    Input: ABSTRACT Objective “ The obesity epidemic ” has led to an increase in obesity-related conditions including non-alcoholic fatty liver disease ( NAFLD ) , for which effective treatments are in dem and . The polyphenol resveratrol prevents the development of experimental NAFLD through modulation of cellular pathways involved in calorie restriction . We aim ed to test the hypothesis that resveratrol alleviates NAFLD in a r and omised , clinical trial . Material s and methods A total of 28 overweight patients with transaminasemia and histological NAFLD were r and omised 1:1 to placebo or resveratrol 1.5 g daily for 6 months . Twenty-six participants completed the trial and underwent repeated clinical investigation , blood work , MR spectroscopy ; and 19 participants agreed to a repeat liver biopsy . Results Resveratrol treatment was generally not superior to placebo in improving plasma markers of liver injury ( primary outcome : alanine transaminase , p = 0.51 ) . Resveratrol-treated patients showed a 3.8 % decrease in liver lipid content ( p = 0.03 ) , with no difference between the two treatment arms ( p = 0.38 ) and no improvement of histological features .  Resveratrol treatment was not associated with improvements in insulin sensitivity or markers of the metabolic syndrome , except for a transient decrease in systolic BP . Microarray analysis and qRT-PCR revealed no major changes in expression profile . Also , we report a serious adverse event in a patient who developed fever and bicytopenia . Conclusions In this placebo-controlled , high-dose and long-term study , resveratrol treatment had no consistent therapeutic effect in alleviating clinical or histological NAFLD , though there may be a small ameliorating effect on liver function tests and liver fat accumulation Ageing is thought to be associated with decreased vascular function partly due to oxidative stress . Resveratrol is a polyphenol , which in animal studies has been shown to decrease atherosclerosis , and improve cardiovascular health and physical capacity , in part through its effects on Sirtuin 1 signalling and through an improved antioxidant capacity . We tested the hypothesis that resveratrol supplementation enhances training-induced improvements in cardiovascular health parameters in aged men . Twenty-seven healthy physically inactive aged men ( age : 65 ± 1 years ; body mass index : 25.4 ± 0.7 kg m(-2 ) ; mean arterial pressure ( MAP ) : 95.8 ± 2.2 mmHg ; maximal oxygen uptake : 2488 ± 72 ml O2 min(-1 ) ) were r and omized into 8 weeks of either daily intake of either 250 mg trans-resveratrol ( n = 14 ) or of placebo ( n = 13 ) concomitant with high-intensity exercise training . Exercise training led to a 45 % greater ( P < 0.05 ) increase in maximal oxygen uptake in the placebo group than in the resveratrol group and to a decrease in MAP in the placebo group only ( -4.8 ± 1.7 mmHg ; P < 0.05 ) . The interstitial level of vasodilator prostacyclin was lower in the resveratrol than in the placebo group after training ( 980 ± 90 vs. 1174 ± 121 pg ml(-1 ) ; P < 0.02 ) and muscle thromboxane synthase was higher in the resveratrol group after training ( P < 0.05 ) . Resveratrol administration also abolished the positive effects of exercise on low-density lipoprotein , total cholesterol/high-density lipoprotein ratio and triglyceride concentrations in blood ( P < 0.05 ) . Resveratrol did not alter the effect of exercise training on the atherosclerosis marker vascular cell adhesion molecule 1 ( VCAM-1 ) . Sirtuin 1 protein levels were not affected by resveratrol supplementation . These findings indicate that , whereas exercise training effectively improves several cardiovascular health parameters in aged men , concomitant resveratrol supplementation can blunt these effects Resveratrol is a naturally occurring polyphenolic compound . Numerous animal studies have been reported on its wide-ranging beneficial effects in the biological system including diabetes mellitus ( DM ) . We hypothesized , therefore , that oral supplementation of resveratrol would improve the glycemic control and the associated risk factors in patients with type 2 diabetes mellitus ( T2DM ) . The present clinical study was therefore carried out to test the hypothesis . Sixty-two patients with T2DM were enrolled from Government Headquarters Hospital , Ootacamund , India , in a prospect i ve , open-label , r and omized , controlled trial . Patients were r and omized into control and intervention groups . The control group received only oral hypoglycemic agents , whereas the intervention group received resveratrol ( 250 mg/d ) along with their oral hypoglycemic agents for a period of 3 months . Hemoglobin A(1c ) , lipid profile , urea nitrogen , creatinine , and protein were measured at the baseline and at the end of 3 months . The results reveal that supplementation of resveratrol for 3 months significantly improves the mean hemoglobin A(1c ) ( means ± SD , 9.99 ± 1.50 vs 9.65 ± 1.54 ; P < .05 ) , systolic blood pressure ( mean ± SD , 139.71 ± 16.10 vs 127.92 ± 15.37 ; P < .05 ) , total cholesterol ( mean ± SD , 4.70 ± 0.90 vs 4.33 ± 0.76 ; P < .05 ) , and total protein ( mean ± SD , 75.6 ± 4.6 vs 72.3 ± 6.2 ; P < .05 ) in T2DM . No significant changes in body weight and high-density lipoprotein and low-density lipoprotein cholesterols were observed . Oral supplementation of resveratrol is thus found to be effective in improving glycemic control and may possibly provide a potential adjuvant for the treatment and management of diabetes Background : Patients with schizophrenia ( SZ ) are generally overweight or obese and have several metabolic disorders . Additionally , such patients have a lower life expectancy and the main cause of their increased mortality is cardiovascular disease ( CVD ) . The objective of this study was to determine the efficacy of resveratrol supplementation on serum glucose and CVD risk factors in individuals with SZ . Methods and Results : This is a four-week r and omized , double-blind controlled trial ( registration No. : NCT 02062190 ) in which 19 men