Novel protocol for prevention from hepatitis B reactivation following living-donor liver transplantation. Hepatol Res 2024.

Abstract
AIM Reactivation of hepatitis B virus (HBV) after liver transplantation (LT) remains a problem; thus, development of more effective HBV reactivation prophylaxis is desirable. We evaluated the efficacy of a combination of a long-term nucleotide analog (NA), such as entecavir (ETV) or tenofovir alafenamide (TAF), and short-term hepatitis B immunoglobulin (HBIG) in preventing HBV reactivation and compared it with conventional HBV prophylaxis. METHODS Between February 1999 and August 2023, 135 patients underwent living-donor liver transplantation for liver cirrhosis or acute liver failure caused by HBV infection or received an LT from a hepatitis B core antibody-positive donor. Recipients who had undergone LT were classified as being in the first or second era (namely until September 2017 and from October 2017), respectively, and outcomes of prophylaxis against HBV reactivation were compared between the two eras. RESULTS In the second era, recipients with HBV-related disease or who had received hepatitis B core antibody-positive liver received combination therapy with short-term HBIG and an NA such as TAF and ETV long-term. The duration of HBIG treatment was markedly shorter than in the first era in both categories of patients and HBIG could be discontinued in all cases. Surprisingly, we observed HBV reactivation in the first era, but not in the second era, in both groups. CONCLUSIONS We have established a protocol for prophylaxis against HBV reactivation using a combination of short-term HBIG and long-term NA. This protocol was found to be sufficient to prevent HBV reactivation after LT.

Abstract
Hepatitis is a significant global public health concern, with viral infections being the most common cause of liver inflammation. Antiviral medications are the primary treatments used to suppress the virus and prevent liver damage. However, the high cost of these drugs and the lack of awareness and stigma surrounding the disease create challenges in managing hepatitis. Stem cell therapy has arisen as a promising therapeutic strategy for hepatitis by virtue of its regenerative and immunomodulatory characteristics. Stem cells have the exceptional capacity to develop into numerous cell types and facilitate tissue regeneration, rendering them a highly promising therapeutic avenue for hepatitis. In animal models, stem cell therapy has demonstrated worthy results by reducing liver inflammation and improving liver function. Furthermore, clinical trials have been undertaken to assess the safety and effectiveness of stem cell therapy in individuals with hepatitis. This review aims to explore the involvement of stem cells in treating hepatitis and highlight the findings from studies conducted on both animals and humans. The objective of this review is to primarily concentrate on the ongoing and future clinical trials that assess the application of stem cell therapy in the context of hepatitis, including the transplantation of autologous bone marrow-derived stem cells, human induced pluripotent stem cells, and other mesenchymal stem cells. In addition, this review will explore the potential merits and constraints linked to stem cell therapy for hepatitis, as well as its prospective implications in the management of this disease.

Viruses 2023; 15:v15051037. [PMID: 37243124 DOI: 10.3390/v15051037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2023] [Revised: 04/15/2023] [Accepted: 04/21/2023] [Indexed: 05/28/2023] Open
Abstract
Hepatitis B virus (HBV) is a prevalent underlying disease, leading to liver transplantation (LT) for both decompensated cirrhosis and hepatocellular carcinoma (HCC). The hepatitis delta virus (HDV) affects approximately 5-10% of HBsAg carriers, accelerating the progression of liver injury and HCC. The initial introduction of HBV immunoglobulins (HBIG), and then of nucleos(t)ide analogues (NUCs), considerably improved the survival of HBV/HDV patients post-transplantation, as they helped prevent re-infection of the graft and recurrence of liver disease. Combination therapy with HBIG and NUCs is the primary post-transplant prophylaxis strategy in patients transplanted for HBV- and HDV-related liver disease. However, monotherapy with high-barrier NUCs, such as entecavir and tenofovir, is safe and also effective in some individuals who are at low risk of HBV reactivation. To address the problems of organ shortage, last-generation NUCs have facilitated the use of anti-HBc and HBsAg-positive grafts to meet the ever-increasing demand for grafts.

Abstract
BACKGROUND AND AIMS Tenofovir disoproxil fumarate (TDF) and entecavir (ETV) have been recommended after liver transplantation to prevent recurrence of hepatitis B virus infection. Despite its proven efficacy, the renal safety of TDF has not been established in liver transplant recipients. We aimed to compare the effects of TDF and ETV on renal function in liver transplant recipients and to evaluate risk factors for renal dysfunction after liver transplantation. METHODS This is a retrospective, observational multicenter study of data from the Korean Organ Transplantation Registry. We included adults who underwent liver transplantation for hepatitis B virus-related complications from April 2014 to December 2017 and received TDF or ETV post-transplantation. Renal dysfunction was defined as an estimated glomerular filtration rate decline by at least 20% from baseline (1 month post-transplantation). Median duration of follow-up was 29 months (interquartile range 19-42). RESULTS A total of 804 liver transplant patients were included. The cumulative probability of renal dysfunction was significantly higher in the TDF group than in the ETV group. Multivariable analysis confirmed that TDF was independently associated with an increased risk of renal dysfunction (hazard ratio = 1.47, 95% confidence interval 1.12-1.92; p = 0.005). Independent risk factors for renal dysfunction included older age, worse baseline renal function, and low body mass index. Overall survival rate was significantly lower in patients with renal dysfunction than in those without. CONCLUSIONS In this nationwide study, the use of TDF was associated with an increased risk of renal dysfunction, when compared with ETV.

