Abstract
OBJECTIVE To specify clinical and immunological parameters of the mechanisms, which may lead to development of persistent asthma, or regression of the disease symptoms. METHODS Eighty children with childhood asthma, diagnosed in the past by using the modified Asthma Predicted Index (mAPI), were divided into two groups: remission group and persistent group. There were 3 study visits (baseline, at 6 mo, and at 12 mo). Clinical remission of asthma was defined as the absence of asthma symptoms for at least 12 mo without treatment. The patients could switch from one group to another during the 12 mo of follow-up. Clinical, inflammatory, and immunoregulatory predictors of asthma remission/persistence were analyzed. RESULTS The presence of mAPI criteria as well as house dust mite (HDM) allergy and allergic rhinitis at 7-10 y, were associated with a reduced prevalence of asthma remission. The increased eosinophil blood count in mAPI criteria was associated with a lower expression of CD25 positive cells. HDM allergy was associated with a higher fractional exhaled nitric oxide (FeNO) level (p = 0.0061) and higher expression of CD25CD71 (p = 0.0232). Allergic rhinitis was associated with a higher expression of PPAR (p = 0.0493) and CD25CD71 (p = 0.0198), and lower expression of glycoprotein A repetitions predominant (GARP). CONCLUSIONS Persistence of childhood asthma was largely determined by the presence of allergic rhinitis and sensitization to HDM. Additionally, API criteria but not immunoregulation processes, were related to asthma persistence.

Abstract
Background Cystic Fibrosis newborn screening (CFNBS) is the optimal method to diagnose the disease during the asymptomatic period. The aim of the study was to determine how CFNBS affects long term clinical outcomes. Methods Data from infants who were born in Lodz Voivodship, referred to CF center as a part of CFNBS according to IRT/DNA protocol were compared to the data of children with established CF diagnosis before the start of NBS in Poland (Group CF, n = 52). Results In 37 children (during 151 referred infants) the diagnosis of CF was established due to CF NBS (CF NBS Group, n = 37). The average time of diagnosis was 1.59 month in Group CF NBS and 45.25 months in 52 children from Group CF. Pulmonary exacerbations occurred on average 4.2 times in Group CFNBS and they were hospitalized on average 0.5 times compared to Group CF – respectively 6.77 and 2.14 (p < 0.001). The number of PA infected patients increased between the fifth and eighth year of age (OR = 1.16 (95% CI: 1.04–19) (P = 0.007)) regardless of the study group (P = 0.984). Patients with MRSA infection have a higher risk of PA infections in subsequent years of their life (OR = 1.45 (95% CI: 1.03–2.03) (P = 0.032)). Conclusions CF NBS has beneficial effects primarily on decrease of pulmonary withhope for a longer life expectancy and better and centralised treatment in multidisciplinary CF focused centres.

Abstract
BACKGROUND Several studies suggest that early-life exposure to animal allergens constitutes a relevant risk factor for the development of allergic sensitization. OBJECTIVES The aim of the present study was to determine the role of interleukin-33 in children sensitive to cat allergen with allergic rhinitis and/or asthma. METHODS The study included 51 children aged 5-18 years, both sexes, allergic to cats. Sensitization to cat allergen was confirmed by skin prick tests or specific IgE. Children were evaluated for the presence of bronchial asthma, atopic dermatitis, allergic rhinitis. A questionnaire evaluating the occurrence of allergic symptoms in children after contact with the cat and dog was performed. Mothers completed a questionnaire regarding cat exposure: during pregnancy and having a cat at home. A blood sample was taken from all children to measure the level of IL-33 in the serum. RESULTS Keeping a cat in the home, once in the past, or having a cat in the home during the mother's pregnancy, revealed a statistically significant relationship with IL-33 levels in the studied patients. Also, daily contact with a cat during pregnancy affected the level of IL-33. Higher levels of IL-33 were shown in people with hypersensitivity to cat and pollen allergens and cat and other animals. In patients with bronchial asthma higher levels of IL-33 were found than in patients without bronchial asthma. CONCLUSIONS Increased serum levels of IL-33 is related with keeping cats during pregnancy and in early childhood and can be associated with the development of asthma in children.

