Dermatite atopique et allergie alimentaire chez l'enfant

Food allergy is known to provoke flares of atopic dermatitis (AD). The prevalence of food allergy in infants with atopic dermatis has been estimated to be 40%. Atopy patch testing is a novel approach to diagnose food-induced AD, but standardization of atopy patch test extracts needs addional studies. Oral food challenge is the gold standard for diagnose of food allergy. Nevertheless, the method used for oral food challenges in cases of late eczematous reactions remains to be defined. Food appears to aggrevate eczematous lesions in young children, and it is recognized that allergy testing needs to be standardized in order to prove that relationship.
