Abstract
OBJECTIVES Criteria for antiviral treatment initiation in Thailand were complex and difficult to implement. This study determined the cost-effectiveness of 2 simplified antiviral treatment initiation criteria among patients with chronic hepatitis B in Thailand. METHODS A hybrid model of the decision tree and Markov model was developed. Two simplified antiviral treatment initiation criteria were the expanded criteria, treating patients with hepatitis B surface antigen positive and viral load (hepatitis B virus deoxyribonucleic acid) >2000 IU/mL or cirrhosis by tenofovir alafenamide (TAF), and the test-and-treat criteria, treating patients with hepatitis B surface antigen positive and viral load >10 IU/mL or cirrhosis by TAF. PubMed was searched from its inception to July 2023 to identify input parameters. Best supportive care was chosen for patients who were ineligible for TAF. Incremental cost-effectiveness ratio per quality-adjusted life-year (QALY) was calculated. RESULTS The expanded criteria and the test-and-treat could reduce the occurrence of patients progressing to hepatocellular carcinoma. In particular, both criteria could reduce 4846 new cases of hepatocellular carcinoma per 100 000 patients. The incremental cost-effectiveness ratios for the expanded criteria and the test-and-treat criteria were 24 838 Thai baht (THB)/QALY and 163 060 THB/QALY, respectively. CONCLUSIONS At the current willingness to pay of 160 000 THB/QALY, the expanded criteria were cost-effective, but the test-and-treat criteria were not cost-effective to be the simplified antiviral treatment initiation criteria for patients with chronic hepatitis B in Thailand.

Abstract
Background Hepatitis B virus (HBV) infection is a serious public health issue that must be addressed. Aim The goal of this study was to investigate the correlation between serological status for hepatitis Be antigen (HBeAg)/anti-HBe, serum transaminase levels, and serum HBV-DNA in patients with chronic HBV infection. Methods A retrospective observational study with 620 patients with persistent HBV infection (mean age, 36.35 years; 506 men) was conducted. All patients tested positive for hepatitis B surface antigen (HBsAg). Liver profile, HBeAg, and anti-HBe antibody tests were conducted for all patients. Additionally, serum HBV DNA was examined using a DNA assay in these individuals. Results Of 620 patients, 114 (18.39%) were HBeAg-positive and 506 (81.61%) HBeAg-negative. A detectable level of HBV DNA was found in 89.79% of HBeAg-positive/anti-HBe negative patients compared to HBeAg-negative/anti-HBe positive carriers 33.69% (P value <0.0001). The median viral load was significantly higher in HBeAg-positive cases (4.72 log10 copies/mL) than in HBeAg-negative individuals (4.23 log10 copies/mL; P = 0.997). Additionally, a higher proportion of HBeAg-positive samples (P = 0.0001) had HBV-DNA levels above 10,000 copies/mL.

Abstract
More than 290 million people worldwide, and almost 2 million people in the United States, are infected with hepatitis B virus, which can lead to chronic hepatitis B, a vaccine-preventable communicable disease. The prevalence of chronic hepatitis B infection in pregnancy is estimated to be 0.7% to 0.9% in the United States, with >25,000 infants born annually at risk for chronic infection due to perinatal transmission. Given the burden of disease associated with chronic hepatitis B infection, recent national guidance has expanded both the indications for screening for hepatitis B infection and immunity and the indications for vaccination. The purpose of this document is to aid clinicians caring for pregnant patients in screening for hepatitis B infection and immunity status, discuss the perinatal risks of hepatitis B infection in pregnancy, determine whether treatment is indicated for maternal or perinatal indications, and recommend hepatitis B vaccination among susceptible patients. The following are the Society for Maternal-Fetal Medicine recommendations: (1) we recommend triple-panel testing (hepatitis B surface antigen screening, antibody to hepatitis B surface antigen, and total antibody to hepatitis B core antigen) at the initial prenatal visit if not previously documented or known to have been performed (GRADE 1C); (2) we recommend universal hepatitis B surface antigen screening alone at the initial prenatal care visit for all pregnancies where there has been a previously documented negative triple-panel test (GRADE 1B); (3) we recommend that individuals with unknown hepatitis B surface antigen screening status be tested on any presentation for care in pregnancy; we also recommend that those with clinical hepatitis or those with risk factors for acute hepatitis B infection be tested at the time of admission to a birthing facility when delivery is anticipated (GRADE 1B); (4) we do not recommend altering routine intrapartum care in individuals chronically infected with hepatitis B; administration of neonatal immunoprophylaxis is standard of care in these situations (GRADE 1B); (5) we do not recommend cesarean delivery for the sole indication of reducing perinatal hepatitis B virus transmission (GRADE 1B); (6) we recommend that individuals with HBV infection can breastfeed as long as the infant has received immunoprophylaxis at birth (GRADE 1C); (7) we suggest individuals with hepatitis B infection who desire invasive testing may have the procedure performed after an informed discussion on risks and benefits in the context of shared decision-making and in the context of how testing will affect clinical care (GRADE 2C); (8) in individuals with hepatitis viral loads >200,000 IU/mL (>5.3 log 10 IU/mL), we recommend antiretroviral therapy with tenofovir (tenofovir alafenamide at 25 mg daily or tenofovir disoproxil fumarate at 300 mg daily) in the third trimester (initiated at 28-32 weeks of gestation) as an adjunctive strategy to immunoprophylaxis to reduce perinatal transmission (GRADE 1B); (9) we recommend administering hepatitis B vaccine and hepatitis B immunoglobin within 12 hours of birth to all newborns of hepatitis B surface antigen-positive pregnant patients or those with unknown or undocumented hepatitis B surface antigen status, regardless of whether antiviral therapy has been given during the pregnancy to the pregnant patient (GRADE 1B); and (10) we recommend hepatitis B vaccination in pregnancy for all individuals without serologic evidence of immunity or documented history of vaccination (GRADE 1C).

Cost-effectiveness of switching from tenofovir disoproxil fumarate to tenofovir alafenamide versus entecavir for chronic hepatitis B patients in Greece. J Comp Eff Res 2024; 13:e230090. [PMID: 38317634 PMCID: PMC11044955 DOI: 10.57264/cer-2023-0090] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2023] [Accepted: 01/18/2024] [Indexed: 02/07/2024] Open
Abstract
Aim: This study assessed the clinical impact and cost-effectiveness of switching from tenofovir disoproxil fumarate (TDF) to either tenofovir alafenamide (TAF) or entecavir (ETV) in a Greek chronic hepatitis B (CHB) population. Patients & methods: A Markov model from the perspective of a third-party payer in Greece quantified the health and economic benefits of switching from TDF to either TAF or ETV over a lifetime horizon. Results: Over a lifetime, patients who switch from TDF to TAF versus patients who switch from TDF to ETV had an overall lower incidence of compensated cirrhosis (0.4% lower), decompensated cirrhosis (0.04% lower) and hepatocellular carcinoma (0.25% lower). Chronic kidney disease and end-stage renal disease were also lower in patients who switch to TAF; major osteoporotic fractures were similar for both groups. While total costs were higher for switching from TDF to TAF versus TDF to ETV due to the higher cost of TAF, switching from TDF to TAF versus ETV was cost effective with an incremental cost-effectiveness ratio of €17,113 per quality-adjusted life year. Conclusion: Switching from TDF to TAF in patients living with CHB is a cost effective strategy to reduce adverse liver disease outcomes, while improving bone- and renal-related safety outcomes.

Using the AS04C-adjuvanted hepatitis B vaccine in patients classified as non-responders. Trans R Soc Trop Med Hyg 2024; 118:170-177.

Abstract
BACKGROUND Chronic hepatitis B (HB) remains a significant global health concern, despite the widespread availability of the HB vaccine. While the standard vaccine demonstrates an impressive serological response rate exceeding 90%, a subset of individuals exhibit suboptimal immunity. This study aims to elucidate the efficacy of the AS04C-adjuvanted HB vaccine in addressing non-responsiveness. METHODS Conducted at the Preventive Medicine Service of the University Albacete Hospital in Spain from 2017 to 2021, this single-center observational study enrolled 195 patients. Among them, 126 (65%) were classified as non-responders following one or two complete standard vaccination courses. RESULTS After the administration of a complete four-dose regimen of the AS04C-adjuvanted vaccine, 73.81% of non-responder patients exhibited antibody titers indicative of robust immunity (anti-HBs >10). CONCLUSIONS These findings underscore the pivotal role of the AS04C-adjuvanted HB vaccine in addressing non-responsiveness, emphasizing its potential as a crucial tool in augmenting immunization strategies for various populations. This includes non-responders to standard vaccination, individuals with chronic kidney disease, those requiring seroprotection due to factors like immunosuppression or occupational hazards, as well as patients for whom conventional revaccination strategies have proven futile. Additional research is needed to expand on the promising results obtained through our protocol.

