Viral antibodies and interferon in acute psychiatric disorders

Abstract

In a prospective study of 54 patients with acute psychiatric disorders, interferon and antibodies in serum and CSF were measured to 19 microbes by the complement fixation (CF) test and to 7 viruses by enzyme immunoassay (EIA). The CF test revealed a fourfold or greater change (p less than .001) in serum antibody titers in 20 patients, and EIA showed a twofold or greater change in CSF titers in 7 patients. Pathological serum/CSF antibody ratio by EIA was observed in 8 patients. The results suggest that viral infections and inflammatory processes have significance in the etiopathogenesis of acute psychiatric disorders.
