Abstract
BACKGROUND Asthma is the most common chronic disease in children and a robust diagnosis is crucial to optimize patient care and reduce its burden. To diagnose asthma in children, the Global Initiative for Asthma (GINA) recommendations propose a 12% improvement in forced expiratory volume in 1 second (FEV1) after a bronchodilation test. Nevertheless, such a criterion is rarely confirmed in these patients in clinical practice. OBJECTIVE The objective of this study was to evaluate the sensitivity of spirometric and clinical parameters in identifying children with possible asthma. METHODS The VERI-VEMS Study is a multicenter international retrospective cohort study. Data were collected, from January 2008 until January 2019, for all consecutive children (aged 5-18 years), with a diagnosis of asthma, who performed a spirometry at the time of the diagnosis. We compared the sensitivity of the reversibility criterion proposed by GINA guidelines, with other spirometric and clinical variables, using physician-diagnosed asthma and response to treatment as the standard. RESULTS The study included 871 children. The reversibility criterion of 12% of FEV1 showed a sensitivity of 30.4%. The 3 best spirometric or clinical criteria were the presence of dry cough, or wheezing or atopy and dry cough, or wheezing or exercise-induced dyspnea, with a sensitivity reaching 99.5%, with no added value of the spirometric parameters in the calculation of the cumulated sensitivity for the diagnosis of pediatric asthma. CONCLUSIONS Postbronchodilator reversibility of 12%, although essential for patients' follow-up, has an insufficient low sensitivity in reaching a diagnosis of asthma in pediatric patients, compared with a combination of clinical symptoms, that show a better sensitivity. Further studies on specificity will help clarify the role of this change in the diagnostic paradigm in formally diagnosing children with asthma.

Abstract
INTRODUCTION Allergic rhinitis is a worldwide health problem, currently affecting up to 40% of the general population, and characterized by the following symptoms in a variable degree of severity and duration: nasal congestion/obstruction, rhinorrhea, itchy nose and/or eyes, and/or sneezing. General symptoms like fatigue, reduced quality of sleep, impaired concentration and reduced productivity, if left untreated, may significantly affect quality of life. In addition, of being associated to various comorbidities, allergic rhinitis is also an independent risk factor for the development and worsening of asthma. Perennial allergic rhinitis is caused by allergens present around the year. AREAS COVERED Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines currently recommend a stepwise therapeutic approach that combines patient education with specific allergen avoidance, symptomatic pharmacotherapy and allergen immunotherapy. The available treatment strategies provide suboptimal symptom relief in patients with moderate-to-severe disease who continue to experience symptoms while treated, even on multiple therapies. EXPERT OPINION New insights into current therapy have been provided with the development of new symptomatic drugs with improved pharmacokinetics and safety. However, the ultimate research goal is beyond symptomatic treatment, and is mainly directed at modifying the immune response to allergens and prevent the progression of allergic rhinitis towards asthma. In this direction, promising advances are expected in the fields of allergen immunotherapy and biological drugs, such as omalizumab. Finally, significant research efforts are also focused on the growing number of new specific molecular targets involved in the Th2 pathway inflammation of allergic diseases.

Abstract
INTRODUCTION The evolution in immunological methods used to assess human allergic diseases has led to the identification of immunoglobulin E (IgE) as a diagnostic biomarker and a potential therapeutic target. Innovative technologies in molecular biology and immunogenetics contributed to the development of a selective blocking agent, disclosing new therapeutic perspectives in the treatment of allergic asthma. Omalizumab is the most advanced humanized anti-IgE monoclonal antibody that specifically binds serum-free IgE. Omalizumab also interrupts the allergic cascade by preventing binding of IgE with FcεRI receptors on mast cells, basophils, antigen-presenting cells and other inflammatory cells. AREAS COVERED This review discusses the discovery strategy and preclinical development of omalizumab. Furthermore, it also provides a clinical overview of the key trials leading to its launch and a detailed analysis of safety and post-marketing data. EXPERT OPINION The clinical efficacy of omalizumab in allergic asthma has been well documented in clinical trials, involving adults, adolescents and children with moderate-to-severe and severe allergic asthma. To date, omalizumab has also been approved in chronic idiopathic urticaria for patients 12 years and older who remain symptomatic despite high dosages of H1 antihistamines. Omalizumab has also been investigated in many other different patient populations beyond allergic asthma and may yet have an application to other indications. While omalizumab is the only mAb available for treating allergic asthma, the authors anticipate that new mAbs will emerge in the future that overcome omalizumab's current limitations.

