Abstract
BACKGROUND Leukemia patients are immune-compromised even before starting chemotherapy because the malignant cells invade the bone marrow and destroy WBC precursors. Leukemic patients are more susceptible to infection by a wide range of microorganisms. Viral infections and reactivations are common and may result in severe complications. The aim of this study is to investigate different causes of viremia in ALL pediatric patients as well as the clinical and the laboratory characteristics associated with viral infections. METHODS Qualitative real-time PCR was used to detect (polyoma BK, parvo B19 and herpes simplex virus) DNA in the blood of ALL patients and routine hospital records were used to provide the data of hepatitis B & C virus infection. RESULTS Polyoma BK was the most common detected virus (51.2%) followed by herpes simplex (30.2%). Viremia by single virus was found in 16 (37.2%) cases, while viremia by multiple viruses was found in 15 (34.8%) cases. The most frequent co-detected viruses were herpes simplex and polyoma BK (11.6%) followed by herpes simplex, parvo B19 and polyoma BK (9.3%). CONCLUSION There is a high frequency of viremia by single virus and viremia by multiple viruses at the time of diagnosis of acute lymphoblastic leukemia in pediatric patients admitted to South Egypt Cancer Institute (SECI) compared to studies in other regions. Polyoma BK is the most common detected virus and is mainly associated with lymphopenia. It was also significantly associated with herpes simplex viremia. HCV infection was associated with increased incidence of CNS leukemia.

Abstract
Hepatitis B reactivation (HBVr) in cancer patients is a well-established complication due to chemotherapy-induced immunosuppression. Studies have reported HBVr associated with immunosuppressive medications, such as rituximab, methotrexate, and high dose steroids. There are different risks for different types of chemotherapy with rituximab carrying one of the highest risks for hepatitis B reactivation. Tyrosine kinase inhibitors (TKIs) are the standard of care in patients with chronic myeloid leukemia (CML). The risk of HBVr in chronic myeloid leukemia has been reported in many studies, but to this date, there are no clear guidelines or recommendations regarding screening and monitoring of HBV in CML patients receiving TKIs. We conducted this review to identify the risk of HBVr in patients with CML who are treated with tyrosine kinase inhibitors. We recommend testing for HBV status in patients who are to be treated with TKIs and to consider giving prophylaxis in those who are positive for HBsAg at baseline. More studies are needed to assess the risk of reactivation in patients with Hepatitis B core antibody positive receiving TKIs. Currently, monitoring such patients for reactivation may be the best strategy.

Abstract
Hematopoietic stem cell transplantation (HSCT) is a risk factor for viral hepatitis reactivations because it affects lymphocyte number and functions. Latent hepatitis B virus (HBV) may stay in dormant form in hepatocytes and may be reactivated in prolonged immunosuppression. This study analyzes the incidence of reactivation of HBV infections in HSCT patients in a middle endemic country like Turkey. Five hundred and sixty-one HSCT patients from 1994 to 2015 were retrospectively evaluated. Sixty-six patients had a serologic feature of HBV infection. Fifteen patients were hepatitis B surface antigen (HBsAg)-positive patients (3 allogeneic and 12 autologous) while 51 of them were anti-hepatitis B core IgG (anti-HBc IgG)-positive patients (22 allogeneic and 29 autologous). Although under lamivudine prophylaxis, reactivation was seen in three of 12 (25%) chronic HBV (HBsAg positive) patients who received autologous HSCT and in two of the three HBsAg-positive patients who received allogeneic HSCT. Rate of reactivation in the whole HBsAg-positive group was 33%. Reactivation occurred on median 270th day (range: 60-730). Reverse seroconversion incidence was 10% on 133th day for HBsAg negative, but anti-HBc IgG-positive patients, which increased to 17% on 360th and to 23% on 1500th day. Cumulative incidence increased to 41% on 2280th day for isolated anti-HBc IgG-positive patients. Hepatitis B surface antibodies (anti-HBs) were found to be protective as reactivation did not exceed 11% on 5050th day when anti-HBs was positive. When anti-HBc IgG-positive cases were analyzed according to their transplantation types, allogeneic HSCT was found to have higher cumulative incidence (45% on 3258th day) for HBV reactivation than autologous HSCT (7% on 5050th day). Besides, HBV reactivation in anti-HBc IgG-positive patients who received allogeneic transplantation was related to mortality. Findings of this study suggest that HBV prophylaxis extending over 1 year should be prescribed for HBsAg-positive patients independent of the transplantation type. Prophylaxis should also be given to anti-HBc IgG-positive patients if an allogeneic HSCT is to be performed.

Optimal timing of antiviral therapy for patients with malignant tumor who presented with hepatitis B reactivation during chemotherapy and/or immunosuppressive therapy. J Cancer 2020; 11:3559-3566. [PMID: 32284752 PMCID: PMC7150462 DOI: 10.7150/jca.40154] [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: 09/10/2019] [Accepted: 02/22/2020] [Indexed: 11/05/2022] Open
Abstract
Background: Hepatitis B virus (HBV) reactivation may occur with chemotherapy and/or immunotherapy. Antiviral prophylaxis is recommended for all patients who are hepatitis B surface antigen (HBsAg)-positive during chemotherapy and/or immunosuppressive therapy. However, the optimal timing of antiviral therapy before chemotherapy and/or immunosuppressive therapy is not fully elucidated. Patients and methods: We retrospectively evaluated 446 HBsAg-positive patients who underwent chemotherapy and/or immunosuppressive therapy. The cumulative rates of HBV reactivation were evaluated using the Kaplan-Meier method and were compared using the log-rank test. The risk factors of HBV reactivation were examined via univariate and multivariate analyses using the Cox proportional hazards model. Results: The cumulative HBV reactivation rates of patients who received antiviral therapy before chemotherapy and/or immunosuppressive therapy were significantly lower than those of patients who received antiviral therapy after chemotherapy and/or immunosuppressive therapy (P = 0.002). The incidence of HBV reactivation was significantly different between patients who received antiviral therapy at least 1 day before chemotherapy and/or immunosuppressive therapy and those who did not (P = 0.006). No significant difference was observed in the HBV reactivation rates between patients who received antiviral therapy at least 2 days (P = 0.310), 3 days (P = 0.494), and 1 week (P = 0.655) before chemotherapy and/or immunosuppressive therapy and those who did not. The multivariate Cox proportional hazards model showed that women had a lower risk of developing HBV reactivation than men (P = 0.025). The use of the prophylactic antiviral agent entecavir, compared with lamivudine and telbivudine, was associated with the decreased risk of developing HBV reactivation (P = 0.002). Conclusion: HBsAg-positive patients who received preemptive antiviral therapy after chemotherapy and/or immunosuppressive therapy had a high risk of developing HBV reactivation. However, it is not necessary for patients to receive antiviral therapy at least 1 week before chemotherapy and/or immunosuppressive therapy.

