About 1% of the world’s population is affected by rheumatoid arthritis. According to recent data, 1.3 million people in the United States are reported to be affected by rheumatoid arthritis. Although people of any age can be affected by rheumatoid arthritis, it is observed that women are affected three times more than men and the onset is most frequent between the age of 40 and 50 years. Rheumatoid arthritis initiates with the inflammation of the synovial membrane and accumulation of synovial fluid in the joint space. As the disease progresses, it may lead to muscle atrophies, flexion contractures, and ankylosis. The management of rheumatoid arthritis is aimed to reduce pain and inflammation, delay disease progression, preserve joint movement, and prevent deformities. Rumalaya® forte (tablet), from The Himalaya Drug Company, has been found to be safe and effective in the management of all types of arthritis and traumatic inflammatory conditions of the musculoskeletal system. The “Clinical Insight” section of this issue highlights articles on the safety and efficacy of Rumalaya® forte in arthritic conditions. The section also features clinical reports evaluating the safety and efficacy of Septilin® (tablet, syrup) in various infectious conditions and Liv.52® (tablet, syrup) in antitubercular therapy-induced hepatitis. The “Patient Education” section provides information on increasing the child’s immunity.

Happy reading! Dr Pralhad S Patki, MD Editor in chief PROBE • Vol. L • No. 3 • Apr–Jun 2011 iii Editorial The Infection Deep within your heart is where the infection lies. Using your body as a simple disguise. It gets there from sadness and stays there with hate. Once you’ve accepted depression, the infection has sealed your fate. It starts with you and another person and ends when they leave. The pain that you feel is something that you’ d never believe. Sitting in a dark room, letting all of the bitterness just sink in. Trying to escape is pointless, it’s already beneath your skin. The infection has started, it’s eating away at all the happiness you ever had. Slowly but surely you start to go mad. You look in the mirror and you don’ t recognize yourself. How you got to where you are now would make someone deeply question himself. Having the infection is like being lost in your own mind. Turning corners and looking for something that you’ll probably never find. With myself having the infection all I can really do is wait. Until the infection decides my horrible fate. I hope this helps people in the future as I give my recollection. On how you will live when you have the infection. – Anonymous – Editor in chief: Dr Pralhad S Patki Managing Editor: Dr Jayashree B Keshav Editorial Assistants: Pooja Sinha Shruthi VB Riby George Blessin Dan Varghese Layout Artist: Dayananda Rao S Santosh G Printer: M/s Sri Sudhindra Offset Process #97, DT Street, 8th Cross, Malleshwaram, Bangalore - 560 003 Published by: Dr Pralhad S Patki Makali, Bangalore - 562 123 iv E-mail: [email protected] Website: www.himalayahealthcare.com PROBE • Vol. L • No. 3 • Apr–Jun 2011 PROBE is published once in 3 months Subscription rates for four consecutive issues are – Inland: Rs. 20/- inclusive of postage – Abroad: UK£ 5, US$ 12, inclusive of surface mail postage All check payments should cover the banker’s commission Drafts/checks to be sent in favor of: “The Himalaya Drug Company, Makali, Bangalore” Clinical Insight 1 Clinical Efficacy and Safety of Septilin Tablets in Respiratory Tract Infections: A Meta-analysis Kshirsagar M, et al. Department of Pharmacology, BJ Medical College, and Sassoon General Hospital, Pune, India Ind J Clin Pract. 2010;20(8):595-600. Abstract The aim of this study was to perform meta-analysis on the efficacy and short- and long-term safety of Septilin tablet in respiratory tract infections (RTIs), as reported in 38 published studies conducted between 1958 and 2001 in 2765 patients with RTI. Adults received one to two tablets, TID for 7 days to three months. Children were administered one-quarter tablets QID to one tablet TID for 7 days to three months. Duration of the treatment varied from 7 days to 3 months. Improvement in the symptoms, clinical recovery, and immunoglobulin were taken into consideration. Results of the study showed statistically significant improvement in patients with RTI. Of the 1613 patients with upper respiratory tract infection (URTI), 1211 patients responded to the Septilin therapy and among the 838 patients with lower respiratory tract infection (LRTI), 720 patients responded to the therapy. In comparative control trials conducted with Septilin in RTIs, 74.42% of patients treated with Septilin improved as compared to the other treatment (52.86%). But with Septilin treatment, the improvement was better with minimal adverse effects. Immunoglobulin (IgG, IgA, IgM) levels showed significant improvement with Septilin. Adverse effects included gastrointestinal disturbances in 11 cases (0.39%), dry mouth in nine cases (0.32%), and skin rashes in three cases (0.11%). Adverse effects were mild and no patient withdrew from the study on their account. Whereas in the comparative controlled drugs (antibiotics and antiallergics) groups, reported drowsiness and sedation were reported in 21 cases (18%), dry mouth in seven cases (7.78%), and dizziness and incoordination of movements in three cases (3.33%). Therefore, it can be concluded that Septilin tablets are effective and safe in treating RTIs. Key words Septilin, Respiratory tract infections, meta-analysis Intro duc tion The term respiratory tract infection (RTI) describes acute infections involving the nose, paranasal sinuses, pharynx, larynx, trachea, and bronchi. Viruses cause most upper RTIs (URTIs), with rhinovirus, parainfluenza virus, coronavirus, adenovirus, respiratory syncytial virus, coxsackie virus, and influenza virus accounting for most cases.1 In the United States, common cold leads to 75 to 100 million physician visits annually at a conservative cost estimate of US $7.7 billion per year. Americans spend $2.9 billion on over-the-counter drugs and another US $400 million on prescription medicines for symptomatic relief.2,3 More than one-third of patients, who visited a doctor, received an antibiotic prescription, which has implications for antibiotic resistance from overuse of such drugs.3 An estimated 22 to 189 million school days are missed annually due to cold. As a result, parents missed 126 million workdays to stay home to care for their children. When added to the 150 million workdays missed by employees suffering from cold, the total economic impact of cold-related work loss exceeds US $20 billion per year.2,3 This accounts for 40% of time lost from work.4 Most URTIs occur more frequently during the cold winter months. Adults develop an average of two to four colds annually. Antigenic variation of hundreds of respiratory viruses results in repeated circulation in the community. Acute pharyngitis accounts for 1% to 2% of all visits to outpatient and emergency departments, resulting in 7 million annual visits by adults PROBE • Vol. L • No. 3 • Apr–Jun 2011 1 Clinical Insight Septilin in Respiratory Tract Infections alone.1 Acute bacterial sinusitis develops in 0.5% to 2% of cases of viral URTIs.5 Approximately 20 million cases of acute sinusitis occur annually in the United States. About 12 million individuals are diagnosed with acute tracheobronchitis annually, accounting for one-third of patients presenting with acute cough, these infections are the leading cause of death.6 Transmission of organisms causing URTIs occurs by aerosol, droplet or direct hand-to-hand contact with infected secretions, with subsequent passage to the nares or eyes.7 Thus, transmission occurs more commonly in crowded conditions. Direct invasion of the respiratory epithelium results in symptoms corresponding to the area(s) involved. On examination, patients with common colds may have low-grade fever, nasal vocal tone, macerated skin over the nostrils, and inflamed nasal mucosa.8 There is a need for an effective and safe formulation to manage respiratory infections. A number of herbs are claimed to be effective in the management of these frequent infections. Septilin is a multi-herbal formulation claimed for its efficacy due to the synergistic action of the ingredients. It provides immunomodulatory activity that enhances natural immunity. A number of clinical studies have been carried out to evaluate the efficacy and safety of Septilin in various respiratory ailments. Results of each clinical trial showed that Septilin, with its immunomodulatory, antioxidant, antiinflammatory, antiallergic, and antimicrobial actions, was effective in various RTIs, with excellent shortand long-term safety. These studies need to be meta- analyzed to know the clinical status of Septilin in respiratory ailments. Meta-analysis is a two-stage process; first stage is the extraction of data from each study and calculation of the result for each. The second stage involves deciding whether it is appropriate to calculate a pooled average result across studies. This process gives greater weightage to the results from the studies that give more information because these are likely to be closer to the truth.9 Advantages of meta-analysis include deriving and statistical testing of overall factors/effect size parameters in related studies, generalization to the population of studies, ability to control for between study variation, including moderators to explain variation. To cumulate the results of all the studies, a meta-analysis was carried out to analyze the efficacy and short- and long-term safety of Septilin in RTI. Aim of the Study The aim of the study was to perform a meta-analysis on the efficacy and short- and long-term safety of Septilin tablets in RTI. Material and Metho ds Study Design This is a cumulative meta-analysis of 38 published clinical trials of Septilin tablets in RTIs. Out of the 38 trials, 32 were open, one was placebo-controlled, and five were comparative controlled trials. The details of clinical studies evaluated for meta-analysis are mentioned in Table 1.

There were no restrictions regarding sex, age, or duration of the disease. The outcome variables included measurement data on changes in clinical symptoms and signs, laboratory results, and incidence of adverse events during/after the treatment and immunoglobulin levels. efficacy and short- and long-term safety of Septilin in RTIs. Duration of the treatment varied from 7 days to 3 months. Adults received one tablet QID to two tablets TID for 7 days to 3 months. Children recieved one-quarter tablet QID to 1 tablet TID for 7 days to 3 months. Improvement in symptoms, clinical recovery, and immunoglobulin levels were taken into consideration. Incidence of adverse events during the study period and compliance to the drug treatment were also evaluated. Exclusion Criteria Primary and Secondary Outcome Measure Phase I studies were excluded from the meta-analysis. Study Procedures A meta-analysis of 38 clinical studies conducted between 1958 and 2001 in 2765 patients with RTI (1613 were with URTI and 838 were with lower RTI) at various reputed hospitals all over India was performed to evaluate the Primary predefined outcomes were clinical recovery from RTIs. Secondary end points were safety and compliance to Septilin tablets. Adverse Effects All adverse events, either reported or observed by patients, were recorded with information about severity, PROBE • Vol. L • No. 3 • Apr–Jun 2011 3 Clinical Insight Septilin in Respiratory Tract Infections duration, and action taken regarding the study drug. Relation of adverse events to study medication was predefined as ‘Unrelated’ (a reaction that does not follow a reasonable temporal sequence from the administration of the drug), ‘Possible’ (follows a known response pattern to the suspected drug, but could have been produced by the patient’s clinical state or other modes of therapy administered to the patient), ‘Probable’ (follows a known response pattern to the suspected drug that could not be reasonably explained by the known characteristics of the patient’s clinical state), and ‘Certain’ (the adverse events must have definitive relationship to the study drug, which cannot be explained by concurrent disease or any other agent). Statistical Analysis Statistical analysis was done according to the intentionto-treat principles. Changes in various parameters from baseline values and values at the end of the study were pooled and analyzed cumulatively using Chi square test or paired t test. Values are expressed as mean ± SD or as incidences of patients with or without symptoms. The minimum level of significance was fixed at 95% confidence limit and a two-sided P≤.05 was considered significant. Statistical analysis was performed using GraphPad Prism Version 4.03 for windows, GraphPad Software, San Diego, California, United States (www.graphpad.com). Re sults The break-ups for upper and lower RTIs are given in Table 2. Statistically significant improvement was seen in trials conducted in patients with RTI. Of the 1613 patients with URTI, 1211 patients responded to the treatment, with a statistical significance of P<.0001 and percent protection of 75.08% and among the 838 patients with lower RTI (LRTI), 720 patients responded to the treatment, with a statistical significance of P<.0001 and percent protection of 85.92% (Table 3). Among patients with URTI, in 565 patients with tonsillitis, 460 patients responded with 81.42% protection; in 599 patients with pharyngitis, 411 responded showing 68.61% protection; in 25 patients with laryngitis 24 showed 96% protection; and in patients with sinusitis and Table 3.

Clinical Insight Septilin in Respiratory Tract Infections rhinitis, 76.89% and 91.01% protection was observed, respectively (Table 3). Similarly in LRTI out of 683 patients with bronchitis, 589 responded with 86.24% and persistent cough due to varied etiology there was 84.52% relief (Table 3). In the comparative control trial, 74.42% of patients treated with Septilin improved as compared to the control group (52.86%) treated with antiallergics and antibiotics. The statistical significance was P<.0001 (Table 4) in both Septilin and control groups, but improvement was found to be better with Septilin treatment. The comparative drugs were antiallergics (chlorpheniramine maleate) and antibiotics (cotrimoxazole and penicillins). patients (0.11%) treated with septilin. In patients treated with comparative controlled drugs (antibiotics and antiallergics), were observed in adverse effects such as drowsiness and sedation in 21 cases (18%), dry mouth in seven patients (7.78%), and dizziness and incoordination of movements in three cases (3.33%). All adverse effects were mild in nature and did not necessitate withdrawal of study medication (Table 6). Majority of the adverse effects were seen in patients treated with comparative controlled drugs (140) such as antibiotics and antiallergics (28%) as compared to <1% in Septilin-treated patients. The immunoglobulin levels showed significant improvement, IgG from 1456.00 ± 342.80 mg/dL at baseline to 1715.00 ± 287.10 mg/dL after the treatment (P<.009), IgA from 200.80 ± 46.73 mg/dL before treatment to 241.40 ± 43.26 mg/dL after treatment (P<.01), and IgM levels from 167.80 ± 68.38 mg/dL before treatment to 195.70 ± 63.21 mg/dL after treatment (P<.01), in two open-label clinical trials (Table 5). These observations support the immunomodulatory effect of Septilin. Out of the 2765 patients with RTI, gastrointestinal disturbances were observed in 11 cases (0.39%), dry mouth in nine cases (0.32%) and skin rashes in three The number of papers published on meta-analysis in medical research has increased sharply in the past decade; however, the merits and perils of the meta-analysis continue to be debated in the medical community.48,49 A useful definition of meta-analysis was given by Huque as: A statistical analysis that combines or integrates the results of several independent clinical trials considered by the analyst to be combinable.50 A single study often cannot detect or exclude with certainty clinically relevant differences in the effects of two treatments. Cumulative meta-analysis is defined as the repeated performance of meta-analysis whenever a new trial becomes available Discussion Table 5.

Such cumulative meta-analysis can retrospectively identify the point in time when a treatment effect first reached conventional levels of significance.51 Meta-analysis thus not only consists of a combination of data but also includes the epidemiological exploration and evaluation of results (epidemiology of results).52 Therefore, new hypotheses that were not posed in single studies can be tested in meta-analyses.53 The number of patients included in clinical trials is often inadequate, as in some cases the required sample size may be difficult to achieve.54 Meta-analysis may, nevertheless, lead to the identification of the most promising or urgent research question and may permit a more accurate calculation of the sample sizes needed in future studies.55 Goals of the meta-analysis are to enable the overall significance of an effect to be evaluated, based on the multiple studies available, to estimate an overall effect size by combining the individual estimates in multiple studies.56 In the present meta-analysis, clinical trials and their details were tabulated and analyzed statistically. The outcome of this analysis showed marked improvement with Septilin in patients with RTIs. Septilin has immunomodulatory, antioxidant, antiinflammatory, antiallergic, and antimicrobial actions. It has an excellent short- and long-term safety. Septilin is a multiherbal preparation and the effect of the formulation is due to the synergistic action of the ingredients. Tinospora cordifolia has potent immunomodulatory and immunostimulatory actions, which increase the levels of antibodies and activate macrophages.57,58 Emblica officinalis enhances cell survival and increases phagocytosis and gamma-interferon production.59 Glycyrrhizin from Glycyrrhiza glabra potentiates the reticuloendothelial system,60 enhances 61 immunostimulation, and acts on macrophage function in vitro, leading to stimulation of macrophages de novo,62 b-glycyrrhetinic acid from G glabra is a potent inhibitor of the classical complement pathway.63 Balsamodendron mukul,64‑66 Rubia cordifolia,67 E officinalis,68 G glabra,69 and Moringa pterygosperma70 have potent antioxidant actions. B mukul has strong anti-inflammatory potential.71 G glabra72 and M pterygosperma73 have also been reported for its anti-inflammatory properties. T cordifolia improves the phagocytic and intracellular bactericidal capacities of neutrophils.74 Glycyrrhizin from G glabra has potent antiviral activity.75 E officinalis has antibacterial properties, especially against Escherichia coli, Klebsiella pneumoniae, Klebsiella ozaenae, Proteus 6 PROBE • Vol. L • No. 3 • Apr–Jun 2011 Septilin in Respiratory Tract Infections mirabilis, Pseudomonas aeruginosa, Salmonella typhi, Salmonella paratyphi A and B, and Serratia marcescens.76 has antibacterial properties.77 M pterygosperma possesses antibacterial and antiviral properties and inhibits the growth of gram-positive and gram-negative bacteria such as E coli, S typhi, and S paratyphi.78 T cordifolia79 and E officinalis80 have antipyretic properties. B mukul is beneficial in RTIs, including chronic tonsillitis, pharyngitis, chronic bronchitis, nasal catarrh, and laryngitis.81 G glabra is an expectorant and hence is beneficial in asthma, acute or chronic bronchitis, and chronic cough.82-84 Conclusion The outcome of this meta-analysis, which included 38 clinical studies carried out between 1958 and 2001, in 2765 patients with RTI indicated significant clinical efficacy and safety of Septilin tablets. The cumulative data analysis revealed significant clinical improvement with adequate symptomatic relief in Septilin-treated patients. Adverse events were negligible (<1%) in Septilin-treated patients and did not necessitate withdrawal of the drug. The overall drug compliance was very good. Therefore, it may be concluded that Septilin tablets are clinically effective and safe in patients with RTIs. Septilin, a multiingredient formula, has immunomodulatory activity and enhances natural immunity. It is also a safe and effective adjuvant to antimicrobials in the management of recurrent infections. When coprescribed with antibiotics, Septilin ensures faster recovery and reduces the duration and cost of therapy, besides preventing reinfections. Reference s 1. Cooper RJ, et al.

