Reestablishment of active immunity against HBV graft reinfection after liver transplantation for HBV-related end stage liver disease. J Immunol Res 2014; 2014:764234. [PMID: 25759834 PMCID: PMC4352506 DOI: 10.1155/2014/764234] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2014] [Accepted: 11/18/2014] [Indexed: 02/05/2023] Open
Abstract
Background. The aim of this study was to establish a hepatitis B virus (HBV) vaccination protocol among orthotopic liver transplantation (OLT) recipients under the coverage of a low-dose hepatitis B immunoglobulin (HBIG) combined with an antiviral agent prophylaxis protocol. Method. Two hundred OLT recipients were included in this study. The vaccine was injected at months 0, 1, 2, and 6. Low-dose HBIG combined with antiviral agent prophylaxis protocol was continued before reestablishment of active immunity against HBV in order to maintain a steady anti-HBs titer. Results. Active immunity against HBV was reestablished in 50 patients, for an overall response rate of 25%. Of the 50 patients, 24 discontinued HBIG without any HBV graft reinfection during a follow-up period of 26.13 ± 7.05 months. 21 patients discontinued both HBIG and antiviral agents during a follow-up period of 39.86 ± 15.47 months, and 4 patients among them appeared to be HBsAg positive. There was no recipient death or graft loss because of HBV reinfection. Conclusions. Vaccination preventing HBV reinfection for OLT recipients is feasible. The strategy withdrawal of HBIG with induction of active immunity against hepatitis B is reasonable for long-term survivors of OLT; however, discontinuation nucleoside analogues should be cautious.

Abstract
Hepatitis B virus (HBV) continues to be a major cause of morbidity and mortality worldwide. It is estimated that about 350 million people throughout the world are chronically infected with HBV. Some of these people will develop hepatic cirrhosis with decompensation and/or hepatocellular carcinoma. For such patients, liver transplantation may be the only hope for cure or real improvement in quality and quantity of life. Formerly, due to rapidity of recurrence of HBV infection after liver transplantation, usually rapidly progressive, liver transplantation was considered to be contraindicated. This changed dramatically following the demonstration that hepatitis B immune globulin (HBIG), could prevent recurrent HBV infection. HBIG has been the standard of care for the past two decades or so. Recently, with the advent of highly active inhibitors of the ribose nucleic acid polymerase of HBV (entecavir, tenofovir), there has been growing evidence that HBIG needs to be given for shorter lengths of time; indeed, it may no longer be necessary at all. In this review, we describe genetic variants of HBV and past, present, and future prophylaxis of HBV infection during and after liver transplantation. We have reviewed the extant medical literature on the subject of infection with the HBV, placing particular emphasis upon the prevention and treatment of recurrent HBV during and after liver transplantation. For the review, we searched PubMed for all papers on the subject of "hepatitis B virus AND liver transplantation". We describe some of the more clinically relevant and important genetic variations in the HBV. We also describe current practices at our medical centers, provide a summary and analysis of comparative costs for alternative strategies for prevention of recurrent HBV, and pose important still unanswered questions that are in need of answers during the next decade or two. We conclude that it is now rational and cost-effective to decrease and, perhaps, cease altogether, the routine use of HBIG during and following liver transplantation for HBV infection. Here we propose an individualized prophylaxis regimen, based on an integrated approach and risk-assessment.

Abstract
The combination of nucleos(t)ide analogues (NAs) and hepatitis B immune globulin has been established as safe and effective prophylaxis against hepatitis B virus (HBV) reactivation after liver transplantation (LT). However, the essential weak point of this regimen is its high cost. The hepatitis B (HB) vaccine is an attractive alternative that costs less, and it enables some patients to have sufficiently high hepatitis B surface antibody (HBsAb) titers. Almost no data exist on whether NAs can be stopped safely in such successfully vaccinated patients. We investigated the incidence of HB vaccine escape mutants in liver recipients who had sufficient HBsAb titers after LT and stopped NAs. Among 18 HBV carriers and 7 non-HBV patients who received grafts from hepatitis B core antibody-positive donors, 2 HBV carriers and 6 non-HBV patients who achieved HBsAb titers >100 IU/L for >3 months after posttransplant vaccination were weaned from NAs. For the patients who showed viremia, we analyzed amino acid sequences of the HB envelope protein, and we performed a statistical analysis for the factors associated with viremia. In 4 of the 8 patients who achieved sufficient HBsAb levels after vaccination and stopped NAs, HBV DNA appeared after a median of 12 months. A sequence analysis showed various amino acid mutations, including the a-determinant, in the HB envelope region. Frequent vaccination was shown to be a statistically significant risk factor for inducing viremia. In conclusion, although the HB vaccine is an effective substitute for prophylaxis against HBV reactivation in some patients after LT, frequent vaccination could be a risk factor for producing escape mutants. Our data demonstrate not only that caution must be exercised in stopping NAs in effectively vaccinated patients (especially in patients vaccinated frequently) but also that it is important to set stopping rules for vaccination in transplant patients.

Contradictory immune response in post liver transplantation hepatitis B and C. Int J Inflam 2014; 2014:814760.

Abstract
Hepatitis B and C often progress to decompensated liver cirrhosis requiring orthotopic liver transplantation (OLT). After OLT, hepatitis B recurrence is clinically controlled with a combination of hepatitis B immunoglobulin (HBIG) and nucleos(t)ide analogues. Another approach is to induce self-producing anti-hepatitis B virus (HBV) antibodies using a HBV envelope antigen vaccine. Patients who had not been HBV carriers such as acutely infected liver failure or who received liver from HBV self-limited donor are good candidate. For chronic HBV carrier patients, a successful response can only be achieved in selected patients such as those treated with experimentally reduced immunosuppression protocols or received an anti-HBV adaptive memory carrying donor liver. Hepatitis C virus (HCV) reinfects transplanted livers at a rate of >90%. HCV reinfected patients show different severities of hepatitis, from mild and slowly progressing to severe and rapidly progressing, possibly resulting from different adaptive immune responses. More than half the patients require interferon treatment, although the success rate is low and carries risks for leukocytopenia and rejection. Managing the immune response has an important role in controlling recurrent hepatitis C. This study aimed to review the adaptive immune response in post-OLT hepatitis B and C.

