Background: There is currently no data regarding the efficacy of prophylactic telbivudine in hepatitis B patients undergoing chemotherapy. This study aims to describe the results of preemptive telbivudine and lamivudine to prevent chemotherapy-related HBV reactivation.Methods: The medical records of all patients with HBsAg positive or HBs-Ag negative, anti-HBc positive, who were referred to the hepatology clinic between May 2014 and December 2016, were retrospectively reviewed. As this is a descriptive study, no statistical analysis was done.Results: A total of 52 patients with prophylactic telbivudine or lamivudine therapy were included, with 26 patients in each group. Rituximab-based treatment was given in nine and five patients in the telbivudine and lamivudine group, respectively. The number of patients who completed antiviral treatment up to six months after chemotherapy was 17 patients in each group. There was less incidence of HBV reactivation in the telbivudine group (2 of 17 patients, 11.8%) than in the lamivudine group (7 of 17 patients, 41.2%). Delayed reactivation was noticed in 1 of 2 patients in the telbivudine group and 3 of 7 patients in the lamivudine group. The median log10[HBV DNA] at reactivation was 4.52 (1.70 – 8.35) IU/mL. Severe hepatitis was observed in two patients in the lamivudine group and one patient in the telbivudine group. Of 34 patients who completed antiviral treatment, two patients died due to primary cancer. No interruption of chemotherapy or mortality due to hepatitis was noticed in both groups.Conclusions: Preemptive telbivudine or lamivudine in HBsAg positive or HBsAg negative, anti-HBc positive patients seems to be a good treatment option.

Abstract Abstract 2641 INTRODUCTION: Since the introduction of the anti-CD20 monoclonal antibody rituximab, the outcomes of B-cell non-Hodgkin lymphoma (B-NHL) have improved markedly. However, fulminant hepatitis due to reactivation of hepatitis B virus (HBV) infection has emerged as a serious problem. Recently, rituximab plus corticosteroid containing chemotherapy (R-chemo) has been identified as a risk factor for HBV reactivation in hepatitis B surface antigen (HBsAg)-negative B-NHL patients. Currently, there is no standard management to prevent HBV reactivation in HBV-resolved patients without HBsAg, but with antibodies against hepatitis B core antigen (anti-HBc) and/or HBsAg (anti-HBs). PATIENTS AND METHODS: We conducted a multicenter prospective observational study to estimate the incidence of HBV reactivation by serial monthly monitoring of HBV DNA in HBV-resolved patients with B-NHL during and just after R-chemo, and to establish preemptive antiviral therapy guided by this monitoring. The major eligibility criteria included previously untreated CD20-positive B-NHL with prior HBV-resolved infection, and planned treatment with 6 to 8 cycles of R-chemo defined by protocol. The baseline HBV status was evaluated on enrollment at each institute, comprising HBsAg, anti-HBc, and anti-HBs serology. Patients were excluded if they were seropositive for hepatitis C virus or human immunodeficiency virus. Plasma HBV DNA levels were measured independently at a central laboratory, using an automated real-time TaqMan polymerase chain reaction assay after enrollment. The primary end point was the incidence of HBV reactivation defined as HBV DNA levels of 1.8 log copies per mL or more. If HBV DNA levels of less than 1.8 log copies per mL were confirmed at baseline, the serial monitoring of HBV DNA (without prophylaxis of antiviral drugs) was performed with assessments every 4 weeks after enrollment for 1.5 years. Prompt antiviral treatment with an anti-HBV nucleoside analogue (entecavir, 0.5 mg per day) was highly recommended in patients with confirmed HBV reactivation. An ancillary study was conducted to identify risk factors for HBV reactivation using the preserved specimens. The protocol was approved by the Institutional Review Board of each participating institution. All patients gave written informed consent. The planned interim analysis was performed after the enrollment of 200 patients, using data available up to June 30, 2011. RESULTS: Between Sept. 2008 and Sept. 2010, a total of 187 patients (50.8% male) with a median age of 63 years (range, 26 to 79) from 45 institutes were analyzed. Histologic subtypes of B-NHL were diffuse large B-cell lymphoma (n=121, 64.7%), follicular lymphoma (n=57, 30.5%), MALT lymphoma (n=5, 2.7%) and other types (n=4, 2.0%). The number (%) of patients positive for both anti-HBc and anti-HBs was 132 (70.6%), 35 (18.7%) were positive for anti-HBc but negative for anti-HBs, and 19 (10.2%) were negative for anti-HBc but positive for anti-HBs. One patient was positive for anti-HBc but lacked anti-HBs measurement. 