PROBE • Vol. L • No. 3 • Apr–Jun 2011 7 Clinical Insight Rumalaya forte in Osteoarthritis Evaluation of the Efficacy and Safety of JT-2000* in Osteoarthritis: A Comparative Clinical Trial Mathur HH, et al. Department of Orthopedics, Medical College & S. S. G. Hospital, Vadodara, India Med Update. 2004;11(9):31-37. Abstract Osteoarthritis is a major cause of morbidity and impaired quality of life among the elderly. The use of nonsteroidal anti-inflammatory drugs (NSAIDs) is associated with short-term and long-term adverse effects. The present study was conducted to evaluate clinical efficacy (in comparison to Ibuprofen) and long-term safety of JT-2000 in patients with osteoarthritis. This study was an open placebo controlled clinical trial undertaken in 100 patients of osteoarthritis of either sex, in the age group of 50 to 65 years. Ambulatory patients with primary osteoarthritis of the knee and clinical symptoms for 6 months, who had radiological evidence of osteoarthritis, were included in the study. Patients with established hypertension or renal, hepatic and cardiac failure, on steroids and with biochemical and clinical evidence of rheumatoid arthritis (RA) and gout, were excluded. Recording signs and symptoms with systemic and joint examination, biochemical investigations, liver function test, renal function tests, rheumatoid arthritis factors, IgA, and IgM levels with radiography of the joints were done at baseline, 3 months, and 6 months. Subjective and objective evaluations were carried out every 4 weeks with a final follow-up at the end of 6 months. The scoring system was used to evaluate subjective and objective scores. Efficacy was assessed by the decrease in total signs and symptom score at 6 months; safety was assessed by incidence of adverse effects and laboratory evaluation. The minimum level of significance was fixed at 95% confidence interval and a 2-sided P value of <.05 was considered significant. Objective improvement was comparable in both groups with a significant reduction in symptom scores after treatment in both groups. No significant alteration was seen in most of the hematological parameters in both groups. A significant increase in total proteins, alkaline *JT-2000 is marketed as Rumalaya forte 8 PROBE • Vol. L • No. 3 • Apr–Jun 2011 phosphatase, and blood urea nitrogen was seen in the Ibuprofen group. There was a significant decrease in the SGOT and SGPT levels in the JT-2000 group. Creatinine levels decreased significantly in the JT-2000 group, and increased significantly in the Ibuprofen group. Radiological examination done at 3 and 6 months did not show any deterioration when compared to pretherapy images. No untoward side effects were reported during the trial in all the 50 patients. In the Ibuprofen group, 40% patients had gastrointestinal, neurological, and dermatological adverse effects. In the JT-2000 group, there was a significant decrease of SGOT and SGPT that was indicative of hepatoprotective effect of JT-2000, corroborated by significant decrease in creatinine. Adverse drug reactions were limiting factors in the long-term safety of Ibuprofen. This study indicated that JT-2000 was an equally effective, but safe alternative for long-term use in the management of mild to moderate osteoarthritis. Key Words Osteoarthritis, nonsteroidal anti-inflammatory drugs, rheumatoid arthritis factors, Rumalaya forte Intro duc tion Osteoarthritis (OA) is a slow progressing degenerative disease of the joints (involving both weight-bearing and non weight-bearing joints). It is one of the most common forms of arthritis encountered in clinical practice, which affects an increasing aging population. Osteoarthritis is a major cause of morbidity, disability, and impaired quality of life, especially among the elderly. The etiology of osteoarthritis is multifactorial, and is influenced by age, sex, genetic, and biomechanical factors. The association between repetitive joint trauma (sports, work-related, or accidental) and osteoarthritis is well documented. Clinical Insight Rumalaya forte in Osteoarthritis The cardinal feature of osteoarthritis is the osteoarthritic lesion in the cartilage that disrupts the chondrocytematrix association and alters metabolic responses in the chondrocytes to contribute to the functional breakdown of the joint’s cartilage, leading to constant friction between the bones. Clinically, OA manifests as pain, discomfort, and swelling and stiffness in the joints. They may be associated with loss of flexibility of the joint; intraosseous increase in vascular pressure; periosteal proliferation; subchondral fracture; and evidence of sclerosis, ligament laxity, muscle spasm, and synovitis. Materials and Metho ds The diagnosis of osteoarthritis is arrived through a detailed clinical history, physical and radiological examination of the joint, and if required, aspiration of synovial fluid to confirm diagnosis. About 60% of patients have suggestive radiological signs, while only a third of them may have actual symptoms. Study population Treatment includes symptomatic therapy for pain, stiffness, and swelling. The therapy is directed to modify the joint structure leading to retardation and reversal or prevention of the disease process. The drug treatment options available for osteoarthritis include topical and systemic analgesics, anti-inflammatory agents (mainly NSAIDs), and intra-articular injections of corticosteroids or hyaluronic acid. Cyclo-oxygenase enzyme inhibitors (nonselective, preferably selective, and specifically selective) are widely used in the management of OA, but the present evidence does not suggest their efficacy in preventing disease progression. Furthermore, the usage of NSAIDs is linked with numerous short- and long-term adverse effects and these drugs are associated with an increased morbidity in older patients. An intra-articular injection of corticosteroid or hyaluronic acid offers analgesia for 4 to 6 months but is associated with an increased risk of intraarticular infections. JT-2000 is a polyherbal formulation containing extracts of Boswellia serrata, Alpinia galanga, Commiphora wightii, Glycyrrhiza glabra, Tinospora cordifolia, and Tribulus terrestris, which have clinically been proven to possess effective anti-inflammatory and analgesic activities. The present study was conducted to evaluate clinical efficacy, in comparison with Ibuprofen (a commonly prescribed NSAID), and long-term safety of JT-2000 in patients with osteoarthritis in one or both knee joints. Aim of the study To evaluate the clinical efficacy and long-term safety of JT-2000, in comparison with Ibuprofen, in patients with osteoarthritis of one or both knee joints. Study design The study was an open clinical trial approved by the Institutional Ethics Review Committee. A written informed consent was obtained from all the patients. One hundred patients of either sex, in the age group of 50 to 65 years, with osteoarthritis of one or both knee joints who attended the Department of Orthopedics, SSG Hospital, Baroda, between April 1, 2002 and August 31, 2002, were enrolled in the study. They were divided into two groups. The study medication group received 2 capsules of JT-2000, twice daily for a period of 6 months and the placebo medication group received one tablet (400mg) thrice daily for a period of 6 months. The two groups were similar with regard to the demographic data, baseline parameters, and pain score. Inclusion criteria Ambulatory patients of both sexes in the age group of 50 to 65 years, with primary OA of the knee (tibiofemoral joint) were included in the study. All patients had clinical symptoms of OA for at least 6 months prior to the study and were suffering from moderate to severe knee pain (with or without morning stiffness of <30 minutes duration). These patients had radiological evidence of osteophytes with findings like marginal lipping, narrowing of joint space, and sharpened articular margin or sclerosis (damaged, thickened, eburnated subchondral bone, or bone cysts). Exclusion criteria Patients with established hypertension, renal, hepatic or cardiac failure, on long-term steroid treatment, or with biochemical and clinical evidence of rheumatoid arthritis or gout were excluded from the study. Methodology Selected patients underwent a complete physical examination before the trial. All signs and symptoms with regard to severity and duration were recorded before PROBE • Vol. L • No. 3 • Apr–Jun 2011 9 Clinical Insight commencing treatment. A complete systemic and joint examination was also performed. Biochemical investigations and radiography of the joints were noted at 3 months and after 6 months. Blood chemistry investigations included complete hemogram (ESR, WBC, erythrocytes, and platelet count), liver function tests (including SGOT, SGPT, bilirubin, serum proteins, alkaline phosphatase, prothrombin time), renal function tests (including uric acid, urea, and creatinine), and assessing RA factor and immunoglobulins (IgA and IgM). Radiological examination of the affected joints was carried out for osteophytes, spiking of tibial spine, subchondral sclerosis, and cysts, loose bodies, and deformities (varus or valgus). Follow-up and assessment Subjective and objective evaluation was carried out every 4 weeks for 24 weeks with a final follow-up at the end of 6 months. The scoring system was designed to evaluate subjective and objective scores, which were compared before and after treatment. A complete clinical, biochemical, and radiographical evaluation was carried out at the end of the three and six months. Primary outcome measures Efficacy was assessed by a decrease in total signs and symptom score at the end of 6 months. The total symptom score was based on the number of joints involved, degree of pain, joint swelling, stiffness, and activity level. The total sign score was based on joint effusion, and tenderness, crepitus, range of movements, synovial hypertrophy, muscle wasting, and joint deformity (Table 1). Safety was assessed by incidence of adverse effects and laboratory evaluation of complete hemogram with clinical biochemistry (including liver and kidney function tests). Statistical analysis An analysis was done according to intention-to-treat principles. Comparison of the two groups for baseline comparability of different parameters by unpaired t test was done. Changes in various parameters from baseline values after the three and six months were evaluated by paired t test. The reduction in pain and swelling scores were evaluated to differentiate between the two treatment groups by unpaired t test. The minimum level of significance was fixed at 95% confidence limit and a 2-sided P value of <.05 was considered significant. 10 P R O B E • V o l . L • N o . 3 • A p r – J u n 2 0 1 1 Rumalaya forte in Osteoarthritis Re sults In JT-2000 group 76% of the patients were in the age group of 50 to 55 years. The male to female ratio was equal in the JT-2000 group, while in the Ibuprofen group, there was a male preponderance (1.77: 1); this difference was due to randomization (Table 2 and Figure 1). A majority of patients in both groups had bilateral knee involvement but only a few (8% in JT‑2000 and 14% in Ibuprofen group) had unilateral signs and symptoms. A majority of patients in both groups had a pretherapy total symptom score of 7 points (72% in JT-2000 and 84% in the Ibuprofen group). Before initiation of the therapy, a majority of patients in both groups had pain during less than routine work, swelling of joint/s or stiff joints, were comfortable only with straight walking and found difficulty or inability in cross-leg sitting, squatting, and stair climbing activities. In more than 80% of cases in both groups (86% in JT-2000 and 84% in Ibuprofen), the posttherapy total symptom score reduced (Table 3 and Figure 2). All these patients, at the end of the therapy, experienced pain only during more than routine work, there was a reduction in swelling and joint stiffness and they were comfortable with straight walking, cross-leg sitting, squatting, and stair climbing activities. The relief in symptoms was comparable in both groups and the onset of appreciable symptomatic improvement was marginally faster with Ibuprofen (within 5 days) as compared to JT-2000 (10-12 days). The objective improvement was comparable in both groups and there was statistically significant reduction in the symptom scores after treatment in both groups. By the end of 6 months, all the patients had significant pain relief, loss of joint line tenderness, decrease in joint stiffness, increase in joint mobility, and improved activity level (Table 4 and Figure 3). No significant alterations were seen in most hematological parameters in both groups, except a significant decrease in eosinophils and ESR and a significant increase in neutrophils in the JT-2000 group (Table 5). In biochemical parameters, total proteins, ALP, and BUN showed significant increase in the Ibuprofen group, while SGOT, SGPT showed significant decrease in JT-2000 group. Creatinine levels were found to be significantly decreased in the JT-2000 group, and significantly increased in the Ibuprofen group (Table 6). Radiological examination done at 3 and 6 months did not show any deterioration as compared to pretherapy images. Clinical Insight Rumalaya forte in Osteoarthritis Table 1.

No untoward side effects were reported during the trial in all the 50 patients. In the Ibuprofen group, 20 patients reported adverse drug reactions (ADRs) and 16 patients had nausea, retrosternal burning, abdominal discomfort, flatulence, and dyspepsia at some stage of therapy. These patients were prescribed H2 receptor antagonist or antacid or both as required (Figure 4). Three patients developed headache and dizziness, which eventually subsided on its own and one patient presented with skin rashes and itching and was prescribed oral antiallergics for 2 weeks. Discussion Osteoarthritis is a chronic, progressive disability affecting the elderly. The long-term use of NSAIDs in its management has been shown to be associated with serious adverse effects.1-5 Herbal formulations have been proven to be effective and safe alternatives to NSAIDs. The primary constituent of JT-2000 is B serrata, which has been long used in the management of osteoarthritic conditions.6 Clinical studies using herbal formulas with Boswellia have yielded good results in both osteoarthritis and rheumatoid arthritis.7,8 In B serrata, the active principal compound is boswellic acid, which has demonstrated antiarthritic effects in experimental studies and several suggested mechanisms of action include inhibition of proinflammatory mediators (5-lipooxygenase including 5-hydroxyeicosa tetranoic acid and leukotrienes), prevention of decreased glycosaminoglycan synthesis (which is known to accelerate articular damage), and improved blood supply to joint tissues.9-12 Rumalaya forte in Osteoarthritis increase in the total proteins, alkaline phosphatase, and blood urea nitrogen which may not be of any clinical significance. A significant decrease of SGOT and SGPT in the JT‑2000 group was indicative for hepatoprotective effect of JT-2000, which is also corroborated by significant decrease in creatinine levels in the JT-2000 group, while in contrast the Ibuprofen group showed a significant increase. Radiological follow-up also confirmed inflammatory control by absence of any signs of deterioration as compared to pretherapy images in both groups. The major clinically significant difference in both the groups was noted in ADRs, which was a limiting factor in the long-term safety of Ibuprofen. In contrast, JT-2000 appeared much safer for long-term usage. Conclusion Arthritis and inflammatory disorders are the common causes of morbidity in the aging population worldwide. Apart from pain, loss of joint function, and restricted mobility, there is also considerable compromise in quality of life. Current nonsurgical drug therapies (especially NSAIDs) have their own limitations regarding their host of ADRs and are therefore of questionable advocacy for long-term use. Furthermore, the chronic nature of osteoarthritic process itself demands a long-term drug therapy for years, especially in cases where patients are not willing to undergo any surgical intervention. This study indicated that JT-2000 is an equally effective and safer alternative for long-term use in management of mild to moderate osteoarthritis than NSAIDs. Reference s 1. Schidodt FV, et al.

Clinical Insight Liv.52 in the Prevention of Hepatotoxicity in Patients receiving Antitubercular Drugs: A Meta-analysis of Eight Controlled Clinical Trials Dange SV Prof. of Medicine, D.Y. Patil Medical College, Pune, Maharashtra, India IJCP. 2010;21(2):81-86. Abstract The aim of this study was to conduct a meta-analysis on the efficacy and short- and long-term safety of Liv.52 as a hepatoprotective in tuberculosis patients receiving antitubercular drugs, as published in eight controlled clinical trials. Meta-analysis of eight clinical studies conducted between 1970 and 1992 in 689 tubercular patients receiving antitubercular treatment along with Liv.52 or placebo was taken up for this study. Duration of the treatment varied from 4 weeks to 1 year. Children below the age of 2 years received 10 to 20 drops of Liv.52 three to four times daily. Children in the age group of 2 to 5 years received 20 drops of Liv.52 three times daily. Adults received 1 to 2 teaspoonsful of Liv.52 syrup three times daily or 1 to 2 tablets of Liv.52 two to three times daily. Improvement in various parameters of hepatotoxicity, such as hepatomegaly, anorexia, weight gain, general well-being, and liver function test (ALT) and ultrasonographic findings of the hepatobiliary system were taken into consideration. Changes in various parameters from baseline values and values at the end of the study were pooled and analyzed cumulatively using Fischer’s exact test or unpaired Students t test. Statistical analysis was performed using GraphPad Prism software (Version 4.03). Results of the meta-analysis showed a statistically significant improvement in the hepatotoxicity in patients receiving antitubercular drugs and Liv.52. Significant improvements were observed in associated symptoms such as anorexia, weight gain, hepatomegaly, and general well-being. The protective effect of Liv.52 against hepatotoxic reaction caused by antitubercular treatment (ATT) was further substantiated by a significant reduction in alanine aminotransferase (ALT) values and alleviation of gastrointestinal (GI) symptoms due to hepatitis. No adverse effects were reported or observed due to Liv.52 during the study period and the compliance to the drug therapy was good. Therefore, from the above findings it can be concluded that Liv.52 acts as a hepatoprotective in the hepatotoxicity of tuberculosis patients receiving antitubercular treatment. Key Words Meta-analysis, Liv.52, hepatotoxicity, antitubercular drugs Intro duc tion Tuberculosis is a common problem worldwide, especially after the recent increase in the incidence of acquired immunodeficiency syndrome (AIDS) and multiple drug resistant tuberculosis (MDR-TB) due to inefficient management.1 Every year, an estimated eight million new cases and two million deaths occur due to TB worldwide.2 At present, most commonly used anti-TB drugs are more or less hepatotoxic, especially when several anti-TB drugs are used in combination. Liver dysfunction caused by anti-TB drugs often results in interruption of anti-TB therapy and acute hepatic failure, which is life threatening.3,4 Druginduced hepatotoxicity is a potentially serious adverse effect of antituberculosis treatment regimens containing isoniazid, rifampicin, and pyrazinamide.5 The underlying mechanism of antitubercular treatment (ATT)-induced hepatotoxicity and the factors predisposing to its development are not clearly understood. Age and sex of the patients, chronic alcoholism and chronic liver disease, hepatitis B virus carrier status, and acetylator and nutritional status have all been incriminated as possible predisposing factors in earlier studies. As enzymes for drug metabolism in hepatocyte microsomes may have congenital defect, malformation, and low activity or may be inhibited by drugs, drugs or drug metabolites are very toxic to hepatocytes. The other reason is hypersensitivity to drugs. The drugs as a hapten cause allergic reaction by immune mechanism, leading to an increase in alanine aminotransferase (ALT) alone in clinical situation.6 PROBE • Vol. L • No. 3 • Apr–Jun 2011 15 Clinical Insight Commonly used antitubercular drugs, such as isoniazid, rifampicin, and pyrazinamide, are hepatotoxic.6 Isoniazid causes hepatic damage by either toxicity or hypersensitivity induced by its metabolite— acetylhydrazine. Rifampicin may accelerate the metabolism of isoniazid as a strong enzyme inducer, resulting in an increase in acetylhydrazine. This combines with biomacromolecules in liver, leading to hepatocellular damage (usually seen in aged patients with excessive drinking), malnutrition, or liver ailment. Pyrazinamide hepatotoxicity is dose dependent and the general dose rarely causes hepatic damage. Isoniazid and rifampicin are the first-line anti-TB medicines because of their strong bactericidal effects.7,8 The clinical presentation of ATT-associated hepatitis is similar to that of acute viral hepatitis. ATT can cause varied degree of hepatotoxicity from a transitory asymptomatic rise in transaminases to acute liver failure. The frequency of hepatotoxicity in different countries varies widely from 2% to 39%.9 The occurrence of drug-induced hepatotoxicity is unpredictable, but it is observed that certain patients are at a relatively higher risk as compared to others. Liv.52, a polyherbal formulation, is used extensively in the management of various hepatic disorders over the past 55 years. The principal herbs used in the preparation of Liv.52 include Capparis spinosa, Cichorium intybus, Solanum nigrum, Terminalia arjuna, Cassia occidentalis, Achillea millefolium, and Tamarix gallica. Liv.52 was evaluated for its efficacy in the prevention of hepatotoxicity induced by antitubercular drugs in 689 tuberculosis patients receiving ATT, as reported in eight controlled clinical trials conducted between 1970 and 1992. Results of each clinical trial with Liv.52 showed significant hepatoprotective effect, both clinically and as determined through liver function test (ALT). The study also showed good short- and long-term safety. These studies need to be meta-analyzed to further substantiate the clinical efficacy of Liv.52 as a hepatoprotective in tuberculosis patients receiving antitubercular drugs. A meta-analysis is a two-stage process; the first stage is the extraction of data from each study and the calculation of result for each study. The second stage involves deciding whether it is appropriate to calculate a pooled average result across studies. This process gives greater weightage to the results from the studies that give more information.10 Advantages of meta-analysis include deriving and generalization of the population studies, ability to control 16 P R O B E • V o l .

To cumulate the result of all the studies, a meta-analysis was done to analyze the efficacy and short- and long-term safety of Liv.52 as a hepatoprotective in tuberculosis patients receiving antitubercular drugs. Aim of the study The aim of the study was to conduct a meta-analysis on the efficacy and short- and long-term safety of Liv.52 in patients receiving antitubercular drugs, as reported in eight controlled clinical trials. Materials and Metho ds Study design This is a cumulative meta-analysis of eight published controlled clinical trials of Liv.52 in the prevention of hepatotoxicity in patients receiving antitubercular drugs. Of these eight controlled trials, one was a double-blind placebo-controlled study and the remaining seven were controlled studies. Inclusion criteria All published studies, which evaluated the efficacy and safety of Liv.52 in hepatotoxicity due to antitubercular treatment, were included in the meta-analysis irrespective of the study design. The meta-analysis included eight controlled clinical trials and there were no restrictions regarding sex, age, or duration of the disease. The outcome variables included measurement of data on changes in clinical symptoms and signs of hepatotoxicity, laboratory results, and incidence of adverse events during/ after the treatment. Exclusion criteria Phase I studies conducted with Liv.52 and uncontrolled studies were excluded from the analysis. Study procedures Eight controlled clinical studies conducted between 1970 and 1992 in 689 tubercular patients receiving ATT and presenting with hepatotoxicity were subjected to metaanalysis. Duration of the treatment varied from 4 weeks to 1 year. Children below the age of 2 years received 10 to 20 drops of Liv.52 three to four times daily. Children in the age group of 2 to 5 years received 20 drops of Liv.52 three times daily. Adults received 1 to 2 teaspoonsful of Liv.52 syrup three times daily or 1 to 2 tablets of Liv.52 two to Clinical Insight Liv.52 in ATT-induced toxicity three times daily. Improvement in the various parameters of hepatotoxicity, such as hepatomegaly, anorexia, weight gain, and general well-being and ultrasonographic findings of the hepatobiliary system were taken into consideration. Changes in various parameters from baseline and at the end of the study were pooled and analyzed. The incidence and type of adverse events reported by various studies were also tabulated separately. All adverse events, either reported or observed by patients or investigators, were recorded with information about severity, duration, and action taken regarding the study drug. Relation of adverse events to study medication was predefined as “Unrelated” (a reaction that does not follow a reasonable temporal sequence from the administration of the drug), “Possible” (follows a known response pattern to the suspected drug, but could have been produced by the patient’s clinical state or other modes of therapy administered to the patient), “Probable” (follows a known response pattern to the suspected drug that could not be reasonably explained by the known characteristics of the patient’s clinical state), and “Certain” (the adverse events must have definitive relationship to the study drug, which cannot be explained by concurrent disease or any other agent). 302 served as controls. The age varied from 2 months to 60 years and the duration of the treatment varied from 4 weeks to 1 year (Table 1). Details of the eight controlled clinical trials are enumerated in Table 2. Among the 220 patients presenting with anorexia, who received Liv.52 in addition to antitubercular treatment, only 16 patients were presenting with anorexia at the end of the treatment, showing a significant improvement (P<.0001). Whereas in 163 patients (controls) received antitubercular treatment, anorexia was persistent in 160 patients (Table 3). Among the 186 patients presenting with weight loss, who received Liv.52 in addition to antitubercular treatment, Table 1.

It appears that the process of enzymatic induction witnessed with rifampicin metabolism is not influenced by the addition of Liv.52 (Table 9). Clinical Insight Liv.52 in ATT-induced toxicity There were no adverse effects observed or reported during the clinical trials in patients who received Liv.52 Table 9.

There were no drop outs or withdrawal from the study. Discussion A useful definition of meta-analysis was given by Huque as “A statistical analysis that combines or integrates the results of several independent clinical trials considered by the analyst to be combinable.”19 A single study often cannot detect or exclude with certainty clinically relevant differences in the effects of two treatments. Cumulative meta-analysis is defined as the repeated performance of meta-analysis whenever a new trial becomes available for inclusion. Such cumulative meta-analysis can retrospectively identify the point in time when a treatment effect first reaches conventional levels of significance.20 Meta-analysis thus not only consists of the combination of data but also includes the epidemiological exploration and evaluation of results (epidemiology of results).21 Therefore, new hypotheses that were not posed in single studies can be tested in meta-analyses.22 The number of patients included in clinical trials is often inadequate, as in some cases the required sample size may be difficult to achieve.23 Meta-analysis may, nevertheless, lead to the identification of the most promising or urgent research question and can permit a more accurate calculation of the sample sizes needed in future studies.24 Goals of metaanalysis are to enable the overall significance of an effect to be evaluated, based on the multiple studies available, and to estimate an overall effect size by combining the individual estimates in multiple studies.25 In the present meta-analysis, clinical trials and their details were tabulated and analyzed statistically. The clinical trial included in the meta-analysis consisted of patients suffering from various types of tuberculosis such as pulmonary, abdominal, childhood tuberculosis, tuberculous meningitis, military tuberculosis, and tubercular cervical lymphadenitis. The outcome of this analysis showed marked improvement with Liv.52 as a hepatoprotective in patients treated with antitubercular drugs, as indicated by relief in clinical symptoms, maintenance of ALT levels, and regression of liver size (as observed clinically and ultrasonographically). The efficacy of Liv.52 is attributed to the potent hepatoprotective herbs present in the formulation, which is described below in detail. C spinosa was found to possess potent hepatoprotective activity against CCl4 -, paracetamol (in vivo)-, thioacetamide-, and galactosamine (in vitro)‑induced hepatotoxicity.26 Strong anti-inflammatory activity of C spinosa was demonstrated, which was comparable to oxyphenbutazone.27 C spinosa was found to possess significant antioxidant, antimicrobial, and antifungal activities.28-30 C intybus revealed hepatoprotective effect against CCl4 -induced hepatotoxicity as indicated by significant prevention of the elevation of malondialdehyde formation (plasma and hepatic) and enzyme levels (aspartate aminotransferase [AST] and ALT) along with restoration of the histoarchitecture.31,32 C intybus showed significant increase in the number of circulating leukocytes, the weights of concerned organs (liver, spleen, and thymus), number of splenic plaque-forming cells, hemagglutination titers, and the secondary IgG antibody response against ethanol-induced toxicity. There were also significant increases in delayed-type hypersensitivity reaction, phagocytic activity, natural killer cell activity, cell proliferation, and interferon gamma-secretion.33 Reports suggest that the observed hepatoprotective effect of C intybus might be due to its ability to suppress the oxidative degradation of DNA in the tissue debris34 and potent antioxidant activity (radical scavenging effects, inhibition of hydrogen peroxide, and iron chelation).35 It also showed marked cytoprotective activity, which was established against ethanol-induced liver damage. The cytoprotective activity was further supported by restoration of histoarchitecture of the liver.36 S nigrum investigated against CCl4 -induced hepatic damage showed remarkable hepatoprotective activity as confirmed by evaluated biochemical parameters including AST, ALT, ALP, and total bilirubin levels.37 It also demonstrated to protect DNA against oxidative PROBE • Vol. L • No. 3 • Apr–Jun 2011 19 Clinical Insight damage and suppress the oxidative degradation of DNA in the tissue debris.34 S nigrum was found to possess a potent antioxidant activity, which was demonstrated by scavenging of hydroxyl radicals and DPPH radicals.38,39 The potent antioxidant activity of T arjuna might be due to its effects on lipid peroxidation.40 T arjuna was found to inhibit nitric oxide (NO) production41 and decrease inducible nitric oxide synthase (iNOS) levels in lipopolysaccharide-stimulated peritoneal macrophages.42 Potent antiviral (by virtue of inhibition of viral attachment and penetration) and antibacterial activities of T arjuna were reported.43,44 Liv.52 in ATT-induced toxicity Therefore, it can be concluded from the meta-analysis that Liv.52 treatment prevented hepatotoxic reactions in patients received antitubercular treatment. These findings clearly suggest the beneficial role of Liv.52 in the management of drug-induced (ATT) hepatotoxicity. Reference s 1. Global tuberculosis control.

