Abstract
Background The prevalence of occult hepatitis B infection (OBI) among Iranian liver transplant recipient patients has not been explored yet. The present study aimed to determine the OBI prevalence among Iranian liver transplant recipients. Methods This study encompassed 97 patients having undergone liver transplantation due to several clinical backgrounds in the Liver Transplantation Center, Tehran, Iran. After serological evaluation, two different types of PCR methods were applied for amplification of HBV DNA, followed by the direct sequencing of whole hepatitis B virus (HBV) surface genes. Results At the time of admission, none of the patients were positive for HBsAg. However, 24 (25%), 12 (12.3%), and 5 (5.1%) cases were positive for anti‐HBc, hepatitis C virus (HCV), and hepatitis delta virus (HDV) antibodies, respectively. Moreover, two males were positive for OBI (2.1%). Both were positive for anti‐HBc and negative for anti‐HBs, anti‐HCV, and anti‐HDV. HBV‐related cirrhosis was the underlying reason for their liver transplantation. HBsAg sequences revealed no amino acid substitution. Conclusions The prevalence of OBI in the Iranian liver transplantation patients was relatively low. Future longitudinal studies with a larger sample size are suggested to explore the significance of this clinical finding, including the reactivation of cryptic HBV DNA, in liver transplant subjects.

Hepatitis B Virus Infection in Patients Receiving Allogeneic Hematopoietic Stem Cell Transplantation. J Pers Med 2021; 11:jpm11111108. [PMID: 34834460 PMCID: PMC8619006 DOI: 10.3390/jpm11111108] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2021] [Revised: 10/20/2021] [Accepted: 10/25/2021] [Indexed: 01/12/2023] Open
Abstract
Considering a steady increase in the number of allogeneic hematopoietic stem cell transplantations (allo-HSCT) worldwide and the significant proportion of the world’s population that has been exposed to hepatitis B virus (HBV) infection, HBV reactivation following allo-HSCT remains an important issue for post-transplant morbidity and mortality. Antiviral prophylaxis can reduce HBV replication, severity of HBV-related hepatitis, and mortality; therefore, identification of patients at risk is crucial. It is recommended that all recipients and donors should be screened for active or prior HBV infection, including HBsAg, antiHBc, and antiHBs. Adoptive immunity transfer from the donor seems to have protective effects against HBV reactivation. Antiviral prophylaxis should be initiated in all HBsAg-positive patients. HBsAg-negative, antiHBc-positive patients remain at risk; therefore, antiviral prophylaxis should be considered if baseline serum HBV DNA is detectable. In HBsAg-negative, antiHBc-positive patients without detectable HBV DNA, close monitoring of viral load with an on-demand therapy is necessary. Entecavir or tenofovir rather than lamivudine are more appropriate for the emergence of lamivudine resistance. The treatment duration remains unclear, with 6- to 12-month therapy after cessation of immunosuppressive therapy commonly recommended. Here we review the updated evidence and recent recommendations regarding HBV reactivation in patients undergoing allo-HSCT for individualized therapy.

Abstract
BACKGROUND & AIM Hepatitis B reactivation related to the use of immunosuppressive therapy remains a major cause of liver-related morbidity and mortality in hepatitis B endemic Asia-Pacific region. This clinical practice guidelines aim to assist clinicians in all disciplines involved in the use of immunosuppressive therapy to effectively prevent and manage hepatitis B reactivation. METHODS All publications related to hepatitis B reactivation with the use of immunosuppressive therapy since 1975 were reviewed. Advice from key opinion leaders in member countries/administrative regions of Asian-Pacific Association for the study of the liver was collected and synchronized. Immunosuppressive therapy was risk-stratified according to its reported rate of hepatitis B reactivation. RECOMMENDATIONS We recommend the necessity to screen all patients for hepatitis B prior to the initiation of immunosuppressive therapy and to administer pre-emptive nucleos(t)ide analogues to those patients with a substantial risk of hepatitis and acute-on-chronic liver failure due to hepatitis B reactivation.

Abstract
A 93-year-old man was admitted with 1 week of frank jaundice and abdominal pain. His medical history included diffuse large B-cell lymphoma treated with rituximab and cyclophosphamide, hydroxydaunomycin, oncovin and prednisolone (R-CHOP) chemotherapy 10 months prior. His investigations revealed marked hyperbilirubinemia with a total bilirubin of 355 μmol/L, along with a 17-fold elevation in alanine transaminase and impaired hepatic synthetic function. He tested hepatitis B surface antigen (HBsAg) and hepatitis B surface antibody (HBsAb) negative, hepatitis B core antibody (HBcAb) positive and had elevated hepatitis B virus DNA level at 13 691 IU/L. This was in the setting of radiological evidence of suspected cirrhosis. He was later found to have tested positive for HBcAb and negative for HBsAg and HBsAb prior to chemotherapy, but had not received antiviral prophylaxis. He was diagnosed with fulminant hepatitis secondary to delayed hepatitis B reactivation in the setting of rituximab. Hepatitis B reactivation and the role of screening and antiviral prophylaxis in isolated HBcAb-positive patients is reviewed.

Abstract
INTRODUCTION Current guidelines recommend starting antiviral prophylaxis to prevent hepatitis B virus (HBV) reactivation in patients receiving immunosuppressive treatments (IST). The aim of this study was to compare the efficacy of entecavir (ETV) and tenofovir disoproxil fumarate (TDF) for prophylaxis. METHODS Patients, who were HBsAg and/or anti-HBc IgG positive and scheduled to receive IST for oncologic and hematologic diseases, were enrolled into the study. Those who were already receiving an antiviral treatment for HBV or had an associated HIV, hepatitis C, D were excluded. The remaining patients with a prophylaxis indication according to the AGA guideline were randomized to receive either ETV (0.5 mg/day) or TDF (245 mg/day). Prophylaxis was continued for 6-12 months after completion of IST. Patients were followed up for 1 year after completion of prophylaxis. The HBV reactivation rates and side effects of the drugs were compared. RESULTS The study group included 120 patients. There was no significant difference between the demographic data, viral serologic parameters and reactivation risk profiles of the ETV (n = 60) and TDF (n = 60) groups. Forty-one patients in the ETV and 36 in the TDF group completed the antiviral prophylaxis, and no HBV reactivation was observed. HBV reactivation was observed in 4 of 37 patients (10.8%) in the ETV group and 5 of 35 (14.3%) patients in the TDF group (including one with flare) during the follow-up after completion of prophylaxis. Ten patients in the ETV group (16.7%) and 14 patients (23.3%) in the TDF group experienced side effects (p = 0.77). One patient in the TDF group had to switch to ETV due to severe itchy, maculopapular rash-like lesions. CONCLUSIONS ETV and TDF had a similar efficacy in the prophylaxis of HBV reactivation in patients undergoing IST, with none of the patients experiencing reactivation.

