Abstract
Hepatitis B virus (HBV)-related liver disease is the leading indication for liver transplantation (LT) in Asia, especially in China. With the introduction of hepatitis B immunoglobulin (HBIG) and oral antiviral drugs, the recurrent HBV infection rate after LT has been evidently reduced. However, complete eradication of recurrent HBV infection after LT is almost impossible. Recurrent graft infection may lead to rapid disease progression and is a frequent cause of death within the first year after LT. At present, the availability of new oral medications, especially nucleoside or nucleotide analogues such as adefovir dipivoxil, entecavir and tenofovir disoproxil fumarate, further strengthens our ability to treat recurrent HBV infection after LT. Moreover, since combined treatment with HBIG and antiviral agents after liver re-transplantation may play an important role in improving the prognosis of recurrent HBV infection, irreversible graft dysfunction secondary to recurrent HBV infection in spite of oral medications should no longer be considered an absolute contraindication for liver re-transplantation. Published reviews focusing on the therapeutic strategies for recurrent HBV infection after LT are very limited. In this article, the current therapeutic strategies for recurrent HBV infection after LT and evolving new trends are reviewed to guide clinical doctors to choose an optimal treatment plan in different clinical settings.

Abstract
OBJECTIVE To review the prophylaxis against post-liver transplantation hepatitis B reinfection with anti-hepatitis B immunoglobulin and nucleoside analogues. METHOD A bibliographic search was carried out using Pubmed, entering the following key words: hepatitis B and liver transplantation and (hepatitis B hyperimmune globulin and lamivudine and adefovir dipivoxil) up to June 2006. The initial search was filtered using the terms clinical trial, randomized clinical trial and review. The data contained in selected studies were reviewed. RESULTS A total of 53 works were found. Prophylaxis with anti-HB immunoglobulin and lamivudine is the best strategy for avoiding recurrence of the hepatitis B virus in patients undergoing hepatic transplants; achieving very low reinfection rates (0-10%) with follow up periods of between 1-5 years. There is a great degree of variability (dose, duration and method of HBIg administration) in the prophylactic protocols reviewed. The use of low doses of anti-HB immunoglobulin (administered intravenously followed by intramuscular administration, or administered intramuscularly from the anhepatic stage), and lamivudine in patients who receive transplants with a low risk of recurrence, shows prophylactic efficacy comparable to the use of high doses of anti-HB immunoglobulin. Furthermore, it implies a considerable reduction in costs. CONCLUSIONS The availability of suitably designed clinical trials is required to design a more cost-effective protocol and reduce variability.

Abstract
Strategies using lamivudine and hepatitis B immunoglobulins (HBIg) for prevention of hepatitis B virus (HBV) reinfection after liver transplantation (LT) are expensive since life-long treatment is needed. We evaluated the possibility to obtain protective hepatitis B surface antigen (HBsAg) antibody (anti-HBs) titers after LT and to discontinue HBIg prophylaxis after a reinforced course of vaccination against HBV using an experimental adjuvant HBsAg / AS04 vaccine (GlaxoSmithKline Biologicals [GSK], Rixensart, Belgium) in patients transplanted for hepatitis B. Fifteen LT patients on stable low-level immunosuppression were vaccinated with a double dose of the vaccine at 0, 1, 2, 6, and 12 months: 5 patients were transplanted for nonviral diseases and 10 patients were transplanted for HBV on HBIg monotherapy. HBIg were continued during baseline vaccination (0, 1, and 2 months) and when anti-HBs titers determined every 6 weeks dropped below 150 IU/L. Overall follow-up was 18 months. Sustained long-term response to vaccination was defined as anti-HBs titers >500 IU/L without further need for HBIg administration during a follow-up period of at least 12 months. Overall sustained response to vaccination was 53% (8 / 15 patients); 80% (4 / 5 patients) in the nonviral disease group and 40% (4 / 10 patients) in the HBV group (2 /2 fulminant and 2/8 chronically infected patients) developed a sustained long-term response and were completely free of HBIg at the end of the 18-month follow-up. No HBV recurrence, rejection episodes, or side effects occurred during the follow-up. In conclusion, protective anti-HBs titers were obtained in a substantial number of LT patients following a reinforced course of HBV vaccination with vaccines containing new immunostimulating adjuvants. Vaccination seems well tolerated and safe and allows long-term discontinuation of HBIg.

