un ou plusieurs épisodes fébriles, chez lesquels 207 épisodes fébriles d’origine infectieuse ont été diagnostiqués et repartis comme suit: - infections cliniquement documentées: 53 (25%). - Les infections de la sphère ORL (22) les plus fréquentes, cutanées (13) pulmonaire (07), digestif (08), urinaire (03). - Infections microbiologiquement documentées: 67 (46%) (37 hémocultures + 30 prélèvements): bactériémies à bacilles gram négatif (BGN) (28), bactériémies à cocci gram positif: 08, et 1 candidose systémique. L’enquête bactériologique a révélé plusieurs souches bactériennes: BGN (59 %) représentés principalement par le klebsiellas pneumonoe (12,5) et eccherichia coli (12%). Les coci gram (+) ne représentent que 29% de l’écologie du service. On ne note que 14 % de candida albicans. - infections non documentées, mais régressant sous antibiothérapies probabilistes: (42 %). 92 Commentaires: Dans cette étude, les résultats de la recherche bactériologique ne correspondent pas à ceux décrits dans la littérature avec un pourcentage très important de BGN contrairement aux coccis gram (+) et ceci peut être expliqué par l’absence d’utilisation des cathéters centraux au sein de notre service. - les infections non documentées rejoignent les données de la littérature. Conclusion: Un patient neutropenique constitue un terrain très favorable aux infections surtout au milieu hospitalier avec un risque de mortalité. Une difficulté d’un diagnostique microbiologique, justifie une antibiothérapie probabiliste visant à couvrir la majorité des germes, à modifier ou à optimiser en fonction de l’état du patient. 93 PO-30 LEUCEMIES AIGUES PROMYELCYTAIRES: ASPECTS CLINIQUES, BIOLOGIQUES ET THERAPEUTIQUES N. Dali – K. Ait-Seddik – M. Allouda – O. Ouanes S. Gherras – H. Aftisse – H. Ait-Ali Service Hematology Chu Tizi-Ouzou, Algeria Introduction: La leucémie aigue promyélocytaire (LAP) représente 5% des LAM mais elle est tout à fait singulière par ses mécanismes d’oncogenèse parfaitement identifiés et par son pronostic favorable. Nous rapportons ici le cas de 15 patients atteints de LAP pris en charge au service d’hématologie de TIZI-OUZOU. Matériels et méthodes: Il s’agit d’une étude rétrospective réalisée sur dossiers chez 15 patients atteints de LAP diagnostiqués sur une période de 06 ans (03/2004 au 03/2009). L’âge moyen au diagnostic est de 36 ans avec des extrêmes allant de 16 à 70 ans: 08 femmes et 07 hommes avec un ratio (F/H): 1,14. Le diagnostic a été posé par l’étude morphologique des frottis sanguins et médullaires selon la classification FAB. Tous les malades ont bénéficié d’un traitement symptomatique (transfusions sanguines, plaquettaires et PFC). Le traitement spécifique a comporté une induction par chimiothérapie selon le protocole (rubidomycine – aracytine + atra) pour 11 patients. 03 patients n’ont pas été traités car décédés précocement. Résultats: - sur le plan clinique: un syndrome anémique et hémorragique ont été retrouvés chez tous les patients dont 03 présentaient d’emblée un tableau grave: hémoptysies et hémorragies cerebro-méningées. Le syndrome tumoral a été absent dans tous les cas - sur le plan biologique: l’hémogramme a objectivé: une anémie chez tous les patients. Le taux d’hémoglobine moyen est de 08,5g/dl. Une hyperleucocytaire dans 09 cas (60% cas) avec un taux moyen de 16040/ mm3. Le taux de plaquettes varie de 15000 à 106000/mm3, correspondant à un taux moyen de 34333/mm3. 05 patients présentaient des signes de mauvais pronostic: une hyperleucocytose > 5000/mm3 et une thrombopénie < 40.000/mm3. Le caryotype n’a pu être réalisé. La CIVD a été positive chez 10 malades (66%). - sur le plan évolutif: 03 patients sont décédés avant traitement d’hémorragies cérébrales et hémoptysies (non évaluables). 03 malades sont décédés en induction dont 02 suite à un syndrome d’ATRA et le 3ème par infection. La rémission complète a été obtenues chez 09 patients (82%). Ces 09 pts sont toujours vivants avec un délai médian de suivi de 40 mois (09 mois – 69 mois). 94 Conclusion: Notre petite série de LAP reflète le caractère favorable de cette hémopathie comme en témoigne le taux de rémission complète et la médiane de suivi. Le problème que pose cette leucose est de résoudre les problèmes de la CIVD sévère qui représente la principale cause de mortalité. 95 PO-31 CHRONIC MYELOID LEUKEMIA WITH MENINGEAL LOCATION. ABOUT ONE CASE F.Belhadri, F.Hariéche, N.Abdennebi, S.Zeghouati, S.Saidani, K.Tarhi, RM.Hamladji Department of Hamatology and Bone Marrow Transplantation; Pierre and Marie Curie center, Algiers, Algeria Introduction: The meningeal location of chronic myeloid leukemia (CML) is exceptional, no case has been reported in the literature. We report a patient of 52 years old who have CML with meningeal location. Comment: The patient of 52 years old who consults his physician in emergency, the leukocytosis was found. Physical examination objectified splenomegaly type III. The blood count showed leukocytosis 175000/mm3 with myeleamia 41%. He has treated by Hydrea (2000mg capsules per day). One week later he consults again for headache,optic fundus examination reveals the retinal hemorrhage and a normal CTscan of brain. He was sent to hematology department. Physical examination at admission showed a patient with average general condition without meningeal syndrome, without tumor, the blood count showed leukocytosis 149,000 with a myeleamia 38%, Hb level 12.3 g/dL, platelet 332,000 / mm3. The patient received supportive treatment with maintenance of Hydrea, a week after the patient was in complete hematologic remission (CHR) with persistent severe headache; refractory to analgesics, a optic fundus examination shows remade punctiform retinal hemorrhage on the right eye, analysis of cerebrospinal fluid (CSF) showed a CSF glycorrachia at 0, 21 g / l and CSF protein 0.58 g / l, hypercytose to 550/mm3 (myelocytes and metamyelocytes)and 83 RBC and a direct negative bacteriological examination. The RX chest, CTscan and MR of brain are normal. The search for a transcript BCR-ABL positive type b2 a2 confirming the diagnosis of CML. Therapeutically patient received intrathecal chemotherapy every tow days (a total of 9 injections) with the following normalization of CSF. The treatment was completed by cranial radiation to 24 gy. The patient was treated by dasatinib with 2 capsules per day to 50mg depending on availability and tolerance. After a year of follow up the patient is still in CHR. Conclusion: The unusual meningeal location in CML was diagnosed in this patient because of symptoms with intense headache rebel to analgesics. The treatment of choice in this case is the first Dasatinib intension which penetrates the meningeal contrast to imatinib. 96 PO-32 ADULT GAUCHER DISEASE (GD) IN ASSOCIATION WITH CHRONIC MYELOID LEUKEMIA (CML). A CASE STUDY F. Belhadri, H. Moussaoui, F. Harièche: N. Abdennebi; D. Benali M. Maidat; RM.Hamaldji Department of Haematology and Bone Marrow Transplantation; Pierre and Marie Curie center, Algiers, Algeria Introduction: Gaucher disease (GD) is an inherited recessive autosomal metabolic defect due to a deficiency of the lysosomal enzyme β-glucocerebrosidase. The GD may be associated with neoplastic lesions (myeloma, NHL, melanoma and pancreatic cancer). We report the case of a woman of 46 years old with coexisting type I Gaucher’s disease (GD) and chronic myeloid leukemia (CML). Comment: The woman of 46 years old, without notable medical history, followed by gastro-enterologist for GD type 1 for two years The patient suffered from hepatosplenomegaly and thrombocytopenia. After one year of follow up, she presented a 30000/mm3 Leukocytosis with myeleamia 28% (4% promyelocytes, myelocytes 15%, metamelocytes 9%), a search of a transcript BCR-ABL was positive b2a2 type. Examination showed a patient with average general conditions, a hepatosplenomegaly with a larger liver to16 cm and a larger spleen to 26cm, the blood count showed leukocytosis with 73000/mm3 with myeleamia 28%, hemoglobin level to 11, 6g/dl and thrombocytopenia à 24000/mm3. A splenectomy was performed before starting treatment specifically because of the large volume of spleen and thrombocytopenia. A month after the splenectomy the patient presents with a good general conditions, normalization of blood counts (WBC: 9500/ mm3, Hb: 12g/dl, platelets: 250000/mm3), a normal blood smear and extended portal thrombosis, treated by anticoagulants (VKA). After four months of monitoring the patient presented a progressive increase of leukocytosis 28000/mm3 without myeleamia. A check of the transcript BCR-ABL b2a2 confirms the type has a rate of 2.65. The patient was treated by Hydrea (imatinib has not been prescribed because the drug interferes with the AVK). After 16 months of follow up the patient is still in hematologic remission with Hydrea. Conclusion: The GD is a rare disease, but has several points of interest in hematology, in diagnosis of the hematologic manifestations and its frequent association with hematologic malignancies which pathophysiological links are not known at this time. 97 PO-33 ASPECTS CLINIQUES ET BIOLOGIQUES DE LA LEUCEMIE MYELOIDE CHRONIQUE K. Benallaoua, F.Fergane, W.Chaba, H.Laga,R.Drif, N.Dali, O.Ouanes, K.Ait Seddik, M.Allouda, S.Gherras, H.Aftisse, A.Graine Et Pr H.Ait Ali Service d’hématologie CHU de TIZI OUZOU Introduction: La leucémie myéloïde chronique est un syndrome myéloprolifératif rare représentant 15 % des leucémies de l’adulte dont l’étiologie reste inconnue dans la majorité des cas. Les traitements conventionnels tels l’hydrea ou le busulfan ne modifient que très peu la survie, et l’allogreffe de moelle osseuse permet de guérir mais ne peut être proposée qu’à un nombre limité de patients. Le pronostic s’est nettement amélioré grâce à des thérapeutiques innovantes et ciblées (imatinib, dasatinib, interféron). Nous rapportons ici notre expérience sur une série de 44 patients colligés sur une période de 05 ans (2005-2009). Patients et Methodes: Patients: De 2005 à 2009 nous avons répertorié 44 patients atteints de LMC, 23 sont des hommes et 21 des femmes, le sex-ratio est de 1,09. L’âge moyen est de 52 ans avec des extrêmes de 20 et 89 ans avec deux pics de fréquence 40-50 ans et supérieur à 60 ans. Méthodes: Tous les patients ont été recrutés à partir de la consultation, le diagnostic était posé sur la clinique (splénomégalie) et la biologie (hémogramme). Resultats: Le délai diagnostic est d’environ 01 à 06 mois et la présentation clinique est caractérisée par une splénomégalie chez 39 patients(88%) allant du type I à V associée à une hépatomégalie 04(09%),une pâleur cutanéomuqueuse 24(54%),un syndrome hémorragique 06(13%) et 03 (07%)pts étaient asymptomatiques. Sur le plan biologique ; 38(86%) avaient une hyperleucocytose>150000/mm3, 22(50%) un taux d’Hb<10gr/dl et 07(16%) une thrombopénie et 13(28%) une thrombocytose. La quasi-totalité des patients étaient en phase myélocytaire 37(84 %) et seulement 05(11%) en accélération et 02(05%) en acutisation. 37patients (84 %) ont un Score de SOKAL intermédiaire et 04 (09 %) élevé et 03 (07 %) faible. 98 Conclusion: Le diagnostic de leucémie myéloïde chronique est facile et se fait précocement mais malheureusement à des stades avancés (SPMG III à V) d’où l’intérêt d’un dépistage précoce (examens systématiques). Par ailleurs une étude cytogénétique et moléculaire est impérative dés la suspicion d’un syndrome myéloprolifératif à des stades précoces. 99 Translation to English PO-33 CLINICAL AND BIOLOGICAL ASPECTS OF CHRONIC MYELOID LEUKEMIA (CML) K. Benallaoua, F.Fergane, W.Chaba, H.Laga, R.Drif,, N.Dali, O.Ouanes, K.Ait Seddik, M.Allouda, S.Gherras, H.Aftisse, A.Graine Et Pr H.Ait Al Service Hematology Chu Tizi-Ouzou, Algeria Introduction: Chronic myeloid leukemia is a rare myeloproliferative disorder characterized by the increased and unbalanced growth of myeloid cells in the bone marrow and their accumulation in the blood, it represents 15% of all cases of adults’ leukemia and until now the cause is unknown. Conventional treatments are given (hydroxyurea, busulfan) with no real surviving benefit, but now a targeted therapies have been developed (imatinib, dasatinib, nilotinib, and immunotherapy). Stem cell transplantation is only recommended for some patients. We report here our experience about 44 patients during a five years period (2005-2009). Patients and Methods: Patients: from 2005 to 2009 we included 44 patients with sex-ratio=1, 09. The average age is 52 within a range of 20 and 89 with two peaks of frequency 40 -50 years and >60 years. Methods: all patients were chosen from the consultation and the diagnosis was determined according to the clinical symptoms (splenomegaly) and the biology (complete blood count CBC) Results: The diagnosis deadline is about 01 to 06 months and the clinical manifestations are characterized by a splenomegaly (39 patients –pts-88%) type I to V, associated to an hepatomegaly (04 patients 09%),pale skin (24 patients 54%), hemorrhages (06 patients 13%) and 03 patients (07%) were asymptomatic. Biologically, 38 patients (86%) had an elevated white blood cell count >150000/mm3, 22 patients (50%) hemoglobin <10gr/dl, 07 patients (16%) thrombocytopenia and 13 patients (28%) thrombocytosis. 37 patients (84%) were diagnosed in chronic phase and only 05 patients (11%) in accelerated phase, 02 patients (05%) in blast crisis. 37patients (84%) have intermediate risk (SOKAL SCORE), 04 patients 09% with elevated risk and 03 patients (07%) with low risk. 100 Conclusion: The diagnosis of CML is easy and can be made early but unfortunately in latest stages (SPMG III to V) so an early detection is necessary (systematic tests). However, a cytogenetic and molecular analysis is imperative once a myeloproliferative disorder in its early stages is suspected. 101 PO-34 LES LEUCEMIES AIGUES: DE LA MORPHOLOGIE AU SEQUENÇAGE IMMUNOPHENOTYPIQUE PAR CYTOMETRIE EN FLUX SE Belakehal, H Mansour, S Baghdad, MC Rahali, A Maatalah, L Lazfen, D Saber-Cherif, FZ Ardjoun Service d’hématologie, Hôpital Central de l’Armée, Alger, Algérie Introduction Parmi les analyses pratiquées dans un service d’hématologie, l’étude immunophénotypique par cytométrie en flux (CMF).

Taoussi, Y. Bouchakor, N. Rekab, S. Oukid, H. Brahimi, MT Abad Department of Haematology, EHS ELCC Blida, Algeria. Background: Chronic lymphocytic leukaemia (CLL) affects more and more patients under 65 years legitimately eligible for treatment inducing complete remission or at least prolonged event free survival; conventional therapeutic approaches do not reach these objectives. Fludarabine in association with Cyclophosphamide results in optimal responses. Aims: To evaluate efficacy and tolerance of FC in our country. Patients and methods: From January 2007 to December 2009, 34 CLL treated with FC: 7 women, 27 men (sex ratio = 3.8). Average age = 58.9 years. Median leucocyte count = 145 x 109/l. Immunophenotyping: 29 patients: Matutes 5: 13 cases, 4: 14, 3: 2. CD38 > 30% = 17 cases. Hypogammaglobulinemia <7g / l: 6 cases. Bone marrow biopsy: 34 (diffuse: 27, nodular: 3, interstitial: 3,1failed). Binet stage: Stage B: 13, stage C: 21. Cytogenetics in 17 patients: 5 with deletions of 2 copies of 13q14 and 1 associated with a 6q21 deletion, 4 trisomy 12 and one associated with 6q21deletion, 3 ATM deletions associated with a 6q21 deletion, one p53 deletion associated with a 6q21 deletion, no abnormality in 4 cases. FC: Fludarabine 25 mg / m² i.v (d 1-3), Cyclophosphamide 250 mg / m² i.v (d 1-3) every 28 days; prophylaxis by antimicrobial and antiviral daily during treatment and 6 months after completion of treatment. Evaluation of response according to NCI criteria. Results: For 22 patients that have completed 06 cycles of FC: CR: 09 (40%), PR: 02 (09%), NPR: 10 (45.4%), Failed: 01 (4.5%). Toxicity evaluated in 32 patients who received ≥ 3cycles of FC: 165 cycles: neutropenia grade 3 and 4: 51.5% ; lymphocytopenia: 29%; thrombocytopenia <50x10 ³ / mm3 at 5.4%. The average duration of aplasia: 10 days without GCSF. 25 infectious episodes (15.1%): lung 68% (including one case of pulmonary tuberculosis), urinary 24%, chicken pox 8%. Becoming of patients: 22 patients have ended their treatment: One died 4 months after failed treatment: overall survival 12 months. 2 patients with PR received a consolidation with 3 cycles of FC: CR in one case nPR in other case. Among the 10 CR: 3 patients relapsed after a period 106 of CR of 14, 15 and 25 months. The remaining 7 are still in CR: EFS = 3 to 29 months. Among 9 nPR: 2 were lost to follow in nPR after a period of follow-up 6 and 10 months and one patient relapsed after an EFS of 12 months; 7 patients are still alive in nPR with EFS 1 to 27 months. 09 patients are under treatment. 03 patients died before the end of treatment: 1 due to progression of the disease, 2 with severe pulmonary infection; death related to toxicity in 5.8%. Overall rate of death over 3 years of follow-up = 14.7%. Conclusion FC protocol improved significantly the overall response rate, the complete remission rate and the progression free survival time.FC combination caused severe side effects; the death rate in our study is partly correlated with the high rate of stage C and the predominance of cytogenetic abnormalities with poor prognosis. 107 PO-36 CONVENTIONAL AND MOLECULAR CYTOGENETIC (FISH) FOR ASSESSING DIAGNOSIS AND PROGNOSIS OF HEMATOLOGIC MALIGNANCIES S. Taoussi, M. T. Abad Department of Haematology, EHS ELCC Blida, Algeria Introduction Fluorescent in situ hybridization (FISH), providing additional diagnostic, therapeutic and prognostic factor in the evaluation of hematologic malignancies. To improve diagnosis and treatment of hematologic malignancies in our country, we apply the cytogenetic examinations. Methods We present the results of 136 hematologic malignancies typed by these procedures (chronic myelogenous leukaemia (CML), chronic lymphocytic leukaemia (CLL), multiple myeloma (MM), acute leukemia) (AL). For each patient, we perform a metaphase and interphase FISH using a panel of probes dedicated to each disorder: CML: bcr-abl probes single and or double fusion; CLL: CEP 12 probe, 13q14-q34 probe, ATM-p53, 6q21 probe. AML: CBFB t (16, 16) inv (16) probe, AML / ETO t (8; 21) probe, PML / RARA t (15, 17) probe, MLL (11q23) probe; ALL: bcr-abl simple fusion probe; myeloma: 13q14-q34 probe. Results 136 malignancies were studied: CML: 54 cases, LLC: 34 cases, MM 30 cases, LA: 18 cases. CML Group: CML in chronic phase: 67 examinations of 54 patients: - 31 at diagnosis (30 in chronic phase and 1 in blast crisis). The signal fusion Bcr-Abl was found in 30 cases, 1 case confirming a complex abnormality t (1, 9, 22) found on the karyotype. - 23 in therapeutic evaluation: 20 in chronic phase at 3, 6, 9, and 12 months of taking imatinib, 3 cases in acutisation, for assessing results of therapy. CLL Group: 34 patients: 12 including seven isolated trisomy 12, twelve 13q14deletions including nine isolated (two: loss of 2 copies and two: loss of one copie), 5 ATM (11q22.1) deletions with two isolated, 4 P53 deletions all associated, three 6q21 deletions associated with ATM, p53 and 13q14, no abnormality in 7 cases. Myeloma Group: 14 of 30 patients with a 13q14 deletion and 4 cases with abnormal numbers. AL Group: 7 LAL: failure of 1 in culture, presence of bcr-abl signal in 2 / 6 cases. AML: 11 cases: PML-RAR positive in a case of LAM3. Invert 16: 2/4 cases; t (8; 21) and MLL 108 gene rearrangement studied in 5 cases of AML2, results in progress. Comments The assessment of therapeutic response to imatinib by karyotyping and metaphase /interphase FISH allowed us to exercise our terms of monitoring cytogenetic remission patients and guide the therapeutic approach. In chronic lymphocytic leukaemia, the importance of abnormalities of poor prognosis (ATM del, p53 del) and atypical (+12) gives a specific profile for our patients to be confirmed on a larger series. In multiple myeloma: the rate of del 13q14 joined that of the literature. The prognostic evaluation of LA is in progress. 109 PO-37 PYODERMA GANGRENOSUM (PG) AND ACUTE LEUKEMIA, ABOUT THREE CASES Yachekour. T1, Aberkane M1, Bensmaine. M.A1, Zouani.S1, Taibi K1, Touhami F1, boudjouras yahia,A 1, Touhami.H1. Sairi.H2, Hambil.N2, 1 Service hematology CHU of Oran, ALGERIA 2 Service of dermatology CHU of Oran.ALGERIA Introduction: The pyoderma gangrenosum (PG) is an ulcerative neutrophilic dermatosis of quick change, of etiology unknown, chronic, very invalidating, generally occurring in partnership with a systemic disease, during inflammatory entéropathy (rectocolitis hemorrhagic), characterized in particular by the presence of ulcerations irregular, purplished red, whose edges are dug in purulent rabbit burrow. More rarely in partnership with malignant hemopathy especially the MDS, In our publication bringing back three cases of PG to us associate has IT. Patients and methods: 1° Case: A 26 years old an, in January 2009 PG in post partum, very wide woman with the lips, center, backs of the hands and feet. The patient was trachéostomizing, follows of a laryngé oedema. in August 2009 a LAM5 is diagnosed, treated by Protocol mini CHA, patient dead 17 days after induction in a septic table of shock. 2° Case: 32 years old young woman, followed in dermatology for a PG, was addressed to us for the exploration of a arégénératif anemia normochrome normocytic. With the myelogram, one discovers a refractory anemia with excess of blastes at 12%. Under Aracytine with low dose, survival was 11 months. 3° Case: A 42 years old man, followed in hematology and dermatology for a PG, with vitiligo and an anemia of Biermer. At the end of one year of treatment for the PG and Biermer, the patient presents a pancytopenia progressive installation. The myelogram revealed the invasion of marrow by 22% of blastis of pace myéloide. Put under weak Macaw-C proportions, survival was 9 months. Comments: The frequent association of the PG to the hémopathy is known and tends to return the PG like a symptom very serious precedent of the hémopathy of all kinds. The forecast of the PG as that of the diseases which join it remain very held. 110 PO-38 ASSOCIATION LEUCÉMIE AIGUE MYÉLOBLASTIQUE ET TUBERCULOSE MULTIFOCALE S.En-nasri,S.Nait Mbarek,H.Nafil,L.Mahmal Service d’hematologie.CHU Med VI.Marrakech,Maroc La tuberculose est une infection opportuniste très fréquente chez l’immunodéprimé notamment les patients porteurs d’hémopathies malignes chroniques. Mais la tuberculose multifocale reste une forme rare dans le contexte des leucémies aigues. Nous rapportons le cas de Mr N.M âgé de 42 ans, sans antécédent pathologique, qui a présenté progressivement depuis 5 mois, un syndrome d’insuffisance médullaire complet, et des poly adénopathies cervicales. L’examen clinique trouve un patient fébrile à 39 °C, pâle, et qui a des poly adénopathies cervicale, sans hépatomégalie ni splénomégalie. L’hémogramme montre une anémie à 7g/dl normochrome normocytaire,une hyperleucocytose à 56000/mm3 avec 90% des blastes,et une thrombopénie à 14 000/mm3. Le myélogramme réalisé était en faveur d’une leucémie aigue myéloblastique type 4, avec R +++,M+,et plus de 20% de myéloblastes. L’immunophénotypage confirme le diagnostic de leucémie aigue myéloblastique. Le patient était mis sous poly chimiothérapie d’induction selon le protocole AML -03. L’évolution a été marquée par une fièvre à 41 °C et la persistance de deux adénopathies latéro-cervicales droites, alors que toutes les autres adénopathies ont fondu sous chimiothérapie. La radiographie thoracique a montré des micronodules disséminés dans les deux champs pulmonaires, l’échographie abdominale a montré de multiples nodules siégeant au niveau rénal et splénique. L’administration d’une bi antibiothérapie à large spectre associée secondairement à des antifongiques n’a pas permis de mettre le malade en apyrexie. Vu le contexte clinique, la non amélioration du syndrome infectieux sous biantibiothérapie à large spectre et antifongique, la persistance des adénopathies et l’aspect radiologique ; le diagnostic de la tuberculose multifocale a été évoqué. La recherche de BK dans les expectorations est négative, la biopsie ganglionnaire ne pouvait pas se faire vue l’aplasie médullaire post chimiothérapie. Le patient a été alors mis sous traitement anti bacillaire selon le régime 2RHZEb/7RH. Le diagnostic de tuberculose a été secondairement confirmé par la biopsie d’une des adénopathies cervicales après la sorite de l’aplasie médullaire post chimiothérapie. Le patient est en rémission complète de sa leucémie aigue, l’évolution clinique et radiologique est bonne sous traitement anti bacillaire. Ainsi la tuberculose doit rester présente à l’esprit des cliniciens et doit être évoquée devant des adénopathies même si le contexte clinique n’est pas toujours très évocateur et les moyens diagnostics limités. 