Abstract
Despite the availability of an effective vaccination, chronic hepatitis B virus (HBV) infection is still a major health concern worldwide. Chronic HBV infection can lead to fibrosis accumulation and overtime to cirrhosis, the principal risk factor for liver failure and hepatocellular carcinoma development. Liver biopsy is still considered the gold standard for fibrosis assessment, even though it is invasive and not exempt of complications. Overtime, several non-invasive methods for the detection of liver fibrosis have been developed and gradually introduced into clinical practice. However, their main limitation is the poor performance for the detection of intermediate stages of fibrosis. Finally, novel serological biomarkers, polygenic risk scores and imaging methods have been proposed in last years as novel promising tools to correctly identify the degree of liver fibrosis and to monitor liver disease progression. In this narrative review, we provide an overview on the novel non-invasive approaches for the evaluation of liver fibrosis and risk stratification of patients with chronic hepatitis B.

Development of a cellular high-content, immunofluorescent HBV core assay to identify novel capsid assembly modulators that induce the formation of aberrant HBV core structures. J Virol Methods 2021; 293:114150. [PMID: 33839187 DOI: 10.1016/j.jviromet.2021.114150] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2020] [Revised: 03/19/2021] [Accepted: 04/06/2021] [Indexed: 01/05/2023]
Abstract
Hepatitis B Virus (HBV) core protein has multiple functions in the viral life cycle and is an attractive target for new anti-viral therapies. Capsid assembly modulators (CAMs) target the core protein and induce the formation of either morphologically normal (CAM-N) or aberrant structures (CAM-A), both devoid of genomic material. To date a diverse family of CAM-N chemotypes has been identified, but in contrast, described CAM-As are based on the heteroaryldihydropyrimidine (HAP) scaffold. We used the HBV-inducible HepG2.117 cell line with immunofluorescent labeling of HBV core to develop and validate a cellular high-content image-based assay where aggregated core structures are identified using image analysis spot texture features. Treatment with HAPs led to a dose- and time-dependent formation of aggregated core appearing as dot-like structures in the cytoplasm and nucleus. By combining a biochemical and cellular screening approach, a compound was identified as a novel non-HAP scaffold able to induce dose-dependent formation of aberrant core structures, which was confirmed by electron microscopy and native gel electrophoresis. This compound displayed anti-HBV activity in HepG2.117 cells, providing proof-of-concept for our screening approach. We believe our combined biochemical and cellular high-content screening method will aid in expanding the range of CAM-A chemotypes.

Abstract
Certain infectious diseases are common in infants than any other age groups and are associated with morbidities in childhood and adulthood, and even mortality in severe cases. Environment, epidemic and maternal immunity are the main causes of these infections. Early diagnosis using molecular methods and treatment is therefore important to prevent future complications. Vaccines are recommended during infancy and childhood to prevent these infections. This review highlights some of the most commonly reported viral infections in children, their clinical signs, prevention and treatment.

Abstract
Background To explore the role of natural killer (NK) cells in the process of hepatitis B virus (HBV) clearance and whether their phenotype is related to antiviral treatment outcome in chronic hepatitis B (CHB) patients. Method We performed a single-center prospective cohort study to analyze changes of NK cells at weeks 12 and 24 from baseline in CHB patients who received PEGylated-interferon- (PEG-IFN-) α-2a versus entecavir. The frequencies of NK, CD56bright, CD56dim, IFNAR2+, NKp46+, NKp46bright, and NKp46dim NK cells and mean fluorescence intensity (MFI) of receptors NKp46 and IFNAR2 on the surface of NK cells were measured. Subgroup analyses were performed by comparing treatment responders versus nonresponders with aforementioned parameters in each group. Results In PEG-IFN-α-treated patients, posttreatment CD56bright NK cell frequency increased, but CD56dim NK cell frequency decreased. Additionally, receptor NKp46 and IFNAR2 expression enhanced. In entecavir-treated patients, although NK cell frequency increased, CD56bright and CD56dim NK cell frequencies and IFNAR2 expression did not differ between baseline and posttreatment. In subgroup analyses, posttreatment CD56bright NK cell frequency and IFNAR2 expression significantly increased in PEG-IFN-α responders from baseline, while changes were absent in PEG-IFN-α nonresponders and entecavir treatment responders. Among patients with HBV viremia after entecavir therapy, NK cell frequency significantly increased, whereas NKp46bright and IFNAR2+ NK frequency and IFNAR2 MFI significantly decreased at 12 and 24 weeks from baseline. Conclusions In CHB patients, PEG-IFN-α treatment significantly enhanced NK cell frequency and function when compared to entacavir. Positive treatment responses to either interferon or entecavir were associated with NK cell function improvement. This trial is registered with clinical trial registration no. NCT03208998.

Abstract
Hepatitis B virus (HBV) mediates persistent infection, chronic hepatitis, and liver disease. HBV covalently closed circular (ccc)DNA is central to viral persistence such that its elimination is considered the cornerstone for HBV cure. Inefficient detection by pathogen recognition receptors (PRRs) in the infected hepatocyte facilitates HBV persistence via avoidance of innate immune activation and interferon regulatory factor (IRF)3 induction of antiviral gene expression. We evaluated a small molecule compound, F7, and 5'-triphosphate-poly-U/UC pathogen-associated-molecular-pattern (PAMP) RNA agonists of RIG-I, a PRR that signals innate immunity, for ability to suppress cccDNA. F7 and poly-U/UC PAMP treatment of HBV-infected cells induced RIG-I signaling of IRF3 activation to induce antiviral genes for suppression of cccDNA formation and accelerated decay of established cccDNA, and were additive to the actions of entecavir. Our study shows that activation of the RIG-I pathway and IRF3 to induce innate immune actions offers therapeutic benefit toward elimination of cccDNA.

Abstract
Hepatitis B virus (HBV) is a major focus of antiviral research worldwide. The International Coalition to Eliminate HBV, together with the World Health Organisation (WHO), have prioritised the search for a cure, with the goal of eliminating deaths from viral hepatitis by 2030. We present here a comprehensive model of intracellular HBV infection dynamics that includes all molecular processes currently targeted by drugs and agrees well with the observed outcomes of several clinical studies. The model reveals previously unsuspected kinetic behaviour in the formation of sub-viral particles, which could lead to a better understanding of the immune responses to infection. It also enables rapid comparative assessment of the impact of different treatment options and their potential synergies as combination therapies. A comparison of available and currently developed treatment options reveals that combinations of multiple capsid assembly inhibitors perform best.

Abstract
The chronic factor of the Hepatitis B Virus (HBV), specifically the covalently closed circular DNA (cccDNA), is a highly stable and active viral episomal genome established in the livers of chronic hepatitis B patients as a constant source of disease. Being able to target and eliminate cccDNA is the end goal for a genuine cure for HBV. Yet how HBV cccDNA is formed from the viral genomic relaxed circular DNA (rcDNA) and by what host factors had been long-standing research questions. It is generally acknowledged that HBV hijacks cellular functions to turn the open circular DNA conformation of rcDNA into cccDNA through DNA repair mechanisms. With great efforts from the HBV research community, there have been several recent leaps in our understanding of cccDNA formation. It is our goal in this review to analyze the recent reports showing evidence of cellular factor's involvement in the molecular pathway of cccDNA biosynthesis.

Preclinical Profile and Characterization of the Hepatitis B Virus Core Protein Inhibitor ABI-H0731. Antimicrob Agents Chemother 2020; 64:AAC.01463-20.

