Abstract
Objective To analyze and determine the common inhalant allergens and important food allergens in clinical practice. Methods Base on the allergen-specific IgE( slgE ) results detected by ImmunoCAP system in Department of Allergy, Peking Union Medical College Hospital in the past three years, the test amount, the positive results number, and the positive rate of each allergen were calculated respectively, and the sorting analysis of positive results number was performed. Results 215 210 detection were assayed in the past 3 years, 76% of them were inhalant allergens slgE, 22% were food allergens slgE, and 2% were other allergens ( including drugs and insects et al ) slgE. There were 18 kinds of common inhalant allergens, including Dermatophagoid.es pteronyssinus, Dermatophagoid.es farinae, mugwort, Japanese hop, Altermaria alternate, white ash, mountain juniper, common ragweed, common silver birch, Cockroach ( German ), maple leaf sycamore, cocklebur, hand dander, goosefoot ( Lambs quarters ), and Aspergillus fumigatus, which contributed to 95 % of inhalant allergen sigE positive results. The important food allergens were egg, milk, peanut, soybean, shrimp, crab, grain, nut and fruit. The positive slgE results number of 27 kinds ofinhalant and 42 kinds of food allergens was less then ten in the past 3 years, and no positive result was found in some of them. Phadiatop and fx5 were the most common screening tests used in clinical practice. Conclusions The variety of allergens is great, but the common inhalant and important food allergens are limited in clinical practice. Some allergens are really rare. The common inhalant and important food allergens spectrum of China is in accord with data of foreign publications.关键词
