BACKGROUND: Increasing evidence indicates that iron cytotoxicity plays an important role in the pathogenesis of chronic hepatitis C (CHC). However, the biochemical effects of iron reduction therapy on CHC remain to be confirmed in a controlled study. This study aimed to test whether iron removal by repeated phlebotomy improves serum alanine aminotransferase (ALT) levels in patients with CHC. METHODS: Patients were randomly assigned to an iron reduction therapy or control group. The patients in the treatment group received 3-month iron reduction therapy by biweekly phlebotomy, while the patients in the control group were followed up for 3 months with regular blood tests alone. RESULTS: Thirty-three patients completed the 3-month treatment, while 29 patients received the complete follow-up. The serum ALT levels were reduced from 118 +/- 79 to 73 +/- 39 IU/L in the treatment group, but did not change in the control group (106 +/- 45 versus 107 +/- 48 IU/L). Posttreatment enzyme activity was decreased significantly from the baseline. Furthermore, it was significantly lower than the 3-month control level. Although 5 patients withdrew from the study, none was affected by any side effects of repeated phlebotomy that required them to discontinue the treatment. CONCLUSIONS: This short-term controlled trial demonstrated the biochemical efficacy and safety of iron reduction therapy for patients with CHC.
