    Abstract:
    BACKGROUND AND AIMS: In patients with terminal Hepatitis B Virus-related liver diseases, liver transplantation carries a consistent risk of Hepatitis B Virus recrudescence in the graft. In the attempt to reduce the reinfection rate with antiviral therapy, we studied a total of 16 viraemic patients. PATIENTS AND METHODS: Twelve patients received Ganciclovir, starting 4-67 days (mean 25 days) before transplantation and prolonged for 10 days after transplantation; four patients were treated with Lactosaminated Arabinoside-Monophosphate 6 hours before surgery and prolonged for 28 days after surgery. All received hepatitis B immunoglobulins. RESULTS: At transplantation, HBV-DNA had decreased to about 10(4) virus/ml (as assessed by the polymerase chain reaction assay) in 10 of the 12 patients treated with Ganciclovir. Of these patients, 4 died perioperatively from causes unrelated to Hepatitis B Virus reinfection. Of the eight survivors, only the patient who maintained a titre of 10(6) virus/ml at the time of transplantation developed viral recurrence 4 months after surgery. Before transplantation, 2 of the patients treated with Lactosaminated Arabinoside-Monophosphate had a viraemic load of 10(6) and 2 of 10(4) virus/ml. In all cases, viraemia became undetectable at the end of therapy. None died and Hepatitis B Virus recurred 2 months after transplantation in one. The overall rate of Hepatitis B Virus recurrence was 16.6%. The recurrence rate decreased to 9% in patients in whom the viraemic load decreased to around 10(4) virus/ml following treatment, compared to an overall recurrence rate of 50% in our historical series of patients transplanted for Hepatitis B Virus-related cirrhosis. CONCLUSION: Antiviral therapy was effective in decreasing the risk of Hepatitis B Virus reinfection of the liver graft by decreasing the viral load before surgery.
