Poola S, Kratzer M, Sewell K, Tillmann HL. Size Matters! Anti-HBs Titer and HBV Reactivation During Anti-TNF Therapy. Dig Dis Sci 2023; 68:4511-4520. [PMID: 37891440 DOI: 10.1007/s10620-023-08141-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/09/2023] [Accepted: 10/02/2023] [Indexed: 10/29/2023]
Abstract
BACKGROUND AND AIMS We and others have previously described that hepatitis B surface antibody (anti-HBs) seems to protect against clinically significant HBV reactivation in cohort studies of patients undergoing anti-tumor necrosis factor (TNF) therapy. However, there were too few cases of HBV reactivation within cohort studies to assess the role of anti-HBs titer on reactivation. The purpose of this study was to systematically review the correlation between anti-HBs titer and the degree of clinically relevant HBV reactivation in patients undergoing anti-TNF therapy. METHODS AND RESULTS We systemically reviewed all studies discussing anti-TNF therapy in patients with resolved HBV infection, defined as hepatitis surface antigen (HBsAg) negative and hepatitis B core antibody (anti-HBc) positive. We identified a total of 48 cases of reactivation from 5 cohort studies and 10 case reports or case series; 21 were anti-HBs negative, 7 were only reported as anti-HBs positive, 16 were anti-HBs positive with titer below 100, and 4 were anti-HBs positive with titer above 100. HBsAg sero-reversion was dominantly seen in patients with negative, low and/or declining anti-HBs titers. There was a significant trend toward less clinically relevant form of reactivation with increase in baseline anti-HBs titer (p = 0.022). CONCLUSION Anti-HBs titers greater than 100 iU/L protect against clinically relevant HBV reactivation, while patients with low anti-HBs titers or negative anti-HBs had more clinically relevant HBV reactivation and higher rates of HBsAg sero-reversion. This suggests the importance of baseline quantitative anti-HBs prior to starting anti-TNF therapy and consideration vaccination for boosting anti-HBs titers prior to and/or during therapy.

Abstract
Idiopathic nephrotic syndrome is the most common glomerular disease in children. Corticosteroids are the cornerstone of its treatment, and steroid response is the main prognostic factor. Most children respond to a cycle of oral steroids, and are defined as having steroid-sensitive nephrotic syndrome. Among the children who do not respond, defined as having steroid-resistant nephrotic syndrome, most respond to second-line immunosuppression, mainly with calcineurin inhibitors, and children in whom a response is not observed are described as multidrug resistant. The pathophysiology of nephrotic syndrome remains elusive. In cases of immune-mediated origin, dysregulation of immune cells and production of circulating factors that damage the glomerular filtration barrier have been described. Conversely, up to a third of cases of steroid-resistant nephrotic syndrome have a monogenic origin. Multidrug resistant nephrotic syndrome often leads to kidney failure and can cause relapse after kidney transplant. Although steroid-sensitive nephrotic syndrome does not affect renal function, most children with steroid-sensitive nephrotic syndrome have a relapsing course that requires repeated steroid cycles with significant side-effects. To minimise morbidity, some patients require steroid-sparing immunosuppressive agents, including levamisole, mycophenolate mofetil, calcineurin inhibitors, anti-CD20 monoclonal antibodies, and cyclophosphamide. Close monitoring and preventive measures are warranted at onset and during relapse to prevent acute complications (eg, hypovolaemia, acute kidney injury, infections, and thrombosis), whereas long-term management requires minimising treatment-related side-effects. A subset of patients have active disease into adulthood.

