Abstract
All-oral, direct-acting antivirals can cure hepatitis C virus (HCV) in almost all infected individuals; yet, many individuals with chronic HCV are not treated, and the incidence of acute HCV is increasing in some countries, including the United States. Strains on healthcare resources during the COVID-19 pandemic negatively impacted the progress toward the World Health Organization goal to eliminate HCV by 2030, especially among persons who inject drugs (PWID). Here, we present a holistic conceptual framework termed LOTUS (Leveraging Opportunities for Treatment/User Simplicity), designed to integrate the current HCV practice landscape and invigorate HCV treatment programs in the setting of endemic COVID-19: (A) treatment as prevention (especially among PWID), (B) recognition that HCV cure may be achieved with variable adherence with evidence supporting some forgiveness for missed doses, (C) treatment of all persons with active HCV infection (viremic), regardless of acuity, (D) minimal monitoring (MinMon) during treatment, and (E) rapid test and treat (TnT). The objective of this article is to review the current literature supporting each LOTUS petal; identify remaining gaps in knowledge or data; define the remaining barriers facing healthcare providers; and review evidence-based strategies for overcoming key barriers.

Abstract
BACKGROUND Assess impact of direct-acting antivirals introduction on outcomes after liver resection for hepatocellular carcinoma. METHODS 391 patients (1991-2021) treated with resection for hepatocellular carcinoma on Hepatitis C background were divided according to receiving Hepatitis C treatment, treatment type, achievement of sustained virological response (SVR), time of resection pre- (Era 1, 1991-2011) and post-direct acting antivirals introduction (Era 2, 2012-2021). Survival was estimated with Kaplan-Meier curves, Cox regression analysis performed to identify survival predictors. RESULTS Majority of patients had single lesion (67.8%), diameter >2 cm in 60.6%, no evidence of macroscopic vascular invasion on imaging. Pathology showed vascular invasion in 69.6% of patients, 76.5% microvascular. Recurrence developed in 247 patients (63.2%). 194 patients (49.6%) achieved SVR. Overall survival at 1-, 3-, 5-years was 94.6%, 85.7%, 78.8% for patients who achieved SVR, 80.1%, 48.1%, 29.9% in those who did not (p < 0.001). 220 patients (56.3%) were in Era 1, 171 (43.7%) in Era 2. Survival at 1-, 3-, 5-years was 76.1%, 49%, 36% in Era 1, 94.5%, 82.5%, 70.3% in Era 2 (p < 0.001). SVR was an independent predictor of survival on multiple Cox Regression analysis. CONCLUSION While many aspects of HCC management have evolved, SVR following direct-acting antivirals independently improves HCC resection outcomes.

Abstract
Introduction Primary care doctors (PCDs) play an increasingly important role in the management of hepatitis C. It is essential for PCDs to have good self-efficacy in screening and treating hepatitis C to achieve good outcomes. This study aimed to determine the knowledge and attitude towards and other factors associated with self-efficacy in screening and treating hepatitis C. Methods This cross-sectional study was conducted using an online Google Form. PCDs working at primary healthcare clinics were selected via simple random sampling. The online form contained items on sociodemographic and practice characteristics and a validated questionnaire on knowledge, attitude and self-efficacy towards screening and treating hepatitis C. Data were statistically analysed. Results A total of 242 PCDs were included in the analysis. The median age was 35 years (interquartile range [IQR]=5). The majority of the PCDs were women (83.9%) and Malay (71.9%) and had a median working experience of 6 years (IQR=6). The mean self-efficacy score was 12.67 (standard deviation=3.38). The factors associated with a higher level of self-efficacy in screening and treating hepatitis C were postgraduate qualification, training within the last one year, better knowledge and attitude scores and prior experience in treating hepatitis C. Conclusion The identified factors are crucial in improving the self-efficacy among PCDs in hepatitis C care services. Policymakers are suggested to implement training programmes and encourage continuous medical education, exposure to patient management and postgraduate certification in family medicine to help PCDs in treating hepatitis C better.

Abstract
Among individuals coinfected with HCV and HIV, studies of mortality from non-hepatic causes have shown inconsistent results. The aim of this study was to investigate the contribution of HCV and HIV co-infection to mortality from hepatic and non-hepatic causes in Brazil. This retrospective cohort study included blood donors from Fundação Pró-Sangue de São Paulo (FPS) who were followed from 1994 to 2016 to compare mortality and its causes between HIV-HCV coinfected individuals versus those seronegative for all tested infections. Records from the FPS database and the Mortality Information System were linked through a probabilistic record Relationship (RL). The Hazard Ratio (HR) was estimated using Cox multiple regression models. HCV-HIV coinfected individuals compared to seronegative individuals had a higher risk of death from all causes (HR = 14.54), non-liver neoplasms (HR = 2.55), infections (HR = 10.37) and liver disease (HR = 7.0). In addition, HCV mono-infected individuals compared to seronegative individuals had a higher risk of death from all causes (HR = 2.23), liver cancer (HR = 32.21), liver disease (HR = 14.92), infection (HR = 3.22), and trauma (HR = 1.68). Individuals coinfected with HCV and HIV have increased overall mortality and death due to infections, liver diseases and non-liver neoplasms as compared to those uninfected with HCV and HIV.