Abstract
Chronic HBV infection is a common cause of advanced liver disease that is associated with substantial mortality. Furthermore, chronic hepatitis B was historically a controversial indication for liver transplantation because of a low post-transplant survival, with graft infection being the major contributor to adverse outcomes. The initial use of hepatitis B immune globulin as prophylaxis, followed later by combined therapy with lamivudine, markedly reduced viral recurrence and improved the survival of patients transplanted for acute or chronic hepatitis B with liver failure. Lamivudine alone can also be used for long-term prophylaxis against de novo HBV infection that can be transmitted by organs from donors positive for anti-HBc or anti-HBs. When used in patients with decompensated chronic hepatitis B with cirrhosis, lamivudine has been shown to improve clinical manifestations, prolong pretransplant survival, and defer, or even obviate, the need for transplantation. Despite prophylaxis, viral mutations with breakthrough reinfection may occur and lead to liver failure. The recently approved adefovir dipivoxil, which is active against lamivudine-resistant mutation, and other nucleoside analogs that are in various phases of development, offer hope as rescue therapy for viral recurrence. Other therapeutic alternatives in the future may include gene therapy and immune interventions.

Abstract
Long-term immunoprophylaxis with hepatitis B immune globulin (HBIG) is widely accepted for the prevention of recurrent hepatitis B virus (HBV) infection after liver transplantation in HBV-infected patients without viral replication. We report long-term results of HBIG administration in 284 hepatitis B surface antigen (HBsAg)-positive transplant patients. In protocol 1, 259 patients were given HBIG with the goal of maintaining the anti-HBs antibody (Ab) titer over 100 IU/L. After December 1993, 25 HBV DNA-positive patients received HBIG, with a target anti-HBs Ab titer over 500 IU/L, combined with posttransplantation antiviral therapy (protocol 2). At 10 years, 44 patients without recurrence were tested for the presence of HBV DNA in serum using real-time polymerase chain reaction (PCR); 28 were also tested in liver and peripheral blood mononuclear cells (PBMC). The overall 5- and 10-year posttransplantation actuarial rates of HBV recurrence were 24.2% and 25.4%, respectively. The 5-year recurrence rate in protocol 2 patients was 11.8%. On multivariate analysis, predictors of lower HBV recurrence risk were absence of serum HBV DNA before transplantation (P <.0001), acute liver disease (P =.0037), HDV superinfection (P =.012), and protocol 2 therapy (P <.0001). Low-level HBV DNA was detected by PCR in 45.4% of patients without HBV recurrence at 10 years. Overall actuarial 10-year survival was 74.4%. In conclusion, we confirm the efficacy of long-term HBIG immunoprophylaxis. Combination prophylaxis with HBIG and antiviral therapy is effective in patients with viral replication. Although there were only a few cases of HBV recurrence after 5 years, HBV DNA remained present in 45% of patients at 10 years.

