Eur J Clin Invest 2021; 51:e13575. [PMID: 33866547 PMCID: PMC8365701 DOI: 10.1111/eci.13575] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/14/2021] [Revised: 04/04/2021] [Accepted: 04/13/2021] [Indexed: 12/22/2022]
Abstract
BACKGROUND Prophylaxis with hepatitis B immunoglobulin (HBIG) represents an efficient strategy for reducing the risk of hepatitis B virus (HBV) recurrence after liver transplantation (LT). Unfortunately, the long-term use of HBIG presents high costs. Therefore, the use of prophylaxis based only on nucleos(t)ide analogues (NUC) has been recently postulated. The present meta-analysis aimed to evaluate the impact of HBIG ± NUC vs HBIG alone or NUC alone in post-LT HBV recurrence prophylaxis. MATERIALS AND METHODS A systematic literature search was performed using PubMed and Cochrane databases. The primary outcome investigated was the HBV recurrence after LT. Three analyses were done comparing the effect of (a) HBIG + NUC vs HBIG alone; (b) HBIG+NUC vs NUC alone; and (c) HBIG alone vs NUC alone. Sub-analyses were also performed investigating the effect of low and high genetic barrierto-recurrence NUC. RESULTS Fifty-one studies were included. The summary OR (95%CI) showed a decreased risk with the combination of HBIG + NUC vs HBIG alone for HBV recurrence, being 0.36 (95% CI = 0.22-0.61; P < .001). HBIG + NUC combined treatment reduced HBV reappearance respect to NUC alone (OR = 0.22; 95% CI = 0.16-0.30; P < .0001). Similarly, HBIG alone was significantly better than NUC alone in preventing HBV recurrence (OR = 0.20; 95% CI = 0.09-0.44; P < .0001). CONCLUSIONS Prophylaxis with HBIG is relevant in preventing post-LT HBV recurrence. Its combination with NUC gives the best results in terms of protection. The present results should be considered in light of the fact that also old studies based on lamivudine use were included. Studies exploring in detail high genetic barrier-to-recurrence NUC and protocols with definite use of HBIG are needed.

Abstract
The combination of hepatitis B immunoglobulin (HBIG) and nucleos(t)ide analogues [NA(s)] is considered as the standard of care for prophylaxis against HBV recurrence after liver transplantation (LT), but the optimal protocol is controversial. We evaluated the efficacy of the newer NAs with high genetic barrier (hgbNA) [i.e. entecavir (ETV) or tenofovir (TDF)] with or without HBIG as prophylaxis against HBV recurrence after LT. In total, 519 HBV liver transplant recipients from 17 studies met the inclusion criteria and they were compared to those under lamivudine (LAM) and HBIG who had been selected in our previous review. Patients under HBIG and LAM developed HBV recurrence (115/1889 or 6.1%): (a) significantly more frequently compared to patients under HBIG and a hgbNA [1.0% (3/303), p < 0.001], and (b) numerically but not significantly more frequently compared to the patients who received a newer NA after discontinuation of HBIG [3.9% (4/102), p = 0.52]. The use of a hgbNA without any HBIG offered similar antiviral prophylaxis compared to HBIG and LAM combination, if the definition of HBV recurrence was based on HBV DNA detectability [0.9% vs. 3.8%, p = 0.11]. Our findings favor the use of HBIG and a hgbNA instead of HBIG and LAM combined prophylaxis against HBV recurrence after LT.

Abstract
AIM We investigated a protocol that lowered the necessary dose of anti-hepatitis B surface immunoglobulin (HBIg) with frequent monitoring of hepatitis B surface antigen (HBsAg) and antibody (HBsAb) levels in the early post-transplant period. METHODS Fifteen hepatitis B virus (HBV)-positive patients were studied. We administered a nucleoside analog from the preoperative period, high dose HBIg was used intraoperatively (200 IU/kg in the patients who weighed less than 50 kg, and 10 000 IU in those who weighed more than or equal to 50 kg) and was continued every day (5000-10 000 IU/day). Thereafter, HBIg was administered to keep the target trough titers. We evaluated the effectiveness and safety of this protocol for preventing HBV reactivation. RESULTS The average use of HBIg during the first three postoperative months (POM) was 27.9 ± 9.6 Kilo International Units. The average cost was $US11 800 in the first three postoperative months, compared with other previously reported protocols (about $20 000-40 000). HBV reactivation was detected in only one patient (6.7%) during the median follow up of 64 months (range: 12-86 months). CONCLUSIONS The present protocol for HBIg administration, which used frequent monitoring of HBsAg and HBsAb levels to determine the minimum required dose, was both safe and effective, and contributed to overall cost saving after liver transplantation.

