Introduction: Several non-invasive tests (NIT) have been reported for predicting liver fibrosis to avoid percutaneous liver biopsy (PLB)., Aim: To evaluate the performance of NIT in Tunisian patients with chronic hepatitis B (CHB)., Methods: We calculated the ASAT/platelet ratio index (APRI), GGT-to-platelet ratio (GPR), Fibrosis-4 score (FIB-4), and RDW/platelet ratio (RPR). The accuracy of NIT was compared with the Metavir score for the detection of liver fibrosis stage using the area under the ROC curves (AUROC)., Results: Seventy-seven CHB patients were included. For predicting significant fibrosis, the AUROC of GPR (0.81; CI95% [0.68-0.93]; P < 0.001) was significantly higher than that of RPR (0.67; CI95% [0.52-0.82]; P = 0.03) and FIB-4 (0.746; CI95% [0.61-0.88]; P = 0.002), but was similar to APRI (0.88; CI95% [0.79-0.97]; P < 0.001). For advanced fibrosis, the AUROC of GPR (0.93; CI95% [0.84-1]; P < 0.001) was higher than that of RPR (0.83; CI95% [0.69-0.97]; P < 0.001) and FIB-4 (0.88; CI95% [0.76-0.99]; P < 0.001), but similar to APRI (0.93; CI95% [0.87-0.99]; P < 0.001). For predicting cirrhosis, the AUROC of GPR (0.98; CI95% [0.95-1]; P < 0.001) was higher than that of APRI (0.95; CI95% [0.90-1]; P = 0.02), similar to RPR (0.99; CI95% [0.98-1]; P < 0.001) but lower than that of FIB-4 (1; CI95% [1-1]; P < 0.001). In multivariate analysis, APRI (OR = 3.78; P = 0.002) and FIB-4 (OR = 2.65; P = 0.01) were independent predictors of significant fibrosis. GPR was the only independent predictor of advanced fibrosis (OR = 4.64; P = 0.001) and FIB-4 was the independent predictor of cirrhosis (OR = 2.85; P < 0.001)., Conclusion: GPR does not demonstrate significant advantages over APRI, FIB-4, and RPR in identifying liver fibrosis in patients with chronic hepatitis B (CHB).

Background and Aims: This study evaluates the cost burdens of inpatient care for chronic hepatitis B (CHB). We aimed to stratify the patients based on the presence of cirrhosis and conduct subgroup analyses on patient demographics and medical characteristics., Methods: The 2016-2019 National Inpatient Sample was used to select individuals diagnosed with CHB. The weighted charge estimates were derived and converted to admission costs, adjusting for inflation to the year 2016, and presented in United States Dollars. These adjusted values were stratified using select patient variables. To assess the goodness-of-fit for each trend, we graphed the data across the respective years, expressed in a chronological sequence with format (R 2 , p-value). Analysis of CHB patients was carried out in three groups: the composite CHB population, the subset of patients with cirrhosis, and the subset of patients without cirrhosis., Results: From 2016 to 2019, the total costs of hospitalizations in CHB patients were $603.82, $737.92, $758.29, and $809.01 million dollars from 2016 to 2019, respectively. We did not observe significant cost trends in the composite CHB population or in the cirrhosis and non-cirrhosis cohorts. However, we did find rising costs associated with age older than 65 (0.97, 0.02), white race (0.98, 0.01), Hispanic ethnicity (1.00, 0.001), and Medicare coverage (0.95, 0.02), the significance of which persisted regardless of the presence of cirrhosis. Additionally, inpatients without cirrhosis who had comorbid metabolic dysfunction-associated steatotic liver disease (MASLD) were also observed to have rising costs (0.96, 0.02)., Conclusions: We did not find a significant increase in overall costs with CHB inpatients, regardless of the presence of cirrhosis. However, certain groups are more susceptible to escalating costs. Therefore, increased screening and nuanced vaccination planning must be optimized in order to prevent and mitigate these growing cost burdens on vulnerable populations., (© 2024.

As a hepatotropic virus, hepatitis B virus (HBV) can establish a persistent chronic infection in the liver, termed, chronic hepatitis B (CHB), which causes a series of liver-related complications, including fibrosis, cirrhosis, and hepatocellular carcinoma (HCC). HCC with HBV infection has a significantly increased morbidity and mortality, whereas it could be preventable. The current goal of antiviral therapy for HBV infection is to decrease CHB-related morbidity and mortality, and achieve sustained suppression of virus replication, which is known as a functional or immunological cure. The natural history of chronic HBV infection includes four immune phases: the immune-tolerant phase, immune-active phase, inactive phase, and reactivation phase. However, many CHB patients do not fit into any of these defined phases and are regarded as indeterminate. A large proportion of indeterminate patients are only treated with dynamic monitoring rather than recommended antiviral therapy, mainly due to the lack of definite guidelines. However, many of these patients may gradually have significant liver histopathological changes during disease progression. Recent studies have focused on the prevalence, progression, and carcinogenicity of indeterminate CHB, and more attention has been given to the prevention, detection, and treatment for these patients. Herein, we discuss the latest understanding of the epidemiology, clinical characteristics, and therapeutic strategies of indeterminate CHB, to provide avenues for the management of these patients., (© 2024.

Patients with chronic liver disease (CLD) experience health-related quality of life (HRQoL) and patient-reported outcomes (PROs) impairments. We assessed and identified predictors of HRQoL and PROs in CLD patients from Saudi Arabia (SA), Turkey and Egypt. Patients enrolled in Global Liver Registry™ with chronic hepatitis B (CHB), chronic hepatitis C (CHC) and non-alcoholic fatty liver disease (NAFLD) or non-alcoholic steatohepatitis (NASH) were included. Clinical data and PRO questionnaires (FACIT-F, CLDQ and WPAI) were compared across countries. Linear regression identified PRO predictors. Of the 4014 included patients, 26.9% had CHB, 26.9% CHC and 46.1% NAFLD/NASH; 19.2% advanced fibrosis. Compared across countries, CHB patients were younger in Egypt (mean age [years] 41.2 ± 11.4 vs. 45.0 ± 10.3 SA, 46.1 ± 12.0 Turkey), most often employed in SA (64.8% vs. 53.2% Turkey) and had the lowest prevalence of obesity in Turkey (26.7% vs. 37.8% SA, 38.5% Egypt). In SA, CHB patients had lowest prevalence of fibrosis and comorbidities (all p < .01). There was a higher frequency of males with NAFLD/NASH in SA (70.0% vs. 49.6% Turkey, and 35.5% Egypt). Among NAFLD/NASH patients, CLDQ-NAFLD/NASH scores were highest in SA (mean total score: 5.3 ± 1.2 vs. 4.8 ± 1.2 Turkey, 4.1 ± 0.9 Egypt, p < .01). Independent predictors of worse PROs included younger age, female sex, advanced fibrosis, non-hepatic comorbidities and lack of regular exercise (all p < .05). Clinical presentation and PRO scores of CLD patients vary across SA, Turkey and Egypt. Impairment of HRQoL is associated with demographic factors, lack of regular exercise, advanced fibrosis and non-hepatic comorbidities., (© 2024 John Wiley & Sons Ltd.)

Background & Aims: The impact of metabolic dysfunction-associated steatotic liver disease (MASLD) on the development of cirrhosis and hepatocellular carcinoma (HCC) by chronic hepatitis B (CHB) or C infection and antiviral treatment statuses is not well-known., Methods: A total of 336,866 adults aged ≥30 years were prospectively enrolled in a health screening program between 1997-2013. MASLD was identified by abdominal ultrasonography and cardiometabolic profiles. Data linkage was performed using 3 nationwide databases-National Health Insurance, Cancer Registry, and Death Certification System-to obtain information on antiviral treatment, vital status, and newly diagnosed cirrhosis and HCC. Follow-up was conducted until December 31, 2019., Results: In the total population, 122,669 (36.4%) had MASLD. Over a mean follow-up of 15 years, 5562 new cases of cirrhosis and 2273 new cases of HCC were diagnosed. Although MASLD significantly increased the cumulative risks of cirrhosis or HCC (P < .0001), the associated risk was more pronounced when comparing CHB or C infection with the presence of MASLD. Stratifying the participants based on their MASLD and CHB or C statuses, hazard ratios (HR adj ) with 95% confidence intervals for HCC were 8.81 (7.83-9.92) for non-steatotic liver disease (SLD) with CHB or C, 1.52 (1.32-1.74) for MASLD without CHB or C, and 8.86 (7.76-10.12) for MASLD with CHB or C, compared with non-SLD without CHB or C (all P < .0001). Among CHB or C patients who received antivirals during follow-up, MASLD was associated with increased risks of cirrhosis and HCC, with HR adj of 1.23 (1.01-1.49) and 1.32 (1.05-1.65), respectively., Conclusions: These findings underscore the need to prioritize treatment of chronic viral hepatitis before addressing MASLD., (Copyright © 2024 AGA Institute.

Introduction: Due to hepatitis B virus (HBV) treatment and vaccination during the last decades in Spain, epidemiological and prognosis of chronic hepatitis B (CHB) may have changed., Methods: Retrospective review of CHB-HIV coinfected patients in a single reference center in Madrid until year 2019. We compared incidence, epidemiological and clinical characteristics according diagnosis period (before 2000, 2000-2004, 2005-2009, 2010-2014, 2015-2019). A retrospective longitudinal study was done to assess mortality, related risk factors and hepatic decompensation., Results: Out of 5452 PLHIV, 160 had CHB (prevalence 2.92%; 95%CI 2.5-3.4), 85.6% were men, median age 32.1 (27-37.2). Incidence rate did not change over the years (2.4/100 patients-year). PLHIV with CHB diagnosed before year 2000 (n = 87) compared with those diagnosed between 2015 and 2019 (n = 11) were more often native-Spanish (90.8% vs. 18.2%), had infected using intravenous drugs (55.2% vs. 0), were coinfected with hepatitis C (40% vs. 9.1%) or hepatitis delta virus (30.4% vs. 0) and had more severe liver disease (cirrhosis 24.1% vs. 0). After a median follow-up of 20.4 years, 23 patients died (7.1/1000 patients-year) and 19 had liver decompensation (4.9/1000 patients-year). All deaths and liver decompensation occurred in patients diagnosed before year 2010. Mortality was associated with higher liver fibrosis in Fibroscan® (HR 1.06, 95% CI 1.03-1.09)., Conclusion: The epidemiology of CHB in PLHIV in our cohort is changing with less native Spanish, more sexually transmitted cases and less coinfection with other hepatotropic virus. Patients diagnosed before 2010 have worst prognosis related to higher grades of liver fibrosis., (Copyright © 2022 Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica.