Significant hepatoprotective effects of C occidentalis in chemically induced liver damage were noted.45 C occidentalis modulates hepatic enzymes and provides hepatoprotection against cyclophosphamide-induced immunosuppression.46 Antimicrobial properties of C occidentalis were comparable with standard reference antibiotics.47 Strong antibacterial activity of C occidentalis against Salmonella typhi was demonstrated.48 4.

Clinically beneficial effects of A millefolium in the treatment of chronic hepatitis was demonstrated.49 Similar clinical improvements in chronic hepatocholecystitis and angiocholitis with A millefolium were established.50 Antioxidant and antimicrobial activities of A millefolium was also reported.51 12. Indira Bai K, et al. Antiseptic. 1970;6(7):615-617. Therefore, as discussed above, these synergistic actions (hepatoprotective, antimicrobial, antioxidant, and antiinflammatory) exhibited by the ingredients of Liv.52 might provide the protective action against hepatotoxic reaction in patients receiving antitubercular treatment. 18. Purohit SD, et al. Probe. 1988;XXVII(4):261-265. Conclusion 23. Collins R, et al. BMJ. 1992;304:1689. This meta-analysis of eight controlled clinical trials revealed a highly significant hepatoprotective activity of Liv.52 in tuberculosis patients receiving antitubercular treatment, as evidenced from improvement in clinical parameters and liver function test (ALT). These remarkable results might be due to the synergistic activities of the potent hepatoprotective individual herbs of Liv.52. It was also observed that Liv.52 offered hepatoprotective activity without interfering the pharmacokinetics of antitubercular drugs such as rifampicin, which is the most common first-line drug in ATT. There were no clinically significant adverse reactions due to Liv.52 in any of these studies. In all these eight studies, overall compliance to Liv.52 treatment among patients who received ATT was good, and no treatment discontinuations were reported. 20 P R O B E • V o l .

PROBE • Vol. L • No. 3 • Apr–Jun 2011 21 Clinical Insight Septilin in infective dermatoses Septilin in Infective Dermatoses Sharma SK, et al. Dr. Ram Manohar Lohia Hospital, New Delhi. Curr Med Pract. 1984;28(8):603-606. Intro duc tion Abstract The aim of this study was to evaluate the role of Septilin in infective dermatoses. A total of 50 patients with dermatological conditions such as acne vulgaris, acne pustulosa, impetigo, infective eczema, folliculitis, and carbuncles were selected for this study. These patients were randomly selected, irrespective of age, sex, and duration of disease. Septilin was administered at a dosage of 2 tablets twice a day to 2 tablets thrice a day, depending on the age and severity of infection. The patients were followed up every week up to 4 weeks and the number of lesions, site, and type of lesions were recorded in detail. The findings of the study showed a definite improvement in cases of chronic infective dermatoses although no encouraging results were seen in acute infective dermatoses. Key Words Septilin, infective dermatoses dermatoses, chronic infective Septilin is an Ayurvedic preparation which contains antibacterial and anti-inflammatory principles.1 Septilin has been reported to stimulate phagocytosis.2 Cahu and Hirsh3 demonstrated the presence of an antibacterial protein (phagocytin) in the cytoplasmic granules of polymorphs. This protein of polymorphs has an antibacterial effect on both gram-positive and gram-negative organisms. Given orally, Septilin has been shown to inhibit the growth of staphylococci, streptococci, pneumococci, Micrococcus catarrhalis, Neisseria catarrhalis, Hemophilus influenzae, diphtheroids, and Klebsiella sps.4,5 Septilin was tried in acute and chronic infective dermatoses because it is economical and can be given for a long time without any untoward side-effects, in comparison to antibiotics which are expensive and may have side-effects. Therapeutic Ac tion of Ingre dients Balsamodendron mukul (Guggulu) has been regarded as a sovereign remedy in ancient medicine. As described in standard Ayurvedic texts, Guggulu is reputed to be an ancient “broad spectrum” drug with a wide therapeutic range. Its therapeutic action is similar to that of ACTH as it raises the general defense mechanism of the body and thus helps overcome infective and inflammatory processes. Maharasnadi quath: It is a compound containing over 20 ingredients and is useful in rheumatism, lumbago, and sciatica. Phyllanthus emblica: It is the richest natural source of ascorbic acid. The effects of vitamin C on the adrenal cortex and in building resistance to infections are well known. Tinospora cordifolia: tonic properties. This plant has diuretic and Rubia cordifolia: This plant is well known for its antipyogenic properties and is widely used externally for healing ulcers and burn wounds. 22 P R O B E • V o l . L • N o . 3 • A p r – J u n 2 0 1 1 Clinical Insight Septilin in infective dermatoses Moringa pterygosperma: The root bark of young trees contains a physiologically active, basic principle “spirochin” and an antibiotic substance “pterygospermin.” Spirochin is effective in combating gram-positive infections, specially staphylococcal and streptococcal. Pterygospermin exhibits pronounced antibacterial activity against gram-negative and gram-positive organisms. Materials and Metho ds Fifty cases of various dermatological conditions like acne vulgaris, acne pustulosa, impetigo, infective eczema, folliculitis, and carbuncles were selected. All the cases were selected at random, irrespective of age, sex, and duration of disease. Dosage of Septilin was 2 tablets twice a day to 2 tablets thrice a day, depending on the age and severity of infection. No other local medication or oral antibiotic was given. The patients were followed up every week up to 4 weeks. In few cases, clinical photographs were also taken. The patients who failed to come for a follow-up were excluded from the study and they were substituted with an equal number of new patients. The number of lesions, site, and type of lesions were recorded in detail. The results were recorded as good when there was 50% improvement in inflammation and itching. O bser vations and Re sults Study findings showed good results in 46% of cases, status quo in 44%, and deterioration in 10% (Table 1). Good results were seen in chronic infective dermatoses like acne vulgaris and chronic folliculitis. But no encouraging results were seen in acute infective dermatoses like impetigo, infective eczema, carbuncles, and furunculosis. In all the above conditions no dramatic results were seen. In the case of acne vulgaris, half the number of total cases showed improvement, there was reduction in existing pustules and cysts, as well as reduction in the number of new papules, pustules, and cystic lesion. The other half maintained status quo. These patients were followed up for 4 to 6 weeks. In cases of infective eczema, only three cases showed improvement in erythema and oozing. In 7 cases, there was no improvement at all. In 4 cases there was a increase in erythema, oozing, and crusting. In these cases, patients had to be put on other medicines after 7 to 10 days of follow-up. In case of carbuncles and furunculosis, there were not very encouraging results except in one case of sycosis barbae. Case of chronic folliculitis showed good results, with the reduction of existing lesions and also reduction in the appearance of new lesions. Summar y Fifty cases of infective dermatoses were treated with Septilin for 1 to 4 weeks, irrespective of age, sex, and duration of the inflammatory process. Septilin was given in doses of 2 tablets twice a day to 2 tablets thrice a day. No other medication was given. There was definite improvement in cases of chronic infective dermatoses. but no encouraging results were seen in acute infective dermatoses. Reference s Table 1.

PROBE • Vol. L • No. 3 • Apr–Jun 2011 23 Clinical Insight Rumalaya forte in Osteoarthritis Evaluation of the Safety and Efficacy of Rumalaya forte: A Double-Blind Clinical Trial Rastogi S, et al. Department of Orthopedics, All Indian Institute of Medical Sciences, New Delhi, India Orthopaedics Today. 2003;V(1):63-65. Abstract A double-blind clinical study was conducted to evaluate the efficacy and safety of Rumalaya forte, a polyherbal formulation in the management of osteoarthritis. Fifty patients of either sex in the age group of 50 to 65 years with clinical and radiological evidence of osteoarthritis were selected for the trial. The patients were randomly divided into two groups. Group A patients received Rumalaya forte at a dosage of 1 tablet twice daily, and Group B received a placebo at the same dosage. All symptoms along with severity and duration were recorded prior to the drug treatment. Routine blood chemistry and radiography were done before and at the end of the treatment period. Patients were followed up every 4 weeks for 6 months. At the end of 6 months, symptomatic assessment was carried out to determine the clinical efficacy of the trial drug. Results revealed that the average score for the number of joints involved before the treatment was 3.44 in Group A and 2.72 in Group B. The score was reduced from 3.44 to 1.16 in Group A and from 2.72 to 1.47 in Group B. Thus, there was 66.28% reduction in the number of joint involvements in the Rumalaya forte-treated group and 51.94% in the placebo group. In subjective symptomatic evaluation, Group A had an average score of 18.56, which reduced to 8.02 indicating 45.96% relief in various symptoms. The subjective symptomatic score in Group B reduced from 19.63 to 13.92, indicating 29.09% relief in various symptoms. Twenty of the 25 patients in Group A were satisfied with the drug and showed significant improvement in the symptoms and mobility. In Group B, only few patients expressed their satisfaction to relief in pain. Therefore, patients belonging to Group A therefore had significant alleviation of symptoms in terms of relief of pain and free mobility of the joints. No side effects were reported by any of the patients. Key Words Rumalaya forte, osteoarthritis, joints 24 P R O B E • V o l . L • N o . 3 • A p r – J u n 2 0 1 1 Intro duc tion Osteoarthritis is the most common arthritic condition affecting an increasing aging population. It is a slowly progressing joint disease with multiple etiologies involving biomechanical and genetic factors, which may contribute to the osteoarthritic lesion in the cartilage by disrupting the chondrocyte-matrix association and altering metabolic responses in the chondrocytes. Osteoarthritis is a major cause of morbidity and disability, limiting activity, and impaired quality of life, especially among the elderly. The primary complaints of patients with osteoarthritis are pain and difficulty in joint mobility. The etiology of pain is multifactorial, including inflammatory and noninflammatory causes. These multiple causes include intraosseous increase in vascular pressure, periosteal proliferation, subchondral fracture and sclerosis, ligament laxity, muscle spasm, and synovitis. The treatment includes symptomatic therapy for pain, stiffness and swelling, and therapy directed at joint structure modification leading to retardation and reversal or prevention of the disease process. Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used to alleviate the symptoms. However, these drugs are associated with an increased morbidity in older patients. This study was conducted to evaluate the efficacy and safety of Rumalaya forte, a polyherbal formulation containing extracts of important herbs like Boswellia serrata, Alpinia galanga, Commiphora wightii, Glycyrrhiza glabra, Tinospora cordifolia, and Tribulus terrestris, in patients with osteoarthritis. Materials and Metho ds Fifty patients of either sex in the age group of 50 to 65 years who attended the orthopedic outpatient department of All India Institute of Medical Sciences, New Delhi, with clinical and radiological evidence of osteoarthritis were selected for the trial. Patients on concurrent or recent steroids were included. The Institutional Ethics Committee Clinical Insight Rumalaya forte in Osteoarthritis approved the study protocol. All the patients as per the selection criteria underwent physical examination. This was a double-blind placebo-controlled trial, and the patients received the drug through random selection. Group A patients received Rumalaya forte at a dosage of 1 tablet, twice daily, and Group B received a placebo at the same dosage. All the participants provided written informed consent. All symptoms along with severity and duration were recorded prior to the drug treatment. Routine blood chemistry and radiography were done before and at the end of the treatment period. Patients were followed up every 4 weeks for 6 months. At the end of 6 months subjective (symptomatic) assessment was carried out using the scores below to determine the clinical efficacy of the trial drug. A symptomatic evaluation was done using the scoring system involving symptom scores and signs. The total score taken into consideration for evaluation was as follows: Number of joints involved : One : 1 Multiple : 2 Swelling : 2 : 1 : Joints Muscle Pain : Worse on loading: 2 Night pain: 2 Joint malfunction 2 : Limitation of mobility: average score for the number of joints involved before the treatment was 3.44 in Group A and 2.72 in Group B. The score was reduced from 3.44 to 1.16 in Group A and from 2.72 to 1.47 in Group B. Thus, there was 66.28% reduction in the number of joint involvements in the Rumalaya forte-treated group and 51.94% in the placebo group. The reduction of joint involvement was more with Rumalaya forte treatment (Table 1). Table 1.

Almost all patients had bilateral knee joint involvement with a few of them having additional joint involvement. All the patients were examined clinically at every follow-up, and analysis was carried out at 6 months. The 51.94% Table 2. Symptomatic Evaluation : Re sults 66.28% In subjective symptomatic evaluation, Group A had an average score of 18.56, which reduced to 8.02 indicating 45.96% relief in various symptoms.

In Group B, only few patients expressed their satisfaction with regard to relief in pain. None of the patients reported any adverse reaction to either Rumalaya forte or the placebo. In this double-blind placebo-controlled study, most of the patients belonging to Group A had a satisfactory outcome, in terms of relief of pain and free mobility of the joints. No side effects were reported by any of the patients. Since, the sample size in this clinical trial was very small, a larger number of patients need to be evaluated in further trials with cross-over design. PROBE • Vol. L • No. 3 • Apr–Jun 2011 25 Clinical Insight Discussion Rumalaya forte reduced the symptoms of osteoarthritic knee joint. Although there was subjective improvement in the placebo group, this was much less compared to the Rumalaya forte-treated group. Moreover, this study had a very small population size. This could be the limiting factor to obtain greater clinical significance when compared to the placebo group. This may be further confirmed in a larger number of patients with cross-over design. The important constituents of Rumalaya forte that reduce inflammation and pain are B serrata and C wightii, both resinous compounds. B serrata has been used in folk medicine to treat inflammatory conditions like arthritis and bursitis. The significant inhibition of joint swelling and control of progressive joint involvement could be attributable to B serrata. In vitro experiments have demonstrated the inhibition of synthesis of proinflammatory 5-lipo-oxygenase viz., 5-hydroxyeicosa tetranoic acid and leukotriene with boswellic acid.1 26 P R O B E • V o l . L • N o . 3 • A p r – J u n 2 0 1 1 Rumalaya forte in Osteoarthritis Our clinical trial confirms the same with early inhibition of joint swelling and pain with Rumalaya forte.2 Moreover, B serrata significantly reduces the degradation of glycosaminoglycan and checks the progressive degeneration of joints.3 Moreover, boswellic acids are specific, in terms of non-redox inhibition of leukotriene synthesis either by interacting directly with 5-lipooxygenase or blocking its translocation. C wightii also acts synergistically with B serrata to reduce inflammation and pain. T cordifolia plays a vital role of immunomodulation. Long-term use of Rumalaya forte helps in the functional aspects of joints in osteoarthritic patients, thereby improving the quality of life. Reference s 1. Ammon HPT, et al.

CARDIOLOGY Altered Cardiac Rhythm in Infants with Bronchiolitis and Respiratory Syncytial Virus Infection Vascular Disease Associated with Facet Joint Osteoarthritis Esposito S, et al. Osteoarthritis Cartilage. 2010;18(9):1127-1132. BMC Infect Dis. 2010;10:305. This study was conducted to examine whether vascular disease was associated with lumbar spine facet joint osteoarthritis (FJ OA) in a community-based population. Although the most frequent extra-pulmonary manifestations of respiratory syncytial virus (RSV) infection involve the cardiovascular system, no data regarding heart function in infants with bronchiolitis associated with RSV infection have yet been systematically collected. The aim of this study was to verify the real frequency of heart involvement in patients with bronchiolitis associated with RSV infection, and whether infants with mild or moderate disease also risk heart malfunction. A total of 69 otherwise healthy infants aged 1 to 12 months with bronchiolitis hospitalized in standard wards were enrolled. Pernasal flocked swabs were performed to collect specimens for the detection of RSV by real-time polymerase chain reaction, and a blood sample was drawn to assess troponin I concentrations. On the day of admission, all the infants underwent 24-hour Holter ECG monitoring and a complete heart evaluation with echocardiography. Patients were re-evaluated by investigators blinded to the etiological and cardiac findings four weeks after enrollment. Regardless of their clinical presentation, sinoatrial blocks were identified in 26 out of 34 (76.5%) RSV-positive patients and 1 out of 35 (2.9%) RSV-negative patients (P<.0001). The blocks recurred more than three times over 24 hours in 25 out of 26 (96.2%) RSV-positive patients and none of the RSV-negative infants. Mean and maximum heart rates were significantly higher in the RSV-positive infants (P<.05), as was low-frequency power and the low- and high-frequency power ratio (P<.05). The blocks were significantly more frequent in children with an RSV load of ≥100,000 copies/mL than in those with a lower viral load (P<.0001). Holter ECG after 28 ± 3 days showed complete regression of the heart abnormalities. RSV seemed to be associated with sinoatrial blocks and transient rhythm alterations even when the related respiratory problems were mild or moderate. Further studies are needed to clarify the mechanisms of these rhythm problems and whether they remain asymptomatic and transient even in presence of severe respiratory involvement or chronic underlying disease. Abstracts 27 Suri P, et al. This ancillary study included 441 participants from the Framingham Heart Study multidetector computed tomography (MDCT). The authors used a quantitative summary measure of abdominal aortic calcification (AAC) from the parent study as a marker for vascular disease. FJ OA was evaluated on computerized tomography (CT) scans using a four-grade scale. For analytic purposes, FJ OA was dichotomized as moderate FJ OA of at least one joint from L2-S1 versus no moderate FJ OA. The association of AAC and FJ OA was examined using logistic regression before and after adjusting for age, sex, and body mass index (BMI). Furthermore, the independent effect of AAC on FJ OA was examined after including the known cardiovascular risk factors; diabetes, hypertension, hypercholesterolemia, and smoking. Low AAC (OR 3.84 [2.33–6.34]; P≤.0001) and high AAC (OR 9.84 [5.29–18.3]; P≤.0001) were strongly associated with FJ OA, compared with the reference group. After adjusting for age, sex, and BMI, the association with FJ OA was attenuated for both low AAC (OR 1.81 [1.01–3.27]; P = .05) and high AAC (OR 2.63 [0.99–5.23]; P = .05). BMI and age were independently and significantly associated with FJ OA. The addition of cardiovascular risk factors to the model did not substantially change parameter estimates for either AAC tertile. AACs were associated with FJ OA in this community-based population, when adjusted for epidemiologic factors associated with spinal degeneration and cardiovascular risk factors. Potentially modifiable risk factors for facet degeneration unrelated to conventional biomechanical paradigms may exist.