Abstract
Background and Objectives: The global prevalence of chronic hepatitis C virus (HCV) infection is 0.8%, affecting around 58 million people worldwide. Treatment with DAAs reduces all-cause HCV mortality by 49-68%. This work aims to determine whether there is liver fibrosis regression (LFR) in patients who achieved Sustained Virological Response (SVR) after treatment with DAAs. Materials and Methods: An analytical, observational, single-center, and cohort study was carried out. The final sample consisted of 248 HCV-infected patients. All started treatment with DAAs between January 2015 and December 2017. Five measurements were performed to determine the fibrotic stage in patients (measured in kilopascals (kPa)) using transient elastography (FibroScan®, Echosens, The Netherlands). Results: Taking the baseline fibrotic stage as a reference, the distribution in subgroups was as follows: 77 F4 patients (31.0%); 55 F3 patients (22.2%); 53 F2 patients (21.4%); and 63 F0/F1 patients (25.4%). There were 40 patients (16.1%) with at least one HCV complication and 13 (5.2%) who developed hepatocellular carcinoma. The overall LFR rate was 77.8% (144 of 185 F2/F3/F4 patients, p = 0.01) at the end of the follow-up period. The highest mean FibroScan® values were observed in patients with: "male gender"; "metabolic syndrome"; "subtype 1a"; "NRP DAA"; "at least one HCV complication"; "death from HCV complications"; and "liver transplantation requirement". Conclusions: Treatment with DAAs achieved high rates of LFR and a decrease in mean FibroScan® values in all subgroups.

Abstract
BACKGROUND Prospective studies of the long-term outcomes of patients with hepatitis C virus (HCV) infection after treatment with interferon-based therapy (IBT) or direct-acting antivirals (DAA) are limited in many Asian countries.
AIM To elucidate the incidences of hepatocellular carcinoma (HCC) and death/transplantation based on treatment with IBT or DAA, to compare the outcomes of the sustained virologic response (SVR) to IBT and DAA, and to investigate outcome-determining factors after SVR.
METHODS This cohort included 2054 viremic patients (mean age, 57 years; 46.5% male; 27.4% with cirrhosis) prospectively enrolled at seven hospitals between 2007 and 2019. They were classified as the untreated group (n = 619), IBT group (n = 578), and DAA group (n = 857). Outcomes included the incidences of HCC and death/transplantation. The incidences of the outcomes for each group according to treatment were calculated using an exact method based on the Poisson distribution. A multivariate Cox regression analysis was performed to determine the factors associated with HCC or death/transplantation, followed by propensity score matching to confirm the results.
RESULTS During a median of 4.1 years of follow-up, HCC and death/transplantation occurred in 113 and 206 patients, respectively, in the entire cohort. Compared with the untreated group, the incidences of HCC and death/transplantation were significantly lower in the IBT group [adjusted hazard ratio (aHR) 0.47, 95%CI: 0.28-0.80 and aHR 0.28, 95%CI: 0.18-0.43, respectively] and the DAA group (aHR 0.58, 95%CI: 0.35-0.96, and aHR 0.19, 95%CI: 0.20-0.68, respectively). Among 1268 patients who attained SVR with IBT (n = 451) or DAA (n = 816), the multivariable-adjusted analysis showed no differences in the risks of HCC (HR 2.03; 95%CI: 0.76-5.43) and death/transplantation (HR 1.38; 95%CI: 0.55-3.49) between the two groups. This was confirmed by a propensity score-matching analysis. Independent factors for HCC after SVR were age, genotype 1, and the presence of cirrhosis.
CONCLUSION Treatment and achieving SVR with either IBT or DAA significantly reduced the incidences of HCC and mortality in the Asian patients with HCV infection. The risks of HCC and mortality were not significantly different regardless of whether SVR was induced by IBT or DAA.

Abstract
Background: Hepatitis C virus (HCV) has been shown to be associated with human papillomavirus (HPV)-positive head and neck cancers. However, studies regarding HPV infection and the risk of new-onset hepatocellular carcinoma (HCC) among chronic hepatitis C (CHC) patients are limited. We examined the risk of HCC in CHC patients with or without HPV infection. Methods: In total, 9905 CHC patients from 2000 to 2016 constituted the whole cohort. HPV was defined as being diagnosed after HCV. The CHC cohort with HPV (N = 1981) and age-, sex-, inception point-, comorbidity-, and medication-matched non-HPV (N = 7924) were followed up until HCC, death, or 2018. HCC patients were extracted from the Taiwan Registry for Catastrophic Illness Database. We adopted the propensity score match and inverse probability of treatment weighting (IPTW) to eliminate bias. Cox proportional hazard regression analyses were performed to calculate HCC risk. Results: After a full adjustment, HPV was not associated with HCC risk (aHR, 0.74; 95% CI, 0.58−0.96 in the main model, and aHR, 0.76; 95% CI, 0.66−0.87 in IPTW, respectively). Almost all subgroup analyses verified this finding (HRs < 1.0). Conclusions: Among CHC patients older than 18 years old, those with HPV infection were associated with a lower risk of subsequent HCC.

