Abstract
INTRODUCTION Infection is a major complication in patients with chronic lymphocytic leukemia (CLL). Newly diagnosed patients are at high risk of developing infection caused by encapsulated bacteria, such as Streptococcus pneumoniae and Haemophylus influenzae. METHOD AND RESULTS However, once treatment is initiated, the spectrum of pathogens causing infection broadens, depending on the treatment regimens. With disease progression, cumulative immunosuppression occurs as a consequence of multiple treatment lines and the risk of infection further increases. On the other hand, the use of targeted therapies in the treatment of CLL have brought new risks of infection, with an increased incidence of invasive fungal diseases, particularly aspergillosis, in patients receiving Bruton kinase inhibitors. CONCLUSION In this article, we review the epidemiology of infection in patients with CLL, taking into account the treatment regimen, and briefly discuss the management of infection.

Fujita M, Kusumoto S, Ishii I, Iwata T, Fujisawa T, Sugiyama M, Hata A, Mizokami M. Cost-effectiveness of managing HBV reactivation in patients with resolved HBV infection treated with anti-CD20 antibody for B-cell non-Hodgkin lymphoma. Sci Rep 2022; 12:7365. [PMID: 35513395 PMCID: PMC9072369 DOI: 10.1038/s41598-022-10665-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2021] [Accepted: 04/11/2022] [Indexed: 11/24/2022] Open
Abstract
There is no universal recommendation for managing the reactivation of HBV in patients with resolved HBV infection treated with anti-CD20 monoclonal antibodies for B-cell non-Hodgkin lymphoma. This study compared the cost-effectiveness of two commonly used strategies: prophylactic anti-HBV nucleos(t)ide analog therapy (Pro NAT), and HBV DNA monitoring followed by on-demand antiviral therapy (HBV DNA monitoring). Using a decision tree model, the incremental cost-effectiveness ratio (ICER) expressed as cost per quality-adjusted life-year (QALY) gained was calculated. The threshold for cost-effectiveness was set at 5,000,000 JPY, equivalent to 45,662 USD. In a base–case analysis, HBV DNA monitoring was found to be more cost-effective based on the calculation of ICER as 132,048 USD per QALY, a value that far exceeds 45,662 USD. The same results were consistently obtained by a one-way deterministic sensitivity analysis, even after changing each parameter value within the predetermined range. A probabilistic sensitivity analysis with 10,000 simulations also revealed that HBV DNA monitoring is more cost-effective than Pro NAT in 96.8% of cases. Therefore, this study suggests that HBV DNA monitoring is an appropriate managing measure in Japan from a cost-effectiveness perspective.

Abstract
The hepatitis B core-related antigen (HBcrAg) is an unprecedented novel HBV biomarker that plays an essential role in reflecting covalently closed circular DNA (cccDNA) in chronic hepatitis B (CHB) because its levels correlate with intrahepatic cccDNA and serum HBV DNA. In this review, we describe the clinical application of serum HBcrAg in CHB patients, with a particular focus on new therapies targeting intrahepatic HBV replication. (1) HBcrAg can be detected in clinical cases where serum HBV DNA is undetectable during anti-HBV therapy. (2) A highly sensitive HBcrAg assay (iTACT-HBcrAg) may be useful for monitoring HBV reactivation, as an alternative to HBV DNA. (3) Decreased HBcrAg levels have been significantly associated with promising outcomes in CHB patients, reducing the risk of progression or recurrence of hepatocellular carcinoma. Additionally, we focus on and discuss several drugs in development that target HBV replication, and monitoring HBcrAg may be useful for determining the therapeutic efficacies of such novel drugs. In conclusion, HBcrAg, especially when measured by the recently developed iTACT-HBcrAg assay, may be the most appropriate surrogate marker, over other HBV biomarkers, to predict disease progression and treatment response in CHB patients.

