Abstract
Background and aims Chronic viral hepatitis B (CHB)-infected patients occasionally develop cirrhosis despite having persistent viral suppression with antiviral therapy. We aimed to identify risk factors for developing cirrhosis in hepatitis B virus (HBV)-suppressed patients. Methods We conducted a case-control study involving 120 noncirrhotic CHB-infected patients achieving viral suppression with antiviral treatment, with 40 cases developing cirrhosis and 80 age-, sex-, and Fibrosis-4 (FIB-4)-matched controls. Clinical and laboratory data at viral suppression, including body mass index (BMI), comorbidities, pretreatment HBV viral load, HBe antigen status, hepatitis C virus (HCV) and HIV coinfections, liver chemistries, and AST to Platelets Ratio Index (APRI) values, were retrospectively abstracted. Risk factors for cirrhosis post-HBV suppression were identified using Cox proportional hazard analysis. Results Case and control groups had similar ages (51.4 ± 9.9 vs. 51.4 ± 10.2 years), proportions of males (80% vs. 80%), and FIB-4 values (1.32 vs. 1.31). The cirrhosis group showed significantly higher BMI (25.1 vs. 22.7, P = 0.01) and more diabetes prevalence (50.0% vs. 26.3%, P = 0.01), while other comorbidities and laboratory parameters were comparable (P > 0.05). By univariate analysis, BMI >23 kg/m2, diabetes, and APRI >0.7 were significantly associated with cirrhosis, with hazard ratios (HRs) (95%CI) of 2.99 (1.46-6.13), 2.31 (1.23-4.36), and 2.71 (1.05-6.99), P = 0.003, 0.010, and 0.039, respectively. In multivariate analyses adjusted for APRI, BMI>23 kg/m2 remained significantly associated with cirrhosis (aHR: 2.76, P = 0.006), while diabetes showed borderline significance (aHR: 1.99, P = 0.072). Conclusions In HBV-infected patients achieving viral suppression with therapy, a BMI >23 kg/m2 increases the risk of cirrhosis. Therefore, a comprehensive approach addressing metabolic factors is imperative for preventing disease progression in HBV-infected patients.

Abstract
BACKGROUND Global elimination of hepatitis B virus (HBV) requires expanded uptake of antiviral therapy, potentially by simplifying testing algorithms, especially in resource-limited countries. We evaluated the effectiveness, cost-effectiveness, and budget impact of three strategies that determine eligibility for anti-HBV treatment, as compared with the WHO 2015 treatment eligibility criteria, in The Gambia. METHODS We developed a microsimulation model of natural history using data from the Prevention of Liver Fibrosis and Cancer in Africa programme (known as PROLIFICA) in The Gambia, for an HBV-infected cohort of individuals aged 20 years. The algorithms included in the model were a conventional strategy using the European Association for the Study of the Liver (EASL) 2017 criteria, a simplified algorithm using hepatitis B e antigen and alanine aminotransferase (the Treatment Eligibility in Africa for the Hepatitis B Virus [TREAT-B] score), a Treat All approach for all HBV-infected individuals, and the WHO 2015 criteria. Outcomes to measure effectiveness were disability-adjusted life years (DALYs) and years of life saved (YLS), which were used to calculate incremental cost-effectiveness ratios (ICERs) with the WHO 2015 criteria as the base-case scenario. Costs were assessed from a modified social perspective. A budget impact analysis was also done. We tested the robustness of results with a range of sensitiviy analyses including probabilistic sensitivity analysis. FINDINGS Compared with the WHO criteria, TREAT-B resulted in 4877 DALYs averted and Treat All resulted in 9352 DALYs averted, whereas the EASL criteria led to an excess of 795 DALYs. TREAT-B was cost-saving, whereas the ICER for Treat All (US$2149 per DALY averted) was higher than the cost-effectiveness threshold for The Gambia (0·5 times the country's gross domestic product per capita: $352). These patterns did not change when YLS was the outcome. In a modelled cohort of 5000 adults (aged 20 years) with chronic HBV infection from The Gambia, the 5-year budget impact was $1·14 million for Treat All, $0·66 million for TREAT-B, $1·03 million for the WHO criteria, and $1·16 million for the EASL criteria. Probabilistic sensitivity analysis indicated that among the Treat All, EASL, and TREAT-B algorithms, Treat All would become the most preferred strategy only with a willingness-to-pay threshold exceeding approximately $72 000 per DALY averted or $110 000 per YLS. INTERPRETATION Although the Treat All strategy might be the most effective, it is unlikely to be cost-effective in The Gambia. A simplified strategy such as TREAT-B might be a cost-saving alternative. FUNDING UK Research and Innovation (Medical Research Council).

Abstract
AIM Given the current literature data, this article aims to shed light on the epidemiological and clinical effects of HBV, as well as its impact on the development of hepatocellular carcinoma (HCC). METHODS A review of the English language literature based on a MEDLINE (PubMed) database was searched. The keywords were cirrhosis, hepatocellular carcinoma, epidemiology, hepatitis delta virus, hepatitis B virus, and co-infection. All references from retrieved papers were reviewed systematically to find additional collection of reports. RESULTS The study has broadly confirmed the contribution of HDV viremia to liver disease and cirrhosis. However, uncertainty over the mechanism of action on HCC development remains. As the recent data has demonstrated, the HCC-HDV has a unique molecular profile which is distinct from that of HBV-HCC. CONCLUSION Owing to the dependence of HDV on HBV, it is not clear whether HCC is a consequence of the cumulative effect of both HBV and HDV, an effect of the underlying cirrhosis, or a direct oncogenic effect of HDV. Many questions concerning the oncogenic role of HDV remain unanswered. To better understand the role of HDV in carcinogenesis, studies at the molecular level that consider genotype differences should be increased. Multicenter, high-volume, and prospective studies that compare HBV/HDV co-infected and HBV-infected individuals will be pivotal in determining the oncogenic role of HDV.

Abstract
OBJECTIVES Hepatitis B virus infection is an important public health problem. We analysed the cost-effectiveness of the first-line therapies, including nucleotide analogues (namely tenofovir alafenamide fumarate (TAF), tenofovir disoproxil fumarate (TDF) and entecavir) and pegylated interferon (Peg-IFN) for patients with chronic hepatitis B (CHB) in China. METHODS A Markov model describing CHB disease progression was constructed to compare the cost-effectiveness of the first-line therapies, considering both satisfactory (HBeAg seroconversion) and optimal (HBsAg seroclearance) treatment goals. We examined the main outcomes, including cumulative lifetime cost per patient, incremental quality-adjusted life years (QALYs), incremental cost-effectiveness ratio and net monetary benefit. Uncertainty analysis was conducted to identify key influential parameters. RESULTS Compared with the baseline strategy, Peg-IFN had the highest QALY gain for HBeAg-positive (HBeAg+) CHB patients achieving a satisfactory goal and an optimal goal (3.19 and 6.32 respectively), and TDF was the most cost-effective therapy for HBeAg-negative CHB patients ($1418/QALY) achieving a satisfactory goal. Among nucleotide analogues, TAF was the most-effective strategy and had higher acceptability to achieve an optimal goal in the Eastern region of China (under 1 x GDP per capita threshold). CONCLUSIONS Among nucleotide analogues, TDF was the most cost-effective treatment in China for CHB patients to achieve satisfactory and optimal treatment goals, whereas TAF was cost-effective and more effective in the wealthier region. Peg-IFN was most cost-effective among HBeAg+ CHB patients to achieve both goals, with better clinical outcomes. Our findings also indicate the importance of regular monitoring during and after CHB treatment, and could inform treatment strategies in China and other countries.