Abstract
Objective Hepatitis B virus (HBV) reinfection is a serious complication that arise in patients who undergo hepatitis B virus related liver transplantation. We aimed to use biomarkers to evaluate the HBV reinfection in patients after orthotopic liver transplantation. Methods Seventy-nine patients who underwent liver transplantation between 2009 and 2015 were enrolled, and levels of biomarkers were analyzed at different time points. Cox regression and receiver operating characteristic (ROC) curves of different markers at baseline were used to analyze sustained hepatitis B surface antigen (HBsAg) loss. The Kaplan-Meier method was used to compare the levels of the biomarkers. Results Among the 79 patients, 42 sustained HBsAg loss with a median time of 65.2 months (12.0-114.5, IQR 19.5) after liver transplantation and 37 patients exhibited HBsAg recurrence with a median time of 8.8 (0.47-59.53, IQR 19.47) months. In the ROC curve analysis, at baseline, 4.25 log10 IU/mL qHBcAb and 2.82 log10 IU/mL qHBsAg showed the maximum Youden’s index values with area under the curves (AUCs) of 0.685and 0.651, respectively. The Kaplan-Meier method indicated that qHBsAg and quantitative antibody against hepatitis B core antigen (qHBcAb) levels in the two groups were significantly different (p = 0.031 and 0.006, respectively). Furthermore, the Cox regression model confirmed the predictive ability of qHBcAb at baseline (AUC = 0.685). Conclusion Lower pretransplantation qHBcAb is associated with HBV infection. The baseline concentration of qHBcAb is a promising predictor for the recurrence of HBV in patients undergoing liver transplantation and can be used to guide antiviral treatment for HBV infection.

Abstract
The factors associated with hepatitis B virus (HBV) recurrence after living donor liver transplantation (LDLT) have not been fully clarified. The aim of this study was to determine the risk factors associated with HBV recurrence after LDLT. From January 1996 to December 2018, a total of 609 LDLT operations were performed at our center. A retrospective review was performed of 70 patients (male, n = 59; female, n = 11; median age = 54 years) who underwent LDLT for HBV-related liver disease. The virologic and biochemical data, tumor burden, antiviral and immunosuppressive therapy were evaluated and compared between the HBV recurrence and non-recurrence groups. Eleven of 70 patients (16%) developed post-LDLT HBV recurrence. The overall actuarial rates of HBV recurrence at 1, 3, 5, 10, and 20 years were 0%, 13%, 16.7%, 18.8%, and 18.8%, respectively. The median interval between LDLT and HBV recurrence was 57 months (range, 18-124 months). Based on the univariate and multivariate analyses, a serum HBV DNA level of ≥ 4 log copies/mL (hazard ratio [HR], 4.861; 95% confidence interval [95% CI], 1.172-20.165; P = 0.029), and hepatocellular carcinoma (HCC) beyond the Milan criteria (HR, 10.083; 95% CI, 2.749-36.982; P < 0.001) were independent risk factors for HBV recurrence after LDLT. In LDLT patients, high pre-LT HBV DNA levels and HCC beyond the Milan criteria were risk factors for HBV recurrence. With the current expansion of the LT criteria for HCC, we should remain cautious regarding the risk of HBV recurrence, particularly in these groups.

Abstract
Potent nucleos(t)ide analogues and hepatitis B immunoglobulin combinations are recommended after liver transplantation to prevent the recurrence of hepatitis B virus (HBV). Despite its proven efficacy, the renal safety of tenofovir disoproxil fumarate (TDF) has not been well established in liver transplant recipients. We aimed to assess the impacts of TDF and entecavir (ETV) on tubular and glomerular functions. We analysed 206 liver transplant patients treated with TDF (n = 102) or ETV (n = 104) plus hepatitis B immunoglobulin. Serum creatinine, phosphate and uric acid levels were measured. Proximal tubular dysfunction was defined as the presence of hypophosphatemia (<2 mg/dL) and hypouricemia (<2 mg/dL). Glomerular dysfunction was defined as an estimated glomerular filtration rate (eGFR) of <60 mL/min/1.73 m2 accompanied by a ≥25% eGFR decline from baseline. During a median follow-up of 42.5 months, 48 patients developed proximal tubular dysfunction (30.4% and 16.3% in the TDF and ETV groups; P = .017). Serum levels of phosphate and uric acid were significantly lower in the TDF group post-LT. TDF (OR, 2.34; 95% CI, 1.16-4.69; P = .017) and low body mass index (OR, 2.11; 95% CI, 1.06-4.21; P = .034) were independent risk factors for proximal tubular dysfunction. The prevalence of glomerular dysfunction was not significantly different between the two groups (TDF 51.0% and ETV 54.8%; P = .582). TDF significantly increased the risk of proximal tubular dysfunction. Although the effect of TDF on glomerular function was comparable to that of ETV, glomerular dysfunction was common after liver transplant.

Transpl Infect Dis 2020; 22:e13303. [PMID: 32367631 DOI: 10.1111/tid.13303] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2020] [Revised: 03/16/2020] [Accepted: 04/25/2020] [Indexed: 02/06/2023]
Abstract
BACKGROUND Hepatitis B immunoglobulin (HBIG)-as a monotherapy or combined with nucleos(t)ide analogs (NUCs)-has effectively lowered Hepatitis B virus (HBV) reinfection after liver transplantation. However, it is associated with high costs and viral resistance. HBIG-free prophylaxis with novel NUCs (tenofovir, entecavir) composes a viable alternative. We evaluated reinfection rate, histological changes, and outcome associated with HBIG discontinuation. METHODS A retrospective analysis was performed of patients undergoing liver transplantation due to HBV-induced liver disease at our center since 1988. A controlled HBIG discontinuation was conducted between 2015 and 2017 in 65 patients. Recurrent infection was determined by HbsAg values. Fibrosis and inflammation were evaluated by routine biopsy. The survival of patients after HBIG discontinuation was compared to a control population on HBIG for prophylaxis. RESULTS From 1988 to 2013, 352 patients underwent liver transplantation due to HBV-induced liver disease. 169 patients could be included for analysis. 104 (51.5%) patients continued a prophylaxis containing HBIG. HBIG was discontinued in 65 (38.5%) patients in a controlled manner, maintaining an oral NUC. None of those patients showed HBV reinfection or graft dysfunction. No significant changes of inflammation grades (P = .067) or fibrosis stages (P = .051) were detected. The survival of patients after HBIG discontinuation was comparable to the control (P = .95). CONCLUSION HBIG withdrawal under continuation of oral NUC therapy is safe and not related to graft dysfunction, based on blood tests and histology. HBIG-free prophylaxis is not associated with a worse outcome and displays a financial relief as well as a logistic simplification during long-term follow-up.

