摘 要:目的探讨预防乙型肝炎病毒(HBV)相关性终末期肝病肝移植术后HBV再感染和复发的有效方法。方法对近5年来资料完整,术前存在HBV感染,术后存活超过6个月的183例成人肝移植患者的临床资料进行回顾性研究,按照用药方法,分为单纯使用拉米呋啶(LAM)组(单纯组)106例与联合使用小剂量乙型肝炎免疫球蛋白(HBIG)和LAM组(联合组)77例,全部得到随访。结果平均随访14.6个月,单纯组106例患者,移植后1周内HBsAg转阴率为82.1%(87/106),其中18例发现有HBV再感染,再感染率为16.98%(18/106),乙肝复发率为11.3%(12/106),9例检测到YMDD变异,变异率为8.49%。联合组77例患者移植后HBsAg转阴率为94.81%(73/77),HBV再感率为6.49%(5/77),HBV复发率为2.60%(2/77),1例检测到YMDD变异株,变异率为1.30%。移植后1周内HBsAg转阴率、HBV再感染率、复发率、YMDD变异率在两组间的差异均有统计学意义(P〈0.05)。对于出现YMDD变异株的患者加用阿德福韦(ADF)治疗取得了较好的效果。结论(1)小剂量HBIG和LAM联合应用较单纯使用LAM预防肝移植后HBV再感染和复发疗效确切,和国外大剂量静脉使用HBIG和LAM效果相当(x^2=0.306),且具有价格低廉,易于被国人接受的优点;(2)对于小剂量HBIG和LAM联合应用过程中出现YMDD变异引起LAM耐药的患者,应该加用ADF治疗。但是对于此类患者病例数较少,相关经验少,有待于临床进一步观察。Objective To investigate the effect of the regimen of lamivudine (LAM) combined with hepatitis B immunoglobulin (HBIG) in prevention and treatment of re-infection of hepatitis B virus (HBV) and recurrence of hepatitis B after orthotopic liver transplantation (OLT) for HBV related end stage liver disease. Methods The clinical data of 183 adult liver transplantation patients who lived more than 6 months and were followed up for 14.6 months with complete data were studied retrospectively. According to the HBV prevention strategy, these recipients were divided into two groups : group of pure LAM ( n = 106 ) and group of LAM plus intramuscular injection of low dose HBIG ( n = 77). Results The rate of HBsAg negative conversion 1 week after OLT of the LAM group was 82.10% (87/106) ,significantly lower than that of the LAM + HBIG group [94. 81% (73/77), P =0. 010]. The rates of HBV reinfection , HB recurrence, and YMDD mutation of the lamivudine group were 16.98% ( 18/106), 11.32% (12/106) ,and 8.49% (9/106) respectively, all significantly higher than those of the LAM + HBIG group [6.49% ( 5/77), 2.60% ( 2/77), and 1.30% (1/77) respectively, P = 0.035, 0. 028, and 0. 035 respectively ]. All the patients with YMDD mutation were treated with adefovir (ADF) with improvement. Analysis showed no obvious difference in the effect of LAM given intramuscularly or intravenously. Conclusion The protocol of combination of LAM and HBIG is highly effective, safe, and cost-effective in preventing the recurrence of HBV after OLT. YMDD mutation can be treated by ADF with satisfactory results.