Abstract
A combination of hepatitis B immunoglobulin (HBIG) and nucleos(t)ide analogues (NUCs) is currently recommended as prophylaxis against the recurrence of hepatitis B virus (HBV) after liver transplantation (LT), but the optimal protocol is a matter of controversy. The aim of this study was the identification of factors associated with post-LT HBV recurrence in patients receiving HBIG and NUCs. We searched MEDLINE and PubMed for studies in English about the effectiveness of HBIG and NUCs [lamivudine (LAM) and/or adefovir dipivoxil (ADV)] against post-LT HBV recurrence (January 1998 to June 2010). Forty-six studies, which included 2162 HBV LT recipients, met the selection criteria. Patients receiving HBIG and LAM experienced HBV recurrence more frequently than patients receiving HBIG and ADV with or without LAM [6.1% (115/1889) versus 2.0% (3/152), P = 0.024], although they also were more frequently treated with indefinite HBIG prophylaxis (90% versus 57%, P < 0.001). For patients receiving HBIG and LAM, a lower frequency of HBV recurrence was associated with a high HBIG dosage (≥10,000 IU/day) versus a low HBIG dosage (<10,000 IU/day) during the first week after LT [3.2% (14/440) versus 6.5% (80/1233), P = 0.016], but the HBIG protocol had no impact on HBV recurrence in patients receiving HBIG and ADV. In conclusion, in comparison with the combination of HBIG and LAM, the combination of HBIG and ADV is associated with a lower rate of HBV recurrence after LT. Patients receiving HBIG and LAM should be given a high dosage of HBIG during the first week after LT, but a lower dosage can be used safely in patients receiving HBIG and ADV. Further studies with newer and more potent anti-HBV agents are definitely required.

Abstract
BACKGROUND Recurrence of hepatitis B virus (HBV) infection in the liver graft is a grave complication following liver transplantation for HBV cirrhosis. Hepatitis B immunoglobulin (HBIg) seems effective in increasing survival after liver transplantation. HBIg and anti-viral drugs are given alone or in combination for its prevention. OBJECTIVES To assess the benefits and harms of different regimens for preventing HBV reactivation following liver transplantation. SEARCH STRATEGY We searched The Cochrane Hepato-Biliary Group Controlled Trials Register, The Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, MEDLINE, EMBASE, and Science Citation Index Expanded until February 2010. We attempted to identify further trials by reviewing the reference lists and contacting the principal authors of identified trials. SELECTION CRITERIA Randomised clinical trials addressing benefits and harms of lamivudine or adefovir dipivoxil alone or in combination with hepatitis B immunoglobulins (HBIg) for preventing recurrent HBV infection in patients who are liver transplanted due to HBV infection with or without hepatocellular carcinoma. DATA COLLECTION AND ANALYSIS Two authors independently assessed the trials for risk of bias and extracted data. We contacted study authors whenever information was lacking. We collected information on adverse events. The primary outcomes were all-cause mortality and reappearance of hepatitis B surface antigen in serum after liver transplantation. Relative risks were calculated from individual trials. MAIN RESULTS Four trials, recruiting 136 participants, were included. Two trials compared lamivudine alone versus HBIg alone. Randomisation was performed one week after transplantation in one of the trials and after six months after transplantation in another; from transplantation until randomisation, HBIg alone was given to all patients in the two trials. A third trial compared combination treatment with lamivudine and HBIg versus lamivudine alone after one month of combination treatment, and a fourth trial compared the combination of lamivudine and HBIg versus a combination of lamivudine and adefovir dipivoxil after at least 12-month of lamivudine and HBIg combination treatment. Statistically significant differences were not detected in any of the comparisons and outcomes. All trials were open-labelled, and none of the trials were adequately powered to show a difference in HBV recurrence. No meta-analyses were performed since the identified trials assessed different comparisons. AUTHORS' CONCLUSIONS This review could not derive clear evidence from randomised clinical trials for the treatment of patients with chronic HBV following liver transplantation for preventing recurrence of HBV infection. Large randomised clinical trials comparing long-term combination treatment to each of the monotherapy alone, including the newer antiviral drugs, are needed.

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
This paper reviews a meeting at which basic pathophysiology of infections, mechanisms of action of hyperimmune products and pharmacokinetic and pharmacodynamic parameters, as well as currently available hyperimmunes and their potential new targets and uses, were discussed. A hyperimmune product was defined as either a monoclonal antibody or a polyclonal preparation enriched with antibody directed against one or more particular targets. A number of issues were emphasised, including: resistant bacterial pathogens, such as Staphylococcus aureus and Streptococcus pyogenes; the role of hyperimmune intravenous globulins in the prevention of sepsis in low birthweight infants; hepatitis B virus infection associated with liver transplantation; combination therapy; the potential role of hyperimmunes in the prevention and treatment of hepatitis C virus; and the use of immunoglobulins for the prophylaxis of Epstein-Barr virus-related lymphoproliferative disease. Routes of administration were also discussed. It was concluded that the development of hyperimmunes faces numerous obstacles. It was agreed that the use of hyperimmunes in clinical trials must be standardised; clinical trials must be large enough to have sufficient power to demonstrate efficacy with clear-cut end-points, and means need to be developed, in conjunction with regulatory agencies, for the feasible evaluation of combination products. However, progress in all these aspects will provide a wide range of hyperimmunes for future use.

Abstract
The progress in treatment against hepatitis B virus (HBV) has substantially improved the outcome of all HBV-infected patients. We systematically reviewed the existing data in the management of HBV transplant patients in order to assess the optimal regimen in the pretransplant setting, for post-transplant prophylaxis and for therapy of HBV recurrent infection. All data suggest that an effective pretransplant anti-HBV therapy prevents post-transplant HBV recurrence. Pretransplant therapy has been based on lamivudine with addition of adefovir upon lamivudine resistance, but the use of newer, potent high-genetic barrier agents is expected to improve long-term efficacy. Moreover, it may lead to improvement of liver function, which sometimes removes the need for transplantation, although more objective criteria for removal from waiting lists are required. After liver transplantation, the combination of HBV immunoglobulin and one nucleos(t)ide analogue, mostly lamivudine, is currently the best approach, almost eliminating the probability of HBV recurrence. Treatment of post-transplant HBV recurrence has been mainly studied with lamivudine, but it will be most effective with entecavir and tenofovir, which have a low risk of resistance. In conclusion, the newer anti-HBV agents improve the treatment of HBV both pretransplant and post-transplant. HBV immunoglobulin is still used in combination with an anti-HBV agent for post-transplant prophylaxis. Monoprophylaxis with one of the new anti-HBV agents might be possible, particularly in patients preselected as having a low risk of HBV recurrence, but further data are needed and strategies to ensure compliance must be used.

