    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 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 Resveratrol has been reported to have potent anti-atherosclerotic effects in animal studies . However , there are few interventional studies in human patients with atherosclerogenic diseases . The cardio-ankle vascular index ( CAVI ) reflects arterial stiffness and is a clinical surrogate marker of atherosclerosis . The aim of the present study was to investigate the effect of resveratrol on arterial stiffness assessed by CAVI in patients with type 2 diabetes mellitus (T2DM).In this double-blind , r and omized , placebo-controlled study , 50 patients with T2DM received supplement of a 100 mg resveratrol tablet ( total resveratrol : oligo-stilbene 27.97 mg/100 mg/day ) or placebo daily for 12 weeks . CAVI was assessed at baseline and the end of study . Body weight ( BW ) , blood pressure ( BP ) , glucose and lipid metabolic parameters , and diacron-reactive oxygen metabolites ( d-ROMs ; an oxidative stress marker ) were also measured . Resveratrol supplementation decreased systolic BP ( -5.5 ± 13.0 mmHg ) , d-ROMs ( -25.6 ± 41.8 U.CARR ) , and CAVI ( -0.4 ± 0.7 ) significantly ( P < 0.05 ) and decreased BW ( -0.8 ± 2.1 kg , P = 0.083 ) and body mass index ( -0.5 ± 0.8 kg/m2 , P = 0.092 ) slightly compared to baseline , while there were no significant changes in the placebo group . Decreases in CAVI and d-ROMs were significantly greater in the resveratrol group than in the placebo group . Multivariate logistic regression analysis identified resveratrol supplementation as an independent predictor for a CAVI decrease of more than 0.5.In conclusion , 12-week resveratrol supplementation may improve arterial stiffness and reduce oxidative stress in patients with T2DM . Resveratrol may be beneficial in preventing the development of atherosclerosis induced by diabetes . However , a large-scale cohort study is required to vali date the present findings Purpose The grape and wine polyphenol resveratrol exerts cardiovascular benefits but evidence from r and omized human clinical trials is very limited . We investigated dose-depending effects of a resveratrol-containing grape supplement on stable patients with coronary artery disease ( CAD ) treated according to currently accepted guidelines for secondary prevention of cardiovascular disease . Methods In a triple-blind , r and omized , placebo-controlled , one-year follow-up , 3-arm pilot clinical trial , 75 stable-CAD patients received 350 mg/day of placebo , resveratrol-containing grape extract ( grape phenolics plus 8 mg resveratrol ) or conventional grape extract lacking resveratrol during 6 months , and a double dose for the following 6 months . Changes in circulating inflammatory and fibrinolytic biomarkers were analyzed . Moreover , the transcriptional profiling of inflammatory genes in peripheral blood mononuclear cells ( P BMC s ) was explored using microarrays and functional gene expression analysis . Results After 1 year , in contrast to the placebo and conventional grape extract groups , the resveratrol-containing grape extract group showed an increase of the anti-inflammatory serum adiponectin ( 9.6 % , p = 0.01 ) and a decrease of the thrombogenic plasminogen activator inhibitor type 1 ( PAI-1 ) ( −18.6 % , p = 0.05 ) . In addition , 6 key inflammation-related transcription factors were predicted to be significantly activated or inhibited , with 27 extracellular-space acting genes involved in inflammation , cell migration and T-cell interaction signals presenting downregulation ( p < 0.05 ) in P BMC s. No adverse effects were detected in relation to the study products . Conclusions Chronic daily consumption of a resveratrol-containing grape nutraceutical could exert cardiovascular benefits in stable-CAD patients treated according to current evidence -based st and ards , by increasing serum adiponectin , preventing PAI-1 increase and inhibiting atherothrombotic signals in P BMC The objective of this study was to examine the effectiveness of resveratrol in lowering blood glucose in the presence of st and ard antidiabetic treatment in patients with type 2 diabetes , in a r and omized placebo-controlled double-blinded parallel clinical trial . A total of 66 subjects with type 2 diabetes were enrolled in this study and r and omly assigned to intervention group which was supplemented with resveratrol at a dose 1 g/day for 45 days and control group which received placebo tablets .  