Abstract
Viral hepatitis infections are a great burden in children who have received liver transplant. Hepatotropic viruses can cause liver inflammation that can develop into liver graft fibrosis and cirrhosis over the long term. Immunological reactions due to viral hepatitis infections are associated with or can mimic graft rejection, rendering the condition difficult to manage. Prevention strategies using vaccinations are agreeable to patients, safe, cost-effective and practical. Hence, strategies to eliminate viral hepatitis A and B focus mainly on immunization programmes for children who have received a liver transplant. Although a vaccine has been developed to prevent hepatitis C and E viruses, its use is not licensed worldwide. Consequently, eliminating hepatitis C and E viruses mainly involves early detection in children with suspected cases and effective treatment with antiviral therapy. Good hygiene and sanitation are also important to prevent hepatitis A and E infections. Donor blood products and liver grafts should be screened for hepatitis B, C and E in children who are undergoing liver transplantation. Future research on early detection of viral hepatitis infections should include molecular techniques for detecting hepatitis B and E. Moreover, novel antiviral drugs for eradicating viral hepatitis that are highly effective and safe are needed for children who have undergone liver transplantation.

Kim KD, Lee JE, Kim JM, Lee O, Hwang NY, Rhu J, Choi GS, Kim K, Joh JW. Cost-effectiveness and long-term outcomes of liver transplantation using hepatitis B core antibody-positive grafts with hepatitis B immunoglobulin prophylaxis in Korea. Clin Mol Hepatol 2021; 27:603-615. [PMID: 34492755 PMCID: PMC8524070 DOI: 10.3350/cmh.2021.0137] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/16/2021] [Accepted: 09/07/2021] [Indexed: 11/30/2022] Open
Abstract
Background/Aims Hepatitis B core antibody (anti-HBc)-positive donors are used as an extended donor pool, and current guidelines recommend the usage of nucleos(t)ide analogues (NAs) as prophylaxis for preventing de novo hepatitis B virus infection (DNH). We analyzed the long-term outcomes of a large cohort of liver transplantation (LT) patients receiving anti-HBc-positive grafts and evaluated the risk of DNH when hepatitis B immunoglobulin (HBIG) monotherapy was used as prophylaxis. We also compared the cost-effectiveness of HBIG and NAs. Methods We retrospectively reviewed 457 patients with anti-HBc-positive grafts and 898 patients with anti-HBc-negative grafts who underwent LT between January 2001 and December 2018. We compared recipient characteristics according to the anti-HBc status of the donor, and compared the costs of using NAs for the rest of the patient’s life and using HBIG to maintain hepatitis B surface antibody titers above 200 IU/L. Results The 1-, 5-, and 10-year patient survival rates were 87.7%, 73.5%, and 67.7%, respectively, in patients with anti-HBc-positive grafts, and 88.5%, 77.4%, and 70.3%, respectively, in patients with anti-HBc-negative grafts (P=0.113). Among 457 recipients with anti-HBc-positive grafts, 117 (25.6%) were non-HBV recipients. The overall incidence of DNH was 0.9%. When using HBIG under insurance coverage, the cumulative cost was lower compared with using NA continuously without insurance coverage in Korea. Conclusions Anti-HBc-positive grafts alone do not affect patient survival or graft survival. HBIG monoprophylaxis has good outcomes for preventing DNH, and the patient’s long-term cost burden is low in Korea because of the national insurance system in this cohort.

