Vascular Function, Endothelin, and Inflammation in Pre-diabetic Obesity Versus Lean Healthy Controls
| Status: | Completed |
|---|---|
| Conditions: | Obesity Weight Loss, Endocrine, Diabetes |
| Therapuetic Areas: | Endocrinology |
| Healthy: | No |
| Age Range: | 18 - 55 |

We intend to pursue the following Aims:
1. Does inflammation contribute importantly to concurrent defects in vascular and metabolic
dysfunction in human pre-diabetic obesity?
2. Are there benefits of anti-inflammatory treatment strategies in pre-diabetic obesity in
the context of existing treatment with metformin?
3. Are there benefits of anti-inflammatory treatment strategies in pre-diabetic obesity in
the context of existing treatment with lisinopril?
The intent of the current project is to efficiently and at low cost generate preliminary data
along each of these lines of questioning, studying the minimum number of subjects required to
assess the viability of the question using the current measurement approaches.