Abstract
PURPOSE To clarify and investigate the prevalence and clinical impact of hepatitis D virus (HDV) infection in Taiwan's communities. METHODS HDV infection in patients with chronic hepatitis B viral (HBV) infection was examined using an anti-HDV antibody in Yonghe Cardinal Tien Hospital (YCTH), a district hospital in Taiwan. Clinical characteristics of anti-HDV-positive and anti-HDV-negative patients were collected and compared. These characteristics were also compared with the data collected from a medical center. Continuous variables and confounding factor adjustments were compared using the analysis of covariance method, whereas categorical variables were compared using the logistic regression method. RESULTS A total of 346 patients with chronic HBV infection were assessed from 2018 to 2019. Among them, 4 (1.15%) were positive for anti-HDV. The clinical, virological, and biochemical characteristics were similar between anti-HDV-positive and anti-HDV-negative groups. None of the four patients was positive for serum HDV RNA. Another 18 anti-HDV-positive patients were identified from National Taiwan University Hospital (NTUH). The clinical, virological, and biochemical characteristics of anti-HDV-positive patients from YCTH and NTUH were also similar. CONCLUSION The prevalence of HDV and the serum HDV RNA-positive rate were low in district hospitals in Taiwan. Coexisting HDV infection did not influence the clinical manifestation of patients with chronic HBV infection in Taiwan. However, because the number of HDV RNA cases was very small, our findings may not be conclusive. Besides, since the sensitivity of current anti-HDV kit is not 100%, more sensitive methods are needed to achieve reliable prevalence data.

Abstract
OBJECTIVES In longitudinal studies, serum biomarkers are often measured longitudinally which is valuable to predict the risk of disease progression. Previous risk prediction models for liver cirrhosis restrict data to baseline or baseline and a single follow-up time point, which failed to incorporate the time-dependent marker information. The aim of this study is to develop risk model in patients with chronic hepatitis B for dynamic prediction of cirrhosis by incorporating longitudinal clinical data. METHODS Data from the hospital-based retrospective cohort at the Third Affiliated Hospital of Sun Yat-sen University, from 2004 to 2016, were analyzed. Using the multilevel logistic regression model, the time-dependent marker information and individual characteristics were taken as input, and the risk of at different time as the output. RESULTS At the end of follow-up, 8.8% of patients progressed to cirrhosis, the average estimate values of hepatitis B virus DNA and alanine aminotransferase demonstrated a downward trend, the aspartate aminotransferase/alanine aminotransferase ratio showed a flat trend overall. The important predictors were as follows: age, oral antiviral treatment, hepatitis B virus DNA. This risk prediction model had an area under the receiver operator characteristic curve of 0.835 (95% confidence interval: 0.772-0.899) and 0.809 (95% confidence interval: 0.708-0.910) in the derivation and validation sets, respectively. CONCLUSION Longitudinal prediction model can be used for dynamic prediction of disease progression and identify changing high-risk patients.

Abstract
Background The objective of our research was to assess the possible link between diabetes mellitus (DM) and liver cirrhosis in chronic hepatitis B (CHB) patients in Wuhan, China. Material/Methods Individuals with a diagnosis of both liver cirrhosis and chronic HBV infection (n=257), and CHB-only patients (n=514) were matched 1: 2 by age and sex. Demographic, lifestyle, laboratory, and clinical characteristics were reviewed. Univariate and the multiple logistic regression analysis were conducted to investigate the association between DM and HBV-related liver cirrhosis. Results The prevalence of DM was higher among CHB patients with liver cirrhosis than in those without liver cirrhosis (22.2% vs. 12.8%, P=0.001), yielding an adjusted odds ratio (AOR) of 2.317 and a 95% confidence interval (CI) of 1.528–3.513. Among them, 87.7% of liver cirrhosis patients were diagnosed with DM before liver cirrhosis diagnosis, yielding an AOR (95% CI) of 2.386 (1.533–3.714). In comparison to patients with a DM duration of 2–5 years, the AOR (95% CI) for those with a DM duration >5 years was 2.073 (0.701–6.132). In DM treatment, the AOR (95% CI) for those treated with insulin was 4.746 (1.329–16.949). Conclusions DM was associated with cirrhosis risk in CHB patients in Wuhan, China.

Abstract
Advances in the diagnosis, monitoring, and treatment of hepatitis B virus (HBV) infection are urgently required if we are to meet international targets for elimination by the year 2030. Here we demonstrate how routine clinical data can be harnessed through an unbiased electronic pipeline, showcasing the significant potential for amassing large clinical data sets that can help to inform advances in patient care and provide insights that may help to inform new cure strategies. Our cohort from a large UK hospital includes adults from diverse ethnic groups that have previously been underrepresented in the literature. By tracking two protein biomarkers that are used to monitor chronic HBV infection, we provide new insights into the timelines of HBV clearance, both on and off treatment. These results contribute to improvements in individualized clinical care and may provide important clues into the immune events that underpin disease control. HBsAg and HBeAg have gained traction as biomarkers of control and clearance during chronic hepatitis B virus infection (CHB). Improved understanding of the clearance correlates of these proteins could help inform improvements in patient-stratified care and advance insights into the underlying mechanisms of disease control, thus underpinning new cure strategies. We collected electronic clinical data via an electronic pipeline supported by the National Institute for Health Research Health Informatics Collaborative (NIHR HIC), adopting an unbiased approach to the generation of a robust longitudinal data set for adults testing HBsAg positive from a large UK teaching hospital over a 6-year period (2011 to 2016 inclusive). Of 553 individuals with CHB, longitudinal data were available for 319, representing >107,000 weeks of clinical follow-up. Among these 319 individuals, 13 (4%) cleared HBsAg completely. Among these 13, the HBsAg clearance rate in individuals on nucleos(t)ide analogue (NA) therapy (n = 4 [31%]; median clearance time,150 weeks) was similar to that in individuals not on NA therapy (n = 9 [69%]; median clearance time, 157 weeks). Those who cleared HBsAg were significantly older and less likely to be on NA therapy than nonclearers (P = 0.003 and P = 0.001, respectively). Chinese ethnicity was associated with HBeAg positivity (P = 0.025). HBeAg clearance occurred in individuals both on NA therapy (n = 24; median time, 49 weeks) and off NA therapy (n = 19; median time, 52 weeks). Improved insights into the dynamics of these biomarkers can underpin better prognostication and patient-stratified care. Our systematized approach to data collection paves the way for scaling up efforts to harness clinical data to address research questions and support improvements in clinical care.

Abstract
Hepatitis delta virus (HDV) is a small defective virus that needs hepatitis B virus (HBV) to replicate and propagate. HDV infection affects 20-40 million people worldwide and pegylated interferon (PegIFN) is the only recommended therapy. There is limited data on the contribution of HDV infection to HBV-related liver disease or liver cancer. Evidence from retrospective and cohort studies suggests that HBV/HDV coinfection accelerates progression to cirrhosis and is associated with an increased risk of hepatocellular carcinoma (HCC) development compared to HBV monoinfection. Although the life cycle of HDV is relatively well known, there is only ancillary information on the molecular mechanisms that can drive specific HDV-related oncogenesis. No thorough reports on the specific landscape of mutations or molecular classes of HDV-related HCC have been published. This information could be critical to better understand the uniqueness, if any, of HDV-related HCC and help identify novel targetable mutations. Herein, we review the evidence supporting an oncogenic role of HDV, the main reported mechanisms of HDV involvement and their impact on HCC development.

Abstract
Objective: This study aims to clarify the changes and clinical significance of red cell distribution width (RDW) during HBV-related chronic diseases, including inactive hepatitis B virus (HBV) carriers, HBV immune tolerant individuals, chronic hepatitis B (CHB) patients and HBV-related hepatocirrhosis patients. Methods: RDW was measured 288 CHB patients, 100 patients with hepatitis B e antigen(HBeAg)-negative chronic HBV infection (inactive carriers), 92 patients with HBeAg-positive chronic HBV infection (immune tolerant), and 272 patients with HBV-related hepatocirrhosis. Their RDW changes were compared with 160 healthy controls. Correlations between RDW and clinical indicators were conducted. For HBeAg+ CHB patients, RDW was measured before and after antiviral therapy. The efficiency of RDW to distinguish hepatocirrhosis from CHB and/or inactive carriers was evaluated by receiver operating characteristic (ROC) curves. Results: RDW was higher in hepatocirrhosis patients than other groups of patients and healthy controls. Besides, HBeAg+ CHB patients possessed higher RDW than HBeAg- CHB patients. For HBeAg+ patients that underwent HBeAg seroconversion after antiviral therapy, RDW was decreased. RDW was positively correlated with total bilirubin and Child-Pugh scores and negatively correlated with albumin among hepatocirrhosis patients. The areas under the curve (AUC) of ROC curves to distinguish hepatocirrhosis from CHB patients was 0.7040 for RDW-standard deviation (RDW-SD) and 0.6650 for RDW-coefficient of variation (RDW-CV), and AUC to distinguish hepatocirrhosis from inactive carriers was 0.7805 for RDW-SD and 0.7991 for RDW-CV. Conclusions: RDW is significantly increased in HBeAg+ CHB patients and patients with HBV-related hepatocirrhosis and could reflect their severity. RDW could help to distinguish hepatocirrhosis from CHB patients and inactive HBV carriers.

