ObjectiveTo investigate the efficacy of lamivudine combined with low-dose hepatitis B immune globulin to prevent HBV reinfection after liver transplantation. MethodsThe clinical data of 76 cases of HBV-related liver disease after liver transplantation using lamivudine combined with low-dose hepatitis B immune globulin to prevent HBV re-infection were retrospectively analyzed, and the HBV re-infection risk factors were analyzed. ResultsSeventy-six patients' HBsAg became negative after liver transplantation, HBV re-infect in 9 cases.The re-infection rate was 9.2% (7/76) and 11.8% (9/76), respectively, in 1-year and 2-year after liver transplantation. ConclusionsLamivudine combined with low-dose hepatitis B immune globulin after liver transplantation can be effective preventing re-infection with HBV.HBeAg positive and HBV-DNA positive before liver transplantation is risk factors of HBV re-infection.
Objective To assess the efficacy of telbivudine in the treatment of chronic hepatitis B (CHB). Methods Randomized controlled trials (RCTs) of telbivudine therapy vs. lamivudine therapy in both Chinese and English were retrieved from seven electronic databases with a cut-off date in February 2010, including PubMed, EMbase, VIP, CBM, CNKI, and The Cochrane library. The meta-analyses and evaluation on methodology quality were performed for the included studies. Results Two RCTs as Grade-A study were included. The meta-analyses showed that telbivudine was superior to lamivudine in aspects of therapeutic response (RR=1.28, 95%CI 1.10 to 1.48, P=0.001), ALT normalization (RR=1.12, 95%CI 1.01 to 1.23, P=0.02), and PCR-negative HBV DNA or below the lower limit (RR=1.44, 95%CI 1.36 to 1.53, Plt;0.000 01), primary treatment failure (OR=0.28, 95%CI 0.18, to 0.43, Plt;0.000 01), viral breakthrough (OR=0.38, 95%CI 0.32 to 0.47, Plt;0.000 01) and viral resistance (OR=0.44, 95%CI 0.36 to 0.55, Plt;0.000 01). Conclusion Based on the current clinical evidence, telbivudine demonstrates superiority in comparison with lamivudine on all direct measures of antiviral efficacy for CHB. Because of the short follow-up duration and the small sample size of the included studies, it is expected to further discuss the long-term efficacy.

目的 采用干扰素和阿德福韦酯治疗慢性乙型肝炎患者经拉米夫定治疗后出现YMDD变异，比较两种治疗策略的临床疗效。 方法 选择2002年2月-年12月经100 mg拉米夫定治疗后出现YMDD变异的慢性乙型肝炎患者76例。其中，男52例，女24例；年龄18~55岁，平均年龄33岁。服用100 mg拉米夫定52～156周发生YMDD变异，HBV DNA低于治疗前水平，丙氨酸转移酶(alanine aminotransferase，ALT)lt;2×ULN/L患者分为A组(26例)，继续用100 mg拉米夫定治疗48周；服用100 mg拉米夫定52～156周发生YMDD变异，HBV DNA定量检测高于或等于治疗前水平，ALTgt;2×ULN/L，根据患者自愿分为B组(27例)和C组(23例)。B组用100 mg拉米夫定联合10 mg阿德福韦酯治疗48周；C组用干扰素治疗48周。分别观察3组ALT复常率及HBV DNA转阴率、HBeAg阳性患者血清学转换率。 结果 治疗48周时，B、C组患者ALT复常率分别是74.1%和78.3%，明显高于A组的34.6%，差异有统计学意义(Plt;0.05)；B、C组患者HBV DNA转阴率分别是77.7%和73.9%，明显高于A组的11.5%，差异有统计学意义(Plt;0.05)；3组HBeAg阳性患者血清学转换率比较，差异均无统计学意义(Pgt;0.05)。 结论 慢性乙型肝炎患者经拉米夫定治疗后出现YMDD变异，继续用拉米夫定治疗疗效不理想，改用干扰素或联合阿德福韦酯治疗更安全有效。
目的 比较拉米夫定+阿德福韦酯联合治疗与阿德福韦酯单药治疗对阿德福韦酯停药后出现病毒学反弹而无基因型耐药变异患者的疗效及安全性。 方法 回顾研究2007年1月－2012年1月在传染科门诊就诊的67例阿德福韦酯治疗获得病毒学应答但停药后出现病毒学反弹的e抗原阳性慢性乙型肝炎患者，分别给予拉米夫定+阿德福韦酯联合治疗（联合组，n=35）和阿德福韦酯单药治疗（单药组，n=32）。 结果 治疗1年后，联合组（32例，85.7%）较单药组（21例，65.6%）有更多的患者重新获得了丙氨酸转氨酶复常（P=0.009），联合组34例（97.1%）乙型肝炎病毒DNA阴转，单药组22例（68.8%）阴转，两组差异有统计学意义（P=0.002）；在血清学转换方面，联合组和单药组分别有4例（11.4%）和1例（3.1%）患者获得了e抗原的血清学转换。在治疗中所有患者均未发生任何严重不良反应。 结论 阿德福韦酯停药后出现病毒学反弹，选择拉米夫定与阿德福韦酯联合治疗可使患者重新获得较好的生化学和病毒学应答。
ObjectiveTo explore the effectiveness of lamividine (LAM) combined with adefovir (ADV) versus entecavir (ETV) for lamivudine-resistant (LAM-R) hepatitis B in renal transplant recipients. MethodOutpatients and inpatients of lamivudine-resistant kidney graft recipients with chronic hepatitis B admitted to West China Hospital and the People's Hospital of Santai County during Jan 2007 to Mar 2012 were divided into A group (LAM+ADV) and B group (ETV). And the level of alanine aminotransferase (ALT), level of serum creatinine, HBV serological markers and HBV-DNA load were compared by SPSS 16.0 software. ResultsA total of 15 patients were included. The mean age was 36.7±6.6 years old, the majority of patients were male. After treatment for 4 weeks, 12 