BACKGROUND:Hepatitis B virus (HBV) reactivation is a serious complication in patients with cancers and HBV infection undergoing immunosuppressant treatment or chemotherapy. However, the safety of anti-programmed cell death (PD) -1 and anti-programmed cell death-ligand 1 (PD-L1) therapy in these patients is unknown because they were excluded from clinical trials of immunotherapy. METHODS:This retrospective cohort study involved consecutive hepatitis B surface antigen (HBsAg) -positive cancer patients who were referred to Sun Yat-sen University Cancer Center and received an anti-PD-1/PD-L1 antibody between January 1, 2015 and July 31, 2018. The primary end point was the rate of the occurrence of HBV reactivation. RESULTS:In total, 114 eligible patients were included, among whom 90 (79%) were male, and the median (range) age was 46 (16-76) years. Six patients (5.3%) developed HBV reactivation, occurring at a median of 18 weeks (range, 3-35 weeks) from the commencement of immunotherapy. Among these patients, all of them had undetectable baseline HBV DNA; one had prophylactic antiviral therapy while five did not; four were positive for Hepatitis B e antigen while the other two were negative. At reactivation, the median HBV DNA level was 3.89 × 10 IU/mL (range, 1.80 × 10-6.00 × 10 IU/mL); five had HBV-related hepatitis and one exhibited increasing HBV DNA level without alanine transaminase elevation. No HBV-related fatal events occurred. The lack of antiviral prophylaxis was the only significant risk factor for HBV reactivation (odds ratio, 17.50 [95% CI, 1.95-157.07], P = .004). CONCLUSIONS:HBV reactivation occurs in a subset of HBsAg-positive cancer patients undergoing anti-PD-1 or anti-PD-L1 immunotherapy. Regular monitoring of HBV DNA and antiviral prophylaxis are advised to prevent this potentially fatal complication.

BACKGROUND:Patients with chronic viral infections including human immunodeficiency virus (HIV), hepatitis B (HBV) and hepatitis C (HCV) are at increased risk of developing malignancies. The safety and efficacy of ICI therapy in patients with both cancer and chronic viral infections is not well established as most clinical trials of ICIs excluded these patient populations. METHODS:We performed a retrospective analysis of patients with advanced-stage cancers and HIV, HBV, or HCV infection treated with ICI therapy at 5 MedStar Health hospitals from January 2011 to April 2018. RESULTS:We identified 50 patients including 16 HIV, 29 HBV/HCV, and 5 with concurrent HIV and either HBV or HCV. In the HIV cohort (n = 21), any grade immune-related adverse events (irAEs) were 24% with grade ≥ 3 irAEs 14%. Among 5 patients with matched pre/post-treatment results, no significant changes in HIV viral load and CD4+ T-cell counts were observed. RECIST confirmed (n = 18) overall response rate (ORR) was 28% with 2 complete responses (CR) and 3 partial responses (PR). Responders included 2 patients with low baseline CD4+ T-cell counts (40 and 77 cells/ul, respectively). In the HBV/HCV cohort (n = 34), any grade irAEs were 44% with grade ≥ 3 irAEs 29%. RECIST confirmed ORR was 21% (6 PR). Among the 6 patients with known pre/post-treatment viral titers (2 HCV and 4 HBV), there was no evidence of viral reactivation. CONCLUSIONS:Our retrospective series is one of the largest case series to report clinical outcomes among HIV, HBV and HCV patients treated with ICI therapy. Toxicity and efficacy rates were similar to those observed in patients without chronic viral infections. Viral reactivation was not observed. Tumor responses occurred in HIV patients with low CD4 T-cell counts. While prospective studies are needed to validate above findings, these data support not excluding such patients from ICI-based clinical trials or treatment.

