Eur J Clin Invest 2021; 51:e13575. [PMID: 33866547 PMCID: PMC8365701 DOI: 10.1111/eci.13575] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [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
Antiviral therapy using newer nucleos(t)ide analogues with lower resistance rates, such as entecavir or tenofovir, suppress hepatitis B virus (HBV) replication, improve liver function in patients with compensated or decompensated cirrhosis, and delay or obviate the need for liver transplantation in some patients. After liver transplantation, the combination of long-term antiviral and low-dose hepatitis B Immune globulin (HBIG) can effectively prevent HBV recurrence in greater than 90% of transplant recipients. Some forms of HBV prophylaxis need to be continued indefinitely after transplantation but, in patients with a low-risk of HBV recurrence (i.e., HBV DNA levels undetectable before transplantation), it is possible to discontinue HBIG and maintain only long-term nucleos(t)ide analogue(s) therapy. A more cautious approach is necessary for those patients with high pretransplant HBV DNA levels, those with limited antiviral options if HBV recurrence occurs (i.e., HIV or hepatitis D virus coinfection, preexisting drug resistance), those with a high risk of hepatocellular carcinoma recurrence, and those at risk of noncompliance with antiviral therapy. In this group, HBIG-free prophylaxis cannot be recommended. The combination of long-term antiviral and low-dose Hepatitis B Immune globulin (HBIG) can effectively prevent HBV recurrence in > 90% of liver transplant recipients. In patients with low HBV DNA levels, nucleos(t)ide analogue(s) treatment without HBIG is possible.

Abstract
The combination of hepatitis B immune globulin with entecavir or tenofovir (at least for a certain period of time) seems to be the most reasonable prophylaxis against recurrent hepatitis B after liver transplantation. Entecavir represents an attractive option for treatment of naïve kidney transplant recipients, because of its high efficacy and the low rates of resistance. However antiviral treatment should be individualized in the view of kidney function and the previous resistance. To date, new captivating therapeutic strategies could make interferon-free regimens viable for treatment of hepatitis C virus positive liver transplant recipients. The recent combinations of sofosbuvir with simeprevir or daclatasvir or ledipasvir plus/minus ribavirin have boosted the on treatment and sustained virological response to rates approaching 100% within liver transplant recipients with recurrent chronic hepatitis C (CHC). Preliminary data showed that the second generation direct oral antivirals could result to high treatment rates of recurrent CHC in kidney transplant recipients as well. Ongoing studies will clarify the optimal treatment of recurrent CHC in kidney transplant recipients.

Abstract
A few decades ago, liver transplantation in patients with chronic hepatitis B virus (HBV) infection was considered a relative contraindication because of the high rate of graft infections and poor prognosis. Since then, remarkable progress was introduced by using nucleos(t)ide analogues and/or hepatitis B immunoglobulin (HBIg) and liver transplantation for HBV-related disease is now becoming one of the good indication. However, high cost burden is the main problem for this combination prophylaxis for a long time use, and this issue should be emerged to be resolved. In this review, we show the progress of post anti-HBV strategies showing the history from introduction of HBIg and nucleos(t)ide analogues to recent new strategies with hepatitis B vaccine or saving or stopping protocols of HBIg, and clarify and discuss how to do for further improvement of prevention strategies with better quality.