Background: Serum aspartate aminotransferase (AST) to alanine aminotransferase (ALT) ratio (AAR) is one of the most frequent indicators to discriminate fibrosis and cirrhosis. However, the results remained controversial. The aim of this study was to evaluate the predictive effect of AAR on hepatitis B virus (HBV)-related cirrhosis development., Method: A retrospective cohort study was conducted based on 1754 chronic HBV-infected patients. Clinical variables at their initial visit and follow-up data were collected. Cox proportional hazards model was constructed to evaluate the predictive value of AAR on cirrhosis risk, and its discrimination accuracy was determined by receiver operating characteristic (ROC). The time-dependent effect was assessed by a Fine and Gray competing risk model., Results: Compared to patients with lower AAR, those with elevated AAR level had higher risk of cirrhosis development by adjusting for host characteristics (dichotomized analyses: hazard ratio = 2.77, P = 8.25 × 10 -4 ; tertile analyses: hazard ratio = 2.95, P = 1.61 × 10 -3 ), with an increasing risk trend ( Ptrend = 4.56 × 10 -4 ). The effect remained prominent when ALT or AST was abnormal, while no significant risk was observed when AST and ALT were simultaneously normal. Time-dependent effect analysis demonstrated a persistently higher risk, with the average hazard ratio equivalent to 1.92. AAR level could improve the discrimination efficacy of host variables with area under the curve increased from 0.684 to 0.711 ( P  =  0.039 )., Conclusion: Higher AAR was significantly associated with increased risk of HBV-related cirrhosis, and might be a potential predictor of cirrhosis development., (Copyright © 2024 The Author(s).

Background: Chronic hepatitis B (CHB) is well-known as a major risk for liver cirrhosis and hepatocellular carcinoma (HCC). The A1762T/G1764A double mutation in the hepatitis B virus genome affects the production of HBe antigen and is established as a predictive marker for progression to HCC. Thus, this study aimed to investigate the prevalence and clinical significance of the mutation in Thai CHB patients., Methods:  A cross-sectional study was conducted in 78 Thai CHB patients who were assessed for hepatitis B profiles, HBsAg, HBeAg and anti-HBeAg, transaminitis, liver fibrosis defined by FIB-4 (FIB-4) score and AST to platelet ratio index (APRI), alpha-fetoprotein (AFP) and active hepatitis B status. HBV A1762T/G1764A mutation was examined by SYBR Green I Real-time PCR. Chi-square and Mann-Whiney U tests were performed to determine the association between the mutation and variables., Results: The prevalence of patients infected with the A1762T/G1764A mutation was 44.9%. The mutation was associated with HBeAg status (p=0.027) and HBsAg levels (p=0.008), transaminitis (p=0.011), and active hepatitis B (p=0.037), but not liver fibrosis markers, FIB-4 score and APRI, and AFP. Binary logistic regression identified the mutation as a predictive factor of active hepatitis B (OR 3.5, 95%CI, 1.1-11.3, p=0.037). Patients infected with the mutant exhibited significantly higher levels of HBsAg (p=0.011) and HBV viral load (p=0.047), but lower levels of HBeAg (p=0.12) than those infected with the wild-type HBV., Conclusion: The data indicate the high prevalence of the A1762T/G1764A mutation and its significant association with the severity of Thai CHB patients and the HBV mutation is proposed as a predictive marker of active hepatitis B status in CHB patients.

Background: China bears a high burden of both hepatitis B virus (HBV) infection and type 2 diabetes mellitus (T2DM). T2DM accelerates the progression of liver disease among individuals infected with HBV. This study aims to assess the excess disease burden caused by comorbid T2DM among HBV-infected individuals in China., Methods: We estimated the disease burden of HBV and its complications in China from 2006 to 2030 using individual-based Markov models. The baseline population consisted of 93 million HBV-infected individuals derived from the 2006 National Serological Epidemiological Survey. We developed two models: one incorporated the impact of T2DM on the disease progression of HBV infection, while the other did not consider the impact of T2DM. By comparing the outcomes between these two models, we estimated the excess disease burden attributable to comorbid T2DM among HBV-infected individuals., Results: The incidence of severe HBV complications, including cirrhosis, hepatocellular carcinoma (HCC), and liver-related deaths, exhibited an increasing trend from 2006 to 2030 among the Chinese HBV-infected population. Comorbid T2DM increased the annual incidence and cumulative cases of severe HBV complications. From 2006 to 2022, comorbid T2DM caused 791,000 (11.41%), 244,000 (9.27%), 377,000 (8.78%), and 796,000 (12.19%) excess cases of compensated cirrhosis, decompensated cirrhosis, HCC, and liver-related deaths, respectively. From 2023 to 2030, comorbid T2DM is projected to result in an 8.69% excess in severe HBV complications and an 8.95% increase in liver-related deaths. Among individuals aged 60 and older at baseline, comorbid T2DM led to a 21.68% excess in severe HBV complications and a 28.70% increase in liver-related deaths from 2006 to 2022, with projections indicating a further 20.76% increase in severe HBV complications and an 18.31% rise in liver-related deaths over the next seven years., Conclusions: Comorbid T2DM imposes a substantial disease burden on individuals with HBV infection in China. Healthcare providers and health policymakers should develop and implement tailored strategies for the effective management and control of T2DM in individuals with HBV infection., (© 2024.

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 >10 6 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., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Background/purpose: In 2020, metabolic Associated Fatty Liver Disease (MAFLD) was proposed to replace non-alcoholic fatty liver disease (NAFLD) with new diagnostic criteria. The prevalence and clinical outcomes of MAFLD subtypes remained unclear., Methods: The participants from Taiwan bio-bank cohort were included. MAFLD was defined as the presence of fatty liver, plus any of the following three conditions: overweight/obesity, diabetes mellitus (DM), or metabolic dysfunction. The patients with positive HBsAg or anti-HCV were considered as chronic HBV or HCV infection. NAFLD fibrosis score (NFS) > 0.676 plus fibrosis 4 (FIB-4) score > 2.67 was defined as advanced liver fibrosis. Atherosclerosis was diagnosed as having carotid plaques on duplex ultrasounds. The clinical outcomes were assessed among four subtypes of MAFLD including DM, obesity, chronic HBV infection, and chronic HCV infection., Results: A total of 21,885 participants (mean age 55.34 ± 10.31; 35.69% males) were included in the final analysis. Among them, 38.83% were diagnosed with MAFLD. The prevalence of MAFLD was 66.95% in DM patients, 65.07% in obese participants, 33.74% in chronic HBV patients, and 30.23% in chronic HCV patients. Logistic regression analysis showed that the subtypes of DM and chronic HCV infection were associated with an increased risk of advanced liver fibrosis in MAFLD patients. Additionally, the subtypes of DM and lean were associated with an increased risk of atherosclerosis, but a decreased risk of atherosclerosis in the subtype of chronic HBV infection., Conclusion: This population-based study proves the concept that subtypes of MAFLD can help risk stratification of clinical outcomes., Competing Interests: Declaration of competing interest All authors declare no conflict and interest., (Copyright © 2023 Formosan Medical Association.

Introduction and Objectives: Chronic hepatitis B (CHB) may progress to more serious liver diseases and it is often accompanied by non-alcoholic fatty liver disease (NAFLD). NAFLD and CHB share risk factors for liver fibrosis and cirrhosis, but the influence of NAFLD on fibrosis progression is controversial. This retrospective study evaluated the prevalence of NAFLD in patients with CHB and investigated associations between NAFLD and liver fibrosis in a large multi-center cohort of hepatitis B patients submitted to liver biopsy., Patients and Methods: Treatment-naïve patients with CHB who underwent liver biopsy were analyzed. Propensity score matching (PSM) was performed to adjust the confounders between patients with and without NAFLD., Results: A total of 1496 CHB patients were included. Two hundred and ninety (19.4%) patients were diagnosed with NAFLD by liver biopsy. The proportions of significant liver fibrosis (52.8% vs. 63.9%, P<0.001), advanced liver fibrosis (27.2% vs. 36.5%, P=0.003), and cirrhosis (13.4% vs. 19.7%, P=0.013) was considerably lower in CHB patients with NAFLD compared to those without NAFLD. 273 patients were included in each group after PSM adjusted for age, sex, hepatitis B envelope antigen status, and hepatitis B virus DNA. Liver fibrosis remained less severe in CHB patients with NAFLD than those without NAFLD (P<0.05) after PSM. The presence of NAFLD was considered an independent negative factor of significant liver fibrosis (odds ratio (OR) 0.692, P=0.013) and advanced liver fibrosis (OR 0.533, P = 0.002) in CHB patients., Conclusions: NAFLD is not uncommon in CHB patients with the prevalence of 19.4%. The presence of NAFLD is associated with less severe liver fibrosis in CHB patients., Of the Study/trial: NCT03097952., Competing Interests: Declaration of interests None., (Copyright © 2023 Fundación Clínica Médica Sur, A.C.

Objectives: We set out to characterise chronic hepatitis B (CHB) in the primary care population in England and investigate risk factors for progression to hepatocellular carcinoma (HCC)., Study Design: Retrospective cohort study., Methods: We identified 8039 individuals with CHB in individuals aged ≥18 years between 1999 and 2019 in the English primary care database QResearch. HCC risk factors were investigated using Cox proportional hazards modelling., Results: Most of those with a record of CHB were males (60%) of non-White ethnicity (>70%), and a high proportion were in the most deprived Townsend deprivation quintile (44%). Among 7029 individuals with longitudinal data, 161 HCC cases occurred. Increased HCC hazards were significantly associated with male sex (adjusted hazards ratio [aHR] 3.17, 95% confidence interval [95% CI] 1.92-5.23), in the fifth deprivation quintile as compared to the third quintile (aHR 1.69, 95% CI 1.01-2.84), with older age (for age groups 56-65 and ≥66 years, compared to 26-35 years, aHRs 2.82 [95% CI 1.45-5.46] and 3.76 [95% CI 1.79-7.9], respectively), Caribbean ethnicity (aHR 3.32, 95% CI 1.43-7.71, compared to White ethnicity), ascites (aHR 3.15, 95% CI 1.30-7.67), cirrhosis (aHR 6.55, 95% CI 4.57-9.38) and peptic ulcer disease (aHR 2.26, 95% CI 1.45-3.51)., Conclusions: Targeting interventions and HCC surveillance at vulnerable groups is essential to improve CHB outcomes and to support progress towards international goals for the elimination of hepatitis infection as a public health threat., (Copyright © 2023 The Authors.