Abstract
Background/aim In this study, the efficiency of using low-dose hepatitis B immunoglobulin (HBIG) plus antiviral treatment according to individual needs has been evaluated in posttransplant hepatitis B virus (HBV) patients. Materials and methods We retrospectively evaluated 179 patients who were admitted between 2009 and 2014. Five thousand IU intravenous HBIG was given in the anhepatic phase, and 400 IU/day intramuscular (IM) HBIG was given in the posttransplant period. After HBsAg seroconversion, 400 IU IM HBIG was continued as prophylaxis every two weeks. Results The average follow-up period was 26 (2–65) months. Seventy patients had hepatocellular carcinoma (HCC). The HBV recurrence was 4.5% in the first year, and 5.8% in the third year. The HBsAg became negative in 11 (2–63) days, and anti-HBs became positive in 9 (1–31) days. HBsAg positivity occurred in 6 patients during the follow-up period. Five of these patients were those who underwent transplantation due to HCC. In 5 of the HCC patients, in whom HBsAg became positive, tumor recurrence was observed after 0.3–9.9 months. HBsAg positivity was more frequently detected in patients with HCC (P = 0.009). Conclusion The HBV recurrence should be evaluated as a predictor of the HCC recurrence in patients who were transplanted due to HCC.

Abstract
Aims: To determine efficacy and safety of intravenous hepatitis B immune globulin (Niuliva®, Grifols) to prevent reinfection in de novo orthotopic liver transplantation. Patients & methods: In a nonrandomized, noncontrolled and Phase III clinical trial, 15 adult patients (12 men) were treated with Niuliva from the anhepatic phase (10,000 IU/daily 1 week postsurgery) up to 6 or 12 months (5000 IU/weekly 1 month; 5000 IU/monthly thereafter). Results: No patients showed reinfection throughout the study. Niuliva was effective in maintaining antibody titers above the thresholds recommended by the European Medicines Agency (EMA) to prevent reinfection (100–150 IU/l). Four serious adverse events were reported in three patients (none related to the study product). There were no seroconversions and no deaths. Conclusion: Long-term, high-dose Niuliva administration was safe and effective to prevent graft reinfection in the tested patients.

Abstract
This chapter describes the principles of antiviral therapy, treatment strategies, medications and recommendations for AECHB, HBV-ACLF, HBV-related liver cirrhosis, HBV-related HCC, and liver transplantation.Severe exacerbation of chronic hepatitis B is closely related to continuous HBV replication. Therefore, inhibiting HBV replication to reduce viral load may block disease progression and improve the quality of life of these patients. ETV or TDF has been recommend first-line drug for the treatment of AECHB. A hyperactive immune response due to continuous HBV replication is the main mechanism for development of severe hepatitis B. In addition to comprehensive treatment, early administration of potent nucleoside analogs can rapidly reduce HBV DNA concentration, relieve immune injury induced by HBV, and reduce liver inflammation and patient mortality. Antiviral agents have become important in the treatment of severe exacerbation of chronic hepatitis B. Long-term antiviral treatment with nucleoside analogs can delay or reverse the progress of liver cirrhosis. Virologic response, viral resistance and adverse drug reactions should be closely monitored during treatment. The treatment should be optimized for maximum effect based on each patient’s responses. Effective antiviral therapy can suppress HBV replication and reduce the incidence of HBV-related HCC. Patients with HBV-related HCC should receive individualized and optimal multidisciplinary comprehensive treatment. Anti-viral drugs with high efficacy, low resistance and low adverse drug reactions should be selected to improve the patient’s quality of life and prolong survival time. Methods to prevent HBV reinfection after liver transplantation include passive immunization (HBIG), antiviral treatment (nucleoside analogs) and active immunization (hepatitis B vaccine). Clinical trials involving sequential combination therapy with NUC and Peg-IFN have shown statistically significant decline in HBsAg levels on treatment and high rates of sustained post-treatment serologic response. Combination therapy with novel DAA and immunotherapeutic approach may hold promise to overcome both cccDNA persistence and immune escape, representing a critical step towards HBV cure.

Abstract
BACKGROUND Hepatitis B (HBV)-associated end-stage liver disease used to be a relevant indication for liver transplantation (LT). After transplantation, HBV-reinfection remains a serious issue. Different strategies to prevent HBV-reinfection range from the single application of immunoglobulins (HBIG), to the use of modern nucleoside/nucleotide analogues (NUC) in combination with HBIG, followed by HBIG-discontinuation. The aim of this analysis was to compare different strategies and to sum up the results of 30 years at a high-volume transplant center and deliver additional information on the histopathological level. METHODS Data of 372 liver transplantations performed for the HBV-induced liver disease in 352 patients were extracted from a prospectively organized database. HBV-reinfection was determined in the entire cohort, according to the mode of HBV-prophylaxis. Differences in survival rates were analyzed in patients with successful prophylaxis, untreated and controlled HBV-reinfection. Histopathological results were obtained from protocol biopsies in 151 patients. RESULTS HBV-reinfection was significantly associated with the type of prophylaxis, presence of HBs-Antigen at the moment of LT, transplant year and influencing the overall survival before 2005. After the introduction of modern NUCs, HBV-reinfection stopped to impact HBV-associated transplant loss and survival. Controlled HBV-infection prevents from HBV-associated transplant hepatitis and fibrosis development. The role of HBIG declines in favor of NUCs. CONCLUSIONS Uncontrolled HBV-reinfection does not occur any more. Even in the presence of Hbs-antigen, transplant fibrosis does not develop. The most reliable mode to prevent HBV-recurrence remains the combination of NUCs with a high genetic barrier and HBIG. However, HBIG can safely be discontinued after LT.

