Abstract
Asthma is a common chronic inflammatory disorder of the lower respiratory airways in childhood. The management of asthma exacerbations and the disease control are major concerns for clinical practice. The Global Strategy for Asthma Management and Prevention, published by GINA, updated in 2017, the British Thoracic Society/Scottish Intercollegiate Guideline Network, revised in 2016, the National Institute for Health and Care Excellence asthma guideline consultation, available in 2017, are widely accepted documents, frequently implemented, with conflicting advices, and different conclusion on asthma definition and treatment. An International Consensus on Pediatric Asthma was carried out in 2012 by a Committee with expertise in the field, to critically review differences on current guidelines. In addition, the specific issue of treating severe and difficult asthma has been recently highlighted throughout the International European Respiratory Society/American Thoracic Society guidelines on severe asthma. The aim of this paper is to describe conventional treatments and some new therapeutic approaches to pediatric asthma according to guidelines, highlighting key aspects, and differences on proposed clinical recommendations for asthma management. Age specific therapy are proposed in steps, according to clinical severity and the level of disease control. If control is not achieved within 3 months, stepping-up should be considered; otherwise, if control is achieved after 3 months, stepping down may be considered. The most used drug classes of asthma medications are beta-2 adrenergic agonists, corticosteroids, and leukotriene modifiers. Intramuscolar triamcinolone has been used for severe asthma treatment. Chromones and xanthines have been extensively used in the past, but they have shown limits related to their efficacy and safety profile. Omalizumab, a monoclonal antibody against IgE, is an immunomodulatory biological agent, used as new drug in patients with confirmed IgE-mediated allergic asthma, only for patient's specific range of total IgE level. There are low evidences in the efficacy of metotrexate, as well as macrolide antibiotics in children with asthma. Antifungal agents are also not recommended in asthmatic patients. Non-pharmacological measures that may improve patient's quality of life should also be attempted. We conclude that treatment decisions on childhood asthma management should be critically made, pondering the differences suggested by agreed international consensus documents.

Abstract
The pathophysiology of asthma is complex and involves a number of factors including atopy and bronchial hyperreactivity. A strong body of evidence suggests that structural and functional respiratory epithelial alterations play a crucial role in both development and persistence of this condition. From the onset of symptoms the airways epithelium of asthmatic patients seems to be altered and unable to repair. The interactions between the epithelium and the underlying mesenchyma, which are jointly referred to as the epithelial-mesenchymal trophic unit (EMTU), are thought to result in a self-sustaining damage of the airways and, ultimately, in a chronic inflammatory scenario. A better understanding of the relationship occurring across EMTU, environmental noxae, and factors of susceptibility to epithelial damage is likely to pave the way to future new preventive and therapeutic strategies for this condition.

Abstract
BACKGROUND Increased carotid intima-media thickness (cIMT) is considered a marker of early-onset atherosclerosis and it seems to predict cardiovascular events both in obese and diabetic subjects. We aimed to evaluate early signs of atherosclerosis and investigate for predisposing factors in children and adolescents affected by type 1 diabetes (T1DM) or obesity, comparing them with healthy controls. METHODS Out of 71 enrolled subjects (mean age 12.8 ± 2.3 years), 26 had T1DM and 24 were obese, while 21 age- and sex-matched subjects acted as controls. cIMT was measured using standardized methods. Serum glucose, insulin, cholesterol, triglycerides and C-reactive protein levels were evaluated. An oral glucose tolerance test (OGTT) was performed in obese subjects. RESULTS Diabetic and obese individuals showed higher cIMT mean values than healthy controls (p < 0.005). cIMT of the three examined segments correlated positively with fasting glucose levels and negatively with units of insulin/kg/day administered in T1DM individuals. A positive correlation between insulin levels (basal and after oral glucose load) and cIMT of common, internal and external carotid artery was found in obese subjects (p < 0.03). High density cholesterol levels represented a protective factor for cIMT in this latter group of the study population. CONCLUSIONS Our findings show that cIMT correlates with high insulin levels (a sign of insulin resistance) in obese patients and with high fasting glucose levels (a sign of relative insulin deficiency) in T1DM subjects, confirming the need of reducing hyperinsulinism and monitoring blood glucose levels in these subjects to prevent atherosclerosis.