Abstract
UNLABELLED Prior to effective prophylaxis, liver transplantation for hepatitis B virus (HBV)-related disease was frequently complicated by recurrence, which could be severe and rapidly progressive. Combination hepatitis B immunoglobulin (HBIG) and lamivudine prophylaxis reduces this rate of recurrence to <5% at 5 years; however, HBIG administration is costly and inconvenient. We conducted a multicenter randomized study of adefovir dipivoxil substitution for low-dose intramuscular (IM) HBIG in patients without HBV recurrence at least 12 months posttransplantation for HBV-related disease. Thirty-four patients were randomized, 16 to adefovir (1 patient withdrew consent at 3 months and is not considered in the results) and 18 to continue HBIG. All continued lamivudine. Groups were well matched by age, sex, and time since transplantation (median, 4.5 years), and background virological risk for HBV recurrence (30% of patients in the adefovir group, 24% in the HBIG group having detectable HBV DNA at transplantation). All patients were alive at study completion without recurrence. One patient in the adefovir group became hepatitis B surface antigen-positive at 5 months but was persistently HBV DNA undetectable via polymerase chain reaction (sensitivity 14 IU/mL) over the following 20 months. Median creatinine was not significantly changed over the course of the study in either group. One patient in the adefovir group with a background of diabetic and hypertensive nephropathy (baseline creatinine 150 micromol/L) developed increased creatinine leading to dose reduction and ultimately cessation of adefovir at 15 months. Yearly cost of combination adefovir/lamivudine prophylaxis was $8,290 versus $13,718 IM HBIG/lamivudine. CONCLUSION Compared with combination HBIG plus lamivudine prophylaxis, combination adefovir plus lamivudine provides equivalent protection against recurrent HBV infection but with better tolerability and less cost.

Abstract
BACKGROUND & AIMS HBV recurrence increases morbidity and mortality in HBsAg+ patients undergoing liver transplantation. We aimed to estimate the relative efficacy of combined therapy with hepatitis B immunoglobulin (HBIG) and lamivudine (LAM) versus HBIG monotherapy for preventing HBV-related morbidity and mortality in this setting. METHODS We performed a meta-analysis of clinical trials that met the prespecified criteria and provided data for risk estimation of HBV recurrence in HBsAg+ liver transplant patients receiving HBIG and LAM versus HBIG alone. Databases searched until May 2007 included MEDLINE (Ovid), PubMed, Embase, Toxnet, Scopus, and Web of Science. Literature search and data extraction were conducted independently by 2 study investigators; then 2 other investigators reviewed and screened eligible studies. Odds ratios (ORs) for the risk reduction with HBIG and LAM versus HBIG alone were calculated by using a random-effects model. RESULTS Two prospective and 4 retrospective studies were included in the meta-analysis. The OR showing risk reduction in HBV recurrence with HBIG and LAM (n = 193) versus HBIG alone (n = 124) was 0.08 (95% confidence interval [CI], 0.03-0.21). HBV-related death and all-cause mortality could only be assessed in 3 studies each. The ORs showing HBV-related death and all-cause mortality reduction with HBIG and LAM versus HBIG alone were 0.08 (95% CI, 0.02-0.33) and 0.02 (95% CI, 0.06-0.82), respectively. CONCLUSIONS Although this meta-analysis was limited by small studies and varying levels of immunosuppression, it is apparent that adding LAM to HBIG improved HBV-related morbidity and mortality in HBsAg+ recipients of liver transplants.

Abstract
BACKGROUND Treatment of post-transplantation recurrence of hepatitis B virus (HBV) infection despite prophylaxis with hepatitis B immunoglobulin (HBIG) and lamivudine combination therapy is not easy. Because HBV reinfection has a severe course and could result in graft failure in liver transplant recipients, prompt medication is essential. Herein is reported the authors' experience with adefovir dipivoxil (AD) therapy in 11 liver transplant recipients who had HBV reinfection despite the administration of lamivudine and HBIG. METHOD Two-hundred and nine patients underwent liver transplantation (100 deceased donor liver transplantations [DDLT], 109 living donor liver transplantation [LDLT]) due to chronic hepatitis B infection between April 1997 and May 2005 in Ege University Medical School, Liver Transplantation Unit. Patients had prophylaxis with lamivudine and low-dose HBIG combination after liver transplantation. Treatment of recurrence consisted of AD 10 mg once a day and lamivudine 300 mg/daily and HBIG was discontinued in those patients. RESULTS In total there were 11 HBV recurrences: five occurred in DDLT recipients and six in LDLT recipients, at a median follow up of 18 months (range, 6-48 months). In one of 11 patients, pretransplant HBV-DNA and HBeAg were positive. Three patients had a severe course and one patient had fibrosing cholestatic hepatitis. After AD treatment, HBV-DNA level decreased in all patients and became negative in seven patients. Two patients died due to hepatocellular carcinoma recurrence after 12 and 14 months of follow up. Serum creatinine level increased mildly in one patient and no other side-effect was observed, and all patients continued therapy. CONCLUSION Adefovir dipivoxil is a safe, effective treatment option for post-transplant HBV recurrence even among patients with fibrosing cholestatic hepatitis caused by lamivudine-resistant HBV.

