Abstract

In an attempt to define the autoimmune status of members of multicase families with schizophrenia, sera of both patients and healthy relatives from 28 such cases were tested for antinuclear antibodies, anti-double-strandedDNA, and anti-single-strandedDNA autoantibodies. These autoantibodies were significantly more frequent in both schizophrenic patients and healthy relatives than in normal subjects. Immunoglobulin (Ig) M anti-DNA antibodies were more common in patients, whereas in healthy relatives, IgG anti-DNA antibodies were more common. No significant differences were found between schizophrenic patients and their healthy relatives. The data indicate that an autoimmune process may be involved in the etiology of a subset of patients with schizophrenia.
