Abstract

Objective To assess the effect of antioxidant supplementation on hepatitis C viral load, transaminases and oxidative status. Methods We performed a randomized, placebo-controlled, double-blind trial to assess the effect of antioxidant supplementation on serum alanine aminotransferase, plasma hepatitis C viral load as well as oxidative and antioxidant markers in patients with hepatitis C virus infection. The participants received a daily dose of ascorbic acid (500 mg), D-alpha-tocopherol (9451 U) and selenium (200 mu g) or placebo tablets for 6 months. Results Twenty-three patients were included. During supplementation, the antioxidant group had significantly higher levels of plasma ascorbic acid and a-tocopherol than the placebo group and the activity of erythrocyte glutathione peroxidase had significantly increased from baseline to month 6. No differences were observed in serum alanine aminotransferase and logo-transformed plasma hepatitis C virus-RNA between the groups or changes from the baseline at any time. No consistent differences between groups or changes from the baseline with respect to erythrocyte activities of antioxidative enzymes (glutathione reductase, superoxide dismutase and catalase) or plasma levels of oxidative markers (malondialdehyde and 2-amino-adipic semialdehyde) were found. Conclusion Supplementation with vitamin C, E and selenium increased the antioxidant status, but had no effects on alanine aminotransferase, viral load or oxidative markers.