Abstract
BACKGROUND The Amazon region is one of the main endemic areas of hepatitis delta in the world and the only one related to the presence of genotype 3 of the delta virus. OBJECTIVE To analyze the profile, mortality and survival of cirrhotic patients submitted to liver transplantation for chronic hepatitis delta virus and compare with those transplanted by hepatitis B virus monoinfection. METHODS Retrospective, observational and descriptive study. From May 2002 to December 2011, 629 liver transplants were performed at the Walter Cantídio University Hospital, of which 29 patients were transplanted due to cirrhosis caused by chronic delta virus infection and 40 by hepatitis B chronic monoinfection. The variables analyzed were: age, sex, MELD score, Child-Pugh score, upper gastrointestinal bleeding and hepatocellular carcinoma occurrence before the transplantation, perioperative platelet count, mortality and survival. RESULTS The Delta Group was younger and all came from the Brazilian Amazon Region. Group B presented a higher proportion of male patients (92.5%) compared to Group D (58.6%). The occurrence of upper gastrointestinal bleeding before transplantation, MELD score, and Child-Pugh score did not show statistical differences between groups. The occurrence of hepatocellular carcinoma and mortality were higher in the hepatitis B Group. The survival in 4 years was 95% in the Delta Group and 75% in the B Group, with a statistically significant difference (P=0.034). Patients with hepatitis delta presented more evident thrombocytopenia in the pre-transplantation and in the immediate postoperative period. CONCLUSION The hepatitis by delta virus patients who underwent liver transplantation were predominantly male, coming from the Brazilian Amazon region and with similar liver function to the hepatitis B virus patients. They had a lower incidence of hepatocellular carcinoma, more marked perioperative thrombocytopenia levels and frequent episodes of upper gastrointestinal bleeding. Patients with hepatitis by delta virus had lower mortality and higher survival than patients with hepatitis B virus.

Abstract
BACKGROUND Post-transplant hepatitis B virus (HBV) reinfection is one of the major problems facing patients who undergo HBV-related liver transplantation (LT). We analyzed the clinical impact of serum hepatitis B core-related antigen (HBcrAg) on HBV reinfection in post-LT patients with HBV-related liver diseases. METHODS Serum hepatitis B surface antigen (HBsAg), HBV DNA, and HBcrAg were measured over time in 32 post-LT patients. Twenty-one out of 32 patients had HCC at LT. The effects of HBcrAg, hepatocellular carcinoma (HCC) recurrence, and HBs gene mutation on HBV reinfection and withdrawal from hepatitis B immune globulin (HBIG) were analyzed. RESULTS Sixteen out of 32 patients (50 %) were positive for HBcrAg even though only six patients were thought to have experienced HBV reinfection based on reappearance of either HBV DNA or HBsAg during a median follow-up time of 75 months. Three of these six patients who became re-infected with HBV experienced HCC recurrence after LT. The HBV DNA reappearance rate was significantly higher in patients with HCC recurrence after LT (p < 0.001). Two HBV re-infected patients without HCC recurrence had HBs gene mutations G145R and G145A, respectively. Anti-HBs antibody development rate by HB vaccination was similar between HBcrAg-positive and negative patients (p = 0.325). CONCLUSIONS HBV reinfection is more common than is usually considered based on conventional measurement of HBsAg and HBV DNA. HCC recurrence and mutations in the HBV S gene were associated with HBV reinfection after LT.

Abstract
To investigate the levels of hepatitis B virus total DNA (HBV DNA) and covalently closed circular (ccc) DNA in liver transplant recipients who received hepatitis B vaccination, including responders and non-responders, following liver transplantation due to hepatitis B-related diseases and to investigate the efficacy of hepatitis B immune reconstitution against HBV reinfection. Twenty responders and 34 non-responders were enrolled in the present study. The levels of HBV total DNA and ccc DNA in peripheral blood mononuclear cells (PBMCs) and the liver and plasma were detected by real-time polymerase chain reaction (PCR). Fifty-three blood samples and 38 liver allograft tissues were acquired. For the responders, the mean serum titer for anti-HBs (antibodies against hepatitis B surface antigen) was 289 (46.64-1000) IU/ml. Also for the responders, HBV total DNA was detected in PBMCs for one recipient and in the liver for another recipient, but ccc DNA was not detected in either of those 2 recipients. For the non-responders, HBV total DNA was detected in PBMCS for 2 recipients, neither of whom had ccc DNA. Also for the non-responders, HBV total DNA was detected in the livers of 3 recipients, 2 of whom also had ccc DNA. All responders had discontinued hepatitis B immunoglobulin (HBIG), and 13 responders had discontinued antiviral agents. One responder experienced HBV recurrence during the follow-up period. For the majority of liver transplant recipients, no HBV total DNA or ccc DNA was detected in the blood or liver. The lack of HBV total DNA and ccc DNA both in PBMCs and the liver in liver transplant recipients who received hepatitis B vaccination to prevent HBV reinfection should be a prerequisite for the withdrawal of HBIG and/or antiviral agents.

Treat chronic hepatitis C virus infection in decompensated cirrhosis - pre- or post-liver transplantation? the ironic conundrum in the era of effective and well-tolerated therapy. J Viral Hepat 2016; 23:408-18. [PMID: 27018088 DOI: 10.1111/jvh.12534] [Citation(s) in RCA: 53] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/24/2016] [Accepted: 03/01/2016] [Indexed: 12/12/2022]
Abstract
The management of hepatitis C virus (HCV) infection in patients with decompensated cirrhosis has evolved dramatically over the past few years mainly due to the availability of all-oral antiviral regimens. The currently approved all-oral direct-acting antivirals (DAA) containing sofosbuvir, ledipasvir, daclatasvir and ribavirin, in various combinations, have shown to be safe and effective in patients with decompensated cirrhosis with sustained virological response (SVR) rates nearly comparable to those with well-compensated liver disease. Unique issues yet remain such as the challenges with renal insufficiency, tolerability of ribavirin and risk of further hepatic decompensation with a protease inhibitor-based regimen. While most patients who achieve SVR have demonstrated improvement in hepatic synthetic function over the short course of follow, the long-term beneficial effects are unknown. Further, the baseline predictors of improvement in hepatic function have not been well delineated and thus have left us in a quandary as to what we might expect with successful therapy and thus we are at a loss to well educate our patients. The major concern, in potential liver transplant candidates, is of unintended 'harm' by achieving SVR but without improvement in hepatic function to an extent where the patients might function well. As HCV therapies are as effective in liver transplant recipients, there is a growing sentiment in some of the transplant quarters that those with decompensated liver disease and awaiting liver transplant be treated for HCV after liver transplant. This strategy would thus eliminate any concern of leaving a patient in 'no person's' land by treating HCV successfully pretransplant but not to the point of functional normalcy, while also would maintain the risk of HCC. Yet a contrarian view would be that not all patients have access to liver transplantation (LT), cannot bear the cost, have comorbidities or contraindications to LT. While the debate continues, it is essential that we develop robust predictors of improvement in liver function so that we can carefully select our patients for therapy in the context of liver transplantation.