Objectives: Long-term treatment with nucleoside analog (NA) reduces the risks for decompensation and hepatocellular carcinoma (HCC) in chronic hepatitis B (CHB) patients with compensated cirrhosis (CC). However, whether antiviral therapy has differential efficacy on the risks for decompensation and HCC is insufficiently elucidated. Therefore, we investigated the disease state transition, focusing on decompensation event-specific HCC risk in NA-treated CHB patients with CC., Methods: We prospectively followed up on 1163 NA-treated CHB patients with CC every six months for up to seven years. The cumulative incidence and risk of HCC were analyzed by the Kaplan-Meier method and competing risk model. The multistate model was used to estimate the transition probabilities to HCC from different disease states., Results: HCC predominated the first liver-related events, with a 5-year cumulative incidence of 9.0%, followed by decompensation (8.3%, including 7.9% nonbleeding decompensation and 2.4% variceal bleeding) and 0.2% death. The decompensation stage had a significantly higher 5-year cumulative HCC incidence than the CC stage (27.6% vs. 9.1%; HR = 2.42, 95% CI: 1.24, 4.71). Furthermore, nonbleeding decompensation events had a higher 5-year transition probability to HCC than bleeding (27.6% vs. 15.8%; HR = 2.69, 95% CI: 1.41, 4.17). Viral suppression modified the on-treatment transition risk to HCC (1-year: HR = 0.45, 95% CI: 0.28, 0.73; 3-year: HR = 0.23, 95% CI: 0.14, 0.38). An online calculator was developed to facilitate HCC risk stratification., Conclusions: In NA-treated CHB patients with compensated cirrhosis, the risk was higher for HCC than for decompensation; more importantly, different decompensation events conferred distinct HCC risks., (© 2023.

Background: The international recommendations of HCC surveillance for African-born persons with chronic hepatitis B (CHB) without cirrhosis are divergent, probably due to scarce data on incidence rate (IR) for HCC., Methods: We assembled a cohort with prospectively collected data of Swedish residents of African origin with diagnosed CHB without cirrhosis at baseline from 1990 to 2015. Data from nationwide registers were used to calculate the sex-specific IR and IR ratio (incidence rate ratios) in relation to age, comorbidities, and birth region, using a generalized linear model with a log-link function and Poisson distribution., Results: Among 3865 African-born persons with CHB without cirrhosis at baseline, 31 (0.8%; 77.4% men) developed HCC during a median of 11.1 years of follow-up, with poor survival after HCC diagnosis. The mean age at HCC diagnosis was 46.8 (SD±14.7; range 23-79) in men. HCC IR exceeded the recommended surveillance threshold of 0.2%/year at ages 54 and 59 years in men and women, respectively, and at ages 20-40 years if HCV or HDV co-infection was present. African-born men with CHB had an incidence rate ratios of 10.6 (95% CI 4.4-31.5) for HCC compared to matched African-born peers without CHB, and an incidence rate ratios of 35.3 (95% CI 16.0-88.7) compared to a matched general population., Conclusions: African-born men with CHB without cirrhosis reached an IR of 0.2%/year between 50 and 60 years, and at younger ages if HCV or HDV co-infection was present. Our findings need further confirmation, and new cost-effectiveness analyses specific for young populations are needed, to provide personalized and cost-effective HCC surveillance., (Copyright © 2023 The Author(s).

Hepatocellular carcinoma (HCC) is a leading cause of cancer-related death worldwide, and is increasing in incidence in Australia. For most people with cirrhosis and chronic hepatitis B, HCC screening and surveillance is recommended with 6-monthly ultrasound. However, most patients with HCC are still diagnosed outside of surveillance with incurable disease. While HCC surveillance almost certainly reduces cancer-related mortality, the potential harms of surveillance are incompletely understood. Surveillance uptake remains suboptimal in many contexts, and stems from a combination of patient, clinician and system level barriers. Improved case-finding strategies may be required to identify high risk individuals in need of surveillance, as cirrhosis and viral hepatitis are often asymptomatic. HCC prediction models and novel surveillance tools such as biomarker panels, computed tomography and magnetic resonance imaging may have a future role in personalised HCC surveillance. Analyses suggest surveillance may be cost-effective, but Australian data remain limited. A centralised HCC surveillance program may ultimately have a role in delivering improved and more equitable care., (© 2023 The Authors.

Background & Aims: Patients with chronic hepatitis B (CHB) are at increased risk of hepatocellular carcinoma and (liver-related) mortality. In addition to hepatitis B-related factors, metabolic comorbidities may contribute to the progression of fibrosis. Therefore, we studied the association between metabolic comorbidities and adverse clinical outcomes in patients with CHB., Methods: We conducted a retrospective cohort study of CHB patients attending the Erasmus MC University Medical Center (Rotterdam, The Netherlands) and CHB patients who underwent liver biopsy at the Toronto General Hospital (Toronto, Canada). The presence of metabolic comorbidities (ie, overweight, diabetes mellitus, hypertension, and dyslipidemia) was assessed based on chart review. The primary end point was liver-related events, defined as the first composite of hepatocellular carcinoma, liver transplantation, or liver-related mortality., Results: We analyzed 1850 patients, of whom 926 (50.1%) were overweight, 161 (8.7%) had hypertension, 116 (6.3%) had dyslipidemia, and 82 (4.4%) had diabetes. During a median follow-up period of 7.3 years (interquartile range, 2.9-11.5 y), a total of 111 first events were recorded. Hypertension (hazard ratio [HR], 8.3; 95% CI, 5.5-12.7), diabetes (HR, 5.4; 95% CI, 3.2-9.1), dyslipidemia (HR, 2.8; 95% CI, 1.6-4.8), and overweight (HR, 1.7; 95% CI, 1.1-2.5) were associated with an increased risk for liver-related events. The presence of multiple comorbidities further increased the risk. Findings were consistent for patients with and without cirrhosis, among noncirrhotic hepatitis B e antigen-negative patients with hepatitis B virus DNA less than 2000 IU/mL and in multivariable analysis adjusting for age, sex, ethnicity, hepatitis B e antigen status, hepatitis B virus DNA, use of antiviral therapy, and the presence of cirrhosis., Conclusions: Metabolic comorbidities in CHB patients are associated with an increased risk for liver-related events, with the highest risk observed in patients with multiple comorbidities. Findings were consistent in various clinically relevant subgroups, underscoring the need for thorough metabolic assessment in patients with CHB., (Copyright © 2023 The Authors.

Objective: Chronic hepatitis B (CHB) and metabolic dysfunction-associated fatty liver disease (MAFLD) are the leading causes of hepatocellular carcinoma (HCC). We aim to explore the impact of concurrent MAFLD on the risk of HCC in CHB., Methods: Patients with CHB were consecutively recruited from 2006 to 2021. MAFLD was defined by steatosis and either obesity, diabetes mellitus, or other metabolic abnormalities. The cumulative incidence of HCC and associated factors were compared between the MAFLD and non-MAFLD groups., Results: 10,546 treatment-naïve CHB patients were included with a median follow-up of 5.1 years. CHB patients with MAFLD (n = 2212) had fewer hepatitis B e antigen (HBeAg)-positivity, lower HBV DNA levels, and Fibrosis-4 index compared with the non-MAFLD group (n = 8334). MAFLD was independently associated with a 58% reduced risk of HCC (adjusted hazard ratio [aHR] 0.42, 95% confidence interval [CI] 0.25-0.68, p < 0.001). Furthermore, steatosis and metabolic dysfunction had distinct effects on HCC. Steatosis was protective against HCC (aHR 0.45, 95% CI 0.30-0.67, p < 0.001), while a greater burden of metabolic dysfunction increased the risk (aHR 1.40 per dysfunction increase, 95% CI 1.19-1.66, p < 0.001). The protective effect of MAFLD was further confirmed in analysis with inverse probability of treatment weighting (IPTW), patients who had undergone antiviral therapy, those with probable MAFLD, and after multiple imputation for missing data., Conclusions: Concurrent hepatic steatosis is independently associated with a lower risk of HCC, whereas the increasing burden of metabolic dysfunction aggravates the risk of HCC in untreated CHB patients., (© 2023.

Chronic hepatitis B (CHB) and hepatic steatosis (HS) are two prevalent chronic liver diseases in Asia. The incidence of CHB combined with HS is increasing due to the rising obesity rates. However, the impact of HS on CHB remains a topic of debate. Hereby, this meta-analysis aims to examine the effect of HS on Asian patients with CHB. Searches were conducted on four databases to identify articles published from 2005 to 2023. The random-effects or fixed-effects model was used to calculate pooled odds ratios (ORs), weighted mean difference (WMD), and confidence intervals (CIs) for the included articles. Of the 15,959 records screened, 88 studies were included in the analysis of HS prevalence in Asian CHB patients with a prevalence of 36.5% (95% CI: 33.7%-39.3%). In addition, age, sex, body mass index (BMI), waist circumference (WC), alanine aminotransferase (ALT) and combined metabolic diseases have varying degrees of impact on HS in CHB patients. Furthermore, the coexistence of HS was negatively associated with the response to antiviral therapy, including hepatitis B surface antigen (HBeAg) seroconversion (OR = 0.69, 95% CI: 0.53-0.89) and ALT normalization (OR = 0.75, 95% CI: 0.61-0.92) in CHB patients after 48 weeks of treatment. Regarding disease prognosis, HS was not significantly associated with fibrosis or cirrhosis in CHB patients, while an inverse association was observed between HS and hepatocellular carcinoma (HCC) (OR = 2.93, 95% CI: 1.23-6.99). This implies that the coexistence of HS in CHB patients may exacerbate the progression of HCC, which needs to be verified by further studies., (© 2023 John Wiley & Sons Ltd.)

