  Background: Primary prevention of food allergy by early introduction of allergenic foods seems promising. We aimed to determine whether early food introduction or the application of regular skin emollients in infants from a general population reduced the risk of food allergy. Methods: This 2 × 2 factorial, cluster-randomised trial was done at Oslo University Hospital and Østfold Hospital Trust, Oslo, Norway, and Karolinska University Hospital, Stockholm, Sweden. Infants of women recruited antenatally at the routine 18-week ultrasound examination were cluster-randomised at birth to the following groups: (1) no intervention group; (2) the skin intervention group (skin emollients; bath additives and facial cream; from age 2 weeks to

  Aims To identify maternal food-avoidance diets and dietary supplement use during breastfeeding, and to explore factors associated with food avoidance diets. Design A prospective mother–child birth cohort study. Methods Electronic questionnaires were answered by 1,462 breastfeeding mothers 6 months postpartum in the Preventing Atopic Dermatitis and Allergies in Children (PreventADALL) study from 2014–2016. Demographic and antenatal factors were analysed for associations with food avoidance diets in 1,368 women by multiple logistic regression. Results Overall, 289 breastfeeding women (19.8%) avoided at least one food item in their diet, most commonly cow's milk in 99 women (6.8%). Foods were most often avoided due to conditions in the child, maternal factors or lifestyle choice. The odds for food avoidance diets were 2.1 (95% CI: 1.3, 3.4) for food allergy (presumed or diagnosed) and 19.4 (5.4, 70.1) for celiac disease in the mother. Dietary supplements were reported by nearly 80%, most commonly cod liver oil.

  Overweight and atopic dermatitis (AD) are major health problems in most industrialised countries, but the relationship between overweight and AD in infants and young children is unclear. We investigated if weight-for-length at birth, in infancy and at two years, as well as early weight-gain velocity, are associated with the development of AD in early life. Methods Cohort study of infants (n = 642), all living in south-east Norway, hospitalized with acute bronchiolitis (n = 404) or recruited from the general population (n = 238), examined at mean age 5.1 months (enrolment) and at a two-year follow-up visit (n = 499; 78%) at mean age 24.6 months. Exposures were weight-for-length (g/cm) at birth, enrolment and two-year follow-up, and early weight-gain velocity (gram/month from birth to enrolment). Excessive weight-for-length was defined as weight-for-length >95th percentile of WHO child-growth standards. Data on weight-for-length at the three time points were obtained for 435, 428 and 473 children. AD was diagnosed according to the Hanifin & Rajka criteria or from a history of physician-diagnosed AD. We performed multivariate analyses with weight-for-length at birth, at enrolment and at the two-year follow-up visit and with early weight gain velocity for the endpoint AD at each visit. Results In adjusted analyses, excessive weight-for-length at enrolment was associated with concurrent AD (OR 3.03; 95% CI 1.23–7.50) and with AD at two years (OR 2.40; 1.11–5.17). In infants without AD, weight-for-length at enrolment increased the risk of AD at two years, with OR being 1.02 (95% CI 1.00–1.04) per increased gram/cm. AD at two years was not associated with concurrent excessive weight-for-length, nor was AD at any time associated with weight-for-length at birth or with early weight-gain velocity. Conclusions The results suggest that overweight in infancy may contribute to the development of AD in early life, highlighting the need for child health-care professionals to address potential overweight and atopic disease when advising infants’ caregivers.

  Skin barrier function can be evaluated by measuring transepidermal water loss (TEWL).1,2 High TEWL is found in children with atopic eczema (AE)3 and in infants with a mutation in the gene encoding for profilaggrin,4 a precursor for filaggrin, an important protein for skin barrier function. In a recent study by Kelleher et al5, high TEWL at 2 days and 2 months preceded and predicted AE at 1 year, independent of parental atopy and filaggrin mutation status.

  Aim Acute bronchiolitis in infancy increases the risk of later asthma and reduced health-related quality of life (QoL). We aimed to see whether the severity of acute bronchiolitis in the first year of life was associated with QoL nine months later. Methods The parents of 209 of 404 of children hospitalised for acute bronchiolitis in eight paediatric departments in south-east Norway at a mean four months of age (range 0–12 months) completed the Infant/Toddler Quality of Life Questionnaire sent by mail nine months after the acute illness. Disease severity was measured by length of stay and the need for supportive treatment. Interactions with gender, inclusion age, prematurity, maternal ethnicity and maternal education were examined. Results Reduced QoL in four domains was associated with increased length of stay and need for ventilatory support. Physical abilities and general health were associated with both severity markers, whereas bodily pain and discomfort and change in health were associated with length of stay. Ventilatory support was more negatively associated with QoL than atopic eczema and also associated with reduced parental emotions and parental time. Conclusion The severity of acute bronchiolitis in infants was associated with reduced QoL nine months later.

  Aim Acute bronchiolitis increases the risk of asthma, and reduced quality of life (QoL) is reported in children with asthma and allergy. However, the impact of asthma risk factors on QoL is unclear. This study investigated whether bronchiolitis and common asthma risk factors in infancy had an influence on later QoL. Methods The parents of 209 infants recruited during hospitalisation for bronchiolitis at a mean age of 4 months, and 206 controls responded to the generic Infant Toddler Quality of Life Questionnaire 9 months later. We used robust regression analyses to assess the association between four asthma risk factors, atopic eczema, parental asthma, parental allergic rhinoconjunctivitis and second-hand smoke and QoL in the two groups. Results QoL was lower among children with previous bronchiolitis in the overall health and general health domains and lower in six of 13 domains in children with atopic eczema. Compared with no risk factors, children with previous bronchiolitis and three risk factors had lower scores in four domains, and control children with three risk factors had lower scores in three domains. Conclusion Having acute bronchiolitis, atopic eczema and three asthma risk factors were negatively associated with later QoL in early childhood.