Abstract
PURPOSE We sought to identify factors associated with increased resource utilization and in-hospital mortality for pediatric liver transplantation (LT). METHODS Kids' Inpatient Database (1997-2009) was used to identify cases of LT in patients <20 years old. RESULTS Overall, 2905 cases were identified, with an in-hospital survival of 91 %. LT was performed most frequently in < 5 year olds (61 %), females (51 %), and Caucasians (56 %). LT was performed at urban teaching hospitals (97 %) and facilities with children's units (51 %). Indications included pathologic conditions of the biliary tract (44 %) and inborn errors of metabolism (34 %), though unspecified end stage liver disease was the most common (75 %). Logistic regression found higher mortality in children undergoing LT for malignant conditions (odds ratio: 4.8) and acute hepatic failure (OR 3.4). Cases complicated by renal failure (OR 7.7) and complications of LT (OR 2.7) had higher mortality rates. Resource utilization increased for children with renal failure and those with hemorrhage as a complication of LT, p < 0.05. CONCLUSION Hospital survival is predicted by indication and complications associated with LT. Resource utilization increased with renal failure and complications related to LT. Admission length was sensitive to payer status, hospital characteristics, and UNOS region, whereas total costs were unaffected by payer status or hospital type.

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.

High-dose hepatitis B immunoglobulin therapy in hepatocellular carcinoma with hepatitis B virus-DNA/hepatitis B e antigen-positive patients after living donor liver transplantation. World J Gastroenterol 2016; 22:3803-3812.

Abstract
AIM: To investigate the impact of high-dose hepatitis B immunoglobulin (HBIG) on hepatocellular carcinoma (HCC) and hepatitis B virus (HBV) recurrence and overall survival after living donor liver transplantation (LDLT).
METHODS: We investigated 168 patients who underwent LDLT due to HCC, and who were HBV-DNA/hepatitis B e antigen (HBeAg) -positive, from January 2008 to December 2013. After assessing whether the patients met the Milan criteria, they were assigned to the low-dose HBIG group and high-dose HBIG group. Using the propensity score 1:1 matching method, 38 and 18 pairs were defined as adhering to and not adhering to the Milan criteria. For each pair, HCC recurrence, HBV recurrence and overall survival were analyzed by the Kaplan-Meier method and the log rank test according to the HBIG dose.
RESULTS: Among those who met the Milan criteria, the 6-mo, 1-year, and 3-year HCC recurrence-free survival rates were 88.9%, 83.2%, and 83.2% in the low-dose HBIG group and 97.2%, 97.2%, and 97.2% in the high-dose HBIG group, respectively (P = 0.042). In contrast, among those who did not meet the Milan criteria, HCC recurrence did not differ according to the HBIG dose (P = 0.937). Moreover, HBV recurrence and overall survival did not differ according to the HBIG dose among those who met (P = 0.317 and 0.190, respectively) and did not meet (P = 0.350 and 0.987, respectively) the Milan criteria.
CONCLUSION: High-dose HBIG therapy can reduce HCC recurrence in HBV-DNA/HBeAg-positive patients after LDLT.

Abstract
Chronic hepatitis B is a global health problem that leads to development of various complications, such as cirrhosis, liver cancer, and liver failure requiring liver transplantation. The recurrence of hepatitis B virus (HBV) post-liver transplantation is a major cause of allograft dysfunction, cirrhosis of the allograft, and graft failure. Patients with high viral load at the time of transplantation, hepatitis B e antigen (HBeAg) positivity, or those with a history of anti-viral drug resistance are considered as high-risk for recurrent HBV post-liver transplantation, while patients with low viral load, including HBeAg negative status, acute liver failure, and hepatitis D virus (HDV) co-infection are considered to be at low-risk for recurrent HBV post-liver transplantation. Antivirals for patients awaiting liver transplantation(LT) cause suppression of HBV replication and reduce the risk of recurrent HBV infection of the allograft and, therefore, all HBV patients with decompensated cirrhosis should be treated with potent antivirals with high genetic barrier to resistance (entecavir or tenofovir) prior to liver transplantation. Prevention of post-liver transplantation recurrence should be done using a combination of hepatitis B immunoglobulin (HBIG) and antivirals in patients at high risk of recurrence. Low dose HBIG, HBIG-free protocols, and monoprophylaxis with high potency antivirals can still be considered in patients at low risk of recurrence. Even, marginal grafts from anti-HBc positive donors can be safely used in hepatitis B surface antigen (HBsAg) negative, preferably in anti-hepatitis B core (HBc)/anti-hepatitis B surface (HBs) positive recipients. In this article, we aim to review the mechanisms and risk factors of HBV recurrence post-LT in addition to the various treatment strategies proposed for the prevention of recurrent HBV infection.