Background: Concomitant Diabetes mellitus (DM) is commonly recognized in patients with chronic hepatitis B (CHB) infection, although its impact on liver-related outcomes remains controversial. We aimed to evaluate the effect of DM on the course, management and outcome of patients with CHB., Methods: We performed a large retrospective cohort study utilizing the Leumit-Health-Service (LHS) database. We reviewed electronic reports of 692106 LHS members from different ethnicities and districts in Israel from 2000-2019 and included patients with CHB diagnosis based on ICD-9-CM codes and supportive serology results. These were divided into two cohorts of patients with CHB and DM (CHD-DM) (N.=252) and those with CHB without DM (N.=964). Clinical parameters, treatment figures and patients' outcomes were compared and multiple regression models and Cox regression analysis were performed to investigate the association between DM and cirrhosis/HCC risk in CHB patients., Results: CHD-DM patients were significantly older (49.2±10.9 vs. 37.9±14, P<0.001), and had higher rates of obesity (BMI>30) and NAFLD (47.2% vs. 23.1%, and 27% vs. 12.6%, P<0.001, respectively). Both groups had a predominance of inactive carrier (HBeAg negative infection) state, but the HBeAg seroconversion rate was significantly lower in the CHB-DM group (25% vs. 45.7%; P<0.01). Multivariable Cox regression analysis showed that DM was independently associated with increased cirrhosis risk (HR 2.63; P=0.002). Older age, advanced fibrosis and DM were associated with HCC, but DM did not reach significance (HR 1.4; P=0.12) possibly due to the small number of HCC cases., Conclusions: Concomitant DM in CHB patients was significantly and independently associated with cirrhosis and possibly with increased risk of HCC.

Rationale and Objectives: To define sarcopenic obesity (SaO) among chronic liver disease (CLD) patients via CT and MRI, and assess its impact on liver disease severity., Materials and Methods: CLD patients referred from the Gastroenterology and Hepatology Department diagnosed as chronic hepatitis B (N:101), cirrhosis (N:110), and hepatocellular carcinoma (N:169) with available information on body height, weight, Child-Pugh and MELD scores within 2 weeks of CT or MRI scanning were included in the study. Cross-sectional examinations were retrospectively evaluated for skeletal muscle index (SMI) and visceral adipose tissue area (VATA). The disease severity was assessed by Child-Pugh and MELD scoring., Results: The rate of sarcopenia and SaO in the cirrhotic patients was higher than that in the chronic hepatitis B patients (p <0.033 and p < 0.004, respectively). The rate of sarcopenia and SaO in HCC patients was higher than that in the chronic hepatitis B patients (p <0.001 and p <0.001, respectively). Sarcopenic patients in Chronic hepatitis B, cirrhotic, and HCC groups had higher MELD scores than nonsarcopenic patients (p <0.035, p <0.023, and p <0.024, respectively). Despite finding a similar increase in Child-Pugh scores in cirrhotic and HCC sarcopenic patients, results were statistically insignificant (p <0.597 and p <0.688). HCC patients with SaO had higher MELD scores than patients with other body composition catagories (p <0.006). Cirrhotic patients with SaO had higher MELD scores than nonsarcopenic obese patients (p <0.049). Chronic hepatitis B patients with obesity had low MELD scores (p <0.035). Cirrhotic and HCC patients with obesity had higher MELD scores (p <0.01 and p <0.024, respectively). Cirrhotic and HCC patients with obesity had higher Child-Pugh scores than nonobese patients but only HCC patients showed statistically significance (p <0.480 and p <0.001)., Conclusion: Radiologic evaluation of SaO and harmonizing body composition with MELD scoring is critical in CLD management., Competing Interests: Declaration of Competing Interest None., (Copyright © 2023 The Association of University Radiologists.

Introduction: Despite improvements in the management of chronic hepatitis B (CHB), risk of cirrhosis and hepatocellular carcinoma remains. While hepatitis B surface antigen loss is the optimal end point, safe discontinuation of nucleos(t)ide analog (NA) therapy is controversial because of the possibility of severe or fatal reactivation flares., Methods: This is a multicenter cohort study of virally suppressed, end-of-therapy (EOT) hepatitis B e antigen (HBeAg)-negative CHB patients who stopped NA therapy (n = 1,557). Survival analysis techniques were used to analyze off-therapy rates of hepatic decompensation and differences by patient characteristics. We also examined a subgroup of noncirrhotic patients with consolidation therapy of ≥12 months before cessation (n = 1,289). Hepatic decompensation was considered related to therapy cessation if diagnosed off therapy or within 6 months of starting retreatment., Results: Among the total cohort (11.8% diagnosed with cirrhosis, 84.2% start-of-therapy HBeAg-negative), 20 developed hepatic decompensation after NA cessation; 10 events were among the subgroup. The cumulative incidence of hepatic decompensation at 60 months off therapy among the total cohort and subgroup was 1.8% and 1.1%, respectively. The hepatic decompensation rate was higher among patients with cirrhosis (hazard ratio [HR] 5.08, P < 0.001) and start-of-therapy HBeAg-positive patients (HR 5.23, P < 0.001). This association between start-of-therapy HBeAg status and hepatic decompensation remained significant even among the subgroup (HR 10.5, P < 0.001)., Discussion: Patients with cirrhosis and start-of-therapy HBeAg-positive patients should be carefully assessed before stopping NAs to prevent hepatic decompensation. Frequent monitoring of viral and host kinetics after cessation is crucial to determine patient outcome., (Copyright © 2023 by The American College of Gastroenterology.)

Chronic hepatitis B virus (HBV) infection affects about 296 million people worldwide and is the leading aetiology of cirrhosis and liver cancer globally. Major medical complications also include acute flares and extrahepatic manifestations. In addition, people living with HBV infection also experience stigma. HBV-related cirrhosis resulted in an estimated 331,000 deaths in 2019, and it is estimated that the number of deaths from HBV-related liver cancer in 2019 was 192,000, an increase from 156,000 in 2010. Meanwhile, HBV remains severely underdiagnosed and effective measures that can prevent infection and disease progression are underutilized. Birth dose coverage for HBV vaccines remains low, particularly in low-income countries or regions where HBV burden is high. Patients with HBV infection are inadequately evaluated and linked to care and are undertreated worldwide, even in high-income countries or regions. Despite the goal of the World Health Organization to eliminate viral hepatitis as a public health problem by 2030, the annual global deaths from HBV are projected to increase by 39% from 2015 to 2030 if the status quo remains. In this Review, we discuss the current status and future projections of the global burden of HBV infection. We also discuss gaps in the current care cascade and propose future directions., (© 2023.

Background: Finite nucleos(t)ide analogue (NUC) therapy has been proposed as an alternative treatment strategy for chronic hepatitis B (CHB)., Aim: To quantify the incidence of severe hepatitis flares following NUC cessation in everyday clinical practice., Methods: This population-based cohort study enrolled 10,192 patients (male 71.7%, median age 50.9 years, cirrhosis 10.7%) who had received first-line NUCs for at least 1 year before discontinuing treatment. The primary outcome was severe flare with hepatic decompensation. We used competing risk analyses to assess event incidences and associated risk factors., Results: During a median follow-up of 2.2 years, 132 patients developed severe flares with hepatic decompensation, yielding a 4-year cumulative incidence of 1.8% (95% confidence interval [CI], 1.5%-2.2%). Significant risk factors were cirrhosis (adjusted sub-distributional hazard ratio [aSHR], 2.74; 95% CI, 1.82-4.12), manifestations of portal hypertension (aSHR, 2.46; 95% CI, 1.45-4.18), age (aSHR, 1.21 per 10 years; 95% CI, 1.03-1.42) and male sex (aSHR, 1.58; 95% CI, 1.04-2.38). In patients without cirrhosis or portal hypertension (n = 8863), the 4-year cumulative incidence of severe withdrawal flares stood at 1.3% (95% CI, 1.0%-1.7%). For those patients with available data confirming adherence to the standard stopping rules (n = 1274), the incidence was 1.1% (95% CI, 0.6%-2.0%)., Conclusions: Severe flares with hepatic decompensation were observed in 1%-2% of patients with CHB after stopping NUC therapy in daily practice. Risk factors included older age, cirrhosis, portal hypertension and male sex. Our findings argue against NUC cessation as part of routine clinical care., (© 2023 John Wiley & Sons Ltd.)

Chronic hepatitis B (HBV) infection is a disease that imposes a considerable financial burden on patients and can lead to sleep disorders (SDs), resulting in a serious deterioration to patient quality of life. This study aimed to determine the prevalence of SDs in patients with HBV and the correlated sociodemographic and clinical characteristics. A total of 747 patients with chronic HBV infection were recruited. All patients completed the Pittsburgh Sleep Quality Index (PSQI), Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 scale, Social Support Rating Scale, Short Form 36 Health Survey (SF-36), and Visual Analogue Scale (VAS). The total PSQI score of patients with each type of chronic HBV infection was significantly higher compared to healthy Chinese adults (p < .05). The incidence of SDs in HBV carriers and patients with mild HBV, moderate HBV, severe HBV, liver failure, compensated cirrhosis, and decompensated liver cirrhosis was 25%, 26%, 32%, 47%, 56%, 31%, and 49%, respectively. The incidence of SDs in all patients with chronic HBV infection was 30%. Binary logistic regression analysis revealed that the course of disease, aspartate aminotransferase levels, PHQ-9 scores, and VAS scores were independent risk factors for SDs, while the total SF-36 score was a protective factor for SDs (all p < .05). In conclusion, the prevalence of SDs was significantly higher in patients with chronic hepatitis B compared to healthy subjects. The independent risk factors for SDs included disease duration, aspartate aminotransferase levels, depression, and fatigue. Clinicians should pay more attention to SDs in patients with chronic HBV infection., (© 2023 John Wiley & Sons Ltd.)

Background and Aims: Chronic hepatitis B infection (defined as sustained detection of hepatitis B virus [HBV] surface antigen [HBsAg] protein in serum) is a leading cause of cirrhosis, hepatocellular carcinoma and liver-related deaths. A situation analysis carried out by the Swiss Federal Office of Public Health estimated the HBsAg prevalence in Switzerland to be 0.53% (95% CI: 0.32-0.89%) in 2015 (~44,000 cases). A lower prevalence of chronic HBV in the younger generation and the adoption of universal coverage in the first year of life are expected to decrease the burden of HBV; however, a number of people in key populations (including migrants) remain undiagnosed and untreated, and infected individuals remain at risk of progressing to cirrhosis, hepatocellular carcinoma and death. Our primary objective was to examine the current and estimate the future disease burden of HBV in Switzerland and the impact of migration. The secondary objective was to estimate the impact of changing future treatment numbers., Methods: A modelling study was performed using an existing, validated model (PRoGReSs Model) applied to the Swiss context. Model inputs were selected through a literature search and expert consensus. Population data from the Federal Statistical Office were used alongside prevalence data from the Polaris Observatory to estimate the number of HBV infections among people born abroad. The PRoGReSs Model was populated with and calibrated to the available data and what-if scenarios were developed to explore the impact of intervention on the future burden of disease. A Monte Carlo simulation was used to estimate 95% uncertainty intervals (95% UIs)., Results: In 2020, there were an estimated 50,100 (95% UI: 47,500-55,000) HBsAg+ cases among people born abroad. Among people born in Switzerland, there were approximately 62,700 (UI: 58,900-68,400) total HBV infections (0.72% [UI: 0.68-0.79%] prevalence). Prevalence among infants and children under the age of 5 were both <0.1%. By 2030, prevalence of HBV is expected to decrease, although morbidity and mortality will increase. Increasing diagnosis (90%) and treatment (80% of those eligible) to meet the global health sector strategy on viral hepatitis programme targets could prevent 120 cases of hepatocellular carcinoma and 120 liver-related deaths., Conclusions: Thanks to the historical vaccination programmes and the continued rollout of universal 3-dose coverage in the first year of life, Switzerland is expected to exceed the global health sector strategy targets for the reduction of incidence. While overall prevalence is decreasing, the current diagnosis and treatment levels remain below global health sector strategy targets.