Abstract
Background A non-steroidal, anti-inflammatory moisturizing cream containing rhamnosoft, ceramides, and L-isoleucine (ILE) (pro-AMP cream) has been recently developed for the specific treatment of atopic eczema (AE) of the face. In this trial, we evaluated the clinical efficacy and tolerability of pro-AMP cream in the treatment of facial AE in children in comparison with an emollient cream. Methods In a randomized, prospective, assessor-blinded, parallel groups (2:1) controlled trial, 107 children (72 allocated to pro-AMP cream and 35 allocated to control group) with mild-to-moderate chronic AE of the face were enrolled. Treatments were applied twice daily for a 6-week period. Facial Eczema Severity Score (ESS) was evaluated at baseline, week 3, and week 6, by an assessor unaware of treatment allocation. Investigator's Global Assessment (IGA) score was assessed at week 3 and at week 6. Tolerability was evaluated at week 3 and at week 6 using a 4-point score (from 0: low tolerability to 3: very good tolerability). Results At baseline ESS, mean (SD) was 6.1 (2.4) in the pro-AMP cream group and 5.3 (3) in the control group. In the pro-AMP group, in comparison with baseline, ESS was significantly reduced to 2.5 (−59%) after 3 wks and to 1.0 (−84%) at week 6 (p = 0.0001). In the control group, ESS was reduced to 3 (−42%) at week 2 and to 2.6 (−50%) at week 6. At week 6, ESS in pro-AMP cream was significantly lower than the control group (1.0 vs. 2.6; p = 0.001). Both products were well tolerated. Conclusion Pro-AMP cream has shown to be effective in the treatment of mild-to-moderate chronic lesion of AE of the face. Clinical efficacy was greater in comparison with an emollient cream. (Clinical trial Registry: NTR4084).

Abstract
Atopic dermatitis (AD) is a common allergic disorder and may be associated with respiratory allergy. In this study serum levels of IgE specific for the major allergen of birch (Bet v 1) were measured in two groups of AD patients with specific IgE to birch: the first with associated respiratory birch allergy and the second with cutaneous symptoms alone. The results show that the patients suffering from AD associated with respiratory allergy had the highest serum levels of IgE specific for Bet v 1. In conclusion, this study shows that the measurement of serum specific IgE for a major allergen may be useful in common practice as high levels are associated with complicated pathology.

Abstract
Serum neopterin may be considered a diagnostic marker of the degree of activation of the immune system. This preliminary study was performed to measure serum neopterin levels in patients with acute spontaneous urticaria (ASU), chronic spontaneous urticaria (CSU) and atopic dermatitis (AD). In total, 180 patients [96 men, 84 women; mean age 23.1 years; 41 with spontaneous urticaria (13 ASU and 28 CSU), 48 with AD] and 96 healthy controls were enrolled in the study. Patients with ASU had the highest neopterin levels, and all three groups of patients (ASU, CSU and AD) had higher values than normal subjects. This preliminary study demonstrates that serum neopterin could be a biomarker of immune activation in patients with SU or AD.

