Adenoids removed for airway obstruction and/or recurrent infections have been studied to identify a possible
mechanism to explain chronicity. In this regard, macrophages may play a relevant pathogenic role as well as
neutrophils during bacterial infections and eosinophils in allergic inflammation. Therefore, this study aimed
at investigating some mediators as surrogate markers of inflammation in children who had to undergo to
adenoidectomy. Globally, 67 children (25 females, 42 males, mean age 4.9 years), affected by persistent obstruction
caused by adenoid hypertrophy were consecutively enrolled into the study. Blood samples were collected from
patients and controls to determine serum CD163, Myeloperoxidase (MPO) and ECP. There were significant
differences between patients and controls for serum CD163 (p<0.0001); MPO (p<0.0001); serum ECP (p<0.0001).
This study demonstrated some risk factors for severe AH: apnoea, recurrent respiratory infections, and high

FEV1 is considered an important parameter for asthma diagnosis and follow-up. However, it has been proposed
that FEF25-75 could be more sensitive than FEV1 to detect slight airways obstruction. Bronchial reversibility defined
by positive response to bronchodilation test. The aim of the present study was to define whether an impaired FEF25value (< 65% of predicted) may be predictive for reversibility in a large cohort of allergic children with rhinitis
75
or asthma. Six hundred allergic children were recruited: 300 with controlled asthma and 300 with allergic rhinitis.
All of them were evaluated by performing spirometry, bronchodilation test, and skin prick test. Two predictors
were significantly associated with bronchial reversibility: i) an impaired FEF25-75 value (< 65% of predicted), and ii)
sensitization to perennial allergens. It was more relevant in children with rhinitis (ORAdj:8.9 and 2.2 respectively).
In conclusion, this study, conducted in real life, could suggest that an impaired FEF25-75 value (<65% of predicted)

cohort of allergic subjects. 850 children with allergic rhinitis, allergic asthma, or both, were evaluated. Bronchial
function (FEV1, FVC, and FEF25-75), FeNO, and sensitizations were assessed. Bronchial function and FeNO were
significantly different in the 3 groups (p<0.001). A strong inverse correlation between FeNO and FEV1was found
in patients with rhinitis, asthma and asthma with rhinitis (r= -0.72, r=-0.70 and r= -0.70, respectively). Impaired
FEF25-75 values (such as <65% of predicted) were significantly associated with high FeNO levels (such as > 34 ppb).

Recently, it has been hypothesized that the oral administration of specific live probiotic strains may have
therapeutic potential in the treatment of allergic inflammation. The aim of this study was to evaluate the effect of
the oral L. reuteri DSM 17938 administration (1X108CFU), in airways allergic inflammation in mild persistent
asthmatic children. In this DBPC randomized study we selected 50 children ( 6-14 years old), affected by mild
persistent asthma (GINA step 2) and allergic to HDM. At the run-in period (T-2), the children were submitted
to medical examination, prick tests for the main respiratory allergens, spirometry and children asthma control
test (C-ACT). We selected only the children with well controlled asthma (C-ACT >19 and FEV1> 80%). After two
weeks (T0) the children were allocated into two groups, the FeNO was measured and the breath condensate was
collected. Group A children were treated with the placebo (5 drops per day) and Group B children with L. reuteri
(108CFU =5 drops per day) for 60 days. After the treatment period (T1), all patients were evaluated by medical
examination, C-ACT, spirometry, FeNO measurement and exaled breath condensate analysis. The FeNO values
showed a significant reduction (p=0,045) in L. reuteri group but not in the placebo group at the end of the treatment
(T1). Furthermore, the cytokines exam showed an increase in IL-10 levels (p<0.05) and a significant reduction in
IL-2 levels (p<0.05) only in L. reuteri group at T1. No significant differences in FEV1 values and C-ACT score
were found in both groups. In conclusion, these data showed that L. reuteri (108 CFU) was effective in reducing
bronchial inflammation in asthmatic children. No significant effect was found on FEV1 values and C-ACT score,
probably because we selected children with well controlled asthma.

propagate the inflammatory process that characterizes asthma are beginning to be understood. There is also an
evolving awareness of the active participation of structural elements, such as the airway epithelium, airway smooth
muscle, and endothelium, in this process; these structural elements within the lung and the bone marrow serve
as reservoirs for and the source of inflammatory cells and their precursors. Although often viewed as separate
mechanistic entities, so-called innate and acquired immunity often overlap in the propagation of the asthmatic
response. This review examines the newer information on the pathophysiologic characteristics of asthma and
focuses on the role of airway epithelium in the exacerbation of the disease.
Asthma is traditionally defined as a chronic disease
characterized by bronchial hyper-responsiveness (BHR)
and lung inflammation, particularly within the airways
[4-7]. Among alterations in the structure of the airways
that characterize airway remodelling, increased airway
smooth muscle (ASM) mass may represent a key feature

