Abstract
Hepatitis B virus (HBV) reactivation reportedly occurs frequently after hematopoietic stem cell transplantation (HSCT) in resolved HBV-infected patients. Here, 50 patients with resolved HBV infections and scheduled to undergo HSCT were enrolled; all subjects were vaccinated with three doses of hepatitis B vaccine 12 months after HSCT and the incidence of HBV reactivation was monitored. The patients' characteristics were: median age, 61 (34-72) years; male/female, 27/19; allogeneic/autologous, 40/6; bone marrow/peripheral blood stem cells/cord blood, 26/16/4. Of the 46 patients who underwent HSCT, 19 were excluded and did not make it to vaccination due to relapse of underlying disease, HBV reactivation within 12 months of HSCT, or transfer of patients. The remaining 27 were vaccinated 12 months after HSCT and monitored for 2 years. Six showed HBV reactivation, with a 2-year cumulative reactivation incidence of 22.2%; the same incidence was 27.3% only in allogeneic HSCT patients. Factors associated with HBV reactivation included the discontinuation of immunosuppressants (P = 0.0379) and baseline titers of antibody against hepatitis B surface antigen (P = 0.004). HBV reactivation with vaccination following HSCT could occur despite maintenance of serum anti-HBs at more than protective levels.

Abstract
Reactivation of hepatitis B virus (HBV) by reverse seroconversion (HBV-RS) after allogeneic haematopoietic stem cell transplantation (allo-HSCT) can occur in patients with resolved HBV infection (rHBV, defined as negative HBV surface antigen [HBsAg] and positive HBV core antibody), and may cause fatal hepatitis. To explore the risk factors, we retrospectively identified 817 consecutive patients who underwent allo-HSCT from 2005 to 2016 in this largest single centre cohort from National Taiwan Univerisity Hospital. Transplants using donors or recipients positive for HBsAg or HBV DNA were excluded, leaving 445 rHBV patients for analysis. The 3- and 5-year cumulative incidence of HBV-RS after allo-HSCT was 8·7% and 10·5%, respectively, at a median 16 months after allo-HSCT. All had concurrent HBV reactivation. HBV flares developed in 19% of HBV-RS cases, but none experienced hepatic failure. Neither did it impact non-relapse mortality or overall survival. Multivariate analysis revealed that patients with donor lacking hepatitis B surface antibody and extensive chronic graft-versus-host disease (cGVHD) have the highest risk for HBV-RS, with 5-year incidence of 24·2%. In conclusion, adoptive immunity transfer from the donor seems to have protective effects against HBV-RS, which may alter future donor selection algorithms, and combined with extensive cGVHD provides a good target for risk-adaptive HBV prophylaxis.

Reactivation of resolved hepatitis B virus infection combined with nephrotic syndrome in a patient after allogeneic haematopoietic stem cell transplantation. BMC Infect Dis 2019; 19:57. [PMID: 30651070 PMCID: PMC6335709 DOI: 10.1186/s12879-019-3690-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2018] [Accepted: 01/07/2019] [Indexed: 12/01/2022] Open
Abstract
Background After allogeneic haematopoietic stem cell transplantation (allo-HSCT), Hepatitis B virus reactivation (HBVr) can be observed in patients with previous resolved Hepatitis B virus (HBV) infections. Nephrotic syndrome (NS) is the main clinical manifestation of HBsAg-positive glomerulonephritis. However, the development of HBVr combined with NS after allo-HSCT is uncommon. Case presentation We presented a case of a 47-year-old female with acute myelogenous leukemia who underwent HLA-identical sibling allo-HSCT and achieved leukemia free survival. She had pretransplant serological markers of a resolved HBV infection (HBsAg-negative, anti-HBc and anti-HBs positive). However, she developed HBVr combined with nephrotic syndrome (NS) 16 months after HSCT. Her histological renal lesion was mesangial proliferative glomerulonephritis. IgA+, IgM+, and C1q deposits but not HBV antigens (HBsAg and HBcAg) were identified in her renal biopsy material. Long-term entecavir and immunosuppression resulted in decrease of HBV virus replication, amelioration of proteinuria and stabilisation of renal function. Conclusions Entecavir combined with immunosuppression has efficacy in the treatment of HBVr combined with NS after allo-HSCT, but long course of treatment is needed. Closely monitoring and antiviral prophylaxis might be necessary for allo-HSCT recipients to prevent reactivation of resolved HBV infection and its related complications.

Impact of Hepatitis B Core Antibody Seropositivity on the Outcome of Autologous Hematopoietic Stem Cell Transplantation for Multiple Myeloma. Biol Blood Marrow Transplant 2017; 23:581-587.

Abstract
Hepatitis B core antibody (HBcAb) seropositivity has been associated with a higher rate of hepatitis B virus (HBV) reactivation after chemotherapy, even in patients who are hepatitis B surface antigen (HBsAg) negative. However, little is known about the risk of HBV reactivation after autologous hematopoietic stem cell transplantation (auto-HCT). We evaluated the incidence of HBV reactivation, liver toxicity, and survival in patients with multiple myeloma (MM) who received auto-HCT at our institution. We retrospectively identified 107 MM patients with resolved HBV infection (HBcAb positive, HBsAg negative) and 125 patients with negative HBV serology (control subjects) who were matched for age, timing of auto-HCT from diagnosis, cytogenetics, disease status at transplant, induction therapy, and preparative regimen. All patients underwent auto-HCT between 1991 and 2013. Primary endpoints were HBV reactivation, defined as HBsAg positivity or ≥10-fold increase in HBV DNA, and hepatotoxicity, as defined in the U.S. National Cancer Institute Common Terminology Criteria for Adverse Events v3.0. In the resolved HBV infection group, 52 patients (49%) were HBsAb positive and 24 (22%) had detectable HBV DNA before auto-HCT. Only 1 patient with resolved HBV infection received pre-emptive antiviral therapy with lamivudine, whereas 4 patients received lamivudine (n = 3) or tenofovir (n = 1) at reactivation after auto-HCT for a median duration of 12 months. HBV reactivation occurred in 7 of 107 patients (6.5%) in the resolved HBV group. Median time to HBV reactivation from auto-HCT was 16 months. The cumulative incidence of grade 2 or greater hepatotoxicity was 30% in the resolved HBV infection group and 22% in the control group (hazard ratio, 1.3; 95% confidence interval, .7 to 2.3; P = .4). Nonrelapse mortality for the 2 groups was not statistically different at 2 years (P = .06), although it trended higher in the control group than in the resolved HBV infection group (8% versus 1%). The median progression-free survival (PFS) and overall survival (OS) durations in the resolved HBV infection and control groups were 21 versus 18 months (P = .5) and 53 versus 67 months (P = .2), respectively. Our data suggest that resolved HBV infection in patients undergoing auto-HCT for MM is associated with a low risk of HBV reactivation and hepatotoxicity; these complications were reversible and did not adversely affect the PFS or OS.