Abstract
ABI-H0731, a first-generation hepatitis B virus (HBV) core protein inhibitor, has demonstrated effective antiviral activity in chronic hepatitis B (CHB) patients in a phase 1b clinical trial and is currently being further evaluated in phase 2 clinical trials. Here, we report the preclinical profile of ABI-H0731. In in vitro cell culture systems (HepG2-derived cell lines HepAD38 and HepG2-NTCP and primary human hepatocytes [PHHs]), ABI-H0731 exhibited selective inhibition of HBV DNA replication (50% effective concentration [EC50] from 173 nM to 307 nM). ABI-H0731, a first-generation hepatitis B virus (HBV) core protein inhibitor, has demonstrated effective antiviral activity in chronic hepatitis B (CHB) patients in a phase 1b clinical trial and is currently being further evaluated in phase 2 clinical trials. Here, we report the preclinical profile of ABI-H0731. In in vitro cell culture systems (HepG2-derived cell lines HepAD38 and HepG2-NTCP and primary human hepatocytes [PHHs]), ABI-H0731 exhibited selective inhibition of HBV DNA replication (50% effective concentration [EC50] from 173 nM to 307 nM). Most importantly, ABI-H0731 suppressed covalently closed circular DNA (cccDNA) formation in two de novo infection models with EC50s from 1.84 μM to 7.3 μM. Mechanism-of-action studies indicated that ABI-H0731 is a direct-acting antiviral that targets HBV core protein, preventing HBV pregenomic RNA (pgRNA) encapsidation and subsequent DNA replication. The combination of ABI-H0731 with entecavir appears to decrease viral DNA faster and deeper than nucleoside/nucleotide analogue (NrtI) therapy alone. In addition, ABI-H0731 disrupts incoming nucleocapsids, causing the premature release of relaxed circular DNA (rcDNA) before delivery to the nucleus, and thus prevents new cccDNA formation. ABI-H0731 exhibits pangenotypic activity and is additive to moderately synergistic when combined with an NrtI. In addition to its potency and novel mechanism of action, ABI-H0731 possesses drug-like properties and a preclinical pharmacokinetic profile supportive of once-daily dosing in patients with CHB. Taken together, these data support the ongoing clinical development of ABI-H0731 as a treatment for HBV.

Abstract
Infection caused by hepatitis B virus (HBV) can be prevented through a safe and effective vaccine. This study analysed the kinetics of serum antibodies against hepatitis B surface antigen (HBsAg) (anti-HBs) titers in relation to previous vaccine boosters in Italian nursing students who were followed up for two years. Serum anti-HBs titers were evaluated at the first visit, after vaccine booster (if required) and at visit after two years. Overall, 483 students (mean age = 21.7 years; SD = 3.7) with median anti-HBs IgG titer of 6 mUI/mL (interquartile range (IQR) = 0–34) were enrolled. A total of 254 (52.5%) students with a titer lower than 10 mIU/mL were offered an anti-HBV booster at the first visit. Among these students, an exponential relation between anti-HBs IgG titer, one month after HBV booster and anti-HBs IgG titer two years later was found (y = 3.32 exp (0.0045x); R2 = 0.48; p < 0.001). Students with anti-HBV titer higher than 10 mIU/mL (N = 229) were followed up, and anti-HBs IgG titers at follow-up visit linearly correlated with anti-HBV baseline titers (y = 0.86x + 26.2; R2 = 0.67; p < 0.001). A decrease in anti-HBs titers can be expected a few years after the anti-HBV booster dose. This reduction is more pronounced than that observed in students not administered the booster dose and is exponential with respect to basal titers assessed after the booster dose.

Abstract
Hepatitis B (HB) vaccination is the most effective method for preventing HB virus (HBV) infection. Universal HB vaccination containing recombinant HB surface antigens (HBsAg) is recommended. Our data revealed that human monoclonal HB surface antibody (anti-HBs) from individuals inoculated with genotype C-based HB vaccine induced cross-protection against HBV genotype A infection. An in vitro infection model demonstrated anti-HBs-positive sera from individuals inoculated with genotype A- or C-based HB vaccine harbored polyclonal anti-HBs that could bind to non-vaccinated genotype HBV. However, because there were low titers of anti-HBs specific for HBsAg of non-vaccinated genotype, high anti-HBs titers would be required to prevent non-vaccinated genotype HBV infection. Clinically, the 2015 Centers for Disease Control and Prevention guidelines state that periodic monitoring of anti-HBs levels after routine HB vaccination is not needed and that booster doses of HB vaccine are not recommended. However, the American Red Cross suggests that HB-vaccine-induced immune memory might be limited; although HB vaccination can prevent clinical liver injury (hepatitis), subclinical HBV infections of non-vaccinated genotypes resulting in detectable HB core antibody could not be completely prevented. Therefore, monitoring anti-HBs levels after routine vaccination might be necessary for certain subjects in high-risk groups.

Abstract
To evaluate the diagnostic power of red cell distribution width-to-lymphocyte ratio (RLR) for HBV-related liver cirrhosis via a retrospective cohort study.Seven hundred fifty healthy controls, 327 chronic hepatitis B (CHB) patients, and 410 patients with HBV-related liver cirrhosis (HBV-LC) were enrolled in this study. RLR, lymphocyte-to-monocyte ratio (LMR), neutrophil-to-lymphocyte ratio (NLR), red cell distribution width (RDW), AST to platelet ratio index (APRI), and fibrosis index based on the 4 factors (FIB-4) were compared between the 3 groups. The predictive powers of RLR and RDW for HBV-related liver cirrhosis and patient prognosis were evaluated using AUROC.Patients with HBV-related liver cirrhosis had higher RLR, FIB-4, NLR, RDW, APRI, and lower LMR compared with the control and CHB groups. RLR in the HBV-LC group was significantly higher than both CHB and control groups (both P < .05). While RLR in the CHB group was also higher than the control group, the difference was not statistically significant (P > .05). The AUROC of RLR for predicting HBV-related liver cirrhosis was 0.87, and was superior to RDW (0.81), FIB-4 (0.79), and APRI (0.60). With an optimized cut-off value (10.87), RLR had the highest sensitivity (0.88) and specificity (0.72), and was superior to RDW (0.86, 0.64), FIB-4 (0.80, 0.65), and APRI (0.85, 0.48) as a biomarker. For all 3 groups, RLR was negatively correlated (all P < .05) with serum platelet (PLT) and was positively correlated (all P < .05) with FIB-4 and APRI. There was no significant statistical difference in RLR for patients in HBV-LC group who had different prognosis (P > .05).The RLR, a routinely available, inexpensive, and easily calculated measure, can be used as a predictor of HBV-related liver cirrhosis, but not as a predictor of prognosis for patients with liver cirrhosis. Use of RLR may reduce the need for frequent liver biopsies in CHB patients.

Abstract
BACKGROUND Hepatitis B immunoglobulin (HBIG)-as a monotherapy or combined with nucleos(t)ide analogs (NUCs)-has effectively lowered Hepatitis B virus (HBV) reinfection after liver transplantation. However, it is associated with high costs and viral resistance. HBIG-free prophylaxis with novel NUCs (tenofovir, entecavir) composes a viable alternative. We evaluated reinfection rate, histological changes, and outcome associated with HBIG discontinuation. METHODS A retrospective analysis was performed of patients undergoing liver transplantation due to HBV-induced liver disease at our center since 1988. A controlled HBIG discontinuation was conducted between 2015 and 2017 in 65 patients. Recurrent infection was determined by HbsAg values. Fibrosis and inflammation were evaluated by routine biopsy. The survival of patients after HBIG discontinuation was compared to a control population on HBIG for prophylaxis. RESULTS From 1988 to 2013, 352 patients underwent liver transplantation due to HBV-induced liver disease. 169 patients could be included for analysis. 104 (51.5%) patients continued a prophylaxis containing HBIG. HBIG was discontinued in 65 (38.5%) patients in a controlled manner, maintaining an oral NUC. None of those patients showed HBV reinfection or graft dysfunction. No significant changes of inflammation grades (P = .067) or fibrosis stages (P = .051) were detected. The survival of patients after HBIG discontinuation was comparable to the control (P = .95). CONCLUSION HBIG withdrawal under continuation of oral NUC therapy is safe and not related to graft dysfunction, based on blood tests and histology. HBIG-free prophylaxis is not associated with a worse outcome and displays a financial relief as well as a logistic simplification during long-term follow-up.

Abstract
Background Hepatitis B virus (HBV) infection remains a threat to global public health. As a hallmark of HBV infection, hepatitis B surface antigen (HBsAg) has been used to screen for HBV infection for decades, and quantitative assays are also being clinically rejuvenated to predict the disease outcome and monitor the antiviral response. Herein, we developed and evaluated a hook-effect-free homogeneous quantitative HBsAg assay based on the light-initiated chemiluminescence immunoassay (LICA). Methods A hook-effect-free LICA algorithm was established by measuring the relative light units (RLUs) of two time points during the immunoreaction. The precision was assessed using low- and high-level controls. Consecutive clinical serum samples were tested using the LICA and Abbott Architect assay; samples producing inconsistent results were retested using supplementary assays including the HBsAg neutralization, HBV DNA, and Roche Elecsys HBsAg assays for further confirmation. The consistency, sensitivity, specificity, and positive and negative predictive values (PPV and NPV) were calculated. For the quantitative results, the correlation was analyzed. The coverage of different genotypes and mutations by the LICA was evaluated. Moreover, serial on-treatment and follow-up samples from chronic hepatitis B patients were also measured using the two assays. Results The LICA had better within-run and within-laboratory precisions than the Architect assay. In total, 5,176 clinical samples were tested. The two assays showed a consistency of 99.63%. The LICA showed greater specificity (99.95% vs. 99.77%) and PPV (99.75% vs. 98.77%) than the Architect assay, whereas the Architect assay showed greater sensitivity (100.00% vs. 99.01%) and NPV (100.00% vs. 99.82%). The two assays displayed an excellent correlation independent of genotypes and mutations. The LICA hook-free algorithm recognized 100% of the underestimated results. Furthermore, similar HBsAg dynamics were demonstrated using the LICA and Architect HBsAg assay. Conclusions The hook-free LICA provides a reliable tool for screening for HBV infection and quantifying HBsAg.

