Detection and Analysis of Aspiration Allergens of Children's Bronchial Asthma in Xi'an Area

Objective: To analyze the distribution of common aspiration allergens of children's bronchial asthma in xi'an area.Methods: Allergen skin prick test was performed to detect the aspiration allergens of 950 cases of children with bronchial asthma in xi 'an area, with Histamine used as positive control and physiological saline as negative control. Results: In 950 cases of children with bronchial asthma, positive skin prick test was found in 384 cases, and the positive rate was 40.4 %. No significant difference was found in the test for allergen distribution between males and females(P0.05). The Dust mites were found to be the main allergen, and the positive rate was 65.6 %, followed by mugwort and mold classes. With the increase of age, the allergen positive rate increased significantly(P0.05),and there were at least two or three positive allergens in most cases of the children with positive allergen. Conclutsion: The distribution of inhaled allergens of children's bronchial asthma in xi'an area showed no statistical correlation with gender, which was significantly correlated with age.