Abstract
We present an 18-yr-old adolescent with acute lymphocytic leukemia, who underwent peripheral blood SCT with serologically and histologically documented chronic hepatitis B infection. Prior and during the transplant process, lamivudine was administered orally and he underwent SCT with a twofold decrease in viral load at the time of transplant from his HLA full matched, HBV natural immune (anti-HBs and anti-HBc positive) donor. Successful engraftment was achieved and three months after SCT, HBV seroconversion was documented accompanied with an ALT flare. Chronic graft-versus-host disease coincided after the transplantation, and he has been on immunosuppressive treatment for 25 months with sustained HBV seroconversion. We assume that adoptive immunity transfer combined with antiviral treatment might also constitute sustained seroconversion in chronic HBV, besides the reported risk of reactivation.

Changes of hepatitis B virus serologic status after allogeneic hematopoietic stem cell transplantation and impact of donor immunity on hepatitis B virus. Biol Blood Marrow Transplant 2011; 17:1630-7.

Abstract
Reverse seroconversion (RS) of Hepatitis B virus (HBV) has been reported after allogeneic transplantation with an incidence of 14% to 86%. However, most prior studies on HBV RS were performed in HBV nonendemic areas. In this study, the frequency of HBV RS at a single center in Korea, endemic for HBV, was evaluated. Also, the influence of the donor's immunity for HBV on posttransplantation HBV serologic changes in recipients was also investigated. A total of 288 patients underwent allogeneic transplantation between February 1996 and June 2008. We retrospectively reviewed the medical records of 288 patients and their paired donors. Among the 268 HBsAg(-) patients, 205 were assessed for posttransplantation HBsAg, and 114 (55.6%) of 205 had HBcAb before transplantation. With a median follow-up of 77.9 months, 3 of 114 patients experienced HBV RS (2.6%). With regard to donor immunity, significantly more patients with anti-HBs(-) donors experienced anti-HBs loss (P = .006), and the donor anti-HBs showed significant protective effects against the anti-HBs loss with an HR of 0.4. HBV RS after allogeneic transplantation may not be as common in HBV endemic areas. Also, donor anti-HBs showed a significant favorable effect on maintaining HBV immunity in recipients.

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
Epidemiological studies have revealed that hepatocellular carcinoma (HCC) is still observed in hepatitis C virus (HCV)-positive patients with a sustained response to interferon (IFN) treatment, although a substantial decrease in the incidence of hepatocellular carcinoma (HCC) has been achieved in those patients. Why HCC develops in patients who have a complete clearance of HCV remains unclear. Here, we provided evidence of latent hepatitis B virus (HBV) infection in an initially HCV-positive chronic hepatitis patient who developed HCC after the complete eradication of HCV by IFN therapy. Although he was initially negative for anti-hepatitis B surface antigen (HBsAg) or circulating HBV DNA but positive for anti-hepatitis B core antigen (anti-HBc) in his sera, he developed HBsAg and HBV DNA during the course of the management of a series of cancers. HBV DNA was detectable in the liver tissues before HBV reactivation and the viral sequences derived from his anti-HBc-positive liver showed 100% homology to that from the serum after HBsAg appearance. These findings indicates that HCV-positive individuals who are positive for anti-HBc in the absence of HBsAg could have latent HBV infection in their liver tissues and intrahepatic HBV infection may play a pivotal role in the development of HCC after the IFN-mediated eradication of HCV.

Abstract
Serologic evidence of resolved hepatitis B virus (HBV) infection has been associated with reactivation of hepatitis after allogeneic hematopoietic stem cell transplantation (allo-HSCT), but the true impact of this finding is unknown. We conducted a retrospective matched-control analysis of the outcomes of 76 patients with positive HBV core antibody (HBcAb) and negative HBV surface antigen (HBsAg) at the time of allo-HSCT for hematologic or solid malignancies. Control patients (matched controls), with negative serology for HBV and other viral hepatitides, were matched by age, diagnosis, disease risk, intensity of conditioning regimen, and donor type. In addition, the HBcAb-positive patients and all seronegative patients (all controls, n = 1858) undergoing transplantation during the same period were compared to adjust for other confounding effects. Patient characteristics and baseline hepatic function studies were similar in the HBcAb-positive and matched control groups. The cumulative incidence of hepatitis B reactivation (defined as the emergence of HBsAg in serum) was 11.6% at 3 years. There were no significant differences in overall survival, relapse, nonrelapse mortality, and incidence of acute graft-versus-host disease between the HBcAb-positive and control groups. Our data suggest that seropositivity for HBcAb and seronegativity for HBsAg at the time of transplantation does not seem to adversely affect outcome after allo-HSCT.

Abstract
The risk of viral B and C hepatitis has long been considered to be increased in patients with inflammatory bowel disease (IBD). Blood transfusion and surgery have been identified as the two main risk factors, suggesting nosocomial transmission could be involved. However, recent epidemiologic surveys have found that prevalence in IBD patients is similar to or even lower than that in the general population. Part of the explanation of these recent data may lie in the application of protective measures against viral infection (hepatitis B virus [HBV] vaccination and hepatitis C virus [HCV]-free blood transfusions). Sometimes fatal viral reactivations have been reported in patients on immunosuppressive therapy. Two periods can be distinguished: a) during therapy, a rise in viremia associated with a decrease of immune-mediated hepatic lesions; b) after cessation of therapy, an immune rebound with a destruction of virus-infected hepatocytes. For HBV, preemptive strategy consisting of an antiviral analog is efficient in chronic HBs antigen carriers. For HCV, the impact of immunosuppressive drugs on the natural history is unclear. Most studies report improved comfort although no biopsies were performed before and after immunosuppressive treatment. Physicians managing IBD patients should be aware of the need for screening and institute preventive measures against B and C hepatitis.

Abstract
AIM: To investigate the frequency of occult hepatitis B, the clinical course of hepatitis B virus (HBV) reactivation and reverse seroconversion and associated risk factors in autologous hematopoietic stem cell transplantation (HSCT) recipients.
METHODS: This study was conducted in 90 patients undergoing autologous HSCT. Occult HBV infection was investigated by HBV-DNA analysis prior to transplantation, while HBV serology and liver function tests were screened prior to and serially after transplantation. HBV-related events including reverse seroconversion and reactivation were recorded in all patients.
RESULTS: None of the patients had occult HBV prior to transplantation. Six (6.7%) patients were positive for HBV surface antigen (HBsAg) prior to transplantation and received lamivudine prophylaxis; they did not develop HBV reactivation after transplantation. Clinical HBV infection emerged in three patients after transplantation who had negative HBV-DNA prior to HSCT. Two of these three patients had HBV reactivation while one patient developed acute hepatitis B. Three patients had anti-HBc as the sole hepatitis B-related antibody prior to transplantation, two of whom developed hepatitis B reactivation while none of the patients with antibody to HBV surface antigen (anti-HBs) did so. The 14 anti-HBs- and/or anti-HBc-positive patients among the 90 HSCT recipients experienced either persistent (8 patients) or transient (6 patients) disappearance of anti-HBs and/or anti-HBc. HBsAg seroconversion and clinical hepatitis did not develop in these patients. Female gender and multiple myeloma emerged as risk factors for loss of antibody in regression analysis (P < 0.05).
CONCLUSION: Anti-HBc as the sole HBV marker seems to be a risk factor for reactivation after autologous HSCT. Lamivudine prophylaxis in HbsAg-positive patients continues to be effective.