Faden H, et al. J Hepatol. 2009;51(4):778-786. Pediatrics. 2010;125(3):e618-e624. Objective Objective The aim of this two-phase study was to study the clinical features of nonalcoholic fatty liver disease (NAFLD) in patients with psoriasis. The aim of this study was to compare rectal and nasal Staphylococcus aureus colonization rates and S aureus pulsed-field types (PFTs) for children with S aureus skin and soft-tissue abscesses and normal control subjects. Methods Phase 1: Investigation of prevalence and characteristics of NAFLD in an unselected cohort of 142 adult Italian outpatients with psoriasis vulgaris. Phase 2: Comparison of psoriasis cohort subgroup with NAFLD and an age- and body mass index-matched retrospective cohort of 125 nonpsoriasis patients with biopsy proven NAFLD. Results Based on histories, laboratory tests, and ultrasound studies, 84 (59.2%) patients showed clinical diagnosis of NAFLD; 30 patients had factors potentially associated with liver disease other than NAFLD (eg, viral hepatitis and significant ethanol and methotrexate usage); and 28 (19.7%) had normal livers. Comparison of the normal liver and NAFLD subgroups revealed that NAFLD in psoriasis patients (Ps-NAFLD) was significantly correlated with metabolic syndrome (P<.05), obesity (P = .043), hypercholesterolemia (P = .029), hypertriglyceridemia (P<.001), AST/ALT ratio >1 (P = .019), and psoriatic arthritis (PsA) (P = .036). The association with PsA remained significant after logistic regression analysis (OR = 3.94 [CI, 1.07–14.46]). Compared with the retrospective nonpsoriatic NAFLD cohort (controls), patients with Ps-NAFLD were likely to have severe NAFLD reflected by noninvasive NAFLD Fibrosis Scores and AST/ALT >1. Conclusions NAFLD is highly prevalent among patients with psoriasis, where it is closely associated with obesity (overall and abdominal), metabolic syndrome, and PsA and more likely to cause severe liver fibrosis (compared with nonPsNAFLD). Routine work-up for NAFLD may be warranted in patients with psoriasis, especially when potentially hepatotoxic drug therapy is being considered. 28 P R O B E • V o l . L • N o . 3 • A p r – J u n 2 0 1 1 Methods Sixty consecutive children with S aureus skin and softtissue abscesses that required surgical drainage and 90 control subjects were enrolled to the study. Cultures of nares and rectum were taken in both groups. S aureus isolates from all sites were characterized through multiple-locus variable-number tandem-repeat analysis, pulsed-field gel electrophoresis, staphylococcal cassette chromosome mec typing for methicillin-resistant S aureus isolates, and determination of the presence of PantonValentine leukocidin genes. Results S aureus was detected significantly more often in the rectum of children with abscesses (47%) compared with those in the control group (1%; P = .0001). Rates of nasal colonization with S aureus were equivalent for children with abscesses (27%) and control subjects (20%; P = .33). S aureus recovered from the rectum was identical to S aureus in the abscess in 88% of cases, compared with 75% of nasal isolates. PFT USA300, staphylococcal cassette chromosome mec type IV, and Panton-Valentine leukocidin genes were significantly increased in the S aureus isolates from children with abscesses compared to that from control subjects. Conclusions Skin and soft-tissue abscesses in the current epidemic of community-associated staphylococcal disease are strongly associated with rectal colonization by PFT USA300. Nasal colonization in children does not seem to be a risk factor. Abstracts GASTROENTEROLOGY Higher Prevalence of Gastrointestinal Symptoms among Patients with Rheumatic Disorders Acid-suppressive Drugs and Communityacquired Pneumonia Chong VH, Wang CL. Epidemiology. 2009;20(6):800-806. Singapore Med J. 2008;49(5):419-424. Rodríguez LA, et al. Background Chronic disorders, such as rheumatic disorders, are associated with increased gastrointestinal (GI) complaints. Medications may be a contributory factor. This study assessed the prevalence of GI symptoms among patients followed-up in a rheumatology clinic. Acid suppression may increase the risk of communityacquired pneumonia. The authors investigated this association in the United Kingdom primary care system taking account of the potential for confounding by indication. Patients were enquired about GI, psychological, and psychosomatic symptoms (headache, insomnia, anxiety, backache, and depression). Non-related visitors served as the control group. The underlying disorders were rheumatoid arthritis (RA; 37%), systemic lupus erythematosus (SLE; 23%) and others (40%). Methods The symptom prevalence of the following complaints was reduced: appetite (10.2%), nausea (20.2%), vomiting (10.7%), dysphagia (7.3%), odynophagia (5.1%), early satiety (27.5%), heartburn (15.2%), dyspepsia (44.6%), abdominal bloating (20.8%) and irregular bowel habit (6.7%). There were no differences between the various rheumatic disorders (RA/SLE and RA/others) except for more heartburn in SLE compared to others (P<.05). There was no significant difference between nonsteroidal antiinflammatory drug (NSAID) users and nonusers. Patients on medications with GI (disease modifying/steroid/ NSAIDs) adverse effects, experienced a higher rate of early satiety (odds ratio [OR] 3.5, 95% confidence interval [CI] 1.4–8.9) and dyspepsia (OR 2.1, 95% CI 1.2-4.3). Compared to the control group, patients had more GI symptoms (P<.05) except for irregular bowel habits. Patients also experienced more anxiety (OR 2.1, 95% CI 1.1-2.4) and backache (OR 2.6, 95% CI 1.6–4.2), and had significantly higher symptom clustering (>2 symptoms) compared to the controls (P<.001). GI symptoms are common among patients with rheumatic disorders. Medications alone do not account for the high prevalence, suggesting that the underlying conditions predispose to GI symptoms. The authors identified patients aged 20 to 79 years in The Health Improvement Network database with a new diagnosis of pneumonia between 2000 and 2005 (n = 7297). Cases were validated by manual review and compared with age- and sex-matched controls (n = 9993). Using unconditional logistic regression, the relative risk (RR) of pneumonia associated with current use of acidsuppressive drugs as compared to nonuse was estimated. Results Newly diagnosed community-acquired pneumonia was increased with current use of proton pump inhibitors (RR = 1.16, 95% confidence interval [CI] 1.03–1.31) but not H2-receptor antagonists (RR = 0.98, 95% CI 0.80–1.20). An increased risk of pneumonia was evident only in the first 12 months of treatment with proton pump inhibitors. There was some evidence of a dose response. Among patients taking proton pump inhibitors for <1 year, the risk of community-acquired pneumonia was stronger when current use was for dyspepsia or peptic ulcer (RR = 1.73, 95% CI 1.29–2.34) than for gastroesophageal reflux disease or prevention of upper gastrointestinal injury associated with aspirin or nonsteroidal anti-inflammatory drugs (RR = 1.22, 95% CI 0.97–1.52). Conclusions A small increase in the risk of community-acquired pneumonia associated with current proton pump inhibitor use was observed, especially during the first 12 months of treatment and at higher doses. This may be due in part to the underlying indication. PROBE • Vol. L • No. 3 • Apr–Jun 2011 29 Abstracts GYNECOLOGY Rheumatic Diseases and Pregnancy Märker-Hermann E, et al. Curr Opin Obstet Gynecol. 2010;22(6):458–465. Aim This review was conducted to discuss the effect of inflammatory rheumatic diseases (rheumatoid arthritis, ankylosing spondylitis, and systemic lupus erythematosus [SLE]) of the mother on the course of pregnancy and the development of fetus. Antirheumatic drug therapy of the mother and strategies to prevent fetal complications namely in SLE must be considered with care. Recent Findings The current literature is presented discussing hypotheses about the immunologic mechanisms leading to amelioration or exacerbation of the rheumatic symptoms in rheumatoid arthritis and ankylosing spondylitis during pregnancy. In SLE, several recent studies have been published concerning fetal complications in the antiphospholipid syndrome and in Ro/SSA-positive and La/SSB-positive mothers and how to diagnose, treat, or prevent these. Summary Today, women with inflammatory rheumatic diseases are normally fertile and can be encouraged to become pregnant, when there is a stable and quiescent phase of the disease. This is in particular important for patients with SLE, although pregnancy outcome in SLE has improved over the last decades. Pregnancy in SLE is still a high risk period during the disease course with the highest risk in women with active lupus nephritis. In contrast, women with rheumatoid arthritis develop amelioration of the rheumatic symptoms during the course of pregnancy in most cases. Female ankylosing spondylitis patients are likely to show unaltered or aggravated symptoms of back pain and impaired function. Neonatal Outcome in Obstetric Cholestasis Patients Sultana R, et al. J Ayub Med Coll Abbottabad. 2009;21(4):76–78. Background and Aim Obstetric cholestasis is a liver disease specific to pregnancy characterized by pruritus affecting the whole body, especially the palms and soles, and abnormal liver function tests. Objective of this cross-sectional study was to evaluate obstetric cholestasis as a potential risk factor for adverse neonatal outcome. The study was conducted at Department of Obstetrics and Gynecology, Unit ‘B’, Ayub Teaching Hospital, Abbottabad between April 1, 2007 and March 31, 2008. Methods All patients presenting with obstetric cholestasis irrespective of their age and parity were included in the study. Patients presenting with other causes of pruritus during pregnancy such as Hepatitis (A, B, and C), eczema, pruritus gravidarum, and herpes gestationis were excluded from the study. Patients with liver involvement due to pre-eclampsia were also excluded. Baseline investigations, liver chemistries, viral screening, liver autoimmune screen, and liver and obstetrical ultrasound were done before the diagnosis was confirmed. Patients were treated symptomatically. Neonatal outcome was calculated in terms of increased incidence of passage of meconium, preterm delivery, and fetal distress requiring delivery by cesarean section. Results The study included 30 patients. Babies of 10 patients did well after delivery, 8 required NICU care within first 24 hours of birth, and rest were delivered with low Apgar score. Two babies were delivered stillborn. Conclusion Pruritus is quite common during pregnancy with obstetric cholestasis being one of them and earlier detection of the disease allows better identification of fetuses at risk. 30 P R O B E • V o l .

Prevalence of Rheumatologic Manifestations of Chronic Hepatitis C Virus Infection among Egyptians J Viral Hepat. 2010. Mohammed RH, et al. The reason(s) that hepatitis A virus (HAV) infection may progress infrequently to acute liver failure are poorly understood. The host and viral factors were examined in 29 consecutive adult patients with HAV-associated acute liver failure enrolled at 10 sites participating in the US ALF Study Group. Clin Rheumatol. 2010;29(12):1373–1380. Eighteen out of twenty-four acute liver failure sera were PCR positive while six had no detectable virus. HAV genotype was determined using phylogenetic analysis and the full-length genome sequences of the HAV from acute liver failure sera were compared to those from self-limited acute HAV cases selected from the CDC database. It was observed that rates of nucleotide substitution did not vary significantly between the liver failure and non-liver failure cases and there was no significant variation in amino acid sequences between the two groups. Four out of 18 HAV isolates were sub-genotype IB, acquired from the same study site over a period of 3.5 years. Sub-genotype IB was found more frequently among acute liver failure cases compared to the non-liver failure cases (χ2 test, P<.01). At another center, a mother and her son presented with HAV and liver failure within one month of each other. Predictors of spontaneous survival included detectable serum HAV RNA, while age, gender, HAV genotype, and nucleotide substitutions were not associated with outcome. The more frequent appearance of rapid viral clearance and its association with poor outcomes in acute liver failure as well as the finding of familial cases implied a possible host genetic predisposition that contributes to a fulminant course. Recurrent cases of the rare sub-genotype IB over several years at a single center implied a community reservoir of infection and possible increased pathogenicity of certain infrequent viral genotypes. Chronic hepatitis C virus (HCV) viremia has been known to provoke a plethora of autoimmune syndromes referred to as extrahepatic manifestations of chronic HCV infection. Aim of the current study was to assess the prevalence of rheumatologic manifestations among Egyptians with hepatitis C infection and its association with cryoglobulin profile. The current study represents a cross-sectional study where patients with chronic HCV infection attending the outpatient clinic of the National Hepatology and Tropical Medicine Research Institute over a period of 1 year were interviewed. Patients with decompensated liver disease, on interferon therapy, having end-stage renal disease or coexisting viral infection such as patients with hepatitis B surface antibody positive were excluded from the study. Laboratory investigations as well as serological assay including cryoglobulin profile, rheumatoid factor, antinuclear antibody, and HCV-PCR were performed. Three hundred and six patients with chronic HCV infection were interviewed during this research. The overall estimated prevalence of rheumatologic manifestations in the current research was 16.39%, chronic fatigue syndrome 9.5%, sicca symptoms 8.8%, arthralgia 6.5%, fibromyalgia 1.9%, myalgia 1.3%, arthritis 0.7%, cryoglobulinemic vasculitis 0.7%, autoimmune hemolytic anemia 0.7%, and thrombocytopenia 0.7%. Xerophthalmia was significantly present in male population (P = 0.04), whereas fibromyalgia, cryoglobulinemic vasculitis, arthritis, and autoimmune hemolytic anemia were significantly present in female population in the study (P<.05). In chronic HCV genotype 4 infection, the prevalence of rheumatologic manifestations was 16.3% with chronic fatigue syndrome and sicca symptoms being the most common with no significant correlation to the degree of elevation of liver disease or viral load. PROBE • Vol. L • No. 3 • Apr–Jun 2011 31 Abstracts INFECTIONS Administrative Codes Combined with Medical Records Based Criteria Accurately Identified Bacterial Infections a mong Rheumatoid Arthritis Patients Community-associated Methicillinresistant Staphylococcus aureus (CA-MRSA) Skin Infections Patkar NM, et al. Curr Opin Pediatr. 2010;22(3):273-277. J Clin Epidemiol. 2009;62(3):321–327.e7. Objective This study was conducted to evaluate diagnostic properties of International Classification of Diseases, Version 9 (ICD-9) diagnosis codes and infection criteria to identify bacterial infections among patients with rheumatoid arthritis (RA). Study Design and Setting A cross-sectional study of RA patients with and without ICD-9 codes for bacterial infections was conducted. Sixteen bacterial infection criteria were developed. Diagnostic properties of comprehensive and restrictive sets of ICD-9 codes and the infection criteria were tested against an adjudicated review of medical records. Results Records of 162 RA patients with and 50 without purported bacterial infections were reviewed. Positive and negative predictive values of ICD-9 codes ranged from 54% to 85% and 84% to 100%, respectively. Positive predictive values of the medical records based criteria were 84% and 89% for “definite” and “definite or empirically treated” infections, respectively. Positive predictive value of infection criteria increased by 50% as disease prevalence increased using ICD-9 codes to enhance infection likelihood. Conclusion ICD-9 codes alone may misclassify bacterial infections in hospitalized patients with RA. Misclassification varies with the specificity of the codes used and strength of evidence required to confirm infections. Combining ICD-9 codes with infection criteria identified infections with greatest accuracy. Novel infection criteria may limit the requirement to review medical records. 32 P R O B E • V o l . L • N o . 3 • A p r – J u n 2 0 1 1 Odell CA. Background and Aim Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) has become increasingly important as a cause of skin and soft tissue infections (SSTIs), particularly abscesses, in patients attending the emergency department setting. The antibiotic sensitivity profile of S aureus isolates from SSTIs has changed over time in many geographic locations. Whether antibiotics are needed in the management of skin abscesses, and, if so, when, is controversial. Recent Findings A number of studies have looked at antibiotic therapy in conjunction with incision and drainage in managing abscesses. Factors evaluated were resolution of infection, need for change in antibiotic therapy, hospitalization after initial outpatient management, need for an additional drainage procedure, and recurrence of infection within 30 days after the initial incision and drainage procedure. For abscesses, clinical failure was associated with lack of adequate incision and drainage and not antibiotic use, regardless of the size of the abscess or the choice of antibiotic therapy. For other soft tissue infections, when antibiotic susceptibility data were available for the infection (impetigo or cellulitis with purulent drainage but no abscess), there was no difference in clinical resolution of MRSA infection even if the infecting organism was resistant to the antibiotic chosen for therapy. Summary CA-MRSA has become an important cause of SSTIs. Current data suggest that most abscesses can be treated successfully with incision and drainage alone. Antibiotic choice is more crucial for management of cellulitis and should be guided by the prevalence of CA-MRSA in the community and its antibiotic susceptibility profile. Abstracts NEUROLOGY Neurological Complications of Ankylosing Spondylitis: Neurophysiological Assessment Prevalence and Characteristics of Peripheral Neuropathy in Hepatitis C Virus Population Khedr EM, et al. Santoro L, et al. Rheumatol Int. 2009;29(9):1031–1040. J Neurol Neurosurg Psychiatry. 2006;77(5):626-629. Studies examining the neurological involvement of ankylosing spondylitis (AS) are limited. This study aimed to assess the frequency of myelopathy, radiculopathy, and myopathy in AS correlating them to the clinical, radiological, and laboratory parameters. The study included 24 patients with AS. Axial status was assessed using bath ankylosing spondylitis metrology index (BASMI). Patients underwent standard cervical and lumbar spine and sacroiliac joint radiography, somatosensory (SSEP) and magnetic motor (MEP) evoked potentials of upper and lower limbs, and electromyography (EMG) of trapezius and supraspinatus muscles. Patients’ mean age and duration of illness were 36 and 5.99 years, respectively. BASMI mean score was 4.6. Neurological manifestations were observed in 25% (n = 6) of patients, myelopathy in 8.3%, and radiculopathy was observed in 16.7% of patients. Ossification of the posterior (OPLL) and anterior (OALL) longitudinal ligaments were found in 8.3% (n = 2) and 4.2% (n = 1) of the patients, respectively. About 70.8% (n = 17) had ≥1 neurophysiological test abnormalities. SSEP abnormalities were observed in 12 patients (50%) and prolonged central conduction time (CCT) of median and/or ulnar nerves was observed in 7 patients, suggesting cervical myelopathy. Delayed peripheral or root latencies at Erb's or interpeak latency (Erb's-C5) were noted in 6 patients, suggesting radiculopathy. Motor evoked potentials was abnormal in 54% (n = 13). Abnormal MEP of upper and lower limbs were noted in 12 (50%) and 5 (20.8%) patients, respectively. About 50% (n = 12) of patients had myopathic features of trapezius and supraspinatus muscles. Only 8.3% (n = 2) had neuropathic features. It was concluded that subclinical neurological complications are frequent in AS as compared to clinically manifest complications. Somatosensory evoked potential and MEP are useful to identify AS patients prone to develop neurological complications. Objective To assess the prevalence of peripheral neuropathy (PN) and its correlation with cryoglobulinemia (CG) in an unselected, untreated referral hepatitis C virus (HCV) population. Patients and Methods The study included 234 patients (120 women and 114 men) with untreated HCV infection were consecutively enrolled by seven Italian centers. Clinical neuropathy was diagnosed when symptoms and signs of peripheral sensory or motor involvement were present. Median, ulnar, peroneal, and sural nerves were explored in all patients and distal symmetric polyneuropathy was diagnosed when all explored nerves or both lower limb nerves were affected. Mononeuropathy and mononeuropathy multiplex were diagnosed when one nerve or two noncontiguous nerves with asymmetrical distribution were affected. Screening for CG was done in 191 unselected patients. Results Clinical signs of PN were observed in 25 out of 234 patients (10.6%). Electrophysiological PN was found in 36 (15.3%). CG was present in 56 out of 191 patients (29.3%). The prevalence of CG increased significantly with age (P<.001) and disease duration (P<.05). PN was present in 12 out of 56 (21%) patients with CG and 18 out of 135 (13%) without CG (P = NS). PN increased significantly with age (P<.001) and logistic regression analysis confirmed age as the only independent predictor of PN (OR 1.10 for each year; 95% CI 1.04–1.15; P<.001). Conclusions Electrophysiological examination detected subclinical neuropathy in 11 patients (4.7%). Statistical analysis showed that CG was not a risk factor for PN whereas PN prevalence increased significantly with age.

Gumus K, et al. Graefes Arch Clin Exp Ophthalmol. 2006;244(11):1391– 1397. Cornea. 2009;28(9):997-1002. Objectives The aim of this study was to present a series of patients with orbital inflammatory symptoms associated with significant paranasal sinus inflammation, and to discuss the diagnostic and management modalities. Methods A retrospective, noncomparative, interventional case series of all patients diagnosed with orbital inflammatory syndrome and significant sinus inflammation, seen at two Orbital Units between January 1999 and October 2005. The clinical records of all patients were reviewed. Results Of 91 cases diagnosed with nonspecific orbital inflammatory syndrome, 6 (6.6%; 4 males, 2 females; mean age = 51±17 years) had significant sinus inflammation. Symptoms and signs were periorbital swelling and erythema, proptosis, globe displacement, and ocular motility restrictions with diplopia. On imaging, there was extraocular muscle enlargement and/or orbital fat haziness, as well as almost complete ipsilateral maxillary sinus opacification with varying degrees of opacification of adjacent sinuses. Sinus biopsy in four cases showed a nonspecific inflammatory reaction. Treatment with steroids alone (four cases) or a combination of oral antibiotics and systemic steroids (two cases) resulted in resolution of signs and symptoms within 24 to 72 hours. One case of recurrence was noted during a mean follow-up period of 9 months (range = 3–24 months), and this responded well to oral steroids. Conclusion Although uncommon, paranasal sinusitis can be associated with a nonspecific orbital inflammatory syndrome. When an infectious etiology is excluded, systemic steroids may play a major role in the management of these patients and result in prompt resolution of orbital signs and symptoms. 34 P R O B E • V o l . L • N o . 3 • A p r – J u n 2 0 1 1 Aim The aim of this study was to explore changes in ocular surface and tear function parameters in chronic hepatitis C at different stages of hepatic fibrosis. Methods Fifty-four patients with biopsy-proven chronic hepatitis C and 54 age- and sex-matched healthy control subjects without systemic hepatitis C infection were examined with the Ocular Surface Disease Index questionnaire, Schirmer with and without anesthesia, tear film breakup time, and scoring of ocular surface Lissamine green staining using modified Oxford and van Bijsterveld scoring systems and corneal fluorescein staining. Results Patients with chronic hepatitis C scored significantly worse than the control subjects on all parameters: modified Oxford scores of Lissamine green staining (5.5/3.0; P<.001), Oxford and van Bijsterveld scores (4.0/2.0; P<.001), and corneal fluorescein staining (1.5/0.0; P = .001). The chronic hepatitis C group also had higher Ocular Surface Disease Index scores than the control subjects (22.3/13.7; P = .001). Schirmer with and without anesthesia and tear film breakup time scores were found to be lower in patients with chronic hepatitis C (P<.001). Moreover, patients with advanced stages of hepatic fibrosis (stages 4–6) had significantly lower values of tear film breakup time and worse Ocular Surface Disease Index scores and ocular surface vital dye staining than those with initial stages of hepatic fibrosis (stages 0–3). Conclusion Patients with chronic hepatitis C, especially those with advanced stages of hepatic fibrosis, were more likely to exhibit severe ocular surface damage and signs of dry eye. Abstracts ORTHOPEDICS Comprehensive Rehabilitation of Patients with Rheumatic Diseases in Warm Climate: A Literature Review Prevalence of Reactivation of Hepatitis B Virus Replication in Rheumatoid Arthritis Patients Forseth KO, et al. Urata Y, et al. J Rehabil Med. 2010;42(10):897–902. Mod Rheumatol. 2011;21(1):16–23. Objective Reactivation of hepatitis B involves the reappearance of active necroinflammatory liver disease after an inactive hepatitis B surface antigen (HBsAg) carrier state or resolved hepatitis B, occurring during or after immunosuppression therapy or chemotherapy. The authors prospectively investigated the reactivation rate for hepatitis B virus (HBV) DNA replication in cases of rheumatoid arthritis (RA) with resolved hepatitis B. HBV markers were evaluated in 428 patients with RA. Patients with positive findings of HBsAg or HBV DNA at enrolment were excluded. The study population comprised 422 patients with RA, with resolved hepatitis B diagnosed in 135 patients based on HBsAg-negative and antihepatitis B core antibody/antihepatitis B surface antibody-positive results. HBV DNA was measured every 3 months in this group, and if HBV DNA became positive after enrolment, measurement was repeated every month. HBV DNA became positive (≥3.64 log copies/mL) in 7 out of 135 patients for 12 months. Use of biologic agents was significantly more frequent in patients who developed reactivation of HBV DNA replication (85.7%) than in patients who did not (36.0%, P = .008). Hazard ratios for use of biologic agents and etanercept were 10.9 (P = .008) and 6.9 (P = .001), respectively. Patients with RA, with resolved hepatitis B, need careful monitoring while receiving biologic agents, regardless of HBV DNA levels. Objective of the study was to present the evidence for the efficacy of comprehensive rehabilitation in a warm climate of patients with a wide variety of rheumatic diseases. Methods A systematic review of the literature was undertaken, searching in PubMed, CINAHL, PEDro, SweMed, and Embase from 1970 to 2010, and using the GRADE (Grading of Recommendations, Assessment, Development and Evaluation system) criteria. Results Six studies met the inclusion criteria. For patients with rheumatoid arthritis, moderate evidence was observed for reduction of disease activity, pain, fatigue, and global disease impact. Also, there was moderate evidence suggesting that comprehensive rehabilitation in warm climate did not improve fitness or reduce activity limitation beyond levels reached by rehabilitation in Scandinavia. Among patients with ankylosing spondylitis, evidence was low for reduction of disease activity, pain, joint range of motion, activity limitation, and global disease impact. In groups with mixed rheumatic diagnoses, evidence was low for reduction of pain, activity limitation, global disease impact, and improved health-related quality of life. No studies on psoriatic arthritis, osteoarthritis, fibromyalgia, or osteoporosis were found. Conclusion Well-designed studies to validate and improve the low-tomoderate evidence for the efficacy of comprehensive rehabilitation in warm climate among patients with inflammatory rheumatic disease are greatly needed.

Pediatr Int. 2007;49(2):215–219. J Pediatr Hematol Oncol. 2008;30(1):32–35. This study was conducted to retrospectively evaluate the skin and soft tissue complications secondary to procedures in acute leukemia patients with and without catheters. Eighty-seven patients with acute leukemia (acute lymphoblastic leukemia = 75 and acute myeloid leukemia = 12) were included. There were 30 patients with 37 catheter use (6 port and 31 Hickman catheter) and 57 patients without catheter. In patients with catheters, skin and soft tissue complications were seen in 20 (66%) children. The most frequent complication was cellulitis (55%). In patients without catheter, skin and soft tissue complications were seen in 37 (65%) patients. Cellulitis (37.8%) and extravasation (37.8%) were the most frequent causes. When the frequency of skin and soft tissue complications in patients with and without catheters were compared with each other, there was statistically no significant difference (P = .792). The duration of chemotherapy was significantly longer in patients who developed skin and soft tissue complications with or without catheters when compared with the duration of the therapy in patients without any skin and soft tissue complications (259.2 ± 36.3 and 218.3 ± 58.3 day, respectively; P<.0001). In pediatric leukemia patients, with or without catheters, skin and soft tissue complications are common and these complications may prolong the duration of chemotherapy.

