Abstract:
OBJECTIVE:To investigate which aeroallergens were prevalent in patients with allergic rhinitis in Yunnan.
METHOD:Retrospective analysis of the medical records of intradermal test performed in 1893 AR patients. The samples were divided into four age groups: 4-17-year-olds, > 17-35-year-olds, > 35-50-year-olds and > 50-70-year-olds. According to gender,the samples were decided into two groups: the males and the females. The positive rate of aeroallergens were compared among the groups.
RESULT:(1)The total positive rate of intradermal test was 70.1%. The top ten allergens were as follow: dermatophagoides pteronyssinus, dermatophagoides farina, house dust, pollen of the summer and autumn, alnus nepalensis, chenopodiaceae, mugwort, poaceae, brassica and cockroach. (2) In all groups,patients with triple positive allergens were the most common,followed by dual positive allergens and single positive allergen. (3) Among the top ten allergens, the top three positive ones in all groups were dermatophagoides pteronyssinus, dermatophagoides farina and house dust. And there were significant differences between 4-17-year-olds group and the other age groups (P < 0.01). (4) There was no significant difference between male and female patients in distribution of aeroallergens except House dust and mite.
CONCLUSION:The most common allergen in patients with allergic rhinitis in Yunnan is mite,the follow are pollen of the summer and autumn, alnus nepalensis, chenopodiaceae, mugwort, poaceae, and brassica. The distribution of aeroallergens are different among the age groups, but has no evident correlation with gender.
