Abstract

Treatment with pegylated interferon (Peg-IFN) and ribavirin, now the standard of care, has been shown to achieve sustained viral response (SVR) in up to 60% of patients with hepatitis C (HCV). Studies of response to this combination in HCV-infected haemophilia patients are scarce. The aim of the study was to report the results and safety of interferon/ribavirin treatment in HCV and HCV-/HIV-infected patients at the Israeli National Hemophilia Center. A retrospective observational cohort study was conducted on haemophilia patients infected with HCV or HCV/HIV. Patients received combination of Peg-IFN and ribavirin. Few were still treated with standard interferon. The primary end-point was sustained viral response (SVR). The secondary end-point was safety, with emphasis on increased bleeding episodes. Some 18/43 (42%) HCV mono-infected haemophilia patients achieved SVR. Relapse occurred in 14 (33%), while 11 patients (25%) were non-responders. SVR was achieved among 17/37 (46%) naïve patients receiving Peg-IFN and ribavirin. Among patients with genotype-1, SVR was achieved in 12/36 (33%) and 11/30 (37%) in the whole group and Peg-IFN treated naïve patients, respectively. In HCV/HIV co-infected patients only 1 patient achieved SVR. Severe anaemia occurred in 14/50 (28%) patients, four received erythropoietin. None maintained stable haemoglobin levels. Two patients had significant bleeding episodes. In our cohort of haemophilia patients, SVR was achieved in a lower than expected rates. A relatively high relapse rate in the HCV mono-infected patients and a very high non-response rate in the HCV/HIV co-infected patients were observed as anticipated. Anaemia was a major side effect and the use of growth factors seemed unrevealing.
