Dermatite atopique de l'enfant et allergie au blé

Wheat allergy amounts to 14-18% during atopic dermatitis, is often manifested by delayed reactions, either on the skin or in the digestive tract. Negative skin prick tests and specific IgE do not rule out the diagnosis. Patch testing seems to be more adapted to this food, but its specificity is low in the young infant. Diagnosis requires an elimination-provocation test, the latter being carried out on several days due to the frequency of delayed reactions.