111 PO-39 ACUTE CARDIOTOXICITY OF THE ANTHRACYCLINE, ABOUT 2 CASES Yachekour. T1, Aberkane.M1, Bensmaine. M.A1, Boussadia.D1, Baroudi.N1, Zouani.S1, Taibi.K1, Touhami.H1, Baazi.M2, Messameh.M2, Hammou.L2 Sc hématology CHU Oran1 Sc cardiology CHU Oran1 Introduction: The anthracyclines are inhibitors of topo-isomérase II with a broad spectrum of anti tumoral activity, but their regulation is limited by their cardiotoxicity which exists in three forms: acute, subacute and chronic. Chronic toxicity depends on the serum peak of concentration and of the accumulated dose of the anthracycline while acute toxicity is rare, an early and adequate assumption of responsibility preserves the vital prognosis. We report 2 cases of them. Patients and methods: Case N° 1: H/A.H, 16 years old known since July 2008, for LAL T, the cardiac echography of the assessment pretherapeutic finds a VG not dilated of good total and segmentary systolic function, ejection fraction: 68%, not of dilation of the cardiac cavities, not of anomaly of the mitral and aortic structures. Induction by the protocol GRAALL 94, J1 the 7/12/08. The anthracyclines used is the doxorubicin with the amount of 30 mg/m2, 1day day2 day3 day15 day16 (total amount 25O mg), with J 50 of induction a total cardiac failure was noted with a HTAP and a reduction in the fraction of ejection to 30%, put under diuretic, cardiotonic, IEC. a total recovery of the noted cardiac function two months. Curently the patient is in complete remission. Case N°2: F/B.F 26 years since November 2009, for LAM and hepatitis B. the cardiac echography into pre therapeutic finds a VG not dilated with EF: 64%. The protocol of induction of the CR is Rubidomycine-Aracytine whose J1 was managed 19 /11/09. After a total amount of 210 mg of Rubidomycine a table of total cardiac failure with EF: 20% with a general deterioration of the state. The patient was put under cardiotonic, IEC, diuretic. 26 days of intensive treatments, with cooperation of the cardiologists, a total recovery of the cardiac function after. The fraction of ejection went back to 57%. The patient is currently in therapeutic failure of sound. Discussion: During acute cardiotoxicity of the anthracyclines, cardiac echography very often reveals a reduction in the ventricular fraction of ejection. The myocardic biopsy is the only specific test making it possible precociously to diagnose this toxicity induced by the anthracyclines. This cardiac toxicity can be decreased thanks to modifications in the methods of administration of the anthracycline, thanks to the use of cardioprotecteurs. The preference of derived from the doxorubicine having a reduced cardiotoxicity, as the anthracyclines liposomales would be another solution. 112 PO-40 SAFETY OF FLUDARABINE, CYCLOPHOSPHAMIDE AND RITUXIMAB REGIMEN IN CHRONIC LYMPHOCYTIC LEUKEMIA: ABOUT 68 COURSES: A SINGLE CENTER EXPERIENCE Kacem K, Massmoudi S, Ben Lakhal R, Manaï Z, Bouteraa W, Aissaoui L, Ben Abdennebi Y, Ben Amor R, Jeddi R, Bel Hadj Ali Z, Ben Abid H, Meddeb B. Haematology Department of AZIZA OTHMANA Hospital, Tunisia Recent advances in the management of chronic lymphocytic Leukemia (CLL) have seen the development of highly effective regimens capable of producing complete remissions. The CLL 8 trial showed the superiority of R-FC with no increase in the toxicity in comparison of FC regimen. We report our experience with R-FC combination. A total of 68 cycles were assessable for toxicity. Between March 2008 and January 2010, 68 courses of R-FC have been done for 14 patients with CLL in haematology department of AZIZA OTHMANA Hospital. The R-FC regimen consisted of Fludarabine 30 mg/m2/day orally on days 1-5; Cyclophosphamide 200mg/m2/ day orally on days 1-5 and Rituximab375 mg/m2/day on the first cycle then at 500mg/m2/day for cycle 2 to 6. This course was repeated monthly for up to 6 cycles. Antimicrobial prophylaxis comprised trimethoprim/sulfamethoxazole and acyclovir. G-CSF is prescribed if the rate of PNN< 500/mm3. The median age was 58 years (range 28-64), 13/14 were male, 8/14 patients were in Binet stage C and 6/14 patients were in Binet stage B with a progression disease as defined by the National Cancer Institute sponsored working group (NCI-WG) 1996 criteria. Cytogenetic abnormalities were found in 55%. Grade III/IV neutropenia episodes were observed in 54.4% of cycles. However, only 13.5% of minor infections (fever of unknown origin) were notified. Thrombocytopenia episodes were observed in 14.7% of cycles and were all of grade I/II. Gastro intestinal toxicity was limited to grade II/III with nausea/vomiting in 19.1% leading to discontinue the treatment in 6 patients on day 4. Prophylactic ondansetron was administered to all patients. Grade II/III mucositis was present in 4.4 % of cycles. One patient died within 3 months of starting therapy (after 2 courses of R-FC). He showed a reactivation of B virus hepatitis with gastro intestinal bleeding. Another patient showed a reactivation of B virus hepatitis 15 days after the end of the 6th cycle. Among the nine patients assessable for the response, eight are in complete response (RC). The 4 others are not yet evaluated. Richter syndrome (Hodgkin lymphoma) occurred in one patient at 11 months after RC. There was no statistically significant association between adverse events and pre-treatment characteristics such as age, stage of CLL, initial lymphocytosis and lymphopenia. The incidence of neutropenia is mostly observed in the fourth cycle. R-FC regimen is well tolerated as published in large studies. 113 PO-41 CHRONIC MYELOID LEUKEMIA IN CENTRAL TUNISIA Ben Youssef Y,Zaier M, Bouallegue S, Ben Fredj W, Regaieg H, Achour B, Khelif A. Hematology Clinic. Farhat Hached Hospital. Susah. Tunisia Objectives: To determine the clinical, hematological and cytogenetic characteristics at diagnosis in CML patients. To evaluate the hematologic, cytogenetic and molecular responses of CML patients treated with imatinib mesylate. Design: Records of 43 patients diagnosed with CML between January 2000 and December 2009 were retrospectively analyzed. Setting: Hematology Clinic at Farhat Hached teaching Hospital. Methods: The daily dose of Imatinib was 400 mg. Serial quantitative PCR assays were performed at Pasteur institute, Tunis, using Taq-man technology. Results: The median age was 40 years (05 – 71). Gender: 18 male, 25 female. Sex ratio: 0,72. Ninety percent of the patients presented to the hematology clinic within 6 months of the onset of the symptoms. Splenomegaly and weight loss were the most frequent presenting features. CML was discovered incidentally in 7 patients. The Sokal risk was low in 25, 5 %, intermediate in 51 % and high in 23, 5 %. The Ph chromosome was found in 42/43 patients. In the Ph negative case, the CML diagnosis was made on the presence of bcr-abl transcript. Additional cytogenetic abnormalities were observed in 6 cases. The median time between dia5gnosis and treatment initiation with Imatinib was 8 months (150 months). Adverse events were noted in 11/43 patients. Complete hematologic remission rate was 97,7%. Complete cytogenetic remission at 6 months was 70 %. Major molecular response at 18 months, evaluated by Real-time PCR, was 60 %. Two patients have progressed to accelerated phase/blastic crisis, despite Imatinib dose escalating. Five patients were subsequently treated with second generation TKI. Conclusion Hematologic, cytogenetic and molecular responses in our series appear to be comparable with western experience. 114 PO-42 CONTRIBUTION OF REAL TIME PCR IN THE MONITORING OF RESIDUAL DISEASE IN CML PATIENTS Gabsi N; Menif S.;Msaddek F.;Elloumi M.;Ben ABID H.;Belakhal R.; Ben Romdhane N.; Laatiri A.;Khelif A.;Meddeb B. Hematology Department Pasteur Institut, Hematology department Aziza Othmana Hospital Hematology Department Farhat Hached Hospital, Hematology Department Hedi Chaker Hospital Hematology Department Rabta Hospital Introduction: Chronic myeloid leukemia (CML) is a myeloproliferatif disorder (MPD) characterized by a specific molecular hallmark: Bcr-Abl fusion gene. The introduction of Imatinib, the first tyrosine kinase, in the last decade has revolutionized the prognosis of CML. Since several trials have demonstrated the importance of the residual disease as prognosis factor in patients with CML receiving Imatinib, researches have been trying so hard to improve therapy with aim of obtaining a minimal residual disease at the molecular level. So that, Quantitative Real Time-PCR assays which is by far the most sensitive assay in this context has been used for the quantification of Bcr-Abl transcript level in the peripheral blood. The target of this study is to underline the place of rigorous molecular monitoring in the management of the residual disease to predict a subsequent relapse by Quantitative Real-Time PCR. Patients & methods: We conducted a retrospective study in which 93 patients (50 males and 43 females) with chronic myeloid leukemia in the chronic phase who had been undergoing treatment with Imatinib (400 mg/day) and had been monitored with real-time quantitative PCR had been included. All patients were BCR-ABL1-positive and Ph-chromosome-positive at diagnosis. The median age at diagnosis was 42 years (6-72 years). The median follow-up after beginning treatment was 42 months (24–96). A total of 591 samples of peripheral blood were analyzed. The median of samples test was 6 samples from each patient during the course of the disease (4- 15 samples). Each sample was processed the same day of collection in optimal condition including RNA extraction, RNA retrotranscription (using Random hexmers), Real-Time Quantitative PCR (using TaqMan probe). Absolute copy numbers of Bcr-Abl transcripts are expressed as a ratio to the absolute copy numbers of the control gene “Abl” transcripts. Analysis was based on a major molecular response (MMolR) which corresponds to a BCR-ABL/ABL ratio ≤ 0.1%. 115 Results: The mean value of Abl transcripts was 12000 copy numbers. The R-T Q PCR data in the first 18 months divide patients into 2 groups: - The first group has a continuous decrease of the ratio until MMolR or undetectable Bcr-Abl transcripts level - the second group keeps high load of tumor cells with constant or upward ratio The MMolR or undetectable Bcr-Abl transcripts was obtained in 67% of our patients at one moment of the evolution. Two third of patients in MMolR (45%) have maintained the response so far for a median period of 25.5 months up to the last samples included in this study. However, 22% of these patients who were in MMolR have lost it, although a cytogenetic remission. Patients who belong to the second group were 33%: the BCR-ABL/ABL ratio ranges between 0.9% and 25% and they have never been in MMolR with a median follow-up of 42 months. Discussion & conclusion: The molecular kinetics of residual disease has become one of the most substantial components in the monitoring of patient with CML in the Imatinib era. Since, the recognition of relapse at the molecular level allows therapeutic intervention while the burden of disease is still relatively low. Those results show that rising or persistently high levels of Bcr-Abl mRNA can be detected although cytogenetic or hematological remission showing that conventional analysis offers only limited information, whereas Quantitative RT-PCR assay can detect a single leukemia cell in a background of 104 -105 normal cells. Indeed, after treatment by Imatinib, serial Quantitative RTPCR analysis of peripheral blood specimens can effectively distinguish those patients who are destined to remain in remission as longer as possible from those who are destined to relapse although a cytogenetic remission. That is to say, R-T Quantitative PCR is a reliable and sensitive technique which can predict long term stability of the disease and pattern of response. 116 PO-43 JAK2 MUTATION IN TUNISIAN PATIENTS WITH MYELOPROLIFERATIVE NEOPLASMS S. Boukhris; H. Khemakhem; H. Regaieg; L. Ifa; H. Hmida; S. Hadhri; H. Skouri Laboratoire Hématologie et Banque du Sang – CHU Sahloul Sousse Tunisie Background: JAK2 V617F is an acquired mutation present in a considerable proportion of patients with myeloproliferative neoplasms (MPN) and thromboembolic diseases. Aim: We aimed to determine the prevalence of the JAK2 V617F mutation in Tunisian patients with MPN. Methods: We retrospectively analyzed our lab’s registry data and medical records concerning patients with MPN, since February 2007 to February 2010. The JAK2 V617F was assessed by means of nested PCR SSP which has a sensibility of 2% for mutant allele. Results: During 3 years, 274 patients with MPN were included: Polycythemia Vera (PV) (n=134), thrombocytemia essential (TE) (n=101), chronic myeloproliferatif leukaemia (CML) (n=25), chronic idiopathic myelofibrose (CIM) (n=14). The JAK2 mutation was detected in 33.2% (91/274) patients. Sex and age seem to be correlated to the JAK2 mutation: females were more likely than males to have JAK2 mutation (P=0.0001; OR=2.76); JAK2 mutated patients were older (P=0.017 ; OR=1.86). Conclusions: The prevalence of JAK2 V617F mutations in Tunisian patients with MPN was 33.2%. Further studies with quantification of JAK2 mutation load will be help for therapy monitoring. 117 PO-44 MYELOPROLIFERATIVES SYNDROMES IN CHILDHOOD 6 CASES REPORT I.Ben amor1, M.Mdhaffar1 , S.Hdiji1, Ch. Kallel2, S.Mnif3, H.Sennena4, S.Makni 5, A.Saad4, T.Boudawara5, M.Elloumi1 1:Service hématologie, Sfax, 2: laboratoire d’hématologie, Sfax, 3: laboratoire d’hématologie, institue pasteur, Tunis, 4: laboratoire de cytoénétique, Sousse, 5: laboratoire d’anatomopathologie, Sfax Introduction: Myeloproliferative syndromes (MPS) affected specially adult older than 60 years. There are rare in children. We report 6 childhood cases of MPS, we detail the diagnostic criteria and therapeutics features. Materiel and Methods: Patients collected are aged 5to 20 years old. Two male patients had chronic myelogenous leukemia (CML), three female patients had an essential thrombocythemia (ET), and one male patient had idiopathic myelofibrosis (IMF). The investigations contain a hemogramme, a bone marrow aspiration, a bone marrow biopsy, a karyotype, and a molecular biology to study the bcrabl rearrangement and the Jak2 mutation. We have excluded the secondary causes of thrombocytosis. For these patients we detailed the therapeutics and evolutives features. Results: Two patients aged 13 years had a CML. The first was in chronic phase and the second in accelerated phase. The two patients hadn’t a HLA histocompatible donor. The treatment was imatinib, 400mg daily for the patient in chronic phase who had a complete cytogenetic response and major molecular response in 40 months of follow-up. The other patient in accelerated phase received 600mg/day then 800mg/day with failure and evolution to the blast crisis. Three patients aged of 5, 9, and 19 years had an ET with a negative Jak2 mutation. Hydroxyurée was administered with an anti platelet aggregation treatment (aspegic) allowing to reduce the platelet count<600.000 without bleeding or thrombosis complications. One patient had IMF was treated by corticotherapy at the dose of 0, 5 mg/ kg with transient responses. Conclusion: The MPS is a rare entity in childhood, whose diagnostic criteria are similar to adults. However they present therapeutic problems: the place of allogeneic stem-cell transplantation, the duration of treatment and the toxicity of some medicines: teratogenesis of the hydroxyurée, very long treatment with imatinib. 118 PO-45 HLA-DR AND CD34 EXPRESSION IN 339 CASES OF MYELOÏD ACUTE LEUKEMIA Jaouadi L. Ben Salah N. Gouider E. Siala R. El Borgi W.Ben Lakhal F. Hafsia R. Laboratoire d’Hématologie Biologique de L’Hôpital Aziza Othmana Introduction: Immunophenotyping is a widely used method, complementing morphology, cytochemistry and karyotype study to make diagnosis and classification of acute myeloid leukemia (AML). The objective of this study is to evaluate the expression of HLA-DR and CD34 in myeloid non promyelocytic AML diagnosed in the laboratory of hematology in Aziza Othmana hospital. Materials: From April 2005 to December 2009, 339 AML (APL excluded) were diagnosed. Immunophenotyping analysis of the bone marrow samples was performed by flow cytometry (cytometer Beckmann Coulter ® XL-MCL) using a large panel of monoclonal antibodies including myeloid, lymphoid and immaturity markers labeled with different fluorochromes. Results: The results of HLA-DR and CD34 expressions are resumed in the table below: Frequencies HLA-DR+ CD34+ 74,55% 56,88% HLA-DR+ CD34+ 47,9% HLADR+ CD3426,65% HLADRCD34+ 8,99% HLA-DRCD3416,46% Discussion: As reported in the literature, HLA-DR is expressed in the majority of AML non APL.CD34 is less frequently expressed. The absence of HLA DR and CD34 is known to be useful for distinguishing APL from other AML subtypes. In our study 16,46% of AML did not show neither HLA DR nor CD34.The review of literature, revealed that 9 to 19% of non APL AML lack these antigens. This study shows the large heterogeneity of immaturity markers in AML non APL. 119 PO-46 ANTIGEN EXPRESSION IN AML: RELATIONSHIP WITH PATIENT OUTCOME Ben Salah N, Souli N, Jaoubli M, Skhiri H,, Borji W, Ben Lakhal F, Jeddi R, Gouider E, Hafsia R. Laboratoire d’Hématologie Biologique de L’Hôpital Aziza Othmana Introduction: Acute myeloid leukemia (AML) involves the presence of a clonal expansion of neoplastic myeloid cells in the blood, bone marrow, and various tissues. Its represents a broad variety of distinct entities. Immunophenotyping is a widely used method to diagnose and classify acute leukemia. The objective of our study is to evaluate the contribution of Immunophenotyping in predicting patient outcome. Materials and Methods: Our study is retrospective (October 2005 - July 2007), it concerned 56 patients aged from 18 to 55 years and treated for de novo LAM of adult (AML 3 excluded).The immunophenotype was performed by flow cytometry (Beckman-Coulter XL MCL ®). We use a wide panel of antibodies including: Immaturity, Lymphoid B, T and myeloid markers. The diagnosis of AML is retained according to criteria of the European Group for the Immunological characterization of Leukemias (EGIL). Results: Out of 56 patients, 42(75%) achieved complete remission (CR) after remission induction therapy. None of the antigens tested except for the CD7 were associated with a higher or lower CR rate. The difference in complete remission between CD7+ patients (50%) and CD7- patients (85.4%) is statistically significant (P= 0,044). None of the antigens tested were associated with overall survival or with disease free survival. Discussion: The prognostic implication of the immunophenotype in AML remains controversial. Comparing results can be hampered by methodologies differences in the detection of antigen expression, patient populations studied and treatment regimens administered. The prognostic value of CD7 expression in AML is uncertain, several studies reports a poor response to induction chemotherapy among patients CD7+. 120 PO-47 STUDY OF ABERRANT ANTIGEN EXPRESSION IN ACUTE MYELOID LEUKEMIA (AML): ABOUT 370 CASES Ben Lakhal F, Ben Salah N, Gouider E, Mannougui I, Siala R, Borgi W, Hafsia R. Service d’Hématologie Biologique. Hopital Aziza Othmana. Tunis Immunophenotyping is a widely used method to diagnose and classify acute leukemia, thereby complementing morphology and cytochemistry. Aberrant antigen expression of T or B- cell lineage antigens can variably be detected on the leukemic cells of AML cases. From April 2005 to December 2009, 370 cases of AML were diagnosed in Aziza Othmana Hospital. Flow cytometry is performed on bone marrow blast cells using a Beckman Coulter XL MCL®. An aberrant expression of a lymphoid antigen was found in 17% of the cases. T lymphoid antigens were more expressed than B lymphoid antigens: 81% versus 35%. CD7 was the most frequently expressed (55,55%). CD2 was expressed in 17,46%, its association with the variant promyelocytic leukemia was found in 10% of the cases. CD19, cytoplasmic CD22, CD10 and CD8 were expressed in respectively 17%, 6%, 11% and 5%. The expression of cytoplasmic CD3 and CD5 was noted in one case respectively. CD1a and CD3 were not expressed in our study. Several studies reported an aberrant expression of lymphoid antigens in AML. Its biological and clinical significance are not clearly established. It reflects the heterogeneity of immunophenotyping of AML. 121 PO-48 THE OUTCOME OF CHILDREN WITH T(8,21) ACUTE MYELOID LEUKEMIA TREATED WITH CHEMOTHERAPY ALONE Aissaoui L, Ben Hassen I, Ben Abdennebi Y, Bouterâa W, Jeddi R, Ben Amor R, Kacem K, Ben LakhalR, Bel Hadj Ali Z, Ben Abid H, Meddeb B Department of Hematology. Aziza Othmana Hospital, Tunis-TUNISIA Introduction: The t(8,21) acute myeloid leukemia corresponds to one of the core binding factor acute myeloid leukemias(CBF-AML) characterized by the good outcome when treated with intensive chemotherapy with high-dose cytarabine and not considered as candidates for intensification with allogeneic stem cell transplantation in first complete remission. Patients and methods: Between January 2003 and December 2008, among 32 children with acute myeloid leukemia enrolled in department of Hematology of Aziza Othmana Hospital, 8(25%) t(8,21) were noted. We propose to study only patients treated with chemotherapy alone. Seven patients were enrolled. The median age was 12.5 years (10-15 years). The median WBC was 11.000/mm2 (2.20030.100). The diagnosis of AML was done by BM smears and immunophenotyping (CMF) using EGILE scoring. The t(8,21) was detected by conventional cytogenetic All patients were treated according to the French multicenter protocol ELAM02 with an anthracycline (mitoxantrone) and cytarabine –based induction followed by 3 courses of consolidation therapy among them 2 courses with high dose cytarabine. Results: Complete remission (CR) was achieved in all patients (100%). One toxic death occurred in the second course of consolidation. One relapse occurred 5 years of CR. The patient was allograft in CR2. OS (4years)=85.7% vs 59% in the other AML and EFS(4years)=71.4% vs 45.5% in the other AML. DFS(4 years)=83.3%. Discussion: Our results are similar to those of literature. Even, if we study the prognostic significance of Kit mutations which are implicated as a prognostic factor in adults, their presence does not provide rationale for alteration of therapy. 122 Conclusion: Patients with t(8,21) have been considered a favorable risk group than non t(8,21) AML given their superior OS and EFS and must be treated solely with chemotherapy even if a matched family donor is available because the hematopoietic stem cell transplantation does not improve neither the OS nor the EFS. 123 PO-49 TREATMENT OF CHILDHOOD ACUTE MYELOID LEUKEMIA IN TUNISIAN PATIENTS (EXPERIENCE OF 6 YEARS) Aissaoui L, Ben Hassen I, Ben Abdennebi Y, Jeddi R, Bouterâa W, Ben Amor R, Kacem K, Ben Lakhal R, Bel Hadj Ali Z, Ben Abid H, Meddeb B Department of Hematology. Aziza Othmana Hospital, Tunis-TUNISIA Introduction: Acute myeloid leukemia (AML) accounts for one fourth of the acute leukemia in children, but it is responsible for more than half of the leukemic deaths in this patient population. In contrast to the tremendous success in the treatment of acute lymphoblastic leukemia(ALL) in the last three decades, resulting in a >80% cure rate, improvements in AML therapy have been limited, and only about half of the patients with AML are cured of their disease. Patients and methods: Between January 2003 and December 2008, among 214 children acute leukemia enrolled in department of Hematology of Aziza Othmana Hospital, 32(15%) de novo AML were noted (Down’s syndrome and FAB M3 were excluded). The median age was 11.5 years (2.2-17 years). The median WBC was 16.500/mm3. Two (7.7%) patients have CNS disease. The diagnosis of AML was done by BM smears and immunophenotyping (CMF) using EGILE scoring. The distribution of FAB types: 10M1, 13M2, 3M4, 4M5, 1M6 and 1M7 Cytogenetic study was done in all patients and it was informative in 28 cases (87.5%). According to the Medical Research Council’s Trial (MRC): 9 patients (32%) were classified into favorable group or CBF leukemia, 18(64.5%) into intermediate group and only 1(3.5%) into unfavorable group. All patients were treated according to the French multicenter protocol ELAM 02 with an anthracycline (mitoxantrone) and cytarabine –based induction than 3 courses of consolidation therapy among them, 2 courses with high dose cytarabine. Patients in CR with a matched sibling donor were eligible for allogeneic stem cell transplantation. Children with CNS disease received twice weekly triple intrathecal therapy for 6 doses, then monthly until the end of therapy. Results: Complete remission (CR) was achieved in 28 patients (87.5%). Toxic death and induction failure were respectively 3% and 9.3%. Eighteen patients (64%) had a matching sibling donor of which 5 CBF-AML but stem transplantation was done only in 7(39%) because of problem of feasibility. Two of them died by GVHD but no relapse occurred in this group. Relapse occurred in 10 patients (35.7%) in median period of 9 months. OS (3years) and EFS(3years) were respectively 57.8% and 55% 124 Discussion: Cytogenetic has consistently been shown to carry major prognostic significance in AML and there were clear differences in the distribution of cytogenetic risk groups and the outcome. Despite of the low number of patients, our results seem to be near those reported in large studies. Conclusion: In childhood AML, patients with non- CBF AML having a matched family donor had to undergo allogeneic hematopoietic stem cell transplant in first CR to improve their OS and EFS. 125 PO-50 DE NOVO CHILDHOOD ACUTE MYELOID LEUKAEMIA: ABOUT 54 CASES O.

