rituximab hepatitis b reactivation

Higher risks of infection are associated with some targeted drugs used to treat solid organ and hematological malignancies, and an individual patient's risk of infection is strongly influenced by underlying diseases and concomitant or prior treatments. This review focuses on risk levels and specific suggestions for management, analyzing groups of agents associated with a significant effect on the risk of infection. Due to limited clinical experience and ongoing advances in these therapies, recommendations may be revised in the near future...

We conducted a nationwide retrospective analysis of 116 hepatitis B virus (HBV) surface antigen (HBsAg)-positive patients with diffuse large B-cell lymphoma (DLBCL) and 278 HBsAg-negative patients with DLBCL, as a control cohort, who received rituximab-containing regimens as an induction chemotherapy at 30 Japanese medical centers between January 2004 and December 2014. Hepatitis was defined as an absolute serum alanine aminotransferase (ALT) level of ≥100 U/L. HBV reactivation-related hepatitis was defined as hepatitis with an absolute serum HBV DNA level of ≥3...

STUDY OBJECTIVE: To evaluate a surveillance protocol in managing the risk of hepatitis B virus (HBV) reactivation among lymphoma patients with resolved HBV infection receiving rituximab. DESIGN: Prospective, single-arm study. SETTING: National Cancer Centre, Singapore. PATIENTS: Lymphoma patients with resolved HBV infection and scheduled to receive rituximab-based treatment. INTERVENTION: Close monitoring of HBV DNA levels, ie...

OBJECTIVE: Hepatitis B reactivation (HBr) is strongly associated with rituximab therapy. Guidelines advise hepatitis B screening and use of preventive nucleoside analogue (NA) in patients at risk. In this study, we examined screening trends, post-screening interventions and outcomes in patients receiving rituximab in light of recommendations. DESIGN: Retrospective, observational study. SETTING: Single, tertiary care centre in the USA. PARTICIPANTS: Patients receiving rituximab from January 2005 to December 2017...

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 prevention of hepatitis B virus (HBV) reactivation during rituximab treatment for diffuse large B-cell lymphoma (DLBCL) is important in the HBV-endemic area. This population-based study examines the impact of antiviral prophylaxis for DLBCL patients with HBV infections. We identified 3702 adult patients with newly diagnosed DLBCL between 2011 and 2015 receiving R-CHOP, R-CVP, CHOP or CVP from the Taiwan Cancer Registry. We further stratified them into three groups: HBsAg-negative patients (HBV-negative, N = 2921), HBV carriers who received antiviral prophylaxis (HBV + Px, N = 711), and HBV carriers who did not receive antiviral prophylaxis (HBV + No Px, N = 70)...

Over the last two decades, rituximab (RTX) has played an important role in the treatment of some lymphoproliferative malignancies and immune-mediated diseases. RTX administration is generally safe and well-tolerated, but side effects including late-onset neutropenia, hypogammaglobulinemia, hepatitis B reactivation and rare cases of progressive multifocal leukoencephalopathy have been observed after its administration. Although there are no absolute contraindications regarding its use in people living with HIV (PLWH), the prescription of this drug has been principally limited in patients with oncohematological diseases...

Objective We started an information technology (IT) system that encodes the medical treatment status of hepatitis B virrus (HBV) with a 9-digit number, automatically checks for inappropriate situations occurring due to immunosuppression and chemotherapy that do not comply with the flowchart of the hepatitis B countermeasure guideline, and promotes correct HBV medical treatment in our hospital. We conducted a prospective study of HBV reactivation using this system. Methods Among 21,607 cases that were managed using this system, 1,206 patients who were HBs antigen-negative, HBc antibody- and/or HBs antibody-positive and in whom HBV DNA quantification was performed two times or more were examined for the occurrence of HBV reactivation...

A 54-year-old woman underwent chemotherapy including rituximab and autologous peripheral blood stem cell transplantation (auto-PBSCT) for diffuse large B-cell lymphoma. Before the treatment, she exhibited a resolved hepatitis B virus (HBV) infection. She was diagnosed with HBV reactivation based on positive serum HBV-DNA test results, 55 months after her last treatment. Subsequently, he was treated with tenofovir alafenamide fumarate (TAF) therapy and her liver function improved. Patients undergoing chemotherapy including rituximab and auto-PBSCT are at a high risk of HBV reactivation...