168 (89.8%) patients received 6 to 8 cycles of R-CHOP (n=151) or other R-chemo (n=17). With a median follow-up of 549 days (range, 35 to 939), HBV reactivation was observed in 16 out of 187 analyzed patients. The incidence of HBV reactivation at 1 year was 7.7% (95% confidence interval [CI], 4.7 to 12.7). HBV reactivation was diagnosed at a median time of 158 days (range, 33 to 490) after enrollment. No hepatitis due to HBV reactivation was observed in patients who received antiviral treatment when HBV DNA levels were 1.8 to 3.1 log copies per mL. Multivariate analysis of the ancillary study showed that an anti-HBs baseline titer less than 10 mIU per mL was an independent risk factor for HBV reactivation, compared to a titer of 100 mIU per mL or more (adjusted hazard ratio, 5.3; 95% CI, 1.3 to 21.8; p=0.02). HBV mutations of precore (G1896A) or basal core promoter (A1762T/G1764A) that enhanced HBV replication were identified in 4 patients, two of whom had both mutations. Our strategy could inhibit such highly replicative clones and prevent hepatitis. CONCLUSIONS: Monthly monitoring of HBV DNA is highly effective for preventing hepatitis due to HBV reactivation in HBV-resolved B-NHL patients treated with R-chemo.

Abstract Background: Reactivation of hepatitis B virus (HBV) is a well-recognized complication in patients with chronic HBV infection undergoing cytotoxic or immunosuppressive therapy. Currently, BCR-ABL1 tyrosine kinase inhibitors (TKIs) have been a standard of first-line treatment for chronic myeloid leukemia (CML) about last two decades. As there have been several case reports of HBV reactivation in CML patients treated with TKIs, the test for hepatitis B infection before initiating TKIs is recommended. Therefore, this study aimed to evaluate the risk of HBV reactivation in a large cohort of CML patients on TKIs treatment. Methods: We retrospectively reviewed the medical records of 1817 patients, who were diagnosed with CML and had available HBV serology between 2001 and 2017 from St. Mary's Hospital, Seoul, Korea. Results: Among 1817 patients, 76 patients (4.2%) were HBs-antigen (HBs-Ag) positive and 1741 (95.2%) were HBs-Ag negative. 302 patients (17.3%) of 1741 HBs-Ag negative patients were HBc-antibody positive indicating past infection of HBV. After exclusion of 7 patients who did not receive TKIs treatment, 69 patients were analyzed for HBV reactivation. The median age at diagnosis of CML was 42 (range 21-73) years and 44 (64%) were males. Median duration of follow-up from the recognition of HBs-Ag was 66.7 months (range, 2.4 - 192.7 months). Of 69 patients, a patient had been on antiviral therapy for chronic HBV infection before the diagnosis of CML. Eighteen patients (26% of 68) received antiviral prophylaxis prior to or concomitantly with the initiation of TKIs. Additional 4 patients were simultaneously initiated antiviral treatment with TKIs due to the evidence of active HBV infection such as the high titer of HBV DNA or elevated level of Alanine aminotransferase. Among 46 patients who did not receive antiviral prophylaxis, 12 patients (26%; 95% CI, 12-36%) eventually required antiviral treatment due to the development of active HBV hepatitis while on TKI therapy. HBV reactivation according to each TKI treatment was developed in 7 patients with imatinib, 2 patients in dasatinib, 1 patient in nilotinib, and 1 patient in radotinib therapy. One patient developed HBV reactivation permanently discontinued TKI therapy. Median time to HBV reactivation from CML diagnosis was 22.1 (range, 6.3-124.6 months) months. Median duration of antiviral therapy of 35 patients who received antiviral therapy was 38.2 months (95% CI, 25.7 ~ 50.7 months). 