Incidence, risk factors, and clinical outcomes of HBV reactivation in non-liver solid organ transplant recipients with resolved HBV infection: A systematic review and meta-analysis. PLoS Med 2023; 20:e1004196. [PMID: 36920988 PMCID: PMC10058170 DOI: 10.1371/journal.pmed.1004196] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/19/2022] [Revised: 03/29/2023] [Accepted: 02/09/2023] [Indexed: 03/16/2023] Open
Abstract
BACKGROUND Current guidelines do not recommend routine antiviral prophylaxis to prevent hepatitis B virus (HBV) reactivation in non-liver solid organ transplant (SOT) recipients with resolved HBV infection, even in anti-hepatitis B surface antigen (anti-HBs)-negative recipients and those receiving intense immunosuppression. This systematic review and meta-analysis aimed to determine the incidence, risk factors, and clinical outcomes of HBV reactivation in non-liver SOT recipients. METHODS AND FINDINGS Three databases (PubMed, Embase, and Cochrane Library) were systematically searched up to December 31, 2022. Clinical studies reporting HBV reactivation in non-liver SOT recipients were included. Case reports, case series, and cohort studies with a sample size of less than 10 patients were excluded. Random-effects analysis was used for all meta-analyses. We included 2,913 non-liver SOT recipients with resolved HBV infection from 16 retrospective cohort studies in the analysis. The overall HBV reactivation rate was 2.5% (76/2,913; 95% confidence interval [95% CI 1.6%, 3.6%]; I2 = 55.0%). Higher rates of reactivation were observed in recipients with negative anti-HBs (34/421; 7.8%; 95% CI [5.2%, 10.9%]; I2 = 36.0%) by pooling 6 studies, experiencing acute rejection (13/266; 5.8%; 95% CI [2.3%, 14.5%]; I2 = 63.2%) by pooling 3 studies, receiving ABO blood type-incompatible transplantation (8/111; 7.0%; 95% CI [2.9%, 12.7%]; I2 = 0%) by pooling 3 studies, receiving rituximab (10/133; 7.3%; 95% CI [3.4%, 12.6%]; I2 = 0%) by pooling 3 studies, and receiving anti-thymocyte immunoglobulin (ATG, 25/504; 4.9%; 95% CI [2.5%, 8.1%]; I2 = 49.0%) by pooling 4 studies. Among recipients with post-transplant HBV reactivation, 11.0% (7/52; 95% CI [4.0%, 20.8%]; I2 = 0.3%) developed HBV-related hepatic failure, and 11.0% (7/52; 95% CI [4.0%, 20.8%]; I2 = 0.3%) had HBV-related death. Negative anti-HBs (crude odds ratio [OR] 5.05; 95% CI [2.83, 9.00]; p < 0.001; I2 = 0%), ABO blood type-incompatible transplantation (crude OR 2.62; 95% CI [1.05, 6.04]; p = 0.040; I2 = 0%), history of acute rejection (crude OR 2.37; 95% CI [1.13, 4.97]; p = 0.022; I2 = 0%), ATG use (crude OR 3.19; 95% CI [1.48, 6.87]; p = 0.003; I2 = 0%), and rituximab use (crude OR 3.16; 95% CI [1.24, 8.06]; p = 0.016; I2 = 0%) increased the risk of reactivation. Adjusted analyses reported similar results. Limitations include moderate heterogeneity in the meta-analyses and that most studies were conducted in kidney transplant recipients. CONCLUSIONS Non-liver SOT recipients with resolved HBV infection have a high risk of HBV-related hepatic failure and HBV-related death if HBV reactivation occurs. Potential risk factors for HBV reactivation include rituximab use, anti-thymocyte immunoglobulin use, anti-HBs negative status, acute rejection history, and ABO blood type-incompatible transplantation. Further research on monitoring and routine antiviral prophylaxis of non-liver SOT recipients at higher risk of HBV reactivation is required.