Abstract
The purpose of this study was to test for detectable serum levels of antibodies usually associated with immune-related diseases in children with Vernal keratoconjunctivitis (VKC) and seek for their family history of allergies and autoimmune disorders. The association of human leukocyte antigens (HLA) with VKC was also investigated. We enrolled 181 VKC children and assessed total and specific IgE, antithyroglobulin (AbTG), antithyroidperoxidase (AbTPO), antitransglutaminase (tTG), and antinuclear antibodies (ANA) by standard procedures. Class I and II HLA typing was also carried out following standard protocols, and it was compared with that of healthy subjects. Patients were positive for AbTG (22%), AbTPO (14.6%), and ANA (15.8%), and AbTG positivity was associated with VKC severity (mean ocular score ± SD positive vs. negative: 6.56 ± 2.1 vs. 4.82 ± 2.1; p = 0.03). We found that 12.2% of VKC cases had a positive family history for psoriasis, 6.4% for other cases of VKC, and 5.2% for thyroiditis, while 50.2% of them were atopic. The expression of HLA class I B37 was significantly higher in VKC patients than in controls (7.1% vs. 2.1%, p = 0.04), although not confirmed after multiple antigens testing analysis. Our study suggests a role of common components associated with immune-based diseases in the clinical expression of VKC.

Abstract
We report the case of a patient with an apparent homozygosity for the D1152H mutation located in exon 18 of the cystic fibrosis transmembrane conductance regulator (CFTR) gene. The parents had no personal history of cystic fibrosis (CF) and referred to our laboratory after the diagnosis of fetal bowel hyperechogenicity. The proband presented with meconium ileus and normal sweat chloride test. Sequencing of the CFTR exon 18 together with quantitative genomic assays, such as real-time PCR and the multiplex ligation probe amplification (MLPA) techniques, were performed and revealed that the father was heterozygous for the D1152H mutation and the mother carried a large deletion of the CFTR gene encompassing the genomic sequence including the same mutation. The child inherited D1152H from his father and the large deletion of the CFTR gene from his mother. We suggest that D1152H likely acts as a mild mutation with a dominant effect on the severe deletion of exon 18, considering that after 3 years of clinical examinations the child shows no classical signs and symptoms of CF. Not testing for large deletions in subjects with apparent homozygosity for a mutated CFTR allele could lead to the misidentification of CFTR mutation carrier status.

Abstract
Cystic fibrosis (CF) is caused by CFTR (cystic fibrosis transmembrane conductance regulator) gene mutations. We ascertained five patients with a novel complex CFTR allele, with two mutations, H939R and H949L, inherited in cis in the same exon of CFTR gene, and one different mutation per patient inherited in trans in a wide population of 289 Caucasian CF subjects from South Italy. The genotype-phenotype relationship in patients bearing this complex allele was investigated. The two associated mutations were related to classical severe CF phenotypes.

Abstract
Innate immunity is a pivotal defence system of higher organisms. Based on a limited number of receptors, it is capable of recognizing pathogens and to initiate immune responses. Major components of these innate immunity pathogen recognition receptors are the toll-like receptors (TLRs), a family of 11 in humans. They are all membrane bound and through dimerization and complex downstream signaling, TLRs elicit a variety of specific and profound effects. In recent years, the role of TLRs signaling was not only investigated in infection and inflammation but also in allergy. Fuelled by the hygiene hypothesis, which suggests that allergies develop because of a change in microbial exposure and associated immune signals early in life, it had been speculated that alterations in TLRs signaling could influence allergy development. Thus, TLR genes, genetic variations of these genes, and their association with asthma and other atopic diseases were investigated in recent years. This review provides an overview of TLR genetics in allergic diseases.