Abstract
BACKGROUND Ambient particulate matter is classified as a human Class 1 carcinogen, and recent studies found a positive relationship between fine particulate matter (PM2.5) and liver cancer. Nevertheless, little is known about which specific metal constituent contributes to the development of liver cancer. OBJECTIVE To evaluate the association of long-term exposure to metal constituents in PM2.5 with the risk of liver cancer using a Taiwanese cohort study. METHODS A total of 13,511 Taiwanese participants were recruited from the REVEAL-HBV in 1991-1992. Participants' long-term exposure to eight metal constituents (Ba, Cu, Mn, Sb, Zn, Pb, Ni, and Cd) in PM2.5 was based on ambient measurement in 2002-2006 followed by a land-use regression model for spatial interpolation. We ascertained newly developed liver cancer (ie, hepatocellular carcinoma [HCC]) through data linkage with the Taiwan Cancer Registry and national health death certification in 1991-2014. A Cox proportional hazards model was utilized to assess the association between exposure to PM2.5 metal component and HCC. RESULTS We identified 322 newly developed HCC with a median follow-up of 23.1 years. Long-term exposure to PM2.5 Cu was positively associated with a risk of liver cancer. The adjusted hazard ratio (HR) was 1.13 (95% confidence interval [CI], 1.02-1.25; P = 0.023) with one unit increment on Cu normalized by PM2.5 mass concentration in the logarithmic scale. The PM2.5 Cu-HCC association remained statistically significant with adjustment for co-exposures to other metal constituents in PM2.5. CONCLUSION Our findings suggest PM2.5 containing Cu may attribute to the association of PM2.5 exposure with liver cancer.

Abstract
OBJECTIVES Detailed simulation models are needed to assess strategies for prevention and treatment of hepatitis B virus (HBV) infection, the world's leading cause of liver disease. We sought to develop and validate a simulation model of chronic HBV that incorporates virological, serological and clinical outcomes. METHODS We developed a novel Monte Carlo simulation model (the HEPA-B Model) detailing the natural history of chronic HBV. We parameterised the model with epidemiological data from the Western Pacific and sub-Saharan Africa. We simulated the evolution of HBV DNA, 'e' antigen (HBeAg) and surface antigen (HBsAg). We projected incidence of HBeAg loss, HBsAg loss, cirrhosis, hepatocellular carcinoma (HCC) and death over 10-year and lifetime horizons. We stratified outcomes by five HBV DNA categories at the time of HBeAg loss, ranging from HBV DNA<300 copies/mL to >106 copies/mL. We tested goodness of fit using intraclass coefficients (ICC). RESULTS Model-projected incidence of HBeAg loss was 5.18% per year over lifetime (ICC, 0.969 (95% CI: 0.728 to 0.990)). For people in HBeAg-negative phases of infection, model-projected HBsAg loss ranged from 0.78% to 3.34% per year depending on HBV DNA level (ICC, 0.889 (95% CI: 0.542 to 0.959)). Model-projected incidence of cirrhosis was 0.29-2.09% per year (ICC, 0.965 (95% CI: 0.942 to 0.979)) and HCC incidence was 0.06-1.65% per year (ICC, 0.977 (95% CI: 0.962 to 0.986)). Over a lifetime simulation of HBV disease, mortality rates were higher for people with older age, higher HBV DNA level and liver-related complications, consistent with observational studies. CONCLUSIONS We simulated HBV DNA-stratified clinical outcomes with the novel HEPA-B Model and validated them to observational data. This model can be used to examine strategies of HBV prevention and management.

Abstract
Hepatocellular carcinoma (HCC) accounts for the majority of primary liver cancers and represents a global health challenge. Liver cancer ranks third in cancer-related mortality with 830,000 deaths and sixth in incidence with 906,000 new cases annually worldwide. HCC most commonly occurs in patients with underlying liver disease, especially chronic hepatitis B virus (HBV) infection in highly endemic areas. Predicting HCC risk based on scoring models for patients with chronic liver disease is a simple, effective strategy for identifying and stratifying patients to improve the early diagnosis rate and prognosis of HCC. We examined 23 HCC risk scores published worldwide in CHB patients with (n=10) or without (n=13) antiviral treatment. We also described the characteristics of the risk score's predictive performance and application status. In the future, higher predictive accuracy could be achieved by combining novel technologies and machine learning algorithms to develop and update HCC risk score models and integrated early warning and diagnosis systems for HCC in hospitals and communities.

Abstract
The epidemiology, natural history, and therapeutic responses of chronic liver diseases and liver lesions often vary by sex. In this review, we summarize available clinical and translational data on these aspects of the most common liver conditions encountered in clinical practice, including the potential contributions of sex hormones to the underlying pathophysiology of observed differences. We also highlight areas of notable knowledge gaps and discuss sex disparities in access to liver transplant and potential strategies to address these barriers. Given established sex differences in immune response, drug metabolism, and response to liver-related therapies, emerging clinical trials and epidemiological studies should prioritize dedicated analyses by sex to inform sex-specific approaches to liver-related care.

Abstract
Chronic hepatitis B (CHB) is the most common cause of hepatocellular carcinoma (HCC) worldwide. Antiviral treatment reduces the risk of HCC and mortality; nonetheless, globally in 2019, only 2.2% of CHB patients received treatment. Current international CHB guidelines recommend antiviral treatment only in subsets of patients with clear evidence of liver damage. This contrasts with hepatitis C or HIV where early treatment is recommended in all infected patients, regardless of end-organ damage. This narrative review aims to provide an overview of data on the early initiation of antiviral treatment and its related potential economic impact. Literature searches were performed using PubMed and abstracts from international liver congresses (2019-2021). Data on risk of disease progression and HCC and the impact of antiviral treatment in currently ineligible patients were summarized. Cost-effectiveness data on early antiviral treatment initiation were also collated. Accumulating molecular, clinical, and economic data suggest that early initiation of antiviral treatment could save many lives through HCC prevention in a highly cost-effective manner. In light of these data, we consider several alternative expanded treatment strategies that might further a simplified 'treatment as prevention' approach.

Abstract
BACKGROUND Hepatitis B virus (HBV) core protein-targeting antivirals (CpTAs) are promising therapeutic agents for treating chronic hepatitis B (CHB). In this study, the antiviral activity, pharmacokinetics (PK), and tolerability of ZM-H1505R (Canocapavir), a chemically unique HBV CpTA, were evaluated in patients with CHB. METHODS This study was a double-blind, randomized, placebo-controlled phase 1b trial in Chinese CHB patients. Noncirrhotic and treatment-naive CHB patients were divided into three cohorts (10 patients per cohort) and randomized within each cohort in a ratio of 4:1 to receive a single dose of 50, 100, or 200 mg of Canocapavir or placebo once a day for 28 consecutive days. RESULTS Canocapavir was well tolerated, with the majority of adverse reactions being grade I or II in severity. There were no serious adverse events, and no patients withdrew from the study. Corresponding to 50, 100, and 200 mg doses of Canocapavir, the mean plasma trough concentrations of the drug were 2.7-, 7.0-, and 14.6-fold of its protein-binding adjusted HBV DNA EC50 (135 ng/mL), respectively, with linear PK and a low-to-mild accumulation rate (1.26-1.99). After 28 days of treatment, the mean maximum HBV DNA declines from baseline were -1.54, -2.50, -2.75, and -0.47 log10 IU/mL for the 50, 100, and 200 mg of Canocapavir or placebo groups, respectively; and the mean maximum pregenomic RNA declines from baseline were -1.53, -2.35, -2.34, and -0.17 log10 copies/mL, respectively. CONCLUSIONS Canocapavir treatment is tolerated with efficacious antiviral activity in CHB patients, supporting its further development in treating HBV infection.

Abstract
Causal mediation analysis is advantageous for mechanism investigation. In settings with multiple causally ordered mediators, path-specific effects have been introduced to specify the effects of certain combinations of mediators. However, most path-specific effects are unidentifiable. An interventional analog of path-specific effects is adapted to address the non-identifiability problem. Moreover, previous studies only focused on cases with two or three mediators due to the complexity of the mediation formula in a large number of mediators. In this study, we provide a generalized definition of traditional path-specific effects and interventional path-specific effects with a recursive formula, along with the required assumptions for nonparametric identification. Subsequently, a general approach is developed with an arbitrary number of multiple ordered mediators and with time-varying confounders. All methods and software proposed in this study contribute to comprehensively decomposing a causal effect confirmed by data science and help disentangling causal mechanisms in the presence of complicated causal structures among multiple mediators.

