Characterization of Beta Cell Failure
|Study Design:||Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Basic Science
- Insulin secretion [ Time Frame: 1 day ]
|Study Start Date:||May 2009|
|Estimated Study Completion Date:||December 2011|
|Estimated Primary Completion Date:||December 2010 (Final data collection date for primary outcome measure)|
We have identified a subgroup of individuals with a good compliance to lifestyle intervention to prevent diabetes who lose body weight and increase insulin sensitivity, however they remain impaired glucose tolerant. These individuals show a deterioration in insulin secretory function.
We will identify a highly selected group of subjects with prediabetes that displays a large defect in insulin secretory function.We will study 50 individuals who display these characteristics and 50 subjects who do not display these characteristics. Their insulin secretion capacity in response to different secretagogues (glucose, GLP-1, arginine) will be studied. We expect to detect new pathophysiologic aspects that lead to beta cell failure particularly in this group.