Abstract
BACKGROUND AND AIM Living donor liver transplantation (LDLT) has particular advantages for Turkey where hepatitis B virus (HBV) infection is the most common cause of cirrhosis, both because LDLT circumvents the difficulties encountered in the emerging world in providing deceased donor organs, and because it allows preemptive antiviral therapy. The aim of this study was to review one institution's experience with LDLT in patients with chronic HBV infection. METHODS A total of 109 patients with chronic HBV infection underwent LDLT between September 1999 and June 2005, of whom 40 were coinfected with hepatitis D virus and 23 had hepatocellular carcinoma. Antiviral prophylaxis was attempted in all, beginning prior to transplantation with lamivudine or adefovir, and continuing after transplantation with low dose intramuscular hyperimmune B immunoglobulin (HBIg) plus lamivudine or adefovir. RESULTS In a median follow up of 20 months (range 1-66 months), there was no donor mortality. One-year recipient survival was 90%, and in total 16 recipients died. None of the deaths was related to HBV. Recurrence of HBV infection was detected by reappearance of serum hepatitis B surface antigen in six patients (5.5%) at 5, 8, 12, 17, 34 and 46 months after transplantation, respectively. There was no influence of donor hepatitis B core antibody status on the likelihood of recurrence of HBV in the allograft. CONCLUSION The results indicate that LDLT with antiviral treatment and low dose HBIg provides excellent results for donors and recipients.

Abstract
Liver transplantation for hepatitis B virus (HBV)-related liver disease has changed from a contraindication to outcomes comparable with non-HBV-related liver transplantations during the last two decades. Mainly the implementation of immunoprophylaxis with hepatitis B immunoglobulin (HBIG) and the use of nucleoside analogs such as lamivudine and adefovir account for this dramatic change. The standard of care in most centers today consists of lamivudine treatment in replicating hepatitis B pre-orthotopic liver transplantation (OLT) and a combination regimen of lamivudine and HBIG post-OLT. With adefovir, a potent antiviral drug became available in recent years that allows for the treatment of patients with lamivudine-resistant tyrosine-methionine-aspartate-aspartate (YMDD)-mutant HBV. In the transplantation setting, first studies indicate that a triple prophylactic therapy consisting of lamivudine, adefovir, and HBIG will become the standard of care for YMDD-mutant-related hepatitis B. With new drugs emerging for the treatment of chronic HBV, there is optimism for new options also in the transplant setting.

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
BACKGROUND AND AIMS High-dose intravenous hepatitis B immunoglobulin (HBIG) may prevent recurrent hepatitis B virus (HBV) infection, but the cost has limited its widespread use in countries with endemic HBV infection. We report on long-term safety and efficacy of an alternative strategy of very low doses (400-800 IU/month) of intramuscular (IM) HBIG plus lamivudine. METHODS Australian and New Zealand patients who received low-dose HBIG plus lamivudine following liver transplantation for HBV-related end-stage liver disease were studied. Prior to transplantation, patients with detectable serum HBV DNA received lamivudine 100 mg daily. Posttransplantation, all patients received lamivudine 100 mg daily plus IM HBIG 400 or 800 IU daily for 1 week then monthly thereafter. Serum HBV DNA levels were measured prior to lamivudine, at transplantation, and at 12 months posttransplantation. Serum titers of antibody to HBV surface antigen were measured at 1, 3, and 12 months posttransplantation. RESULTS Between February 1996 and October 2004, 147 patients received low-dose HBIG plus lamivudine. Thirty-one percent were hepatitis B e antigen positive, and 85% were HBV DNA+ prior to transplantation. The median duration of pretransplantation lamivudine was 92 days (range, 1-1775). Median follow-up posttransplantation was 1860 days. Kaplan-Meier patient survival was 92% at 1 year and 88% at 5 years. The actuarial risk of HBV recurrence was 1% at 1 year and 4% at 5 years. Baseline HBV DNA titer was associated with HBV recurrence. CONCLUSION Low-dose IM HBIG plus lamivudine provides safe and effective long-term prophylaxis against recurrent HBV at <10% the cost of the high-dose regimen.

Abstract
1. The use of low-dose immunosuppressive therapy along with pre- and posttransplantation nucleos(t)ide therapy and posttransplantation hepatitis B immunoglobulin (HBIG) has yielded marked improvements in survival. 2. Lamivudine (Epivir-HBV), adefovir (Hepsera), entecavir (Baraclude), tenofovir (Viread), emtricitabine (Emtriva), and the combination drugs tenofovir + emtricitabine (Truvada) and abacavir + lamivudine (Epzicom) are effective nucleos(t)ide antiviral agents that, in some cases, may help reverse liver disease sufficiently to avoid transplant. 3. In posttransplantation patients, virus suppression with some combination of HBIG and the nucleos(t)ide agents may prevent graft loss and death or the need for a second transplant. 4. In both the pre- and posttransplantation setting, the goal of hepatitis B virus management is complete virus suppression. 5. The use of low-dose intramuscular HBIG is evolving, with studies showing that dosing and cost can be reduced by 50-300% with a customized approach. 6. Elimination of HBIG from the treatment paradigm is currently under evaluation and may be possible with the use of newer medications that have no or low resistance rates. 7. Although there is growing evidence that some types of combination therapy may decrease the chance that drug resistance will develop and increase the likelihood of long-term success in preventing graft loss and death, additional research will be required to determine which combinations will work well in the long term, and which will not.