Abstract
Hepatitis B virus (HBV) is a life-threatening virus that causes very serious liver-related diseases from the family of Hepadnaviridae having very rare qualities resembling retroviruses. In this paper, we analyze the effect of antiviral therapy through mathematical modeling by using Liao's homotopy analysis method (LHAM) that defines the connection between the target liver cells and the HBV. We also examine the basic nonlinear differential equation by LHAM to get a semi-analytical solution. This can be a very straight and direct method which provides the appropriate solution. Moreover, the local and global stability analysis of disease-free and endemic equilibrium is done using Lyapunov function. Mathematica 12 software is used to find out the solutions and graphical representations. We also discuss the numerical simulations up to sixth-order approximation and error analysis using the same software.

Abstract
Background and aims Sustained off-treatment immune control is achievable in a proportion of patients with chronic hepatitis B treated with peginterferon alfa-2a. We evaluated on-treatment predictors of hepatitis B surface antigen (HBsAg) clearance 3 years after peginterferon alfa-2a treatment and determined the incidence of hepatocellular carcinoma. Methods A prospective, international, multicenter, observational study in patients with chronic hepatitis B who have been prescribed peginterferon alfa-2a (40KD) in a real-world setting. The primary endpoint was HBsAg clearance after 3 years’ follow-up. Results The modified intention-to-treat population comprised 844 hepatitis B e antigen (HBeAg)-positive patients (540 [64%] completed 3 years’ follow-up), and 872 HBeAg-negative patients (614 [70%] completed 3 years’ follow-up). At 3 years’ follow-up, HBsAg clearance rates in HBeAg-positive and HBeAg-negative populations, respectively, were 2% (16/844) and 5% (41/872) in the modified intention-to-treat population and 5% [16/328] and 10% [41/394] in those with available data. In HBeAg-positive patients with data, Week 12 HBsAg levels <1500, 1500–20,000, and >20,000 IU/mL were associated with HBsAg clearance rates at 3 years’ follow-up of 11%, 1%, and 5%, respectively (Week 24 predictability was similar). In HBeAg-negative patients with available data, a ≥10% decline vs a <10% decline in HBsAg at Week 12 was associated with HBsAg clearance rates of 16% vs 4%. Hepatocellular carcinoma incidence was lower than REACH-B (Risk Estimation for Hepatocellular Carcinoma in Chronic Hepatitis B) model predictions. Conclusions Sustained off-treatment immune control is achieved with peginterferon alfa-2a in a real-world setting. HBsAg clearance 3 years after completion of peginterferon alfa-2a can be predicted on the basis of on-treatment HBsAg kinetics.

Abstract
OBJECTIVE This article analyzes the effectiveness of a super-accelerated immunization schedule against hepatitis B in patients who have received a liver transplantation. METHODS This is a quantitative and retrospective study based on secondary data of medical records from 177 patients who have received a liver transplantation at the Hospital de Base in São José do Rio Preto, São Paulo State, Brazil, between 1998 and 2016. RESULTS From the total number of participants, 72.89% were male, 39.55% had a cirrhosis diagnosis with associated causes, 23.16% had hepatocellular carcinoma, 53.11% were classified according to Child-Turcotte-Pugh C score, 58.76% had the hepatitis C virus, 97.18% had received an unconventional immunization schedule, and seroconversion was 36.63% among those with an unconventional schedule. The fact that the patient had the hepatitis C virus was statistically significant considering the lack of protection of the vaccine against the hepatitis B virus; their chances were 5 times higher of not seroconverting at the end of the immunization schedule. CONCLUSION The need for high immediate protection in a short term may justify using unconventional immunization schedules in patients who make it to the transplantation waiting list without any previous immunization.

Abstract
BACKGROUND Hepatitis B virus disease is a potentially life-threatening liver infection and a major global health problem. It causes chronic infection and puts people at high risk of death from cirrhosis and liver cancer. WHO estimated 257 million people are living with hepatitis B virus (HBV) infection and in 2015 alone HBV resulted in to 887,000 deaths globally. We determined the prevalence and associated factors of hepatitis B virus infection among Antenatal Care (ANC) attendees in Gamawa Local Government Area, Bauchi State. METHODS We conducted a descriptive cross-sectional, health facility-based study between March and April 2018. We used systematic random sampling technique to recruit 210 pregnant women aged 15-49 years. With a structured questionnaire, we interviewed the respondents and collected blood sample to test for hepatitis B surface antigen. We calculated frequencies, means, proportions, and tested for associations using Epi Info 7.2 and Microsoft Excel. RESULTS The mean age of respondents was 24.5 ± 6.0 years; 112 (53%) of whom were younger than 25 years. All were married, 183 (87%) had no formal education and up to 190 (90%) were employed. Overall, 14 (6.7%) tested positive for HBsAg; women aged ≥35 years had the highest prevalence (10%). None with tertiary education tested positive and women married before 18 years had 13 (6.2%) prevalence. CONCLUSIONS The prevalence of HBsAg among pregnant women in Gamawa LGA was 6.7% which is quite lower than the national prevalence reported. We recommended improved surveillance of HBV infection and screening of women attending ANC.

Abstract
A long-term immunosuppressive treatment can provoke latent infections. Autoimmune blistering diseases (AIBD) are mostly treated with systemic immunosuppressive agents. To prevent the reactivation or exacerbation of existing latent infections, patients must be screened for infectious diseases before immunosuppressive treatments are initiated. However, the prevalence of infectious diseases in AIBD remains to be elucidated. To evaluate the necessity of screening infectious diseases in AIBD, we retrospectively reviewed the clinical records of 215 patients at a single center with AIBD for hepatitis B virus (HBV), hepatitis C virus (HCV), Mycobacterium tuberculosis, Treponema pallidum, human T-cell leukemia virus type 1 (HTLV-1) and HIV infections. Approximately 40% of patients were infected with HBV. During systemic corticosteroid treatment, HBV DNA became positive in 3.4% of cases. Antibodies to HCV, interferon-γ release assays for M. tuberculosis and the T. pallidum latex agglutination test were positive in 0.6%, 6.6% and 1.2% cases, respectively. Neither HTLV-1 nor HIV infections were detected. In conclusion, checks for HBV and M. tuberculosis infections should be made before immunosuppressive treatments are started, because of the high prevalence of these potentially life-threatening infections. Other infections should be tested for depending on the patient's risk factors.

Abstract
Despite the tremendous progresses toward our understanding of the mechanisms of how liver cancer was developed, the therapeutic outcomes of liver cancer in the clinic have very limited improvement within the past three decades or so. In addition, both the incidence and mortality of liver cancer worldwide are not dropping, but increasing steadily, in the last decade. Thus, it is time for us to rethink what has been wrong and how could we do better in the upcoming years, in order to achieve our goal of improving the therapeutic outcomes of patients with liver cancer in the clinic, and at the meantime, effectively reducing the incidence of liver cancer by blocking malignant transformation of hepatocytes from chronic viral infection. This is also one of the main reasons why we try to organize this special issue on primary liver cancer in the journal of Genes & Diseases. In this perspective, I will summarize the major obstacles confronted with in the prevention and management of patients with chronic hepatitis B infection and subsequent development of liver cirrhosis and liver cancer. Next, I will delineate the pitfalls and underlying mechanisms of why the current anti-viral strategies and therapeutic agents are not as effective as one expected in terms of successful reduction or prevention chronic hepatitis B infection associated liver cirrhosis and liver cancer. I will then provide my personal perspectives on potential approaches and strategies for effective prevention and management of hepatitis B-related liver cancer.