Abstract
Allergic rhinitis (AR) is characterized by Th2 polarized immune response, such as increased IL-4 and reduced IFN-γ production, and by a functional defect of T regulatory cells. This impaired immune response profile influences the pattern of immunoglobulin (Ig) production in allergic patients. However, no studies have compared the pattern of inhalant allergen-specific Ig classes between allergic patients and normal subjects. The aim of this study is to therefore investigate the allergen-specific IgE, IgG, IgG4, and IgA serum level pattern in a group of patients with pollen allergy and in non-allergic healthy subjects. One hundred and two allergic patients (evaluated both out of and in the pollen season) were enrolled. In addition, 50 healthy non-allergic subjects were recruited during the whole year. Serum allergen-specific IgE, IgG, IgG4, and IgA for Parietaria, grasses, and birch were quantitatively determined by the ImmunoCAP System method. Allergen-specific IgE, IgG, IgG4, and IgA serum levels were significantly different for each tested allergen (p=0.0001 for each class) among groups. Allergic patients, mainly during pollen season, showed the highest IgG, IgG4, and IgA levels. The present study therefore provides the preliminary evidence that Ig production pattern toward inhalant allergens may depend on the specificity of the allergenic response both in non-allergic subjects and allergic patients Allergic patients do not show a defect of IgG and IgA classes. In addition, this study is the first that quantitatively evaluates the Ig classes. However, further studies should include non-allergic subjects evaluated both during and out of the pollen season.

Abstract
Allergic rhinitis (AR) and asthma are characterized by Th2 polarized immune response. Soluble HLA (sHLA) molecules play an immunomodulatory activity. It has been reported that both molecules are increased in sera of patients with pollen-induced allergic rhinitis studied outside the pollen season. To date, however, no study has investigated them in AR children. The aim of this preliminary study is to evaluate serum sHLA-G levels in children with AR or asthma patients and in a group of healthy controls. Forty-seven symptomatic allergic patients were enrolled. A group of 50 healthy subjects was considered as control. Serum sHLA-G levels were determined by the immunoenzymatic method. Children with AR had significantly higher levels of sHLA-G molecules than normal controls or children with allergic asthma. However, there is no difference between children with AR and asthmatics. In conclusion, the present study provides the preliminary evidence that serum sHLA-G molecules are significantly increased in children with AR.

Abstract
Allergic rhinitis (AR) is characterized by a Th2 polarized immune response, and specific immunotherapy modifies this arrangement, restoring a physiologic Th1 profile. Sublingual immunotherapy (SLIT) is widely prescribed. The aim of the study is to evaluate two different methods for assessing IFN-γ, namely ELISPOT and ELISA, before and after a pre-seasonal SLIT course as marker for Th1 response. Thirty-eight AR patients with pollen allergy assumed pre-seasonal SLIT for 3 months. Patients' blood samples for assessing IFN-γ serum levels were collected before initiating SLIT (baseline – T0), after 3 months pre-seasonal SLIT course (T1), and three months after completion of SLIT (T2). IFN-γ-specific producing cells, after allergen stimulation, were assessed by cytokine ELISPOT at the same time points. IFN-γ-specific producing cells significantly increased after SLIT both at T1 and T2 (p=0.0002). On the contrary, ELISA assessment did not reveal an increase in IFN-γ serum levels at any time point. In conclusion, these results demonstrate that ELISA assessment of serum IFN-γ is not suitable for identifying an early response.

Abstract
Th17 is a subset of T helper lymphocytes and exerts pro-inflammatory activities. Recently, it has been reported that serum IL-17 levels are high in the most severe patients with birch allergy studied both outside and during the pollen season. This study aims to compare the frequency of peripheral IL-17-producing T cells in children with allergic rhinitis and in healthy controls. Ten children with allergic rhinitis and 5 healthy non-allergic subjects were evaluated. Th17 were evaluated by intracellular staining in ex-vivo T cell compartment. Ex- vivo PBMNC evaluation showed that allergic patients had higher frequencies of IL-17 producing T cells, both concerning CD4+ and CD8+ cells. In particular, there is a subset co-expressing IL-17 and IFN-gamma both for CD4+ and CD8+ cells. In conclusion, this preliminary study suggests a possible role of Th-17 cells in the response to allergens in children.

