The drug also reduced homeostasis model assessment of insulin resistance ( HOMA-IR ) index , systolic blood pressure , and diastolic blood pressure among participants with T2DM .
The changes in hemoglobin A1c ( HbA1c ) , low-density lipoprotein cholesterol , and high-density lipoprotein cholesterol were negligible .
Subgroup analysis comparing the resveratrol supplementation doses of < 100 mg/d versus ≥ 100 mg/d revealed a significant difference in fasting plasma glucose .
In particular , the latter dose presented more favorable results .
This meta- analysis provides evidence that supplementation of resveratrol may benefit management of T2DM
Although the regular consumption of resveratrol has been known to improve glucose homeostasis and reverse insulin resistance in type 2 diabetes mellitus ( T2DM ) , the reported results are inconsistent .
Thus , we aim ed to assess the effects of resveratrol on glycemic control and insulin sensitivity among patients with T2DM .
One-year supplementation with a grape extract containing resveratrol modulates inflammatory-related microRNAs and cytokines expression in peripheral blood mononuclear cells of type 2 diabetes and hypertensive patients with coronary artery disease.
Numerous studies have shown that resveratrol ( RES ) exerts anti-inflammatory effects but human trials evidencing these effects in vivo are limited . Furthermore , the molecular mechanisms triggered in humans following the oral intake of RES are not yet understood . Therefore , the purpose of this study was to investigate the molecular changes in peripheral blood mononuclear cells ( P BMC s ) associated to the one-year daily intake of a RES enriched ( 8 mg ) grape extract ( GE-RES ) in hypertensive male patients with type 2 diabetes mellitus ( T2DM ) . We used microarrays and RT-PCR to analyze expression changes in genes and microRNAs ( miRs ) involved in the inflammatory response modulated by the consumption of GE-RES in comparison to a placebo and GE lacking RES . We also examined the changes in several serobiochemical variables , inflammatory and fibrinolytic markers . Our results showed that supplementation with GE or GE-RES did not affect body weight , blood pressure , glucose , HbA1c or lipids , beyond the values regulated by gold st and ard medication in these patients . We did not find either any significant change on serum inflammatory markers except for a significant reduction of ALP and IL-6 levels . The expression of the pro-inflammatory cytokines CCL3 , IL-1β and TNF-α was significantly reduced and that of the transcriptional repressor LRRFIP-1 increased in P BMC s from patients taking the GE-RES extract . Also , a group of miRs involved in the regulation of the inflammatory response : miR-21 , miR-181b , miR-663 , miR-30c2 , miR-155 and miR-34a were found to be highly correlated and altered in the group consuming the GE-RES for 12 months . Our results provide preliminary evidence that long-term supplementation with a grape extract containing RES downregulates the expression of key pro-inflammatory cytokines with the involvement of inflammation-related miRs in circulating immune cells of T2DM hypertensive medicated patients and support a beneficial immunomodulatory effect in these patients
