[Anti-somatostatin autoantibodies in the blood serum of patients with schizophrenia].

: Solid-phase IEA was used to measure the level of autoantibodies to somatostatin in the blood serum of 44 schizophrenics and 24 healthy donors. The patients suffering from schizophrenia manifested a higher (p less than 0.01) level of immune responsiveness of the blood serum to somatostatin (0.665 +/- 0.03) as compared to the control group (0.509 +/- 0.05). The main contribution to the differences between the groups as regards the parameter measured is made by patients with malignant (0.810 +/- 0.10) and paranoid (0.773 +/- 0.08) schizophrenia whereas the patients' subgroup with slow-progressive schizophrenia did not differ from normal regarding the level of autoantibodies to somatostatin in the serum (0.504 +/- 0.03). These tentative data agree with a hypothesis of the involvement of autoimmune processes into the development of schizophrenia.
