Disagreement between skin prick tests and specific IgE in early childhood


Chauveau, Amandine; Dalphin, Marie-Laure; Kaulek, Vincent; Roduit, Caroline; Pugin, Aurore; von Mutius, Erika; Vuitton, Dominique Angèle; Dalphin, Jean-Charles (2016). Disagreement between skin prick tests and specific IgE in early childhood. International Archives of Allergy and Immunology, 170(2):69-74.

Abstract

BACKGROUND: Accurate diagnosis of allergic sensitization is essential in clinical practice and allergy research, and the choice of assessment method may have an important impact. The PASTURE study (Protection against Allergy: Study of Rural Environment) examines the influence of exposure to a dairy farm environment on the occurrence of allergy in a cohort of rural European children from birth to 10 years. The aim of our study was to analyze agreement between skin prick tests (SPTs), to aeroallergens and food allergens, and specific IgE and to evaluate the association of SPT with atopic dermatitis in the 204 French children of the PASTURE study.
METHODS: SPT, atopic dermatitis assessment, and specific IgE measurements were performed at 1, 4.5, and 6 years.
RESULTS: A total of 137 children attended all three visits. The agreement between SPTs and specific IgE was poor except for perennial aeroallergens at 6 years and for an IgE cutoff greater than 0.7 IU/ml (κ = 0.69, 0.5202 - 0.8621). The prevalence of positive SPTs increased with age. Positive SPTs were transient at 1 year, whereas they were persistent between 4.5 and 6 years. Positive SPTs at 1 year were predictive of the occurrence of atopic dermatitis during follow-up.
CONCLUSION: SPTs did not have good agreement with serum-specific IgE in early childhood. Both tests (SPT and specific IgE) should be used. Skin allergenic reactivity increased with age and was transient at 1 year but associated with the occurrence of atopic dermatitis.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