Abstract
Background
This study aimed to evaluate the efficacy, safety and tolerability of SOF/DCV ± RBV in a cohort of Egyptian patients with chronic hepatitis C (CHC)-induced cirrhosis with decompensation (class B7–B9).
Results
After excluding the 9 patients who withdrew, SVR12 rate according to per protocol analysis was 82.9% (92/111), non-response and relapse rates were 2.7% (3/111) for each, 4 patients died secondary to hematemesis, and 8.1% stopped therapy due to worsening of Child’s class. SVR12 rate was significantly higher among patients with higher baseline WBCs count and lower among patients with Child-Pugh class B9. All treatment intolerant patients had ascites in pre-treatment assessment (P = 0.02). There was a significant decline in the levels of hemoglobin, ALT and AST, and serum bilirubin (P < 0.001) and a significant increase in albumin level (P < 0.001) at the end of treatment when compared to their pre-treatment levels. Follow-up of the three HCC did not show evidence of tumor recurrence.
Conclusions
The SOF/DCV combination ± ribavirin is an effective and safe regimen for patients with CHC induced cirrhosis with mild decompensation. Treatment did not increase the risk of HCC recurrence.

Abstract
Viral hepatitis results in 1.4 million deaths annually. The World Health Organization (WHO) set an ambitious target to eliminate viral hepatitis by 2030, but significant challenges remain. These include inequalities in access to healthcare, reaching at risk populations and providing access to screening and effective treatment. Stigma around viral hepatitis persists and must be addressed. The WHO goal of global elimination by 2030 is a worthy aim, but remains ambitious and the coronavirus 2019 pandemic undoubtedly has set back progress. This review article will focus on hepatitis A to E, highlighting problems that have been resolved in the field over the past decade, those that remain to be resolved and suggest directions for future problem solving and research.

Abstract
AIM In this retrospective cohort study, we evaluated the significance of liver volume in the prediction of hepatocellular carcinoma (HCC) in 277 chronic hepatitis C (CHC) patients who received dynamic computed tomography (CT) during surveillance. METHODS Liver volumes were measured on portal venous phase of CT images by using ImageJ software. Liver volume index, a ratio of the standard liver volume expected by weight and height to the measured liver volume, was calculated to adjust for normal variations. The cohort was randomly divided to derivation (n = 100) and validation sets (n = 177) for the generation of a liver volume-based Cox prediction model and validation of a liver volume-based nomogram, respectively. RESULTS The liver volume index was independent of weight or height, and it predicted further development of HCC (hazard ratio [HR] 16.30, 95% CI 6.70-39.62; p < 0.001). Liver cirrhosis, gamma-glutamyl transferase, and liver volume index were independent predictors of HCC, and nomogram-based prediction score from these three parameters identified high-risk patients at the cutoff of 110 in both derivation (p < 0.001) and validation cohort (p < 0.001). CONCLUSION Liver volume-based prediction model stratifies the risk of developing HCC in CHC patients whose initial dynamic CT study gave negative results.

Abstract
BACKGROUND Aspirin use has been suggested to reduce cancer risk. However, previous studies showed inconsistent results as for the association between aspirin use and mortality in patients with hepatocellular carcinoma (HCC). The aim of the study was to evaluate the influence of aspirin use on clinical outcomes of patients with HCC in a meta-analysis. MATERIALS Studies were obtained via systematic search of PubMed, Cochrane's Library, and Embase databases. A random-effect model, which incorporated the potential heterogeneity, was used to pool the results. RESULTS Six retrospective cohort studies including 18,855 HCC patients that underwent liver resection or transarterial chemoembolization were included. Pooled results showed that compared to the non-users, aspirin users of HCC had significantly reduced risk of HCC recurrence (risk ratio [RR]: 0.74, 95% confidence interval [CI]: 0.59-0.93, p = 0.01; I2 = 34%) and all-cause mortality (RR: 0.59, 95% CI: 0.47-0.73, p < 0.001; I2 = 0%) after controlling of potential confounding factors. In addition, pooled results showed that aspirin use was not associated with a significantly increased risk of major bleeding events (RR: 1.42, 95% CI: 0.81-2.51, p = 0.22; I2 = 29%) in patients with HCC. CONCLUSIONS Evidence from retrospective studies suggests that aspirin use is associated with reduced recurrence and all-cause mortality of HCC. These results should be validated in prospective cohort studies and randomized controlled trials.

