Respiratory syncytial viral infection in children. Role in the structure of respiratory pathology and clinical and immunological features

Abstract

Acute respiratory infections (ARI) consistently occupy a leading place in the structure of infectious pathology, especially among children. The spectrum of pathogens is usually determined by the season and age aspect of the observed. In a large number of respiratory viruses, respiratory syncytial virus (RSV) occupies a special place due to the variety and severity of clinical manifestations of the disease caused by it in young children. This article is devoted to the analysis of the clinical course of RSV infection in children, the study of the features of the immune status against the background of this disease. It was found that in most cases of RSV infection in children was characterized by signs of bronchial obstruction syndrome and as a consequence in this group of children were found to have dysfunction of the immune system and reduction in the total number of T-lymphocytes, the hyperactivation In-cell component of adaptive immunity, manifested disimmunoglobulinemia (increase in the content of total IgE at lower IgA and IgG), that is, with the formation of immunodeficiency states from T- and B-cell links of adaptive immunity, with long-term recovery of impaired performance, even against the background of effective antiviral therapy.
