[PMID: 38700381 DOI: 10.1111/liv.15959] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/21/2023] [Revised: 02/06/2024] [Accepted: 04/18/2024] [Indexed: 05/05/2024]
Abstract
BACKGROUND AND AIMS Hepatitis B virus (HBV) vaccination programs in Taiwan are one of the earliest programs in the world and have largely reduced the prevalence of HBV infection. We aimed to demonstrate the vaccination efficacy after 35 years and identify gaps toward HBV elimination. METHODS A total of 4717 individuals aged 1-60 years were recruited from four administrative regions based on the proportion of population distribution. Serum levels of hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (anti-HBs), and hepatitis B core antibody (anti-HBc) levels were assessed. HBV viral load, genotypes and HBsAg 'ɑ' determinant variants were evaluated if indicated. RESULTS After 35 years of vaccination, the overall seropositivity rates for HBsAg and anti-HBc in Taiwan were 4.05% and 21.3%, respectively. The vaccinated birth cohorts exhibited significantly lower seropositivity rates for both markers compared to the unvaccinated birth cohorts (HBsAg: 0.64% vs. 9.78%; anti-HBc: 2.1% vs. 53.55%, respectively; p < 0.0001). Maternal transmission was identified as the main route of HBV infection in breakthrough cases. Additionally, increased prevalences of genotype C and HBsAg escape mutants were observed. CONCLUSION The 35-year universal HBV vaccination program effectively reduced the burden of HBV infection, but complete eradication of HBV infection has not yet been achieved. In addition to immunization, comprehensive screening and antiviral therapy for infected individuals, especially for pregnant women, are crucial strategies to eliminate HBV.

[PMID: 37970568 PMCID: PMC10642378 DOI: 10.5501/wjv.v12.i4.233] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/21/2023] [Revised: 07/19/2023] [Accepted: 08/07/2023] [Indexed: 09/19/2023] Open
Abstract
BACKGROUND Hepatitis B virus (HBV) and hepatitis C virus (HCV) viral load (VL) estimation is essential for the management of both HBV and HCV infections. Due to a longer turnaround time for VL estimation, many patients drop out from the cascade of care. To achieve the global goals of reducing morbidity and mortality due to HBV/HCV and moving towards their elimination by 2030, molecular diagnostic platforms with faster and random (i.e. single sample) access are needed. AIM To evaluate the performance of the recently launched NeuMoDx 96 random access system with the conventional COBAS®AmpliPrep/COBAS TaqMan system for HBV and HCV VL estimation. METHODS Archived once-thawed plasma samples were retrieved and tested on both platforms. Correlation between the assays was determined by linear regression and Bland-Altman analysis. The study included samples from 186 patients, 99 for HBV of which 49 were true infected HBV cases (hepatitis B surface antigen, anti-hepatitis B core antibody, and HBV DNA-positive) and 87 for HCV assay in which 39 were true positives for HCV infection (anti-HCV and HCV RNA-positive). RESULTS The median VL detected by NeuMoDx for HBV was 2.9 (interquartile range [IQR]: 2.0-4.3) log10 IU/mL and by COBAS it was 3.70 (IQR: 2.28-4.56) log10 IU/mL, with excellent correlation (R2 = 0.98). In HCV, the median VL detected by NeuMoDx was 4.9 (IQR: 4.2-5.4) log10 IU/mL and by COBAS it was 5.10 (IQR: 4.07-5.80) log10 IU/mL with good correlation (R2 = 0.96). CONCLUSION The overall concordance between both the systems was 100% for both HBV and HCV VL estimation. Moreover, no genotype-specific bias for HBV/HCV VL quantification was seen in both the systems. Our findings reveal that NeuMoDx HBV and HCV quantitative assays have shown overall good clinical performance and provide faster results with 100% sensitivity and specificity compared to the COBAS AmpliPrep/COBAS TaqMan system.

[PMID: 37426446 PMCID: PMC10327564 DOI: 10.3389/fneur.2023.1203679] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2023] [Accepted: 05/30/2023] [Indexed: 07/11/2023] Open
Abstract
Background The prevalence of myasthenia gravis is increasing in many countries, including Asia. As treatment options expand, population-based information about the disease burden can inform health technology assessments. Methods We conducted a population-based retrospective cohort study using the Taiwan National Healthcare Insurance Research database and Death Registry to describe the epidemiology, disease burden and treatment patterns of generalized myasthenia gravis (gMG) from 2009 to 2019. Episodes of hepatitis B virus (HBV) infection or reactivation were explored. Results The number of patients with gMG increased from 1,576 in 2009 to 2,638 in 2019 and the mean (standard deviation) age from 51.63 (17.32) to 55.38 (16.29) years. The female:male ratio was 1.3:1. Frequently reported co-morbidities were hypertension (32-34% of patients), diabetes mellitus (16-21%) and malignancies (12-17%). The prevalence of patients with gMG increased annually from 6.83/100,000 population in 2009 to 11.18/100,000 population in 2019 (p < 0.0001). There was no temporal trend in all-cause fatality rates (range 2.76-3.79/100 patients annually) or gMG incidence rates (2.4-3.17/100,000 population annually). First-line treatment was with pyridostigmine (82%), steroids (58%), and azathioprine (11%). There was minimal change in treatment patterns over time. Among 147 new HBV infections, 32 (22%) received ≥4 weeks of antiviral therapy suggesting chronic infection. The HBV reactivation rate was 7.2%. Conclusion The epidemiology of gMG in Taiwan is evolving rapidly, with higher prevalence rates and increasing involvement of older age-groups suggesting a growing burden of disease and associated healthcare costs. HBV infection or reactivation may pose a previously unrecognized recognized risk for patients with gMG receiving immunosuppressants.

Abstract
Hepatocellular carcinoma (HCC) remains a global health challenge, causing 600,000 deaths each year. Infectious factors, including hepatitis B virus (HBV), hepatitis C virus (HCV) and hepatitis D virus (HDV), have long been considered the major risk factors for the development and progression of HCC. These pathogens induce hepatocyte transformation through a variety of mechanisms, including insertional mutations caused by viral gene integration, epigenetic changes, and the induction of long-term immune dysfunction. The discovery of these mechanisms, while advancing our understanding of the disease, also provides targets for new diagnostic and therapeutic approaches. In addition, the discovery and research of chronic HEV infection over the past decade indicate that this common hepatitis virus also seems to have the potential to induce HCC. In this review, we provide an overview of recent studies on the link between hepatitis virus and HCC, as well as new diagnostic and therapeutic approaches to HCC based on these findings. Finally, we also discuss the potential relationship between HEV and HCC. In conclusion, these associations will further optimize the diagnosis and treatment of infection-associated HCC and call for better management policies.

Hepatitis B burden and population immunity in a high endemicity city - a geographically random household epidemiology study for evaluating achievability of elimination. Epidemiol Infect 2023; 151:e22.

Abstract
This study aimed to provide reference for evaluating the achievability of hepatitis B virus (HBV) elimination in a high endemicity city with universal neonatal vaccination in place for over 30 years. Between September 2018 and October 2020, 2085 citizens from 1143 geographically random households in Hong Kong completed a questionnaire and had blood-testing for HBV markers (anti-HBs, HBsAg, anti-HBc, HBeAg). We evaluated the epidemiology and examined factors associated with HBV exposure, vaccination and chronic diseases. The proportion of households with HBsAg positive index participants was 9.2% (95% CI 7.5%-10.9%). The age- and sex-adjusted HBsAg prevalence was 6.3% (95% CI 5.3%-7.4%), compared to >10% in those born in 1960-1970 and among non-local born citizens, and <1% in people born after introduction of neonatal vaccination. Among 155 HBsAg positive participants, 59% were aware of their infection status with 10% on treatment and 10/150 (6.7%) HBeAg positive. More than 40% (872/2064) tested negative for both HBsAg and anti-HBs, contributed by the lack of immunity in older adults and the waning immunity of vaccines. Hong Kong has remained at high-intermediate HBV endemicity state. The moderate level of anti-HBs positivity and very low treatment coverage (10%) among HBsAg positive participants pose challenges for achieving the HBV elimination target.

