We longitudinally analysed the trajectory of Der p 23-specific IgE antibody (sIgE) levels throughout childhood and youth, their early-life determinants and their clinical relevance for allergic rhinitis and asthma. Methods We obtained sera and clinical data of 191 participants of the German Multicentre Allergy Study, a prospective birth cohort. Serum samples from birth to 20 years of age with sIgE reactivity to Der p 23 in a customised semiquantitative microarray were newly analysed with a singleplex quantitative assay. Early mite exposure was assessed by measuring the average content of Der p 1 in house dust at 6 and 18 months. Results Der p 23-sIgE levels were detected at least once in 97/191 participants (51\%). Prevalence of Der p 23 sensitisation and mean sIgE levels increased until age 10 years, plateaued until age 13 years and were lowest at age 20 years. Asthma, allergic rhinitis (AR) and atopic dermatitis (AD) were more prevalent in Der p 23-sensitised children, including those with monomolecular but persistent sensitisation (11/97, 11\%). A higher exposure to mites in infancy and occurrence of AD before 5 years of age preceded the onset of Der p 23 sensitisation, which in turn preceded a higher incidence of asthma. Conclusions Der p 23 sensitisation peaks in late childhood and then decreases. It is preceded by early mite exposure and AD. Asthma and AR can occur in patients persistently sensitised to Der p 23 as the only mite allergen, suggesting the inclusion of molecular testing of Der p 23-sIgE for subjects with clinical suspicion of HDM allergy but without sIgE to other major D.pt. allergens.}, language = {en} } @article{GrabenhenrichTrendelenburgBellachetal.2020, author = {Grabenhenrich, Linus and Trendelenburg, Val{\´e}rie and Bellach, Johanna and Y{\"u}rek, Song{\"u}l and Reich, Andreas and Fiandor, Ana and Rivero, Daniela and Sigurdardottir, Sigurveig and Clausen, Michael and Papadopoulos, Nikolaos G. and Xepapadaki, Paraskevi and Sprikkelman, Aline B. and Dontje, Bianca and Roberts, Graham and Grimshaw, Kate and Kowalski, Marek L. and Kurowski, Marcin and Dubakiene, Ruta and Rudzeviciene, Odilija and Fern{\´a}ndez-Rivas, Montserrat and Couch, Philip and Versteeg, Serge A. and van Ree, Ronald and Mills, Clare and Keil, Thomas and Beyer, Kirsten}, title = {Frequency of food allergy in school-aged children in eight European countries—The EuroPrevall-iFAAM birth cohort}, series = {Allergy}, volume = {75}, journal = {Allergy}, number = {9}, doi = {10.1111/all.14290}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-214746}, pages = {2294 -- 2308}, year = {2020}, abstract = {Background The prevalence of food allergy (FA) among European school children is poorly defined. Estimates have commonly been based on parent-reported symptoms. We aimed to estimate the frequency of FA and sensitization against food allergens in primary school children in eight European countries. Methods A follow-up assessment at age 6-10 years of a multicentre European birth cohort based was undertaken using an online parental questionnaire, clinical visits including structured interviews and skin prick tests (SPT). Children with suspected FA were scheduled for double-blind, placebo-controlled oral food challenges (DBPCFC). Results A total of 6105 children participated in this school-age follow-up (57.8\% of 10 563 recruited at birth). For 982 of 6069 children (16.2\%), parents reported adverse reactions after food consumption in the online questionnaire. Of 2288 children with parental face-to-face interviews and/or skin prick testing, 238 (10.4\%) were eligible for a DBPCFC. Sixty-three foods were challenge-tested in 46 children. Twenty food challenges were positive in 17 children, including seven to hazelnut and three to peanut. Another seventy-one children were estimated to suffer FA among those who were eligible but refused DBPCFC. This yielded prevalence estimates for FA in school age between 1.4\% (88 related to all 6105 participants of this follow-up) and 3.8\% (88 related to 2289 with completed eligibility assessment). Interpretation In primary school children in eight European countries, the prevalence of FA was lower than expected even though parents of this cohort have become especially aware of allergic reactions to food. There was moderate variation between centres hampering valid regional comparisons.}, language = {en} } @article{BousquetAntoAkdisetal.2016, author = {Bousquet, J. and Anto, J.

MeDALL has linked epidemiological, clinical and basic research using a stepwise, large-scale and integrative approach: MeDALL data of precisely phenotyped children followed in 14 birth cohorts spread across Europe were combined with systems biology (omics, IgE measurement using microarrays) and environmental data. Multimorbidity in the same child is more common than expected by chance alone, suggesting that these diseases share causal mechanisms irrespective of IgE sensitization. IgE sensitization should be considered differently in monosensitized and polysensitized individuals. Allergic multimorbidities and IgE polysensitization are often associated with the persistence or severity of allergic diseases. Environmental exposures are relevant for the development of allergy-related diseases. To complement the population-based studies in children, MeDALL included mechanistic experimental animal studies and in vitro studies in humans. The integration of multimorbidities and polysensitization has resulted in a new classification framework of allergic diseases that could help to improve the understanding of genetic and epigenetic mechanisms of allergy as well as to better manage allergic diseases. Ethics and gender were considered. MeDALL has deployed translational activities within the EU agenda.}, language = {en} }
