    Abstract:
    Liver transplantation for hepatitis B represents 5-10 % of all liver transplantations performed in Europe. The prognosis after liver transplantation is related to the efficacy of prophylaxis of HBV graft reinfection. The risk of HBV reinfection is directly related to the HBV viral load at transplantation. HBV prophylaxis after transplantation with long-term administration of anti-HBS immune globulins (HBIG) or with monoprophylaxis with lamivudine can reduce significantly the risk of HBV recurrence mainly in patients without active HBV replication. Antivirals such as lamivudine, adefovir, entecavir or tenofovir can control HBV replication in patients with decompensated HBV cirrhosis waiting for transplantation. However, there is a risk of HBV viral breakthrough during nucleo (t) side antiviral treatment. The use of an antiviral alone or in combination should take into account the antiviral efficacy and the risk of viral resistance. The post-transplant combination of antiviral therapy and HBIG prophylaxis is very effective in reducing the rate of HBV reinfection to less than 10 % even in patients with HBV replication at transplantation. In the absence of active viral replication at transplantation, the possibilty to discontinue HBIG prophylaxis at long-term after transplantation with maintenance of antiviral treatment or HBV vaccination is in evaluation. The use of new antiviral therapies (nucleos(t)ide analogues) has dramatically improved the prognosis of patients with HBV reinfection of the graft. The current 5-year survival after liver transplantation for HBV related liver disease is 85 %. In conclusion, the prophylaxis of HBV reinfection combining antiviral therapy prior to transplantation, and combination of HBIG and antiviral therapy post-transplantation is effective in reducing the rate of HBV reinfection to less than 10 %.