The Impact of b/tsDMARD Dose Reduction on Chronic Hepatitis B in Rheumatoid Arthritis Patients: A Two-Center Long-Term Safety Analysis. J Clin Med 2022; 12:jcm12010086. [PMID: 36614890 PMCID: PMC9821696 DOI: 10.3390/jcm12010086] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2022] [Revised: 12/11/2022] [Accepted: 12/12/2022] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND We aimed to investigate the change of hepatitis B virus (HBV) viral loads and HBV reactivation (HBVr) in rheumatoid arthritis (RA) patients after tapering the dose of biological/targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs). METHODS This two-center analysis retrospectively investigated the virological and biochemical evidence of HBVr in RA patients who underwent b/tsDMARD dose reduction. Serum levels of viral loads were determined using real-time PCR. Serum levels of alanine transaminase (ALT) were determined using spectrophotometry. RESULTS Among a total of 40 HBsAg+ RA patients who tapered b/tsDMARDs, 14 (35%) used tocilizumab; 12 (30%) used tumor necrosis factor (TNF)-α inhibitors; and the rest used either abatacept or tofacitinib. We found that patients who had detectable HBV DNA before tapering achieved a one-log reduction in HBV DNA levels, in contrast to the findings in the other 12 patients who did not taper b/tsDMARDs (no change in HBV DNA levels with time). The incidence of HBVr (increased viral loads with hepatitis) was 4.62 (95%CI: 2.08, 10.28) and 2.26 (95%CI: 0.56, 9.02) events per 100 person-years before and after b/tsDMARD tapering, respectively. CONCLUSIONS The HBV viral load decreased after the tapering of b/tsDMARDs in RA patients with detectable HBV DNA. Dose reduction in b/tsDMARDs might be beneficial.

Abstract
BACKGROUND Hepatitis B virus (HBV) affects the occurrence and survival outcome of various malignant disorders. The study aimed to evaluate the survival outcome of head and neck squamous cell cancer (HNSCC) patients with or without HBV infection. METHODS This study included patients with HNSCC who visited Taichung Veterans General Hospital from 2007 to 2015. HBV infection was defined by hepatitis B surface antigen (HBsAg) seropositivity. By propensity score matching, we compared survival outcomes, including progression-free survival (PFS) and overall survival (OS), among patients with or without HBV infection. RESULTS The prevalence of HBV infection in our cohort was 12.3%. Among the 1,015 patients included in the matched analysis, a higher risk of baseline liver cirrhosis (11.3% vs. 3.4%, p < 0.001) and initial hepatic dysfunction (10.8% vs. 5.4%, p = 0.005) rates were observed than those without HBV infection at baseline. The 5-year OS was 43.1% and 53.2% (p < 0.001) and the 5-year PFS was 37.4% and 42.3% (p = 0.007) in patients with and without HBV infection, respectively. The incidence of subsequent hepatic dysfunction showed no difference between patients with and without HBV infection (29.6% vs. 26.8%, p = 0.439). CONCLUSIONS Patients with HNSCC and HBV infection were younger and had a higher risk of cirrhosis compared to those without HBV infection. Moreover, HBV infection significantly influenced the OS and PFS outcomes but not subsequent hepatic dysfunction in patients with HNSCC.

Abstract
BACKGROUND The association between non-alcoholic fatty liver disease and hepatitis B virus (HBV) infection is inconclusive. The aim of this study was to investigate the viral dynamic of HBV and its association with change of body mass index (BMI), aspartate transaminase (AST), and alanine transaminase (ALT) levels after bariatric surgery. METHODS Patients who underwent bariatric surgery between June 2011 and May 2014 were selected in this retrospective study. BMI, AST, ALT, and HBV DNA levels were calculated pre-operatively and at 1st, 3rd, and 6th postoperative months. RESULTS Two hundred and seventy-nine patients including 34 (12.2%) HBsAg-positive and 245 (87.8%) HBsAg-negative patients were enrolled. Eighteen HBsAg-positive and HBeAg-negative patients were matched with 36 HBsAg-negative patients. A significant decrease in BMI was found since 1st postoperative month in both groups. AST and ALT increased at 1st postoperative month, but decreased at 3rd and 6th postoperative months in both groups. However, a significant increase in HBV DNA level was observed in HBeAg-negative patients since 1st postoperative month with the highest peak at 3rd postoperative month. HBV reactivation occurred in 4 out of 17 (23.5%) patients, 8 out of 16 (50.0%) patients, and 4 out of 12 (33.3%) patients at 1st, 3rd, and 6th postoperative months, respectively. The change of HBV DNA was not associated with change of BMI, AST, or ALT after bariatric surgery. CONCLUSION Bariatric surgery can achieve significant weight loss and improvement of liver function tests. However, there existed significant risk of HBV reactivation after bariatric surgery for patients with obesity.

[PMID: 35738290 PMCID: PMC9349325 DOI: 10.1016/s2468-1253(22)00124-8] [Citation(s) in RCA: 201] [Impact Index Per Article: 100.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2021] [Revised: 04/02/2022] [Accepted: 04/04/2022] [Indexed: 12/23/2022]
Abstract
Background Combating viral hepatitis is part of the UN Sustainable Development Goals (SDGs), and WHO has put forth hepatitis B elimination targets in its Global Health Sector Strategy on Viral Hepatitis (WHO-GHSS) and Interim Guidance for Country Validation of Viral Hepatitis Elimination (WHO Interim Guidance). We estimated the global, regional, and national prevalence of hepatitis B virus (HBV), as well as mortality and disability-adjusted life-years (DALYs) due to HBV, as part of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019. This included estimates for 194 WHO member states, for which we compared our estimates to WHO elimination targets. Methods The primary data sources were population-based serosurveys, claims and hospital discharges, cancer registries, vital registration systems, and published case series. We estimated chronic HBV infection and the burden of HBV-related diseases, defined as an aggregate of cirrhosis due to hepatitis B, liver cancer due to hepatitis B, and acute hepatitis B. We used DisMod-MR 2.1, a Bayesian mixed-effects meta-regression tool, to estimate the prevalence of chronic HBV infection, cirrhosis, and aetiological proportions of cirrhosis. We used mortality-to-incidence ratios modelled with spatiotemporal Gaussian process regression to estimate the incidence of liver cancer. We used the Cause of Death Ensemble modelling (CODEm) model, a tool that selects models and covariates on the basis of out-of-sample performance, to estimate mortality due to cirrhosis, liver cancer, and acute hepatitis B. Findings In 2019, the estimated global, all-age prevalence of chronic HBV infection was 4·1% (95% uncertainty interval [UI] 3·7 to 4·5), corresponding to 316 million (284 to 351) infected people. There was a 31·3% (29·0 to 33·9) decline in all-age prevalence between 1990 and 2019, with a more marked decline of 76·8% (76·2 to 77·5) in prevalence in children younger than 5 years. HBV-related diseases resulted in 555 000 global deaths (487 000 to 630 000) in 2019. The number of HBV-related deaths increased between 1990 and 2019 (by 5·9% [–5·6 to 19·2]) and between 2015 and 2019 (by 2·9% [–5·9 to 11·3]). By contrast, all-age and age-standardised death rates due to HBV-related diseases decreased during these periods. We compared estimates for 2019 in 194 WHO locations to WHO-GHSS 2020 targets, and found that four countries achieved a 10% reduction in deaths, 15 countries achieved a 30% reduction in new cases, and 147 countries achieved a 1% prevalence in children younger than 5 years. As of 2019, 68 of 194 countries had already achieved the 2030 target proposed in WHO Interim Guidance of an all-age HBV-related death rate of four per 100 000. Interpretation The prevalence of chronic HBV infection declined over time, particularly in children younger than 5 years, since the introduction of hepatitis B vaccination. HBV-related death rates also decreased, but HBV-related death counts increased as a result of population growth, ageing, and cohort effects. By 2019, many countries had met the interim seroprevalence target for children younger than 5 years, but few countries had met the WHO-GHSS interim targets for deaths and new cases. Progress according to all indicators must be accelerated to meet 2030 targets, and there are marked disparities in burden and progress across the world. HBV interventions, such as vaccination, testing, and treatment, must be strategically supported and scaled up to achieve elimination. Funding Bill & Melinda Gates Foundation.