Abstract
BACKGROUND AND AIM Cytokine storm has been reported in patients with coronavirus disease 2019 (COVID-19) due to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. We examine the incidence of acute on chronic liver failure (ACLF) in COVID-19 patients with pre-existing compensated chronic liver disease (CLD). METHODS From 20 Jan 2020 to 7 Feb 2020, we studied 140 consecutive COVID-19 patients admitted to either Fuyang Second People's Hospital (FYSPH), Anhui or the Fifth Medical Center of Chinese PLA General Hospital (PLAGH) in Beijing, China. Pre-existing CLD includes those with liver cirrhosis assessed by APRI/FIB-4 score and /or ultrasound; NAFLD as identified by either ultrasound or hepatic steatosis index with significant liver fibrosis and chronic hepatitis B (CHB) or hepatitis C (CHC) infection. The diagnosis, grading of severity and clinical management of COVID-19 patients complied to the guideline and clinical protocol issued by the China National Health Commission. All patients had liver function test at least twice weekly till discharge with full recovery or death. RESULTS In total, 3 had liver cirrhosis, 6 patients had CHB, 13 had NAFLD with significant liver fibrosis (one also had CHB). On admission, none had liver decompensation. COVID-19 disease progression was significantly less frequent in non-CLD patients (10/118 8.5%) than CLD patients (13/22 59.1%, p < 0.001). One patient with CLD had acute-on-chronic liver failure (ACLF). CONCLUSION Disease progression is significantly higher in those COVID-19 patients with CLD as compared to those with no CLD. ACLF can also occur in patient with pre-existing compensated CLD who had severe COVID-19.

Abstract
Improved management of chronic hepatitis B patients with oral nucleos(t)ide analogues has increased the number of these patients who are getting older and have other accompanying comorbidities. These comorbidities frequently require various immunosuppression treatments and/or cytotoxic chemotherapy. Not only the patients who are positive for HBsAg, but also the patients who are positive for isolated anti-HBc are at risk for hepatitis B reactivation during immunosuppression. Prophylactic antiviral treatment with oral nucleos(t)ide analogues with high genetic barriers can decrease the risks of HBV reactivation, HBV reactivation- associated hepatitis, and mortality in these patients. It is crucial to screen HBV markers in all of the patients who have to undergo immunosuppression, be administered prophylactic antiviral treatment in the high risk groups, and be monitored for HBV reactivation during and after immunosuppression and/or cytotoxic chemotherapy. This study summarizes the recommendations from the recently updated guidelines from Korea, United States, and Europe.

Abstract
IMPORTANCE Antiviral treatment is important in hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) comprehensive therapy. A high HBV DNA level is an independent risk factor for HBV-related HCC, but no quantifiable clinical index is available to date. OBJECTIVE To evaluate the feasibility and availability of the novel HBV DNA quantitation-time index (HDQTI), which includes HBV DNA quantitation and follow-up, to predict HBV-related HCC prognosis. DESIGN, SETTING, AND PARTICIPANTS This retrospective prognostic study of patients with HCC from multiple centers in China was performed from January 1, 2002, to December 31, 2016. The median follow-up time was 18 months, and the longest follow-up time was 147 months. Data analysis was performed from January 1, 2017, to December 31, 2018. MAIN OUTCOMES AND MEASURES Clinical characteristics, antitumor management, antiviral treatment, HDQTI scores, follow-up information, and overall survival were recorded and analyzed. A receiver operating characteristic curve and accompanying area under the curve were calculated for HDQTI. RESULTS A total of 842 patients (mean [SD] age, 61.80 [9.85] years; 513 [60.9%] male) were included in the study. Of all included patients, 734 received no antiviral therapy before diagnosis (no previous diagnosis of HBV infection), 43 underwent nonstandard antiviral therapy, and 65 received regular antiviral therapy. Compared with the group without antiviral treatment, the Barcelona Clinic Liver Cancer (BCLC) stage was earlier (A:B:C, 73.8%:26.2%:0% to 5.7%:65.5%:28.8%, P < .001), the mean (SD) tumor size was smaller (2.89 [1.26] to 7.56 [3.28] cm, P < .001), the ratio of baseline HBV DNA level of more than 105 copies/mL was lower (10.8% to 40.6%, P < .001), and the ratio of the α1-fetoprotein level more than 400 ng/mL was less (21.5% to 78.2%, P < .001) in the standard antiviral treatment group, whereas the nonstandard treatment group was between the 2 groups. Recurrence occurred in 39 of 109 BCLC stage A cases. Patients with HDQTI scores higher than 34 had high risk of recurrence; at this cutoff level, the sensitivity of the HDQTI was 76.9% and the specificity was 92.9%, with an area under curve of 0.928. Patients in various BCLC stages had similar trends in overall survival and HDQTI scores (BCLC stage A: HDQTI score <34, not applicable; HDQTI score ≥34, 44.0 months; 95% CI, 38.3-49.7 months; BCLC stage B: HDQTI score <34, 35.0 months; 95% CI, 33.3-36.7 months; HDQTI score ≥34, 17.0 months; 95% CI, 14.5-19.5 months; P = .002; BCLC stage C: HDQTI score <34, 18.0 months; 95% CI, 16.5-19.6 months; HDQTI scores ≥34, 10.0 months; 95% CI, 8.5-11.5 months; P = .005). CONCLUSIONS AND RELEVANCE The findings suggest that the HDQTI can be used as an independent prognostic indicator of recurrence in HBV-related HCC. Shorter follow-up intervals and accurate imaging evaluation are recommended in patients with HDQTI scores of 34 or higher.