Abstract
BACKGROUND Hepatitis B virus (HBV) patients with cirrhosis are at risk for developing costly, morbid, or mortal events, and therefore need highly effective therapies. Lamivudine is effective but is limited by viral resistance. In contrast, adefovir and entecavir have lower viral resistance, but are more expensive. The most cost-effective approach is uncertain. METHODS We evaluated the cost-effectiveness of six strategies in HBV cirrhosis: (1) No HBV treatment ("do nothing"), (2) lamivudine monotherapy, (3) adefovir monotherapy, (4) lamivudine with crossover to adefovir on resistance ("adefovir salvage"), (5) entecavir monotherapy, or (6) lamivudine with crossover to entecavir on resistance ("entecavir salvage"). The primary outcome was the incremental cost per quality-adjusted life-year (QALY) gained. RESULTS The "do nothing" strategy was least effective yet least expensive. Compared with "do nothing," using adefovir cost an incremental US dollars 19,731. Entecavir was more effective yet more expensive than adefovir, and cost an incremental US dollars 25,626 per QALY gained versus adefovir. Selecting between entecavir versus adefovir was highly dependent on the third-party payer's "willingess-to-pay" (e.g., 45% and 60% of patients fall within budget if willing-to-pay US dollars 10K and US dollars 50K per QALY gained for entecavir, respectively). Both lamivudine monotherapy and the "salvage" strategies were not cost-effective. However, between the two salvage strategies, "adefovir salvage" was more effective and less expensive than "entecavir salvage." CONCLUSION Both entecavir and adefovir are cost-effective in patients with HBV cirrhosis. Choosing between adefovir and entecavir is highly dependent on available budgets. In patients with HBV cirrhosis with previous lamivudine resistance, "adefovir salvage" appears more effective and less expensive than "entecavir salvage."

Abstract
The reults of orthotopic liver transplantation (OLT) for hepatitis B virus (HBV) related liver disease are significantly influenced by the HBV recurrence rate. Complete eradication of hepatitis B is rarely possible after liver transplantation and hepatic and extrahepatic reservoirs are a continuous latent source of HBV recurrence. Therefore an adequate prophylaxis is mandatory. By introduction of long term passive immunoprophylaxis the recurrence rate could be markedly reduced and survival rates significantly improved. Due to the approval of antiviral drugs, especially lamivudine as the first approved antiviral agent against HBV, new prophylactic options, including combination prophylaxis, have been introduced. This modern antiviral managemant improved the outcome of hepatitis B patients after liver transplantation. The Results after OLT are nowadays reported to be as good or in a recent UNOS database report even better than in non-HBV patients. The type of recommended prophylaxis has undergone modifications within the last years and is still subject to changes due to the ongoing development of antiviral agents. In addition, due to high costs of hepatitis immunoglobulin alternatives such as prophylaxis with nucleos(t)ide analogues or vaccination are increasingly investigated. In the following, current strategies of reinfection prophylaxis and future perspectives are reviewed.

Abstract
The Hepatitis B virus (HBV) is a DNA virus that can cause both acute and chronic liver disease in humans. Approximately 350–400 million people are affected worldwide and up to one million deaths occur annually from cirrhosis and hepatocellular carcinoma. When cirrhosis and liver failure develop, the definitive treatment of choice remains orthotopic liver transplantation (OLT). In the past, an unacceptable HBV recurrence rate with a high rate of graft loss was noted. The use of Hepatitis B immunoglobulin (HBIG) has resulted in improved patient and graft survival rates. The addition of the nucleoside analog Lamivudine (LAM) to HBIG has improved these survival curves to an even greater degree. Prolonged use of LAM will almost invariably lead to the development of viral mutations resistant to the drug. There are now several other nucleoside and nucleotide analogs (Adefovir, Entecavir, Tenofovir, and Truvada) available for the clinician to utilize against these resistant strains. It should be possible to prevent recurrence in most, if not all, post-transplant patients and also to significantly reduce viral loads with normalization of transaminases in those who have developed recurrent infection. The antiviral regimen should be robust and minimize the risk of breakthrough mutations. A prudent approach may be the implication of combination antiviral therapy. This review summarizes the efficacy of previous regimens utilized to prevent and treat recurrent HBV following OLT. Particular attention will be paid to the newer nucleoside and nucleotide analogs and the direction for future strategies to treat HBV in the post transplant setting.

Abstract
The combination of lamivudine and hepatitis B immunoglobulin (HBIG) reduces the risk of hepatitis B virus (HBV) recurrence after liver transplantation (LT). However, the efficacy of this strategy and the need for combined therapy with adefovir dipivoxil (ADV) in patients who select lamivudine-resistant strains (YMDD) before surgery is still unknown. Twenty-two patients treated with lamivudine (LAM) who underwent LT after YMDD-mutant selection were studied. In 13 patients, YMDD mutants were associated with an HBV DNA breakthrough greater than 5 log10 (group A: phenotypic resistance), and 11 were treated with ADV to decrease viral load before LT. In the remaining 9 patients who did not experience the viral breakthrough, YMDD mutants were detected only retrospectively in sera stored at the time of LT (group B: genotypic resistance). During 35 months of post-LT follow-up, none of the 11 patients of group A treated with ADV before and after surgery (in addition to HBIG and LAM) had HBV recurrence, and neither did any of the 7 subjects of group B treated with LAM before and after transplantation (in addition to HBIG). HBV recurred in 2 patients of group A (untreated with ADV before surgery and transplanted with an HBV DNA exceeding 5 log10) and in 2 subjects of group B (who spontaneously stopped HBIG after surgery). In carriers of YMDD mutants, the risk of post-LT HBV recurrence is low, provided that preemptive and prophylactic ADV (in addition to LAM and HBIG) treatment is used in highly viremic patients and prophylactic LAM (or ADV) and HBIG therapy is continued in low viremic patients.