Abstract
AIM The incidence of hepatitis B virus (HBV) recurrence after liver transplantation (LT) has been reduced by prophylaxis with hepatitis B immunoglobulin (HBIG) and nucleoside analogs, but the factors associated with HBV recurrence are unclear. The aim of this study was to determine the risk factors associated with HBV recurrence after living donor LT (LDLT). METHODS A retrospective review was performed for 45 patients (28 male and 17 female; median age, 54 years) who underwent LDLT for HBV-related liver disease and were followed up for at least 6 months between October 1996 and June 2013. The virological data, tumor burden, antiviral therapy and immunosuppressive therapy were evaluated and compared between the HBV recurrence ad non-recurrence groups. RESULTS Seven of the 45 patients (15.6%) developed post-LT HBV recurrence. The median interval between LDLT and HBV recurrence was 23.7 months (range, 0.8-35.9). Three of the seven patients (42.9%) developed recurrence after cessation of HBIG, and three (42.9%) were cases with hepatocellular carcinoma (HCC) recurrence after LDLT. The remaining case underwent transplantation from a donor with positive hepatitis B surface antigen. Based on the univariate and multivariate analyses, HBIG cessation (hazard ratio [HR], 20.17; 95% confidence interval [95% CI], 2.091-194.593; P = 0.009) and HCC recurrence (HR, 30.835; 95% CI, 3.132-303.593; P = 0.003) were independent risk factors for HBV recurrence after LDLT. CONCLUSION In LDLT patients, cessation of HBIG and HCC recurrence were risk factors associated with HBV recurrence, so careful monitoring for serological HBV markers is needed in patients with these factors.

Abstract
BACKGROUND Low-dose hepatitis B immunoglobulin (HBIG) and nucleos(t)ides analogs (lamivudine/adefovir) used for the prevention of hepatitis B virus (HBV) recurrence after liver transplantation (LT) are associated with some risk of HBV recurrence and antiviral resistance. METHODS The study cohort included 176 patients (at least >12 months follow-up) with HBV cirrhosis/hepatocellular carcinoma who received secondary prophylaxis with indefinite entecavir/tenofovir after living-donor LT (LDLT). All patients received 10,000 IU intravenous HBIG in anhepatic phase followed by 600-1000 IU intramuscularly daily for 7 days, weekly for 3 weeks, and then monthly, to keep antiHBs levels >100 mIU/mL for 1 year. Hepatitis B surface antigen (HBsAg) and HBV DNA were tested every 6 months. RESULTS The study cohort is composed of 157 men and 19 women, mean age 47.9 ± 10.1 years, all HBsAg positive, 35 (19.8%) had HBV DNA >2000 IU/mL before LT. After LT, patients received entecavir (n = 126, 71.5%), tenofovir (n = 20, 11.3%), or a combination of entecavir and tenofovir (n = 30, 17% for 3 months), followed by entecavir alone. During follow-up of 43 (12-117) months, 2 patients (including 1 with non-compliance) had HBV recurrence. CONCLUSION In a large cohort of LDLT recipients for HBV-related liver disease, use of low-dose short-term HBIG with high genetic barrier drugs results in a substantially lower incidence of HBV recurrence, even in high-risk 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 Currently, most available experience concerning prophylaxis against hepatitis B virus (HBV) recurrence after living donor liver transplantation (LDLT) is limited to studies of small size and short follow-up. The objective of this study was to evaluate the efficacy of a prophylactic regimen using lamivudine and individualized low-dose intramuscular hepatitis B immunoglobulin (HBIG) in LDLT. METHODS We used a database of adult-to-adult right-lobe LDLT procedures performed from June 2002 to April 2012 at our center for HBV-related end-stage liver diseases. Patients were divided into 3 groups: group A, HBV-related decompensated liver cirrhosis; group B, fulminant hepatitis B; and group C, hepatocellular carcinoma (HCC). RESULTS During a mean follow-up of 38.3 ± 28.9 months, 8 of 165 (4.8%) recipients developed HBV recurrences. The mean time for HBV reinfection was 15.8 + 11.0 months after transplantation. The overall 1-, 3-, and 5-year HBV recurrence rates were 3%, 7%, and 8.2%, respectively. Both patients with fulminant hepatitis B or HCC seemed to have higher rates of HBV recurrence than those with decompensated liver cirrhosis, albeit not significantly. The independent predictor of HBV recurrence was high HBV DNA level (≥10(5) copies/mL) at LDLT. CONCLUSIONS Lamivudine and individualized low-dose intramuscular HBIG provides effective prophylaxis against HBV recurrence after LDLT. Pre-LDLT HBV DNA of ≥ 10(5) copies/mL was associated with HBV recurrence.

Abstract
BACKGROUND & AIMS Chronic hepatitis B and hepatitis D are global health problems caused by the human hepatitis B and hepatitis D virus. The myristoylated preS1 domain of the large envelope protein mediates specific binding to hepatocytes by sodium taurocholate co-transporting polypeptide (NTCP). NTCP is a bile salt transporter known to be inhibited by cyclosporin A. This study aimed to characterize the effect of cyclosporin A on HBV/HDV infection. METHODS HepaRG cells, primary human hepatocytes, and susceptible NTCP-expressing hepatoma cell lines were applied for infection experiments. The mode of action of cyclosporin A was studied by comparing the effect of different inhibitors, cyclophilin A/B/C-silenced cell lines as well as NTCP variants and mutants. Bile salt transporter and HBV receptor functions were investigated by taurocholate uptake and quantification of HBVpreS binding. RESULTS Cyclosporin A inhibited hepatitis B and D virus infections during and--less pronounced--prior to virus inoculation. Binding of HBVpreS to NTCP was blocked by cyclosporin A concentrations at 8 μM. An NTCP variant deficient in HBVpreS binding but competent for bile salt transport showed resistance to cyclosporin A. Silencing of cyclophilins A/B/C did not abrogate transporter and receptor inhibition. In contrast, tacrolimus, a cyclophilin-independent calcineurin inhibitor, was inactive. CONCLUSIONS HBV and HDV entry via sodium taurocholate co-transporting polypeptide is inhibited by cyclosporin A. The interaction between the drug and the viral receptor is direct and overlaps with a functional binding site of the preS1 domain, which mediates viral entry.

