Jie Zhong, Da-Bo Liu, Zhen-Yun Huang and Jian-Wen Zhong

This retrospective study reviewed skin prick test (SPT) positive results to various aeroallergens among 2136 children with allergic rhinitis (AR) in Guangzhou City, Southern China. Most (74.67%) of the 2136 children who underwent skin test showed positive reaction to 2-4 allergens. The allergen group with the highest positive incidence was Dermatophagoides pteronyssinus (der.p.) at 93.16%, followed by Dermatophagoides farinae (der.f.) at 86.23%, Tropical mites at 40.73%, Cat hair at 20.32% and Blattella germanica at 19.62%. Dust mites (der.p. & der.f) yielded strong positive reaction trend on AR children. The positive rate of der.p.,Cat hair and Blattella germanica was higher in school children group than preschool children group. Except for Blattella germanica, sensitization to every tested allergen varied in four season groups. These allergens should be given the highest priority when making the allergen avoidance strategies for AR children.