Abstract
Objective: To evaluate the cost-effectiveness of the current strategy combining universal vaccination with hepatitis B immunoglobulin (HBIG) treatment for infants of hepatitis B surface antigen (HBsAg) positive mothers compared with universal vaccination with hepatitis B vaccine only.Methods: A decision tree model with a Markov process was constructed and used to simulate the lifetime of the birth cohort in Zhejiang Province during 2016. The current strategy was compared against universal vaccination with respect to costs and health effects. Costs were assessed from the health care system perspective. Health effects were measured by the number of hepatitis B virus (HBV) related diseases and deaths avoided and quality-adjusted life-years (QALYs) gained. The incremental cost‑effectiveness ratio (ICER) is calculated and compared to standard willingness-to-pay thresholds. A one-way sensitivity analysis and a probabilistic sensitivity analysis (PSA) were performed to assess parameter uncertainties.Results: Over the cohort's lifetime, 182 acute symptomatic infections, 2215 chronic infections, 872 cases of cirrhosis, 595 cases of hepatocellular carcinoma (HCC) and 1,350 HBV-related deaths among the cohort of 624,000 infants would be further avoided by the current strategy compared to universal vaccination. Universal vaccination was dominated by the current strategy that produced not only higher total QALYs, but also had lower costs. The results remained robust over a wide range of assumptions.Conclusions: The current strategy was cost saving compared to universal vaccination, and continuing the current strategy is recommended to further decrease the burden of hepatitis B.

Abstract
Plasmacytoid dendritic cells (pDCs) are crucial for control of chronic hepatitis B (CHB) virus infection. In this study, we evaluated the frequencies of pDCs and expression of functional molecules on pDCs in patients treated with PEG-IFN-α-2a or entecavir (ETV) and investigated changes during treatment. The mean fluorescence intensity of CD86 (CD86MFI) on the surface of pDCs and frequencies of pDCs and CD86+ pDCs in peripheral blood were measured. Compared with baseline, CD86+ pDC% and CD86MFI increased obviously after PEG-IFN-α-2a treatment for 12 and 24 weeks. For patients treated with ETV, only pDC% increased observably after treatment weeks 12 and 24 (P < 0.001) compared with baseline. Hepatitis B surface antigen (HBsAg) decline was significantly associated with elevated CD86+ pDC% (r = 0.348, P = 0.015) during PEG-IFN-α-2a treatment. In the HBsAg response group, CD86+ pDC% and CD86MFI (P < 0.001) increased observably after PEG-IFN-α-2a therapy, whereas only CD86MFI had a statistically significant difference after therapy compared with baseline (12 weeks versus 0 weeks, P = 0.022; 24 weeks versus 0 weeks, P = 0.015) in the HBsAg nonresponse group. CD86+ pDC% between the 2 groups had statistically significant differences at baseline (P = 0.001) and at the treatment time points of 12 and 24 weeks (P < 0.001), respectively. For patients receiving ETV therapy, pDC% increased observably, but CD86+ pDC% decreased significantly (P < 0.001) in the HBV DNA nonresponse group during early treatment with ETV. In CHB patients, HBsAg response in PEG-IFN-α-2a therapy correlated with the increase of CD86+ pDC% and HBV DNA nonresponse in ETV treatment correlated with the decrease of CD86+ pDC%.

Abstract
BACKGROUND To prevent the transmission of HIV and hepatitis B and C viruses, early detection is necessary; however, in the early stage, most infected people are symptomless. Screening for these infections should be targeted to certain clinical settings to increase the early detection rate. MATERIAL AND METHODS This retrospective study was conducted by analyzing data from patients' medical records to determine how the screening tests for these viral infections were utilized and what the clinical outcomes from the test utilization were. RESULTS From 11 676 collected records, the screening tests for HIV, HBV, and HCV infections were utilized in 871, 556, and 236 cases, respectively. The tests for HIV and HCV were utilized the most in people with chronic non-infectious diseases, while the test for HBV infection was utilized the most in pregnant women. The positive results of these tests were highly found in the group of patients with acute non-infectious diseases. HIV infection was newly detected in 1.38% of patients, and HBV and HCV infections were newly detected in 5.58% and 2.12%, respectively. CONCLUSIONS Screening for HIV and HBV infections was performed according to the guidelines of the national HIV and HBV programs. The Outpatient Department (OPD) and medical ward may be the most appropriate clinical settings for HIV screening because most patients are there and blood tests are often ordered there, too. The national programs helped slow the rates of HIV and HBV infections in this community.

Abstract
Objectives: Hepatitis B is a viral infection primarily affecting people from culturally diverse communities in Australia. While vaccination prevents infection, there is increasing mortality resulting from liver damage associated with chronic infection. Deficits in the national policy and clinical response to hepatitis B result in a low diagnosis rate, inadequate testing and diagnosis processes, and poor access to hepatitis B treatment services. While research identifies inadequate hepatitis B knowledge among people with the virus and primary health care workers, this project sought to identify how specialist clinicians in Australia negotiate cultural diversity, and provide often complex clinical information to people with hepatitis B. Design: A vignette was developed and presented to thirteen viral hepatitis specialist clinicians prior to an electronically recorded interview. Recruitment continued until saturation of themes was reached. Data were thematically coded into themes outlined in the interview schedule. Ethical approval for the research was provided by the La Trobe University Human Research Ethics Committee. Results: Key messages provided to patients with hepatitis B by clinical specialists were identified. These messages were not consistently provided to all patients with hepatitis B, but were determined on perceptions of patient knowledge, age and highest educational level. While the vignette stated that English was not an issue for the patient, most specialists identified the need for an interpreter. Combating stigma related to hepatitis B was seen as important by the specialists and this was done through normalising the virus. Having an awareness of different cultural understandings about hepatitis B specifically, and health and well-being generally, was noted as a communication strategy. Conclusion: Key core competencies need to be developed to deliver educational messages to people with hepatitis B within clinical encounters. The provision of adequate resources to specialist clinics will assist in addressing gaps in the clinical response to hepatitis B.

Abstract
BACKGROUND High genetic variability at the reverse transcriptase (RT) region of HBV could confer resistance to nucleoside/nucleotide analogues (NUCs). The aim of this study was to identify new RT amino acid (AA) substitutions related to NUC resistance. METHODS HBV RT sequences of genotype C from 501 chronic hepatitis B (CHB) patients were analysed to identify potential RT substitutions related to NUC resistance. In vitro studies without and with NUCs were performed in a HepG2 cell line transfected by clones with RT harbouring wild-type or substituted AA(s) of interest. RESULTS Among 261 NUC-treated CHB patients, we found a high detection rate of rtM204I/V substitution (30.7% [80/261]). We identified a new substitution of rtH55R, and its detection rate had a significantly increasing trend from 3.8% (9/240) in the untreated group to 7.2% (13/181) or 33.8% (27/80) in the treated group with rtM204 or with rtM204I/V substitutions (P<0.0001). In vitro studies showed that rtH55R had a similar HBV DNA level compared to wild type. The rtH55R+rtM204I clone had a significantly better replication capacity than the rtM204I clone without NUCs (P<0.05). The replication capacity of the rtM204I clone was found to significantly decrease under lamivudine treatment, but this was not found in the rtH55R+rtM204I clone. CONCLUSIONS We identified a new HBV RT substitution of rtH55R in genotype-C-infected CHB patients. It is frequently found in combination with rtM204I/V substitution under NUC treatment. In vitro studies suggest that it might play some replication compensatory role in rtM204I mutants under lamivudine treatment.

Abstract
Objective Since healthcare providers face an increased risk of hepatitis B virus (HBV) infection because of their work, vaccination plays a critical role in preventing HBV transmission. However, the duration for which acquired HBV surface antibodies (anti-HBs) persist remains unknown. To evaluate the primary immunologic response to HBV vaccination and its persistence in healthy Japanese adolescents. Methods In total, 690 young adults underwent HBV vaccination with a three-dose schedule. The primary response was determined by the anti-HBs titers at 1-2 months after the final dosage. Subjects with anti-HBs titers of <10, 10-100, and >100 mIU/mL were classified as "non-responders," "low-responders," and "sufficient responders," respectively. Anti-HB titers were re-measured at 1 or 2 years after vaccination. Results First, 95.8% and 72.8% of the subjects had anti-HBs titers of >10 and >100 mIU/mL, respectively, as a primary response. The anti-HBs titers measured at 1 and 2 years after vaccination were significantly correlated with those of the primary response (1 year: r=0.893, p<0.0001; 2 years: r=0.902, p<0.001). Most subjects with a titer of >100 mIU/mL at the primary response maintained an anti-HBs titer of >10 mIU/mL [1 year after vaccination, 208/209 (99.5%); 2 years after vaccination, 72/81 (90.1%)]. However, in subjects with a primary response of 10-100 mIU/mL the anti-HBs titer frequently declined; 17/38 (44.7%) and 9/10 (90.0%) subjects had a titer of <10 mIU/mL at 1 and 2 years, respectively. Conclusion The primary response was associated with the anti-HBs titers at 1 and 2 years after vaccination, and the anti-HBs titers of 54.2% of the low responders were not maintained for 2 years, even if they were vaccinated as healthy young adults.

