ABSTRACT

OBJECTIVE: The natural history of mild chronic hepatitis C is not well-known and the benefit of treating this form of the disease is not well-defined. We conducted a pilot study to answer this question. DESIGN: Mild chronic hepatitis C was defined by positivity for anti-HCV antibodies, detectable serum HCV RNA by PCR, and a Knodell score < or = 5 on a liver biopsy performed within the previous 6 months. Eighty patients from six centres were randomized into two groups receiving interferon alpha-2b, 3 MU three times a week for 6 months (group 1, n = 39) or no treatment (group 2, n = 41). Sustained response was defined by the loss of detectable serum HCV RNA at 6 months after therapy. RESULTS: The two groups were not different at entry with respect to age, sex ratio, source of infection, disease duration, genotype, viral load and Knodell score. One patient (group 1) was excluded from the study, while two patients in group 1 (5%) and seven in group 2 (17.1 %) did not complete the trial. A sustained response was observed in seven patients (18%) in group 1 versus none in group 2 (P < 0.01). The difference in mean Knodell score remained non-statistically significant between the two groups at the end of the study. Reduction or interruption of interferon was necessary in eight patients (24.2%). CONCLUSIONS: This first randomized controlled study in mild chronic hepatitis C shows a proportion of sustained responders to interferon alpha-2b similar to that observed in active chronic hepatitis C.

ABSTRACT

BACKGROUND & AIMS: Liver transplantation for hepatitis C virus (HCV)-related liver disease is characterized by frequent graft infection by HCV. The prognosis and risk factors for morbidity and mortality in this condition were determined. METHODS: A retrospective study of 652 consecutive anti-HCV-positive patients undergoing liver transplantation between 1984 and 1995 in 15 European centers was conducted; 102 patients coinfected with hepatitis B virus (HBV) received immunoglobulin prophylaxis for antibody to hepatitis B surface antigen. RESULTS: Overall, 5-year survival was 72%. Five-year actuarial rates of hepatitis and cirrhosis were 80% and 10%. Genotypes 1b, 1a, and 2 were detected in 214 (80%), 24 (9%), and 24 (9%) of 268 patients analyzed. The only discriminant factor for patient or graft survival was hepatocellular carcinoma as primary indication. Independent risk factors for recurrent hepatitis included the absence of HBV coinfection before transplantation (relative risk [RR], 1.7; 95% confidence interval [CI], 1.2-2.6; P = 0.005), genotype 1b (RR, 2; 95% CI, 1.3-2.9; P = 0.01), and age > 49 years (RR, 1.4; 95% CI, 1.1-1.8; P = 0.01). CONCLUSIONS: The results of transplantation for HCV-related disease are compromised by a significant risk of cirrhosis, although 5-year survival is satisfactory. Genotype 1b, age, and absence of pretransplantation coinfection by HBV are risk factors for recurrent HCV.
