摘要

The second generation antipsychotic drugs (SGAs) are effective in treating patients with schizophrenia and have been considered as the first line therapy. Recently, increasing attention has been drawn to the potential diabetogenic effect of these novel antipsychotics. The goal of this study was to evaluate the time-dependent effects of olanzapine treatment on pancreatic beta cell function in SGA-naïve schizophrenic patients. Forty-two schizophrenic subjects received olanzapine therapy for 8. weeks and thirty-three of them completed the trial. Of whom 33 completers (21 male, mean ± SD age: 37.6 ± 8.0. years) were inpatients and unexposed to SGA. The metabolic parameters were quantitatively assessed at weeks 0, 2, 4, and 8 by the intravenous glucose tolerance test. After 56-day olanzapine treatment, subjects had significant increases in body weight and as well as in the levels of triglyceride, total cholesterol, and low-density lipoprotein. Insulin secretion significantly decreased at week 2, returned to baseline at week 4, and significantly increased at week 8. Of the total samples, 18.2% and 33.3% of them met the criteria for significant weight gain and metabolic syndrome after 8-week olanzapine treatment, respectively. This study indicates that olanzapine-treated schizophrenic patients displayed biphasic changes in insulin secretion to a hyperglycemic challenge. The results of this study support that olanzapine might directly influence pancreatic beta cell function.
