Abstract
Liver cancer, a chronic non-communicable disease, represents a serious public health problem. Long-term trends in the burden of liver cancer disease are heterogeneous across regions. Incidence and mortality of liver cancer, based on the Global Burden of Disease, were collected from the Chinese Centre for Disease Control and Prevention. Age-period-cohort model was utilized to reveal the secular trends and estimate the age, period and cohort effects on primary liver cancer due to specific etiologies. Both the age-standardized incidence and mortality rate of liver cancer in Hubei province were on the rise, although there were discrepancies between gender groups. From age-period-cohort analysis, both incidence and mortality of liver cancer due to Hepatitis B virus were the highest in all age groups. The incidence of all liver cancer groups increased with time period in males, while this upward trend was observed in females only in liver cancer due to alcohol use group. Cohort effects indicated the disease burden of liver cancer decreased with birth cohorts. Local drifts showed that the incidence of liver cancer due to specific etiologies was increasing in the age group of males between 40 and 75 years old. The impact of an aging population will continue in Hubei Province. the disease burden of liver cancer will continue to increase, and personalized prevention policies must be adopted to address these changes.

Abstract
Background Worldwide, more than 39 million individuals are living with human immunodeficiency virus (HIV), 296 million with chronic hepatitis B (HBV), and 58 million with chronic hepatitis C (HCV). Despite successful treatments for these blood-borne viruses (BBVs), >1.7 million people die per annum. To combat this, the World Health Organization recommended implementing triple testing for HIV, HBV, and HCV. This systematic review aims to provide evidence for this policy, by identifying the prevalence of these BBVs and discussing the costs of available triple tests. Methods Medline, Embase, and Global Health were searched to identify articles published between 1 January and 24 February 2023. Included studies reported the prevalence of HIV (anti-HIV 1/2 antibodies), HBV (hepatitis B surface antigen) and HCV (anti-HCV antibodies). Results were stratified into risk groups: blood donors, general population, healthcare attendees, individuals experiencing homelessness, men who have sex with men, people who use drugs, pregnant people, prisoners, and refugees and immigrants. Results One hundred seventy-five studies sampling >14 million individuals were included. The mean prevalence of HIV, HBV, and HCV was 0.22% (standard deviation [SD], 7.71%), 1.09% (SD, 5.80%) and 0.65% (SD, 14.64%) respectively. The mean number of individuals testing positive for at least 1 BBV was 1.90% (SD, 16.82%). Therefore, under triple testing, for every individual diagnosed with HIV, another 5 would be diagnosed with HBV and 3 with HCV. Testing for all 3 viruses is available for US$2.48, marginally more expensive than the lowest-priced isolated HIV test ($1.00). Conclusions This article highlights a potential avenue for healthcare improvement by implementing combination testing programs. Hopefully, this will help to achieve the Sustainable Development Goal of elimination of these BBV epidemics by 2030.

Abstract
BACKGROUND & AIMS The available risk stratification indices for hepatocellular cancer (HCC) have limited applicability. We developed and externally validated an HCC risk stratification index in U.S. cohorts of patients with cirrhosis. METHODS We used data from 2 prospective U.S. cohorts to develop the risk index. Patients with cirrhosis were enrolled from 8 centers and followed until development of HCC, death, or December 31, 2021. We identified an optimal set of predictors with the highest discriminatory ability (C-index) for HCC. The predictors were refit using competing risk regression and its predictive performance was evaluated using the area under the receiver-operating characteristic curve (AUROC). External validation was performed in a cohort of 21,550 patients with cirrhosis seen in the U.S Veterans Affairs system between 2018 and 2019 with follow-up through 2021. RESULTS We developed the model in 2431 patients (mean age 60 years, 31% women, 24% cured hepatitis C, 16% alcoholic liver disease, and 29% nonalcoholic fatty liver disease). The selected model had a C-index of 0.77 (95% confidence interval [CI], 0.73-0.81), and the predictors were age, sex, smoking, alcohol use, body mass index, etiology, α-fetoprotein, albumin, alanine aminotransferase, and platelet levels. The AUROCs were 0.75 (95% CI, 0.65-0.85) at 1 year and 0.77 (95% CI, 0.71-0.83) at 2 years, and the model was well calibrated. In the external validation cohort, the AUROC at 2 years was 0.70 with excellent calibration. CONCLUSION The risk index, including objective and routinely available risk factors, can differentiate patients with cirrhosis who will develop HCC and help guide discussions regarding HCC surveillance and prevention. Future studies are needed for additional external validation and refinement of risk stratification.

Abstract
INTRODUCTION There are limited longitudinal data on the cost of treating patients with cirrhosis, which hampers value-based improvement initiatives. METHODS We conducted a retrospective cohort study of patients with cirrhosis seen in the Veterans Affairs health care system from 2011 to 2015. Patients were followed up through 2019. We identified a sex-matched and age-matched control cohort without cirrhosis. We estimated incremental annual health care costs attributable to cirrhosis for 4 years overall and in subgroups based on severity (compensated, decompensated), cirrhosis complications (ascites, encephalopathy, varices, hepatocellular cancer, acute kidney injury), and comorbidity (Deyo index). RESULTS We compared 39,361 patients with cirrhosis with 138,964 controls. The incremental adjusted costs for caring of patients with cirrhosis were $35,029 (95% confidence interval $32,473-$37,585) during the first year and ranged from $14,216 to $17,629 in the subsequent 3 years. Cirrhosis complications accounted for most of these costs. Costs of managing patients with hepatic encephalopathy (year 1 cost, $50,080) or ascites ($50,364) were higher than the costs of managing patients with varices ($20,488) or hepatocellular cancer ($37,639) in the first year. Patients with acute kidney injury or those who had multimorbidity were the most costly at $64,413 and $66,653 in the first year, respectively. DISCUSSION Patients with cirrhosis had substantially higher health care costs than matched controls and multimorbid patients had even higher costs. Cirrhosis complications accounted for most of the excess cost, so preventing complications has the largest potential for cost saving and could serve as targets for improvement.

Abstract
Background Hepatocellular carcinoma (HCC) is the main cause of mortality from cancer globally. This paper intends to classify public gene expression data of patients with Hepatitis C virus-related HCC (HCV+HCC) and chronic HCV without HCC (HCV alone) through the XGboost approach and to identify key genes that may be responsible for HCC. Methods The current research is a retrospective case-control study. Public data from 17 patients with HCV+HCC and 35 patients with HCV-alone samples were used in this study. An XGboost model was established for the classification by 10-fold cross-validation. Accuracy (AC), balanced accuracy (BAC), sensitivity, specificity, positive predictive value, negative predictive value, and F1 score were utilized for performance assessment. Results AC, BAC, sensitivity, specificity, positive predictive value, negative predictive value, and F1 scores from the XGboost model were 98.1, 97.1, 100, 94.1, 97.2, 100, and 98.6%, respectively. According to the variable importance values from the XGboost, the HAO2, TOMM20, GPC3, and PSMB4 genes can be considered potential biomarkers for HCV-related HCC. Conclusion A machine learning-based prediction method discovered genes that potentially serve as biomarkers for HCV-related HCC. After clinical confirmation of the acquired genes in the following medical study, their therapeutic use can be established. Additionally, more detailed clinical works are needed to substantiate the significant conclusions in the current study.