In this study, the authors investigated lipid profile of children with acute hepatitis A (AVH) at diagnosis and recovery in order to observe the behavior of lipid parameters in such children. A total of 28 children (mean age = 8.2 ± 2.7 years) with AVH and 20 gender- and age-matched healthy children were included. In addition to the routine tests, triglyceride, cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL), plasma apo A-I and apoB were studied at diagnosis and recovery. The levels of serum triglyceride and apoB were higher (P<.01 and P<.05, respectively) and apo A-I was lower (P<.01) in patients compared to healthy children. On admission, three children had fulminant hepatic failure (FHF). Serum lipid parameters were evaluated with respect to the presence of icterus and FHF, and found that apo A-I level was lower in icteric children and LDL and apo A-I were lower in FHF compared to others (P<.05, P<.01, and P<.05, respectively). At recovery, levels of triglyceride, cholesterol, LDL, and apoB decreased (P<.01) and HDL and apo A-I increased (P<.01). Serum apo A-I level was inversely correlated with serum ammonia level but was positively correlated with serum albumin (P<.05). It was shown that serum triglyceride and apoB level increased, but apo A-I level decreased in patients with AVH. While cholestasis lowers apo A-I level, severe hepatic damage lowers both apo A-I and LDL. These parameters return to normal levels within 30 days. An interesting relationship between ammonia and apo A-I deserves further investigations, speculatively focused on hepatocyte nuclear factor 4 alpha. Abstracts PSYCHIATRY Prevalence of Anxiety and Depression in Osteoarthritis Axford J, et al. Predictors of Relapse to Significant Alcohol Drinking after Liver Transplantation Clin Rheumatol. 2010;29(11):1277–1283. Karim Z, et al. The aims of this study are to ascertain the prevalence of anxiety and depressive disorders in an outpatient population with osteoarthritis (OA), examine the interrelationships between severity of OA, pain, disability, and depression, and evaluate the Hospital Anxiety and Depression Scale (HADS) as a screening tool for this population. Patients with lower limb OA were evaluated with the Short Form McGill Pain and Present Pain Index Questionnaires, and a visual analogue scale, WOMAC Osteoarthritis Index-section C, and HADS. Participants underwent a structured clinical interview by a liaison psychiatrist (AB). X-rays of affected joints were rated for disease severity. Fifty-four patients (42 females; mean age 63.3 years) were investigated. The prevalence of clinically significant anxiety and/or depression was 40.7% (95% confidence interval [CI], 27.6–55.0). HADS was a good predictor of anxiety and depression with a sensitivity and specificity of 88% (95% CI, 64–99) and 81% (95% CI, 65–92), respectively. Pain correlated with HADS anxiety and depression scores (eg, Rank correlation coefficients [Kendall’s tau-b] between total HADS scores and Pain VAS scores 0.29; P = .003). Disability was greater in patients with depression and/or anxiety (eg, total HADS score; Kendall’s rank correlation coefficient tau-b = 0.26, P = .007) OA severity as determined by radiological score was not a good predictor for anxiety nor depression and only weakly associated with disability. Anxiety and depression are very common in OA patients. HADS anxiety was a better predictor of diagnosed anxiety than HADS depression was of diagnosed depression. HADS is a valid and reliable screening instrument for detecting mood disorder, but not a diagnostic tool or a substitute for asking about symptoms of depression. The interrelationship between mental health, pain, and disability is strong. Therefore, a multidisciplinary approach should be adopted for the management of OA. Can J Gastroenterol. 2010;24(4):245–250. End-stage alcoholic liver disease is common, with many of these patients referred for liver transplantation (LT). Alcohol relapse after LT can have detrimental outcomes such as graft loss and can contribute to a negative public perception of LT. Aim of this study was to identify factors that predict the recurrence of harmful alcohol consumption after LT. A total of 80 patients who underwent LT for alcoholic cirrhosis or had significant alcohol consumption in association with another primary liver disease, from July 1992 to June 2006 in British Columbia, were retrospectively evaluated by chart review. Several demographic-, psychosocial-, and addiction-related variables were studied. Univariate and multivariate logistic regression analyses were used to test possible associations among the variables studied and a return to harmful drinking after LT. The relapse rate of harmful alcohol consumption postliver transplant was 10%, with two patient deaths occurring directly as a result of alcohol relapse. Univariate analysis revealed relapse was significantly associated with pretransplant abstinence of less than six months (P = .003), presence of psychiatric comorbidities (P = .016), female sex (P = .019) and increased personal stressors (P = .044), while age at transplant <50 years approached significance (P = .054). Multivariate logistic regression analysis revealed the following independent factors for relapse: pretransplant abstinence of less than six months (OR 77.07; standard error 1.743; P = .013) and female sex (OR 18.80; standard error 1.451; P = .043). The findings of the present study strongly support a required minimum of six months of abstinence before LT because duration of abstinence was found to be the strongest predictor of recidivism. Female sex, younger age at transplant, and psychiatric comorbidities were also associated with relapse to harmful drinking.

Group I received distilled water; group II received Septilin at a dose of 1 g/kg (rats) or 1.5 g/kg (mice); group III received Septilin 2 g/kg (rats) or 3 g/ kg (mice) orally for 28 days. They were evaluated for immunological function on day 29 by studying weight gain, resistance against Escherichia coli sepsis, hemogram, phagocytic activity of polymorphonuclear (PMN) cells and reticuloendothelial system, delayed hypersensitivity to oxazolone, and the plaque-forming cell response of splenic lymphocytes to sheep erythrocytes. Septilin (The Himalaya Drug Company, Bangalore, India) is a herbal preparation containing powders of Balsamodendron mukul and Shankha bhasma; Maharasnadi quath; and extracts of Tinospora cordifolia, Rubia cordifolia, Emblica officinalis, Moringa pterygosperma, and Glycyrrhiza glabra. It has been reported to possess antibacterial,1 anti-inflammatory,2 and wound-healing properties.3 It is said to be helpful in treating gram-positive as well as gram-negative infections.4,5 There are reports that Septilin is effective in chronic stubborn URTI,6 tonsillitis,4 tropical eosinophilia,7 infective dermatoses,5 and dental infections. Neither of the doses of Septilin altered weight gain, absolute lymphocyte counts, or host resistance against E coli sepsis. The higher dose of Septilin reduced phagocytic activity of the PMN cells/ reticuloendothelial system, but both doses increased the percentage and absolute number of circulating neutrophils, stimulated humoral immunity, and suppressed cellular immunity. Thus, Septilin has dual effects on the immune system, with lower doses showing greater stimulant and higher doses showing predominantly suppressant effects.

In view of the various claims about the efficacy of Septilin in the treatment of infections at different sites, the present experimental study was designed to evaluate the effect of Septilin on different arms of the immune system. The experiments were performed on male albino mice weighing 20 to 30 g, except for the carbon clearance test where male albino rats weighing 150 to 200 g were used. The experimental protocol was approved by the Institutional Ethical Committee. The experimental animals were acclimatized in the laboratory animal house for at least 1 week. The animals were provided standard animal feed (Chakan Oil Mills) and tap water ad libitum. They were randomly divided into three groups. Group I received pretreatment with distilled water and acted as the control group. In group II, mice received 1.5 g/kg and rats received 1 g/kg of Septilin, while in group III, mice received 3 g/kg and rats received 2 g/kg of Septilin in the form of an aqueous suspension orally, daily for 28 days. At the end of the pretreatment phase, the animals were subjected to immunological screening using the following experimental models: resistance to E coliinduced abdominal sepsis; hemogram; carbon clearance; Preclinical Evidence Septilin in infections polymorphonuclear function; delayed hypersensitivity to oxazolone (cellular immunity); plaque-forming cell response of splenic lymphocytes to sheep erythrocytes (humoral immunity). A fresh set of animals was used for each test. Experimental Mo dels Determination of host resistance against E coliinduced abdominal sepsis8 This test was performed on male albino mice that had completed the drug pretreatment. On day 29 of the test, abdominal sepsis was induced in the test mice by challenging them, intraperitoneally, with 3x108 E coli (hospital strain), suspended in phosphate buffered saline. The test mice were observed for 24 hours and the percent mortality at 24 hours after induction of sepsis was estimated. The survivors were observed further for 7 days. Determination of hematological parameters At the end of the drug therapy, blood was collected by cardiac puncture and the total and differential WBC counts were done. Determination of phagocytic function: carbon clearance9 To evaluate the phagocytic activity of the reticuloendothelial system in vivo, a carbon clearance test was performed after completion of the drug pretreatment. On day 29, the treated rats received an intravenous injection of carbon suspension (1:50 dilution of Indian ink, Camel) at a dose of 0.5 mL/100 g body weight. Blood was withdrawn from the retro-orbital venous plexus before injection, immediately after injection, and at 5 minute intervals up to 20 minutes after injection of the carbon suspension. 0.05 mL of blood was lysed with 4 mL of 0.1% Na2CO3 and the optical density was measured spectrophotometrically at 650 nm wavelength. The results were expressed as the granulopectic index, calculated by the formula Log(OD0) – log (ODt) ------------------------- t where, OD0 is the OD at 0 min and ODt is the OD at t min. In vitro phagocytic activity of polymorphonuclear cells10 At the end of the drug treatment phase, two drops of blood were collected on a clean, dry glass slide and placed in a moist chamber to permit adherence of PMN cells, after which the clot was gently removed without disturbing the adherent PMN cells. This layer of PMNs was covered with a suspension of Candida albicans (yeast cells) (106 Candida/mL) and incubated for 1 hour. The slide was then stained with Giemsa stain and the effect of Septilin on phagocytic activity was expressed as the percentage of cells showing phagocytosis and the average number of Candida per PMN. Determination of T-lymphocyte function11-13 To determine the effect of the drugs on cell mediated immunity, the delayed hypersensitivity to oxazolone was assessed. On day 20 of drug therapy, the mice were shaved from the mid-abdominal region. 0.1 mL of a 3% solution of oxazolone sensitizing agent in ethanol was applied to this region 24 h later. Drug therapy was continued and 7 days later (ie, on day 28 of drug therapy), 0.01 mL of 3% oxazolone sensitizing agent was applied to the inner and outer aspect of the left ear after measuring the initial ear thickness with a micrometer screw gauge. After 24 hours of the challenge, thickness of the left ear was measured again. The increase in the ear thickness was taken as a measure of delayed hypersensitivity to oxazolone. Determination of B-lymphocyte function14,15 To determine the effect of the drugs on humoral immunity, the plaque-forming cell response of splenic lymphocytes to sheep erythrocytes was assessed. On day 23 of pretreatment, the mice were challenged with 1 mL of a suspension of sheep RBCs (107 RBC/mL) in saline, intraperitoneally. Drug therapy was continued until day 28. At the end of the pretreatment phase, the mice were killed and the spleen was removed and gently homogenized. The splenic lymphocytes were suspended in 10 mL of cold Hank’s gelatin solution. The number of lymphocytes per spleen was counted and 0.05 mL of this suspension of splenic lymphocytes was incubated with 0.05 mL of 8% SRBC suspension in 0.5 mL of agarose on an immunodiffusion plate at 37°C for 2 hours. Later, 1 mL of 20% fresh guinea-pig serum was surfaced on the immunodiffusion plate and incubation continued at 37°C for another 1 hour. At the end of incubation, the number PROBE • Vol. L • No. 3 • Apr–Jun 2011 39 Preclinical Evidence Septilin in infections Similarly, the granulopectic index of the reticuloendothelial system was reduced by the high dose of Septilin (P<.01) while the lower dose of Septilin did not affect it (Table 4). of plaques (clear zones) per spleen were calculated and taken as a measure of humoral immunity. Statistical analysis The results obtained in each of the treatment groups were compared with those of the control group using unpaired t test for all tests except for the host resistance against E coli-induced abdominal sepsis where the Chi square test was applied. The number of lymphocytes per spleen was not altered by either dose of Septilin. However, the number of plaque forming cells per spleen, which is a measure of humoral immunity was increased by both the doses of Septilin (low dose P<.001; high dose P<.05) (Table 5). Re sults Delayed hypersensitivity to oxazolone (cellular immunity) was reduced by both doses of Septilin (low dose P<.05; high dose P<.01) (Table 6). Measurement of body weights before and after drug treatment showed that the change in weight was not significantly different from the control group (Table 1). Similarly, neither of the doses of Septilin improved the host resistance against E coli-induced abdominal sepsis (mortality at 24 h: control 100%; low dose Septilin 83.3%; high dose Septilin 100%) (Table 2).

Studies by Kumar et al and Udapa et al have already reported the anti-inflammatory effect of Septilin.2,3 To what extent this anti-inflammatory effect could have contributed to the lesser increase in the ear thickness in response to oxazolone cannot be commented upon at this stage. In fact, there is a report where rohitukine, a compound isolated from the plant D binectariferum, showed anti-inflammatory effects in models of acute inflammation but actually enhanced delayed hypersensitivity to oxazolone.11 Thus, it appears that the anti-inflammatory effect of Septilin may have contributed only negligibly to the reduction in delayed hypersensitivity to oxazolone and that the reduction in delayed hypersensitivity must be a result of the inhibitory effect of Septilin on cell mediated immunity. Conclusion The humoral immunity was enhanced by Septilin. The increase in humoral immunity is in accordance with the studies by Bhasin et al6 where Septilin treatment increased serum IgG levels, and Sharma and Ray et al17 where Septilin increased the primary as well as secondary immune response to sheep RBCs. Septilin has dual effects on the immune system as it stimulates some of the immune functions but suppresses others. Also, it is observed that the immunostimulant effects are more prominent with the lower dose, while the immunosuppressant activity was better documented with the higher dose of Septilin. The immunomodulatory activity of drugs is known to vary with the dose level and most of the immunosuppressants show immunostimulation at low dilutions.19,20 A study by Abrams et al21 observed that administration of low doses of cyclophosphamide, an immunosuppressant, to volunteers with advanced malignancies enhanced the lymphokine activated killer cell activity induced by co-administration of interleukin-2. Similar immunostimulating properties have been found to be associated with other immunosuppressants such as glucocorticoids and 6-thioguanine.20 This suggests that immunostimulation may be a general feature of immunosuppressive drugs and a similar phenomenon may be responsible for the dual effects of Septilin, observed in the present study. Another consideration is the presence of extracts of several plants in the Polyherbal preparation Septilin, some of which may contribute to the immunostimulant and others to the immunosuppressant effects of Septilin on the immune system. Therefore, it is likely that different doses of Septilin could have different indications and this should be borne in mind while prescribing it. The cellular immunity was suppressed by Septilin. Skin test response to an antigen is complex and involves many aspects of the immune response.18 The delayed hypersensitivity that was measured here has a few major components—sensitization, release of cytokines, Finally, it was proposed that still lower doses Septilin should be studied to assess its effect the immune system and individual components the polyherbal preparation should be screened immunomodulator activity. All values are mean ± SE. a 0.01<P<.05; b0.001<P<.01. Discussion In the present study six different animal models were used to monitor the influence of Septilin on different arms of the immune system. The results show that neither of the doses studied altered weight gain, lymphocyte counts, or host resistance against acute abdominal sepsis. Both the doses of Septilin increased the percentage of neutrophils as well as the absolute number of circulating neutrophils but the higher dose reduced the phagocytic activity of the circulating polymorphonuclear cells as well as the reticuloendothelial system. This is contradictory to effects of Septilin on phagocytic function,16 which is probably because the doses used in our study are higher than the previously reported studies.

Preclinical Evidence Liv.52 Regulates Ethanol Induced PPARγ and TNF-a Expression in HepG2 Cells Mitra SK, et al. The Himalaya Drug Company, Bangalore. Mol Cell Biochem. 2008;315:9-15. Abstract Liver is a prime target of alcohol-induced damage by inducing inflammatory cytokines especially tumor necrosis factor alpha (TNF-α). Activator of peroxisome proliferator activator receptor gamma (PPARγ) is protective against alcohol-induced liver injury in animals. Liv.52, one of the major herbal hepatoprotective drugs, is shown to protect the liver from toxicity and is considered to be an effective hepatoprotective agent. However, the signal pathway involved in the Liv.52-induced hepatoprotection is not well-understood, especially in the case of cultured liver cells treated with ethanol. Hence, this study was aimed at determining whether ethanol and Liv.52 could modulate PPARγ and TNF-a induction in human hepatoma cells, HepG2. The present study with RT-PCR and confocal microscopy experiments showed that ethanol (100mM) induced suppression of PPARγ expression in HepG2 cells. The ethanol-induced PPARγ suppression was abrogated by Liv.52. Moreover, Liv.52 also induced upregulation of PPARγ mRNA in liver cells as compared to the untreated cells. Further, 100 mM ethanol has also induced TNF-α gene expression in HepG2 cells and interestingly Liv.52 abolished ethanolinduced TNF-α. The study also showed that Liv.52 is capable of attenuating ethanol-induced expression of TNF-α and abrogating ethanol-induced suppression of PPARg in liver cells. These results indicate that Liv.52-induced PPARg expression and concomitant suppression of ethanol-induced elevation of TNF-α in HepG2 cells suggest the immunomodulatory and hepatoprotective nature of Liv.52. Key Words Liv.52, TNF-α, PPARg, alcoholic liver diseases, HepG2 Intro duc tion Alcohol is one of the major hepatotoxicants. Acute or chronic alcohol consumption favors liver injuries caused by other toxins.1 Ethanol-enhanced liver injury is known to be evoked by pro-inflammatory mediators.2 Studies involving patients with alcoholic liver disease have shown increased level of TNF-α and other pro-inflammatory cytokines.3-5 Research findings from animal studies have also suggested the role of alcohol-induced TNF-α and other pro-inflammatory cytokines in causing liver injury.6 Ethanol-induced hepatotoxicity in HepG2 cells by TNF-α has been demonstrated by various studies.7,8 Peroxisome proliferator-activated receptor gamma (PPARγ) is a member of the nuclear hormone receptor superfamily and is an important transcription factor in glucose homeostasis in relation to type II diabetes.9 Although PPARγ is a wellstudied drug target for type II diabetes,10 the role of PPARγ in manifestation of inflammation is gaining momentum.11 Expression of PPARγ in hepatoma cell line indicates its potential role in liver function.12 Animal experiments have also shown the effect of ethanol in regulating PPARγ expression in liver and PPARγ agonist is found to prevent alcohol-induced liver injury.13-15 Availability of synthetic and herbal drugs is useful in protecting liver from toxicity induced by alcohol and other toxicants. Among herbal preparation, Liv.52 is one of the major herbal drug preparations for protecting liver against damage caused by various toxicants.16 Various animal experiments using different chemical toxicants have demonstrated the hepatoprotective effect of Liv.52.17-19 Liv.52-mediated liver protection from ethanolevoked toxicity was also reported from animal and human studies.19-21 However, the molecular mechanism underlying the hepatoprotective effect of Liv.52 is not explored well using suitable in vitro models, especially in the case of alcohol-induced liver toxicity. Therefore, the above information gave us impetus to determine whether Liv.52 could in any way modulate TNF-α and PPARγ expression, if any, induced by ethanol in human hepatoma cells, HepG2.

(USA). Penicillin and streptomycin were from Hi-media, India. Liquid preparation of Liv.52 was received from the Distribution unit of Himalaya Drug Company, Bangalore, India, and the details of the drug have been described previously.19 MMLV reverse transcriptase, dNTP, and Taq DNA polymerase were MBI Fermentas (USA). Cell culture conditions HepG2 were obtained from National Center for Cell Science (NCCS), Pune. These cells were maintained in Dulbecco’s Modified Essential Media (DMEM) containing 10% FBS at 37°C with 5% CO2, and 95% humidity. HepG2 cells were treated with ethanol as described previously.22,23 Unless specified, cells treated or untreated with ethanol were gently sealed with parafilm to avoid evaporation of ethanol. The cells were incubated for 24 hours at 37°C with 5% CO2. Cells sealed with and without parafilm did not show any change in the cell viability. Cytotoxicity assay Colorimetric MTT (3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyl tetrazolium bromide) assay was done to determine whether any of the test concentration of Liv.52 and ethanol has toxicity in HepG2 cells. For this, cells were seeded in 96-well flat bottom culture plates and incubated overnight. The cells were exposed to different concentration of Liv.52 and ethanol diluted in medium containing 2% FBS and incubated for 24 hours. About 10 μL MTT (5 mg/mL) was added to each well and incubated for 4 hours. The formazan dye formed was extracted with dimethyl sulfoxide and absorbance recorded as described previously.24 RNA isolation and RT-PCR HepG2 cells were seeded in 40 mm culture dishes (1x105 cells/mL) and incubated overnight. Cells were treated with ethanol (100 or 200 mM), 1% or 2% Liv.52 or together prepared in medium with 2% FBS. Treated and untreated cells were incubated for 24 hours.