Abstract
BACKGROUND Hepatic complications are a well-known cause of both early and late mortality and morbidity in hematopoietic stem cell transplant (HSCT) recipients. Early diagnosis and management of hepatic complications is important in order to commence appropriate therapy. Conditioning regimens, acute and chronic graft versus host disease, sinusoidal obstruction syndrome, and infections among others represent major hepatic complications for the transplant recipient. We assessed liver function tests, viral markers, polymerase chain reaction, abdominal ultrasound, portal, and hepatic venous duplex in 88 patients underwent autologous and 102 patients underwent allogeneic transplant as well as liver biopsy in selected patients in this retrospective study and evaluated early and late hepatic complications and their impact on transplant outcome. RESULTS The major cause of hepatic injury in allogeneic patients is the conditioning regimen (38.8%) followed by acute GVHD (14.7%), after day +100 chronic hepatic GVHD is the primary cause of liver injury which occurred in about 40% of allogeneic patients. In autologous patients, the first cause of hepatotoxicity is also conditioning regimen involving 27.9% of patients followed by flare of viral hepatitis in 7.9% and sepsis in 6.3% of cases. The prevalence of HCV, HBV, and CMV is 19%, 16%, and 8%, respectively. CONCLUSION In our study, conditioning regimens, acute and chronic hepatic GVHD are frequent causes of hepatic injury following allogeneic HSCT while conditioning regimens, flare of viral hepatitis, and sepsis represent the most common causes of hepatic injury following autologous HSCT.

Abstract
PURPOSE OF REVIEW Patients with inflammatory bowel disease (IBD) are at increased risk of infectious diseases independent of their immunosuppression status, and yet, studies suggest that this population is not receiving standard vaccinations at the same rate as the general population. This review seeks to understand why IBD patients may not be receiving recommended immunizations and to provide guidelines on vaccinating this vulnerable population. RECENT FINDINGS Inactive vaccines are recommended for patients with IBD regardless of immunosuppression status due to the increased risk for many vaccine-preventable illnesses. Certain live vaccines can be administered to the immunocompromised patient with IBD. Additionally, many patients with IBD will be immunosuppressed some time in their disease course, further increasing their risk for infection. Despite this understanding, patients with IBD have poor vaccination rates. Inadequate knowledge, limited time with patients, and lack of consensus as to who is responsible for identifying and administering vaccinations are some of the most important barriers to vaccinating the patient with IBD. In this review, we discuss guidelines for vaccinating both the immunocompetent and immunosuppressed patient with IBD as well as provide vaccine-specific recommendations. The evidence suggests that patients with IBD are not receiving recommended vaccinations because of misconceptions on the part of patients as well as a paucity of knowledge by their health care team. Educational programs can be successfully implemented to increase knowledge about appropriate vaccinations and can ultimately increase vaccine uptake among patients with IBD. In the end, gastroenterologists and primary care physicians must work together with their patients with IBD to ensure that recommended vaccinations are administered.

Abstract
Background Occult hepatitis B infection (OBI) is recognized as a risk factor for cirrhosis and hepato-cellular carcinoma. However, OBI brings together a large spectrum of patients who might harbor different characteristics and prognosis. Methods We analyzed the databases of a university hospital in Paris to identify OBI among patients (n = 3966) concomitantly tested for hepatitis B virus (HBV) DNA and serology during a 7-year period. OBI patients were gathered into clinical entities according to their clinical records. Results Forty-seven OBIs were identified (1.2%). All patients had detectable anti-HBc, isolated (n = 26) or associated with anti-HBs (n = 21). The proportion of OBIs was 3.4% for patients with isolated anti-HBc and 4.2% for patients with both anti-HBc and anti-HBs. Four clinical categories of OBI patients were identified: patients with a passed HBV infection with HBs Ag clearance (group A, 23.4%); HBV-exposed patients receiving immunosuppressive therapy (group B, 29.8%); HIV/HBV-coinfected patients with therapy discontinuation (group C, 17%); HBV-exposed patients with severe liver conditions (group D, 29.8%). Significant follow-up was available for 32 patients, showing a more deleterious prognosis in group D patients, associated more with their underlying condition than the OBI status. Conclusions OBI is a heterogeneous condition with various clinical implications.

Abstract
BACKGROUND The role of antiviral prophylaxis before chemotherapy or immunosuppressive therapy to prevent hepatitis B virus (HBV) reactivation in patients with resolved HBV infection [hepatitis B surface antigen (HBsAg) negative, hepatitis B core antibody (anti-HBc) positive] is unclear. This study aimed to evaluate the efficacy of prophylactic antiviral therapy and outcomes of HBsAg-negative, anti-HBc-positive patients who received chemotherapy or immunosuppressive therapy. PATIENTS AND METHODS We retrospectively evaluated the medical records of HBsAg-negative, anti-HBc-positive patients who underwent chemotherapy or immunosuppressive therapy from January 2013 through November 2016 at a single institute in southern Taiwan. RESULTS Among 1000 included HBsAg-negative, anti-HBc-positive patients, the rate of hepatitis B surface antibody (anti-HBs) seropositivity before chemotherapy or immunosuppressive therapy was 76.6%. Twenty-six patients received a prophylactic oral antiviral agent (one telbuvudine, two lamivudine, 22 entecavir, and one tenofovir). Seven (0.7%) patients were diagnosed with HBV reactivation during or after chemotherapy courses. In multivariate Cox regression analysis, an rituximab-based regimen (hazard ratio: 11.74; 95% confidence interval: 1.62-84.94; P=0.02) and baseline anti-HBs-positive status (hazard ratio: 0.17; 95% confidence interval: 0.04-0.8; P=0.03) were significant predictive factors for HBV reactivation. Among anti-HBs-negative recipients of rituximab-based chemotherapy, HBV reactivation was observed in zero of nine patients who received prophylactic antiviral therapy and three (33.3%) of nine patients who did not. CONCLUSION Negative anti-HBs status and rituximab-containing regimens are both important factors for predicting chemotherapy or immunosuppressive therapy-related HBV reactivation in patients with resolved HBV infection. Therefore, antiviral prophylaxis should be considered in this patient population.

Abstract
Background and aims In hepatitis B virus (HBV) carriers receiving chemotherapy, the risk of reactivation is high, particularly if rituximab is given alone or in combination with steroids. The aim of this study was to assess the incidence, prevalence, and clinical course of HBV infection in a cohort of patients with hematological malignancies receiving cytotoxic therapy as well as to propose a strategy for managing HBV reactivation. Methods This is a prospective observational study. All consecutive patients with hematological malignancies receiving intravenous cytotoxic chemotherapy between October 2005 and June 2010 and followed up for at least six months were enrolled in the study. Viral hepatitis markers and liver function indexes were monitored prospectively. Results We enrolled 478 patients, including 263 males (55%) and 465 (97.3%) Italians. Non-Hodgkin's lymphoma was the most frequent diagnosis (66%). At least one HBV marker was positive in 96 patients (20%): 21 (4.4%) patients were HBsAg positive, 17 (3.5%) were anti-HBc positive, and 58 (12.1%) were anti-HBc/anti-HBs positive. All but one HBsAg-positive patient received therapy with nucleoside/nucleotide analogs prior to chemotherapy. All but three reached complete virological suppression at six months from the start of treatment. Of the 17 HBsAg-negative/anti-HBc-positive patients, three (18%) had reactivation with seroreversion. All three obtained viral suppression with adefovir. Regarding the 58 anti-HBc/anti-HBs-positive patients, two (3.4%) experienced seroreversion and were treated successfully with nucleoside analogs; both were taking rituximab. No severe ALT flares were observed during or after antiviral therapy. Conclusion Our data suggest that pre-treatment screening of patients at risk of viral reactivation yields benefit and therefore should be practiced by clinicians treating patients with malignancies.