Abstract
In endemic areas, hepatitis C virus (HCV)/hepatitis B virus (HBV) coinfection is common, and patients with coinfection have a higher risk of developing liver disease such as hepatocellular carcinoma, liver fibrosis and cirrhosis. In such cases, HCV predominates, and HBV replication is suppressed by HCV. HCV core proteins and interferons that are activated by HCV are responsible for the suppression of HBV. Immunosuppression is also seen in patients with HCV and HBV coinfections. A decrease in HCV-neutralizing antibody response and circulation of Th1-like Tfh cells is observed in patients with HCV and HBV coinfection. Both viruses interacted in the liver, and treatment of HCV/HBV coinfection is genotype-based and complex due to the interaction of both viruses. In HCV-dominant cases, direct-acting antiviral drugs and peg interferon plus ribavirin are used for the treatment, with continuous monitoring of AST and ALT. HBV-dominant cases are less common and are treated with peg interferon and nucleoside nucleotide analogues with monitoring of AST and ALT. The SVR rate in HCV-HBV coinfection is higher than that in monoinfection when treated with direct-acting antiviral drugs. But there is a risk of reactivation of HBV during and after therapy. The rate of reactivation is lower in patients treated with direct-acting antiviral drugs as compared to those treated with peg interferon plus ribavirin. Biomarkers of HBV such as HBcrAg, HBV DNA and HBVpg RNA are not effective in the prediction of HBV reactivation; only the hepatitis B surface antigen titre can be used as a biomarker for HBV reactivation. HCV can also be reactive, but this is found in very rare cases in which HBV is present and is treated first.

Abstract
Chronic hepatitis B virus (HBV) infection can lead to substantial morbidity and mortality. Although treatment is not considered curative, antiviral treatment, monitoring, and liver cancer surveillance can reduce morbidity and mortality. Effective vaccines to prevent hepatitis B are available. This report updates and expands CDC's previously published Recommendations for Identification and Public Health Management of Persons with Chronic Hepatitis B Virus Infection (MMWR Recomm Rep 2008;57[No. RR-8]) regarding screening for HBV infection in the United States. New recommendations include hepatitis B screening using three laboratory tests at least once during a lifetime for adults aged ≥18 years. The report also expands risk-based testing recommendations to include the following populations, activities, exposures, or conditions associated with increased risk for HBV infection: persons incarcerated or formerly incarcerated in a jail, prison, or other detention setting; persons with a history of sexually transmitted infections or multiple sex partners; and persons with a history of hepatitis C virus infection. In addition, to provide increased access to testing, anyone who requests HBV testing should receive it, regardless of disclosure of risk, because many persons might be reluctant to disclose stigmatizing risks.

Abstract
BACKGROUND AND AIMS Etiological risk factors for cirrhosis have changed in the last decade. It remains unclear to what extent these trends in cirrhosis risk factors have changed HCC risk. APPROACH AND RESULTS We used data from two contemporary, prospective multiethnic cohorts of patients with cirrhosis: the Texas Hepatocellular Carcinoma Consortium Cohort and the Houston Veterans Administration Cirrhosis Surveillance Cohort. Patients with cirrhosis were enrolled from seven US centers and followed until HCC diagnosis, transplant, death, or June 30, 2021. We calculated the annual incidence rates for HCC and examined the effects of etiology, demographic, clinical, and lifestyle factors on the risk of HCC. We included 2733 patients with cirrhosis (mean age 60.1 years, 31.3% women). At enrollment, 19.0% had active HCV, 23.3% had cured HCV, 16.1% had alcoholic liver disease, and 30.1% had NAFLD. During 7406 person-years of follow-up, 135 patients developed HCC at an annual incidence rate of 1.82% (95% CI, 1.51-2.13). The annual HCC incidence rate was 1.71% in patients with cured HCV, 1.32% in patients with alcoholic liver disease, and 1.24% in patients with NAFLD cirrhosis. Compared to patients with NAFLD, the risk of progression to HCC was 2-fold higher in patients with cured HCV (HR, 2.04; 95% CI, 1.24-3.35). Current smoking (HR, 1.63; 95% CI, 1.01-2.63) and overweight/obesity (HR, 1.79; 95% CI, 1.08-2.95) were also associated with HCC risk. CONCLUSIONS HCC incidence among patients with cirrhosis was lower than previously reported. HCC risk was variable across etiologies, with higher risk in patients with HCV cirrhosis and lower risk in those with NAFLD cirrhosis. Current smoking and overweight/obesity increased HCC risk across etiologies.

Abstract
BACKGROUND Polygenic risk scores (PRS) hold the promise to refine prognostication in hepatocellular cancer (HCC). The few available HCC PRS include germline risk variants identified among individuals of mostly European ancestry, but data are lacking on the transportability of these PRS in multiethnic U.S patients with cirrhosis from multiple etiologies. METHODS We used data from 1644 patients with cirrhosis enrolled in two prospective cohort studies in the U.S. Patients were followed until HCC diagnosis, death, liver transplantation, or last study visit through June 30, 2021. The high-risk variants in PNPLA3-MBOAT7-TM6SF2-GCKR were combined in a PRS and we evaluated its association with HCC. Discriminatory accuracy was assessed using the C-statistic. RESULTS During 4,759 person-years of follow-up, 93 patients developed HCC. Mean age was 59.8 years, 68.6% were male, 27.2% Hispanic, 25.1% non-Hispanic Black, 25.7% had NAFLD, 42.1% had heavy alcohol use, and 19.5% had active HCV. HCC risk increased by 134% per unit increase in PRS (HR = 2.30; 95% CI, 1.35-3.92). Compared to cirrhosis patients in the lowest tertile of the PRS, those in the highest tertile had 2-fold higher risk of HCC (HR = 2.05; 95% CI, 1.22-3.44). The PRS alone had modest discriminatory ability (C-statistic = 0.58; 95% CI, 0.52-0.63); however, adding PRS to a predictive model with traditional HCC risk factors had a C-statistic of 0.70 (95% CI, 0.64-0.76), increasing from 0.68 without the PRS (p = 0.0012). CONCLUSIONS Our findings suggest that PRS may enhance risk prediction for HCC in contemporary U.S. cirrhosis patients.

Abstract
The occurrence of hepatocellular carcinoma (HCC) is one of the most serious complications of hepatitis C virus (HCV) infection. Recently, effective antiviral medications have made sustained viral response (SVR) or cure a realistic therapeutic goal for most chronic HCV patients. Given HCV's tumorigenic propensity, it is not surprising that achieving SVR is helpful in preventing HCC. This review briefly summarizes and discusses the existing evidence on the relationship between hepatic carcinogenesis and viral eradication by antivirals, which is mainly divided into interferon-based and direct-acting antivirals (DAAs) based therapy. DAAs have changed the treatment landscape of chronic HCV, reaching high rates of SVR even in patients with advanced cirrhosis, with few contraindications and little side effects. Although some early reports suggested that DAA treatment increased the chance of HCC occurrence, more subsequent observational studies have refuted this theory. The probability of HCC recurrence after HCV eradication appears to be decreasing over time following SVR. Despite virological suppression/cure, individuals with liver cirrhosis are still at risk of HCC and should be monitored. There is a considerable need for markers/scores to predict the long-term risk of HCC in patients with HCV-related liver disease who attain SVR with direct-acting antivirals.