Abstract
Asthma is a common inflammatory disease for which the cause is not yet known. Studies of the epidemiology and natural history of childhood asthma into adulthood demonstrate a change in gender prevalence with age. Hormones and inflammation may interact in asthma pathogenesis and determine its course. The same may be true for some endocrine disorders, including diabetes and obesity. Obesity plays a major role in the development of the metabolic syndrome and has been identified as an important risk factor for chronic diseases such as type 2 diabetes mellitus. The prevalence of asthma has paralleled the rise in obesity, suggesting that shared environmental factors could affect both conditions. In addition, endocrine diseases and asthma may share common genetic determinants. In the first part of this review we assess endocrine influences on asthma and overlaps between endocrine disorders and asthma while in the second part we explore the potential benefit of comparative genetic analyses between asthma and endocrine diseases.

Abstract
AIM Corticosteroids and high-concentrated cyclosporine eyedrops have been used for treatment of severe vernal keratoconjunctivitis (VKC) cases. The purpose of our study was to verify the efficacy of 1% topical cyclosporine in improving severe form of VKC in childhood and investigate for factors affecting the response to therapy. METHODS We conducted an open trial involving 197 children with severe VKC, who received topical cyclosporine 1% for four months. Ocular subjective symptoms and objective signs were scored in all children at entry, two weeks and four months. Skin prick tests and microscope endothelial cells evaluation were also performed; serum IgE and cyclosporine levels were assessed. RESULTS The mean score values for severity of subjective symptoms and objective signs were significantly decreased after 2 weeks, and 4 months, compared with those at entry (P<0.001) in all children. Cyclosporine serum levels were not detectable at the end of therapy, nor were endothelial corneal cells damaged. Patients who started the therapy at the beginning of the disease and/or received long-term regimen of treatment with cyclosporine had a faster improvement of ocular signs and symptoms, compared to all other patients. CONCLUSION Our findings suggest that 1% cyclosporine concentration administrated topically at the beginning of the disease and for a long-term period might be the most effective treatment to control symptoms and local inflammation in severe forms of VKC in childhood.

Abstract
BACKGROUND The association of obesity with sleep-associated respiratory disturbances, which has traditionally been described as a problem in adults, actually originates in childhood. We sought an association between sleep-disordered breathing (SDB) and overweight and/or obesity in a large cohort of school- and preschool-aged children in Southern Italy. METHODS One thousand two hundred seven children (612 girls and 595 boys; mean age 7.3 years) were screened by self-administered questionnaires. According to answers, subjects were divided into three groups: nonsnorers (NS), occasional snorers (OS), and habitual snorers (HS). All HS, who also failed an oximetry study at home, underwent polysomnographic monitoring for the definition of SDB. BMI was calculated according to Italian growth charts. RESULTS A total of 809 subjects (67.0%) were eligible for the study. Of them, 44 subjects (5.4%) were classified as HS, 138 (17.0%) as OS, and 627 (77.5%) as NS. Fourteen subjects (1.7%) were given a diagnosis of obstructive sleep apnea syndrome (OSAS). Sixty-four subjects (7.9%) were defined as obese, 121 (14.9%) as overweight, and 624 (77.2%) as normal weight. The frequency of HS was significantly higher in obese subjects than in overweight and normal-weight subjects (12.5% vs 5.8% vs 4.6%, respectively; P = .02), whereas the frequency of OSAS was 1.6% in normal-weight, 1.6% in overweight, and 3.1% in obese subjects (P = not significant). CONCLUSIONS Our findings in a large sample of Italian children suggest that obesity is associated with snoring.

Abstract
Recent studies investigated the role of an unusual immune response to infective agents in the etiology of acute lymphoblastic leukemia (ALL) in children. Human beta-defensin-1 (hBD-1) is an anti-microbial peptide of the innate immune system, which exerts a killing role against pathogens. In the present study, three polymorphisms have been genotyped, namely, -52G/A, -44C/G and -20G/A, of DEFB1 gene, coding for hBD-1, in 40 ALL patients and 40 healthy children, and tested for an association between genetic variants of the protein and seroprevalence of antibodies for herpes viruses. The seroprevalence of cytomegalovirus (CMV), herpes simplex viruses (HSV) and Epstein-Barr virus (EBV) IgG antibodies in leukemic children was higher than that in controls (CMV: 61.5 vs. 27.3%, p = .008; HSV: 50 vs. 24.2%, p = .04; EBV: 61.3 vs. 46.2%, p = ns, respectively). Carriers of the GCA haplotype were found to have a significantly higher rate of immunization against CMV and HSV in ALL children compared to controls (CMV: 68 vs. 29%, p = .006; HSV: 56 vs. 26%, p = .04, respectively). No such observation was made when we analyzed the immunization against Epstein-Barr virus (EBV) by GCA haplotype in case and controls (58 vs. 40%, p = ns). These findings suggest that leukemic patients carrying untranslated variants of hBD-1 display a higher susceptibility to herpes viruses infections than controls.