Abstract
Hepatitis B virus (HBV) recurrence after liver transplantation is significantly reduced by prophylaxis with hepatitis B immune globulins (HBIG) or antiviral drugs in nonreplicating patients and by the combination of both drugs in replicating patients. However, the load of HBV DNA, which defines replicating status in patients undergoing liver transplantation, remains unclear. This study analyzes the correlation between the viral load, tested with a single amplified assay, at the time of liver transplantation, and the risk of hepatitis B recurrence in 177 HBV carriers who underwent transplantation in a single center from 1990 to 2002. Overall, HBV relapsed after surgery in 15 patients (8.5%) with a 5- and 8-year actuarial rate of recurrence of 8% and 21%, respectively. After liver transplantation hepatitis B recurred in 9% of 98 selected subjects treated only with immune globulins and in 8% of 79 viremic patients who received immune globulins and lamivudine (P = NS). A linear correlation was observed between recurrence and viral load at the time of surgery. In transplant patients with HBV DNA higher than 100,000 copies/mL, 200-99,999 copies/mL, and DNA undetectable by amplified assay, hepatitis B recurred in 50%, 7.5%, and 0% of patients, respectively. Overall, a viral load higher than 100,000 copies/mL at the time of liver transplantation was significantly associated with hepatitis B recurrence (P = .0003). In conclusion, spontaneous or antiviral-induced HBV DNA viral load at the time of surgery classifies the risk of HBV recurrence after liver transplantation and indicates the best prophylaxis strategy.

Abstract
The outcome of OLT for HBV-related liver disease is dependent on the prevention of allograft re-infection. Over the past decade, major advances have been made in the management of HBV transplant candidates. The advent of long-term hepatitis B immune globulin (HBIG) administration as a prophylaxis against HBV recurrence, and the introduction of new antiviral agents against HBV infection, such as lamivudine (LAM), were a major breakthrough in the management of these patients. Results of OLT for HBV infection are similar to those achieved with other indications. Pre-OLT antiviral treatment such as LAM can suppress HBV replication before OLT and thus decrease the risk of re-infection of the graft. Combination prophylaxis with LAM and HBIG after transplantation highly effectively reduces the rate of HBV re-infection, even in HBV replicative cirrhotic patients. The optimal HBIG protocol in the LAM era is yet to be defined: dosing of HBIG, routes of administration, and possibility of stopping HBIG. Several antiviral drugs have been developed for the management of HBV infection on the graft, so outcome is currently good.

Abstract
In the absence of preventative therapy, reinfection of allografts with hepatitis B virus (HBV) after orthotopic liver transplantation (OLT) resulted in dismal allograft and patient survival. Major advances in the management of HBV-infected recipients of OLT during the past 15 years have steadily reduced the rate of reinfection, resulting in improved outcomes. Initially, long-term use of hepatitis B immune globulin (HBIG) as a source of anti-HBs antibodies was effective in preventing or delaying reinfection. Lamivudine monotherapy made it possible to suppress HBV replication prior to OLT, markedly decreasing the risk of reinfection. Although lamivudine monotherapy used before and after OLT could prevent reinfection, its effectiveness was limited by progressive development of lamivudine-resistant mutant infections. Combination therapy with HBIG and lamivudine after OLT reduced both HBV recurrence and the risk of lamivudine resistance even in patients with active HBV replication. Introduction of adefovir provided a safe, alternative oral antiviral able to treat effectively lamivudine-resistant mutants HBV. Available strategies to prevent reinfection have resulted in OLT outcomes for HBV-infected patients comparable to those for patients transplanted for non-HBV indications. In the future, combination therapies of HBIG and both nucleoside and/or nucleotide agents will undoubtedly be optimized. Development of new drugs to treat HBV will increase opportunities to combine agents to enhance safety, efficacy and prevent emergence of HBV escape mutants. New vaccines and adjuvants may make it possible to generate anti-HBs in immunosuppressed patients, eliminating the need for HBIG.

Abstract
Redistribution of virions from extrahepatic reservoirs with resultant reinfection of the graft is a serious complication after liver transplantation for hepatitis B-related liver disease. Prophylaxis of hepatitis B virus recurrence is a major issue in these patients. With the introduction of passive immunoprophylaxis and the development of antiviral drugs, liver transplantation has evolved as an established therapy of hepatitis B-induced end-stage liver failure. However, even under indefinite monoprophylaxis, a significant percentage of patients develop reinfection due to a high mutation rate of the hepatitis B virus. Progress, especially in the field of antiviral therapy, has opened new strategies, including combination prophylaxis and therapy, which further improve outcome. On the other hand, the broad use of antiviral drugs brings about new problems such as resistance formation prior to liver transplantation. In addition, due to the high costs of hepatitis B immunoglobulin alternatives such as prophylaxis with nucleoside analogs or vaccination are increasingly being investigated.

