Background
Intake of dietary antioxidants is inversely associated with reduced markers of atherosclerosis development such as carotid intima-media thickness (CIMT).
Objective
This study was designed to assess the effects of selenium supplementation on CIMT and metabolic profiles of in diabetic hemodialysis (HD) patients.
Materials and Methods
This randomized, double-blind, placebo-controlled trial was performed on 60 diabetic HD patients. Subjects were randomly assigned to receive selenium supplements or placebo (starch). Individuals in the selenium group (n=30) received 200 μg selenium per day in the placebo group (n=30) received for 24 weeks. Fasting blood samples were taken at the study baseline and after 24 weeks of intervention.
Results
Following the administration of selenium supplements, was observed a significant reduction in serum insulin levels (P=0.003), insulin resistance (P=0.003), total cholesterol (P=0.008), LDL-cholesterol (P<0.001) and C-reactive protein (CRP) (P<0.001), and a significant increase in insulin sensitivity (P<0.001), HDL-cholesterol (P<0.001) and toal glutathione (GSH) (P<0.001) compared with the placebo.
Conclusions
Selenium supplementation in diabetic HD patients had beneficial effects on markers of insulin metabolism, total-, LDL-, HDL-cholesterol, CRP and GSH levels.
