Effect of vitamin C combined with vitamin E on antioxidant capacity and inflammatory response in patients with hemodialysis

Objective: To study the effect of vitamin C combined with vitamin E on antioxidant capacity and inflammatory response in patients with hemodialysis. Methods: A total of 116 patients with uremia who received hemodialysis in the hospital between December 2014 and January 2017 were collected and divided into control group and observation group by random number table, each with 58 cases. Control group received vitamin C intervention, and observation group received vitamin C combined with vitamin E intervention. The differences in serum levels of antioxidant indexes, pro-inflammatory mediators and anti-inflammatory mediators were compared between the two groups before intervention and 6 weeks after intervention. Results: Before intervention, serum levels of antioxidant indexes, pro-inflammatory mediators and anti-inflammatory mediators were not significantly different between the two groups. After intervention, serum SOD, GSH-PX and T-AOC levels of both groups of patients were higher than those before treatment while IL-1, IL-2, IL-6, IL-8, IL-4, IL-10 and IL-13 levels were lower than those before treatment, and serum SOD, GSH-PX and T-AOC levels of observation group were higher than those of control group while IL-1, IL-2, IL-6, IL-8, IL-4, IL-10 and IL-13 levels were lower than those of control group. Conclusion: Vitamin C combined with vitamin E intervention can effectively enhance the antioxidant capacity and suppress the systemic inflammatory state in patients with hemodialysis.