Genetic variants of NTCP gene and hepatitis B vaccine failure in Taiwanese children of hepatitis B e antigen positive mothers. Hepatol Int 2022; 16:789-798. [PMID: 35635688 DOI: 10.1007/s12072-022-10350-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/22/2022] [Accepted: 04/25/2022] [Indexed: 11/04/2022]
Abstract
BACKGROUND AND AIMS Hepatitis B virus (HBV) vaccine failure remains a hurdle to the global elimination of HBV infections in the vaccination era. We aimed to elucidate the relationships between HBV entry receptor sodium taurocholate co-transporting polypeptide (NTCP) and vaccine failure in children born to highly infectious mothers. METHODS The genetic variants rs7154439, rs4646285, rs4646287, and rs2296651 were genotyped in 170 children with chronic HBV infections and 138 control children of mothers positive for hepatitis B e antigen (HBeAg). All children received hepatitis B immunoglobulin and complete HBV vaccination. Total RNAs from 82 adult non-tumor liver tissues were quantified for NTCP, type I interferons and interferon-induced transmembrane protein 3 (IFITM3) levels. RESULTS A higher rate of the GA/AA genotype (28.3% vs. 15.3%, p = 0.006) of the genetic variant rs4646287 in intron 1 of the NTCP gene was detected in control children compared to the carrier children. The rs4646287 G > A genotype was associated with younger ages at which spontaneous HBeAg seroconversion occurred (10.8 ± 8.4 vs. 14.6 ± 8.7 years, p = 0.003) in chronic HBV-infected children. Unique correlation patterns of NTCP and innate immunity-related genes (type I interferons and IFITM3) were found in HBV-infected liver tissues with the rs4646287 G > A genotype. CONCLUSION The rs4646287 G > A genotype of the NTCP gene may be associated with lower risk for HBV vaccine failure in children born to highly infectious mothers. The protective effect of rs4646287 G > A was also present in carrier children, evidenced by earlier spontaneous HBeAg seroconversion.

No Evidence for a Causal Link between Serum Uric Acid and Nonalcoholic Fatty Liver Disease from the Dongfeng-Tongji Cohort Study. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2022; 2022:6687626. [PMID: 35340212 PMCID: PMC8941576 DOI: 10.1155/2022/6687626] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/14/2020] [Revised: 11/27/2021] [Accepted: 02/02/2022] [Indexed: 11/20/2022]
Abstract
Background and Aims Elevated serum uric acid (SUA) is associated with an increased risk of nonalcoholic fatty liver disease (NAFLD); however, whether this association is causal is undetermined. Methods Each participant from the Dongfeng-Tongji cohort study based on 27,009 retirees was interviewed face-to-face following a clinical examination. Covariance, logistic regression analysis, and instrumental variables were used to assess associations between SUA and (severity of) NAFLD and the causal link. Results Among 8,429 subjects free of NAFLD at baseline, 2,007 participants developed NAFLD after 5 years of follow-up. The multivariable-adjusted odds ratio (OR) for NAFLD for individuals in the fourth quartile of SUA level versus those in the first was 1.71 (95% CI: 1.45-2.01, P for trend <0.001) and was more dramatic in women or normal-weight persons. Furthermore, SUA was materially associated with greater mean markers of hepatic necroinflammation and greater probabilities of fibrosis. In genetic analyses, both single nucleotide polymorphisms (rs11722228 to SLC2A9 and rs2231142 to ABCG2) were pronouncedly associated with increased SUA concentrations, ranging from 0.19 to 0.22 mg/dl. No significant associations were observed between SNPs and potential confounders. No association was observed between the SUA-increasing allele and NAFLD, with an OR of 0.98 (95% CI: 0.90-1.08) per genetic score. This was not significantly different (P = 0.25) from what was expected (1.03, 95% CI: 1.03-1.03). Conclusions SUA was positively associated with NAFLD incidence especially in female and normal-weight individuals and the suspected progression risk of newly developed NAFLD. However, the Mendelian randomization analyses lend no causal evidence, suggesting high SUA as a marker and not a cause of NAFLD.

Abstract
Complete disease journey and risk factors for poor outcomes are needed to facilitate effectiveness evaluations of new therapies and clinical decision-making in B-cell Non-Hodgkin lymphoma (B-NHL), particularly in Asia where such data are lacking. This retrospective cohort study used electronic medical records from a regional medical centre in southern Taiwan to follow-up 441 patients newly diagnosed with common B-NHL subtypes: Diffuse Large B-cell Lymphoma (DLBCL), Follicular Lymphoma (FL), Chronic Lymphocytic Leukaemia/Small Lymphocytic Lymphoma (CLL/SLL), Marginal Zone Lymphoma (MZL), Mantle Cell Lymphoma (MCL), and Waldenström macroglobulinemia (WM), between 01-Jan-2008 and 31-Dec-2013, until 31-Dec-2017. Treatment pathways were modelled using a Markov approach. Stage III/IV disease at diagnosis was frequent for patients with DLBCL, FL, MCL and WM. Hepatitis B surface antigen/hepatitis C virus seropositivity was 18.6%/12.3%. Clinical responses to 1st-line treatment were observed in 76.0% (DLBCL), 87.3% (FL), 86.0% (MZL), 60.0% (MCL), and 42.9% (WM) of patients. For DLBCL, disease control was achieved by ~ 50% after 1st-line, ~ 24% after 2nd-line, ~ 17% after 3rd-line. Patients with Stage III/IV DLBCL or age > 65 years at diagnosis had lower rates of active treatment, poorer disease control and higher mortality than patients with early stage disease or age ≤ 65 years. Disease flare < 6 months after 1st-line treatment was significantly associated with mortality. Despite good clinical response rates for some sub-types, survival remains poor. New treatments are needed to improve the outcome of B-NHL.

Clin Microbiol Infect 2021; 27:1693.e9-1693.e15. [PMID: 33677082 DOI: 10.1016/j.cmi.2021.02.023] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2020] [Revised: 02/22/2021] [Accepted: 02/24/2021] [Indexed: 01/24/2023]
Abstract
OBJECTIVE Monitoring of viral loads (VL) for hepatitis B and C viruses (HBV; HCV) is essential to evaluate disease progression and treatment response. Automated, random-access rapid systems are becoming standard to provide clinicians with reliable VL. The aim of this study was to evaluate the analytical performances of the recently launched NeuMoDx™ for HBV-DNA and HCV-RNA quantification. METHODS Clinical samples routinely quantified on the Beckman-Veris system were either retrospectively (frozen samples; HBV n = 178, HCV n = 249), or in parallel (fresh primary tubes; HBV n = 103, HCV n = 117) tested using NeuMoDx™. Linearity range was assessed on serial dilutions of high-titre plasmas containing different genotypes for HBV (A-E, n = 9) and HCV (1a,1b,2-5, n = 12). RESULTS Overall test failure, mostly internal control amplification failure, was 2.3% and was not influenced by matrix types (fresh or frozen). For HBV VL, κ agreement was 74%, with 27 (12.6%) discrepancies. Correlation between HBV assays on 72 quantified samples by both methods was excellent (r = 0.963) with a mean bias (NeuMoDx™-Veris) of 0.21 log IU/mL. For HCV VL, κ agreement reached 94%, with 9 (2.8%) discrepancies. The r correlation factor between assays on 104 samples was 0.960 with a mean bias of -0.14 log IU/mL (NeuMoDx™-Veris). Serial dilutions confirmed the claimed linear ranges for all analysed HBV and HCV genotypes. The mean turnaround time was 72 minutes (range 55-101 minutes) for HBV and 96 minutes (range 78-133 minutes) for HCV. CONCLUSION Results obtained on the NeuMoDx™ confirmed the overall good functionality of the system with a short turn-around-time, full traceability and easy handling. These results on HBV and HCV VL look promising and should be challenged with further comparisons.

Abstract
Chronic hepatitis B (CHB) remains a global healthcare burden. Although the recent developments in the field have led to a reduction in incidence, the morbidity and mortality including liver cirrhosis and hepatocellular carcinoma (HCC) remain a formidable challenge. Advances in understanding the immunopathogenesis of CHB have led to a recent change in clinical categorization. EASL introduced the term hepatitis B 'e' antigen (HBeAg)-negative chronic infection, to replace the historical term 'inactive carrier' disease phase, the commonest CHB phase. Although this disease phase is associated with a favorable prognosis, it is not a truly 'inactive' disease phase with no ostensible liver disease, as inferred by the previous anachronistic terminology, and the risk of spontaneous reactivation and the potential risk of disease progression and HCC development are not negligible. Likewise, the APASL also uses the term "Incidentally Detected Asymptomatic Hepatitis B surface antigen (HBsAg)-positive Subject (IDAHS)", comprising all HBsAg-positive subjects who are incidentally detected during routine tests, without any previous or present symptoms of liver disease. This entity includes HBV infection with varied stages of liver disease. Antiviral treatment is generally reserved for patients with active inflammation and/or at risk of disease progression and HCC development. HBsAg loss is considered an optimal treatment endpoint, and may also be achievable in HBeAg-negative chronic infection and IDAHS. In light of this, and the emerging novel HBV therapies, lowering the treatment threshold and a 'Treat All' approach should now be considered. In this review, we summarize the literature and guidance on HBeAg-negative chronic infection, and we make a concerted effort to present the reasons why the one-dimensional term 'inactive carrier' should be abandoned.

