Implication

Meta-analysis demonstrates increased sustained response with longer interferon treatment in hepatitis C, indicating 12-month regimens optimize viral clearance and enzyme normalization.

Key Points

To evaluate the efficacy of higher doses and extended treatment durations of interferon compared with standard regimens in chronic hepatitis C, and to assess interferon efficacy in acute hepatitis C.
Meta-analysis conducted using Peto and DerSimonian-Laird methods with heterogeneity and sensitivity analyses.
Included 17 randomized trials versus control and 16 trials comparing different interferon regimens in chronic hepatitis C, along with 4 trials in acute hepatitis C.
In chronic hepatitis C, extending treatment from 6 to 12 months increased sustained ALT response rates by 16% at 3 MU (95% CI: 9%–23%; P < .001) and by 20% at 6 MU (95% CI: 7%–33%; P = .003).
Increasing dose from 3 MU to 6 MU increased 12-month sustained response by 17% (95% CI: 7%–28%; P < .001), while standard 6-month therapy improved sustained response by 21% (95% CI: 13%–28%; P < .001) over controls.
In acute hepatitis C, 3-month interferon treatment was superior to control for complete ALT response (69% vs 29%; P < .001), 12-month sustained response (53% vs 32%; P = .02), and HCV-RNA clearance (41% vs 4%; P < .001).