Abstract
Background: To evaluate prognostic value of WTAP levels in tumor and paired adjacent non-neoplastic liver tissues (PANLT) for cases of hepatitis B virus (HBV)-positive Asian small hepatocellular carcinoma (sHCC) patients who received curative partial hepatectomy. Method: The investigation with two external cohorts were included. Associations between hazard risk of recurrence and continuous WTAP levels were investigated with restricted cubic spline models. Cox and inverse probability weighting models were established for survival analysis. Based on interaction effects, further stratification analysis was performed. Landmark analysis was employed to analyze cases of late recurrence. Finally, sensitivity analysis was performed to assess unmeasured confounders. Findings: In an investigation cohort of 307 patients, restricted cubic spline models indicated that hazard risk of recurrence increases with elevated WTAP levels for sHCC and PANLT. However, using Cox and inverse probability weighting models, no significant differences were observed in recurrence-free survival (RFS) between groups with different WTAP levels in sHCC. Multivariate analysis showed that patients with high PANLT WTAP levels had significantly worse RFS (HR 1.567, 95% CI 1.065-2.307; p = 0.023). Based on the significant interaction effect between WTAP levels in sHCC and PANLT, stratification analysis revealed that recurrence risk is more pronounced in patients with high WTAP levels in both PANLT and sHCC. Landmark analysis showed that late recurrence was more likely to occur in patients with high PANLT WTAP levels (HR 2.058, 95% CI 1.113-3.805; p = 0.021). Moreover, the detrimental effects of elevated PANLT WTAP levels on RFS were validated with two external cohorts. Sensitivity analysis confirmed the robustness of results. Conclusion: Increased PANLT WTAP expression levels independently predict high recurrence risk in HBV-positive Asian sHCC patients. Both tumor tissues and PANLT need to be considered together in future clinical practice to obtain a more comprehensive and accurate evaluation for recurrence risk.

Abstract
Transmission of hepatitis B virus (HBV) and hepatitis C virus (HCV) is similar regarding the mode of transmission and related risk factors. Therefore, it is not rare to encounter dual HBV/HCV infection in populations at risk of parenteral exposure to hepatitis viruses. Besides, in HBV endemic countries before the era of global HBV vaccination, dual HBV/HCV infection was clinically significant likely because of HCV superinfection over pre-existing HBsAg carriage. Universal childhood HBV vaccination was implemented worldwide since 1992. Public education programs for prevention of new hepatitis viral infections have been actively promoted recently by World Health Organization. Apart from preventive measures, potent anti-HBV agents effective in the control of viral replication have been introduced gradually in the past three decades. Direct acting antiviral agents capable of curing HCV infection in more than 97% of patients with chronic hepatitis C have also been widely implemented in the past decade. These interventions will change the epidemiology of new HBV or HCV mono-infection and dual HBV/HCV infection. Understanding the evolution in the epidemiology of dual HBV/HCV infection is important for evaluation of current public health policy towards infectious disease control in different countries. The changing prevalence of dual HBV/HCV infection in certain Asia-Pacific countries will be re-visited based on endemicity of HBV or HCV, as well as in populations at risk of parenteral viral infection.

Abstract
Chronic hepatitis C infection is a major cause of liver cancer in the United States. Hawai'i's incidence of liver cancer consistently ranks among the highest in the US, due in part to the high prevalence of hepatitis B in the state. To better understand the factors associated with liver cancer among patients in Hawai'i with hepatitis C virus (HCV) infection, the patient database of Kaiser Permanente's Hawai'i region was used to identify a cohort of 3198 patients with a history of chronic HCV infection, of whom 159 (5%) were diagnosed with liver cancer between the years 2004-2020. Multiple logistic regression was used to identify factors independently associated with liver cancer. Male sex (AOR 2.02, 95% CI 1.34-3.06), Asian race (AOR 1.78, 1.16 - 2.74) and hepatitis B core antibody (HBCAB) positivity (AOR 1.76, 95% CI 1.25 - 2.49) emerged as independent predictors of liver cancer among patients with chronic HCV infection. A history of diabetes (AOR 1.56, 1.07 - 2.27) and older age at the time of HCV diagnosis (AOR 1.19, 1.09-1.29) also emerged as significant associations. HBCAB-positive individuals did not differ significantly from those who were HBCAB-negative in regards to demographics or 5-year survival rate. In this cohort of patients with chronic HCV, a positive HBCAB without evidence of active hepatitis B infection was associated with 1.76 increased odds of liver cancer compared to those with negative HBCAB. This finding may have important implications for screening algorithms among individuals with hepatitis C infection.

Abstract
Background and Objectives: Direct-acting antiviral agents (DAA) are a safe and highly effective treatment for hepatitis C virus (HCV) infection. However, the uptake of DAA treatment remains a challenge. This study aims to examine the reasons for DAA refusal among HCV patients covered by the Taiwan National Health Insurance system. Materials and Methods: This retrospective observational study covered the period from January 2009 to December 2019 and was conducted at a single hepatitis treatment center in Taiwan. This study involved chart reviews and phone-based surveys to confirm treatment status and refusal causes. To confirm treatment status, subjects with HCV without treatment records were phone-contacted to confirm treatment status. Patients who did not receive treatment were invited back for treatment. If the patient refused, the reason for refusal was discussed. Results: A total of 3566 patients were confirmed with DAA treatment; 418 patients (179 patients who were lost to contact or refused the survey and 239 patients who completed the survey of DAA refusal) were included in the no-DAA-therapy group. Factors associated with receiving DAAs were hemoglobin levels, hepatitis B virus co-infection, and regular gastroenterology visits. Meanwhile, male sex, platelet levels, and primary care physician visits were associated with DAA refusal. The leading causes of treatment refusal were multiple comorbidities, low health literacy, restricted access to hospitals, nursing home residence, and old age. The rate of DAA refusal remains high (10%). Conclusions: The reasons for treatment refusal are multifactorial, and addressing them requires complex interventions.

Abstract
INTRODUCTION Hepatocellular carcinoma (HCC) is the sixth most common cancer and the third-leading cause of cancer-related mortality in the world. AREAS COVERED This review will discuss risk factors, demographic differences, global trends, and the economic burden of HCC. Viral hepatitis, particularly hepatitis B virus (HBV) infection, is the most common underlying liver disease leading to HCC in those with cirrhosis. Other important risk factors include alcoholic liver disease, nonalcoholic fatty liver disease, metabolic syndrome, etc. With the introduction of direct-acting antiviral agents for hepatitis C virus infection, routine vaccination against HBV, and increasing support for robust public screening programs, the incidence rates for HCC due to viral hepatitis is falling in many countries. Meanwhile, the prevalence of obesity and metabolic syndrome are on the rise, as is NAFLD-related HCC incidence. Asia and Africa have the highest incidence rates of HCC. In multiethnic countries, racial and ethnic minorities experience disparities in HCC incidence as well as mortality, representing an essential area for improvement in terms of healthcare inequity. EXPERT OPINION Interventions to minimize the global burden of HCC aim to reduce rates of the most common risk factors and implement effective treatment of underlying etiology and comprehensive screening programs for HCC.

Abstract
Treatment for hepatitis C virus (HCV) with direct-acting antivirals (DAAs) in hepatitis B virus (HBV) coinfection can result in HBV reactivation. In this issue of the JCI, Cheng and colleagues explored the role of interferon signaling in the complex interaction between HBV and HCV using cell lines, mouse models, and samples from people with coinfection. Notably, HCV enhanced interferon signaling, as measured by interferon-stimulated gene (ISG) expression, and decreased HBV transcription and replication. Blockade of interferon signaling reversed the effects on HBV replication. Further, pharmacologic inhibition of HCV replication in vitro and in coinfected humanized mice also reduced interferon signaling and, correspondingly, increased HBV replication. Intriguingly, baseline serum levels of the ISG CXCL10 predicted HBV reactivation in a cohort of coinfected people taking DAAs. Determining how interferon signaling silences HBV transcription and whether serum CXCL10 predicts HBV reactivation in a clinical setting are questions that warrant further investigation.