Abstract
BACKGROUND AND AIM Tenofovir disoproxil fumarate (TDF) and entecavir are effective antiviral medications that are recommended as first-line monotherapies for the treatment of chronic hepatitis B (CHB) infection, including decompensated liver cirrhosis with ascites. Acute kidney injury (AKI) commonly occurs in patients with cirrhosis and ascites. The aim of this study was to compare the development of AKI during TDF and entecavir treatment of CHB patients with cirrhotic refractory ascites. METHODS From January 2011 to April 2017, we identified patients who were diagnosed with cirrhosis with refractory ascites and received TDF or entecavir treatments at Kaohsiung Chang Gung Memorial Hospital. AKI was defined as an increase in serum creatinine of more than 0.3 mg/dL or 1.5-fold from baseline. All episodes of AKI were recorded and compared between those who received TDF and entecavir. RESULTS A total of 111 patients were enrolled in this retrospective study, of which 22 patients were treated with TDF and 89 were treated with entecavir. Patients with AKI episodes had a higher proportion of TDF treatment (P = 0.01), male (P = 0.023), hepatocellular carcinoma (P = 0.007), admission (P = 0.045), and mortality (P = 0.018). Logistic regression analysis illustrated that TDF treatment of patients with comorbidity was an independent risk factor for the development of AKI [odds ratio (OR), 3.756; 95% confidence interval (CI), 1.293-10.912; P = 0.015] and hepatorenal syndrome (OR, 7.651; 95% CI, 1.697-34.508; P = 0.008). CONCLUSIONS TDF treatment is a risk factor for AKI and HRS development in cirrhotic patients with refractory ascites in comparison with entecavir treatment, especially in patients with comorbidity.

Abstract
Background Long-term monotherapy with nucleos(t)ide analogs (NAs) represents the treatment option for the majority of patients with chronic hepatitis B (CHB), an aging population with a greater likelihood of comorbidities. We assessed the prevalence of concurrent non-hepatic diseases and the safety monitoring in a large cohort of CHB patients receiving NAs and their potential impact on disease outcomes. Methods We included 500 consecutive CHB patients from 5 major tertiary Greek centers, under long-term therapy with an NA. Epidemiological/clinical characteristics and data on concomitant disease, drug use and investigations ordered were collected. Results The mean age was 58 years and 66% were male. Most patients were receiving tenofovir disoproxil fumarate (TDF, 60%) or entecavir (ETV, 37%) monotherapy. Decompensated cirrhosis at baseline was present in 10%, while hepatocellular carcinoma (HCC) under therapy developed in 21 patients. The median duration of total NA therapy was 56 and of latest therapy 42 months. The most common (prevalence >10%) comorbidities were hypertension (28%), non-HCC cancer(s) (12%), and diabetes (11%). Patients with a longer duration of latest therapy (≥4 vs. <4 years) were older (mean age: 58 vs. 56 years, P=0.004), had more frequent history of prior use of NA(s) (53% vs. 35%, P<0.001), and less frequent liver decompensation (5% vs. 13%, P=0.008) and non-HCC cancers (8% vs. 15%, P=0.020). HCC developed more frequently in patients with than in those without diabetes (11% vs. 3%, P=0.022). Conclusion Greek CHB patients currently treated with NAs, almost exclusively ETV or TDF, are often older than 60 years, have several comorbidities, and thus require careful management.

Abstract
Hepatitis B Virus (HBV) chronic infection contributes to a high risk of hepatocellular cancer (HCC) development. HBV is a strong cancer inducer, due to natural history of infection, virological characteristics and viral DNA integrations events in host genome. Prolonged infection and high viral loads, particularly frequent in patients infected in childhood, are risk factors of HCC development for patients with HBV chronic infection. A HBV vaccine, based on immunization against the surface protein HBs, showed a strong efficacy to prevent chronic HBV infection. The development of universal neonatal vaccination programmes contributed to the decrease of HBV chronic infection incidence in children of high endemic areas. Although HBs antibodies levels diminished years after vaccination, HBV neonatal vaccination programmes led to a lower incidence of chronic HBV infection among young adults. The decrease of HBV chronic infection incidence was associated to a reduction of HCC incidence in children and young adults from areas with a high prevalence of HBV infection.

Abstract
Objective This study was performed to clarify the influence of nonalcoholic fatty liver disease (NAFLD) on liver stiffness measurement (LSM) and establish a new diagnostic model. Methods A retrospective cohort of 601 patients with chronic hepatitis B (CHB) was enrolled as the derivation group, and a prospective cohort of 30 patients with concurrent CHB and NAFLD was enrolled as the validation group. Results The area under the receiver operating characteristic curve of LSM in patients with CHB without NAFLD (0.792) was higher than that in patients with concurrent CHB and NAFLD (0.720) in diagnosing significant liver fibrosis. Patients with concurrent CHB and NAFLD had significantly higher LSM values than those without NAFLD among the overall F0-F1 patients (6.88 vs. 5.80). The LSM value in the higher controlled attenuation parameter (CAP) quartile was significantly higher than that in the normal CAP quartile among F0-F1 patients (6.80 vs. 5.74). The efficacy of our new diagnostic model for liver fibrosis (Fibro-NAFLD) was higher than that of LSM in both study groups. Conclusion NAFLD with a high CAP value increases the risk of false-positive diagnosis of significant fibrosis. The Fibro-NAFLD model improves the diagnostic efficacy of LSM in patients with concurrent CHB and NAFLD.

Abstract
OBJECTIVES We estimated the impact of universal hepatitis B immunization using 18-year data of women who are of childbearing age in South Korea. METHODS We used hepatitis B surface antigen (HBsAg) and antibody (anti-HBs) data of 145,993 women aged 20-49 years during 2001-2018 at the Gangnam CHA Medical Center. Annual prevalences of HBsAg and anti-HBs positivity were calculated and tested for linear trend. We conducted age-period-cohort (APC) analysis to obtain period and cohort effect. RESULTS Overall proportion of HBsAg positivity was 3.5% (n = 5050) and anti-HBs positivity was 75.3% (n = 109,907) during the study period. HBsAg positivity percentage decreased from 5.1% in 2001 to 2.5% in 2018 (P < 0.001) while anti-HBs positivity increased from 59.9% to 75.8% (P = 0.002). Average annual percent change of HBsAg positivity was -5.9% (95% confidence interval (CI): -6.9%, -4.8%). The period and cohort RR curve identified a consistent decrease in HBsAg positivity over time and across generations. CONCLUSIONS We observed a concurrent decrease in HBsAg and an increase in anti-HBs seropositivity among Korean women of childbearing age, implicating success in preventing vertical transmission.

Abstract
BACKGROUND Data from the USA suggest that chronic hepatitis B (CHB) patients have aged in the past decade. However, the burden of nonliver comorbidities has not been well characterized in Taiwan, where CHB is very prevalent. AIM Our study examined this issue as it presented between 2001 and 2011 in Taiwan. METHODS This study identified adult patients (≥18 years) who were diagnosed with CHB in 2001, 2006, and 2011, from the Taiwan National Health Insurance Research Database (NHIRD). Changes in demographic characteristics, prevalence of nonliver comorbidities, and medication usage over the decade were examined. Non-CHB controls were adults without CHB diagnosis from the Longitudinal Health Insurance Database 2000 (LHID2000). RESULTS A total of 102,158, 252,809, and 338,200 eligible patients were identified in 2001, 2006, and 2011, respectively. The mean age significantly advanced from 45.4 to 52.3 years over the decade (p < 0.001). The prevalence of comorbidities, including diabetes mellitus, hypertension, stroke, chronic kidney disease, and bone fracture, significantly increased between 2001 and 2011 (all p < 0.001), as so were medication usage (all p < 0.001). Moreover, within each study period, compared to non-CHB controls, CHB patients were also older and more likely to have metabolic and cardiovascular comorbidities (all p < 0.001). In addition, the annual nonliver mortality in the CHB population significantly increased from 2001 to 2011. CONCLUSIONS Over a decade, the CHB population in Taiwan has aged with a higher nonliver comorbidity burden and increasing nonliver mortality. These findings may provide information to care providers in the monitoring and management of CHB patients.