They remain of bad prognosis, in spite of intensive therapeutic protocols. We study here the diagnostic and therapeutic aspects of children de novo AML in a personal series. Patients and methods: This is a retrospective study including 54 children (age<=16years) affected by de novo AML between 1996 and 2009 followed in Sfax hospital. Diagnosis has been established according to FAB classification. We analyze here epidemiological characteristic and diagnostic (clinic, biology) of these patients. Results: The series included 31girls and 23 boys (SexRatio=0.64). The median age was of 11 years. Splenomegaly and adenopathies were noted in 57%.only one patient had a meningal infiltration in the diagnosis.The median of WBC count at diagnosis was 52000/mm3 and hyperleucocytosis more than 50000/mm3 was noted in 28% of the patients.We noted anemia in all patients;the median count of platelet was 56000/mm3 and sever thrombopenia (platelet<50000/ mm3)was noted in74%.Distribution according FAB classification was: 13%of AML1; 22%of AML2;13% of AML3;11% of AML4; 24%ofAML5 ;4%of AML6 and 13% unclassified. Cytogenetic of bone marrow cells showed chromosomal abnormalities in24% of cases; only 7% of patients had favourable abnormalities. Conclusion: Epidemiologic aspects of our patients showed more girls affected by leukemia than boy unlike to the literature results.The most frequent reason of consultation is anemia.The frequency of Tumoral syndrome (57%),the results of hemogram noted in our study are similar than rapported. The results of distribution according FAB classification is different from those found in the literature showing more frequency of type2(22%)and type5(24%). However, for cytogenetic results, the most of our karyotype is normal (74%) and this is not the case in the literature in which more than 90% show chromosomal abnormalities. 126 PO-51 EFFICACY OF IMATINIB IN CHRONIC MYELOID LEUKEMIA ACUTE PHASE: ABOUT 3 CASES H. Zidani; Y.Ouarhlent ; K. Kouidri; N. Kara Mostefa; R. Chafai; M. Saïdi Haematology, University Hospital of Batna. Introduction: If the treatment of chronic myeloid leukemia (CML) in chronic phase has been revolutionized by the use of an inhibitor of tyrosine kinase: imatinib mesylate, one of the more acute phase(AcP) is deploring and prognosis. There is no well defined protocol, but treatment for the type of acutisation (ALL or AML) is often attempted in order to restore a phase myeloid and propose a possible allograft. We report three cases of acute phase in which different conventional chemotherapy were tried without success, but who responded to imatinib (IM) dose of 600mg/ day. Observations: The first case: man 40 years old, with CML since September 2001treated by Hydrea*. An acutisation is diagnosed in November 2008, chemotherapy was attempted without success (Rubidomycine: 45mg/m2 / Aracytine 100mg/m2 day 1 and during 5 days).The patient is put under IM 600mg / d, after 20 days, a clear objective improved clinical status, regression of splenomegaly with reduced leukocytosis.Eighty days after treatment the patient is in complete hematological remission(CHR).He is alive 16 months after AcP and September months of IM. The second case: a woman 39 years old, with CML since July 2007. In June 2009, she presents a poor condition, splenomegaly (DS: 15cm) and AcP which 17% of myeloblasts in blood and 23% in bone marrow.Treated by IM 600mg/d. At d45, she presents in complete haematological remission. She is alive for 8 months. HLA typing is not found in HLA The third case: man, 56 years, with CML since June 2009 put on Hydrea. An AcP in February 2010with a splenomegaly (DS: 17cm), complete blood count showed leukocytosis has 70500/ mm3, Hb: 6.1 g / dl, PLQ: 35000/mm3, a 34% blood blasts and 41% in marrow. We have started IM 600mg / d, an improvement of clinical status and normalization of blood counts and blood smear is obtained at d18. Comments: It should be noted that these patients did not receive IM in chronic phase, which may explain this sensitivity. The more acute phase of CML is certainly the most often resistant to conventional chemotherapy regimens, these findings demonstrate that high-dose IM is an interesting alternative but surely transient (insufficient decline in these two patients) hence the need to consider an allograft. 127 PO-52 ASSESSMENT OF A CYTOLOGY DIAGNOSIS UNIT N.Kara Mostefa1; H.Otmani 1; FZ. Neche 1; H.Zidani2 ;K. Kouidri2; M. Saidi2 1.Laboratory of Hematology; 2. Hematology,University Hospital, Batna,Algeria. Introduction: In practice, the cytology diagnosis is an indispensable part in hematology and remains (despite new technology) of a certain contribution should not be overlooked. It will benefit from being developed and supplemented by tests such as flow cytometry and cytogenetics.Convinced of this importance, we have reinforced this activity: - Centralizing the blades in laboratory hematology. - Affecting the specialized personnel: hematologists and Hemobiologists. - Putting in place specific staining. Materials and methods: This is a retrospective study of 2009 (January 1 to December 31) in which we have collected and listed the activity of this unity. The sampling comes from clinical services: hematology, pediatrics, internal medicine,intensive care unit, infectious diseases, pneumo-phtisiology, maternity. They are: peripheral blood smear, bone marrow puncture,bone marrow, nodal puncture aspiration, cytology of effusion fluids. The cytochemical stains like sudan black, peroxydase and perls are also performed. Results: We analyzed 447 blood and marrow smears stained with MGG: 293 Hematology, 95 pediatrics, internal medicine 40, and 19 other services that have laid the following diagnosis: megaloblastic anemia: 75 cases,acute leukemia: 54, multiple myeloma: 30, lymphoproliferative disease: 12,chronoic myeloîde leukemia (CML): 12, CML in blast crisis: 03, myelodysplastic syndrome: 04, invasion by a large cell lymphoma: 07, bone marrow metastasis (adenocarcinoma of the prostate): 01, bone marrow localization of Hodgkin’s disease: 01,hemophagocytic syndrome: 02, visceral leishmaniasis: 02 cases. The diagnosis of acute leukemia is complemented by cytochemical staining: peroxidases: 28 (17 positive and 11 negative) or sudan black: 15 (06 positive cases and 09 negative cases) who have distinguished: 34 AML and 20 ALL. Perls staining was performed on 04 medullogram suspected myelodysplasia. The study product of ganglionic puncture aspiration: 41 samples from the hematology service that helped guide the diagnosis of Hodgkin disease 06, 09 large-cell 128 NHL, 03 lymphoblastic NHL, infiltration by small mature lymphocytes in 15 samples, 02 of hemophagocytic syndrome, a metastatic lymphadenitis. Comments / Conclusion: This work aims to identify various diseases diagnosed by cytological studies alone that remains a cornerstone diagnostic biological hematology. It highlights the role of cytochemical staining in the diagnosis of acute leukemia in the absence of immunophenotype but also the vital interest of the latter in cases where non-obvious and cytochemical stains were negative (LAM0,LAL biphenotypic..).The nodal puncture aspiration must be systematic in any chronic lymphadenopathy, which allowed us to compare the cytology and pathology. 129 PO-53 HAEMATOLOGICAL MALIGNANCIES: INCIDENCE IN BATNA FOR 2003-2007 A.Bouhidel1; ML.Bouhidel1; M.Saïdi2; Y.Ouarhlent2; H.Bouncer1. 1. Epidemiology department,University Hospital, Batna, Algeria 2. Hematology department, University Hospital, Batna, Algeria. The aim of this study is to present the incidence of the hematological malignancies (HM) in the department of Batna (Middle East Algeria). We extracted the data from the “Registre du Cancer de la Wilaya de Batna” created in 1995. This department has 1.120 000 persons. The HM diseases were coded using the third edition of the International Classification of Oncologic diseases (CIM.O). Three hundred sixty new cases (327 adults and 33children) HM were registered over the period 2003-2007 and 2780 cancers in the same time, so the MH represents 13% of all cancers. The most frequent HM are: the Non-Hodgkin’s malignant lymphomas (NHML): 114 cases, followed by acute leukemia: 98 cases(61AML, 27ALL), Hodgkin’s lymphomas (HL): 65 cases and the multiple myeloma in the fourth position with 41 cases. The others are: chronic lymphocytic leukemia (CLL) 18pts, chronic myeloid leukemia (CML): 16 cases and 6 polycythemia Vera. In children less than 15years, the MH represent 30% of all cancers, the annual incidence is 0.7/105 children. Conclusion. The MH represents 13% of cancers in adults and 30% in children. The NHML are the first cause of HM in adults quite as other cancer registries. For more and appropriate information a HM registry has to be created. 130 PO-54 ASSOCIATION OF SOLID TUMORS AND CHRONIC MYELOID LEUKEMIA C. Kerar, M. Ramaoun, L. Louanchi, H. Terfaia, H. Ahmidatou, L. Bouriche, M. Belhani Hematology department Beni-Messous hospital Algeries, Algeria Introduction Among risk factors of solid tumors and blood cancer (chronic myeloid leukemia), we incriminate the benzene and ionizing radiation, in addition, the treatment of chronic myeloid leukemia increases this risk (alkylating agents, inhibitors of tyrosine kinase). We report 3 cases of chronic myeloid leukemia associated with cancers. 120 cases of chronic myeloid leukemia, were retrospectively analyzed during 10 years, we found 3 associations of chronic myeloid leukemia and cancers (solid tumors). 1st patient: a woman of 83 year-old, she underwent a gastrectomy for gastric carcinoma without chemotherapy, she develops 17 years later a chronic myeloid leukemia. 2nd patient: a woman who is 62 year-old, she underwent a mastectomy alone for breast cancer, 30 years ago. She presented with diffuse bone pain and splenomegaly. Full blood count showed a leukocytosis, a bone scintigraphy showed increased concentration of the tracer in some region but tumor markers were negative, bcr-abl fusion gene was found in PCR. 3rd patient: a man of 50 years old at diagnosis, exposed to ionizing radiations, presented with splenomegaly, leukocytosis and 20% of myeloid cells in blood smear, the diagnosis of chronic myeloid leukemia was made. He was given hydroyurea, purinethol and imatinib. Seven years later, he develops an endothelial bladder cancer. Discussion: In the first two cases, the occurrence of chronic myeloid leukemia was at a distance from the neoplasm, without chemotherapy or radiotherapy (surgery alone). Isn’t it en relationship with a particular terrain? In the third case, the patient was accidentally exposed to ionizing radiations and treated for his chronic myeloid leukemia(alkylating agents, inhibitors of thyrosine kinase), beside the radiations, treatment can also be incriminated in the genesis of the tumor. Conclusion: Many factors can be incriminated in the oncogenesis of solid tumors during myeloproliferative syndromes related to environmental, viral, genetic factors or linked to there own treatment. 131 PO-55 RARE ASSOCIATION: RECKLINGHAUSEN’S DISEASE AND ACUTE LEUKAEMIA C. Kerar, M. Ramaoun, L. Louanchi, H. Terfaia, H. Ahmidatou, L. Bouriche, M. Belhani Hematology department Beni-Messous hospital Algeries, Algeria Introduction: Neurofibromatosis type 1(Recklinghausen’s disease) is an autonomic dominant disorder; its annual incidence at birth is 1 per 3500. Neurofibromatosis gene acts like a suppressant; the consequence of its mutation is the activation of corresponding oncogene. It’s an inherited disease predisposing for a wide variety of malignant haematological pathologies (juvenile myelomonocytic leukaemia, chronic myelomonocytic leukaemia, monosomy 7 associated with myeloproliferatif syndrome). It develops early in childhood, adult form is very rare, and one case of acute myeloid leukaemia was reported. Methods: We report a case of a woman who’s 62 year-old, she was diagnosed with neurofibromatosis when she was 20 year-old, she presented with a few weeks history of asthenia and pallor, on examination, there were a lot of neurofibroma on her skin and a splenomegaly. The full blood count showed a leukocytosis with anaemia and thrombocytopenia. Blood smear and bone marrow aspiration cytology returned in favour of acute myeloid leukaemia. We gave her a symptomatic treatment associated with low dose chemotherapy (cytarabine). After 6 months treatment, we achieved a complete remission: normalization of full blood count and undetectable level of leukaemic blasts. Conclusion: Neurofibromatosis is a rare disease, it’s important to evoke its association with an acute leukaemia in front of haematological manifestations. 132 PO-56 CLINICAL AND BIOLOGICAL CHARACTERISTICS OF ADULT BIPHENOTIPIC ACUTE LEUKEMIA (BAL): A SERIES OF 45 ALGERIAN PATIENTS A.Talbi; F.Harièche; N.Ait Amer; F.Tensaout; M.Benakli; S.Akhrouf; F.Boumansour; F.Zerhouni; R.M.Hamladji Departement of haematology and BMT unit, Pierre and Marie Curie, Algiers; Algeria Background: BAL display features of both myeloid and lymphoid lineage. It is rare, actually well diagnose thanks to the immunophenotype. We present here the clinical and the biological characteristics and the out come of BAL in our experience. Design and Methods: We analysed 45 adult BAL patients (pts),diagnosed between January 2002 and December 2009 according to the European group for the Immunological characterization of leukemia (EGIL), among 429 adult acute leukemia pts diagnosed according to FAB classification. Results: During the period of 7 years, of 452 acute leukemia pts, 45 cases of BAL were diagnosed in our unit (10,4%), among them 33 (73,7%) were B lymphoid and myeloid (B/M), and 12 (26,6%) were T lymphoid and myeloid (T/M), no case of B/T or trilineage differenciation. The median age is 27 years old (15-81), the sex ratio is 1,6 (28 M/17 F). The median count of white cells, hemoglobin and platelet is respectively 30, 9 (1,1 - 239) x 109/L, 81 (44-159)/L and 64 (9 – 477)/L, respectively. The median prevalence of blast in bone marrow was 94% (27 -100). Nine patients (20%) have extra medullary infiltration, which most commonly affect the mediastinum, the central nervous system was affected in 4pts(8,8%).Lymph nodes was affected in 18pts (40%), spleen in 13pts (28,8%) and both in 11pts(24,4%). The incidence of CD34 antigen expression were 73,3%; 58,3% of them were T/M. Above Fifty patients who has a genetic profil, 3 has t (9-22), 2pts has t(8-21), and 1 a SIL- TAL transcript. The induction regimen was Vincristin, Daunorubicin and L Asparaginase in 42 pts (97,6%) with negative myeloperoxydase coloration, and Daunorubicine – Cytarabine in 3 pts (6,9%) with positive ones, 2 pts do not have any treatment. The complete remission rate was 81,5%.The median follow up is 5 years, twenty(44,4%) patients are still alive, 2 are in relapse, 25pts died (55,5%),2 before treatement,7 pts after relapse (16,2%), 7 are refractory (16,2%), 4pts(9,3%) in complete remission and 5 pts (11%) during the induction. The overall survival is 28.8% and the disease free survival is 26.6%. Conclusion: The prognostic of BAL pts is poor. They showed a higher extra medullary infiltration, relapse and resistance to therapy after relapse. In our series the rate of death in complete remission is still too high, because of the remoteness of sanitary structure inducing late treatment of some infectious problems. 133 PO-57 STEM CELL TRANSPLANTATION Aaml Ali Alayeb, Faculty of Medicine / Surman The stem cell transplantation (SCT) represents the most active form of cancer therapy. The advances in the transplant technology and the differentiation with the availability of stem cells and supportive care not only have resulted in improved outcomes but also expanded the transplant options. The variety of stem cells have been extensively studied, and the strategies are being proposed for treating massive cancers However post transplant relapse and transplant related mortality remain the main causes of failure of this therapeutic approach. This study is going on to focus on the recent progress that leads to enhance the treatment by this approach and their applications in various kinds of diseases. 134 PO-58 GRANULOCYTIC SARCOMA, MYELOBLASTOMA {EXTRAMEDULLARY ACUTE MYELOID LEUKEMIA OR CHLOROMA}.A CASE REPORT Najah Abdulnabe Omer African Oncology Institute, Sabratha, Libya Background: Acute Myeloid leukemia (AML) is a malignant tumor of hematopoitic precursor cells of non lymphoid lineage arising in the bone marrow. Chloroma is an extramedullary acute myelogeneous leukemia, that occur in 2 -14% of cases. It is a localized tumor seen at diagnosis of AML or very rarely preceeding diagnosis and soon or later(within weeks to months average 7 months) patient develops AML, and most cases develops (t 8:21). Common sites reported in literature are orbit and paranasal sinuses, It can also involve bone, periosteum, soft tissues, lymph nodes and skin. In most cases, diagnosis is missed and diagnosed as diffuse large B- cell lymphoma if there are no blasts in the peripheral blood or bone marrow. The diagnosis is made if Auer Rods are detected or if myeloid origin is confirmed by cytochemical or immunohistochemical methods. Chloroma is Radiosensitive but systemic chemotherapy as for AML is indicated in most cases. Case Report: A 50-years-old Libyan female transferred to African oncology institute (AOI) as a case of Rhabdomyosarcoma. She presented with big gluteal mass progressively increase in size & MRI showed big subcutaneous mass. Second H/P opinion done in AOI and diagnosed as a case of lymphoblastic lymphoma (without immune stain of complete panel). We sent slides for 3d opinion to Germany and diagnosed by morphology and immune stain as a case of Chloroma or Extramedullary AML. Immune stains result showed: expression of CD43 (which favours of tumor of the hematopoietic origin and exclude sarcoma), expression of CD 34,CD33 and absence of lymphatic antigen is typical for AML. Workup (PBF, BMA & BMB) showed no blasts in the peripheral blood or bone marrow. Patient treated by induction of remission two cycles 3+7 protocol, she tolerated chemo well,and clinically patient improved dramatically regarding the pain and she could sit which she could not before, she planned for re-evaluation by MRI, if achieves complete remission she is for consolidation by HAM protocol. 135 PO-59 ACUTE MYELOBLASTIC LEUKEMIA PRESENTING AS MARROW HYPOPLASIA M.Benlazar, A.Hadjeb, A.El Mestari, N.Zemri, K.Tayebi, N.Siali, R.Messaoudi, Z.Zouaoui. Hematology unit, Hospital of Sidi Bel Abbés, ALGERIA. Introduction: In rare cases, transient marrow hypoplasia can precede acute myeloid leukemia. This episode is defined as a ‘preleukemic state’ which ineluctably leads a frankly leukemic phase. Case report: We report a case of a forty eight years old woman who had an episode of marrow suppression in June 2008 and which evolved six months after to an acute myeloid leukemia. The first episode of marrow hypoplasia was resolved after transfusion and antibiotic therapy the underlying infection. The bone marrow biopsy showed aplastic histological features without fibrosis and no blasts was detected. In July, the patient was asymptomatic and her blood count was normal. In October 2008, the patient presented a second episode of severe pancytopenia with pallor and fatigue, fever and pneumonia. The bone marrow examination showed 92% of myeloblasts, and the diagnosis of acute myeloid leukemia FAB1 by flow cytometry. The patient received induction chemotherapy (aracyitine and daunorubicin, 3+7 standard regimen) and achieved a complete remission. Conclusion, Patients with marrow hypoplasia carried a risk for subsequent development of acute myeloid leukemia, and the relation between the two affections is not clear. In these cases, the medical surveillance is of a great importance. 136 PO-60 TYROINE KINASE INHIBITOR (TKI)IMATINIB MESYLATE (GLIVEC) IS EFFECTIVE IN ALL PHASES OF CML GLIVEC BLOCK BCRL ABL EXPRESSION AND CAN INDUCE HAEMATOLOGICAL AND CYTOGENETIC REMISSION AND THE INTRODUCTION OF THESE SPECIFIC TYROSINE KINASE INHIBITION CHANGE ATTITMCTES OF THE THERAPY OF CML Rabia Omar Nafo Benghazi ABSTRACT Aim: Aim of the study: to assess treatment response of CML patients to imatinib meslate Methods: A total 59 patients with Philadelphia positive CML were treated with imatinib (glivec at dose 400mg). Fifty patients were in chronic phase and 9 patients were in accelerated phase. Patients were followed up at haematology clinic and evaluated for haematological and cytogenetic remission. Results: Fifty patients out of 59 patients were in chronic phase of CML. Eight patients in chronic phase achieved complete haematological and cytogenetic remission and 5 patients achieved complete haematological remission and partial cytogenetic remission and 2 patients achieved haematological and major cytogenetic remission. Patients achieved complete haematological remission only 30, and 6 patients achieved no haematological or cytogenetic remission. Nine patients were in accelerated phase. Two patients achieved hematological and cytogenetic remissioms and 2 patients still in accelerated phase. Five patients transformed to blastic phase. Conclusion: Imatinib induces heamatological and cytogenetic remission in majority of paticnts with chronic phase CML, but not in advanced phase (accelerated and blastic phase of CML phase) their response is likely to be much inferior to that in chronic phase. 137 PO-61 SOLITARY PLASMACYTOMA OF BONE-A CASE REPORT Anilmohanrao.S, Mahmoud El Hamidi, Khalid Abdulmoula Faculty of Medicine-Sorman Medical College-Seventh of April University,-Zawia. A 50-year-old male patient presented with pain in the back of Neck of 3-4 months duration. This is associated with quadriplegia. Radiological [X-ray] examination showed destruction of most of 3,4,5 cervical vertebral bodies. A clinical diagnosis of tuberculosis of cervical spine is made and biopsy is done from lesional site which is subjected to histopathology. ConclusionMicroscopic Examination showed tumour composed of sheets of proliferating plasma cells along with some binucleated cells,suggestive of solitary plasmacytoma of bone. 138 PO-62 PROPHYLAXIS OF VENOUS THROMBOEMBOLIC EVENTS IN MULTIPLE MYELOMA PATIENTS RECEIVING THALIDOMIDE Bouteraa W; Aissaoui L; Ben abdennbi Y; Kacem K; Ben Amor R; Jeddi R; Belakhal R; Ben Abid H; Belhaj Ali Z; Meddeb B Hematology department Aziza Othmana Hospital - Tunis - TUNISIA The incidence of venous thromboembolism (VTE) is more than 1% annually in the general population and increases further in cancer patients. The risk of VTE is higher in multiple myeloma (MM) patients who receive immunomodulatory drugs, especially in combination with steroid or chemotherapy. Various VTE prophylaxis strategies, such as low-molecular weight heparin (LMWH), warfarin or aspirin, have been investigated. We report our experience in the prophylaxis of VTE in myeloma patients treated with thalidomide. Thirty-three cases of MM diagnosed between June 2008 and January 2010 in the department of haematology in Aziza Othmana hospital and treated with regimens containing thalidomide (association thalidomide and dexamethasone for patients eligible for ASCT (group 1) or MPT protocol for elderly patients (group 2)). - In the first group, the thalidomide was given at 200mg/day for 75 days. 19 patients were assessed, the median age was 54 years (41 to 64 years) with a sex ratio at 0.9. To prevent VTE, Initially our patients received Acénocoumarol (Sintrom*) and the target INR was 2-3. 