Patients treated with rituximab are poorly screened for hepatitis B infection: Data from a low-incidence country. Eur J Intern Med 2023; 108:68-73. [PMID: 36462966 DOI: 10.1016/j.ejim.2022.11.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/25/2022] [Revised: 11/14/2022] [Accepted: 11/16/2022] [Indexed: 12/05/2022]
Abstract
BACKGROUND & AIMS Patients with chronic or resolved hepatitis B are at risk of hepatitis B reactivation (HBVr) when treated with high-risk immunosuppressive therapy such as rituximab. Therefore, international guidelines recommend HBV screening prior to rituximab treatment and subsequent antiviral prophylaxis among patients with a (resolved) infection. In this study, we evaluated the adherence to those recommendations. METHODS This is a retrospective multicentre study including patients treated with rituximab between 2000-2021. Performance of correct screening was assessed, defined as the measurement of hepatitis B surface antigen (HBsAg) and hepatitis B core antibodies (anti-HBc). Next, initiation of antiviral prophylaxis and HBVr rate among patients with a chronic or resolved HBV infection was studied. RESULTS We enrolled 3,176 patients of whom 1,448 (46%) were screened correctly. Screening rates differed significantly between academic and non-academic hospitals; respectively 65% vs 32% (p<0.001). In addition, screening rates differed across specialties and improved throughout the years; from 32% before 2012 to 75% after 2020 among academic prescribers, versus 1% to 60% among non-academic prescribers (both p<0.001). Antiviral prophylaxis was initiated in 58% vs 36% of the patients with a chronic or resolved HBV infection. Seven patients experienced HBVr, including one fatal liver decompensation. CONCLUSIONS Many patients treated with rituximab were not correctly screened for HBV infection and antiviral prophylaxis was often not initiated. Although screening rates improved over time, rates remain suboptimal. With the increasing number of indications for rituximab and other immunosuppressive agents these findings could raise awareness among all medical specialties prescribing these agents.

Abstract
A 72-year-old woman presented to our hospital with elevation of serum transaminases. Her blood tests showed the hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg) negative. Rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) were given for the diffuse large B-cell lymphoma. She didn't receive anti- hepatitis B virus (HBV) drug for the isolated HBcAb positive. HBV reactivation confirmed based on the serum HBV DNA detectable until 19 months after stopping R-CHOP regimen. HBV DNA became undetectable after 4 weeks therapy with Tenofovir alafenamide fumarate (TAF). Serum transaminases went down to normal 3 months later after receiving TAF. HBV reactivation is a substantial risk for patients with isolated HBcAb positive receiving rituximab-containing chemotherapy without anti- HBV drug. Regular monitoring with a frequency of 1-3 months is the basis for timely diagnosis and treatment of HBV reactivation. Serum transaminases abnormalities may be the initial manifestation of HBV reactivation.

Abstract
Hepatitis B virus (HBV) can hide in the liver in the form of covalently closed circular DNA. When the body’s immunity changes, HBV reactivation (HBV-R) can occur. The risk of HBV-R is determined by the complex interaction among virological factors, medication factors and host factors. However, many patients do not know that they are infected with HBV, and doctors often do not invest enough time to systematically evaluate the patient’s HBV-R risk factors before immunosuppressive treatment. Therefore, HBV clinical screening should be vigorously promoted to achieve early detection and early prevention for patients with high risk of HBV-R. The mechanism, clinical features, risk factors, HBV-R under different disease etiologies, prevention and treatment of HBV-R were summarized to improve the in-depth understanding and awareness.

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
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. every 4-6 weeks during rituximab treatment, every 6-8 weeks in the first year post-treatment, and every 3-4 months in the second year post-treatment. MEASUREMENTS The efficacy of the surveillance protocol was examined by evaluating the rates of reactivation-related events. Feasibility was evaluated based on patient adherence. An economic analysis using a cost-minimization approach was conducted to compare the costs between the surveillance protocol and universal prophylaxis with entecavir 0.5 mg daily up to 1 year after cessation of rituximab. MAIN RESULTS A total of 66 patients provided analyzable data with a follow-up period of 966.6 months. No hepatitis flare or reactivation-related events were detected. The median adherence rate to the surveillance protocol was 90.5%. Cost savings of US$946.40 per patient over the entire surveillance period were achieved if the surveillance protocol was adopted and was most affected by changes in prophylaxis duration and the cost of antiviral prophylaxis. CONCLUSIONS The surveillance protocol is an effective, feasible and cost-saving strategy to manage HBV reactivation among lymphoma patients with resolved HBV infection receiving rituximab.