Abstract
BACKGROUND In people with hepatitis B virus (HBV) infection, persistence of hepatitis B e antigen (HBeAg) is associated with clinical progression and need for treatment. HBeAg loss represents partial immune control and is a critical event in the natural history of chronic HBV. METHODS We conducted a systematic review and meta-analysis of cohort studies that report HBeAg loss among people with untreated chronic HBV. We evaluated HBeAg loss using a random-effects model and conducted subanalysis on region. RESULTS We screened 10 560 publications, performed 196 full-text analyses, and included 26 studies for meta-analysis. The pooled rate of HBeAg loss was 6.46/100 person-years (PYs) (95% confidence interval, 5.17-8.08). Meta-regression showed that older age of participants and studies in Europe were associated with higher rate of HBeAg loss. Rates per 100 PYs were 7.43 (95% confidence interval, 6.30-8.75; 1 study) in Africa, 3.24 (2.61--4.02; 1 study) in the Eastern Mediterranean, 13.67 (11.21-16.66; 4 studies) in Europe, 7.34 (4.61--11.70; 5 studies) in North America, and 5.53 (4.05--7.55; 15 studies) in the Western Pacific. CONCLUSIONS Spontaneous HBeAg loss occurs at a rate of 6.46/100 PYs. Variations by region and age group may reflect epidemiological, immunological, or HBV genotype-related differences.

Abstract
The majority of Australia's hepatitis B virus (HBV) burden is borne by culturally and linguistically diverse (CALD) populations, and antiviral treatment is the mainstay of intervention. Using modelling, we estimated the impact of targeted antiviral treatment scale-up and changes in migration on HBV-related mortality and HBV elimination in CALD populations in Australia. We fitted a deterministic mathematical model based on the natural history of HBV and the Australian migration effect in four CALD population groups according to country of birth. We used three antiviral treatment scale-up scenarios: baseline (9.3% coverage); intermediate (coverage of 80% of patients eligible for antiviral therapy by 2030); and optimistic (coverage of 20% of all patients living with HBV by 2022). Our model predicted that if the baseline treatment is followed between 2015 and 2030, the number of chronic HBV cases and HBV-related mortality will increase. Following the optimistic scale-up, the number of new HBV cases could be reduced by 78%, 73%, 74% and 83% in people born in Asia-Pacific, Europe, Africa and the Middle East, and Americas, respectively, between 2015 and 2030. An optimistic treatment scale-up could result in a 19.2%-24.5% reduction in HBV-related mortality and a 15%-25% reduction in HCC-related mortality in CALD populations between 2015 and 2030. In conclusion, our findings highlight that targeted antiviral treatment for CALD populations provides significant health system benefits by reducing HBV-related complications from cirrhosis and HCC. Expanded antiviral treatment programmes focusing on high-prevalence CALD populations may be an effective strategy to reduce HBV-related morbidity and mortality.

Abstract
PURPOSE Population attributable fraction (PAF), defined as the proportion of the occurrence of a disease which will be reduced by eliminating risk factors in a population, is one of the most common measurements for evaluating the benefit of a health-related policy in epidemiologic study. In this article, we propose an alternative PAF defined based on sufficient cause framework, which decompose the occurrence of a disease into several pathways including mediation and mechanistic interaction. METHODS We propose a formal statistical definition and regression-based estimator for PAF based on sufficient cause framework within mediation settings. Under monotonicity assumption, the proposed method can decompose the occurrence of a disease into nine PAFs corresponding to all types of mechanisms attributing to exposure and the mediator, including the portion attributing to exposure directly, to mediator, to indirect effect through mediator, to the mechanistic interaction, to both of mediation and interaction, and to none of exposure or mediator. RESULTS We apply the proposed method to explore the mechanism of a hepatitis C virus (HCV)-induced hepatocellular carcinoma (HCC) mediated by and/or interacted with alanine aminotransferase (ALT) and hepatitis B virus (HBV). When treating ALT as mediator, 56.77% of diseased subjects can be attributable to either HCV or abnormal ALT. When treating HBV as mediator, HCC is mainly induced by an exogenous high HBV viral load directly. CONCLUSIONS The proposed method can identify the impact of exposure and pathway effects, and benefit to allocate the resources on intervention strategies.

Abstract
The study aimed to determine adjusted all-cause mortality and cause of death in persons with chronic hepatitis B virus (HBV) infection compared with age- and sex-matched persons from the general population. We used nationwide registers to identify persons aged ≥18 years with chronic HBV infection in 2002-2017 in Denmark and included 10 age- and sex-matched controls for each. Follow-up was from 6 months after diagnosis until death, emigration, or 31 December 2017. Mortality rate ratios (MRRs) adjusted for age, sex, employment, origin and comorbidity were calculated using Poisson regression. Unadjusted cause-specific mortality rate ratios with 95% confidence intervals were calculated assuming a Poisson distribution. A total of 6988 persons with chronic HBV infection and 69,847 controls were included. During a median follow-up of 7.7 years (range 0.0-15.5), 315 (5%) persons with-and 1525 (2%) without-chronic HBV infection died. The adjusted all-cause MRR was 1.5 (95% CI 1.2-2.0). Persons with chronic HBV infection had increased mortality due to liver disease including hepatocellular carcinoma (MRR 12.3 [8.6-17.7]), external causes (MRR 3.3 [2.5-4.7]), endocrine disease (MRR 3.2 [1.8-5.4]), genitourinary disease (MRR 3.2 [1.2-7.6]) and neoplasms (except hepatocellular carcinoma; MRR 1.6 [1.2-2.0]). In conclusion, this study showed an increased all-cause mortality in persons with chronic HBV infection in comparison with age- and sex-matched persons without chronic HBV infection which remained after adjustment for several confounding factors. Excess mortality was mainly associated with liver disease, but also external factors, endocrine disease, genitourinary disease and neoplasms (excluding hepatocellular carcinoma).

[PMID: 35817068 PMCID: PMC9339532 DOI: 10.1016/s2352-3018(22)00123-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/14/2022] [Revised: 03/18/2022] [Accepted: 04/20/2022] [Indexed: 12/20/2022]
Abstract
Individuals with chronic hepatitis B virus (HBV) infection who are at substantial risk of HIV acquisition benefit from pre-exposure prophylaxis (PrEP) with tenofovir-based antiviral therapy. Considering that tenofovir potently inhibits HBV, providing PrEP to individuals with HBV effectively results in treatment of their HBV infection. However, some clinicians might be hesitant to initiate PrEP in people with chronic HBV due to unknown risks of HBV reactivation, hepatitis, and acute liver failure during periods of antiviral cessation. Unfortunately, these knowledge gaps affect scale up of PrEP among people with chronic HBV. Emerging data regarding the risks and benefits of antiviral cessation in people with chronic HBV suggest that PrEP can be safely initiated despite the risks of non-adherence or discontinuation. People with chronic HBV who stop PrEP should be closely monitored for HBV reactivation and hepatitis flares after antiviral cessation.

[PMID: 34855999 DOI: 10.1002/hep.32265] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/23/2021] [Revised: 11/07/2021] [Accepted: 11/25/2021] [Indexed: 12/15/2022]
Abstract
BACKGROUND AND AIMS Hepatitis B vaccine has been included in the infant immunization schedule since 1991 in the United States. We aimed to assess its effectiveness against HBV infection and its impact on mortality. APPROACH AND RESULTS The study population was participants aged 6+ years with an HBV vaccination history and an HBV serologic test from the National Health and Nutrition Examination Survey, 1999-2018. Participants aged 18+ years with linked mortality records from 1999-2014 were followed for mortality analysis. Multivariable logistic regression was used to compute vaccine effectiveness (VE) overall, by year of birth, and by age. Cox regression was used to estimate HRs for all-cause, cancer-related, and cardiovascular disease-related mortality. A total of 64,107 participants were included in the main analysis, with 29,600 (40.7%) having completed HBV vaccination (three or more doses, vaccinated). The highest vaccination uptake was found among those born after 1991, at 86.5%. Vaccinated participants had higher prevalence of vaccine-induced immunity than the unvaccinated (47.2% vs. 7.4%). Among those born after 1991, VE was found at 58% (95% CI, 18%-79%) overall and 85% for those aged ≥20 years (mean age, 22), whereas no effect was found among those born prior to 1990. HBV vaccination was associated with reduced risk of all-cause mortality (HR, 0.78; 95% CI, 0.68-0.90) and cancer-related mortality (HR, 0.76; 95% CI, 0.58-1.00) but not for cardiovascular disease-related mortality. CONCLUSIONS In the universal infant vaccination era, the HBV vaccine has shown substantial effectiveness against HBV infection and maintained strong protection for 20 years. It was also associated with reduced risk of all-cause and cancer-related mortality.