Abstract
OBJECTIVE Among individuals with chronic hepatitis B, those with hepatitis B e-antigen (HBeAg)-negative chronic hepatitis (CHB) can be difficult to distinguish from those with HBeAg-negative chronic HBV infection, also referred to as inactive HBV carriers (ICs), but both require different medical management. The level of HBV surface antigen (HBsAg) has been proposed as a marker to discriminate between chronic infection and hepatitis stages. HBsAg consists of large, middle and small HBs. The aim of this study was to determine whether the composition of HBsAg improved the identification of ICs among HBsAg-positive subjects with different phases of HBV infections. DESIGN HBV large surface proteins (LHBs) and HBV middle surface proteins (MHBs) were quantified in serum samples from 183 clinically well-characterised untreated patients with acute (n=14) HBV infection, ICs (n=44), CHBs (n=46), chronic HBeAg-positive phase (n=68) and hepatitis delta coinfection (n=11) using an ELISA, with well-defined monoclonal antibodies against the preS1 domain (LHBs) and the preS2-domain (MHBs). A Western blot analysis was used to verify the quantitation of the components of HBsAg. Total HBsAg was quantified using a modified commercially available assay (HBsAg V.6.0, Enzygnost, Siemens, Erlangen). RESULTS The composition of HBsAg showed specific patterns across different phases of hepatitis B. Individuals in the IC phase had significantly lower proportions of LHBs and MHBs than patients in acute or chronic phases irrespective of their HBV e-antigen status (p<0.0001) or HBsAg level. Both LHBs and MHBs ratios better predicted the IC phase than total HBsAg levels. CONCLUSION Quantification of MHBs, particularly LHBs represents a novel tool for the identification of the IC stage.

Abstract
Tenofovir alafenamide (TAF), a novel prodrug of tenofovir was developed to deliver enhanced antiviral potency and reduced systemic toxicities by more efficient intracellular delivery of the active metabolite tenofovir disphosphate than tenofovir disoproxil fumarate (TDF). In two randomized, double-blind, multinational phase III trials in patients with hepatitis B e antigen (HBeAg)-positive or -negative infection, TAF 25 mg was non-inferior to TDF 300 mg in achieving the primary efficacy outcome of a hepatitis B virus (HBV) DNA level < 29 IU/ml at week 48 and was associated with higher rates of alanine aminotransferase (ALT) normalization based on AASLD (American Association for the Study of Liver Diseases) criteria. TAF was well tolerated with low rates of adverse events, comparable to TDF. A significantly lower decline in the estimated glomerular filtration rate (eGFR) was observed in patients receiving TAF compared with patients receiving TDF and loss of bone mineral density at the hip and spine was significantly lower in the TAF groups. These trends continued to week 96. The requirement for long-term therapy in chronic HBV highlights the importance of these efficacy and safety trends, however their true clinical relevance is yet to be established and further studies with long-term follow up and real-world clinical data are needed.

Abstract
OBJECTIVE To explore the long-term prognosis and health-related quality of life of patients surviving hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF). METHODS The clinical data were collected from patients with HBV-ACLF, who were hospitalized in our department between November, 2011 and October, 2016 and survived for more than 90 days. The patients were followed for occurrence of newly diagnosed cirrhosis, decompensation events, hepatocellular carcinoma and death. The quality of life of the patients was evaluated using SF-36 score, and the patients with chronic hepatitis B (CHB) and cirrhosis treated during the same period served as controls. RESULTS A total of 223 ACLF survivors were included in this study. According to the presence of cirrhosis on admission, the enrolled patients were divided into chronic hepatitis B-related ACLF (CHB-ACLF) group (n=130) and liver cirrhosis ACLF (CIR-ACLF) group (n=93). The 12-, 24- and 50-month survival rates in CHB-ACLF group were 97%, 95.7% and 93.9%, respectively, significantly higher than the rates in CIR-ACLF group (91%, 86% and 74%, respectively; P=0.007). In patients with CHB-ACLF, the 12-, 24- and 36-month progression rates of cirrhosis were 37.9%, 58.4% and 68.7% respectively. Multivariate Cox regression identified the peak value of serum creatinine (HR=1.015, P=0.026) and INR (HR=2.032, P=0.006) within 28 days as independent risk factors and serum sodium at baseline (HR=0.84, P=0.035) as an independent protective factor of occurrence of cirrhosis. The score of mental health on SF-36 in ACLF group was significantly lower than the national norms, and the scores for general health and body pain of ACLF patients were significantly higher than those in patients with CHB or cirrhosis. CONCLUSION The long-term prognosis of ACLF survivors with and without cirrhosis can be different. Acute attacks are associated with an increased rate of cirrhosis progression in CHB patients who recovered from ACLF, possibly in relation with the severity of extra-hepatic organ injuries. The physical and social functions of long-term survivors of ACLF do not significantly decline, but their psychological status can be affected.

Abstract
Transjugular intrahepatic portosystemic shunting (TIPS) is an effective treatment modality for refractory variceal bleeding and ascites in patients with cirrhotic portal hypertension (CPH). Variceal rebleeding and shunt dysfunction are major post-TIPS morbidities. This study aimed to retrospectively evaluate the effectiveness and safety of use of concomitant variceal embolization and prophylactic antiplatelet/anticoagulative in patients with CPH undergoing TIPS. Between October 2006 and October 2011, 182 patients with CPH were retrospectively and consecutively hospitalized for elective TIPS with Fluency stenting. Concomitant variceal embolization was given after establishing the shunt. Subcutaneous heparin was given after TIPS and replaced by oral clopidogrel, aspirin, or warfarin for at least 6 months. Main outcome measures included shunt patency rate, recurrence of CPH (rebleeding and/or refractory ascites), hepatic encephalopathy (HE) frequency, and post-TIPS survival. The cumulative primary patency rate was 96%, 94%, 90%, 88%, and 88% at 6, 12, 24, 36, and 48 months, respectively. Shunt stenosis occurred in 16 (9%) patients, gastrointestinal (GI) rebleeding in 32 (17.5%) patients, recurrence of refractory ascites 44 (48%) patients, HE in 42 (23%) patients, and death in 36 (20%) patients during the follow-up period. Use of concomitant variceal embolization and prophylactic antiplatelet/anticoagulative was associated with a favorable shunt patency and a low risk of GI rebleeding.

Abstract
Objective To determine whether genetic polymorphisms in the uridine diphosphate-glucuronosyltransferase 1A (UGT1A) and the C-C motif chemokine receptor 5 (CCR5) genes are associated with hepatitis B virus (HBV) infection in Yi, Yao and Han ethnic groups in the Guizhou Province of China. Methods The study enrolled subjects with and without HBV infection. Whole blood was used for DNA genotyping using standard techniques. The study determined the frequencies of several polymorphic alleles (UGT1A6 [rs2070959], UGT1A1 [rs8175347], CCR5-59029 [rs1799987] and CCR5Δ32 [rs333]) and then characterized their relationship with HBV infection. Results A total of 404 subjects were enrolled in the study: 138 from the Yao group, 101 from the Yi group and 165 from the Han group. There was a significant difference in the frequency of UGT1A1 rs8175347 polymorphisms among the three groups. The rates of 7TA carriers of UGT1A1 rs8175347 in all three groups were significantly higher than the other genotypes. Individuals with genotype AA of UGT1A6 rs2070959 in the Yi group had a higher risk for HBV infection than in the Yao and Han groups. The frequency of genotype GG in CCR5-59029 in the Yao group was significantly higher than in the Yi group. The genotypes of CCR5Δ32 were not associated with HBV infection. Conclusion These findings provide genetic and epidemiological evidence for an association of UGT1A and CCR5-59029 polymorphisms with HBV infection in Chinese Yi and Yao populations.