[PMID: 32994690 PMCID: PMC7504243 DOI: 10.3748/wjg.v26.i35.5314] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/23/2020] [Revised: 07/27/2020] [Accepted: 08/12/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND It is unclear whether immune escape-associated mutations in the major hydrophilic region of hepatitis B virus surface antigen (HBsAg) are associated with nucleoside/nucleotide analog resistance.
AIM To evaluate the association between immune escape-associated mutations and nucleoside/nucleotide analog resistance mutations.
METHODS In total, 19440 patients with chronic hepatitis B virus infection, who underwent resistance testing at the Fifth Medical Center of Chinese PLA General Hospital between July 2007 and December 2017, were enrolled. As determined by sequence analysis, 6982 patients harbored a virus with resistance mutations and 12458 harbored a virus lacking resistance mutations. Phenotypic analyses were performed to evaluate HBsAg production, replication capacity, and drug-induced viral inhibition of patient-derived drug-resistant mutants with or without the coexistence of sA159V.
RESULTS The rate of immune escape-associated mutation was significantly higher in 9 of the 39 analyzed mutation sites in patients with resistance mutations than in patients without resistance mutations. In particular, these mutations were sQ101H/K/R, sS114A/L/T, sT118A/K/M/R/S/V, sP120A/L/Q/S/T, sT/I126A/N/P/S, sM133I/L/T, sC137W/Y, sG145A/R, and sA159G/V. Among these, sA159V was detected in 1.95% (136/6982) of patients with resistance mutations and 1.08% (134/12,458) of patients lacking resistance mutations (P < 0.05). The coexistence of sA159V with lamivudine (LAM) and entecavir (ETV)-resistance mutations in the same viral genome was identified during follow-up in some patients with drug resistance. HBsAg production was significantly lower and the replication capacity was significantly higher, without a significant difference in LAM/ETV susceptibility, in sA159V-containing LAM/ETV-resistant mutants than in their sA159V-lacking counterparts.
CONCLUSION In summary, we observed a close link between the increase in certain immune escape-associated mutations and the development of resistance mutations. sA159V might increase the fitness of LAM/ETV-resistant mutants under environmental pressure in some cases.

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
INTRODUCTION Rituximab, an anti-B-cell biological therapy, has been investigated in several clinical trials on antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAVs). AREAS COVERED In this paper, the clinical trials and open-label studies on rituximab efficacy and safety in treating AAVs are reviewed. EXPERT OPINION Rituximab achieved high remission-induction and sustained-maintenance rates for patients with these severe diseases, thereby challenging the cornerstone treatment of corticosteroids and cyclophosphamide followed by azathioprine. Rituximab should be used as first-line therapy with corticosteroids to induce remission of severe AAVs, especially in situations in which cyclophosphamide may be problematic (relapse after cyclophosphamide, women of childbearing age, risk of malignancy). Cyclophosphamide indications are likely to be restricted in the future. Whenever possible, rituximab should be preferred to azathioprine to maintain remission. The current maintenance regimen has been extended to at least 18 months but its optimal duration remains unknown and recent data suggest the possibility to extend treatment to 4 years. Future challenges include defining the best dose regimen: at present, different schedules are used as alternatives to those recognized as standards by health authorities. In addition, it remains to identify which patients will benefit the most from long-term retreatment: potentially those with relapsing disease or anti-proteinase-3 ANCA-positivity.

Abstract
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. Data series of HBV seromarkers and HBV DNA levels before the patients receiving chemotherapy and/or hematopoietic stem cell transplantation (HSCT) and during follow-up duration were analyzed. RESULTS In total, 533 leukemia patients with resolved HBV infection were included. The incidences of HBVr were 5.7% (25/441) and 2.2% (2/92) in patients receiving HSCT and chemotherapy, respectively. In patients receiving HSCT, acute lymphoid leukemia had a significantly higher incidence of HBVr than acute myeloid leukemia (8.9% vs 3.9%, P < 0.05). The incidence varied almost zero to 40% due to the differences in the profiles of HBV antibodies. High anti-HBs (cut-off of 79.2 IU/L) or low anti-HBc levels (cut-off of 4.475, S/CO) at baseline were associated with a low risk of HBVr. Anti-HBe status did not affect the incidence of HBVr. However, the cut-offs were only predictive of HBVr in the patients who had negative anti-HBe. CONCLUSION The baseline profiles of HBV antibodies are predictive of the risk of HBVr in leukemia patients undergoing immunosuppression. However, seronegative anti-HBe is a prerequisite for using baseline anti-HBs and anti-HBc quantification to predict HBVr risk.