with a diagnosis of SZ , aged 18 to 65 , were assigned to either a resveratrol supplement group ( 200 mg/day ) or a placebo group ( 200 mg/day ) . In short , we did not observe significant changes after resveratrol supplementation . In the placebo group , we found a significant increase in total cholesterol levels ( p = 0.024 ) and in LDL-cholesterol ( p = 0.002 ) , as well as a decrease in body fat percentage ( p = 0.038 ) . The placebo group also showed an increase in triglycerides ( 9.19 % ) and a reduction in HDL-cholesterol ( 4.88 % ) . In the resveratrol group , triglycerides decreased ( 7.64 % ) . Conclusion : In summary , oral resveratrol in reasonably low dosages ( 200 mg daily ) brought no differences to body weight , waist circumference , glucose , and total cholesterol . It was possible to note that the lipid profile in the placebo group worsened and , although no significant differences were found , we can assume that resveratrol might prevent lipid profile damage and that the intervention affected the lipoprotein metabolism at various levels To assess the effect on exercise capacity and tolerability of resveratrol , 13 healthy , sedentary adult volunteers were enrolled in a r and omized crossover study comparing resveratrol and placebo over two 4-week periods , with a 2-week time between periods when subjects received no treatment . No significant changes in exercise duration or aerobic capacity ( peak oxygen uptake ) were observed . Gastrointestinal side effects were more common during resveratrol treatment ( 77 % vs. 15 % , p = 0.0048 ) . A small reduction in fasting glucose and small but statistically significant increases in liver enzymes , total cholesterol , and triglycerides were observed , although mean results remained within normal limits . There was no change in complete blood count , inflammatory markers , renal function , or other measures of liver function Background : Exercise can lead to acute oxidative stress , which can result in oxidative damage and induce inflammation . Resveratrol may reduce the levels of inflammatory cytokines . Thus , we investigated the effects of this compound on the plasma levels of tumor necrosis factor-α ( TNF-α ) and interleukin 6 ( IL-6 ) in male professional basketball players . Methods : Twenty healthy male professional basketball players were r and omized into two groups ( 10 each ) . For 6 weeks , they received daily either 200 mg of polygonum cuspidatum extract ( PCE ) st and ardized to contain 20 % trans-resveratrol equivalent to 40 mg trans-resveratrol or placebo . Indices of inflammation were measured before and after 6 weeks of supplementation . Results : There was a significant reduction in plasma levels of TNF-a and IL-6 after 6 weeks of supplementation ; while no change was observed in these markers in the control group . Conclusions : Present study shows that 6 weeks of PCE containing resveratrol supplementation reduces the inflammation in male professional basketball players The polyphenol resveratrol is considered to exert many beneficial actions , such as antioxidant , anti-inflammatory , insulin-sensitizer and anticancer effects . Its benefits in patients with type 2 diabetes mellitus ( T2DM ) are controversial . Our aims were to determine whether resveratrol supplementation at two different dosages ( 500 and 40mg/day ) for 6 months i ) reduced the concentrations of C-reactive-protein ( CRP ) and ii ) ameliorated the metabolic pattern of T2DM patients .  In the present double-blind , r and omized , placebo-controlled trial , 192 T2DM patients were r and omized to receive resveratrol 500mg/day ( Resv500arm ) , resveratrol 40mg/day ( Resv40arm ) or placebo for 6-months . At baseline and at the trial end , CRP values , anthropometric , metabolic and liver parameters were determined . No serious adverse event occurred . A dose-dependent , though not significant , CRP decrease of 5.6 % ( Resv40arm ) and 15.9 % ( Resv500arm ) was observed vs placebo . We failed to detect significant differences in weight , BMI , waist circumference , and values of arterial blood pressure , fasting glucose , glycated hemoglobin , insulin , C-peptide , free fatty acids , liver transaminases , uric acid , adiponectin , interleukin-6 , in both the Resv500 and Resv40 arms vs placebo . Total cholesterol and triglycerides slightly increased in the Resv500arm . Subgroup analyses revealed that lower diabetes duration ( in both Resv500 and Resv40arms ) , and , in the Resv500arm , younger age , aspirin use and being a smoker were associated with a significantly higher CRP reduction vs placebo . The supplementations with 40mg/day or 500mg/day resveratrol did neither reduce CRP concentrations , nor improve the metabolic pattern of T2DM patients CONTEXT Polycystic ovary syndrome ( PCOS ) is the most common endocrinopathy affecting women of reproductive age . Hyper and rogenism is the central feature of PCOS . Studies on isolated ovarian theca-interstitial cells suggest that resveratrol , a natural polyphenol , reduces and rogen production . OBJECTIVE This study was design ed to evaluate endocrine and metabolic effects of resveratrol on PCOS . DESIGN AND SETTING This was a r and omized ( 1:1 ) double-blind , placebo-controlled trial that evaluated the effects of resveratrol over a period of 3 months in an academic hospital . PATIENTS AND OTHER PARTICIPANTS Subjects with PCOS were identified according to the Rotterdam criteria . Thirty-four subjects were enrolled and 30 subjects completed the trial . Evaluations were performed at baseline and repeated after 3 months of treatment . INTERVENTION Resveratrol ( 1,500 mg p.o . ) or placebo were administered daily . MAIN OUTCOME MEASURE Primary outcome was the change in the serum total T. RESULTS Resveratrol treatment led to a significant decrease of total T by 23.1 % ( P = .01 ) . In parallel , resveratrol induced a 22.2 % decrease of dehydroepi and rosterone sulfate ( P = .01 ) , a decrease of fasting insulin level by 31.8 % ( P = .007 ) and an increase of the Insulin Sensitivity Index ( Matsuda and DeFronzo ) by 66.3 % ( P = .04 ) .