Abstract
BACKGROUND There are limited data about the mortality and morbidity of patients with HBV flare related to immunosuppressive treatments (IST) in the third-generation antivirals era. Herein, we performed a multi-centric study in patients treated with entecavir (ETV) or tenofovir disoproxil fumarate (TDF) and evaluated their clinical course. METHODS The study group included patients who were referred to gastroenterology or infectious disease specialists at eight different hospitals in Turkey. HBV flare was defined as at least a threefold elevation in alanine aminotransferase (ALT) levels above the upper limit of normal range. The demographic data, IST protocol, virological markers, liver tests, international normalized ratio (INR), HBV DNA, reactivation risk profile according to AGA guideline, MELD and MELD-Na scores were retrospectively evaluated. The primary aim of the study was to determine the liver-related mortality, including transplantation, at 12 weeks and factors predicting it. Secondary aims were to compare ETV and TDF with respect to mortality and time to ALT, bilirubin normalization and HBV DNA undetectability. RESULTS The study group included 40 patients (29 males, mean age: 57 ±12 years). Twenty-five patients (62.5%) had a high risk of reactivation. Twenty-six patients received TDF and 14 patients received ETV treatment. Eight (20%) patients developed acute liver failure and one patient (2.5%) underwent living donor liver transplantation. Seven patients died due to liver-related complications, revealing a mortality rate of 17.5%. In multivariate analysis, total bilirubin levels at the onset, ALT levels and delta-MELD score at the first week were the independent risk factors for liver related mortality (HR: 1.222, 1.003, 1.253 and 95% CI: 1.096, 1.362; 1.001, 1.004 and 1.065, 1.470, respectively). There was no significant difference between the TDF and ETV groups with respect to time to normalize ALT and bilirubin levels, HBV DNA undetectability and mortality rates (16% and 21.4%, respectively). CONCLUSIONS HBV flare associated with IST has a high mortality in the third-generation antivirals era. High total bilirubin at the onset and high ALT and delta-MELD score at the first week predict poor prognosis.

Abstract
Hepatitis B viral (HBV) reactivation in the immunosuppressed is a significant problem even in patients who have achieved serological clearance due to the persistence of HBV as cccDNA. HBV reactivation will continue to pose a significant healthcare burden given the high prevalence of HBV and increasing use of immunosuppressants. Screening of hepatitis B surface antigen, antibody to Hepatitis B core antigen antibody and HBV DNA levels should be done routinely in all patients planned for significant immunosuppressant use. We aimed to examine the factors affecting reactivation risk. This depended on HBV disease status, the underlying disease requiring immunosuppression, and the specific immunosuppressive regime. While antiviral prophylaxis can prevent reactivation, it increases cost and still has risk of delayed reactivation after stopping antivirals and close follow-up and on-demand treatment is a good alternative for patients at risk of reactivation.

Abstract
Hepatitis E virus infection is usually a self-limited disease. However, during the last years there has been growing evidence for prolonged and chronic infection occurring in patients with immunosuppression. Also patients with malignant and rheumatic diseases have been identified to be at risk for chronic hepatitis E. However, their course and prognosis are not well characterized and there have been no reports of hepatitis E virus infection in patients with gynecological cancer. Here, we report three Caucasian females with breast and ovarian cancers presenting with elevation of aminotransferase levels during anticancer treatment. Although only few or no clinical hints suggested hepatitis E virus infection, the diagnosis of hepatitis E virus infection was confirmed by seroconversion, which might occur with some delay, and/or by polymerase chain reaction. While two patients had a self-limited course, the third patient with a high-risk oncological constellation required ribavirin in order to resume chemotherapy. These cases highlight the need for hepatitis E virus testing in patients with gynecological cancer and elevated aminotransferase levels. Further, these cases show that in selected high-risk patients, ribavirin treatment may be necessary based on the decision of a multidisciplinary team.

Abstract
Aim: This case report suggests proper management of patients co-infected with both HCV and TB. Patients & methods: A 77-year-old female patient visited a primary care physician for a routine follow-up because she had past history of HCV in 2011, but she was successfully treated with interferon-therapy. She experienced HCV relapse in 2016 but did not respond to sofosbuvir and ribavirin and it was later on confirmed that she had TB which made the treatment of HCV more challenging. Results: This is the first evidence that highlights sofosbuvir, daclatasvir and ribavirin as an optimal treatment regimen for patients co-infected with TB. Furthermore, it is necessary to treat TB before initiating HCV treatment because of risk of hepatotoxicity. Conclusion: Co-infection of TB in HCV patients alters treatment response toward nucleotide analog inhibitor, sofosbuvir, an approved anti-HCV drug with high rate of sustained virological response.

Abstract
Although well described in the 1960s, liver toxicity secondary to radiation therapy, commonly known as radiation-induced liver disease (RILD), remains a major challenge. RILD encompasses two distinct clinical entities, a 'classic' form, composed of anicteric hepatomegaly, ascites and elevated alkaline phosphatase; and a 'non-classic' form, with liver transaminases elevated to more than five times the reference value, or worsening of liver metabolic function represented as an increase of 2 or more points in the Child-Pugh score classification. The risk of occurrence of RILD has historically limited the applicability of radiation for the treatment of liver malignancies. With the development of 3D conformal radiation therapy, which allowed for partial organ irradiation based on computed tomography treatment planning, there has been a resurgence of interest in the use of liver irradiation. Since then, a large body of evidence regarding the liver tolerance to conventionally fractionated radiation has been produced, but severe liver toxicities has continued to be reported. More recently, improvements in diagnostic imaging, radiation treatment planning technology and delivery systems have prompted the development of stereotactic body radiotherapy (SBRT), by which high doses of radiation can be delivered with high target accuracy and a steep dose gradient at the tumor - normal tissue interface, offering an opportunity of decreasing toxicity rates while improving tumor control. Here, we present an overview of the role SBRT has played in the management of liver tumors, addressing the challenges and opportunities to reduce the incidence of RILD, such as adaptive approaches and machine-learning-based predictive models.

Abstract
Patients with chronic hepatitis B infection are at risk of viral reactivation when treated by immuno- or chemotherapy, with potentially serious or even fatal consequences. This article proposes an overview on screening strategies and antiviral treatment recommendations for oncology patients. We have learned in hematology that reactivations are commun with rituximab and prophylactic treatment is recommanded for any patient who has been in contact with the virus. The risk appears to be lower with cytotoxics but has been far less studied. The recommandations are not formally consensual and upcoming studies will help to establish clearer practice guidelines.

Abstract
In 2016, the US Food and Drug Administration issued a warning about the risk of hepatitis B virus (HBV) reactivation in some patients receiving direct-acting antiviral (DAA) therapy for hepatitis C virus (HCV) infection. HBV reactivation can occur soon after the start of DAA therapy; thus, monitoring liver enzymes during DAA therapy is important in patients at risk. The clinical outcomes of HBV reactivation in this patient population may resemble the outcomes seen in immunosuppressed patients receiving chemotherapy. Each drug combination regimen has demonstrated risk for HBV reactivation and, therefore, contains a black box warning stating that all HCV-infected patients pending treatment should be tested for evidence of current or prior infection with HBV before initiating treatment. Both the American Association for the Study of Liver Diseases and the European Association for the Study of the Liver guidelines have been updated accordingly.