6 patients took this treatment. We don’t assess any VTE event but it was very difficult to manage this treatment especially for the patients who are leaving far from the hospital. For the 13 remaining patients, we choose to change to Aspirin (100mg/day). Only one event (7.6%) of VTE was diagnosed in a case of women patient with other comorbidities (diabetes, confinement). - For the second group, the thalidomide was given at 100mg/day for 18 months. 14 patients older than 65 years were assessed. The median age was 68.5 years old (63 to 85 years), the sex ratio was 1. All these patients had received Aspirin to prevent VTE. No VTE event was observed with a median follow up of 11.5 months. In the absence of clear data from randomized studies as a foundation for recommendations, the IMWG recommend that individual, myeloma-related risks of VTE and therapy-related risk factors should be taken into account in determining the type of thromboprophylaxis (a risk-assessment model). 139 PO-63 CD45 EXPRESSION BY BONE MARROW PLASMA CELLS AT DIAGNOSIS IN MULTIPLE MYELOMA: CORRELATION WITH MINIMAL RESIDUAL DISEASE Safra I, Lakhal A, Ladeb S, Ben jemaa R, Torjemane L, Abdeladhim B, Ben Othman T. Background: Multiple myeloma (MM) is characterized by accumulation of clonal plasma cells (PCs) in bone marrow. CD45, a key regulator of antigen-mediated signalling and activation in lymphocytes, is present in early stages of PCs development. CD45 is now established as a critical component of the signal transduction machinery of lymphocytes. Aims: In the present work we are interested in tracking the pattern of expression of CD 45 by malignant plasma cells at diagnosis in comparison with the degree of minimal residual disease after induction by Thalidomide and Dexamethasone. Methods: CD45 expression on multiple myeloma plasma cells and minimal residual disease quantification were studied by flow cytometry (FCM). A total of 14 patients (13 H, 1F) were studied at diagnosis and after first line therapy. Intensity of expression and the percentage of plasma cells are taken into account when determining the expression profile of CD45. Samples were considered CD45 positive, if they present more than 20% of plasma cells with bright CD45 expression (> 102). Response to treatment was evaluated by quantification of CD38 high CD138+ CD56+ cells. A lower threshold of 10-2 defined good response to treatment. Results: At diagnosis, the average of plasma cell bone marrow infiltration was 35% by cytology and 25% by FCM. There is a correlation between the percentage of plasma cells estimated by cytology and FCM with a significant value (p = 0.005). The expression of CD 45 was predominantly negative in 9 (64%) of 14 samples. Minimal residual disease separate two groups of patients: The first group: 6 patients with MRD > 10-2 and a profile CD 45 predominantly negative (only one sample was CD45 positive) and a second group: 8 patients with MRD < 10-2 with five samples were CD45 positive. Negative expression of CD45 is correlated with bad response to treatment (p = 0.05). Conclusion: In this study, we report a positive correlation between the expression of CD 45 and the therapeutic response. Further prospective studies are necessary to confirm this concept. 140 PO-64 MULTIPLE MYELOMA IN THE ELDERLY: TOLERANCE AND EFFICACY OF MPT PROTOCOL Bouteraa W; Aissaoui L; Ben abdennbi Y; Kacem K; Ben Amor R; Jeddi R; Belakhal R; Ben Abid H; Belhaj Ali Z; Meddeb B Haematology department Aziza Othmana Hospital - Tunis - TUNISIA Patients with multiple myeloma aged older than 65 years have traditionally received an oral regimen combining Melphalan and Prednisone (MP). The introduction of novel agents, such as immunomodulatory drugs and proteasome inhibitors, has substantially changed the treatment paradigm of this disease and reported an improvement in response rate and generally in survival. We report 14 cases of MM aged than 65 years diagnosed between June 2008 and January 2010 in the department of haematology in Aziza Othmana hospital and treated according to the MPT protocol. The median age was 68.5 years old (63 to 85 years), the sex ratio was 1. All patients were stage III A according to Durie and Salmon. Only one was B because of renal dysfunction. The majority of our patients (65%) had an IgG monoclonal component in the serum immunoelectrophoresis and 64% of cases had a kappa light chain. One patient presented a kappa light chain multiple myeloma. The assessment of the ISS was not possible for all the patients because of the lack of β2 microglobulin level in some cases. All the patients received MPT protocol (IFM 99-01) with Thalidomide dose at 100mg/day for 12 cycles. Only one patient (IgM Myeloma) received an escalated dose of 150mg/day after one cycle because of the hyperviscosity signs. The tolerance was excellent, Grade I peripheral neuropathy in two cases (14%), Grade I constipation in one patient (7%), Grade II neutropenia in one case (7%). All patients received Aspirin at 100mg/day as prophylaxis of venous thromboembolic events. We don’t assess any case of thrombotic events. Ten patients were assessable for response: complete remission (2 patients), Partial response (7 patients) and one patient had a response < 50%. All patients had a very good quality of life. Thalidomide in association with MP protocol is well tolerated and resulted a higher PR, VGPR, PFS and in some studies OS than MP alone. Actually data lend support to the use of MPT as the standard of care. 141 PO-65 ORAL MELPHALAN AND PREDNISONE CHEMOTHERAPY PLUS THALIDOMIDE IN ELDERLY PATIENTS WITH MULTIPLE MYELOMA M.Mdhaffar1, I.Ben amor1, S.Hdiji1, N.Ajmi1, H.Belaaj1, O. Kassar1, M.Elloumi1, K.Jammoussi2, Y.Hadj hmida3, F.Ayédi2, H.Masmoudi3 1:Service hématologie de Sfax, 2: Laboratoire de biochimie de Sfax, 3: Laboratoire d’immunologie de Sfax Introduction: Since1960, oral melphalan and prednisone has been the treatment of choice in multiple myeloma for patients older than 65 years. Recently the efficiency of the association melphalanprednisone and thalidomide (MP-T) has been proved in some studies. The objective of our study is to analyse the efficiency and tolerance of this association in patients treated in our department of haematology. Materials and methods: We included patients older than 65 years treated since 2006 for MM. Treatment consists of oral administration of melphalan at 5,5mg/m2 on days 1-4 or 4mg/m2 on days 1-7 and oral prednisone at a dose of 60mg/m2 on day 1-4 or 40mg/m2 on day 1-7. Each cycle was repeated every 4 weeks for six cycles. Thalidomide was administered at 100mg per day continuously during the six MPT cycles. The dose of thalidomide was reduced or stopped for sides effects. Anticoagulation prophylaxis was given by salicylic acid during Thalidomide treatment. The response to treatment was monitored by measurement of protein in serum or urine. We evaluated the hematologic and neurologic tolerance, and thrombotic complications. Results: Eleven patients were required aged 65 to 78 years having multiple myeloma (MM) de novo. The monoclonal myeloma protein was class Ig A in 6 cases, and class Ig G in 5 cases. 10 patients was stage III A and one patient was stage III B. After 6 cycles MP-T, 1 patient had near complete response, 6 patients had partial response and 4 had stable disease. Peripheral neuropathy (grade 2 to3) was reported in 5 patients, and thalidomide was reduce to 50% in 3 patients and stopped in 2 patients. One patient had developed a myocardial infarction despite the anti thrombosis prophylaxis with any deep veinous thrombosis. Constipation was noted in 2 cases and somnolence was noted in 1case. Two patients had developed haematologic toxicity to MP-T. Conclusion: According to the literature, the protocol MP-T became the reference treatment of the first line of multiple myeloma in patient older than 65 years, with a global response of 76% and global survival of 80%. In our study this protocol allowed to obtain a response of 63% of case with relatively acceptable toxicity. Such results lead us to continue this therapeutic. 142 PO-66 VAD AS INTRAVENOUS BOLUS AS FIRST-LINE TREATMENT IN UNTREATED MULTIPLE MYELOMA K.Kouidri; H.Zidani; R.Chafai; Y.Ouarhlent;M.Saïdi. Haematology, University Hospital, Batna, Algeria. Background: The classic VAD regimen is administered as a continuous infusion during four days induces rapid response without prejudicing stem cell mobilisation, but one of the disadvantages of this regimen is the need for a peripheral line that imposes in hospitalisation during the treatment. We examined and report the feasibility of VAD bolus as an outpatient schedule using 4 days of rapid infusion in patients with untreated multiple myeloma(MM) where high dose therapy is planned (young patients) or older with complications like: renal failure, hypercalcemia or neurological complications in which a rapid response is needed. Patients and methods: Seven diagnosed patients(pts) with symptomatic MM were included in a prospective study in our center. The VAD regimen consisted of vincristine 0,4mg and doxorubicin 9mg/m2 both in 100ml NaCl 0,9% by IV infusion(30mn) for 4 consecutive days.The dexamethasone was given by IVD at a dose of 40mg on days 1-4 and IM on days 9-12; 17-21 during uneven cycles. This regimen is administered every 28 days. Results: The 7 patients are 02 male and 05 female, the median age is 58,2 years(39-71 y); 05patients are less than 65years old. Staging was performed according to Durie and Salmon: stage IIIA:06, IIIB:01, all patients(100% stage III) had poor features. The response was evaluated according to the criteria of the ECOG one month after the last cycle of VAD bolus in 07 patients. An objective response was documented in 6pts (85,8%) whose achieved a partial response (PR) no patients achieved a complete response(CR) and one failure. The main toxicities was peripheral neuropathy in 02 patients (28,7%), infections reported in 01 patient (pulmonary infection). Conclusion: The VAD as rapid infusion is an effective induction regimen for multiple myeloma with 85% % response rate, acceptable toxicity and less cost. This regimen is interesting in our country because: the majority of poor prognosis, the majority of young patients before ASCT, the possibility of outpatient administration. 143 PO-67 SURGICAL SYNOVECTOMY OF THE KNEE IN YOUNG HEMOPHILIACS F.Benmegherbi, M.Bensadok, M.Belhani1, S.Fourmas, A.Benbouzid2, S.Khiar3 1 (Departement of hematology and blood transfusion: CHU Béni Messous) 2 (Orthopedics and Trauma Unit: CHU BenAknoun) 3 (Physiotherapy, CHU BenAknoun) Background: In Algeria; after a census of hemophiliacs in 2009, their number is of 1435 patients, of which 524 have less than 19 years and 250 whose age is not determined. Aim: The aim of this study is to assess the evolution of the results of synovectomy in the treatment of hemophilic arthropathies. Method: Between 2008 and 2010, 24 hemophilic patients of type A or type B were subjected to a total of 29 surgical procedures of which 14 orthopedic surgical procedures carried out in 11 children hemophiliacs. Eight synovectomies were performed in the Orthopedics and Trauma Unit in seven hemophilic children, of which 2 carried out on the same patient. The haemophilia was severe in all patients. Patients were between 7 and 16 years old at surgery. The viral contamination (HIV, HCV) was absent in all patients as well as the inhibitors. Indications of the synovectomy: too frequent hemarthroses, chronic hemarthrose, pain and deterioration of the function that was significant in all patients, the arthropathy is of stage III and IV of Arnold Hilgartner and the mobility of knee was of 102°. Substitution by antihemophilie factor was maintained during a couple of postoperative week, and then twice a week to ensure functional rehabilitation. The patients hemophiliacs has had consumed on average during their hospitalization 50000UI of factor VIII and 22500UI of factor IX, and between 48000UI and 96000UI for each factor, to cover functional rehabilitation. No hemorrhagic complications neither infectious, nor appearance of inhibitors after the surgery. The results after operations on moderate and severe chronic knee arthropathy were evaluated, with approximately 13 months follow-up period. 144 Results: This type of management yielded good and satisfactory results. In more than half of the knees, no episode of recurrent bleeding occurred. The effect of surgery on the range of motion was moderate with a usual loss of mobility of knee between 8,7° and 14°, recovered completely in some patients after rehabilitation. At one patient; the synovectomy was complicated of a stiffness of the member requiring 2 mobilizations under anesthesia. Conclusion: Elective surgery in moderate to severe chronic arthropathy produces good results when performed in a specialized centre and with multi-disciplinary approach; synovectomy gives good long-term results in term of bleeding recurrence and overall function. 145 PO-68 IRON STATUS OF VOLUNTARY BLOOD DONORS AT CHU TLEMCEN N.Merad-Boudia; F Zadjaoui; A.Ghaffour; S.Ayad; K.Dib Hematology biological hospital, Tlemcen, Algeria Do not harm donor is part of the blood donation ethical rules. However, it has been often found a significant reduction in iron stores at the donors of blood across many studies among this population. The aim of our study is to evaluate the status of iron among a population of no regular blood donors with a normal complete blood count at CHU Tlemcen. The total number of donors apparently healthy is 100 with an average age of 34 years, and a neat male predominancy (men: 73).The average rate of hemoglobin is 14.02 g/dl and the mean corpuscular volume is 87.75FL. The analysis of serum iron did not reveal hyposidérémie in most cases, but it has shown a depletion of iron stores at 38% in men (28 cases) versus 7. 4 % (2 cases) in women. The assessment of iron functional with soluble transferring receptors measurement has showed a decrease of iron functional in 28% of cases and a distribution relatively identical into the two sexes. Through the results of this preliminary study, would it undesirable to systematically fortify our blood donors? 146 PO-69 PAROXYSMAL NOCTURNAL HEMOGLOBINURIA: 3CASES REPORT F.Benmegherbi, M.Ramaoun, C.Kerrar, L.Louanchi, H.Ahmidatou, L.Bouriche, M.Belhani. Departement of hematology and blood transfusion: CHU Béni Messous Paroxysmal nocturnal hémoglobinuria described for the first time at the end of the XIXe century, is a disease of the hematopoietic stem cell, and the consequence of a somatic change of gene PIG - A Xp 22 which blocks the synthesis of GPI protein of anchoring of many proteins on the cellular surface: the DAF or CD55 and the MIRL or CD59 whose role is to inhibit the action of the complement. It is characterized by an important clinical polymorphism, it is a rare disease: 220 cases diagnosed in 40 years [SFH]. The diagnosis is ensured by the flow cytometry which allows the fast analysis of the various leucocytic and lymphocytic populations on peripheral blood. We report 3 cases of confirmed PNH followed in our consultation, 26 years old man and 30 years and 34 year old women, reveal by anemia, ictère with of dark urines in 2 patients, with a hemorrhagic syndrome in one patient, without thrombosis. Biology: pancytopenia in all patients with poor marrow in one patient, and rich with myelodysplasia (marrow and PBO) in the others, hémolysis was observed in all patients, and the diagnosis was confirmed by the flow cytometry. The treatment was symptomatic in all patients: blood and/or platelet transfusion. Danazol prescribe in all patients for 8 months average duration, with a good answer in 2 patients and stabilization in the other with a transfusional independence. The bone marrow transplant was indicated in one patient whose aplasia was severe, but without sibling donor. They are young patients, the anemia and hémolysis are constant, without thrombosis, the diagnosis of the PNH was confirmed by flow cytometry, Danazol is effective. Some drugs are potentially useful in this disease: the immunosuppresseurs employed successfully in very pancytopenic forms, the androgens seem to have an effectiveness, the allogenic BMT is the only curative therapeutic, but it is burdened with a heavy mortality in patients often multitraities, the targeted therapy: the éculizumab brought recently real hopes for the treatment of anemia. There are few patients by service of hematology, from where the interest to gather cases in Algeria, to develop the diagnosis means, and to propose a therapeutic strategy. 147 PO-70 HAEMATOLOGICAL MALIGNANCIES IN BENGHAZI IN THE YEAR 2009 Mohamed Lateiwish, Muftah Elsahati, Abdulhadi Haweel Hematology unit – Jamhoria hospital – Benghazi Introduction The Haematological Malignancies are a group of neoplasms that arise through malignant transformation of bone marrow derived cells. The great diversity seen in this group of disorders is a reflection of the complexity of normal haematopoiesis and the immune system. Aim of the study: The study was designed to present: 1) The demographic characters of the Libyan patients with hematological malignancies in Benghazi in the year 2009. 2) The incidence of the hematological malignancies among Libyan population in Benghazi in the year 2009. 3) The pattern of hematological malignancies in Benghazi in the year 2009. 4) The incidence of death among Libyan hematological malignancy patients in Benghazi in the year 2009. Material and Method A retrospective study was carried out in “hematology unit – Jamhoria hospital – Benghazi. The data was extracted from the files of hematological malignancy patients who were diagnosed in the year 2009. SPSS was used for data analysis. Statistics used; mean, standard deviation, median and percentages. Incidence rates and mortality rates among the patients were also calculated. Results: Seventy-one cases of malignant hematological diseases were registered in the year 2009 in the hematology unit at Jamhoria Hospital. Male to female ratio was 1.4: 1, the age of the patients ranged from 18 to 100 years, median age was 54 years, the overall incidence of hematological malignancy among Libyan population in Benghazi was 17.74 per 100000, the most frequent malignancy was non Hodgkin lymphoma (25.35% of all the cases) and its incidence was 4.5 per 100000. Acute lymphocytic leukemia, myelofibrosis, and Waldenstrom’s macroglobulinemia had the lowest frequencies (1.41% of all 148 the cases), their incidence was 0.25 per 100000. By the end of the year 2009, 8 out of the 71 cases were died with mortality rate of 11.27%. Conclusion: The distribution of the various hematological malignancies in this study is similar to the pattern reported in other studies. There appears to be generally a lower incidence of hematological malignancies recorded when compared to other studies. Late presentation, interference with the early start of treatment by the patients’ family as well as shortage of supportive treatment were the most common causes of death. 149 PO-71 ROSAI DORFMAN DISEASE: A CASE REPORT B Benzineb, A Arabi. S. Osmani,M Brahimi, B Enta Soltane, F Attaf, M Bey, H Tedj, N Yafour, H Berredouane, M A Bekadja. Department of haematology and bone marrow transplantation, University Hospital 1st November 1954-Oran-Algeria Rosai Dorfman disease is very rare histiocytosis syndrome (sinus histiocytosis with massive lymphadenopathy) ; the histological diagnosis is not easy. This is a case report of patient admitted in our service for pancytopenia on January 2009 He has no medical or familial antecedent. Clinical features are only pallor, asthenia, fever ; there were no adenopathy, no splenomegaly and no hepatomegaly. The bone marrow aspiration was poor ; a biopsy of bone marrow was made ; the diagnosis was tuberculosis and the patient received specific treatment during 40 days without any amelioration. A second bone marrow biopsy was made ; the diagnosis was metastatic process of renal cancer. Scanner of the abdomen show nothing in the renal site ; so, re-examination of the biopsy completed with immunophenotypic analysis showed a “Rosai Dorfman disease” In the literature, treatment of this pathology is not well established ; the patient received 1 cycle of COAP (cyclophosphamid – Oncovin – Adriamycine –Prednisone), with growth factor G-CSF, but the patient dies after 13 days of haemorrhage. 150 PO-72 CHARACTERISTICS OF PATIENTS WITH HEREDITARY SPHEROCYTOSIS IN ANNABA S.Bougherira – F.Grifi Department of Hematology, University Hospital of Annaba. Background. Hereditary spherocytosis is a very heterogeneous form of hemolytic anemia, the most common inherited RBC membrane defect. The aim is to provide the clinico-biological patterns RBC membrane disease in our department. Methods. Retrospective study collected 29 patients with HS diagnosed and treated between 1999-2009. The diagnosis was based upon the physical findings, blood cell examination, reticulocyte count, and osmotic fragility test. Results. Of 26 patients (11 men, 18 women), the mean age at diagnosis was 19 years (03 - 49 years), family history was positive in only 27% of cases, splenomegaly appeared in 88%,cholethiasis was present in 45%, haemolytic crises in 35% with 5% aplastic phases. The mean hemoglobin rate was 10 g/dl (5 - 15 g/dl), the mean reticulocyte count was 330 G/L, and the blood film shows spherical cells. The red cell osmotic fragility was increased in 85%. The transfusion was needed by 40%; splenectomy was performed in 40% and anemia being corrected in all cases. Conclusion. The definition of the red cell membrane defect in HS has no major clinical implications that are why it must be considered as a benign disease which is associated with a long survival. 151 PO-73 CLINICAL AND SCALABLE MYELODYSPLASTIC SYNDROMES A. Graine, S. Gherras, O. Ouanes, M. Allouda. N. Dali, H. Aftisse, K. Benallaoua, H. Ait-Ali Service Hematology Chu Tizi-Ouzou Algeria Introduction: The myelodysplastic syndromes (MDS) are clonal diseases, especially neoplastic affecting the elderly. They represent an heterogeneous group of acquired disorders of hematopoietic stem cells with dysmyélopoeise, giving rise to ineffective hematopoiesis and peripheral cytopenias. Development comes to bone marrow failure or AML. We report a retrospective study of 26 cases of MDS. Materials and Method: 26 cases of MDS were diagnosed in 1 period of 6 years (2003 to 2008). The average age is 66ans years, with extremes of 19 to 83 years, there is a female predominance (sex ratio 0.57). The diagnosis was made on the NSF, reticulocyte count, blood smear and medullogram, complemented by the color of pearls. The karyotype was not performed. The FAB classification was used. The treatment was mainly symptomatic transfusion of blood and platelets, erythropoeitine, androgens, B1 B6 Vitamin, iron chelator. Results: According to the FAB classification found in categories: Refractory anemia: 15 cases, refractory sideroblastic anemia: 3 cases, refractory anemia with excess blasts: 7 cases and CMML: 1 case. Overall survival was 50% at 5 years. Conclusion: MDS are evolving hematologic malignancies, to the worsening of cytopenias or LA. Better biological exploration (determination of erythropoeitine) and especially cytogenetics is essential to clarify the prognosis (according to IPSS) and best adapted treatement. 152 PO-74 PRISE EN CHARGE THERAPEUTIQUE DE LA FEMME ENCEINTE AVEC UN SYNDROME DREPANOCYTAIRE MAJEUR: A PROPOS DE 3 OBSERVATIONS, AVEC REVUE DE LA LITTERATURE SE Belakehal, S Baghdad, MC Rahali, D Saber-Cherif, H Mansour, FZ Ardjoun Service d’hématologie, HCA Introduction La grossesse au cours d’un syndrome drépanocytaire majeur est associée à une augmentation du risque de morbidité et de mortalité maternelle périnatale.