Abstract
Objectives Currently, no consensus exists regarding the optimal oral prophylactic regimens for hepatitis B surface antigen seropositive patients undergoing chemotherapy. We aimed to compare the efficacy of oral nucleos(t)ide analogues (NAs), including lamivudine, entecavir, adefovir, telbivudine and tenofovir, for the prevention of chemotherapy-induced hepatitis B virus (HBV) reactivation and its related morbidity and mortality in patients with chronic HBV (CHB) infection. Results Fifty-two eligible articles consisting of 3892 participants were included. For HBV reactivation, prophylactic treatment with NAs were all significantly superior to no prophylaxis, with odds ratio (OR) from 0.00 (95% confidence interval [CI] 0.00~0.04) for the most effective intervention (tenofovir) to 0.10 (95% CI 0.06~0.14) for the least effective intervention (lamivudine). For secondary outcomes, prophylaxis with NAs also significantly outperformed observation. The results suggested that entecavir reduced the risk of HBV related hepatitis (predicted probability, 83%), HBV related death (68%) and all causes of hepatitis (97%) most efficaciously. It ranked second in decreasing all causes of death (34%). Materials and Methods PubMed, Embase and Cochrane Library database were searched for controlled trials up to March 31, 2015. Primary outcome was the incidence of HBV reactivation. Secondary outcomes included the incidence of HBV-related hepatitis and death, all causes of hepatitis and death. Network meta-analysis combined direct and indirect evidence to estimate ORs for the clinical outcomes. A mean ranking and the probability of optimal therapeutic regime was obtained for each treatment based on clinical outcomes. Conclusions Available evidence suggests that prophylatic therapy with tenofovir and entecavir may be the most potent interventions in prevention of HBV reactivation and HBV-related morbidity and mortality for CHB infection patients undergoing chemotherapy.

Abstract
Hepatocellular carcinoma (HCC) is a leading cause of death globally and is frequently seen following Hepatitis B virus (HBV) or Hepatitis C virus infection. Areas with high HBV infection rates, such as Asia and sub-Saharan Africa, are therefore also high-risk areas for HCC. Areas covered: This review identifies and discusses the current evidence from robust clinical trials which have investigated the benefits of Nucleos(t)ide analogue (NA) antiviral therapy in HBV-related HCC patients, including HCC patients that underwent liver transplantation and HCC patients with or without curative treatment. In addition, we assess how this evidence has influenced current clinical practice, with a particular focus on those areas of high HBV infection rates. Expert commentary: A number of studies have assessed whether NA antiviral treatment can improve the prognosis of HBV-related HCC patients. In this review we evaluate the current evidence, including that from trials in Asia, for antiviral NA treatments in HBV-related HCC patients. We also focus on those NAs with a high genetic barrier to resistance (i.e. ETV or TDF), on different therapeutic approaches, and on the future evidence that is required in this field.

Abstract
Lung cancer represents a major public health issue worldwide. Unfortunately, more than half of them are diagnosed at an advanced stage. Moreover, even if diagnosed early, diagnosis procedures and treatment can be difficult due to the frequent comorbidities observed in these patients. Some of these comorbidities have a common major risk factor, i.e. smoking, whereas others are unrelated to smoking but frequently observed in the general population. These comorbidities must be carefully assessed before any diagnostic and/or therapeutic decisions are made regarding the lung cancer. For example, in a patient with severe emphysema or with diffuse lung fibrosis, transthoracic needle biopsy can be contraindicated, meaning that in some instances a precise diagnosis cannot be obtained; in a patient with chronic obstructive pulmonary disease, surgery may be impossible or should be preceded by intensive rehabilitation; patients with interstitial lung disease are at risk of radiation pneumonitis and should not receive drugs which can worsen the respiratory insufficiency. Patients who belong to what are called "special populations", e.g. elderly or HIV infected, should be treated specifically, especially regarding systemic treatment. Last but not least, psychosocial factors are of great importance and can vary from one country to another according to health insurance coverage.

Abstract
Hepatitis B virus (HBV) reactivation with imatinib, a tyrosine kinase inhibitor, has been reported in chronic myeloid leukemia. Nilotinib is a more potent second generation tyrosine kinase inhibitor and it inhibits the Src-family kinase LCK and hamper proliferation and function of CD8 (+) T lymphocytes. CD8 (+) T lymphocytes are the main cellular subset responsible for viral clearance in patients with HBV infection. We report a case of HBV reactivation under treatment with nilotinib. Fatal HBV reactivation is not usually related to death in chronic myeloid leukemia patients who have an expectation of longevity with well-tolerated oral drugs. Thus, screening for latent chronic HBV infections including assessment of hepatitis B surface antigen (HBsAg), antibody to hepatitis B core antigen (anti-HBc antibody) and antibody to hepatitis B surface antigen (anti-HBs), especially at countries with intermediate and high prevalence of HBsAg is warranted. Treatment with nucleoside analogs and close monitoring may be life-saving in this context.

Abstract
PURPOSE To elucidate the rate and risk factors of HBV reactivation in patients with chronic HBV infection with low replicative state and resolved HBV infection undergoing allogenic/autologous hematopoietic stem-cell transplantation (HSCT) in Korea. METHODS The medical charts of 506 patients who underwent allogenic/autologous HSCT from January 2008 to December 2013 were analyzed retrospectively. We examined the reactivation rate and variables related to the risk of HBV reactivation, with a median follow-up period of 41.8 (1-245) months. Univariate analysis was used to identify any factors associated with HBV reactivation. Factors that were significant in the univariate analysis were entered into a stepwise multivariate analysis to find the most significant risk factors associated with HBV reactivation. RESULTS The reactivation rate of HBV in patients who underwent HSCT was 4.2 % (21/506). In subgroup analysis, the HBV reactivation rate (14.3 %) was the highest among HBsAg(+) patients (5/35). The reactivation rate of HBV in patients with resolved HBV infection [HBsAg(-)/HBcAb(+) with or without anti-HBs antibody] was 5.9 % (10/171). In univariate analysis for risk factors of HBV reactivation in patients who underwent HSCT, initial detectable HBV DNA (p = 0.004), age (≥60 years) (p = 0.012), recipient hepatitis B surface antigen-positive (HbsAg)(+) before HSCT (p = 0.004), recipient hepatitis B surface antibody-negative (HBsAb)(-) before HSCT (p = 0.005), recipient hepatitis B core antibody-positive (HbcAb)(+) before HSCT (p = 0.013), and donor HBsAg(+) (p < 0.001) were associated with reactivation of HBV. In multivariate analysis, significant risk factors of HBV reactivation in patients who underwent HSCT were old age (≥60 years) (p = 0.032) and donor HBsAg(+) (p = 0.026). CONCLUSION Old age (≥60 years) and donor HBsAg(+) were risk factors for HBV reactivation in HSCT patients. Preemptive antiviral treatment should be considered in these patients.

