Background and goals

The slow progression of chronic hepatitis C (CHC) infection requires long observation periods to detect clinical changes. We compare the incidence of clinical events, hepatocellular carcinoma (HCC), overall mortality, liver-related mortality, and fibrosis progression between patients with a sustained virological response (SVR) and nonresponders (NR) after a 13-year follow-up period.


One hundred and eighty-two CHC patients, who received interferon and ribavirin treatment between 1996 and 2000, were included. Clinical events were evaluated during follow-up. At the end of follow-up, transient elastography was used to assess fibrosis progression.


Of the 182 patients, 46.7% (n=85) achieved an SVR. Twenty-seven patients developed hepatic decompensation (one SVR) and 15 developed HCC (three SVR). Twenty-nine patients died (eight SVR). Twelve of the 29 deaths were liver related (two SVR). Independent factors associated with hepatic decompensation were NR to treatment [hazard ratio (HR)=23.35; 95% confidence interval (CI): 2.90–189.25; P=0.003], advanced fibrosis at baseline (HR=9.11; 95% CI: 4.13–20.09), and treatment delay after diagnosis (HR=1.02; 95% CI: 1.00–1.03; P=0.012). Only the latter two were associated with HCC development and liver-related mortality. An assessment of liver fibrosis was performed on 125 patients (66 SVR). Fibrosis values were significantly lower in SVR patients, showing less progression to advanced stages of fibrosis [SVR: 6.6 (2.8); 95% CI: 5.8–7.3] than NR [NR: 14.0 (11.1); 95% CI: 11.1–16.9; P<0.001].


In patients with CHC, SVR is durable and reduces clinical events. The risk of HCC development is lower, but not eliminated. Sustained responders showed fibrosis stabilization or improved fibrosis values.