Abstract
A combination of pegylated interferon-alpha (peg-IFN-α) and nucleos(t)ides analogue (NA) therapy can effectively reduce hepatitis B surface antigen (HBsAg), especially in NA-experienced chronic hepatitis B (CHB) patients. However, the immune mechanism of this therapy is unclear. Forty NA-experienced CHB patients were enrolled into this study. The frequencies of peripheral blood natural killer (NK) cells, dendritic cells (DCs), CD4+ T cells, CD8+ T cells, T helper (Th) cells, regulatory T cells (Treg ), B cells and follicular T helper (Tfh) cells were evaluated by flow cytometry. Seven of the 40 patients converted to peg-IFN-α combined with NA treatment, while the other 33 continued to NA therapy. The decrease in HBsAg was more pronounced in the combination treatment group, and only patients receiving combination treatment achieved HBsAg loss. The frequency and absolute number of CD56bright NK cells in the combination treatment group increased significantly compared with the NA treatment group, whereas the CD56dim NK cells were decreased. In the NA treatment group, the proportions of CD4+ TN , CD8+ TN , CD19+ B and cytotoxic T lymphocyte antigen-4 (CTLA-4)+ CD4+ T cells were increased, while the proportions of CD4+ TEM , CD8+ TEM , CD25+ CD4+ Treg , CD25high CD4+ Treg , CD127low CD25+ Treg , programmed cell death 1 (PD-1)+ CD4+ T, PD-1+ CD8+ T, CTLA-4+ CD8+ T, CCR4+ CD25+ Treg and CCR4+ CD25high Treg cells were decreased after therapy. For NA-experienced CHB patients who achieved low HBsAg levels, combination treatment is more likely to result in HBsAg decline and HBsAg clearance by increasing the activity of CD56bright NK cells.

HEV superinfection accelerates disease progression in patients with chronic HBV infection and increases mortality in those with cirrhosis. J Hepatol 2020; 72:1105-1111. [PMID: 32006586 DOI: 10.1016/j.jhep.2020.01.012] [Citation(s) in RCA: 34] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/24/2019] [Revised: 12/27/2019] [Accepted: 01/06/2020] [Indexed: 02/08/2023]
Abstract
BACKGROUND & AIMS Acute HEV infection causes varying degrees of liver damage. Although liver-related death due to HEV infection alone is rare in healthy individuals, it is unclear whether HEV superinfection is associated with worse outcomes in patients with chronic HBV infection. Thus, we explored whether HEV superinfection was associated with increased incidence of liver-related death, cirrhosis, and hepatocellular carcinoma (HCC). METHODS Serum and data were collected from 2 independent retrospective cohorts of patients with chronic HBV infection, comprising 2,123 patients without cirrhosis and 414 with cirrhosis at baseline, respectively. All the patients were negative for HEV-IgG at enrolment and HEV superinfection was defined by the presence of HEV-IgG seroconversion. RESULTS In the non-cirrhotic cohort, 46 of 2,123 patients developed HEV superinfection. Though HEV superinfection was only associated with increased incidence of liver-related death in the overall cohort, it was a risk factor for all 3 endpoints (liver-related death, cirrhosis, and HCC) in a subgroup of 723 HBeAg-negative patients with chronic HBV infection. In addition, the 1-year mortality rate after HEV superinfection was higher in 4 patients who developed cirrhosis during the follow-up than in those who did not (50% vs. 2.4%, p = 0.001). To elucidate the perceived relationship between HEV superinfection and risk of mortality, an independent cohort of cirrhotic patients (n = 414) was further analyzed to control for the inherent increase in mortality risk due to cirrhosis. The 10 cirrhotic patients with HEV superinfection had a higher 1-year mortality rate than those without (30% vs. 0%, p <0.001). CONCLUSIONS In both cohorts of patients with chronic HBV infection, acute HEV superinfection increases the risk of liver-related death, especially in those with cirrhosis. LAY SUMMARY The mortality caused by acute hepatitis E virus infection is usually low in the healthy population, but it is unclear how it affects patients with chronic hepatitis B virus infection, as they already have compromised liver function. Our data show that the 1-year mortality rate is 35.7% in patients with hepatitis B-related cirrhosis who contract hepatitis E virus. Hepatitis E may accelerate disease progression in patients with chronic hepatitis B.

Abstract
BACKGROUND Viral hepatitis epidemiological data are important for the World Health Organization plan of eliminating viral hepatitis. We aimed to document the prevalence of viral hepatitis A to E in Hong Kong. METHODS This community-based study was open to all Hong Kong Chinese citizens aged ≥18 years. Baseline data and risk factors were collected. Hepatitis A-E serology was measured, including hepatitis B e antigen, antibodies to hepatitis B e antigen, antibodies to hepatitis D, hepatitis B virus (HBV) DNA for hepatitis B surface antigen (HBsAg)-positive participants, and antibodies to hepatitis B surface antigen and antibodies to hepatitis B core antigen (anti-HBc) in HBsAg-negative participants. Hepatitis C virus (HCV) RNA and genotypes were determined in anti-HCV-positive participants. RESULTS A total of 10 256 participants were recruited from February 2015 to July 2016. Overall HBsAg seroprevalence was 7.8% (95% confidence interval [CI], 7.3%-8.3%), which was reduced significantly with HBV vaccination (odds ratio, 0.15 [95% CI, .11-.21]). Among HBsAg-negative participants, anti-HBc seroprevalence increased from 5.4% (<26 years) to 60.1% (>65 years). No hepatitis D virus (HDV) cases were detected. Anti-HCV positivity was 0.5% (95% CI, .3%-.6%). Prevalence of antibodies to hepatitis A virus (anti-HAV) and hepatitis E virus (anti-HEV) was 65.2% (95% CI, 64.2%-66.1%) and 33.3% (95% CI, 32.4%-34.2%), respectively, and were influenced by age, family income, and being born in mainland China. CONCLUSIONS HBV seroprevalence remained high despite universal vaccination. High anti-HBc seroprevalence underlines the potential issue of HBV reactivation during profound immunosuppression. HCV and HDV remained uncommon. Anti-HAV seroprevalence had decreased whereas anti-HEV seroprevalence had risen.

Abstract
The Asia-Pacific region is home to more than half of the global population and accounted for 62·6% of global deaths due to liver diseases in 2015. 54·3% of global deaths due to cirrhosis, 72·7% of global deaths due to hepatocellular carcinoma, and more than two-thirds of the global burden of acute viral hepatitis occurred in this region in 2015. Chronic hepatitis B virus (HBV) infection caused more than half of the deaths due to cirrhosis in the region, followed by alcohol consumption (20·8%), non-alcoholic fatty liver disease (NAFLD; 12·1%), and chronic infection with hepatitis C virus (HCV; 15·7%). In 2015, HBV accounted for about half the cases of hepatocellular carcinoma in the region. Preventive strategies for viral hepatitis-related liver disease include increasing access to clean drinking water and sanitation. HBV vaccination programmes for neonates have been implemented by all countries, although birth-dose coverage is extremely suboptimal in some. Availability of screening tests for blood and tissue, donor recall policies, and harm reduction strategies are in their initial stages in most countries. Many governments have put HBV and HCV drugs on their essential medicines lists and the availability of generic versions of these drugs has reduced costs. Efforts to eliminate viral hepatitis as a public health threat, together with the rapid increase in per-capita alcohol consumption in countries and the epidemic of obesity, are expected to change the spectrum of liver diseases in the Asia-Pacific region in the near future. The increasing burden of alcohol-related liver diseases can be contained through government policies to limit consumption and promote less harmful patterns of alcohol use, which are in place in some countries but need to be enforced more strictly. Steps are needed to control obesity and NAFLD, including policies to promote healthy lifestyles and regulate the food industry. Inadequate infrastructure and insufficient health-care personnel trained in liver diseases are issues that also need to be addressed in the Asia-Pacific region. The policy response of most governments to liver diseases has thus far been inadequate and poorly funded. There must be a renewed focus on prevention, early detection, timely referral, and research into the best means to introduce and improve health interventions to reduce the burden of liver diseases in the Asia-Pacific region.