Quantity and integrity of RNAs were examined with spectrophotometer and agarose gel electrophoresis, respectively. First strand cDNA was synthesized from 1 μg total RNA with oligo dT primers. Oligonucleotides used in reverse transcription polymerase chain reaction (RT-PCR) analysis and PCR amplification is from previous reports for PPARγ, For5’-GCAGGAGCAGAGCAAAGAGGTG-3’, Rev-5’AAATATTGCCAAGTCGCTGTCATC-3’, for TNF-a, For-5’–ATGAGCACTGAAAGCATGATC-3’, Rev-5’TCACAGGGCAATGATCCCAAAGTAGACCTGCCC-3’, and for GAPDH, For-5’– GACCACAGTCCATGCCATCAC-3’, Rev-5’TCCACCACCCTGTTGCTGTAG-3’.25,26 First strand cDNA was generated from total RNA using oligo dT/random hexamer primers and was amplified by PCR following the addition of specific primer pairs and Taq DNA polymerase. Human GAPDH primer set was used as a control for each RNA sample. The PCR reaction for PPARγ and GAPDH was carried out with an initial denaturation of 2 minutes at 95°C followed by 30 cycles of denaturation at 95°C for 20 seconds, annealing at 60°C for 30 seconds, and elongation at 72°C for 40 seconds. The final extension was carried out at 72°C for 10 minute. For TNF-α , the PCR conditions consisted of an initial denaturation at 94°C for 30 seconds, annealing at 60°C for 30 seconds, and elongation at 72°C for 10 minutes. Amplification products were analyzed by 1.5% agarose gel electrophoresis and visualized by ethidium bromide staining. The molecular weight of the amplified cDNA was determined by comparison with a standard molecular weight marker (1Kb ladder) and densitometry analysis was carried out for determining relative levels of PPARγ and TNF-α mRNA in comparison with GAPDH RNA. Confocal laser scanning microscope Immunfluorescence was done essentially as carried out previously.27 HepG2 cells were grown overnight on cover slips. The cells were exposed to 1% Liv.52, 100 mM ethanol, or ethanol and Liv.52 together. Untreated cells remained as controls. Treated and untreated cells were incubated for 24 hours and cells were fixed with chilled ethanol. Cells were incubated with rabbit polyclonal anti-PPARγ antibody. Secondary antibody consists of CY3 labeled anti-rabbit IgG antibody. The cover slips with cells were mounted on mounting medium and then visualized by confocal microscope (Carl Zeiss) at 63x and photomicrographs were documented. Liv.52 in alcohol-induced liver damage Data analysis Statistical analysis of data was carried out using GraphPad Prism4. Unpaired Student’s t test was used to analyze the data. Data were represented as mean ± SEM and P<.05 was considered significant. Re sults and Discussion Aim of the present study was to determine whether Liv.52 modulates any signaling pathway in HepG2 cells, which are exposed to ethanol without affecting cell viability. Hence, the model system was HepG2 cells treated with nontoxic concentration of ethanol without any detectable cytotoxicity to the cells studied for 24 hours using MTT assay. MTT assay demonstrated that both Liv.52 and ethanol were not toxic to the HepG2 cells at the tested concentration. Although we have taken wider range of concentration for ethanol and Liv.52 for cytotoxicity determination, lower concentration of ethanol (200 mM) and Liv.52 (2% and 1%) were taken for the subsequent experiments. HepG2 cells were exposed to ethanol at a concentration of 100 mM for 24 hours and looked for the mRNA expression of PPARγ. Ethanol exhibited about 0.8fold reduction in the PPARγ mRNA level in HepG2 cells as compared to the control cells and the decrease was marginally significant. Previous studies have suggested that ethanol-mediated liver injury could be regulated by PPARγ activators.13-15 These studies using animals suggest that the PPARγ agonist was found to prevent various signal pathways induced by ethanol and thereby protecting the liver from ethanol toxicity. Hence, these findings support the view that acute ethanol treatments even at a concentration 100 mM can downregulate PPARγ in the liver cells. However, when cells were exposed to ethanol and 1% or 2% Liv.52, there was 1.5- and 1.7-fold increase, respectively, in the mRNA level of PPARγ as compared to cells treated with ethanol alone (P<.05, P<.01). Interestingly, Liv.52 alone at both concentrations induced enhanced PPARγ protein expression by confocal immunofluorescence microscopy using anti-PPARγ antibody. Confocal analysis revealed increased staining of PPARγ in cells treated with Liv.52. The PPARγ expression was localized and concentrated on the perinuclear region, mainly in the cytoplasm. About 100 mM ethanol reduced the expression pattern of the PPARγ as compared to the untreated cell. But when cells were treated with ethanol and Liv.52, the PPARγ expression was increased to a greater extent as compared to the controls and cells treated with ethanol alone. It Preclinical Evidence appears there was a slight diffused translocation of PPARγ to the nucleus from the perinuclear region in cells treated with Liv.52 and ethanol. In vivo animal studies elucidated the hepatoprotective nature of Liv.52.16 Activation of PPARγ can lead to battery of cellular events especially the translocation or redistribution of PPARγ.28,29 Such cellular events seem to be specific to the cell types and nature of cell signaling initiated by agonist or antagonist.28,29 It remains to be studied whether Liv.52 could evoke any such cell-signaling event, which in turn can regulate the intracellular distribution of PPARγ in HepG2. The protective effects of Liv.52 in alcoholic patients have also been documented.21 This is the first report to suggest that Liv.52 could upregulate PPARγ expression in HepG2 cells. The anti-inflammatory effect of PPARγ has been demonstrated in various models.11 Some studies show that PPARγ activation is associated with anti-inflammatory properties30 whereas other studies show no relationship.31 Activators of PPARγ is known to protect liver and gastric mucosa from alcohol-induced injury by modulating the inflammatory mediators thus suggesting the importance of hepatic PPARγ in controlling alcohol-mediated cellular events.14,32 Hence, from the present study, it could be well argued that upregulation of PPARγ in liver cells by Liv.52 and its capacity to abrogate the ethanol-mediated suppression of PPARγ may be suggesting the protective effect of this herbal drug, Liv.52. Alcohol is known to affect the functions of hepatocytes.33 In vitro studies have shown that alcohol could induce many pro-inflammatory cytokines and mediators favoring the toxic effect of alcohol. Many laboratory studies suggest that TNF-α is a major mediator in the alcohol-mediated liver diseases.8,14,34 It was also reported that PPARγ activators could protect alcohol-induced liver injury by inhibiting TNF-α.13,14 The results obtained from this study showing the induction of PPARγ by Liv.52 gave further impetus to look into the status of TNF-α gene expression in HepG2 cells with and without ethanol exposure. It was observed that ethanol at 100 and 200 mM induced TNF-a gene expression. About 1.8-fold increase in TNF-a gene expression was observed at 100 and 200 mM ethanol (P<.01). Previous studies have demonstrated the induction of TNF-α in HepG2 cells by even 50 to 80 mM ethanol.35,36 It was further analyzed whether Liv.52 could modify ethanol-induced expression of TNF-α in HepG2 cells. The results showed that there was about 1.5-fold decrease in the TNF-α gene expression when cells were treated with Liv.52 and ethanol as compared to the TNF-α induced by the ethanol (P<.05). Interestingly, it was also PROBE • Vol. L • No. 3 • Apr–Jun 2011 45 Preclinical Evidence Liv.52 in alcohol-induced liver damage observed that Liv.52 itself could slightly downregulate the TNF-α gene expression in HepG2 cells as compared to untreated cells. Therefore, PPARγ activation by Liv.52 and inhibition of ethanol-mediated TNF-α induction in HepG2 cells by Liv.52 is suggesting the hepatoprotective activity of this herbal drug. In vivo studies have documented the protective nature of Liv.52 against liver damage induced by various types of chemicals and toxicants.16 Data are scanty to suggest the protective effect of Liv.52 in ethanolinduced liver damage in relation to pro-inflammatory mediators such as TNF-α. However, an earlier report showed that Liv.52 could decrease serum TNF-α levels in experimental hepatitis induced by carbon tetrachloride in rats.37 The induction of TNF-α in HepG2 cells by ethanol and its perturbation by Liv.52 as observed in the present study is novel information. In their experiments, authors could not detect ethanol-induced cell death in HepG2 cells observed for 24 hours. Previous studies have also shown that ethanol did not exert much toxicity to HepG2 cells incubated even for more than 24 hours.22,23 However, the induction of TNF-α by ethanol as noticed in our study and induction of many other mediators in tissues by ethanol 4,7 could be denoting the early sign of ethanol-induced deleterious effect. Hence, findings from our present in vitro studies also provide information to explore further the role of Liv.52 in ethanol-induced liver damage in relation to PPARγ and TNF-α using suitable in vivo model. Others have reported the importance of cytochrome P4502E1 (CYP4502E1) in the ethanolmediated cell death,22, 23 and hence, it would also be rational to study further the efficacy of Liv.52 in ethanolmediated toxicity in HepG2 cells expressing CY4501E1. Hence, taken together, the upregulation of PPARγ and concomitant downregulation of ethanol-mediated TNF-α expression in HepG2 cells by Liv.52 may be denoting the hepatoprotective as well as anti-inflammatory activity of Liv.52 in the liver. Conclusion 26. Matsuda T, et al. J Gen Virol. 2005;86:1055–1065. The findings from the present study suggest that Liv.52 could attenuate the TNF-α production induced by alcohol in these cells. In addition to this, interestingly this study further suggests that Liv.52 itself could suppress TNF-α production in HepG2 cells. The suppression of ethanol-induced TNF-α expression in HepG2 cells by Liv.52 as observed in the present study suggests the immunomodulatory property of Liv.52. It is interesting to observe that Liv.52 is capable of upregulating PPARγ in HepG2 cells while downregulating the TNF-α expression in the presence or absence of ethanol. 46 P R O B E • V o l .

Preclinical Evidence Immunopotentiating Activity of Septilin Praveenkumar V, et al. Amala Cancer Research Centre, Amala Nagar, Thrissur, India Indian J Exp Biol. 1997;(35):1319-1323. Abstract Intro duc tion Oral administration of Septilin (100 mg/animal/ dose; five doses) was found to enhance natural killer cell-mediated cytotoxicity and antibody-dependent cellular cytotoxicity in normal mice as well as tumorbearing mice. Septilin treatment also activated the peritoneal macrophages, which produced cytotoxicity to L929 cells. Septilin increased proliferation of bonemarrow cells and there was an increase in the number of a-naphthyl acetate esterase staining cells in the bone marrow. In addition to the activation of cellular immunity, Septilin was found to increase the number of antibody producing cells in the spleen and activation of antibody-dependent complement-mediated cell lysis. These studies justify the use of this herbal preparation in improving immunocompetence in disease states. Septilin is a proprietary Ayurvedic product of The Himalaya Drug Company, Bombay, containing various herbs and minerals.1 It is extensively used in the treatment of several acute/chronic infections.2,3 It has been demonstrated that Septilin stimulated phagocytosis and thereby helped in controlling infections.4 Recently we have shown that Septilin could increase the total count of leukocytes and the percentage of polymorphs in the peripheral blood.5 It could also protect mice from cyclophosphamide-induced myelosuppression and subsequent leukopenia.6 In the present study, the effect of Septilin on the cell-mediated and humoral immune responses in mice has been investigated. Keywords Drug Septilin, cytotoxicity, immunocompetence, infections, immune response Materials and Metho ds Pure Septilin powder was supplied by The Himalaya Drug Co., Bombay. Its main ingredients are Balsamodendron mukul, Shankha bhasma, Maharasnadi quath, Tinospora cordifolia, Rubia cordifolia, Emblica officinalis, Moringa pterygosperma, and Glycyrrhiza glabra. Drug extraction Septilin powder (6 g) was boiled in 600 mL of distilled water for 30 minutes. It was centrifuged and filtrate evaporated to dryness on a water bath and made up to 45 mL. This extract (0.75 mL) was used for oral administration and it contained the extract from 100 mg of Septilin.5 For all the experiments a total of 5 doses of this extract was given orally on alternate days unless mentioned. This concentration was found to be nontoxic.5 The control animals received an equal volume of saline. Reagents and chemicals Eagles minimum essential medium (MEM), Rosewell Park Memorial Institute medium (RPMI)-1640, and Dulbeco’s minimum essential medium (DMEM) were purchased from Hi-media Laboratories, Bombay.

Alpha-naphthyl acetate and pararosaniline were obtained from Loba chemie, Bombay, agarose from SRL Bombay. All other reagents and chemicals were of Analytical grade. Cell lines L-929 (mouse lung fibroblast) cells and YAC-1 (mouse lymphoma) cells were obtained from National Facility for Animal Tissue and Cell Culture, Pune. Ehrich ascites tumor (EAT) cells (spontaneous tumor of mammary gland of mice) were initially obtained from Cancer Institute, Bombay and were maintained as ascites tumor in Swiss albino mice. Sheep red blood cells (SRBC) were freshly collected in Alsever’s solution. Animals Female Balb/C mice 20 to 22 g (6–8 weeks old) were purchased from National Institute of Nutrition, Hyderabad. They were housed in ventilated cages in air controlled rooms. Balb/C mice were divided into four groups (20 animals/ group). Group I - normal controls; Group II - Septilintreated animals; Group III - tumor-bearing controls; and group IV - tumor-bearing animals treated with Septilin. Five doses of 0.75 mL of Septilin (equal to 100 mg powder) were given orally daily to groups II and IV. Group I received only saline. Along with the last dose, EAC (106) were injected to groups III and IV. The animals were sacrificed on various days and the spleens were processed into single cell suspension in RPMI-1640 containing 10% FCS and used as effector cells. Blood was collected from these animals by heart-puncture, sera separated and heat inactivated at 56°C for 30 minutes. Sera was used as anti-EAC antibody for ACC estimation. YAC-1 cells (106 cells) or SRBC (107 cells) were incubated along with Na2 51CrO4 (100 μCi) at 37°C for 1 hour. They were washed, suspended at a concentration of 105 cells/ mL and used as targets for NK cells (YAC-1) and ADCC (SRBC) assay as given below: The labeled target YAC-1 cells (1x104 cells/tube) were incubated with spleen cells at an effector target ratios of 100:1, 50:1, and 25:1 at 37°C for 4 hours.

SR and TR were determined by incubating the target cells alone or with HCl (IN, 100 μL), respectively. Determination of antibody-dependent cellular cytotoxic activity ADCC activity was determined using a chromium release assay described by Kim et al.8 Labeled SRBC (1x104 cells) were incubated with effector cells at different effector: target ratios of 100:1, 50:1, and 25:1 along with 0.1 mL of anti-SRBC antibody. An aliquot of the supernatant was counted for released radioactivity as above. Determination of antibody-dependent complement-mediated lysis Ehrlich ascites tumor cells (1x104 cells) were incubated with serially diluted sera sample (100 μL), and 50 μL of 1:10 diluted fresh rabbit serum as a source of complement at 37°C for 3 hours. The cytotoxicity was assessed by trypan blue exclusion method.9 Lymphocyte blastogenesis assay Lymphocyte blastogenesis assay was done as described previously10. 24 hours after the drug treatment the animals were sacrificed and spleen cells were used for lymphocytes. Controls received only saline. Spleen cells (106 cells/mL) were incubated with various concentrations of mitogens (CON A – 10 and 5 μg/mL or PHA – 6 and 3 μg/mL) at 37°C for 48 hours in 3 mL or RPMI1640 supplemented with 10% FCS after incubation 3H-thymidine (2 μCi/vial) was added to each vial and incubated for 18 hours. DNA was precipitated with 10% PCA and the amount of radioactive thymidine incorporated into DNA were counted using liquid scintillation counter (Rack Beta). Bone marrow cell proliferation assay The assay was done as described for lymphocyte proliferation assay. Instead of spleen cells, bone marrow cells (106 cells/mL) from treated and untreated animals were incubated in the presence and absence of mitogens. The amount of radioactive thymidine incorporated into the cells were used as a measure of cell proliferation. Preclinical Evidence Immunopotentiating activity of Septilin Determination of macrophage-mediated cytotoxicity heat inactivated at 56°C for 30 minutes. The titer was determined by hemagglutination method.13 Peritoneal macrophages were induced by injecting (IP) 0.2 mL of sodium caseinate (5%) on the last day of drug treatment. After 5 days, the macrophages were collected in Hank’s Balanced Salt Solution (HBSS). It was washed and suspended in DMEM containing 10% FCS at a concentration of 2.5x105 cells. Target L929 cells (5x103 cells/well) were incubated with macrophages (100 μL) from treated and untreated animals for 48 hours in a final volume of 200 μL at 37°C in a humidified atmosphere having 5% CO2. After incubation, cells were fixed and stained with crystal violet and cellular cytotoxicity was assessed morphologically.11 Re sults Determination of antibody-producing cells Effect of Septilin on antibody-dependent cellular cytotoxicity activity All animals of both treated and untreated groups (10/ group) received SRBC (2.5x108 cells) along with the last dose of Septilin. The animals from each group were sacrificed on various days and the spleen cells were used to perform Jerne’s plaque assay.12 Quantitation of circulating antibody titer Along with the last dose of Septilin treatment, all animals (6/group) received 0.1mL of 20% SRBC. Blood was collected from the tail vein prior to SRBC injection and on every third day thereafter. Sera separated and Effect of Septilin on natural killer cell activity The NK-cell activity was found to increase progressively from 48 hours after drug treatment in both Septilin treated normal and tumor-bearing mice (Figure 1 [A]). The maximum NK-cell activity was observed on day 7 with a percentage cell lysis of 55 and 58, respectively. In the case of control tumor-bearing animals the maximum NK-cell activity was observed on day 9 of tumor inoculation with a target cell lysis of 48%. ADCC was found to be enhanced in normal and tumorbearing animals after Septilin treatment (Figure 1 [B]) Maximum ADCC activity was observed on day 5 in both groups with percent target lysis of 63 and 69. In tumorbearing controls the maximum ADCC was observed on day 7 after tumor inoculation with a target, cell lysis of 47%. Effect of Septilin on antibody-dependent complement-mediated lysis activity in mice Administration of Septilin produced only a marginal increase in ACC activity in tumor-bearing animals (data not shown).

Effect of Septilin on bone marrow and spleen cell proliferation Septilin treatment significantly enhanced the proliferation of bone-marrow cells in culture (Table 1). Degree of enhancement of proliferation was nearly 10 times in animals treated with Septilin, as seen from the increased incorporation of 3H-thymidine when compared to controls. Addition of mitogens did not alter the rate of proliferation of bone-marrow cells in the treated animals.

The number of PFCs gradually increased from day 3 up to day 5 (680 PFC/106 spleen cells), which was twice the number of PFCs formed in the controls (273 PFC/106 spleen cells). There was no increase in the circulating antibody titer in Septilin-treated animals compared to controls. Discussion The data presented here demonstrate the effect of Septilin on both cellular and humoral immune response. Null cells such as NK and killer cells are lymphoid cells lacking both T- and B-cell markers. They have a great role to play in reducing the development of cancer and its metastasis.14 Oral administration of Septilin significantly enhanced NK-cell activity, ADCC, and ACC in both normal as well as tumor-bearing animals. Moreover, Septilin-activated peritoneal macrophages were highly cytotoxic to L929 cells. It has been reported that L929 cells are highly sensitive to cytotoxicity mediated by tumor necrosis factor (TNF).15 Thus the mechanism of tumor cell kill by the macrophages isolated from Septilin-treated animals may be mediated by TNF. It has already been shown that Septilin could increase the life span of tumor-bearing animals.5 Septilin was not directly cytotoxic to tumor cells. Hence, the tumor reducing activity of Septilin may be by the activation of macrophages. Septilin administration significantly enhanced proliferation of bone marrow cells from the treated animals in culture. There was also an increase in the number of cells positive for esterase (data not shown). In a previous study,6 Septilin was found to protect mice from cyclophosphamide induced myelosuppression. This may be due to the stimulation of bone marrow stem cells either directly or indirectly through augmented secretion of growth factors. In addition to the augmentation of cellular immune responses, Septilin was found to activate humoral responses. Septilin treatment enhanced the number of plaque forming cells in the spleen and marginally activated the secretion of antibodies into the circulation and ACC in mice. Septilin contains several herbomineral principles and at present we do not know the active material involved in the stimulation of the immune system. Septilin was shown to contain polysaccharides which activate properdin system, and increase chemotaxis of polymorphs at the site of infection, phagocytosis and subsequent destruction of microorganisms.17 At present we do not know the component in Septilin responsible for this action.

PROBE • Vol. L • No. 3 • Apr–Jun 2011 51 Clinical Practice Pearls 52 Prevention of Surgical-site Infections: Best Practices, Better Outcomes Dellinger EP, et al. Airway, breathing, and circulation—ABC— are important in the management of a critically ill patient. This can be done in the operating room by managing temperature, oxygen, and fluids. If these are done well and have optimal physiology, one “D” for drugs (mainly antibiotics) can be added—ABCD— for a further reduction in the risk of surgical site infections (SSIs). In addition, optimal glucose control, hair removal, antisepsis, teamwork, and surgical techniques help in reducing the risk of SSI. Box 1. Preventing SSI • ABC for critically ill patients = airway, breathing, and circulation • ABC for surgical patient = temperature, oxygen, and fluids (intravascular volume) • ABCD = temperature, oxygen, fluids, and drugs (ie, antibiotic) • ABCD plus = add glucose control and optimal processes and techniques: »» Hair removal »» Antisepsis »» Teamwork »» Surgical procedure Oxygen It is well established that the risk for SSI is closely related to the amount of oxygen available to the tissues in the wound. Patients with high levels of tissue oxygen tension have lower infection rates than expected, while those with low oxygen tensions have higher infection rates than expected. A number of studies have randomly assigned surgical patients to high and low inspired oxygen concentration (FiO2). Several randomized controlled trials have assessed 52 P R O B E • V o l . L • N o . 3 • A p r – J u n 2 0 1 1 the benefit of perioperative supplemental oxygen therapy. Although the overall results have been inconsistent, it has been observed that the use of supplemental oxygen reduces the risk of SSIs. Temperature The patient’s body temperature influences local blood flow and thus the delivery of oxygen to the wound. In a multicenter study in Germany and Austria, colorectal surgery patients were randomly assigned to be kept warm or to be allowed to get cold. A 3-fold difference was observed in the SSI rate, favoring patients who were kept warm throughout the operation and therefore maintained good blood flow and oxygen tension. Blood Transfusion Blood transfusion affects the risk of infection. The increased surgical risk increases the risk of transfusion leading to an increased risk of infection. Factors such as large tumors, difficult procedures, longer operations, lower preoperative hematocrit, and greater loss of blood that leads to hemodynamic changes and hypothermia may contribute to increased risk of infections. Hence, surgeries such as colorectal and gastric cancer surgeries, liver transplantation, coronary artery bypass surgery, hip replacement, and spinal surgery increase the risk of SSI. Blood Glucose Level Blood glucose level increases the risk of SSI. In a study, it was observed that high glucose levels were associated with an increased rate of infection, whether or not the patient was diabetic; almost half of the patients with high blood sugar levels were not diabetic. Results of another study showed that the use of insulin to control blood sugar levels in patients undergoing surgery significantly reduced the rate of SSI in patients with diabetes and it was lower than that in nondiabetic patients. The optimal level of glucose control in the perioperative period is unknown. High blood glucose levels increase the risk for SSI and other perioperative infections, and hypoglycemia increases the risk for morbidity and mortality. Clinical Practice Pearls Box 2. Optimal Perioperative Blood Glucose Level • Increased glucose level • Hypoglycemia Increased risk for SSI and other perioperative infections Increased risk for morbidity and mortality Surgical Techniques Teamwork Another factor that affects the risk of SSI is surgical technique. In recent years, it has been observed that the practice of double-gloving helps in preventing SSI from glove perforation as surgical glove perforation increases the risk for SSI. Teamwork also plays a major role in reducing the risk of SSI. There has to be accountability among all of the team members. Safety culture training such as set the behavior expectations, education of the team, and reinforcement and accountability is important. As the period of maximum influence on SSI begins and ends in the operating room, these can be prevented through appropriate use of antibiotics, antisepsis, good oxygenation, temperature control, moderate control of glucose levels, method of hair removal, and teamwork. The risk of SSI can be reduced by implementing a program to reduce the risk of either all infections through meticulous technique, avoiding shaving, and timing of antibiotic prophylaxis (horizontal program) or an infection caused by a single pathogen such as Streptococcus aureus (vertical program). A change in the surgical scrub can reduce the rate of SSI by approximately 40%, regardless of the organism, and also prevents half of the S aureus infections. S aureus infections comprise approximately 25% of SSI, so this change would reduce that rate to 12.5%. Box 3.