Abstract
To study the efficacy of a polyoxometalate, Cs2 K4 Na[SiW9 Nb3 O40 ]·H2 O, as an antiviral treatment in HBV transgenic mice. HBV transgenic mice were treated with Cs2 K4 Na[SiW9 Nb3 O40 ]·H2 O by intragastric administration. Adefovir and distilled water were administered as controls. Serum HBV DNA, liver HBV RNA levels were measured by quantitative RT-PCR. Serum HBsAg levels were measured by ELISA. The hepatitis B virus surface antigen (HBsAg) in liver cells was detected by immunohistochemistry (IHC). Pathological changes in the liver tissues were also observed by light and electron microscopy. Cs2 K4 Na[SiW9 Nb3 O40 ]·H2 O significantly decreased serum HBsAg and HBV DNA levels. Cs2 K4 Na[SiW9 Nb3 O40 ]·H2 O resulted in a 98% decrease in serum HBV DNA at 28 days, from 4.3 log10 copies/ml at baseline to 2.5 log10 copies/ml after treatment, and the inhibition rate of HBV DNA was higher than ADV at the same dose. The HBV replication levels in each group slightly increased at 7 days after withdrawal, but rebounded slightly more in the Cs2 K4 Na[SiW9 Nb3 O40 ]·H2 O treatment group compared to the H2 O control group (p < .05). There were no differences in HBV RNA levels. No significant differences were observed in the pathology, but there were decreased HBsAg levels in the Cs2 K4 Na[SiW9 Nb3 O40 ]·H2 O-treated group compared to the control group. The results demonstrated that Cs2 K4 Na[SiW9 Nb3 O40 ]·H2 O displayed potent anti-HBV activity in HBV transgenic mice and supported for future clinic study.

Abstract
Background Many people with chronic liver disease (CLD) are not detected until they present to hospital with advanced disease, when opportunities for intervention are reduced and morbidity is high. In order to build capacity and liver expertise in the community, it is important to focus liver healthcare resources in high-prevalence disease areas and specific populations with an identified need. The aim of the present study was to examine the geographic location of people seen in a tertiary hospital hepatology clinic, as well as ethnic and sociodemographic characteristics of these geographic areas. Methods The geographic locations of hepatology out-patients were identified via the out-patient scheduling database and grouped into statistical area (SA) regions for demographic analysis using data compiled by the Australian Bureau of Statistics. Results During the 3-month study period, 943 individuals from 71 SA Level 3 regions attended clinic. Nine SA Level 3 regions accounted for 55% of the entire patient cohort. Geographic clustering was seen especially for people living with chronic hepatitis B virus. There was a wide spectrum of socioeconomic advantage and disadvantage in areas with high liver disease prevalence. Conclusions The geographic area from which people living with CLD travel to access liver health care is extensive. However, the greatest demand for tertiary liver disease speciality care is clustered within specific geographic areas. Outreach programs targeted to these areas may enhance liver disease-specific health service resourcing. What is known about the topic? The demand for tertiary hospital clinical services in CLD is rising. However, there is limited knowledge about the geographic areas from which people living with CLD travel to access liver services, or the ethnic, socioeconomic and education characteristics of these areas. What does this paper add? The present study demonstrates that a substantial proportion of people living with CLD and accessing tertiary hospital liver services are clustered within specific geographic areas. The most striking geographic clustering was seen for people living with chronic hepatitis B, in regions with a relatively high proportion of people born in Vietnam and China. In addition to ethnicity, the data show an apparent ecological association between liver disease and both socioeconomic and educational and/or occupational disadvantage. What are the implications for practitioners? Identifying where demand for clinical services arises is an important step for service planning and preparing for potential outreach programs to optimise community-based care. It is likely that outreach programs to engage and enhance primary care services in geographic areas from which the greatest demand for tertiary liver disease speciality care arises would yield greater relative return on investment than non-targeted outreach programs.

Abstract
Hepatitis B virus infection is the cause of liver diseases such as cirrhosis and liver cancer. Understanding the host-virus mechanisms that mediate virus pathogenesis can help design better preventive measures for disease control. Mathematical models have been used alongside experimental data to provide insight into the role of immune responses during the acute and chronic hepatitis B infections as well as virus dynamics following administration of combined drug therapy. In this paper, we review several modeling studies on virus-host interactions during acute infection, the virus-host characteristics responsible for transition to chronic disease, and the efficacy and optimal control measures of drug therapy. We conclude by presenting our opinion on the future directions of the field.

Abstract
Medical residents (MRs) are healthcare workers (HCWs) who are likely to be exposed to blood-borne pathogens such as hepatitis B virus (HBV). A total of 220 (100%) MRs from Catania University Hospital (Italy) were enrolled for a seroprevalence study in the framework of occupational surveillance in order to evaluate HBV vaccination coverage. For each MR, Hepatitis B surface antigen (HbsAg), Hepatitis B surface antibody (HBsAb), Hepatitis B core antiboy (HbcAb), Hepatitis C antibody (HCV-Ab) and HIV antibody (HIV-Ab) were assessed. No one was found to be positive for: HbsAg, HbcAb, HCV-Ab or HIV-Ab. HBV vaccination coverage was found in 80% of those tested. A total of 45 MRs showed a nonprotective antibody titer; in eight, complete vaccination had never been carried out; in 37, the vaccination had been carried out, but the antibody titer was not protective. This research showed high adherence to HBV vaccination; however, the vaccine coverage of HCWs is still suboptimal. Vaccinations for HCWs should be made mandatory.

Abstract
BACKGROUND AND AIMS The prevalence of chronic hepatitis B virus (HBV) infection in Europe is poorly defined. Data on the proportion of patients eligible for therapy are lacking but are crucial to meet WHO elimination goals. The aims of our study were to provide an estimate of the need for antiviral treatment and to assess the prevalence of advanced liver disease in treatment-naive, chronic HBV-infected patients. PATIENTS AND METHODS We performed a retrospective, cross-sectional analysis of all treatment-naive HBV-infected patients. Baseline clinical assessments included sociodemographic data, hepatitis B-specific analyses, and liver stiffness measurement (LSM). RESULTS Between 2010 and 2017, 465 patients with chronic HBV infection were referred, with 301 (64.7%) being eligible for our analysis. Overall, 40% were female, and the mean age was 39.3±13.1 years. Moreover, 61% of patients were born outside Europe, predominantly in the Asia-Pacific region. The median HBV viral load was 1630 IU/ml (interquartile range: 240-35 000 IU/ml), 145 (48.2%) patients had an HBV viral load above 2000 IU/ml, and 14.3% were HBeAg positive.Median LSM was 5.2 kPa (interquartile range: 4.2-6.6 kPa). LSM indicating clinically significant fibrosis (≥F2) was found in 96/271 (35.0%) patients, including 20/271 (7.4%) patients with suspected advanced fibrosis/cirrhosis. Overall, 26% of patients met EASL 2017 treatment criteria. CONCLUSION In HBV-infected patients referred to one of the largest ID clinics in Berlin, only 26% met EASL treatment criteria and 7% had suspected cirrhosis at presentation. Only in 4% of all patients, a treatment indication could not be determined by a noninvasive approach.

Abstract
Chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infection are the most important underlying causes for the development of hepatocellular carcinoma (HCC) worldwide. Determining the optimal approach for management of the viral infection and the HCC depends on the virus and the stage of the cancer. In patients with HCV-associated HCC, there are multiple reasons to first treat the HCC. Firstly, in case of a curable HCC, the urgency for HCC treatment is important to avoid progression during HCV treatment. Secondly, the presence of HCC itself appears to reduce the rates of sustained virological response (SVR) achieved with direct-acting antivirals (DAAs). And finally, the evidence does not support the concept of an increase in HCC recurrence due to DAAs, so a patient can safely be treated after HCC cure. For patients with very advanced HCC, the benefits of HCV therapy are questionable. In contrast, those who develop HCC in the setting of chronic HBV infection, treatment with nucleoside analogues (NAs) is recommended prior to treating HCC, to prevent further liver injury and reduce the risk for HCC recurrence. Ultimately, earlier diagnosis and treatment of HBV and HCV will hopefully reduce the incidence of HCC worldwide.