Abstract
Background: This study was based on data from the Polish Mother and Child Cohort Study. Objective: The aim was to study associations between home environment factors and allergic diseases at 1 year of life and new onset and remission of children's allergy diagnosis at ages 7-9 years. Methods: Children's health status was assessed at ∼12 months of age and then at ages between 7-9 years by using a questionnaire administered to the mothers. Children were assessed by pediatrician/allergists. The patients, who were 7-9 years old, underwent skin-prick tests. Exposure to tobacco smoke was evaluated with a questionnaire addressed to parents and/or caregivers and cotinine measurements were taken of mother's saliva during pregnancy and in children's urine at ages 7-9 years. Incidence and remission were calculated by comparing symptoms in the first year of life with symptoms at 7-9 years. We studied the associations among demographic data, home environment, and new onset and remission of food allergy, atopic dermatitis, and asthma and allergic rhinitis in logistic regression analysis. All associations were adjusted for independent risk factors of dependent variables. Results: Data from 211 participants were included in the analysis. During the first year of life, food allergy was the most common symptom (39%), followed by atopic dermatitis (35%) and asthma (12%). When comparing diagnoses at ages 7-9 years with the first year of life, food allergy had decreased by as much as 18.6%, atopic dermatitis decreased by as much as 23.8%, and asthma decreased by as much as 8%, whereas asthma and allergic rhinitis had increased from 6% to 14.8%. More frequent house cleaning negatively correlated with the new onset of atopic dermatitis and of asthma and allergic rhinitis. Hypersensitivity to seasonal allergens and mites and to any other allergen positively correlated with new onset of food allergy, atopic dermatitis, and asthma and allergic rhinitis. Parental atopy positively correlated with the new onset of asthma and negatively correlated with asthma remission. Conclusion: Analysis of our findings indicated that new onset and/or remission of allergic diseases was linked with hypersensitivity to house-dust mites in children who were polysensitized and with parental atopy. In addition, children who had food allergy, allergic rhinitis, or atopic dermatitis at the age of 1 year had more of a chance developing other atopic disease (except asthma) at ages 7-9 years and less of a chance of having a remission of the disease.

Abstract
BACKGROUND Studies indicate that exposure to polycyclic aromatic hydrocarbons (PAH) is associated with adverse respiratory and allergy outcomes. Exposure to PAH may impair the immune function of the foetus and, subsequently, be responsible for an increased susceptibility of children to allergic diseases. OBJECTIVES The aim of the present study was to assess the association between mother's exposure to PAH during pregnancy and allergy diseases in their infants. We also assessed the above associations using measured PAH exposure in children's urine during the first two years of life. METHODS The current analysis was restricted to 455 mothers and their children from Lodz district. The women were interviewed three times during the pregnancy in order to collect demographic, socio-economic and medical history data. Children's health status was assessed at the age of 10-18 months and repeated at two years of age. The associations between dependent dichotomous variables and urine concentrations of 1-hydroxypyrene (1-HP) were analysed using logistic regression. RESULTS We showed that higher urine concentrations of 1-HP in mothers at 20-24 weeks of pregnancy increased the risk of more frequent respiratory infections (p=0.02) in children during their first year of life. Higher 1-HP concentrations in children's urine increased the risk of food allergy (p=0.002) in children during their first two years of life. CONCLUSIONS This study suggests awareness of environmental factors, which may affect children's health since PAH showed to be a risk factor for airway infections and food allergy in children after adjustment for other risk factors.