  Introduction:  Physical activity (PA) is important in preventing disease, but endurance elite athletes have increased prevalence of asthma and airway inflammation. Objectives:  We aimed to determine if PA was associated with increased fractional exhaled nitric oxide (FENO) in asthmatic and non-asthmatic adolescents. Methods:  FENO was recorded (Niox Mino®, Aerocrine AB, Stockholm, Sweden) in 169 adolescents (13–14 years) in a nested case–control analysis from the Environment and Childhood Asthma study, Oslo, 92 adolescents with and 77 without asthma. They underwent clinical examination, lung function measurements and treadmill run measuring peak oxygen uptake, and objectively recorded PA for four consecutive days. PA was classified as moderate, vigorous and very vigorous, and total number of hours of each category was recorded for each subject. Associations between FENO and PA were tested using linear robust multiple regression analyses. Results:  In non-asthmatic adolescents, FENO was associated with daily hours of vigorous to very vigorous (r = 0.27, P = 0.02) and very vigorous PAs (r = 0.25, P = 0.036) in bivariate analyses. In multivariate analyses, FENO was associated with vigorous to very vigorous PA [regression coefficients (95% confidence interval) 1.9 (0.6, 3.1); P = 0.004] and more strongly with very vigorous PA [3.9 (1.5, 6.4); P = 0.002] in non-asthmatic but not in asthmatic adolescents. Total daily PA was not associated with FENO in either group. Thus, 1 h of very vigorous PA per day increased FENO by 3.9 ppb. Conclusion: Vigorous to very vigorous PA, contrasting total daily PA, was significantly associated with increased FENO in non-asthmatic adolescents, suggesting that intensive PA may induce airway inflammation independent of asthma.

  Limited knowledge exists about development of bronchial hyperresponsiveness (BHR) through adolescence. We aimed to assess changes in and risk factors for BHR in adolescence. From a Norwegian birth cohort 517 subjects underwent clinical examinations, structured interviews and methacholine challenges at age 10 and 16. BHR was divided into four categories: no BHR (cumulative methacholine dose required to reduce FEV1 by 20% (PD20) >16 μmol), borderline BHR (PD20 ≤16 and >8 μmol), mild to moderate BHR (PD20 ≤8 and >1 μmol), and severe BHR (PD20 ≤ 1 μmol). Logistic regression analysis was used to assess risk factors and possible confounders. The number of children with PD20 ≤ 8 decreased from 172 (33%) to 79 (15%) from age 10–16 (p < 0.001). Most children (n = 295, 57%) remained in the same BHR (category) from age 10–16 (50% with no BHR), whereas the majority 182 (82%) of the 222 children who changed BHR category, had decreased severity at age 16. PD20 ≤ 8 at age 10 was the major risk factor for PD20 ≤ 8 6 years later (odds ratio 6.3), without significant confounding effect (>25% change) of gender, active rhinitis, active asthma, height, FEV1/FVC, or allergic sensitization. BHR decreased overall in severity through adolescence, was stable for the majority of children and only a minority (8%) had increased BHR from age 10 to 16. Mild to moderate and severe BHR at age 10 were major risk factors for PD20 ≤ 8 at 16 years and not modified by asthma or body size.

  Aim. To determine whether five months of guided active play in overweight or obese children and adolescents under multi-disciplinary management for weight reduction leads to increased physical activity levels in leisure time, as well as changes in aerobic fitness and body composition. Methods. Sixty overweight or obese children and adolescents were randomly assigned to an intervention or control group. All participants received dietary advice and were encouraged to increase physical activity level. The intervention group additionally participated in 60-minute guided active play/physical activity twice a week for 5 months. Physical activity was recorded; aerobic fitness and body composition were measured at inclusion and after cessation of intervention. Results. Physical activity level during weekend days was significantly higher for the intervention group compared with the controls after 5 months intervention (p=0.04). The mean reduction in percentage of body fat was 1.8% (95%CI: 0.6, 3.1) in the intervention group (p=0.04) and not significant among the controls (0.9 [−0.9, 2.7]). There was no change in aerobic fitness. Conclusion. Five months of guided active play was associated with increased physical activity levels during weekend days and reduced body fat, although weakly, in overweight and obese children and adolescents participating in multi-disciplinary weight reduction programmes.