Abstract
With rapidly aging population in the world, many elderly patients present with hepatitis B virus (HBV) infection. We conducted a retrospective cohort study involving 359 untreated HBV patients aged 60 and older who were free of hepatocellular carcinoma (HCC) and acute hepatitis at the initial visit, and examined the incidence of HCC and liver-related mortality rate. During the follow-up period of 7.9 years (range, 0-25 years), 26 patients (7.2% of patients) developed HCC, 20 patients died from liver-related diseases (61% of total deaths), including HCC, liver failure, and gastrointestinal bleeding. The cumulative rates of HCC at years 5, 10, and 15 were 6.5%, 15.6%, and 15.6%, respectively. The cumulative rates of mortality from liver-related diseases at years 5, 10, 15 were 3.3%, 12.3%, and 15.7%, respectively. Multivariate analysis identified HBV DNA (≥5.0 Log IU/mL), male gender, and FIB4-Index (≥3.6) as significant independent risk factors for HCC, and alpha-fetoprotein (≥10 ng/mL) as significant independent predictors of liver-related mortality. We conclude that high levels of HBV DNA, progression of liver fibrosis, and male gender are independent risk factors of HCC in untreated patients infected with HBV aged 60 and older.

Abstract
Despite the burden of diabetes mellitus (DM), little is known about the role of this and other metabolic syndromes on the severity of hepatitis B virus (HBV) chronicity and liver disease progression. The value of hepatitis B vaccination and its impact on liver diseases and HCC has been largely demonstrated, adult vaccination coverage is however suboptimal and DM diagnosis represents an opportunity for the HCP to discuss hepatitis B and other adult vaccinations. We performed a systematic literature search to identify studies (January 2000 to January 2017) describing liver disease progression among patients with HBV by DM status. Risk factors were assessed including the relationship between HBV and non-alcoholic steatohepatitis (NASH). Data were extracted systematically and assessed descriptively. Twenty articles described liver disease progression and one article evaluated NASH among subjects with HBV by DM status. Fourteen articles reported that DM as a predictor for the outcome, including delayed seroclearance, cirrhosis, hepatocellular carcinoma, transplant/mortality and death, whereas no association on liver outcomes was found in 7 studies. In summary, our review suggests that DM is associated with the progression of severe liver outcomes in adults with HBV, although more studies are needed to understand the benefits of HBV vaccination in adults with DM and liver-diseases.

Abstract
Aim To characterize the effect of hepatic steatosis (HS) on the progression of chronic hepatitis B. Methods A total of 162 chronic hepatitis B (CHB) patients confirmed by liver biopsy were involved in this study. All subjects were prospectively followed-up for 5 years in real-life clinical practice. Fibrosis stage was determined using aspartate aminotransferase-to-platelet ratio index (APRI). The end-point was cirrhosis, liver cancer or death. The effects of steatosis on the biological behavior of hepatocellular carcinoma cells were investigated using oleic acid-induced lipid accumulation in HepG2, HLE, PLC, and SMMC-7721 cells. Results Mean age, body mass index, and serum cholesterol were significantly higher in CHB patients with HS than those without HS at baseline (p< 0.05). The APRI was lower in patients without HS at baseline (p<0.05). Compared to patients with HS, APRI of patients without HS decreased significantly during the follow-up period (p<0.05). The 5-year cumulative incidence of cirrhosis were 4.17% and 5.19% in patients without and with HS, respectively (p>0.05). The multivariate analysis showed that older (RR 1.07, 95% CI 0.996-1.149, p = 0.065) and S3 stage of liver fibrosis (RR 3.50, 95% CI 0.812–15.117, p=0.093) were risk factors for the progression to cirrhosis. In vitro, cell steatosis promoted proliferation and migration of HCC cells and conferred cell cycle at S phase. Conclusion The older and S3 stage of fibrosis may be risk factors for progression to cirrhosis in CHB patients with HS. HS may aggravate liver disease, promoting HCC progression.

Abstract
OBJECTIVE To describe the epidemiological, analytical and histological characteristics and clinical course of hepatitis B virus (HBV) carriers with negative HBe antigen. MATERIAL AND METHODS Observational, retrospective cohort study of HBV carriers with negative HBe antigen (2005-2012), with no other causes of liver disease. RESULTS One hundred and thirty-eight patients were included, with mean age 40.5±12.2 years; 54% were women, and 38% were of foreign origin; the number of foreign patients significantly increased (P<.001) over the years. Transaminases were normal in nearly 75% and HBV-DNA was <2,000IU/ml in 56% of patients at diagnosis. There was a gradual decrease in HBV-DNA levels in inactive carriers over the study period. Fibrosis study was performed in 47% of patients by Fibroscan® or liver biopsy: 55.4% normal histology and 6.1% cirrhosis. Just over three quarters of patients (77.77%) were inactive carriers. Treatment was required in 15.5% of patients (20% because of cirrhosis and 80% HBeAg-negative chronic hepatitis B). Five patients cleared HBsAg (annual rate .94%), all of whom presented HBV-DNA <2,000IU/ml at diagnosis. Five patients developed complications (3.6%), 4 of them hepatocellular carcinoma (HCC), of which only 2 had cirrhosis. There was 1 HBV-related death (.72%). CONCLUSION Among HBV carriers with negative HBe antigen, inactive HBs-Ag carriers are predominant. HBV-DNA gradually decreases in the first few years after diagnosis. Morbidity and mortality are low, especially if glutamic pyruvic transaminase (GPT) is normal and HBV-DNA levels are low at diagnosis. Treatment is needed in a considerable number of patients. HCC is the most frequent complication, even in the absence of cirrhosis.

Abstract
BACKGROUND Despite the high burden of hepatitis B virus (HBV) infection in sub-Saharan Africa, absence of widespread screening and poor access to treatment leads to most people remaining undiagnosed until later stages of disease when prognosis is poor and treatment options are limited. We examined the cost-effectiveness of community-based screening and early treatment with antiviral therapy for HBV in The Gambia. METHODS In this economic evaluation, we combined a decision tree with a Markov state transition model to compare a screen and treat intervention consisting of adult community-based screening using a hepatitis B surface antigen (HBsAg) rapid test and subsequent HBV antiviral therapy versus current practice, in which there is an absence of publicly provided screening or treatment for HBV. We used data from the PROLIFICA study to parameterise epidemiological, primary screening, and cost information, and other model parameter inputs were obtained from a literature search. Outcome measures were cost per disability-adjusted life-year (DALY) averted; cost per life-year saved; and cost per quality-adjusted life-year (QALY) gained. We calculated the incremental cost-effectiveness ratios (ICERs) between current practice and the screen and treat intervention. Costs were assessed from a health provider perspective. Costs (expressed in 2013 US$) and health outcomes were discounted at 3% per year. FINDINGS In The Gambia, where the prevalence of HBsAg is 8·8% in people older than 30 years, adult screening and treatment for HBV has an incremental cost-effectiveness ratio (ICER) of $540 per DALY averted, $645 per life-year saved, and $511 per QALY gained, compared with current practice. These ICERs are in line with willingness-to-pay levels of one times the country's gross domestic product per capita ($487) per DALY averted, and remain robust over a wide range of epidemiological and cost parameter inputs. INTERPRETATION Adult community-based screening and treatment for HBV in The Gambia is likely to be a cost-effective intervention. Higher cost-effectiveness might be achievable with targeted facility-based screening, price reductions of drugs and diagnostics, and integration of HBV screening with other public health interventions.

