The review presents a modern view on the problem of the impact of smoking on allergic respiratory diseases. Smoking is known to be a significant risk factor for asthma. Currently, it is of scientific interest to study the effect of smoking on allergic rhinitis and sensitization to allergens. Tobacco smoke affects the mucous membranes of the respiratory tract, contributing to a change in structure and dysfunction, and when exposed to allergens simultaneously, it can increase the activation of the Th2-immune response, increase the production of IgE, which may contribute to the development of allergic diseases. In recent years, e-cigarette smoking has become especially popular. The aerosol components of electronic cigarettes are characterized by irritant properties and inhalation toxicity. Smoking electronic cigarettes, like smoking traditional cigarettes, can affect the immunity of the respiratory mucosa, including the functions of epithelial cells, macrophages and neutrophils. The article presents conflicting data on the effect of smoking on sensitization to allergens. Tobacco smoke is a known trigger and exposure to it increases the risk of developing new cases of asthma in patients with allergic rhinitis. The influence of smoking on the development and clinical course of allergic pathology requires further study.
Aim. To analyze the regularities of the prevalence of allergic diseases in patients of different age groups. Materials and methods. Epidemiological indices of allergic diseases were studied in children, adolescents, adults and elderly persons using official statistical data. Results. The general and primary morbidity, allergopathology structure and its dynamics were evaluated in patients of different age groups. The data, obtained in Perm Krai and the Russian Federation, were compared. Conclusions. The level of atopic dermatitis (AD) is the highest in children, allergic rhinitis (AR) – in adolescents, bronchial asthma (BA) – in adolescents and elderly persons. The cases of BA prevail in the structure of allergopathology in all age groups, besides children. Among children AD cases make 50.5 % of all allergic diseases. In dynamics, AD has a tendency to reduction of general morbidity in all age groups, BA – in children; a tendency to elevation is typical for AR in children and adolescents, BA – in adolescents, adults and elderly persons.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