9 patients were off antiviral therapy at the last follow-up, 5 patients from prophylaxis group and 4 patients from treatment group. There was no difference in the duration of antiviral treatment between prophylactic and treatment groups. The initial choice of antiviral therapy as prophylaxis or treatment were entecavir for 14 (41% of 34), lamivudine for 8 (24%), tenofovir for 8 (24%), telbivudine for 3 (9%), and adefovir for 1 (3%). Conclusion: We evaluated HBV reactivation in a large cohort of HBs-Ag positive patients with CML from a single center, who received TKIs treatment. The reactivation rate of HBV was high at 26% without antiviral prophylaxis, which strongly support the routine screening of HBV serology prior to initiation of TKI therapy to identify HBs-Ag positive patients and the close monitoring of hepatic functions and HBV serology during TKI therapy. Given the high incidence of HBV reactivation with TKI treatment, concomitant antiviral prophylaxis with TKIs should be considered in HBs-Ag positive patients receiving TKI treatment. Figure. Figure.

Background:In the recent decades, biological disease-modifying antirheumatic drugs (bDMARDs) have significantly improved management and quality of life in patients with rheumatoid arthritis (RA) and spondyloarthritis (SpA).However, bDMARDs have also a strong influence on the immune system, leading to a risk of serious infection. Reactivation of hepatitis B (HBV) and C (HCV) virus is one of the most redoubtable complications of these immunosuppressive agents.Objectives:The aims of this study were to determine the screening rate for hepatitis B and C before starting a biological treatment and to examine the prevalence of their markers in patients with RA or SpA.Methods:Our study evaluated all patients included in the Tunisian registry BINAR (Biologic National Registry) since 2018 who had RA (ACR/EULAR 2010) or SpA (ASAS criteria) aged with more than eighteen years old and receiving their first bDMARDs during the two past years.The following information were retrieved from the registry: demographic data on the patients, disease parameters, medication, HBV surface antigen (HBs Ag), antibody to HBs Ag (Anti HBs), antibody to HBV core antigen (Anti HBc), HBV-DNA, antibody to HCV (anti HCV) status and liver function tests (AST: aspartate aminotransferase; ALT:alanine aminotransferase).Results:A total of 298 patients was included, 111 men and 178 women, with a mean age of 49.2 ± 14.1 years old [18-79]. Among them, 58.7% were diagnosed with RA and 41.3% were diagnosed with SpA. The mean disease duration was 6.7±3.5 years [1-12] in patients with RA and 6.5±3 [1-12] in patients with SpA. The mean Disease Activity Score (DAS28) and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) were respectively of 4.9±1.5 [1-8] and 4.1±1.8 [0-9].Therapeutically, 167 patients (56%) were on Prednisone at a mean daily posology of 8.2±5.4 mg [4-60] and 70.3% on conventional synthetic disease modifying antirheumatic drug (csDMARD) in association with bDMARDs. It was about Tumor Necrosis Factor alpha antibodies (anti TNF a) in 87.9% of cases, Tocilizumab in 10.4% of cases and Rituximab in 5% of cases.A screening of HBV was performed in 286 patients (96%). Ag HBs was positive in two cases (0.7%), and anti-HBc was positive in 16 cases (6.4%) which indicate a prior HBV infection. Fifteen patients (6%) were immunized with positive anti HBs. HBV-DNA was measured in 177 cases (66.8%) and was positive in 15 patients (6%).HCV infection was searched in 282 patients (94.6%) and anti-HCV was negative in all cases.AST and ALT mean rates were respectively of 18.3 [2-108] and 17.9 UI/l [2-74]. A perturbation of these liver function tests was observed in 13 patients (4.4%).Conclusion:Screening for hepatitis B and C were performed respectively in 96% and 94% of our Tunisian patients before receiving any bDMARDs. This should be systematic to avoid HBV reactivation which can lead to fulminant hepatic failure with a severe prognosis.Disclosure of Interests:None declared