The huddle is an interactive discussion, in which the surgeon briefs the entire operating room team on any special concerns or challenges related to the patient’s planned operation. The patient is included if required. After a time-out to review the surgical checklist, anesthesia is induced. All team members must be empowered to advocate for the patient to ensure patient safety.

A 23-year-old homosexual man was admitted to the hospital with 5-day history of fever, malaise, and back pain with initial laboratory values showing severe transaminitis. The clinical picture was initially suggestive of acute viral hepatitis, which on further testing revealed acute hepatitis B and acute HIV coinfection. Although the patient was asymptomatic, a decision was made to start antiretroviral therapy. At 2-month follow up, liver function tests were normal with undetectable viral loads. The early treatment of acute HIV/HBV coinfections likely contributed to eventual seroconversion with immunity to HBV in a severely immunocompromised host. This is probably the first case report of acute Hepatitis B and acute HIV coinfection and its management. In conclusion, early treatment of acute hepatitis B in immunocompromised patients may be beneficial. Drug-induced Granulomatous Interstitial Nephritis in a Patient with Ankylosing Spondylitis during Therapy with Adalimumab Korsten P, et al. Am J Kidney Dis. 2010;56(6):e17-21. Abstract Tumor necrosis factor (TNF-α) inhibitors are used in the treatment of rheumatoid arthritis, psoriasis, psoriatic arthritis, Crohn disease, ankylosing spondylitis, and juvenile idiopathic arthritis. Use of TNF inhibitors is associated with the induction of autoimmunity (systemic lupus erythematosus, vasculitis, psoriasis, and sarcoidosis/ sarcoid-like granulomas). This study reports a case of interstitial granulomatous nephritis in a patient with ankylosing spondylitis after 18 months of treatment with adalimumab. Previously reported cases of sarcoid-like reactions secondary to the use of TNF-α inhibitors involved the liver, lung, lymph nodes, central nervous system, and skin. Granulomatous nephritis after adalimumab treatment has not been described. Close observation of patients undergoing treatment with TNF inhibitors for evolving signs and symptoms of autoimmunity is required. Organ involvement is unpredictable, which makes correct diagnosis and management extremely challenging.

Drug Alert 55 Hepatology. 2009;50(6):2001-2006. Background and Aim Drug-induced liver injury (DILI) is the most common cause of death from acute liver failure. The clinical presentation of DILI covers a wide spectrum, from asymptomatic liver test abnormalities to symptomatic acute liver disease, prolonged jaundice and disability, or overt acute or subacute liver failure. The aim of this study was to evaluate the number of DILI cases admitted from 1996 to 2006 and to identify the drugs responsible. Patients and Methods A database was constructed, reporting demographic, clinical features at onset, laboratory results, suspected drugs, and follow-up. Liver damage was defined as hepatocellular, cholestatic or mixed, according to clinical and laboratory data. Results Forty-six patients were admitted with a diagnosis of DILI. Presentation was jaundice in 22 patients and hepatic failure in 3 (all attributed to nimesulide). Liver damage was of a cytolytic pattern in 19 cases (41%), cholestatic in 15 (33%) and mixed in 12 cases (26%). Jaundice was found to be higher in nimesulide-induced liver damage compared to other drugs (P = .007). Three out of 14 patients with nimesulide-induced DILI developed encephalopathy and/ or ascites. Time of recovery in the nimesulide group was significantly lower than DILI from other drugs (P<.001). Conclusion Nonsteroidal anti-inflammatory drugs, psychotropic drugs and antimicrobials are the most common causes of DILI. Nimesulide-induced DILI is usually reversible upon discontinuation of the drug, but occasionally progresses to liver failure. NHSO2CH3 O Abstract Entecavir is a potent nucleoside inhibitor of the hepatitis B virus (HBV) polymerase with a high antiviral efficacy and a high genetic barrier to viral resistance. After approval in 2006, knowledge on the side effect profile in patients with advanced liver disease and impaired liver function is still limited. The study reports 16 patients with liver cirrhosis and chronic hepatitis B who were treated with entecavir. Five of these patients developed lactic acidosis during entecavir treatment. All patients who developed lactic acidosis had highly impaired liver function (model for end-stage liver disease [MELD] score ≥20). Lactic acidosis (lactate 26-200 mg/dL, pH 7.02-7.40, base excess -5 mmol/L to -18 mmol/L) occurred between 4 and 240 days after treatment initiation with entecavir. Lactic acidosis was lethal in one patient but resolved in the other cases after termination/ interruption of entecavir treatment. No increased lactate serum concentrations were observed during treatment with entecavir in the other 11 patients with chronic hepatitis B and liver cirrhosis who all had MELD scores below 18. The MELD score correlated with the development of lactic acidosis (P<.005) as well as its single parameters bilirubin, international normalized ratio, and creatinine. In contrast, Child-Pugh Score did not correlate with the development of lactic acidosis. These data indicate that entecavir should be applied cautiously in patients with impaired liver function.

Phytother Res. 2005;19(8):721-724. Asparagus racemosus (AR) Willd (family Liliaceae) is commonly known as Shatavari. The alcoholic extract of its rhizome was administered orally to adult pregnant female albino rats at a dose of 30 mg/100 g body weight, daily for 15 days (days 1-15 of gestation). The macroscopic findings revealed a prominence of the mammary glands, a dilated vaginal opening and a transversely situated uterine horn in the treated group of animals. The weight of the uterine horns of the treated group was found to be significantly higher (P<.001) but the length was shorter (P>.01). Microscopic examination of the treated group showed proliferation in the lumen of the duct of mammary gland. It was obliterated due to hypertrophy of ductal and glandular cells. Hyperplasia of the glandular and muscular tissue and hypertrophy of the glandular cells were observed in the genital organs. The parenchyma of the genital organs showed abundant glycogen granules with dilated blood vessels and thickening of the epithelial lining. The oviduct in the treated group showed hypertrophied muscular wall, whereas the ovary revealed no effect of the drug. The results suggest an estrogenic effect of Shatavari on the female mammary gland and genital organs. 56 P R O B E • V o l .

The aim of this study was to evaluate its effectiveness on insomnia through a meta-analysis of published literature. been demonstrated with quantitative or objective measurements. The authors recommend future investigations oriented toward improving insomnia with other more promising treatments. Methods Search for randomized clinical trials (RCTs) of Valerian preparations compared with a placebo on Medline, Cochrane Library, Embase, and Biosis. Outcomes: sleep-quality improvement (SQ, yes/no), sleep-quality improvement quantified through visual analogical scales (SQS) and the latency time (LT) in minutes until getting to sleep. Three meta-analyses were carried out using inversevariance weighted random effects models. Heterogeneity was determined with the Q-statistic and was explored through a sub-groups analysis. Publication bias was evaluated using the funnel plot. Valeriana wallichii Results The meta-analysis included 18 RCTs—eight had a score of 5 on Jadad’s scale. The mean differences in LT between the Valerian and placebo treatment groups was 0.70 min (95% CI, -3.44 to 4.83); the standardized mean differences between the groups measured with SQS was -0.02 (95% CI, -0.35 to 0.31); treatment with Valerian showed a relative risk of SQ of 1.37 (95% CI, 1.05-1.78) compared with the placebo group. There was heterogeneity in three meta-analyses, but it diminished in the sub groups analysis. No publication bias was detected.

J Asian Nat Prod Res. 2008;10(11-12):1045-1053. Nitric oxide (NO), derived from L-arginine, is produced by two types (constitutive and inducible) of nitric oxide synthase (NOS: cNOS and iNOS). The NO produced in large amounts by the iNOS is known to be responsible for inflammation, vasodilation, and hypotension observed in septic shock and cancer metastasis. Inhibitors of the overproduction of NO, thus, may be useful candidates for the treatment of inflammatory diseases. The authors have found that the petroleum ether extract of Saussurea lappa Decne, which is a wild species wildly distributed in India, can strongly inhibit the overproduction of NO in mouse macrophage RAW 264.7 cells. Through bioassay-guided fractionation, 13 sesquiterpenes were isolated from the active petroleum ether extract. Furthermore, another five sesquiterpenes were synthesized by chemical methods. In the present study, their effects on LPS-induced NO production and TNF-alpha release are reported. Compounds 1, 3, 9, 17, and 18 showed significant inhibitory activities on the production of NO and release of TNF-alpha with IC50 values lower than 1 micromol/L. SAR studies suggest that the exocyclic double bond (Delta(11(13))) is necessary for the inhibitory activities of sesquiterpenes on the NO production. 58 P R O B E • V o l .

J Ethnopharmacol. 2010;130(1):85-92. Background and Aim Achillea millefolium L. is a member of the Asteraceae family that is commonly referred to as “yarrow” and has been used in folk medicine against several disturbances including skin inflammations, spasmodic and gastrointestinal disorders, as well as hepato-biliary complaints. In the present study, the hydroalcoholic extract of A millefolium (HE) was evaluated for gastroprotective properties and additional mechanism(s) involved in this activity. Materials and Methods Rats were treated with HE and subsequently exposed to both acute gastric lesions induced by ethanol PA and chronic gastric ulcers induced by 80% acetic acid. Following treatment, glutathione (GSH) levels and superoxide dismutase (SOD) activity were measured. The activity of myeloperoxidase (MPO) and histological and immunohistochemical analysis were performed in animals with acetic acid-induced gastric ulcers. Achillea millefolium Results Oral administration of HE (30, 100, and 300mg/kg) inhibited ethanol-induced gastric lesions by 35%, 56%, and 81%, respectively. Oral treatment with HE (1 and 10mg/kg) reduced the chronic gastric ulcers induced by acetic acid by 43% and 65%, respectively, and promoted significant regeneration of the gastric mucosa after ulcer induction denoting increased cell proliferation, which was confirmed by PCNA immunohistochemistry. HE treatment prevented the reduction of GSH levels and SOD activity after acetic acid-induced gastric lesions. In addition, HE (10mg/kg) inhibited the MPO activity in acetic acidinduced gastric ulcers. Conclusions Results of the present study indicate that the antioxidant properties of HE may contribute to the gastroprotective activity of this extract.

Anti-inflammatory and analgesic actions B serrata is a proven potent anti-inflammatory agent as it inhibits leukotriene (LT) biosynthesis. 11-keto-boswellic acids from B serrata potently prevented TNF-induced expression and activity of matrix metalloproteinases Drug Info (MMP-3, MMP-10, and MMP-12), showing potent antiinflammatory properties both in vitro and in vivo. A galanga suppresses prostaglandin synthesis through inhibition of COX-1 and COX-2, and thus provides antiinflammatory action. T terrestris inhibits prostaglandin E2 and COX-2 activity, thus proving to be a potent anti-inflammatory agent. T cordifolia protects against lipid peroxidation by its high reactivity towards DPPH, superoxide, and hydroxyl radicals. It decreases plasma thiobarbituric acid-reactive substances and ceruloplasmin, along with an increase in glutathione and ascorbic acid. V negundo also has antioxidant action. T cordifolia reduces IL-1 production and inhibits TNF, and hence, is a potent anti-inflammatory agent. Z officinale has antioxidant effect comparable to ascorbic acid. It lowers lipid peroxidation while maintaining the activities of other antioxidant enzymes (superoxide dismutase, catalase, and glutathione peroxidase). V negundo is analgesic agent. and 3. Glycosaminoglycan-building and cartilage-protective actions Z officinale is a potent inhibitor of prostaglandinbiosynthesizing enzyme (PG synthetase) and arachidonate 5-lipoxygenase (an enzyme of LT biosynthesis), and inhibits biotransformation of arachidonic acid (AA) comparable to indomethacin. Z officinale attenuates COX-1/TX synthase (thromboxane synthase) enzymatic activity, and has inhibitory effect on COX-2 enzymes. COX-1 and 2 (regulated by the eukaryotic transcription factor NF-kappa B) are recognized as molecular targets for actions of Z officinale. Gingerol in Z officinale acts by interfering with intracellular signaling cascades, those involving NF-kappa B and mitogen-activated protein kinases. Z officinale significantly inhibits prostaglandin E2 production. Boswellic acids in B serrata lessen the degree of degradation of glycosaminoglycans (GAGs), and play an essential role in cartilage-protective action. 2. Antioxidant action The activation of macrophages by T cordifolia leads to an increase in granulocyte–macrophage colony-stimulating factor (GM-CSF), which leads to leukocytosis and improved neutrophil function. a strong anti-inflammatory C wightii (Purified) causes inhibition of nitric oxide (NO) formation, and has a scavenging effect on 2,2-diphenyl-1picryl-hydrazyl (DPPH) radicals.

PROBE • Vol. L • No. 3 • Apr–Jun 2011 67 Patient Education 68 Does Your Child Fall Sick Often? Increase your child’s immunity Why do infants or children fall sick often? Some infants who are born with defective immunity (breast feeding builds immunity in children) and young children who are constantly exposed to infections through interaction with other children in school may fall sick often. Normally, infections by bacteria and viruses in the body are kept under control by the immune system. Antibodies present in the body are capable of fighting all of them successfully. But when immune resistance is low, these organisms multiply rapidly and cause illness like common cold, fever, etc. What kind of diet can boost a child’s immunity? The optimum diet for the best immune function can be defined in three words— balance, variety, and moderation. Balance - foods should be included from all food groups including fruit, vegetable, cereal, grain, dairy product, and meat. Variety - within each food group, a variety should be consumed (eg, different kinds of fruits and vegetables). Moderation - neither too little nor too much is good for the immune system. What factors affect a child’s immune system? Some common factors • Stress (physical or emotional) - especially in the school environment, 68 P R O B E • V o l . L • N o . 3 • A p r – J u n 2 0 1 1 children are stressed by class discipline, exams, homework, peer pressure and sports performance • Stress at home and inadequate sleep can take a toll on your child’s immune system, leaving them more vulnerable to colds. • Lack of physical exercise (children who hardly play outside). • Irregular meals or improper diet. Do’s and Don’ts for boosting a child’s immunity Do’s Good nutrition is an important factor in staying healthy. • Provide food rich in vitamin C (oranges, grapes, pineapple, etc.), vitamin A (eggs, milk, cereals, etc.) and vitamin E (apple, apricots, pumpkin, chicken, vegetable oils, etc.). These vitamins are particularly beneficial for the immune system. • Your child must drink plenty of water/fluids daily and more in summer. • Have your children wash their hands several times a day - teach your children to wash their hands thoroughly and have them do so often throughout the day, especially before eating and after using the bathroom. Hand sanitizers (PureHands) are very effective, as they prevent handtransmitted infections. • Ensure children get enough sleep • Make sure your child gets plenty of fresh air and exercise through outdoor games. Patient Education Does the child need antibiotics to treat common cold that occurs often? Don’ts • Avoid letting your children share cups - germs can hang around on drinking glasses • Don’t let them share food or utensils with other kids Children fall ill due to low immunity. Boost your child’s immunity through natural methods. Antibiotics are powerful medications. They are to be used only when prescribed by a doctor. • When your child is ill, avoid all sugary foods and drinks - sugar is the worst culprit for suppressing the immune system Your doctor will know best for your child’s treatment. Do not self-medicate your child. Antibiotics may kill many bacteria, but not viruses (which cause many respiratory tract infections). • Limit TV viewing. Encourage them to play outdoors instead. If your child has a viral infection, antibiotics will not cure it. Order for FREE reprints of this article Dear Doctor, We hope you found this article useful for your patients.

N Engl J Med. 2011;364(3):236-247. The authors performed nucleic acid testing on 3.7 million blood donations and further evaluated those that were HBV DNA-positive but negative for HBsAg and anti-HBc. They determined the serologic, biochemical, and molecular features of samples that were found to contain only HBV DNA and performed similar analyses of follow-up samples and samples from sexual partners of infected donors. Seronegative HIV and HCV-positive donors were also studied. The authors identified 9 donors who were positive for HBV DNA (1 in 410,540 donations), including 6 samples from donors who had received the HBV vaccine, in whom subclinical infection had developed and resolved. Of the HBV DNA-positive donors, 4 probably acquired HBV infection from a chronically infected sexual partner. Clinically significant liver injury developed in 2 unvaccinated donors. In 5 of the 6 vaccinated donors, a non-A genotype was identified as the dominant strain, whereas subgenotype A2 (represented in the HBV vaccine) was the dominant strain in unvaccinated donors. Of 75 reactive nucleic acid test results identified in seronegative blood donations, 26 (9 HBV, 15 HCV, and 2 HIV) were confirmed as positive. Triplex nucleic acid testing detected potentially infectious HBV, along with HIV and HCV, during the window period before seroconversion. HBV vaccination appeared to be protective, with a breakthrough subclinical infection occurring with non-A2 HBV subgenotypes and causing clinically inconsequential outcomes. 70 P R O B E • V o l . L • N o . 3 • A p r – J u n 2 0 1 1 Evaluation of a New, Rapid Test for Detecting HCV Infection, Suitable for Use With Blood or Oral Fluid Lee SR, et al. J Virol Methods. 2010. The availability of a highly accurate, rapid, pointof-care test for hepatitis C virus (HCV) may be useful in addressing the problem of under-diagnosis of HCV, by increasing opportunities for testing outside of traditional clinical settings. A new HCV rapid test device (OraQuick® HCV Rapid Antibody Test), approved recently in Europe for use with venous blood, fingerstick blood, serum, plasma, or oral fluid was evaluated in a multicenter study and performance compared to established laboratorybased tests for detection of HCV. The HCV rapid test was evaluated in prospective testing of subjects with signs and/or symptoms of hepatitis, or who were at risk for hepatitis C using all 5 specimen types. Performance was assessed relative to HCV serostatus established by laboratory methods (enzyme immune assay [EIA]), recombinant immunoblot assay, and polymerase chain reaction) approved in Europe for diagnosis of hepatitis C infection. Sensitivity to antibody in early infection was also compared to EIA in 27 seroconversion panels. In addition, the reliability of the oral fluid sample for accurate detection of anti-HCV was assessed by studying the impact of various potentially interfering conditions of oral health, use of oral care products, and consumption of food and drink. In this large study of at-risk and symptomatic persons, the overall specificities of the OraQuick® were equivalent (99.6%-99.9%) for all 5 specimen types and the 95% CIs substantially overlapped. Overall sensitivities were virtually identical for venous blood, fingerstick blood, serum, and plasma (99.7%–99.9%). Observed sensitivity was slightly lower for oral fluid at 98.1% though the upper CI (99.0%) was equal to the lower CI for venous blood and fingerstick blood. Most of the HCV positive subjects which gave nonreactive results in oral fluid had serological and virological results consistent with resolved infection. Sensitivity for anti-HCV in early seroconversion was virtually identical between the HCV rapid test and EIA. Detection of anti-HCV in oral fluid appeared generally robust to conditions of oral health, consumption of food and drink and use of oral care products. The OraQuick® HCV Rapid Antibody Test demonstrated clinical performance that was equivalent to current laboratory-based EIA. Safety and Efficacy of Oral HD-03/ES* Given For Six Months in Patients with Chronic Hepatitis B Virus Infection Rajkumar JS, et al. Lifeline Rigid Hospitals, Chennai, Tamilnadu, India World J Gastroenterol. 2007;13(30):4103-4107. ABSTRACT Aim To investigate the safety and efficacy of the formulation HD-03/ES capsules in the management of patients with chronic hepatitis B infection. Methods A total of 25 patients were recruited to the study and were given HD-03/ES, two capsules twice daily for six months. Clinical assessment of symptoms and signs were done using the “clinical observation table” once a month before and after the treatment. Biochemical investigations of total bilirubin, alanine transaminase (ALT), aspartate aminotransferase (AST), and serum protein for liver function tests were done every month after initiating treatment. Serum was analyzed for HBV markers for HBsAg, HbeAg, and HBV DNA at baseline and 4 and 6 months after therapy using enzyme linked immunosorbent assay (ELISA) kits from Roche. Results After 6 months of therapy with HD-03/ES, a significant reduction in ALT values from 66.5 ± 11.1 to 39.1 ± 5.2 (P<.01) and a significant HBsAg loss (52%, P<.001), HBeAg loss (60%, P<.05) and HBV DNA loss (60%, P<.05) was observed. Adverse effects were mild and never warranted withdrawal of the drug. Conclusion The results of this pilot study indicate that HD-03/ ES might be a safe and effective treatment for chronic hepatitis B infection and a long-term multicentric comparator trial is warranted and under way. Key Words HD-03/ES, chronic hepatitis B, liver function tests, hepatitis B virus markers, clinical trial, HBsAg, HBeAg Intro duc tion Liv.52 Update 71 Hepatitis B virus (HBV) is a hepadnavirus that is noncytopathic and causes significant morbidity and mortality worldwide.1 Chronic hepatitis B (CHB) affects an estimated 400 million people worldwide with over 50,000 fatalities each year.2 About 82% of the world’s 530,000 cases of liver cancer per year are caused by viral hepatitis infection, with 316,000 cases associated with hepatitis B infection.3 According to a WHO report, India has intermediate endemicity of hepatitis B, with hepatitis B surface antigen (HBsAg) prevalence between 2% and 7% among populations studied. The prevalence does not vary significantly by region in the country. The number of HBsAg carriers in India has been estimated to be over 40 million (4 crore). It has been estimated that, in India, of the 25 million infants born every year, over one million run the lifetime risk of developing chronic HBV infection. Every year more than 100,000 people in India die due to illnesses related to HBV infection. Ayurveda, an indigenous system of medicine in India, has a long tradition of treating liver disorders with plant drugs.4 On the basis of leads available from folklore usage and recent experimental studies, HD-03/ES (a capsule formulation consisting of 125 mg each of hydroalcoholic extracts of the herbs Cyperus rotundus and Cyperus scariosus) was evolved to elicit hepatoprotective activity. Surface antigen suppression and HBV elimination activities of herbal extract containing C rotundus and C scariosus were examined using two HBsAg expressing human hepatocellular carcinoma cell *HD-03/ES is marketed as Liv.52 HB PROBE • Vol. L • No. 3 • Apr–Jun 2011 71 Liv.52 Update lines, PLC/PRF/5 and HepG2.2.215 polymerase chain reaction (PCR) for the study of amplification of DNA specific to HBV, reverse transcriptase inhibition assay, immunomodulatory effects and hepatoprotective ability against oxidative damage to hepatocytes were some of the other studies performed to evaluate the efficacy of the plant extract. The efficacy of the plant extract to eliminate the duck hepatitis B virus was assessed in experimentally infected Pekin ducks in a duck model study. Investigations indicated that the extracts could reversibly inhibit cell growth and suppress HBsAg expression in both of the human hepatocellular carcinoma cell line models. Acute and sub-acute toxicity studies conducted in rats indicated that HD-03/ES is devoid of significant toxicity following acute and repeated administration in rats. A preliminary case study report indicated that there was significant reduction of HBsAg along with disappearance of viral DNA in a patient treated with HD-03/ES at a dosage of two capsules twice daily for a period of six months.5 At the moment, there is no data to show whether HD-03/ES treatment is adequate for the treatment of HBV infection. Therefore, this clinical study was conducted to evaluate the safety and efficacy of HD-03/ES in patients with chronic hepatitis B infection. Materials and Metho ds Patients An open prospective controlled clinical trial was carried out in the Department of Gastroenterology, Lifeline Rigid Hospitals, Chennai, Tamilnadu, India, between March 2005 and June 2006 to evaluate the safety and efficacy of HD-03/ES capsules alone in the management of chronic hepatitis B infection. Informed written consent was obtained from all study participants and the protocol of the study was approved by the ethical committee of the institute. The study in general was conducted in accordance with Declaration of Helsinki and GCP Guidelines issued by the Ministry of Health, Government of India. Liv.52 HB in chronic hepatitis B Criteria for enrollment Patients, aged 18 to 60 years, with their serum alanine aminotransferase (ALT) level being 41 to 200 IU/L and who had positive serum HBsAg, were enrolled. Criteria for exclusion Patients who were more than 60 years or less than 18 years of age, pregnant or lactating women, patients who had hepatitis C or other hepatic viral infection, autoimmune hepatitis and drug-induced hepatitis or alcoholic hepatitis; patients with severe complications of cardiovascular, renal or hematopoietic system; and patients with mental disorders were excluded. Patients were excluded if they had decompensated liver disease (defined by serum albumin ≤360 g/L, bilirubin ≥150 g/L, prothrombin time ≥2 s prolonged, or a history of ascites, variceal hemorrhage or hepatic encephalopathy), pancytopenia (defined as hemoglobin <110 g/L, white cell count <4000/mm3 or platelets <105/mm3). Patients with a history of using interferon or antiviral agents or corticosteroids or immunosuppressive drugs were also excluded. Treatment Each patient was asked to take two capsules of HD-03/ ES (The Himalaya Drug Company, Bangalore, India) twice daily, two capsules in the morning and two capsules at bedtime after food for a period of six months. Recording and observation of symptoms and signs The symptoms and signs of patients were recorded in detail using the “Clinical Observation Table” once a month before and during the treatment. Etiological markers of hepatitis B Serum samples collected from patients were stored at -20oC until analysis. Serum was assayed for HBsAg, hepatitis B e-antigen (HBeAg), and HBV DNA at baseline, four and six months after therapy using commercially available enzyme-linked immunosorbent assay kits from Roche. Diagnostic criteria Liver function Patients with a history of hepatitis B or HBsAg carriers for at least 6 months, who still had symptoms and signs of hepatitis as well as abnormal liver function and positive HBsAg, were diagnosed as having CHB infection in the present study. The patients had liver function examinations every month during the treatment, including contents of serum proteins, total bilirubin (TB), and activities of ALT and aspartate aminotransferase (AST). 72 P R O B E • V o l .