Abstract
Allogeneic hematopoietic SCT (HSCT) increases the risk of hepatitis B virus (HBV) reactivation in hepatitis B surface antigen (HBsAg) carriers but the incidence, risk factors and course of HBV reactivation after HSCT in HBsAg-negative/anti-hepatitis B core antigen (anti-HBc)-positive recipients are not well known. A total of 50 HBsAg-negative/anti-HBc-positive HSCT recipients with onco-hematological diseases, underwent sequential clinical and laboratory examinations, including serum HBsAg, during follow-up. Serum HBV DNA collected at HSCT was retrospectively amplified by a sensitive PCR assay. During 17 months of follow-up, six (12%) patients had seroreverted to HBsAg, 7-32 months after HSCT, with 1- and 5-year cumulative rates of 13 and 22%. HBsAg seroreversion was associated with serum HBeAg higher than 8 log₁₀ copies per ml HBV DNA and a 1.5 to 36 fold increase of serum alanine aminotransferase leading to HBeAg-positive chronic hepatitis B in all patients. Patients with chronic onco-hematological disease and long-lasting immunosuppression following HSCT had a higher risk of HBsAg seroreversion independently of serum HBV DNA levels at HSCT. HBsAg-negative/anti-HBc-positive HSCT recipients with chronic onco-hematological disease carry a significant risk of HBsAg seroreversion and HBeAg-positive chronic hepatitis B, independently of serum levels of HBV DNA at transplantation.

Abstract
INTRODUCTION Hepatitis B virus (HBV) reactivation is a major cause of morbidity and mortality in patients with hematological malignancies who receive cytotoxic chemotherapy. We have therefore carried out a prospective observational study out to assess the incidence, prevalence, and clinical course ina cohort of these patients. METHODS HBV and HCV markers and liver function indices were monitored prospectively in 318 consecutive patients(171 males, 147 females; mean age 57 years) with hematological malignancies, who had been referred to the Hematology Division, Perugia University, between October 2005 and March 2007 and followed up for at least 6 months. RESULTS At diagnosis, 32 patients (10%) had received HBV vaccination; 30 were responders. At least one HBV marker was positive in 70/318 patients (22%): 14 (20%) were HBsAg-positive(HBV surface antigen-positive), 13 (19%) were only anti-HBc positive (antibodies to HB core antigen), and 43(61%)were anti-HBc and anti-HBs positive. Twelve HBsAg+ patients received nucleoside/nucleotide analogs (adefovir [six patients],lamivudine [four], and combined adefovir/lamivudine[two non-responders to lamivudine]). After 6 months of therapy, HBV-DNA was negative and transaminases were normal in nine of these 12 patients (adefovir [six], lamivudina[two], adefovir + lamivudina [one]). Seroreversion was achieved in 3/13 patients (23%) who were only anti-HBc positive;all were on rituximab therapy and received adefovir. Seroreversion was not observed in any of the 43 patients who were anti-HBc- and anti-HBs positive. CONCLUSIONS Essential to the management of patients with hematological malignancies undergoing chemotherapy are surveillance and prophylaxis of HBV infection together with prompt administration of nucleoside/nucleotide analogs in cases of reactivation and/or seroreversion.

Abstract
BACKGROUND/AIMS The aim of this study was to establish the characteristics of children with hepatitis B e antigens (HBeAg) positive chronic hepatitis B who were cleared of hepatitis B surface antigens (HBsAg) as a result of lamivudine treatment. METHODS Seventy-six children with chronic hepatitis B who were seropositive for HBeAg were treated with lamivudine for at least 6 months. HBeAg seroconversion occurred during treatment in 49 of these children, who were then followed up to assess their clearance of serum HBsAg. Various clinical variables were compared between those patients who were cleared of HBsAg and those who were not, including age, pretreatment serum levels of alanine aminotransferase (ALT) and hepatitis B virus (HBV) DNA, treatment duration, the time elapsed between initiation of treatment and ALT normalization, HBV DNA negativization, HBeAg seroconversion, and HBsAg clearance. RESULTS HBsAg disappeared in 13 of the 49 (26.5%) patients who experienced lamivudine-induced HBeAg seroconversion; HBsAg did not reappear during follow-up period (1-86 months). The time that elapsed between initiation of lamivudine treatment and total HBsAg clearance was 25.9+/-27.1 months (mean+/-SD; range: 5-104 months). The age at which treatment was initiated was the only factor associated with HBsAg clearance. Children who were cleared of HBsAg were significantly younger than those who were not (5.1+/-4.3 years vs. 7.9+/-4.9 years, respectively; P=0.006). All 13 of these patients eventually produced antibodies to HBsAg. CONCLUSIONS Younger children (age <7 years old) have a higher chance of HBsAg clearance than older children after the treatment of HBeAg-positive chronic hepatitis B with lamivudine.

Abstract
BACKGROUND/AIMS This study examined the effects of hepatitis B virus (HBV) infection state and immunologic capability in both the recipients and donors of allogenic hematopoietic stem-cell transplantation (allo-HSCT) on changes in HBV serologic markers in recipients. METHODS A total of 537 patients underwent allo-HSCT for the treatment of leukemia, malignant lymphoma, and solid tumor. HBV serologic markers were examined in both recipients and donors prior to and following the transplantation. The mean follow-up period was 36.6 months (range 3-80 months). RESULTS Of the 537 patients who underwent allo-HSCT, 45 recipients were positive for HBsAg prior to transplantation. Of these 45 patients, 21 were transplanted from anti-HBs-positive donors and the remaining 24 were transplanted from anti-HBs-negative donors. In the former cases, seroconversion was noted in 4 of the 21 patients (19%). In the latter cases, however, no seroconversion was noted following the transplantation. Thirty patients who were negative for both HBsAg and anti-HBs were transplanted from anti-HBs-positive donors, and 15 out of 30 patients (50%) acquired anti-HBs. Four hundred and seven patients who were positive for anti-HBs were transplanted from anti-HBs-positive or HbsAg-negative donors; 8 of these proved HBsAg-positive following the transplantation. There were no changes in HBV serological markers following transplantation in 41 patients who were transplanted from HbsAg-positive donors. CONCLUSIONS Due to the adoptive immunity that was transferred from anti-HBs-positive donors, a seroconversion of HBsAg could occur in some HBsAg-positive recipients. HBsAg-positive donors had a lesser effect on the HBV serologic markers of recipients. However, a reactivation of HBV can occur following hematopoietic stem-cell transplantation in the cases of recipients or donors with a history of HBV, infection by an accompanying immune suppression. Therefore, prevention should be instigated.

