肝移植后乙型肝炎病毒再感染的预防与治疗

目的；研究肝移植后再感染的预防和治疗。方法：19例患者包括慢性乙型重型肝炎，终末期肝硬化和肝硬化合并肝癌患者，移植前，后给予抗,乏昔洛韦4例，拉米夫定13例，拉米夫定＋乙型肝炎免疫球蛋白（HBIg) 2例，观察临床表现，血HBV M及肝活检免疫组织化学等指标。结果：应用乏昔洛韦治疗的4例患者全部再感染，血清HBsAg,HBeAg和HBV DNA均阳性，3例患者肝活检免疫组织化学表现有HBsAg ,HBcAg表达，随病程延长而增多。1例发生了典型病毒性肝炎发病。4例中3例死亡，拉米夫定的治疗组13例，经治疗后仅有7例HBsAg阳性，2例HBV DNA阳性，4例肝组织免疫组织化学有HBsAg或HBcAg表达，治疗中1例有肝炎复发。拉米夫定＋HBIg治疗2例患者1例血清抗－HBc阳性，另1例HBV M均阴性。免疫组织化学检测亦未见阳性结果。结论：HBV感染相关疾病终末期肝病应作为肝移植的适应证，肝移植后抗病毒治疗可预防再感染，改善再感染者的预后。

Prevention and treatment of HBV reinfection following liver transplantation

Objective To study the prevention and treatment of HBV reinfection after liver transplantation. Methods Total 19 cases of chronic fulminant hepatitis H, the end-stage of liver cirrhosis and liver carcinoma complicated with HIBV cirrhosis. Were performed liver transplantation and given anti-viral drugs pre and post transplantation. Famciclovir was administered in 4 cases, lamivudine in 13 cases and lamivudine+HBIg in 2 cases. The serum HBVM and liver biopsy immunohistochemistry were performed. Results Four cases given famciclovir developed reinfection. Serum HBsAg, HBeAg and HIBV DNA were positive in 3 cases. Liver biopsy immunohistochemistry showed HBsAg and HBeAg phenotype. Classical viral hepatitis in 1 case occurred, three cases died. In the lamivudin group 7 cases showed positive for HBsAg, 2 cases positive for HIBV DNA, 4 cases HBsAg or HBcAg phenotype. One case showed positive for serum antiHBc the other negative for HIBVM, and liver biopsy immunohistochemistry was negative too. Conclusions These date suggest that anti-virus prevention and treatment in pre and post liver transplantation with HEY infected correlative disease is necessary, feasible and effective.
