    Abstract:
    Objective:To investigate the allergen characteristics, allergen distribution and clinical symptoms of autumn allergic rhinitis in Changchun and surrounding areas. Methods:The allergen test results of 1080 allergic rhinitis（AR） suspected patients from Changchun and surrounding areas were collected, from August to October 2019 and August to October 2020 in the Department of Otorhinolaryngology Head and Neck Surgery, the Second Hospital of Jilin University. The positive rates of major allergens and their differences in gender, age, different years and clinical symptom were compared and analyzed. Results:①Among the 1080 suspected AR patients, 804 patients（74.44%） had positive allergens. ②The top 3 allergens of autumn AR in Changchun and surrounding areas were Artemisia（36.20%）, Dwarf ragweed（33.24%） and Candida/Penicillium notarum/Cladosporium/Alternaria/Aspergillus niger（19.81%）. The positive rates of Artemisia and Dwarf ragweed were higher in men than in women（P<0.05）. ③Artemisia was the major allergen of autumn AR in juvenile group, youth group and middle-aged group. ④The positive rate of two or more allergens was 2.39 times that of single allergen. ⑤Patients with positive autumn pollen allergens had more severe symptoms of nasal congestion, red eye/eye itching and epiphora than those in other groups. Conclusion:Seasonal AR had typical clinical symptom characteristics. Major allergens in autumn AR in Changchun and surrounding areas are autumn pollen allergens（Artemisia, Dwarf ragweed, Humulus）. The distribution of those allergens was different in gender, age, and different years. 目的：探讨长春及周边地区秋季变应性鼻炎（AR）变应原特征、分布情况及临床症状特点。 方法：记录2019年8—10月及2020年8—10月就诊于吉林大学第二医院耳鼻咽喉头颈外科的1080例来自于长春及周边地区的AR疑似患者的变应原检测结果，对比分析主要变应原的阳性率及其在性别、年龄、不同年份、临床症状之间的差异。 结果：①1080例就诊的AR疑似患者中，变应原阳性患者共804例（74.44%）。②长春及其周边地区秋季前3位变应原为蒿（36.20%）、矮豚草（33.24%）、念珠菌/点青霉/分枝孢霉/交链孢霉/黑曲霉（19.81%）。蒿与矮豚草的阳性率男性高于女性（P<0.05）。③蒿是少年组、青年组、中年组秋季AR最主要的变应原。④2种及2种以上变应原阳性率为单一变应原阳性率的2.39倍。⑤秋季花粉变应原阳性患者的鼻塞、眼红/痒、溢泪三个症状相比其他组患者更严重。 结论：季节性AR有典型临床症状特点。长春及其周边地区秋季AR以秋季花粉变应原（蒿、矮豚草、葎草）阳性为主，变应原分布在性别、年龄、不同年份之间存在差异。.