Better survival of patients with hepatitis B virus-related hepatocellular carcinoma in South Korea: Changes in 16-years cohorts. PLoS One 2022; 17:e0265668. [PMID: 35324973 PMCID: PMC8947113 DOI: 10.1371/journal.pone.0265668] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2021] [Accepted: 03/02/2022] [Indexed: 02/06/2023] Open
Abstract
Aims The incidence and mortality of hepatocellular carcinoma (HCC) have decreased over time in South Korea, where hepatitis B virus (HBV) in endemic. This study investigated the changes in the characteristics and clinical outcomes of HCC patients in Korea. Methods Patients initially diagnosed with HCC and treated at the National Cancer Center, Korea between 2000 and 2015 (n = 4,291) were followed up until February 2017. Differences in patient characteristics and outcomes were compared between chronological cohorts: cohort A (2000–2004, n = 1,157) vs. B (2005–2009, n = 1,678) vs. C (2010–2015, n = 1,456). Results The median age of the patient cohort was 57 years (range, 13–98 years), and male predominance was noted (81.6%). HBV infection was the most common etiology (74.8%). The proportion of patients diagnosed with good liver function and small tumors (<2 cm) increased significantly over time: 74.6%, 79.9%, and 87.4% for Child–Pugh class A (p<0.001) and 8.0%, 8.5%, and 12.0% for modified UICC stage I (p<0.001) in cohorts A, B, and C, respectively. Median overall survival improved significantly over time: 14.4 months (95% confidence interval [CI], 12.0–16.8 months), 22.9 months (95% CI, 20.3–25.5 months), and 53.6 months (95% CI, 45.7–61.5 months) in cohorts A, B, and C, respectively. HBV-related patients showed significantly improved survival (12.7 vs. 20.4 vs. 64.5 months, p<0.001) associated with the use of antiviral treatments (adjusted hazard ratio, 0.72; 95% CI, 0.64–0.80). Conclusions The survival of patients with HCC, especially HBV-related HCC, has improved significantly over time in Korea.

G-Computation to Causal Mediation Analysis With Sequential Multiple Mediators-Investigating the Vulnerable Time Window of HBV Activity for the Mechanism of HCV Induced Hepatocellular Carcinoma. Front Public Health 2022; 9:757942.

Abstract
Regression-based approaches are widely used in causal mediation analysis. The presence of multiple mediators, however, increases the complexity and difficulty of mediation analysis. In such cases, regression-based approaches cannot efficiently address estimation issues. Hence, a flexible approach to mediation analysis is needed. Therefore, we developed a method for using g-computation algorithm to conduct causal mediation analysis in the presence of multiple ordered mediators. Compared to regression-based approaches, the proposed simulation-based approach increases flexibility in the choice of models and increases the range of the outcome scale. The Taiwanese Cohort Study dataset was used to evaluate the efficacy of the proposed approach for investigating the mediating role of early and late HBV viral load in the effect of HCV infection on hepatocellular carcinoma (HCC) in HBV seropositive patients (n = 2,878; HCV carrier n = 123). Our results indicated that early HBV viral load had a negative mediating role in HCV-induced HCC. Additionally, early exposure to a low HBV viral load affected HCC through a lag effect on HCC incidence [OR = 0.873, 95% CI = (0.853, 0.893)], and the effect of early exposure to a low HBV viral load on HCC incidence was slightly larger than that of a persistently low viral load on HCC incidence [OR = 0.918, 95% CI = (0.896, 0.941)].

Abstract
Hepatitis B virus (HBV) is a hepatotropic virus and an important human pathogen. There are an estimated 296 million people in the world that are chronically infected by this virus, and many of them will develop severe liver diseases including hepatitis, cirrhosis and hepatocellular carcinoma (HCC). HBV is a small DNA virus that replicates via the reverse transcription pathway. In this review, we summarize the molecular pathways that govern the replication of HBV and its interactions with host cells. We also discuss viral and non-viral factors that are associated with HBV-induced carcinogenesis and pathogenesis, as well as the role of host immune responses in HBV persistence and liver pathogenesis.

Abstract
Background & Aims We aim to describe the liver immune microenvironment by analyzing liver biopsies from patients with chronic HBV infection (CHB). Host immune cell signatures and their corresponding localization were characterized by analyzing the intrahepatic transcriptome in combination with a custom multiplex immunofluorescence panel. Method Matching FFPE and fresh frozen liver biopsies were collected from immune active patients within the open-label phase IV study GS-US-174-0149. RNA-Seq was conducted on 53 CHB liver biopsies from 46 patients. Twenty-eight of the 53 samples had matched FFPE biopsies and were stained with a 12-plex panel including cell segmentation, immune and viral biomarkers. Corresponding serum samples were screened using the MSD Human V-plex Screen Service to identify peripheral correlates for the immune microenvironment. Results Using unsupervised clustering of the transcriptome, we reveal two unique liver immune signatures classified as immune high and immune low based on the quantification of the liver infiltrate gene signatures. Multiplex immunofluorescence analysis demonstrated large periportal lymphoid aggregates in immune high samples consisting of CD4 and CD8 T cells, B cells and macrophages. Differentiation of the high and low immune microenvironments was independent of HBeAg status and peripheral viral antigen levels. In addition, longitudinal analysis indicates that treatment and normalization of ALT correlates with a decrease in liver immune infiltrate and inflammation. Finally, we screened a panel of peripheral biomarkers and identified ICAM-1 and CXCL10 as biomarkers that strongly correlate with these unique immune microenvironments. Conclusion These data provide a description of immune phenotypes in patients with CHB and show that immune responses are downregulated in the liver following nucleotide analogue treatment. This may have important implications for both the safety and efficacy of immune modulator programs aimed at HBV cure. Lay summary Liver biopsies from patients with chronic hepatitis B were submitted to RNA-Seq and multiplex immunofluorescence and identified two different liver immune microenvironments: immune high and immune low. Immune high patients showed elevated immune pathways, including interferon signaling pathways, and increase presence of immune cells. Longitudinal analysis of biopsies from treatment experienced patients showed that treatment correlates with a marked decrease in inflammation and these findings may have important implications for both safety and efficacy of immune modulator programs for HBV cure.

Abstract
Accurate risk prediction for hepatocellular carcinoma (HCC) among patients with chronic hepatitis B (CHB) may guide treatment strategies including initiation of antiviral therapy and also inform implementation of HCC surveillance. There have been 26 risk scores developed to predict HCC in CHB patients with (n = 14) or without (n = 12) receiving antiviral treatment; all of them invariably include age in the scoring formula. Virological biomarkers of replicative activities (i.e., hepatitis B virus DNA level or hepatitis B envelope antigen status) are frequently included in the scores derived from patients with untreated CHB, whereas measurements that gauge severity of liver fibrosis and/or reserve of hepatic function (i.e., cirrhosis diagnosis, liver stiffness measurement, platelet count, or albumin) are essential components in the scores developed from treated patients. External validation is a prerequisite for clinical application but not yet performed for all scores. For the future, higher predictive accuracy may be achieved with machine learning based on more comprehensive data.

Effect of viral replication and liver fibrosis on all-cause mortality in HIV/HBV coinfected individuals: a retrospective analysis of a 15-year longitudinal cohort. Clin Infect Dis 2021; 74:1012-1021.

Abstract
BACKGROUND In individuals co-infected with HIV and hepatitis B virus (HBV), widespread tenofovir (TDF)-containing antiretroviral therapy (ART) has led to substantial decreases in HBV-DNA and HIV-RNA detection. However, the link between viral replication, liver fibrosis, and mortality remains unclear. METHODS 300 HIV-HBV co-infected individuals undergoing ART were prospectively followed. Virological and clinical data were obtained at baseline and every 6-12 months. We quantified the association between HBV-DNA, HIV-RNA, and liver fibrosis with risk of all-cause mortality using a joint longitudinal-survival model. Viral detection, viral loads, and time-averaged cumulative viral loads of HIV and HBV were modeled as three separate exposures. RESULTS During a median 10.5 years (IQR=4.0-14.6), the proportion undergoing TDF-containing ART (baseline=18.7%, end of follow-up=79.1%) and with undetectable HBV-DNA (baseline=36.7%, end of follow-up=94.8%) substantially increased. HIV-RNA was mostly undetectable during follow-up (76.6%). 42 participants died (incidence rate=1.30/100person-years, 95%CI=0.96-1.76). The leading causes of death were non-AIDS/non-liver-related malignancies (28.6%), followed by liver-related (16.7%), AIDS-related (16.7%), and other (16.7%). All-cause mortality was associated with HBV-DNA viral load (adjusted-HR per log10IU/mL=1.41, 95%CI=1.04-1.93, p=0.03) or time-averaged cumulative HBV-DNA (adjusted-HR per log10IU-years=1.37, 95%CI=1.03-1.83, p=0.03), but not undetectable HBV-DNA (adjusted-HR=0.30, 95%CI=0.08-1.09, p=0.08). Advanced liver fibrosis at baseline was also associated with increased mortality rates (adjusted-HR=2.35, 95%CI=1.16-4.76, p=0.02). No significant association between HIV-RNA replication and mortality was observed. CONCLUSIONS Concurrent and historical HBV replication and liver fibrosis are important drivers of all-cause mortality in largely TDF-treated HIV-HBV co-infected individuals, despite one-fifth of deaths being liver-related. HBV-DNA and liver fibrosis remain important prognostic indicators for this patient population.