Abstract
1. Long-term prophylaxis with hepatitis B immune globulin (HBIG) significantly reduces the risk for hepatitis B virus (HBV) recurrence and increases survival. Patients with HBV cirrhosis and / or positive HBV DNA at the time of transplantation have a high risk for recurrence despite HBIG prophylaxis. 2. Pre-orthotopic liver transplantation (OLT) antiviral treatment using lamivudine (LAM) can suppress HBV replication before transplantation and may induce clinical improvement in a subset of patients. Adefovir dipivoxil (ADV) may serve as "rescue" therapy for patients with LAM resistance; its place as first-line therapy requires further evaluation. 3. Combination prophylaxis with LAM and HBIG prevents HBV recurrence in 90% to 100% of patients who undergo transplantation for hepatitis B. The optimal HBIG protocol in the "nucleoside-nucleotide analog era" remains to be determined. The place of ADV or LAM as first-line posttransplant antiviral therapy in combination with HBIG requires further studies. 4. Future research should test new protocols using lower HBIG doses given intravenously (IV) or intramuscularly (IM) alone or in combination with antiviral agents and identify patients in whom HBIG prophylaxis can be stopped safely or replaced by antiviral agents or vaccination.

Abstract
Post-transplant prevention of hepatitis B virus (HBV) infection is based on treatment with lamivudine and/or hepatitis B immune globulin (HBIG). However, optimum doses and duration for these drugs are not yet clear. We tested high doses of lamivudine (300 mg/day) in combination with low doses of HBIG (200–400 IU/2–4 weeks). Eighty patients who had post-transplant prophylaxis of lamivudine and HBIG were included in the study. Of those, 20 had hepatitis D virus co-infection and eight were HBV DNA-positive at the time of transplantation. Ten HBV DNA-positive patients were treated with lamivudine (150 mg/day) before transplantation; all were HBV DNA-negative after lamivudine treatment. All patients in the anhepatic phase were given 4000 IU of HBIG. Following this, 400 or 800 IU HBIG was administered intramuscularly daily for 5–10 days post-transplantation and 2–4 times weekly thereafter, according to serum titre of antibodies to hepatitis B surface antigen (anti-HBs). Lamivudine was maintained or initiated at the time of transplantation and was continued indefinitely. Median follow-up was 21 months (range 3–73 months). Recurrence of hepatitis B surface antigen (HBsAg)-positivity occurred in only three out of 78 (4%) patients; two of these three were HBV DNA-positive. Median anti-HBs titre at the final follow-up was 68 IU. Patient and graft survival was 85% at 1 year. In conclusion, a combination of lamivudine 300 mg/day and low-dose HBIG prevents post-transplantation recurrence of hepatitis B, even in the presence of viral replication in the pre-transplant period.

Abstract
BACKGROUND Cost of long-term prophylaxis with high-dose human hepatitis B immune globulin (HBIg) after liver transplantation is extremely high. The aim of the present study was to assess consumption rates of high (5,000 IU) and low (2,000 IU) doses of HBIg given intravenously "on demand", and determine their cost-effectiveness compared with conventional fixed monthly schedules. METHODS The study included 11 male patients (mean age 53 years) who received transplants for hepatitis B virus (HBV)-related cirrhosis 29 to 96 months earlier, all receiving lamivudine (100 mg/day) prophylaxis. Each patient received three consecutive intravenous infusions of 5,000 IU HBIg, followed by three 2,000 IU infusions. HBIg consumption was assessed by serial measurement of serum hepatitis B surface antibody (HBsAb) titer at 2-week intervals. HBIg was readministered only when HBsAb titers dropped below 70 IU/L (i.e., "on demand"). RESULTS Mean HBsAb peak titers after high and low HBIg doses were 1,641 +/- 385 and 848 +/- 216 IU/L, respectively (P <0.0001). Mean time to reach an HBsAb titer less than 70 IU/L was 79.5 +/- 38.2 days versus 61.6 +/- 32.1 days, respectively (P =NS). Interindividual variation coefficients were 23 +/- 18% and 32 +/- 26% (5,000 IU and 2,000 IU, respectively). Using the on demand approach, maintenance of a protective anti-HBs titer required an average number of 4.0 (5,000 IU) and 5.6 (2,000 IU) HBIg administrations per year, respectively (P =NS). CONCLUSIONS Individual HBIg consumption profiles are highly variable. A low-dose (2,000 IU) on demand HBIg administration schedule is highly cost-effective and provides more than 50% savings compared with conventional high-dose monthly schedules.

Abstract
For the prevention of recurrent hepatitis B virus (HBV) infection after liver transplantation (LT), the efficacy of hepatitis B immunoglobulin (HBIg) has been largely demonstrated. The aim of this pilot study was to determine if the addition of lamivudine to HBIg in the prevention of HBV recurrence after LT could be more effective. Sixty HBsAg-positive/HBV DNA-negative patients underwent LT from October 1990 to December 2001. All 60 patients received intravenous HBIg to maintain serum anti-HB levels above 500 IU/L, indefinitely. Since 1997, 17 patients have received combined oral lamivudine (150 mg/day) and HBIg, and were compared with the historical cohort of 43 patients. In the historical control group, the recurrence rate was 10/43 (23%) after a 98-month median follow-up. Five patients died from HBV-related liver disease. After a 30-month median follow-up, none of the 17 patients in the combined prophylaxis group experienced HBV recurrence, and HBV DNA was undetectable by PCR in at least three serum samples per patient. HBV recurrence was significantly lower when compared with the historical control group (10/43 vs. 0/17, p < 0.01). Our results suggest that combined lamivudine and HBIg can avoid the recurrence of HBV infection in patients who are HBsAg-positive/HBV DNA negative before LT.