Abstract
Hepatitis B virus (HBV) reactivation under systemic chemotherapy or immunosuppressive therapy is a serious complication among HBV-resolved patients. Some medications, such as more than 2 weeks of corticosteroid therapy, can influence HBV reactivation; therefore, screening tests that measure hepatitis B surface antigen (HBsAg), hepatitis B core antibody, and hepatitis B surface antibody before therapy are required. Additionally, because HBV reactivation has been reported in patients positive for HBsAg treated with immune checkpoint inhibitors (ICIs), the prophylactic administration of nucleos(t)ide analogues prior to administering ICIs is recommended for HBsAg-positive patients. Under these circumstances, highly sensitive novel biomarkers are expected to be used for the early diagnosis of HBV reactivation. A fully automated high-sensitivity HBsAg assay (detection limit: 5 mIU/ml) by Lumipulse HBsAg-HQ, with 10-fold higher sensitivity than that of conventional assays, is currently used. Furthermore, ultra-sensitive HBsAg assays using a semi-automated immune complex transfer chemiluminescence enzyme immunoassay (ICT-CLEIA; detection limit: 0.5 mIU/ml) have been developed. Recently, a fully automated, novel high-sensitivity hepatitis B core-related antigen assay (iTACT-HBcrAg; cut-off value: 2.1 Log U/mL) has been developed and reported. The utility of ICT-CLEIA and iTACT-HBcrAg for the diagnosis of HBV reactivation appears comparable to the use of HBV DNA. In this review, we provide the latest information related to medications that influence HBV reactivation and recently developed novel biomarkers that predict and monitor HBV reactivation.

Abstract
Purpose Hepatitis B virus reactivation (HBVr) in patients with gastrointestinal stromal tumors (GISTs) have not been sufficiently characterized. This study aimed to review the possible mechanism of HBVr induced by imatinib and explore appropriate measures for patient management and monitoring. Methods The clinical data of GIST patients who experienced HBVr due to treatment with imatinib at Xiangya Hospital (Changsha, Hunan, China) were retrospectively analyzed. A literature review was also conducted. Results Five cases were analyzed, including 3 cases in this study. The average age of the patients was 61.8 y, with male preponderance (4 of 5 vs. 1 of 5). These patients received imatinib as adjuvant treatment (n=4) or as neoadjuvant treatment (n=1). Primary tumors were mostly located in the stomach (n=4) or rectum (n=1). High (n=3) or intermediate (n=1) recurrence risk was categorized using the postoperative pathological results (n=4). Imatinib was then started at 400 (n=4) or 200 mg (n=1) daily. Patients first reported abnormal liver function during the 2th (n=1),6th (n=3), or 10th (n=1) month of treatment with imatinib. Some patients (n=4) discontinued imatinib following HBVr; notably, 1 month after discontinuation, 1 patient experienced HBVr. Antivirals (entecavir n=4, tenofovir n=1), artificial extracorporeal liver support (n=1), and liver transplant (n=1) were effective approaches to treating HBVr. Most patients (n=3) showed favorable progress, 1 patient underwent treatment, and 1 patient died due to severe liver failure induced by HBVr. Conclusions Although HBVr is a rare complication (6.12%), HBV screening should be conducted before starting treatment with imatinib in GIST patients. Prophylactic therapy for hepatitis B surface antigen positive patients, prompt antiviral treatment and cessation of imatinib are also necessary.

Abstract
INTRODUCTION The purpose of this study is to clarify the clinical features of temozolomide (TMZ)-related hepatitis B virus (HBV) reactivation and to identify HBV reactivation predictive factors. METHOD We retrospectively reviewed the clinical course of 145 patients newly diagnosed or with recurrent malignant glioma treated with TMZ. Before treatment, we screened patients for HB surface antigen (HBsAg) positivity (HBV carrier) and HBsAg negativity. Patients were also screened for antibody for HB core antigen (anti-HBc) positivity and/or for HB surface antigen positivity (resolved HBV infection). The patients were monitored by HBV DNA, alanine, and aspartate aminotransaminase during and after the completion of TMZ. HBV carriers and those with resolved HBV infections with HBV reactivation received preemptive entecavir treatment. In those with resolved HBV infections, we analyzed clinical characters for the predictive factors for HBV reactivation. RESULTS In one of two HBV carriers, HBV DNA turned positive 8 months after the completion of TMZ and entecavir. In four (16.7%) of 24 resolved HBV infections, HBV DNA turned detectable at completion of concomitant radiation and TMZ or during monthly TMZ. HBV DNA turned negative with entecavir in all patients without liver dysfunction. In resolved HBV infections, those with a high anti-HBc titer had significantly higher incidence of HBV reactivation than those with low anti-HBc titers (60% vs. 5.3%: p = 0.018). CONCLUSION Screenings, monitoring, and preemptive entecavir were important for preventing TMZ-related HBV reactivations. Anti-HBc titers could be the predictive markers for HBV reactivation in the those with resolved HBV infections.