Abstract Background In co-infected patients with hepatitis B (HBV) and hepatitis C (HCV), the treatment of HCV with direct-acting antiviral agents (DAA) can cause HBV reactivation. However, there are no clear guidelines on the timing of treatment initiation, especially in the absence of clinical signs of flare. Aims Here we discuss the case of a 34-year-old female with HBV and HCV genotype 3 who had HBV reactivation following HCV treatment, but did not require nucleos(t)ide therapy. Methods She initially presented with chronic inactive hepatitis B and chronic hepatitis C with HBV DNA level of 67.5 IU/mL and HCV RNA level of 3.33 x 106 IU/mL. She completed a 12 week course of sofosbuvir and velpatasvir for HCV and achieved sustained virologic remission, but subsequently developed reactivation of her HBV with HBV DNA peaking at 3.41 x 104 IU/mL twelve weeks post-treatment. She did not develop any signs of hepatitis and a decision was made to monitor her clinically. Results Two years later, she spontaneously went into remission with her HBV DNA levels being <10 IU/mL. Conclusions The significance of this case is to illustrate HBV reactivation following treatment of HCV with DAAs may not necessitate immediate treatment, especially if there are no signs of flare. There have been similar reported cases, but larger prospective studies are required to determine the appropriate clinical context where monitoring may be acceptable instead of immediate treatment.

A 47-year-old man diagnosed with Crohn’s disease was treated with infliximab. He tested negative for hepatitis B surface antigen (HBsAg) and hepatitis B surface antibody (anti-HBs) but positive for anti-HB core antibody (anti-HBc). He tested positive for hepatitis B virus (HBV-) DNA 3 months after treatment and was administered entecavir. HBV-DNA test showed negative results 1 month later. ALT was persistently within the normal range, and HBV-DNA was persistently negative thereafter despite the continuation of infliximab every 8 weeks. In our hospital, 14 patients with inflammatory bowel disease, who tested negative for HBsAg, were treated with infliximab; 2 of them tested positive for anti-HBs and/or anti-HBc, and HBV reactivation was observed in 1 patient (the present patient). The present case and these findings highlight that careful follow-up is needed in patients with inflammatory bowel disease treated with infliximab who test positive for anti-HBc and/or anti-HBs.

Abstract INTRODUCTION Chemotherapy-induced hepatitis B virus (HBV) reactivation is a well-recognized complication and is a potentially life-threatening condition in cancer patients with chronic HBV (hepatitis B surface antigen [HBsAg]-positive). Rituximab has been associated with an increase in HBV reactivation in chronic HBV patients (45%) and even in patients with resolved infection (HBsAg negative and hepatitis B core antibody [anti-HBc]-positive (22%); however, the reported frequency varies among different studies. Current guidelines for management of chronic HBV recommend routine antiviral HBV prophylaxis with lymphoma before starting chemotherapy. In contrast, there is little evidence-based consensus regarding patients with resolved HBV infection. Aim: To analyze the incidence of HBV reactivation and the role of antiviral HBV prophylaxis in lymphoma patients with chronic HBV or resolved HBV treated with chemotherapy, immunotherapy or immunochemotherapy managed according to our institutional HBV guidelines. Secondary endpoints were to analyze the incidence of HBV in this population and HBV guidelines adherence. PATIENTS AND METHODS Lymphoma patients with chronic HBV or resolved HBV in a single center. HBV viral status definitions: Active Chronic HBV infection: HBsAg positive, anti-HBc positive and HBV DNA >2000 IU/mL; Inactive Carriers: HBsAg positive, Anti-HBc positive, HBV DNA undetectable or <2000 IU/mL with normal transaminases; Resolved HBV: HBsAg negative, anti-HBc positive, HBV DNA undetectable. HBV reactivation was defined as increased serum HBV DNA (≥1 log10), regardless of liver biochemistry or HBsAg status. Institutional HBV guidelines: serum samples were collected at baseline for HBsAg and anti-HBc testing in all lymphoma patients. Patients were evaluated by