Abstract
OBJECTIVES Liver grafts from hepatitis B surface antigen-negative and anti-core antibody-positive donors are safe for liver transplant. However, the use of hepatitis B surface antigen-positive liver donors in liver transplants is controversial. We assessed the safety and effectiveness of liver transplants using hepatitis B surface antigen-positive liver grafts to patients with diseases related to hepatitis B virus. MATERIALS AND METHODS We retrospectively reviewed 23 patients who had a deceased-donor liver transplant using hepatitis B surface antigen-positive liver grafts. All patients had end-stage liver disease secondary to hepatitis B virus infection. Recipients had oral entecavir and intravenous or intramuscular injection of hepatitis B immune globulin for >1 year after the transplant. RESULTS Two patients died from severe perioperative pneumonia, and the other 21 patients were followed for 9 to 38 months after transplant. All 21 patients remained hepatitis B surface antigen-positive. A repeat liver transplant was performed in 1 patient at 5 months after the initial transplant because of biliary ischemia. There were 3 patients who died from recurrent liver cancer at 9, 14, and 18 months after transplant. There were 18 patients (78%) who survived and 17 grafts (74%) that survived. CONCLUSIONS Liver transplant using hepatitis B surface antigen-positive liver grafts is safe for patients with end-stage liver disease secondary to hepatitis B virus infection.

Abstract
The long-lasting persistence of hepatitis B virus (HBV) genomes in the liver (with detectable or undetectable HBV DNA in the serum) of individuals testing negative for the HBV surface antigen (HBsAg) is termed occult HBV infection (OBI). Although in a minority of cases the lack of HBsAg detection is due to infection with variant viruses unrecognized by available assays (S-escape mutants), the typical OBI is related to replication-competent HBVs strongly suppressed in their replication activity. The causes of HBV suppression are not yet well clarified, although the host's immune surveillance and epigenetic mechanisms are likely involved. OBI is a worldwide diffused entity, but the available data of prevalence in various categories of individuals are often contrasting because of the different sensitivity and specificity of the methods used for its detection in many studies. OBI may have an impact in several different clinical contexts. In fact, it can be transmitted (i.e., through blood transfusion and liver transplantation) causing classic forms of hepatitis B in newly infected individuals. The development of an immunosuppressive status (mainly by immunotherapy or chemotherapy) may induce OBI reactivation and development of acute and often severe hepatitis. Finally, evidence suggests that OBI can favor the progression of liver fibrosis, in particular in HCV-infected patients. The possible contribution of OBI to the establishment of cirrhosis also implies its possible indirect role in the development of hepatocellular carcinoma. On the other hand, OBI may maintain most of the direct transforming properties of the overt HBV infection, such as the capacity to integrate in the host's genome and to synthesize pro-oncogenic proteins.

Abstract
Lamivudine has been shown to prevent de novo hepatitis B virus (HBV) infections in liver transplantation (LT) patients receiving hepatitis B core antibody-positive (HBcAb(+)) grafts, but it may produce long-term resistance. Adefovir dipivoxil (ADV) might be effective in preventing de novo hepatitis and resistance. A single-center, prospective trial was conducted with 16 adults (10 men and 6 women, mean age = 54 ± 11 years) who underwent LT with HBcAb(+) grafts between September 2007 and October 2009. After LT, patients were given ADV [10 mg daily (adjusted for renal function)]. No hepatitis B immune globulin was administered. At LT, all graft recipients were hepatitis B surface antigen-negative (HBsAg(-)), 38% were surface antibody-positive (HBsAb(+)), and 50% were HBcAb(+). The median follow-up after LT was 1.8 years (range = 1.0-2.6 years). All recipients had undetectable HBV DNA (<40 IU/mL) after LT until the end of follow-up. One recipient (6%) who was HBsAb(-) and HBcAb(-) before LT became HBsAg(+) after 52 weeks. One recipient was switched from ADV to entecavir for chronic renal insufficiency, and 19% of the patients had renal dose adjustments. There was a nonsignificant trend of increasing creatinine levels over time (1.2 mg/dL at LT, 1.3 mg/dL 1 year after LT, and 2.0 mg/dL 2 years after LT, P = 0.27). A comparison with a control cohort of LT recipients with hepatitis C virus who did not receive ADV showed no difference in the creatinine levels at LT or 1 year after LT. In conclusion, ADV prophylaxis prevents HBV replication in recipients of HBcAb(+) livers but does not fully protect recipients from de novo HBV. Long-term follow-up is needed to better determine the risk of de novo infection.