Abstract
BACKGROUND AND AIMS Antiviral prophylaxis with hepatitis B immunoglobulin (HBIg) plus lamivudine reduces the risk of hepatitis B virus (HBV) recurrence after HBV-related liver transplant (LT). However, HBIg is expensive, and lamivudine therapy is limited by drug resistance. This study assessed a pilot study of entecavir plus low-dose, on-demand HBIg in preventing HBV recurrence after LT. METHODS Between 2006 and May 2011, approximately 145 patients undergoing HBV-related LT and receiving entecavir plus low-dose, on-demand HBIg were enrolled and followed for a median of 36 months. A historical control group of 171 patients undergoing HBV-related LT between 1998 and 2010 and receiving lamivudine plus HBIg were followed for a median of 77 months. The primary end point was the proportion of patients with recurrent HBsAg-positivity. RESULTS In the entecavir cohort, 2 (1.37%) of 145 patients experienced HBV recurrence, none of which had evidence of viral resistance. In the lamivudine cohort, 11 (6.4%) of 171 cases of HBV recurrence were observed, 5 of which were associated with lamivudine resistance. The cumulative probabilities of HBV recurrence were significantly different between both cohorts (P=0.055). HBsAg recurrence was associated with lower overall survival (P<0.001), even in patients with undetectable HBV DNA. Using pooled data from both cohorts, predictors of HBV recurrence were nucleoside selection, pre-LT hepatocellular carcinoma, post-LT low anti-HBs, male sex, and HBsAg-positivity in the explant liver tissue. CONCLUSIONS Entecavir plus low-dose, on-demand HBIg resulted in a low rate of HBV recurrence without evidence of resistance development and provided an effective and cost-saving strategy for patients having HBV-related LT.

Abstract
Non-responsiveness to conventional hepatitis B vaccines in individuals at high risk of exposure to hepatitis B virus (HBV) is an important public health problem and of particular relevance in health care providers. Yeast-derived conventional HBsAg vaccines fail to induce protective antibody titers in up to 10% of immune competent vaccinees. Therefore, a third generation HBV vaccine, Sci-B-Vac™, was developed which contains in addition to the small S antigen the PreS1 and PreS2 antigens. This vaccine proved to induce a highly potent cellular and humoral immune response in healthy individuals as well as protective antibody levels in non- and low-responders to conventional HBV vaccines. The aim of the study was to examine whether Sci-B-Vac™ triggers cellular and humoral immunity in individuals who failed immunization with conventional vaccines. We immunized 21 volunteers (15 non- and 6 low-responders) according to the standard vaccination schedule (0, 4 and 24 weeks), determined the cellular immunity by proliferation assay and interferon (IFN)-γ ELISpot and measured the anti-HBs antibody titers prior to each vaccination and four weeks after the third vaccine dose. Following three vaccinations, PreS/S-specific T-cell proliferation was detected in 8 out of 15 non-responders and 5 out of 6 low-responders. Specific IFN-γ responses were measured in 2 out of 15 non-responders and 4 out of 6 low-responders. All but one (20/21) study participants developed anti-HBs titers ≥10IU/l after three vaccinations. Anti-HBs ≥100IU/L were detected in 12 out of 15 non-responders and in 6 out of 6 low-responders. Anti-HBs ≥10IU/l and <100IU/l were found in 2 non-responders. These results indicate that Sci-B-Vac™ induces cellular immunity as well as protective anti-HBs antibody titers in non- and low-responders. In conclusion, these results confirm that Sci-B-Vac™ should be administered to non-responders to conventional HBV vaccines and patients with impaired immune function.

Abstract
In the current study we aimed to show the common YMDD motif mutations in viral polymerase gene in chronic hepatitis B patients during lamivudine and adefovir therapy. Forty-one serum samples obtained from chronic hepatitis B patients (24 male, 17 female; age range: 34-68 years) were included in the study. HBV-DNA was extracted from the peripheral blood of the patients using an extraction kit (Invisorb, Instant Spin DNA/ RNA Virus Mini Kit, Germany). A line probe assay and direct sequencing analyses (INNO-LIPA HBV DR v2; INNOGENETICS N.V, Ghent, Belgium) were applied to determine target mutations of the viral polymerase gene in positive HBV-DNA samples. A total of 41 mutations located in 21 different codons were detected in the current results. In 17 (41.5%) patients various point mutations were detected leading to lamivudin, adefovir and/ or combined drug resistance. Wild polymerase gene profiles were detected in 24 (58.5%) HBV positive patients of the current cohort. Eight of the 17 samples (19.5%) having rtM204V/I/A missense transition and/or transversion point mutations and resistance to lamivudin. Six of the the mutated samples (14.6%) having rtL180M missense transversion mutation and resistance to combined adefovir and lamivudin. Three of the mutated samples (7.5%) having rtG215H by the double base substituation and resistance to adefovir. Three of the mutated samples (7.5%) having codon rtL181W due to the missense transversion point mutations and showed resistance to combined adefovir and lamivudin. Unreported novel point mutations were detected in the different codons of polymerase gene region in the current HBV positive cohort fromTurkish population. The current results provide evidence that rtL180M and rtM204V/I/A mutations of HBV-DNA may be associated with a poor antiviral response and HBV chronicity during conventional therapy in Turkish patients.