Failure to access antiviral medications is a leading cause of hepatitis B (HBV)-associated morbidity and mortality in sub-Saharan Africa (SSA). Despite guideline availability, SSA is not on course to meet its elimination targets. We characterized factors associated with antiviral medication use and challenges to offering chronic care in a large Ugandan institution. We abstracted HBV care data. 2,175/2,209 (98.5%) had HBV-infection. Most participants were men [1,197 (55%)]; median (IQR) age 27 years (19-35); 388/1689 (23.0%) had cirrhosis by sonography and 141/2175 (6.5%) by the aspartate aminotransferase to platelet ratio index (APRI) score ≥2. Of the eligible, 20/141 (14.2%) with APRI score ≥2 and 24/388 (6.2%) with sonographic evidence of liver cirrhosis were not on antiviral medications. Overall, 1,106 (51%) were on medications though 65.8% had not been fully investigated. In multivariate analysis, age ≥35 years [OR (95% CI) = 1.52 (1.01-2.28), p=0.043], APRI ≥2 [OR (95% CI) =1.79 (1.482.16), p<0.001], hepatitis B viral load >2,000IU/mL [OR (95% CI) = 6.22 (5.08-7.62), p<0.001] were associated with antiviral medications use. Over half of participants in care had not been fully evaluated although on treatment and many eligible patients did not access medications. There is need to bridge these gaps for SSA to realise its HBV elimination goals., (© 2023 Seremba E et al.)

Despite a high prevalence, there are few successful models for de-centralizing diagnosis and treatment of chronic hepatitis B virus (HBV) infection among rural communities in Sub-Saharan Africa. We report baseline characteristics and 1 year retention outcomes for patients enrolled in a HBV clinic integrated within chronic disease services in a rural district hospital in Sierra Leone. We conducted a retrospective cohort study of patients with HBV infection enrolled between 30 April 2019 and 30 April 2021. Patients were eligible for 1 year follow-up if enrolled before 28 February 2020. Treatment eligibility at baseline was defined as cirrhosis (diagnosed by clinical criteria of decompensated cirrhosis, ultrasonographic findings or aspartate-aminotransferase-to-platelet ratio >2) or co-infection with HIV or HCV. Retention in care was defined as a documented follow-up visit at least 1 year after enrolment. We enrolled 623 individuals in care, median age of 30 years (IQR 23-40). Of 617 patients with available data, 97 (15.7%) had cirrhosis. Treatment was indicated among 113 (18.3%) patients and initiated among 74 (65.5%). Of 39 patients eligible for 1 year follow-up on treatment at baseline, 20 (51.3%) were retained at 1 year, among whom 12 (60.0%) had documented viral suppression. Among the 232 patients not initiated on treatment eligible for 1 year follow-up, 75 (32.3%) were retained at 1 year. Although further interventions are required to improve outcomes, our findings demonstrated feasibility of retention and treatment of patients with HBV infection in a rural district in Sub-Saharan Africa, when integrated with other chronic disease services., (© 2023 John Wiley & Sons Ltd.)

Background: Chronic hepatitis B (CHB) is endemic to Asia and is a leading cause of liver-related morbidity. The prevalence of concomitant CHB and hepatic steatosis (HS) is increasing in Asia. Non-invasive tests (NITs) including FIB-4, NFS and APRI assess fibrosis in populations with a single aetiology, but not in subjects with concomitant CHB and HS., Aim: To explore the accuracy of NITs in predicting advanced fibrosis in patients with concomitant CHB and HS., Methodology: This multicentre study of CHB patients who underwent liver biopsy explored clinical characteristics of these subjects, stratified by presence of HS. Fibrosis scores from NITs were compared against histological fibrosis stage in CHB subjects with and without HS., Results: 2262 subjects were enrolled, 74.5% were males, and the mean age was 39.5 years ±11.8 SD. 984 (44.4%) had HS, 824 (36.4%) had advanced fibrosis. In the CHB group, the AUROC for advanced fibrosis were 0.65 (95% CI 0.62-0.69) for FIB-4 and 0.63 (95% CI 0.60-0.66) for APRI. The specificities were 0.94 for FIB-4 greater than 3.25 and 0.81 for APRI greater than 1.5. In the CHBHS group, the AUROC for advanced fibrosis were 0.67 (95% CI 0.63-0.71) for FIB-4, 0.60 (95% CI 0.56-0.64) for APRI and 0.65 (95% CI 0.61-0.69) for NFS. The specificities were 0.95 for FIB-4 greater than 3.25, 0.88 for APRI greater than 1.5 and 0.99 for NFS greater than 0.675., Conclusion: The performance of NITs to exclude advanced fibrosis did not differ greatly regardless of HS. FIB-4 and NFS have the best negative predictive values of 0.80 and 0.78, respectively, to exclude advanced fibrosis in CHBHS subjects., (© 2023 John Wiley & Sons A/S.

Background: Aboriginal and Torres Strait Islander Australians living with chronic hepatitis B virus (HBV) infection have a significant burden of hepatocellular carcinoma (HCC). The prevalence of comorbidities that increase the risk of HCC in this population is incompletely defined., Methods: This cross-sectional study was performed in remote tropical Queensland, Australia in January 2021. All individuals living with chronic HBV in the region were identified; the prevalence of relevant comorbidities was determined by reviewing medical records., Results: All 236 individuals in the cohort identified as Aboriginal and Torres Strait Islander Australians; their median (interquartile range (IQR)) age was 48 (40-62) years; 120/236 (50.9%) were female. Of the 194/236 (82.2%) engaged in HBV care, 61 (31.4%) met criteria for HBV therapy and 38 (62.2%) were receiving it. However, 142/236 (60.2%) were obese, 73/236 (30.9%) were current smokers and 57/236 (24.2%) were drinking alcohol hazardously; 70/236 (29.7%) had ≥2 of these additional risk factors for HCC, only 43/236 (18.2%) had none. Among the 19 patients with confirmed cirrhosis, 9 (47%) were obese, 8 (42%) were currently-or had a history of-drinking alcohol hazardously and 5 (26.3%) were current smokers. Patients also had a median (IQR) of 3 (2-4) cardiovascular risk factors (cigarette smoking, hypertension, impaired glucose tolerance, dyslipidaemia, renal impairment/proteinuria). Only 9/236 (3.8%) did not have one of these 5 comorbidities., Conclusions: Aboriginal and Torres Strait Islander Australians living with chronic HBV in this region of remote Australia have a high engagement with HBV care and the majority of individuals eligible for antiviral therapy are receiving it. However, a significant comorbidity burden increases their risk of cirrhosis, HCC, and premature death. It is essential to integrate chronic HBV care with management of these comorbidities-rather than focusing on HBV alone-to achieve optimal health outcomes., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Riddell et al.

Background: Chronic hepatitis B (CHB) carries an increased risk of death from cirrhosis and hepatocellular carcinoma (HCC). The American Association for the Study of Liver Diseases recommends patients with CHB receive monitoring of disease activity, including ALT, hepatitis B virus (HBV) DNA, hepatitis B e-antigen (HBeAg), and liver imaging for patients who experience an increased risk for HCC. HBV antiviral therapy is recommended for patients with active hepatitis and cirrhosis., Methods: Monitoring and treatment of adults with new CHB diagnoses were analyzed using Optum Clinformatics Data Mart Database claims data from January 1, 2016, to December 31, 2019., Results: Among 5978 patients with new CHB diagnosis, only 56% with cirrhosis and 50% without cirrhosis had claims for≥1 ALT and either HBV DNA or HBeAg test, and among patients recommended for HCC surveillance, 82% with cirrhosis and 57% without cirrhosis had claims for≥1 liver imaging within 12 months of diagnosis. Although antiviral treatment is recommended for patients with cirrhosis, only 29% of patients with cirrhosis had≥1 claim for HBV antiviral therapy within 12 months of CHB diagnosis. Multivariable analysis showed patients who were male, Asian, privately insured, or had cirrhosis were more likely (P<0.05) to receive ALT and either HBV DNA or HBeAg tests and HBV antiviral therapy within 12 months of diagnosis., Conclusion: Many patients diagnosed with CHB are not receiving the clinical assessment and treatment recommended. A comprehensive initiative is needed to address the patient, provider, and system-related barriers to improve the clinical management of CHB., Competing Interests: The authors declare no conflict of interest., (Copyright © 2023 The Author(s).

Background and Aims: Treatment indications for chronic hepatitis B (CHB) differ among recommendations by European Association for the Study of the Liver (EASL), American Association for the Study of Liver Diseases (AASLD) and World Health Organization (WHO). We aimed to assess treatment eligibility and linkage to therapy at a large tertiary care center., Methods: All CHB patients who were evaluated for treatment at the Vienna General Hospital between January 2010 and December 2020 were retrospectively included. Clinical, virological, and long-term treatment efficacy data were analyzed., Results: A total of 751 CHB patients were included (53.3% male; median age: 39.5 years; HBeAg-positive: 10.8%). The median Hepatitis B Virus (HBV)-DNA and HBsAg levels were 569 (68-11,750) IU/mL and 3467.65 (620.05-11,935.43) IU/mL, respectively. Overall, 9.2% of patients had severe fibrosis/cirrhosis, and 5.7% were coinfected with hepatitis D virus (HDV), which was highly prevalent in cirrhosis. According to the recent EASL nomenclature, 3.2% of patients had HBeAg-positive chronic infection, 7.6% had HBeAg-positive chronic hepatitis, 58.9% had HBeAg-negative chronic infection, and 30.4% had HBeAg-negative chronic hepatitis. At the time of evaluation, 36.4% had HBV-DNA >2000 IU/mL, and 37.3% showed alanine aminotransferase >40 U/L. Ultimately, 26.9% (EASL), 29.0% (AASLD) and 23.4% (WHO) met the treatment criteria. Treatment was initiated in most patients, mainly with tenofovir (61.8%) or entecavir (34.9%). Treatment efficiently suppressed HBV-DNA in all patients; however, HBsAg loss was observed only in 2.8% at 5 years of therapy., Conclusions: Severe fibrosis/cirrhosis was found in 9.2% of CHB patients at presentation, and 23.4%-29.5% met current treatment recommendations with a high treatment uptake of 79.8%-89.2% among eligible patients., (© 2023 The Authors.

