Egg allergy in atopic dermatitis patients-analysis of results of specific extract IgE and specific IgE to molecular components. Bird-egg syndrome

Abstract

Aim: To evaluate the occurrence of egg allergy in atopic dermatitis patients, to analyse the results of specific IgE. We show the occurrence of bird-egg syndrome and the relation between the sensitisation to some molecular components and egg allergy. Methods: Egg allergy was confirmed according to the results of the challenge test (history) together with positive results of specific IgE to molecular components of egg and/or extract specific IgE to egg. Results and conclusion: Altogether 100 atopic dermatitis patients were examined – 48 men, 52 women, the average age 40.9 years. Reaction to egg was confirmed in 23 patients (23%); egg allergy was confirmed in 18 patients (18%). In these patients we recorded the significantly higher sensitisation to molecular components Der f 2, Der p 2, Equ c 1 and Phl p 7. The bird – egg syndrome was confirmed in 3 patients (3%).
