Clinical Trial of the Effects of Coenzyme Q10 Supplementation on Biomarkers of Inflammation and Oxidative Stress in Diabetic Hemodialysis Patients

Abstract

Background: The aim of the study was to determine the effects of coenzyme Q10 (CoQ10) supplementation on biomarkers of intlainination and oxidative stress among diabetic hemodialysis (HD) patients. Methods: Sixty diabetic FIT) patients participated in the randomized, double blind, placebo-controlled clinical trial. They were randomly assigned into two groups to intake either 60 mg CoQ10 supplements (n = 30) or placebo (n = 30) twice a day for 12 weeks. Results: After 12 weeks of intervention, CoQ10 supplementation significantly increased total antioxidant (TAC) (54.921 +/- 26.437 vs. -126.781 +/- 26.437, P < 0.001) and nitric oxide (NO) levels (4.121 +/- 1.314 vs. -1.427 +/- 1.314, P = 0.006) and decreased C-reactive protein (CRP) (-1.302 +/- 0.583 vs. 0.345 +/- 0.583, 0.042) levels compared with the placebo. We did not observe any significant effect of CoQ10 supplementation on malondialdehyde (MDA) and glutathione (GSH) levels compared with the placebo. Conclusions: Overall, our study showed that CoQ10 supplementation to diabetic HD patients for 12 weeks was associated with increased levels of TAC and NO levels and decreased level of high-sensitivity CRP (hs-CRI') levels, but did not have any beneficial effects on MDA and GSH.
