[Specific IgE against inhaled allergens in dystreptic children with food allergy].
Immunoglobulin E specific for the selected inhalator allergens have been determined in 42 children with food allergy and failure to thrive, using tests and equipment 3M (Bio Whittaker). Co-existence of food allergy with hypersensitivity to inhaled allergens have been confirmed in 41 children (41%). An equivalent expression grade of IgE antibodies against food and inhaled antigens has usually been noted. Specific IgE produced in response to house dust and mixed feathers have been seen most frequently, and the first have been found in 37% of the tested children in the concentration exceeding 1.0 Ul/ml (2nd, 3rd and 4th class). The obtained results confirmed that specific IgE antibodies against inhaled allergens are being present in children who fail to grow and suffer from the food allergy. These findings should advocate further investigations in specific IgE antibodies to other groups of allergens.