Abstract
Background & Aims Application of nucleoside analogues and hepatitis B immunoglobulin (HBIG) has reduced hepatitis B virus (HBV) recurrence rate after liver transplantation (LT) dramatically. Recent data suggests therapy without HBIG is also effective. We sought to evaluate the necessity of HBIG in prophylaxis of HBV recurrence after LT. Methods A meta-analysis was performed. PubMed/MEDLINE, Web of Knowledge and other databases were searched for eligible literatures. The major end points were recurrence rate, patient survival, and YMDD mutant. Risk difference (RD) or risk ratio (RR) was calculated to synthesize the results. Results Nineteen studies with a total of 1484 patients were included in this analysis. Application of HBIG was helpful to reduce HBV recurrence [P<0.001; RD = 0.16; 95% confidence interval (CI)(0.12, 0.20)] and virus mutants [P<0.001; RR = 3.13; 95%CI (1.86–5.26)], it also improved patients' 1-year [P = 0.03; RD = 0.08; 95%CI (0.01, 0.15)] and 3-year survival rates [P = 0.005; RD = 0.17; 95%CI(0.05, 0.28)]. No significant difference was found for patients' 5-year survival [P = 0.46; RD = −0.06; 95%CI (−0.21, 0.10)]. Sub-group analysis showed that in patients with positive pre-operative HBV DNA status, HBIG was necessary to reduce HBV recurrence rate (P<0.001; RD = 0.42; 95%CI (0.32, 0.52)). In patients with negative HBV DNA, combined therapy gained no significant advantages (P = 0.18; RD = 0.06; 95%CI (−0.03, 0.14)). Non-Lamivudine (non-LAM) antiviral drugs performed as well as combination therapy in prophylaxis of HBV recurrence after LT (P = 0.37; RD = 0.06; 95%CI (−0.02, 0.14)). Conclusions HBIG with nucleoside analogues is helpful to reduce HBV recurrence and virus mutants. The necessity of HBIG in prophylaxis of HBV recurrence after LT when using new potent nucleoside analogues, especially for patients with negative pre-transplant HBV DNA status remains to be evaluated.

Abstract
Antiviral therapy using newer nucleos(t)ide analogs with lower resistance rates could suppress hepatitis B virus (HBV) replication, improve liver function in patients with compensated or decompensated cirrhosis, delay or obviate liver transplantation in some patients, and reduce the risk of HBV recurrence. Some form of HBV prophylaxis needs to be continued indefinitely posttransplant. However, in patients with a low-risk of HBV recurrence it is possible to discontinue hepatitis B immunoglobulins and maintain long-term nucleos(t)ide analog therapy. Currently, treatment of posttransplantation hepatitis B is a less important clinical problem than it was historically because effective antiviral therapies exist to rescue patients who failed initial prophylaxis.

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
A wide variety of commercial assays is available for the detection of hepatitis B surface antigen (HBsAg). Clearly, the sensitivity of an assay to detect a variant is dependent on the anti-HBs usage. Thus, it is not surprising that there are examples of variants that cannot be detected by all assays. Data from Europe, Asia and Africa about HBsAg variants which are not recognized by either monoclonal or polyclonal antibodies specific for wild-type group 'a' determinant, but positive by DNA polymerase chain reaction (PCR) in chronic patients and from vaccinated children are increasing. This would impose a challenge for public health issues of hepatitis B virus. In this review we tried to summarize the discrepancies between results of HBsAg assays and to explain some rationales for these inconsistencies.

Abstract
INTRODUCTION The nucleotide analogue adefovir dipivoxil (ADV) was approved in 2002 for the treatment of chronic infection with hepatitis B virus (HBV), in both hepatitis B e antigen (HBeAg)-positive and -negative patients. ADV 10 mg daily has been associated with improved liver histology, decreased levels of HBV DNA and alanine aminotransferase (ALT), and seroconversion of HBeAg. AREAS COVERED This paper reviews the use of ADV as a first-line treatment for chronic hepatitis B and as an add-on therapy in chronic HBV-infected patients with lamivudine resistance. In the years since its launch, clinical resistance to ADV has emerged, and tenofovir and entecavir have shown greater efficacy in reducing viral load. EXPERT OPINION Many patients who started antiviral therapy with ADV (either as monotherapy or in combination with lamivudine) remain on this agent because they have undetectable viremia, but its future use will probably diminish because of the availability of more potent drugs. ADV is generally well tolerated, though the 10 mg dose is associated with low risk of nephrotoxicity.