Abstract
The purpose of this study was to identify the factors associated with the recurrence of hepatitis B virus (HBV) following liver transplantation (LT) for HBV-related disease and to recognize the outcome of treatment for HBV recurrence with oral nucleos(t)ide analogues. Six hundred and sixty-seven LTs were performed for HBsAg-positive adult patients in our institute from 1996 to 2010. HBV prophylaxis was performed by hepatitis B immunoglobulin (HBIG) monotherapy or HBIG and entecavir combination therapy. There were 63 cases (11.4%) of HBV recurrences during a median follow-up of 51 months. The median time to HBV recurrence was 22 months. A preoperative HBV DNA load of more than 10(5) IU/mL, HBIG monotherapy, and hepatocellular carcinoma in the explant liver were independent risk factors for HBV recurrence following LT in multivariate analysis. Patient survival at 10 yr was 54.2% for HBV-recurrent patients. Among patients with HBV recurrence, HBsAg seroclearance was achieved in 13 patients (20.6%), but HBsAg seroclearance did not affect survival in these patients after the recurrence of HBV (p = 0.28). The recurrence of HBV led to graft failure in six cases. HBV recurrence should be prevented by strict management of pre-transplant HBV viremia and an effective post-transplant HBV prophylaxis.

Abstract
BACKGROUND AND AIM Liver transplantation (LT) for hepatitis B virus (HBV)-related disease can be complicated by HBV recurrence. The aim of this study was to evaluate the risk factors, prophylaxis treatment, and histological characteristics of HBV recurrence after LT when using long-term, low-dose hepatitis B immunoglobulin (HBIG) plus nucleoside analog (lamivudine [LAM] or entecavir [ETV]). METHODS Retrospective data from 253 adult LT patients using long-term, low-dose HBIG plus nucleoside analog after LT, for a mean treatment duration of 1-72 months, were collected from a single center in Beijing, China. Univariate analyses were conducted to determine the association among gender, age, hepatocellular carcinoma, hepatitis B e antigen-positive status, HBV-DNA level and tyrosine-methionine-aspartate-aspartate (YMDD) mutations on HBV recurrence in these patients. RESULTS Overall, the HBV recurrence rate was 6.32% (16/253). There was no significant difference in the survival rate between the HBV recurrence and non-recurrence groups. Risk factors for HBV recurrence were: hepatitis B e antigen positivity, HBV-DNA > 10(5) copies/mL, hepatocellular carcinoma, and YMDD mutation. Sixteen patients receiving LAM had HBV recurrence (16/169; mean treatment duration: 61.8 ± 18.3 months). No HBV recurrence occurred in patients receiving ETV after LT (0/84; mean treatment duration: 57.1 ± 15.9 months). Differences in rate of mortality and HBV recurrence were not significant between the two groups. CONCLUSIONS LT is an effective treatment for HBV-related end-stage liver disease. The combination of ETV and intramuscular HBIG for HBV recurrence prophylaxis after LT was more effective than LAM, especially in Chinese patients with HBV recurrence risk factors.

Abstract
BACKGROUND Hepatitis B immunoglobulin (HBIG) given in combination with a nucleos(t)ide analogue has reduced the rate of recurrent hepatitis B virus (HBV) infection following liver transplantation (LT); however, the most effective protocol remains unclear. OBJECTIVE To evaluate the use of tenofovir disoproxil fumarate (TDF) in combination with one year of low-dose HBIG. METHODS Twenty-four adults who underwent LT for HBV-related liver disease at the University Health Network (Toronto, Ontario) and received TDF (± lamivudine) and one year of HBIG to prevent recurrent HBV infection from June 2005 to June 2011 were evaluated. RESULTS The median length of follow-up post-LT was 29.1 months. Three patients died during the follow-up period. Patient survival was 100% and 84.1% at one and five years, respectively. None of the patients developed recurrent HBV infection. No significant adverse event was observed due to TDF administration; renal function pre- and post-LT were also acceptably preserved. CONCLUSION The present study demonstrated that a short, finite course of low-dose HBIG combined with maintenance of long-term TDF staring before LT is cost-effective and safe. However, further prospective study involving a larger patient cohort with a longer follow-up period is required to confirm the results.

Abstract
Exacerbations of chronic hepatitis B are common in endemic countries. Acute exacerbation of chronic hepatitis B virus (CHB-AE) causing derangement of liver functions may be seen in a flare of HBV in immune clearance phase or as a reactivation of HBV in patients with inactive or resolved HBV infection. While reactivation of HBV is usually seen in HBsAg positive patients, it is being increasingly recognized in patients with apparently resolved HBV infection who do not have HBsAg in serum but have IgG antibody to core antigen (anti-HBc) in the serum, especially so in patients on chemotherapy, immunosuppressive therapy or undergoing hematopoietic stem cell transplantation. In an icteric patient who is HBsAg positive, it may be difficult to differentiate CHB-AE from acute viral hepatitis B (AVH-B). Both may have similar clinical presentation and even IgM anti-HBc, the traditional diagnostic marker of AVH-B, may also appear at the time of exacerbation of CHB. The differentiation between CHB-AE and AVH-B is important not only for prognostication but also because management strategies are different. Most cases of AVH-B will resolve on their own, HBsAg clearance is achieved spontaneously in 90-95% of adults and treatment is rarely indicated except in the few with severe/fulminant disease. In contrast, in CHB-AE, the onset of jaundice may lead to decompensation of liver disease and treatment is warranted. The mechanisms of acute exacerbation and the differentiating features between AVH-B and CHB-AE are reviewed.