BACKGROUND & AIMS:Systemic corticosteroids may cause HBV reactivation, but the impact on patients with previous HBV exposure is poorly defined. We aimed to study the risk of HBsAg seroreversion and hepatitis flare in patients with previous HBV exposure. METHODS:Patients who were negative for HBsAg and received corticosteroids between 2001-2010 were included. Patients who were positive for antibody to HBsAg (anti-HBs) and/or to HBcAg (anti-HBc) were defined as having previous HBV exposure. The primary endpoint was HBsAg seroreversion; the secondary endpoint was hepatitis flare (alanine aminotransferase >80 U/L) at 1 year. RESULTS:A total of 12,997 patients fulfilled the inclusion criteria: anti-HBs positive only (n = 10,561); anti-HBc positive only (n = 970); anti-HBs & anti-HBc positive (n = 830) and anti-HBs & anti-HBc negative (n = 636). HBsAg seroreversion occurred in 165 patients. Patients who were anti-HBc positive only had a higher risk of HBsAg seroreversion (1-year incidence 1.8%) than those negative for both anti-HBs & anti-HBc (0%; p = 0.014). Patients with previous HBV exposure had a similarly low risk of liver failure as unexposed individuals (1.1% vs. 0.9%). The risk of a hepatitis flare started to increase in those receiving corticosteroids at peak daily doses of 20-40 mg (adjusted hazard ratio [HR] 2.19, p = 0.048) or >40 mg (aHR 2.11, p = 0.015) prednisolone equivalents for <7 days, and was increased at treatment durations of 7-28 days and >28 days (aHR 2.02-3.85; p <0.001-0.012). CONCLUSIONS:In HBsAg-negative patients who were only anti-HBc positive, high peak daily doses of corticosteroids increased the risk of hepatitis flare, but not seroreversion. The rate of liver failure was low and similar in HBV exposed and unexposed individuals; there were no deaths, nor any requirement for liver transplantation. LAY SUMMARY:It is important to know the hepatitis B virus (HBV) status before starting corticosteroid therapy. Patients with resolved HBV infection without detectable immunity are at an increased risk of HBV surface antigen seroreversion after corticosteroid therapy. High peak daily doses of corticosteroids (>40 mg prednisolone equivalents) increase the risk of hepatitis flare, but not seroreversion, in patients with previous exposure to HBV, irrespective of the duration of treatment. Interval monitoring of liver biochemistries is essential for the early detection of hepatitis flares in these patients.

Hepatology (Baltimore, Md.)
Reactivation of hepatitis B virus (HBV) has been reported in hepatitis C virus-infected individuals receiving direct-acting antiviral (DAA) therapy. The overall risk among patients with current or prior HBV infection in the context of DAA treatment is unknown. The aim of this evaluation was to identify and characterize HBV reactivation among veterans treated with oral DAA therapy. This retrospective evaluation included 62,290 hepatitis C virus-infected veterans completing oral DAA treatment. Baseline HBV infection status for each veteran was identified from HBV laboratory data performed prior to DAA initiation. To assess for HBV reactivation and hepatitis we identified all hepatitis B surface antigen (HBsAg), HBV DNA, and alanine aminotransferase results obtained while on DAA treatment or 7 days after. HBV reactivation was defined as a >1000 IU/mL increase in HBV DNA or HBsAg detection in a person who was previously negative. Prior to DAA treatment 85.5% (53,784/62,920) had HBsAg testing and 0.70% (377/53,784) were positive; 84.6% (53,237/62,920) had a hepatitis B surface antibody test, of which 42.2% (22,479/53,237) were positive. In all, 9 of 62,290 patients treated with DAAs had evidence of HBV reactivation occurring while on DAA treatment. Eight occurred in patients known to be HBsAg-positive, and 1 occurred in a patient known to be isolated hepatitis B core antibody-positive. Seventeen other patients had small increases in HBV DNA levels that did not qualify as HBV reactivation. Only 3 of the 9 patients identified with HBV reactivation in this cohort exhibited peak alanine aminotransferase elevations >2 times the upper limit of normal. CONCLUSION:HBV reactivation of varying severity, even in the setting of isolated hepatitis B core antibody, with or without accompanying hepatitis can occur-though the occurrence of accompanying severe hepatitis was rare.

