- Abstract
- Background/Aims
The combination therapy of peginterferon (PEG-IFN) and ribavirin is the standard treatment for hepatitis C virus (HCV) infection. However, few trials have involved patients with cirrhosis. The purpose of this study was to elucidate the efficacy and safety of treatment with PEG-IFN and ribavirin in patients with cirrhosis associated with HCV infection. Method: A total of 65 patients were treated with PEG-IFN alpha-2a/ribavirin (n=32) or PEG-IFN alpha-2b/ribavirin (n=33). PEG-IFN alpha-2a and PEG-IFN alpha-2b were administered at doses of 180 μg/week and 1.5 μg/kg/week, respectively, and ribavirin was administered orally at doses of 800-1200 mg. Patients with HCV genotype 1 and genotype non-1 were treated for 48 and 24 weeks, respectively. The treatment response was assessed based on the sustained virologic response (SVR). Results: The early virologic response (EVR), end-of-treatment response (ETR), and SVR were 70.0%, 52.0%, and 24.0%, respectively, in genotype 1 (n=50). In genotype non-1 (n=15), the ETR was 53.3% and the SVR was 33.3%. The overall SVR did not differ with genotype (1vs non-1, 24.0%vs.33.3%; P=0.471) or between decompensated cirrhosis and compensated cirrhosis (20.0%vs.27.3%, P=0.630). Ten patients developed cirrhotic complications during the treatment, and 11 stopped treatment due to treatment -related adverse events. Conclusion: The combination therapy of PEG-IFN and ribavirin exhibited a low efficacy in cirrhotic patients with HCV infection and was associated with frequent serious complications. However, with careful management of complications, the therapy may have a considerable efficacy in some patients with cirrhosis and HCV infection. (Korean J Hepatol 2010;16:38-48