Abstract
INTRODUCTION The risk of hepatitis B virus (HBV) transmission through donor organs with HBsAg(-) and anti-HBc(+) serology has not been extensively studied in lung transplantation. The objectives of this study are to ascertain the influence of the anti-HBc(+) on the acceptance of the lung for transplantation, to comment on the published literature and to suggest an algorithm for action. METHODS A survey conducted in the 7 Spanish lung transplantation teams. The updated search of the literature was performed using medical databases from 1994 to February 2012. RESULTS All of the teams vaccinate the lung recipients against HBV, although none quantify the anti-HBs titers. When given an anti-HBc(+) donor, 3 teams change their strategy: one does not accept the offer, one selects the receptor from among patients in emergency status and another adds pharmacological prophylaxis. Only 3 publications refer to the serologic evolution of the receptors. At the moment there have been no reported cases of hepatitis B or HBsAg positivity post-transplant, but 4 out of the 50 anti-HBc(-) receptors changed to anti-HBc(+) in the follow-up. CONCLUSIONS The presence of anti-HBc in the donor influences the decision to accept a lung donor, although there is little information on its repercussions. To date, there has been no reported case of transmission of HBV, but post-transplant anti-HBc seroconversions have been described, which suggests contact with viral particles. Although rare, an anti-HBc(+) donor can harbor a hidden HBV infection. The risk of infection can be reduced with adequate anti-HBs titers or with appropriate pharmacological measures.

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
Large volume of new data on the natural history and treatment of chronic hepatitis B virus (HBV) infection have become available since 2008. These include further studies in asymptomatic subjects with chronic HBV infection and community-based cohorts, the role of HBV genotype/naturally occurring HBV mutations, the application of non-invasive assessment of hepatic fibrosis and quantitation of HBV surface antigen and new drug or new strategies towards more effective therapy. To update HBV management guidelines, relevant new data were reviewed and assessed by experts from the region, and the significance of the reported findings was discussed and debated. The earlier "Asian-Pacific consensus statement on the management of chronic hepatitis B" was revised accordingly. The key terms used in the statement were also defined. The new guidelines include general management, indications for fibrosis assessment, time to start or stop drug therapy, choice of drug to initiate therapy, when and how to monitor the patients during and after stopping drug therapy. Recommendations on the therapy of patients in special circumstances, including women in childbearing age, patients with antiviral drug resistance, concurrent viral infection, hepatic decompensation, patients receiving immune suppression or chemotherapy and patients in the setting of liver transplantation and hepatocellular carcinoma, are also included.

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
The reinfection of the hepatic allograft with hepatitis B virus and hepatitis C virus can have important sequelae that result in poor long-term patient and graft survival. Although a response to treatment with antiviral medications can improve these outcomes, not all patients tolerate these medications or experience viral eradication. Avoiding reinfection of the graft is the most effective means of improving the long-term outcomes for these patient populations. This review is focused on the prevention of viral hepatitis reinfection after liver transplantation.

Abstract
Expansion of the donor pool may lead to utilization of donors with risk factors for viral infections. Donor laboratory screening relies on serological and nucleic acid testing (NAT). The increased sensitivity of NAT in low prevalence populations may result in false-positive results (FPR) and may cause unnecessary discard of organs.We developed a screening algorithm to deal, in real time, with potential FPR. Three NAT assays: COBAS AmpliScreen assay (CAS), AmpliPrep Total Nucleic Acid Isolation/CAS, and AmpliPrep/TaqMan assays, were validated and used in parallel for prospective screening of increased-risk donors (IRD), and the probability of FPR was calculated. The lower limit of detection of this algorithm was 9.79, 21.02, and 4.31 IU/mL for human immunodeficiency virus-1, hepatitis C virus, and hepatitis B virus, respectively, with an average turn-around-time of 7.67 h from sample receipt to result reporting. The probability that a donor is potentially infectious with two NAT concordant results was >90%. NAT screening of 35 IRD within 18 months resulted in transplantation of 102 additional organs that without screening would either not be used or used with restrictions in Australia. Using a parallel testing algorithm, real-time confirmation of seropositive donors allows use of organs from IRD and safer expansion of the donor pool.

