| Outline of Final Research Achievements |
We investigated the mechanism of glucose metabolism and weight gain due to atypical antipsychotics. The prevalence of abnormal glucose tolerance in schizophrenia was examined. Among patients with normal fasting glucose, 17.3% had impaired glucose tolerance, and 1.3% were diagnosed with diabetes. Association between glucose-dependent insulinotropic polypeptide (GIP) receptor polymorphism and body mass index in olanzapine-treated schizophrenia was examined. GIPR polymorphism may predict weight gain in schizophrenia. The GIP concentration was measured at two types of antipsychotics. AUC-GIP was higher in oral administration of aripiprazole and quetiapine than in naive. Antipsychotics might affect on increased incretin secretion.