a hepatologist if any of them fulfilled HBV viral status definition. Baseline at screening and monitoring every 3 months during therapy and up to 24 months after completing therapy (assessment of liver biochemistry, serum HBV DNA, HBsAg and anti-HBs levels). Specific prophylaxis strategies according to HBV status: Group A (Active chronic HBV): treatment for HBV; Group B (Inactive carriers): antiviral HBV prophylaxis; Group C (Resolved HBV): antiviral HBV prophylaxis if rituximab containing-therapy or follow-up only if rituximab-free therapy. HBV antiviral prophylaxis was started before therapy and finished 12 months after completing therapy. RESULTS From January 2012 to January 2015, 227 lymphoma patients received chemotherapy or immunochemotherapy. 142 (63%) patients received rituximab-containing therapy. 43 (19%) patients were anti-HBc positive. Group A: 2 (1%) patients; Group B: 2 (1%) patients; Group C: 39 (17%) patients. 14 (6%) patients have coinfection with hepatitis C virus and 12 (5%) patients co-infection with human immunodeficiency virus (HIV). Adherence to HBV guidelines was 90%. Patients in Group A (n=2) and B (n=2) received antiviral treatment/prophylaxis before starting therapy. In the Group C, 16 (41%) patients underwent only follow-up and 23 (59%) patients received HBV antiviral prophylaxis (lamivudine in 4, entecavir in 8 and tenofovir in 11). Median duration of HBV prophylaxis was 18 months (95% CI: 16-19 months). After a median follow-up of 21 months, 2 patients developed HBV reactivation during lymphoma treatment: 1 from group B (reactivation rate of 50%) and 1 from group C (reactivation rate of 3%). Both patients had received rituximab-containing treatment and both developed HBV reactivation (without hepatitis flare) within the first 6 months after finishing antiviral HBV prophylaxis (delayed HBV reactivation). Outcome was favorable in both patients. Characteristics of HBV reactivation patients are shown in table I. Cumulative incidence of HBV reactivation at 12 and 24 months were 0% and 8%, respectively. CONCLUSION Our strategy of close monitoring patients with chronic HBV or resolved HBV that receive chemotherapy and adding antiviral HBV prophylaxis only in selected patients clearly decrease HBV reactivation. Nevertheless, this strategy may not fully protect patients from late HBV reactivations. Larger validation studies are needed to confirm our data and to establish the best cost-effective strategy in this lymphoma population, especially in the new era of inmunomodulatory drugs of their real involvement in HBV reactivation is unknown.

Hepatitis B Virus (HBV) can be transmitted vertically from mother to her baby. Mothers with HBsAg and HBeAg positives have more risk of transmitting HBV to her baby rather than HBsAg positives only. The aim of this study is to determine the proportion of maternal patient with HBsAg and HBeAg positives and their HBsAg positives babies with immunoprophylaxis of HBV immunization. This study was performed by analytical observation using medical records in 2013-2014 at Obstetric and Gyn ecology Department, Dr. Soetomo Hospital. The samples were all maternal patients (3796) during that period and also their babies from HBsAg positives mothers. Unfortunately, several original medical records were not available. Thirty two (0,85%) out of 3781 maternal patients were found to be HBsAg positives, and three (9,37%) of 32 patients with HBsAg positives were HBeAg positives. From 32 mothers who were positive HBsAg, 22 complete medical records of their babies were found and all of them (100%) had been given Hepatitis B Immunoglobulin (HBIG) and hepatitis B vaccine less than twelve hours after birth. In three cases of the babies from HBeAg positives mothers which had been given prophylaxis properly, two cases each of which was with caesarean and spontaneous delivery were HBsAg negatives. Interestingly, the other one which born with spontaneous delivery was found to be HBsAg positives. Further study in this HBsAg positives baby, especially in analyzing its HBV DNA is needed. The epidemiology of hepatitis B in maternal patients, especially that with complete and neat data needs further research.