Allergic rhinitis (AR) may be frequently associated with or precede asthma. Bronchial involvement in AR is usually detected by spirometry, however, spirometers are rarely available. The aim of this study is to verify the suitability of the use of visual analogue scales (VAS) as a surrogate for screening spirometry in assessing respiration in AR patients. One hundred twenty patients with allergic rhinitis were studied. VAS for respiration assessment and spirometry were performed in all patients. There was a significant, though weak, relationship between VAS assessment of respiration and FEV(1) (p=0.0076; r=0.244). In conclusion, this preliminary study suggests the use of VAS as screening to assess the respiration of patients with allergic rhinitis who may be candidates for spirometry.

Abstract
BACKGROUND T helper (Th)-17 cells are a subset of T helper lymphocytes that exert regulatory activities. Recently, it has been reported that serum interleukin (IL)-17 levels are high in the most severe cases of birch allergy studied outside the pollen season. OBJECTIVE The aim of this study was to investigate a possible relationship between serum IL-17 levels and clinical parameters in patients with allergic rhinitis studied during the pollen season. METHODS In all, 56 patients with persistent pollen-induced allergic rhinitis were evaluated during the pollen season. Serum IL-17 levels were evaluated by enzyme-linked immunosorbent assay. Symptoms were assessed by visual analogue scale, drug use was monitored and peripheral eosinophils were counted. RESULTS Serum IL-17 levels were significantly related to clinical symptoms, drug use and peripheral eosinophil counts (P = 0.0001 for all). CONCLUSION This study provides evidence that serum IL-17 level assessment might be considered to classify allergy severity.

Abstract
Recently, it has been reported that IL-17 may be involved in allergic reaction. Sublingual immunotherapy (SLIT) is the unique curative treatment for allergic rhinitis. This study aims at investigating whether one course of birch SLIT could affect serum IL-17 levels. The findings provided show that some IL-17 producer patients had a reduction of serum IL-17 levels after one SLIT course. Therefore, this preliminary study shows that a single pre-seasonal SLIT course may induce a significant decreasing trend in serum IL-17 levels; further study should be carried out to define the role exerted by IL-17 in allergic rhinitis.

Abstract
The IgG response to allergens is well-known, however few studies have investigated IgG and IgG4 production in normal subjects. Therefore, total IgG and IgG4 serum levels specific for 6 common inhalant allergens were measured in 282 non-allergic subjects to establish reference values at different ages and sex. Thus, 282 subjects were studied (141 female and 141 male) ranging from pre-school to adult age, all living in Northern Italy at the time of the study. Family history of first degree relatives and personal history were negative for allergic diseases. The findings obtained in this study indicate that: i) reference values for specific IgG4 and IgG levels against the allergen studied should take into account both the sex and age of the subject evaluated; ii) there is a difference in trend for age between seasonal and perennial allergens and iii) the relationships between age and specific IgG4 and IgG levels have different slopes. In conclusion, relevant differences exist in the distribution of IgG and IgG4 levels in normal subjects.

Abstract
In order to evaluate the infectious agents associated with the first episode of severe acute wheezing in otherwise healthy infants and to define the role of each of them in recurrences, 85 patients in Italy, aged <12 months, hospitalized because of a first acute episode of wheezing, were prospectively enrolled between 1 October 2005 and 31 March 2006. Upon enrollment, nasopharyngeal swabs were collected for the real-time PCR detection of respiratory syncytial virus (RSV) types A and B, influenza virus types A and B, adenovirus, parainfluenza viruses types 1, 2, 3 and 4, rhinovirus, human metapneumovirus, human coronavirus types 229E, OC43, NL63, and HKU1, bocavirus, enterovirus, and paraechovirus; nasopharyngeal aspirates were also obtained to detect atypical bacteria. At least one infectious agent was identified in 76 children (89.4%). RSV was the most frequently detected pathogen and its prevalence was significantly higher than that of the other pathogens in both age groups, and significantly higher in the children aged 3-12 months than in those aged <3 months. Only the children with RSV infection experienced recurrent wheezing. Viral load was significantly higher in children with than in those without recurrent wheezing. This study shows that RSV is the main reason for hospitalization during the first wheezing episode in infants, and that it appears to be the only pathogen associated with a high frequency of recurrences. A high viral load seems to be strictly related to the likelihood of recurrence.