Pregnancy increases the incidence of sickle cell specific complications. The knowledge of these risks has contributed to the implementation of specific management program and to a better outcome of pregnancy. Such a program includes a close multidisciplinary approach for the duration of the pregnancy. The prophylactic blood transfusion or the transfusional exchanges in the event of a major sickle cell syndrome had been carried out per many authors. It is what we recommended in our small series. 156 PO-75 THROMBOPÉNIE NÉO NATALE ALLO IMMUNE Merine S, Houalef O, Abdi R ,Chalabi-Benabdallah A. Alors que l’allo-immunisation érythrocytaire est régulièrement rencontrée en Pédiatrie néonatale, l’allo-immunisation plaquettaire foeto maternelle est rare et peut être sévère en cas d’hémorragie intra crânienne.Elle résulte de l’immunisation maternelle contre les antigènes plaquettaires foetaux hérités du père et absents chez la mère. Dans la population caucasoïdel’antigène plaquettaire (Human Platelet Antigen) HPA-1a est le plus souvent impliqué. Les anticorps maternels IgG traversent le placenta et reconnaissent pour cibles les plaquettes foetales. Nous en rapportons un cas sévère, admis dans notre service.Observation: il s’agit d’un nouveau né admis à 24 h de vie pour un purpura thombopénique extensif apparu vers les heures précédentes et qui a nécessité 2unités plaquettaires en raison d’une thrombopénie à 5000. Dans les antécédents, on retrouve 2 avortements et une mort in utéro. Il existe une incompabilité foeto maternelle dans le système RH, mais les tests de Coombs direct et indirect sont négatifs. Les échographies prénatales avaient dépisté dés la 34é semaine une hydrocéphalie,qui a été confirmé après la naissance dans le service par le scanner cérébral, au niveau triventriculaire sans hémorragie intra crânienne. Le diagnostic de Thrombopénie néo natale allo immune, cliniquement évident peut être confirmé par un la mise en évidence d’une incompatibilité antigénique plaquettaire parentale avec présence d’un allo-anticorps maternel dirigé contre l’antigène paternel incriminé.Le risque de récidive très élevé (80%) doit faire envisager une prise en charge dans les grossesses ultérieures. 157 PO-76 HYDROXYUREA (HU) IN SICKLE CELL DISEASE (SCD): EXPERIENCE OF A SINGLE CENTER F. Lamraoui, C. Boucherit, M.T. Abad Department of Hematology, EHS CAC, Blida, Algeria Introduction Hydroxyurea is recommended in severe forms of sickle cell disease; HU significantly reduced the vaso-occlusive crises and mortality of the disease. Aims: To evaluate use of HU in patients (pts) with severe sickle cell syndromes in our country. Patients and methods From 2001 to 2009, 32 patients followed for SCD have been put under Hydroxyurea protocol, 21 S / S and 11 S / beta thalassemia, including 19 male and 13 female. Average age: 18.59 years ranging from 4 - 44 years. Average Hb S: 71.35%. Average Hb F: 22%. Average number of vasoocclusive crises (VOC) per year requiring hospitalization (28 pts): 5.62 (2-12). ACS: 1.4 (1-3). Number of blood transfusions (BT): 2 pts: no BT. 15 pts: under 15 BT. 14 pts: beyond 20 BT: 4 of which have received more than 40 BT. Splenic sequestration: 2 cases. Hypersplenism: 7 pts. Splenectomy: 10 pts. Hb: Average: 6.22 g / dl (5 to 8.5 g / dl). Criteria for inclusion in the protocol: severe VOC: 28 pts: 5.25 episodes / year (2 - 12), at least 1 episode of ACS was noted in 10 pts. Severe anemia: 5 pts. Priapism: 2 pts. Protocol: HU: Mean dose 14mg/Kg/j (12- 20mg/kg/j). Results Assessment of protocol HU: December 2009 Average VOC / year requiring hospitalization for 10 pts: 1, 6 (1-4). In 20 pts: total disappearance of the VOC; worsening of symptoms in 1 patient (no compliance to protocol), few episodes per year in 7 pts: 1.2 (1- 4). No SCA has been reported, no episode of priapism. Hb: 8g/dl (6 - 10g/dl), average gain of Hb = 2.1 g / dl in pts with severe anemia (Hb <7g/dl). Patients that receive punctually BT: 9 pts: 5 S / S, 4 S / beta thalassemia: 4 following a severe VOC, 3 following a severe anemia, 1 exchange BT for priapism, 1 patient S / beta thalassemia has a pulmonary and glandular sarcoidosis (parotid), he is still treated with steroids. Conclusion HU improves significantly outcome of SCD and quality of life in our country. 158 PO-77 IRON DEFICIENCY ANEMIA AMONG WOMEN M.T. Abad, N. Rekab, F. Lamraoui, S. Taoussi, S. Chebrek, S. Oukid,, C. Guezlane, C. Boucherit, K. Benlabiod, A. Bouchakor, H. Brahimi. Department of Haematology, EHS CAC Blida, Algeria. Introduction Iron deficiency anemia is the most common anemia in women in daily practice in hematology. Patients and Methods This retrospective case study examined 3865 cases of anemia observed over a period of 10 years (January 1999-December2008). It has identified 1746 cases of iron deficiency anemia in women. Results Median age was 31 years (16 - 94). The woman in genital activity represents the largest proportion of recruitment with 83.27%. Iron deficiency anemia was diagnosed during an ongoing pregnancy in 7.15%. The socio-economic conditions are bad in 25.3% of cases. The functional signs of anemia were the principal reason for visit (80%), rarely digestive disorders (0.63%) and bleeding (1.48%). In 16% of cases the discovery of anemia was made at a biological assessment for another reason. Clinically, anemic syndrome was associated with signs of iron deficiency in 50.6% of cases. Anemia was severe in 45.7% (Hb <7g/dL). The average MCV was 64.3 fl and MCHC averaged 27.6%. An iron status was performed only in 58% of cases; In most cases a therapeutic test with iron was made: he came back positive in 90% of cases: patients gained an average of 3, 4g/dl of hemoglobin in 3 weeks, the average basic rate of Hb was 7.3 and an average final rate 1O, 7 g / dl, an average gain corresponding to half of the deficit of hemoglobin. Mixed deficiency (iron and vitamin B9) was observed in 7.9% cases (average MCV = 86.8 fl) Severe anemia requiring blood transfusion was present in 46 cases (2.63%). The mechanisms of anemia were: • inadequate intake in 53.42% cases. • haemorrhagic syndrome in 32.58% of cases (haemorrhage: genitalia in 90.33% cases gastric in 7.73% cases, 1.94% in other cases • bad absorption in 4% of cases (celiac disease: 68.2%, gastric damage: 31.8%) • increased requirements in 10% of cases. 159 We further note after the etiological investigation cancer in 4 cases: 1 cervical cancer, 1 liver cancer, 1 sigmoid cancer, 1 bladder cancer. Comments Iron deficiency anemia is very common in haematology, it has 3 aspects: habitual and obvious presentation (presence of clinical and biological signs), already under treatment, latent often discovered accidentally. If the first presentation may be supported by any physician on the basis of a therapeutic test, the last two may require the determination of iron status and / or serum ferritin. Our study shows that the most common cause is the lack of supply due to poor socioeconomic conditions followed closely by the excessive losses. 160 PO-78 LAPAROSCOPIC SPLENECTOMY IN SEVERE IMMUNE THROMBOCYTOPENIC PURPURA (ITP) C. Guezlane 1, R. Benhizia 2, S. Oukid 1, S. Taoussi 1, S. Chebrek Lamraoui 1, E.M. Si Ahmed2, M.T. Abad 1 1, F. 1: Department of Haematology, EHS CAC Blida, Algeria 2: Department of Surgery, University Hospital Blida, Algeria Classic splenectomy was the only abdominal surgical approach for removing the spleen until the advent of laparoscopic splenectomy. Aims: To assess the results of laparoscopic splenectomy performed in our patients since three years, we present a preliminary study of 20 patients splenectomized by this method. Materials and methods) From January 2006 to December 2007 18 patients were splenectomized by laparoscopy,14 adults and 4 children, male in 06 cases and female in 12 cases. The mean age at diagnosis was 25 years (07-58 years). In biological terms, severe thrombocytopenia (platelets <20 000 / mm 3) was found in 66% of these patients. The first therapeutic weapon was corticosteroids in all cases. In the evaluation of corticosteroid therapy, 06 patients were corticodependance, 07 patients in total failure, 05 were submitted after remission of 1 to 7 months of recurrent thrombocytopenia. Preparation for splenectomy included systematically bolus of steroids the day before surgery, and a hospitalization for one day. Results) Splenectomy was performed within 03 to 48 months after diagnosis (mean: 15 months). During abdominal exploration, accessory spleens were systematically explored. After splenectomy, complete remission (CR) was achieved immediately in 14 (77%) patients, failure in 2 (8.6%) patients. A failure is a patient died of diabetes known before ITP. After splenectomy, the surgical stay does not exceed 03 days. The postoperative course was simple: no incident of infection or bleeding was noted. An early thrombocytosis was noted in 16 patients without thrombosis proved. The study of pathological part of splenectomy has solved a case of non-Hodgkin’s splenic lymphoma. In the long term evaluation (24 to 36 months), 11 patients (61%) were considered cured, 03 patients (17%) initially in CR relapsed after one to 06 months and released under steroids RC. 161 The median survival was 39 months (33-48 months). Overall, laparoscopic splenectomy is a procedure therapeutic alternative to splenectomy bloody. The latter benefits are numerous: reduced anesthesic risk, shortened hospitalization, reduced infectious complications. 162 PO-79 PROGRAM OF EXCHANGE TRANSFUSIONNEL TO THE DREPANOCYTIC: EXPERIENCE OF HAEMATOLOGY DEPARTMENT CHU ANNABA H Belaidi - H. Hamdane - L. Oulad diaf- F. Grifi. Haematology department of Annaba, Algeria Introduction: The Transfusional Exchange (TE) is one of the means of fight against the complications of the sickle cell disease, uses in fall of certain severe complications or in prevention in situations has risks, with the aim of reducing the concentration of the haemoglobin S. Patients and methods: Retrospective, descriptive study, spreading out over 2 years (January 2008 - December 2009), including the drepanocytic patients to whom we realized TE for diverse indications. The preliminary biological examinations were: erythrocytaire phenotype, FBC and blood film, electrophoresis of the haemoglobin, the serology HCV, HBs, HIV, and in a fickle way: ferritine, renal and hepatic balance assessment, echocardiography. For all the patients we have used phenotyping red blood cells transfusion. Results: 25 patients collected 7 men and 18 women, the average age of which is of 31 years (17 - 45 years). The majority of these patients are homozygous drepanocytic (14 patients). The pregnancies and the cholecystectomys were the most frequent indications. 2 patients had a positive preliminary serology the one for the HCV, the other one for the HBs. The average number of sessions of TE by patient was 2.8 (1 - 6). A good profile of tolerancy was note at all the patients. The rate of Hb S achieves later TE: 40 % (14 patients), 30 % (5 patients), and > 40 % for 6 patients. All the deliveries took place normally except one case of death. The surgical operations are realized without complication. One patient died, 20 days after her first session of TE in acute chest syndrome. Conclusion: Transfusional Exchange is a major therapeutic weapon in the care and the prevention of the numerous complications. 163 PO-80 THE BLOOD TRANSFUSION PROGRAM FOR Β THALASSEMIA PATIENTS: METHODS AND RESULTS F. Grifi – H. Belaidi – N. Meliani – A. Djenouni. Haematology department of Annaba, Algeria Introduction: The blood transfusion program of CG in the purpose of maintaining a haemoglobin rate compatible with the lifespan, is the basis to take charge of β-Thalassemias major patients. But these frequent blood transfusions generate complications which need prevention and case management. Patients and methods: A case-control study on a cohort of 40 β-Thalassemia main patients, taken in at the haematology department during 2009. The diagnosis was applied at the paediatric department, where a blood transfusion program has started and continued till the age of 06. At our level, the blood transfusion program is followed by phenotypes CG. Results: Only 25% of patients receive blood. The blood transfusion rate is different according to the requirements of patients: every 21 days for 8 patients, all months for 5, every two months for 12, every three months for a transfusion after more than three months for 9.3 of our patients have received no blood transfusion during 2009. 62.5% of the patients are given hydroxyurea, 85% were under splenectomy. Iron chelation is made through desferal in bolus for most patients (34 patients), only 6 patients use the subcutaneous way by a pump. 17 patients have a ferritinemy rate <2000 ng/ml, 2 patients have more than 10000 ng/ml. The degenerative visceral complications are dominated by the cardiopathies (9 patients). 8 patients were given a seroconversion towards HEPATITIS C VIRUS. Most of our patients have a failure to thrive. Conclusion: The blood transfusion program remains a major element in taking in charge β-thalassemias patients which do not respond to the hydroxyurea, but which advantage is limited by many inconveniences: iron excess, viral transmission, which are difficult for the patients. 164 PO-81 SEROPREVALENCE OF HEPATITIS C AMONG PATIENTS WITH HEMOGLOBINOPATHIES A.djenouni1-f.grifi1-amoura2-dekhil2 1 - Hematology Department CHU Annaba 2 - Laboratory of Bacteriology CHU Annaba 3 - Faculty of Medicine Badji Mokhtar Annaba, ALGERIA Introduction: The prevalence of hepatitis C in the haemoglobinopathies is important in relation to transfusion therapy. Hepatitis C leads to a greater liver mortality in these patients favored by iron overload. Objective: This work aims to determine the seroprevalence of hepatitis C among patients with hemoglobinopathies, followed at our department. Patients and Method: This cross-sectional study, 263 patients followed with interest for a hemoglobinopathy:- 205 major sickle cell syndromes- 42 β thalassemia major - 16 cases of hemoglobinopathies. The study extends from the recruitment of patients until December 2009.Viral serology (ELISA for 3rd generation) is done systematically and regularly with varying frequency depending on the type of haemoglobinopathy and transfusion rate, if this test is positive a second time and again by a complete liver function and a PCR order assess the viral load and have the genotype. Results: Of 263 patients, 41 had a positive HCV serology, an overall prevalence of 15.5%, a rate higher than that found in the general population. The average age of these patients was 28 years with a range of [15-58 years], sex-ratio is 2.4. The sero-prevalence in each type of hemoglobinopathy is as follows:- Sickle cell syndromes-major: 15%, 65% are homozygous forms- β thalassemia major: 19% - Hemoglobin C: 6%. 60% of cases with positive HCV antibodies have a history of transfusion, of which 54% are multitransfused. In 54% of patients, hepatitis C has evolved to chronicity and 5% liver cirrhosis. Conclusion: The life expectancy of patients with congenital hemolytic anemia has considerably improved, particularly in patients with thalassemia and sickle cell disease. But it remains a significant morbidity and mortality secondary to viral infections. 165 PO-82 SEVERE CONGENITAL NEUTROPENIA: CASE STUDY C.Aboura, N.Zidani, M.Bensadok, L Oukrif, A.Bensenouci, M.Belhani Service Hematologie CHU BeniMessous Service Pediatrie CHU BeniMessous Introduction: The severe congenital neutropenia (SCN) a heterogeneous group of hematologic disorders,pose a molecular diagnosis problem,the vital prognosis would be fatal shortly by recurrent severe bacterial infections very early in the neonatal period. Defining characteristic of all these diseases is the presence of severe neutropenia with absolute neutrophil counts less than 0.5X109/L Bone marrow objective a maturation arrest of myelopoiesis at the promyelocyte stage of development. The introduction of recombinant human granulocyte-colony stimulating factor (rHuG-CSF can maintain ANC above 1.0 × 109/l. and thus substantially reduce the risk of infection. The hematopoietic stem cell transplantation (HSCT) is still the only currently available treatment. The Prognosis depends on the response to growth factors,and the evolution to leukemia. Case report: An infant of 9 months Personal history: Born at term of pregnancy without problems,he has received the vaccination of first month. Family history: Born from a nonconsanguineous marriage. 5th in a family of 05 children,no similar cases in the family. History of disease: From the fifth day of life the infant presented repeated infections: omphalitis, furunculosis and urinary tract infection. At 45th day he presented minor salmonella septicemia. At 90th day he presented a consequent otitis of mastoiditis which was treated surgically, but a complicated specis wall with sepsis was treated by ablation of the pinna. Transfused twice for severe anemia with a hemoglobin level 3g/dl rate,WBC: 6000 but ANC not done. Determination of immunoglobulin + test nitroblue tetrazolium reduction = normal. At admission, the child had a deterioration of general state- fever and an intense cutaneous mucus paleness with stomatitis. He had an abscess of anal margin and foot. Peripheral facial paralysis, without tumor or hemorrhagic syndrome. 166 Hematological exploration: Complete blood count WBC= 4400 and severe neutropenia,absolute neutrophil counts (ANC) =352/mm3 + hypochromic anemia with hemoglobin 5.4g/dl, Bone marrow:became rich, megakaryocytes are present but abnormal, granular 24% with maturation arrest of the granular promyelocytes, erythroblasts 44% = 3% lymphocytes, with signs of myelodysplasia. Molecular biology: not done. Karyotype: not done Treatment and follow-up: Treatment of the bacterial infections and treated with recombinant human granulocyte-colony stimulating factor (rHuG-CSF daily as subcutaneous injection with individual doses ranging between 0.27 and 120 mcg/kg/day at 20th day of treatment WBC: 480/ mm3. Despite no significant response, reduction of development frequency and severity of infections is noted. Comments: The severity of the clinical pattern is based on: -Repeated bacterial infections. - Permanent neutropenia with presence of monocytes and absence of lymphopenia. -Maturation arrest at the stage of granular promyelocytes. -Hypergammaglobulinemia The diagnosis is probably: severe congenital neutropenia with ELA2 mutation. Our patient belongs to the group of patients at particularly high risk of leukemia: -Signs of myelodysplasia in medullogram. - Lower neutrophil responds poorly under high doses of G-CSF. The only treatment is hematopoietic stem cell transplantation (HSCT) Conclusion Early diagnosis prevents children from irreversible complications (removal of the external ear in our patient 167 PO-83 SPECIFICITIES OF UNEXPECTED ANTIBODIES TO RED BLOOD CELLS: ABOUT 154 CASES H. Khemakhem, S. Boukhriss, L Ifa, H Guedria, S. Hadhri, H Skouri Laboratoire Hématologie et Banque du Sang – CHU Sahloul Sousse – TUNISIE Background and objective: The blood transfusion exposes to two major complications: immunological accidents and transmission of infectious agents. The rules to prevent such complications have been already specified by Tunisian laws, especially the circular 49/05. The search for unexpected antibodies to red blood cells (UAR) is indicated mainly in pregnant women, patient to be transfused and polytransfused patients. Through our experience at the blood bank of the Universitary Hospital Sahloul in Sousse, we report indications and methods of practice for UAR as well as specificities of the found antibodies. Patients and methods: From the lab’s register for UAR, initiated since August 1995, we analyzed various specificities of the found antibodies. The search for unexpected antibodies was carried out following transfusion reactions, incompatible crossmatch and systematically for polytransfused patients. The search for UAR included screening and identification by means of Coombs LISS and enzymatic methods using microgel Diamed technique. Results: Over a 15 years period, 4656 search for UAR were carried out, of which 154 (3.3%) were positive. The immunization against Rhesus system was the most prevalent (63 cases): (anti-D:34 cases, anti-E:14 cases, anti-C:8 cases, anti-e:4 cases and anti-C:3 cases). In 91 cases, they found specificity is different from Rhesus system, including 27 non interpretable cases. The high rate of anti-red cells immunization found in our study could be explained by the load of transfusions received and/or the multiparity. Conclusion: Collaboration between laboratory and clinical departments is necessary to promise blood transfusion safety. 