HIV and HCV coinfection in haemophilia.

A substantial number of haemophilic patients are infected with both human immunodeficiency virus (HIV) and hepatitis C (HCV). HIV has been shown to accelerate the course of HCV chronic liver disease and there is evidence that HCV infection may worsen the prognosis of HIV. As many HIV infected patients are stable on highly active antiretroviral therapy (HAART) HCV should be actively managed in coinfected individuals. Pegylated interferon (Peg-IFN)/ribavirin combination therapy is the treatment of choice for HCV infection and should be considered in patients with stable HIV on or off HAART with CD4 counts >200 x 10(6)/l. Results of on-going trials of combination therapy in coinfected individuals are awaited. For coinfected patients with end stage liver disease who are stable on HAART liver transplantation should be considered.