Abstract
AIM Recently, knowledge for indications of living donor liver transplantation (LDLT) has been robustly accumulated in. For further improvement, risks should be reexamined in recent cases. In this study, we investigated preoperative risk factors in cirrhotic patients who underwent LDLT in recent era. METHODS Seventy-four cirrhotic patients who underwent LDLT at our institution between 2003 and 2011 were included. Recipient and donor age and sex, existence of hepatocellular carcinoma (HCC), preoperative Model for End-Stage Liver Disease score, fasting blood glucose (FBG), triglyceride, total cholesterol, serum creatinine, hemoglobin A1c, graft : recipient weight ratio, ABO compatibility and choice of calcineurin inhibitor were analyzed. A proportional hazard model was applied and P < 0.05 was considered statistically significant. RESULTS In multivariate analysis, recipient age (hazard ratio = 1.188, P = 0.011) and FBG (hazard ratio = 1.009, P = 0.016) showed as significant independent factors. Theoretical mortalities were 9.2%, 21.9% and 51.7% in patients with normal FBG at 55, 60 and 65 years old, respectively, and 34.3% and 53.6% in patients with FBG of 150 and 200 mg/dL, respectively, at 60 years old. CONCLUSION Recipient age and FBG remain important risk factors for LDLT in cirrhotic patients even in the recent era. These factors should be considered for selecting liver transplant candidates in cirrhotic patients.

Abstract
BACKGROUND Recurrence of hepatitis B virus (HBV) infection after liver transplantation can lead to graft loss and a reduction in long-term survival. The purpose of this review is to summarize the current therapeutic options for preventing HBV recurrence in liver transplant recipients. DATA SOURCES Up to January 2013, studies that were published in MEDLINE and EMBASE on prevention of HBV recurrence after liver transplantation were reviewed. RESULTS There have been remarkable advancements in the past two decades on the prevention of HBV recurrence after liver transplantation, from the discovery of hepatitis B immune globulin (HBIG) and lamivudine monotherapy to the combination therapy using HBIG and lamivudine. With the development of newer and stronger antiviral agents, the need for life-long HBIG is doubtful. With their low resistance profile, oral antiviral prophylaxis using these new agents alone is sufficient and is associated with excellent outcome. CONCLUSIONS Restoration of host HBV immunity with adoptive immunity transfer and vaccination may represent the ultimate strategy to withdraw prophylactic treatment and to achieve a drug free regimen against HBV recurrence after liver transplantation.

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
BACKGROUND AND AIM Currently, hepatitis B virus (HBV) re-infection after liver transplantation (LT) can be almost completely suppressed by the administration of HBV reverse transcriptase inhibitors and hepatitis B immunoglobulins. However, after transplantation, there is no indicator of HBV replication because tests for the serum hepatitis B surface antigen and HBV-DNA are both negative. Therefore, the criteria for reducing and discontinuing these precautions are unclear. In this study, we examined the serum HBV core-related antigen (HBcrAg) and intrahepatic covalently closed circular DNA (cccDNA) in order to determine if these could be useful markers for HBV re-infection. METHODS Thirty-one patients underwent LT for HBV-related liver disease at Nagasaki University Hospital from 2001 to 2010. Of these, 20 cases were followed up for more than 1 year (median follow-up period, 903 days). We measured serum HBcrAg and intrahepatic cccDNA levels in liver tissue. In addition, in nine cases, we assessed the serial changes of HBcrAg and intrahepatic cccDNA levels from preoperative periods to stable periods. RESULTS We examined serum HBcrAg and intrahepatic cccDNA levels in 20 patients (35 samples). HBcrAg and cccDNA levels were significantly correlated with each other (r = 0.616, P < 0.001). From a clinical aspect, the fibrosis stage was significantly lower in both HBcrAg- and cccDNA-negative patients than in HBcrAg- or cccDNA-positive patients. CONCLUSIONS HBcrAg and cccDNA were useful as HBV re-infection markers after LT. Keeping patients' HBcrAg and cccDNA negative after LT might contribute to long-term graft survival.

Abstract
Rates of transmission of hepatitis B virus (HBV) infection from organ donors with HBV markers to recipients along with reactivation of HBV during immunosuppression following transplantation have fallen significantly with the advent of hepatitis B immune globulin (HBIg) and effective antiviral therapy. Although the availability of potent antiviral agents and HBIg has highly impacted the survival rate of HBV-infected patients after transplantation, the high cost associated with this practice represents a major financial burden. The availability of potent antivirals with high genetic barrier to resistance and minimal side effects have made it possible to recommend an HBIg-free prophylactic regimen in selected patients with low viral burden prior to transplant. Significant developments over the last two decades in the understanding and treatment of HBV infection necessitate a re-appraisal of the guidelines for prophylaxis of HBV infection in solid organ transplant recipients.

Abstract
BACKGROUND Hepatitis B virus (HBV) relapse and/or hepatocellular carcinoma (HCC) recurrence remains a major concern for patients who undergo liver transplantation (LT) because of HBV-related HCC. This study investigates the correlation between HBV relapse and HCC recurrence and it explores factors that affect patient outcomes after LT. METHODS Between September 2002 and August 2009, 78 consecutive patients who underwent LT because of HBV-related HCC were enrolled in this study. Serum samples obtained before LT were assayed both for virological factors associated with HBV DNA and for genotypic characteristics of the virus. All patient clinicopathological features and virological factors were assessed further by univariate and multivariate analyses to determine prognostic factors. RESULTS During a median follow-up period of 29.4 months, 13 (16.6 %) patients experienced HCC recurrence and 18 (23.1 %) patients experienced HBV relapse. HBV relapse exhibited a close association with HCC recurrence (p = 0.004) and led to unfavorable overall survival after LT. Multivariate analysis of prognostic factors showed that the basal core promoter (BCP) mutation independently predicted a shorter survival period free from HBV relapse (p = 0.036). Moreover, with the exception of unfavorable tumor characteristics, the BCP mutation was found to be an important prognostic factor that affected HCC recurrence after LT (p = 0.042). CONCLUSIONS In this study, the HBV-BCP mutation was identified as an important predictor of post-LT clinical outcomes in patients with HBV-related HCC. Therefore, we recommend that aggressive antiviral treatment may be considered for patients associated with this risk factor.

