Allergic rhinitis in Samara: clinical and allergological aspects

The aim of the study was to study the dynamics of clinical and allergic characteristics of patients with allergic rhinitis (AR) in Samara over the past 5 years. Clinical and allergological examination was performed in 1526 patients from 2012 to 2018. For skin prick testing, 16 names of standard allergens were used. In 2018, the most common forms of AR were seasonal - 40.7 % and combined (seasonal and perennial) forms of AR - 39.8 %. Over the past 5 years, there has been a 1.5-fold increase in seasonal forms of AR (pollinosis). The structure of sensitization revealed an increase in pollen allergy from 39.2 % to 50.6 %, and a decrease in the level of hypersensitivity to epidermal allergens from 29.9 % to 14.5 %. Sensitization to weeds remains dominant in patients with pollinosis and ranges from 82.8 % to 75.2 % in 2012 and 2018, respectively. The predominance of polysensitization to different groups of allergens over monosensitization remains: 55.8 % and 44.2 %, respectively.