Abstract
BACKGROUND AND AIMS Outcomes of persons with chronic hepatitis B virus (HBV) infection in the era of antiviral therapy (AVT) are not well characterized. We determined the incidence and factors associated with clinical outcomes in a multiethnic, North American cohort of adults with chronic HBV infection, who were not on AVT at enrollment. APPROACH AND RESULTS Adults with chronic HBV infection, not receiving AVT, and without a history of decompensation, HCC, or liver transplantation (LT), were prospectively followed. Participants with known human immunodeficiency virus (HIV), hepatitis C virus, or hepatitis D virus (HDV) coinfection were excluded. During follow-up, treatment could be initiated per standard of care. Clinical outcomes included: incident cirrhosis, decompensation, HCC, OLT, and HBV-related death. Among 1,418 participants analyzed, 51.5% were women, median age was 41.1 years, 75% were Asian, 10% White, 13% Black, 24% HBeAg(+), and 1.5% cirrhosis at baseline. During the study, 274 started treatment, 83 had an alanine aminotransferase flare, 118 of 330 initially HBeAg(+) became HBeAg(-), and 90 of 1,329 became HBsAg(-). After 6,641 person-years follow-up, 8 participants (4 of 21 with baseline cirrhosis) had 12 clinical outcomes (2 decompensation, 5 HCC, 2 OLT, and 3 HBV-related deaths) and 19 of 1,397 had incident cirrhosis. Twenty-one of 26 participants had first outcome before treatment, none had become HBsAg(-), whereas 5/9 HBeAg(+) had become HBeAg(-) at time of first outcome. Cumulative percentage of clinical outcomes was 16% at year 4 in participants with baseline cirrhosis and 2% (including incident cirrhosis) at year 7 in those without. CONCLUSIONS Incidence of adverse outcomes was low in this closely monitored, large cohort of North American adults with predominantly inactive, chronic HBV without cirrhosis. Our data highlight the benefits of HBsAg loss and the importance of early diagnosis and treatment to prevent cirrhosis and other complications of chronic HBV infection.

Effectiveness and Renal Safety of Tenofovir Alafenamide Fumarate among Chronic Hepatitis B Patients: Real-World Study. J Viral Hepat 2021; 28:942-950.

Abstract
Tenofovir alafenamide fumarate (TAF) has high plasma stability resulting in fewer renal adverse events compared to tenofovir disoproxil fumarate (TDF) in chronic hepatitis B (CHB) patients. We aimed to study the effectiveness and renal safety of TAF in a real-world setting, in patients with or without compromised kidney function. CHB patients (Nucleos(t)ide Analogue [NA]-naïve or experienced) who received TAF >1 year from 11 academic institutions as part of the Canadian Hepatitis B Network (CanHepB) were included. Kidney function was measured by estimated glomerular filtration rate (eGFR) as per Cockcroft-Gault. Patients were followed for up to 160 weeks. Of 176 patients receiving TAF, 143 switched from NA (88% TDF), and 33(19%) were NA naïve. Majority of NA-naïve patients (75%) achieved undetectable HBV DNA after one year of TAF treatment. Majority of patients with eGFR <60 mL/min who had renal deterioration during TDF (76%) reversed to eGFR increase after one year of TAF (p=0.009). Among patients with stage 2 chronic kidney disease (CKD) (eGFR 60-89), the estimated eGFR decline during TDF was halted after switching to TAF (p=0.09). NA-experienced patients with abnormal ALT before TAF showed a significant decline after switching to TAF: -0.005 [-0.006 - -0.004] log10 ULN U/L/month, p<0.001). In CHB patients, TAF was safe, well-tolerated and effective in this real-world cohort. Switching to TAF led to improved kidney function, particularly in those with stage 2 CKD, which suggests that the indication for TAF in the guidelines could be extended to patients with an eGFR higher than 60 mL/min.

Abstract
It is unknown how past and active hepatitis B virus (HBV) infection affect immunorecovery and mortality in people with HIV who initiate tenofovir-based antiretroviral therapy (ART). Using data collected between 2008 and 2015, we studied people with HIV in sub-Saharan Africa initiating immediate ART in the Temprano randomized control trial. We classified participants into HBV groups at ART initiation: hepatitis B surface antigen (HBsAg)-positive with HBV DNA ≥ 2,000 IU/ml; HBsAg-positive with HBV DNA < 2,000 IU/ml; isolated HBcAb-positive; resolved infection (HBsAb-positive/HBcAb-positive); and HBV non-immune/vaccinated (HBcAb-negative). We compared square-root CD4-cell count increases using mixed-effect, non-linear regression adjusted for age, sex, baseline CD4 cell count, and HIV RNA. We compared all-cause mortality using Bayesian parametric survival regression. Among 879 participants, 24 (2.7%) had HBsAg with high HBV DNA, 76 (8.6%) HBsAg with low HBV DNA, 325 (37.0%) isolated anti-HBcAb, 226 (25.7%) resolved HBV infection and 228 (25.9%) HBV non-immune/vaccinated. We found no significant difference in CD4 cell increases between HBV-infection groups after adjustment (p = 0.16). Participants with HBsAg and high HBV DNA had the highest incidence of all-cause mortality (1.9/100 person-years, 95% Credibile Interval [CrI] = 1.0-3.4). By comparison, incidence rates of mortality were reduced by 57% (95%CrI = -79%, -13%), 60% (95%CrI = -82%, -12%) and 66% (95%CrI = -84%, -23%) in those who had isolated anti-HBcAb-positive, resolved HBV infection and HBV non-immune/vaccinated, respectively. In conclusion, individuals with HIV and past HBV infection or isolated anti-HBcAb-positive serology, much like HBV non-immune/vaccinated, experience lower mortality than those with HBsAg and high HBV DNA. Additional HBV-related management would not be necessary for these individuals.

Abstract
Chronic hepatitis B infection remains a globally important cause of morbidity and mortality and has recently undergone a renaissance in therapeutic interest with increased pre-clinical and clinical testing of new drug classes. One of the first new classes in the clinic was RNA interference agents, which have the potential to impact the entire viral life cycle by reducing all virus-produced mRNA. Early clinical testing with the first of these agents in the clinic, ARC-520, demonstrated that rapid and deep reductions in viral proteins, RNA and DNA could be produced with this approach, but also the surprising insight that HBsAg production from incomplete HBV DNA integrated into the host genome appears to play a heretofore unappreciated and important role in maintaining circulating HBsAg, thought to play a fundamental role in preventing host clearance of the virus. Thus, accounting for viral DNA integration in novel HBV treatment approaches may prove to be essential to achieving successful finite therapies of this difficult to treat chronic infection.

Abstract
BACKGROUND & AIMS Tenofovir disoproxil fumarate (TDF) and entecavir are recommended as first-line treatments for chronic hepatitis B virus (HBV) infection. However, there is debate over the comparative effectiveness of these drugs in preventing hepatocellular carcinoma (HCC). We performed a systematic review and meta-analysis of the effectiveness of TDF vs entecavir in reducing the incidence of HCC among patients with chronic HBV infection. METHODS We performed a systematic review of the MEDLINE, EMBASE, Web of Science, and Cochrane Library from 2010 through 2019 for full-text articles and conference abstracts on studies of effects of TDF vs entecavir in patients with HBV infection. Extracted data were analyzed with the random-effects model. Potential sources of heterogeneity were investigated using sensitivity, meta-regression, and subgroup analyses. RESULTS Our final analysis comprised 15 studies (61,787 patients; 16,101 patients given TDF and 45,686 given entecavir). TDF treatment was associated with a significantly lower risk of HCC than entecavir (hazard ratio, 0.80; 95% CI, 0.69-0.93; P = .003; I2 = 13%). The lower risk of HCC in patients given TDF compared with entecavir persisted in sensitivity and subcohort analyses performed with propensity score-matched cohorts and cirrhosis subcohorts. Inclusion of patients with decompensated cirrhosis and the sample size were the factors with the largest effects on between-study heterogeneity in meta-regression analyses. Subsequent subgroup analyses showed no statistical differences in the incidence of death or transplantation (hazard ratio, 0.93; 95% CI, 0.73-1.17; P = .519; I2 = 6%) between patients given TDF vs entecavir. CONCLUSIONS In a meta-analysis of studies of patients with chronic HBV infection, we found that TDF treatment was associated with a significantly lower (20%) risk of HCC than entecavir treatment. Randomized trials are needed to support this finding.