Abstract
Allergic rhinitis (AR) is characterized by a Th2 polarized immune response. Specific Immunotherapy modifies this bias restoring a physiologic Th1 profile. Sublingual immunotherapy (SLIT) is widely prescribed, but there is no early, simple marker of response. This study was undertaken in order to determine whether serum IL-4 might be a possible marker of SLIT immunological response in order to quickly and easily detect responder patients. Thirty-nine AR patients with a pollen allergy assumed preseasonal SLIT for 3 months. VAS for symptoms and medication efficacy were evaluated. Serum IL-4 was assessed before and 3 and 6 months after SLIT initiation. Eighty-two percent of patients (32/39) showed a clinical response to SLIT. Serum IL-4 significantly decreased at 6 months post-therapy in responders, whereas it increased in non-responders. In conclusion, these results may be considered clinically relevant proof that SLIT treatment induces a quick reduction in Th2 polarization. Serum IL-4 appears to be an early marker of immunological response to SLIT.

Abstract
BACKGROUND Allergic disorders are characterized by type 2 helper T cell (Th2)-polarization, thus physiological type 1 helper T cell (Th1)-dependent mechanisms involved in fighting respiratory infections (RI) may be defective. It has previously been reported that allergic children have more numerous and severe RI than nonallergic ones. OBJECTIVE The aim of the study was to evaluate the number and duration of RI in adult allergic and nonallergic subjects. METHODS Six hundred and twenty-four subjects were studied; 202 of them were allergic (i.e. suffering from allergic rhinitis). The number of RI as well as the duration of the disease were recorded for 2 years. RESULTS Allergic subjects showed a significantly higher rate of RI episodes [adjusted incidence rate ratio (IRR) = 2.16, 95% confidence interval (CI) 1.94-2.41, P < 0.001] than subjects without allergy. The number of mild RI episodes was slightly higher in allergic subjects (IRR = 1.68, 95% CI 1.50-1.89, P < 0.001), while the number of severe episodes was markedly higher (IRR = 15.71, 95% CI 10.35-23.84, P < 0.001) when compared with nonallergic subjects. Moreover, allergic patients showed a longer total duration of RI than nonallergic subjects, with a mean difference of 17.4 days (95% CI 15.5-19.4, P < 0.001). CONCLUSIONS This study provides evidence that adult allergic patients have more numerous and prolonged RI than nonallergic subjects.

Abstract
Pesticide use still now is a remarkable risk for all cultivation operators, including farmers and flower-growing workers. Recently, pesticides use on ornamental plant has been demonstrated to be able to determine a risk extension to general population. Aim of the project was to elaborate and to apply a method for pesticides risk evaluation in ornamental plant cultivations, as to define workers exposure and its possible diffusion to not occupationally exposed populations. Main features of method will be sampling and analysis approach. The first will estimate air dispersion of pesticides in garden centre, skin and garment smarminess in nurserymen and leaf adhered amounts, in concomitance with treatment and periodically to estimate natural decay. The latter will characterize pesticides by means of different methods (liquid and gaseous chromatography, spectrophotometry and spectrometry). Final aim will also be to identify the most reliable analytic method, as concerns accuracy, sensitivity and specificity.

