Abstract:
Interleukines (IL) levels, mononuclear phagocytes (MP) activity and proliferative T-lymphocytes activity were studied in 6 patients with paranoid (ICD-10 item F20.00) and 20 patients with shift-like (F20.01) types of schizophrenia. Significant (p < 0.05) decrease of MP activity, monocytes-stimulated IL-1 beta production (mostly pronounced in paranoid type) lymphocyte-stimulated IL-2 production (p < 0.05) and proliferate T-lymphocytes activity (p < 0.01) were characteristic of schizophrenia in use of low mitogen doses. A significant increase (p < 0.001) of IL-2 serum concentration was found only in shift-like type. The changes of IL-2 concentration are more frequent in younger patients, aged up to 30 years, with relatively long duration of illness and manifestation stage (over 5 years). An increase of serum IL-2 in the patients was not connected with the changes of soluble IL-2 receptors in the serum as it did not differ from the control values.