Abstract
BACKGROUND AND OBJECTIVES Development of cirrhosis and hepatocellular carcinoma (HCC) are critical milestones in the natural history of chronic hepatitis B virus (HBV) infection. There are no prospective data on the risk of these critical milestones in HBV patients in Singapore. The efficacy and justification of HCC surveillance is determined by the rate of HCC development. Our study aims to determine the rates of cirrhosis and HCC in HBV patients in Singapore and hence the appropriateness of HCC surveillance. MATERIALS AND METHODS A total of 673 HBV patients were enrolled between March 2003 and March 2004 and followed up for 10 years with regular surveillance for HCC using α-fetoprotein and abdominal ultrasound. RESULTS Overall, 62.6% of the patients were men, mean age 56.4 years. In all, 31% were hepatitis B e antigen-positive and 14.9% had cirrhosis at baseline. Seventy-four patients developed cirrhosis and 42 patients developed HCC after 10 years. The overall 10-year incidence of cirrhosis and HCC was 16.2% (1.6%/year) and 7.8% (0.8%/year), respectively. The overall incidence of HCC in cirrhotics was 29.7% (3.0%/year), highest within a year of diagnosis of cirrhosis (7.9%). The rate of cirrhosis was significantly higher in those aged more than 55 years (P=0.001). Sex and hepatitis B e antigen status did not affect the rate of cirrhosis. Factors with significantly higher overall rates of HCC were age 55 years or more (P=0.001), male sex (P=0.001), and baseline α-fetoprotein of 4.1 µg/l or more (P<0.0001). However, age more than 55 years was not significant in the development of HCC in cirrhotics. CONCLUSION The rate of cirrhosis in HBV patients in Singapore is about 1.6% per year. The rate of HCC is about 0.8% per year overall and 3.0% per year in cirrhotics, which justifies HCC surveillance.

Abstract
Chronic liver diseases, such as chronic hepatitis B (CHB) and chronic hepatitis C (CHC), are characterized by the presence of liver fibrosis, which may ultimately lead to cirrhosis. The progression of fibrosis is associated with various factors. Here, we review recent advances in the study of factors related to the progression rate of CHB- and CHC-induced fibrosis. Identification of these factors and establishment of a scoring system for cirrhosis risk are particularly important for predicting cirrhosis development, planning individualized treatment, and preventing fibrosis progression.

Abstract
OBJECTIVES In the era of antiviral therapy, the prognostic significance of serum hepatitis B virus (HBV) DNA level as a biological gradient substantially diminished, as most patients can achieve complete virological response (CVR). We aimed to investigate the predictive roles of liver stiffness (LS) for liver-related events (LREs) among patients with CVR. METHODS We analyzed 192 patients with chronic HBV infection who achieved CVR (defined as HBV DNA <20 IU/ml) through entecavir therapy. LS values at CVR were measured using transient elastography. LREs were defined as any cirrhotic complication, hepatocellular carcinoma, and liver-related mortality. RESULTS The median age of the patients was 49 years, and 134 (69.8%) were male. The median LS value at CVR was 8.8 kPa. During follow-up, LREs occurred in 25 (13.0%) patients. When the population was stratified into three groups (<8.0 kPa, 8.0-13.0 kPa, and >13.0 kPa), cumulative LRE incidences increased significantly in association with LS values (log-rank test, P=0.001). Patients with an LS value >13.0 kPa (hazard ratio (HR)=12.336, 95% confidence interval (CI) 1.335-114.010; P=0.027) and 8.0-13.0 kPa (HR=8.832, 95% CI 1.092-71.432; P=0.041) were at significantly greater risk compared with those with an LS value <8.0 kPa. On multivariate analysis, age and LS values were seen to be independent predictors (all P<0.05). When LS values were incorporated into the REACH-B scoring model instead of serum HBV DNA level, a better predictive performance was seen compared with a conventional approach (areas under the receiver operating characteristic curve, 0.814 vs. 0.629, respectively). CONCLUSIONS LS values at CVR are useful for predicting forthcoming LRE development. Thus, in the era of potent antiviral therapy, tailored surveillance strategies might be established based upon LS values at CVR.

Abstract
BACKGROUND AND AIMS Chronic hepatitis B (CHB) can progress to cirrhosis, hepatocellular carcinoma (HCC), and ultimately liver-related deaths. Recently, owing to potent antiviral therapy with minimal side-effects, sustained suppression of hepatitis B virus replication can be achieved, thereby preventing such complications. We aimed to reappraise clinical courses regarding disease progression in the era of antiviral therapy. METHODS Between 2001 and 2005, treatment-naïve Korean CHB patients without cirrhosis were enrolled and followed up for at least 5 years. During follow up, antiviral therapy was commenced according to Korean Association for the Study of the Liver guidelines, if eligible, and ultrasonography and laboratory and clinical assessment were performed regularly. Primary end-points were development of cirrhosis, hepatic decompensation, HCC, or liver-related deaths. RESULTS Of 360 patients, 323 (89.7%) received antiviral therapy such as lamivudine (70.6%), entecavir (8.7%), or telbivudine (6.5%). During follow up, cirrhosis developed in 29 (8.1%), hepatic decompensation in 4 (1.1%), and HCC in 15 (4.2%) patients. Annual incidences of cirrhosis, hepatic decompensation, and HCC were 1.05%, 0.14%, and 0.53% per person-year, respectively. Age was an independent predictor for developing cirrhosis (hazard ratio [HR] 1.075, 95% confidence interval [CI] 1.037-1.116; P < 0.001), whereas age (HR 1.060, 95% CI 1.012-1.111; P = 0.014) and cirrhosis (HR 17.470, 95% CI 5.081-60.063; P < 0.001) were those for developing HCC. CONCLUSIONS In the era of antiviral therapy, overall clinical courses have been much improved since introduction of lamivudine in 1999. However, patients with older age or cirrhosis are still subject to HCC development despite appropriate antiviral therapy, necessitating cautious surveillance.

Abstract
Long-lasting HBV-DNA suppression is considered to be the best surrogate end-point of antiviral therapy in patients with hepatitis B virus (HBV) related chronic hepatitis or cirrhosis, and it is a prerequisite to prevent liver-related complications and improve survival. Treatment with oral antiviral drugs in patients with HBV cirrhosis is effective in restoring liver function and improving survival even in those with decompensated cirrhosis. These agents are generally well-tolerated for long-term treatment, and several evidences have demonstrated that they are able to reverse liver fibrosis and prevent the occurrence of HCC.

Abstract
BACKGROUND The impact of diabetes on cirrhosis, its decompensation, and their time relationship in patients with chronic hepatitis B (CHB) remain unclear. METHODS We conducted a nationwide cohort study by using the Taiwanese National Health Insurance Research Database, which was comprised of data from >99% of the entire population. Among 1 million randomly sampled enrollees, 14 523 adult CHB patients were identified from 1997 to 2009. Diabetes was defined as newly diagnosed in CHB patients who were given the diagnosis in the years 1998-2001 but not in 1996-1997 and with physician visits of at least twice per year. The cohorts of CHB with newly diagnosed diabetes (n = 351) and without diabetes (n = 7886) were followed up from the diagnosis of diabetes and from 2000 in the patients without diabetes until development of cirrhosis or its decompensation, withdrawal from insurance, or December 2009. RESULTS Kaplan-Meier survival analysis showed a significantly higher cumulative incidence of cirrhosis (relative risk [RR] = 3.43; 95% confidence interval [CI], 2.62-4.49; P < .001, log-rank test) and decompensated cirrhosis (RR = 4.11; 95% CI, 2.95-5.70; P < .001, log-rank test) among patients with newly developed diabetes compared with those without diabetes. After adjustment for age, sex, CHB treatment, hepatocellular carcinoma, and comorbidity index by Cox proportional hazards model, diabetes was still an independent predictor for cirrhosis (hazard ratio [HR] = 2.015; 95% CI, 1.393-2.915; P < .001) and its decompensation (HR = 1.792; 95% CI, 1.192-2.695; P = .005). CONCLUSIONS Patients with CHB who develop diabetes are at an increased risk of liver cirrhosis and its decompensation over time.