Abstract
Hepatitis B virus (HBV) reactivation during or after chemotherapy in patients with breast cancer has become a remarkable clinical problem. Prophylactic nucleos(t)ide analogues (NAs) are recommended for patients with breast cancer who are hepatitis B surface antigen (HBsAg) positive before chemotherapy. We performed an up-to-date meta-analysis to compare the efficacy of prophylactic lamivudine use with nonprophylaxis in HBsAg-positive breast cancer patients undergoing chemotherapy. PubMed, the Cochrane Library and China National Knowledge Infrastructure (CNKI) databases were searched for relevant articles until June 2016. Eligible articles comparing the efficacy of prophylactic lamivudine use with nonprophylaxis in HBsAg-positive breast cancer patients undergoing chemotherapy were identified. Eight studies which had enrolled 709 HBsAg-positive breast cancer patients undergoing chemotherapy were analysed. Lamivudine prophylaxis significantly reduced the rates of chemotherapy-associated hepatitis B flares in chronic hepatitis B in breast cancer compared with patients with nonprophylaxis (odds ratio [OR]=0.15, 95% confidence interval [CI]: 0.07-0.35, P<.00001). Chemotherapy disruption rates attributed to HBV reactivation in the prophylaxis groups were significantly lower than the nonprophylaxis groups (OR=0.17, 95% CI: 0.07-0.43, P=.0002). Patients with lamivudine prophylaxis had a higher risk for tyrosine-methionine-aspartate-aspartate (YMDD) motif mutations than patients with nonprophylaxis (OR=6.33, 95% CI: 1.01-39.60, P=.05). Prophylactic antiviral therapy management is necessary for HBsAg-positive breast cancer patients undergoing chemotherapy, in spite of high correlation with lamivudine-resistant HBV variants with YMDD motif mutations.

Abstract
The association of HBV infection with other hematopoietic diseases has been discussed previously. However, the clinical significance and clinical outcomes of HBV infection in AA patients have not been clarified. In this study, we sought to investigate the prevalence and related events of HBV in patients with AA who received immunosuppressive therapy. We retrospectively analyzed 245 patients with acquired AA. The HBsAg positivity rate was 14.69% in this group of AA patients. No significant difference was observed in the severity of AA patients with HBV infection and in those without (P = 0.6358). HBV reactivation occurred in 4.76% of HBsAg-positive patients who received ATG/ALG + CsA treatment without anti-viral prophylaxis. HBV-infected patients who received CsA alone did not develop reactivation. Patients with HBV reactivation showed favorable clinical outcomes, with no HBV-related deaths. There was no significant difference in overall probability of survival in patients with different HBV infection status (P = 0.8617). Given the low rate of reactivation and favorable outcomes after reactivation in AA patients, close monitoring of HBV DNA, hepatic function and patient immune status may be a more effective approach than routine prophylaxis for AA patients with HBV infection undergoing ATG/ALG + CsA treatment. Further studies are warranted to clarify the optimal time to initiate anti-viral treatment.

[PMID: 28730164 PMCID: PMC5444342 DOI: 10.1515/med-2017-0012] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2017] [Accepted: 03/22/2017] [Indexed: 11/15/2022] Open
Abstract
Liver injury is one of the most common complications in patients after kidney transplantation. Bicyclol tablets possess obvious anti-inflammatory and liver-protective functions. This study aimed to explore the clinical effect of preventive application of Bicyclol on drug induced liver injuries at an early stage after kidney transplantation. A total of 1600 patients who accepted kidney transplantations at our hospital from January 2009 to May 2015 were enrolled in this study, and divided into the prevention group (Bicyclol) and the control group (no hepatic protectors) based on whether or not hepatic protectors were regularly administered after the operation. The occurrence of liver injuries at an early stage after the operation and their influencing factors were analyzed. Total of 745 cases were included in the final analysis of which 82 developed liver injuries post-operation, with 22 in the prevention group (4.82%) as compared to 60 in the control group (20.76%) (P= 0.001). As compared to the control group, OR (95% CI) of the prevention group was 0.197 (0.116, 0.334) after revising HBsAg status, age and maintenance immunosuppression. Prophylactic application of Bicyclol as liver-protective treatment was a protective factor against drug induced liver injuries at an early stage after kidney transplantation.

Characteristics of escape mutations from occult hepatitis B virus infected patients with hematological malignancies in South Egypt. World J Hepatol 2017; 9:477-486. [PMID: 28396718 PMCID: PMC5368625 DOI: 10.4254/wjh.v9.i9.477] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/08/2016] [Revised: 08/02/2016] [Accepted: 12/14/2016] [Indexed: 02/06/2023] Open
Abstract
AIM To investigate the prevalence and virological characteristics of occult hepatitis B virus (HBV) infections in patients with hematological malignancies in South Egypt.
METHODS Serum samples were collected from 165 patients with hematological malignancies to monitor titers of HBV DNA, hepatitis B surface antigen (HBsAg), and antibodies to HBV core (anti-HBc) and surface antigens. Serum samples negative for HBsAg and positive for anti-HBc were subjected to nucleic acid extraction and HBV DNA detection by real-time polymerase chain reaction. DNA sequences spanning the S region were analyzed in cases with occult HBV infection. In vitro comparative study of constructed 1.24-fold wild type and S protein mutant HBV genotype D clones was further performed.
RESULTS HBV DNA was detected in 23 (42.6%) of 54 patients with hematological malignancies who were HBsAg negative, but anti-HBc positive, suggesting the presence of occult HBV infection. The complete HBV genome was retrieved from 6 occult HBV patients, and P120T and S143L were detected in 3 and 2 cases, respectively. Site directed mutagenesis was done to produce 1.24-fold genotype D clones with amino acid mutations T120 and L143. The in vitro analyses revealed that a lower level of extracellular HBsAg was detected by chemiluminescence enzyme immunoassay (CLEIA) with the clone containing T120 mutation, compared with the wild type or the clone with S143L mutation despite the similar levels of extracellular and intracellular HBsAg detected by Western blot. Southern blot experiments showed that the levels of intracellular HBV DNA were not different between these clones.
CONCLUSION Occult HBV infection is common in patients with hematological malignancies and associated with P120T and S143L mutations. 120T mutation impairs the detection of HBsAg by CLEIA.

