    Abstract:
    OBJECTIVE: To investigate the efficacy of early antiviral treatment for hepatitis C virus (HCV) recurrence in HIV/HCV-coinfected patients undergoing liver transplantation for end-stage liver disease. METHODS: Open prospective trial of early treatment of HCV recurrence in consecutive HIV/HCV-coinfected patients transplanted at a tertiary hospital in Barcelona between 2002 and 2004. All patients had indication for liver transplantation, no previous CDC class C HIV-associated opportunistic events, a CD4+ T-cell count >100cells/microl, and undetectable plasma HIV RNA on highly active antiretroviral therapy. Treatment with pegylated interferon-alpha2b (1.5 microg/kg/week) and ribavirin (800-1000 mg/day) was given for 24 to 48 weeks, as soon as HCV recurrence was histologically documented. RESULTS: Of six patients who underwent transplant, five patients surviving the early post-transplantation period developed HCV recurrence, presenting as severe cholestatic hepatitis in three, and were started on antiviral treatment a median of 12 weeks (range: 5-31) after transplantation. After a median follow-up of 24 months all treated patients were alive. Biochemical response was achieved in all patients, although only one achieved a sustained virological response. Mild rejection before HCV recurrence occurred in two cases. Treatment was well tolerated with no episodes of rejection or mitochondrial toxicity. No patient required modification of the antiretroviral regimen. Liver biopsies performed in patients without virological response, 12-34 months after transplantation, showed cirrhosis in two and moderate chronic active hepatitis in the remainder. CONCLUSIONS: Despite early antiviral treatment, severe HCV recurrence after liver transplantation may compromise long-term survival in HIV-infected patients. Improved treatment strategies for these patients are urgently required.