Body weight , blood pressure , fasting blood glucose , haemoglobin A1c , insulin , homeostatic assessment s for insulin resistance , triglycerides , total cholesterol , low density lipoprotein , high density lipoprotein , and markers of liver and kidney damage were measured at baseline and after 45 days of resveratrol or placebo supplementation . Resveratrol treatment significantly decreased systolic blood pressure , fasting blood glucose , haemoglobin A1c , insulin , and insulin resistance , while HDL was significantly increased , when compared to their baseline levels . On the other h and , the placebo group had slightly increased fasting glucose and LDL when compared to their baseline levels . Liver and kidney function markers were unchanged in the intervention group . Overall , this study showed that resveratrol supplementation exerted strong antidiabetic effects in patients with type 2 diabetes CONTEXT Metabolic syndrome ( MetS ) is associated with low- grade inflammation , which may harmfully affect bone . Resveratrol ( RSV ) possesses anti-inflammatory properties , and rodent studies suggest bone protective effects . OBJECTIVE This study sought to evaluate effects of RSV treatment on bone in men with MetS. SETTING AND DESIGN The study was conducted at Aarhus University Hospital as a r and omized , double-blinded , placebo-controlled trial assessing changes in bone turnover markers , bone mineral density ( BMD ) , and geometry . PARTICIPANTS The study population comprised 74 middle-aged obese men with MetS recruited from the general community , of which 66 completed all visits . Mean age of participants was 49.3 ± 6.3 years and mean body mass index was 33.7 ± 3.6 kg/m(2 ) . INTERVENTION Oral treatment with 1.000 mg RSV ( RSV(high ) ) , 150 mg RSV ( RSV(low ) ) , or placebo daily for 16 weeks . MAIN OUTCOME MEASURE Prespecified primary endpoint was change in bone alkaline phosphatase ( BAP ) . RESULTS BAP increased dose dependently with RSV ( R = 0.471 , P < .001 ) , result ing in a significantly greater increase in BAP in the RSV(high ) group compared with placebo at all time-points ( week 4 , 16.4 ± 4.2 % , P < .001 ; week 8 , 16.5 ± 4.1 % , P < .001 ; week 16 , 15.2 ± 3.7 % , P < .001 ) . Lumbar spine trabecular volumetric bone mineral density ( LS vBMD(trab ) ) also increased dose dependently with RSV ( R = 0.268 , P = .036 ) , with a significant increase of 2.6 ± 1.3 % in the RSV(high ) group compared with placebo ( P = .043 ) . In addition , changes in BAP and LS vBMD(trab ) were positively correlated ( R = 0.281 , P = .027 ) . No consistent changes were detected in bone density at the hip . CONCLUSIONS Our data suggest that high-dose RSV supplementation positively affects bone , primarily by stimulating formation or mineralization . Future studies of longer duration comprising population s at risk of osteoporosis are needed to confirm these results OBJECTIVE To determine whether resveratrol supplementation can improve insulin sensitivity and promote overall metabolic health on top of st and ard diabetes care . RESEARCH DESIGN AND METHODS Seventeen subjects with well-controlled type 2 diabetes ( T2D ) were treated with placebo and 150 mg/day resveratrol ( resVida ) in a r and omized double-blind crossover study for 30 days . The main outcome measure was insulin sensitivity by the hyperinsulinemic-euglycemic clamp technique . RESULTS Hepatic and peripheral insulin sensitivity were not affected by resveratrol treatment . Intrahepatic lipid content also remained unaffected by resveratrol ; however , the change in intrahepatic lipid content correlated negatively with plasma resveratrol levels ( R = −0.68 , P = 0.03 ) . Intramyocellular lipid content increased in type 2 muscle fibers ( P = 0.03 ) , and systolic blood pressure tended to decrease ( P = 0.09 ) upon resveratrol treatment . In addition , resveratrol significantly improved ex vivo mitochondrial function ( state 3 and state U respiration upon malate with octanoyl-carnitine , P < 0.005 ) . Intriguingly , a correlation was found between plasma levels of a metabolite of resveratrol  ( dihydror