Abstract
1. Patients undergoing orthotopic liver transplantation (OLT) for hepatitis B without effective prophylaxis have a high risk for recurrent infection and severe graft damage, leading to death or re-OLT. 2. Long-term prophylaxis with hepatitis B immune globulin (HBIg) significantly reduces the risk for hepatitis B virus (HBV) recurrence and increases survival. Patients with detectable HBV DNA at the time of OLT have a high risk for recurrence despite HBIg prophylaxis. 3. Lamivudine (LAM) therapy for patients with decompensated HBV cirrhosis before OLT results in inhibition of viral replication and clinical improvement. Its efficacy is limited by the frequent emergence of LAM-resistant YMDD mutations. The ideal length of therapy with LAM pre-OLT has not yet been defined. 4. Prophylaxis of HBV recurrence with LAM monotherapy is not recommended because of the reappearance of hepatitis B surface antigen after OLT in approximately 50% of patients. 5. LAM is the best available treatment for patients with established recurrent hepatitis B. Long-term therapy is associated with the emergence of drug-resistant mutants in up to 60% of patients. Severe hepatitis and liver failure have been described among liver transplant recipients with YMDD mutations. 6. Combination therapy with HBIg and LAM prevents HBV recurrence in 90% to 100% of patients who undergo OLT for hepatitis B. The optimal HBIg protocol in the LAM era is yet to be defined. 7. Preliminary studies suggest that adefovir dipivoxil inhibits HBV replication in patients infected with LAM-resistant HBV strains. 8. Fifteen years ago, hepatitis B was regarded as a relative or absolute contraindication for OLT. Today, hepatitis B is a universally accepted indication for OLT.

Abstract
Retransplantation already accounts for 10% of all liver transplants performed, and this percentage is likely to increase as patients live long enough to develop graft failure from recurrent disease. Overall, retransplantation is associated with significantly diminished survival and increased costs. This review summarizes the current causes of graft failure after primary liver transplant, prognostic models that can identify the subset of patients for retransplantation with outcomes comparable to primary transplantation, and ethical considerations in this setting, i.e., outcomes-based versus urgency-based approaches.

Abstract
Advances in immunosuppressive therapy, operative techniques, and perioperative management have resulted in long-term patient survival rates approaching 90% following liver transplantation for chronic viral hepatitis. The increasing number of referrals for liver transplantation reflects the impact of chronic HCV infection as a cause of end-stage liver disease. Unlike hepatitis B, there is still no effective treatment in preventing recurrent hepatitis C after liver transplantation. The spectrum of allograft injury related to universal HCV infection recurrence ranges from no evidence of histologic injury to mild inflammation to severe disease with allograft failure in small proportion of patients. Various factors may explain these differing outcomes, including degree of pretransplantation viremia, HLA compatibility, presence of more pathogenic HCV genotypes, integrity of cellular immune response, and type of immunosuppression. Fortunately, patient survival does not seem to be affected short-term; the long-term outcome of liver transplantation for chronic hepatitis C is unclear but is likely to be decreased. Combination therapy with interferon plus ribavirin seems to be a promising treatment strategy for posttransplantation recurrent hepatitis C, and the use of pegylated interferon plus ribavirin may improve these results. Patients with moderate to severe allograft hepatitis are appropriate candidates for combination antiviral therapy. Histopathologically documented recurrent hepatitis C in liver transplant recipients is associated with impaired quality of life, inferior physical condition, and a higher incidence of depression compared with patients who did not have HCV and in those without HCV recurrence. In conclusion, it is possible that the continued improvements in antiviral therapy against HCV infection may ultimately decrease the number of patients needing liver transplantation. Suitable candidates with chronic HCV infection thus warrant treatment with pegylated interferon plus ribavirin combination therapy in the hope of decreasing disease progression. Recent studies, which require confirmation, suggest that nonresponders to standard antiviral therapy may benefit from maintenance therapy. The donor pool for patients with chronic hepatitis C and decompensated cirrhosis can be improved by using HCV-positive donors and by increasing utilization of newer surgical techniques, including adult-to-adult living-donor liver transplantation and split-liver transplantation.