Background & Aim: HBV epidemiology is highly heterogeneous and rapidly evolving worldwide: we studied its last two-decades dynamics in a large single center cohort., Methods: In all consecutive HBsAg-positive subjects firstly admitted (2000-2019) at the Pisa-University-Hospital Hepatology-Referral-Center, demographic, virologic and clinical variables were analyzed by admission decade (2000-2009 vs 2010-2019) and origin (Italian vs non-Italian natives)., Results: Of 2003, 1878 (93.7%) subjects were eligible: 1798(95.7%) with HBV-chronic [126(7%) HDV, 72(4%) HCV, 11(0.6%) HIV co-infected] and 80(4.3%) HBV-primary infections (93.7% Italians). Among 1589(88.4%) mono-infected, 496(31.2%) were immigrants, younger than Italians [34.0(5.1-77.1)-52.5(10.0-87.2) years], with female prevalence [204/496(41.1%)-340/1093(31.1%); p<0.001] increasing overtime (14.6-45.0%; p<0.001). Italians aged across decades [50.3(11.1-87.2)-56.2(10.0-86.7) years; p<0.001], HBeAg-positivity remained stable (12.3-14.5%) and acute hepatitis increased (4.0-8.0%; p = 0.003). CHB declined [439/721(60.9%)-320/868(36.9%); p<0.001] whereas HBeAg-negative infection increased [277/626(44.2%)-538/755(71.3%); p<0.001]. Cirrhosis declined [195/721(27.0%)-125/868(14.4%); p<0.001], except in anti-HDV-patients [93/126(73.8%); 42(45.1%) non-Italians], younger than HBV-mono-infected (47.4-57.6 years; p<0.001)., Conclusion: Effective preventive health care policies and immigration flows account for increasing prevalence of HBeAg-negative infection across the last two decades. Antiviral therapy mitigated disease progression in aging Italian CHB but not in CHD patients, mainly young immigrants, emphasizing the unmet need of effective CHD therapies; HBeAg-positive CHB and acute hepatitis B persist in non-vaccinated Italian adults, prompting vaccination in the elderly with risky behaviors., Competing Interests: Conflict of interest Ferruccio Bonino has served as a speaker for Fujirebio, Gilead and Roche.

Background & Aims: The incidence of chronic hepatitis B (CHB) is declining due to successful implementation of vaccination programs and widespread use of antiviral therapy. We aimed to study time-trends in disease characteristics and comorbidities in newly referred CHB patients., Methods: We collected information on hepatitis B virus (HBV) related disease characteristics (including hepatitis B e-antigen (HBeAg) status, viremia, stage of liver fibrosis and indication for treatment and/or hepatocellular carcinoma (HCC) surveillance) and presence of comorbidities in all CHB patients referred to our center from 1980 through 2020. Patient characteristics were compared according to referral date (before 2000, between 2000 and 2010 and after 2010)., Results: We identified 1515 eligible patients. Patients referred after 2010 were older (36 versus 34 years, p < 0.001), more often non-Caucasian (82.3% versus 55.0%, p < 0.001) and more frequently HBeAg negative (81.5% versus 49.8%, p < 0.001) when compared to patients referred before 2000. Adjusted for ethnicity, sex and age, patients referred after 2010 were less likely to have significant fibrosis (adjusted odds ratio [aOR]:0.178, p < 0.001) or indication for antiviral therapy (aOR:0.342, p < 0.001) but were more likely to be affected by the metabolic syndrome (aOR:1.985, p = 0.013), hepatic steatosis (aOR:1.727, p < 0.001) and metabolic dysfunction associated fatty liver disease (MAFLD) (aOR:1.438, p = 0.013)., Conclusions: The characteristics of the CHB populations are changing. Newly referred patients are older, have less active HBV related liver disease but are more likely to be co-affected by MAFLD. These findings provide guidance for adequate allocation of resources to cope with the changing characteristics of the CHB population., Funding: Foundation for Liver and Gastrointestinal Research Rotterdam, the Netherlands and Gilead Sciences., (Copyright © 2022 The Author(s).

Background: Chronic hepatitis B virus (HBV) is a major public health concern. Transient elastrography (TE) is a reliable method in assessing hepatic fibrosis in patients with liver disease. We assess the potential clinical associations between HBsAg seroclearance and the severity of liver fibrosis., Methods: We retrospectively performed a matched analysis of 23 consecutive HBsAg seroclearance patients who underwent TE between March 2008 and August 2021 from a community practice at a 1:3 ratio based on clinic visit date. Baseline laboratory and clinical data were collected. Fisher's exact test and Chi-square test for proportions, and Wilcoxon rank-sum test for median were performed., Results: Twenty-three cases and 69 controls were identified. Median follow up (interquartile range) for the cases and controls was 24,314 (1402) and 2332 (1587) days (p  =  0.15), respectively. All patients were Asian. Median age of cases was higher than controls (64 vs 52, p < 0.01, respectively). While most comorbidities were similar, diabetes and hyperlipidemia were more prevalent in cases. Baseline HBV DNA was detectable in 78% of cases and 97% of controls (p < 0.01). More cases had baseline HBsAg titers below 1000 IU/mL than controls (81% vs 8.7%, p < 0.01). Other baseline laboratory values were similar. Few cases had a fibrosis score greater than 1, while control had over a quarter of patients with a fibrosis score of 2 or 3., Conclusion: Spontaneous HBsAg seroclearance remains rare in patients with chronic HBV infection. It is associated with low baseline HBsAg, and lower level of liver fibrosis as detected by TE., (© 2022.

Background: Finland is among the countries with low hepatitis B endemicity. We evaluate the hepatitis B-related disease and economic burden needed for evidence-based immunisation policy decision-making., Methods: Hepatitis B-related cases in 2004-2012 were retrieved from population-based nationwide registers. We evaluated the incidence, health care resource use, health care costs, and life years lost due to hepatitis B-related outcomes. An episode of care was constructed from each individual's hepatitis B-related events retrieved from individually linkable registers., Results: The mean health care costs per an acute hepatitis B case were €450 ( SD 240), €2030 ( SD 350), and €5400 ( SD 3370) in those aged 0-14, 15-64, and ≥65 years, respectively. For chronic infection, the mean cost per case among Finnish-born individuals was €990 and among foreign-born €1360. The costs per case of liver cirrhosis were €15,350 and liver cancer €19,080. In addition, the annual antiviral medication costs per case receiving antiviral medication were €4710 to €5530. Annually <10% of the chronic and approximately 20% of liver cirrhosis cases received antiviral medication. We identified annually 21 acute, 264 chronic, three liver cirrhosis, and four liver cancer cases and 63.7 life years lost due to hepatitis B per 5.3 million inhabitants. The total annual health care costs were €1.2 million of which 60% were antiviral medication costs and 86% accounted for chronic hepatitis B., Conclusions: When planning prevention of hepatitis B infection, it is pivotal to notice that the overall disease and economic burden due to hepatitis B is mostly due to chronic infection.

Hepatitis B virus (HBV) is intrinsically oncogenic and related to hepatocellular carcinoma (HCC). Predictive scores of HCC have been developed but have been poorly studied in admixed populations. Therefore, we aimed to evaluate the performance of PAGE-B and mPAGE-B scores for HCC prediction in HBV Brazilian patients and factors related to HCC occurrence. This is a retrospective study that evaluated patients followed at a tertiary university center. A total of 224 patients were included, with a median follow-up period of 9 years. The mean age at HBV diagnosis was 38.71 ± 14.19 years, predominantly males (66.1%). The cumulative incidence of HCC at 3, 5, and 7 years was 0.993%, 2.70%, and 5.25%, respectively, being related in the univariate logistic regression analysis to male sex (p = 0.0461), older age (p = 0.0001), cirrhosis at HBV diagnosis (p < 0.0001), and higher values of PAGE-B and mPAGE-B scores (p = 0.0002 and p < 0.0001, respectively). Older age, male sex, and cirrhosis at HBV diagnosis were independently associated with HCC occurrence. The AUROCs of PAGE-B and mPAGE-B were 0.7906 and 0.7904, respectively, with no differences between them (p = 0.9767). In conclusion, both PAGE-B and mPAGE-B showed a correct prediction of HCC above 70% in this cohort.

Chronic hepatitis B virus (HBV) infection is a major risk factor for hepatocellular carcinoma (HCC), and surveillance is recommended for patients without cirrhosis when risk exceeds an incidence rate (IR) of 0.2%. Populations in Asia and sub-Saharan Africa have been associated with HCC at younger ages, but the risk after immigration to Western countries should be investigated. The aim of this study was to study HCC by age and country of origin in people with chronic HBV infection in Sweden. Through national registers, residents with chronic HBV diagnosis (1990-2015) were identified with information on country of origin, immigration/emigration, death, coinfections, antiviral therapy, and HCC. Observation time started at HBV diagnosis, and IR and hazard ratios for HCC were calculated by sex, age, and region of origin. Among 16,410 individuals (47% women), the origin and observation time (person years) were as follows: Western Europe, 2316 (25,415); Eastern Europe, 2349 (26,237); Middle East/North Africa, 4402 (47,320); sub-Saharan Africa, 3677 (30,565); Asia, 3537 (35,358); and other, 129 (1277). There were 232 individuals with HCC (82% in men). The IR increased with age and exceeded 0.2% for Asian men from age group 40-49 years (IR, 0.63; 95% confidence interval, 0.39-1.00), for men of other origins from age group 50-59 years, and for women aged ≥60 years originating from Eastern Europe, Asia, and Middle East/North Africa. After exclusion of patients with cirrhosis or HBV treatment, the IR still exceeded 0.2% in Asian men aged 40-49 years. This study demonstrates that HBV-infected men of Asian origin should be recommended HCC surveillance at younger ages, but there is a need for further studies of HCC incidence in African-born men without cirrhosis living in the Western world., (© 2022 The Authors.

