Abstract

Chronic hepatitis C virus infection (HCV) is a major comorbidity in patients with haemophilia. Peginterferon alpha and ribavirin is current standard anti-HCV therapy but there is little information about safety and efficacy of peginterferon alpha-2a and ribavirin combination therapy in these patients. In an open-label single-treatment arm cohort study, 367 haemophilia patients seronegative for hepatitis B and human immunodeficiency virus markers and chronically infected with HCV (HCV RNA>50 IU/ml for at least 6 months) received 180 microg of Pegasys and 800-1200 mg of ribavirin according to body weight. Genotypes 1 and 4, mixed and untypable infections were treated for 48 weeks, while genotypes 2 and 3 were treated for 24 weeks. The efficacy of therapy was expressed as sustained virological response (SVR). Two hundred and twenty-five subjects [61%, 95% confidence interval (CI) 56-66] achieved SVR, 66 patients relapsed and 30 subjects did not respond and nine patients developed breakthrough during treatment. In a multivariate logistic regression model, age<24 odds ratio (OR)=1.8 (95% CI 1.1-3.1), genotype non-1 OR=1.8 (95% CI 1.1-3.2), BMI<25 OR=2.1 (95% CI 1.3-3.3) and HCV RNA<600 000 IU/ml OR=1.7 (95% CI 1.1-3.2) were independ...Continue Reading