Abstract
BACKGROUND Preliminary results of short-term famciclovir and lamivudine therapy in patients with hepatitis B virus (HBV) infection after liver transplantation revealed promising results. In a retrospective study the efficacy of long-term treatment with these substances was compared. METHODS A total of 53 HBV-infected adults (48 reinfections and 7 de novo infections) received antiviral treatment. A total of 32 of these patients were treated with famciclovir 3x500 mg, 20 of them were later switched to lamivudine. Fourteen patients received lamivudine, 150 mg/day orally, as first line therapy and 7 patients after failure of famciclovir-prophylaxis. Follow-up time was 8 to 62 months (mean 35 months). Response to therapy (HBV-DNA negative) was compared using Kaplan-Meier estimates. Potential influence factors (HBV-DNA and HBeAg pretransplant, HDV coinfection, pretreatment with famciclovir and immunosuppression) on treatment response were analyzed by log. Rank test (univariate); then a multivariate analysis (Cox multiple stepwise regression model) was applied. RESULTS A total of 19 and 76% of the patients treated with famciclovir and lamivudine resp. became HBV-DNA negative; 0 and 24% HBsAg negative. Lamivudine was also effective as second line therapy. In a multivariate analysis of all 73 treatment courses, lamivudine treatment and HDV-coinfection were significant factors for better treatment response; regarding only the lamivudine group, negative HBeAg pretransplant was significant. Viral breakthrough after prolonged treatment occurred in 55% (lamivudine) to 80% (famciclovir) of treatment courses but was only accompanied by mild hepatitis. CONCLUSIONS Lamivudine and famciclovir are potent drugs for the treatment of HBV-infection after liver transplantation. The antiviral capacity of lamivudine is superior even after pretreatment with famciclovir but after prolonged treatment viral breakthrough is often observed.

Abstract
Recurrent hepatitis B (HB) following orthotopic liver transplantation (OLT) for chronic disease is common. However, an unpredictable minority of patients follow a recurrence-free course. Clinical, virologic, and pathologic data from patients surviving longer than 60 days (n=24) with pathologically confirmed nonrecurrence of HB following OLT for chronic HB were reviewed to identify factors associated with nonrecurrence of HB. Nine of 24 patients had no histologic and immunohistologic evidence of recurrent HB. In addition to pre-OLT hepatitis B e antigen (HBeAg) negativity, coexisting delta and anti-HB therapy/prophylaxis, other acquired viral infections and their therapy, and severe acute rejection due to noncompliance were considered the possible protective factors against HB recurrence in these 9 patients. Histologic and, particularly immunopathologic, evaluation of liver biopsies must be utilized in definitively diagnosing recurrence of HB.

Abstract
Hepatitis B has been a major challenge within the field of transplantation over the past few decades. Due to aggressive recurrence post-transplant, patients with hepatitis B have been excluded from the benefits of both solid organ and bone marrow transplants. Progress has been made, however, through an improved understanding of the biology of hepatitis B and the development of new antiviral strategies that can reliably suppress the virus. Patients with hepatitis B are now candidates for transplantation in an increasing number of circumstances. Careful pre-transplant evaluation is mandatory, together with a tailored antiviral regimen depending on the replicative status of the virus and the organ being transplanted. Minimizing steroid dose following transplantation is an important part of the strategy to reduce the risk of viral reactivation. Lamivudine has been an important development and it has assumed an increasing role in the management of these patients. As additional antivirals are developed, increasingly effective drug combinations will prevent viral recurrence as well as the emergence of drug-resistant mutants, which plagues the use of single agents. It is a rapidly evolving field and there is every reason for continued optimism.