Abstract
CONTEXT Liver transplantation is the best treatment option for end-stage liver disease following hepatitis B (HBV) infection. However, the high rate of recurrence of HBV infection following transplantation is a disadvantage of this option. EVIDENCE ACQUISITION Over the past 2 decades, the gold standard of prophylactic treatment for the prevention of HBV re-infection following liver transplantation has been the administration of low- to high-dose hepatitis B immune globulin (HBIg) along with an antiviral agent to induce passive immunity. RESULTS The effectiveness of HBIg in preventing the recurrence of HBV depends on the dosage, route of administration, and duration of HBIg treatment, and the viremic status at the time of transplantation. There is currently no consensus on a standardized recommendation for therapeutic options that include HBIg administration. CONCLUSION This review attempts to summarize the available data on the feasibility of such options. Most recent studies support the use of long-term combination therapy of HBIg and antiviral NAs (especially new agents).

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 & AIMS HBV reactivation after liver transplantation may be related to persistence of covalently closed circular (ccc) DNA. We investigated the safety of HBV prophylaxis withdrawal in selected HBV transplanted patients. METHODS Thirty patients transplanted 64-195months earlier (23 males, median age 56yrs), HBsAg-positive, HBeAg, and HBV-DNA negative at transplant (43% HCV/HDV co-infected), with undetectable intrahepatic total and ccc-DNA were enrolled. All patients underwent HBIg withdrawal and continued lamivudine with monthly HBsAg and HBV-DNA monitoring and sequential liver biopsies. Those with confirmed intrahepatic total and ccc-DNA undetectability 24weeks after stopping HBIg, also underwent lamivudine withdrawal and were followed-up without prophylaxis. RESULTS Twenty-five patients did not exhibit signs of HBV recurrence after prophylaxis withdrawal (median follow-up 28.7months, range 22-42). Five patients became HBsAg-positive: one early after HBIg withdrawal, the other four after HBIG and lamivudine withdrawal. None of these patients experienced clinically relevant events. In the first patient, HBIg were reinstituted with prompt HBsAg negativization. Of the other four, one remained HBsAg-positive with detectable HBV-DNA and mild ALT elevation and was successfully treated with tenofovir. In the remaining three, HBsAg positivity was transient and followed by anti-HBs seroconversion, thus no antiviral treatment was needed. CONCLUSIONS Patients with undetectable HBV viremia at transplant and no evidence of intrahepatic total and cccDNA may safely undergo cautious weaning of prophylaxis, showing low rate of HBV recurrence after a 2 year follow-up. Undetectability of intrahepatic ccc-DNA may help to identify patients at low-risk of recurrence, yet studies with longer follow-up are needed.

Sustained eradication of hepatitis C virus by low-dose long-term interferon therapy in a renal transplant recipient with dual infection with hepatitis B and C viruses: a case report.

Abstract
Introduction Accelerated liver function deterioration has been recognized in renal transplant recipients infected with hepatitis C virus (HCV). Although combination therapy with interferon plus ribavirin has been established as the standard treatment for patients with chronic HCV, the high risk of allograft rejection associated with interferon therapy has greatly discouraged the clinical use of this regimen. In Asia, where chronic hepatitis B virus (HBV) is prevalent, dual infection with HBV and HCV poses an even greater challenge for clinical hepatologists. Case presentation In this article, we report the case of a 51-year-old Taiwanese man with dual infection with HBV and HCV prior to renal transplantation. Low-dose interferon (3 to 6 × 106 U/week) and ribavirin (100 mg/day to 200 mg/day) were prescribed following the reactivation of the man's HCV after renal transplantation. Additionally, lamivudine (100 mg/day) was administered concomitantly to prevent HBV reactivation. His initial serum HCV RNA concentration was 5.2 × 106 copies/mL (genotype 2a). After three and one-half years of antiviral therapy, his HCV was successfully eradicated without any episodes of allograft rejection. His serum HCV RNA remained negative six months after withdrawal from interferon and ribavirin treatment. His serum HBV DNA remained undetectable throughout the course of therapy. Conclusion Low-dose, long-term interferon therapy may achieve sustained eradication of HCV in the renal transplant recipient with dual infection with HBV and HCV.