Abstract
Antiviral prophylaxis with lamivudine appears to reduce hepatitis B virus (HBV) infection after liver transplantation, although recurrence of infection occurs in at least 20% of the patients because of the development of drug resistance. Treatment for HBV reinfection with lamivudine pretransplantation and posttransplantation together with hepatitis B immunoglobulin could abolish recurrence of HBV infections following liver transplantation. We report the experience at our center in which lamivudine has been used in combination with low doses of immunoglobulin. Lamivudine (100 mg/d) was administered to liver transplant candidates for at least 4 weeks before transplantation and was continued posttransplantation indefinitely. Immunoglobulin was administered intramuscularly (10,000 IU at time of liver transplantation; 1,000 IU for 1 week; 1,000 IU weekly the first month; and 1,000 IU monthly thereafter). Lamivudine and low-dose immunoglobulin administration prevents posttransplantation recurrence of hepatitis B with 100% efficiency; it is well tolerated and is less cost-effective than high-dose immunoglobulin regimens.

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
INTRODUCTION Prophylaxis using high-dose intravenous anti-HBV immune globulin (HBIG) is effective to prevent reinfection due to hepatitis B virus (HBV) after orthotopic liver transplantation (OLT). However, this treatment is expensive and intravenous administration is difficult during outpatient care. Our aim was to assess the effectiveness of low-dose intramuscular HBIG to prevent HBV reinfection after OLT. PATIENTS Six patients (all men, mean age 41 years, negative HBV DNA without hepatotropic virus coinfection) were transplanted in our institution due to HBV cirrhosis and included in a prospective noncomparative study. Intramuscular HBIG (2000 IU) was administered during the anhepatic phase of OLT, followed by daily 2000 IU doses for 7 days and then monthly. HBV antibody titers were measured every month. Reinfection was defined as the recurrence of surface HBV antigen in serum after transplantation. RESULTS After 1 year follow-up, none of the six patients had detectable HBV surface antigen and the liver biopsies were normal in all cases. Using 2000 IU, anti-HBs levels were: 880+/-356 IU/L at 1 month, 191+/-123 at 6 months, and 225+/-49 after 1 year. In all cases anti-HBs titers were above 100 IU/L during the follow-up. CONCLUSIONS Monthly administration of low-dose (2000 IU) intramuscular HBIG effectively prevents recurrence of HBV infection as well as attains a protective level of anti-HBs antibodies (over 100 IU/L) for at least the first year after transplantation.

Abstract
The management of the immunosuppression treatment must take account its consequences on viral replication. Such treatment operates on the emerging balance between the recurrence of the virus on the graft and the immune response of the host. Randomized and prospective trials are currently ongoing with the purpose of determining the opportunity and relevance of each immunosuppressive agent in the treatment. In HBV patients, good control of HBV reinfection by prophylactic strategies using HBIG, lamivudine, or both have decreased the impact of immunosuppression on HBV recurrence. In contrast, HCV recurrence is now a major problem. The mechanisms of viral recurrence need to be deepened thus requiring new studies. The absence of in vitro and in vivo systems to study HCV reinfection is a lack in the comprehension of the relation between HCV and immunosuppression. It will allow adapting the effectiveness of the immunosuppression treatment. The treatment's primary target is to avoid graft rejection, and its secondary objective is to limit the risk of viral recurrence.

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
BACKGROUND Hepatitis B (HBV)-infected patients receive an anti-HBs immunoprophylaxis [hepatitis B immunoglobulin (HBIG) titre of more than 100 IU/L] in combination with lamivudine to prevent reinfection after orthotopic liver transplantation (OLT). In comparison with intramuscular (i.m.) HBIG, costs for intravenous (i.v.) HBIG are found to be extremely high. We therefore studied patients' outcome (i) after a switch from i.v. to i.m. HBIG and (ii) the outcome after the patients were initially treated with i.m. HBIG after discharge from the hospital. METHODS (i) Six outpatients were switched from 2000 IU i.v. HBIG (Hepatect) administered every 2 wk to 2000 IU i.m. HBIG (Hepatitis-B-Immunoglobulin Behring) given once a month. (ii) Six other outpatients were directly treated with i.m. HBIG every 4 wk after OLT. All patients also received 100 mg lamivudine/d. RESULTS Patients switched from i.v. to i.m. HBIG had stable anti-HBs titres (i.v. HBIG: 180 +/- 37 IU/L vs. i.m. HBIG: 173 +/- 23 IU/L). Patients directly treated with i.m. HBIG also had sufficient anti-HBs titres (176 +/- 31 IU/L). Intramuscular application of HBIG was well tolerated by all patients and no side-effects were observed in patients receiving i.m. HBIG. In comparison with the protocol using i.v. HBIG, the costs of i.m. treatment were 60% lower. CONCLUSION Long-term administration of i.m. HBIG saves up to 60% of the usual costs for i.v. prophylaxis of HBV reinfection in patients after OLT. In combination with lamivudine, long-term i.m. HBIG therapy is as efficient as i.v. HBIG treatment, but its lower costs clearly favour its use in preventing HBV reinfection after OLT.