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 AND AIM Without effective prophylaxis, liver transplantation (LT) for hepatitis B virus (HBV)-related liver disease is frequently complicated by severe and rapidly progressive HBV recurrence. The combination of low-dose hepatitis B immunoglobulin (HBIG) and the new nucleos(t)ide analog, entecavir, as prophylaxis for HBV recurrence after living-donor LT (LDLT) were analyzed. METHODS A total of 315 patients with positive hepatitis B surface antigen underwent LDLT at our transplant center between July 2003 and December 2011. Our protocol for post-transplantation HBV prophylaxis was a combination of low-dose HBIG and nucleos(t)ide analog. RESULTS During a median follow-up period of 49 months post-transplant, 10 patients (3.2%) had HBV recurrence, which was significantly related to hepatocellular carcinoma (HCC) at transplantation (P = 0.041) and post-LT antiviral agent (P < 0.001) in multivariate analysis. The level of HBV DNA and hepatitis B e antigen state at transplantation were not significant factors for HBV recurrence (P = 0.342 and P = 0.802, respectively). In 170 patients with HCC at LDLT, HCC recurrence was significantly related to HBV recurrence (P < 0.001). Among 10 patients with HBV recurrence, three are alive and two had lost hepatitis B surface antigen. The remaining seven patients died of HCC recurrence. CONCLUSIONS The combination of low-dose HBIG and nucleos(t)ide analogs is safe and effective for HBV prophylaxis after LDLT. As a post-LT antiviral treatment, entecavir is more effective than lamivudine. HCC at transplantation was significantly associated with HBV recurrence. HBV-related HCC patients who undergo LDLT require close virological monitoring.

Abstract
Acute liver failure occurs abruptly with rapid progression. Traditional medical treatment and simple non-bioartificial liver support system cannot reverse the prognosis of acute liver failure (ALF), and liver transplantation is the only effective treatment. However, donor liver shortage, the need of a life-long immunosuppressive therapy as well as complex postoperative complications make ALF patients facing a variety of challenges in the perioperative period of liver transplantation, which are directly related to the success rate of surgery and the mortality. This article aims to discuss perioperative difficulties and preventive measures in liver transplantation for ALF by exploring how to extend the lives of patients before liver transplantation and how to deal with postoperative complications.

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
BACKGROUND The tumor burden before liver transplantation indicates that hepatitis B virus (HBV) may hide in the extrahepatic and micrometastatic sites which serve as a source of HBV replication. Currently, many liver transplant centers, especially in Western countries, use the Milan or UCSF criteria to select patients with hepatocellular carcinoma for liver transplantation. This study was undertaken to compare the HBV prophylactic outcomes in two groups of living donor liver transplantation (LDLT) recipients. Patients in group A met the Milan criteria and those in group B exceeded the Milan criteria but were within the UCSF criteria. METHODS A database of adult-to-adult right-lobe LDLT performed at our institution for HBV-related hepatocellular carcinoma within the Milan or UCSF criteria between June 2002 and May 2012 was used to compare the HBV prophylactic outcomes between patients within the Milan criteria (group A, 41 patients) and those exceeding the Milan criteria but within the UCSF criteria (group B, 19 patients). RESULTS The 1-, 3-, and 5-year survival rates were similar between groups A and B (87.8%, 85.1% and 74.0% vs 73.3%, 61.1% and 61.1%, respectively, P=0.067). HBV recurred in 1 patient in 3.1 months after LDLT in group A and in 2 patients in group B (1 in 11.9 months and 1 in 24.1 months after LDLT). The 1-, 3-, and 5-year HBV recurrence rates were 2.6%, 2.6% and 2.6% in group A, and 7.3%, 17.9% and 17.9% in group B, respectively (P=0.118). CONCLUSION LDLT recipients who exceed the Milan criteria but remain within the UCSF criteria may have post-transplant HBV prophylactic outcomes similar to those who meet the Milan criteria.

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 After orthotopic liver transplantation (OLT) in chronic hepatitis B (HBV), adequate prophylaxis for recurrence of HBV in the graft is mandatory. OBJECTIVES Evaluate safety of HBV prophylaxis with tenofovir and emtricitabine (TDF/FTC) after cessation of hepatitis B immunoglobulin (HBIG) after OLT in chronic HBV. STUDY DESIGN In 17 consecutive patients after OLT in chronic HBV we started TDF/FTC after cessation of HBIG. All had received HBIG >6 months. 15/17 were HBsAg negative and 16/17 had undetectable HBV-DNA. RESULTS After mean follow-up of 2 years 16/17 patients were alive, one died due to urosepsis. All 16 with undetectable HBV-DNA remained HBV-DNA negative. From 15 HBsAg negative patients at start, in one seroconversion to positive HBsAg occurred, without detectable HBV-DNA. Liver biochemistry remained within the normal ranges. There were no cases of drug discontinuation. No major side effects were reported. TDF/FTC use saves €16,262/year over standard-of-care (HBIG+LAM). This prospective follow-up study shows that in liver transplantation for chronic hepatitis B, after initial treatment including HBIG for at least 6 months combined with or followed by (dual) nucleos(t)ide analog therapy, TDF/FTC provides adequate prophylaxis against recurrent HBV infection without major side effects and leads to substantial cost savings over a regimen with HBIG. CONCLUSION Combined prophylaxis with TDF/ETV nucleoside plus nucleotide analogs and cessation of immunoglobulin after liver transplantation in chronic hepatitis B is safe and effective.

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
Long-term prophylaxis with hepatitis B immunoglobulin (HBIG) for the prevention of hepatitis B virus (HBV) recurrence after orthotopic liver transplantation (OLT) in patients with chronic HBV infection is inconvenient and costly. This randomized, prospective phase 2 study compared emtricitabine (FTC)/tenofovir disoproxil fumarate (TDF) after HBIG withdrawal to FTC/TDF plus HBIG for the prevention of HBV recurrence after OLT. Forty patients with a median time since liver transplantation of 3.4 years (interquartile range = 1.9-5.6 years) received 24 weeks of open-label FTC/TDF plus HBIG before randomization. Patients who maintained confirmed viral suppression were randomized to continue FTC/TDF plus HBIG (n = 19) or receive FTC/TDF alone (n = 18) for an additional 72 weeks. No patient experienced HBV recurrence through 72 weeks of the study while he or she was receiving the randomized treatment. Both treatment arms were safe and well tolerated; no serious or severe drug-related adverse events were observed. Renal function was consistent with that observed in a posttransplant population. The withdrawal of HBIG after 6 months' treatment with FTC/TDF should be considered in liver transplant recipients to prevent chronic HBV recurrence.