Abstract
INTRODUCTION The risk of HBV reactivation is important in lymphoma patients receiving immunosuppressive chemotherapy containing steroids or anti-CD20 antibodies. We aimed to establish the prevalence of HBV Ag and anti-HBc serologic positive results in patients with non-Hodgkin lymphoma (NHL) and chronic lymphocytic leukemia (CLL) in Poland before anti-CD20 therapy initiation; to assess the frequency of insufficient HBV screening; and to assess the association between inadequate HBV screening and diagnosis according to the WHO classification and age or gender. MATERIAL AND METHODS We retrospectively collected data from 805 patients with non-Hodgkin lymphoma and chronic lymphocytic leukemia treated in 2016-2018. RESULTS We found a positive result of HBsAg in 13 (1.16%), and a negative result in 633 (78.64%) patients. The test was not done in 159 (19.75%) patients. In the HBsAg negative subgroup of 633 patients, we found that the anti-HBc was positive in 52 (8.22%), negative in 303 (47.87%) and not done in 278 patients. In 136 out of 805 (16.9%) patients diagnostics tests were not performed before therapy initiation. We found that age is significantly associated (p = 0.0002) with the lack of HBV infection screening, and in CLL this risk is significantly (p = 0.024) higher (by 49%) compared with other WHO diagnosis subgroups. CONCLUSIONS In Polish lymphoma patients the incidence of positive HBsAg and/or anti-HBc results is consistent with the prevalence in the United States or Australia. The adherence to appropriate HBV screening guidelines in Polish centers is not sufficient. We should intensify educational strategies in the global oncohematologic medical community.

Abstract
The association between B-cell non-Hodgkin lymphoma (NHL) and hepatitis B virus (HBV) is well demonstrated by epidemiological studies. Most studies concerning this association have been conducted in endemic areas. Thus, little is known concerning the clinical characteristics of HBV-related lymphomas in non-endemic areas. Here, we report the characteristics and outcomes of 39 patients with active HBV infection and B-cell NHL collected retrospectively in France and Italy. We also compared their characteristics with those of HCV-positive patients with NHL. The gender ratio (M/F) was 3.3 and the median age at NHL diagnosis, 59 years. The pathological distribution was 24 (62%) diffuse large B-cell lymphomas (DLBCLs) and 15 (38%) other lymphomas subtypes: marginal zone lymphoma (n = 6), follicular lymphoma (n = 3), mantle cell lymphoma (n = 2), Burkitt's lymphoma (n = 1), and not otherwise specified low-grade B-NHL (n = 3). Treatment included antiviral therapy for 35 patients (90%). Twenty-two (92%) DLBCL patients received an R-CHOP or R-CHOP-like regimen, leading to complete remission for 18 (75%).At one year, 21 DLBCL patients (88%) were alive, and 13 other B-cell lymphoma patients (87%) were alive. This European study underscores the predominance of DLBCL among patients with active HBV infection and their similar outcomes to non-HBV infected patients with DLBCL when treated with R-CHOP and antivirals.

Abstract
The genetic diversity of orthohepadnaviruses is not yet fully understood. This study was conducted to investigate the role of structural variations (SVs) in their diversity. Genetic sequences of orthohepadnaviruses were retrieved from databases. The positions of sequence gaps were investigated, since they were found to be related to SVs, and they were further used to search for SVs. Then, a combination of pair-wise and multiple alignment analyses was performed to analyze the genomic structure. Unique patterns of SVs were observed; genetic sequences at certain genomic positions could be separated into multiple patterns, such as no SV, SV pattern 1, SV pattern 2, and SV pattern 3, which were observed as polymorphic changes. We provisionally referred to these genetic changes as SV polymorphisms. Our data showed that higher frequency of sequence gaps and lower genetic identity were observed in the pre-S1-S2 region of various types of HBVs. Detailed examination of the genetic structure in the pre-S region by a combination of pair-wise and multiple alignment analyses showed that the genetic diversity of orthohepadnaviruses in the pre-S1 region could have been also induced by SV polymorphisms. Our data showed that novel genetic rearrangements provisionally termed SV polymorphisms were observed in various orthohepadnaviruses.