Abstract
BACKGROUND The therapy for cow's milk proteins allergy (CMPA) consists in eliminating cow's milk proteins (CMP) from the child's diet. Ass's milk (AM) has been recently considered as substitute of CMP. This prospective study investigated tolerance and nutritional adequacy of AM in children with CMPA from Southern Italy. METHODS Thirty children (aged 6 months to 11 years) with suspected CMPA were enrolled. They underwent skin prick tests and bouble-blind, placebo controlled food challenge to CMP. After confirming the diagnosis of CMPA, patients received fresh AM in a open challenge. Specific serum CMP and AM IgE, and biochemical parameters in blood were also assessed. Auxological evaluations were performed in all subjects at entry (T0) and after 4-6 months (T1) of AM intake. RESULTS Twenty-five children resulted elegible for the study, and 24 out of 25 subjects (96%) tolerated AM at the food challenge. Auxological data resulted improved by the end of the study in all patients, while blood biochemical parameters did not vary during the follow-up. CONCLUSION Our data confirm the high rate of AM tolerability in children with moderate symptoms of CMPA. Moreover, we found that AM seems to have nutritional adequacy in subjects with a varied diet.

Abstract
Mannose-binding lectin (MBL) is a C-type soluble collectin involved in the innate immune response. Carriers of MBL gene variant alleles (MBLva) have decreased plasma concentrations of MBL and increased susceptibility to bacterial and viral infections. The aim of the present study is to test the hypothesis that carriers of MBLva could have a different frequency of atopic symptoms as compared to wild-type carriers. A total of 385 consecutively enrolled Caucasian blood donors were studied. Blood specimens underwent genomic analysis and genotyping for MBLva by polymerase chain reaction (PCR). MBLva carrier status was associated with a reduced frequency of allergic rhinitis (OR 0.41 [95% CI 0.2 to 0.8], chi2 = 6.98, p =.008). No relationship was found between MBLva carrier status and asthma or atopic skin symptoms. MBLva might be one of the host-related genetic factors involved in atopic disorders, namely allergic rhinitis.

Abstract
Some studies have proposed exhaled breath condensate (EBC) as a noninvasive tool for monitoring airway inflammation in children. Moreover, atopic dermatitis (AD) has been considered a risk factor for the development of asthma. This study was designed to assess the EBC pH and the exhaled concentration of cytokines produced by T-helper (Th) 1, Th2, and T regulatory cells in asthmatic children and AD and to verify if their concentrations are affected by a short course of treatment with inhaled corticosteroids (ICS). We assessed the mean levels of pH, interferon (IFN) gamma, interleukin (IL)-4, and IL-10 in EBC of children with asthma (n=20) and AD (n=12) and healthy controls (n=20) by enzyme-linked immunosorbent assay (ELISA). Variations of pH and cytokine concentration in response to ICS (flunisolide, 500 microg/day, for 2 weeks), were also investigated in asthmatic patients. We found that the mean condensate pH value in patients with asthma and AD was significantly lower when compared with that of controls (6.9+/-0.2 and 7.0+/-0.2 versus 7.4+/-0.4; p<0.0001) and it significantly increased in asthmatic patients after treatment (7.2+/-0.2 versus 6.9+/-0.2; p=0.003). In addition, the IL-4/IFN-gamma ratio was significantly higher in children with asthma and in those with AD when compared with controls (9.72+/-2.00 and 9.70+/-2.0 versus 8.04+/-2.6; p<0.001) and that it decreased in asthmatic patients after ICS (6.4+/-5.4 versus 9.72+/-2.00; p<0.01). We observed that exhaled IL-10 levels were significantly higher in children with asthma compared with those of controls (18.8+/-8.9 versus 4.2+/-1.0; p<0.002). IL-10 did not significantly increase after treatment with steroids. No such finding was documented in children with AD. Our data suggest that EBC IL-10 levels are different in asthmatic patients compared with healthy children, but they are insensitive markers in monitoring therapy with ICS. Moreover, children with AD show an EBC pH and an exhaled pattern of Th2/Th1 cytokines similar to that of asthmatic patients.