Abstract
OBJECTIVES The long-term outcomes of oral antiviral therapy without hepatitis B immune globulin (HBIG) in prevention of reinfection with hepatitis B after liver transplantation are not known. We aimed to determine the long-term outcomes from a large population of chronic hepatitis B (CHB) liver transplant recipients using oral antiviral therapy alone. METHODS A total of 362 consecutive CHB patients transplanted from January 2003 to May 2011 were included. None of the patients received HBIG. Viral serology, viral load, and liver biochemistry were performed at regular intervals during follow-up. RESULTS Of the 362 patients, 176 (49%), 142 (39%), and 44 (12%) were on lamivudine (LAM), entecavir (ETV), and combination therapy (predominantly LAM+adefovir), respectively, at the time of transplant. The median follow-up length was 53 months. The rate of hepatitis B surface antigen seronegativity and hepatitis B virus (HBV) DNA suppression to undetectable levels at 8 years was 88 and 98%, respectively. The virological relapse rates (>1 log increase IU/ml) at 1, 3, 5, and 8 years was 5, 10, 13 and 16%, respectively. The virological relapse rate at 3 years for LAM, ETV, and combination group was 17, 0, and 7%, respectively (P<0.001). Forty-two patients had virological relapse, of which 36 had YMDD mutation (31 in the LAM group and 5 in the combination group). The overall 8-year survival was 83%, with no difference between the three treatment groups (P=0.94). No mortality from HBV recurrence occurred in the 362 patients. CONCLUSIONS Oral nucleoside/nucleotide analogs without HBIG are effective in preventing graft loss secondary to hepatitis B recurrence after liver transplantation. However, new agents with a high barrier to resistance should be used to minimize drug resistance and to prevent virological rebound.

Abstract
Hepatitis B immunoglobulin (HBIG), given in combination with nucleos(t)ide therapy, has reduced the rate of recurrent hepatitis B virus (HBV) following liver transplantation (LT), although the most effective protocol is unknown. We have retrospectively evaluated the use of long-term nucleos(t)ide analog in combination with one yr of low-dose HBIG. One hundred and fifty-two adults with HBV-related liver disease underwent LT in our center from January 1999 to August 2009; of these, 132 patients who received one yr of HBIG combined with long-term nucleos(t)ide analogs (largely on lamivudine [LAM] alone, n = 97) afterward were included for the purposes of this study. Median follow-up post-transplantation was 1752 d. Patient survival was 93.9%, 86.9% and 84.1% at 1, 5, and 10 yr, respectively; none of the 17 deceased patients had recurrent HBV. HBV recurrence was observed in nine patients (all received LAM+HBIG), yielding recurrence rates of 2.3%, 5.1%, and 8.6% at 1, 3, and 5/10 yr, respectively. All recurrences were successfully managed, usually with additional antiviral treatment. In conclusion, this study, with its long-term follow-up, demonstrates that short course of low-dose HBIG (without anti-HBs monitoring) combined with the use of long-term nucleos(t)ide analog is effective and less cumbersome than many protocols in current use.

Abstract
BACKGROUND In the background of availability of better treatments for specific liver diseases and listing of nonalcoholic steatohepatitis (NASH) as an etiology for liver transplantation (LT), data are unclear on the impact of disease etiology on the frequency of LT and liver posttransplantation outcomes. METHODS The United Network for Organ Sharing database (1994-2009) was queried for adults receiving first LT for primary biliary cirrhosis (PBC; n=3052), primary sclerosing cholangitis (PSC; n=3854), hepatitis C virus (HCV; n=15,147), alcoholic cirrhosis (AC; n=8940), HCV+alcohol (n=6066), NASH (n=1368), cryptogenic cirrhosis (CC; n=5856), hepatitis B virus (HBV; n=1816), and hepatocellular carcinoma (HCC; n=8588). Graft and patient survival were compared and Cox models were built to determine independent prediction of outcomes by disease etiology. RESULTS The frequency of LT increased for NASH, HCC, and HCV+alcohol, remained stable for AC, and decreased for PBC, PSC, HCV, CC, and HBV. The proportion of simultaneous liver-kidney transplants increased from approximately 3% in 2001 to 10% in 2009. Compared with PBC, 5-year graft and patient survival were (a) similar for PSC, NASH, and HBV (80-85%), (b) poorer for AC and CC (hazard ratio, 1-1.5), and (c) worst for HCV, HCV+alcohol, and HCC (hazard ratio, 1.5-2.4). Five-year outcomes for HCV-associated HCC were poorer compared with HCC due to other etiologies. CONCLUSIONS LT performed for NASH and HCC are increasing. Potent treatment options resulted in a decrease in number of transplants for HBV, HCV, and PBC. Better treatment modalities for HCV are expected to further reduce the number of LT for HCV. Excellent posttransplantation outcomes for NASH and AC are encouraging, resulting in wider acceptance of transplants for these etiologies.

Abstract
Without effective prophylaxis, liver transplantation for hepatitis B virus (HBV)-related liver disease is frequently complicated by severe and rapidly progressive HBV recurrence. Combination prophylaxis with hepatitis B immune globulin (HBIG) and lamivudine (LAM) reduces long-term recurrence rates below 10%; however, HBIG is costly and inconvenient to administer. We, therefore, conducted a multicenter, prospective study of outcomes with an HBIG-sparing regimen of LAM plus adefovir dipivoxil (ADV) initiated at the time of listing for liver transplantation and continued after transplantation. Twenty-six patients were recruited into this study at the time of listing for transplantation, and 20 subsequently underwent transplantation. Twelve of the 26 patients had LAM exposure before the study baseline, but none had LAM resistance. The median HBV viral load before the institution of antiviral therapy was approximately 4.0 log(10) IU/mL (range=2.3-7.5 log(10) IU/mL). To the 20 patients who underwent transplantation, 800 IU of intramuscular HBIG was given immediately after transplantation and daily for 7 days only (total HBIG dose=6400 IU). All transplant patients remained alive without HBV recurrence (they were negative for hepatitis B surface antigen, and HBV DNA was undetectable) after a median follow-up of 57 months after transplantation (range=27-83 months). The median serum creatinine level in these patients rose from 81 to 119 μmol/L over the course of the study. No patient required dose reduction or cessation. After the completion of this prospective study, the regimen was modified so that no perioperative HBIG was administered if the pretransplant serum HBV DNA level was suppressed below 3 log(10) IU/mL. Another 28 patients with HBV-related liver disease underwent transplantation (18 without HBIG). All remained alive and well without HBV recurrence after a median follow-up of 22 months after transplantation (range=10-58 months). In conclusion, a combination of LAM and ADV initiated at the time of wait listing provides safe and effective protection against recurrent HBV infection without the high costs and inconvenience associated with long-term HBIG therapy.