Abstract
The efficacy and safety of sublingual immunotherapy (SLIT) are currently supported by clinical trials, meta-analysis and post-marketing surveys. Practice parameters for clinical use of SLIT are proposed here by a panel of Italian specialists, with reference to evidence based criteria. Indications to SLIT include allergic rhinoconjunctivitis, asthma, and isolated conjunctivitis (strength of recommendation: grade A). As to severity of the disease, SLIT is indicated in moderate/severe intermittent rhinitis, persistent rhinitis and mild to moderate asthma (grade D). SLIT may be safely prescribed also in children aged three to five years (grade B), and its use in subjects aged more than 60 years is not prevented when the indications and contraindication are ascertained (grade D). The choice of the allergen to be employed for SLIT should be made in accordance with the combination of clinical history and results of skin prick tests (grade D). Polysensitisation, i.e. the occurrence of multiple positive response does not exclude SLIT, which may be done with the clinically most important allergens (grade D). As to practical administration, co-seasonal, pre co-seasonal, and continuous schedules are available, being the latter recommended for perennial allergens or for pollens with particularly prolonged pollination, such as Parietaria (grade D). For pollens with relatively short pollination, such as grasses and trees (cypress, birch, alder, hazelnut, olive) the pre co-seasonal and perennial schedules are preferred (grade C). The build-up phases suggested by manufacturers can be safely used (grade A), but they can be modified according to the patient's tolerance (grade C). A duration of SLIT of 3-5 years is recommended to ensure a long-lasting clinical effect after the treatment has been terminated (grade C).

Abstract
BACKGROUND Recently, it has been evidenced that the forced expiratory flow at the 25 and 75% of the pulmonary volume (FEF25-75) might be considered as a possible marker of early bronchial impairment in patients with allergic rhinitis alone. OBJECTIVES The aim of this study was to determine whether a spirometric impairment may predict allergy during screening visit. METHODS The study included 283 Navy soldiers (255 males, mean age 27.1 + 8.2) who had to undergo spirometry for attending specific courses. Fifty-four showed slight spirometric anomalies. Thus, they referred to Navy Hospital of La Spezia for standardized tests: skin prick test, spirometry, and methacholine bronchial challenge. RESULTS Forty seven (87%) subjects were sensitized (47% monosensitized and 53% polysensitized). Allergic rhinitis was diagnosed in 25 subjects with median nasal TSS 5. FVC and FEV1 values were normal, whereas FEF25-75 values were reduced (61.8 + 14.8 % of predicted), bronchodilation test was significant for FEF25-75 (82.9 + 16.8% of predicted; p<0.001) only. Bronchial hyperreactivity (BHR) was detected in 28 subjects, all but 1 were sensitized. CONCLUSIONS This study provides evidence, relevant to clinical care, that mild spirometric impairment may generate the suspect of allergic disorders, thus spirometry could be more frequently performed in general population screening.

Abstract
BACKGROUND The Link between allergic rhinitis and asthma is well known. Bronchial hyperreactivity (BHR) may be present in rhinitics. The present study is aimed at evaluating a large group of subjects suffering from allergic rhinitis alone to investigate the presence of spirometric impairment and BHR both during and outside the pollen season. METHODS 360 rhinitics (subdivided in 3 groups: seasonal, SAR, perennial, PAR, and polysensitized, PolysR) were investigated by spirometry and methacholine challenge. RESULTS There was a significant seasonal difference concerning the number of rhinitics with impaired FEV1 (p<0.01 for SAR, p<0.02 for PAR, and p<0.03 for PolysR) and FEF25-75 (p<0.05 for SAR, p<0.03 for PAR, and p<0.05 for PolysR) as well as with BHR (p<0.05 for SAR and p<0.03 for PAR). CONCLUSIONS This study evidences that an impairment of spirometric parameters and BHR may be observed in patients with allergic rhinitis alone. Thus, careful evaluation of lower airways should be performed in patients with allergic rhinitis alone.