Abstract
Liver cirrhosis, the end-stage of every chronic liver disease, is not only the major risk factor for the development of hepatocellular carcinoma but also a limiting factor for anticancer therapy of liver and non-hepatic malignancies. Liver cirrhosis may limit surgical and interventional approaches to cancer treatment, influence pharmacokinetics of anticancer drugs, increase side effects of chemotherapy, render patients susceptible for hepatotoxicity, and ultimately result in a competitive risk for morbidity and mortality. In this review, we provide a concise overview about the impact of liver cirrhosis on the management and prognosis of patients with primary liver cancer or non-hepatic malignancies.

Abstract
BACKGROUND This proof-of-concept study compared lamivudine (LAM) with a newer antiviral agent, adefovir dipivoxil (ADF), in preventing hepatitis B virus (HBV) reactivation in chronic HBV patients undergoing chemotherapy. METHODS Hepatitis B surface antigen (HBsAg) positive patients intended to undergo chemotherapy were randomized to receive either LAM 100 mg daily or ADF 10 mg daily. Anti-viral therapy was started 1 week prior to chemotherapy and until 6 months after completing chemotherapy. The primary outcome was HBV reactivation rate. All patients with viral breakthrough were screened for resistance mutations by direct sequencing. RESULTS Seventy treatment-naïve patients were consecutively randomized 1:1 to LAM or ADF. The median baseline HBV DNA levels were similar (LAM 3.36 vs. ADF 3.17 log10 copies/mL, p = 0.860). The median duration was 8.3 months on LAM and 10.6 months on ADF (p = 0.220). HBV reactivation was observed in 13/35 (37.1%) on LAM compared with 10/35 (28.6%) on ADF (p = 0.611). The median time to HBV reactivation was 4.6 and 8.1 months, on LAM and ADF respectively. Among these 13 patients, 8/13 (61.5%) on LAM had developed drug resistance mutations but none on ADF had developed drug resistance mutations to ADF (p = 0.003). Both drugs were well tolerated and no severe drug-related toxicities were reported. CONCLUSION In this randomized clinical study, adefovir and lamivudine demonstrated similar efficacy in preventing hepatitis B reactivation in HBsAg-positive patients undergoing chemotherapy. In patients whose hepatitis B reactivated, adefovir was associated with a lower resistance profile.

Abstract
Reactivation of remote hepatitis B infection (RHBI) is an important cause of morbidity in hematopoietic cell transplant (HCT) patients. We analyzed the prevalence of RHBI in 205 patients who underwent HCT in our centre, serological events related to hepatitis B virus (HBV) reactivation and role of lamivudine prophylaxis in HCT patients with RHBI. The prevalence of RHBI was 14% (28/205 patients). Of these 28 patients, 15 received lamivudine prophylaxis (14 anti-HBcIgG positive and 1 only anti-HBs positive) while 13 did not receive lamivudine prophylaxis (12 anti-HBs positive and 1 anti-HBcIgG positive). None in prophylaxis group developed HBV reactivation while 12 of 13 in no-prophylaxis group reactivated (P < 0.001). The rate of HBV reactivation was 10% (21/205 patients), which included 9 patients with no evidence of RHBI pre-transplant. We conclude that lamivudine prophylaxis protects against HBV reactivation in HCT patients with evidence of RHBI. Lamivudine prophylaxis should be used not only in patients with anti-HBcIgG positivity but also in those with isolated anti-HBs positivity pre-transplant given the high rate of HBV reactivation in these patients. HBV serology cannot identify all cases with RHBI and therefore does not preclude HBV reactivation post-transplant. Copyright © 2015 John Wiley & Sons, Ltd.

Abstract
INTRODUCTION Hepatitis B virus (HBV) flare is a serious problem following hematopoietic stem cell transplantation (HSCT), and the mortality rate is high if severe hepatitis occurs. CASE DESCRIPTION Although Entecavir (ETV) is a standard antiviral drug for HBV infection, the efficacy and safety of ETV therapy in HSCT are still unclear. DISCUSSION AND EVALUATION To examine the efficacy and tolerability of ETV treatment in HSCT, we retrospectively identified 5 patients who received ETV for treatment of HBsAg carrier among patients undergoing HSCT in our institute. We reviewed their clinical information such as clinical course of serum HBV DNA levels, administration period and dose of ETV, and adverse events. There were no episodes of HBV flare or reactivation after HSCT in all patients during the observation period, as a 10-fold rise in HBV DNA levels or positive conversion of HBsAg were not observed. CONCLUSION ETV monotherapy is effective and safe for HBsAg carrier patients following HSCT.

Abstract
Hepatitis B virus (HBV) infection continues to be a major public health problem worldwide. Although treatment indications are well established in clinical practice guidelines, there are some risk groups, such as pregnant women and immunosuppressed patients, who require different and specific management of HBV infection. In pregnant women, treatment indication should be individualized and the risk of HBV transmission to the newborn evaluated because cases of vertical transmission continue to be reported, despite active and passive immunoprophylaxis. In patients receiving immunosuppressive therapy, HBV reactivation is associated with high morbidity and mortality, even in patients with past HBV infection, highlighting the importance of screening and the need to evaluate prophylactic therapy in some cases.

Hepatitis B virus reactivation in hepatitis B surface antigen seropositive patients with metastatic non-small cell lung cancer receiving cytotoxic chemotherapy: the efficacy of preemptive lamivudine and identification of risk factors.

Abstract
Little is known about the likelihood and degree of hepatitis B virus (HBV) reactivation in hepatitis B surface antigen (HBsAg) seropositive patients with disseminated non-small cell lung cancer (NSCLC) receiving chemotherapy. Between January 2003 and December 2013, all HBsAg seropositive patients with metastatic NSCLC receiving cytotoxic chemotherapy were retrospectively evaluated. The morbidity and mortality of HBV reactivation, risk factors associated with reactivation, as well as the efficacy of preemptive lamivudine were investigated. Of 258 patients who were eligible for the present study, 176 were treated without antiviral prophylaxis and 82 received preemptive lamivudine. Patients without lamivudine prophylaxis had a significantly higher prevalence of HBV reactivation (19.3 vs 6.1 %, p = 0.006) and severe hepatitis attributable to reactivation (11.8 vs 3.7 %, p = 0.034) than those with preemptive lamivudine. However, no significant difference in mortality due to reactivation was noted between patients with or without prophylactic lamivudine (0 vs 2.3 %, p = 0.310). Furthermore, patients who developed HBV reactivation were indentified to have a higher rate of HBeAg seropositivity (74.4 vs 43.4 %, p < 0.001), serum HBV-DNA level of 10(4) copies/ml or greater (76.9 vs 47.9 %, p = 0.001), coexisting liver metastasis (50.0 vs 40.6 %, p = 0.033) and treatment with more than 4 cycles of chemotherapy (56.4 vs 39.3 %, p = 0.046) than those who did not experienced reactivation. The current study has demonstrated that preemptive lamivudine significantly reduced the prevalence of HBV reactivation in HBsAg seropositive patients with metastatic NSCLC receiving systemic chemotherapy.