Abstract
Liver cancer is a global problem and hepatocellular carcinoma (HCC) accounts for about 85% of this cancer. In the USA, etiologies and risk factors for HCC include chronic hepatitis C virus (HCV) infection, diabetes, non-alcoholic steatohepatitis (NASH), obesity, excessive alcohol drinking, exposure to tobacco smoke, and genetic factors. Chronic HCV infection appears to be associated with about 30% of HCC. Chronic HCV infection induces multistep changes in liver, involving metabolic disorders, steatosis, cirrhosis and HCC. Liver carcinogenesis requires initiation of neoplastic clones, and progression to clinically diagnose malignancy. Tumor progression associates with profound exhaustion of tumor-antigen-specific CD8+T cells, and accumulation of PD-1hi CD8+T cells and Tregs. In this chapter, we provide a brief description of HCV and environmental/genetic factors, immune regulation, and highlight mechanisms of HCV associated HCC. We also underscore HCV treatment and recent paradigm of HCC progression, highlighted the current treatment and potential future therapeutic opportunities.

Abstract
New therapies against hepatitis B virus (HBV) require the elimination of covalently closed circular DNA (cccDNA), the episomal HBV genome. HBV plasmids containing an overlength 1.3-mer genome and bacterial backbone (pHBV1.3) are used in many different models, but do not replicate the unique features of cccDNA. Since the stable cccDNA pool is a barrier to HBV eradication in patients, we developed a recombinant circular HBV genome (rcccDNA) to mimic the cccDNA using Cre/LoxP technology. We validated four LoxP insertion sites into the HBV genome using hydrodynamic tail vein injection into murine liver, demonstrating high levels of HBV surface antigen (HBsAg) and HBV DNA expression with rcccDNA formation. HBsAg expression from rcccDNA was >30,000 ng/mL over 78 days, while HBsAg-expression from pHBV1.3 plasmid DNA declined from 2753 ng/mL to 131 ng/mL over that time in immunodeficient mice (P < 0.001), reflective of plasmid DNA silencing. We then cloned Cre-recombinase in cis on the LoxP-HBV plasmids, achieving plasmid stability in bacteria with intron insertion into Cre and demonstrating rcccDNA formation after transfection in vitro and in vivo. These cis-Cre/LoxP-HBV plasmids were then used to create HBx-mutant and GFP reporter plasmids to further probe cccDNA biology and antiviral strategies against cccDNA. Overall, we believe these auto-generating rcccDNA plasmids will be of great value to model cccDNA for testing new therapies against HBV infection.

Importance Machine-learning algorithms offer better predictive accuracy than traditional prognostic models but are too complex and opaque for clinical use. Objective To compare different machine learning methods in predicting overall mortality in cirrhosis and to use machine learning to select easily scored clinical variables for a novel cirrhosis prognostic model. Design, Setting, and Participants This prognostic study used a retrospective cohort of adult patients with cirrhosis or its complications seen in 130 hospitals and affiliated ambulatory clinics in the integrated, national Veterans Affairs health care system from October 1, 2011, to September 30, 2015. Patients were followed up through December 31, 2018. Data were analyzed from October 1, 2017, to May 31, 2020. Exposures Potential predictors included demographic characteristics; liver disease etiology, severity, and complications; use of health care resources; comorbid conditions; and comprehensive laboratory and medication data. Patients were randomly selected for model development (66.7%) and validation (33.3%). Three different statistical and machine learning methods were evaluated: gradient descent boosting, logistic regression with least absolute shrinkage and selection operator (LASSO) regularization, and logistic regression with LASSO constrained to select no more than 10 predictors (partial pathway model). Predictor inclusion and model performance were evaluated in a 5-fold cross-validation. Last, the predictors identified in the most parsimonious (the partial path) model were refit using maximum-likelihood estimation (Cirrhosis Mortality Model [CiMM]), and its predictive performance was compared with that of the widely used Model for End Stage Liver Disease with sodium (MELD-Na) score. Main Outcomes and Measures All-cause mortality. Results Of the 107 939 patients with cirrhosis (mean [SD] age, 62.7 [9.6] years; 96.6% male; 66.3% white, 18.4% African American), the annual mortality rate ranged from 8.8% to 15.3%. In total, 32.7% of patients died within 3 years, and 46.2% died within 5 years after the index date. Models predicting 1-year mortality had good discrimination for the gradient descent boosting (area under the receiver operating characteristics curve [AUC], 0.81; 95% CI, 0.80-0.82), logistic regression with LASSO regularization (AUC, 0.78; 95% CI, 0.77-0.79), and the partial path logistic model (AUC, 0.78; 95% CI, 0.76-0.78). All models showed good calibration. The final CiMM model with machine learning-derived clinical variables offered significantly better discrimination than the MELD-Na score, with AUCs of 0.78 (95% CI, 0.77-0.79) vs 0.67 (95% CI, 0.66-0.68) for 1-year mortality, respectively (DeLong z = 17.00; P < .001). Conclusions and Relevance In this study, simple machine learning techniques performed as well as the more advanced ensemble gradient boosting. Using the clinical variables identified from simple machine learning in a cirrhosis mortality model produced a new score more transparent than machine learning and more predictive than the MELD-Na score.

Abstract
BACKGROUND The impact of human cytomegalovirus (HCMV) reactivation on the expression pattern of matrix metalloproteinases, their inhibitors and related cytokines during HCV infection poorly understood. METHODS Reactivation of CMV in 95 subjects (75 chronically infected HCV patients and 20 healthy subjects) was examined. All studied subjects had detectable IgG antibodies for CMV, but only 35/75 of HCV patients (46.7%) had detectable CMV DNA. The expressions of 11 fibrosis related genes by quantitative real-time PCR were analyzed in subjects' PBMCs. The serum levels of TGFβ2 and PDGFα have been measured by ELISA. RESULTS Chronically infected HCV patients with reactivated CMV had less expression of TGF-β1, TGF-β2, PDGFα and STAT1 transcripts than HCV patients with latent CMV (p = 0.037, 0.006, 0.001 and 0.009; respectively) and normal controls (TGF-β2, p = 0.008). Moreover the expression of (TGFβ2 and PDGFα) genes decreased significantly in CMV-reactivated patients during the early stage of fibrosis relative to the comparable stage of HCV infection (p = 0.004 and 0.008; respectively). Besides, the mRNA abundance of STAT1 gene in CMV-reactivated patients decreased dramatically as compared to HCV infections during the late stage of fibrosis (p = 0.014). The TGFβ2 protein level has been declined dramatically in CMV-reactivated patients compared to HCV infected patients and control group (p = 0.001 and 0.033; respectively). Our results suggest that CMV reactivation disrupts the expression of several cytokines as compared to solitary infection with HCV. Noticeably, the expressions of matrix metalloproteinases genes and their inhibitors have not been significantly influenced by reactivation of CMV. CONCLUSION The current data reveal that reactivation of CMV partially blocks the upregulation of 2 important pro-inflammatory cytokines i.e. TGFβ 2 and PDGFα at early stages of fibrosis, moreover this CMV mediated blockage of the STAT1 shows statistical significance at late stage of fibrosis.

Abstract
INTRODUCTION active or chronic exacerbated forms of hepatitis C virus (HCV) infection subsequently progress to liver disease and human defensins has been determined to have some level of anti-viral properties invitro whilst the expression of T helper-1 cytokines is known to promote complete recovery from acute HCV infection. The study sought to determine relationship between these immune responses. METHODS a cross sectional descriptive study design was employed. Hundred and thirty-two individuals were assessed were assessed for to anti-HCV, HCV RNA, serum levels of human alpha defensins 1 (HAD-1) and human beta defensins 1 (HBD-1). T helper 1 cytokines (IL-2, IFN gamma, TNF alpha) secreted in serum were also analyzed using commercial ELISA assay. The study was conducted in Kumasi, Obuasi and Daboya in Ghana. RESULTS the serum mean concentrations of HAD-1, HBD-1, IL-2, IFN gamma and TNF alpha showed no significant difference in concentrations among participants with chronic, spontaneously recovered or negative to HCV infection (p>0.05). Persons with hepatitis B co-infection were more likely to develop chronic HCV infection (p=0.039). HAD-1 and HBD-1 showed significant positive association with IL-2 (p=0.000) whilst only HAD-1 positively correlated with IL-2 (p<0.000). CONCLUSION the immunological markers determined had no association with the status of HCV infection. HAD-1 increased with increasing levels of IL-2. These findings suggest that during HCV infection, inflammatory response through the production of cytokines by IL-2 cells may affect the release of HAD-1 and HBD-1.