Abstract
Hepatitis B virus (HBV) is a major cause of hepatocellular carcinoma (HCC). There are approximately 250 million people in the world that are chronically infected by this virus, resulting in nearly 1 million deaths every year. Many of these patients die from severe liver diseases, including HCC. HBV may induce HCC through the induction of chronic liver inflammation, which can cause oxidative stress and DNA damage. However, many studies also indicated that HBV could induce HCC via the alteration of hepatocellular physiology that may involve genetic and epigenetic changes of the host DNA, the alteration of cellular signaling pathways, and the inhibition of DNA repair mechanisms. This alteration of cellular physiology can lead to the accumulation of DNA damages and the promotion of cell cycles and predispose hepatocytes to oncogenic transformation.

Abstract
The sufficient component cause (SCC) model and counterfactual model are two common methods for causal inference, each with their own advantages: the SCC model allows the mechanistic interaction to be detailed, whereas the counterfactual model features a systemic framework for quantifying causal effects. Hence, integrating the SCC and counterfactual models may facilitate the conceptualization of causation. Based on the marginal SCC (mSCC) model, we propose a novel counterfactual mSCC framework that includes the steps of definition, identification, and estimation. We further propose a six-way effect decomposition for assessing mediation and the mechanistic interaction. The results demonstrate that when all variables are binary, the six-way decomposition is an extension of four-way decomposition and that without agonism, the six-way decomposition is reduced to four-way decomposition. To illustrate the utility of the proposed decomposition, we apply it to a Taiwanese cohort to examine the mechanism of hepatitis C virus (HCV)-induced hepatocellular carcinoma (HCC) with liver inflammation measured by alanine aminotransferase (ALT) as a mediator. Among the HCV-induced HCC cases, 62.27% are not explained by either mediation or interaction in relation to ALT; 9.32% are purely mediated by ALT; 16.53% are caused by the synergistic effect of HCV and ALT; and 9.31% are due to the mediated synergistic effect of HCV and ALT. In summary, we introduce an SCC model framework based on counterfactual theory and detail the required identification assumptions and estimation procedures; we also propose a six-way effect decomposition to unify mediation and mechanistic interaction analyses.

Abstract
Background Exposure to traffic-related pollution is positively associated with cardiovascular diseases (CVD), but little is known about how different sources of traffic pollution (eg, gasoline-powered cars, diesel-engine vehicles) contribute to CVD. Therefore, we evaluated the association between exposure to different types of engine exhaust and CVD mortality. Methods We recruited 12,098 participants from REVEAL-HBV cohort in Taiwan. The CVD mortality in 2000–2014 was ascertained by the Taiwan Death Certificates. Traffic pollution sources (2005–2013) were based on information provided by the Directorate General of Highway in 2005. Exposure to PM2.5 was based on a land-use regression model. We applied Cox proportional hazard models to assess the association of traffic vehicle exposure and CVD mortality. A causal mediation analysis was applied to evaluate the mediation effect of PM2.5 on the relationship between traffic and CVD mortality. Results A total of 382 CVD mortalities were identified from 2000 to 2014. We found participants exposed to higher volumes of small car and truck exhausts had an increased CVD mortality. The adjusted hazard ratio (HR) was 1.10 for small cars (95% confidence interval [CI], 0.94–1.27; P-value = 0.23) and 1.24 for truck (95% CI, 1.03–1.51; P-value = 0.03) per one unit increment of the logarithm scale. The findings were still robust with further adjustment for different types of vehicles. A causal mediation analysis revealed PM2.5 had an over 60% mediation effect on traffic-CVD association. Conclusions Exposure to exhaust from trucks or gasoline-powered cars is positively associated with CVD mortality, and air pollution may play a role in this association.

Lancet Gastroenterol Hepatol 2020; 6:106-119. [PMID: 33197397 PMCID: PMC7801814 DOI: 10.1016/s2468-1253(20)30307-1] [Citation(s) in RCA: 87] [Impact Index Per Article: 21.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/02/2020] [Revised: 09/08/2020] [Accepted: 09/17/2020] [Indexed: 02/06/2023]
Abstract
BACKGROUND In 2016, of the estimated 257 million people living with chronic hepatitis B virus (HBV) infection worldwide, only a small proportion was diagnosed and treated. The insufficiency of information on the proportion of people infected with HBV who are eligible for treatment limits the interpretation of global treatment coverage. We aimed to estimate the proportion of people with chronic HBV infection who were eligible for antiviral treatment worldwide, based on the WHO 2015 guidelines. METHODS In this systematic review and meta-analysis, we searched Medline, EMBASE, and the Cochrane databases from Jan 1, 2007, to Jan 31, 2018, for studies describing HBsAg-positive people in the population or health-care facilities. We extracted information from published studies using a standardised form to estimate the frequency of cirrhosis, abnormal alanine aminotransferase (ALT), HBV DNA exceeding 2000 IU/mL or 20 000 IU/mL, presence of HBeAg, and eligibility for treatment as per WHO and other guidelines as reported in the studies. We pooled proportions through meta-analysis with random effects. The study was registered with PROSPERO, CRD42020132345. FINDINGS Of the 13 497 studies, 162 were eligible and included in our analysis. These studies included 145 789 participants. The pooled estimate of the proportion of cirrhosis was 9% (95% CI 8-10), ranging from 6% (4-8) in community settings to 10% (9-11) in clinic settings. Examining the proportion of participants who had characteristics used to determine eligibility in the WHO guidelines, 1750 (10·1%) of 17 394 had HBV DNA exceeding 20 000 IU/mL, and 20 425 (30·8%) of 66 235 had ALT above the upper limit of normal. 32 studies reported eligibility for treatment according to WHO or any other guidelines, with a pooled estimate of eligibility at 19% (95% CI 18-20), ranging from 12% (6-18) for studies in community settings to 25% (19-30) in clinic settings. INTERPRETATION Many studies described people with HBV infection, but few reported information in a way that allowed assessment of eligibility for treatment. Although about one in ten of the 257 million people with HBV infection (26 million) might be in urgent need of treatment because of cirrhosis, a larger proportion (12-25%) is eligible for treatment in accordance with different guidelines. Future studies describing people with HBV infection should report on treatment eligibility, according to broadly agreed definitions. FUNDING WHO and US Centers for Disease Control and Prevention.

Abstract
Over 257 million individuals worldwide are chronically infected with the Hepatitis B Virus (HBV). Nucleos(t)ide analogues (NAs) are the first-line treatment option for most patients. Entecavir (ETV) and tenofovir disoproxil fumarate (TDF) are both potent, safe antiviral agents, have a high barrier to resistance, and are now off patent. They effectively suppress HBV replication to reduce the risk of cirrhosis, liver failure, and hepatocellular carcinoma (HCC). Treatment is continued long-term in most patients, as NA therapy rarely induces HBsAg loss or functional cure. Two diverging paradigms in the treatment of chronic hepatitis B have recently emerged. First, the public health focussed "treat-all" strategy, advocating for early and lifelong antiviral therapy to minimise the risk of HCC as well as the risk of HBV transmission. In LMICs, this strategy may be cost saving compared to monitoring off treatment. Second, the concept of "stopping" NA therapy in patients with HBeAg-negative disease after long-term viral suppression, a personalised treatment strategy aiming for long-term immune control and even HBsAg loss off treatment. In this manuscript, we will briefly review the current standard of care approach to the management of hepatitis B, before discussing emerging evidence to support both the "treat-all" strategy, as well as the "stop" strategy, and how they may both have a role in the management of patients with chronic hepatitis B.

Zhou K, Dodge JL, Grab J, Poltavskiy E, Terrault NA. Mortality in adults with chronic hepatitis B infection in the United States: a population-based study. Aliment Pharmacol Ther 2020; 52:382-389. [PMID: 32432816 PMCID: PMC7935406 DOI: 10.1111/apt.15803] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/31/2019] [Revised: 03/05/2020] [Accepted: 04/29/2020] [Indexed: 02/06/2023]
Abstract
BACKGROUND Chronic hepatitis B infection is an important contributor to mortality in the United States, yet impact of available and effective oral antivirals on mortality among infected individuals is unknown. AIMS To compare risks and predictors of mortality in a recent time period between those with chronic, prior and no hepatitis B infection. METHODS This is a population-based cohort study of National Health and Nutrition Examination Surveys participants between 1999 and 2014 linked to National Death Index data. Adults aged 20 years or older with hepatitis B serologic testing were included. Outcomes of all-cause and liver-related mortality were evaluated using Cox regression. RESULTS Of 39 206 participants, 192 (0.5%) had chronic and 2694 (6.9%) had prior hepatitis B infection. The all-cause age/sex-standardised mortality rates for chronic, prior and uninfected were 21.4, 15.1 and 11.8 per 1000 person-years respectively. Liver-related mortality occurred at respective rates of 4.1, 0.3 and 0.1 per 1000 person-years. In multivariable analyses, those with chronic infection had 1.9-fold (95% CI 1.1-3.3) increased hazard of all-cause mortality and 13.3-fold (95% CI 3.9-45.5) increased hazard of liver-related mortality compared to uninfected. Predictors of all-cause mortality among chronic infection included heavy alcohol use (HR 18.3, 95% CI 3.3-100.6) and higher alanine aminotransferase (HR 1.02, 95% CI 1.00-1.03). CONCLUSIONS Mortality among adults living with chronic hepatitis B infection still exceeds that of uninfected despite availability of improved therapeutics. Identification of chronic infection, initiation of treatment among eligible and modulation of co-factors for disease progression are needed to improve survival.