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

Abstract
Lack of an appropriate small animal model remains a major hurdle for studying the immunotolerance and immunopathogenesis induced by hepatitis B virus (HBV) infection. In this study, we report a mouse model with sustained HBV viremia after infection with a recombinant adeno-associated virus (AAV) carrying a replicable HBV genome (AAV/HBV). Similar to the clinical HBV carriers, the mice infected with AAV/HBV were sero-negative for antibodies against HBV surface antigen (HBsAg). Immunization with the conventional HBV vaccine in the presence of aluminum adjuvant failed to elicit an immune response against HBV in these mice. To identify a vaccine that can potentially circumvent this tolerance, the TLR9 agonist CpG was added to HBsAg as an adjuvant. Vaccination of mice with HBsAg/CpG induced not only clearance of viremia, but also strong antibody production and T-cell responses. Furthermore, both the DNA replication and protein expression of HBV were significantly reduced in the livers of AAV/HBV-infected mice. Accordingly, AAV/HBV-infected mice may be used as a robust model for investigating the underlying mechanism(s) of HBV immunotolerance and for developing novel immunotherapies to eradicate HBV infections.

Abstract
B-cell depletion may impair vaccine responses and increase infection risk in patients with immune thrombocytopenia (ITP). We investigated the effects of rituximab on antibody and cellular responses to Streptococcus pneumoniae polysaccharide and Haemophilus influenzae type b (Hib) vaccines in ITP patients. Of 60 patients in the main trial, 24 patients received both vaccines 6 months after rituximab (n = 17) or placebo (n = 7). Among 20 evaluable patients, 3 of 14 (21%) in the rituximab group and 4 of 6 (67%) in the placebo group achieved a fourfold increase in anti-pneumococcal antibodies (P = .12). For anti-Hib antibodies, 4 of 14 (29%) and 5 of 6 (83%), respectively, achieved a fourfold increase (P < .05). Fewer patients in the rituximab group demonstrated Hib killing (2 of 14 [14%], 5 of 6 [83%], P < .05). Three of 14 rituximab-treated patients failed to respond to vaccines by any criteria. After vaccinations, preplasma cell blasts and interferon-γ-secreting T cells were reduced in rituximab-treated patients. Antibody responses were impaired for at least 6 months after rituximab. Cellular immunity was reduced in parallel with depleted B-cell pools. These findings have implications for the timing of vaccinations and the mechanism of infection after rituximab in ITP patients.

Abstract
OBJECTIVES The aim of this study was to determine the prevalence of HBV infection among pregnant women in districts of Eastern Slovakia with a diverse prevalence of Roma population. METHODS Overall 59,279 serum samples from 9 regional departments of clinical microbiology from Eastern Slovakia were collected in the period from January 2008 till December 2009 and analysed. RESULTS The number of HBsAg positive samples overall and during pregnancy was 1.74% and 2.12%, respectively. Comparing districts with higher (> 5%) and lower (< 5%) Roma population, there was no significant difference in the prevalence of HBsAg positive samples overall (1.95% vs.1.62%). However, in the subgroup of pregnant women the prevalence of HBsAg positive samples (2.72% vs. 0.95%) differs significantly (p < 0.01). CONCLUSIONS The prevalence of HBV infection among pregnant women in Eastern Slovakia did not rapidly exceed the estimated nationwide prevalence. However, in districts with higher Roma population the expected higher prevalence of HBV infection was confirmed. This indicates the need to pay special attention to the prevention of hepatitis B in these districts.

Abstract
HBV infection remains a major global health problem and continues to be a common cause of liver-related morbidity and mortality in both immunocompetent and immunosuppressed individuals. Reactivation of HBV is a serious complication of chemotherapy/immunosuppressive therapy in patients with HBV infection. In this article, we aim to describe the diagnosis, prevention and management of HBV infection in allogeneic hematopoietic stem cell transplant candidates, from the pre- to post-transplant period. The data currently available suggest that all individuals with hemato-/onco-logical malignancies who undergo chemotherapy/immunosuppressive therapy should be screened for hepatotropic viruses such as HBV and HCV. HBV surface antigen-positive individuals who receive chemotherapy/immunosuppressive therapy are at considerable risk of HBV reactivation. Antiviral prophylaxis prevents HBV reactivation, decreases reactivation-related morbidity and mortality, and prevents interruptions in chemotherapy/immunosuppressive therapy in such individuals. The optimal duration of antiviral prophylaxis remains to be elucidated. The vaccination of HBV-naive recipients and their donors against HBV infection prior to transplantation plays an important role in preventing acquired HBV infection. The presence of hepatitis B surface antigen positivity is not an absolute contraindication for allogeneic hematopoietic stem cell transplantation.

Abstract
The aim of this study was to analyze the clinical features of hepatitis B surface antigen (HBsAg)-positive and negative diffuse large B-cell lymphomas (DLBCLs) and to compare the outcomes and serum hepatitis B virus (HBV)-DNA loads of patients treated with cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP) regimens with rituximab (RCHOP) or without. A total of 451 DLBCL patients, of which 90 were HBsAg-positive and 361 were HBsAg-negative, were retrospectively reviewed. We compared onset age, gender, Ann Arbor stage, international prognostic index (IPI), lactate dehydrogenase (LDH) and β2-microglobulin (β2-M) levels, as well as overall survival (OS) rates and HBV-DNA loads under CHOP or RCHOP regimens. The OS rate of the HBsAg-positive DLBCL patients was significantly lower than that of HBsAg-negative DLBCL patients and the HBsAg-positive DLBCL patients had an earlier median onset age. HBsAg-positive DLBCL patients had poorer OS rates compared with HBsAg-negative patients (62.2% HBsAg-positive vs. 76.2% HBsAg-negative, P=0.018). HBsAg-positive DLBCL patients with HBV-DNA loads >103 cps/ml during chemotherapy had significantly lower OS rates than those with lower HBV-DNA loads (48.4% HBV-DNA elevated vs. 71.2% HBV-DNA normal, P=0.037). HBsAg-positive DLBCL patients treated with RCHOP had a significantly higher OS rate (79.6%) compared with the 41 CHOP-treated patients (43.9%; P<0.001). HBsAg-positive DLBCL patients with an earlier median onset age and elevated HBV-DNA during chemotherapy had poorer prognoses. HBsAg and HBV-DNA during chemotherapy may be used as prognostic indicators for patients with DLBCL. Rituximab improves the outcome of HBsAg-positive DLBCL patients when administered in combination with anti-viral lamivudine.

