[Immunological reactions in different forms of mental disorders].

State of innate and adaptive immunity has been assessed by the indices of activity of leukocyte elastase, alpha1-proteinase inhibitor (alpha(1)-PI), level of C-reactive protein and autoantibodies to neuroantigens (nerve growth factor and basic myelin protein) in different forms of mentalopathology: schizophrenia-spectrum disorders, mental retardation with behavioral abnormalities, organic mental disorders, affective disorders, psychogenias (adaptation disorders), early alcoholism. The increase of activity or levels of all immunological parameters was characteristic of these diseases. However within each group were patients with different levels of immunity activation. A number of patients with significant immunity activation was higher in the groups of schizophrenia-spectrum disorders, early alcoholism, organic mental disorders, mental retardation with behavioral abnormalities and affective disorders. The lowest frequency of such cases was observed for psychogenias (adaptation disorders). These results give grounds to suggest that the extent of immunity activation depends as on severity of psychopathogy as well on individual peculiarities of immunological reactivity in response to a brain pathological process.
