[Humoral and cellular immunologic reactions in various forms of chronic psychiatric diseases].

Studies on the status of the immune system in mental disorders have mostly provided contradictory results. For example, some authors have reported dramatic increases of immunoglobulin G in schizophrenic patients, and others a decrease of immunoglobulin G in the same patients. This prompted us to undertake a study on a large cohort of psychiatric patients (120 schizophrenics, 30 manic-depressives, 8 epileptics, 48 cases of Alzheimer and vascular dementia, 23 cases of alcoholic dementia, 14 cases of childhood psychosis, 47 encephalopaths, and 21 chronic alcoholics), all chronically hospitalized.