Abstract
Hepatitis B virus (HBV) reactivation is a well-recognized complication in patients with chronic HBV infection receiving cytotoxic or immunosuppressive chemotherapy. Imatinib mesylate and nilotinib are selective Bcr/Abl tyrosine kinase inhibitors, which are now widely used in the treatment of patients with chronic myeloid leukemia. Although HBV reactivation induced by imatinib mesylate has been reported, nilotinib-related HBV reactivation has not been reported in the English literature. We report here 2 cases of HBV reactivation in chronic myeloid leukemia patients receiving imatinib mesylate and a novel case of nilotinib related HBV reactivation.

Abstract
Reactivation of hepatitis B virus (HBV) or hepatitis C virus (HCV) infection following anticancer chemotherapy and immunosuppressive therapy is a well-known complication. HBV reactivation has been reported to be associated with anti-CD20 monoclonal antibody rituximab-containing chemotherapy and tumor necrosis factor-α inhibitor-containing immunosuppressive therapy in HBV resolved patients (hepatitis B surface antigen negative and antibodies against hepatitis B core antigen positive and/or antibodies against surface antigen positive). On the other hand, HCV reactivation has been reported to be associated with liver damage or hepatic dysfunction, but fulminant hepatitis due to HCV reactivation is a rare complication. In this review, we describe the pathophysiology of the reactivation of HBV and HCV infection, as well as the clinical evidence and management of HCV reactivation.

Abstract
A woman in her early 50s was admitted to the intensive care unit with nausea, altered mental status and hepatic failure. She had a history of asymptomatic chronic hepatitis B and recently received chemotherapy for breast cancer. A diagnosis of hepatitis B reactivation (HBR) was made, but unfortunately she died of liver failure. Controversies around testing for hepatitis B prior to giving immunosuppressive treatments and the use of prophylactic antiviral therapy to prevent HBR are discussed.

Abstract
Hepatitis B is a major cause of liver disease worldwide. The highest rates of chronic infection occur in subjects who are infected early in life and these patients are also at the greatest risk of developing complications such as hepatocellular carcinoma and cirrhosis from the disease. There has been a concerted worldwide effort to immunise newborns that are at the highest risk of acquiring infection. In 1992, when WHO recommended global vaccination against hepatitis B, only 31 countries elected to participate in the programme. By 2009, 177 countries were part of WHO national infant immunisation programme. Consequently, maternal screening and infant immunoprophylaxis have significantly reduced vertical transmission of hepatitis B. In this paper, we will review the management of hepatitis B in the pregnant population and identify some of the challenges that are encountered in this specialised population.

Abstract
Reactivation of hepatitis B virus (HBV) infection is a known complication during and after anti-cancer therapy. This condition can affect two patient populations: it is most commonly seen in patients who are seropositive for hepatitis B surface antigen (HBsAg), but it is also being increasingly reported among patients who are HBsAg-negative but who have prior infection, as evident by seropositive status for antibody to hepatitis B core antigen (anti-HBc), irrespective of their anti-HBs (antibody to HBsAg) status. The clinical course can vary from asymptomatic hepatitis to fulminant hepatic failure that can be potentially fatal. With the increasing use of biological agents in addition to potent cytotoxic chemotherapy in the armamentarium of anti-cancer treatments, reactivation of hepatitis B has become a common clinical situation that is faced by both oncologists and hepatologists especially in HBV endemic areas. In this review, we discuss the clinical course of reactivation in the two HBV-infected sub-populations, and the role of anti-virals in the prevention and management of HBV reactivation in association with cytotoxic chemotherapy and biological therapies.

Abstract
PURPOSE Reactivation of hepatitis B virus (HBV) is a common complication in patients with HBV infection who receive cytotoxic chemotherapy. In rituximab-containing chemotherapy for B-cell lymphoma, severe hepatitis due to HBV reactivation occurred. The aim of this study is to estimate the effect of prophylactic lamivudine on the risk of HBV reactivation in patients with HBV infection who receive rituximab-containing chemotherapy. METHODS In this study, HBV markers and liver function tests were monitored in 268 consecutive patients with B-cell lymphoma, who received rituximab-containing chemotherapy between January 2008 and November 2011. Sixty-nine patients (25.7 %) with either chronic HBV infection or past HBV infection received prophylaxis with lamivudine 100 mg daily by oral intake. RESULTS In the HBsAg-positive group, six (6/38) patients developed hepatitis, only one of which was attributed to HBV reactivation. In the HBsAg-negative and HBcAb-positive group, two (2/31) patients developed hepatitis, none of which was attributed to HBV reactivation. CONCLUSIONS These results support that prophylactic lamivudine can prevent HBV reactivation for B-cell lymphoma with HBV infection who was receiving rituximab-containing chemotherapy.

Abstract
BACKGROUND Little is known about the clinical features of hepatitis B virus (HBV) infection in patients with inflammatory bowel disease (IBD). We therefore evaluated the influence of immunosuppressive treatment for IBD on the course of HBV infection and the effect of HBV infection on the therapeutic strategy and clinical course of IBD patients. METHODS We retrospectively evaluated the incidence of and risk factors for liver dysfunction in hepatitis B surface antigen (HBsAg)-positive IBD patients. Also, the clinical course of IBD patients with HBV infection was compared with matched IBD controls without HBV infection. RESULTS Of 4153 patients diagnosed with IBD between July 1989 and May 2011, 134 were HBsAg-positive, including 54 with Crohn's disease (CD) and 80 with ulcerative colitis (UC). Liver dysfunction was observed in 23 of the 134 (17.2%) HBsAg-positive patients. Prolonged immunosuppression (>3 months) was an independent predictor of liver dysfunction (odds ratio [OR] 3.06; 95% confidence interval [CI] 1.02-9.16). The rate of use of immunosuppressants, including corticosteroids (P = 0.005), azathioprine/6-mercaptopurine (P < 0.001), and infliximab (P = 0.026), was significantly lower in HBsAg-positive than HBsAg-negative IBD patients. Clinical outcomes, including admission rate, mean number of admissions, total proctocolectomy in UC patients, and mortality were worse in HBsAg-positive than HBsAg-negative IBD patients during the follow-up period. CONCLUSIONS Liver dysfunction in HBsAg-positive IBD patients was more frequent in those with prolonged immunosuppression. IBD patients with chronic HBV infection used immunosuppressants less frequently and had a worse prognosis than those without it.

Abstract
Hepatitis B virus (HBV) reactivation is well documented in previously resolved or inactive HBV carriers who receive cancer chemotherapy. The consequences of HBV reactivation range from self-limited conditions to fulminant hepatic failure and death. HBV reactivation also leads to premature termination of chemotherapy or delay in treatment schedules. This review summarizes current knowledge of management of HBV reactivation in patients receiving cancer chemotherapy. HBV surface antigen (HBsAg) testing should be performed in patients who require cancer chemotherapy. Four meta-analyses support lamivudine prophylaxis for HBV reactivation during chemotherapy in HBsAg-positive patients. Randomized controlled trials to compare different HBV antiviral agents are needed to define optimal regimens for the prevention and treatment of HBV reactivation in patients receiving cancer chemotherapy.