Abstract
BACKGROUND There are investigations concluding that reduced vitamin D status in pregnancy, may be a risk factor for the development of allergic outcomes in offspring. However, studies on the relationship between cord levels of 25-hydroxyvitamin D (25[OH]D) and risk of early childhood wheezing and early-onset atopic dermatitis/food allergy are very limited. OBJECTIVE To assess the associations between cord blood concentration of 25[OH]D and occurrence of the incidence of wheezing, atopic dermatitis, food allergy, during the first two years of life. METHODS We evaluated 240 children by the age of 2 years from the Polish Mother and Child Cohort Study. Women were interviewed during pregnancy to collect demographic and socioeconomic data, the medical and reproductive history. At delivery, umbilical cord blood plasma was sampled. The child's health status were examined at approximately 2 years. In the analyses multivariable model was used. RESULTS Data from 190 participants were included into the analysis. The median value and quartile range of 25[OH]D in cord blood [ng/ml] were as follows: 6.33, 4.16-8.53. 25[OH]D in cord blood below lower quartile increases the risk of multi-triggered wheezing (MTW) in children during first 2 years of life (OR: 2.81; 95% CI: 1.13-7.00). Higher cord serum level of 25[OH]D reduces the risk of viral induced wheezing (VIW). The cord serum level of 25[OH]D below median value (OR: 6.06; 95% CI: 1.3-28.3) or below lower quartile (OR: 5.43; 95% CI: 1.66-17.7) increases the risk of VIW. All above effects of vitamin D level in cord blood were corrected for the effects other independent risk factors of wheezing and VIW in this cohort. CONCLUSIONS Cord serum 25[OH]D levels were inversely associated with the risk of multi-triggered wheezing, and especially viral-induced wheezing by the age of 2 years, but no association was found with food allergy, atopic dermatitis and frequencies of infections.

Abstract
BACKGROUND One of the most important aspects of sublingual immunotherapy (SLIT) is the regimen of administration. The aim of the study was to compare the efficacy and the safety of SLIT given pre-coseasonally (starting before the pollen season and continuing until the end of it) and continuously (all year round, independent of the pollen season) in children allergic to grass pollen. METHODS Sixty children aged 6-18, sensitive only to grass pollen, with rhinitis (20 patients had concomitant asthma) participated in the 2-year prospective, randomized, double-blind, placebo-controlled trial. RESULTS Both pre-coseasonal and continuous SLIT were associated with a substantial reduction in the combined symptoms/medication score when compared with placebo; there were no significant differences between the regimens (mean difference: 18.1 ± 12.4, P > 0.05). Similar changes were observed in the total symptoms score. Pre-coseasonal therapy, compared with continuous, was more effective in the reduction of nasal symptoms (mean difference: -18.0 ± 2.5, P = 0.006). We did not observe significant differences in medication, ocular, and asthma scores between the regimens. We did not observe changes in morning PEF, FEV1, and PD20 in any of the three groups nor between the groups throughout the study. We showed a significant decrease in FeNO level comparable in both active groups. There were no differences between groups in the induction of CD4CD25Foxp3-positive cells in peripheral blood during the study. CONCLUSION Both protocols were effective compared with placebo and showed similar decreases for combined symptoms/medication score and all secondary endpoints, with the exception of nasal symptoms that were lower in the pre-coseasonal group.

Abstract
BACKGROUND In a previous double-blind placebo-controlled study, we analyzed a high-dose sublingual immunotherapy (SLIT) ultrarush protocol in asthmatic children monosensitized to grass pollen. In the present open-label study, we assessed the effect of SLIT on symptom score and nonspecific bronchial hyperreactivity in the same cohort followed for 1 subsequent year. METHODS The study population comprised 35 children who were enrolled in our previous study. Placebo-treated patients were switched to active treatment; therefore, SLIT was administered for a further year to all patients. SLIT was considered effective if it reduced the severity of clinical symptoms and decreased the use of symptomatic medication. The effect of SLIT on nonspecific bronchial hyperreactivity (methacholine challenge test) was also measured. RESULTS The symptom scores for asthma and rhinitis and medication score remained unchanged in the group who continued SLIT. We also observed further significant improvement in the results of the methacholine challenge test during the third year of treatment. CONCLUSIONS High-dose ultrarush SLIT reduced the severity of allergic symptoms in the first 2 grass pollen seasons but continuously improved bronchial hyperreactivity in children with asthma, suggesting that SLIT should be continued despite the lack of further improvement in clinical symptoms.

