Atopic dermatitis (AtD) - chronic inflammatory allergic dermal disease (ADs) of multifactorial pathogenesis. Most authors point out critical pathogenetic role of IgE-mediated mechanisms of hypersensitivity in relation to many food-borne, domestic and/or environmental allergens. The aim of the study was to study the cause-significant allergenic and non-allergenic triggers, prevalence and clinical features of AtD in Primorye Territory of Russia among young children (Ch) and teenagers (Tn). Researchers conducted showed wide prevalence of AtD among children in Vladivostok and Primorye Territory with high incidence rate in the last decade. The true picture of prevalence of ADs in Primorye Territory of Russia among Ch and Tn was established, clinical features and the main allergenic and non-allergenic triggers that contribute to the early development of the disease were determined. The revealed peculiarities will be promoting the timely conduct of therapeutic and preventive measures among Ch.
