Metformin and Vascular Function in Prediabetes

Internal Medicine Endocrinology Heart and Vascular Diabetes Vascular Disease Heart Disease Adult Subjects Female Subjects Male Subjects

The goal of this clinical trial is to investigate whether metformin improves vascular function in individuals with prediabetes. The main questions it aims to answer are:

1. Does metformin improve large conduit artery endothelial function in individuals with prediabetes?
2. Does metformin improve microvascular endothelial function in individuals with prediabetes?

Researchers will compare metformin to a placebo to see if metformin improves vascular function in prediabetes.

The trial duration is 12 weeks. Participants will take metformin or a placebo once a day for 2 weeks. After 2 weeks, participants will take metformin or a placebo twice a day for the remaining 10 weeks. There will be a screening visit, two baseline visits, a 4-week safety visit, and two 12-week end-of-study visits. Adherence will be calculated from pill count and adverse events will be quantified via a questionnaire.

Curcumin and vascular function in CKD

Internal Medicine Nephrology Heart and Vascular Kidney Disease Vascular Disease Heart Disease Adult Subjects Female Subjects Male Subjects

The proposed research is clinical study evaluating the therapeutic benefits of curcumin on vascular function in patients with chronic kidney disease (CKD). The study aims to establish that curcumin will improve endothelial function and reduce large artery stiffness by reducing oxidative stress and in conjunction with lowering markers of inflammation and oxidative stress. In addition, the study will evaluate the potential benefit of curcumin on cognitive function in patients with CKD.