Abstract
BACKGROUND Reactivation of hepatitis B virus during cancer chemotherapy for non-hematological tumors is not fully clear. AIM To evaluate the risk of hepatitis B virus reactivation in carriers of hepatitis B virus cancer patients treated with chemotherapy for solid tumors. METHODS Two hundred sixty-seven patients with solid tumors were consecutively enrolled: 13 (4.8%) were hepatitis B s-antigen positive, of whom 6 were documented inactive carriers and 7 had chronic liver disease. Thirty-two patients (12%) were hepatitis B s-antigen negative/hepatitis B c-antibody positive. Hepatitis B virus inactive carriers were followed every 3 months by alanine aminotransferases, hepatitis B virus-DNA; whereas hepatitis B virus occult carriers were followed every 3 months by alanine aminotransferases and hepatitis B s-antigen. RESULTS None of the 38 total patients with inactive or occult B infection who did not receive prophylaxis presented hepatitis B virus reactivation during the follow-up period. CONCLUSION This study suggests that, in hepatitis B s-antigen negative patients who undergo chemotherapy for solid tumors, hepatitis B and c-antibody screening results are not relevant to clinical decision and can be avoided. Larger studies are needed to establish whether the risk of reactivation of HBV during chemotherapy is negligible in this subset of patients and they could not be monitored for HBV reactivation.

Abstract
Hepatitis due to reactivation of hepatitis B virus (HBV) has been reported in patients treated with direct-acting antiviral (DAA) agents for chronic hepatitis C virus infection. We performed an observational study to determine the incidence of and factors associated with hepatitis in 327 patients receiving pan-oral DAA agents for HCV infections in areas endemic for HBV in China. Ten patients were positive for hepatitis B surface antigen (HBsAg), and 124 patients had occult HBV infection. HBV reactivation was determined by measuring HBV DNA and HBsAg status in serial serum samples collected every 2 weeks during DAA treatment and then every 4 weeks after treatment until week 12. In the total study population, 10 patients (3.1%) had hepatitis; 3 cases were associated with HBV reactivation (1 case not in the icteric phase, 1 case in the icteric phase, and 1 case with liver failure) and 7 from other causes. Testing positive for HBsAg before DAA treatment was a strong risk factor for developing hepatitis during treatment (hazard ratio, 15.0; P < .001).

Abstract
Since the registration of the first effective nucleoside analogue against the hepatitis B virus almost two decades ago, major progress has been made in the management of chronic hepatitis B infection. However, hepatitis B-related morbidity and mortality remain a major global health threat. This is partly due to the escalating costs and the decrease in compliance related to the need for prolonged therapy for most patients who cannot be "cured". New biomarkers such as quantitative hepatitis B surface antigen might help to determine if hepatitis B e antigen negative patients can be taken off nucleos(t)ide analogues. On the other hand, novel compounds that target the viral life cycle or modulate host immune response are in the pipeline. In the next few years, one should expect breakthrough advancement to be made leading to a "cure" for patients with chronic hepatitis B infection by inducing hepatitis surface antigen loss with or without the development of the hepatitis B surface antibody. In addition, attention and necessary actions should also be taken in patients with hepatitis B infection who are being treated with immunosuppressive therapy and direct anti-viral (DAAs) agents for hepatitis C infection to prevent hepatitis from hepatitis B reactivation.

Persistent risk of HBV reactivation despite extensive lamivudine prophylaxis in haematopoietic stem cell transplant recipients who are anti-HBc-positive or HBV-negative recipients with an anti-HBc-positive donor. Clin Microbiol Infect 2016; 22:946.e1-946.e8. [PMID: 27475741 DOI: 10.1016/j.cmi.2016.07.021] [Citation(s) in RCA: 24] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2016] [Revised: 07/08/2016] [Accepted: 07/16/2016] [Indexed: 02/08/2023]
Abstract
The overall rate of hepatitis B virus (HBV) reactivation was evaluated in a population of 373 haematological stem cell transplant (HSCT) patients treated with lamivudine (LMV) if they were anti-HBc-positive/HBV-DNA-negative recipients or if they were HBV-negative recipients with an anti-HBc-positive donor. The incidence of HBV reactivation was calculated in two groups of autologous (auto) or allogeneic (allo) HSCT patients who were stratified according to their HBV serostatus. The former group included 57 cases: 10 auto-HSCT and 27 allo-HSCT anti-HBc-positive recipients, two auto-HSCT and three allo-HSCT inactive carriers, and 15 allo-HSCT recipients with an anti-HBc-positive donor. Forty-seven (82.4%) patients in this group received LMV prophylaxis (the median (interquartile range, IQR) of LMV treatment was 30 (20-38) months). The second group consisted of 320 anti-HBc-negative auto-HSCT and allo-HSCT recipients with anti-HBc-negative donors. None of these patients received any prophylaxis. Two patients in the first group and two in the second group experienced reactivation of HBV infection, with an incidence of 3.5% (95% CI 0.4-12.1%) and 0.6% (95% CI 0.1-2.2%), respectively. Only one out of four reactivated patients was LMV-treated. The cumulative probability of HBV reactivation at 6 years from HSCT was 15.8% (95% CI 15.2-16.4%). Three of four viral isolates obtained from the HBV-reactivated patients harboured mutations in the immune-active HBsAg-region. In a HSCT population carefully evaluated for HBV prophylaxis, a risk of HBV reactivation persisted in the group of patients who were not LMV-treated. Only one LMV-treated patient experienced reactivation of HBV with a resistant HBV isolate.

Abstract
BACKGROUND Hepatitis B virus (HBV) has been associated with the development of non-Hodgkin lymphoma (NHL) and can be reactivated in patients being treated for NHL. METHODS Articles published between 2000 and 2015 that discussed an association between NHL and HBV, mechanisms of HBV induction of NHL, and HBV reactivation in patients with NHL were reviewed and the results compiled to help health care professionals better understand the risk of developing NHL in HBV-seropositive individuals, describe potential etiologies by which HBV infection may lead to lymphomagenesis, and highlight the recent medical literature with respect to the reactivation of HBV in the setting of NHL. RESULTS An association exists between HBV infection and NHL development. Immunosuppression due to HBV, chronic viral stimulation, and dysregulation of the immune system are possible ways in which lymphoma can develop in patients with HBV infection. All patients being treated with anti-CD20 antibodies or those from or living in HBV-endemic regions should be tested for hepatitis B surface antigen, core antibody, and surface antibody prior to initiating therapy. HBV DNA polymerase chain reaction (PCR) may also be useful in certain cases. Among HBV-seropositive patients or those with detectable HBV DNA, prophylaxis with an antiviral agent should be initiated for 1 year after NHL therapy. HBV DNA PCR monitoring should be undertaken each month during the course of treatment and every 3 months after treatment for a 1-year duration. CONCLUSIONS Health care professionals should become more comfortable treating these high-risk patients with NHL as they become more informed about potential lymphomagenesis and the reactivation of HBV.