Abstract
OBJECTIVES HIV-coinfected patients experience higher incidences of non-liver-related cancers than HCV-monoinfected patients. Chronic inflammation, immunosuppression, but also higher tobacco or alcohol consumption and metabolic dysregulation could explain this higher risk. We aimed to estimate the direct, indirect and total effects of HIV coinfection on the risk of non-liver-related cancers in HCV participants treated with direct-acting antivirals (DAAs). METHODS Up to four HCV-monoinfected participants from the ANRS CO22 HEPATHER cohort were matched by age and sex to HIV/HCV-coinfected participants from the ANRS CO13 HEPAVIH cohort. Participants were followed from DAA initiation until the occurrence of a non-liver-related cancer. Counterfactual mediation analysis was carried out to estimate the direct (chronic inflammation and immunosuppression), indirect (tobacco and alcohol consumption and metabolic syndrome) and total effect of HIV coinfection on the risk of non-liver-related cancers. RESULTS 548 HIV/HCV-coinfected and 2016 monoinfected participants were included. Overall, HIV coinfection was associated with a 3.7-fold [95% confidence interval (CI): 1.7-7.0] higher risk of non-liver-related cancers in HCV participants. This increased risk was explained by significant direct effect [hazard ratio (HR) = 3.4, 95% CI: 1.7-6.6] but not indirect effect (HR = 1.1, 95% CI: 0.8-1.5) of HIV coinfection. CONCLUSIONS In HCV participants treated with DAAs, the direct effect of HIV coinfection, reflecting chronic inflammation and immunosuppression, was associated with a 3.7-fold higher risk of non-liver-related cancer. By contrast, the indirect effect of HIV coinfection, reflecting higher tobacco and alcohol consumption and metabolic dysregulation, was not significantly associated with the risk of non-liver-related cancers.

Abstract
Background The current antiviral treatments available for hepatitis C virus (HCV) infection decrease the risk of hepatocellular carcinoma (HCC). Hence, patients with HCV infection who have not received antiviral treatment and have developed HCC may be those who missed timely antiviral treatment for HCV. However, the proportion of patients who missed timely antiviral treatment and its implications are largely unexplored. Methods A nationwide retrospective cohort of 4,592 newly diagnosed HCV-related HCC patients (2013–2017) was identified from the Korean National Health Insurance Service database. Prior antiviral treatment for HCV was defined as a history of at least one HCV-specific antiviral treatment before HCC diagnosis. The outcome was all-cause mortality. Results Prior antiviral treatment for HCV was identified in 802 (17.4%) patients, and 16%, 16%, 17%, 19%, and 19% of patients received antiviral treatment in the years 2013, 2014, 2015, 2016, and 2017, respectively (P = 0.21). During 8,085 person-years of follow-up (median, 1.4; maximum, 5.3 years of follow-up), 1,970 patients died. Mortality rates were lower in patients with prior antiviral treatment (15 deaths/100 person-years) than in those without prior antiviral treatment (27 deaths/100 person-years). The adjusted hazard ratio (95% confidence interval) for all-cause mortality on comparing patients who did and did not receive prior antiviral treatment was 0.68 (0.59, 0.79). Conclusion Timely antiviral treatment for HCV was suboptimal at the population level. Prior antiviral treatment for HCV reduced mortality rate in HCV-related HCC patients. Intensive HCV control strategies are needed to reduce the number of patients with HCV infection who miss timely HCV treatment.

Abstract
OBJECTIVES Sustained virological response (SVR) decreases the risk of hepatitis C virus (HCV)-related events. Nevertheless, a substantial risk of events persists. We estimated incidences and identified factors associated with severe clinical events after SVR following treatment with a direct-acting antiviral (DAA) in HIV/HCV-coinfected patients. METHODS Participants from the ANRS CO13 HEPAVIH were included if they reached SVR. Incidence rates of overall mortality, liver-related events, AIDS-defining events, ischaemic events and non-liver non-AIDS-defining cancers (NLNA) were estimated. Factors associated with the risk of those events were identified using Poisson models adjusted on age at SVR and sex. RESULTS In all, 775 participants were included. Incidence rates (95% confidence interval) of liver-related events, overall mortality, AIDS-defining events, ischaemic events and NLNA cancers per 1000 person-years were 5.9 (3.3-10.3), 22.2 (16.8-29.5), 0.6 (0.1-4.5), 7.3 (4.4-12.2) and 13.7 (9.4-20.0), respectively. For all events, incidence rates were higher in cirrhotic than in non-cirrhotic participants. Cirrhosis, liver stiffness and CD4 count were associated with liver-related events. Factors associated with overall mortality were age, cirrhosis, liver stiffness and gamma-glutamyl transferase (GGT). For ischaemic events and NLNA cancers, associated factors were total cholesterol and CD4 count, respectively. CONCLUSIONS After SVR following a DAA treatment, liver-related and AIDS-defining events were observed less frequently than NLNA cancers. Severity of liver disease was associated with the risk of liver-related events and of overall mortality but not with ischaemic events and NLNA cancers. Factors reflecting HIV infection were associated with NLNA cancers and liver-related events.