Abstract
Hepatitis C virus (HCV) infection is the major risk factor for liver cirrhosis and hepatocellular carcinoma (HCC). The mechanisms of HCC initiation, growth, and metastasis appear to be highly complex due to the decade-long interactions between the virus, immune system, and overlapping bystander effects of host metabolic liver disease. The lack of a readily accessible animal model system for HCV is a significant obstacle to understand the mechanisms of viral carcinogenesis. Traditionally, the primary prevention strategy of HCC has been to eliminate infection by antiviral therapy. The success of virus elimination by antiviral treatment is determined by the SVR when the HCV is no longer detectable in serum. Interferon-alpha (IFN-α) and its analogs, pegylated IFN-α (PEG-IFN-α) alone with ribavirin (RBV), have been the primary antiviral treatment of HCV for many years with a low cure rate. The cloning and sequencing of HCV have allowed the development of cell culture models, which accelerated antiviral drug discovery. It resulted in the selection of highly effective direct-acting antiviral (DAA)-based combination therapy that now offers incredible success in curing HCV infection in more than 95% of all patients, including those with cirrhosis. However, several emerging recent publications claim that patients who have liver cirrhosis at the time of DAAs treatment face the risk of HCC occurrence and recurrence after viral cure. This remains a substantial challenge while addressing the long-term benefit of antiviral medicine. The host-related mechanisms that drive the risk of HCC in the absence of the virus are unknown. This review describes the multifaceted mechanisms that create a tumorigenic environment during chronic HCV infection. In addition to the potential oncogenic programming that drives HCC after viral clearance by DAAs, the current status of a biomarker development for early prediction of cirrhosis regression and HCC detection post viral treatment is discussed. Since DAAs treatment does not provide full protection against reinfection or viral transmission to other individuals, the recent studies for a vaccine development are also reviewed.

Abstract
Currently, despite the use of a preventive vaccine for several decades as well as the use of effective and well-tolerated viral suppressive medications since 1998, approximately 250 million people remain infected with the virus that causes hepatitis B worldwide. Hepatitis C virus (HCV) and hepatitis B virus (HBV) are the leading causes of liver cancer and overall mortality globally, surpassing malaria and tuberculosis. Linkage to care is estimated to be very poor both in developing countries and in high-income countries, such as the United States, countries in Western Europe, and Japan. In the United States, by CDC estimates, only one-third of HBV-infected patients or less are aware of their infection. Some reasons for these low rates of surveillance, diagnosis, and treatment include the asymptomatic nature of chronic hepatitis B until the very late stages, a lack of curative therapy with a finite treatment duration, a complex natural history, and a lack of knowledge about the disease by both care providers and patients. In the last 5 years, more attention has been focused on the important topics of HBV screening, diagnosis of HBV infection, and appropriate linkage to care. There have also been rapid clinical developments toward a functional cure of HBV infection, with novel compounds currently being in various phases of progress. Despite this knowledge, many of the professional organizations provide guidelines focused only on specific questions related to the treatment of HBV infection. This focus leaves a gap for care providers on the other HBV-related issues, which include HBV's epidemiological profile, its natural history, how it interacts with other viral hepatitis diseases, treatments, and the areas that still need to be addressed in order to achieve HBV elimination by 2030. Thus, to fill these gaps and provide a more comprehensive and relevant document to regions worldwide, we have taken a global approach by using the findings of global experts on HBV as well as citing major guidelines and their various approaches to addressing HBV and its disease burden.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is the most prevalent form of liver cancer and a leading cause of cancer-related deaths worldwide. The major risk factors for HCC development are chronic liver disease and cirrhosis due to hepatitis B virus (HBV) and/or hepatitis C virus (HCV), alcoholic liver disease, non-alcoholic fatty liver disease (NAFLD), steatohepatitis, intake of aflatoxin-contaminated food, diabetes, and obesity. RESULTS In Western countries, the number of NASH-related HCC cases is increasing, that of HBV- or HCV-related cases is declining due to the wide application of HBV universal vaccination and the introduction of effective therapies against HBV and HCV infections, and that of alcohol-related cases remaining substantially unchanged. Nevertheless, the burden of HCC is expected to increase worldwide in the next few decades, due to the population growth and aging expected in coming years. Overall, the abovementioned changes and future variations in lifestyle and in the impact of environmental factors in Western countries and a decreasing exposure to dietary aflatoxins and improved socio-economic conditions in developing countries will create new HCC epidemiology in the next few decades. CONCLUSION A substantial further reduction in cases of HCC requires a wider application of universal HBV vaccination and effective treatment of HBV- and HCV-related chronic hepatitis and cirrhosis, more effective campaigns to favor correct dietary habits and reduce alcohol consumption and the intensification of studies on HCC pathogenesis for future optimized prevention strategies.

Abstract
BACKGROUND Hepatitis B virus (HBV) infection testing among persons with hepatitis C virus (HCV) infection is necessary to appropriately care for these patients, yet uptake of HBV testing and vaccination in this population is suboptimal. METHODS In a retrospective cohort analysis, we describe the prevalence of hepatitis B testing, linkage to hepatitis B care, and hepatitis B vaccination in patients with HCV infection within a large urban safety-net health system. Using a registry of HCV-infected patients with patient-level electronic health record data, that included demographic, clinical, and laboratory information from 2004 to 2016 from Grady Health System in Atlanta, GA, we describe (1) The prevalence of hepatitis B testing (hepatitis B surface antigen [HBsAg], core antibody [anti-HBc], surface antibody [anti-HBs]); (2) The proportion of HBsAg-positive persons receiving HBV DNA and e-antigen (HBeAg) as indicators for linkage to hepatitis B-directed care; and (3) The proportion of persons receiving hepatitis B vaccine. RESULTS Of 4224 HCV-infected patients, 3629 (86%) had test results for HBsAg and 43 (1.2%) were HBsAg-positive. Of 2342 (55%) with test results for all three HBV serological markers, median age was 60 years, 67% were male, and 83% were African-American, 789 (34%) anti-HBc positive only, 678 (29%) anti-HBc/anti-HBs positive, 190 (8.1%) anti-HBs positive only, and 642 (27%) were HBV-susceptible. Of HBsAg-positive patients, 21% received HBV DNA and 40% HBeAg testing. The proportion of HBV-susceptible patients receiving at least 1 dose of hepatitis B vaccine was 322/642 (50%). CONCLUSIONS In a large cohort of HCV-infected patients, we found a high prevalence of current or past HBV infection, but there were gaps in complete hepatitis B testing, hepatitis B-directed care, and hepatitis B vaccination. Strategies are needed to increase hepatitis B testing, linkage to care, and administration of the hepatitis B vaccine for HCV-infected persons in this healthcare system.