  Endothelin-1 (EDN1) has been reported to be implicated in the pathophysiology of asthma. Literature results on the genetic association of EDN1 in asthma are inconsistent. Eleven single nucleotide polymorphisms in EDN1 were genotyped in 342 and 100 families from UK and Norway, respectively. Asthma, bronchial hyperreactivity (BHR) and atopic asthma phenotypes were analyzed for the family-based association. Five single nucleotide polymorphisms (SNPs) were associated with asthma (0.0017P0.0291), five with BHR (0.0026P0.0315) and three with atopic asthma (0.0016P0.041) in the UK population. Three SNPs were associated with asthma (0.0041P0.019), seven with BHR (0.0018P0.041) and two with atopic asthma (0.0123P0.0153) in the Norwegian population. A polymorphism (rs1800541) in the promoter region of EDN1 was replicated in the two populations. A nonsynonymous coding polymorphism (rs5370) resulting in a change of amino acid Asn to Lys at position 198 was also replicated. The results of haplotype-based association analyses strongly supported the ones of single SNP associations. This study demonstrates the significant evidence of association between polymorphisms in EDN1 and asthma

T cell–specific T-box transcription factor haplotype is associated with allergic asthma in children. Journal of Allergy and Clinical Immunology. ISSN 0091-6749. 121. doi: 10.1016/j.jaci.2007.07.068. Vis sammendrag

  BACKGROUND: T cell-specific T-box transcription factor (T-bet) is a member of the T-box family of transcription factors regulating lineage commitment of T(H) lymphocytes toward a predominant T(H)1 phenotype. Asthma and allergy are common complex diseases characterized by T(H)2-mediated inflammation. OBJECTIVE: We aimed to assess possible relationships between the T-bet gene (TBX21) and asthma and allergy in children. METHOD: Twelve single nucleotide polymorphisms (SNPs) in the TBX21 region were genotyped in 948 children from the Environment and Childhood Asthma study. Allele and haplotype frequencies were compared in children with and without asthma (by 10 years) and allergy (>/=1 positive skin prick test response), as well as for the quantitative traits bronchial hyperresponsiveness determined by means of methacholine bronchial challenge testing, lung function determined by means of forced flow volume loops, fractional exhaled nitric oxide measurement, eosinophil count, and serum total IgE level. RESULTS: Allergic asthma was significantly associated with 2 of the tested SNPs (rs11650354 and rs16947078) and further associated with the particular haplotype including these SNPs, with homozygote status resulting in an odds ratio of 8.3 (95% CI, 2.5-26.9) for allergic asthma. Neither nonallergic asthma or "allergy alone" nor the remaining quantitative variables were associated with TBX21 SNPs or haplotypes. CONCLUSION: An association between a specific TBX21 haplotype and allergic asthma in children is demonstrated for the first time and might explain previously detected associations between SNPs within TBX21 and asthma and bronchial hyperresponsiveness. CLINICAL IMPLICATIONS: T-bet genetics might identify individuals at risk for allergic asthma

  Background It is debated whether early treatment with inhaled corticosteroids (ICS) can change the natural course of childhood asthma. Aim To assess if ICS treatment before 2 years of age in children with obstructive airways disease reduces current asthma at 10 years of age. Methods Children with (n=233) and without (n=219) recurrent (r) bronchial obstruction (BO) attending clinical examination at 2 years of age in the birth cohort Environment and Childhood Asthma study in Oslo, were reinvestigated at 10 years of age. Current asthma (CA) at 10 years was defined as asthma with either symptoms and/or asthma treatment during the last year, and/or 10% fall in forced expired volume in 1 s after standardized treadmill run. The risk of CA was assessed by logistic regression and propensity modelling (including gender, parental atopy and severity score at 2 years) in children with rBO who received ICS or not by 2 years. Results CA was found in 97 children, more often among rBO children with (56.9%) and without ICS treatment (30.8%) compared to no-BO children (5.5%) (p<0.001). In rBO children logistic regression analyses (adjusted odds ratio aOR (95% confidence interval)) identified male gender (aOR 1.82 (1.01–3.27), p=0.046) and severity score at 2 years 1.14 (1.03–1.28), (p=0.01), as significant and ICS treatment as non-significant 2.00 (0.98–4.12) risk factors for CA. With propensity modelling adjusting for disease severity, ICS treatment by 2 years caused a non-significant increased risk aOR of CA of 1.84 (0.89–3.82). Conclusion No evidence was found that early use of ICS before age two in children with rBO reduces current asthma 8 years later.

  Background: Eosinophil cationic protein (ECP) is a potent cytotoxic secretory protein with bactericidal and antiviral properties. ECP is released by activated eosinophils and regarded as a marker of eosinophilic inflammation. High levels of ECP have been reported in cases of active asthma and other allergic diseases. This study aimed to assess whether three single-nucleotide polymorphisms (SNPs) in the ECP gene (RNASE3) on chromosome 14 q24–q31 or their haplotypes are associated with asthma, allergy, or related phenotypes. Methods: The three SNPs −38CA, +371CG and +499CG in RNASE3 and their haplotypes were analyzed for associations with asthma, serum-ECP (s-ECP) levels, allergic sensitization (positive skin-prick test to common allergens), bronchial hyperresponsiveness (BHR) assessed by methacholine inhalation, and serum-IgE (s-IgE) levels in 177 families from Norway and the Netherlands identified through siblings with asthma. Results: Transmission disequilibrium test (TDT) demonstrated significant associations between the A-G-G haplotype and asthma as well as the specific phenotypes allergic asthma (but not non-allergic asthma), high s-ECP, high s-IgE and BHR, while the C-G-G haplotype was associated with reduced occurrence of these traits. In addition, the −38A allele was associated with high s-ECP levels and allergic asthma. Conclusion: The present study suggests that the A-G-G haplotype in the RNASE3 gene influences the development of asthma, in particular, an allergic form of asthma. Furthermore, as the −38CA SNP lies in close vicinity of known intron-regulatory sites, results of SNP analysis suggest that the detected association is possibly linked to a genetic transcriptional control of s-ECP levels.