Abstract
The long-term effects of direct-acting antiviral therapies (DAAs) for chronic hepatitis C (CHC) remain uncertain. The objective of this systematic review and meta-analysis was to assess the impact of DAAs on CHC progression and mortality. We searched Ovid MEDLINE, Ovid EMBASE and PubMed databases (January 2011 to March 2020) for studies that compared the efficacy of DAAs to a non-DAA control in patients with CHC. Main outcomes were the adjusted hazard ratios (HRs) for mortality, liver decompensation, HCC occurrence and recurrence. Pooled estimates of HRs were determined using random-effects meta-analyses with inverse variance weighting, with sensitivity analyses and meta-regression to explore the effects of clinical factors. We identified 39 articles for the primary analysis. Compared with unexposed individuals, patients treated with DAA had a reduced risk of death (HR; CI = 0.44; 0.38-0.52), decompensation (HR; CI = 0.54; 0.38- 0.76) and HCC occurrence (HR; CI = 0.72; 0.61- 0.86). The protective effect of DAA on HCC recurrence was less clear (HR; CI = 0.72; 0.44-1.16). Sustained virologic response (SVR) attainment was a significant predictor of reduced mortality (HR; CI = 0.33; 0.23-0.46), decompensation (HR; CI = 0.11; 0.05-0.24), HCC occurrence (HR; CI = 0.31; 0.27-0.37) and HCC recurrence (HR; CI = 0.32; 0.20-0.51). Meta-regression showed no evidence of effect modification by patient age, sex, presence of cirrhosis or length of follow-up. In conclusion, our findings show protective effects of DAA treatment and DAA-related SVR on CHC progression and mortality.

Abstract
Elimination of chronic hepatitis C (HCV) will require scaling up treatment, including possible HCV treatment by primary care providers. The District of Columbia (DC) has a substantial population living with untreated hepatitis C, and treatment expansion would benefit the resident population. The aim of this study was to assess the knowledge, attitudes, and behaviors of primary care providers and specialists related to hepatitis C screening and treatment. We conducted a prospective, online survey of physicians and nurse practitioners (n = 153) in DC on their knowledge, attitudes, and behaviors related to hepatitis C screening and treatment, as well as referral patterns, interest in learning, and preferred learning modalities. We compared responses by provider type. Key findings indicated that HCV screening and treatment knowledge was higher among specialty physicians as compared to primary care providers. The most common reported facilitators of HCV screening included a prompt in the electronic medical record (63%), patient education (57%), and support staff (41%). While 71% reported that HCV treatment was important in the community they serve, only 26% indicated that access to HCV specialist expertise and consultation was a major area of need. Additionally, 59% reported that they refer all HCV patients to specialists for treatment. Primary care providers in DC had moderate interest in learning how to treat chronic hepatitis C, but they need additional training. Patients are typically referred to gastroenterology, infectious diseases, and hepatology specialists who may have limited capacity to expand treatment.

Abstract
Background: Association between statin use and prognosis in patients with hepatocellular carcinoma (HCC) remains unknown. We performed a meta-analysis of follow-up studies to systematically evaluate the influence of statin use on clinical outcome in HCC patients. Methods: Studies were obtained via systematic search of PubMed, Cochrane’s Library, and Embase databases. A randomized-effect model was used to pool the results. Subgroup analyses were performed to evaluate the influence of study characteristics on the association. Results: Nine retrospective cohort studies were included. Overall, statin use was associated with a reduced all-cause mortality in HCC patients (risk ratio [RR]: 0.81, 95% CI: 0.74–0.88, P < 0.001; I2 = 63%). Subgroup analyses showed similar results for patients with stage I-III HCC (RR: 0.83, 0.79, and 0.90 respectively, P all < 0.01) and patients after palliative therapy for HCC (RR: 0.80, P < 0.001), but not for patents with stage IV HCC (RR: 0.91, P = 0.28) or those after curative therapy (RR: 0.92, P = 0.20). However, the different between subgroups were not significant (both P > 0.05). Moreover, statin use was associated with reduced HCC-related mortality (RR: 0.78, P = 0.001) in overall patient population and HCC recurrence in patients after curative therapies (RR: 0.55, P < 0.001). Conclusions: Satin use is associated with reduced mortality and recurrence of HCC. These results should be validated in prospective cohort studies and randomized controlled trials.

Abstract
BACKGROUND & AIMS Direct-acting antivirals (DAA) lead to high sustained virological response (SVR) rates and decrease the risk of disease progression. We compared SVR rates and all-cause, liver- and non-liver-related deaths, liver-related events, and non-liver-related cancers in HIV/HCV-coinfected and HCV-monoinfected participants from 2 French cohort studies after initiation of DAA treatment. METHODS Up to 4 HCV-monoinfected participants from the ANRS CO22 HEPATHER cohort were matched by age and sex to each HIV/HCV-coinfected patient from the ANRS CO13 HEPAVIH cohort; both are nationwide, prospective, multicentre, and observational. Participants were initiated on DAAs between March 2014 and December 2017. Cox proportional hazards models adjusted by age, sex, duration since HCV diagnosis, HCV transmission routes, HCV genotypes, cirrhosis, tobacco, alcohol consumption, and SVR (time dependent) were used. RESULTS A total of 592 HIV/HCV-coinfected and 2,049 HCV-monoinfected participants were included; median age was 53.3 years (inter-quartile range: 49.6-56.9) and 52.9 years (49.6; 56.7), 1,498 (73.1%) and 436 (73.6%) were men, and 159 (28.8%) and 793 (41.2%) had cirrhosis, respectively. SVR was observed in 92.9% and 94.6%, respectively. HIV coinfection was associated with higher risk of all-cause death (hazard ratio [HR] 1.93; 95% CI 1.01-3.69), non-liver-related death (HR 2.84; 95% CI 1.27-6.36), and non-liver-related cancer (HR 3.26; 95% CI 1.50-7.08), but not with liver-related-death (HR 1.04; 95% CI 0.34-3.15) or liver-related events (HR 0.66; 95% CI 0.31-1.44). CONCLUSIONS After DAA treatment, HIV-coinfected individuals had similar SVR rates and risk of liver-related deaths and events compared with HCV-monoinfected individuals, but had a higher risk of all-cause and non-liver-related deaths and non-liver-related cancers. LAY SUMMARY We compared the risk of several clinical events in participants infected by human immunodeficiency virus and hepatitis C virus with those infected with hepatitis C virus alone, matched on age and sex, after treatment with contemporary direct-acting antivirals. We found a higher risk of all-cause deaths, non-liver-related deaths, and non-liver-related cancers in participants coinfected with the human immunodeficiency virus and hepatitis C virus, and no differences for the risk of liver-related deaths or events.

