Safety and efficacy of peginterferon plus ribavirin in patients with chronic hepatitis C and bridging fibrosis or cirrhosis.
The combination of pegylated interferon and ribavirin is the most effective therapy in patients with chronic hepatitis C. We evaluated this combination in unselected patients with bridging fibrosis or cirrhosis. Eighty patients were treated with peginterferon alpha-2b plus ribavirin. Hepatitis C virus serum RNA was monitored. Tolerance and safety were evaluated by the rate of treatment's discontinuation for any reason, and occurrence of serious clinical adverse events, respectively. Sustained virologic response (SVR) rate was 36.3% overall, and was observed in every group of patients except those who had previously failed to respond to the combination of interferon and ribavirin. No serious clinical adverse event occurred. Treatment was withdrawn in 18.7% of patients. Variables associated with discontinuation of treatment were low prothrombin index [OR: 1.16 (1.05;1.27)] and low body mass index [OR: 1.47 (1.12;1.92)]. Initial blood count abnormalities were not associated with cessation of treatment. Furthermore, early virologic response at week 8 and week 12 of treatment had similar predictive value for SVR. Combination therapy with peginterferon plus ribavirin seems effective in this group of patients, except in those who had previously failed to respond to the combination of interferon and ribavirin. This therapy is safe with appropriate monitoring, but tolerance seems worse in patients with the most advanced liver disease.