Abstract
Various chemotherapy regimens are used to treat patients with diffuse large B-cell lymphoma (DLBCL). However, treatment-related toxicity with a focus on infectious disease has not been fully reviewed. Several phase 3 trials have demonstrated different rates of febrile neutropenia (FN) between regimens (e.g. dose-adjusted (DA) EPOCH-R vs. R-CHOP). With heterogeneous patient characteristics, a combination regimen of lenalidomide or ibrutinib with R-CHOP exhibited promising efficacy with moderate infectious toxicity. While R-bendamustine is feasible for patients who don't tolerate other forms of chemotherapy, clinical data indicate increased opportunistic infections under prolonged lymphopenia. The usefulness of prophylactic antibiotics/antifungal agents in DLBCL patients is controversial owing to shorter and less severe neutropenia than with the induction regimen for acute leukemia or hematopoietic stem-cell transplantation. Prophylactic granulocyte-colony stimulating factor is recommended for intensive regimens such as DA-EPOCH-R, R-DHAP, or R-ICE. Regardless of multiple studies about FN incidence, studies focusing on microbiologic events are limited, and further investigations are warranted.

Abstract
Hepatitis B virus (HBV) is a global disease with significant morbidity and mortality. Worldwide, ~257 million people are chronically infected with HBV, defined as having a positive hepatitis B surface antigen, but millions more have prior HBV exposure indicated by positive hepatitis B core antibody. Reactivation of hepatitis B implies a sudden increase in viral replication in a patient with chronic HBV infection or prior HBV exposure. Hepatitis B virus reactivation (HBVr) can occur spontaneously, but it is more commonly triggered by immunosuppressive therapies for cancer, immunologic diseases, or transplantation. Elimination of hepatitis C virus (HCV) in HBV-HCV coinfected individuals treated with direct-acting antivirals (DAAs) has also been identified as an important cause of HBVr. Hepatitis B virus reactivation is an underappreciated but important complication of common medical therapies that can delay treatment or result in clinical episodes of hepatitis, hepatic failure, or death. In this review, factors associated with HBVr, particularly medication-related risks, are explored. We review data involving rituximab and ofatumumab, doxorubicin, corticosteroids, tumor necrosis factor antagonists, tyrosine kinases, bortezomib, hematologic stem cell transplantation, and DAAs for HCV treatment. In addition, we discuss screening strategies, choice of antiviral prophylaxis, and the optimal duration of therapy for HBVr. With additional awareness, screening, and appropriate antiviral therapy, it is expected that most cases of HBVr can be prevented.

Abstract
AIM Longitudinal data of the reactivation of hepatitis B virus (rHBV) and serial serological markers or HBV-DNA has been limited. This study aimed to investigate the temporal course of rHBV development in rheumatoid arthritis (RA) patients undergoing long-term rituximab therapy. METHODS The occurrence of rHBV was examined in 157 RA patients during rituximab therapy. Serum levels of HBV surface antigen (HBsAg), HBV core antibody (HBcAb), and HBsAb were determined by electrochemiluminescence immunoassays, and viral loads by real-time polymerase chain reaction assay. RESULTS Among 157 patients undergoing rituximab therapy, 103 (65.6%) were HBsAg-negative and HBcAb-positive. Before rituximab therapy, 20 (19.4%) of these 103 patients were HBsAb-negative, while 83 (80.1%) were HBsAb-positive. Five (20%) HBsAb-negative patients developed rHBV after rituximab therapy. Among 83 HBsAb-positive patients, 4 (4.8%) developed rHBV. Among 9 patients with rHBV, 7 (77.7%) exhibited HBsAg seroreversion. Significant decline of HBsAb titers (mean ± SD, 296.0 ± 417.3 mIU/mL at baseline vs 187.0 ± 332.5 mIU/mL after rituximab therapy, P < 0.001) was observed in HBsAg-/HBsAb + patients. All HBsAg-negative patients who developed rHBV during rituximab therapy were characterized by baseline HBsAb titers < 100 mIU/mL and negative HBsAb at the time of rHBV. HBsAb positivity was an independent protective factor for rHBV (hazards ratio: 0.14, 95% CI: 0.03-0.62, P = 0.009). CONCLUSION Baseline HBsAb positivity was a significant protective factor for rHBV in HBsAg-negative, HBcAb-positive RA patients receiving rituximab therapy.

