title: Hemodialysis in the treatment of chronic schizophrenic patients: a double-blind crossover study.
abstract: In order to examine the reported beneficial effects of hemodialysis in chronic schizophrenic patients, a double-blind crossover study was carried out. Of the 47 patients considered for treatment, 10 diagnosed as chronic schizophrenics according to the Feighner and DSM-III criteria were accepted to the study. Seven of these patients completed the full program, four of whom belonged to a large family with a high incidence of schizophrenia. All patients were on antipsychotic medication throughout the study. Psychopathological evaluations were performed regularly in a blind fashion using the Comprehensive Psychopathological Rating Scale (CPRS) and the Nurse Observation Scale for Inpatient Evaluation (NOSIE-30). Samples of blood, urine, cerebrospinal fluid, and dialysate were obtained for examination. Three patients improved during active dialysis and two patients improved during sham treatment. Improvement in the five patients took place during the first treatment period. This study failed to demonstrate a therapeutic effect of hemodialysis superior to the sham procedures.