weeks, 24 weeks, 48 weeks, 96 weeks, no significant differences were found between two groups in liver function normalization rates, the HBV-DNA negative conversion rates and serum creatinine level. ConclusionsLAM add-on ADV combination therapy and ETV monotherapy were both safe and effective in LAM-R kidney transplants with CHB, but the load of HBV-DNA in some patients were still positive at the endpoint. Elevated serum creatinine level may occur in some patients who treated with ADV. Consequently, for HBsAg-positive kidney transplantation patients, those anti-HBV drugs that are more effective, safer and less resistant may be better in the beginning of treatment.
【Abstract】Objective To investigate the prevention and treatment for recurrence of hepatitis B after liver transplantation on HBV-related diseases. Methods Making a literature summarization based on published papers review.Results Acute and chronic HBV-related diseases are the main indications of liver transplantation.Recurrence rate of hepatitis B is from 80% to 100% in the untreated patients after liver transplantation,and it affects the survivals of patients seriously.It has become a focus to prevent and treat the recurrence of hepatitis B.After a series of explotation and application,there have been a lot of drugs of preventing and treating HBV reinfection, including hepatitis B immunoglobulin,interferon and nucleotide analog antivirus drugs(lamivudine, famcyclovir, adefovir),etc.The therapeutic characteristics of them are different. Their utilizations of dividing or alliance are developing rapidly.Conclusion Liver transplatation is an effective therapy for HBV-related disease. Anti-HBV treatments perioperation play an important role in the improvement of succeed of liver transplantation.
Objective To evaluate the efficacy and safety of antiviral drugs for hepatitis B with YMDD motif variant. Methods We electronically searched MEDLINE (1989-April, 2004), EMBASE (1989-April, 2004), CBMdisc (expand) (1989-April, 2004), and handsearched unpublished Chinese conference proceedings. Randomized and quasi-randomized trials in patients with chronic hepatitis B with YMDD motif variant correlative to lamivudine were collected. Two reviewers extracted the data and assessed the quality of literature independently. The data were then analyzed by RevMan 4.2 software. Results Five studies involving 6 trials and 284 patients were included. According to the results of meta-analysis, antiviral therapy with adefovir plus lamivudine showed significantly better effects on the clearance of serum HBV-DNA and HBeAg and normalization of ALT than that of lamivudine alone (RR 16.61, 95%CI 2.29 to 120.71; RR 6.66, 95%CI 1.23 to 35.88 and RR 6.26, 95%CI 2.29 to 17.12 respectively); also, oxymatrine plus thymothin showed obviously better effects on the clearance of serum HBV-DNA and HBeAg (RR 2.96, 95%CI 1.26 to 6.93 and RR 2.51, 95%CI 1.05 to 5.98 respectively).But adefovir alone showed no better effects on clearance of serum HBV-DNA and HBeAg than that of lamivudine alone (RR 11.00, 95%CI 0.65 to 186.02 and RR 7.00, 95%CI 0.39 to 126.92 respectively); interferon plus lamivudine showed no better effects on the clearance of serum HBV-DNA, HBeAg and the normalization of ALT (RR 3.50, 95%CI 0.90 to 13.58; RR 4.90, 95%CI 0.70 to 35.10 and RR 2.80, 95%CI 0.91 to 8.12 respectively). Chinese herbs plus lamivudine showed no better effects on the clearance of serum HBV-DNA (RR 1.16, 95%CI 0.89 to 1.51). There were no significant side effects in the groups, except flu like symptom in the interferon group, slight kidney impairment in the adefovir group, and aggravation of rare cases in lamivudine group. Conclusions Antiviral therapy with adefovir plus lamivudine, or oxymatrine plus thymothin, shows better effects than with lamivudine alone in terms of antiviral therapy and clinical outcome improvement. However, the evidence is too weak to draw a definite conclusion in this systematic review. Larger sample size and rigorously designed randomized, double blind, placebo control trials are required for future study.
