Chronic infection with hepatitis C virus is very frequent among hemophilic patients in all developed counties, including the Czech Republic. Because of a possibility of developing serious terminal stages of infection, liver cirrhosis and hepatocellular carcinoma, the tendency in treatment of patients with chronic hepatitis C is to start it as soon as possible and thus reduce the probability of developing these advanced stages of disease which are difficult to treat. Treatment of hemophilic patients with chronic hepatitis C started in the Department of Infectious Diseases, University Hospital Brno Bohunice, in 1996. Used treatment schemes have reflected historical evolution of treatments used to treat chronic hepatitis C. Initially, alpha-interferon (IFN) was administered in monotheraphy (6 patients), later, since 1999, a combination of alpha-IFN and ribavirin was administered (13 patients), and since 2001 a combination of pegylated interferon (PEG-IFN) and ribavirin (3 patients) was administered. In all the patients the individual treatments took 12 month. Sustained negativization of HCV RNA in serum has not been achieved in any patient treated only with alpha-IFN. In patients who were administered the combination of alpha-IFN and ribavirin this effect appeared in 4 from 7 cases without history of treatment with alpha-IFN (57%), one from 2 relapses and one from 3 non-responders. The combination PEG-IFN and ribavirin was effective in the only one patient who relapsed after alpha-IFN and ribavirin and in one from the two non-responders to this combination. The tolerance and safety of treatment was good in haemophilia patients and could be fully compared to those in other patients with chronic hepatitis C.