Abstract
Recently, several authors have documented that respiratory infections may cause wheezing and acute exacerbation of asthma in children. Respiratory syncytial virus infections have been recognized to produce the first episode of wheezing in children who go on to develop chronic asthma. Furthermore, repeated infections caused by other common childhood viral pathogens have been proposed to affect responses of the immune system in such a way as to prevent the onset of allergic diseases and possibly asthma. Recently, it became clear that also infections by intracellular pathogens, such as Chlamydia and Mycoplasma, may cause acute and chronic wheezing in some individuals. In this review we describe the immunologic and clinical implications of the association between respiratory infections and asthma.

Abstract
Cyclosporine eyedrops 2% have been used for treatment of corticosteroid-resistant vernal keratoconjunctivitis (VKC) cases. The purpose of our study was to verify the efficacy of 1.25% vs. 1% topical cyclosporine in improving severe form of VKC in childhood. Twenty children with severe VKC, were enrolled in a double-blind, placebo-controlled study and received cyclosporine 1.25% in one eye for 2 wk. Then an open trial was conducted during the next 3 months and 2 wk. Thirty-two more patients were recruited the next year into a new open trial and they received cyclosporine 1% for 4 months. Ocular subjective symptoms and objective signs were scored in all children at entry, 2 wk and 4 months. Skin prick tests and conjunctival scraping tests were also performed; serum immunological and biochemical markers were assessed. The mean score values for severity of subjective symptoms and objective signs were significantly decreased after 2 wk, and 4 months, compared with those at entry (p < 0.001), in both groups of children who received cyclosporine eyedrops 1.25% and 1%, respectively. Serum markers did not differ from the beginning to the end of treatment. Conjunctival eosinophils and cyclosporine serum levels were not detectable at the end of therapy, nor were endothelial corneal cells damaged. Our findings suggest that 1% cyclosporine concentration might be the minimal effective treatment regimen to control symptoms and local inflammation in severe forms of VKC.

Abstract
Recent studies have shown that the pH of exhaled breath condensate (EBC) could be predictive of asthma exacerbation. Moreover, it has been documented that both allergic rhinitis and atopic dermatitis constitute risk factors for the occurrence of asthma in a progression of disease known as atopic march. The aim of our study was to establish if condensate pH could be used as a valuable mean of monitoring of asthma in atopic children. We studied 34 atopic children with acute asthma, 70 with stable asthma, 35 children with allergic rhinitis, and 17 with atopic dermatitis. Thirty healthy children were used as controls. All children underwent skin prick tests and lung function tests. Exhaled breath condensate samples were collected with a condensing device and de-aerated with argon. The pH of EBC was measured using a pH meter. Children with acute asthma were treated with inhaled steroids and bronchodilators. We found that the pH of condensate in patients with acute asthma was lower than that of patients with stable asthma, rhinitis, and controls (7.25 vs. 7.32, p < 0.05; 7.25 vs. 7.48, p < 0.02; 7.25 vs. 7.78, p < 0.0001, respectively). Patients with stable asthma, rhinitis, and eczema had also lower pH than that of controls (7.32, 7.48, and 7.44 vs. 7.78; p < 0.0001, p < 0.006, p < 0.04, respectively). Patients with acute asthma normalized their pH after treatment (7.82 vs. 7.25; p < 0.0001). Finally, patients with acute asthma showed a positive correlation between pH and lung functional parameters (forced expiratory volume in 1 s; r = 0.39, p = 0.04). Our study shows that EBC pH measurement may be a promising marker for assessing airway inflammation and monitoring response to anti-inflammatory treatment in asthmatic children. Furthermore, we report the first evidence of airways acidification in children with allergic rhinitis and atopic dermatitis. Therefore, EBC pH assessment may be useful in the evaluation of progression of the atopic march toward the development of asthma later in life. Further studies are recommended in order to confirm this indication.