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
UNLABELLED Awareness of cancer therapy-induced toxicities is important for all clinicians treating patients with cancer. Cancer therapy has evolved to include classic cytotoxic agents in addition to newer options such as targeted agents and catheter-directed chemoembolisation. Several adverse affects can result from the wide array of treatments including effects on the liver, pancreas, and biliary system that can be visualised on imaging. These complications include sinusoidal obstruction syndrome, fatty liver, pseudocirrhosis, acute hepatitis, pancreatitis, pancreatic atrophy, cholecystitis, biliary sclerosis, and biliary stasis. Many of these toxicities are manageable and reversible with supportive therapies and/or cessation of cancer therapy. The objective of this review is to discuss the imaging findings associated with cancer therapy-induced toxicity of the liver, biliary system, and pancreas. TEACHING POINTS • Cancer therapy can have adverse effects on the hepatobiliary system and pancreas. • Cancer therapy-induced toxicities can be visualised on imaging. • Knowledge of imaging changes associated with cancer therapy complications can improve treatment.

Abstract
BACKGROUND Nucleos(t)ide analogues reduce the incidence of hepatitis B virus (HBV) reactivation in cancer patients undergoing systemic cytotoxic chemotherapy but the experience of solid tumors remains limited. Aims. The aim of this study was to compare the efficacy of entecavir and lamivudine in the prophylaxis of HBV reactivation in solid tumor patients undergoing systemic cytotoxic chemotherapy. METHODS HBsAg seropositive patients undergoing systemic cytotoxic chemotherapy for solid tumors with prophylactic entecavir and lamivudine between January 2006 and June 2013 were retrospectively investigated. The incidence of HBV reactivation and outcome of the patients were analyzed. The risk factors of HBV reactivation were examined. RESULTS A total of 213 patients (entecavir group, 70 patients; lamivudine group, 143 patients) were evaluated. Less incidence of HBV reactivation was noticed in entecavir group than in lamivudine group (0% vs. 7.0%, P = 0.02). No HBV reactivation was noticed in the patients with a baseline HBV DNA level < 2000 IU/mL. A baseline HBV DNA level ≥ 2000 IU/mL, HBeAg, and lamivudine were significantly associated with HBV reactivation. Subgroup analysis of the patients with a baseline HBV DNA level ≥ 2000 IU/mL found that lamivudine was significantly associated with HBV reactivation. Most of the reactivation events were properly managed by using tenofovir disoproxil fumarate. The incidence of hepatitis during chemotherapy and disruption of chemotherapy was similar between patients using entecavir and lamivudine with a baseline HBV DNA level ≥ or < 2000 IU/mL. CONCLUSIONS A baseline HBV DNA level ≥ 2000 IU/mL, HBeAg, and lamivudine were the risk factors of HBV reactivation during systemic cytotoxic chemotherapy in solid tumor patients. Entecavir was superior to lamivudine in terms of less incidence of reactivation in the patients with a baseline HBV DNA level ≥ 2000 IU/mL. Both agents were equally efficacious in the patients with HBV DNA levels < 2000 IU/mL.

Abstract
Chronic hepatitis B virus (HBV) infection affects approximately 375 million people worldwide. Current antiviral treatment effectively controls, but rarely clears chronic HBV infection. In addition, a significant portion of chronic HBV infected patients are not suitable for currently available antiviral therapy, and still face higher risk for cirrhosis and hepatocellular carcinoma. The poorly understood pathogenesis of HBV infection is the main barrier for developing more effective treatment strategies. HBV has long been viewed as non-cytopathic and the central hypothesis for HBV pathogenesis lies in the belief that hepatitis B is a host specific immunity-mediated liver disease. However, this view has been challenged by the accumulating experimental and clinical data that support a model of cytopathic HBV replication. In this article we systematically review the pathogenic role of HBV replication in hepatitis B and suggest possible HBV replication related mechanisms for HBV-mediated liver injury. We propose that a full understanding of HBV pathogenesis should consider the following elements. I. Liver injury can be caused by high levels of HBV replication and accumulation of viral products in the infected hepatocytes. II. HBV infection can be either directly cytopathic, non-cytopathic, or a mix of both in an individual patient depending upon accumulation levels of viral products that are usually associated with HBV replication activity in individual infected hepatocytes.

Abstract
Several reports have emphasized the risk of hepatitis B virus (HBV) reactivation in patients with lymphoproliferative disorders undergoing cytotoxic treatment. To determine the prevalence of occult B infection (OBI) in a population with chronic lymphocytic leukemia (CLL) and management with universal prophylaxis (UP) in all patients undergoing chemoimmunotherapy or targeted prophylaxis (TP) in patients experiencing seroreversion during therapy, we analyzed 397 patients with CLL from our database. The prevalence of OBI in our patients with CLL was 8.6% (34 patients). When comparing patients with OBI/CLL with those with CLL, we did not find any statistical difference among clinical-biological parameters and time dependent endpoints except for a lower peripheral blood lymphocyte count in the OBI/CLL group (p = 0.036). From 2000 to 2010 careful follow-up and TP were adopted; two out of 10 patients (20%) showed seroreversion. From June 2010 we adopted UP during and 12 months after immunosuppressive treatment in all patients with CLL with OBI; no evidence of seroreversion was detected.