  Background: The HLA (human leukocyte antigen) class II genes DQB1 and DRB1 and the Tumor Necrosis Factor α gene (TNFA) within the HLA complex (chromosome 6p21) have been associated with asthma and allergy. Due to the strong linkage disequilibrium characterizing this complex and the multiple asthma/allergy expressions, we aimed to determine which of these genes were primarily involved in specific asthma/allergy traits. Methods: The DRB1–DQB1 alleles and TNFA-308 polymorphism were genotyped in 959 children from the Environment and Childhood Asthma study and analyzed for possible associations with allergic and non-allergic asthma (with/without at least one positive skin prick test for allergens) and specific allergic sensitization, as well as bronchial hyperresponsiveness and total IgE, using both allele and extended haplotype analyses. Results: Different genes within the HLA complex were associated with separate asthma and allergy traits. Nonallergic asthma was associated with both the TNFA-308A allele [Odds ratio (OR) 1.7 (1.3–2.3)] and DRB1*03 allele [OR 1.6(1–2.6)], but extended DRB1*03-TNFA-308 haplotype analysis suggested that the DRB1–DQB1 association was secondary to linkage disequilibrium with the TNFA-308 polymorphism. Allergies were associated with HLA class II alleles only; birch sensitization with DQB1*0603-DRB1*13 [OR 2.3 (1.4–4.0)] and mugwort sensitization with DQB1*0609-DRB1*13 [OR 7.1 (1.9–27.0)] and DQB1*0501-DRB1*01 [OR 2.0 (1.0–4.0)]. Conclusions: Our data suggests that asthma is not associated with DRB1 or DQB1 but rather TNFA or a gene(s) in linkage disequilibrium, while sensitization to specific allergens is associated with particular alleles at the DQ and/or DR loci. A novel association between DQB1*0603-DRB1*13 and birch allergy is identified

  The aim of the study was to assess if lung function at birth predicts lung function at 2 yr and secondly, if lung function development was influenced by the common phenotypes of recurrent bronchial obstruction (rBO) or atopic eczema (AE) by 2 yr. Lung function was assessed at birth (n = 802) and at 2 yr within the prospective birth cohort study ‘the Environment and Childhood Asthma Study’ in Oslo. The 135 children with lung function measured at birth by tidal flow volume (TFV) loops and passive respiratory mechanics, who were included in a nested case–control study were reinvestigated at 2 yr with clinical examination, TFV loops (n = 90) (mean age 26.6 (3.7 s.d.) months), skin prick test and parental interview. Children were categorized into quartiles (lower, middle two, upper) according to time to peak tidal expiratory flow/total expiratory time (tPTEF/tE) at birth as well as clinical phenotype based on the presence of rBO and/or AE (ever) by 2 yr. The observed reduction in mean tPTEF/tE from birth to 2 yr within the quartiles, were not significantly different after controlling for ‘regression to the mean’. tPTEF/tE at birth correlated significantly with tPTEF/tE at 2 yr, (r = 0.475, p < 0.001). Children with both rBO and AE by 2 yr had significantly lower tPTEF/tE at 2 yr (p = 0.002) and at birth (p = 0.027), compared with children with no rBO or AE. Clinical phenotype at 2 yr did not influence the change in tPTEF/tE from birth to 2 yr. This study demonstrates a clear tracking of lung function from birth, not influenced by rBO or AE by 2 yr.

  Background: The western world's increase in childhood asthma is suggested to level off. We aimed to investigate asthma prevalence in 10-year-old children within the prospective birth cohort Environment and Childhood Asthma (ECA) Study in Oslo established in 1992/1993. Subjects and methods: Six hundred and sixteen (77%) of 803 children (mean age 10.9 ± 0.9 (SD) years) with lung function measurements at birth were reinvestigated at age 10 years. At birth they corresponded to the entire birth cohort (n = 3754) regarding gender, socio-demographic factors, parental allergic diseases, pet keeping and maternal smoking. Results from structured parental interview, spirometry, and skin prick test for inhalant and food allergens are presented. Asthma definition required minimum two positive criteria, (i) doctor's diagnosis of asthma, (ii) wheeze and/or chest tightness, (iii) use of anti-asthmatic treatment. Current asthma required asthma definition plus either (ii) and/or (iii) in the last 12 months, and/or ≥10% fall in forced expired volume in 1 s after treadmill running. Results: Lifetime prevalence of asthma was 20.2%; current asthma 11.1%, doctor diagnosis of asthma 16.1% and wheezes ever 30.3%. Allergic sensitization (29.3% overall) was more common among children with current (56.3%) compared to asymptomatic (last 12 months) (26.0%) or no asthma (27.6%) (P < 0.001). Boys more often than girls had current asthma (14.4 vs 7.1%, P = 0.004), wheeze ever (36.9 vs 22.5%, P = 0.002) and allergic sensitization (36.2 vs 22.1%, respectively, P < 0.001).

