Liver transplantation is the only effective treatment for hepatitis B virus (HBV)-related end-stage liver disease. However, without antiviral prophylaxis, the recurrence rate of hepatitis B is as high as 80%-100%, which leads to a 50% mortality rate in the first 2 years after liver transplantation. Combination therapy of hepatitis B immunoglobulin (HBIG) and lamivudine demonstrated a higher efficacy of prophylaxis and further reduced the rate of recurrence to < 10%. The strategy of HBIG combined with lamivudine has been the standard treatment in many centers. However, the high rate of lamivudine resistance and the many disadvantages of HBIG have compelled surgeons to reconsider the long-term efficacy of this strategy for the prevention of HBV reinfection. Recently, new nucleos(t)ide analogues, such as entecavir and tenofovir, have been approved as first-line monotherapies for the treatment of chronic hepatitis B infection. These antiviral medicines have replaced lamivudine as the first choice in the prevention of HBV recurrence after liver transplantation. Various therapies that are composed of entecavir, tenofovir, and lamivudine plus adefovir, with or without HBIG have been adopted in several liver transplant centers. This article reviews the recent advances in prophylaxis for the recurrence of hepatitis B after liver transplantation.
肝移植是治疗乙型肝炎病毒(HBV)相关终末期肝病的唯一有效方法。然而,若无抗病毒预防措施,乙肝复发率高达80%-100%,这导致肝移植后前两年的死亡率达50%。乙肝免疫球蛋白(HBIG)与拉米夫定联合治疗显示出更高的预防效果,并进一步将复发率降至<10%。HBIG联合拉米夫定策略已成为许多中心的标准治疗方法。然而,拉米夫定的高耐药率以及HBIG的诸多缺点促使外科医生重新考虑该策略预防HBV再感染的长期疗效。最近,新型核苷(酸)类似物,如恩替卡韦和替诺福韦,已被批准作为治疗慢性乙型肝炎感染的一线单药疗法。这些抗病毒药物已取代拉米夫定,成为预防肝移植后HBV复发的首选药物。多个肝移植中心采用了由恩替卡韦、替诺福韦以及拉米夫定加阿德福韦组成的各种疗法,有的还联合使用了HBIG。本文综述了肝移植后乙肝复发预防的最新进展。