Background & Aims: After hepatitis B surface antigen (HBsAg) seroclearance, the risk of hepatocellular carcinoma (HCC) remains, and the optimal surveillance strategy has yet to be determined. Herein, we aimed to evaluate incidence and risk factors for HCC and establish a novel prediction model for HCC development after HBsAg seroclearance., Methods: A total of 1,443 patients with chronic hepatitis B who achieved HBsAg seroclearance between 1991 and 2020 were retrospectively screened for study eligibility. The data from 831 of these patients were included in the final analysis. A prediction model was developed based on multivariable Cox models. Harrell's C-index and a time-dependent AUROC were used for discrimination. Bootstrap analysis was performed for internal validation., Results: Overall, 40 patients (4.8%) developed HCC after HBsAg seroclearance during a follow-up of 4,644 person-years (0.86%/year). Age at HBsAg seroclearance, presence of cirrhosis, family history of HCC, and more-than-moderate alcohol consumption were independently predictive of HCC, and these 4 independent variables were used to develop the prediction model. The C-index of the model was 0.804. The time-dependent AUROCs of the score for HCC prediction at 5, 10, and 15 years were 0.799, 0.835, and 0.817, respectively. The score also showed good discrimination in the internal validation and sensitivity analysis., Conclusions: The novel prediction model based on age, cirrhosis, family history of HCC, and alcohol consumption enables reliable risk estimation of HCC after HBsAg seroclearance and may serve as a useful reference for decision-making in HCC surveillance for HBsAg-cleared patients., Lay Summary: After spontaneous hepatitis B surface antigen (HBsAg) seroclearance, the risk of hepatocellular carcinoma (HCC) remains. Age at HBsAg seroclearance, presence of cirrhosis, family history of HCC, and more-than-moderate alcohol consumption were independently associated with HCC development after HBsAg seroclearance. The novel prediction model using these 4 variables enables reliable risk estimation of HCC and serves as a useful reference for decision-making in HCC surveillance and management for HBsAg-cleared patients., Competing Interests: Conflict of interest The authors declare no conflicts of interest that pertain to this work.

Many studies have elucidated the protective associations of statin use with liver cancer or mortality, but studies examining statin's effect on the risk of progression to liver cirrhosis considering medical/metabolic conditions or lifestyle factors are lacking. We aimed to assess statin's benefit independent of conventional risk factors. We identified 25,033 pairs of statin users (using statins for ≥90 days) and nonusers among patients with chronic hepatitis B (CHB) in the Republic of Korea's National Health Insurance Service database from 2010 to 2018. The primary endpoint was progression to cirrhosis from an inactive carrier or simple CHB. The cumulative probability was plotted using the Kaplan-Meier method. Adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs) were estimated using the multivariable Cox proportional hazard model. During a 218,472 person-year follow-up, 2210 incident cases of progression to cirrhosis occurred. The 5-year cumulative risks were 4.0% and 6.3% in statin users and nonusers, respectively (p < 0.001). Statin use was significantly associated with a decreased risk of progression to cirrhosis (aHR, 0.59; 95% CI, 0.55-0.65; p < 0.001), after adjusting for age, sex, hypertension, diabetes, dyslipidemia, antiviral therapy, aspirin use, metformin use, nonstatin medication for dyslipidemia, smoking, drinking, obesity, exercise, and liver dysfunction. This protective association was still significant in a dose-response manner and with different time lags for outcomes. Conclusion: Statin use is associated with a decreased risk of progression to cirrhosis among patients with CHB, independent of metabolic and lifestyle factors. Future studies are required to validate this observation., (© 2022 The Authors.

Background & Aims: Many patients with chronic hepatitis B (CHB) may not conform to any of the defined phases and hence are classified as indeterminate. We aimed to characterize the baseline prevalence of indeterminate patients and their natural history, phase transition, and hepatocellular carcinoma (HCC) risk., Methods: This was a retrospective cohort study of 3366 adult untreated noncirrhotic CHB patients seen at 5 US clinics and 7 Taiwanese townships who had at least 1 year of serial laboratory data before enrollment with a mean follow-up period of 12.5 years. Patients' clinical phases were determined at baseline and through serial data during follow-up evaluation, based on the American Association for the Study of Liver Diseases 2018 guidance., Results: At baseline, 1303 (38.7%) patients were in the indeterminate phase. By up to year 10 of follow-up evaluation, 686 patients (52.7%) remained indeterminate, while 283 patients (21.7%) became immune active. Compared with patients who remained inactive, patients who remained indeterminate had a higher 10-year cumulative HCC incidence (4.6% vs 0.5%; P < .0001) and adjusted hazard ratio for HCC of 14.1 (P = .03). Among patients who remained indeterminate, age 45 years and older (adjusted hazard ratio, 18.4; P = .005) was associated independently with HCC development., Conclusions: Nearly 40% of patients had indeterminate CHB phase. Of these, half remained indeterminate and one-fifth transitioned to the immune active phase. HCC risk in persistently indeterminate CHB was 14 times higher than inactive CHB. Among persistently indeterminate CHB patients, age 45 years and older was associated with an 18 times higher risk for HCC development. Further studies are needed to evaluate the potential benefit of antiviral therapy for indeterminate patients, especially in the older subgroup., (Copyright © 2022 AGA Institute.

Background and Aims: Studies on differential effect of aspirin therapy on HCC risk across the spectrum of liver diseases are lacking. We investigated the association between aspirin use and risks of HCC, liver-associated death, and major bleeding in chronic hepatitis B (CHB) patients with or without cirrhosis., Approach and Results: We identified 329,635 eligible adults with CHB from 2007 through 2017, using the Korean National Health Insurance Service database, including patients who received aspirin for ≥90 consecutive days (n = 20,200) and patients who never received antiplatelet therapy (n = 309,435). Risks of HCC, liver-associated mortality, and major bleeding were estimated in a propensity-score-matched cohort (19,003 pairs), accounting for competing risks. With a median follow-up of 6.7 years, 10-year cumulative incidence of HCC was 9.5% in the aspirin-treated group and 11.3% in the untreated group (adjusted subdistribution hazard ratio [aSHR], 0.85; 95% CI, 0.78-0.92). However, among patients with cirrhosis (2479 pairs), an association of aspirin use with HCC risk was not evident (aSHR, 1.00; 95% CI, 0.85-1.18). Cirrhosis status had a significant effect on the association between aspirin use and HCC risk (p interaction , n = 0.04). Aspirin use was also associated with lower liver-associated mortality (aSHR, 0.80; 95% CI, 0.71-0.90). Moreover, aspirin use was not associated with major bleeding risk (aSHR, 1.09; 95% CI, 0.99-1.21)., Conclusions: Aspirin use was associated with reduced risks of HCC and liver-associated mortality in adults with CHB. Cirrhosis status had a substantial effect on the association between aspirin use and HCC risk., (© 2022 American Association for the Study of Liver Diseases.)

Hepatitis B virus (HBV) infection is the first cause of liver cirrhosis and cancer in West Africa. Although the exposure to additional environmental and infectious risk factors may lead to the faster progression of liver disease, few large-scale studies have evaluated the determinants of HBV-related liver fibrosis in the region. We used transient elastography to evaluate the prevalence of liver fibrosis and assessed the association between HBV markers and significant liver fibrosis in a cohort of people living with HBV in Dakar, Senegal. The prevalence of significant liver fibrosis was 12.5% (95% confidence interval [CI] 9.6%−15.9%) among 471 people with HBV mono-infection (pwHBV) and 6.4% (95% CI 2.6%−12.7%) in 110 people with HIV/HBV co-infection (pwHIV/HBV) on tenofovir-containing antiretroviral therapy (p = 0.07). An HBV viral load > 2000 IU/mL was found in 133 (28.3%) pwHBV and 5 (4.7%) pwHIV/HBV, and was associated with significant liver fibrosis (adjusted odds ratio (aOR) 1.95, 95% CI 1.04−3.66). Male participants (aOR 4.32, 95% CI 2.01−8.96) and those with elevated ALT (aOR 4.32, 95% CI 2.01−8.96) were especially at risk of having significant liver fibrosis. Our study shows that people with an HBV viral load above 2000 IU/mL have a two-fold increase in the risk of liver fibrosis and may have to be considered for antiviral therapy, independent of other disease parameters.

Postmenopausal women with hepatitis B virus (HBV) infection are more likely to have accelerated liver fibrosis, eventually advancing to liver cirrhosis or hepatocellular carcinoma (HCC). The association between sex hormones and HBV-related HCC risk is unclear. We investigated whether hormone replacement therapy (HRT) is beneficial to postmenopausal women with HBV infection. This retrospective study selected the data of 44,465patients with HBV infection between January 2000 and December 2018 from Taiwan's National Health Insurance Research Database. After excluding patients with preexisting liver diseases, liver cirrhosis, or liver malignancies, we grouped the remaining 10,474 patients by whether they had undergone HRT for at least 3 months (n = 5,638) and whether they had not received HRT (n = 4,836). After propensity score matching, we assigned 3080 patients to an HRT cohort and matched them (1:1) with those in a non-HRT cohort. The incidence of HCC (P < 0.022) and all-cause mortality rate (P < 0.001) were lower in the HRT cohort than in the non-HRT cohort. The liver cirrhosis risk was not significantly higher in the HRT cohort (P = 0.355). HRT is associated with reduced HCC risk and improved survival outcomes but is unrelated to liver cirrhosis development in postmenopausal women., Competing Interests: The authors have declared that no competing interests exist.

Background: The association between chronic hepatitis B (CHB) and cardiovascular disease (CVD) remains unclear. We investigated the prevalence and risk factors of CVD in patients with CHB., Methods: Data from the Korean National Health and Nutrition Examination Surveys 2008-2011 were analyzed. Significant liver fibrosis was defined as the highest nonalcoholic fatty liver disease fibrosis score quartile, highest Forns index quintile, or fibrosis-4 ≥ 2.67. The CVD risk was calculated using the 10-year atherosclerotic cardiovascular disease (ASCVD) risk score from the 2013 ACC/AHA Guidelines., Results: Among the 506 subjects with CHB, 15 (3.0%) and 150 (29.6%) patients had a CVD history and significant liver fibrosis, respectively. Patients with CVD history were significantly older; showed a significantly higher prevalence of hypertension, metabolic syndrome, and significant liver fibrosis; and had a significantly higher platelet count, lower aspartate and alanine aminotransferase levels, higher triglyceride level, lower high-density lipoprotein level, and higher ASCVD risk than those without (all p < 0.05). In multivariate analysis, higher ASCVD risk (odds ratio [OR] = 1.090) and significant liver fibrosis (OR = 4.341) independently predicted the risk of CVD history (p < 0.05). The prevalence of CVD risk (6.7% vs. 1.4%; OR = 5.014) and high ASCVD risk (> 15%) (34.0% vs. 7.3%; OR = 6.538) was significantly higher in patients with significant liver fibrosis than in those without (all p < 0.05)., Conclusions: Significant liver fibrosis was independently associated with the risk of CVD history in patients with CHB. Prospective studies are needed to validate the longitudinal association between fibrotic burden and CVD development in patients with CHB., (© 2021.