Abstract
Hepatitis B virus (HBV) infection is the most common chronic viral infection worldwide and remains a significant global health problem. Chronic HBV infection can progress to cirrhosis, liver failure, and hepatocellular carcinoma. Outcome of chronic HBV infections depends on the host, virus, and environmental factors. Although effective prophylactic vaccines and antiviral therapies exist, curative treatment is not yet available. Intense research into a cure for HBV is ongoing and proposed definitions of cure and endpoints for clinical trials evaluating "curative" therapy are discussed.

Abstract
AIMS To evaluate the efficacy and safety of 144-week tenofovir disoproxil fumarate (TDF) therapy in treatment-naïve chronic hepatitis B (CHB) patients in Korean. METHODS In total, 579 treatment-naïve CHB patients at 11 medical centers were enrolled retrospective and prospective from September 2015 to January 2016 by design (NCT02533544). We evaluated the complete virologic response (CVR) rate and the renal safety of TDF. RESULTS The overall CVR rate was 69.4%, 87.0%, and 89.7% at weeks 48, 96, and 144, respectively. In the HBeAg-positive CHB patients, the CVR rate at weeks 48, 96, and 144 was 61.4%, 83.1%, and 89.6%, respectively. The rates of HBeAg loss and seroconversion at weeks 48, 96, and 144 were 16.6%, 23.5%, 34.1%, and 7.6%, 8.9%, 13.3%, respectively. In HBeAg-negative CHB patients, the CVR rate at weeks 48, 96, and 144 was 82.5%, 93.2%, and 90.0%, respectively. The rate of alanine aminotransferase normalization was 36.9%, 45.4%, and 46.8% at weeks 48, 96, and 144, respectively. Of the CHB patients, 0.9% showed an elevated creatinine (> 0.5 mg/dL from baseline). Age (≥ 60 years) was significantly associated with a decline in renal function at week 144 (P < 0.0001). Comorbidities (diabetes or hypertension) showed the tendency to reduce renal function (P = 0.0624). Hepatocellular carcinoma developed in 10 (1.7%) patients and was related to cirrhosis. CONCLUSIONS TDF therapy induced sustained viral suppression and had a favorable safety profile over a 3-year period. However, close monitoring of renal function should be mandatory in treating CHB patients receiving TDF, particularly older patients.

Abstract
OBJECTIVES Chronic hepatitis B (CHB) can progress into liver fibrosis and cirrhosis with poor outcomes. Early and accurate diagnosis of liver fibrosis/cirrhosis is important to guide the preventive strategy of their related complications. METHODS A Chinese multicenter cross-sectional study was conducted to develop and validate a novel noninvasive program for staging liver fibrosis in untreated patients with CHB. Liver histology was evaluated independently by 2 pathologists. The alanine aminotransferase ratio, Hepascore, and aspartate aminotransferase to platelet index values were calculated. Liver stiffness measurement (LSM) and diameter of the spleen were measured. Logistic regression with ℓ1 penalty of regression coefficients was used to select the optimal predictors. The diagnostic accuracy for the stage of liver fibrosis was assessed by the area under the receiver operator characteristic curve with 95% confidence interval (CI). RESULTS A total of 1,200 patients with CHB were included, of whom 800 and 400 were in training and validation sets, respectively. LSM, platelets, age, hyaluronic acid, and diameter of the spleen were the top 5 predictors associated with any stage of liver fibrosis and integrated into a novel noninvasive program, named as the Chin-CHB score. The area under the receiver operator characteristic curve of the Chin-CHB score was 0.893 (95% CI: 0.77-0.92) for diagnosing significant fibrosis, 0.897 (95% CI: 0.85-0.95) for advanced fibrosis, and 0.909 (95% CI: 0.87-0.95) for cirrhosis. The diagnostic performance of the Chin-CHB score was similar between training and validation sets. The Chin-CHB score had better diagnostic performance than aspartate aminotransferase to platelet index, alanine aminotransferase ratio, LSM alone, and Hepascore for diagnosing any stage of liver fibrosis. CONCLUSIONS The Chin-CHB score had good diagnostic performance for any stage of liver fibrosis.

Abstract
OBJECTIVES Chronic hepatitis B virus (HBV) infection is associated with a higher risk of liver diseases. Substantial uncertainty remains, however, about the associations of HBV infection with mortality from extrahepatic causes, especially from subtypes of cardiovascular diseases. We prospectively examined the association of chronic HBV infection with total and cause-specific mortality. DESIGN Population-based prospective cohort study. SETTING China Kadoorie Biobank in which participants from 10 geographically diverse areas across China were enrolled between 2004 and 2008. PARTICIPANTS 475 801 participants 30-79 years of age without reporting major chronic diseases at baseline were enrolled. Hepatitis B surface antigen (HBsAg) was tested using an on-site rapid test strip at baseline. PRIMARY AND SECONDARY OUTCOME MEASURES Total and cause-specific mortality. RESULTS A total of 35 822 deaths were recorded during ~10 years of follow-up. In multivariable-adjusted analyses, compared with HBsAg-negative participants, HBsAg-positive participants had an increased risk of total mortality (HR=2.01, 95% CI: 1.91 to 2.12), which was higher in men (HR=2.16, 95% CI: 2.01 to 2.31) than in women (HR=1.74, 95% CI: 1.60 to 1.90). Presence of HBsAg was associated with increased mortality from liver cancer (1339 deaths, HR=13.95, 95% CI: 12.46 to 15.62), infections (410 deaths, HR=10.30, 95% CI: 8.21 to 12.94), digestive diseases (688 deaths, HR=6.83, 95% CI: 5.49 to 8.50), intracerebral haemorrhage (4077 deaths, HR=1.38, 95% CI: 1.14 to 1.68) and ischaemic heart diseases (4624 deaths, HR=1.31, 95% CI: 1.09 to 1.58). The positive association between HBsAg status and risk of death was stronger in participants younger than 50 years, smokers, physically active or non-hypertensive participants. CONCLUSIONS Among Chinese adults, chronic HBV infection was associated with increased mortality from a range of hepatic and extrahepatic diseases.

Abstract
OBJECTIVES There is limited data on the effect of antiviral therapies on clinical outcomes in HIV and hepatitis B virus (HBV)-infected individuals in sub-Saharan Africa. DESIGN Single center, prospective longitudinal cohort study at Management and Development for Health supported HIV Care and Treatment clinics in Dar es Salaam, Tanzania. METHODS Between April 2014 and December 2015, HIV-infected, HBV-infected and HIV/HBV-coinfected, treatment naïve, Tanzanian adults more than 18 years of age were eligible for enrollment and followed for 10-18 months after initiating antivirals. All HIV-infected and HIV/HBV-coinfected participants received tenofovir, lamivudine and efavirenz; HBV-infected participants received lamivudine. Multivariate regression models were constructed to identify factors associated with mortality in HIV-infected and HIV/HBV-coinfected participants. RESULTS A total of 265 HIV-infected, 165 HBV-infected and 64 HIV/HBV-coinfected participants were analyzed. At baseline, HBV-infected participants were younger and had a higher BMI than HIV-infected and HIV/HBV-coinfected participants. After a median of 371 (interquartile range 50) days on treatment, there were 40 deaths. Mortality was significantly higher among HIV/HBV-coinfected participants compared with HIV and HBV-infected participants [HIV/HBV-coinfected 12 of 64 (19%) vs. HIV-infected 26 of 265 (10%) and HBV-infected two of 265 (1%), P < 0.01]. High baseline HIV RNA and low hemoglobin levels, but not HBV coinfection were independently associated with early mortality in multivariate analyses of HIV-infected participants. CONCLUSION High rates of early mortality were observed after treatment initiation in HIV/HBV-coinfected individuals compared with participants with HIV or HBV alone, despite robust aspartate aminotransferase to platelet ratio index declines and high rates of virologic suppression. HIV rather than HBV-related factors are more important contributors to mortality in these individuals.

