Background. The aim of this study was to estimate the prevalence rate of severe allergic reactions to hymenoptera sting according to data, gathered by specialized allergological department of Kazan hospital No. 7 in 2000–2011.

Materials and Methods. 493 patients hospitalized during the period of 2000–2011 with anaphylactic shock (ASh) including 133 patients with ASh to Hymenoptera sting were analised.

Results. The study showed a high frequency of ASh developed as a result of hymenoptera sting comparing with total cases of ASh hospitalizations (27%, Cl: 23–31%). In most ASh cases was caused by wasps stings (52%, Cl: 43–60%). Male patients are supposed to be more vulnerable to the risk of stings (58%, Cl: 50–66%). More often ASh showed acute cardiovascular symptoms (79,7%, Cl: 72–85%). Emergency crews used epinefrine in order to relieve ASh only in 30% of cases (30%, Cl: 22–38%).

Conclusion. Systemic allergic reactions to Hymenoptera sting prevalence shows the need for registration of allergens for immunotherapy and injection  pen with epinefrine for self help in case of ASh development with in the territory of Russian Federation.