Abstract
This chapter describes the principles of antiviral therapy, treatment strategies, medications and recommendations for AECHB, HBV-ACLF, HBV-related liver cirrhosis, HBV-related HCC, and liver transplantation.Severe exacerbation of chronic hepatitis B is closely related to continuous HBV replication. Therefore, inhibiting HBV replication to reduce viral load may block disease progression and improve the quality of life of these patients. ETV or TDF has been recommend first-line drug for the treatment of AECHB. A hyperactive immune response due to continuous HBV replication is the main mechanism for development of severe hepatitis B. In addition to comprehensive treatment, early administration of potent nucleoside analogs can rapidly reduce HBV DNA concentration, relieve immune injury induced by HBV, and reduce liver inflammation and patient mortality. Antiviral agents have become important in the treatment of severe exacerbation of chronic hepatitis B. Long-term antiviral treatment with nucleoside analogs can delay or reverse the progress of liver cirrhosis. Virologic response, viral resistance and adverse drug reactions should be closely monitored during treatment. The treatment should be optimized for maximum effect based on each patient’s responses. Effective antiviral therapy can suppress HBV replication and reduce the incidence of HBV-related HCC. Patients with HBV-related HCC should receive individualized and optimal multidisciplinary comprehensive treatment. Anti-viral drugs with high efficacy, low resistance and low adverse drug reactions should be selected to improve the patient’s quality of life and prolong survival time. Methods to prevent HBV reinfection after liver transplantation include passive immunization (HBIG), antiviral treatment (nucleoside analogs) and active immunization (hepatitis B vaccine). Clinical trials involving sequential combination therapy with NUC and Peg-IFN have shown statistically significant decline in HBsAg levels on treatment and high rates of sustained post-treatment serologic response. Combination therapy with novel DAA and immunotherapeutic approach may hold promise to overcome both cccDNA persistence and immune escape, representing a critical step towards HBV cure.

Abstract
PURPOSE OF REVIEW This review summarizes recent data on chronic Hepatitis B virus (HBV) epidemiology, issues in special populations undergoing immunosuppressive and hepatitis C virus (HCV) direct-acting antiviral (DAA) therapy, and describes care delivery, adherence to guideline-recommended care, and barriers to access to care and high-quality care for chronic HBV. RECENT FINDINGS Chronic HBV is present in up to 1% of veterans and is more than in the general US population. HBV associated with more advanced liver disease in HCV, HIV, and delta hepatitis co-infection. Recent data on HBV reactivation show a substantial risk of reactivation with anti-CD20 antibodies, no documented cases of reactivation with anti-tumor necrosis factor (anti-TNF) therapy, and a low risk of reactivation with HCV DAA therapy. Adherence to guideline-recommended care for HBV is suboptimal for many quality indicators. SUMMARY Important studies in HBV epidemiology, long-term outcomes and care delivery practices have been conducted in the VA. Future studies should prospectively investigate how to improve guideline-recommended care for HBV.

Abstract
Hepatitis B virus may reactivate in patients with chronic hepatitis C treated with direct-acting antivirals. The aim of this study was to investigate the risk of hepatitis B virus (HBV) reactivation in HBV + hepatitis C virus (HCV)-co-infected patients with compensated liver cirrhosis treated with paritaprevir/ombitasvir/ritonavir, dasabuvir with ribavirin. We reviewed prospectively gathered data from a national cohort of 2070 hepatitis C virus patients with compensated liver cirrhosis who received reimbursed paritaprevir/ombitasvir/r, dasabuvir with ribavirin for 12 weeks from the Romanian National Health Agency during 2015-2016. Twenty-five patients in this cohort were HBs antigen positive (1.2%); 15 untreated with nucleotide analogues agreed to enter the study. These patients were followed up: ALT monthly, serology for HBV and DNA viral load at baseline, EOT and SVR at 12 weeks. Hepatitis B virus (HBV)-co-infected patients were all genotype 1b and 52% females, with a median age of 60 years (51 ÷ 74); 76% were pretreated with peginterferon + ribavirin; 72% were with severe necroinflammatory activity on FibroMax assessment; 40% presented comorbidities; and all were HBe antigen negative. Hepatitis C virus (HCV) SVR response rate was 100%. Hepatitis B virus (HBV)-DNA viral load was undetectable in 7/15 (47%) before therapy, and for the other 8 patients, it varied between below 20 and 867 IU/mL. Five patients (33%) presented virological reactivation (>2 log increase in HBV-DNA levels) during therapy. One patient presented with hepatitis associated with HBV reactivation, and two started anti-HBV therapy with entecavir. Hepatitis B virus (HBV) virological reactivation was present in 33% in our patients. Generally, HBV-DNA elevations were mild (<20 000 IU/mL); however, we report one case of hepatitis associated with HBV reactivation.

Abstract
Hepatocellular carcinoma (HCC) is a leading cause of liver-related death worldwide. Hepatitis C virus (HCV) infection is a major cause of advanced hepatic fibrosis and cirrhosis, with significantly increased risk for development of HCC. The morbidity and mortality of HCV-related HCC remains high, as rates of HCV cirrhosis continue to increase. The long-term goal of antiviral therapy for chronic HCV is to reduce complications from cirrhosis, including HCC. The advent of new direct-acting antivirals with high rates of virological clearance has revolutionized cure of HCV infection. While the development of HCC in HCV patients who achieve disease sustained virologic response is reduced, these patients remain at risk for HCC, particularly those patients with advanced fibrosis and cirrhosis. This review outlines the epidemiology of HCC in chronic HCV, various mechanisms, risk factors and pathophysiology that contribute to this disease process, screening recommendations, and the available data on the impact of new direct-acting antiviral treatment on the development on HCC.

Abstract
We investigated the long-term risk of hepatocellular carcinoma (HCC) in dual-infected hepatitis B and C patients after eradication of hepatitis C virus (HCV). A total of 164 (62% male, median age, 50.5 years) hepatitis B and C dual-infected patients who achieved HCV sustained virological response were recruited. Half the patients were HCV genotype 1 with a median viral load of 5.5 log10 IU/mL, and 22.6%had an HBV DNA level ≥ 2000 IU/mL before therapy. HCC developed in 14 patients (8.5%), with an annual incidence of 1.38% per person-year. The 3-year, 5-year, 10-year, and 15-year cumulative probabilities were 2.5%, 5.1%, 12.6%, and 22.7%, respectively. Six months after treatment, a Cox regression hazard analysis revealed platelet level (HR: 0.98, 95% CI: 0.957–0.999, P = 0.038) and AFP level (HR: 1.20, 95% CI: 1.031–1.400, P = 0.019) to be independent factors in HCC. A higher 10-year cumulative risk of HCC was detected in patients with 6-month post-treatment AFP levels > 5.0 ng/mL and platelet levels < 130 x1000/µL (54.9%), compared to patients with neither (8.6%). Although the risk of HCC is low, surveillance of HCC is encouraged in dual-infected patients after eradication of HCV. Post-treatment AFP and platelet levels predict HCC development.

Abstract
UNLABELLED The epidemiology of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections is continuously evolving. Updated data on dual HBV and HCV infection are still needed. AIMS To assess the main characteristics of patients with HBV and HCV dual infection, to compare these with those of patients infected with either HBV or HCV and, among patients with dual infection, to assess fibrosis according to HCV replication. METHODS Data of 23 patients with dual infection were compared to data from 92 age and sex-matched HBV or HCV monoinfected patients. RESULTS Patients with dual infection were more often immigrants from Africa or Asia than HCV or HBV patients (52% vs. 20% and 22%, respectively, P=0.01). Intravenous drug use was the route of transmission in 22% of patients with dual infection, which was less frequent than in HCV patients (41%) but more frequent than in HBV patients (0%). Extensive fibrosis or cirrhosis was as frequent among dual-infected patients as among those with HCV or chronic hepatitis B infection (19% vs. 29% vs. 14%, respectively, P=0.4), even when fibrosis stage was reported considering the duration of infection. In dual-infected patients, the prevalence of extensive fibrosis or cirrhosis was similar in patients with and without detectable HCV RNA (18% vs. 20%). CONCLUSIONS Patients with HBV and HCV dual infection were more often immigrants from Africa or Asia and had similar fibrosis stages than HCV or HBV monoinfected patients. In patients with dual infection, extensive fibrosis or cirrhosis was not associated with HCV replication.

