Resveratrol is known to improve endothelial function in animals, but little is known about its effect on human subjects. Metabolic syndrome (MetS) is a cluster of cardiovascular risk factors underlying endothelial dysfunction. We hypothesized that the modified resveratrol, Longevinex, improves endothelial function in patients with MetS. Thirty-four patients who had been treated for MetS and lifestyle-related disease were randomly assigned to group A, in which Longevinex was administered for 3 months and then discontinued for 3 months, whereas in the time-matched group B, Longevinex was administered between 3 and 6 months. These 2 groups of patients received similar drugs at baseline for diabetes mellitus, dyslipidemia, or hypertension. Flow-mediated dilatation significantly increased during the administration of Longevinex but decreased to baseline 3 months after the discontinuation of Longevinex in the group A patients. Conversely, in the group B patients, flow-mediated dilatation remained unchanged for the first 3 months without Longevinex but was significantly increased 3 months after the treatment with Longevinex. Longevinex did not significantly affect blood pressure, insulin resistance, the lipid profile or inflammatory markers during 6-month follow-up. These results demonstrate that Longevinex specifically improves endothelial function in subjects with MetS who were receiving standard therapy for lifestyle-related disease. (C) 2011 Elsevier Inc.
