ABSTRACT
OBJECTIVE@#To investigate the distribution of positive allergens in patients with allergic rhinitis in Changzhou.@*METHOD@#A total of 4242 cases with allergic symptoms and signs underwent skin prick test with 16 kinds of standardized allergens. The common allergens were found out. The samples were stratified on seven age groups to analysis the distributive characteristics of allergens responsible for each group. The samples were also stratified on children group and adults group to analysis their response degree to dust mite.@*RESULT@#2638 cases (62.19%) had the positive reaction, including male 1380 (52.3%) cases, female 1258 (47.7%) cases. Dermatophagoides farinae and dermatophagoides pteronyssinus had the highest positive ratio (85.86%, 83.55%) in inhalation group, followed cockroach (11.49%) and Humulus L. (9.82%), fungus (2.92%) in the lower positive ratio. Shrimp (5.76%) was the most common allergen in food group. The distribution of common allergens in different age groups was variable. There was significantly higher sensitivity to dust mite between children group compared to adults group (P < 0.01).@*CONCLUSION@#The study shows that Dust mite was the mostly responsible common allergen in Changzhou district. The distribution of common allergens in children group and adults group was variable.