Abstract
BACKGROUND Although sublingual immunotherapy (SLIT) has been used with increasing frequency, the data on the efficacy of SLIT in pediatric asthma are limited. AIM The aim of our study was to evaluate the efficacy and the safety of high-dose SLIT given pre-seasonally and co-seasonally in an ultra-rush scheme in children with bronchial asthma allergic to grass pollen. METHODS Fifty children with asthma, aged 6-17, sensitive to grass pollen, participated in the 2-year prospective, randomized, double-blind, placebo-controlled trial, to investigate the efficacy and safety of SLIT (Staloral 300 IR, Stallergenes SA, 25 microg major allergens) as a standardized extract of five grass pollen with ultra-rush induction. RESULTS SLIT significantly improved asthma symptom scores (41% vs. placebo group), reduced nasal symptoms (25% vs. placebo group) and the use of rescue medications (10% vs. placebo group), improved forced expiratory volume in 1 s, but had no effect on ocular symptoms, nasal hyper-reactivity, peak expiratory flow and forced expiratory volume between 25% and 75% of vital capacity. Serum levels of immunoglobulin E and IgG4 did not change after SLIT. After the second season of SLIT, an improvement in bronchial hyperresponsiveness was observed; however, compared with placebo, this effect was not significant. Among all subjects in SLIT group, predominantly local reactions have been recorded in 59% of subjects in the first year of treatment and in 35% in the second. CONCLUSIONS Our study indicated that high-dose ultra-rush, co-seasonal SLIT given for 2 years, was safe and reduced a multiple symptom-medication score.

Abstract
BACKGROUND The effects of leukotriene modifiers on IL-10 production have not been studied in children with asthma. OBJECTIVE The primary objective of this study was to determine the changes in IL-10 concentrations, clinical efficacy and peripheral blood eosinophil counts after treatment with montelukast. METHODS The study was conducted on 27 patients: 13 patients monoallergic to grass pollen during the pollen season (GPs group) and out of the pollen season (GPos group), and on 14 patients monoallergic to house dust mite (HDM) from May to September (HDM group). Main outcome measures were changes in concentrations of IL-10 in the supernatant after a 4-week treatment with montelukast. Measurements of asthma severity score, forced expiratory volume in 1 s (FEV1) and peripheral blood eosinophil counts were the secondary end-points. RESULTS Montelukast resulted in a within-group significant increase in IL-10 concentration in the supernatant in the GPs (54.0 vs. 125.5 pg/mL) and in the HDM (51.2 vs. 77.1 pg/mL) group. Montelukast had no effect on changes of IL-10 concentration in the supernatant from peripheral blood mononuclear cell (PBMC) culture after non-sensitizing allergen stimulation. Montelukast significantly improved asthma control and FEV1, and significantly decreased eosinophil blood count in the GPs and in the HDM group after a 4-week treatment. Montelukast did not lead to changes of all measured parameters within the GPos group. CONCLUSION Montelukast increased IL-10 concentration in supernatants from sensitizing allergen-stimulated PBMC culture obtained from children with asthma monoallergic to grass pollen during the pollen season, and from children with asthma monoallergic to HDM.

