[Allergologic study of the pathogenesis of atopic dermatitis in infancy and childhood].

The authors present the results of allergologic investigations in 54 infants and children with atopic dermatitis. To demonstrate the food and inhalative allergies, which are most important etiologic factors in this disease, different methods have been administered. Besides these in vitro and in vivo methods oral food challenges were done to verify the real causative role of the food in question. Food allergy only was verified in 16 cases, 12 patients were suffering in inhalative allergy. Both kind of allergens produced reaction in 19 cases. Among the foods hen egg caused sensibilization most frequently, among the inhalants the house dust mite. In analysing the results the authors want to demonstrate the combined allergic etiology, of atopic dermatitis.