Abstract
BACKGROUND AND AIMS Acute-on-chronic liver failure (ACLF) can be triggered by reactivation of chronic hepatitis B (CHB). Tenofovir disoproxil fumarate (TDF) and entecavir (ETV) are now the most potent antiviral agents for CHB. This study aimed to compare the short-term safety and efficacy of TDF with ETV in the treatment of ACLF due to reactivation of CHB [hepatitis B virus (HBV)-ACLF]. PATIENTS AND METHODS In total, 67 consecutive patients with HBV-ACLF were divided into TDF group (n=32) receiving daily TDF (300 mg/d) and ETV group (n=35) receiving daily ETV (0.5 mg/d). They were prospectively followed-up and the primary endpoint was overall survival at 3 months. RESULTS At 2 weeks, the TDF group had significantly higher HBV-DNA reduction (P=0.003), lower HBV-DNA level (P=0.001), higher rate of HBV-DNA undetectbility (P=0.007), lower Child-Turcotte-Pugh (CTP; P=0.003), and model for end-stage liver disease (P=0.002) scores than the ETV group. At 3 months, HBV-DNA was undetectable in all survived patients; CTP (P=0.970) and model for end-stage liver disease (P=0.192) scores were comparable between the 2 groups, but markedly lower than at baseline (P<0.01); the TDF group had significantly higher cumulative survival rate than the ETV group (P=0.025). The white blood cell count (hazard ratio, 2.726; 95% confidence interval, 2.691-7.897; P=0.000), and HBV-DNA reduction (hazard ratio, 0.266; 95% confidence interval, 0.033-0.629; P=0.013) at 2 weeks were independent predictors for mortality. Both drugs were well tolerated. CONCLUSIONS The short-term efficacy of TDF was superior to ETV for the treatment of HBV-ACLF. The white blood cell count and HBV-DNA reduction at 2 weeks were independent predictors for mortality at 3 months.

Abstract
As hepatocellular carcinoma (HCC) usually occurs in the background of cirrhosis, which is an end-stage form of liver diseases, treatment options for advanced HCC are limited, due to poor liver function. The exosome is a nanometer-sized membrane vesicle structure that originates from the endosome. Exosome-mediated transfer of proteins, DNAs and various forms of RNA, such as microRNA (miRNA), long noncoding RNA (lncRNA) and messenger RNA (mRNA), contributes to the development of HCC. Exosomes mediate communication between both HCC and non-HCC cells involved in tumor-associated cells, and several molecules are implicated in exosome biogenesis. Exosomes may be potential diagnostic biomarkers for early-stage HCC. Exosomal proteins, miRNAs and lncRNAs could provide new biomarker information for HCC. Exosomes are also potential targets for the treatment of HCC. Notably, further efforts are required in this field. We reviewed recent literature and demonstrated how useful exosomes are for diagnosing patients with HCC, treating patients with HCC and predicting the prognosis of HCC patients.

Abstract
As the global population ages, there is concern about the effect of an increased proportion of older individuals on the economic sustainability of healthcare systems and the social effects of an older society. Health authorities and advocacy groups in countries at the forefront of this trend are now developing strategies to ameliorate the social and financial effects of an ageing population. There is broad agreement that for both society and for the individuals, it is important to ensure that increasing lifespans are matched with increased "healthspans" - the number of years spent in good health. There is also growing consensus that vaccination is one of the tools that can play an important role in improving adult health - though currently vaccination coverage is often poor. This review focuses on two issues that consistently appear to be associated with under-vaccination: the low awareness of risk (and potential consequences) for vaccine-preventable diseases and a poor understanding of the value of improved vaccination coverage for adults. We suggest that understanding of vaccination as a health-promoting activity, rather than a medical intervention designed to prevent the spread of a specific pathogen - is a crucial step to improve vaccination uptake among adults (see Supplementary video abstract ). Key messages As populations age globally, we are seeing an increasing burden of vaccine-preventable disease in adults. Adult vaccination against some common diseases has been shown to dramatically improve health and quality of life for older people. Despite the attested benefits, vaccination coverage is almost always poor in adults, even in countries where access is free at point of care. In this article, we discuss what appears to a neglected issue in adult vaccination, that of personal autonomy. We argue that adult vaccination will only be successful if it respects individual autonomy and that this requires treating the choice to vaccinate as a public health issue akin to smoking cessation, exercise and healthy diet.

Abstract
Chronic hepatitis B (CHB) is a major global health burden. Liver fibrosis, an insidious process, is the main histopathological change in CHB that might lead to the end-stage liver disease if left untreated. The intermediate liver fibrosis (S2) is the optimal time to start antiviral therapy. The aim of the present study was to examine the proteomic changes in patients with CHB at different fibrotic stages, with a view to identify future serum biomarkers for S2. Ninety CHB patients were grouped into mild (S0-1), intermediate (S2), and severe liver fibrosis (S3-4) (61 men and 29 women; age 25-63 years). Isobaric tagging for relative and absolute quantitation was applied to screen proteins differentially expressed among the patient groups. Another 46 patients with CHB (age 25-59 years; 31 men and 15 women), and 16 healthy controls (age 26-61 years; 11 men and 5 women) were enrolled in a validation group. Enzyme-linked immunosorbent assay was used to verify the diagnostic value of the candidate biomarkers. We found 139 proteins that were differentially expressed between various fibrotic stage-paired comparisons. Five protein candidates were selected as potential biomarkers of S2 for further verification. Notably, ficolin-2 (FCN2) and carboxypeptidase B2 (CPB2) showed differential expression between patients and healthy controls. In conclusion, serum proteomic changes reported here offer new molecular leads for future research on biomarker candidates to identify liver fibrotic stages in CHB. In particular, FCN2 and CPB2 warrant further research on their possible mechanistic involvement in CHB pathogenesis.

Abstract
AIM The consideration of patients' needs in terms of research outcomes is emphasized in research promotion to eradicate hepatitis B virus according to the Basic Act on Hepatitis Measures in Japan. This study analyzed patients' attitudes toward experienced antiviral therapies for chronic hepatitis B and their need for future therapies. METHODS A self-administered questionnaire comprising 124 questions was completed among patients with chronic hepatitis B from 61 core-center hospitals designated to implement and research policies on hepatitis in 47 prefectures from August 2013 to January 2014 (n = 3021, response rate = 51%). RESULTS In decision-tree models with 333 variables generated from the questionnaire data, patients' satisfaction with therapy and reduction in anxiety about therapy were dependent on favorable therapeutic effects, sufficient information provided by the physician, and fewer lifestyle disturbances. Medical expenses were not selected at a superior branch because subsidy for antiviral therapy started in 2010. In correspondence analysis of free text answers, patients' need for therapy and support mechanisms differed among their attributes, including a great need for novel therapy in older men, hope for avoidance of lifestyle disturbance in younger men, and alleviation of painful experience with the disease in women. CONCLUSIONS Continual provision of sufficient information is necessary to improve the utility of antiviral therapy for chronic hepatitis B as well as for favorable therapeutic effects. The patients believed that novel drugs and support would reduce the diverse burden of the disease on their lives.

Abstract
Background Acute-on-chronic liver failure (ACLF) can be caused by reactivation of chronic hepatitis B virus (HBV) infection (HBV-ACLF). It’s unclear whether HBV genotypes affect the clinical and therapeutical outcomes of patients with HBV-ACLF. This study was to investigate the short-term antiviral response and overall survival in HBV-ACLF patients treated by tenofovir or entecavir. Methods Seventy-three consecutive patients with HBV-ACLF were stratified into genotype B group (n = 33) and C group (n = 40). They were prospectively followed-up. Results At 2 weeks, the genotype B group had significantly lower HBV-DNA load (P = 0.005), greater HBV-DNA decline (P = 0.026), higher proportion of patients with HBV-DNA < 500 IU/ml (P = 0.007), improved Child-Turcotte-Pugh (CTP; P = 0.032) and model for end-stage liver disease (MELD; P = 0.039) scores compared to the genotype C group. At three months, survivors in both groups had undetectable HBV-DNA loads, comparable CTP (P = 0.850) and MELD (P = 0.861) scores; the genotype C group had markedly lower overall survival rate than the B group (P = 0.013). The genotype (hazard ratio [HR]: 2.138; 95% confidence interval [CI]: 1.034–4.143; P = 0.041), MELD score (HR:1.664, 95%CI: 1.077–2.571; P = 0.022) and HBV-DNA decline (HR: 0.225, 95% CI: 0.067–0.758; P = 0.016) at 2 weeks were significantly associated with mortality at 3 months. No severe adverse event was noted. Conclusions Genotype B was associated with better short-term antiviral response and clinical outcome compared to genotype C in patients with HBV-ACLF.