Abstract
BACKGROUND Asthma is one of the commonest public health problems in Poland and the commonest chronic disorder in children. Lodz Regional Health Insurance Fund was a sponsor of the Prevention Asthma Program in 2000-03, directed at increasing early detection and providing optimal treatment of allergies by specialists in children. METHODS All funds were divided between 127 primary and 12 specialized care centres participated in the programme. Primary care centre goals were: anamnestic information, mapping of allergy-causing factors, repeated auscultation of the lungs, bronchial dilation test, peak expiratory flow (PEF) measurement at the clinic and at home for 2 weeks. After preliminary diagnosis patients have been send to specialized centres. Specialized care centre goals were as follows: skin testing, spirometry, repeated bronchial dilation test, determination of eosinophilic white blood cells and eosinophil cationic protein (ECP) in blood. RESULTS Increasing trend of new asthma diagnosis, expressed per 1000 inhabitants, was observed from 0.99 in 2000 to 2.19 in 2003. In the first year of Asthma Prevention Program, we observed more hospital episodes because of asthma exacerbation in comparison with year 1999 but from the second year of programme we showed systematically decreasing number of hospital episodes as a result of asthma exacerbation from 1.48 in 2000 to 0.84 in 2003. We found significantly decreasing trend in duration of hospitalization due to asthma exacerbation (P = 0.001). CONCLUSIONS Effects of this programmes are: early identification of allergic diseases, mainly asthma, reduced number and shorter duration of hospitalization because of asthma exacerbation and establishing new Asthma Schools Education.

Abstract
BACKGROUND Asthma morbidity increases every year, especially among children, and exposure to high levels of indoor allergens is a very important factor. We evaluated the prevalence and exposure to cockroach (CR) allergen in asthmatic children in Poland, and also tested the hypothesis that asthma with allergy to CR is more severe than with allergy to other antigens. METHODS One hundred and sixty children with asthma were examined, had skin prick tests (SPT) with common and CR allergens, underwent spirometry, and provocation tests to histamine. Children with positive SPT to CR had measured specific IgE levels to this antigen and Bla g 2 concentrations were measured in their homes. RESULTS The most common allergen, was dust mite 51.3%, followed by pollen 48.8% and CR allergen 24.3%. In children with CR sensitivity, 13% had mild asthma, 26% moderate and 61% had severe asthma. Their levels for forced expiratory volume in one second (FEV1), and the provocative concentration of histamine that caused a 20% fall in FEV1 (PC20), were statistically lower than in the group of children with other than CR allergies. Bla g 2 antigen was detected in 55.13% samples. The highest levels of Bla g 2 were found in old houses, without central heating, and in houses with lower income. CONCLUSION In Polish children, CR allergen is a very important factor of sensitivity. Concentrations of Bla g 2 in homes are higher than previously reported in other European countries, and are strongly related to the houses' characteristics. Also, children with CR hypersensitivity have severe asthma more often than children with other allergies.

Abstract
BACKGROUND Levels of an immunoregulatory and anti-inflammatory cytokine IL-10 are reduced in asthmatic airways, potentially contributing to more intense inflammation. Triamcinolone has anti-inflammatory properties and the anti-inflammatory effects of montelukast and formoterol have been discussed. OBJECTIVE The purpose of this study was to define the effect of treatment with triamcinolone, montelukast and formoterol on the serum level of IL-10, eosinophil blood counts, eosinophil cationic response (ECP) and clinical parameters (symptom score, FEV1 and PC20H) in children with moderate asthma. METHODS An 8-week, placebo-controlled and randomized, double-blind trial was carried out. The subjects were 91 children with moderate atopic asthma who were allergic to dust mite. Patients were randomly allocated to receive 400 microg triamcinolone (n = 19), 5 or 10 mg (according to age) montelukast (n = 18), 24 microg formoterol (n = 18) or placebo (n = 36). RESULTS Seventy-nine children completed the study. After treatment with triamcinolone and montelukast the level of IL-10 in blood serum significantly increased, eosinophil blood counts and ECP levels significantly decreased and all clinical parameters improved; treatment with formoterol had no effect on IL-10 level, eosinophil blood counts in serum and bronchial hyper-reactivity; ECP level significantly decreased after treatment and asthma symptoms and FEV1 improved significantly. Mean IL-10 levels in serum before and after treatment with triamcinolone were 7.23 pg/mL with 95% CI, 6.74 -7.72% and 14.24 pg/mL with 95% CI, 11.6-16.88%, respectively (P < 0.001); with montelukast they were 6.59 pg/mL with 95% CI, 6.26-7.23% and 10.94 pg/mL with 95% CI, 8.24-12.65%, respectively (P < 0.002); with formoterol they were 7.06 pg/mL with 95% CI, 6.61-7.52% and 7.04 pg/mL with 95% CI, 6.15-7.93%. We found statistically significant correlations between serum level of IL-10 and serum level of ECP after treatment with triamcinolone and montelukast. CONCLUSION This study demonstrates that one possible way by which triamcinolone and montelukast contribute to inhibition of inflammation is by increasing IL-10 levels.