Hepatocellular carcinoma (HCC) is a global health challenge. Due to the high prevalence in low-income countries, hepatitis B virus (HBV) and hepatitis C virus infections remain the main risk factors for HCC occurrence, despite the increasing frequencies of non-viral etiologies. In addition, hepatitis D virus coinfection increases the oncogenic risk in patients with HBV infection. The molecular processes underlying HCC development are complex and various, either independent from liver disease etiology or etiology-related. The reciprocal interlinkage among non-viral and viral risk factors, the damaged cellular microenvironment, the dysregulation of the immune system and the alteration of gut-liver-axis are known to participate in liver cancer induction and progression. Oncogenic mechanisms and pathways change throughout the natural history of viral hepatitis with the worsening of liver fibrosis. The high risk of cancer incidence in chronic viral hepatitis infected patients compared to other liver disease etiologies makes it necessary to implement a proper surveillance, both through clinical-biochemical scores and periodic ultrasound assessment. This review aims to outline viral and microenvironmental factors contributing to HCC occurrence in patients with chronic viral hepatitis and to point out the importance of surveillance programs recommended by international guidelines to promote early diagnosis of HCC., Competing Interests: Conflict-of-interest statement: The authors declare no conflict of interest., (©The Author(s) 2022.

Importance: Coexistence of hepatitis B surface antigen (HBsAg) and antibody against HBsAg (anti-HBs) constitutes an atypical serological profile in chronic hepatitis B virus infection, and the association between coexistent HBsAg and anti-HBs with severe liver fibrosis and cirrhosis in patients with chronic hepatitis B (CHB) remains unclear., Objective: To investigate the association of coexistent HBsAg and anti-HBs with severe liver fibrosis and cirrhosis in patients with CHB., Design, Setting, and Participants: Consecutive treatment-naive patients with CHB from 2 medical institutions in China were enrolled between January 10, 2015, and March 31, 2021. Severe liver fibrosis and cirrhosis were identified using the aspartate transaminase (AST) to platelet ratio index (APRI), the fibrosis index based on 4 factors (FIB-4; factors comprise age, AST level, alanine aminotransferase [ALT] level, and platelet count), transient elastography, or ultrasonography. Data were analyzed from August 1, 2021, to April 15, 2022., Main Outcomes and Measures: The primary outcomes were rates of severe liver fibrosis and cirrhosis among patients with vs patients without coexistant HBsAg and anti-HBs. Severe liver fibrosis was defined as an APRI score of 1.5 or higher, a FIB-4 score of 3.25 or higher, or a liver stiffness measurement of 8 kPa or higher; cirrhosis was defined as an APRI score of 2.0 or higher, a FIB-4 score of 6.5 or higher, a liver stiffness measurement of 11 kPa or higher, or ultrasonographic findings suggestive of cirrhosis., Results: Of 6534 enrolled patients, 4033 patients (61.7%) were male, and the median (IQR) age was 41.0 (33.0-52.0) years. A total of 277 patients (4.2%) had coexistent HBsAg and anti-HBs. Patients with vs without anti-HBs were older (median [IQR], 46.0 [33.0-55.5] years vs 41.0 [33.0-52.0] years) and had a higher proportion of hepatitis B e antigen (HBeAg) positivity (123 of 277 patients [44.4%] vs 2115 of 6257 patients [33.8%]; P < .001), higher ALT levels (median [IQR], 45.1 [24.6-119.0] U/L vs 36.7 [22.0-77.0] U/L; P = .001) and AST levels (median [IQR], 35.0 [23.5-68.4] U/L vs 28.3 [21.6-51.0] U/L; P < .001), and lower platelet counts (median [IQR], 173.0 × 103/μL [129.0-212.5 × 103/μL] vs 185.0 × 103/μL [141.0-224.0 × 103/μL]; P = .004), albumin levels (median [IQR], 4.37 [4.11-4.56] g/dL vs 4.43 [4.17-4.61] g/dL; P = .02), and HBsAg levels (median [IQR], 2.8 log10 [1.6-3.4 log10] IU/mL vs 3.3 log10 [2.6-3.9 log10] IU/mL; P < .001). Compared with patients without anti-HBs, those with anti-HBs had higher APRI scores (median [IQR], 0.5 [0.3-1.4] vs 0.4 [0.3-0.9]; P < .001), FIB-4 scores (median [IQR], 1.4 [0.9-2.6] vs 1.1 [0.7-2.1]; P < .001), and liver stiffness values (median [IQR], 7.5 [6.2-9.8] kPa vs 6.3 [5.2-8.1] kPa; P = .003). Patients with anti-HBs also had higher proportions of severe liver fibrosis (102 of 277 patients [36.8%] vs 1397 of 6207 patients [22.5%]; P < .001) and cirrhosis (87 of 277 patients [31.4%] vs 1194 of 6213 patients [19.2%]; P < .001) compared with patients without anti-HBs. The coexistence of HBsAg and anti-HBs was independently associated with severe liver fibrosis (odds ratio [OR], 2.29; 95% CI, 1.56-3.38; P < .001) and cirrhosis (OR, 1.73; 95% CI, 1.12-2.68; P = .01) in the multivariate analysis. However, the association of coexistent HBsAg and anti-HBs with cirrhosis was only observed in patients with HBeAg negativity (OR, 1.66; 95% CI, 1.05-2.62; P = .03) and not in patients with HBeAg positivity (OR, 1.45; 95% CI, 0.87-2.43; P = .16)., Conclusions and Relevance: In this cross-sectional study, the coexistence of HBsAg and anti-HBs was unusual in hepatitis B virus infection and was associated with more advanced liver diseases, such as severe liver fibrosis and cirrhosis, especially among patients with HBeAg negativity. These results suggest that close monitoring for liver fibrosis and cirrhosis is warranted in patients with CHB who have this serological profile.

Background: Quantitative data are limited on the natural course of liver fibrosis in patients with chronic HBV infection (CHB)., Aims: To estimate the prevalence of fibrosis status including non-fibrosis, significant fibrosis, advanced fibrosis, and cirrhosis throughout the natural course of CHB., Methods: We searched Cochrane library, EMBASE, PubMed, SCOPUS, Web of Science, and ScienceDirect from January 1993 to November 2019 for studies with histologic data on liver fibrosis in CHB natural course. CHB course was defined based on current criteria for identifying infection phases as recommended by international clinical practice guidelines, including the HBeAg-positive immune-tolerant, HBeAg-positive immune-active, HBeAg-negative immune-inactive, HBeAg-negative immune-reactive, and HBsAg-negative phases. Pooled prevalence rate of fibrosis status at each phase was obtained from random-effect meta-analyses., Results: Thirty-three studies with 9,377 adult participants (23.8-49.0 age years; 45.5-88.6% males) were eligible and finally included. The estimated prevalence of non-fibrosis, significant fibrosis, advanced fibrosis, and cirrhosis was, for HBeAg-positive immune-tolerant phase: 31.2% (95%CI 15.6-46.7), 16.9% (95%CI 7.8-26.1), 5.4% (95%CI 0.0-11.2), and 0.0% (95%CI 0.0-1.5); HBeAg-positive immune-active phase: 6.9% (95%CI 3.6-10.2), 50.6% (95%CI 39.2-61.9), 32.1% (95%CI 24.2-40.0), and 12.8% (95%CI 8.6-17.0); HBeAg-negative immune-inactive phase: 32.4% (95%CI 0.0-100.0), 24.8% (95%CI 4.5-45.1), 3.0% (95%CI 0.0-8.3), and 0.0% (95%CI 0.0-1.0); and HBeAg-negative immune-reactive phase: 6.3% (95%CI 3.5-9.2), 50.3% (95%CI 38.9-61.7), 30.3% (95%CI 20.9-39.6), and 10.0% (95%CI 6.6-13.5), respectively. There was only one study for HBsAg-negative phase, thus not allowing further meta-analyses., Conclusions: Fibrosis risk persists through CHB natural course. These data can support risk estimation in clinical practice and provide reference for noninvasive investigation., (© 2021.

Purpose: Entecavir (ETV) and tenofovir disoproxil fumarate (TDF) are both recommended as first-line treatments for patients with chronic hepatitis B virus (CHB) infection according to international HBV treatment guidelines. However, recent studies reported conflicting results regarding the preferred antiviral in the prevention of hepatocellular carcinoma (HCC). This cohort study aimed to investigate this issue by using Taiwan's National Health Insurance Research Database, wherein a "finite" but not life-long treatment policy was applied., Methods: From January 2008 to December 2013, a total of 12,388 consecutive adult patients with CHB who received a finite course of TDF treatment (n = 1250) or ETV treatment (n = 11,138) were analyzed through screening for study eligibility followed by the 1:4 propensity score matching method., Findings: In the entire cohort, the annual incidence and survival between the ETV and TDF groups were not significantly different regarding HCC occurrence (2.05 vs 2.74 per 100 patient-years [PY]; P = 0.055; hazard ratio [HR], 0.975; log-rank, P = 0.966), cirrhosis-related complications (1.9 vs 2.4 per 100 PY; P = 0.149; HR, 0.869; log-rank, P = 0.388), or all-cause mortality (2.16 vs 1.6 per 100 PY; P = 0.119; HR, 0.831; log-rank, P = 0.342), respectively. Propensity score matching analyses yielded similar results regarding HCC occurrence, cirrhosis-related complications, and all-cause mortality. In addition, these findings were consistently reproduced in the subgroups of patients with chronic hepatitis and cirrhosis that developed before antiviral treatment., Implications: ETV and TDF did not significantly differ in prevention of HCC occurrence or reduction of cirrhosis-related complications and all-cause mortality in patients with CHB receiving a finite period of treatment., (Copyright © 2022 Elsevier Inc.