Abstract
Around 71 million people are living with chronic hepatitis C virus (HCV) infection, with approximately 14% residing in sub-Saharan Africa. Direct-acting antiviral (DAA) therapies offer clear benefits for liver-related morbidity and mortality, and data from high-income settings suggest that DAA treatments also provide significant benefits in terms of health-related quality of life (HRQL). In this study, we assessed the effect of DAA treatment on HRQL for individuals treated for HCV in a clinical trial in Rwanda. We assessed the HRQL of participants using an 83-question composite survey at Day 0 ('baseline') and Week 24 ('endpoint'). Data were analysed in R. A total of 296 participants were included in this analysis. Their ages ranged from 19 to 90, and 184 (62.2%) were female. There were significant improvements from baseline to endpoint median scores for all physical and mental quality of life sub-scales. Additionally, a reduction-before and after treatment-in the proportion of those classified as depressed and needing social support was statistically significant (both P < .001). Economic productivity increased after treatment (P < .001), and households classified as food secure increased from baseline to endpoint (P < .001). These results demonstrate that Rwandans with chronic HCV infection experience both clinical and HRQL benefits, including household-level benefits like substantial gains in workforce stability, economic productivity, and poverty alleviation, from DAA treatment. A stronger demonstration of accurate and broader household-level benefits achieved through treatment of HCV with DAAs will help financing and investment for HCV in resource-constrained settings become an urgent priority.

Abstract
Hepatitis C virus (HCV) infection is a major cause of chronic liver disease, with approximately 71 million chronically infected individuals worldwide. Clinical care for patients with HCV-related liver disease has advanced considerably thanks to an enhanced understanding of the pathophysiology of the disease, as well as developments in diagnostic procedures and improvements in therapy and prevention. These therapies make it possible to eliminate hepatitis C as a major public health threat, as per the World Health Organization target, although the timeline and feasibility vary from region to region. These European Association for the Study of the Liver recommendations on treatment of hepatitis C describe the optimal management of patients with recently acquired and chronic HCV infections in 2020 and onwards.

Abstract
BACKGROUND Although secretory clusterin (sCLU) plays a crucial role in Hepatocellular Carcinoma (HCC) cells proliferation, Multiple Drug Resistance (MDR), metastasis and so on, its targeted effects and exact mechanism are still unknown. This review summarizes some new progress in sCLU as a molecular-targeted therapy in the treatment of HCC. METHODS A systematic review of the published English-language literature about sCLU and HCC has been performed using the PubMed and bibliographic databases. Some valuable studies on sCLU in HCC progression were searched for relevant articles with the keywords: HCC, diagnosis, MDR, as molecular-targeted in treatment, and so on. RESULTS The incidence of the positive rate of sCLU was significantly higher in HCC tissues as compared to the surrounding tissues at mRNA or protein level, gradually increasing with tumor-nodemetastasis staging (P<0.05). Also, the abnormal level of sCLU was related to poor differentiation degree, and considered as a useful marker for HCC diagnosis or independent prognosis for patients. Hepatic sCLU could be silenced at mRNA level by specific sCLU-shRNA or by OGX-011 to inhibit cancer cell proliferation with an increase in apoptosis, cell cycle arrest, reversal MDR, alteration of cell migration or invasion behaviors, and a decrease in GSK-3β or AKT phosphorylation in vitro, as well as significant suppression of the xenograft growth by down-regulating β-catenin, p-GSK3β, and cyclinD1 expression in vivo. CONCLUSION Abnormal hepatic sCLU expression should not only be a new diagnostic biomarker but also a novel promising target for inhibiting HCC growth.