Abstract
Hepatitis B virus (HBV) is one of the main causes of chronic liver diseases and hepatocellular carcinoma. After infection the majority of HBV-infected patients achieve immune control leading to HBV-DNA stabilization at a low level. The risk of HBV reactivation rises significantly when HBV-infected patients receive immunosuppressive treatments. Presented recommendations provide guidelines for management of patients scheduled or undergoing therapies, which through their immunomodulatory activity contribute to the impairment of antiviral immunity, including chemotherapy, immunosuppressive treatment or biological therapy.

Abstract
Objective To determine the clinical features and survival difference of HBV related and Non-HBV related diffuse large B-cell lymphoma (DLBCL) and to evaluate the occurrence of HBV reactivation in DLBCL patients and related risk factors for HBV reactivation after R-CHOP therapy. Methods A total of 246 patients diagnosed with CD20+ DLBCL were enrolled from June 2010 to June 2015. The medical records and survival data were analysed. Multivariate logistic regression analysis was used to identify predictors of HBV reactivation. Survival curves were performed by the Kaplan-Meier method. Results Among patients enrolled, 80 patients were HBsAg sero-positive and 166 patients were HBsAg sero-negative. Findings showed that HBsAg sero-negative patients were significantly older than that of patients with HBsAg sero-positive (P < 0.001). Proportion of B symptom positive patients in HBsAg sero-positive were higher (p = 0.002). Higher LDH level (P = 0.019) and late Ann Arbor stage (P = 0.010) were more often observed in patients with HBsAg sero-positive. The rate of complete response, partial response, stable disease and progress disease in HBsAg sero-negative group were 63.9, 16.9, 1.1 and 18.1%, respective, which is significantly higher than that in HBsAg sero-positive group (36.2, 18.8, 1.2 and 43.8%). Kaplan-Meier analysis showed that DLBCL patients with HBsAg sero-negative had better prognosis. In total, 17 patients showed HBV reactivation among 166 patients (10.2%) with HBsAg sero-negative after R-CHOP treatment, while a significant higher HBV reactivation 18.75% (9/48) in HBsAb negative group were observed, with 8.25% (8/97) patients in HBsAb level 10-100 U/mL group, and 0% patients in HBsAb level higher than 100 U/mL group. Multivariable analysis showed that serum HBsAb and serum HBcAb were independent risk factors for HBV reactivation in DLBCL patients. Conclusion Our data revealed that characteristics and prognosis were significantly different between HBV related DLBCL than non-HBV related DLBCL patients. DLBCL patients with resolved hepatitis B are at a higher risk of developing HBV reactivation after R-CHOP chemotherapy compared with HBsAg-negative/HBcAb negative patients.

Abstract
Hepatitis B virus (HBV) reactivation is a common complication of immunosuppressive treatment in high prevalence countries. Biological disease-modifying antirheumatic drugs (bDMARDs) cause this adverse event more often than conventional immunosuppressants. The incidence of HBV reactivation during treatment for rheumatic diseases in Germany is unclear. Furthermore, it remains open how to treat and monitor patients at risk during immunosuppressive therapy with bDMARDs. We examined 2054 patients from a German tertiary rheumatology center in order to analyze the prevalence of HBc-antibody-positivity and the incidence of HBV reactivation in German rheumatology patients treated with immunosuppressants. Of 1317 patients treated with bDMARDs and 737 conventional synthetic DMARD (csDMARDs) patients between 2008 and 2017, 86 had a history of HBV infection (anti-HBc positive). Only two patients were suffering from chronic infection (HBsAg positive). Three patients were treated pre-emptively with entecavir, and eight patients after HBV DNA reappearance. No liver failure occurred due to HBV reactivation. Compared to anti-HBc-positive patients without reactivation, the reactivation group included more patients exposed to three or more classes of bDMARDs (p = 0.017). The median HBs antibody titer was significantly lower in the reactivation group (15.0 IU/l vs. 293.5 IU/l; p = 0.001). This study shows that bDMARDs and csDMARDs can safely be administered to patients with a history of HBV, provided they are closely monitored. Low titers of anti-HBs antibodies and a history of ≥ 3 classes of immunosuppressants increase the risk of HBV reactivation. These data highlight major differences to high prevalence regions.