Abstract
The use of hepatitis B core antibody (anti-HBc)-positive grafts is one strategy for expanding the donor pool for liver transplantation (LT). The aim of this study was to determine the risk factors associated with hepatitis B virus (HBV) recurrence after living donor LT (LDLT) of anti-HBc-positive grafts. From January 1996 to December 2018, a total of 609 LDLT procedures were performed at our center. A retrospective review was performed for 31 patients (23 males and 8 females; median age = 47 years) who underwent LDLT for HBV-unrelated liver disease from anti-HBc-positive donors. The factors associated with HBV recurrence were evaluated and compared between the HBV recurrence and non-recurrence groups. The median follow-up period after LT was 135 months (range, 6-273 months). Four of 31 patients (12.9%) developed post-LT HBV recurrence. All four cases were HBV-naïve patients (anti-HBc-negative and Hepatitis B surface antibody-negative). The median interval between LDLT and HBV recurrence was 42 months (range, 20-51). The overall actuarial rates of HBV recurrence at 1, 3, 5, 10, and 20 years were 0%, 7.2%, 15.7%, 15.7%, and 15.7%, respectively. Although there were no significant differences between the HBV recurrence and non-recurrence groups, HBV recurrence tended to occur in HBV-naïve recipients (P = 0.093). HBV-naïve status may contribute to HBV recurrence after LDLT for HBV-unrelated liver disease from anti-HBc-positive donors. Careful monitoring for serological HBV markers is needed, particularly in this group.

Abstract
Chronic hepatitis B (CHB) is a major global health problem affecting an estimated 350 million people with more than 786000 individuals dying annually due to complications, such as cirrhosis, liver failure and hepatocellular carcinoma (HCC). Liver transplantation (LT) is considered gold standard for treatment of hepatitis B virus (HBV)-related liver failure and HCC. However, post-transplant viral reactivation can be detrimental to allograft function, leading to poor survival. Prophylaxis with high-dose hepatitis B immunoglobulin (HBIG) and anti-viral drugs have achieved remarkable progress in LT by suppressing viral replication and improving long-term survival. The combination of lamivudine (LAM) plus HBIG has been for many years the most widely used. However, life-long HBIG use is both cumbersome and costly, whereas long-term use of LAM results in resistant virus. Recently, in an effort to develop HBIG-free protocols, high potency nucleos(t)ide analogues, such as Entecavir or Tenofovir, have been tried either as monotherapy or in combination with low-dose HBIG with excellent results. Current focus is on novel antiviral targets, especially for covalently closed circular DNA (cccDNA), in an effort to eradicate HBV infection instead of viral suppression. However, there are several other molecular mechanisms through which HBV may reactivate and need equal attention. The purpose of this review is to address post-LT HBV reactivation, its risk factors, underlying molecular mechanisms, and recent advancements and future of anti-viral therapy.

Abstract
AIM Hepatitis B virus (HBV) reactivation after liver transplantation in HBV patients, or in HBV negative recipients of anti-hepatitis B core (HBc) positive grafts, has been prevented by prophylactic use of hepatitis B immunoglobulin (HBIG) and/or nucleoside/nucleotide analogs (NA). Vaccination against HBV is an alternative that may provide a chance to discontinue prophylaxis by producing anti-hepatitis B surface (HBs) antibodies. METHODS We retrospectively reviewed 40 HBV positive recipients (HBV+ group) and 27 HBV negative recipients of anti-HBc positive grafts (HBV-/anti-HBc+ graft group), who were administrated double-dose hepatitis B vaccination. Recipients were regarded as responders when anti-HBs greater than 100 IU/L was maintained for 6 months or more without HBIG. Response rates of vaccine and long-term outcomes were analyzed. RESULTS Eighteen of the 40 patients in the HBV+ group (45%) and 18 of the 27 patients in the HBV-/anti-HBc+ graft group (67%) responded to vaccination after a median of four and three times, respectively. Younger age was the only independent factor associated with vaccine response in the HBV-/anti-HBc+ graft group (P = 0.03), whereas no factor was found to be an independent predictor for vaccine response in the HBV+ group. Among the 18 responders in the HBV+ group, 17 remained without NA or HBIG 8.2 years after the start of vaccination. Ten of those required periodic booster vaccination. All 18 responders in the HBV-/anti-HBc+ graft group remained free from HBV prophylaxis 6.2 years after the start of vaccination. CONCLUSION Younger recipients have a greater chance to develop sufficient anti-HBs after double-dose HBV vaccination, leading to discontinue HBV prophylaxis.