Abstract
BACKGROUND It is important to monitor inflammation regularly in asthma in addition to clinical symptoms, and there is a great need for noninvasive tests that could routinely be used in clinical practice. OBJECTIVE Our hypothesis was that the improvement of clinical parameters, together with decreased airway responsiveness, could be correlated with changes in the levels of serum markers of inflammation after a 4-week treatment with triamcinolone. METHODS In this double-blind, randomized, placebo-controlled trial, 48 children, aged 6 to 18 years, with mild to moderate atopic asthma, were randomly allocated to receive triamcinolone or matching placebo for 4 weeks. The following parameters were measured: the symptom score, forced expiratory volume in 1 second (FEV1), provocative concentration of histamine causing a 20% fall in FEV1 (PC20) for histamine and peripheral blood eosinophil count, serum levels of the inflammatory markers eosinophil cationic protein (ECP), soluble receptor of interleukin-2 (sIL-2R), interleukin-4, soluble intercellular adhesion molecule-1 before and after treatment. RESULTS The clinical parameters significantly improved after treatment with triamcinolone; the mean value of FEV1 changed from 74% of predicted value before, to 90% of predicted after treatment (P < 0.001). PC20 for histamine after treatment with triamcinolone increased significantly from the mean value 2.5 mg/mL to 4.7 mg/mL (P < 0.001). Treatment with triamcinolone significantly (P < 0.05) decreased serum levels of all the measured inflammatory markers. The mean concentration of eosinophil blood count was 380 and 261 cells/mm3; ECP, 83 and 58 ng/mL; serum sIL-2R, 734 and 487 pg/mL; soluble intercellular adhesion molecule-1, 266 and 210 ng/mL, before and after treatment, respectively. The values of interleukin-4 were low and close to the sensitivity of the assay. A significant correlation was found between ECP and sIL-2R levels before and after treatment with triamcinolone. CONCLUSIONS A significant decrease of all the measured serum parameters was observed after treatment with triamcinolone; however, no significant correlation was found among any of those parameters and clinical markers of disease severity (such as FEV1 or PC20H).

Abstract
BACKGROUND The purpose of this study was to determine the clinical effect of nedocromil sodium and its relationship with serum levels of inflammatory mediators by monitoring lung function and noninvasive markers of airway inflammation, such as eosinophil blood counts; serum ECP, sIL-2R, IL-4 and sICAM; and total IgE. Anti-inflammatory medications cause a reduction in the markers of airway inflammation, decrease the intensity of airway hyperresponsiveness, and improve clinical symptoms of asthma. Among the available choices is nedocromil sodium, which is favored in the treatment of asthmatic children due to its very mild side-effects. It has been previously shown to improve the clinical parameters of asthma, but there are limited data on its effect on inflammatory mediators in the serum of asthmatic children. METHODS In this double-blind, randomized, placebo-controlled 8-week trial, 39 children, aged 9-16 years, with moderate atopic asthma were randomly allocated to receive either nedocromil sodium, two puffs twice daily, 0.002 g/puff, or placebo, two puffs twice daily. The primary end points were the clinical parameters of asthma measured by asthma symptom score, FEV1, and PC20H. Other end points included the serum levels of various inflammatory markers - ECP, sIL-2R, IL-4, sICAM, and IgE. RESULTS Clinical and inflammatory parameters improved with the use of nedocromil sodium, compared with placebo. Nedocromil significantly decreased serum levels of inflammatory markers, as shown in the following table. No correlation was found between any of the measured parameters. CONCLUSION Nedocromil sodium provided effective anti-inflammatory treatment for children with moderate atopic asthma.