At birth they corresponded to the entire birth cohort (n = 3754) regarding gender, socio-demographic factors, parental allergic diseases, pet keeping and maternal smoking. Results from structured parental interview, spirometry, and skin prick test for inhalant and food allergens are presented. Asthma definition required minimum two positive criteria, (i) doctor's diagnosis of asthma, (ii) wheeze and/or chest tightness, (iii) use of anti-asthmatic treatment. Current asthma required asthma definition plus either (ii) and/or (iii) in the last 12 months, and/or > or = 10% fall in forced expired volume in 1 s after treadmill running. RESULTS: Lifetime prevalence of asthma was 20.2%; current asthma 11.1%, doctor diagnosis of asthma 16.1% and wheezes ever 30.3%. Allergic sensitization (29.3% overall) was more common among children with current (56.3%) compared to asymptomatic (last 12 months) (26.0%) or no asthma (27.6%) (P < 0.001). Boys more often than girls had current asthma (14.4 vs 7.1%, P = 0.004), wheeze ever (36.9 vs 22.5%, P = 0.002) and allergic sensitization (36.2 vs 22.1%, respectively, P < 0.001). CONCLUSION: Childhood asthma apparently continues to increase in Oslo, having affected every fifth 10-year-old child.

  The endotoxin receptor soluble CD14 (sCD14) has been implicated in the 'hygiene hypothesis' suggesting reduced allergic sensitization with bacterial stimulation. However, the relationship between early life sCD14 and allergic diseases is conflicting. We aimed to investigate whether possible risk factors for allergic diseases were associated with sCD14 levels at 2 yr of age. In the nested case-control study of the birth cohort studies 'Environment and Childhood Asthma study in Oslo' 411 children selected with recurrent bronchial obstruction (rBO) (n=241) and no bronchial obstruction (n=170) by 2 yr were investigated with skin prick test and structured parental interview at age 2 yr. Exposure to tobacco smoke, pets and infections was recorded semi-annually by questionnaires (0-2 yr). The sCD14 was analysed from frozen, stored serum by ELISA technique. Regression analyses were performed in all subjects with complete data (n=406, 180 girls), and in girls and in boys separately. Mean sCD14 (ng/ml) was significantly higher among girls 2035 (1973-2096) vs. 1947 (1890-2004) (boys). The sCD14 was significantly reduced among girls exposed to antenatal maternal smoking and with parental asthma, after adjusting for age, parental rhino-conjunctivitis, pet keeping and childhood infections. Recurrent otitis media (OM) increased and common colds significantly decreased sCD14 levels in girls. Boys with atopic dermatitis and rBO had reduced sCD14. Pet exposure was not significantly associated with sCD14. We report novel gender-related effects of sCD14 in early life and suggest that gender, tobacco smoke exposure, age and middle ear disease in particular should be accounted for when assessing the role of sCD14 in childhood allergic diseases.

  Background Reduced lung function in early infancy has been associated with later obstructive airway diseases. We assessed whether reduced lung function shortly after birth predicts asthma 10 years later. Methods We conducted a prospective birth cohort study of healthy infants in which we measured lung function shortly after birth with the use of tidal breathing flow-volume loops (the fraction of expiratory time to peak tidal expiratory flow to total expiratory time [tPTEF/tE]) in 802 infants and passive respiratory mechanics, including respiratory-system compliance, in 664 infants. At 10 years of age, 616 children (77%) were reassessed by measuring lung function, exercise-induced bronchoconstriction, and bronchial hyperresponsiveness (by means of a methacholine challenge) and by conducting a structured interview to determine whether there was a history of asthma or current asthma. Results As compared with children whose tPTEF/tE shortly after birth was above the median, children whose tPTEF/tE was at or below the median were more likely at 10 years of age to have a history of asthma (24.3% vs. 16.2%, P=0.01), to have current asthma (14.6% vs. 7.5%, P=0.005), and to have severe bronchial hyperresponsiveness, defined as a methacholine dose of less than 1.0 µmol causing a 20% fall in the forced expiratory volume in 1 second (FEV1) (9.1% vs. 4.9%, P=0.05). As compared with children whose respiratory-system compliance was above the median, children with respiratory compliance at or below the median more often had a history of asthma (27.4% vs. 14.8%; P=0.001) and current asthma (15.0% vs. 7.7%, P=0.009), although this measure was not associated with later measurements of lung function. At 10 years of age, tPTEF/tE at birth correlated weakly with the maximal midexpiratory flow rate (r=0.10, P=0.01) but not with FEV1 or forced vital capacity.

  Summary Background Several candidate genes have been implicated in the etiology of asthma, including the gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR). Mutations in the CFTR gene result in derangements of mucociliary clearance. Homozygotes for CFTR mutations develop cystic fibrosis (CF), a disorder characterized mainly by lung and pancreas disease. Objective To investigate whether there was an increased frequency of CFTR mutations in asthma patients. Methods Seven hundred and three subjects aged 10–11 years from the environment and childhood asthma (ECA) study were included in the present study. Possible associations between asthma, reduced lung function, bronchial hyperresponsiveness (BHR), and increased or decreased nitrogen oxide (NO) levels (based on structural parental interview, spirometry, PD20 methacholine challenge test and exhaled NO measurements), and the five most common CFTR mutations in Norway (ΔF508, R117H, R117C, 4005+2T→C, 394delTT), the modulating polymorphisms IVS8(TG)mTn and the IVS8-5T were investigated. Results No association were found between asthma, reduced lung function, BHR or exhaled NO levels and CF heterozygosity. However, the IVS8(TG)11T7 haplotype was associated with normal lung function. Conclusions Our results do not support the hypothesis that CFTR mutations or polymorphisms play a role in the pathogenesis of asthma in children. However, the distribution of Tn(TG)m haplotypes differed between individuals with reduced lung function and individuals with normal lung function