Abstract
BACKGROUND Hepatitis B virus (HBV) is one of the most common chronic viral infections in the world. Iran has a low to intermediate HBV prevalence and approximately 1.5 million people are living with HBV infection. The impact of HBV in Iran is unknown and given the very low levels of alcohol consumption, this region provides an opportunity to examine the impact of isolated chronic HBV infection. OBJECTIVES To examine and evaluate outcome and prognosis of HBV in Iran. PATIENTS AND METHODS A longitudinal cohort study dating from 2003-2010 was performed. The patients were assessed six months after their first visit and then during periodic visits for the subsequent seven years. The patients' medical history, route of diagnosis of infection, family history, and liver diseases status including: carrier state of HBV, chronic HBV, cirrhosis, and HCC were recorded. Descriptive and analytic statistics were performed, using SPSS software version 18. RESULTS 275 HBsAg positive patients, who had completed a 7 year follow up period, were selected. The annual incidence rate for chronic hepatitis B in inactive carrier states and cirrhosis were 0.46% and 0.2% respectively. Over seven years, the rate of inactive carriers decreased by eight percent (They turned into chronic HBV or became HBSAg negative). No significant association was found between HBSAg seroclearance, HBeAg seroconversion and the outcome in the end of each year of follow up. Different treatment regimens did not have any statistically significant difference regarding HBeAg seroconversion. There was no significant association between the outcome and different habitual characteristics, especially smoking, as well as family history on HBsAg, HBsAb, HBeAg, and Anti-HBeAg. Values of platelets and ALT showed a significant change during the follow ups. Annual incidence rate of HCC in the present study was in the range of other studies. CONCLUSIONS These data confirm and extend data from other populations showing a low incidence of significant change in chronic HBV infection in short term with good responses to currently available therapeutics.

Abstract
Host genetics play a vital role in determining clinical outcomes of hepatitis B virus (HBV) infection. To identify novel susceptibility loci to HBV progression, we carried out a genome-wide association study with DNA pooling. This study assessed the relationship between 8 highly-ranked SNPs selected from our DNA pool and disease progression of HBV infection in two independent case-control studies. The first population included 628 asymptomatic HBV carriers (AsC) and 1729 progressed HBV carriers recruited from Hubei Province in south China. The second population was composed of 226 AsC and 215 progressed HBV carriers recruited from Shandong Province in north China. Of the 8 SNPs, variant rs11866328 (G/T), located in the glutamate receptor ionotropic N-methyl D-aspartate 2A (GRIN2A) gene, was replicated and had significant associations with disease progression of HBV infection in the DNA pooling stage both in the Hubei (OR 1.65; 95% CI 1.34,2.02; p=1.96 × 10(-6); additive model), and in the Shandong (OR 1.73; 95% CI 1.14,2.65; p=1.00×10(-2); additive model) population. Polymorphism rs11866328 in the GRIN2A gene might be a genetic variant underlying the susceptibility of HBV carriers to disease progression.

Abstract
Host genetic, environmental and viral factors are classified as three categories that determine clinical outcomes of hepatitis B virus (HBV) infection. The objective of this study was to detect the associations between polymorphisms rs346473 and rs346482 in Rho GTPase-activating protein 24 (ARHGAP24) gene and disease progression of HBV infection in Han Chinese population. These two SNPs were found by our DNA pooling using Affymetrix Genome-Wide Human Mapping SNP6.0 Array in HBV carriers, and verified by using TaqMan 7900HT Sequence Detection System with 758 progressed HBV carriers versus 300 asymptomatic HBV carriers (AsC) in a discovery phase and 971 progressed HBV carriers versus 328 AsC in a replication phase. Multivariable logistic regression revealed that individuals with genotype TT at variant rs346473 displayed remarkable correlations with disease progression of HBV infection both in the discovery phase (OR, 2.693; 95% CI, 1.928-3.760; P=6.2×10(-9); additive model) and the replication phase (OR, 1.490; 95% CI, 1.104-2.012; P=9.0×10(-3); additive model). These two SNPs were in strong linkage disequilibrium with D'=0.99 and r (2)=0.951, and haplotype TT disclosed an increased susceptibility to HBV progression (OR, 1.980; 95% CI, 1.538-2.545; P=8.1×10(-8)). These findings suggest that polymorphism rs346473 in the ARHGAP24 gene might be a part of the genetic variants underlying the susceptibility of HBV carriers to disease progression.

Abstract
Background/Aims Whether alcohol intake increases the risk of hepatocellular carcinoma (HCC) in patients with chronic hepatitis B virus (HBV) infection remains controversial. The aim of this study was to determine the effect of alcohol intake on the development of HCC. Methods Between January 2006 and August 2008, 146 patients with an initial diagnosis of HCC who were hospitalized in 3 major hospitals in the Incheon area were enrolled as cases. Another 146 cirrhotic patients, who matched the cases by age and sex, were enrolled as controls. All cases and controls were HBsAg positive, and had a history of lifetime alcohol intake. Results The cases and controls were aged 53±8 and 53±9 years (mean±SD), respectively, with each group comprising 118 males and 28 females. The basal laboratory data, distribution of Child-Pugh class, HBeAg positivity (31.5% vs. 37.7%), HBV DNA level (5.74±2.35 vs. 5.98±2.29 log10 copies/mL), and proportion with a lifetime alcohol intake of more than 292 kg (30.8% vs. 34.9%) did not differ between cases and controls. The cumulative alcohol intake and the proportion of heavy drinkers did not differ between the two groups in male patients. Conclusions Alcohol intake might not increase the risk of HCC in patients with HBV infection.

Abstract
BACKGROUND & AIMS The accurate identification of inactive (serum HBV-DNA persistently <or=2000 IU/mL) hepatitis B virus (HBV) carriers (IC) is difficult because of wide and frequent HBV-DNA fluctuations. We studied whether hepatitis B surface antigen (HBsAg) serum levels (HBsAgsl) quantification may contribute to diagnosis of HBV phases in untreated hepatitis B e antigen-negative genotype D asymptomatic carriers. METHODS HBsAgsl were measured at baseline and end of follow-up and correlated with virologic and biochemical profiles of 209 consecutive carriers followed-up prospectively (median, 29; range, 12-110 months). HBV phases were defined after 1-year monthly monitoring of HBV-DNA and transaminases. RESULTS HBsAgsl were significantly lower in 56 inactive carriers (IC) than 153 active carriers (AC): median, 62.12 (range, 0.1-4068) vs median, 3029 (range, 0.5-82,480) IU/mL; P<.001. Among AC, HBsAgsl were lower in 31 AC whose viremia remained persistently <20,000 IU/mL (AC1) than in 122 AC with fluctuations>or=20,000 IU/mL (AC2): 883 (0.5-7838) vs 4233 (164-82,480) IU/mL, P=.002. HBV infection was less productive in IC and AC1 than AC2 (log10 HBV-DNA/HBsAgsl ratios 0.25 and 0.49 vs 2.06, respectively, P<.001) and in chronic hepatitis than cirrhosis (1.97 vs 2.34, respectively; P=.023). The combined single point quantification of HBsAg (<1000 IU/mL) and HBV-DNA (<or=2000 IU/mL) identified IC with 94.3% diagnostic accuracy, 91.1% sensitivity, 95.4% specificity, 87.9% positive predictive value, 96.7% negative predictive value. During follow-up, HBsAgsl were stable in AC but declined in IC (yearly median decline, -0.0120 vs -0.0768 log10 IU/mL, respectively, P<.001), 10 of whom cleared HBsAg. CONCLUSIONS HBsAgsl vary during chronic hepatitis B e antigen-negative genotype D infection and are significantly lower in IC. Single-point combined HBsAg and HBV-DNA quantification provides the most accurate identification of IC, comparable with that of long-term tight monitoring.

Abstract
Vitamin D exhibits immunomodulatory and antiproliferative effects through vitamin D receptor (VDR) in chronic infections and cancers. We genotyped the BsmI (rs1544410), ApaI (rs7975232) and TaqI (rs731236) polymorphisms of VDR gene in 250 Taiwanese chronic hepatitis B virus (HBV) carriers who were categorized into six phenotypes. After adjustment for age and sex, the frequencies of the VDR B/b, B/a, B/T, B/a/T in patients with hepatitis flare(s) were lower than those without (7 vs 20%, P=0.009; 1 vs 9%, P=0.004; 3 vs 10%, P=0.007; 1 vs 9%, P=0.005, respectively); in contrast, T/t, A/T, A/t, b/A/t were higher in flare(s) (8 vs 3%, P=0.003; 49 vs 34%, P=0.027; 2 vs 1%, P=0.004; 0.5 vs 0%, P=0.001, respectively). In addition, B/b, B/B, T/t, b/A, B/a, B/A, B/T, B/t, A/t, b/A/T, B/a/T, B/A/T, B/A/t, b/A/t were higher in patients positive for HBeAg. The distribution of VDR genotypes was comparable between patients with and without hepatocellular carcinoma (HCC). VDR gene polymorphisms are associated with distinct clinical phenotypes in Taiwanese HBV carriers but not with HCC development.