OBJECTIVES: Hepatitis B (HBV) is a common comorbidity among rheumatic patients. The prevalence of HBV infection and the rate of reactivation remain unclear. The literature data suggested a higher risk in chronic than in past infection. Currently, the literature data are mostly focused on anti-TNF and rituximab. This retrospective observational study aimed to analyse the prevalence of HBV infection and the risk of viral reactivation in a population of rheumatic patients undergoing anti-TNF and non-anti-TNF agents...

BACKGROUND: Prophylaxis with nucleos(t)ide analogue (NA) is recommended to prevent hepatitis B virus (HBV) reactivation in hepatitis B surface antigen (HBsAg)-positive patients receiving rituximab-based B cell depletion therapy. However, little is known about the risk of clinical relapse following withdrawal of NA. PATIENTS: and Methods: We retrospectively analyzed 77 non-cirrhotic, HBsAg carriers with haematological malignancies who received rituximab-containing chemotherapy...

Hepatitis B virus (HBV) reactivation can be a serious complication for patients with chronic or resolved HBV infection when treated with biologics. For HBsAg-positive patients receiving biologics, the risk of HBV reactivation is moderate to high. HBsAg-negative/anti-HBc positive patients are at lower risk of HBV reactivation than HBsAg-positive patients. However, patients taking anti-CD20 agents, such as rituximab, have high risk of HBV reactivation (>10%), so antiviral prophylactic therapies are required...

Hepatitis B reactivation (HBR) is a complication of immunosuppression associated with significant morbidity and mortality. To further complicate interpretation of hepatitis B serologies, false positivity can occur in patients with recent intravenous immunoglobulin exposure. This scenario is not well recognized and may lead to inappropriate prescribing of HBR prophylaxis.

BACKGROUND & AIMS: Quantification of anti-HBs and anti-HBc predicts the risk of HBV reactivation (HBVr) in lymphoma patients receiving rituximab treatment. However, it remains unclear whether the quantification is predictive of HBVr in leukemia patients undergoing immunosuppression. METHODS: and patients: Clinical and laboratory data of the leukemia patients with resolved HBV infection diagnosed between January 2013 and March 2018 were retrospectively collected...

Nowadays, intensive immunosuppressive therapy including rituximab is commonly used prior to kidney transplantation (KT), raising concerns over hepatitis B virus (HBV) reactivation among hepatitis B surface antigen (HBsAg)-negative and anti-hepatitis B core (HBc)-positive KT recipients. Recent practice guidelines suggested watchful monitoring or antiviral prophylaxis for the first 6-12 months, the period of maximal immunosuppression. However, the actual risk for HBV reactivation, and whether short-term antiviral therapy in the early period is necessary, remains unclear...

To investigate the incidence and risk factors of hepatitis B virus (HBV) reactivation in HBV surface antigen (HBsAg)- / HBV core antibody (HBcAb)+ patients who underwent rituximab (RTX) therapy for rheumatoid arthritis (RA). From January 2000 through December 2017, a total of 134 RA patients with various HBV serostatuses who received RTX at Dalin Tzu Chi Hospital were screened. Finally, 50 HBsAg- /HBcAb+ patients were enrolled in this retrospective study. Baseline characteristics, comedications, and the occurrence of HBV reactivation were recorded...

An 88-year-old man was admitted for elevated liver enzyme levels. Nine years earlier, the patient had been diagnosed with diffuse large B-cell lymphoma (DLBCL) and undergone rituximab, cyclophosphamide, doxorubicin hydrochloride, oncovin, prednisone (R-CHOP) therapy. This patient previously had had a hepatitis B virus (HBV) infection before chemotherapy. After the chemotherapy, he was administered an LHRH agonist for prostate cancer. We diagnosed him with HBV reactivation because of positive serum HBV-DNA. HBV reactivation can occur a long time after chemotherapy, particularly if another treatment with immunity-altering drugs is added...

BACKGROUND: Hepatitis B virus (HBV) infection is a worldwide concern with a broad distribution. In immunosuppressed populations, such as solid organ and hematopoietic stem cell transplant (HSCT) recipients, it can reactivate leading to acute hepatic failure. Different risk factors are known for higher rates of reactivation, and entecavir, tenofovir, and lamivudine are often used for prophylaxis and treatment. However, data regarding the impact of antiviral drugs in neutrophil and platelet engraftment are still unknown and concerns the management of viral hepatitis post-HSCT...

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...