Lancet 2018; 392:1789-1858. [PMID: 30496104 PMCID: PMC6227754 DOI: 10.1016/s0140-6736(18)32279-7] [Citation(s) in RCA: 7199] [Impact Index Per Article: 1199.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/09/2018] [Revised: 08/30/2018] [Accepted: 09/12/2018] [Indexed: 02/06/2023]
Abstract
BACKGROUND The Global Burden of Diseases, Injuries, and Risk Factors Study 2017 (GBD 2017) includes a comprehensive assessment of incidence, prevalence, and years lived with disability (YLDs) for 354 causes in 195 countries and territories from 1990 to 2017. Previous GBD studies have shown how the decline of mortality rates from 1990 to 2016 has led to an increase in life expectancy, an ageing global population, and an expansion of the non-fatal burden of disease and injury. These studies have also shown how a substantial portion of the world's population experiences non-fatal health loss with considerable heterogeneity among different causes, locations, ages, and sexes. Ongoing objectives of the GBD study include increasing the level of estimation detail, improving analytical strategies, and increasing the amount of high-quality data. METHODS We estimated incidence and prevalence for 354 diseases and injuries and 3484 sequelae. We used an updated and extensive body of literature studies, survey data, surveillance data, inpatient admission records, outpatient visit records, and health insurance claims, and additionally used results from cause of death models to inform estimates using a total of 68 781 data sources. Newly available clinical data from India, Iran, Japan, Jordan, Nepal, China, Brazil, Norway, and Italy were incorporated, as well as updated claims data from the USA and new claims data from Taiwan (province of China) and Singapore. We used DisMod-MR 2.1, a Bayesian meta-regression tool, as the main method of estimation, ensuring consistency between rates of incidence, prevalence, remission, and cause of death for each condition. YLDs were estimated as the product of a prevalence estimate and a disability weight for health states of each mutually exclusive sequela, adjusted for comorbidity. We updated the Socio-demographic Index (SDI), a summary development indicator of income per capita, years of schooling, and total fertility rate. Additionally, we calculated differences between male and female YLDs to identify divergent trends across sexes. GBD 2017 complies with the Guidelines for Accurate and Transparent Health Estimates Reporting. FINDINGS Globally, for females, the causes with the greatest age-standardised prevalence were oral disorders, headache disorders, and haemoglobinopathies and haemolytic anaemias in both 1990 and 2017. For males, the causes with the greatest age-standardised prevalence were oral disorders, headache disorders, and tuberculosis including latent tuberculosis infection in both 1990 and 2017. In terms of YLDs, low back pain, headache disorders, and dietary iron deficiency were the leading Level 3 causes of YLD counts in 1990, whereas low back pain, headache disorders, and depressive disorders were the leading causes in 2017 for both sexes combined. All-cause age-standardised YLD rates decreased by 3·9% (95% uncertainty interval [UI] 3·1-4·6) from 1990 to 2017; however, the all-age YLD rate increased by 7·2% (6·0-8·4) while the total sum of global YLDs increased from 562 million (421-723) to 853 million (642-1100). The increases for males and females were similar, with increases in all-age YLD rates of 7·9% (6·6-9·2) for males and 6·5% (5·4-7·7) for females. We found significant differences between males and females in terms of age-standardised prevalence estimates for multiple causes. The causes with the greatest relative differences between sexes in 2017 included substance use disorders (3018 cases [95% UI 2782-3252] per 100 000 in males vs s1400 [1279-1524] per 100 000 in females), transport injuries (3322 [3082-3583] vs 2336 [2154-2535]), and self-harm and interpersonal violence (3265 [2943-3630] vs 5643 [5057-6302]). INTERPRETATION Global all-cause age-standardised YLD rates have improved only slightly over a period spanning nearly three decades. However, the magnitude of the non-fatal disease burden has expanded globally, with increasing numbers of people who have a wide spectrum of conditions. A subset of conditions has remained globally pervasive since 1990, whereas other conditions have displayed more dynamic trends, with different ages, sexes, and geographies across the globe experiencing varying burdens and trends of health loss. This study emphasises how global improvements in premature mortality for select conditions have led to older populations with complex and potentially expensive diseases, yet also highlights global achievements in certain domains of disease and injury.

Abstract
BACKGROUND The Global Burden of Diseases, Injuries, and Risk Factors Study 2017 (GBD 2017) includes a comprehensive assessment of incidence, prevalence, and years lived with disability (YLDs) for 354 causes in 195 countries and territories from 1990 to 2017. Previous GBD studies have shown how the decline of mortality rates from 1990 to 2016 has led to an increase in life expectancy, an ageing global population, and an expansion of the non-fatal burden of disease and injury. These studies have also shown how a substantial portion of the world's population experiences non-fatal health loss with considerable heterogeneity among different causes, locations, ages, and sexes. Ongoing objectives of the GBD study include increasing the level of estimation detail, improving analytical strategies, and increasing the amount of high-quality data. METHODS We estimated incidence and prevalence for 354 diseases and injuries and 3484 sequelae. We used an updated and extensive body of literature studies, survey data, surveillance data, inpatient admission records, outpatient visit records, and health insurance claims, and additionally used results from cause of death models to inform estimates using a total of 68 781 data sources. Newly available clinical data from India, Iran, Japan, Jordan, Nepal, China, Brazil, Norway, and Italy were incorporated, as well as updated claims data from the USA and new claims data from Taiwan (province of China) and Singapore. We used DisMod-MR 2.1, a Bayesian meta-regression tool, as the main method of estimation, ensuring consistency between rates of incidence, prevalence, remission, and cause of death for each condition. YLDs were estimated as the product of a prevalence estimate and a disability weight for health states of each mutually exclusive sequela, adjusted for comorbidity. We updated the Socio-demographic Index (SDI), a summary development indicator of income per capita, years of schooling, and total fertility rate. Additionally, we calculated differences between male and female YLDs to identify divergent trends across sexes. GBD 2017 complies with the Guidelines for Accurate and Transparent Health Estimates Reporting. FINDINGS Globally, for females, the causes with the greatest age-standardised prevalence were oral disorders, headache disorders, and haemoglobinopathies and haemolytic anaemias in both 1990 and 2017. For males, the causes with the greatest age-standardised prevalence were oral disorders, headache disorders, and tuberculosis including latent tuberculosis infection in both 1990 and 2017. In terms of YLDs, low back pain, headache disorders, and dietary iron deficiency were the leading Level 3 causes of YLD counts in 1990, whereas low back pain, headache disorders, and depressive disorders were the leading causes in 2017 for both sexes combined. All-cause age-standardised YLD rates decreased by 3·9% (95% uncertainty interval [UI] 3·1-4·6) from 1990 to 2017; however, the all-age YLD rate increased by 7·2% (6·0-8·4) while the total sum of global YLDs increased from 562 million (421-723) to 853 million (642-1100). The increases for males and females were similar, with increases in all-age YLD rates of 7·9% (6·6-9·2) for males and 6·5% (5·4-7·7) for females. We found significant differences between males and females in terms of age-standardised prevalence estimates for multiple causes. The causes with the greatest relative differences between sexes in 2017 included substance use disorders (3018 cases [95% UI 2782-3252] per 100 000 in males vs s1400 [1279-1524] per 100 000 in females), transport injuries (3322 [3082-3583] vs 2336 [2154-2535]), and self-harm and interpersonal violence (3265 [2943-3630] vs 5643 [5057-6302]). INTERPRETATION Global all-cause age-standardised YLD rates have improved only slightly over a period spanning nearly three decades. However, the magnitude of the non-fatal disease burden has expanded globally, with increasing numbers of people who have a wide spectrum of conditions. A subset of conditions has remained globally pervasive since 1990, whereas other conditions have displayed more dynamic trends, with different ages, sexes, and geographies across the globe experiencing varying burdens and trends of health loss. This study emphasises how global improvements in premature mortality for select conditions have led to older populations with complex and potentially expensive diseases, yet also highlights global achievements in certain domains of disease and injury.

Abstract
The hepatitis B virus (HBV) is a preventable infection that can lead to chronic HBV and liver cancer without timely detection and treatment. The Hepatitis B Foundation is a national organization that helps coordinate local coalitions that work at the community level. The Hepatitis B Foundation website ( http://www.hepb.org/ ) serves as an interactive, educational website for patients, informal caregivers (e.g., family members), physicians, and community stakeholders such as local/regional health organizations and community coalitions. The multifaceted site provides user-friendly resources and tools that are available in several different languages to reach the global HBV patient population. Topic-delimited tabs (i.e., “What Is Hepatitis B?,” “Prevention & Diagnosis,” “Treatment & Management,” “Resources & Support,” “Research & Programs,” and “News & Events”) keep web content organized and easy to browse. The website also provides interactive tools such as blogs and social media campaigns that support peer-to-peer engagement. Additionally, the website stresses the importance of HBV prevention using resources on primary, secondary, and tertiary prevention. Overall, the website is a very useful tool for anyone seeking more information on topics related to HBV prevention, diagnosis, and treatment.