Annals of internal medicine
BACKGROUND:Solid tumor chemotherapy regimens pose a risk for hepatitis B virus (HBV) reactivation, but screening and antiviral prophylaxis remains controversial because of insufficient evidence. PURPOSE:To determine the risk for HBV reactivation with and without antiviral prophylaxis and the effectiveness of prophylaxis in adults with solid tumors and chronic or resolved HBV infection. DATA SOURCES:MEDLINE through 1 July 2015 and Web of Science, Cochrane Central Register of Controlled Trials, TOXNET, and Scopus through 1 March 2015. STUDY SELECTION:26 English-language observational studies and randomized, controlled trials in patients with chronic or resolved HBV receiving chemotherapy for solid tumors. DATA EXTRACTION:Study characteristics, quality, and risk of bias were assessed by 1 researcher and verified by another independent researcher. DATA SYNTHESIS:Random-effects model meta-analyses were used to estimate the risk and odds ratio (OR) of reactivation with versus without antiviral prophylaxis. Reactivation in chronic HBV without prophylaxis ranged from 4% to 68% (median, 25%) with substantial heterogeneity. Prophylaxis reduced the risk for HBV reactivation (OR, 0.12 [95% CI, 0.06 to 0.22]), HBV-related hepatitis (OR, 0.18 [CI, 0.10 to 0.32]), and chemotherapy interruption (OR, 0.10 [CI, 0.04 to 0.27]). In 3 studies of patients with resolved HBV infection, none received HBV prophylaxis and reactivation risk ranged from 0.3% to 9.0%. LIMITATIONS:Significant heterogeneity in underlying study populations and treatment regimens, incomplete baseline data, possibility of publication bias, and limited study quality. Most studies were observational and from Asia. CONCLUSION:In patients with chronic HBV receiving solid tumor chemotherapy, the risk for HBV reactivation is similar to the risk with other types of immunosuppressive therapy. Results support HBV screening and antiviral prophylaxis before initiation of chemotherapy for solid tumors.

Annals of oncology : official journal of the European Society for Medical Oncology
BACKGROUND:Hepatitis B virus (HBV) reactivation is a well-known risk during chemotherapy for hematological malignancies with reported rates ranging between 14% and 72%. However, there is a paucity of data regarding HBV infection management and reactivation risk in patients receiving systemic treatments for solid tumors. DESIGN:We conducted a PubMed search for publications from January 1990 until May 2016 related to HBV reactivation. The search terms were 'hepatitis B reactivation', cross-referenced with 'chemotherapy', then 'hepatitis B' cross-referenced with International Non-proprietary Name of each of the most used chemotherapy drugs in solid tumors. RESULTS:From these data, a grading of HBV reactivation risk and recommendations for management are given for most frequently used anticancer drugs in solid tumors. CONCLUSION:Most drugs used for the treatment of solid tumors can induce hepatitis B reactivation in HBs antigen-positive patients. HBV screening can be recommended before systemic treatment initiation. Pre-emptive antiviral treatment can reduce the risk of HBV reactivation and prevent chemotherapy disruption.

BACKGROUND & AIMS:Treatment with direct-acting antiviral (DAA) agents can reduce Model for End-Stage Liver Disease and Child-Pugh-Turcotte (CPT) scores in patients with decompensated cirrhosis caused by hepatitis C virus. However, many of these patients still die or require liver transplantation. We collected data on baseline features of patients and aimed to develop a scoring system to predict response to DAA therapy. METHODS:We performed a retrospective analysis of data from 4 trials on the effects of sofosbuvir-based therapy in patients with hepatitis C virus-associated decompensated cirrhosis (502 of CPT class B and 120 of CPT class C). In these trials, patients were given 12 or 24 weeks of treatment with ledipasvir, sofosbuvir, and ribavirin or velpatasvir, sofosbuvir, and/or ribavirin, or 48 weeks of treatment with sofosbuvir and ribavirin. We collected demographic, clinical, treatment response, and laboratory data from patients and tested their associations with patient outcomes at 36 weeks. The primary outcome was factors associated with reduction of CPT score to class A. RESULTS:The presence of ascites or encephalopathy, serum level of albumin <3.5 g/dL or alanine aminotransferase <60 U/L, and body mass index >25 kg/m were associated with an increased risk of not achieving a reduction in CPT to class A, independent of sustained viral response to therapy. Serum level of albumin <2.8 g/dL and abnormal level of bilirubin were associated with an increased risk of liver transplantation or death. We developed a scoring system based on 5 baseline factors (body mass index, encephalopathy, ascites, and serum levels of alanine aminotransferase and albumin) associated significantly with patient outcomes, which we called the "BE3A score." For patients with scores of 4-5, the hazard ratio for reduction of CPT score to class A was 52.3 (95% confidence interval, 15.2-179.7). CONCLUSIONS:We identified 5 baseline factors (body mass index, encephalopathy, ascites, and serum levels of alanine aminotransferase and albumin) associated with a reduction of CPT score to class A in patients with hepatitis C virus-associated decompensated cirrhosis receiving DAA therapy. We developed a predictive score using these factors, called the BE3A score, which can be used as a shared decision-making tool, quantifying the potential benefits of DAA therapy for patients with decompensated cirrhosis.