Abstract
CONTEXT Occult hepatitis B (OHB), or persistent HBV DNA in patients who are hepatitis B surface antigen (HBsAg) negative, is a recently recognized entity. In an attempt to summarize the issues, this review presents an overview of the current proposed hypothesis on the clinical relevance and also updates the knowledge on the classification of OHB in different clinical settings. EVIDENCE ACQUISITION OHB COULD BE FOUND IN DIFFERENT POPULATION AND CLINICAL BACKGROUNDS INCLUDING: viral co-infections (with either human immunodeficiency or hepatitis C viruses), HBV chronic carriers, dialysis patients, transplantation settings and certain clinical situations (named in here: special clinical settings) with no apparent distinguishable clinical parameters. RESULTS The exact magnitude, pathogenesis, and clinical relevance of OHB are unclear. Even the possible role exerted by this cryptic infection on liver disease outcome, and hepatocellular carcinoma development remains unknown. CONCLUSIONS Monitoring of Individuals with positive anti-HBc, mass immunization programs and improvement in diagnostic tools seem to be important to control the probability of transmission of HBV through cryptic HBV infection.

Abstract
With the increasing use of potent immunosuppressive therapy, reactivation of hepatitis B virus (HBV) in endemic regions is becoming a clinical problem requiring special attention. A recent annual nationwide survey clarified that HBV reactivation related to immunosuppressive therapy has been increasing in patients with malignant lymphoma, other hematological malignancies, oncological or rheumatological disease. In the survey, rituximab plus steroid-containing chemotherapy was identified as a risk factor for HBV reactivation in hepatitis B surface antigen (HBsAg) negative patients with malignant lymphoma. In this setting, HBV reactivation resulted in fatal fulminant hepatitis regardless of the treatment of nucleoside analog. The Intractable Hepatobiliary Disease Study Group and the Study Group for the Standardization of Treatment of Viral Hepatitis Including Cirrhosis jointly developed guidelines for preventing HBV reactivation. The essential features of the guideline are as follows. All patients should be screened for HBsAg by a sensitive method before the start of immunosuppressive therapy. Second, hepatitis B core antigen (HBcAb) and hepatitis B surface antibody (HBsAb) testing should be performed in HBsAg negative patients, especially those receiving intensive immunosuppressive therapy. Prophylaxis with nucleoside analogs is essential for preventing HBV reactivation in HBsAg positive patients. In contrast, HBsAg negative with HBcAb and/or HBsAb positive patients should be monitored monthly for an increase in serum HBV DNA during and 12 months after completion of chemotherapy. Nucleoside analogs should be administrated immediately when HBV DNA becomes positive during this period. This strategy facilitates commencement of nucleoside analogs at an early stage of HBV reactivation and results in prevention of severe hepatitis.

Abstract
Background/Aims Enhanced replication of hepatitis C virus (HCV) is well described in the setting of moderate to severe immunosuppression. The aims of this retrospective study were to determine the incidence of enhanced HCV replication in hepatocellular carcinoma (HCC) patients undergoing transarterial chemolipiodolization (TACL) and to identify the factors associated with enhanced replication of HCV. The clinical pattern of enhanced HCV replication was compared with hepatitis B virus (HBV) reactivation during TACL. Methods This study enrolled 49 anti-HCV-seropositive patients who were diagnosed with HCC between January 2005 and December 2010 and who underwent TACL using epirubicin and/or cisplatin with consecutive HCV RNA copies checked. For comparison, 46 hepatitis B surface antigen1-positive patients with HCC who were treated with TACL were also enrolled. The frequency, associated factors, and clinical outcomes of enhanced HCV replication were analyzed and compared with those of HBV reactivation during TACL. Results Enhanced replication of HCV occurred in 13 (26.5%) of the 49 anti-HCV-seropositive patients during TACL. Of these 13 patients, 4 developed hepatitis, but none of the subjects developed decompensation due to the hepatitis. No significant clinical factors for enhanced HCV replication during TACL were found. Compared with HBV reactivation, the frequency of hepatitis attributed to enhanced HCV replication was significantly lower than that for HBV reactivation (8.2% vs. 23.9%, P=0.036). Conclusions TACL can enhance HCV replication; however, the likelihood of hepatitis and decompensation stemming from enhanced HCV replication was lower than that for HBV reactivation in patients undergoing TACL.

Abstract
Infections with hepatitis B virus (HBV) or hepatitis C virus (HCV) are associated with significant morbidity and mortality among patients with cancer, especially in patients with hematologic malignancies and those who undergo hematopoietic stem-cell transplantation. Reported rates of HBV reactivation in HBV carriers who undergo chemotherapy range from 14-72%. In these patients, mortality rates range from 5-52%. HCV reactivation seems to be less common than HBV reactivation and is usually associated with a good outcome and low mortality. However, once severe hepatitis develops, as a result of viral reactivation, mortality rates seem to be similar among patients infected with HBV or HCV. Liver damage owing to viral reactivation frequently leads to modifications or interruptions of chemotherapy, which can negatively affect patients' clinical outcome. Risk factors for the development of severe HBV or HCV reactivation need to be better defined to permit identification of patients who may benefit from preventive measures, early diagnosis, and therapy. In this article, we review the epidemiology, pathogenesis, risk factors, and clinical and laboratory manifestations associated with reactivation of HBV and HCV during immunosuppressive therapy. We also discuss strategies for the prevention and treatment of viral reactivation, including the management of reactivation with new antiviral agents.

Abstract
Hepatitis B is one of the leading causes of chronic hepatitis in developing countries, with 5% to 15% of the population carrying virus. The high prevalence is due to failure to adopt appropriate measure to confine the spread of infection. Most hepatitis B patients present with advanced diseases. Although perinatal transmission is believed to be an important mode, most infections in the developing world occur in childhood and early adulthood. Factors in developing countries associated with the progression of chronic hepatitis B (CHB) include co-infections with human immunodeficiency virus, delta hepatitis virus, hepatitis C virus, alcohol intake and aflatoxin. Treatment protocols extrapolated from developed countries may need modifications according to the resources available. There is some controversy as to when to start treatment, with what medication and for how long? There is now enough evidence to support that hepatitis B patients should be considered for treatment if they show persistently elevated abnormal aminotransferase levels in the last 6 mo, checked on at least three separate occasions, and a serum hepatitis B virus DNA level of > 2000 IU/mL. Therapeutic agents that were approved by Pure Food and Drug Administration are now available in many developing countries. These include standard interferon (INF)-α, pegylated INF-α, lamivudine, adefovir, entecavir and telbivudine. Drug resistance has emerged as a major challenge in the management of patients with CHB. The role of the universal vaccination program for effective control of hepatitis B cannot be emphasized enough.

