Analysis of sensitization characteristics of Artemisia pollen in autumn allergic rhinitis in the Changchun area of China
Objective To analyze the relationship between Artemisia pollen concentrations in autumn and the number of visits for aller-gic rhinitis,and the sensitization characteristics of Artemisia pollen in the Changchun area(Jilin,China).Methods From August 1 to October 31,2022,the concentration of airborne Artemisia pollen was determined,in addition to the number of outpatient visits to the Department of Otorhinolaryngology,Head and Neck Surgery of the Second Hospital of Jilin University,and the number of pa-tients diagnosed with allergic rhinitis.A total of 1,945 patients from the Changchun area underwent allergen testing in the autumn(August 1 to October 31)of 2019 to 2022,and 1,506 were positive for ≥ 1 allergens by serology-specific immunoglobulin E(IgE)testing.The relationship between Artemisia pollen concentration and the number of consultations for allergic rhinitis and the main sensitizing characteristics of Artemisia pollen in this area were analyzed.Furthermore,sensitization to Artemisia pollen was compared between different age groups,sexes,and mono-sensitization and multiple-sensitization.Results The concentration of Artemisia pollen increased from August to September,and was positively correlated with the number of visits for allergic rhinitis(rs=0.751,P＜0.01).Serological-specific IgE testing revealed that Artemisia pollen positivity reached 44.6％.The positivity rate for Artemisia pollen differed among various age groups(x2=4.377,P＜0.05).Artemisia pollen sensitization was more prone to multiple sensitization,and mainly associated with ragweed(58.8％).Conclusion The concentration of Artemisia pollen in autumn was consistent with the peak for visits for allergic rhinitis in the Changchun area.Artemisia pollen was the primary allergen in autumn among patients with allergic rhinitis,and tended to be multiple allergens.
