Overall , this meta- analysis shows that in diabetic patients , taking vitamin D had significant effects on hs-CRP and MDA levels , and significantly increased NO , TAC and GSH levels
In this systematic review and meta- analysis of r and omized controlled trials ( RCTs ) , the effects of vitamin D supplementation on biomarkers of inflammation and oxidative stress in diabetic patients are summarized .
The effect of calcitriol on lipid profile and oxidative stress in hyperlipidemic patients with type 2 diabetes mellitus
BACKGROUND Cardiovascular mortality is high among diabetic patients due to abnormalities in the plasma lipid and lipoprotein metabolism , and increased oxidative stress . This study aim ed to investigate the effects of active vitamin D on serum lipids and oxidative stress markers in type 2 diabetic patients . METHODS A double-blind r and omized placebo-controlled trial was carried out in 70 participants with type 2 diabetes , aged 30 - 75 years of age . The participants were r and omly assigned to two groups . One group received two capsules of calcitriol ( 0.25 µg 1,25-dihydroxycholecalciferol per capsule ) per day . The second group received placebo tablets . All participants received their oral hypoglycemic drugs as prescribed by the endocrinologist . At the beginning , after 6 weeks , and at the end of the 12-week supplementation trial , serum total cholesterol , low-density lipoprotein ( LDL ) , high-density lipoprotein ( HDL ) , triglyceride ( TG ) , and serum malondialdehyde ( MDA ) levels were measured . RESULTS There was a significant reduction in total cholesterol , LDL-cholesterol , TG , and MDA levels in both treatment and placebo groups ( P < 0.05 ) . Serum HDL-cholesterol level decreased significantly in the placebo group ( P < 0.05 ) , while it remained unchanged in the treatment group . However , the P values related to the between group ’s comparisons were not significant for any variables . CONCLUSION Active vitamin D  reduced lipid profile and oxidative stress markers in diabetic patients compared to the control group , but these alterations were not statistically
Overall , this meta- analysis shows that in diabetic patients , taking vitamin D had significant effects on hs-CRP and MDA levels , and significantly increased NO , TAC and GSH levels
