Abstract:
Objective To analyze the distribution of allergens in allergic rhinitis (AR) patients and the correlation between the incidence of allergic rhinitis and seasonal climate in Ankang area of Shaanxi Province, and to provide a theoretical basis for the prevention and treatment of AR. Methods A total of 567 AR patients admitted to the Department of Otolaryngology, Ankang Central Hospital from January 2019 to January 2020 were investigated by multi-stage stratified random method. Five mL elbow venous blood were extracted from AR patients, and the supernatants were collected after centrifugation. Allergen specific IgE antibodies were determined by ELISA. Allergens tested included 15 inhalation allergens and 20 ingestion allergens. The number of AR patients per month was counted, and the average air pressure (Hpa), average temperature (℃), average rainfall (mm) and average wind speed (m/s) were recorded during the same period. Pearson correlation analysis was used to analyze the correlation between single climate factor and the incidence of AR. Results Among the 567 AR patients, inhaled allergens were mainly dust mites in 357 cases (62.96%), cat hair in 75 cases (13.23%), mugwort in 37 cases (6.53%), cockroaches in 29 cases (5.11%), and house dust in 26 cases (4.59%); ingestion allergens were mainly shrimp in 49 cases (8.64%), mutton in 36 cases (6.35%), marine fish in 32 cases (5.64%), and soybean in 26 cases (4.59%). There were statistically significant differences in cat hair and mugwort among different ages (P<0.05). The incidence of AR patients in Ankang area of Shaanxi Province was mainly concentrated in summer (32.98%) and autumn (46.38%), and there was statistical significance between mugwort and house dust in different seasons (P<0.05). The number of AR cases was positively correlated with average temperature and rainfall (r=0.481, 0.671, P<0.05). It was negatively correlated with average wind speed and average air pressure (r=-0.413, -0.549, P<0.05). Conclusion Dust mites are the most common allergen in AR patients in Ankang area of Shaanxi Province. The incidence of AR mainly occurs in summer and autumn, which has a certain correlation with the seasonal climate in Ankang area.