Abstract
BACKGROUND & AIMS HBV infection may reactivate in the setting of immunosuppression, although the frequency and consequences of HBV reactivation are not well known. We report 6 patients who experienced loss of serologic markers of hepatitis B immunity and reappearance of HBsAg in the serum as a result of a variety of acquired immune deficiencies. METHODS Between 2000 and 2005, six patients with reactivation of hepatitis B were seen in consultation by the Liver Diseases Branch at the Clinical Center, National Institutes of Health. The course and outcome of these 6 patients were reviewed. RESULTS All 6 patients developed reappearance of HBsAg and evidence of active liver disease after stem cell transplantation (n = 4), immunosuppressive therapy (n = 1), or change in human immunodeficiency virus antiretroviral regimen (n = 1), despite having antibody to HBsAg (anti-HBs) or antibody to hepatitis B core antigen (anti-HBc) without HBsAg before. All 6 patients developed chronic hepatitis B, 2 patients transmitted hepatitis B to their spouses, and 1 patient developed cirrhosis. The diagnosis of hepatitis B reactivation was frequently missed or delayed and often required interruption of the therapy for the underlying condition. None of the patients received antiviral prophylaxis against HBV reactivation. CONCLUSIONS Serologic evidence of recovery from hepatitis B infection does not preclude its reactivation after immunosuppression. Screening for serologic evidence of hepatitis B and prophylaxis of those with positive results by using nucleoside analogue antiviral therapy should be provided to individuals in whom immunosuppressive therapy is planned.

Abstract
Reactivation of resolved hepatitis B virus (HBV) infection has been reported in allogeneic hematopoetic stem cell transplantation (HSCT) recipients, but its epidemiology is not well characterized. We performed a retrospective assessment of the timing and risk factors of HBV reactivation among patients with resolved HBV infection undergoing allogeneic HSCT between January 2000 and March 2008. HBV reactivation was defined as development of positive hepatitis B surface antigen after transplant. Among the 61 patients with resolved HBV infection before transplant (hepatitis B core antibody-positive, hepatitis B surface antigen-negative), 12 (19.7%) developed HBV reactivation. The cumulative probability of HBV reactivation 1, 2, and 4 years after transplant was 9.0%, 21.7%, and 42.9%, respectively. In a time-dependent Cox model, the adjusted hazard ratio (HR) of HBV reactivation for patients with pretransplant hepatitis B surface antibody levels <10 milli-international units per milliliter (mIU/mL) was 4.56 (95% confidence interval [CI] 1.23-16.9) compared to those with levels > or =10 mIU/mL; the adjusted HR among patients who developed extensive chronic graft-versus-host disease (cGVHD) was 7.21 (95% CI 1.25-41.5) compared to those who did not. HBV reactivation is a common late complication among allogeneic HSCT recipients with pretransplant resolved infection. Screening for HBV reactivation should be considered for at-risk HSCT recipients. In this cohort, HBV reactivation often developed in patients with cGVHD. Liver biopsy was useful in those patients with both to delineate the contribution of each to liver dysfunction.

Abstract
OBJECTIVE This study investigates the prevalence of occult hepatitis B virus (HBV) in children and adolescents with haematological diseases with or without hepatitis C virus (HCV) infection. METHODS Forty-nine children with haematological disorders (median age 11.4 years) and 51 with haematological malignancies (median age 8 years) were enrolled. Sera were tested for HCV antibodies, HCV-RNA [nested reverse transcriptase polymerase chain reaction (PCR)], HBV markers (HBsAg, anti-HBcAb IgM and total, HBeAg) and HBV-DNA (nested PCR for s, c and x regions). RESULTS Anti-HCV was detected among 40/49 (81.6%) children with haematological disorders (24/49; 49% HCV-RNA positive) and 9/51 (17.6%) children with malignancies (12/51; 23.5% HCV-RNA positive). HBV-DNA was positive among 38%; positive c region in 33% (15/49 and 18/51 children with haematological disorders and malignancies respectively), s region in four leukaemics and x region in one leukaemic. Twenty-one patients had occult HBV infection; one (2.6%) was HBeAg positive, four (19%) total HBcAb positive, 20 (95.2%) c region HBV-DNA positive and one was s region positive (1/21; 4.8%). HCV-RNA was the significant predictor for occult HBV (P<0.05), with an increased frequency of HBV-DNA in the HBsAg negative (HCV-RNA positive) (63.2%) compared with patients negative for HCV-RNA (25%) (P=0.009). CONCLUSION Occult HBV infection is not uncommon in transfused immunocompromised children with chronic HCV infection. Nucleic acid amplification should be considered in screening donors as post-transfusion hepatitis B viraemia may be substantial.

Abstract
BACKGROUND Occult hepatitis B virus (HBV) infection is characterized by undetectable serum HBV surface antigen (HBsAg) but detectable HBV-DNA in serum or liver. AIMS To determine the prevalence and clinical impact of occult HBV in autoimmune liver diseases as similar data are missing. METHODS One hundred and ninety-six sera samples from HBsAg-negative patients, including 66 autoimmune hepatitis (AIH), 93 primary biliary cirrhosis (PBC) and 37 primary sclerosing cholangitis (PSC), were investigated for HBV-DNA using the polymerase chain reaction (PCR) before treatment initiation. One hundred and three serial samples from 38 AIH patients under immunosuppression and 282 selected blood donors (HBsAg negative; antibodies to HBV-core antigen positive) were also investigated. Fourteen available paraffin-embedded AIH liver samples were also investigated for HBV-DNA by nested-PCR. RESULTS Hepatitis B virus DNA was detected in the serum of 24/196 patients (12.2%) and 0/282 donors (P=0.0000). Nine patients had AIH (13.6%), eight had PBC (8.6%) and seven had PSC (18.9%) (P=0.0000 vs healthy). HBV-DNA detection in AIH livers was higher than in serum. HBV-DNA was associated neither with HBV markers nor with epidemiological, laboratory and clinical data. Serial testing of AIH patients revealed two HBV-DNA-negative patients before treatment becoming positive during treatment, while all HBV-DNA-positive patients before immunosuppression became negative. CONCLUSION Based mainly on serum HBV-DNA, we found a significant proportion of autoimmune liver disease patients with occult HBV compared with donors. However, taking into account our results in a small number of liver tissues, it should be emphasized that occult HBV could be even higher when both serum and liver specimens are investigated. Occult HBV does not seem to affect the clinical and laboratory features of the diseases, while AIH patients with occult HBV under immunosuppression do not deteriorate during follow-up.

Abstract
It is generally accepted that seroconversion of hepatitis B virus (HBV) surface antigen (HBsAg) to an antibody to HBsAg (anti-HBs) indicates clearance of HBV. Here we report a case of severe hepatitis that manifested during chemotherapy in a female patient with chronic lymphocytic leukemia (CLL) who had been initially seronegative for HBsAg and seropositive for anti-HBs. The patient received chlorambucil and prednisolone for the treatment of CLL. After 6 months the serum levels of aminotransferases were increased, and HBsAg and HBV DNA were present in serum. Lamivudine was administered immediately after confirming the HBV reactivation, which considerably improved jaundice and aminotransferase levels after 3 weeks. The patient was able to resume the chemotherapy whilst continuing lamivudine treatment. This case report highlights the need for physicians to be aware of the potential risk of HBV reactivation even in an HBsAg-negative person but with detectable anti-HBc and/or anti-HBs, underscoring the need for future studies that explore the role of antiviral prophylaxis in this setting.