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.

ObjectiveThe cost-effectiveness of antiviral treatment in adult immune-tolerant (IT) phase chronic hepatitis B (CHB) patients is uncertain.DesignWe designed a Markov model to compare expected costs and quality-adjusted life-years (QALYs) of starting antiviral treatment at IT-phase (‘treat-IT’) vs delaying the therapy until active hepatitis phase (‘untreat-IT’) in CHB patients over a 20-year horizon. A cohort of 10 000 non-cirrhotic 35-year-old patients in IT-phase CHB (hepatitis B e antigen-positive, mean serum hepatitis B virus (HBV) DNA levels 7.6 log10 IU/mL, and normal alanine aminotransferase levels) was simulated. Input parameters were obtained from previous studies at Asan Medical Center, Korea. The incremental cost-effectiveness ratio (ICER) between the treat-IT and untreat-IT strategies was calculated.ResultsFrom a healthcare system perspective, the treat-IT strategy with entecavir or tenofovir had an ICER of US$16 516/QALY, with an annual hepatocellular carcinoma (HCC) incidence of 0.73% in the untreat-IT group. With the annual HCC risk ≥0.54%, the treat-IT strategy was cost-effective at a willingness-to-pay threshold of US$20 000/QALY. From a societal perspective considering productivity loss by premature death, the treat-IT strategy was extremely cost-effective, and was dominant (ICER <0) if the HCC risk was ≥0.43%, suggesting that the treat-IT strategy incurs less costs than the untreat-IT strategy. The most influential parameters on cost-effectiveness of the treat-IT strategy were those related with HCC risk (HBV DNA levels, platelet counts and age) and drug cost.ConclusionStarting antiviral therapy in IT phase is cost-effective compared with delaying the treatment until the active hepatitis phase in CHB patients, especially with increasing HCC risk, decreasing drug costs and consideration of productivity loss.

Abstract Background The prophylaxis for hepatitis B virus (HBV) reactivation assumes that hepatic injury after reactivation is often rapidly progressive and can evoke fulminant hepatitis. The incidence and prognosis of reactivation in patients with rheumatoid arthritis (RA) may be different from those receiving organ transplantation and cancer chemotherapy. This study aimed to investigate the incidence, risk factors, and clinical course of HBV reactivation and develop a scoring system for risk stratification in RA patients with resolved infection. Methods HBV DNA was measured using real-time polymerase chain reaction, and patient data were collected for 4 years in RA patients with resolved HBV infection who were treated with steroids or synthetic or biologic immunosuppressive drugs. Results Among 1127 patients, HBV DNA was detected in 57 patients (1.65/100 person-years); none of the reactivated patients exhibited worsening of hepatic function. Multivariate logistical analysis revealed that age > 70 years and HB core antibody (HBcAb) positivity alone were independent risk factors for HBV reactivation. HBV DNA ≥ 2.1 log copies/mL was observed in 15 patients (0.43/100 person-years); seven patients were treated with nucleic acid analogs (NAAs), whereas the remaining eight were observed without treatment. Among reactivated cases, 15 cases changed to HBV DNA-negative status spontaneously, whereas 24 cases remained HBV DNA positive < 2.1 log copies/mL during the observation period. We designed the following scoring system: HBV reactivation risk score = 1 × (age > 70 years) + 2 × (HBcAb positivity alone) + 1 × (treatment other than methotrexate monotherapy). This revealed that patients with the highest score had an odds ratio of 13.01 for HBV reactivation, compared to those with the lowest score. Conclusions Rapid progression and poor outcomes after HBV reactivation were not frequent in RA patients with resolved infection. Our new risk scoring system might be useful for screening and optimization of prophylactic treatment by distinguishing patients with significantly lower reactivation risk.