Abstract
Chronic active hepatitis B infection (HBV) has been implicated in lymphomagenesis of non-Hodgkin lymphoma (NHL). Treatment of cancer including NHL with chemotherapy or immunotherapy can lead to HBV reactivation in previously infected patients. Serological testing of HBV prior to initiation of this therapy is recommended by several national and international medical agencies and expert panels. Patients with positive hepatitis B surface antigen (HBsAg) and anti-hepatitis B core antibody (anti-HBc ab) need to start antiviral therapy with entecavir or tenofovir prior to initiation of chemotherapy or immunotherapy and continue this treatment for 6 to 12 months after completion of cancer therapy to avoid late HBV reactivation. Monitoring of HBV DNA viral load and liver function tests should be done during cancer therapy in infected patients. Hepatitis B infection vaccination resulted in decreases prevalence of HBV virus carriers and decreased incidence of virus-induced malignancies.

Risk of HBV reactivation in patients with B-cell lymphomas receiving obinutuzumab or rituximab immunochemotherapy. Blood 2018; 133:137-146. [PMID: 30341058 DOI: 10.1182/blood-2018-04-848044] [Citation(s) in RCA: 83] [Impact Index Per Article: 13.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2018] [Accepted: 10/02/2018] [Indexed: 02/06/2023] Open
Abstract
Risk of hepatitis B virus (HBV) reactivation was assessed in B-cell non-Hodgkin lymphoma (NHL) patients with resolved HBV infection (hepatitis B surface antigen negative, hepatitis B core antibody positive) who received obinutuzumab- or rituximab-containing immunochemotherapy in the phase 3 GOYA and GALLIUM studies. HBV DNA monitoring was undertaken monthly to 1 year after the last dose of study drug. In case of HBV reactivation (confirmed, HBV DNA ≥29 IU/mL), immunochemotherapy was withheld and nucleos(t)ide analog treatment (preemptive NAT) started. Immunochemotherapy was restarted if HBV DNA became undetectable or reactivation was not confirmed, and discontinued if HBV DNA exceeded 100 IU/mL on NAT. Prophylactic NAT was allowed by investigator discretion. Among 326 patients with resolved HBV infection, 27 (8.2%) had HBV reactivation, occurring a median of 125 days (interquartile range, 85-331 days) after the first dose. In 232 patients without prophylactic NAT, 25 (10.8%) had HBV reactivation; all received preemptive NAT. Ninety-four patients received prophylactic NAT; 2 (2.1%) had HBV reactivation. No patients developed HBV-related hepatitis. On multivariate Cox analysis, detectable HBV DNA at baseline was strongly associated with an increased risk of reactivation (adjusted hazard ratio [HR], 18.22; 95% confidence interval [CI], 6.04-54.93; P < .0001). Prophylactic NAT was strongly associated with a reduced risk (adjusted HR, 0.09; 95% CI, 0.02-0.41; P = .0018). HBV DNA monitoring-guided preemptive NAT was effective in preventing HBV-related hepatitis during anti-CD20-containing immunochemotherapy in B-cell NHL patients with resolved HBV infection. Antiviral prophylaxis was also effective and may be appropriate for high-risk patients. These trials were registered at www.clinicaltrials.gov as NCT01287741 (GOYA) and NCT01332968 (GALLIUM).

Abstract
Infections remain a threat for patients with haematological malignancies. In accordance with the European Hematology Association roadmap we provide a concise overview regarding the most relevant current challenges in infectious diseases for haematologists. These include bacterial infections and the need for antibiotic stewardship as well as infections with community-acquired respiratory viruses, infections in patients receiving targeted therapies, re-activations of latent infections and vaccination strategies. The following review intends to summarise the most relevant information for clinicians currently caring for patients with haematological malignancies. Recommendations given are based on the guidelines published by the Infectious Diseases Working Party of the German Society of Haematology and Medical Oncology.