Abstract
BACKGROUND The aim of this study was to assess the impact of HIV infection on the risk of developing hepatocellular carcinoma (HCC) in HCV-infected patients who achieve sustained virological response (SVR) with direct-acting antiviral (DAA). METHODS Multisite prospective cohort study, where HCV-monoinfected patients and HIV/HCV-coinfected individuals were included if they met: 1) SVR with DAA-based combination; 2) Liver stiffness (LS) ≥9.5 kPa previous to treatment; 3) LS measurement at the SVR time-point. The main endpoint was the occurrence of HCC. Propensity score (PS) was calculated to address potential confounders due to unbalanced distribution of baseline characteristics of HIV/HCV-coinfected and HCV-monoinfected patients. RESULTS 1035 HCV-infected patients were included, 667 (64%) coinfected with HIV. After a median (Q1-Q3) follow-up time of 43 (31-49) months, 19 (1.8%) patients developed HCC [11 (3.0%) HCV-monoinfected, 8(1.2%) HIV/HCV-coinfected individuals; p=0.013]. In the multivariable analysis, HIV co-infection was associated with a lower adjusted risk of developing HCC [sHR=0.27, 95% IC (0.08-0.90); p=0.034]. Predictors of HCC emergence were: HCV genotype 3 [sHR=7.9 (2.5-24.9); p<0.001], MELD score at SVR>10 [sHR=1.37 (1.01-1.86); p=0.043] and LS value at SVR [sHR=1.03 (1.01-1.06) for 1 kPa increase; p=0.011]. Using inverse probability weighting method on the PS, HIV-infected patients had a lower risk of HCC [powered HR=0.33 (0.11-0.85)]. CONCLUSIONS Among HCV-infected patients with advanced fibrosis, who achieve SVR with DAA, HIV-coinfection seems to be associated with a lower risk of HCC occurrence. The underlying causes for this finding need to be investigated.

Abstract
Background & Aims Chronic HCV infection is an important cause of hepatocellular carcinoma (HCC) and liver failure in the US but limited data are available in China. We compared the incidence of clinical outcomes among adults with chronic HCV infection in the US and China and examined factors associated with outcomes. Methods A parallel prospective study of 2 cohorts of patients with HCV RNA+ recruited in 1 site in the US (UMHS) and 3 sites (PUHSC) in China between September 2011 and July 2015 was carried out. Composite liver outcomes (liver-related deaths, HCC, liver transplantation or liver decompensation), were analysed using competing-risk Cox proportional hazards model to determine incidence and associated factors. Results A total of 795 UMHS and 854 PUHSC patients were followed for a median of 3.06 and 3.99 years, respectively. At enrolment, a significantly higher percentage of UMHS patients had cirrhosis (45.4% vs. 16.2%). The 5-year cumulative incidence of composite liver outcomes was significantly higher in UMHS than in PUHSC patients (25.3% vs. 6.6%, p <0.0001). Stratification by stage of liver disease at enrolment showed this difference persisted only in the subgroup without cirrhosis due to higher aspartate aminotransferase to platelet ratio index (APRI) in the UMHS cohort. A total of 493 UMHS and 502 PUHSC patients received HCV treatment, and sustained virologic response (SVR) was achieved in 88.0% UMHS and 86.8% PUHSC treated-patients. SVR as time-dependent variable was associated with 80% lower risk of composite liver outcomes among patients with decompensated cirrhosis but not the overall cohorts. Conclusions When accounting for disease severity at entry, the incidence of composite liver outcomes was similar in patients with HCV in the US and China. Achievement of SVR had the greatest short-term impact on patients with decompensated cirrhosis. Lay summary Patients with chronic hepatitis C virus infection were recruited from centres in the United States and China. During follow-up, a higher percentage of the American patients had clinical outcomes: liver failure, liver cancer, liver transplant or liver-related deaths than the Chinese patients, mainly because more American patients had cirrhosis at enrolment. Older age and more advanced liver disease were associated with higher incidence of outcomes overall and viral clearance after hepatitis C treatment was associated with a lower incidence of outcomes in patients with advanced cirrhosis. Our findings highlight the importance of improving diagnosis and treatment of hepatitis C before advanced liver disease develops. The incidence of clinical outcomes in US and Chinese patients with chronic HCV infection was compared. Outcome rates were higher in the US cohort, in which cirrhosis was more common. SVR rates were similar in the 2 cohorts. SVR decreased the incidence of clinical outcomes in patients with decompensated cirrhosis over a median 3-year follow-up.

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
Background Statin may confer anticancer effect. However, the association between statin and risk of hepatocellular carcinoma (HCC) in patients with hepatitis B virus (HBV) or hepatitis C (HCV) virus infection remains inconsistent according to results of previous studies. A meta-analysis was performed to summarize current evidence. Methods Related follow-up studies were obtained by systematic search of PubMed, Cochrane’s Library, and Embase databases. A random-effect model was used to for the meta-analysis. Stratified analyses were performed to evaluate the influences of study characteristics on the outcome. Results Thirteen studies with 519,707 patients were included. Statin use was associated with reduced risk of HCC in these patients (risk ratio [RR]: 0.54, 95% CI: 0.44 to 0.66, p < 0.001; I2 = 86%). Stratified analyses showed that the association between statin use and reduced HCC risk was consistent in patients with HBV or HCV infection, in elder (≥ 50 years) or younger (< 50 years) patients, in males or females, in diabetic or non-diabetic, and in those with or without cirrhosis (all p < 0.05). Moreover, lipophilic statins was associated with a reduced HCC risk (RR: 0.52, p < 0.001), but not for hydrophilic statins (RR: 0.89, p = 0.21). The association was more remarkable in patients with highest statin accumulative dose compared to those with lowest accumulative dose (p = 0.002). Conclusions Satin use was independently associated with a reduced risk of HCC in patients with HBV or HCV infection.

