Abstract:
PURPOSE: Atopic dermatitis (AD) is the allergic disease which appears during infancy. This study aimed to find associations between clinical parameters, allergen sensitization and severity of AD in chidren under 2 years. METHODS: Two hundred fifteen patients (123 boys, 92 girls) under 2 years with severe AD who visited the department of pediatrics of Hangang Sacred Heart Hospital and Asan Medical Center were enrolled. We checked the severity scoring of atopic dermatitis (SCORAD), total eosinophil count, eosinophil ratio, eosionphil cationic protein (ECP), total IgE and specific IgE to 12 allergens [egg white, milk, soybean, peanut, wheat, fish, Dermatophagoides pteronyssinus (D.p), Dermatophagoides farinae (D.f), dog, cat, cockroach, alternaria]. Atopic AD was defined as serum total IgE 200 IU/mL or specific IgE positive. RESULTS: The mean of SCORAD was 69.0. Atopic AD was 161 (75%). There were no differences in age between atopic and non-atopic AD. However, SCORAD, IgE, eosinophil, and ECP were the higher in atopic AD. Sensitization to food allergen was the highest in egg white (76.4%), followed by milk (58.4%) and aeroallergens such as D.f (49.1%) and D.p (46.6%). The more the number of sensitized food allergens, the higher the SCORAD appeared. However, it did not show any relationships with the number of sensitized aeroallergens. CONCLUSION: The percentage and severity were higher in atopic AD than non-atopic AD. The number of sensitized to food allergen affect the severity. Therefore, understanding the sensitization to food allergens may be more helpful in predicting severity than sensitization to aeroallergen. In cases of positive reaction to aeroallergens, it is necessary to observe the development of respiratory allergic disease.