Abstract
Hepatitis B virus (HBV)-reverse seroconversion (RS) following allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a frequent late-onset complication in recipients with previous HBV infection. We followed 38 allo-HSCT recipients with previous HBV infection, and conducted posttransplant HB vaccine intervention in 13 recipients. First, we followed the recipients without any intervention (historic control) until 2003; hence, we commenced HB vaccination. Out of the patients who underwent transplantation after 2003, 13 recipients were immunized by a standard three-dose regimen after immunosuppressant cessation (vaccine group), whereas 12 recipients were observed without any intervention (nonvaccine group). Eight of the 13 historic control group recipients and 3 of the 12 nonvaccine group recipients, but none of the 13 vaccine group recipients, suffered HBV-RS. Cumulative risks of HBV-RS at 3 years post-HSCT in the historic control, nonvaccine and vaccine groups were 41%, 39%, and 0% respectively (P=.022). We therefore conclude that intervention with HB vaccines is significantly effective in preventing post-HSCT HBV-RS.

Abstract
Complete characterization of the biological properties of hepatitis B virus (HBV) variants requires the generation of full-length genomes. The aim of this study was to develop new tools for the efficient full-length genome amplification of virus from samples with low viral loads. Rolling circle amplification (RCA) was used to amplify full-length HBV genomes from both sera and liver biopsy samples from chronic HBV carriers. Serum-derived relaxed circular HBV DNA could be amplified only after completion and ligation of plus-strand DNA. Covalently closed circular DNA (cccDNA) from liver biopsies could be amplified directly from as few as 13 copies, using RCA, followed by a full-length HBV PCR. Three serial liver biopsy samples were obtained from a lamivudine-resistant patient who cleared detectable serum HBV after adefovir dipivoxil was added to the lamivudine therapy and then seroconverted to anti-HBs. Only the genomes from the last biopsy specimen obtained after the emergence of lamivudine resistance contained the lamivudine resistance-associated mutations rtL180M and rtM204V ("rt" indicates reverse transcriptase domain). Defective genomes were also found in this biopsy sample. Genomes cloned from the liver biopsy specimens were transfected into HuH7 cells to study their replication competence and their susceptibility to lamivudine. RCA is a powerful tool for amplifying full-length HBV genomes and will be especially useful for the study of occult or inactive HBV infections and patients undergoing antiviral treatment. It can also be used to probe HBV cccDNA, the crucial intermediate in viral persistence and the archive of resistance mutations.

Abstract
Reactivation of viral hepatitis B is a well-known complication in patients receiving chemotherapy or immunosuppressive therapy; its incidence reaches 50%. This reactivation is associated with a high rate of morbidity and mortality. Prophylactic treatment of viral reactivation with lamivudine resulted in lowering the incidence of this risk and improving prognosis in recent studies. Patients with hematological malignancies and other cancers require a precise assessment of their hepatitis B status and adequate management. There is not yet a consensus about the appropriateness of prophylactic treatment of occult hepatitis B infection or of pretreatment virologic assessment, especially measurement of viral DNA.

Abstract
Viral hepatitis is the third major cause of liver dysfunction in allogeneic transplant recipients and has become a significant concern in patients with hematological malignancies receiving chemotherapy. Thus, identification of patients at risk for viral hepatitis is very important when evaluating and treating hematological malignancies. Serologic screening for all patients should include anti-HCV, hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (anti-HBs), and hepatitis B core antibody (anti-HBc) testing. Current therapies for hepatitis B (HBV) virus infection are aimed at viral suppression, while treatment for hepatitis C (HCV) virus can eradicate infection in many treated patients. To prevent HBV viral reactivation, prophylaxis with nucleoside analogues should be initiated for all HBsAg-positive patients. HCV infection appears to have little impact on short-term survival after bone marrow transplantation (BMT), but eventually can impact long-term survival due to progression of liver disease. In this review we will highlight the mechanisms of virus reactivation, clinical manifestations, and management strategies to minimize acute and chronic morbidity in this population.

Abstract
Hepatitis B virus (HBV) is a highly pathogenic virus that causes chronic liver diseases in millions of people globally. In addition to a symptomatic, serologically evident infection, occult persistent HBV carriage has been identified since nucleic acid amplification assays of enhanced sensitivity became introduced for detection of hepadnaviral genomes and their replicative intermediates. Current evidence indicates that occult HBV infection is a common and long-term consequence of resolution of acute hepatitis B. This form of residual infection is termed as secondary occult infection (SOI). The data from the woodchuck model of HBV infection indicate that exposure to small amounts of hepadnavirus can also cause primary occult infection (POI) where virus genome, but no serological makers of exposure to virus, are detectable, and the liver may not be involved. However, virus replicates at low levels in the lymphatic system in both these forms. We briefly summarize the current understanding of the nature and characteristics of occult hepadnaviral persistence as well as of its documented and expected pathological consequences.

Abstract
The prevalence of hepatitis B virus (HBV) infection in patients with haematological malignancies is increased compared with the general population worldwide. HBV reactivation is common following chemotherapy and is associated with a high mortality despite prompt anti-viral treatment. HBV reactivation may necessitate interruption of chemotherapy with adverse prognostic consequences for the haematological disease. Chemotherapy-induced immune suppression may lead to increased HBV replication. Immune reconstitution within the weeks and months following recovery from chemotherapy may be associated with a flare of hepatitis B manifested by hepatocellular injury. Risk factors associated with HBV reactivation include detectable hepatitis B surface antigen (HBsAg), HBV DNA, Hepatitis B e (HBeAg) antigen, antibodies to hepatitis B core antigen (anti-HBc), treatment with corticosteroids, young age and male gender. Lamivudine is effective during HBV reactivation due to immune suppression. Clinical trials have demonstrated that pre-emptive antiviral treatment with lamivudine is superior to deferred treatment. Current recommendations emphasise screening for HBV infection in all haematology patients, particularly prior to chemotherapy. Patients who are HBsAg positive or HBV DNA positive should receive pre-emptive treatment with lamivudine before chemotherapy. The duration of lamivudine treatment may be prolonged commensurate with the degree of immunosuppression. HBV naïve patients should be immunised against hepatitis B, as should haematopoietic stem cell donors. In summary, overt and occult HBV pose a serious, but preventable, threat. Pre-treatment screening of patients at risk should be practiced diligently by all clinicians that treat patients with malignancies.