Novel Potent Capsid Assembly Modulators Regulate Multiple Steps of the Hepatitis B Virus Life Cycle. Antimicrob Agents Chemother 2018; 62:AAC.00835-18. [PMID: 30012770 DOI: 10.1128/aac.00835-18] [Citation(s) in RCA: 72] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2018] [Accepted: 07/10/2018] [Indexed: 02/07/2023] Open
Abstract
The assembly of hepatitis B virus (HBV) core protein (HBc) into capsids represents a critical step of viral replication. HBc has multiple functions during the HBV life cycle, which makes it an attractive target for antiviral therapies. Capsid assembly modulators (CAMs) induce the formation of empty capsid or aberrant capsid devoid of pregenomic RNA (pgRNA) and finally block relaxed circular DNA neosynthesis and virion progeny. In this study, the novel CAMs JNJ-827 and JNJ-890 were found to be potent inhibitors of HBV replication with respective half-maximal effective concentrations of 4.7 and 66 nM, respectively, in HepG2.117 cells. Antiviral profiling in differentiated HepaRG (dHepaRG) cells and primary human hepatocytes revealed that these compounds efficiently inhibited HBV replication, as well as de novo establishment of covalently closed circular DNA (cccDNA). In addition to these two known effects of CAMs, we observed for the first time that a CAM, here JNJ-827, when added postinfection for a short-term period, significantly reduced hepatitis B e antigen (HBeAg) secretion without affecting the levels of cccDNA amount, transcription, and hepatitis B surface antigen (HBsAg) secretion. This inhibitory activity resulted from a direct effect of JNJ-827 on HBeAg biogenesis. In a long-term treatment condition using persistently infected dHepaRG cells, JNJ-827 and JNJ-890 reduced HBsAg concomitantly with a decrease in viral total RNA and pgRNA levels. Altogether, these data demonstrate that some CAMs could interfere with multiple functions of HBc in the viral life cycle.

Abstract
BACKGROUND Hepatitis B is the most common occupational disease in health care providers. It can be followed by several complications. The aim of this study was to determine the cognitive determinants of hepatitis B (HB) vaccination Acceptability among nurses based on the Health Belief Model (HBM). METHODS This cross-sectional study was conducted among 330 nurses in educational hospitals of Kermanshah city, during 2016. Samples were randomly selected with the proportional to size among different educational hospitals in Kermanshah. A structured questionnaire was applied for collecting data and data were analyzed using SPSS software version 16 by using bivariate correlations and logistic regression statistical tests. RESULTS The mean age of the respondents was 30.5 years [SD: 6.62]. About, 58.5% of the participants reported to have completed (three times) vaccination of HB. Female nurses were more likely to be fully vaccinated against HB than male nurses, with adjusted odds ratio estimate of 2.507 [95% CI: 1.523-4.125] and those who had family or friends with a history of HB with odds ratio estimate of 3.706 [95% CI: 1.317-10.425], making these the most influential predictive determinants for full uptake (three time) of HB vaccination. Among the HBM variables: perceived threat with odds ratio estimate of 1.264 [95% CI: 1.160-1.376], perceived self-efficacy with odds ratio estimate of 1.179 [95% CI: 1.020-1.363], and cues to action with odds ratio estimate of 1.335 [95% CI: 1.015-1.756], were the more influential predictors of full uptake (three time) of HB vaccination. CONCLUSION To development uptake vaccination programs promotion in addition to focusing on male nurses, using the results of the predictive constructs include; perceived threat perceived self-efficacy suggested. Based on our result, it seems that development and implementation of health promotion programs to increase threat about side effect of HB and self-efficacy regarding HB vaccination uptake may be usefulness of the findings to promotion of vaccination of HB.

Abstract
Elimination of the three blood-borne viruses—human immunodeficiency virus (HIV), hepatitis B (HBV) and hepatitis C (HCV)—as public health issues may be plausible in the near future. Spectacular advances have been made with the introduction of highly effective antiviral agents into clinical practice, and prevention strategies are available for all three infections. Effective disease control, laid out by WHO global strategies, is currently feasible for all three viruses. However, for worldwide elimination of these viruses, effective vaccines are required that are currently only available for HBV. In this review differences and parallels among HIV, HCV and HBV will be discussed with a focus on virologic and therapeutic issues, and prospects for the future of HBV will be presented.

Abstract
Nature killer (NK) cells play a critical role in host innate and adaptive immune defense against viral infections and tumors. NK cells are enriched in liver hematopoietic cells with unique NK repertories and functions to safeguard liver cells against hepatitis virus infection or malignancy transformation. However, accumulating evidences were found that the NK cells were modulated by liver diseases and liver cancers including hepatocellular carcinoma (HCC) and showed impaired functions failing to activate the elimination of the viral-infected cells or tumor cells and were further involved in the pathogenesis of liver injury and inflammation. The full characterization of circulation and intrahepatic NK cell phenotype and function in liver disease and liver cancer has not only provided new insight into the disease pathogenesis but has also discovered new targets for developing new NK cell-based therapeutic strategies. This review will discuss and summarize the NK cell phenotypic and functional changes in liver disease and HCC, and the NK cell-based immunotherapy approaches and progresses for cancers including HCC will also be reviewed.

Abstract
Background Hepatitis B virus (HBV) infection causes acute and chronic liver diseases that can eventually develop into cirrhosis and hepatocellular carcinoma (HCC), but the carcinogenesis of HBV is not fully understood. Carboxyl-terminal-binding protein 2 (CtBP2) plays an important role in tumorigenesis and progression. The aim of this study was to investigate the effect of HBV on CtBP2 expression and to explore its mechanism. Methods Real-time quantitative reverse transcription polymerase chain reaction (RT-qPCR) and western blotting were used to evaluate the CtBP2 mRNA and protein expression levels in tissues and cells. The HBV infectious clone pHBV1.3 and plasmids expressing a single gene of the HBV genome were cotransfected with the CtBP2 gene promoter pGL3-CtBP2 into the human hepatoma cell line HepG2, and luciferase activity was determined using a luminometer. Results CtBP2 expression was higher in HBV-related HCC tissues than in paracancerous tissues. CtBP2 expression was higher in HepG2.2.15 cells integrated with the HBV genome than in HepG2 cells. pHBV1.3 upregulated CtBP2 mRNA and protein expression. The HBV X gene significantly activated CtBP2 gene promoter activity, and CtBP2 mRNA and protein expression were upregulated by the HBV X gene. This activation effect was enhanced by the increase in the dose of the X gene, showing metrological dependence. Conclusion HBV may be involved in the occurrence and development of HCC by upregulating CtBP2 expression.

Abstract
Bangladesh introduced hepatitis B vaccine in a phased manner during 2003-2005 into the routine childhood vaccination schedule. This study was designed to evaluate the impact of the introduction of hepatitis B vaccine in Bangladesh by comparing hepatitis B surface antigen (HBsAg) prevalence among children born before and after vaccine introduction and to estimate the risk of vertical transmission of chronic hepatitis B virus (HBV) infection from mother to infant. We also evaluated the field sensitivity and specificity of an HBsAg point-of-care test strip. We selected a nationally representative sample of 2,100 prevaccine era and 2,100 vaccine era children. We collected a 5-mL blood sample from each child. One drop of blood was used to perform rapid HBsAg testing. If a child had a positive HBsAg test result with the rapid test, a blood sample was collected from the mother of the HBsAg-positive child and from the mothers of two subsequently enrolled HBsAg-negative children. All samples were tested for serologic markers of HBV infection using standard enzyme-linked immunosorbent assay. One (0.05%) child in the vaccine era group and 27 (1.2%; 95% confidence interval [CI]: 0.8-1.7%) children in the prevaccine era group were HBsAg positive. Mothers of HBsAg-positive children were more likely to be HBsAg positive than mothers of HBsAg-negative children (odds ratios = 4.7; 95% CI: 1.0-21.7%). Sensitivity of the HBsAg rapid test was 91.2% (95% CI: 76.6-98.1%) and specificity was 100% (95% CI: 99.9-100%).