  AIM: To assess the associations between nutrition supplements in infancy and later asthma and allergy in school-age children, and to explore the impact of environmental factors in early life. METHODS: Five hundred and two children underwent clinical examination, skin prick test and a second parentally completed questionnaire within 2 y of a cross-sectional questionnairebased study, including 4585 primary school children (6-16 y old) in 1994 from urban Oslo (37%), the mountainous area of Hallingdal (42%), and the industrial, coastal area of Odda (21%). The children were selected from the 1994 survey on the basis of reported diagnosed asthma (n=166), wheeze in the last 12 mo (n=155) and no asthma/no wheeze (n=181). Questions were related to nutrition and environmental exposure in early life. Possible associations between allergic sensitization or asthma at school age and exposures were estimated by logistic regression analysis, adjusting for potential confounders. RESULTS: Daily intake of fresh fruit or vegetables, but not extra vitamins or cod liver oil supplements, in infancy decreased the risk of asthma (adjusted odds ratio (aOR) 0.57 (95% confidence interval (CI): 0.37-0.88). Early supplements of cod liver oil and extra vitamins were associated with increased allergic sensitization (aOR 1.78 (95% CI: 1.03-3.07) and 1.71 (95% CI: 1.01-2.88), respectively). A significantly higher prevalence of allergic sensitization was found in children living in Hallingdal compared to Odda, while the latter children, on the other hand, had the highest prevalence of house dust mite allergy (p = 0.001 vs Hallingdal and p = 0.04 vs Oslo). CONCLUSION: The present study suggests that the early introduction of daily fresh fruit or vegetables may decrease the risk of asthma after 1 y of life, whereas allergic sensitization at school age seemed to increase with extra vitamin and cod liver oil supplements during infancy. Living area influenced allergic sensitization, with differences between coastal and inland areas.

  Skin prick testing (SPT) is the standard method for diagnosing allergic sensitization but is to some extent performed differently in clinical centres across Europe. There would be advantages in harmonizing the standard panels of allergens used in different European countries, both for clinical purposes and for research, especially with increasing mobility within Europe and current trends in botany and agriculture. As well as improving diagnostic accuracy, this would allow better comparison of research findings in European allergy centres. We have compared the different SPT procedures operating in 29 allergy centres within the Global Allergy and Asthma European Network (GA(2)LEN). Standard SPT is performed similarly in all centres, e.g. using commercial extracts, evaluation after 15-20 min exposure with positive results defined as a wheal >3 mm diameter. The perennial allergens included in the standard SPT panel of inhalant allergens are largely similar (e.g. cat: pricked in all centres; dog: 26 of 29 centres and Dermatophagoides pteronyssinus: 28 of 29 centres) but the choice of pollen allergens vary considerably, reflecting different exposure and sensitization rates for regional inhalant allergens. This overview may serve as reference for the practising doctor and suggests a GA(2)LEN Pan-European core SPT panel

  Environmental tobacco smoke and constituents are global risks for human health. Considerable evidence shows that environmental tobacco smoke exposure contributes to, and exacerbates, respiratory disorders. This review assesses the causal role of environmental tobacco smoke exposure for childhood respiratory disorders, and in particular asthma. Tobacco smoke and environmental tobacco smoke exposure during pregnancy have an effect upon lung function in newborn infants; exposure after birth also has an effect upon lung function. An effect upon bronchial responsiveness has been suggested but the evidence is not as strong as for lung function. From 1997 to 1999 a comprehensive set of systematic reviews concerning the relationship between exposure to environmental tobacco smoke and respiratory health in children summarized the results from hundreds of published papers. The evidence for a causal relationship between environmental tobacco smoke exposure and asthmatic symptoms on the one hand, and between environmental tobacco smoke exposure and reduction in lung function on the other hand, was quite strong, whereas the evidence between environmental tobacco smoke exposure and development of allergy was much weaker. Here we present an overview of the effects of environmental tobacco smoke exposure on lung health in children. A hypothesis has been put forward regarding upregulation of pulmonary neuroendocrine cells in relationship to mechanisms of tobacco smoke products (TSP)-induced pulmonary disease. It has also been reported that genetic variation makes part of the population especially vulnerable to environmental tobacco smoke exposure during pregnancy. Furthermore, there is a need for intervention to reduce environmental tobacco smoke exposure in young children, by educating parents and adolescents about the health effects of environmental tobacco smoke exposure. Studies are needed to identify possible critical periods when environmental tobacco smoke exposure is more likely to induce harmful effects on lung health in young children in order to implement effective preventive strategies.