Abstract
Background Aspartate transaminase-platelet ratio index (APRI) and fibrosis 4 (FIB-4) are two non-invasive indexes to predict liver fibrosis in liver disease. This study was to use APRI and FIB-4 to detect chronic virus hepatitis in community screenings. Methods From 2004 to 2013, a series of community-based health screenings for residents aged 40 and older were held in Tainan city. APRI and FIB-4 of each participant were calculated and their association further analyzed with hepatitis status. Results We enrolled 180359 participants including 18726 (10.4%) hepatitis B virus (HBV), 13428 (7.4%) hepatitis C virus (HCV), 1337 (0.7%) HBV plus HCV and 146868 (81.5%) Non-HBV Non-HCV. The prevalence of chronic HCV increased with the elevation of APRI cut-offs or FIB-4 cut-offs (13.9%, 28.1%, 38.8%, 45.2%, to 49.9% in APRI≥0.3, 0.5, 0.7, 0.9,1.1, p<0.001 for the linear trend; or 15.8%, 26.4%, 34.4% to 39.7% in FIB-4≥1.75, 2.75, 3.5, 4.25, p<0.001). At the township level, APRI≥ 0.7 and FIB-4≥ 3.5 were highly correlated with HCV infection (r = 0.95, p<0.001 in APRI and r = 0.809, p<0.001 in FIB-4) and hepatocellular carcinoma (HCC) development (r = 0.894, p<0.001 in APRI and r = 0.804, p<0.001 in FIB-4), but not correlated with HBV infection. Conclusions Community screenings derived APRI or FIB-4 can identify patient subsets with increased of underlying HCV infection and risk of incident HCC.

A novel one-step quantitative reverse transcription PCR assay for selective amplification of hepatitis B virus pregenomic RNA from a mixture of HBV DNA and RNA in serum. Arch Virol 2019; 164:2683-2690.

Abstract
Current antiviral therapies against hepatitis B virus (HBV) infections, such as treatment with nucleos(t)ide analogs (NAs) and interferon alpha, can significantly lower HBV DNA titers, eventually to undetectable levels. However, it is still difficult to completely eliminate the stable template of HBV, the covalently closed circular DNA (cccDNA), and this contributes to viral rebound when treatment is discontinued. HBV pregenomic RNA (pgRNA), which was recently found to be present in the enveloped mature HBV viral particle in blood, is tentatively regarded, with still accumulating clinical evidence, as a novel bona fide virological marker reflecting the amount and status of cccDNA when serum HBV DNA becomes undetectable. HBV pgRNA and DNA share almost identical sequences, and it is therefore difficult to differentiate pgRNA from viral DNA using normal PCR methods. To exclude interference from viral DNA, methods for measuring pgRNA usually require a selective DNA degradation step, which is complicated and time-consuming and also compromises the accuracy of detection. In this study, we developed a simplified quantitative reverse transcription polymerase chain reaction (qRT-PCR) assay with improved accuracy achieved by probing the polyA tail of pgRNA. Using clinical serum samples, we observed that not all patients share the same 3' sequence, suggesting slight differences between HBV strains in the way they end transcription. We then designed and evaluated a universal primer and probe set for distinguishing HBV pgRNA from HBV DNA. Our results demonstrated that a one-step qRT-PCR assay could selectively amplify HBV pgRNA from a mixture of HBV RNA and DNA, which is valuable for clinical applications.

Abstract
The incidence and prevalence of inflammatory bowel disease (IBD) are low but increasing in Taiwan. We aimed to investigate the epidemiology and clinical outcomes of IBD in central Taiwan. We retrospectively analyzed patients with IBD diagnosed at our hospital between January 2000 and September 2018. The diagnostic criteria were based on endoscopic and pathologic findings. Clinical characteristics, treatment regimens, and treatment outcomes were analyzed. A total of 190 patients with IBD were enrolled (80 with Crohn's disease (CD) and 110 with ulcerative colitis (UC)). The mean age at diagnosis was 38.4 years (CD: 36 years, UC: 40 years). Male patients accounted for the majority of patients (71.1%). The male-to-female ratio was 3 : 1 for CD and 2.1 : 1 for UC. Current and ever smokers accounted for 30.5% of all patients. Only 4.2% of patients had a family history of IBD. Extraintestinal manifestations (EIMs) were reported in 7.9%, and colorectal cancers (CRCs) were reported in 2.1% of all patients. In patients with CD, the ileal type was the most common disease phenotype (57.5%), and the stricturing type was the most common disease behavior (60.0%). In patients with UC, left-sided colitis was the predominant disease extent (42.7%). The seroprevalence of hepatitis B virus (HBV) was 13.3%. The incidence of perinuclear anti-neutrophil cytoplasmic antibody (p-ANCA) in patients with UC was 22%. 5-Aminosalicylic acids were the preferred treatment for UC, whereas corticosteroids, immunomodulators, and biologic agents were preferred for CD. In patients with CD, the bowel resection rate was 38.8%, and the incidence of hip avascular necrosis was 3.8%. In Taiwan, patients with IBD showed a male predominance, lack of familial clustering, a higher prevalence of HBV infection, and a lower prevalence of p-ANCA, EIMs, and CRC. Moreover, a higher incidence of the ileal type with poor outcomes of CD and left-sided predominance in UC were found.

Abstract
AIM Longitudinal data of the reactivation of hepatitis B virus (rHBV) and serial serological markers or HBV-DNA has been limited. This study aimed to investigate the temporal course of rHBV development in rheumatoid arthritis (RA) patients undergoing long-term rituximab therapy. METHODS The occurrence of rHBV was examined in 157 RA patients during rituximab therapy. Serum levels of HBV surface antigen (HBsAg), HBV core antibody (HBcAb), and HBsAb were determined by electrochemiluminescence immunoassays, and viral loads by real-time polymerase chain reaction assay. RESULTS Among 157 patients undergoing rituximab therapy, 103 (65.6%) were HBsAg-negative and HBcAb-positive. Before rituximab therapy, 20 (19.4%) of these 103 patients were HBsAb-negative, while 83 (80.1%) were HBsAb-positive. Five (20%) HBsAb-negative patients developed rHBV after rituximab therapy. Among 83 HBsAb-positive patients, 4 (4.8%) developed rHBV. Among 9 patients with rHBV, 7 (77.7%) exhibited HBsAg seroreversion. Significant decline of HBsAb titers (mean ± SD, 296.0 ± 417.3 mIU/mL at baseline vs 187.0 ± 332.5 mIU/mL after rituximab therapy, P < 0.001) was observed in HBsAg-/HBsAb + patients. All HBsAg-negative patients who developed rHBV during rituximab therapy were characterized by baseline HBsAb titers < 100 mIU/mL and negative HBsAb at the time of rHBV. HBsAb positivity was an independent protective factor for rHBV (hazards ratio: 0.14, 95% CI: 0.03-0.62, P = 0.009). CONCLUSION Baseline HBsAb positivity was a significant protective factor for rHBV in HBsAg-negative, HBcAb-positive RA patients receiving rituximab therapy.

Abstract
BACKGROUND Most of the previous reports regarding the clinical features of Kaposi's sarcoma (KS) have been performed in Western and African countries. The clinical characteristics of KS have not been well defined in Han Chinese or Taiwanese patients. In this study, we analyzed the clinical features of KS patients in a Taiwanese medical center. METHODS Medical records from Kaohsiung Medical University Hospital over the past 20 years (1996-2016) were comprehensively reviewed. RESULTS There were 55 patients with KS (50 males and 5 females), including 37 patients (67%) with classic disease, 17 patients (31%) with AIDS-associated disease, and one patient (2%) with immunosuppressive medication-related disease. The average age was 58.7 years (range 20-87 years), and the average age was younger for AIDS patients (33.8 years) compared with non-AIDS patients (69.8 years). Among patients with classic KS, lesions were mostly localized to the lower extremities, whereas AIDS-associated KS patients were more likely to develop disseminated skin lesions, skin lesions on atypical sites (head and neck, trunk), and extracutaneous involvement (particularly oral cavity). The most common underlying diseases were diabetes mellitus (20% of patients) and hepatitis B (15% patients), and 38% of KS patients were smokers. Patients with AIDS-associated KS usually responded well to chemotherapy, whereas only 32% of patients with non-AIDS-associated KS showed complete response to radiotherapy. CONCLUSIONS The findings of the current study will serve as important references for clinicians in the diagnosis of KS and may form the basis for the implementation of KS clinical practice guidelines in Taiwan.

Abstract
Hepatitis B and C are common viral infections that affect more than 430 million population worldwide. In patients with rheumatic diseases, the prevalence of inactive/chronic hepatitis B infection ranges from 0.4% to 38% and that of past/resolved infection is much higher (7.3%-69%). The prevalence of hepatitis C infection in rheumatic disorders is less clear but probably lower than that of hepatitis B (1.7%-4%). With the increasing use of biologic and targeted disease-modifying antirheumatic drug therapies, reactivation of past and chronic hepatitis B and C infection is increasingly recognized, with presentation ranging from asymptomatic viremia to serious clinical hepatitis with liver failure. The concomitant use of effective antiviral therapies helps reduce the risk of hepatitis B reactivation and control of active hepatitis C infection. This article summarizes the prevalence and risk factors of hepatitis B and C reactivation in patients with rheumatic diseases undergoing biologic and targeted therapies, as well as the recommendations for screening, monitoring, and treatment of these infections.