Abstract
There is little information in literature about the use of hepatitis B immunoglobulin (HBIg) in recipients of bone marrow transplantation (BMT). Here, we report two children who received IV HBIg (Hepatect-CP) and lamivudine treatment during BMT course for either patient or donor hepatitis B virus (HBV) viremia. A four-year-old girl underwent a fully human leukocyte antigen-matched allogeneic BMT for thalassemia major from her mother positive for hepatitis B surface antigen (HBsAg). A 12-yr-old boy with chronic myeloid leukemia, positive for HBsAg and HBV-DNA received a fully HLA-matched allogeneic BMT from his sister in the first chronic phase of the disease. HBIg was successfully used in both cases to prevent HBV reactivation of the recipients. The results of our observations are encouraging and we suggest that HBIg in combination with lamivudine may be used in such cases especially in post-transplant early period to prevent HBV reactivation.

Abstract
Under immunosuppressive conditions after hematopoietic stem cell transplantation (HSCT), even if hepatitis B virus (HBV) antigen is negative but hepatitis B surface antibody (HBsAb) or hepatitis B core antibody (HBcAb) is presented, HBV reactivates and sometimes causes fulminant hepatitis. However, it remains unclear which patients will develop fulminant hepatitis, or whether fulminant hepatitis is caused by host-related factors or by virus-related factors. A 30-yr-old man with a history of aplastic anemia since 3 yr of age underwent allogenic BMT, when HBsAb and HBcAb were positive but HBs antigen (HBsAg) was negative. The donor was negative for HBsAg, HBsAb and HBcAb. After transplantation, the patient was complicated by acute graft-vs.-host disease (GVHD), cytomegalovirus infection, intestinal thrombotic microangiopathy and aspergillus colitis. Chronic GVHD was well controlled by FK506 and prednisolone. Twenty months after transplantation, the patient was admitted with general fatigue and liver dysfunction and was found to be positive for HBsAg and HBeAg. His serum HBV-DNA level was >8.8 log of the genome equivalent (LGE)/mL. Therefore, he was diagnosed as having hepatitis B caused by HBV reactivation and 100 mg/d lamivudine treatment was started. However, jaundice and hepatic failure deteriorated and became fatal. On analysis of the HBV-DNA, two adjacent gene mutations in the core promoter region (T1762/A1764) were detected. Increased replication of the mutated HBV might have caused HBV reactivation which progressed to fulminant hepatitis.

Abstract
AIM: To study the prevalence and clinical effects of occult HBV infection in haemodialysis patients with chronic HCV.
METHODS: Fifty chronic hemodialysis patients with negative HbsAg, and positive anti-HCV were included in the study. These patients were divided into two groups: HCV-RNA positive and HCV-RNA negative, based on the results of HCV-RNA PCR. HBV-DNA was studied using the PCR method in both groups.
RESULTS: None of the 22 HCV-RNA positive patients and 28 HCV-RNA negative patients revealed HBV-DNA in serum by PCR method. The average age was 47.2 ± 17.0 in the HCV-RNA positive group and 39.6 ± 15.6 in the HCV-RNA negative group.
CONCLUSION: The prevalence of occult HBV infection is not high in haemodialysis patients with chronic HCV in our region. This result of our study has to be evaluated in consideration of the interaction between HBsAg positivity (8%-10%) and frequency of HBV mutants in our region.

Abstract
HBV infection in the absence of HBsAg has been a matter of debate for years, but its existence and clinical relevance are now supported by many publications, editorials and reviews. HBV DNA without HBs antigenemia was detected in the following clinical situations: (1) Chronic, presumably viral, hepatitis unrelated to HCV, atypical alcoholic hepatitis and hepatocellular carcinoma (HCC); (2) viral reactivation following immunosuppression; (3) Transmission through transplantation, transfusion or experimental transmission to chimpanzees. Occult HBV infections are not restricted to areas of high HBV endemicity. Indeed, such cases have been described in Western countries including France. It is now established that occult HBV infection among non-HCV patients suffering from chronic hepatitis varies from 20% to 30% in Europe, and in the context of HCV infection it varies from 20% in France up to 80% in Japan. The percentage of occult HBV infections among non A-E cases depends on several parameters: (1) The method of detection, including PCR primer selection; (2) patient recruitment; (3) patients from countries highly endemic for HBV are more likely to develop occult HBV infections; (4) prevalence may also vary depending on the nature of biological material tested, with a higher proportion for liver compared to serum specimen. The mechanisms leading to HCC in occult HBV infection seem similar to those overt cases, patients with low-grade but diagnosable HBV replication that retains its pro-oncogenic properties. During the course of HCV infection, occult HBV infection may worsen liver damage induced by HCV and reduce the response to HCV antiviral treatment. Occult HBV infection is a frequent phenomenon and HBV DNA testing with highly sensitive PCR in the clinical setting is therefore becoming of paramount importance.

Abstract
AIM: To analyze whether the presence of anti-HBs in liver transplant recipients is effective in preventing HBV infection.
METHODS: Twenty-three patients receiving anti-HBc positive liver were studied. Nine recipients were anti-HBc positive as a result of previous HBV infection. Of them, one also received HBV vaccine during the pre-liver transplantation period. Fourteen recipients were anti-HBs positive due to HBV vaccine administered during the pre-transplant period. Liver biopsy was obtained in 10/14 anti-HBc negative/anti-HBs positive recipients and in 4/9 anti-HBc positive recipients.
RESULTS: After a mean follow-up period of 46 months, 1 recipient with protective serum anti-HBs levels developed de novo HBV infection as a consequence of immune escape HBV mutants. Among the 14 vaccinated anti-HBc negative/anti-HBs positive recipients, 1/10 patients with available liver biopsy (10%) had liver HBV-DNA at 13 mo post-liver transplantation without serum viral markers and did not develop de novo HBV infection. The vaccinated anti-HBc positive recipient without HBV vaccine response was HBV-DNA positive in serum and liver, viral DNA was continuously negative in the following tests, so a spontaneous seroconversion was diagnosed.
CONCLUSION: The presence of anti-HBs as a result of HBV vaccine or past HBV infection seems to be effective at protecting patients receiving livers from anti-HBc positive donors. However, the emergence of immune escape HBV mutants, which can evade the anti-HBs protection, should be considered as a risk of HBV infection.

Abstract
BACKGROUND Reactivation of hepatitis B virus (HBV) infection following allogeneic bone marrow transplantation is a rare phenomenon. METHODS Reverse seroconversion, defined as the clearance of antibody to hepatitis B surface antigen (HBsAb) and the appearance of hepatitis B surface antigen (HBsAg) in a patient with resolved HBV infection (i.e., a HBsAg-negative, HBsAb-positive, hepatitis B core antibody-positive patient) following receipt of a bone marrow transplant is described. A review of related cases in the literature was undertaken to identify clinical features associated with this phenomenon. RESULTS We present a case of reactivation of HBV infection in a 47-year-old man after receipt of an allogeneic bone marrow transplant for acute myelogenous leukemia. Before undergoing bone marrow transplantation, the presence of HBsAb and hepatitis B core antibody and the absence of HBsAg indicated clearance of natural HBV infection. The donor was HBsAg and HBsAb negative. Twenty-nine months after bone marrow transplantation, the patient developed transaminitis and evidence of active HBV infection (the patient had test results positive for HBsAg, negative for HBsAb, and positive for HBV DNA). A total of 28 other cases of reverse seroconversion have been described in the literature, 11 of which provided adequate information to be summarized in detail together with the present case. Reactivation of HBV infection following bone marrow transplantation appears to occur almost exclusively in patients who have received marrow from an HBsAb-negative donor and have experienced graft-versus-host disease, the onset of which is associated with tapering of immunosuppressive therapy. CONCLUSIONS Although HBV reverse seroconversion is an uncommon event, understanding the clinical features associated with the development of HBV reverse seroconversion may provide insight into how such a potentially fatal complication may be avoided.