168 PO-84 VIROLOGICAL FOLLOW-UP OF PATIENTS WITH CONGENITAL BLEEDING DISORDERS OTHER THAN HAEMOPHILIA. STUDY ABOUT 33 PATIENTS N. Louati*, A. Dhieb*, J. Cherif *, I. Ben Amor*, H. Bellaaj**, H. Rekik, M. Elloumi**,J. Gargouri * * RCBT-Sfax, ** Department of clinical hematology-Sfax-Tunisia. Introduction Assuring transfusion viral safety is a medical and public preoccupation. The surveillance of multitransfused patients is one of its facets. In this frame, we notify the seroconversion rates of the viral markers of hepatitis B (HBV) and C (HCV) viruses and human immune deficiency virus (HIV) in patients with congenital bleeding diseases other than hemophilia who are repeatedly transfused with cryoprecipitate or fresh frozen plasma. Patients and methods Our prospective study was conducted between 1994 and 2009 and concerned 33 patients: 13 with von Willebrand disease, 15 with factor XIII deficiency, 4 with factor VII deficiency and 1 with factor XI deficiency. The screening of the viral markers of HBV, HCV and HIV was performed every 6 months using the last generation of immunoenzymatic techniques of instant: hepatitis B surface antigen, HIV antibody then antigen P24 and HIV antibody and HCV antibody then HCV antigen and antibody (successively 2nd, 3rd, and 4th generations). The confirmation of HCV or HIV positive serology was carried out using Immuno-Blot. Biological screening of blood donations was instituted, in Tunisia, in 1971 for HBV, in 1987 for HIV and in 1994 for HCV. Results The total number of labile blood plasmatic products transfused was 6567 (199 / patient, extremes: 3-1422) including 5016 cryoprecipitate for von Willebrand disease (385,84 / patient, extremes: 30-1422) and 1551 fresh frozen plasma for other disorders (77,55 / patient, extremes: 3-499). In inclusion, 4 patients (2 men, 2 women), transfused before 1994, had a positive HCV serology. During the follow-up, we noted one case of seroconversion for HCV (3 %) (in 1996) at von Willebrand’ patient transfused since 1993. There was no case of seroconversion for HIV or HBV. Conclusion The residual risk of transfusion transmitted viral diseases, even very low, persists due to the serological window. The sensitization of doctors of blood collect and the blood donors themselves is more beneficial for transfusion safety particularly by auto-exclusion and improvement of regular donations. The development of autologous blood transfusion and the implementation of viral inactivation methods would more enhanced transfusion safety. 169 PO-85 TRANSFUSION VIRUSES MARKERS AMONG HAEMOPHILIACS ; A STUDY ABOUT 58 CASES T. Rekik.*, N. Hentati.*, M. Rekik.*, I. Ben Amor.*, N. Ajmi**, H. Rekik.*, M Elloumi.** et J. Gargouri.* * RCBT - Sfax, ** department of clinical hématology - H. Chaker university hospital - Sfax, Tunisia Introduction Hemovigilance is a system of surveillance and alert which contributes to improved the transfusion safety. Preventing transmission of infectious diseases is a principal safety concern. A regular follow-up of the viral markers of hepatitis B (HBV) and C (HCV) viruses and human immune deficiency virus (HIV) in multitransfused hemophiliacs was introduced in our blood transfusion centre since 1993. We report seroconversion rates among these patients transfused with local plasma derived products and clotting factor concentrates imported from Western Europe. Patients and methods Our prospective study (1993-2009) included 58 hemophiliacs aged between 1 and 64 years: 50 hemophiliacs A transfused with cryoprecipitate and factor VIII concentrates and 8 hemophiliacs B transfused with fresh frozen plasma and factor IX concentrates. The detection of HBs antigen, HIV antibodies then HIV antigen and antibodies (2008) and HCV antibodies then HCV antigen and antibodies (2007) was carried out every 6 months by immunoenzymatic technique. The confirmation of seroconversion for HCV and HIV was made by Immuno-Blot. It should be noted that, in Tunisia, screening of blood donations was implemented in 1971, 1987 and 1994, respectively, for HBV, HIV and HCV. 170 PO-86 IMMUNOSUPPRESSIVE THERAPY IN SEVERE APLASTIC ANEMIA: A SINGLE CENTER EXPERIENCE ABOUT 13 CASES Saidi I, Ben amor R, Jeddi R, Aissaoui L, Kacem K, Bouteraa W, Abdennebi Y, Ben abid H, Bel hadj Z, Ben lakhal R, Meddeb B. Aziza Othmana Hospital, Tunis Background: Immunosuppressive therapy (IST) with antithymocyte globulin (ATG) plus cyclosporine (CSA) is standard therapy in patients with severe aplastic anemia (SAA) who do not have an available HLA-matched sibling donor. We retrospectively analyzed the data of patients with SAA, to evaluate results and feasibility of the IST in our center. Patients and methods: Between February 08 and December 09: 13 patients, with confirmed SAA and no related donor, were treated in the Hematologic Unit of Aziza Othmana Hospital. Seven patients (53%) were from north Tunisia (5 north west), 4 from south and 2 from center of Tunisia. The initial symptoms were hemorrhage in 12 patients, associated to anemia or fever in 8 patients. Isolated anemia was noted in one patient. All patients received IST with either rabbit ATG (n = 9) or horse ATG (n = 4) plus cyclosporine (CSA) and supportive care until recovery of hematopoietic function. No G-CSF used. Results: The median age was 19 years (7- 57). Sex ratio: 3,3 (10M/3F). At diagnosis: all patients had a platelet count lower than 20.000/mm3, 7 patients had a neutrophil count rather than 200/mm3 (very SAA) and a median of Hemoglobin level at 6,7 g/dl. HPN clone was positive in 4 cases. The median delay between first symptoms and diagnostic was 5 weeks and between diagnosis and treatment 10 weeks. Three refractory patients died from bleeding respectively at 1 month, 5 months and 6 months. At 6 months; 6 patients did achieve a complete (n=5) or a partial response (n=1). A second course of treatment was performed in only 50% of refractory cases (2/4) and permitted the achievement of partial response, 5 months later, in one case. Actually, with a median follow up of 15 months (3-26): 8 patients (62 %) had a significant response: 5 patients (40%) are still in complete response and 3 patients (22%) are in partial response without supportive transfusion needed. Conclusion: In our study 85% of patients with neutrophils count ≥ 200/mm3 (6/7) and 75% of patients with HPN clone (3/4) at diagnosis; did achieve good responses. These two criteria are largely de- 171 scribed in literature, but we need a larger number of patient’s panel, to have a significant statistics study. We note also that delays between first symptoms, diagnostic and treatment are extended (15 weeks), which may contribute to failure of response. Finally, our, first experience results, are encouraging and may be compared to those described in the different publications. 172 PO-87 RED CELL EXCHANGES IN SICKLE CELL DISEASE. A STUDY ABOUT 20 CASES S. Chortani*, I. Rekik*, I. Ben Amor*, T. Rekik, O. kassar**, F. Ben Said***, H. Rekik*, M. Elloumi**, J. Gargouri* * RCBT - Sfax, ** department of clinical hématology - H. Chaker university hospital - Sfax, *** regional hospital of Gabes - Tunisia Introduction Red cell exchange is important in the management and the prevention of complications of sickle cell disease. They permit to avoid hyperviscosity and martial overload. Our aim was to evaluate the benefits of red cell exchanges in the care of sickle cell patients. Patients and methods Twenty patients were enrolled in our prospective study (1996- 2009): 15 homozygous sicklecell disease S/S, 1 heterozygous sickle-cell disease S/A, 2 sickle cell-beta-thalassemia, 2 sickle cell-hemoglobin C disease. Red cell exchange was carried out, at the beginning, using a manual technique (10 procedures) then, since 2004, using a continuous flow blood cell separator (Cobe Spectra) (63 procedures). Replacement was done with phenotyped (Rhesus- kell) and deleucocytated (since 2000) red cell concentrates. Biological controls were done before and after each procedure (hemogram, ionogram, PT, ACT, calcemy and haemoglobin electrophoresis). Results The mean age of patients was 22,52 years (extremes: 11-48) and the sex-ratio was 4. A total of 73 procedures of red cell exchanges have been performed (mean: 3,61, extremes: 1- 25), including 47 procedures done within a prophylactic transfusion program(every 2 months) in 3 patients with a history of sickling complications. Red cell exchange was indicated in several circumstances: severe painful crises, stroke, acute chest syndrome, priapism, osteonecrosis, or in preoperative. The mean duration of the red cell exchanges was of 96,52 min (extremes: 60-178 min) with a mean exchanged volume of 2021 ml (extremes: 1118-2879 ml) and a mean decrease of 61,59% (extremes: 35,46-77,85 %) in the circulating sickle haemoglobin (HbS) level. The haematocrit was growed from 28.89% before exchange (extremes: 15,3-36%) to 31,22% after exchange (extremes: 25-39%). The clinical evolution was favorable with a clear improvement of symptomatology. Red cell exchange was well tolerated by most patients. Adverse effects were limited to shivers hyperthermia (2 cases), painful crisis having yielded under antalgic and morphinic treatment (2 cases). A premature stop of the procedure was noted in 1 case (problem of veins). 173 Conclusion Though constraining and expensive, red cell exchange is an effective treatment of sickle cell anemia. It enables a rapid decrease of percentage of circulating HbS levels either prophylactically or therapeutically. Moreover, they make possible a comfort notable life to the patients. Automated methods using cell separators allow this procedure to be performed rapidly, effectively and safely. 174 PO-88 MASSIVE TRANSFUSION: RISK FACTORS AND CLINICAL OUTCOME H. Hmida; S. Boukhris; L. Ifa; H. Khemakhem; H. Regaieg; S. Hadhri; H.Guedria; H. Skouri Laboratoire Hématologie et Banque du Sang – CHU Sahloul – Sousse -TUNISIE Background and objective: Emergency and massive transfusion (MT) represents a particular challenge for clinician and transfusion medicine specialist. We retrospectively assessed the incidence of MT at our institution during a 10 years period. Patients and methods: Local blood bank records were searched for MT episodes occurred from January 1999 to December 2009. MT was defined as the transfusion of 10 or more packed red cell (PRC) units within 24h. Clinical data were collected from medical records of patients. Results: One hundred and four patients had a massive transfusion. (125 men and 49 women; mean age 55 years (13-81)). They received 13.14 PRC units (10-33), 17 fresh frozen plasma (FFP), and 10 packs of standard platelets (0-33); in the context of cardiovascular surgery (n=112), polytrauma (n=36), upper digestive bleeding (n=10), others (n=16). Patients were hospitalized in intensive care unit (n=57), department of cardiovascular surgery (n=112), others (n=5). Mortality rate was 51%. Multivariate analysis identified renal failure (OR=4.32 ; 95% confidence interval [CI], 1.4-3.1), acidosis (OR=4.8 ; 95% CI, 2.5-9.5), acute pulmonary edema (OR=9.5 ; 95% CI, 2.1-43) as significant independent predictors of mortality. Conclusion: Overall, the mortality rate among patients receiving MT was very high, and was influenced by renal failure, acidosis and acute pulmonary edema. 175 PO-89 SEROPREVALENCE VIRAL MARKERS IN HEMOGLOBIN DISORDERS. STUDY ABOUT 101 PATIENTS A. Dhieb, I. Rekik, T. Rekik, J. Cherif, N. Louati, I. Ben Amor, H. Rekik, J. Gargouri RCBT-Sfax -Tunisia. Introduction The infectious safety of blood transfusion has steadily improved in recent years. The goal is to achieve “zero” risk. In Tunisia, the transfusion safety is assured by medical selection of blood donors and a screening of markers of hepatitis B virus (HBV) since 1971, human immune deficiency virus (HIV) since 1987 and hepatitis C virus (HCV) since 1994. However, it still remains a very low residual risk related to virological window period. The purpose of our study was to report seroconversion rates of HBV, HCV and HIV among multitransfused patients suffering from hemoglobinopathies. Material and methods: It is a prospective study (1994 - 2010) conducted on 101 patients with hemoglobin disorders: 68 sickle-cell disease, 28 beta-thalassemia and 5 sickle cell-beta-thalassemia. These patients have required repeated transfusions of labile blood products (LBP) or red cell exchanges. detection of viral markers has been made to the demand of the first LBP then every 6 months using the last generation of immunoenzymatic techniques of instant (hepatitis B surface antigen, HIV antibody then antigen P24 and HIV antibody and HCV antibody then HCV antigen and antibody (successively 2nd, 3rd, and 4th generations). The confirmation of HCV or HIV positive serology has been achieved by Immuno-Blot. Result: The mean age of patients was 13,16 years (extremes: 1 - 45 years) at the time of their inclusion. The sex-ratio was 1,4 (59 men, 42 women). These patients received a total of 3 721 LBP with an average of 45,93 LBP per patient (extremes: 1-291). In inclusion, one patient had hepatitis B positive serology. During the follow-up, we have noted 1 HBV seroconversion (0,9%) in 2009 after transfusion of 97 red cell concentrates, 1 HCV seroconversion (0,9%) in 2004 after transfusion of 17 CGR and no case of HIV seroconversion. Conclusion: Monitoring multitransfused patients enters a general framework of hemovigilance. Its aim is to evaluate the blood viral safety and to make the necessary corrective actions. Moreover, carrying out viral transmission enquiries would lead to better transfusion risk estimation. 176 PO-90 RED BLOOD CELLS TRANSFUSION IN A TUNISIAN HAEMATOLOGY DEPARTMENT: ASSETS AND PROSPECTS Hentati N, Ben Salah N, Jaouadi L, Belakhal F, El Borgi W, Gouider E, Hafsia R Laboratoire d’Hématologie Biologique de L’Hôpital Aziza Othmana Blood transfusion is an integral part of the daily activities in the department of haematology of Aziza Othmana hospital. It is a high risk activity which is governed by legislative and lawful texts. This is a descriptive study which is carried out from January 1, 2007 to December 31, 2009. During this period, 12194 RBC transfusions were done. The blood grouping is done into micro plate. A chart of blood group is delivered to the patient after having validated his group and phenotype by two determinations carried out of two distinct lacings. All the patients are transfused by RBC concentrates phenotyped in the Rhesus and Kell systems. Deleucocytation of RBC concentrates is done when required. The research for irregular antibodies (RAI) is not compulsory in Tunisia; it is done before the first transfusion and in the follow-up. On the whole, 2358 search for irregular antibodies were carried out of which 83 were positive due to allo antibodies. Conformely to the law, the direct test of compatibility was done in all cases by indirect antiglobuline test. We noted an incompatibility in 144 cases (1, 18%) which correspond to 56 patients (18 auto antibodies, 19 allo antibodies, 15 positive direct coombs test of the RBC concentrates, 4 antiprivate antibodies). Compatible RBC concentrates were found and delivered in all these cases. The ultimate test at the bed of the patient, obligatory in Tunisia, is regularly done before each transfusion. The blood bank did create a computer file in order to follow up transfused patients. The transfusion register is updated, but there are insufficiencies concerning the cards of transfusion which are missing in the medical record of almost all patients. Declaration of transfused incidents did start only since January 2009. Only 13 incidents were noted (allergic reaction, thrill hyperthermia reactions). We did not note any severe haemolytic incident. In the aim to reduce the time of satisfaction of the demands, a transfusion program was developed for the regular transfused patients. Nevertheless, delays of satisfaction of the demands still have to be improved. Among efforts to respect the law and to improve quality of life of our patients, many measures should be taken, essentially in hemovigilance and in delays of distribution of blood. 177 PO-91 GAUCHER DISEASE: HEMATOLOGICAL ASPECTS AND DIAGNOSIS H. Ahmidatou, M. Ramaoun, M. Bensadok, L. Bouriche, C. Kerrar, L. Louanchi, M. Belhani Hematology department beni-Messous hospital Algeries Algeria Introduction Gaucher disease is the most frequent storage disease and corresponds to an inherited deficiency of glucocerebrosidase. Due to excessive accumulation of glucocerebroside in macrophage present especially in bone marrow, cytopenia and splenomegaly occur. Objectives Gaucher disease remains a rare pathology, the aim of our study is to: - show the process of diagnosis in front of hematological manifestations - classify the patients into 3 types - Discuss the enzymotherapy replacement indication. Methods We reported 4 cases of patients with Gaucher disease, 3 were women and 1 was a man, mean age at diagnosis was 30 years. Results The main features were: splenomegaly (1), bleeding (ecchymosis, epistaxis) (5), pallor (3). Laboratory tests showed: anemia (3), thrombocytopenia (2), bicytopenia (2) and hyperferritinemia (1). The diagnosis was evoked by the bone marrow aspiration cytology and obtained by the identification of Gaucher’s cells on bone marrow biopsy examination for our 4 patients, confirmed by the enzymatic activity dosage only for 2 patients. Our patients present Gaucher disease type 1, form without neurological manifestations. Substitutive enzymoyherapy was not performed for our patients; they had just needed a regular follow-up. Discussion The diagnosis of Gaucher disease was made in adult age in our study, forms discovered at this age are frequent. This result is similar to those found in previous studies. Splenomegaly was found only in one patient, when, it’s present in 90% of patients in other series. The diagnosis 178 was easy for 3 patients; bone marrow aspiration was done at the first examination but, for the 4th patient, the diagnosis was made after exclusion of all the other causes of hyperferritinemia. Enzyme replacement therapy is now available, it’s indicated when the hematological manifestations are severe, our patients have mild symptoms, and they haven’t needed any treatment at all. Conclusion Gaucher disease often appears in childhood, some patients are diagnosed in adulthood. It’s important to evoke this disease in front of unknown etiology hematological manifestations. It’s the bone marrow aspiration cytology which allows the diagnosis 179 PO-92 INVESTIGATIONS ABOUT TRANSFUSION INCIDENTS: 13 CASES REPORTED S.Chichoune; F.Soltani; F.Kacha; A.Ounissi; H.Hamza; H.Zidani; K.Kouidri; M.Saidi. Haematology, University Hospital, Batna, Algeria. Blood transfusion consists of 03 major adverse effects that can make patient’s life in danger, are: immunologic risk, infectious risk and the risk of over loading. At the present time the grave immunologic accidents are exceptional, the immunologic incidents remain particularly frequent in our patients. Patients and methods: It’s about a retrospective study, analysing a number of incidents met in the haematology unit during the last year. Results: Among 1312 LBP transfusions effected, 13 incidents of immunologic and allergic type were met 1%: - shudder fever syndrome: 4, - allergic reactions: 08, - TRALLI syndrome: 01. These complications were met among polytransfused patients: - aplastic anemia: 05 patients - acute leukemia: 04, - thalassemia: 02, - myelodysplasia: 01. The nature of LBP(labile Blood Product) offending is divided into: 07 incidents were in relation with transfusion of platelets: 06 of SP(Standard Platelets) and 06 after red blood cells(RB). The TRALLI syndrome occurred during RB transfusion in a young poly transfused patient, manifesting with dyspnea,hypotension, crackles, and hypoxia, resolved after the stopping of transfusion and oxygen therapy. Conclusion: The frequency of immunologic and allergic incidents is not rare: 01% occurred in particular patients: poly transfused and immunodeficiency. The platelet transfusion is the most frequent in these incidents specially the standard platelets which provide in multiple donors. Single donor aphaeresis must be necessary provided. However, the practise of immunologic tests(research of HLA antibodies among the giver and recipient) is not performed. 180 PO-93 TRANSFUSIONS REGISTER IN HAEMATOLOGY: ESSENTIAL SUPPORT OF HEMOVIGILANCE F.Soltani; F.Kacha;A.Ounissi;H.Hamza ; S.Chichoune;H.Zidani;K.Kouidri; M.Saïdi Haematology, University Hospital, Batna, Algeria. Introduction: Transfusions are medical acts largely practised in haematology. This gesture is not divided of risks, it is recommended to make a register are listed all the transfusion of labile blood products LBP as suggested by the regulator and any anomalies encountered in upstream or downstream of the transfusion. Methods: This retrospective analysis, effected on the register taken by nurses, we have studied the datum recorded during 2009 and compared with those set down on the patient’s files. Results: During this year: 1344 LBP transfusions have been registered: 650 packed red blood cells, 540 SP(standard platelets) and 56 AD(single donor apheresis platelets) and 78 FP(frozen plasma); mean 3,6 acts / day. The major indications are acute leukaemia and aplastic anaemia. When comparing with the real transfusion reported on medical files we find that 46 transfusions were not reported (3,6 %).Only 3events are registered among 13 real. Commentaries: This work helps us to make a look on the person who is using this therapeutique procedure that seems saving but can be dangerous when all precaution were not taken. The deficiencies revealed in maintaining the register as the non-registration of some transfusion (3.6%) the results of compatibility tests and incidents encountered and are not always mentioned 3/13. Conclusion: When looking to these insufficiencies, it is essential to carry out a pedagogic work related to the blood transfusion, recapture the fundamental notions of hemovigilance the nurses well as the medical ones, also the practical application of these notions must be materialised on the transfusion register that makes an important support for traceability. 181 PO-94 EVALUATION OF ANGIOGENISIS ACTIVITY IN UNTREATED ERYTHROCYTOSIS PATIENTS C.

