Clinical value of common allergens in children with bronchial asthma in Jiading area of Shanghai

Objective To investigate the common allergens and the relationship between the common allergens and the age of children with bronchial asthma in Jiading area of Shanghai. Methods Skin prick test (SPT) of 15 common allergens with standard prick liquid were performed in 351 asthmatic children, the children were divided into ≤3 years group, 3 ～6 years group and ＞6 years group, and we observed the positive rates and allergens in different age groups. Results (1) The positive rate of SPT for inhalant allergens in children with bronchial asthma is 71. 2%, specifically are: dust mite (49. 6%), house dust mite (49. 0%), fungi Ⅰ (36. 8%), mold Ⅱ (34. 8%), tree Ⅰ (32. 5%), dog epithelium (31.9%), cat epithelium (31.3%), pollen (29. 1%), tree Ⅱ (28. 8%), and feather (27.4%).

(3) The positive rate of inhalant allergens was significantly higher than food allergens.