A potential role of Helicobater Pylori (HP) infection in several extra-intestinal pathologies has been recently
suggested. The aim of our study was to assess the role of serology positive for HP in atopic and non atopic infants
and children affected by atopic dermatitis, urticaria, rhinitis and asthma. We included 615 children affected by
atopic diseases. According to prick test positivity and age, we divided the patients into two groups: atopic or
non-atopic patients and infants (0-2 years) or children (2-12 years). The serum levels of antibodies for H. pylori
immunoglobulin G were measured by using an ELISA test. We found a not significant difference between group
1 and group 2 about atopy. There was a significant higher frequency of HP positive serology in older children. As
for infants, a higher significant prevalence of HP positive serology was found in non-atopic patients. HP positive
serology was significantly higher only in non-atopic infants affected by atopic dermatitis and urticaria than in
atopic. In group 2, non atopic children shown a significant increase in the prevalence of HP serum positivity than
atopic children. As for asthma, there was an higher prevalence of HP serology positive in non atopic asthmatic
children group than in atopic asthmatics. On the contrary, the prevalence of positive HP serology was not
significantly different between atopic and non atopic children affected by dermatitis, urticaria, and rhinitis. The
present data confirm an inverse association between HP positive serology and atopy in both groups. However, the
higher prevalence of positive HP serology was observed in non atopic asthmatics children than in atopic asthmatics.
Vol. 26, no. 1 (S), 53-61 (2012)
We could speculate that HP infection can favour non atopic asthma onset.

The aim of the present work was to assess the prevalence of early cardiac involvement in children with celiac
disease (CD), and the impact of a gluten free diet (GFD) on this issue. Sixty CD children was compared with
a control group of 45 healthy children by an echocardiographic examination. CD patients were re-evaluated
1-year after 1-year GFD. Main outcome measures were ejection fraction (EF), fractional shortening (FS), left
ventricular end-diastolic diameter (LVDD), left ventricular end-systolic diameter (LVSD), any regurgitating valve
lesions. Mild cardiac involvement was found in 13 CD children and in one control (21.7% vs. 2.2%; p=0.003),
and was secondary to regurgitation of mitral valve, aortic valve, pulmonary and tricuspid valve, or to impaired
ejection fraction. CD children as compared to controls had significantly lower contractility indices, and higher left
ventricular dimensions. In patients adhering to the GFD all valve regurgitations resolved, and the echocardiographic
parameters significantly improved. Subclinical cardiac involvement in CD children is quite frequent, and GFD
may exert a beneficial effect on the overall cardiac performance.

Nasal polyposis is a chronic inflammatory disease affecting the nasal cavity and the paranasal sinuses. It is a
relatively common disease, occurring in 1-4% of the general population, but it is rarely described in the pediatric
population. Most of the published series include children presenting with other underlying systemic diseases,
mainly cystic fibrosis. The aim of the present study was to describe the characteristics of the patients suffering
from nasal polyposis, evaluated at the Pediatric Clinic of the University of Pavia (Italy) over the last 17 years. 56
consecutive pediatric patients referring to our Pediatric Department had a diagnosis of nasal poyposis over the
last 17 years. All children underwent allergy evaluation, nasal endoscopy, CT scan of the paranasal sinus, and
Functional Endoscopic Sinus Surgery. The mean age of the present cohort was of 11.8 years and most of the patients
were male. 50% of the patients presented with unilateral, polyposis, mostly with a diagnosis of antrochoanal polyp.
4 patients presenting with bilateral polyposis suffered from cystic fibrosis. Main symptoms at diagnosis included
nasal obstruction, snoring and rhinorrhea 32% of the patients presented at least a positivity to skin prick test, for
major inhalant and food allergens. Nasal polyposis in children could represent an alert sign for other underlying
systemic diseases. Nasal endoscopy should therefore be prescribed when a diagnosis is suspected. To properly
treat a patient presenting with nasal polyposis, it is necessary to integrate medical and surgical skills through a
multidisciplinary approach.

