Filter by:This study evaluates the effect of different doses of metformin on the function of endothelium in people with pre-diabetes. One group of the patients will receive metformin in dose: 1500 mg, the second one will receive 3000 mg/day. The parameters from healthy volunteers will be taken only at the study beginning to compare the test results with the parameters from patients with pre-diabetes. This group will be not treated with metformin (no intervention)
HYPOTHESIS: Impaired glucose tolerance (IGT) and impaired fasting glucose (IFG) have distinct pathophysiologic etiologies. Therefore, therapeutic interventions designed to correct the specific underlying pathogenic abnormalities in IGT and IFG will be required to optimally prevent the progressive beta cell failure and development of overt type 2 diabetes.
The purpose of open-label study is to evaluate the efficacy and safety of AO-128 (Voglibose) 0.6 mg/day in patients with impaired glucose tolerance (IGT) who had been non-responsive to diet therapy and exercise therapy, and follow up the progress after the end of treatment in patients who was assessed as normoglycemic.
This research study will examine brain glucose metabolism after an overnight fast to determine the effect of exenatide on brain glucose metabolism and lipid metabolism.
Hypothesis: There is a high rate of glucose intolerance among Hong Kong Chinese. The investigators plan to screen Hong Kong Chinese from the community with oral glucose tolerance test (OGTT). The subjects will be referred from GP centers in the community and self-referred with public advertisement on this survey.