Abstract
Sjögren's syndrome (SjS) is an autoimmune disease characterized by distraction of particularly salivary and lacrimal glands. The aim of the present study was to compare salivary gland scintigraphy (SGS) and salivary gland ultrasonography (SUS) in identifying salivary gland function in patients first diagnosed with SjS. We recruited 20 such patients with SjS (5 male, 15 female, aged from 35 to 65 y, mean age 52, standard deviation: +/-5 y. All patients were submitted to SUS and SGS longitudinal and transverse images. Before the scintiscan, patients fasted for 6 h. Technetium-99m pertechnetate ((99m)Tc-PT) 110 MBq was injected intravenously (i.v.) and simultaneous multi-frames dynamic acquisition was performed for 30 min. In two patients who had discordant results between SUS and US, labial biopsy was performed. Dynamic acquisition curves for 30 sec for the parotid and the submandibular glands were generated. For each gland we have calculated: (a) the maximum uptake (MU): the ratio between the mean counts in the gland at 20 min and the background activity and (b) the outflow efficiency (OE): the ratio between the minimum counts after lemon juice stimulation at 30 min and the counts at 20 min. The results showed abnormal scintiscans with low MU and high OE in one or more of the glands, in 17/20 patients. These results were confirmed by SUS in 15 cases and in two cases labial biopsy confirmed the diagnosis made by SGS while SUS was negative. In the remaining 3/20 cases of SjS both tests, SUS and SGS, showed normal results. Discrepancies between SGS findings and labial biopsy as found in two of our cases have been reported by others and may be due among other causes to early lymphocytic infiltration in SjS. Normal findings of SGS have also been reported. In conclusion, in cases first diagnosed with SjS, the function of the parotid and the submandibular glands was better identified by the SGS as compared to SUS. Although SGS is a more complex and expensive examination, it should be preferred to SUS as more sensitive and indicating the stage of SjS.

Abstract
BACKGROUND Atopic eczema/dermatitis syndrome (AEDS) is a chronic inflammatory skin disease, affecting 10-20% of children and 1-3% of adults. The purpose of this pilot study was to assess the clinical and anti-inflammatory effect of bacterial and ribosomal immunotherapy with Immucytal (Pierre Fabre Médicament, France) in children with AEDS. METHODS Seventeen children with allergic and non-allergic forms of AEDS (AAEDS and NAAEDS, respectively), graded moderate to severe (Severity Scoring of Atopic Dermatitis [SCORAD] index of >25), received ribosomal immunotherapy (Immucytal) once daily according to the standard treatment regimen (4 consecutive days a week for 3 weeks, and then 4 consecutive days a month for 4 months). We assessed the clinical status of AEDS using the SCORAD index at baseline, and after 8 and 20 weeks of treatment. Furthermore, peripheral blood from patients was examined for the frequencies of CD4+ cells expressing interferon (IFN)-gamma and interleukin (IL)-4 using flow cytometry. RESULTS There was a progressive and significant clinical improvement of AEDS, confirmed by a reduction of the SCORAD index over time in both AEDS forms (p < 0.01). Pooled data from the two groups showed that the mean baseline index of 43 was reduced to 17 after treatment. Overall, these data indicate a marked improvement in total clinical severity of AEDS (-62%). Flow cytometry analysis showed that frequencies of the two CD4+ T cell subsets did not differ significantly from the beginning to the end of the study in both forms of AEDS. However, the percentage of CD4+ cells expressing IL-4 in children with AAEDS tended to decrease by the end of treatment with ribosomal immunotherapy. Clinical and laboratory data confirmed that immunotherapy was well tolerated. CONCLUSIONS The results of this pilot investigation suggest that ribosomal immunotherapy may be beneficial in the management of AEDS in children, and that this could be at least partially explained by a role in restoring the type 2 helper-T cell imbalance seen in allergic patients. Placebo-controlled, randomized clinical trials are recommended in order to confirm these findings.