Abstract
The recent introduction of direct-acting antiviral drugs (DAAs) for treatment of the hepatitis C virus (HCV) has greatly improved the management of HCV for infected patients. These viral protein inhibitors act rapidly, allowing HCV clearance and increasing the sustained virological response rates. However, hepatitis B virus (HBV) reactivation has been reported in HCV/HBV co-infected patients. Hepatitis B reactivation refers to an abrupt increase in the HBV and is well-documented in patients with previously undetected HBV DNA due to inactive or resolved HBV infection. Reactivation can occur spontaneously, but in most cases, it is triggered by various factors. Reactivation can be transient, without clinical symptoms; however, it usually causes a hepatitis flare. HBV reactivation may occur regardless of HCV genotype and type of DAA regimen. HBV screening is strongly recommended for co-infected HCV/HBV patients before initiation and during DAA therapy regardless of HBV status, HCV genotype and class of DAAs used. HBV reactivation can be prevented with pretreatment screening and prophylactic treatment when necessary. Additional data are required to evaluate the underlying mechanisms of HBV reactivation in this setting.

Abstract
BACKGROUND Despite universal vaccination, chronic hepatitis B virus (HBV) infection remains a public health concern in North America owing to immigration. We aimed to characterize the number of people with a positive result of testing for HBV surface antigen (HBsAg) in Calgary, a large urban Canadian health care region, and to assess whether recommended laboratory tests and specialist consultation were done for those identified as HBsAg-positive. METHODS Based on laboratory and Alberta Health Services administrative data, we identified all adults (age > 18 yr) with a positive HBsAg test result from Jan. 1 to Dec. 31, 2014 within the Calgary Zone. Demographic and relevant laboratory data were extracted within 6 months of a positive HBsAg test result, and referral to hepatology (2011-2014) was identified from data on referral to a centralized clinic. Parametric and nonparametric statistical methods were used for analyses. RESULTS We identified 1214 HBsAg-positive people (584 women [48.1%]; median age 44 [interquartile range (IQR) 36-55] yr). A total of 1192 people (98.2%) had alanine aminotransferase testing (median level 23 [IQR 16-34] U/L; 117 [9.8%] with elevated levels), 682 (56.2%) had testing for HBV DNA (median level 2.8 [IQR 2.1-3.8] logIU/mL), 630 (51.9%) had HBV e antigen testing (negative result in 548 [87.0%]), and 145 (11.9%) had HBV e antibody testing (positive result in 111 [76.6%]). Overall, 144 people (11.9%) received anti-HBV treatment, and 390 (32.1%) were referred to a hepatologist. INTERPRETATION Many HBsAg-positive people in Calgary did not receive the recommended laboratory assessments. The results highlight the necessity of continual public health efforts to screen for chronic HBV infection in Canada and to ensure adequate follow-up in order to reach the World Health Organization's goal of viral hepatitis elimination by 2030.

Abstract
Since the 1970s, the epidemic of hepatocellular carcinoma (HCC) has spread beyond the Eastern Asian predominance and has been increasing in Northern hemisphere, especially in the United States (US) and Western Europe. It occurs more commonly in males in the fourth and fifth decades of life. Among all cancers, HCC is one of the fastest growing causes of death in the US and poses a significant economic burden on healthcare. Chronic liver disease due to hepatitis B virus or hepatitis C virus and alcohol accounts for the majority of HCC cases. Incidence of nonalcoholic fatty liver disease has been on the risem and it has also been associated with the development of HCC. Its pathogenesis varies based on the underlying etiological factor although majority of cases develop in the setting of background cirrhosis. Carcinogenesis of HCC includes angiogenesis, chronic inflammation, and tumor macroenvironment and microenvironment. There is a significant role of both intrinsic genetic risk factors and extrinsic influences such as alcohol or viral infections that lead to the development of HCC. Understanding its etiopathogenesis helps select appropriate diagnostic tests and treatments.

Abstract
Understanding the biology of spontaneous clearance of hepatitis C virus (HCV) infection could lead to improved strategies to prevent the sequelae associated with chronic HCV infection. Chronic infections with hepatitis virus are very common in China, but the factors associated with spontaneous clearance of HCV have not been adequately studied. We evaluated the spontaneous clearance of HCV among 1918 drug users and 1526 HCV-seropositive blood donors in Guangzhou, China. Among participants who were co-infected with hepatitis B virus (HBV), 41.38% of drug users and 39.47% of blood donors had cleared their HCV infection without antiviral therapy compared to 9.41% of drug users and 16.73% of blood donors who were mono-infected with a single virus (P<.01). The proportion of subjects who had cleared their HCV infection was significantly greater in the co-infected subjects whose serum HBV DNA was greater than 2000IU/mL than those with lower levels. A multiple logistic regression analysis found female gender, IL28B rs8099917 TT genotype, HBV co-infection and blood donors (vs drug users) associated with increased spontaneous clearance of HCV infection. Although acute HCV infections are common in China, the incidence of chronic HCV may be reduced among the high prevalence of chronic HBV and IL28B genotypes associated with spontaneous clearance of HCV in Chinese populations.

Circadian clock in mammals is determined by a core oscillator in the suprachiasmatic nucleus (SCN) of the hypothalamus and synchronized peripheral clocks in other tissues. The coherent timing systems could sustain robust output of circadian rhythms in response to the entrainment controlled environmentally. Disparate approaches have discovered that clock genes and clock-controlled genes (CCGs) exist in nearly all mammalian cell types and are essential for establishing the mechanisms and complexity of internal time-keeping systems. Accumulating evidence demonstrates that the control of homeostasis and pathology in the liver involves intricate loops of transcriptional and post-translational regulation of clock genes expression. This review will focus on the recent advances with great importance concerning clock rhythms linking liver homeostasis and diseases. We particularly highlight what is currently known of the evolving insights into the mechanisms underlying circadian clock. Eventually, findings during recent years in the field might prompt new circadian-related chronotherapeutic strategies for the diagnosis and treatment of liver diseases by coupling these processes

Abstract
AIM To clarify the prevalence of occult hepatitis B virus (HBV) infection (OBI) and the association between OBI and liver disease progression, defined as development of liver cirrhosis or hepatocellular carcinoma (HCC), worsening of Child-Pugh class, or mortality in cases of chronic hepatitis C virus (HCV) infection.
METHODS This prospective cohort study enrolled 174 patients with chronic HCV infection (chronic hepatitis, n = 83; cirrhosis, n = 47; HCC, n = 44), and evaluated disease progression during a mean follow-up of 38.7 mo. OBI was defined as HBV DNA positivity in 2 or more different viral genomic regions by nested polymerase chain reaction using 4 sets of primers in the S, C, P and X open reading frame of the HBV genome.
RESULTS The overall OBI prevalence in chronic HCV patients at enrollment was 18.4%, with 16.9%, 25.5% and 13.6% in the chronic hepatitis C, liver cirrhosis and HCC groups, respectively (P = 0.845). During follow-up, 52 patients showed disease progression, which was independently associated with aspartate aminotransferase > 40 IU/L, Child-Pugh score and sustained virologic response (SVR), but not with OBI positivity. In 136 patients who were not in the SVR state during the study period, OBI positivity was associated with neither disease progression, nor HCC development.
CONCLUSION The prevalence of OBI in chronic HCV patients was 18.4%, and OBI was not associated with disease progression in South Koreans.

