Context Food allergy plays a significant pathogenic role among children with atopic dermatitis (AD). Objective The aims of this study were to evaluate allergy to egg in these children and determine the egg specific immunoglobulin E (IgE) cutoff point. Design and Setting It was a cross-sectional study that took place at Immunology, Asthma and Allergy Research Institute from 2005 to 2007. Methods Children younger than 14 years old with AD entered the study. Careful medical histories were taken and skin prick and Immuno-CAP tests with the most commonly offending foods (cow's milk, egg, wheat, peanut, and soy) were performed. Children with a clear, positive history of food allergy and a positive IgE-mediated test or those with positive responses to both IgE-mediated tests were determined to have food allergies. The egg-specific IgE level cutoff point was determined. Results A hundred patients entered the study (from 2 months to 12 years old). They were divided into 3 age groups: first Conclusion Prevalence of egg allergy is highly significant in patients with AD.To use egg-specific IgE level cutoff point, the patient population under study must be considered.