Abstract
The growing demand for organ donors to supply the increasing number of patients on kidney waiting lists has led most transplant centers to develop protocols that allow safe use of organs from donors with special clinical situations previously regarded as contraindications. Deceased donors with previous hepatitis B may be a safe resource to increase the donor pool even if there is still controversy among transplantation centers regarding the use of hepatitis B surface antigen-positive donors for renal transplantation. However, when allocated to serology-matched recipients, kidney transplantation from donors with hepatitis B may result in excellent short-term outcome. Many concerns may arise in the long-term outcome, and studies must address the evaluation of the progression of liver disease and the rate of reactivation of liver disease in the recipients. Accurate selection and matching of both donor and recipient and correct post-transplant management are needed to achieve satisfactory long-term outcomes.

Abstract
AIM The feasibility of vaccination in liver transplant recipients is highly controversial, and the present study aimed to investigate the efficacy of a 1-year extended, monthly vaccine prophylaxis protocol of a second-generation recombinant vaccine for transplant recipients. METHODS The recombinant hepatitis B vaccine (10 µg) was administrated s.c. every month for 12 months as the vaccination protocol to 39 liver transplant recipients in stable condition, including those with hepatitis B-related chronic liver disease (n = 30), those with acute hepatitis B liver failure (hepatitis B surface antibody [HBsAb], n = 4), and those with hepatitis B core antibody positive grafts (n = 5). A fixed dose of hepatitis B immune globulin (HBIG) was administrated during the study based on the monoprophylaxis approach, and the increase in the hepatitis B surface antibody titer was measured to evaluate the efficacy of the vaccination. RESULTS The vaccination protocol was initiated a mean of 54 months (range, 13-124) after liver transplantation, and all patients tolerated the vaccination well without adverse effects. The overall hepatitis B virus (HBV) recurrence rate was 5% (2/39) based on hepatitis B surface antigen positivity, and 2% (1/39) based on HBV DNA detectability. Six (15%) patients showed a good response to vaccination with an increase in the HBsAb titer greater than 100 IU/L at the end of vaccination, but only three (8%) maintained an adequate HBsAb level to spare HBIG during the 2-year observation period. CONCLUSION While a few patients demonstrated an adequate response to vaccination, the clinical indication for the HBV vaccination for liver transplant recipients is currently minimal.

Abstract
De novo hepatitis B infection in patients receiving liver transplants from hepatitis B core antibody-positive donors is well known, but the effective prevention strategy has not been well established. In our hospital, recipients receive hepatitis B immunoglobulin monotherapy if they are hepatitis B surface antigen negative at the time of transplant and are receiving a liver from a hepatitis B core antibody-positive donor. Since August 2006, we have had 4 patients who were naïve to hepatitis B virus and received a hepatitis B core antibody-positive graft. Two patients died of other causes, and 2 patients, who had liver transplant in October 2006 and October 2009, developed de novo hepatitis B. Both patients were tested annually for serum hepatitis B surface antigen as part of routine visit. Tests were negative; however, both patients recently became hepatitis B surface antigen positive. Other laboratory results, including liver function test, were unremarkable, except HBsAb titer was undetectable even though hepatitis B immunoglobulin monotherapy had been administrated 2 months previously in both patients. The patients had hepatitis B virus DNA levels of 3.07E+08 copies/mL and 1.51E+08 copies/mL. We suggest that additional prophylactic therapies above hepatitis B immunoglobulin monotherapy are needed for these recipients.

Abstract
This document was developed through the collaborative efforts of the Society of Critical Care Medicine, the American College of Chest Physicians, and the Association of Organ Procurement Organizations. Under the auspices of these societies, a multidisciplinary, multi-institutional task force was convened, incorporating expertise in critical care medicine, organ donor management, and transplantation. Members of the task force were divided into 13 subcommittees, each focused on one of the following general or organ-specific areas: death determination using neurologic criteria, donation after circulatory death determination, authorization process, general contraindications to donation, hemodynamic management, endocrine dysfunction and hormone replacement therapy, pediatric donor management, cardiac donation, lung donation, liver donation, kidney donation, small bowel donation, and pancreas donation. Subcommittees were charged with generating a series of management-related questions related to their topic. For each question, subcommittees provided a summary of relevant literature and specific recommendations. The specific recommendations were approved by all members of the task force and then assembled into a complete document. Because the available literature was overwhelmingly comprised of observational studies and case series, representing low-quality evidence, a decision was made that the document would assume the form of a consensus statement rather than a formally graded guideline. The goal of this document is to provide critical care practitioners with essential information and practical recommendations related to management of the potential organ donor, based on the available literature and expert consensus.