Abstract
BACKGROUND The understanding of the distribution of hepatitis B virus genotypes and the occult hepatitis B virus infection in hepatocellular carcinoma may shed light into the prevention and treatment of hepatocellular carcinoma. The purpose of the study is to investigate hepatitis B virus genotypes distribution, the high-risk genotypes and the occult infection in north-western China's hepatocellular carcinoma patients. METHODS Hepatitis B virus genotypes A-D of hepatocellular carcinoma tumor tissues and serum samples in 268 north-western China hepatocellular carcinoma patients were detected by fluorescence polarization assay. The hepatitis B virus genotypes in serum and matched primary tumor tissue samples were compared. Hepatitis B surface antigen and α-fetoprotein in serum were detected. Occult hepatitis B virus infections were analyzed. The relationship between hepatitis B virus genotypes and clinicopathologic characteristics were analyzed statistically using SPSS v.10.0. RESULTS Intrahepatic hepatitis B virus DNA was detected in 83.6% of 268 patients, whereas serum hepatitis B virus DNA was detected in 78.7%. The hepatitis B virus genotypes in serum were consistent with the results in matched tumor tissue. Intrahepatic hepatitis B virus genotype B and C were detected respectively in 11.6% and 54.5% of the patients. Mixed intrahepatic hepatitis B virus genotypes were detected in 13.4% of 268 patients. There was not mixed hepatitis B virus infection in Edmondonson grade I. The patients with mixed HBV genotypes exhibited statistically significant different Edmondson grade than the patients with single type HBV infection (p < 0.05). Hepatitis B surface antigens were positive in 77.2% of 268 patients. Hepatitis B virus genotype C was detected in 64.7% of occult infected patients. There was no significant differences of patients' ages and α-fetoprotein level in different groups of intrahepatic hepatitis B virus genotypes (p > 0.05). CONCLUSIONS Hepatitis B virus genotype C was associated closely with the development of hepatocellular carcinoma and the occult hepatitis B virus infection in patients in north-western China. There was a relatively high prevalence of mixed hepatitis B virus infection in Edmondonson grade III-IV.

Abstract
Epidemiological studies have shown a relationship between hepatitis B virus (HBV) infection and development of proteinuria in some patients (most commonly children), with a predominance for male gender and histological findings of membranous nephropathy on renal biopsy. The presence of immune complexes in the kidney suggests an immune complex basis for the disease, but a direct relation between HBV and membranous nephropathy (or other types of glomerular diseases) remains to be proven. Clearance of HBV antigens, either spontaneous or following antiviral treatments results in improvement in proteinuria. Thus, prompt recognition and specific antiviral treatment are critical in managing patients with HBV and renal involvement. The present review focuses on treatment of HBV with special emphasis given to antiviral therapies, its complications, and dosing in patients with HBV-associated kidney disease.

Abstract
BACKGROUND Occult HBV infection accelerates the progression of liver fibrosis, cirrhosis, and finally leading to hepatocellular carcinoma (HCC). This study analyzed the occult HBV-genotypes in HCC patients. METHODS To achieve our objective, matched serum and tissue samples were collected from 40 HCC patients. Three sets of primers were used for the HBV-DNA detection by nested-PCR, which cover the HBV-genome; Core, Surface and X genes. Genotyping system based on PCR using type-specific primers was applied on HBV-DNA positive samples. RESULTS Intrahepatic occult HBV-DNA was detected in 62.5%, whereas; Serum occult HBV-DNA were detected in only 22.5% of HCC patients. In patients' positive for both anti-HBs and anti-HBc, 10% had occult HBV in serum. In serologically negative HCV patients, 63% had intrahepatic HBV-DNA, and 21% had HBV-DNA in serum samples. HBV-genotype D (32%) and B (24%) attributed predominantly to intrahepatic HBV infections in HCC patients, whereas HBV-genotype A (4%) and C (8%) infections were the least observed. CONCLUSION This is the first study to show the genotypes of occult HBV infection in HCC Patients. We suggest that B or D may influence the outcome of HBV infection which may lead to the development of HCC.

Abstract
HBV reactivation in patients with haematological malignancies undergoing chemoimmunotherapy is a serious and frequent complication. This is linked to either the high frequency of inactive HbsAg carriers and occult B infection among oncohaematological patients or the profound immunosuppression caused by high dose chemotherapy, monoclonal antibody therapy or auto- and allo-haematopoietic stem cell (HSC) transplantations. Identifying the patients at risk is mandatory in this clinical setting and prophylaxis with antiviral drugs or close monitoring may reduce and/or eliminate the HBV reactivation risk and the serious consequences. In general, preemptive anti-HBV therapy is more effective than treatment at reactivation. Prompt lamivudine prophylaxis should be given to HBsAg positive patients (inactive carriers) undergoing chemotherapy-immunochemotherapy and continued after cessation of immunosuppression even though long-term lamivudine therapy involves a risk of developing drug resistance. Use of newer anti-HBV agents may be considered. HBV reactivation has also been observed in occult B infection (HBcAb positive) and the optimal management of this group of patients requires special attention.

Abstract
Reactivation of hepatitis B is characterized by a sudden increase in hepatitis B virus (HBV) replication in a patient with prior evidence of resolved or inactive HBV infection. Although HBV reactivation can occur spontaneously, it usually occurs after chemotherapy, immunosuppression (organ transplantation) or an alteration in immune function (therapy for autoimmune disease, human immunodeficiency virus infection). The clinical presentation cases can vary, ranging from a subclinical, asymptomatic course to severe acute hepatitis and even death. Although reactivation of HBV is mainly found in HBsAg-positive patients, it can be observed in serologically recovered anti-hepatitis B core antibody (HBc)-positive, HBsAg-negative patients. Serum HBV DNA typically increases during immune suppression, followed by a disease flare and HBV DNA clearance following immune restoration after immune suppression is stopped. In organ transplant recipients, without immune reconstitution, high HBV DNA levels can lead to fibrosing cholestatic hepatitis related to the direct cytopathic effect of HBV. Several randomized, controlled trials and meta-analyses have shown that reactivation can be prevented by lamivudine prophylaxis. Screening for HBsAg and anti-HBc should be performed before beginning immunosuppressive treatment and routine prophylaxis is recommended in HBsAg-positive patients. The optimal duration of prophylaxis remains to be determined. In anti-HBc-positive patients with or without anti-hepatitis B surface antigen, alanine transaminase and HBV DNA levels should be closely monitored and antiviral therapy should be started when HBV reactivation is confirmed. The use of new more potent nucleos(t)ides analogues with lower resistance rates would seem to be logical; however, experience with these drugs in the prophylaxis and treatment of severe HBV reactivation is limited.

Abstract
We describe a case of reactivation of hepatitis D virus (HDV) in a patient treated with chemotherapy for a diffuse large B cell lymphoma despite lamivudine prophylaxis. This case suggests that previously cleared HDV should be considered when administering chemotherapy to patients with lymphoma.