Abstract
BACKGROUND Combination of nucleos(t)ide analogue and anti-HBs immunoglobulin (HBIg) is the standard protocol for prevention of HBV reactivation after liver transplantation, but because of the extremely high cost of HBIg, HBV vaccine is tried as a much cheaper and potentially safer substitute. Here we show the different effect of HBV vaccine between chronic HBV carrier and non-HBV patients who received grafts from HBc antibody-positive donors. METHODS Fifteen chronic HBV carriers and 6 non-HBV patients who received grafts from HBc antibody-positive donors were included in this study. These patients received double dose of pre-S-containing HBV vaccine every month from later than 12 months after liver transplantation. Successful vaccination was defined as HBsAb >100 IU/l without HBIg administration for 3 months. RESULTS None of the 15 chronic HBV carriers succeeded in maintaining high enough HBsAb titers. In contrast, 5 of 6 non-HBV patients with HBcAb-positive donors achieved HBsAb >100 IU/l without HBIg coadministration. Recipient HBV status (HBV carrier/non-HBV) was considered to have a stronger effect on vaccine success (p < 0.001) though recipient age (p = 0.006) was also selected as a significant factor. CONCLUSIONS Recipient HBV status seems to be the most important factor affecting success of HBV vaccine after liver transplantation. In non-HBV patients who received grafts from HBcAb-positive donors, HBV vaccination is an effective, cost-saving, and safe method for prevention of HBV reactivations. In contrast in chronic HBV patients, response rate was quite poor, so some modifications such as combination with adjuvant or modification of administration schedules should be considered.

Abstract
OBJECTIVE To investigate lamivudine (LAM)-resistance profiles of hepatitis B virus (HBV) at the early stages of virological breakthrough (serum HBV-DNA 12-345IU/ml) or when HBV-DNA is undetectable. METHODS Sixty-four HBV-mono-infected patients were enrolled: 25 had virological breakthrough with serum HBV-DNA ranging from 12 to 345IU/ml during first-line LAM-monotherapy; 24 were on LAM-monotherapy, and 15 were on LAM+adefovir dipivoxil (ADV) with undetectable serum HBV-DNA (<12IU/ml). RESULTS HBV-reverse transcriptase was successfully sequenced in 22 (88.0%) LAM-treated patients with HBV-DNA between 12 and 345IU/ml, and in 12 (30.8%) patients receiving LAM (±ADV) with HBV-DNA<12IU/ml. Drug-resistance mutations were observed in 17 (77.2%) LAM-treated patients with virological breakthrough: 8 M204V, 7 M204I, 1 M204I/V, and 1 A181T. One or ≥2 compensatory mutations were found in 10 (58.8%) and in 4 (23.5%) patients. Drug-resistance mutations were present also in patients with undetectable serum HBV-DNA: M204I was detected in 2 patients receiving LAM-monotherapy, and V84M in 1 patient receiving LAM+ADV. CONCLUSION Overall findings support the existence of drug-resistance mutations even at very low levels of viral replication. The persistence of low-level HBV replication and consequent drug-resistance emergence should be considered when choosing therapeutic strategies.

Abstract
During the next few decades, vaccination against hepatitis B virus (HBV) will dramatically change the epidemiological profile of this worldwide infection especially when Heath Policies encourage including HBV vaccination program for the newborns. However, it is still estimated that more than 2000millions living people have met HBV. Symptomatic hepatitis with jaundice is less frequent than asymptomatic infection; however, as much as 350millions of individuals remain chronically infected by HBV. In these cases, the need for efficient antiviral therapy remains clear when a viral replication is observed to control the risk of progression and the need for liver transplantation, which represents the only end-stage treatment. Indeed, patients having chronic hepatitis B (CHB) can now be successfully treated using nucleos(t)ide analogs (NA) or pegylated interferon (PEG-IFN). Therefore, beside vaccination, prevention of the progression of the disease to cirrhosis and liver decompensation, leading to end-stage liver disease and/or to hepatocellular carcinoma, by inhibiting viral replication seems to represent the best approach to improve survival. At last but not least, co-morbidities and other viral infections, leading also to chronic liver cirrhosis or liver inflammation such as the specific satellite delta virus (HDV), human immunodeficency virus (HIV) and/or hepatitis C (HCV) virus, are able to accelerate the progression and have to be taken in account. Interestingly, in treated infection, the dogma of the irreversibility of the liver fibrosis, when the cirrhosis is constituted, is tumbling down. In this review, we will focus on the clinical, virological and therapeutic aspects of hepatitis B infection in order to expose the proposals to follow-up and treat HBV-infected patients and the prevention of drug-resistant HBV mutants that frequently arise, leading to treatment failure and progression to liver disease.

