Changes in Adiposity, Metabolic Measures From Atypicals to Aripiprazole

Completed · Phase 4

Conditions studied: Schizophrenia, Type 2 Diabetes Mellitus

In brief

This proposal aims to use well-validated methodologies such as dual energy x-ray absorptiometry (DEXA), frequently sampled oral glucose tolerance tests (fsOGTTs), and hyperinsulinemic euglycemic clamps to characterize the metabolic effects of 12 weeks of aripiprazole treatment following chronic pretreatment with olanzapine, quetiapine, risperidone or ziprasidone. We hypothesize that switching to aripiprazole treatment will induce improvements in total body adiposity, inflammation (e.g., high sensitivity C-reactive protein \[hsCRP\]), glucose metabolism (e.g., insulin sensitivity) and lipid metabolism (e.g., fasting plasma triglyceride), in comparison to chronic pretreatment with olanzapine, risperidone and quetiapine.