Abstract
Backgrounds/Aims Since most transplantation studies for alcoholic liver disease (ALD) were performed on deceased donor liver transplantation, little was known following living donor liver transplantation (LDLT). Methods The clinical outcome of 18 ALD patients who underwent LDLT from Febraury 1997 to December 2004 in a large-volume liver transplantation center was assessed retrospectively. Results The model for end-stage liver disease score was 23±11, and mean pretransplant abstinence period was 16±13 months, with 14 (77.8%) patients being abstinent for at least 6 months. Graft types were right lobe grafts in 11, left lobe grafts in 2 and dual grafts in 5. Graft to recipient body weight ratio was 0.94±0.16. The relapse rates in patients who did and did not maintain 6 months of abstinence were 7.1% and 50%, respectively (p=0.097). Younger recipient age was a significant risk factor for alcohol relapse (p=0.027). Five recipients with antibody to hepatitis B surface antigen (HBsAg) received core antibody-positive liver graft, but two of them showed positive HBsAg seroconversion. Overall 5-year patient survival rate following LDLT was 87.8%, with a 5-year relapse rate of 16.7%. Conclusions Pretransplant abstinence for 6 months appears to be benefical for preventing posttransplant relapse. Life-long prophylactic measure should be followed after use of anti-HBc-positive liver grafts regardless of hepatitis B viral marker status of the recipient.

The effect of pretransplantation lamivudine resistance on the prognosis of liver transplant recipients. Transplant Proc 2013; 45:231-5. [PMID: 23375306 DOI: 10.1016/j.transproceed.2012.06.078] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2012] [Accepted: 06/19/2012] [Indexed: 11/23/2022]
Abstract
BACKGROUND Since the introduction of lamivudine to treat chronic hepatitis B (CHB), the prevalence of lamivudine resistance is increasing among orthotopic liver transplant (OLT) candidates in Korea. OBJECTIVE The purpose of this study was to evaluate the effect of pre-OLT lamivudine-resistance on the post-OLT prognosis of recipients. MATERIAL AND METHODS Consecutive OLT recipient at a single tertiary care center (n = 8) between September 1999 and August 2009 were tested preoperatively for genotypic lamivudine resistance. We compared overall survival as well as incidences of graft failure, recurrent hepatitis, and hepatocellular carcinoma (HCC) between patients with (n = 35) versus without (n = 46) lamivudine-resistance. RESULTS Mortality occurred in 2 resistant and 3 nonresistant individuals. The occurrences of graft failure, recurrent hepatitis, and HCC were 1, 2, and 2 cases, respectively, in the resistance group versus 2, 2, and 2 cases, respectively, in the nonresistance cohort. Univariate analysis showed no significant difference in survival, graft failure, HCC occurrence, and recurrent hepatitis. CONCLUSIONS Our results indicated that pre-OLT lamivudine-resistance did not significantly affect the post-OLT prognosis. Thus, lamivudine-resistance may not be a barrier when considering OLT in patients with underlying CHB as a therapeutic modality, if it is treated with appropriate antiviral agents.

Abstract
Life-long hepatitis B immunoglobulin (HBIG) administration is a main component of prophylactic strategy to prevent hepatitis B virus (HBV) reinfection after liver transplantation (LT). Long-term effects of HBIG treatment are known only for intravenous (IV) and intramuscular formulations. To evaluate safety and efficacy of self-administered SC HBIG, 135 LT patients receiving a 48-week treatment were analyzed. The dose of HBIG was 500 IU or 1000 IU if body weight was <75 kg or ≥75 kg, respectively. Patients were switched from the monthly IV HBIG treatment to weekly SC HBIG 2-3 weeks after the last IV dosage. All patients were able to SC self-injection after a single training. The treatment was effective in maintaining trough anti-HBs levels >100 IU/L. No severe drug-related side effects occurred. Fifteen injection-site small hematomas and four cases of mild itch occurred. At the end of the study, anti-HBs median titer was 232 IU/L (115-566 IU/L) and 97.8% of patients had an anti-HBs level >150 IU/L. Due to high mean level of anti-HBs titers observed during this study, individualized treatment schedules should be further investigated. In conclusion, SC HBIG for long-term prophylaxis of post-LT HBV reinfection resulted safe, well accepted, and effective in maintaining adequate anti-HBs levels.