Abstract
Liver transplantation success is limited by the availability of donors. To overcome this limitation, anti-core-positive donors are increasingly being accepted, but underutilization of this resource still occurs. We performed the current study to determine the prevalence of anti-core-positive donors in our region and to describe the management of these donors and their recipients. Between January 2005 and July 2011, the national transplant database included 2,262 registered liver donors among whom 106 (4.7%) were anti-core-positive including 59 (56%) discarded and 47 (44%) implanted organs. A median of 14.5 offers (range 4-60) were rejected before harvesting and implanting the accepted grafts. The only difference between the implanted and the discarded grafts was found for the alanine aminotransferase level, which was higher among the discarded ones (50 ± 59 UI/L vs 25 ± 16, P < .05). Among 40 recipients included in the study, 5 (12.5%) did not receive any prophylaxis; 18 (45%) a nucleos(t)ide analog 11 (25.5%), heptitis B immunoglobulin and nucleos(t)ide analogs and 6 (15%) pretransplant hepatitis B vaccination. Over a mean follow-up of 871 ± 585 days, 4 de novo hepatitis B cases were identified at 545, 720, 748, and 1,080 days posttransplantation. None of these patients had received any prophylaxis. In all cases entecavir successfully controlled viral replication. We believe that better utilization of these donors and careful management of their recipients represent safe strategies to expand the liver donor pool in Argentina.

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

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
SkagenMany transplant programs utilize liver grafts from hepatitis-B core antibody (HBcAb)-positive and hepatitis-B surface antigen (HBsAg)-negative donors. However, there is risk for de novo hepatitis B (DNH) in recipients of these grafts. We reviewed 26 studies reporting the rates of DNH in recipients receiving HBcAb-positive liver grafts. Four hundred and sixty-two donor-recipient pairs were included to evaluate the risk of DNH stratified by the recipient's immune status to hepatitis B and type of prophylactic therapy given, if any. The rate of DNH was highest (58%) in the stratum of hepatitis-B (HBV) naïve recipients who did not receive prophylaxis. In HBV naïve recipients, prophylactic therapy (lamivudine and/or hepatitis-B immunoglobulin - HBIG) reduced DNH to 11% (odds ratio [OR] = 11.1, 95% CI 4.98-25, p < 0.0001 for DNH without prophylaxis). Recipients with hepatitis-B surface antibody (HBsAb) positivity had DNH rates of 18% without prophylaxis and 0% with prophylaxis (OR = 9.2, 95% CI 1.1-83.3, p = 0.039). Recipients with both HBsAb and HBcAb positivity had DNH rates of 4% without prophylaxis and 3% with prophylaxis (p = 1.00), while recipients with HBcAb positivity alone had DNH rates of 14% without prophylaxis and 3% with prophylaxis (p = 0.21). There was no significant difference between the types of HBV prophylaxis received whether lamivudine, HBIG or both. However, in the subgroup who received HBIG alone, rates of DNH were higher after cessation of HBIG prophylaxis compared to DNH rates with indefinite HBIG (p = 0.0002). In summary, the risk of DNH is highest for HBV naïve liver recipients from HBcAb-positive donors. Recipients who are HBV naïve as well as those recipients with isolated HBsAb positivity derive significant benefit from HBV prophylaxis after transplantation with a HBcAb-positive graft. The ideal prophylactic regimen for prevention of DNH is unclear, but based on our analysis of the literature, antivirals alone may suffice. More data are needed with the newer antivirals for hepatitis B.