Abstract
OBJECTIVE There is a significant risk of hepatitis B transmission from HBsAg (-), HBcAb (+) donors in liver transplantation, but there is little information about hepatitis B transmission from HBcAb heart donors. The present study examines the influence of HBcAb presence in relation to heart donor acceptance and offers an update of the published studies. DESIGN Survey and medical database update from 1994 to October 2011. SETTING Spanish heart transplantation teams. PATIENTS Not applicable. STUDY VARIABLES Acceptance of heart transplant from an HBcAb (+) organ donor. RESULTS Twelve out of 15 surveyed teams were seen to vaccinate against HBV, and two quantify HBsAb titers. Seven teams specifically request donor HBcAb status. If the latter proves positive, two do not accept transplantation, two accept if the donor is also HBsAb (+), one selects the receptor under emergency conditions, and three use drug prophylaxis isolatedly or complementary to the above. Only one case of hepatitis B has been reported in a HBcAb (-) and HBsAb (-) receptor that did not receive prophylactic measures. There have been reports of seroconversion of the HBcAb and HBsAb markers, though with an uncertain etiology. CONCLUSIONS HBcAb seropositivity influences acceptance of a heart donor, but agreement is lacking. There is limited information on receptor evolution. To date there has been one reported case of hepatitis B after heart transplant. Although rare, an HBcAb (+) donor can harbor occult HBV infection. The risk of infection can be prevented with appropriate HBsAb titers following vaccination or by pharmacological measures.

Abstract
BACKGROUND & AIMS The main limitation of orthotopic liver transplantation (OLT) is the scarcity of available donor organs. A possibility to increase the organ pool is to use grafts from hepatitis B virus surface antigen (HBsAg) positive donors, but few data are currently available in this setting. We assessed the clinical, serovirological, and immunological outcomes of liver transplant from HBsAg positive donors in a single centre study. METHODS From 2005 to 2009 10 patients underwent OLT from HBsAg positive donors, for HBV-related disease (n=6) or HBV-unrelated disease (n=4). The median follow-up was 42 months (range 12-60). All recipients were HBcAb positive and were given antiviral prophylaxis. RESULTS Patients transplanted for HBV-related disease never cleared HBsAg. Two HBsAg negative patients never tested positive for HBsAg, whereas the others experienced an HBsAg appearance, followed by spontaneous production of anti-HBs, allowing HBsAg clearance. No patient ever had any sign of HBV hepatitis. HBV replication was effectively controlled by antiviral therapy. The immunologic sub-study showed that a most robust anti-HBV specific T cell response was associated with the control of HBV infection. CONCLUSIONS OLT from HBsAg positive donors seems to be a safe procedure in the era of highly effective antiviral therapy.

Abstract
BACKGROUND Fresh-frozen plasma (FFP) may contain antibodies to hepatitis B surface antigen (HBsAg, anti-HBs). These anti-HBs may lead to a misinterpretation of the actual hepatitis B immune status. Furthermore, they may not only confer protection against hepatitis B virus (HBV), but may also favor the selection of HBsAg mutants. CASE REPORT We report a case of de novo HBV infection in a HBV-naïve recipient with alcoholic liver disease, who received a liver from a donor with antibodies to hepatitis B core antigen (HBcAg, anti-HBc) and anti-HBs. RESULTS A lookback investigation revealed the following: 1) Due to anti-HBs passively acquired through FFP, the recipient was considered immune to HBV and did not receive anti-HBV prophylaxis. 2) Within 1 year after transplantation he developed hepatitis B in absence of any elevated liver enzymes after the anti-HBs by FFP declined. 3) Despite an infection with HBV-containing wild-type HBcAg, the patient did not seroconvert to anti-HBc positivity. 4) The replicating HBV encoded two HBsAg mutations, first sQ129R and 4 months later sP127S. They map to the highly conserved “α” determinant of the HBsAg loop. CONCLUSION 1) Passive transfer of anti-HBs from FFP led to an erroneous pretransplant diagnosis of HBV immunity when the patient was in fact HBV-naïve. 2) HBsAg mutations might have been selected in escape from donor's actively produced anti-HBs and the recipient's anti-HBs by FFP might have favored this selection. 3) It is doubtful whether hepatitis B immunoglobulin could have prevented the reactivation. 4) Antiviral prophylaxis would have been crucial.

