Objective  To evaluate the effectiveness and safety of different doses of interferon alfa (INF-α) in the treatment of chronic hepatitis C (CHC).
Methods  Such databases as MEDLINE, EMbase, CENTRAL, CBM, CNKI, VIP and WanFang Data were searched to collect the randomized controlled trials (RCTs) on different doses of INF-α in the treatment of CHC published before August, 2012. According to the inclusion and exclusion criteria, two reviewers independently screened literature, extracted data and evaluated the quality of the included studies, and then meta-analysis was performed using RevMan 5.0 software.
Results  A total of 13 RCTs involving 1 442 patients were included. The results of meta-analysis on different doses of INF-α showed that, a) There was no significant difference in the complete response rate between the 3 MU dose group and the 1 MU dose group (RR=0.83, 95%CI 0.52 to 1.32, P=0.43), but there was significant difference in the sustained response rate between those 2 groups (RR=1.89, 95%CI 1.00 to 3.59, P=0.05); and b) No significant differences were found in the complete response rate among the 3 MU dose group, the 6 MU dose group, and the 1 MU dose group.
Conclusion  INF-α in dose of 3 MU, 3 times daily, is effective in treating CHC, but it would not rule out that higher dose takes more effective action. When INF-α is used to treat CHC, an individualized medication should be applied according to patients’ tolerance and economic status.