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
Although the combination of lamivudine (LAM) and high-dose intravenous (IV) hepatitis B immunoglobulin (HBIG) is very effective in preventing hepatitis B virus (HBV) recurrence after liver transplantation (LT), the major limitation of this regimen is its high cost. A more cost-effective, convenient and widely accepted regimen is urgently needed. We evaluated the safety and efficacy of another strategy using LAM and individualized low-dose intramuscular (IM) HBIG. Between May 2002 and December 2009, a total of 254 adult patients undergoing LT for HBV-related benign end-stage liver diseases received this regimen in our center. The mean follow-up of these patients was 41.2 +/- 22.7 months. Their 1-, 3- and 5-year survival rates were 85.3%, 77.4% and 76.4%, respectively, and 1-, 3- and 5-year HBV recurrence rates were 2.3%, 6.2% and 8.2%. Fourteen patients experienced posttransplant HBV recurrence. Pretransplant high viral load and posttransplant prednisone withdrawal time were observed to be associated with recurrence. In conclusion, combination therapy with LAM and individualized low-dose IM HBIG provides a safe and effective prophylaxis against HBV recurrence after LT at about 5% of the cost of conventional high-dose IV HBIG regimens.

Abstract
BACKGROUND & AIMS Although hepatitis B virus (HBV) transmission after liver transplantation of grafts from HBsAg-negative, anti-HBc positive donors is well established, the growing organ shortage favours the use of such marginal grafts. We systematically evaluated the risk of HBV infection after liver transplantation with such grafts and the effect of anti-HBV prophylaxis. METHODS We performed a literature review over the last 15 years identifying 39 studies including 903 recipients of anti-HBc positive liver grafts. RESULTS Recurrent HBV infection developed in 11% of HBsAg-positive liver transplant recipients of anti-HBc positive grafts, while survival was similar (67-100%) to HBsAg-positive recipients of anti-HBc negative grafts. De novo HBV infection developed in 19% of HBsAg-negative recipients being less frequent in anti-HBc/anti-HBs positive than HBV naive cases without prophylaxis (15% vs 48%, p<0.001). Anti-HBV prophylaxis reduced de novo infection rates in both anti-HBc/anti-HBs positive (3%) and HBV naive recipients (12%). De novo infection rates were 19%, 2.6% and 2.8% in HBsAg-negative recipients under hepatitis B immunoglobulin, lamivudine and their combination, respectively. CONCLUSIONS Liver grafts from anti-HBc positive donors can be safely used, preferentially in HBsAg-positive or anti-HBc/anti-HBs positive recipients. HBsAg-negative recipients should receive prophylaxis with lamivudine, while both anti-HBc and anti-HBs positive recipients may need no prophylaxis at all.

Abstract
The characteristics of hepatitis B virus (HBV) in vaccinated children who acquire de novo HBV infections after orthotopic liver transplantation (OLT) remain largely unknown. The aim of this study was to explore HBV mutants in pediatric OLT recipients with de novo HBV infections. In all, 50 recipients underwent OLT between December 1997 and October 2005, and they were regularly checked for HBV serum markers from November 2005 to April 2009. Before OLT, all were hepatitis B surface antigen (HBsAg)-negative and under the coverage of the universal infant HBV vaccination program. Those who became HBsAg-positive after OLT were diagnosed with de novo HBV infection. HBV viral loads and full-length genome sequencing were determined when the diagnosis of de novo HBV infection was established. Nine patients (9/50, 18%) acquired de novo HBV infections after OLT. None had graft loss or fulminant hepatitis. Five cleared HBsAg, and 4 of the 5 even recovered with antibody to hepatitis B surface antigen (anti-HBs) formation. The other 4 were persistently HBsAg-positive. Mutations in the major S gene (681 base pairs) were discovered in 8 (88.9%) of the de novo HBV-infected children. Six of them harbored mutations within the "a" determinant region (codons 124-147), whereas the other 2 had mutations outside this region. These 2 cleared HBsAg and recovered with anti-HBs formation. HBV DNA levels were not different between those who cleared HBsAg and those who did not. In conclusion, surface mutants are frequent among pediatric liver transplant recipients with de novo HBV infections, but their clinical relevance requires further study.