Biochemical and Serological Response to 6 Months of HD-03/ES Therapy Six months of therapy with HD-03/ES capsules was markedly effective in majority of the patients as it resulted in disappearance or alleviation of chief clinical symptoms such as abdominal pain and poor appetite. The effect of six months of treatment with HD-03/ES on liver function tests are shown in Table 2. As shown in the table, there was a trend toward normalization of liver function tests in all patients treated with HD-03/ES. ALT normalization Levels of ALT before and after six months of treatment with HD-03/ES are shown in Table 3. After six months of treatment, the levels of ALT were decreased from initial value of 66.5 ± 11.1 to 39.1 ± 5.2, and this reached levels of statistical significance (P<.01). In 14 of the 25 patients (56%), ALT levels were normalized. Although ALT levels were not normalized in the remaining 11 patients, there was a trend toward reduction and in none of the patients there was a rise in ALT levels (Figure 1). 127.0 ± 7.5 Four months HD-03/ES (No. of patients) 32 Six months 56 Variable ALT normalization (%) 1.1 ± 0.5 d0 HBsAg Four months Six months D0 HBeAg Four months Six months D0 HBV DNA Four months Six months a P<.05; vs D 0; bP<.001 vs D 0 Positive 25 19 12 16 11 10 16 11 10 Negative 0 6 13b 9 14 15a 9 14 15a PROBE • Vol. L • No. 3 • Apr–Jun 2011 73 Liv.52 Update Figure 1.

List of Adverse Effects The effect of 6 months of treatment with HD-03/ES on virological response is shown in Table 3. Thirteen of the 25 patients (52%) at the end of treatment, who were treated with HD‑03/ES, had undetectable HBsAg. This difference was statistically significant (P<.001) (Figure 2). HBeAg loss (60%, P<.001) and HBV DNA loss (60%, P<.05) also occurred during treatment with HD-03/ES in those 6 patients who were positive for both HBeAg and HBV DNA initially, but were negative for the same at the end of therapy (Figures 3 and 4). Adverse effect Abdominal discomfort Fatigue Headache Insomnia Adverse events HD-03/ES was well tolerated in this study. No patient was withdrawn from therapy either for adverse effects or for other reasons. The adverse events observed during therapy are shown in Table 4. Most of the observed sideeffects were mild (fatigue, headache, and insomnia) in nature. The most common adverse event was abdominal discomfort. No serious biochemical abnormalities were experienced by any patient. 74 P R O B E • V o l .

Although the initial results of this study are promising, it remains to be seen whether virological response will be sustained during chronic Liv.52 Update Liv.52 HB in chronic hepatitis B dosing and whether relapse rates after cessation of therapy would be low unlike conventional therapies whose relapse rates are high after treatment cessation.10 Although the initial results of this study are promising, it The ultimate endpoint of antiviral therapy for CHB infection is loss of HBsAg, which is accompanied by disease remission in terms of ALT normalization.11 In this study, HBsAg loss was observed in 52% of the patients after 6 months of therapy with HD-03/ES. This is in contrast to several clinical trials of lamivudine or adefovir where HBsAg loss was not reported12,13 or tends to occur later than 24 weeks as with interferon therapy.14 Although six months of therapy is limited and not capable of inducing pronounced viral suppression, five patients lost their HBV DNA after six months of therapy, which is highly encouraging. rates after cessation of therapy would be low unlike Loss of HBeAg either spontaneously or following therapy significantly improves the clinical outcome and survival in chronic HBV patients. Therefore, HBeAg loss has remained as a major end point of antiviral therapy in chronic HBV infection. Monotherapy with alpha interferon for 16 to 26 weeks is associated with loss of serum HBeAg in 20% to 40% of the patients.15 These results (55%) are slightly better. The possible mechanisms of action as studied using HBsAg expressing human hepatocellular carcinoma cell lines PLC/PRF/5 and HepG2.2.2.15 indicate to HBsAg suppression by binding to the antigen, and HBV elimination by reverse transcriptase inhibition. Immunomodulatory effects occur by causing the release of nitric oxide (NO) by macrophages and cytokines such as TNF-a. It was found to have an hepatoprotective effect by reversing the oxidative damage caused by hepatocytes. A strong correlation was found between HBV DNA levels and histology activity index scores in HBeAg negative patients.16 As ALT levels are consistent with histological activity index scores, the findings in the present study of ALT normalization, HBsAg loss together with loss of DNA during short-term treatment with HD-03/ES indicated that patients treated with HD-03/ES may lose their infectivity faster and relapse rates would be low. remains to be seen whether virological response will be sustained during chronic dosing and whether relapse conventional therapies whose relapse rates are high after treatment cessation.17 This study has several obvious limitations including the small sample size. In summary, this trial demonstrated that 24 weeks of HD-03/ES treatment resulted in clinically significant virological and biochemical benefits in patients with CHB infection. Hence to conclude the potential benefit of HD-03/ES in the management of CHB, HD-03/ES should be studied in long-term comparative trials with standard drugs with extended duration of follow-up.

The most common symptom is back pain, but the disease can begin in peripheral joints, especially in children and women, and rarely with acute iridocyclitis (iritis or anterior uveitis). Other early signs and symptoms are diminished chest expansion from diffuse costovertebral involvement, low-grade fever, fatigue, anorexia, weight loss, and anemia. Over time, ankylosing spondylitis can fuse the vertebrae together, limiting movement. Normal anatomy Normal S-curve of spine Ankylosing spondylitis Loss of normal curvature Pott disease Pott disease, also known as tuberculous spondylitis, is a presentation of extrapulmonary tuberculosis that affects the spine, a kind of tuberculous arthritis of the intervertebral joints. The most commonly affected areas are the lower thoracic and upper lumbar vertebrae of the spine. Tuberculous involvement of the spine may 76 P R O B E • V o l . L • N o . 3 • A p r – J u n 2 0 1 1 cause serious morbidity such as permanent neurologic deficits and severe deformities. Pott disease results from hematogenous spread of tuberculosis from other sites, often pulmonary. The basic lesion involved in Pott disease is a combination of osteomyelitis and arthritis involving more than one vertebra. Progressive bone destruction may lead to vertebral collapse and kyphosis. The kyphotic deformity is caused by collapse in the anterior spine. Spondylosis Spondylosis, a common degenerative joint disease that can be very painful in some cases, refers to the degenerative osteoarthritis of the joints between the centra of the spinal vertebrae and/or neural foraminae. Aging is the primary cause of this degeneration. Discs lose their cushioning effect between the spinal bones, ligaments become weaker, and the bones may develop bony growths or spurs. In this condition the interfacetal joints are not involved. If severe, it may cause pressure on nerve roots with subsequent sensory and/or motor disturbances, such as pain, paresthesia, or muscle weakness in the limbs. Narrowing of the space between two adjacent vertebrae that compresses a nerve root emerging from the spinal cord may result in radiculopathy (sensory and motor disturbances, such as severe pain in the neck, shoulder, arm, back, and/or leg, accompanied by muscle weakness). Occasionally, direct pressure on the spinal cord (typically the cervical spine) Cervical spondylosis in may result in myelopathy (characterized by global weakness, gait dysfunction, loss of balance, and loss of bowel and/or bladder control). Spondylosis is known as cervical spondylosis when vertebrae of the neck are involved and lumbar spondylosis when lower back is involved. Spondylolysis Spondylolysis, a common clinical condition that may result in low back pain, is a specific defect in the connection between vertebrae. Patients with spondylolysis have a defect in the pars interarticularis of the neural arch that connects the superior and inferior articular facets. The most commonly affected part is the lowest lumbar vertebra (L5); however, other lumbar and thoracic Wordsmith vertebrae may also be affected. The defect can lead to small stress fractures in the vertebrae that can weaken the bones so much that one slips out of place, leading to spondylolisthesis. it. This displacement can be of a single vertebra or the Generally, spondylolysis is However when Spondylolysis asymptomatic. symptoms occur, low back pain is the most common. The pain usually spreads across the lower back, and might feel like a muscle strain. The pain is generally worse with vigorous exercise or activity. Symptoms often appear during the teenage growth spurt. Although exact cause of spondylolysis is not known, it can be either hereditary or caused due to repeated microtrauma that weakens the pars interarticularis. anterolisthesis—the upper portion of the vertebral body Spondylolisthesis Spondylolisthesis Spondylolisthesis is a condition, often associated with pain, in which a vertebra in the lower part of the spine slips out of the proper position onto the bone below whole vertebral column leading to a gradual deformity of the lower spine and narrowing of the vertebral canal. Spondylolisthesis can be categorized into two types: moves forward as compared to the rest of the lower vertebral body—and retrolisthesis—the vertebral body is displaced backwards in respect to the adjoining structure. Spondylolisthesis may be associated with symptoms such as lumbago, tight hamstring muscle, stiffness, pain in the thighs and buttocks, tenderness in the area of slipped disc, and nerve damage as a result of pressure on nerve roots causing pain radiating down the legs. Traumatic spondylopathy Traumatic spondylopathy, a form of dorsopathy, is a group of symptoms associated with spinal injury involving compression fracture of the vertebrae. The common symptoms of traumatic spondylopathy are spinal pain, changes in the shape of the spine, and weakness in the legs.

Secondary hypertrophic osteoarthropathy Hypertrophic osteoarthropathy is a syndrome of clubbing, periostitis, and synovitis. It is characterized by new subperiosteal bone formation at the distal ends of long bones. More than 95% of cases are secondary (ie, they are associated with an underlying systemic disease, most often a neoplasm or infection). Primary hypertrophic osteoarthropathy describes a case in which the cause is familial or idiopathic. Secondary hypertrophic osteoarthropathy can present with acute onset of redness, swelling, pain, and limited range of motion of the affected joints and bones. It is typically symmetric and associated with clubbing. The results of laboratory tests such as rheumatoid factor and antinuclear antibodies are normal. Periosteal new bone formation causes an elevated serum alkaline phosphatase level. If a joint effusion is present, the joint aspirate shows a noninflammatory fluid (cell count of <500 cells/μL) with a lymphocytic and monocytic predominance. Because hypertrophic osteoarthropathy is more often secondary than primary, an underlying cause must be sought. Furthermore, the only definitive therapy for secondary hypertrophic osteoarthropathy is treatment of the underlying condition. Rheumatoid arthritis is a chronic, progressive disorder that symmetrically involves the synovial and articular surfaces of multiple joints. In rheumatoid arthritis, clubbing is absent and radiography shows periosteal sparing. Primary hypertrophic osteoarthropathy, also known as pachydermoperiostosis or Touraine-Solente-Golé syndrome, is a rare autosomal dominant disorder occurring mainly in young males, characterized by hypertrophic osteoarthropathy with thickening and furrowing of facial skin (ie, leonine faces). Carpal tunnel syndrome is associated with insidious onset of hand paresthesias without any visible clinical swelling, erythema, or wrist deformity. Nerve conduction studies often help confirm the diagnosis. Acute osteomyelitis is more common in children and immunosuppressed adults. Constitutional symptoms such as fever and malaise are usually present. Skin over the affected bone may be erythematous. Positive blood cultures with an elevated erythrocyte sedimentation rate aid in the diagnosis. Radiographic images can be normal early in the disease course, in which case a nuclear bone scan or magnetic resonance imaging can assist in the diagnosis. Answer (Picture Quiz 22) Based on the patient’s history and physical examination, which one of the following is the most likely diagnosis? A. Acute osteomyelitis B. Carpal tunnel syndrome C. Primary hypertrophic osteoarthropathy D. Rheumatoid arthritis E. Secondary hypertrophic osteoarthropathy Question Picture Quiz 22 A 67-year-old man presented with pain and swelling of both wrists that began a few weeks earlier. He also reported a poor appetite and a 12 lb (5.4 kg) weight loss, as well as a productive cough and shortness of breath. He denied experiencing any morning joint stiffness, paresthesias, or other constitutional symptoms. On examination, the patient appeared ill and dyspneic. His lung examination revealed decreased breath sounds in his right upper lung field. There was broadening of the wrists with tenderness, warmth, and mild erythema along both distal forearms and wrists. Bilateral nail clubbing was also noted (see the accompanying figure). Quiz Corner History of Medicine 82 Georg Kelling (1866-1945): The Root of Modern Day Minimal Invasive Surgery John Hunter and the Origins of Modern Orthopedic Research Schollmeyer T, et al. J Orthop Res. 2007;25(4):556-560. Arch Gynecol Obstet. 2007;276(5):505-509. On September 23, 1901, at the 73rd meeting of the Society of German Natural Scientists and Physicians in Hamburg, following his lecture “On the inspection of the gullet and the stomach with flexible instruments”, the surgeon and gastroenterologist Georg Kelling from Dresden performed a laparoscopy on a dog. He called this procedure coelioscopy. Kelling’s ingenious idea to connect his oral insufflation device with the Fiedler trocar and the Nitze cystocope, led to the coelioscopy in 1901 and marked the hour of birth of laparoscopy. Until today, Georg Kelling has not experienced the appreciation he is entitled to. He is the forgotten pioneer of a method that today plays an important role in diagnostics and therapeutics. The present standard of endoscopy has confirmed the anticipations of Georg Kelling that he had hundred years ago. His name therefore deserves a fixed place in the history of medicine and especially in the history of endoscopy. Georg Kelling and his wife were killed during the heavy air raids on Dresden on February 13 and 14, 1945, but his vague footprints are still in the sands of medical history. 82 P R O B E • V o l .

John Hunter (17281793), the Founder of Scientific Surgery, was the first to engage systematically in this enterprise. Born in Scotland, Hunter moved to London to help his brother, William, run an anatomy school. This involved both the procurement and dissection of cadavers, for which activities John showed great aptitude. Further training and a spell as an army surgeon equipped him for his life’s work as a practitioner, researcher, and teacher. Hunter amassed an enormous collection of specimens displayed in a specially designed house he constructed in Leicester Square, and maintained an extensive menagerie and additional laboratories in Earl’s Court. Many of his specimens are now housed in the Hunterian Museum of the Royal College of Surgeons in London. Among Hunter’s contributions to orthopedics are his discovery of bone remodeling, and his studies on the repair and regeneration of bone, cartilage, and tendon. He developed numerous new surgical procedures, and provided detailed anatomical descriptions that often corrected existing theories. Many of his pupils became famous in their own right and two of them founded the USA’s first medical school. John Hunter died of a heart attack. Published and Perished Taff ML JAMA. 1996;275(24):1862. While walking to a lecture at Columbia University in New York City on an unusually warm and sunny afternoon last February, I passed by an open-air display in front of The Last Word bookstore on 118th Street and Amsterdam Avenue. To my amazement, my eyes came upon Dr Arthur C. Allen’s textbook: The Skin: A Clinicopathologic Treatise. I had last seen my late mentor’s “bible” of skin pathology about 20 years ago, when it was considered to be the most authoritative book on the subject. There it was—lined up with other dust-covered, out-of-print, used medical and science books. I wondered how many people had walked by the display of “All Books Outside—$1” and never blinked an eye at this oversized atlas of skin diseases. One dollar! I could not believe it. I opened the book to check its condition and was struck by the simple dedication—”To S.S.”—printed in the middle of the frontispiece surrounded by a sea of blank paper. I knew the initials stood for Sophie Spitz, Dr Allen’s wife, also a pathologist, who had died of cancer shortly before the completion of the book. I had never met Dr Spitz, but I had heard about her untimely and tragic death that left Dr Allen a young widower. I had learned from talking to others at my hospital that Dr Allen had adored his beautiful and gifted wife and was never quite the same after she died. He shied away from social events and kept to himself. Most likely, I surmised, he mourned his wife and, after her death, channeled his creative energies into finishing his textbook and reliving their time together. Both had been credited for recognizing the morphological difference between the benign juvenile melanoma and the true melanoma. Between 1948 and 1954, they published several papers, concluding that the so-called juvenile melanoma is really a benign form of a compound nevus (mole) found in childhood and not requiring aggressive therapy. I knew Dr Allen—a great diagnostician whose labor of love, published in 1954, contributed to the saving of thousands of lives. It saddened me to think how one man’s life’s work was now tossed upon a heap of old books in Upper Manhattan. I thought fondly of our days together at Brooklyn Jewish Hospital in Bedford Stuyvesant in the mid 1970s, but I was glad that he was no longer alive to see how his work was treated with such little regard. I realized that my career as a forensic pathologist has so far been successful—thanks to Dr Allen, who steered me into pathology and a reputable training program. When I was a medical student, Dr Allen was only too glad to be my mentor and share with me his knowledge of a subject he so loved. If no one else remembers him, at least I do. I learned of his death after seeing his obituary listed in the June 28, 1995, issue of JAMA: “ALLEN, Arthur Charles, 82, Brooklyn, NY; University of California, San Francisco, School of Medicine, 1936; certified by the American Board of Pathology; died October 1, 1993.” I read that obituary over and over again until it hit home that Dr Allen had actually died. Obituaries never seem to do justice to an individual’s life and work, unless the person is a celebrity who is honored with an accompanying full biography. Obits are always too short—always leaving something more to be said about a person one cared for. From Other Pages 83 Regrettably, I had lost contact with Dr Allen over the years and I had never known he was ill. It was a shock to learn that he had passed away and I had missed his funeral. I knew that by purchasing his book, I was paying my last respects to him. Now, when I see his cleaned-up atlas on the bookshelf in my library, I realize I have a memento of a man who helped me along the way. I never thought that browsing old books could evoke such emotion in me. This humbling experience reminded me of other quirks of our profession and our throwaway society. In order to climb the academic ladder, members of the medical profession are expected to do research and publish their findings. In turn, such academic endeavors should bring lasting recognition to those who strive to advance the sciences. Unfortunately, many medical writers never consider the possibility that, one day, their efforts might also end up in obscurity. The passing of Dr Allen reminds us that “fame” is not forever.

At the station, the three Aussies each buy a ticket and watch as the three New Zealanders buy just one ticket between them. “How are the three of you going to travel on only one ticket?” asks one of the Aussies. “Watch and learn,” answers one of the New Zealanders. They all board the train. The Aussies take their respective seats but all three New Zealanders cram into a toilet and close the door behind them. Shortly after the train has departed, the conductor comes around collecting tickets. He knocks on the toilet door and says, “Ticket please.” The door opens just a crack and a single arm emerges with a ticket in hand. The conductor takes it and moves on. The Aussies see this and agree it was quite a clever idea. So after the game, they decide to copy the New Zealanders on their return trip. When they get to the station, they buy a single ticket for the return trip. To their astonishment, the New Zealanders don’t buy a ticket at all!! “How are you going to travel without a ticket?” says one perplexed Aussie. “Watch and learn,” answers a New Zealander. When they board the train, the three Aussies cram into a toilet soon after which the three New Zealanders cram into another nearby. The train departs. Shortly afterwards, one of the New Zealanders leaves the toilet and walks over to the toilet where the Aussies are hiding. He knocks on the door and says, “Ticket please.” ••• Think Wise Imagination is more important than knowledge. Knowledge is limited.