Abstract
BACKGROUND The inclusion of hepatitis B core antibody-positive (HBcAb+) liver donors is a strategy utilized to increase organ availability. This study examined HBcAb+ transplantation practices to identify specific factors influencing outcomes. METHODS Twenty-five HBcAb+ liver transplants were identified retrospectively among 868 adult transplants performed between 1 January 1997 and 31 December 2009. Twelve (48%) recipients had hepatitis C and five (20%) had hepatitis B. Patient and donor demographics, preoperative morbidity, transplant data and outcomes were examined. Statistical analysis was completed using Student's t-test or the Kaplan-Meier method. A P-value of <0.05 was considered significant. RESULTS There was no difference in age, body mass index or comorbidities between HBcAb+ liver recipients and control subjects. Model for End-stage Liver Disease (MELD) scores of >30 were significantly more frequent in HBcAb+ liver recipients (32% vs. 15%; P= 0.04). All patients received immunoglobulin and longterm antiviral therapy as prophylaxis against graft hepatitis B resurgence. No patients who received HBcAb+ livers developed hepatitis B infection on follow-up. Overall survival at 30 days, 1 year and 5 years in HBcAb+ liver recipients was 92%, 74% and 74%, respectively, compared with 96%, 89% and 76%, respectively, in the control group (P= not significant, log-rank test). All except one of the deaths in the HBcAb+ liver recipient group occurred within 90 days postoperatively and in patients with MELD scores >30. CONCLUSIONS The practice of transplanting HBcAb+ grafts incurs low risk for infection using current methods of prophylaxis. The highest mortality risk was in the early postoperative period, specifically in patients with very high MELD scores. This probably reflects the practice of using positive serology grafts in emergent situations.

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
BACKGROUND The inclusion of hepatitis B core antibody-positive (HBcAb+) liver donors is a strategy utilized to increase organ availability. This study examined HBcAb+ transplantation practices to identify specific factors influencing outcomes. METHODS Twenty-five HBcAb+ liver transplants were identified retrospectively among 868 adult transplants performed between 1 January 1997 and 31 December 2009.

Abstract
BACKGROUND De novo activation of HBV occurs after liver transplantation from hepatitis B surface antigen (HBsAg)-negative and hepatitis B core antibody (anti-HBc)-positive donors, even under hepatitis B immunoglobulin (HBIG) prophylaxis. One reason for the activation of HBV is the emergence of HBV with escape mutations from hepatitis B surface antibody (anti-HBs). The aim of this study is to clarify the clinical features for de novo activation of HBV with anti-HBs escape mutations after liver transplantation. METHODS Clinical features of 75 patients who received HBIG prophylaxis >6 months after liver transplantation with liver grafts from anti-HBc-positive donors were retrospectively analysed. RESULTS Among the 75 recipients, 19 (25%) developed de novo activation of HBV. Of the 19 recipients, the emergence of HBV with anti-HBs escape mutations was confirmed in 7 patients. The rate of de novo activation of HBV with anti-HBs escape mutations was 12% at 5 years. Sequence analysis revealed mutations in the common 'a' determinant region of the surface gene, including G145R, G145A and Q129P, in HBsAg. Administration of entecavir immediately after the occurrence of de novo HBV activation resolved hepatitis and induced clearance of serum HBsAg and HBV DNA in all four patients receiving entecavir. CONCLUSIONS Escape mutations from anti-HBs caused de novo activation of HBV under HBIG prophylaxis after liver transplantation. Early administration of entecavir was effective on de novo activation of HBV with anti-HBs escape mutations.