Abstract
BACKGROUND Spontaneous loss of HBsAg (known as functional cure) in patients with chronic hepatitis B virus (HBV) infection significantly reduces liver-related complications. HBsAg loss has been suggested to be higher in non-endemic regions than in endemic regions in individual studies. We systematically determined a pooled annual rate of HBsAg loss in adults with untreated chronic HBV infection and examined the effect of regional endemicity. METHODS In this systematic review and meta-analysis, we searched PubMed and Embase for observational cohort studies and non-treatment arms of randomised controlled trials reporting proportions of patients with chronic HBV infection that achieved spontaneous HBsAg loss, published up to Oct 1, 2018. We excluded randomised controlled trials from meta-analyses because of substantial cohort differences. Two reviewers (KZ and CC) independently extracted data from accepted full-text studies, with discrepancies discussed with a third reviewer (NT). We assessed rate of HBsAg loss, and stratified results by whether the underlying cohort arose primarily from an endemic region (defined as having prevalence of chronic HBV greater than 2%) or non-endemic region. This study is registered with PROSPERO, number CRD42018074086. FINDINGS Of 5186 studies screened, 67 (11 randomised controlled trials, 39 prospective and 17 retrospective cohort studies) met the inclusion criteria and 56 were included in meta-analyses after exclusion of randomised controlled trials. Spontaneous HBsAg loss occurred in 3837 (7·8%) of 48 972 patients, with cumulative 352 381 person-years of follow-up. The pooled annual incidence of HBsAg loss was 1·17% (95% CI 0·94-1·41, I2=97%). Rates did not differ by endemicity: 1·19% (0·88-1·54) in endemic versus 1·29% (0·99-1·62) in non-endemic cohorts. INTERPRETATION Globally, spontaneous HBsAg loss occurs infrequently (about 1% per year) in treatment-naive adults with chronic HBV infection. The low and homogeneous rate of HBsAg loss highlights the need for new therapeutics aimed at achieving functional cure across different patient groups and geographical regions.

This study aimed to assess the risk of acute exacerbation of hepatitis and subsequent cirrhosis and hepatoma in HBV patients with and without CHM use. DESIGN AND SETTING This population-based case-control study used data from the Taiwan Longitudinal Health Insurance Database from 2000 to 2013. Newly diagnosed HBV patients had acute exacerbation of hepatitis and subsequent cirrhosis and hepatoma as the case group, while another patients had no acute exacerbation of hepatitis and cirrhosis and hepatoma as the control group. To correct the differences in sociodemographic factors and Western medication use between the two groups, propensity score matching was used at a 1:1 ratio, and resulted in a comparison of 1306 and 805 patients per group, respectively. MAIN OUTCOME MEASURES Occurrence of acute exacerbation of hepatitis and subsequent cirrhosis and hepatoma. RESULTS Overall rate of acute exacerbation of hepatitis and subsequent cirrhosis and hepatoma was 7.9% and 4.8%, respectively. Patients receiving CHM had a significantly lower risk of acute exacerbation of hepatitis (adjusted odds ratio [aOR] =0.20, 95% confidence interval [95%CI]: 0.13-0.31) and subsequent cirrhosis and hepatoma (aOR = 0.29, 95%CI: 0.18-0.49) than those not receiving CHM after adjusting for relevant covariates. However, no dose-dependent relationship was exhibited for either incidence of acute exacerbation of hepatitis and cirrhosis and hepatoma. CONCLUSION These findings highlight that the use of CHM was associated with a significantly reduced risk of acute exacerbation of hepatitis and subsequent cirrhosis and hepatoma in patients with HBV. Future research could further explore the benefit of CHM therapies for treatment of acute hepatitis exacerbation.

Abstract
BACKGROUND & AIMS Non-invasive assessment methods for liver fibrosis are urgently needed. The present study aimed to develop a novel diagnostic model for fibrosis staging in patients with chronic hepatitis B. METHODS A cross-sectional set of 417 chronic hepatitis B patients who underwent liver biopsy was enrolled and the METAVIR score was adopted as the reference of fibrosis staging. RESULTS Among thyroid hormones, only the level of free tetraiodothyronine (FT4) decreased gradually with the METAVIR fibrosis score (P < .001). FibroStage, a novel diagnosis model that incorporates data on FT4, platelets, cholinesterase, gamma-glutamyl transpeptidase, and age, was developed using the deriving set (n = 219). For the diagnosis of significant fibrosis, the FibroStage model had a significantly higher area under the receiver operating curve than did the FibroIndex, Forn, and Lok models (all of P < .01) and tended to better than the fibrosis-4 (P = .0791) but comparable with the aspartate transaminase-to-platelet ratio index model (P = .1694). For the diagnosis of advanced fibrosis, FibroStage had a higher area under the receiver operating curve than did the aspartate transaminase-to-platelet ratio index, FibroIndex, Forn, and Lok models (all of P < .05) and had a comparable area under the receiver operating curve with the fibrosis-4 model (P = .2109). For the diagnosis of cirrhosis, the area under the receiver operating curve of FibroStage was higher than those of the aspartate transaminase-to-platelet ratio index, fibrosis-4, FibroIndex, and Lok (all of P < .05) models and was comparable with Forn (P = .1649). These results was validated by a validation set (n = 198). CONCLUSION FT4 may be an indicator for fibrosis staging in chronic hepatitis B patients. FibroStage is a better model than aspartate transaminase-to-platelet ratio index, fibrosis-4, FibroIndex, Forn, and Lok for the comprehensively diagnosis of significant and advanced fibrosis and cirrhosis.

Abstract
The primary goals of managing chronic hepatitis B (CHB) are prevention of liver-related complications and reduction of mortality. Universal vaccination has dramatically reduced the incidence of new infection, but the management of existing CHB patients are still challenging. Areas covered: This review compares the similarities and differences among the latest published regional guidelines on the indications and choices of antiviral therapy. We have summarized advances in virological biomarkers and non-invasive tests for liver fibrosis in disease assessment. Benefits and remaining challenges of current standard of care by peginterferon and nucleos(t)ide analogs (NA) have been presented. Data on combination therapy of peginterferon and NA in seeking functional cure of the disease is also critically discussed. We have also described the improvement in the management of CHB at pregnancy and prophylaxis in patients on chemotherapy and immunosuppressants. Expert commentary: Controversies exist in the assessment of disease activity for selection patients for treatment as well as on the use of tenofovir alafenamide as a safe and cost-effective alternative to tenofovir disoproxil fumarate. Though combination therapy of peginterferon and NA has induced HBsAg seroclearance in a small proportion of patients, peginterferon is not preferred in the future trend of drug development.

Abstract
Background In this study, the long-term efficacy of hepatitis B virus (HBV) vaccination was assessed using seroprevalence and an age–period–cohort (APC) model of HBV seromarkers among university entrants 30 years after the introduction of the national neonatal HBV vaccination program in Taiwan. Methods In total, data of 17,611 university entrants who underwent university entrance health examinations between 2005 and 2016 were included. The seroprevalence of the HBV surface antigen (HBsAg) and the levels of the antibody against the HBV surface antigen (anti-HBs) in each year group and sex were calculated. The levels of the antibody against the HBV core antigen were examined only for 2012 and 2016. The APC model was used to analyze the HBV carrier rates. Results The chronic HBV infection (HBsAg positivity) rate decreased from 9.7% in university students born before June 1974 to <1.0% in students born after 1992. The prevalence of anti-HBs positivity declined, particularly between the 1984–1988 cohort (78.2%–53.2%) and the 1990–1994 cohort (60.6%–44.4%). Our APC model revealed that the chronic HBV carrier rate among the student population was affected significantly by age, period, and cohort (P < 0.001). Conclusions HBV vaccination is one of the most effective strategies for preventing HBV infection. However, for complete eradication of HBV infection, the development of strategies that detect vaccination failure more effectively than current strategies do and early implementation of appropriate treatments are both necessary.

Abstract
Spontaneous subarachnoid hemorrhage (SAH) is a devastating disease, and gastrointestinal hemorrhage is one of several potential complications of acute strokes. We aim to analyze its prevalence, risk factors, and association with in-hospital prognosis following SAH. A total of 1047 adult patients with a primary diagnosis of spontaneous SAH were retrospectively enrolled. We retrieved medical information from the administrative database utilizing diagnostic and procedure codes of the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM). Patients with SAH included 418 men and 629 women, and their mean age was 57.2 (standard deviation 14.6) years (range, 18–93 years). Gastrointestinal hemorrhage occurred in 30 of the 1047 patients, accounting for 2.9%. In a multivariate logistic regression model, the independent risk factors for gastrointestinal hemorrhage were liver disease and hydrocephalus. The in-hospital mortality rates were 43.3% and 29.3% in patients with and without gastrointestinal hemorrhage, respectively, but the difference was not statistically significant. In conclusion, the prevalence of gastrointestinal hemorrhage was 2.9% in patients hospitalized for spontaneous SAH. Underlying liver disease and the presence of hydrocephalus were both independent risk factors for this complication, which is a reminder to clinicians to pay increased attention in such cases.

