[Variants of immune response in children with acute respiratory viral infections].
Four patterns of changes in the proliferative activity of T-lymphocytes in the lymphocyte blastogenesis test with phytohemagglutinin (PHA) are distinguished in children with acute respiratory viral infections (ARVI). The differences between these patterns are due to aggravated clinical severity of the infection process and enhancement of the cytokine reaction of macrophage monocytes. Comparison of immunological characteristics of response to ARVI in 4 groups of children showed that high reactivity of T-lymphocytes during the acute phase of disease (first and third variants) correlated with a relatively weak production of immunoglobulins and antiviral antibodies, while the suppression of T-lymphocyte response to PHA (second and fourth variants) is associated with expressed humoral profile of immune response by the level of immunoglobulin and antiviral antibody production. These data permit a hypothesis about the predominant generation of T x 1-like clones in children with the first and third variants of immune response and of T x 2-like clones in children with the second and fourth variants.
