Official Title  ICMJE Effect of 6 Weeks Resveratrol Supplementation on Vascular Function in CKD
Brief Summary The proposed research is clinical study evaluating the therapeutic benefits of resveratrol on vascular function in patients with chronic kidney disease (CKD). The study aims to establish that resveratrol will improve endothelial function and functional performance by reducing oxidative stress and in conjunction with lowering markers of inflammation and oxidative stress.
Detailed Description

Patients with chronic kidney disease (CKD) have an exceptionally high risk for cardiovascular disease (CVD), and are 10 times more likely to die from CVD prior to requiring dialysis or kidney transplantation. Inflammation, oxidative stress and vascular dysfunction (impaired endothelial function and increased large elastic artery stiffness), are highly prevalent in CKD and contribute to the high incidence of CVD in this patient population. In addition, patients with CKD suffer from high rates of cognitive decline for which we lack effective therapies. Thus, therapeutic interventions targeting inflammation, oxidative stress, vascular dysfunction in CKD are a priority.

Wine intake, which is known to be rich in various polyphenolic compounds, might have a variety of health benefits. Among these polyphenols, the stilbene derivative resveratrol (RSV), a naturally occurring polyphenol found in grapes and red wine, has recently come to light, as it has been shown to exert potent anti-diabetic, anti-oxidative and anti-inflammatory actions. Importantly, recent studies have demonstrated that resveratrol is well-tolerated (37) and may confer similar benefits in individuals at high risk of CVD, such as improved endothelial function in individuals with metabolic syndrome (i.e. diabetes)

The primary goal of this application is to determine whether 6 wks resveratrol (RSV) supplementation improves vascular function by reducing oxidative stress in a randomized, double-blind, cross-over study of 25 patients with diabetic kidney disease. The investigators hypothesize that: 1) 6 wks RSV will improve vascular function as measured via BA-FMD vs. placebo and 2) that the improvement in vascular function will be related, at least partially, to a reduction in oxidative stress.