IgA, a reduced number of inflammatory cells infiltrating target organs, as well as a reduction of eosinophilic
cationic protein and a very heterogenous influence on T cells in the peripheral blood in terms of T cell suppression

The aim of the study was to evaluate fasting levels of glucose, insulin, leptin, total ghrelin, and obestatin in a
group of prepubescent obese children before and after weight loss. We enrolled 64 prepubescent obese children,
but only 35 completed the study (mean age 7.6 ± 0.9 years, 19 females) and 20 normal-weight prepubescent
children as controls. Fasting plasma concentration of glucose, insulin, Homeostasis Model assessment for insulin
resistance (HOMA-IR), and leptin, total ghrelin, and obestatin levels were measured at baseline and after a
6-month lifestyle intervention (i.e. improved nutrition and increased physical activity). At baseline, obese children
showed significantly (p<0.001) higher leptin and obestatin levels, and lower total ghrelin concentrations than
control subjects. Weight loss significantly (p<0.001) diminished plasma leptin and insulin levels and increased
ghrelin and obestatin concentrations. Weight loss in prepubescent children is associated with a significant change
in leptin, ghrelin and obestatin concentrations. These results confirm the hypothesis that levels of these hormones

symptoms (allergic rhinitis and/or bronchial asthma); thirty-six patients
(26%) showed dermatitis
associated with respiratory allergy (allergic rhinitis and/or bronchial asthma). PTX3 levels were higher in children
with AD and there was a significant correlation between serum PTX3 levels and SCORAD index (p-value=0.0001,
rho=0.658). Therefore, this study may show that PTX3 might be a reliable marker for the severity of AD in children
with respiratory allergy.
Atopic dermatitis (AD) is an inflammatory skin
disease characterized by pruritus and chronic or relapsing
eczematous lesions that commonly present during early
infancy and affect up to 16% of children (1). AD is thought
to represent an interaction between both genetic and
environmental influences with trigger factors, including
leads to the development of a new population of Th9 cells
producing IL-9 and IL-10 (3).
Therefore, an immune-mediated inflammatory reaction
is involved in the pathogenesis of AD. In this regard,

Allergic disorders are typically characterized by an inflammatory response to allergen exposure. PTX3
behaves as an acute-phase response protein as there is a relationship between PTX3 plasma levels and disease
severity. Therefore, this study was designed to investigate a possible role of PTX3 in children with allergic rhinitis.
One hundred patients (28 females, 72 males, median age 11 years) were enrolled in the study. All patients were
monosensitized: 43 (43%) to seasonal allergens (Graminaceae), 57 (57%) to perennial allergens (house dust mites,
cat and dog epithelium, alternaria tenuis). Patients’ blood samples for assessing serum PTX3 levels were performed
during the spring. Children with rhinitis had higher PTX3 levels and there was a significant relationship between
symptom severity and serum levels. Therefore, this study shows that PTX3 serum levels could be a reliable marker
for symptom severity in children with allergic rhinitis.

OAS patients had higher SI, circulating eosinophils, and IgE levels. Thus, this study confirms the previous report
and underlines the relevance of measuring recombinant birch allergen as higher values may suggest a reliable
prediction of OAS.

Hypersensitivity reactions after immunization with tetanus toxoid are occasionally observed in atopic and
non-atopic individuals. High IgE levels in infancy may predict subsequent allergy. The aims of this study were:
i) to evaluate the role of specific IgE to tetanus toxoid in children in response to tetanus immunization and the
possible factors associated with specific IgE levels, and ii) to investigate the correlation between specific IgE levels
to tetanus toxoid and the late development of allergy (up to 12 years). Initially, 278 healthy infants (152 males and
126 females, aged 12 months) living in an urban city were screened for serum total IgE and specific IgE to tetanus
toxoid, after having obtained informed consent from parents. After 12 years, 151 children could be evaluated. Total
IgE summed with tetanus specific IgE were significantly associated with allergy at 12 years. In conclusion, this

children
(97 males,

age
7.3 years). Asthma diagnosis, severity assessment and treatment were performed according to GINA guidelines.
Twenty-one patients with non-controlled asthma presented with endoscopic features of sinusitis, but without
any clinical sign or symptom. We defined such condition occult sinusitis. Not only overt sinusitis, but also occult
sinusitis could be a significant comorbidity in asthmatic patients. For this reason, it may be beneficial to determine
the presence of sinus inflammation in children with non-controlled asthma, even when they don’t present clinical
signs or symptoms of upper airways involvement.
Sinusitis represents a frequent co-morbidity in patients
suffering from asthma and some studies pointed out that
there could be an association between these two diseases
(1-3). Upper respiratory airways diseases may induce a
hyperreactivity (6). Clinical manifestations include dry
cough, expiratory wheezing, chest tightness and dyspnoea,
which are triggered by several exogenous factors, such
as allergens, infections, airways irritants and overall in