Abstract
Background/Aims The exclusion of hepatitis B core antibody (HBcAb)-positive donors from liver transplants (LTs) due to the risk of transmitting hepatitis B virus (HBV) does not appear to be practical in Korea, where hepatitis B is endemic. This study assessed the risk of de novo HBV infection in hepatitis B surface antigen (HBsAg)-negative LT recipients receiving a liver from HBcAb-positive donors. Methods Of 341 adult living donor LTs conducted at our institution between March 2001 and September 2008, 176 donors (51.6%) were HBcAb-positive, and 26 HBcAb-positive grafts were transplanted to HBsAg-negative recipients. The median follow-up time after LT was 41.9 months. Results Without anti-HBV prophylaxis, 2 out of 26 (7.7%) HBsAg-negative recipients who received grafts from HBcAb-positive donors developed de novo HBV infection 20 and 85 months after LT. These patients had been negative for all HBV serologic markers before transplantation. In both cases, there were no abnormalities in liver function tests upon diagnosis of de novo HBV infection. Conclusions De novo HBV infection from HBcAb-positive donors after LT does not appear to be of great concern in terms of the number of cases in Korea because high risk patients who are HBV-negative comprise only a small proportion of the recipients. However, HBV-naïve LT recipients still carry the risk of developing de novo HBV infection as in non-HBV endemic areas.

Abstract
BACKGROUND Twenty years ago, liver transplantation for hepatitis B had been a relative contraindication to universal HBV recurrence and poor outcomes. Over the ensuing two decades, there has been refinement of prevention strategies in order to minimize HBV recurrence in the allograft. RESULTS Currently, the most efficacious and cost-effective strategies include newer oral antiviral drugs in combination with low doses of hepatitis B immunoglobulin (HBIG). More recently, strategies have been successful in withdrawing HBIG and newer approaches of HBIG avoidance are currently under development. CONCLUSION Thus, 20 years afterward, HBV recurrence is <5% and outcomes following liver transplantation are excellent.

Abstract
Introduction Selecting a marginal donor in liver transplantation (LT) remains controversial but is necessary because of the small number of available donors. Case presentation A 46-year-old Japanese woman was a candidate to donate her liver to her brother, who had decompensated liver cirrhosis of unknown origin. Eight years before the donation, she had a mild liver dysfunction that was diagnosed as a hepatitis C virus (HCV) infection (serotype 2). She had received anti-viral therapy with interferon α-2b three times weekly for 24 weeks and had a sustained viral response (SVR). A biopsy of her liver before the donation showed normal findings without any active hepatitis, and her serum was negative for HCV-RNA. Only 67 patients have undergone LT from a cadaveric donor in Japan. The family in this case decided to have living donor LT. A careful selection for the liver graft donation was made; however, since she was the only candidate, we approved her as a living donor. She was discharged nine days after the liver donation. Her liver function recovered immediately. A computed tomography scan showed sufficient liver regeneration one year later. Her brother also had good liver function after LT and had no HCV infection 48 months after surgery and no de novo malignancy. Neither of the siblings has developed an HCV infection. Conclusions A patient with SVR status after interferon therapy might be considered a candidate for living donor LT but only if there are no other possibilities of LT for the recipient. A careful follow-up of the donor after donation is needed. The recipient also must have a very close follow-up because it is difficult to predict what might happen to the graft with post-transplant immunosuppression.

Abstract
BACKGROUND AND AIMS Use of grafts from hepatitis B (HBV) core antibody (HBcAb(+)) individuals is a routine transplant practice. Herein, we have reported the results of 20 HBV-negative patients transplanted with a HBcAb-positive liver grafts in order to access the efficacy of HBV prophylaxis using immunoglobulin (IE) and antiviral drugs. METHODS From January 2004 to December 2009, we performed 168 liver transplantations including 38 HBcAb-positive grafts (22.6%) in 18 cases of HBV-positive recipients and 20 HBV-negative recipients. Histological data obtained from these last 20 grafts during retrieval showed an Ishak 1 score in three and no fibrosis in the other cases. HBV prophylaxis included infusion of 10,000 UI IG during the anhepatic phase and every 24 hours for the first 7 days irrespective of the antibody titer as well as lamivudin (100 mg) administered daily. Once discharged, outpatient management provided modulated IG infusions according to when the antibody titer was lower than 400 UI. RESULTS No patient displayed an HBV infection. The overall survival was 80%. Two patients died within the first month after transplantation due to septic complications; one patient succumbed at 24 months after transplantation because of a lymphoproliferative malignancy and another died due to an aggressive hepatitis C virus recurrence at 6 months post transplant. CONCLUSION By using appropriate anti-HBV prophylaxis, HBcAb-positive grafts can be used safely for HBcAb-negative recipients.