Preemptive adefovir versus lamivudine for prevention of hepatitis B reactivation in chronic hepatitis B patients undergoing chemotherapy. Hepatol Int 2015; 9:224-30. [PMID: 25788197 DOI: 10.1007/s12072-015-9612-6] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/24/2014] [Accepted: 02/10/2015] [Indexed: 12/19/2022]
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
<title>Abstract Since Wands et al. reported for the first time in 1975 the reactivation of the hepatitis B virus in hematologic disease patients who had been receiving chemotherapy, the efficacy of chemotherapy and immunosuppressants has improved. As a result, the frequency of the reactivation of hepatitis B is increasing. Reported herein is a case of a non-Hodgkin lymphoma patient in her 70s who was suspected to have had HBsAg negative/anti-HBs negative occult HBV infection. The patient experienced fulminant hepatitis caused by the reactivation of hepatitis B, and died three months after the R-CHOP regimen was completed. In the HBsAg negative plus HBV DNA-negative case, there were few instances of viral activation of HBV. In this case, antiviral therapy was needed when the patient was confirmed to have become HBV DNA positive through regular monitoring, but its necessity is often overlooked, unlike the preemptive antiviral treatment in the HBsAg positive cases.</p>

Abstract
AIM: To understand the impact of different initial hepatitis B virus (HBV) DNA copies on the efficacy and side effects of chemotherapy combined with antiviral therapy in tumor patients with hepatitis B.
METHODS: Eighty-seven tumor patients with HBV infection were randomly divided into two groups according to the initial HBV DNA copies: A and B. Group A included 44 patients with the initial HBV DNA copies ≥ 1 × 103 GE/mL, while group B included 43 patients with the initial HBV DNA copies < 1×103 GE/mL. All of the patients had been treated with antiviral therapy for one month before conventional chemotherapy and continued to receive antiviral therapy for three months after chemotherapy.
RESULTS: The Karnofsky performance status (KPS) score was significantly higher in group B than in group A. The short-term therapeutic effects were similar between groups A and B, while in terms of long-term efficacy, the disease progression and death risk at 6 mo after chemotherapy were significantly lower in group B than in group A. The rate of related side effects did not increase significantly during chemotherapy combined with antiviral therapy.
CONCLUSION: For tumor patients with HBV infection, chemotherapy combined with antiviral therapy is superior to chemotherapy alone in terms of improving the KPS score and side effects.

Abstract
BACKGROUND The prevalence of hepatitis B virus (HBV) infection is high in Asian countries. Little is known about outcome of leukemia in HBV infected patients in these regions. Hence, we conducted this study in two cohorts of patients. PROCEDURE We retrospectively evaluated mortality, reduction in dose intensity and duration of therapy (intensive phase and maintenance phase) in children with acute lymphoblastic leukemia (ALL) who developed HBV infection. Sixty-three patients with ALL were included in the retrospective cohort of the study. These were followed up for a minimum of 5 years. We prospectively investigated the prevalence of anti-HBc antibodies in 105 treatment naïve pediatric patients with ALL and negative for HbsAg. RESULTS Twenty of the 63 patients developed hepatitis, of which 10 were attributed to HBV. All the 10 patients with HBV hepatitis had significantly reduced dose intensity during maintenance therapy with an average delay in completion of therapy of 140 ± 83 days and also a high mortality (40%). In the prospective cohort of the study, 39% of treatment naive patients who were HBsAg negative were anti-HBc positive at presentation, possibly reflecting occult HBV infection. CONCLUSIONS HBV infection poses a serious problem in patients with ALL. Hence we propose that in India, in addition to screening for HBsAg, patients with leukemia should also be screened for anti-HBc. Improved hepatitis B vaccine coverage in the community under the universal immunization programme and introduction of HBV nucleic acid test (NAT) for blood donations should also help in addressing the problem.

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
Patients with hepatocellular carcinoma (HCC) often experience hepatic morbidity. Hepatitis B virus (HBV) reactivation is well documented as a serious hepatic morbidity during anti-cancer therapy. Reported rates of HBV reactivation in chronic carriers with HCC undergoing chemotherapy range from 4%-67%. Apart from chemotherapy, HBV reactivation has been increasingly identified in settings of hepatectomy and local ablation therapies. The rates of HBV reactivation vary with different levels of immunosuppression and depend on treatment, viral factors, and patient characteristics. The principal concern relating to reactivation is that a substantial proportion of patients with reactivation suffer from liver dysfunction during therapy, which often leads to disruption of planned, potentially life-prolonging treatments, adversely affecting the patients’ final outcome. The first step in the management of HBV reactivation is identification of patients at risk of reactivation by testing for HBV serology prior to commencing anti-cancer therapy. Although it is a serious complication, HBV reactivation is preventable with prophylactic anti-HBV drugs. Multiple publications have shown the benefit of prophylactic or preemptive antiviral therapy in this setting and justified such an approach before the start of therapy. Given the tumors and underlying cirrhosis, long-term use of antivirals with high potency and low risk of resistance is recommended in patients with HCC. This topic review will summarize the epidemiology, pathogenesis, and clinical issues related to HBV reactivation in HCC patients, and will discuss proper management against HBV reactivation during anti-cancer therapy for HCC.

Abstract
Occult hepatitis B infection (OBI), is characterized by low level hepatitis B virus (HBV) DNA in circulating blood and/or liver tissue. In clinical practice the presence of antibody to hepatitis B core antigen in hepatitis B surface antigen (HBsAg)-/anti-HBs-negative subjects is considered indicative of OBI. OBI is mostly observed in the window period of acute HBV infection in blood donors and in recipients of blood and blood products, in hepatitis C virus chronic carriers, in patients under pharmacological immunosuppression, and in those with immunodepression due to HIV infection or cancer. Reactivation of OBI mostly occurs in anti-HIV-positive subjects, in patients treated with immunosuppressive therapy in onco-hematological settings, in patients who undergo hematopoietic stem cell transplantation, in those treated with anti-CD20 or anti-CD52 monoclonal antibody, or anti-tumor necrosis factors antibody for rheumatological diseases, or chemotherapy for solid tumors. Under these conditions the mortality rate for hepatic failure or progression of the underlying disease due to discontinuation of specific treatment can reach 20%. For patients with OBI, prophylaxis with nucleot(s)ide analogues should be based on the HBV serological markers, the underlying diseases and the type of immunosuppressive treatment. Lamivudine prophylaxis is indicated in hemopoietic stem cell transplantation and in onco-hematological diseases when high dose corticosteroids and rituximab are used; monitoring may be indicated when rituximab-sparing schedules are used, but early treatment should be applied as soon as HBsAg becomes detectable. This review article presents an up-to-date evaluation of the current knowledge on OBI.