Abstract
Two human monoclonal antibodies (mAbs) against hepatitis B surface antigen (HBsAg) generated in the Trimera mouse system are described. Both mAbs 17.1.41 and 19.79.5 are of the IgG1 isotype and have high affinity constants for HBsAg binding in the range of 10(-10) mol/L. Monoclonal antibody 17.1.41 recognizes a conformational epitope on the a determinant of HBsAg whereas mAb 19.79.5 recognizes a linear one. The 2 mAbs bind to a panel of hepatitis B virus (HBV) subtypes with distinct patterns. The neutralizing activity of these antibodies was tested in 2 different animal model systems. Administration of each mAb to HBV-Trimera mice, a system that provides a mouse model for human hepatitis B infection, reduced the viral load and the percentage of HBV-DNA-positive mice in a dose-dependent manner. These 2 mAbs were more effective than a polyclonal antibody preparation (Hepatect; Biotest Pharma, Dreieich, Germany) in both inhibition of HBV liver infection and reduction of viral load. A single administration of a mixture of these mAbs into HBV chronic carrier chimpanzees resulted in immediate reduction in HBsAg levels followed by recurrence to initial levels within few days. Thus, these mAbs may be potential candidates for preventive therapy or in combination with other antiviral agents against HBV. Further studies in humans are needed to assess these mAbs in various clinical indications.

Abstract
Understanding and management of HBV and HCV infection in the OLT recipient has evolved rapidly in the last decade. The spontaneous risk for viral recurrence after transplantation is high, but has been decreased effectively in hepatitis B-positive recipients with the use of HBIG and lamivudine. HCV recurrence as defined by histologic injury is almost universal, although graft or patient outcomes for the first 8 years after OLT do not appear to be limited by HCV serostatus. However, effective prophylactic regimens that alter the natural history of HCV reinfection do not currently exist, and with longer follow-up into the second decade, the prevalence of HCV-related graft failure is likely to increase.

Abstract
Recurrent hepatitis B virus (HBV) infection of the liver graft is characterized by a severe outcome and high level of HBV replication. For many investigators, retransplantation appears contraindicated because of constant recurrence and a high mortality. We report our experience in this setting. Between January 1985 and December 1995, 10 patients who underwent retransplantation for HBV graft reinfection were studied. According to the antiviral treatment administered after HBV recurrence on the first liver graft and the protocol of antiviral prophylaxis after retransplantation, two groups were defined: group 1 underwent retransplantation before January 1992 (n = 5), and group 2 underwent retransplantation after January 1992 (n = 5). At the time of reinfection, serum HBV DNA was positive in all patients, hepatitis Be antigen (HBeAg) was positive in 6 patients. Antiviral therapy was administered to 7 patients (group 1, adenine arabinoside mono phosphate [ara-Amp; n = 3]; group 2, ara-Amp [n = 5], ganciclovir [n = 4]). After retransplantation, long-term antibody to HB surface antigen (anti-HBs) immunoglobulins were administered to achieve an anti-HBs titer greater than 100 IU/L in group 1 and to achieve an anti-HBs titer greater than 500 IU/L associated with prophylactic intravenous ganciclovir administration (5 mg/kg three times weekly) for 2 years in group 2. In group 1, all patients died, either perioperatively or secondary to HBV recurrence (1 year survival, 0%). In group 2, 1 patient died 50 months after retransplantation of HBV cirrhosis on the second graft, and 4 patients remained HBsAg negative at a mean of 41 months (range, 24 to 68 months) after retransplantation. The prognosis of retransplantation for HBV recurrence was dramatically improved by the administration of antiviral therapy before retransplantation and the maintenance of a high anti-HBs level combined with antiviral therapy after retransplantation.

Abstract
To assess whether Asian race is an independent variable affecting survival and hepatitis B virus (HBV) recurrence after liver transplantation, the results of 27 consecutive liver transplants performed between June 1994 and April 1997 for HBV cirrhosis were analysed. In the group of 13 Asians, 38% had associated hepatocellular carcinoma and 62% had positive hepatitis B virus early antigen (HBeAg) or elevated HBV-DNA before transplant. Prophylactic hepatitis B immunoglobulin (HBIG) was administered perioperatively and long term at 4-6 weekly interval. Four patients with elevated HBV-DNA received lamivudine before transplantation. The 3 year actuarial patient survival rate was 100% in both Asian and non-Asian patients. Twenty-six patients remained seronegative for hepatitis B virus surface antigen after transplantation. The incidence of post-transplant HBV recurrence was similar: 0% in Asians compared with 7% in non-Asians. There was no recurrence in the group of 12 patients who were HBV-DNA or HBeAg negative pretransplant.