Abstract
BACKGROUND Hepatitis B virus (HBV) reactivation in patients with resolved HBV infection (HBsAg negative, antiHBc positive) is uncommon, but potentially fatal. The role of HBV prophylaxis in this setting is uncertain. The aim of this study was to compare the efficacy of tenofovir disoproxil fumarate (TDF) prophylaxis versus close monitoring in antiHBc-positive, HBsAg-negative patients under treatment with rituximab (RTX)-based regimens for hematologic malignancy. METHODS PREBLIN is a phase IV, randomized, prospective, open-label, multicenter, parallel-group trial conducted in 17 hospitals throughout Spain. Anti-HBc-positive, HBsAg-negative patients with undetectable HBV DNA were randomized to receive TDF 300 mg once daily (Group I) or observation (Group II). The primary endpoint was the percentage of patients showing HBV reactivation during 18 months following initiation of RTX treatment. Patients with detectable HBV DNA (Group III) received the same dose of TDF and were analyzed together with Group I to investigate TDF safety. RESULTS Sixty-one patients were enrolled in the study, 33 in the TDF treatment group and 28 in the observation group. By ITT analysis, HBV reactivation was 0% (0/33) in the study group and 10.7% (3/28) in the observation group (p = 0.091). None of the patients in either group showed significant differences in liver function parameters between baseline and the last follow-up sample. TDF was generally well tolerated and there were no severe treatment-related adverse events. CONCLUSION In patients with hematological malignancy and resolved hepatitis B infection receiving RTX-based regimens, HBV reactivation did not occur in patients given TDF prophylaxis.

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
While the epidemiologic association between hepatitis B virus (HBV) infection and diffuse large B-cell lymphoma (DLBCL) is established, little is known more than this epidemiologic evidence. We studied a cohort of 587 patients with DLBCL for HBV infection status, clinicopathologic features, and the immunoglobulin variable region in HBV surface antigen (HBsAg)-positive patients. Eighty-one (81/587, 13.8%) patients were HBsAg-positive. Compared with HBsAg-negative DLBCL, HBsAg-positive DLBCL displayed a younger median onset age (45 vs. 55 years), more frequent involvement of spleen or retroperitoneal lymph node (40.7% vs. 16.0% and 61.7% vs. 31.0% respectively, both p < 0.001), more advanced disease (stage III/IV: 76.5% vs 59.5%, p = 0.003), and significantly worse outcome (2-year overall survival: 47% versus 70%, p < 0.001). In HBsAg-positive DLBCL patients, almost all (45/47, 96%) amino acid sequences of heavy and light chain complementarity determining region 3 exhibited a high homology to antibodies specific for HBsAg, and the majority (45/50, 90%) of IgHV and IgLV genes were mutated. We conclude that 13.8% of DLBCL cases are HBV-associated in HBV-endemic China and show unique clinical features and poor outcomes. Furthermore, our study strongly suggests that HBV-associated DLBCL might arise from HBV antigen-selected B cells.

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
Obinutuzumab is a humanized, type II anti-CD20 monoclonal antibody designed for strong induction of direct cell death and antibody-dependent cell-mediated cytotoxicity. The Phase III GADOLIN trial tested the clinical efficacy of obinutuzumab plus bendamustine followed by obinutuzumab monotherapy in rituximab-refractory indolent non-Hodgkin lymphoma versus treatment with bendamustine alone. It demonstrated significantly longer progression-free survival for the obinutuzumab-containing regimen in this difficult to treat patient group. Based on the results of this trial, US FDA approval was most recently granted for obinutuzumab in the treatment of follicular lymphoma that has relapsed after or was refractory to a rituximab-containing regimen. This article summarizes the available data on chemistry, pharmacokinetics, clinical efficacy and safety of obinutuzumab in the treatment of indolent non-Hodgkin lymphoma.

Abstract
The proportion of hepatitis B virus (HBV) previously exposed patients who receive immunosuppressive treatment is usually very small. However, if these individuals are exposed to potent immunosuppressive compounds, the risk of HBV reactivation (HBVr) increases with the presence of hepatitis B surface antigen (HBsAg) in the serum. Chronic HBsAg carriers have a higher risk than those who have a total IgG anticore as the only marker of resolved/occult HBV disease. The loss of immune control in these patients may results in the reactivation of HBV replication within hepatocytes. Upon reconstitution of the immune system, infected hepatocytes are once again targeted and damaged by immune surveillance in an effort to clear the virus. There are different virological scenarios, and a wide spectrum of associated drugs with specific and stratified risk for the development of HBVr. Some of this agents can trigger a severe degree of hepatocellular damage, including hepatitis, acute liver failure, and even death despite employment of effective antiviral therapies. Currently, HBVr incidence seems to be increasing around the world; a fact mainly related to the incessant appearance of more powerful immunosuppressive drugs launched to the market. Moreover, there is no consensus on the length of prophylactic treatment before the patients are treated with immunosuppressive therapy, and for how long this therapy should be extended once treatment is completed. Therefore, this review article will focus on when to treat, when to monitor, what patients should receive HBV therapy, and what drugs should be selected for each scenario. Lastly, we will update the definition, risk factors, screening, and treatment recommendations based on both current and different HBV management guidelines.