Abstract
Hepatitis B virus (HBV) infection has been documented as a risk factor for non-Hodgkin lymphoma (NHL). However, there are few large cohort studies, and there is no report about the impact of HBV vaccination. We conducted this study to evaluate these issues. We used the nationwide cohort of the Taiwan National Health Insurance Research Database for 1997-2013. We compared the incidence and the risk of developing NHL and CD20+ aggressive lymphoma between HBV and non-HBV cohorts. The hazard ratios (HRs) were computed using Cox proportional hazards models. We matched these two large cohorts to reconfirm the data. We also compared the incidence of NHL between cohorts born before and after the inception of universal HBV vaccination. We found that HBV infection increased the risk for developing NHL and CD20+ aggressive lymphoma, with HRs of 4.14 and 5.52, with a higher incidence of 17.07 and 13.9 per 100 000 person-years, respectively, compared to the non-HBV cohort. The incidence of NHL in the cohort born in the era before universal HBV vaccination was higher with 1.85 per 100 000 person-years compared to 0.74 in the cohort born later aged younger than 20. Our study confirms that HBV confers a greater risk for developing NHL, especially CD20+ aggressive lymphoma. The impact of HBV vaccination is protective against lymphoma development in the teenagers in an endemic area, but longer follow-up is needed for older age.

Abstract
OBJECTIVES The association between hepatitis B virus (HBV) infection and cardiovascular disease remains uncertain. This study explored long-term hard endpoints (ie, myocardial infarction and ischaemic stroke) and all-cause mortality in diabetic patients with chronic HBV infection in Taiwan from 2000 to 2013. DESIGN This study was retrospective, longitudinal and propensity score-matched.Setting Nationwide claims data for the period 2000-2013 were retrieved from Taiwan's National Health Insurance Research Database. PARTICIPANTS The study included 40 162 diabetic patients with chronic HBV infection (HBV cohort) and 40 162 propensity score-matched diabetic patients without HBV infection (control cohort). Chronic HBV infection was identified based on three or more outpatient clinic visits or one hospital admission with a diagnosis of HBV infection. MAIN OUTCOME MEASURES Primary outcomes were major adverse cardiovascular events (MACE, including myocardial infarction and ischaemic stroke), heart failure and all-cause mortality. RESULTS During the median follow-up period of 5.3±3.4 years, the HBV cohort had significantly lower risks of myocardial infarction (adjusted HR (aHR)=0.49; 95% CI 0.42 to 0.56), ischaemic stroke (aHR=0.61; 95% CI 0.56 to 0.67), heart failure (aHR=0.50; 95% CI 0.43 to 0.59) and all-cause mortality (aHR=0.72; 95% CI 0.70 to 0.75) compared with the control cohort. The impact of HBV infection on the sequential risk of MACE was greater in patients with fewer diabetic complications. CONCLUSIONS Chronic HBV infection was associated with decreased risk of MACE, heart failure and all-cause mortality in patients with diabetes. Further research is needed to investigate the mechanism underlying these findings.

Abstract
Hepatitis B virus (HBV) infection remains a global public health problem with changing epidemiology due to several factors including vaccination policies and migration. This Clinical Practice Guideline presents updated recommendations for the optimal management of HBV infection. Chronic HBV infection can be classified into five phases: (I) HBeAg-positive chronic infection, (II) HBeAg-positive chronic hepatitis, (III) HBeAg-negative chronic infection, (IV) HBeAg-negative chronic hepatitis and (V) HBsAg-negative phase. All patients with chronic HBV infection are at increased risk of progression to cirrhosis and hepatocellular carcinoma (HCC), depending on host and viral factors. The main goal of therapy is to improve survival and quality of life by preventing disease progression, and consequently HCC development. The induction of long-term suppression of HBV replication represents the main endpoint of current treatment strategies, while HBsAg loss is an optimal endpoint. The typical indication for treatment requires HBV DNA >2,000IU/ml, elevated ALT and/or at least moderate histological lesions, while all cirrhotic patients with detectable HBV DNA should be treated. Additional indications include the prevention of mother to child transmission in pregnant women with high viremia and prevention of HBV reactivation in patients requiring immunosuppression or chemotherapy. The long-term administration of a potent nucleos(t)ide analogue with high barrier to resistance, i.e., entecavir, tenofovir disoproxil or tenofovir alafenamide, represents the treatment of choice. Pegylated interferon-alfa treatment can also be considered in mild to moderate chronic hepatitis B patients. Combination therapies are not generally recommended. All patients should be monitored for risk of disease progression and HCC. Treated patients should be monitored for therapy response and adherence. HCC remains the major concern for treated chronic hepatitis B patients. Several subgroups of patients with HBV infection require specific focus. Future treatment strategies to achieve 'cure' of disease and new biomarkers are discussed.

Interval to vascularization development in cirrhotic precursor nodules in patients with hepatitis B and C virus co-infections. PLoS One 2017; 12:e0178841. [PMID: 28591226 PMCID: PMC5462400 DOI: 10.1371/journal.pone.0178841] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2017] [Accepted: 05/19/2017] [Indexed: 12/15/2022] Open
Abstract
With the widespread use of gadoxetic acid-enhanced magnetic resonance imaging, liver nodules appearing as hypovascular in the arterial phase and hypointense in the hepatobiliary phase, defined as hypovascular hypointense nodules, are increasingly detected in patients with cirrhosis and are considered precursor nodules. We sought to evaluate the interval to vascularization development in hepatitis C virus/hepatitis B virus co-infected-associated precursor nodules (BC-HHN group) compared with that in hepatitis C virus mono-infected-associated precursor nodules (C-HHN group) in the hepatobiliary phase of gadoxetic acid-enhanced magnetic resonance imaging. The interval to vascularization development was estimated by the Kaplan-Meier method and compared using the Cox proportional hazards model. The mean intervals to vascularization development in the BC-HHN and C-HHN groups were 272.9±31.1 and 603.8±47.6 days, respectively (p<0.001). The cumulative vascularization development incidence at 6, 12, and 18 months was 44.9%, 73.5%, and 91.8%, respectively, in the BC-HHN group and 16.9%, 39.0%, and 55.8%, respectively, in the C-HHN group (p<0.001). The multivariate analysis showed that the presence of hepatitis B virus co-infection (hazard ratio: 1.819; 95% confidence interval: 1.222–2.707; p = 0.003) and male sex (hazard ratio: 1.753; 95% confidence interval: 1.029–2.985; p = 0.039) were predictors of vascularization development. More than half of the hypovascular hypointense nodules showed high-signal changes on T2-weighted imaging, and almost half of them showed restricted diffusion on diffusion-weighted images, but these did not predict vascularization development. In a hepatitis C virus- and hepatitis B virus-endemic area, such as Taiwan, precursor nodules in the BC-HHN group tended to have shorter intervals to vascularization development, especially in male patients.

Virus-induced hepatocellular carcinoma with special emphasis on HBV. Hepatol Int 2017; 11:171-180. [PMID: 28097530 DOI: 10.1007/s12072-016-9779-5] [Citation(s) in RCA: 38] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/02/2016] [Accepted: 12/22/2016] [Indexed: 12/12/2022]
Abstract
Hepatocellular carcinoma (HCC) is a common malignant tumor with high lethality, and the hepatitis B virus (HBV) is a chief cause. HBV can accelerate HCC via multiple mechanisms. First, HBV induces immune reactions that lead to repeated hepatic inflammation, fibrosis and a deficient immune microenvironment. Subsequently, HBV can modify host genes near the insertion point through DNA integration to cause host cell genome instability and to generate carcinogenic fusion proteins. Additionally, HBV expresses diverse active proteins, especially HBx and HBs, which have a range of transactivation functions such as regulation of apoptosis, interference with intracellular signaling pathways, and alteration of epigenetics. Currently, primary prevention measures for HBV-induced HCC focus on vaccination and antiviral treatment. Here, we report the epidemiology, the molecular mechanism and the progress in therapeutic strategies for controlling HBV-induced HCC.