Abstract
Hepatitis B virus (HBV) immune globulin (HBIg) administration will prevent HBV graft reinfection in HBV patients after orthotopic liver transplantation (OLT). However, the expenditure for such prophylaxis is extremely high ranging between $2,000 to $10,000 per month in various countries for an undefined period and presumably for life. As a consequence, there is a need for introduction of additional and less expensive modes of treatment. In a preliminary clinical trial a new HBIg preparation has been shown to induce longer lasting levels of circulating antibodies to hepatitis B surface antigen (anti-HBs) in patients after OLT compared with previous experience with conventional HBIg preparations. In the present study the pharmacokinetics of this new HBIg, OMRI-Hep-B, were studied and compared with a conventional, licensed preparation, Hepatect. Fifteen post-OLT patients (2-8 years post-OLT, 18-62 years of age, 6 men, 9 women) were treated intravenously with 49 doses of OMRI-Hep-B or Hepatect given at least once, alternately, at 10,000 to 14,000 units per injection ( approximately 130 IU/kg body weight). The new HBIg was well tolerated and no adverse effects were observed. Administration of OMRI-Hep-B was shown to induce high and long-lasting levels of circulating anti-HBs antibodies and greater areas under the curve (AUC) compared with the conventional preparation. Thus, anti-HBs half-life was 22 +/- 1.3 days for OMRI-Hep-B recipients and 13 +/- 1.3 days for Hepatect recipients (P <.001). Time to reach trough anti-HBs levels of 150 mIU/mL was significantly longer after administration of OMRI-Hep-B than after Hepatect (79 +/- 4.5 and 52 +/- 3.8 days, respectively; P <.001). In summary, the pharmacokinetic profile of the new HBIg, and in particular its prolonged elimination half-life, may reduce the cost of administration by approximately 30% and improve the quality of life of patients by extending the interval between repeated immune globulin injections.

Abstract
BACKGROUND There is concern that repeat orthotopic liver transplantation in patients with hepatitis C virus (HCV) infection may be associated with poor long-term survival. The specific aims of the current analysis were to determine (1) the prevalence of HCV infection in a large cohort of patients undergoing retransplantation, (2) define the impact of HCV infection on patient survival, and (3) determine the predictors of outcome of HCV-positive patients undergoing retransplantation for graft failure not caused by primary nonfunction. METHODS We analyzed the United Network of Organ Sharing (UNOS) registry data of 1539 adults undergoing orthotopic liver retransplantation between January 1990 and February 1996; 357 patients (23%) were HCV-positive. RESULTS The prevalence of HCV infection increased significantly from 6.5% in 1990 to 38.4% in 1995 (P<0.0001). Comparing the HCV-positive versus HCV-negative groups, there were no significant differences with regards to age, time to retransplantation, biochemical parameters immediately preceding retransplantation, UNOS registry status mix, or cause of graft failure (% with primary nonfunction). However, Kaplan-Meier analysis demonstrated significantly diminished survival in the HCV-positive group (P=0.0038, log-rank test; relative risk, 1.36; 95% confidence interval: 1.07-1.71). Multivariate logistic regression analysis of the subgroup of HCV-positive patients undergoing retransplantation for graft failure not caused by primary nonfunction identified preoperative serum bilirubin and serum creatinine as significant predictors of outcome. Seven of 207 (3.4%) patients undergoing retransplantation died of recurrent HCV in their second allografts. CONCLUSION The prevalence of HCV infection in patients undergoing retransplantation appears to have significantly increased since 1990. HCV infection is an independent risk factor for death after retransplantation. However, acceptable results are attainable in highly selected patients, i.e., those patients without severe hyperbilirubinemia and renal failure, and retransplantation remains the only viable option for patients whose allografts fail because of recurrent disease.
