[Schizophrenia and HLA antigens].

38 schizophrenic patients (21 hebephrenics and 17 paranoids) and 124 healthy subjects were matched for HLA antigens. HLA typing was determined by the microdroplet lymphocyte toxicity method developed by Terasaki of UCLA. In order to detect 47 HLA antigens as many as 118 antisera were used. No significant differences in HLA typing were found between the two groups. However, the separate evaluation of HLA antigens of hebephrenic schizophrenics did not give any statistical significance, as well. The authors discuss these findings in the light of previous studies on the topic.