Abstract
We evaluated clinical evolution and hepatitis B virus (HBV) molecular changes in heart recipients with chronic HBV infection before transplantation, and studied the effects of lamivudine treatment in patients who experienced HBV reactivation. Nine patients with chronic HBV infection who underwent heart transplantation were investigated. HBV surface/core-promoter/precore/core regions were sequenced. Prior to transplantation, all nine patients had consistently normal ALT and low HBV-DNA levels. Seven experienced HBV reactivation after transplantation (ALT elevated, HBV-DNA>200.000 cps/ml). Lamivudine treatment was initially effective in all patients; three patients during the second year of treatment developed lamivudine resistance-associated mutations (rt-L180M, rt-M204V) with severe disease reactivation, remitted after switch to adefovir treatment. No other significant HBV mutations were identified in the genomic regions studied. Immune suppression is crucial in the reactivation of previous inactive HBV infection and in the liver disease progression in heart recipients. Preemptive lamivudine treatment could be useful in the early management of these patients.

Abstract
In the absence of prophylaxis, the reactivation of hepatitis B in oncology patients who are hepatitis B carriers is a well-known and often fatal complication of chemotherapy. The current recommendations in Canada and the USA are that patients who are positive for hepatitis B surface antigen (HBsAg) receive antiviral prophylaxis prior to chemotherapy. We report a 67-year-old man with B-cell lymphoma who developed hepatitis B reactivation following chemotherapy with cyclophosphamide, adriamycin, vincristine, prednisone and rituximab. Pre-chemotherapy, the patient was negative for HBsAg, positive for hepatitis B core antibody (anti-HBc) and weakly positive for hepatitis B surface antibody. Despite treatment with lamivudine, the patient died of fulminant hepatic failure. Our experience indicates that patients who are negative for HBsAg but positive for anti-HBc are still at risk for reactivation of latent hepatitis B during and after chemotherapy and may be considered for prophylaxis.

Abstract
The biological properties of latent or occult hepatitis B virus (HBV) have been poorly characterized as a result of the extremely low virus concentration. This report describes the phenotype of HBV reactivating in two patients after an HBsAg-negative latency period. One patient had latent HBV infection for at least 12 years without detectable viremia and symptoms of liver disease. Several full-length HBV genomes were cloned at reactivation, sequenced, and functionally tested by transfection into HuH7 cells. Genomes from both patients showed a low replication phenotype. It was caused at the level of RNA encapsidation or HBV DNA synthesis, but was not attributable to uncommon mutations in the terminal protein domain of P protein. A substantial subpopulation ( approximately 50%) of genomes from one patient did not express pre-S2/S mRNA and HBsAg. Site-directed mutagenesis identified a single G-A mutation within the S gene (position 458) to be responsible for this effect. The G458A mutation was also effective if the S gene was placed under control of a heterologous promoter. Furthermore, nuclear run-on transcription showed that the G458A mutation acts at the posttranscriptional level. The mutation affected a 5' splice site and prevented splicing of the pre-S2/S mRNA from position 458 to 1305. In conclusion, HBV latency may be characterized by viruses with reduced replication competence and antigen expression. In one patient, HBsAg expression was terminated by an as yet undescribed posttranscriptional mechanism. A single mutation inactivated a 5' splice site that is obviously essential for pre-S2/S mRNA accumulation.

Abstract
BACKGROUND/AIMS Hepatitis B virus (HBV) infection in extrahepatic tissues is controversial. To clarify whether episomal HBV can infect nonhepatic tissues, we investigated the molecular forms of HBV in the lymphatic cells of inactive HBV carriers who lacked viremia, thus avoiding contamination with HBV genomes originating from the viral particles present in the serum. METHODS We assessed HBV genome, replicative forms, and viral integrants in the liver, serum, peripheral blood mononuclear cells (PBMC), and lymph nodes of 21 inactive HBV carriers who tested positive for antibodies against the HBV core antigen (anti-HBc). RESULTS Of the 21 anti-HBc positive individuals, HBV-DNA was detected in liver samples of 15 (71.4%), in the lymph nodes of 11 (52.4%), and in PBMC of three (14.3%). However, none of the detected HBV genomes from lymphatic tissues included the replicative forms of HBV. In one case, integrated HBV was present in the lymphatic tissues and the host-viral junction was present in the intronic sequences of chromosome 17. CONCLUSIONS These data suggest that human lymphatic tissues cannot support viral replication in anti-HBc positive inactive HBV carriers, while retaining the viral genome as an integrated form.

Abstract
BACKGROUND/AIMS The acquisition of hepatitis B virus (HBV) infection following organ transplantation from donors with occult HBV infection is an important cause of morbidity and mortality. The aim of this study is to determine the prevalence of occult HBV in allogeneic hematopoietic stem cell (HSC) transplantation donors. METHODS We performed a retrospective study on 124 consecutive hepatitis B surface antigen negative HSC donors. Their serum samples were analyzed by PCR for the pre-S/S, pre-core/core and X regions of the virus. Samples reactive by at least two PCR assays were considered HBV-DNA positive. RESULTS Nineteen of the 124 HSC donors (15.3%) had occult HBV infection. Sixteen of these 19 donors with occult HBV infection (84.2%) tested positive for hepatitis B core antibody while 78 of 105 subjects (74.3%) without occult HBV infection were also positive (P=0.56). Fourteen of the 19 donors (73.7%) with occult HBV infection tested positive for hepatitis B surface antibody while 67 of the 105 subjects without occult HBV infection were also positive (P=0.45). CONCLUSIONS The prevalence of occult HBV infection among HSC donors in Hong Kong is high. Anti-HBc and anti-HBs status had no significant correlation with the presence of occult HBV infection.

Abstract
Reactivation of resolved hepatitis B virus (HBV) infection, which is known as reverse seroconversion (RS), has been reported as a rare complication of allogeneic hematopoietic stem cell transplantation. We retrospectively studied HBV serologic markers in 14 recipients with pretransplant anti-hepatitis B surface antigen antibody (anti-HBs). Progressive decreases in anti-HBs titer were observed in all cases. In 12 cases, anti-HBs titer had decreased to under the protective value. RS occurred in seven cases after disappearance of anti-HBs. Although reseroconversion occurred in five cases, two cases remained in an HBV-carrier status after resolution of hepatitis. In the other five cases, RS did not occur even after disappearance of anti-HBs. The actual risks of anti-HBs disappearance and RS were estimated to be 75.0% and 39.8% at 2 years and 100.0% and 70.0% at 5 years, respectively. In conclusion, RS is a late-onset complication with high frequency that can be predicted by careful monitoring of progressive decrease in anti-HBs titer.

