Aim: To assess the benefit risk ratio of interferon and ribavirin in the treatment of patients with post hepatitis C cirrhosis we summarize the spontaneous over mortality of this disease, and made an overview of the randomized trials and of other controlled studies.
Results: In comparison to controls, patients with post hepatitis C cirrhosis have a 17 fold increase risk of dying from a liver disease that a control population, and a 6 fold increase from primary liver cancer. In France the hepatitis C epidemic which start in the sixties explains now the observed dramatic increase in mortality by primary liver cancer, both in men and women. Meta-analysis of randomized trials and controlled retrospective studies showed that interferon treatment is associated with a significant increase in ALT response at the end of the treatment, with a decrease in hepatocellular incidence as well as a decrease in mortality in comparison with controls. Very few data are published concerning ribavirin alone or in combination with interferon in patients with cirrhosis. Preliminary data suggest that this combination during 48 weeks permit to obtain in patients with compensated cirrhosis 20% of sustained virological response. The safety was acceptable but patients with low initial blood cells count must be carefully followed. In conclusion this overview clearly demonstrates a benefit-risk ratio in favor of treatment in patients with post hepatitis C cirrhosis by interferon.
