Allergen detection of chronic urticaria and analysis of desensitization treatment in Wuhan Area

Objectives:To investigate the main allergens of chronic urticaria and its desensitization treatment efficacy in Wuhan Area.Methods:150 patients participated skin tests of aeroallergens and food allergens,which 50 patients among them who were positive to aeroallergens were received specific immune desensitization treatment.Results:In the group of aeroallergens,the most high positive ratios were mosquito(71.3%),ragweed(61.3%)and dust mite(55.3%)in order,while sesame,shrimp and soybean were the most high positive ratios of food allergens.in the group of allergic to aeroallergens,total effective ratio of desensitization treatment was 76%.Conclusions:Mosquito,ragweed,dust mite are the most important three aeroallergens,While sesame,shrimp and soybean are the most important three food allergens in Wuhan area.The efficacy of specific desensitization treatment was satisfying for those chronic urticaria patients who are allergic to aeroallergens and have no other obvious etiological factors.
