Abstract

Objective:To analyze the distribution characteristics of common aeroallergens in patients with allergic rhinitis(AR)in Wuhan. Method:Serum specific IgE(ssIgE)was detected in 1 983 patients with clinically diagnosed AR by Midiwiss Allergen Screen system. Data was analyzed statistically. Result:Among the 1 983 patients,1 507(76.0%)had at least one positive ssIgE. The most common aeroallergens were Dermatophagoides pteronyssinus(62.0%),mixed fungi(32.1%)and house dust(27.3%).Single positive allergen(43.8%),dual positive allergen(28.1%)and triple positive allergen(15.4%)were the most common combinations. The proportion of single positive allergens in the juvenile group(1 to 17 years old)(35.2%)was lower than adult group(≥18 years old)(46.7%),while the proportion of multiple positive allergens was higher than adult group. The positive rates of mulberry and mixed grass in male group were higher than female group. The positive rates of house dust,cat fur and dog fur in the juvenile group were higher than the adult group,while the positive rate of mulberry,cockroach and mixed grass were lower than the adult group. In the elder group(60-88 years old),the positive rates of Dermatophagoides pteronyssinus and mixed fungi were higher than the other three groups. The positive rates of Dermatophagoides pteronyssinus in summer and autumn were higher than that in winter and spring. The positive rate of mixed grass in autumn was much higher and the positive rate of mixed trees and mulberry trees in spring was higher than summer and autumn. Conclusion:Dermatophagoides pteronyssinus,mixed fungi and house dust were the most common aeroallergens among patients with allergic rhinitis in Wuhan. The distribution characteristics in different genders,ages and seasons were different..
