On the basis of the radioallergosorbent test (RAST) the frequency of inhalatory allergens in the etiology of bronchial asthma was studied in 189 patients. In the studied population allergy to house dust was most frequent, followed by pollens of grass and trees and less frequently by epidermis of domestic animals. In 1/3 of the patients combined allergy to house dust components and pollens was demonstrated. The predominating allergizing component of house dust is the mite, while the participation of epidermis of domestic animals was found in only 15% of the cases. In the subgroup of epidermal allergens cat epidermis prevailed (90%) and in about 1/4 of the cases it shared the role of allergen with dog epidermis. In the group of pollen allergens grass pollens predominated (94%), while in 1/3 of the cases they shared the role of allergens with tree pollens. The results confirm the high usefulness of radioimmunoassay in the diagnosis of inhalatory allergy in patients with bronchial asthma. The frequency of combined allergy to different groups of allergens was also shown.
