ABSTRACT
Objective To analyze the epidemiological characteristics of AR and its correlation with serum IFN-γ and IL-4 levels in Bazhong City, and to provide theoretical basis for clinical prevention and treatment of AR. Methods Adopt the method of multistage stratified random survey from January 2019 to January 2020 bazhong 3 armour hospital otolaryngology seeing a doctor , with face to face questionnaire survey form the people generally, AR number of statistics, the main clinical symptoms and related symptoms, AR merger disease situation, according to the illness severity was divided into mild and moderately severe group, Five mL of elbow venous blood was extracted from AR patients, and 22 kinds of allergens were determined by using the allergen-specific IgE antibody detection kit (western blot). Serum IFN-γ and IL-4 levels were determined by enzyme-linked immunosorbent assay. Pearson correlation analysis was performed on serum IFN-γ and IL-4 levels and severity of allergic rhinitis. Results Among 1 243 patients who completed the questionnaire, the prevalence of AR was 275 (22.12%). There was significant difference in the prevalence of AR among different age groups (χ2=6.809 , P2=7.914 , P<0.0) and the prevalence of AR in workers was the highest (26.48%). Among 275 AR patients in Bazhong City, 153 cases (55.64%) had seasonal allergic rhinitis and 122 cases (44.36%) had perennial allergic rhinitis. The main clinical symptoms of AR patients were sneezing in 234 cases (85.09%) and nasal obstruction in 197 cases (71.64%). AR combined with bronchial asthma in 59 cases (21.45%), conjunctivitis in 28 cases (10.18%); the peak of AR incidence was mainly in July. Among 22 allergens, dust mite was the most common allergen in 139 cases (50.55%), followed by penicillin in 56 cases (20.36%). The main inducing factors were pollen 112 cases (40.73%) and cold 98 cases (35.64%). According to the severity of the disease, they were divided into mild group (n=178) and moderate to severe group (n=97). The serum IL-4 level in moderate and severe groups was significantly higher than that in mild group (P<0.05). The serum IFN-γ level in moderate and severe groups was significantly lower than that in mild group (P<0.05). Pearson correlation analysis showed that il-4 level was positively correlated with disease severity (r=0.492, P<0.05). IFN-γ was negatively correlated with the severity of the disease (r=-0.459, P<0.05). Conclusion The prevalence of AR is high in Bazhong city, and the main clinical symptom is sneezing. Among the complications, bronchial asthma is the most common. Colds and weather changes are the main factors causing AR.