Abstract
The goal of antiviral therapy in HBV cirrhotic patients is to prevent progression of the disease to decompensated cirrhosis, end-stage liver disease, hepatocellular carcinoma and death. This goal can be achieved if HBV replication can be suppressed, leading to biochemical remission, histological improvement and prevention of complications. If finite treatment with pegylated interferon is not contraindicated in compensated cirrhosis, long-term treatment with nucleoside/nucleotide analogues is recommended in patients with HBV-related cirrhosis, especially in decompensated cirrhosis. Patients with cirrhosis require careful monitoring to detect resistance and prevent flares, and also to screen for hepatocellular carcinoma, portal hypertension and liver failure.

Abstract
OBJECTIVES The clinical significance of liver steatosis has been studied because steatosis plays a role in the progression of liver fibrosis. Nevertheless, the impact of steatosis in the early stage of fibrosis in non-obese young men with chronic hepatitis B (CHB) is poorly understood. Thus, the purpose of this study was to investigate the prevalence of hepatic steatosis, assess the relationship between hepatic steatosis and fibrosis and to assess the laboratory parameters for predicting clinically significant liver fibrosis in non-obese young men with CHB. METHODS We prospectively evaluated liver biopsies in young male patients with CHB with a serum alanine aminotransferase level of more than two times the upper limit of normal for at least 3 months before enrollment. Patients were excluded when they had co-infection with another virus and prior antiviral treatment. Demographical, anthropometric and laboratory parameters were analysed. Liver steatosis, necroinflammation and fibrosis were also assessed. RESULTS A total of 86 young male patients with CHB were included in this study. The median age was 21 years (range, 20-26 years) and the median body mass index was 23.0 kg/m2 (range, 18.0-28.3 kg/m2). Steatosis was present in 44 patients (51.2%). Significant fibrosis (beyond periportal fibrosis) was present in 50 patients (58.1%). Steatosis was associated with insulin, homeostasis model for insulin resistance (HOMA-IR), total cholesterol and triglycerides. On multiple regression analysis, steatosis was independently associated with triglyceride and HOMA-IR. Significant fibrosis was independently associated with gamma-glutamyltransferase (GGT) and necroinflammation activity. However, there was no significant association between significant fibrosis and the presence of steatosis. CONCLUSIONS The prevalence of hepatic steatosis is a common finding in young male patients with CHB. Hepatic steatosis in CHB patients seems to be associated with insulin resistance, but it is not associated with hepatic fibrosis. GGT levels can provide useful information on the stage of CHB.

Abstract
OBJECTIVES It is still debated whether hepatitis B virus (HBV) infection is associated with the development of diabetes. Our primary objective was to determine whether insulin resistance is associated with HBV-induced histologic severity. METHODS This study included consecutive 80 nondiabetic, noncirrhotic patients with HBV infection who underwent liver biopsy. We evaluated the relationship between histologic findings and clinical parameters and insulin resistance determined by the homeostasis model assessment (HOMA-IR). RESULTS Patients with minimal fibrosis (stage 0 or 1) had significantly higher levels of insulin and HOMA-IR (P = 0.004, P = 0.028, respectively) compared with matched healthy controls. HOMA-IR is independently associated with body mass index (coefficient, 0.16; 95% confidence interval, CI, 0.03-0.28) but not with HBV-induced histologic activity or fibrosis. Insulin resistance was not significantly different among patients with or without significant fibrosis (stage 2 or 3). In multivariate analysis, Hepatitis B e antigen (HBeAg) positivity (odds ratio, OR, 0.04; 95% CI, 0.01-0.31) and portal/periportal inflammation (OR, 18.6; 95% CI, 3.9-88.2) were independent predictors of significant fibrosis. CONCLUSIONS The observed hyperinsulinemia in HBV-infected patients seems to be from altered insulin metabolism rather than HBV-specific effects. Insulin resistance is not associated with significant fibrosis. The data suggest that hepatic fibrosis in HBV-infected patients is attributable to the virus-induced liver injury, but not to insulin resistance.

Abstract
Human leukocyte antigen (HLA) class II molecules are associated with host immune responses against hepatitis B virus infection. Male gender is the apparent host factor when someone encounters with the severity of hepatitis. The aim of this study was to investigate the association of the most polymorphic HLA class II allele, human leukocyte antigen-DRB1, with the severity of hepatitis in male carriers of hepatitis B virus. In this prospective cohort study, a total of 204 carriers of hepatitis B virus (131 men and 73 women) who have been followed-up for more than 1 year at the outpatient clinic of a university hospital were collected consecutively. Fifty carriers of hepatitis B virus (group I) with alanine aminotransferase <2x upper limit of normal (mean follow-up 83.6 months) were compared with 154 chronic hepatitis B patients (group II) with alanine aminotransferase >/=2x upper limit of normal (mean follow-up 81.3 months). Alleles of HLA-DRB1 were typed by the polymerase chain reaction-sequence specific oligonucleotide probe hybridization and genotypes of hepatitis B virus by melting curve analysis. HLA-DRB1*1101 was found in 18% of group I versus 8% of group II in male carriers (OR 0.23, P = 0.020, after adjustment for age) and 4% versus 9.4% in female carriers (P = 0.094). In male carriers harboring DRB1*1101, the distribution of hepatitis B viral genotype was comparable between the two groups. HLA-DRB1*1101 correlates with less severe hepatitis in Taiwanese male carriers of hepatitis B virus.

Abstract
The natural history of chronic hepatitis B virus (HBV) infection and disease is complex and highly variable. We review the natural history of chronic hepatitis B with emphasis on the rates of disease progression and factors influencing the course of the liver disease. Chronic hepatitis B is characterized by an early replicative phase (HBeAg positive chronic hepatitis) and a late low or non-replication phase with HBeAg seroconversion and liver disease remission (inactive carrier state). Most patients become inactive carriers after spontaneous HBeAg seroconversion with good prognosis, but progression to HBeAg negative chronic hepatitis due to HBV variants not expressing HBeAg occurs at a rate of 1-3 per 100 person years following HBeAg seroconversion. The incidence of cirrhosis appears to be about 2-fold higher in HBeAg negative compared to HBeAg positive chronic hepatitis. In the cirrhotic patient the 5-year cumulative risk of developing hepatocellular carcinoma is 17% in East Asia and 10% in the Western Europe and the United States and the 5-year liver related death rate is 15% in Europe and 14% in East Asia. There is a growing understanding of viral, host and environmental factors influencing disease progression, which ultimately could improve the management of chronic hepatitis B.

Abstract
Hepatitis B virus (HBV) is the most common cause of chronic hepatitis and end-stage liver disease worldwide. Untreated, chronic hepatitis B acquired early in life results in cirrhosis, liver failure, or hepatocellular carcinoma in up to 40% of individuals. Until recently, the options for a patient who had end-stage hepatitis B cirrhosis were severely limited, but during the past 15 years great strides have been made in prevention and treatment of hepatitis B cirrhosis. This article reviews recent advances in the understanding of the natural history, prevention, and medical management of HBV-related end-stage liver disease.

Abstract
Chronic hepatitis B virus (HBV) infection is the most common cause of hepatic fibrosis and hepatocellular carcinoma (HCC), mainly as a result of chronic necroinflammatory liver disease. A characteristic feature of chronic hepatitis B infection, alcoholic liver disease and nonalcoholic fatty liver disease (NAFLD) is hepatic steatosis. Hepatic steatosis leads to an increase in lipid peroxidation in hepatocytes, which, in turn, activates hepatic stellate cells (HSCs). HSCs are the primary target cells for inflammatory and oxidative stimuli, and these cells produce extracellular matrix components. Chronic hepatitis B appears to progress more rapidly in males than in females, and NAFLD, cirrhosis and HCC are predominately diseases that tend to occur in men and postmenopausal women. Premenopausal women have lower hepatic iron stores and a decreased production of proinflammatory cytokines. Hepatic steatosis has been observed in aromatase-deficient mice, and has been shown to decrease in animals after estradiol treatment. Estradiol is a potent endogenous antioxidant which suppresses hepatic fibrosis in animal models, and attenuates induction of redox sensitive transcription factors, hepatocyte apoptosis and HSC activation by inhibiting a generation of reactive oxygen species in primary cultures. Variant estrogen receptors are expressed to a greater extent in male patients with chronic liver disease than in females. These lines of evidence suggest that the greater progression of hepatic fibrosis and HCC in men and postmenopausal women may be due, at least in part, to lower production of estradiol and a reduced response to the action of estradiol. A better understanding of the basic mechanisms underlying the sex-associated differences in hepatic fibrogenesis and carciogenesis may open up new avenues for the prevention and treatment of chronic liver disease.