The angiogenic activity was evaluated by the assessment of the serum VEGF levels in 78 untreated erythrocytosis patients and 21 healthy subjects. The results indicated that VEGF was overproduced in advanced and untreated PV patients and at less degree in early PV a subgroup of idiopathic erythrocytosis, thus confirming an increased angiogenic activity. However VEGF doesn’t play an angiogenic role in secondary erythrocytosis. 182 Translation to French: PO-94 EVALUATION OF ANGIOGENISIS ACTIVITY IN UNTREATED ERYTHROCYTOSIS PATIENTS C. Maktouf1, A.

L’activité angiogénique a été évaluée par la mesure des taux de VEGF sérique chez 78 malades présentant une érythrocytose non traitée et 21 sujets sains. Les résultats ont révélé une surproduction du VEGF chez les malades atteints de la maladie de Vaquez non traitée et à moindre degré chez les patients ayant une polyglobulie primitive débutante (un sous-groupe d’érythrocytose idiopathique), confirmant ainsi une augmentation de l’activité angiogénique. Cependant l’angiogénèse est absente dans les polyglobulies secondaires. 183 PO-95 THROMBOCYTÉMIE ESSENTIELLE RÉVÉLÉE PAR UNE NÉCROSE CUTANÉE CHEZ UN SUJET JEUNE S.En-nasri,S.Nait Mbarek,H.Nafil,L.Mahmal1 I.Esqalli,O.Elatiqi,I.Abkari,F.Ait Essi,Y.Najeb,M.Latifi(2) Service d’hematologie-CHU Med VI-Marrakech-Maroc(1) Service de traumatologie orthopedique B -CHU Med VI-Marrakech-Maroc(2) La thrombocytémie est un syndrome myéloprolifératif caractérisé par une thrombocytose majeure. C’est une maladie monoclonale de la cellule souche multipotente. Elle s’accompagne d’anomalies morphologiques et fonctionnelles des plaquettes. Ce taux excessif de plaquette est souvent découvert fortuitement lors d’un examen hématologique systématique. L’âge moyen de découverte est de 60 ans, elle est très rare chez le sujet jeune surtout de sexe masculin. Nous rapportons l’observation d’un patient âgé de 28 ans, hospitalisé au service de traumatologie pour nécrose cutanée post traumatique. L’examen clinique a montré une nécrose de la face interne de la jambe, sans signe hémorragique ni hépato ou splénomégalie. Le reste de l’examen était normal. Un bilan préopératoire fait avant la nécrosectomie a montré une hyperplaquettose à 1 116 000/ mm3, Hb:8,3 g/dl ,VGM: 88fl, TCMH:28pg , Hématocrite:27%,et les globules blancs à 12 000/ul, PNN:8500/ul,Lc:1300/ul. Le bilan fait dans le cadre du diagnostic étiologique de la thrombocytose a montré une ferritinémie à 287ng/ml, et une vitesse de sédimentation à 132 mm. Le myélogramme est richement cellulaire, avec une richesse élevée en mégacaryocytes évoquant un syndrome myéloprolifératif chronique. La biopsie ostéomédullaire a montré une moelle riche avec une hyperplasie de la lignée mégacaryocytaire. Au total il s’agit d’une thrombocytémie essentielle chez un jeune homme de 28 ans. La recherche de la mutation Jack 2 en cours. Le patient était mis sous hydroxyurée avec une bonne évolution:le chiffre de plaquette actuel est de 500 000/ul. La thrombocytémie essentielle est une étiologie rare des thrombocytoses, Il n’y a pas de signe pathognomonique clinique ou biologique et le diagnostic est un diagnostic d’exclusion avec les thrombocytoses réactionnelles ou les autres syndromes myéloprolifératifs chroniques. Sa révélation par une nécrose cutanée est tres rare. 184 PO-96 SERUM ERYTHROPOIETIN LEVEL IN ERYTHROCYTOSIS C. Maktouf1, A. Bounemra2, S.Mahjoub3a, F.

Patients and Methods: This was a prospective, multicenter study on 78 patients suspected to have polycythemia (hematocrit greater than 50% in men and 48% among women).Before any therapeutic treatment (phlebotomy or chemotherapy), standardized series of investigations was done to these patients. The assays of EPO have been made from frozen serum by ELISA using a standardized commercial kit. (Quantikine; R&D Systems, Minneapolis, MN, USA) Results: According to the OMS criteria of Polycythemia, our 78 untreated patients were divided into four groups - Group 1: polycythemia vera (23M-22F ; mean age 59,3 ±13.7 years) - Group 2: idiopathic eythrocytosis (16 M ; mean age 41,1 ± 15,1 years)- Group 3: secondary erythrocytosis (14 M; mean age 53.2 ± 13,0 years) - Group 4: apparent erythrocytosis (3 M; mean age 43,6 ± 12,5 years) The serum erythropoietin level of these patients was compared to those of a healthy control group (21 M ; mean age 45,5 ± 14.7 years).The average serum level of EPO is collapsed in polycythemia vera patient group (3 ± 2.3 mIU / mL) compared to the serum EPO levels in normal controls (11.4 ± 5.9 mIU / mL). Its positive predictive value was 97.67%. This level was normal in idiopathic erythrocytosis patient (9.2 ± 4.4 mIU / mL) and in the apparent erythrocytosis patients (7.6 ± 2.1 mIU / mL) but it was higher among the group of secondary polycythemia (26.7 ± 18.2 mIU / mL). Conclusion: A lower value of serum erythropoietin guides to the diagnosis of polycythaemia vera, whereas a high value is for a secondary origin. Let the hypothesis that a group of heterogeneous entity that is the idiopathic erythrocytosis is an early form of polycythemia vera, the mechanism of the decrease of the serum EPO level during evolution is to study. 185 Translation to french: PO-96 TAUX DE L’ÉRYTHROPOÏÉTINE SÉRIQUE AU COURS DES ERYTHROCYTOSES C.

Patients et Méthodes: Il s’agit d’une étude prospective, multicentrique concernant 78 patients suspect avoir une polyglobulie (hématocrite supérieure à 50% chez les hommes et 48% chez les femmes). Ils ont bénéficié avant toute prise en charge thérapeutique (saignées ou chimiothérapie) d’une série d’explorations standardisés. Les dosages de l’EPO ont été réalisés, à partir de sérum congelé, par technique ELISA à l’aide d’un kit commercial standardisé. (Quantikine; R&D Systems, Minneapolis, MN, USA) Résultats: Selon les critères du diagnostic de l’OMS nos 78 patients non traités ont été divisés en quatre groupes - Groupe 1: polyglobulie primitive (23M-22F, âge moyen 59,3 ± 13,7 ans) - Groupe 2: eythrocytose idiopathique (16 M; âge moyen 41,1 ± 15,1 ans) - Groupe 3: polyglobulie secondaire (14 M, âge moyen 53,2 ± 13,0 ans) - Groupe 4: érythrocytose apparente (3 M, âge moyen 43,6 ± 12,5 ans). Le niveau de l’érythropoïétine sérique de ces patients a été comparée à celles d’un groupe de témoins normaux (21 M, âge moyen 45,5 ± 14,7 ans). Le taux sérique moyen de EPO est effondré au cours de la polyglobulie de vaquez il est de 3 ± 2.3 mUI/mL comparativement au taux de EPO sérique chez les témoins normaux (11.4 ± 5.9 mUI/mL). Sa valeur prédictive positive est de 97.67%. Ce taux est normal au cours des polyglobulies idiopathiques (9.2 ± 4.4 mUI/mL) et au cours des fausses polyglobulies (7.6 ± 2.1 mUI/mL) Cependant il est élevé chez le groupe des polyglobulies secondaires (26.7 ± 18.2 mUI/mL). Conclusion: Une valeur basse de l’érythropoïétine sérique oriente vers le diagnostic de la polyglobulie primitive alors qu’une valeur élevée est en faveur d’une origine secondaire . Admettons l’hypothèse qu’un groupe de l’entité hétérogène qu’est l’érythrocytose idiopathique est une forme débutante de la polyglobulie primitive, le mécanisme de la baisse de érythropoïétinémie au cours de l’évolution est à étudier. 186 PO-97 RESULTS OF THE HEMOGLOBIN ELECTROPHORESIS DURING A PERIOD OF TWO YEARS IN LABORATORY OF HEMATOLOGY H.Otmani1; I.Rahal1; F.Z. Néche1; A.Boumlit1; M. Saidi2. 1Laboratory of Hematology; Hematology, University Hospital; Batna, Algeria. Introduction: The hereditary defects in the synthesis of hemoglobin, are the most common severe monogenic diseases. Thalassemia and sickle cell disease represents a serious public health problem given its frequency and difficulty to take of charge the patients. In Algeria 2% of the population of β thalassemia heterozygotes, 10% of newborns have a trait of α thalassemia and many parts in Algeria have a high frequency of hemoglobin S. Materials and methods: Study made during a period of two years (marsch2008-march2010) in Hematology Laboratory on 328 subjects to detect the abnormal hemoglobin on electrophoresis. The hemoglobin electrophoresis was done for cellulose acetate and by Capillarys Sebia system. Result: The results of the hemoglobin electrophoresis performed on 328 subjects, we are found 71 (21.64%) abnormal electrophoresis,which are: - 09 (12,6) β+ thalassemia homozygote, - 40(56.3%) β thalassemia heterozygotes) - 09 (12,6%) hemoglobin S (sickle cell disease) - 09 hemoglobin C, - 01 hemoglobin H and 1 hemoglobin O Arabic, - 02 decrease Hb A2, related with iron deficiency. Conclusion: We can say that β thalassemia, hemoglobin S, hemoglobin C are most frequent of all abnormal hemoglobin in this region.It’s necessary to program an epidemiological study to assess exact prevalence of these different defects. 187 PO-98 HÉMORRAGIE CÉRÉBRALE ET MÉNINGÉE AVEC UN HÉMATOME SOUS DURAL SPONTANÉS CHEZ UN ENFANT PORTEUR D’UNE HÉMOPHILE A MAJEURE S.En-nasri, S.Nait M’barek, H.Nafil, L.Mahmal Service d’hématologie,CHU Mohammed VI,Marrakech,Maroc L’hémophilie A est une anomalie constitutionnelle de la coagulation sanguine en rapport avec un déficit du facteur VIII de la coagulation. Elle est dite majeure lorsque le taux du facteur VIII est inférieur à 1 %. Cette pathologie est responsable d’hémorragies cérébrales sévères pouvant entraîner des manifestations cliniques invalidantes menaçant le pronostic vital. L’hémorragie cérébrale spontanée est une complication très rare, elle représente seulement 2 % des complications hémorragiques chez l’hémophile. Nous rapportons le cas d’un enfant hémophile âgé de 11 ans avec un taux de facteur VIII à 1%, ayant deux frères hémophiles, qui a présenté d’une façon brutale et atraumatique un syndrome d’hypertension intracrânienne. L’examen clinique n’a pas noté de déficit neurologique ni d’hématome ou de lésion traumatique du cuir chevelu. la TDM cérébrale a objectivé un hématome sous dural temporal gauche, deux foyers hémorragiques temporal et pariétal gauches avec une hémorragie méningée, sans anomalie vasculaire sous jacente. L’artériographie n’a pas été réalisée. Le patient a été traité par le facteur VIII recombinant à la dose de 16 UI/kg en une seule prise par jour pendant 5 jours. L’évolution a été marquée par la disparition des signes cliniques au bout de 6 jours. Le scanner cérébral de contrôle à J7 a montré une régression de l’hématome sous dural ainsi que des foyers hémorragiques et de l’hémorragie méningée. La littérature préconise une posologie du facteur VIII en fonction de la sévérité de l’accident hémorragique selon la formule suivante: Nombre d’unité nécessaires est égale au poids corporel (kg) multiplié par l’augmentation souhaitée du taux de facteur VIII (% de la normale) x 0.5 Dans les hémorragies cérébrales on vise un taux de facteur VIII entre 60 % et 80%,ce qui donne à notre patient une posologie de 40 UI/kg, dose qui est supérieure à celle administrée au cas étudié. L’hémophilie est une étiologie des hémorragies intra cérébrales à connaitre, bien que rare, nécessitant une approche thérapeutique personnalisée, qui permettra la réduction des doses du facteur VIII qui est très onéreux et au dessus des bourses de nos malades 188 PO-99 RHABDOMYOSARCOME PARATESTICULAIRE S.En-nasri,S.Nait Mbarek,H.Nafil,L.Mahmal Service d’hematologie.CHU Med VI.Marrakech,Maroc Le rhabdomyosarcome (RMS) est une tumeur mésenchymateuse maligne,rare, caractérisée par la présence des cellules identifiables aux rhabdomyoblastes.Il s’ agit d’une tumeur intra scrotale localisée aux structures para testiculaires:vaginale, épididyme ou cordon spermatique. Le diagnostic est histologique.Il existe plusieurs formes dont la plus fréquente est l’embryonnaire qui se voit chez l’enfant.Le pronostic est mauvais et le traitement repose sur l’association de la chirurgie, la chimiothérapie et la radiothérapie . Nous rapportons le cas d’un enfant de 2 ans et 9 mois, sans antécédents pathologiques particuliers, qui a présenté une grosse bourse droite indolore, évoluant de façon progressive depuis 2 mois avec altération de l’état général. L’examen clinique trouve une masse scrotale droite dure, non douloureuse à la palpation et sans signes inflammatoires.Le reste de l’examen clinique est sans particularité. L’échographie scrotale avait montré une masse tissulaire scrotale droite hétérogène aux dépens de parenchyme testiculaire et du cordon spermatique.L ‘échographie abdominale, radiographie du thorax, le bilan biologique sont normaux. L’intervention a consisté en orchidectomie totale avec ligature haute du cordon par voie inguinale. L ‘étude histologique de la pièce opératoire a conclu à un rhabdomyosarcome embryonnaire type I.Une chimiothérapie complémentaire (VAD, VAC) est en cours.L’ évolution a été marquée par une rémission complète. Le RMS para testiculaire est une tumeur rare, elle nécessite un diagnostic précoce et un bilan d’extension précis.Le traitement est bien codifié et c’est grâce à l’association chirurgie, polychimiothérapie et radiothérapie que le pronostic s’est nettement amélioré.Une surveillance adéquate à long terme doit être instauré afin de détecter les rechutes qui sont généralement fatales 189 PO-100 MICROBIOLOGICAL SAFETY OF BLOOD COMPONENTS DURING STORAGE M Khalil, A Jebriel Department of Transfusion Medicine, Misurata oncology institute Misurata Libya Purpose: Because of conflicting result in the literature we studied the microbial safety of blood during shelf life. Methods: Blood bags from 121 blood donors were drawn by venous puncture. The whole blood was separated using 3 bags system (Biotrans NPBI), into erythrocytes, Buffy coat (BC) and plasma. BC was stored at 4C. Samples were taken by sterile-docking on day 1, 3, 6, 35, and 42 in 150 ml transfer bag. From this material was taken by a syringe and 5 ml each were inoculated into culture flasks (Bactec plus Aerobic/F an Anaerobic/F; Becton Dickinson). Before inoculation, the rubber membranes of the flasks were disinfected with Cutasept F (Bode Chemie). Bacterial growth of a total of 1210 samples was monitored for seven days in a Bactec 9120/9240-analyzer. In addition on day 1 CRP was also measured in the BC material. Results: The CRP was normal in all BC»s. In contrast, 3BC samples contained bacteria, while no bacteria were found in 1204 (99.5%) of the BC samples tested. All positive BC samples contained Staphylococcus species: 1 Staph. epidermidis (storage day 3). 1. Staph. hominis (storage day 35) and 1 Staph. capitis (storage day 35) Because of the positive results, a second samples was taken from the three original BC»s and Retested for microbial Contamination. These samples showed no bacterial growth, though the positive results were due to secondary contamination during the inoculation procedure. So, all Blood bags could be released for transfusion. Conclusions: Blood bags are microbiologically safe for up to 42 days storage. All contaminations detected belonged to the skin flora. They proved to be secondary and occurred during the inoculation procedure. So it is of utmost importance to avoid these secondary contaminations in microbiological testing of blood products. 190 PO-101 ALLOGENEIC HEMATOPOIETIC STEM CELLS TRANSPLANTATION (HSCT), FROM HLA IDENTICAL SIBLING DONORS, FOR 20 PATIENTS WITH PAROXYSMAL NOCTURNAL HEMOGLOBINURIA (PNH) R. Ahmed Nacer, F. Mehdid, F. Harieche, M. Benakli, R. Belhadj, N. Rahmoune, M. Baazizi, D. Aitouali, M.Ouzeghdouh , S.Abderrhmani, F. Zerhouni, RM. Hamladji Department of Hematology and BMT unit, Pierre and Marie Curie Center, Algiers, Algeria Introduction: Paroxysmal nocturnal hemoglobinuria is a haematological disorder characterized by the clinical triad of intravascular hemolysis, marrow failure and venous thrombosis. HSCT is a treatment of choice for marrow failure form and also for recurrent hemolysis and thrombophilia after Eculizumab treatment failure. Material and méthods: From April 2005 to November 2009 (59 months period) 20 patients (pts) with PNH in aplastic form underwent allogeneic HSCT from HLA identical siblings donors; median age 23,7 years (range 15 to 34); sex-ratio (M/F) 3; median interval from diagnosis and transplant 16,3 months (range 2 to 120); 3 pts received more than 20 transfusions before allograft. Diagnosis was performed by flow cytometry. All pts received conditioning regimen with chemotherapy alone: 17 with cyclophosphamide (Cy) alone at dose 200 mg/Kg BW and 3 pts with association of procarbazine 37.5 mg/Kg, Cy 200 mg/Kg and ATG (Fresenius) 40 mg / Kg. GVHD prophylaxis associated methotrexate and cyclosporin (Seattle protocol). All pts were grafted with peripheral blood stem cell and 21 grafts (within one boost) were used for 20 pts: median CD34+ cells 4.52 x 106 / Kg BW (range 1.83 to 8.84). Chimerism was studied for 18 pts by STR-PCR method. At February 2010 maximal follow up is 59 months ant minimal 4 months. Résults: The median time to engraftment was 14 days (11 to 19). Seventeen pts are alive (85%) within 16 pts (80%) with success engraftment after median follow up 17 months (range 4 to 59); median chimerism donor at D30: 98, 3%, at D60: 100% and at D100: 100%. Acute GVHD occurred in 8 pts (40%) with grade II-IV and chronic GVHD in 4 patients (23, 5%) which 2 extensive. Graft failure was observed and confirmed by chimerism study in 2 pts: one pt recovered hematopoiesis occurring after boost without conditioning and the second pt is alive with cyclosporin treatment and less frequent transfusion. Three pts died (15%) by transplant related mortality (TRM): Acute GVHD. The actuarial overall survival (OS) is 84% at 54 months. Conclusion: Our study concerns a small cohort and shows a good results with TRM: 15% and OS: 84%. Our results seem better than literature (OS: 50-60%) and it should be confirmed by long term follow-up and a biggest cohort. 191 PO-102 ALLOGENEIC HEMATOPOIETIC STEM CELL TRANSPLANTATION (HSCT) IN CHRONIC MYELOID LEUKAEMIA (CML): LONG TERM RESULTS M.Benakli, R. Ahmed Nacer, A. Talbi, F. Mehdid, R. Belhadj, M. Bazizi, N. Rahmoune, F. Harieche, F. Zerhouni, RM. Hamladji Hematology-BMT Unit, Pierre and Marie Curie Center, Algiers, Algeria Background: Allogeneic HSCT is recognized as being the only effective treatment in the CML with cure. We report our experiment of this procedure with a comparative study between myéloablative and reduced intensity conditioning regimen. Material and methods: From July 98 to June 2009, 274 patients (pts) with CML underwent allogeneic HSCT with HLA identical sibling donors. The myeloablative stem cell transplantation (MST) based on Tushka protocol was employed in 101 pts including 56 in first chronic phase(CP), 39 in accelerated phase (AP) and 6 in blast crisis(BC). The prevention of the graft versus host (GVHD) associated ciclosporine and méthotréxate according to Seattle protocol. The non myeloablative SCT (NST) based on the use of Fludarabine and Busulfan was employed in 173 pts including 149 pts in first CP and 24 in AP. The GVHD prophylaxis consisted of cyclosporine with mycophenolate mofetil. The median age of the pts at transplant for MST and NST is 24 years (4-44) and 36 years (1855) respectively with a significant difference (p<0,01). The sex-ratio is 1,2 and 0,96 respectively; interval diagnosis was longer in MST pts: 15 months (3-82) than in NST pts: 11 months (4-58) (p<0,01). The grafts used are peripheral blood stem cells (MST=90, NST=173), bone marrow (9 MST) and umbilical cord blood (2 MST). Results: Aplasia is occurred in 76 pts (44%) NST group and all pts of MST group (100%), (p<10-8). The incidence of acute GVHD was the same in the MST and NST group (p=0,35) with respectively 48 pts (47,5%) and 72 pts (42,8%). The incidence of chronic GVHD was also the same (p=0,14), 58 MST pts (63,7%) and 114 NST pts (71,2%). The cytomegalovirus (CMV) infection was seen in 23 MST pts (22,7%) and 28 NST pts (16%) without significant difference (p=0,16). Relapse of disease occurred in 15 MST pts (14,8%) and complete remission was obtained in 5 pts ( immunosuppression discontinuation:1, DLI: 2 and Imatinib: 2); In the group NST 31 pts relapsed (17,9%) and in 15 pts remission obtained after salvage treatment (immunosupression discontinuation: 8, DLI: 3 and 2d myeloablative allograft: 4) (p=0,7). At December 2009, 56 MST pts (55,4%) and 109 NST pts (63%) are alive with a median follow-up in 69 months and 64 months respectively. The Overall Survival (OS) is 41,9% for the MST group and 56,8% for NST group (p<0,001); Event 192 Free Survival (EFS) is 36,7% and 49,5% respectively with significant difference (p<0,001). Conclusion: No differences were observed between MST and NST group concerning acute and chronic GHVD, CMV infection and incidence of relapse. However in long term results, OS and EFS are better in NST group than MST group. 