  The objectives of the present study were to determine the use of inhaled corticosteroids (ICS) for treating recurrent bronchial obstruction (rBO) in young children up to 2 yrs of age and to assess possible modifying effects of ICS on lung function in young children with rBO. From an observational, noninterventional birth cohort of 3,754 newborn children (3,697 with complete questionnaire data by 2 yrs of age), 306 children with documented rBO by age 2 yrs (cases) were identified along with 306 matched controls. Two tidal flow/volume measurements were taken, one at presentation of disease (children were steroid naive) and one at 2 yrs of age (mean age 11.2 and 25.6 months, respectively), from: 21 cases who subsequently received ICS (ICS+); 33 who did not (ICS-); and in 15 controls. The mean +/- SD duration of ICS treatment was 10.3 +/- 6.5 months. The main outcomes were treatment with ICS and baseline ratio of time to peak expiratory flow/total expiratory time (tPTEF/tE). From the entire cohort, 77 children (2.1%) and 21% of children with rBO had received ICS by 2 yrs of age. Baseline tPTEF/tE was significantly lower at the first visit only in ICS+ as compared to ICS- subjects, as well as in ICS+ and ICS- as compared to controls. The mean difference in baseline tPTEF/tE from first to second visit was borderline statistically significant in the ICS+ group only and correlated significantly with duration of ICS treatment. The present observational cohort study demonstrated that one-fifth of young children with recurrent bronchial obstruction had received inhaled corticosteroids. Early inhaled corticosteroid treatment improved lung function by age 2 yrs, mostly in those with the longest duration of treatment.

  Factors that might influence lung function bronchodilator response by 2 yr of age is largely unknown, thus we aimed to assess this in the 'Environment and Childhood asthma' (ECA) study in Oslo. A clinical investigation at mean age 26 months was attended by 516 (84%) children included in a nested case-control study [children with recurrent bronchial obstruction (rBO)] (n = 265) and controls without a history of lower respiratory disease (n = 251). Tidal lung function measures before and after inhaled nebulized salbutamol (bronchodilator response) (when clinically without BO) were obtained in 46%. Clinical characteristics and personal and family history of allergic/respiratory diseases (asthma risk factors) were ascertained by structured interview and clinical examination. Allergic sensitization was assessed by skin prick test/specific IgE antibody analyses to common allergens. Mean (95% CI) per cent change in time to reach peak flow/total expiratory time (tPTEF/tE) from before to after salbutamol was significantly larger in children with rBO [17.3 (9.4-25.3) than controls (2.2 (7.7 to 3.0)]. The bronchodilator response increased significantly (p = 0.001) with increasing number of asthma risk factors, but was not significantly associated with allergic sensitization, parental 'atopy', or maternal smoking alone. Children treated with inhaled corticosteroids had greater bronchodilator response than those treated with bronchodilators alone. Bronchodilator response in asymptomatic 2-yr-old children was most closely associated with the presence of rBO, but increasing number of asthma risk factors and treatment with inhaled corticosteroids were associated with increased bronchodilator response

  Background: Little is known about cockroach sensitisation in Scandinavia, whereas cockroach is implicated in allergic diseases throughout large parts of the world. In association with the Genetics of Asthma International Network study, we report sensitivity to cockroaches and it¡¦s possible association with atopic diseases in Norway. Methods: 100 Norwegian families (426 subjects) of 7-35 years old sib-pairs with asthma and their parents underwent questionnaire/interview (medical and exposure history), skin prick test (SPT) to common local inhalant allergens and German cockroach, and specific IgE to mites, mosquito, shrimp and cockroach. Cockroach sensitivity was defined as positive (¿d3 mm) skin prick test and/or s-IgE ¿d class 2. Results: Thirty-one subjects (7.5%) were sensitised (five mono-sensitised) to cockroach (27 by skin prick test and seven by s-IgE (all with additional inhalant allergy)). Co-sensitisation was most commonly to grass (in 61 %), cat (48 %), dog (48%) and mite (42%). Reported allergic diseases in cockroach sensitive subjects were asthma and rhinitis (n=10), asthma only (n=9), rhinitis only (n=2) and neither asthma nor rhinitis (n=10). Conclusion: Since cockroach sensitivity was relatively frequent in Norwegian atopic families, albeit unclear clinical implications, we suggest that cockroach allergy should be considered in subjects with atopic respiratory disease.

  Lungefunksjonsmålinger hos små barn har vært lite utbredt innen klinisk praksis fordi målinger medfører ekstra utfordringer hos de minste. Utvikling av nye metoder vil komme til å gi nye muligheter for diagnostikk og innsikt i utviklingen av lungefunksjonen hos små barn. Det vil stilles helt spesielle krav til disse målingene. Denne oversikten vil omhandle lungefunksjonsmålinger av barn som ikke er intubert og fokusere på gjennomføringen av de vanligste målemetoder fremfor nytteverdien i ulike sammenhenger.

