title: Interferon, cortisone, and antivirals in the treatment of chronic viral hepatitis: a review of 30 years of therapy.
abstract: Over the last 30 years many approaches have been adopted to treat chronic hepatitis. We conducted a meta-analysis to assess the efficacy of various types of treatments. We selected 4 studies of cortisone in chronic hepatitis B; 21 trials of interferon treatment, 6 in chronic hepatitis B, 10 in chronic hepatitis C, and 5 in chronic hepatitis D; and 5 of combined cortisone and interferon treatment in chronic hepatitis B. The Mantel-Haenszel-Peto method was applied to extrapolated data. We completed the study by analyzing four studies of cortisone treatment of chronic hepatitis C, two of cortisone plus interferon alpha (IFN-alpha) for chronic hepatitis C, and antiviral therapy for hepatitis B, C, and D. Trials administering cortisone for chronic hepatitis B had an overall OR of 0.29 (CI 0.12-0.73). No virologic remissions were observed in patients with hepatitis C receiving prednisone, even if those with features of autoimmunity achieved a biohumoral sustained response. Overall ORs in the trials were were as follows: IFN for chronic hepatitis B, 0.27 (CI 0.17-0.46); IFN for chronic hepatitis C, 0.3 (CI 0.21-0.44); IFN for chronic hepatitis D, 0.16 (CI 0.06-0.47); and cortisone plus interferon for chronic hepatitis B, 0.25 (CI 0.15-0.41). Sustained response rates of chronic hepatitis C ranged from 15-24.2%. The only encouraging results were obtained by antivirals. To date the lack of a specific antiviral drug makes it uncertain as to the preferred agent for this disease.
