The house dust mites significance in the development of atopy

Abstract

Background. Knowledge of the structure and particularity of sensitization in the region allows us to choose the correct tactics of treatment and prevention of atopic reactions. Objective. To study the structure of sensitization to inhalation allergens in Moscow and Moscow region since 2009 to 2017 and to determine significance of sensitization to house dust mites Dermatophagoides pteronyssinus (Der p) and Dermatophagoides farinae (Der f) in it. Methods. Blood serum of Moscow region patients with atopy (n=2546) was examined by RIDA AllergyScreen method in the period from 2009 to 2017. Results. The allergosensitisation structure was determined. It was revealed that there was no decreasing of the frequency of house dust mites (Der р and Der f) sensitization in observation period. The features of monovalent, polyvalent and combined sensitization among patients with IgE reactions to Der р and Der f were analyzed. Conclusions. According to our research 20% of patients with atopy in Moscow region have sensitization to Der р and/or Der f. The percentage of allergosensitisation to Der р is higher than to Der f. Most often house dust mites sensitization combined with pollen sensitization.