  What factors influenced the use of inhaled corticosteroids in 2 year old children with recurrent bronchial obstruction? Authors: Chandra Sekhar Devulapalli M.D1*, Geir Haaland M.D2, Morten Pettersen M.D2, Kai-Håkon Carlsen M.D, Ph.D1, Karin Lødrup Carlsen M.D, Ph.D2 Institutions: 1Voksentoppen Asthma and Allergy Centre, National Hospital of Norway, Oslo, Norway and 2Department of Paediatrics, Ullevaal University Hospital, Oslo, Norway. Body: Background: From the prospective observational birth cohort study (Environment and Childhood Asthma study, Oslo), we assessed factors that possibly related to inhaled corticosteroid (ICS) therapy in 25 months old children with recurrent/persistent bronchial obstruction (rBO). Methods and subjects: By structured interview at 25 months, duration and severity (months with persistent symptoms) of bronchial obstruction (BO), atopic dermatitis (AD), and at 11 months total IgE and serum eosinophilic cationic protein (ECP) were assessed in 59 children with rBO who by two years had received ICS (rBO+) and 226 children with rBO without ICS (rBO-). Compliance of the respiratory system (Crs/kg.body weight) by single occlusion technique was measured at birth in 60 of the children, rBO+ (8) and rBO-(52). Mean duration of ICS treatment was 7.4 ± 5.1 months. Results: Duration (mean, 95 % CI) (9.2, 6.9-11.5 vs. 4.7, 3.9-5.5 months) and severity of disease (7.2, 5.0-9.4 vs. 1.1, 0.7-1.6 months of persistent BO) were significantly increased in children with rBO+ compared to rBO-. Crs/kg at birth was significantly lower in rBO+ (0.9, 0.6-1.2 vs. 1.3, 1.1-1.37, p= 0.05). There was no difference in serum ECP (22.0, 15.2-28.9 vs. 18.7, 15.4-22.1) or total IgE (29.5, 1.3-55.8 vs. 30.7, 16.9-44.6), respectively, at the debut of their disease (11 months). However, significantly more rBO+ children had AD (15.6%) compared to rBO- (8.9%). Conclusion: Although clinically observed disease was the most significant determinant for ICS treatment by two years, this was not reflected in eosinophil activation or total IgE measured shortly after debut of their disease, but in Crs/kg at birth in children with rBO.

  EARLY RISK FACTORS FOR TREATMENT WITH INHALED CORTICOSTEROIDS BY 2 YEARS OF AGE C.S. Devulapalli ¹, G. Haaland ², K-H Carlsen ¹, K. L. Carlsen ², M. Pettersen ² ¹ Voksentoppen Asthma and Allergy Centre, National Hospital of Norway, Oslo, Norway ² Department of Paediatrics, Ullevaal University Hospital, Oslo, Norway Background: Early risk factors for moderate to severe early recurrent/persistent bronchial obstruction (rBO) are not well known. Therefore, we assessed factors that were potential risk factors for receiving treatment with inhaled corticosteroid (ICS) therapy by two years of age. Methods: 564 children (50% with rBO) from the prospective observational birth cohort study (Environment and Childhood Asthma study, Oslo) were assessed within the first two years of life by clinical, biochemical and/or physiological characteristics, particularly in relation to rBO. Lung function was assessed by tidal breathing flow volume parameters (tPTEF/tE; time to reach peak expiratory flow/total expiratory time) at birth and at debut of rBO and by compliance of the respiratory system (Crs/kg.body weight) at birth. Atopic dermatitis (AD) ever, serum IgE and serum ECP at 11 months and lung function at two years of age were included in a linear regression model to explore possible risk for ICS treatment by age two. Results: Lung function at birth was significantly reduced among the children with rBO who had received ICS by two years measured by Crs/kg (0.9, 0.6-1.2 vs. 1.3, 1.1-1.37, p= 0.05) (mean, 95 % CI), but not by tPTEF/tE. Having rBO (0.2; 0.28-0.50) (B;95%CI) and any time AD (0.07; 0.02-0.12) significantly increased the risk of receiving ICS. When adding lung function at birth, Crs/kg (-0.103; -0.201- -0.004), but not tPTEF/tE significantly increased the risk for ICS treatment, as did tPTEF/tE at 11 months. Conclusion: Reduced lung function both at birth (particularly assessed by Crs/kg) and at debut of rBO as well as AD increased the risk of later being treated by ICS within the first two years of life. Clinical duration and severity of disease, but not eosinophil activation or IgE before 12 months was associated with increased risk of ICS treatment in this observational, ¿real life¿, non-interventional study.

  DOES INHALED CORTICOSTEROIDS INFLUENCE LUNG FUNCTION IN 2 YEAR OLD CHILDREN ? C.S. Devulapalli *, G. Haaland +, M. Pettersen +, K-H. Carlsen *, K.Lødrup Carlsen + * Voksentoppen Asthma and Allergy University Clinic, National Hospital of Norway, Oslo, Norway + Department of Paediatrics, Ullevaal University Hospital, Oslo, Norway Background: Little information is available about possible influence of inhaled corticosteroids (ICS) on the lung function in young children. From the prospective birth cohort (Environment and Childhood Asthma study, Oslo), we wanted to assess possible influence of ICS treatment between 11 months and 25 months of age on lung function in children with recurrent/persistent bronchial obstruction (rBO). Methods and subjects: Lung function by tidal breathing (SensorMedics 2600) was measured at 11 months and 25 months in 21 children with rBO treated with ICS (rBO+), 32 children with rBO without ICS (rBO-) and 18 healthy controls. Mean duration of ICS treatment was 9.0 months (6.0 SD). The main tidal breathing parameter was the ratio of time to peak flow/total expiratory time (tPTEF/tE). Results: Lung function (mean, 95% CI) was significantly lower among children with rBO+ compared with rBO- and controls, at 11 months (rBO+ 0.17, 0.15-020, rBO- 0.23, 0.19-0.28, controls 0.32, 0.25-0.38) and 25 months (rBO+ 0.23, 0.18-0.29, rBO- 0.28, 0.24-0.32, controls 0.30, 0.24-0.36). However, the change in lung function between 11 months and 25 months was not significantly different between rBO+ and rBO- groups. Conclusion: Treatment with ICS did not improve lung function significantly in young children with rBO.