193 PO-103 PROSPECTIVE VALIDATION OF A NOVEL MYELOABLATIVE CONDITIONING REGIMEN: FLUDARABINE - IV BUSULFAN, IN 38 PATIENTS WITH ACUTE MYELOID LEUKEMIA(AML) A.Talbi, R-M Hamladji, M.Benakli, R. Ahmed-Nacer, R.Belhadj, F.Mehdid, N.Rahmoune, F.Harièche, F.Zerhouni Hematology-Bone marrow transplantation unit, Pierre and Marie Curie center (CPMC), Algiers Algeria Introduction: Allogeneic hematopoietic stem cell transplant (HSCT) has the goal of inducing a graft versus tumor immune effect, however the choice of the conditioning may have an impact on the overall out come, in fact more intensive regimens can cause greater morbidity and mortality, on the other hand the reduced intensity conditioning (RIC) may have less anti tumor effect. In this study we used a conditioning regimen with Fludarabine (FLU) and IV Busulfan (BU) at myeloablative dose. Material and methods: Between February 08 and June 09, 38 Adults pts with AML received a geno identical allogeneic peripheral blood HSCT, with FLU (200mg/m²) and one daily iv BU (12,8mg/Kg) total dose conditioning; the median age is 35 years (22-55), the sex ratio is 1,9 (25/13); the cytologic types of AML (FAB: M1=12, M2=16, M3=1, M4=2, M5=5, M6=2); 31HSCT were performed in first remission (81,5%), 5 in second remission, and 2 in relapse. The median time from the diagnosis to transplant is 4,4 months (2-10), GVHD prophylaxis associated ciclosporin and methotrexate (Seattle).. At September 2009, maximal follow up is 17 month, and minimal 3 month. Results: The overall median time to achieve a neutrophil count > 0,5x109/L was the day 14 (9-18), and a platelet count > 20000 was the day 13 (8-16); the median duration of the neutropenia is 9 days (1-16). Six pts (16,2%) have a CMV reactivation at day 98 (40-210) Acute GVHD was observed in 10pts (27%), (Grade II=4, grade III=2, grade IV=4). Chronic GVHD was observed in 11pts (34,4%), severe cGVHD: 10pts. Four pts (10,8%) relapsed, at a median time of 192 days (102 330), 2pts were in 1st CR, and 2pts in 2nd CR, none of these pts have presented GVHD. Eight pts (21%) died; 4pts after aGVHD; 2 after relapse, 1 after unknown extra hematological cause, and the last one was a graft failure. At one year, TRM was about 10,8%. Thirty pts (84,2%) are still alive; 28 pts(73,6%) are in complete remission; 2 pts are alive in relapse. The median following is 7 (3 - 17). Overall survival and DFS are respectively 74,5 and 64,4%. Conclusion: This study show that FLU-BU myeloablative regimen causes limited hematological and extra hematological toxicity; it can be successfully used in older pts. The rate of relapse seams not higher than what we observed with other myeloablative conditioning regimen (12,8% in CPMC study EBMT 08, 37% GOELAM –Blood 97. 194 PO-104 MYELOPROLIFERATIVE DISORDES IN TRIPOLI Kalthoum Elwaer, Abukris Alwindi Department of Oncology and Hematology, Tripoli Medical center, Tripoli, Libya Department of Oncology and Hematology, Tripoli Medical center between January 2007 to March 2010. Polycythemia rubra vera [PRV] was by far the commonest disorder representing 46% of the cases. Splenomegaly or hepatosplenomegaly was present in 31% of patients with polycythemia rubra vera and in 100% of patiens with myelofibrosis, 22% of patients with essential thrombocythemia had splenomegaly. Patients with PRV tended to be older than patients with essential thrombocythemia of myelofibrosis. The median age of PRV patients 60 years, essential thrombocythosis 53.5, and myelofibrosis 50 years. JAK2 mutation was looked for in 15 patients. All six patients with PRV tested positive as were the three patients with otherwise non specified MPD. Half of the patients with essential thrombocythosis tested positive for the JAK2. 195 PO-105 HISTIOCYTOSE LANGERHANSIENNE(HX) GRAVE CUTANEOSPLENIQUE S.En-nasri,S.Nait Mbarek,H.Nafil,L.Mahmal Service d’hematologie.CHU Med VI.Marrakech,Maroc L’histiocytose X (HX) ou histiocytose langerhansienne est définie par la prolifération de cellules mononuclées qui renferment des granules de Birbck intracytoplsmiques et qui présentent a leur surface les marqueurs antigéniques CDIa et la protéine S100.Touchant l’enfant et l’adulte jeune c’est une maladie de spectre clinique très divers,allant du simple granulome éosinophile a la forme grave multi viscérale avec dysfonctionnement d’organe.sa prise en charge thérapeutique est encore aujourd’hui controversée. M .H âgé de 18 mois présentant un syndrome anémique et hémorragique (purpura en maillot de bain)avec splénomégalie débordant l’ombilic depuis 6 mois,le tout dans un contexte de fièvre et d’altération de l’état général.le myélogramme fait était normal ,la biopsie des lésions cutanées a posées le diagnostic d’hystiocytose X.le dosage des marqueur CD n’a pas été fait. Dans notre cas il s’agit de la maladie de Letterer-Siwe qui présente une forme de l’histiocytose du nourrisson associant l’altération de l’état général et l’atteinte cutanée et multi viscérale (splénique essentiellement). Le cumul de facteurs de mauvais pronostic (classification de Lahey-Osband) ont compromis l’effet des différents protocoles de chimiothérapies utilisées rendant inéluctable le décès de la patiente. La nécessité d’avancer dans la compréhension de la pathogénie de cette maladie, et la diversité du traitement et de la prise en charge des enfants atteints justifient la réalisation d’un protocole de diagnostic et de traitement multicentrique, qui pourra permettre de rationaliser les attitudes thérapeutiques et d’améliorer le pronostic des formes graves. 196 PO-106 THROMBOPHILIE ET DRÉPANOCYTOSE M.Chekkal. K.Moulassedoun. M.C.A Rahal.F.Seghier Service d’Hémobiologie.CHU d’Oran. Algérie. Notre étude a été réalisée au niveau du service d’hémobiologie du CHU d’Oran sur une période de 07mois s’étalant du mois de novembre 2008 au mois de mai 2009. Elle a concerné 40 patients atteints de la drépanocytose dont 11 sont homozygotes, 10 hétérozygotes composites S/β°thal et 19 hétérozygotes en dehors de toute crise vaso- occlusive en ne recevant aucun traitement interférant avec le bilan de thrombophilie. Nous avons recherché l’existence d’un processus thrombotique aggravant la maladie drépanocytaire par le dosage des inhibiteurs physiologiques de la coagulation (protéine C, protéine S libre et antithrombine), dosage du facteur VIII de la coagulation et par la recherche des anticorps antiphospholipides. Les résultats obtenus sont les suivants: • Déficit en protéine C chez 45,4% des homozygotes, 33,3% des composites S/βthal et 5,2% des hétérozygotes. • Déficit en protéine S chez 54,5% des homozygotes, 33,3% des composites S/βthal et 5,2% des hétérozygotes. • Déficit en antithrombine 27,2% des homozygotes alors que les composites S/βthal et les hétérozygotes ne présentent pas de déficit. • Augmentation du taux du facteur VIII de la coagulation chez 100% des homozygotes, 44,4% des composites S/βthal et 31,5% des hétérozygotes. • La recherche des anticorps antiphospholipides de type lupique est négative chez tous les malades. Ces anomalies de l’hémostase traduisent donc l’existence d’un état pro thrombotique au cours de la maladie drépanocytaire qui favoriserait la survenue d’accidents vaso- occlusifs. Le Facteur VIII de la coagulation constamment élevé chez les drépanocytaires peut ainsi constituer une cible thérapeutique privilégiée dans le traitement des manifestations thrombotiques de la maladie. 197 PO-107 THE INTERMEDIATE THALASSEMIAS Zatla L,Elalia H, Bousmaha N, Charef l,Boudjoras YA, Sfaoui W, Rahal Y,Touhami H Division of haematology, CHUoran, Ageria Introduction The thalassemias are hemolytic anemia of varying severity: asymptomatic intermediate or severe. The thalassemia intermedia is a heterogeneous group of thalassemia whose molecular mechanism is complex with multiple genotypes and phenotypic expression variable: severe or asymptomatic. The major criteria for lediagnotic of the thalassemia intermedia are the late age of onset (> 2 years), anemia (Hb = 7 to 10 g / dl) microcytic, not transfusion dependent splenomegaly consistent with varying facial dysmorphia. Our objective is to make a focus on our patients with a review of the literature. Patients and methods: 72 thalassemia syndromes are followed by the Division of Hematology adult: 11 thalassemia major, thalassemia intermediate 4 and 18 S beta. The 4 patients with thalassemia intermediate (TI) of sontags respectively 20,21,40, and 41 years including 3 sisters.a retard is found in a patient who is not their brother, moderate splenomegaly is constant, facial dimorphism in a patient. There is no infectious or immunological complication. Three are transfused occasionally but the sister was transfused once a month (bleeding). Three patients received chelating. Discussion IT are classified into three groups: IT fairly moderate TI moderate enough IT Severe complications are frequent thrombophilia after splenectomy, cardiac complications 20% extramedullary hematopoiesis, leg ulcers of 20 to 30% endocrinopathies rare late, osteoporosis and hypersplenism late. Treatment of IT based on episodic late transfusions, their indications are hypersplenism extramedullary hematopoiesis and heart failure. Splenectomy is indicated if hypersplenism and if transfusion requirements increase. Conclusion The B thalassemia intermediate is a very heterogeneous group.Its treatment varies depending on the phenotype of transfusion with minimal or splenectomy if hypersplenism. 198 PO-108 PREVALENCE OF JAK2-V617 MUTATION IN ALGERIAN PATIENTS WITH MYELOPROLIFERATIVE DISORDERS N. Benchikh(1), A. Messaoudi(1), M. Nachi(1), C. Belarbi(1), R. Moussaoui(1), A. Bekadja(2), M. Brahimi(2), A. Arabi(2) (1)Department of Biochemistry, EHU 1er Novembre Oran, Algeria. (2)department of hematology, EHU 1er Novembre Oran, Algeria. Aims An acquired mutation of the Janus Kinase 2 gene (JAK2) which involves a Valin substitution by Phenylalanine in position 617 is implied in the pathogenesis of myeloproliferative disorders [1, 2, 3, 4]. The aim of our study is to detect this mutation among patients with myeloproliferative disorders in western areas of Algeria. Material and methods: This study focused on 77 patients, recruited in various departments of hematology from the west of Algeria. The mutation was detected by Amplification Refractory Mutation System – Polymerase Chain Reaction (ARMS-PCR) [5]. Results: The prevalence of V617F JAK2 mutation in polycethemia vera, essential thrombocytemia, primary myelofibrosis and myeloid splenomegaly are respectively:81,48%,45%,66,66% and 40%. This mutation was not found in atypical SMP, in secondary polyglobuly or thrombocytosis, and in chronic myeloid leukemias. Conclusions: Our study is the first to evaluate the JAK2 V617F mutation among patients with myeloproliferative disorders in the west of Algeria. Our results confirm that JAK2 V617F mutation is specific, but unequally found in myeloproliferative disorders. 199 PO-109 PLATELET TRANSFUSION REFRACTORINESS AND ALLOIMMUNIZATION IN PATIENTS WITH ONCOLOGIC BLOOD DISORDERS H.

France (3) Service d’Hématologie. CHU Dorban Annaba. Algerie Introduction: Platelet transfusions are effective therapy for hemorrhage in thrombocytopenic patients. A major complication of multiple transfusions is still platelet transfusion refractoriness. Despite most cases are secondary to non-immune causes (80%), the most severed cases are associated with alloimmunization. The prevalence and consequences of HLA and HPA antibodies in that setting are unknown in Algeria. Aim: To prospectively determine clinical and laboratory factors affecting the post-transfusion platelet increment, frequency and characteristics of post transfusion alloimmunization. Patients and methods: Patients with recently diagnosed leukaemia and undergoing chemotherapy requiring multiple transfusions were included in that study. Antibodies against the platelet glycoproteins GPIaIIa, GPIIbIIIa, GPIbIX and anti-HLA classe I were identified with a monoclonal antibody-specific immobilization of platelet antigens technique (MAIPA). Results: HLA antibodies were found in 30 cases (28.55%), and specific platelet antibodies in 6 of 105 patients (5.71%). Among these six patients, 5 contained additional HLA antibodies. The following platelet-specific antibodies were identified: anti HPA-1a (n=2), anti HPA-1b (n=2), anti HPA-5b (n=1) and anti HPA-3a (n=1). The prevalence of platelet alloimmunization in Algeria is higher than the prevalence found in Europe (< 4%) but lower than the prevalence found in Asia (20-26%). Six sera contained panreactive antibodies against platelet glycoproteins (GP): anti-GP IIbIIIa (n=3), anti-GP IaIIa (n=1) and anti-GP IbIX (n=2). Platelet refractoriness appeared in 31/47 receiving only platelet transfusions: 6 cases (19.35%) with alloimmunization (4 cases with antiHLA antibodies, 1 case with anti-HPA antibody and 1 case with both HLA and HPA antibodies), 17 cases (54.83%) with non-immune platelet consumption and 19 cases (61.29%) with insufficient dosing of transfused platelets. 200 Conclusion: Platelet transfusion refractoriness is a major complication of long-term platelet supportive care and may lead to fatal bleeding complication in thrombocytopenic patients. HPA antibodies play a minor but relatively important role in patients with HLA antibodies. In case of HLA and/or HPA alloimmunization associated with refractoriness, matched platelet transfusions are indicated. 201 PO-110 TOXOPLASMA AND CMV SERO-PREVALENCE IN THE BCIDI COHORT OF PATIENTS Amina Abusedra & Fatma Najem Background: Toxoplasmosis and Cytomegalovirus (CMV) are important pathogens which contribute to the morbidity and mortality associated with HIV disease. Sparse data are available concerning the prevalence of these two diseases in Libya The objective our study was to evaluate the seroprevalence of toxoplasmosis and CMV in the cohort of HIV patients of the BCIDI. Method A cross sectional study among the BCIDI cohort was conducted between June and December 2009. All patients from the BCIDI cohorts were susceptible to be screened if attending the center during this period. The samples were serologically tested to detect the presence of antibodies of Toxoplasmosis Gondii and/or CMV using the ELISA linked florescent assay (ELfA) techniques according to the manufactur`s instructions VIDAS. All data needed for this study was extracted from the Medical Information System (MIS) of the BCIDI. Analysis was performed on SPSS. Results: Three hundreds thirty six patients were tested for toxoplasmosis out of whom 240 were less than 15 years old (71.4%) and192 were male (57.1%).Three hundreds forty three patients were tested for CMV, out of whom 266 were less than 15 years old (80.6%) and 195 were male (56.9%) We found overall seroprevalences of 13.2 % for toxoplasmosis and 91.5% for CMV. For toxoplasmosis, the seroprevalence is higher in adults than in children (11.7% vs 27.1%, p<0.001) and in female compared to male (20.1 vs 13.0, p=0.08). The seroprevalence of CMV varies slightly depending of the age and the sex but globally it is very high in the overall cohort ranging between 88 and 96%. Discussion and conclusion This study is one of the first studies performed in Libya assessing the level of infection of two common HIV co-infection. It might be useful to confront these results with estimation done in other places of Libya. The result of our study might help to guide the clinical management of the BCIDI patients. 202 PO-111 ACQUIRED APLASTIC ANEMIA: EXPERIENCE OF THE HEMATOLOGY DEPARTMENT OF CASABLANCA A.Hmimech; N.Khoubila; F.Merimi; A.Quessar; S.Benchekroun Service d’hématologie et oncologie pédiatrique de Casablanca, Maroc Introduction: Aplastic anemia is defined as a quantitative bone marrow failure secondary to partial or complete loss of hematopoietic tissue, without abnormal tissue proliferation. This is a rare disease, whose etiology is found in only 20% of cases. Few studies have been conducted in Morocco, but it is a serious disease, hence the difficulty of care. The purpose of this study is to evaluate the epidemiological, clinical, biological and therapeutic of aplastic anemia collected at the Hematology department of Casablanca over 11 years. Patients and methods: Were excluded from the study all congenital aplastic anemia. All patients underwent a bone marrow biopsy, confirming the diagnosis of aplastic anemia. The rest of paraclinical assessment included a complete blood count (CBC) with reticulocyte assay, the viral serology (HCV, HIV and HbS), radiographs, immunophenotyping of peripheral lymphocytes (CD55, CD59). The severity of aplastic anemia was judged by the criteria of Camitta. Treatment options were, symptomatic treatment, no drug therapy with monitoring, androgens, cyclosporin A, antilymphocyte serum + cyclosporine. The therapeutic choice depends on the severity of the disease and the average patient. The criteria of response to treatment were complete remission (Hb> 11 ANC> 1500 Platelets> 100 000), partial remission (Hb> 8 ANC> 500 Platelets> 20 000), and treatment failure. Results: 267 cases were collected between January 1999 and December 2009. The sex-ratio H / F was 1, 2. The mean age was 32 years (4-79 years). The mean delay to diagnosis was 2 months (10 days -24 months). The bone marrow failure syndrome was complete in 63% of cases; a hemorrhagic syndrome was found in 86% of cases and was severe in 13% of cases. The aplastic anemia was severe in 56% cases, very severe in 13% of cases and not severe in 31% of cases. The aplastic anemia was idiopathic in 86% of patients, associated with the use of drugs in 4% of patients, with toxicity in 5% of patients, post tuberculosis in 2% of cases, post hepatitis in 2% of patients and associated with paroxysmal nocturnal hemoglobinuria in 1 % of patients. 162 patients were treated, of which 62.5% by cyclosporin A, 28% by androgens, 9% with cyclosporine 203 + anti-lymphocytic serum, only 1 patient received allogeneic bone marrow transplantation. 22 patients have received treatment for 2nd line, including 8 by cyclosporin A, 4 by anti-lymphocyte serum + cyclosporine and 10 by androgens. At a mean of 30 months, 13% of patients were in complete remission, 23% in partial remission, 36% failed, 15% were lost to follow and 13% died (8 due to septic shock, 13 with hemorrhagic shock). Conclusion: The frequency of aplastic anemia is difficult to assess in Morocco. It mainly affects young adult males (20-30yr). Its treatment is difficult in our context because of the existence of a single hematology service in Morocco and the high cost of treatment, hence the need to standardize its care. 204 PO-112 LYMPHOME MALIN NON HODGKINIEN LOCALISATION OSSEUSE CHEZ UNE PETITE FILLE DE 3 ANS À PROPOS D’UN CAS R.Mecifi, M.Brahimi, M Dib, M. Daouadji, M.Djebour, Centre Anti Cancer Emir Abdelkader, Algeria Introduction: Le lymphome osseux est rare chez l’enfant, sa traduction clinique et radiologique est celle d’une lésion tumorale lytique, localisée sur la métaphyse des os long ou le squelette axial [1]. Les lymphomes malins se distinguent des leucémies de l’enfant par la quantité de blastes dans la moelle osseuse qui est < 25% [2]. Nous rapportons le cas de la petite fille lynda âgée de 3ans, l’unique fille d’un couple jeune en bon état de santé, consanguin au 1er degré, admise à notre service pour la prise en charge d’un LMNH localisation osseuse (métaphyse du tibia droit). Le début remonte à quelques mois avant le diagnostique, par une douleur osseuse de la jambe droite, associé a une boiterie, plusieurs consultations avec traitements symptomatiques mais sans réponse favorable, devant l’apparition d’une tuméfaction du1/3 < de la jambe droite, un scanner a été demandé qui a montré une lésion lytique de la métaphyse du tibia droite, avec une réaction périostée; posant l’indication d’une biopsie osseuse, l’étude histologique faite par Pr MAALEM de CHU d’Oran confirme qu’il s’agit d’un lymphome osseux. Bilan d’extension retrouve un envahissement médullaire entre26% à 33%. Bilan biologique: LDH élevé 3 fois la normale. CALCEMIE légèrement augmenté / à son age. La petite été mise sous protocole (des leucémies) EORTC58881 risque très élevé L’évaluation de la maladie après un mois de traitement été marquée par une rémission médullaire a 3% de blastes, cliniquement reprise de la marche, biologiquement normalisation de la calcémie et le taux de LDH ce qui nous a poussé à continuer avec le même protocole. A mi chemin de la phase intermédiaire, on a remarqué la reprise de la boiterie et la douleur du membre inférieur, une scintigraphie osseuse faite qui retrouve une fixation condensante au niveau de la zone d’appel. Ceci à justifier une mauvaise réponse à EORTC58881 et la petite Lynda est mise sous protocole LMB89 groupe C thérapeutique. Objectif: Le but de cette présentation est d’exposer un vrai problème diagnostique et thérapeutique: - 1/ S’agit t’il d’un lymphome osseux avec envahissement médullaire ou d’une leucémie avec métastase osseuse ? -2/ Faut t’il le traiter selon le protocole des lymphomes risque élevé (groupe C), ou 205 Protocole des leucémies risque élevé ? Coclusion: Le lymphome malin non hodgkinien a localisation osseuse est rare, difficile à prendre en charge, le risque de rechute est plus élevé que dans les autres localisations. Dans notre cas, l’envahissement médullaire est supérieur à ce de la littérature. En revanche le résultat du scanner de contrôle après les deux phases thérapeutiques ne montre pas une bonne réponse osseuse au traitement. 206 PO-113 EVALUATION DU PROTOCOLE MDH 90 CHEZ L’ENFANT CANCÉREUX AU CENTRE EMIR ABDELKADER ORAN R.Mecifi, M.Brahimi, M Dib, M. Daouadji, M.Djebour, Centre Anti Cancer Emir Abdelkader Introduction: Le Centre Emir Abdelkader « CEA » est le seul centre anti-cancer pédiatrique de l’ouest Algérien. Notre centre a recruté environ 230 nouveaux cas de cancer pédiatrique pendant l’année 2009. La maladie d’hodgkin est une hémopathie maligne du tissu lymphatique particulièrement rare chez l’enfant, elle représentait en l’an 2000 selon Benammar et coll. 7% du recrutement du CEA soit en moyenne 9 nouveaux cas par an. Le but de ce travail est de présenter les aspects épidémiologiques et d’évaluer le protocole MDH90. Materiels et methodes: Il s’agit d’une étude rétrospective et descriptive sur une période de 54 mois (janvier 2004 à juin 2008) portant sur des enfants âgés de moins de 15 ans suivie au sein du CEA pour maladie d’Hodgkin. Support de travail: fiches de collectes comportant l’âge, le sexe, l’origine géographique, les signes cliniques et para cliniques ainsi que la prise en charge thérapeutique. Resultats: 40 nouveaux cas en 5 ans soit 10 cas par an L’age des enfants varie de 3 à 15 ans avec une médiane de 9 ans Le sex ratio= H/F = 4.5 La médiane de survie globale à 5 ans est de 81% Conclusion: Les résultats de notre étude étaient comparables à ceux qui sont rapportés dans la littérature. 207 7th Magharebian Congress of Hematology (MCH-7) 21st to 23rd May 2010, Zawia Jewel Hotel, Libya ORGANIZED BY UNDER AUSPICES OF General Peoples Committee of Health and Environment SPONSORED BY