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 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
BACKGROUND A precise predictive survival model of liver transplantation (LT) with antiviral prophylaxis for hepatitis B virus (HBV)-associated hepatocellular carcinoma (HCC) and cirrhosis has not been established. The aim of our study was to identify predictors of outcome after LT in these patients based on tumor staging systems, antitumor therapy pre-LT, and antiviral prophylaxis in patients considered to be unfit by Milan or UCSF criteria. METHODS From 2002 to 2008, 917 LTs with antiviral prophylaxis were performed on patients with HBV-cirrhosis, and 313 had concurrent HCC. RESULTS Stratified univariate and multivariate analyses demonstrated that independent predictors for poor survival were tumor size >7.5 cm (P = 0.001), tumor number >1 (P = 0.005), vascular invasion (P = 0.001), pre-LT serum alpha-fetoprotein (AFP) level ≥1000 ng/ml (P = 0.009), and pre-LT aspartate aminotransferase (AST) level ≥120 IU/L (P = 0.044). Pre-LT therapy for HCC was an independent predictor of better survival (P = 0.028). Based on CLIP and TNM tumor staging systems, HCC patients with HBV-cirrhosis who met the following criteria: solitary tumor ≤7.5 cm, or ≤4 multifocal nodules, the largest lesion ≤5 cm and total tumor diameter ≤10 cm, or more nodules with the largest lesion ≤3 cm, and pre-LT serum AFP level <1000 µg/L and AST level <120 IU/L without vascular invasion and lymph node metastasis who were unfit for UCSF, had survival rates of 89% at 5 years. There was a 47% 5-year survival rate for patients with HCC exceeding the revised criteria. CONCLUSIONS The current criteria for LT based on tumor size, number and levels of AFP and AST may be modestly expanded while still preserving excellent survival after LT. The expanded criteria combined with antiviral prophylaxis and pre-LT adjuvant therapy for HCC may be a rational strategy to prolong survival after LT for HCC patients with HBV-associated cirrhosis.

Abstract
To provide a basis for improved prevention and treatment of hepatitis B virus (HBV) re-infection after liver transplantation, variations in the S and P genes of HBV under immunosuppression in vitro and their association with patient prognosis were investigated. For the in vitro study, HepG2.2.15 hepatocellular carcinoma cells stably producing HBV particles were treated with the immunosuppressants methylprednisolone (MP) and tacrolimus (FK506) at doses found to be non-toxic by the methylthiazolyl tetrazolium (MTT) cell viability assay. MP dose-dependently inhibited HBV DNA expression in HepG2.2.15 cells, while FK506 did not, as determined by quantitative real-time PCR (qRT-PCR). By gene sequencing, both MP and FK506 were found to cause variations in HBV S, P, and S/P overlapping regions. MP- but not FK506-induced mutations were common in the glucocorticoid response element of the P region, while both immunosuppressants caused mutations outside the nucleoside analogue resistance sites. For the in vivo study, 14 patients with HBV-related end-stage liver disease re-infected after liver transplantation, and 20 cases without HBV re-infection as controls, were studied. Seventy-five percent of re-infected recipients showed multi-loci amino acid mutations at different sites besides lamivudine (LAM)-resistant loci in the P region, including in the glucocorticoid response element. Fifty percent of re-infected recipients had mutations in the "a" determinant region and flanking sequences. Re-infection was associated with negative serum hepatitis B immunoglobulin (HBIG), as measured by a microparticle capture enzyme immunoassay. Nucleotide mutations in the S region caused missense or synonymous mutations, which caused synonymous mutations in the overlapping P region. These results showed that effects of immunosuppressants on HBV genes in vitro were different from those in clinical recipients. Positive HBV DNA and gene mutations pre-transplantation were factors affecting re-infection post-transplantation. Multiple mutations found in the P and S genes suggest that the formation of quasispecies contributes to HBV re-infection after liver transplantation.

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.

Hepatol Res 2012; 42:280-7.

Abstract
AIM The aim of this study is to identify the titres of protective hepatitis B surface antibodies (anti-HBs) in the blood and their effective factors in the early stage after liver transplantation (LT) for hepatitis B virus (HBV) related diseases. The condition of anti-HBs lost in ascites fluid was also investigated. METHODS Twenty-six patients who received LT were administered prophylaxis of lamivudine combining intravenous hepatitis B immunoglobulin (HBIG) post-LT. The titres of anti-HBs were recorded and analyzed daily in blood and ascites fluid within the first week post-LT. RESULTS In the first 5 days post-LT, the titres of anti-HBs in HBV DNA positive groups, high hepatitis B surface antigen (HBsAg) groups, hepatitis B e antigen (HBeAg) positive groups were lower than that in the parallel HBV DNA negative groups, low HBsAg groups and HBeAg negative groups. The mean titre level of anti-HBs in ascites fluid is 224.89 IU/L and fluctuated from 0.00 IU/L to 968.50 IU/L, which is also correlated with anti-HBs titres in blood drawn at the same time (r = 0.927, P = 0.000). The level of anit-HBs in ascites fluid was very high; however, it fluctuated in a wide range (from 0.00 IU to 908.55 IU). CONCLUSIONS Patients in high risk groups should receive a higher level of HBIG to maintain sufficient amounts of anti-HBs in the early stage post-LT, while the patients in low risk groups need a lower level of HBIG administration. Furthermore, the lost amount of anti-HBs in ascitic fluid post-LT has minimum impact on the anti-HBs titres in blood.

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).