Abstract
BACKGROUND Subcutaneous specific immunotherapy has been demonstrated capable of inducing T regulatory response. There is few evidence concerning immunological changes induced by sublingual immunotherapy. OBJECTIVE The aim of this study was to evaluate T cell proliferation in subjects successfully treated with SLIT for HDM. METHODS PBMCs were isolated from patients after at least 3 years of successful HDM SLIT and from matched untreated allergic and healthy control subjects. After 3 and 6 days of in vitro stimulation with PHA, Candida albicans, Dermatophagoides farinae, grasses, Parietaria judaica, and cat, proliferation. RESULTS Subjects treated with SLIT showed significant reduction of proliferation induced by Candida albicans, Parietaria, and grasses in comparison with untreated atopics (p=0.0002, 0.0033, and 0.009 respectively). CONCLUSION This pilot study confirms reduced T cell proliferation in allergic subjects treated with SLIT.

Abstract
The aim of the present study was to evaluate the persistence of anti-hepatitis B protective levels in young patients with type 1 diabetes, successfully immunised with a recombinant hepatitis B vaccine. We re-evaluated, after a 4 year follow-up, 54 patients and 70 age and sex-matched healthy subjects. Protective antibodies levels were found in 50/54 (92%) patients and in 67/70 (96%) controls. Moreover, anti-HBs levels were similar in diabetic patients and controls (means of log-titre and (sd); 1.95 (0.88) and 2.18 (0.64) patients and controls, respectively; P=0.11). No cases of clinical hepatitis were reported and all patients and controls remained HBc negative. These data demonstrate the persistence of anti-HBs levels in children, adolescents and young patients with type 1 diabetes after recombinant hepatitis B vaccine showing evidence of longterm immunogenity and protective effect.

Abstract
The phenotype and functions of T lymphocytes and of natural killer (NK) cells have been investigated in four children and five adults from three Italian families infected with HIV (LAV/HTLV III). The results show a heterogeneous pattern of immunological derangements involving distribution of T and natural killer subsets, proliferation in response to T cell mitogens and natural killer activity. However, all infected patients tested showed a very low or absent phytohaemagglutinin induced interleukin-2 production regardless of age and clinical conditions, while concanavalin A-induced interleukin-2 production was within the normal range. The impaired interleukin-2 production in response to phytohaemagglutinin in some patients is not related to phytohaemagglutinin-induced proliferation, to clinical conditions or to a defective distribution of T cell subsets. These results suggest that, in our patients, both adults and children, HIV (LAV/HTLV III) has an "early" tropism for a subset of T cells involved in interleukin-2 production.

Abstract
The characteristics of acquired immunodeficiency syndrome (AIDS) in children have been described in several reports. The occurrence of specific anti-HTLV-III/LAV seropositivity in children born to seropositive mothers is also becoming more frequent in Italy. We report 15 cases of seropositive children born to 14 seropositive, drug-addicted mothers. Among them, 5 died of AIDS, 8 developed a variable, non-progressive AIDS-related complex (ARC), while only two remained persistently asymptomatic. Liver disease was present in 2 patients, CNS disease in 4, gastrointestinal troubles were never a major problem. Only 2 cases of HBV infection and 3 of thrombocytopenia were observed. In our experience, homosexual behaviour of the parents was never a cause of family risk. Children presented with failure to thrive and/or signs of disease usually within the first five months of life. In one family the first child was affected by fatal AIDS while the younger child showed only passive, transient immunization by maternal specific IgG. One ARC patient, observed for over 3 years, showed apparently complete healing from the disease.

Abstract
Immunological functions were studied in two 22-month-old dizygotic twins with the characteristic features of Shwachman syndrome. A severe defect of neutrophil motility was found in both children, but not in their parents. An impairment of the activity of the alternative pathway of complement was present in the sera of both patients. This defect, in association with the neutropenia and the chemotactic defect, might be related to the recurrent infections displayed by the twins.

Abstract
The inhibitory effect of neutrophil chemotaxis of gentamicin, tobramycin, and sisomicin was shown. The combined effect of aminoglycosides and histamine was not additive.