Abstract
Hepatitis B virus (HBV) reactivation after allogeneic haematopoietic stem cell transplantation (allo-HSCT) is well known in HBsAg-positive carriers but has only occasionally been reported in patients with resolved HBV infection. We investigated six allo-HSCT recipients with pretransplant anti-HBs and anti-HBc antibodies for serologic markers of HBV infection and for the presence of HBV-DNA in serum. Reverse seroconversion, that is, reappearance of HBsAg after a gradual loss of anti-HBs, but no severe liver damage was observed in three patients at 14, 22 and 12 months after HSCT, respectively. There was an increase in HBV-DNA concentration prior to reverse seroconversion. One patient was repeatedly HBV-DNA positive (10(2)-10(3) copies/ml) without reverse seroconversion. Sequencing of the HBsAg and precore region derived from the four HBV-DNA-positive patients showed no relevant mutations. In conclusion, this study demonstrated a high risk (50%) of reverse seroconversion in allo-HSCT recipients with resolved HBV infection. A highly sensitive HBV-DNA assay (TaqMan-PCR) allowed early identification of the individual patients at risk.

Abstract
BACKGROUND Hepatitis B virus (HBV) DNA often remains detectable in serum despite clinical recovery and loss of HBsAg. OBJECTIVE To study whether coinfection with HIV and HCV influence the chance of detecting HBV DNA in sera with markers of past hepatitis B. STUDY DESIGN AND RESULTS The test panel included 160 anti-HBc-positive/HBsAg-negative sera collected in the diagnostic setting. The following parameters were determined in the sera: anti-HIV (32% positive), anti-HCV (34% positive), HCV RNA (18% positive), and anti-HBs (37% positive). A highly sensitive PCR (90%-detection limit 100 copies/ml) amplifying the terminal protein (TP) region of HBV was established and HBV DNA was detected in 12.5% of the samples. In 70% of these samples, the HBV DNA concentration was below 500 copies/ml as measured by real-time PCR in the S gene. Logistic regression analysis revealed that the chance of detecting HBV DNA was increased by a positive HCV serostatus (odds ratio 5.0, 95%-CI 1.6-15.7), whereas HIV coinfection (odds ratio 2.0, 95%-CI 0.7-5.8), anti-HBs (odds ratio 0.9, 95%-CI 0.3-2.6), and HCV RNA status (odds ratio 0.4, 95%-CI 0.1-1.7) had no statistically significant influence. In contrast, the chance of detecting HCV RNA in the subgroup of anti-HCV-positive sera was increased by HIV coinfection (odds ratio 4.5, 95%-CI 1.2-17.4). Sequencing of the TP PCR products revealed neither a specific phylogenetic origin of the circulating HBV DNA nor clustering of uncommon mutations in the TP region. CONCLUSIONS The prevalence of HBV DNA in serum of anti-HBc-positive/HBsAg-negative subjects correlates with HCV rather than HIV serostatus.

Abstract
We report a 38-yr-old male with acute lymphocytic leukemia (ALL), whose serological tests for the hepatitis B virus (HBV) before transplantation showed a chronic carrier status, and a liver biopsy specimen revealed chronic liver injury because of HBV. The patient underwent allogeneic peripheral blood stem cell transplantation (PBSCT) from his sibling who was hepatitis B surface antibody (HBsAb) positive. He had received lamivudine treatment for the prophylaxis of HBV reactivation during cytotoxic chemotherapy, and lamivudine administration continued after transplantation. Successful engraftment was documented 3 wk after PBSCT, and clearance of the hepatitis B surface antigen (HBsAg) was observed 2 months after PBSCT. Liver function tests transiently showed a mild elevation of aminotransferases on day 25, although this returned to normal after the dose escalation of the immunosuppressive agent. We presume that the combination of adoptive immunity transfer by bone marrow transplantation (BMT) from an HBsAb-positive donor and antiviral drugs such as lamivudine is beneficial in clearing HBV in chronic carriers.

Abstract
Hepatitis due to reactivation of hepatitis B virus is an important cause of liver-related morbidity and mortality in hepatitis B surface antigen (HBsAg) positive patients undergoing autologous hematopoeitic cell transplantation. With the recent introduction of sensitive serum HBV DNA quantitation assay, the diagnosis of hepatitis B reactivation can now be made more reliably. As these hepatitis are driven by the host immune response to a surge of hepatitis B viral load, the availability of effective nucleoside analogues which can inhibit hepatitis B viral replication has opened up new approaches to this previously untreatable condition. Up till now, two such nucleoside analogues, lamivudine and adefovir dipivoxil, have been approved for the treatment of chronic hepatitis B infection. However, further studies are needed to determine which nucleoside analogues should be chosen in this transplant setting. Due to the high dose chemotherapy generally needed in autologous hematopoeitic cell transplantation, there is a high risk of post-transplant hepatitis B reactivation. Hence, all HBsAg positive patients undergoing autologous hematopoeitic cell transplantation should preferably be treated pre-emptively with nucleoside analogous. An alternative approach is to defer treatment with nucleoside analogous until there is evidence of hepatitis B virological reactivation. However, the latter approach would need the patient's hepatitis B viral load be monitored at a very close interval and might not be cost-effective.

Abstract
A case of hepatitis B virus (HBV) reactivation after kidney transplantation is reported. The presence of antibodies against hepatitis B surface antigen (HBsAg) and hepatitis B core antigen (HBcAg) before transplantation indicated previous infection with HBV. Eight years after transplantation, a diffuse, large B-cell lymphoma occurred, and the patient was positive for HBsAg and hepatitis B e antigen, in association with normal activity of serum aminotransferases. Postmortem liver histology did not show any sign of portal tract or lobular inflammation despite the presence at immunostaining of extensive intranuclear and cytoplasmic positivity for HBcAg, indicating active viral replication. Natural immunity to HBV may not protect against reactivation in patients with a suppressed immune system. In this setting, periodic follow-up of HBV serology in patients at highest risk for HBV reactivation to allow for early diagnosis and prompt treatment with lamivudine is highly recommended.

Abstract
Despite preventive measures, patients who have cancer or who undergo bone marrow transplantation remain at higher risk of viral infection since they often receive multiple blood products. This category of patients also includes subjects from countries that are highly endemic for hepatitis B virus and hepatitis C virus infection and who travel to developed countries for specialized treatment. This review discusses the current opinions concerning the diagnostic, clinical, and therapeutic aspects of hepatitis B and C virus infection in different groups of patients: children with chronic infection before chemotherapy, children infected during chemotherapy or bone marrow transplantation, and patients with chronic infection after the end of treatment.