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
PURPOSE OF REVIEW The established gold standard for prophylaxis against hepatitis B virus (HBV) recurrence post-liver transplant is combination hepatitis B immune globulin (HBIG) and lamivudine. This therapy reduces the risk of recurrence to less than 5% at 5 years; however, the cost of HBIG has led to the investigation of alternatives. This paper reviews the HBIG-sparing alternatives achieved with lamivudine and the prospects for the newer anti-HBV agents in post-liver transplant prophylaxis. RECENT FINDINGS When used with lamivudine as part of combination prophylaxis, low-dose intramuscular HBIG is equivalent to high-dose intravenous HBIG. There is recent evidence that in patients receiving HBIG/lamivudine, HBIG can be replaced with adefovir dipivoxil at 6-12 months post-liver transplant without precipitating recurrence. Furthermore, a recent study showed that primary prophylaxis with combination adefovir/lamivudine therapy without the use of long-term HBIG was effective and well tolerated as primary prophylaxis. SUMMARY Although there are few studies of potent newer anti-HBV agents such as entecavir or tenofovir being used as HBV prophylaxis, the properties of these drugs suggest that they should replace lamivudine within HBV prophylaxis regimes.

Abstract
In patients receiving orthotopic liver transplantation, hepatitis B recurrence rates have decreased significantly with the use of various methods for prophylaxis. At present, a combination of hepatitis B immunoglobulin (HBIG) and lamivudine is the standard of care, resulting in recurrence rates of 0% to 11%. Recent data suggest that the addition of adefovir to lamivudine is successful in treating patients with recurrent hepatitis B infection. A Markov model was used to compare costs and outcomes of 2 strategies for hepatitis B prophylaxis 1 year after transplantation. The first consisted of prophylaxis with lamivudine and adefovir (strategy 1), whereas the second consisted of intramuscular HBIG and lamivudine (strategy 2) with the addition of adefovir in patients who subsequently developed hepatitis B recurrence. Patients who failed with adefovir and lamivudine were then treated with tenofovir and entecavir. 16.8% of liver transplant recipients had hepatitis B recurrence after 10 years of treatment with lamivudine and HBIG. The medical costs for strategy 1 and strategy 2 after 10 years of therapy were $151,819 and $166,246, respectively, and this resulted in cost savings of $14,427. The decision analysis model began 1 year after liver transplantation. A 1-way sensitivity analysis demonstrated that the model was most sensitive to cost changes of adefovir and HBIG injections as well as variations in the hepatitis B virus recurrence rate. The model was robust to costs of lamivudine, laboratory costs, administrative fees, and office visit fees. Our decision analysis model resulted in marked savings in costs with strategy 1 (lamivudine and adefovir), providing pharmacoeconomic support for the use of this strategy as first-line therapy in hepatitis B prophylaxis in liver transplant recipients 1 year after liver transplantation.

Abstract
Liver transplantation (LT) in patients with hepatitis B virus (HBV) infection is associated with a high rate of graft loss and poor survival, unless re-infection can be prevented. Human hepatitis B immune globulin (HBIG) and nucleoside analogues (NA) have long been utilized to prevent re-infection. Previously, we generated a human monoclonal antibody (mAb), HB that recognizes the surface antigen of hepatitis B virus (HBV). We have constructed a secreted version of HB and cloned its genes into recombinant adeno-associated virus (AAV). We compared the efficiency of AAV vector after a single injection via intramuscular or intravenous routes without additional intervention. Then, we evaluated the activity of antibody HB in tree shrews treated with rAAV-HB and in vitro experiments. So, intramuscular injection of rAAV-HB was a suitable method for the immunoprophylaxis of HBV infection. This human antibody will be useful for the immunoprophylaxis of HBV infection.
