Allergic investigations in children with atopic eczema.

In the study the results of allergic investigations in 36 children with atopic eczema were demonstrated. Prick testing with 22 allergens made by Bencard and 5 natural allergens showed an allergic reaction in 28 children (77.8%). The positive reaction was noted more often in children with a generalized form of disease compared to a limited one (81.85 and 76.0% respectively). Allergy to inhalatory allergens was observed in 72.2%, to food allergens in 38.9% and to other allergens in 27.8% of patients. Among inhalatory allergens, sensitivity to domestic dust (55.6%), inhalatory allergens A1 and grass pollen (both 50.0%) and Dermatophagoides pt. (44.4%) were most common. Food allergens were represented by grain (16.7%), uncooked milk and chocolate (both 11.1%). The conducted investigations indicate, that uncooked or cooked milk and milk cream seem to be more accurate indicators of milk sensitivity than milk allergen by Bencard.
