BACKGROUND: Ribavirin is associated with haemolytic anaemia. Antioxidants have been reported to decrease severity of this anaemia.
AIM: To determine effect of vitamin E supplementation on ribavirin-associated haemolysis in chronic hepatitis C treated with standard alpha-interferon and ribavirin.
METHODS: Fifty-one naive chronic hepatitis C patients were randomized to receive either alpha-interferon/ribavirin therapy (control) or therapy plus vitamin E 800 IU b.d. with 24-week follow-up. Alanine aminotransferase ALT, haemoglobin and reticulocyte percentage were monitored. Symptoms and health-related quality of life were also monitored at each visit.
RESULTS: Forty-seven subjects were treated (27 vitamin E /20 controls). Thirteen withdrew because of adverse effects or non-compliance. Groups were similar in demographics, genotype and baseline lab indices. Comparison with baseline, treatment and follow-up values showed a significant haemoglobin and ALT reduction in both groups. There was no significant difference in haemoglobin and reticulocyte percentage between groups. Sustained viral response was not significantly different between vitamin E (11/18) and control (6/16) groups. Three patients required ribavirin dose-reduction in the vitamin E group compared with two controls. Health-related quality of life during and end-of-treatment was not different between groups.
CONCLUSIONS: Vitamin E supplementation alone during standard alpha-interferon and ribavirin therapy does not appear to diminish ribavirin-associated haemolysis.
