Clinical and immunological characteristics of acute respiratory viral infections in children

The study of the dynamics of the content of immunoglobulins (Ig) in 140 children with different variants of the course of ARVI showed that the specific immune response in uncomplicated ARVI is an increased synthesis of Ig A during the recovery period. Ig G content is largely associated with the severity of the disease. With complicated ARVI, the immune response is expressed in an increase in the level of Ig G, A and M, but depends on the period of the disease and the severity of the bacterial complication. In children with a burdened premorbid background, the level of Ig G increases slightly, which is reflected in the incidence of ARVI complications in this group of children.
