Prior to 1990, many patients with inherited bleeding disorders were infected with hepatitis C virus (HCV). The aim of this study was to assess the risk of end stage liver disease (ESLD) in hemophilia patients with chronic hepatitis C. Patients were infected between 1961 and 1990, and were followed up to August 2005. Of 847 anti-HCV positive patients, 160 (19%) spontaneously cleared HCV and 687 (81%) developed chronic hepatitis C. Coinfection with HIV was present in 210 patients. After 35 years of infection the cumulative incidence of ESLD was 11.5% (95% C.I. 8.2-14.8%) in HIV negative patients and 35.1% (95% C.I. 29.2-41.0, p<0.001) in HIV co-infected patients. Independent risk factors of ESLD were: HIV co-infection (hazard ratio 13.8 [95% C.I. 7.5-25.3], older age at infection (hazard ratio 2.3 per 10 years [95% C.I. 2.0-2.8]), alcohol abuse (hazard ratio 4.9 [95% C.I. 2.5-9.6]), and presence of genotype 1 (hazard ratio 2.2 [95% C.I. 1.1-4.2]).
With longer duration of HCV infection, the risk of developing ESLD is emerging in patients with inherited bleeding disorders. Risk factors for rapid progression to ESLD are alcohol abuse, co-infection with HIV, older age at infection, and presence of genotype 1.