Abstract
Occult hepatitis B virus (HBV) infection (OBI), alternatively defined as occult hepatitis B (OHB), is a challenging clinical entity. It is recognized by two main characteristics: absence of HBsAg, and low viral replication. The previous two decades have witnessed a remarkable progress in our understanding of OBI and its clinical implications. Appropriate diagnostic techniques must be adopted. Sensitive HBV DNA amplification assay is the gold standard assay for detection of OBI. Viral as well as host factors are implicated in the pathogenesis of OBI. However, published data reporting the infectivity of OBI by transfusion are limited. Several aspects including OBI transmission, infectivity and its relation to the development of chronic liver diseases and hepatocellular carcinoma have to be resolved. The aim of the present review is to highlight recent data on OBI with a focus on its virological diagnosis and clinical outcome.

Abstract
INTRODUCTION After liver transplant (LT) from Anti-HBc+/HBsAg- donors into HBsAg- recipients, transmission of hepatitis B virus (HBV) may occur (de novo HBV infection). This study analyzes the incidence of de novo HBV infection in HBsAg- recipients of Anti-HBc+/HBsAg- LT with respect to: (i) the recipients' HBV serology and (ii) the type of preventive therapy adopted. METHODS A systematic review of the literature using the electronic database Medline. RESULTS Five hundred and fifty-two LT in 36 articles were selected. Lamivudine, Hepatitis B immune globulin (HBIG), revaccination, and combined therapies were employed in multiple strategies as preventive interventions. Naïve recipients had a high risk of de novo HBV infection, with smaller incidences when HBIG and lamivudine were used, either alone or in association. Vaccinated recipients or those with isolated hepatitis B core antibodies (Anti-HBc) and previous HBV infection had lower risks of viral transmission, additionally reduced by any prophylaxis adoption. DISCUSSION LT from Anti-HBc+/HBsAg- donors into HBsAg- recipients is apparently safe, as long as the recipient is vaccinated or presents an isolated Anti-HBc or previous HBV infection and some prophylaxis is employed. Currently lamivudine seems the best alternative; other nucleoside analogs and revaccination strategies should be considered in future studies. Follow-up and preventive therapies should be maintained for five yr or preferably throughout the recipients' life span.

Abstract
Occult hepatitis B virus (HBV) infection (OBI) is defined as the presence of HBV DNA in the liver (with or without detectable HBV DNA in serum) for individuals testing HBV surface antigen negative. Until recently, the clinical effect of OBI was unclear on the progression of liver disease; on the development of hepatocellular carcinoma; and on the risk for reactivation or transmission of HBV infection. Several studies suggest a high prevalence of OBI among patients with cryptogenic chronic liver disease, but its role in the progression to cirrhosis remains unclear. Although OBI has been well documented in human immunodeficiency virus (HIV)-positive patients, especially among those coinfected with hepatitis C virus, further studies are needed to determine its current clinical impact in HIV setting.

