Skin prick tests with 53 inhalant and 46 food allergens were performed in 812 patients(bronchial asthrna. 342, allergic rhinitis. 166, combined: 158, urticaria ' 127, atopic dermatitis.' 19) and the level of total IgE were evaluated in 683 patients(br...
Skin prick tests with 53 inhalant and 46 food allergens were performed in 812 patients(bronchial asthrna. 342, allergic rhinitis. 166, combined: 158, urticaria ' 127, atopic dermatitis.' 19) and the level of total IgE were evaluated in 683 patients(bronchial asthma. 293, allergic rhinitis. 135, combined: 140, urticaria 105, atopic dermatitis. 10) at the Allergy Clinic of Severance Hospital in Yonsei University College of Medicine. The following results were obtained. 1) 578 patients(71.7%) showed positive reactions (erythema 21mm) to one or more inhalant allergens, 234 patients(28.8%) showed negative reactions to all inhalant allegens and 347 patients (42.8%) showed positive reactions to one or more food allergens. 2) House dust mite antigens brought positive reactions in 44.9% of total patients, house dust in 42%, insects in 32% animal epithelials in 32.0%, weed pollens in 25.3%, molds in 19.5%, grass pollens in 13.2%, tree pollens in 11.6% and bacteria in 5.8%. 3) Dermatophagoides farinae antigen was the most frequent allergen showing positive results on skin prick tests, followed by house dust, threshing mixture, Dermatophagoides pteronyssinus, cat fur, household insect and so on. 4) There was a significant difference in the level of total IgE between positive and negative skin test groups.(p<0.001) 5) The levelsof total IgE in patients with positive response to both house dust mite and pollen were significantly higher than those of positive responders to house dust mite or pollen alone.