Abstract
BACKGROUND The serum alanine aminotransferase (ALT) level has been used to identify at-risk patients with chronic hepatitis B (CHB) who need antiviral therapy. However, the level associated with increased liver-related mortality requiring active treatment is still unclear. METHODS We used a Health Examination Cohort of the National Health Insurance Service of Korea that included approximately 0.5 million individuals aged 40-79 years. In total, 12 486 patients with CHB and no other concurrent liver disease were enrolled, and patients' liver-related mortality, including that owing to liver cancer, was investigated over 9 years. RESULTS The serum ALT level was correlated positively with liver-related mortality. The rates in men were 0.14, 0.17, 0.24, 0.57, 0.63 and 0.85 per 100 person-years (%) for serum ALT levels of <20, 20-29, 30-39, 40-49, 50-79 and ≥80 U/L, respectively, and the corresponding liver-related mortality rates in women were 0.03%, 0.09%, 0.12%, 0.63%, 0.65% and 0.32%. In patients with ALT levels of 40-79 U/L, the liver-related mortality rates were 0.60% in men and 0.64% in women, which were similar to the overall mortality rate of age- and sex-matched subjects without CHB (0.69%). The best cut-off values for liver-related mortality prediction were >34 U/L in men and >30 U/L in women. CONCLUSIONS The liver-related mortality rate increased significantly, even in CHB patients with relatively low serum ALT levels. Careful monitoring or earlier antiviral therapy should be considered for patients aged >40 years with serum ALT levels above the upper limit of normal.

Abstract
OBJECTIVE Liver biopsy is the gold standard test for assessment of liver pathology. This study was performed to assess the predictive value of spleen thickness for liver pathology and the role of routine follow-up procedures in significant liver pathology for patients with chronic hepatitis B (CHB) with persistently normal alanine aminotransferase (PNALT) or minimally raised alanine aminotransferase (ALT). METHODS Patients with CHB who underwent percutaneous liver biopsy were retrospectively reviewed. The relationship of liver pathology with age, ALT, hepatitis B e-antigen, and spleen thickness was statistically analyzed, and the predictive accuracy of spleen thickness was evaluated. RESULTS In total, 80.65% of patients had significant necroinflammation and/or fibrosis. Nearly 60% of patients had splenomegaly, of which 89.12% had a histopathological grade of ≥G2 and/or S2. Spleen thickness was predictive of liver pathology, and significant histological findings increased as the hepatitis B virus (HBV) DNA level increased. CONCLUSIONS Spleen thickness is an effective predictor of liver pathology in patients with PNALT or minimally raised ALT. Additionally, the prevalence of significant histological findings tended to increase as the HBV DNA level increased. Patients with CHB and splenomegaly and a high HBV DNA level should be treated early with antivirals to improve liver pathology.

Interferon-based treatment is superior to nucleos(t)ide analog in reducing HBV-related hepatocellular carcinoma for chronic hepatitis B patients at high risk. Expert Opin Biol Ther 2018; 18:1085-1094.

Abstract
BACKGROUND The effect of nucleos(t)ide analogs (NAs) versus interferon (IFN) on the occurrence of hepatocellular carcinoma (HCC) in chronic hepatitis B (CHB) is controversial. We assessed whether antiviral strategy affected HCC development in CHB patients at different HCC risks. METHODS 1112 CHB patients with antiviral therapy were included in this retrospective study. Patients treated with NAs only were classified into NAs group (n = 682) while those received IFN treatment with or without NAs were defined as IFN group (n = 430). Propensity score matching (PSM) was applied to minimize baseline differences. RESULTS Totally, 31 patients developed HCC during follow-up (median 5.41 years). The cumulative HCC incidence at 10 years was significantly lower in the IFN group than NAs group (2.7% vs 8.0%, p < 0.001). Similar results were obtained in the PSM-cohort. Patients with IFN-based treatment were less likely to develop HCC than those with NAs (Hazard ratio = 0.15; 95% CI 0.04-0.66; p = 0.012). Subgroup analyses demonstrated that this superiority of IFN in reducing HCC development was obvious in patients at high- but not low-risk of HCC. CONCLUSIONS Reduction of HCC development was more significant in CHB patients at higher HCC risk with IFN-based therapy than NAs treatment.

Abstract
Background The impact of different anti-virus regimens on prognosis of Chronic hepatitis B (CHB) related cirrhosis remains to be explored. We aim to investigate whether CHB-related HCC patients receiving nucleoside analogue regimen or not have a different prognosis. Methods Two hundred forty-two CHB-related compensated cirrhosis patients were attributed into groups regarding their anti-virus regimens containing tenofovir disoproxil fumarate (TDF) or not. The results of two groups were reviewed and investigated. The probability of hepatocellular carcinoma (HCC) development among each group were analyzed and compared. Results Two hundred forty-two CHB-related compensated cirrhosis patients from 2008 June to 2011 December were included in our study. One hundred twenty-seven patients received anti-virus regimen containing TDF and 115 patients received anti-virus regimen without TDF. Child-Pugh score, alanine aminotransferase (ALT), total bilirubin level, status of hepatitis B e antigen (HBeAg) and serum HBV DNA level were compared between groups. The cumulative probability of HCC development in TDF-contained group were significantly lower than it in non-TDF-contained group (p < 0.05). Multi-variant analysis indicated that TDF-containing regimen treatment was significantly associated with lower probability of HCC development, (hazard ratio, 0.18; 95% confidence interval range, 0.07-0.45, p < 0.05). Conclusion Anti-virus regimen containing TDF benefits for the prognosis of CHB-related liver cirrhosis patients.

Abstract
Background Tenofovir disoproxil fumarate (TDF) and entecavir (ETV) are recommended as the first-line choices regarding the treatment of chronic hepatits B. The impact of the two antiviral agents on prognosis of Chronic hepatitis B (CHB) related hepatocellular carcinoma (HCC) remains to be explored. We aim to investigate whether CHB-related HCC patients receiving TDF and ETV have a different prognosis. Methods 233 CHB-related compensated cirrhosis patients were divided into groups according to the nucleut(s)ide patients received. The results of TDF and ETV groups were reviewed and compared. The disease-free survival (DFS) and overall survival (OS) of both groups were analyzed and compared. Results 233 CHB-related compensated cirrhosis patients from 2013 October to 2014 November were included in our study. 107 and 126 patients received TDF and ETV monotherapy, respectively. Child-Pugh score, alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin level, status of hepatitis B e antigen (HBeAg) and serum HBV DNA level were compared between groups. DFS in TDF-treatment group were significantly longer than it in ETV-treatment group (p < 0.05). multi-variant analysis indicated that TDF duration was significantly associated with lower probability of HCC development, (hazard ratio, 0.35; 95% confidence interval range, 0.33–0.84, p < 0.05). Conclusion Anti-virus regimen containing TDF benefits for the prognosis of CHB-related liver cirrhosis patients.

Fibrosis-4 index predicts cirrhosis risk and liver-related mortality in 2075 patients with chronic HBV infection. Aliment Pharmacol Ther 2018; 47:1480-1489. [PMID: 29601647 DOI: 10.1111/apt.14619] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/05/2018] [Revised: 01/26/2018] [Accepted: 02/28/2018] [Indexed: 12/14/2022]
Abstract
BACKGROUND Fibrosis-4 index (FIB-4) is a surrogate marker for hepatic fibrosis in hepatitis B virus (HBV) carriers. AIM To investigate whether FIB-4 index stratifies the risks of adverse liver events. METHODS A total of 2075 treatment-naïve, noncirrhotic the patients with chronic HBV infection were included. Most of them (82.1%) were HBeAg-negative patients and their baseline FIB-4 levels were explored to stratify the risks of cirrhosis, cirrhosis-related complications and liver-related mortality. RESULTS During a mean follow-up period of 15.47 years, we found a higher baseline FIB-4 index was associated with increased incidence rates of cirrhosis in addition to the common host and viral factors. Patients with FIB-4 >1.29, compared to those with FIB-4 <1.29, were associated with increased risks of cirrhosis, cirrhosis-related complications and liver-related mortality with the hazard ratio (95% confidence interval) of 6.19 (4.76-8.05), 6.88, (3.68-12.86) and 7.79, (4.54-13.37) respectively. Within the first 3 years of follow-up, FIB-4 remained stable and its kinetics were consistently associated with the develoopment of adverse liver events. Furthermore, FIB-4 index of 1.29 was able to stratify all the risks of adverse liver events even in HBeAg-negative patients with a low risk of disease progression (HBV DNA <2000 IU/mL, HBsAg <1000 IU/mL and ALT <40 U/L). Only 1 patient with FIB-4 index <1.29 developed cirrhosis but not other events within 15 years of follow-up. CONCLUSIONS In noncirrhotic patients with chronic HBV infection, a higher FIB-4 index was associated with increased risks of adverse liver events. FIB-4 index <1.29 is useful for the prediction of the lowest risks of disease progression.