Abstract
Prophylactic strategies against hepatitis B virus (HBV) recurrence after liver transplantation (LT) are essential for patients with HBV-related disease. Before LT, lamivudine (LAM) was proposed to be down-graded from first- to second-line therapy. In contrast, adefovir dipivoxil (ADV) has been approved not only as first-line therapy but also as rescue therapy for patients with LAM resistance. Furthermore, combination of ADV and LAM may result in lower risk of ADV resistance than ADV monotherapy. Other new drugs such as entecavir, telbivudine and tenofovir, are probably candidates for the treatment of hepatitis-B-surface-antigen-positive patients awaiting LT. After LT, low-dose intramuscular hepatitis B immunoglobulin (HBIG), in combination with LAM, has been regarded as the most cost-effective regimen for the prevention of post-transplant HBV recurrence in recipients without pretransplant LAM resistance and rapidly accepted in many transplant centers. With the introduction of new antiviral drugs, new hepatitis B vaccine and its new adjuvants, post-transplant HBIG-free therapeutic regimens with new oral antiviral drug combinations or active HBV vaccination combined with adjuvants will be promising, particularly in those patients with low risk of HBV recurrence.

Abstract
OBJECTIVE De novo hepatitis B virus (HBV) infection is defined as infection occurring in HBV surface antigen (HBsAg)-negative patients who become HbsAg positive after organ transplantation. We assessed the incidence and risk factors of de novo HBV infection in pediatric liver transplant recipients. PATIENTS AND METHODS From 1996 to 2006, 71 Taiwanese children with non-HBV-related liver diseases underwent orthotopic liver transplantation (OLT) at the National Taiwan University Hospital. All of the surviving recipients were tested regularly for liver function, serum levels of immunosuppressant, HBsAg, titers of antibodies to hepatitis B surface antigen (anti-HBs), antibodies to hepatitis B core antigen (anti-HBc), and antibodies to hepatitis C virus (anti-HCV). HBV vaccination histories and the anti-HBs titers before OLT were recorded. No regular prophylaxis was given. RESULTS Fifty-nine patients (33 girls and 26 boys) were followed up for a median of 4.4 years (range 1.0-10.0). Of those, 36 (61.0%) received allografts from anti-HBc-positive and HBsAg-negative donors. De novo HBV infection was found in 9 (15.3%) patients after OLT, 8 of whom received allografts from HBsAg-negative and anti-HBc-positive donors. Forty-eight (81.4%) patients received 3 or more doses of HBV vaccine before OLT. Pre-OLT anti-HBs titers were available for 49 recipients. Of the 9 de novo HBV-infected recipients, 8 had anti-HBs titers <200 mIU/mL. No graft loss or fulminant hepatitis was noted. CONCLUSIONS In the absence of adequate prophylaxis, the incidence of de novo HBV infection in pediatric OLT recipients is 15.3%. An anti-HBs titer of >200 mIU/mL before OLT may be sufficient to prevent de novo HBV infection in HBsAg-negative recipients.

Abstract
AIMS Post-transplant active immunization for chronic hepatitis B patients has been attempted in several studies with controversial results. We assessed the effect of a double-dose double-phase vaccination regimen among partial living donor liver recipients. METHODS Eighteen patients who underwent liver transplantation (LT) for chronic hepatitis B and two non-hepatitis B virus (HBV)-infected patients who received hepatitis B core antibody (HBcAb)-positive donor organs were recruited 18-78 months after LT. All were on hepatitis B immunoglobulin (HBIG) mono-prophylaxis before and throughout vaccination, to maintain hepatitis B surface antibody (HBsAb) titers of more than 100 IU/mL. Recombinant hepatitis B surface antigen vaccine (40 microg) was administered intramuscularly during weeks 0, 4, 8, 24, 28 and 32. RESULTS The patients consisted of 15 males and five females with a median age of 52 (39-59) years. None developed a sufficient HBsAb titer above 500 IU/mL by week 48. In two patients whose maximum HBsAb titer increased to above 300 IU/mL, we attempted to skip HBIG, but shortly thereafter the titer dropped below 100 IU/mL and HBIG administration was resumed. Although the HBIG dose was reduced during and after vaccination, cessation of administration was not achieved. CONCLUSION Double-dose double-phase use of second generation recombinant vaccine was not effective in this study population. The selected population should be targeted for a conventional vaccine regimen, and different approaches, such as strong adjuvant or pre-S containing protein, should be further tested in a larger number of patients after LT for chronic hepatitis B.
