Their prevalence and levels have been so far cross‐sectionally examined among adult allergic patients and much less is known about their origins and relevance in childhood.MethodsWe examined CCD with a cross‐sectional approach in 1263 Italian pollen allergic children (Panallergen in Paediatrics, PAN‐PED), as well as with a longitudinal approach in 612 German children (Multicenter Allergy Study, MAS), whose cutaneous and IgE sensitization profile to a broad panel of allergen extracts and molecules was already known. The presence and levels of IgE to CCD were examined in the sera of both cohorts using bromelain (MUXF3) as reagent and a novel chemiluminescence detection system, operating in a solid phase of fluorescently labelled and streptavidin‐coated paramagnetic microparticles (NOVEOS, HYCOR, USA).ResultsIgE to CCD was found in 22% of the Italian pollen allergic children, mainly in association with an IgE response to grass pollen. Children with IgE to CCD had higher total IgE levels and were sensitized to more allergenic molecules of Phleum pratense than those with no IgE to CCD. Among participants of the German MAS birth cohort study, IgE to CCD emerged early in life (even at pre‐school age), with IgE sensitization to group 1 and 4 allergen molecules of grasses, and almost invariably persisted over the full observation period.ConclusionsOur results contribute to dissect the immunological origins, onset, evolution and risk factors of CCD‐sIgE response in childhood, and raise the hypothesis that group 1 and/or 4 allergen molecules of grass pollen are major inducers of these antibodies through an antigen‐specific, T‐B cell cognate interaction. 10.1111/cea.14439 http://creativecommons.org/licenses/by-nc-nd/4.0/ |