Abstract
BACKGROUND AND AIM The purpose of the present study was to determine whether lamivudine in combination with transarterial chemoembolization (TACE) could reduce hepatitis B virus (HBV) activation and improve the survival of patients with hepatocellular carcinoma (HCC). METHODS From July 2008 to October 2011, a total of 181 consecutive HBV-related HCC patients undergoing TACE were randomized to two groups (92: lamivudine, 89: control). Follow up was every 3 months. Primary and secondary end-points were time to progression (TTP) and overall survival (OS), respectively, both of which were evaluated by the Kaplan Meier technique and summarized by the hazard ratio. RESULTS The level of HBV-DNA became undetectable in 42 (45.6%) patients in the lamivudine group, compared with 10 (11.2%) in the control group (P < 0.001). The median TTP was 8.2 months in lamivudine group and 4.3 months in control group (P = 0.005), and lamivudine therapy was an independent protective factor related to TTP (P = 0.006). Moreover, 1-, 2-, and 3-year survival rates were 83%, 69%, and 58% in lamivudine group and 60%, 48%, and 48% in control group, respectively (P = 0.002). With multivariate Cox regression model, lamivudine therapy (P = 0.002) and α-fetoprotein (AFP) level (P = 0.003) were two independent predictors for OS. CONCLUSION Lamivudine therapy could reduce HBV activation and improve survival of HCC patients treated with TACE. Lamivudine therapy and AFP level are two independent factors affecting OS.

Abstract
INTRODUCTION Rituximab is a widely prescribed anti-CD20 mAb for the treatment of CD20(+) B-cell non-Hodgkin Lymphoma and many other immune mediated conditions. There is a well-described association between rituximab containing chemo-immunotherapy treatment and reactivation of the hepatitis B virus (HBV). This review summarizes the current literature surrounding rituximab-associated HBV reactivation. AREAS COVERED Herein, we review the literature detailing the risk of HBV reactivation in inactive carriers and those with resolved hepatitis. The clinical presentation and management of HBV reactivation are also discussed along with a summary of clinical trials evaluating antiviral prophylaxis. Finally, clinical recommendations are detailed. Data from clinical trials, observational studies, reviews, and meta-analyses available in the Medline database were included in this narrative review. EXPERT OPINION Screening should be performed in all patients prior to the administration of any type of anti-CD20 mAb therapy. Among those with positive screening serology, testing for hepatitis B e antigen or viral load by polymerase chain reaction is appropriate. In those patients with detectable HBV DNA, the decision regarding the use of antiviral prophylaxis or observation should be individualized.

Abstract
Hepatitis B virus (HBV) reactivation strongly affects the practice of physicians dealing with hematological malignancies. In this respect, in collaboration with the Italian Lymphoma Foundation we developed a descriptive study of the real-life approach of physicians caring for patients with these diseases. A questionnaire was designed to explore the perception of HBV reactivation-related issues. Fifty-nine Italian Lymphoma Foundation-affiliated institutions participated, and 504 questionnaires were sent out. Forty institutions (67.8%) returned 154 (30.5%) completed questionnaires. The largest majority (91.5%, 141/154) were aware of possible HBV reactivation as a consequence of immunosuppression. Most of the participants providing an answer (93.3%; 126/135) performed universal screening, and were aware of strategies for managing reactivation (96.4%, 132/137). Specialists treating lymphoma show a high level of awareness concerning the management of HBV reactivation under immunosuppression. However, uncertainties regarding the issue of HBV reactivation still emerge in this setting, and thus continuing collaborative effort between hepatologists and hematologists is necessary.

Abstract
BACKGROUND Recently, the reactivation during treatment with tumor necrosis factor (TNF) blockers has exceptionally been described in patients with hepatitis B virus (HBV) antigen-negative (HBsAg). The objective was to evaluate the influence of anti-TNF agents in patients with psoriasis and serology suggesting past hepatitis B state. METHODS The inclusion criteria were chronic plaque psoriasis treated with anti-TNF therapy, HBsAg-negative, and HBcAb-positive. We gathered the demographic data and type and duration of anti-TNF agent. Serum aminotransferase levels and HBV serologic status were requested at baseline and during follow-up. RESULTS We have included 13 patients (four women, nine men) (mean age of 62.1 years). The agent was etanercept in seven cases, infliximab in four patients, and adalimumab in the other two. The mean duration of TNF therapy was 28.6 months. None of them became HBsAg-positive. Neither signs nor symptoms of acute hepatitis were reported. CONCLUSION The management of HBsAg-negative patients is unresolved. Only nine cases of HBV reactivation during treatment with TNF blockers have been reported. Despite the low risk of reactivation in these patients, we recommend the monitoring of serum aminotransferase levels, HBsAb titers, HBsAg and, if possible, viral load.

Abstract
AIM: To estimate hepatitis B virus (HBV) infection testing rate in cancer patients before chemotherapy with a focus on HBV reactivation.
METHODS: A retrospective study was conducted from January 1, 2009 to June 30, 2010. Inclusion required that patients be naïve to cancer chemotherapy but have indications for it. Patients who did not receive chemotherapy for any reason were excluded. Important clinical information, such as the levels of HBV DNA and serological markers were collected. HBV reactivation was defined as an increase in serum HBV DNA to > 1 log higher than that of the pre-exacerbation baseline, or serum HBV DNA conversion from negative to positive. HBV DNA levels > 1000 copies/mL were defined as HBV DNA positive. The χ2 or Fisher’s exact test was used for analysis of categorized data. Multiple logistic regression analysis was used to estimate the odd ratio and 95%CI of the HBV screening rate.
RESULTS: Of 6646 patients, 5616 (84.5%) received chemotherapy. Only 17.1% of the cancer patients received pre-chemotherapy HBV testing (43.2% for hematological malignancies and 14.9% for solid tumors). Patients who had received rituximab therapy, had elevated aminotransferase levels, or had hematological malignancies were more likely to receive HBV testing. The prevalence of hepatitis B surface antigen (HBsAg) positivity was 13.4%. HBV reactivation (appearance of HBV DNA or an increase in HBV DNA levels by 1 log10) was observed in 33.1% (53/160) of the patients after chemotherapy. Among patients without prophylactic antiviral therapy, the reactivation rate was 43.9% (43/98) in the solid tumor group. Two reactivation cases occurred in patients who were HBsAg negative, but positive for hepatitis B core antibody. HBV reactivation was more likely to occur in patients with lymphoma, high levels of HBV DNA, or hepatitis B e antigen, and in men.
CONCLUSION: Less than 20% of patients received HBV testing before chemotherapy. HBV reactivation would have occurred in about 50% of infected patients with solid tumors without antiviral prophylaxis.