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
BACKGROUND A combination of hepatitis B immunoglobulin and nucleos(t)ide analogues is the current standard of care for controlling hepatitis B recurrence after orthotopic liver transplantation (OLT). However, frequent immunoglobulin treatment is expensive and inconvenient. This study investigated the efficacy of hepatitis B virus (HBV) vaccination in preventing the recurrence of hepatitis B after living donor OLT. METHODS Twenty-seven patients who had undergone living donor OLT participated in the study; five had acute HBV infected liver failure (ALF-OLT) and 22 had HBV related liver cirrhosis (LC-OLT). Hepatitis B surface antigen (HBsAg)-containing vaccine was administered to them for at least 1 year after transplantation and continued once monthly for up to 36 months post-OLT. Patients who had anti-HBs antibody titers above 100 mIU/mL for a minimum of 6 months without immunoglobulin administration were defined as good responders; the others were defined as poor responders. Interferon-γ enzyme-linked immunospot assays against HBs and HBc antigens were used to assay cellular immune responses. RESULTS All five of the ALF-OLT patients had good responses after a median of four (range 2.5-5) vaccinations. Nine of the 22 LC-OLT patients had good responses after a median of 19 (range 11.5-30) vaccinations. Among the LC-OLT group, those with livers donated by relatively higher-aged, marital and high-titer anti-HBs antibody donors were good responders. LC-OLT patients classed as good responders showed interferon-γ responses comparable to those of the ALF-OLT patients. CONCLUSIONS The ALF-OLT and LC-OLT patients who received livers from relatively higher-aged, marital, high-titer anti-HBs antibody donors were the best candidates for HBV vaccine administration. Boosting donors before transplantation may facilitate later vaccine response of the recipients.

Abstract
BACKGROUND Despite the advances in the treatment of chronic hepatitis B virus (HBV) infection, liver transplantation (LT) remains the only hope for many patients with end-stage liver diseases resulting from HBV. OBJECTIVES The aim of this study was to investigate the rate of HBV recurrence in cases that had undergone LT due to the HBV related liver cirrhosis. PATIENTS AND METHODS Forty-nine patients who underwent LT due to HBV related cirrhosis since 2001 to 2009 in Shiraz Organ Transplantation Center were enrolled in the present study. They were asked to complete the planned questionnaire and also to sign the informed consent in order to take part in this study. Post-transplant prophylaxis protocol against HBV recurrence was based on a hundred milligrams of lamivudine daily plus intramuscular injections of hepatitis B immune globulin (HBIG) with appropriate dosage to keep anti-HBs antibody titer above 300 IU/L and 100 IU/L in the first six months and afterwards, respectively. Blood samples were obtained and checked for HBsAg, HBeAg, and the titers of Anti -HBsAb as well as Anti- HBeAb with ELISA. A quantitative HBV DNA assay was also done on all samples (GENE-RAD® Real-time PCR). RESULTS There were 91.8% males and 8.2% females enrolled in the study. The duration of post-transplant prophylaxis ranged from 3 months to 8 years (mean 18.9 ± 19.3 months). HBsAg and HBeAg were positive in 24.5% and 2% of cases, respectively. Real-time PCR for HBV DNA were zero copies/mL in 91.8% of patients, none of which represented a positive value for HBV recurrence (Positive > 10,000 copies/mL). The mean Anti-HBs Ab titer was 231.7 ± 135.9 IU/L; it was above 100 IU/L in 71.4% of patients. Thirty-seven (75.5%) of the patients were taking tacrolimus plus mycophenolate mofetil, 6 (12.2%) were on cyclosporine plus mycophenolate mofetil, and 6 (12.2%) were taking sirolimus plus mycophenolate mofetil. HBsAg was detectable in seven patients taking tacrolimus plus mycophenolate mofetil (18.9%), in four patients taking cyclosporine plus mycophenolate mofetil (66.7%), and in one patient among the six who were taking sirolimus plus mycophenolate mofetil (16.7%). There was no significant statistical correlation between the presence of a positive value for HBsAg and the immunosuppression regimen or Anti HBsAb titer (P ˃ 0.05). Presence of a positive value for HBsAg was not predictive of a positive HBV DNA or its level in blood (P ˃ 0.05). CONCLUSIONS Post-transplant HBV prophylaxis with lamivudine and intramuscular HBIG with appropriate dosage to keep anti-HBs antibody titer above 300 IU/L in the first six months and above 100 IU/L afterwards is effective for prevention of HBV recurrence after LT.

Abstract
Liver transplantation is indicated in patients with acute liver failure, decompensated cirrhosis, hepatocellular carcinoma and rare liver-based genetic defects that trigger damage of other organs. Early referral to a transplant center is crucial in acute liver failure due to the high mortality with medical therapy and its unpredictable evolution. Referral to a transplant center should be considered when at least one complication of cirrhosis occurs during its natural history. However, because of the shortage of organ donors and the short-term mortality after liver transplantation on one hand and the possibility of managing the complications of cirrhosis with other treatments on the other, patients are carefully selected by the transplant center to ensure that transplantation is indicated and that there are no medical, surgical and psychological contraindications. Patients approved for transplantation are placed on the transplant waiting list and prioritized according to disease severity. Thus, the appropriate timing of transplantation depends on recipient disease severity and, although this is still a matter of debate, also on donor quality. These two variables are known to determine the “transplant benefit” (i.e., when the expected patient survival is better with, than without, transplantation) and should guide donor allocation.

Abstract
UNLABELLED The guideline on the management of chronic hepatitis B (CHB) was first developed in 2004 and revised in 2007 by the Korean Association for the Study of the Liver (KASL). Since then there have been many developments, including the introduction of new antiviral agents and the publications of many novel research results from both Korea and other countries. In particular, a large amount of knowledge on antiviral resistance--which is a serious issue in Korea--has accumulated, which has led to new strategies being suggested. This prompted the new guideline discussed herein to be developed based on recent evidence and expert opinion. TARGET POPULATION The main targets of this guideline comprise patients who are newly diagnosed with CHB and those who are followed or treated for known CHB. This guideline is also intended to provide guidance for the management of patients under the following special circumstances: malignancy, transplantation, dialysis, coinfection with other viruses, pregnancy, and children.