Abstract
BACKGROUND AND AIM This study evaluated the long-term outcome and prognostic factors of chronic hepatitis B, based on histological grade and stage. METHODS A total of 188 patients with chronic hepatitis B were followed for a mean 119.8 months. Ultrasonography and clinical assessment were performed regularly. In addition, liver biopsy specimens were re-evaluated based on histological grade and stage. RESULTS During follow-up, cirrhosis developed in 62 patients, decompensation in 20 patients, and hepatocellular carcinoma (HCC) in 21 patients. The serum alanine aminotransferase (ALT) level at the time of liver biopsy was significantly correlated with the grades of lobular and porto-periportal activity. The development of cirrhosis correlated well with the grade of porto-periportal activity and stage of fibrosis. The probabilities of developing cirrhosis, decompensation and HCC were significantly higher in patients whose ALT levels were persistently elevated without flares or flared-up without normalization than in patients whose ALT levels flared-up then normalized or were normally sustained. By multivariate analysis, age and biochemical profile during follow-up were independent prognostic factors for chronic hepatitis B. CONCLUSIONS The results demonstrate that histological grade and stage, and biochemical profile during follow-up in patients with chronic hepatitis B are important prognostic factors. Therefore, effective control of hepatitis activity might improve the long-term outcome of chronic hepatitis B patients.

Abstract
BACKGROUND & AIMS Cirrhosis develops as a result of hepatic inflammation and subsequent fibrosis in chronic hepatitis B infection. We report on the relationship between hepatitis B viremia and progression to cirrhosis in chronic hepatitis B infection. METHODS This was a population-based prospective cohort study of 3582 untreated hepatitis B-infected patients established in Taiwan from 1991 to 1992. Serum samples were tested for HBV DNA on cohort entry serum samples and the diagnosis of cirrhosis was by ultrasound. RESULTS During a mean follow-up time of 11 years, the 3582 patients contributed 40,038 person-years of follow-up evaluation and 365 patients were newly diagnosed with cirrhosis. The cumulative incidence of cirrhosis increased with the HBV-DNA level and ranged from 4.5% to 36.2% for patients with a hepatitis B viral load of less than 300 copies/mL and 10(6) copies/mL or more, respectively (P < .001). In a Cox proportional hazards model adjusting for hepatitis B e-antigen status and serum alanine transaminase level among other variables, hepatitis B viral load was the strongest predictor of progression to cirrhosis relative risk [95% confidence interval] was 2.5 [1.6-3.8]; 5.6 [3.7-8.5]; and 6.5 [4.1-10.2] for HBV-DNA levels >/=10(4) - <10(5); >/=10(5) - <10(6); >/=10(6) copies/mL, respectively. CONCLUSIONS These data show that progression to cirrhosis in hepatitis B-infected persons is correlated strongly with the level of circulating virus. The risk for cirrhosis increases significantly with increasing HBV-DNA levels and is independent of hepatitis B e-antigen status and serum alanine transaminase level.

Abstract
Countries in the the Asia-Pacific region and Africa tend to have the highest prevalence of hepatitis B infection worldwide. Hepatitis B infection progresses from an asymptomatic persistently infected status to chronic hepatitis B, cirrhosis, decompensated liver disease and/or hepatocellular carcinoma. The aim of this review was to summarize rates and risk factors for progression between disease states in the Asia-Pacific region and Africa. A literature search was conducted employing MEDLINE and EMBASE (1975-2003) using the following key words: hepatitis B, natural history, disease progression, cirrhosis, hepatocellular carcinoma, mortality, Africa and the Asia-Pacific region. Bibliographies of articles reviewed were also searched. Ranges for annual progression rates were: (i) asymptomatic persistent infection to chronic hepatitis B, 0.84-2.7%; (ii) chronic hepatitis B to cirrhosis, 1.0-2.4%; and (iii) cirrhosis to hepatocellular carcinoma, 3.0-6.6%. Patients with asymptomatic persistent infection and chronic hepatitis B had relatively low 5-year mortality rates (<4%); rates (>50%) were much higher in patients with decompensated liver disease and hepatocellular carcinoma. No data were found for progression rates in African populations. Hepatitis B e antigen was a risk factor for chronic hepatitis B, and bridging hepatic necrosis in chronic hepatitis B increased the risk of cirrhosis. Risk factors for hepatocellular carcinoma included cirrhosis, co-infection with hepatitis C virus, and genetic and environmental factors. In this review, wide ranges of disease progression estimates are documented, emphasizing the need for further studies, particularly in Africa, where progression rates are largely not available. Summarizing information on factors associated with disease progression should assist in focusing efforts to arrest the disease process in those at most risk.

Abstract
BACKGROUND Natural history studies of hepatitis B virus infection have shown relapse of hepatitis in 5% to 15% of patients and progression to cirrhosis in 2% to 6% annually. Follow-up of patients beginning at the early phase of infection might provide data with less referral bias than in previous studies. METHODS Test of liver biochemistry, assessment of virological markers, and ultrasound examinations were performed at regular intervals during the course of hepatitis B e antigen (HBeAg) to antibody (anti-HBe) seroconversion in 240 HBeAg carriers with normal alanine aminotransferase levels at baseline. Factors predictive of cirrhosis were identified by multivariate analysis. RESULTS We enrolled 130 men and 110 women. The mean (+/- SD) age at entry was 27.6 +/- 6.2 years. During the HBeAg-positive phase, 29% of patients had alanine aminotransferase levels > or =200 U/L, 3% had bilirubin levels > or =2.0 mg/dL, and 5% had two or more episodes of alanine aminotransferase levels > or =200 U/L. The mean age at anti-HBe seroconversion was 31.3 +/- 7.0 years, with remission of hepatitis in all patients. However, hepatitis recurred in 36 patients (15%), with an annual rate of 2.2%. Thirteen patients (5%) progressed to cirrhosis. The annual incidence of cirrhosis was 0.5%, and the cumulative probability of cirrhosis after 17 years was 12.6%. Age at anti-HBe seroconversion and relapse of hepatitis were independent risk factors for cirrhosis. CONCLUSION The clinical severity of chronic hepatitis B was milder in this cohort than in previous studies. Delayed HBeAg seroconversion and relapse of hepatitis were associated with increased risk of cirrhosis.

Abstract
BACKGROUND/AIMS There is considerable variability in the rate of fibrosis progression in patients with chronic hepatitis C, most of which is related to factors so far unknown. We tested the hypothesis that high serum glucose and overweight might contribute to this variability. METHODS Seven hundred and ten patients with chronic hepatitis C with a known duration of infection and no hepatitis B virus or human immunodeficiency virus coinfection were studied. Significant fibrosis was defined as bridging fibrosis including cirrhosis. Variables were tested for their association with significant fibrosis. RESULTS In univariate analyses both serum glucose and body mass index were associated with fibrosis. In multivariate analyses, age at infection, duration of infection, serum glucose and daily alcohol intake but not body mass index were independently associated with significant fibrosis. Patients with high serum glucose had been contaminated at an older age and had features of the metabolic syndrome, including steatosis more frequently, as well as faster fibrosis progression rates. High serum glucose was associated with intermediate and advanced, but not with early, fibrosis stages. A high serum glucose was associated with a higher relative risk for significant fibrosis than overweight. CONCLUSIONS High serum glucose, is an independent co-factor of fibrosis in chronic hepatitis C with a higher pro-fibrogenic impact than overweight.
