RESUMO
Objective: To analyze the characteristics of allergen spectrum in patients with allergic rhinitis (AR) in Xinjiang area in recent 13 years. Methods: The skin prick test (SPT) results of 5 019 AR patients from 2007 to 2019 were retrospectively summarized, and 14 allergens of different age, gender and race were analyzed. Results: The distribution of 14 allergens was significantly different in different years, the difference was significant (P<0.05). The top three positive rates of 14 allergens were quinoa 48.2% (2 398/4 970), plantain 33.3% (1 221/3 667), and Artemisia 33.1% (1 647/4 974). There was no significant difference in the positive rate of dog epithelium between different genders and ages (χ²=0.041, P>0.05; χ²=3.8, P>0.05), the difference of other allergen in positive rates was statistically significant (all P<0.05). The positive rates of Alternaria Alternata (χ²=7.3), Penicillium Sp. (χ²=0.3), Cat Epithelium (χ²=3.1), Dust Mite (χ²=1.4), Acaroid Mite (χ²=0.5) and Cockroach (χ²=2.9) had no significant difference among different races (all P>0.05). The positive rates of other eight allergens including Artemisia Vulgaris (χ²=64.9), Chenopodium (χ²=204.1), Artemisiifolia (χ²=72.4), Plantain (χ²=87.8), Phleum Pratense L(χ²=55.4), Robinia Pseudoacacia (χ²=67.8), Canis Familiari (χ²=70.8), Dog Epithelium (χ²=15.7) were significantly different among different races (all P<0.05). Conclusion: The distribution of allergens in Xinjiang area changes with time, the main allergens are mainly herbaceous, and the distribution of allergens in patients with AR is different in gender, age and race.