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

Abstract
BACKGROUND The Liver Match is an observational cohort study that prospectively enrolled liver transplantations performed at 20 out of 21 Italian Transplant Centres between June 2007 and May 2009. Aim of the study is to investigate the impact of donor/recipient matching on outcomes. In this report we describe the study methodology and provide a cross-sectional description of donor and recipient characteristics and of graft allocation. METHODS Adult primary transplants performed with deceased heart-beating donors were included. Relevant information on donors and recipients, organ procurement and allocation were prospectively entered in an ad hoc database within the National Transplant Centre web-based Network. Data were blindly analysed by an independent Biostatistical Board. RESULTS The study enrolled 1530 donor/recipient matches. Median donor age was 56 years. Female donors (n = 681, median 58, range 12-92 years) were older than males (n = 849, median 53, range 2-97 years, p < 0.0001). Donors older than 60 years were 42.2%, including 4.2% octogenarians. Brain death was due to non-traumatic causes in 1126 (73.6%) cases. Half of the donor population was overweight, 10.1% was obese and 7.6% diabetic. Hepatitis B core antibody (HBcAb) was present in 245 (16.0%) donors. The median Donor Risk Index (DRI) was 1.57 (>1.7 in 35.8%). The median cold ischaemia time was 7.3h (≥ 10 in 10.6%). Median age of recipients was 54 years, and 77.7% were males. Hepatocellular carcinoma (HCC) was the most frequent indication overall (44.4%), being a coindication in roughly 1/3 of cases, followed by viral cirrhosis without HCC (28.2%) and alcoholic cirrhosis without HCC (10.2%). Hepatitis C virus infection (with or without HCC) was the most frequent etiologic factor (45.9% of the whole population and 71.4% of viral-related cirrhosis), yet hepatitis B virus infection accounted for 28.6% of viral-related cirrhosis, and HBcAb positivity was found in 49.7% of recipients. The median Model for End Stage Liver Disease (MELD) at transplant was 12 in patients with HCC and 18 in those without. Multivariate analysis showed a slight but significant inverse association between DRI and MELD at transplant. CONCLUSIONS The deceased donor population in Italy has a high-risk profile compared to other countries, mainly due to older donor age. Almost half of the grafts are transplanted in recipients with HCC. Higher risk donors tend to be preferentially allocated to recipients with HCC, who are usually less ill and older. No other relevant allocation strategy is currently adopted at national level.

Abstract
Livers from donors positive for antibody against anti-HBc can potentially transmit de novo hepatitis B (DNH) to their recipients. Despite a good outcome, prophylaxis is usually offered to such recipients. There is no consensus on the standard prophylactic regimen and hence prophylaxis varies among different transplant centres. Nonetheless, hepatitis B immune globulin (HBIG) is considered the mainstay of such prophylaxis, either alone or in combination with an oral antiviral treatment. We aim to provide a concise review of the current use of HBIG in prevention of DNH. We also address a few important questions regarding HBIG use.

Abstract
A variety of prophylactic strategies are used to prevent the risk of hepatitis B virus (HBV) transmission from antibody to hepatitis B core antigen (anti-HBc)-positive donors. The mechanisms underlying the failure of HBV immunoglobulin monoprophylaxis have been poorly evaluated. Seventy-seven anti-HBc-positive grafts were used in 21 hepatitis B surface antigen (HBsAg)-positive recipients and 56 HBsAg-negative recipients. HBsAg-positive recipients received prophylaxis comprising hepatitis B immunoglobulins (HBIG) and antiviral agents, 45 HBsAg-negative recipients received a modified HBIG regimen, and 11 HBsAg-negative recipients received no prophylaxis. Both donors and recipients were screened for HBsAg, antibody to HBsAg (anti-HBs) and anti-HBc in their sera and for HBV DNA in both their sera and liver. S gene mutations were investigated after HBV reinfection. HBV infection occurred in 15 HBsAg-negative recipients (19.4%) at a median interval of 16 months (range = 6-67 months) post-transplant and in none of the HBsAg-positive recipients. HBV infections were observed in 31.6% of HBV-naive recipients and 7.7% of HBV-immune recipients receiving HBIG prophylaxis versus 100% of HBV-naive recipients (P = 0.0068) and 33% of HBV-immune recipients (P = 0.08) with no such prophylaxis. S gene mutations were identified in 9 recipients. In conclusion, priority should be given to using anti-HBc positive grafts for HBsAg-positive or HBV-immune recipients. Our study has confirmed the high risk of HBV transmission to naive recipients. HBIG monoprophylaxis was associated with a significant risk of de novo HBV infection and HBV escape mutations. In these patients, we therefore recommend prophylaxis with lamivudine or new nucleos(t)ides analogues. The potential benefits of HBIG prophylaxis combined with antiviral drugs require further evaluations. Long-term prophylaxis is needed because of the long interval of de novo HBV infection post-transplant in some patients.