Abstract
BACKGROUND Rates of hospitalization due to chronic hepatitis C virus (HCV) are increasing in Canada and the United States. A large proportion of immigrants originate from countries with intermediate to high HCV prevalence but are not screened for HCV post-arrival and may therefore have increased risks of liver-related complications and hospitalization. METHODS We conducted a retrospective cohort study of reported HCV cases in Québec, Canada, from 1998 to 2007 that were linked to administrative health databases. Outcomes included all-cause and liver-related hospitalizations and in-hospital days in immigrants compared with nonimmigrants adjusted for age, sex, and comorbidities. RESULTS We identified 20 139 HCV cases; 9% (N = 1821) were immigrants. At diagnosis, immigrants were older (47.6 vs 43.2 years) and more likely to have hepatocellular carcinoma (HCC; 0.93% vs 0.31%), while nonimmigrants were 2- to 10-fold more likely to have substance use-related comorbidities. Mean time to HCV diagnosis after arrival was 9.8 years. Nonimmigrants had higher rates of all-cause hospitalization (adjusted rate ratio [95% confidence interval], 1.42 [1.35-1.47]), driven by mental illness and injury and/or poisoning. Unadjusted liver-related hospitalization rates were similar between cohorts. After adjustment, immigrant status was associated with lower rates of liver-related hospitalization (0.68 [.53-.88]). CONCLUSIONS Higher burden of all-cause hospitalization in nonimmigrants likely reflects more prevalent behavioral comorbidities. Similar liver-related hospitalization rates appear to be driven by older age in immigrants who were more likely to have HCC at diagnosis possibly reflecting delayed HCV diagnosis. These findings suggest that earlier screening and treatment in immigrants could play an important role in preventing HCV complications in this population.

Abstract
BACKGROUND Liver-related mortality varies across developed nations. AIM To assess the relative role of various risk factors in relation to liver-related mortality in an ecological study approach. METHODS Data for liver-related mortality, prevalence data for hepatitis B and C, human immunodeficiency virus (HIV), alcohol consumption per capita, Type 2 Diabetes mellitus (T2DM), overweight and obesity were extracted from peer-reviewed publications or WHO databases for different developed countries. As potential other risk-modifying factors, purchase power parity (PPP)-adjusted gross domestic product (GDP) per capita and health expenditure per capita were assessed. As an environmental 'hygiene factor', we also assessed the effect of the prevalence of Helicobacter pylori. Only countries with a PPP-adjusted GDP greater than $20 000 and valid information for at least 8 risk modifiers were included. Univariate and multivariate analyses were utilised to quantify the contribution to the variability in liver-related mortality. RESULTS The proportion of chronic liver diseases (CLD)-related mortality ranged from 0.73-2.40% [mean 1.56%, 95% CI (1.43-1.69)] of all deaths. Univariately, CLD-related mortality was significantly associated with Hepatitis B prevalence, alcohol consumption, PPP-adjusted GDP (all P < 0.05) and potentially H. pylori prevalence (P = 0.055). Other investigated factors, including hepatitis C, did not yield significance. Backward elimination suggested hepatitis B, alcohol consumption and PPP-adjusted GDP as risk factors (explaining 66.3% of the variability). CONCLUSION Hepatitis B infection, alcohol consumption and GDP, but not hepatitis C or other factors, explain most of the variance of liver-related mortality.

Abstract
BACKGROUND Approximately 15% to 35% of those with chronic hepatitis C (CHC) related cirrhosis will develop hepatocellular cancer (HCC). With this burden increasing across the globe, identification of risk factors for HCC has become imperative. Exposure to Agent Orange has been implicated as a possible risk factor for liver cancer in a study from the Republic of Korea. However, there has been no study in U.S. veterans with CHC and cirrhosis that has evaluated exposure to Agent Orange as a risk factor for HCC. We conducted a retrospective study of U.S. military veterans diagnosed with CHC and cirrhosis over a period of 14 years to evaluate potential risk factors for HCC including exposure to Agent Orange. METHODS We retrospectively reviewed 390 patients with confirmed CHC-related cirrhosis between 2000 and 2013 and identified patients with HCC. We compared demographic, laboratory, and other clinical characteristics of patients with and without HCC. RESULTS The mean age of the cohort was 51 years (SD =7.5), with the majority being male (98.5%). Seventy-nine of 390 (20.2%) patients developed HCC, diagnosed on average 8 (SD =4.8) years after diagnosis of CHC. Nearly half (49.4%) were Childs A, 40.5% were Childs B, and 10.1% were Childs C. HCC patients were more likely to be African American than non-HCC patients (40.5% vs. 25.4%, P=0.009) and to be addicted to alcohol (86.1% vs. 74.3%, P=0.027). A trend toward significance was seen in the HCC group for exposure to Agent Orange (16.5% vs. 10.0%, P=0.10) and smoking addiction (88.6% vs. 80.7%, P=0.10). Consequently, race, alcohol addiction, Agent Orange exposure, and smoking addiction were included in the multivariable logistic regression (MLR) analysis. Alcohol addiction [odds ratio (OR) =2.17; 95% confidence interval (CI), 1.07-4.43] and African American race (OR =2.07; 95% CI, 1.22-3.51) were found to be the only two definitive independent risk factors for HCC in our sample. CONCLUSIONS African American race and alcohol addiction were independent risk factors for HCC development in this U.S. veteran population. There was no significant association between exposure to Agent Orange and HCC, although larger studies are needed in the U.S. military veteran population to evaluate further this toxic herbicide from the Vietnam War era.

Abstract
Hepatitis B (HBV) and C (HCV) viruses cause many liver diseases. To move beyond statistical interaction, we aimed to assess the coordinated effect of the two viruses on mortality using mediation analyses. A prospective cohort study of 3837 residents in Taiwan examined participants seropositive for hepatitis B, of which 181 subjects (4.7 %) were co-infected by HCV and 589 died during follow-up. Mediation analyses for cause-specific mortality were performed using Cox proportional hazards model. Follow-up HBV viral load was inversely correlated with baseline HCV viral load (r(2) = -0.074; P < 0.001). For HCV serum viral load increasing from 800 to 404,000 IU/mL (minimum to median) at baseline, the effect of HCV mediated through HBV viral load decreased the all-cause mortality with a hazard ratio (HR) of 0.89 (95 % confidence interval (CI) 0.85, 0.94; P < 0.001), and the effect independent of HBV viral load had an opposite HR of 1.25 (95 % CI 0.98, 1.60; P = 0.08). The protective mediation effects of HCV viral load through HBV DNA level were observed in mortality from causes specific to liver-related diseases and liver cancer, but not in that from non-liver-related diseases. Our findings suggest a suppressive effect of HCV on mortality mediated through decreasing HBV viral load.

Abstract
Hepatitis C virus (HCV)-associated hepatocellular carcinoma (HCC) incidence in the United States is increasing, partly because of risk factors such as diabetes, fatty liver, hepatitis B virus, and human immunodeficiency virus coinfection. Achieving sustained virologic response (SVR) is the most significant factor in reducing HCV-associated HCC incidence. Improved SVR with the next generation of direct-acting antivirals brings hope for decreased HCC mortality. Nevertheless, surveillance for HCC remains important because HCC can still occur despite SVR, especially in cirrhotics. Individualized risk stratification through increased understanding of HCC pathogenesis and improved surveillance holds the promise for future reduction of HCC incidence.

Abstract
Hepatitis C infection is a common cause of cirrhosis and indication for liver transplantation in the United States. The incidence of chronic hepatitis C has been declining, but rates of cirrhosis and hepatocellular carcinoma are projected to increase. The outcome of chronic hepatitis C is variable. It is estimated that 20% to 25% will develop cirrhosis over a 25-year to 30-year period. The rate of disease progression is influenced by many host, viral, and environmental factors. Few can be modified.
