... ess opharmacotherapy of allergic rhinitis with antihistamines. Material and methods. The study included 118 patients with allergic rhinitis. In 112 patients, seasonal allergic rhinitis was diagnosed with an exacerbation in summer (94.9%) and in the spring-summer period of pallination (82.2%). The control group included 200 practically healthy individuals. Genotyping of the IL17A rs2275913 polymorphism was performed using the real-time polymerase chain reaction (Real-Time) "SNP-EXPRESS"-RV method. Results. Patients with allergic rhinitis complained of seasonal and year-round symptoms, which included rhinorrhea, nasal obstruction, sneezing, itching, burning sensation in the nose, sniffling, snoring, apnea, voice change and nasality.