Three-year Follow-up on the Safety and Effectiveness of Rituximab Plus Chemotherapy as First-Line Treatment of Diffuse Large B-Cell Lymphoma and Follicular Lymphoma in Real-World Clinical Settings in China: A Prospective, Multicenter, Noninterventional Study. Chin Med J (Engl) 2018; 131:1767-1775.

Abstract
BACKGROUND Prospective real-life data on the safety and effectiveness of rituximab in Chinese patients with diffuse large B-cell lymphoma (DLBCL) or follicular lymphoma (FL) are limited. This real-world study aimed to evaluate long-term safety and effectiveness outcomes of rituximab plus chemotherapy (R-chemo) as first-line treatment in Chinese patients with DLBCL or FL. Hepatitis B virus (HBV) reactivation management was also investigated. METHODS A prospective, multicenter, single-arm, noninterventional study of previously untreated CD20-positive DLBCL or FL patients receiving first-line R-chemo treatment at 24 centers in China was conducted between January 17, 2011 and October 31, 2016. Enrolled patients underwent safety and effectiveness assessments after the last rituximab dose and were followed up for 3 years. Effectiveness endpoints included progression-free survival (PFS) and overall survival (OS). Safety endpoints were adverse events (AEs), serious AEs, drug-related AEs, and AEs of special interest. We also reported data on the incidence of HBV reactivation. RESULTS In total, 283 previously untreated CD20-positive DLBCL and 31 FL patients from 24 centers were enrolled. Three-year PFS was 59% (95% confidence interval [CI]: 50-67%) for DLBCL patients and 46% (95% CI: 20-69%) for FL patients. For DLBCL patients, multivariate analyses showed that PFS was not associated with international prognostic index, tumor maximum diameter, HBV infection status, or number of rituximab treatment cycles, and OS was only associated with age >60 years (P < 0.05). R-chemo was well tolerated. The incidence of HBV reactivation in hepatitis B surface antigen (HBsAg)-positive and HBsAg-negative/hepatitis B core antibody-positive patients was 13% (3/24) and 4% (3/69), respectively. CONCLUSIONS R-chemo is effective and safe in real-world clinical practice as first-line treatment for DLBCL and FL in China, and that HBV reactivation during R-chemo is manageable with preventive measures and treatment.

Abstract
Liver transplantation (LT) is one of the most effective treatments for end-stage liver disease caused by related risk factors when liver resection is contraindicated. Additionally, despite the decrease in the prevalence of hepatitis B virus (HBV) over the past two decades, the absolute number of HBsAg-positive people has increased, leading to an increase in HBV-related liver cirrhosis and hepatocellular carcinoma. Consequently, a large demand exists for LT. While the wait time for patients on the donor list is, to some degree, shorter due to the development of living donor liver transplantation (LDLT), there is still a shortage of liver grafts. Furthermore, recipients often suffer from emergent conditions, such as liver dysfunction or even hepatic encephalopathy, which can lead to a limited choice in grafts. To expand the pool of available liver grafts, one option is the use of organs that were previously considered “unusable” by many, which are often labeled “marginal” organs. Many previous studies have reported on the possibilities of using marginal grafts in orthotopic LT; however, there is still a lack of discussion on this topic, especially regarding the feasibility of using marginal grafts in LDLT. Therefore, the present review aimed to summarize the feasibility of using marginal liver grafts for LDLT and discuss the possibility of expanding the application of these grafts.

Abstract
The spectrum of therapeutic options for immunotherapy of multiple sclerosis is continuously broadening. After the approval of cladribine and ocrelizumab in Europe, two new drugs are now available with ocrelizumab being the first approved option for treatment of primary progressive multiple sclerosis; however, the increased use of highly effective therapies is accompanied by a rise in severe side effects. During recent months, special attention was paid to the new progressive multifocal leukoencephalopathy (PML) risk assessment in natalizumab-treated patients, cardiac side effects of fingolimod, cases of idiopathic thrombocytopenic purpura and listeria meningitis associated with alemtuzumab and cases of daclizumab-treated patients with liver failure or encephalitis. These case reports highlight the importance of careful monitoring of all patients treated with immunomodulatory therapies.