Abstract
Liver transplantation is the only alternative for patients with end-stage liver disease. Viral hepatitis B and C are among the most common causes of cirrhosis and hepatocellular carcinoma and a frequent indication for liver transplantation. Hepatitis B virus immunoglobulin and nucleot(s)ide analogues have facilitated the management of patients with hepatitis B who have received liver transplants and resulted in excellent long-term outcomes. On the contrary, recurrence of hepatitis C is the main cause of graft loss in most transplant programs. Current therapeutic approaches are far from optimal, because sustained virologic responses are only achieved in one-third of treated patients, and adverse effects are common and severe. However, the rapid development of direct-acting antivirals against hepatitis C virus will change the management of this disease and in a few years prevent graft infection with this virus.

Abstract
Since the early 1990's, hepatitis B immune globulin (HBIG) has been central to the prevention of hepatitis B virus (HBV) recurrence after liver transplantation. When used in combination with oral nucleos(t)ide analogues, HBIG prevents reinfection with HBV in ⩾90% of transplant recipients. While HBIG is highly efficacious, its use is undermined by its high cost. Because of this limitation, there have been many studies of alternative regimens seeking to minimize the dose or duration of HBIG without sacrificing low HBV recurrence rates. Toward that goal, lower dose intramuscular HBIG in combination with oral nucleos(t)ide analogues has been shown to be highly efficacious in preventing disease recurrence and represents a significant cost savings when compared with high dose intravenous administration. The withdrawal of HBIG after a defined course of combination HBIG and oral antivirals has also been shown to be effective, particularly if combination antiviral therapy is used. The ability to achieve undetectable HBV DNA levels pre-transplantation in the majority of patients may contribute to the high efficacy of these HBIG "light" regimens. Additionally, the success of antiviral rescue therapy for those patients who fail prophylaxis and develop recurrent HBV infection post-transplant has provided the impetus to move increasingly towards HBIG-free approaches. New techniques to detect occult HBV in hepatic and extrahepatic sites may allow clinicians to define a subgroup of patients in whom withdrawal of HBIG or all prophylaxis may be applicable.

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
Hepatitis B virus (HBV) associated end-stage liver diseases are the leading causes of liver transplantation (LT) in Taiwan. Relapse of hepatitis B occurs after LT, raising the risk of graft failure and reducing patient survival. Although several oral antiviral agents have been approved for anti-HBV treatment, lamivudine (LAM) remained to be the most widely used preventive regimen in Taiwan. While several clinical predictors have been identified for hepatitis B relapse, the predictive roles of the histopathological characteristics in liver explants as well as the genotypic features of the viruses in pre-LT serum samples have not been assessed. Between September 2002 and August 2009, 150 consecutive hepatitis B surface antigen (HBsAg) positive patients undergoing LT were included for outcome analysis following assessment of the clinicopathological and virological factors prior to LT. Kaplan-Meier analyses discovered that pre-operative LAM treatment ≤3 months; membranous distribution and higher expression of tissue HBsAg in liver explants; preoperative viral load ≧106 copies/ml; and presence of large fragment (>100 base pairs) pre-S deletion (LFpreSDel) correlated significantly with hepatitis B relapse. Multivariate Cox regression analysis showed that the presence of LFpreSDel (P = 0.001) and viral load ≧106 copies/mL (P = 0.023) were independent predictors for hepatitis B relapse. In conclusion, besides high viral load, LFpreSDel mutation is an important independent predictor for hepatitis B relapse after LT. More aggressive preventive strategies should be applied for patients carrying these risk factors.

Abstract
Management of viral infections after transplantation involves antiviral drug therapy (if available) and reduction in immunosuppression, which allows for development of pathogen-specific immunity to the offending virus. Prevention of viral infections is of the utmost importance, and this may be accomplished through vaccination, antiviral strategies and infection control measures. This article discusses the current management of selected viral pathogens that cause clinical illness in solid organ transplant recipients. The benefits and toxicities of antiviral therapies are discussed in the context of prevention and treatment of various viral diseases. The emerging issue of antiviral resistance is emphasized for cytomegalovirus, recurrent hepatitis B and influenza, while the importance of immunominimization is discussed in the management of BK nephropathy and virus-associated malignancies.

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
Intravenous hepatitis B immunoglobulin (HBIG) is a human plasma-derived purified gammaglobulin (IgG) that has proven efficacy and dose-dependent response in the prevention of hepatitis B virus (HBV) recurrence after liver transplantation. It is also indicated for postexposure prophylaxis after contact with blood or body fluids of serum hepatitis B surface antigen (HBsAg)-positive carriers and in prevention of mother-to-child (vertical) transmission. The exact mechanism of passive immunization is unknown; HBIG may block HBV entry and binding to hepatocytes, neutralize circulating HBV and target HBV-infected cells through an antibody-mediated immune response. The drug is well tolerated and common side effects include fever, chills and arthralgias that are usually mild and transient. This article summarizes the main indications and the recommendations for use of intravenous HBIG, as well as the usage of intramuscular HBIG in the liver transplant setting.

Abstract
The management of hepatitis B in liver transplantation has evolved significantly over the past 2 decades. Introduction of hepatitis B immune globulin and subsequently nucleos(t)ide analogues has revolutionized transplantation for hepatitis B virus (HBV), increasing survival for patients transplanted for this indication. With the availability of new and potent antivirals for HBV, the need for liver transplant should continue to decrease in the coming years. Moreover, the newer antivirals with high resistance barriers will allow effective long-term viral prophylaxis and therefore, prevention of recurrence.

Abstract
Passive immunization employs preformed antibodies provided to an individual that can prevent or treat infectious diseases. There are several situations in which passive immunization can be used: for persons with congenital or acquired immunodeficiency, prophylactic administration when there is a likelihood of exposure to a particular infection, or treatment of a disease state already acquired by the individual. Passive immunization is limited by short duration (typically weeks to months), variable response, and adverse reactions. This article focuses on specific immunoglobulins for preventing or treating infectious diseases, as these are the most likely scenarios one might encounter in primary care practice.

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.