Abstract
Objective The prevalence of hepatitis C virus (HCV) infection is typically evaluated based on the current rate of positivity of anti-HCV antibody; however, HCV RNA positivity is considered the main criterion for antiviral treatment of HCV infection in the clinical setting. In this study, we evaluated the prevalence of HCV infection based on anti-HCV and HCV RNA detection in the population of Liaoning Province, and investigated the correlation between serum HCV RNA positivity and anti-HCV levels. Methods A total of 192,202 patients who underwent serum anti-HCV examination at Shengjing Hospital in 2018 were enrolled in the study. Anti-HCV production was tested using a chemiluminescence assay, and serum HCV RNA detection was performed with Roche COBAS TaqMan (CTM) Analyzer. Results The prevalence of anti-HCV was 1.21 and 0.93% among male and female patients in Liaoning Province, respectively. The positive rates of anti-HCV and serum anti-HCV levels were both age-related, in which patients over 40 years of age had a significantly higher anti-HCV positive rate than those younger than 40 years. Among the anti-HCV-positive patients, the average HCV RNA positive rate was 51.66 and 35.93% in males and females, respectively. Spearman rank analysis showed a significantly positive correlation between serum HCV RNA positivity and the level of anti-HCV. The best cut-off value using serum anti-HCV levels to predict the positivity of HCV RNA was determined to be 9.19 signal-to-cut-off ratio (s/co) in males and 10.18 s/co in females. Conclusion The prevalence of anti-HCV in the general population of Liaoning Province was around 1.04%, which was higher than that previously reported from a national survey of HCV infection in China. Approximately 42.9% of the anti-HCV-positive patients also tested positive for HCV RNA. However, the positive correlation between the serum anti-HCV and HCV RNA levels suggests that the positivity of serum HCV RNA can be predicted according to the anti-HCV level in anti-HCV-positive patients, which can improve screening and facilitate timely intervention to prevent the spread of infection.

Abstract
IMPORTANCE A 2013 review for the US Preventive Services Task Force (USPSTF) of hepatitis C virus (HCV) screening found interferon-based antiviral therapy associated with increased likelihood of sustained virologic response (SVR) and an association between achieving an SVR and improved clinical outcomes. New direct-acting antiviral (DAA) regimens are available. OBJECTIVE To update the 2013 review on HCV screening to inform the USPSTF. DATA SOURCES Ovid MEDLINE, the Cochrane Central Register of Controlled Trials, and the Cochrane Database of Systematic Reviews through February 2019, with surveillance through September 2019. STUDY SELECTION Randomized clinical trials (RCTs) and nonrandomized treatment studies of HCV screening and DAA therapy; cohort studies on screening, antiviral therapy, and the association between an SVR after antiviral therapy and clinical outcomes. DATA EXTRACTION AND SYNTHESIS One investigator abstracted data; a second checked accuracy. Two investigators independently rated study quality. MAIN OUTCOMES AND MEASURES Mortality, morbidity, quality of life, screening and treatment harms, and screening diagnostic yield. RESULTS Eight RCTs of DAA therapy vs placebo or an outdated antiviral regimen, 48 other treatment studies, and 33 cohort studies, with a total of 179 230 participants, were included. No study evaluated effects of HCV screening vs no screening. One new study since the 2013 review (n = 5917) found similar diagnostic yield of risk-based screening (sensitivity, 82%; number needed to screen to identify 1 HCV case, 15) and birth cohort screening (sensitivity, 76%; number needed to screen, 29), assuming perfect implementation. Ten open-label studies (n = 3292) reported small improvements in some quality-of-life and functional outcomes (eg, less than 3 points on the 0 to 100 36-Item Short Form Health Survey physical and mental component summary scales) after DAA treatment compared with before treatment. Two cohort studies (n = 24 686) found inconsistent associations of antiviral therapy vs no therapy with risk of hepatocellular carcinoma. Forty-nine treatment studies (n = 10 181) found DAA regimens associated with pooled SVR rates greater than 95% across genotypes, and low short-term rates of serious adverse events (1.9%) and withdrawal due to adverse events (0.4%). An SVR after antiviral therapy was associated with decreased adjusted risk of all-cause mortality (13 studies, n = 36 986; pooled hazard ratio [HR], 0.40 [95% CI, 0.28-0.56) and hepatocellular carcinoma (20 studies, n = 84 491; pooled HR, 0.29 [95% CI, 0.23 to 0.38]) vs no SVR. CONCLUSIONS AND RELEVANCE Direct evidence on the effects of HCV screening on clinical outcomes remains unavailable, but DAA regimens were associated with SVR rates greater than 5% and few short-term harms relative to older antiviral therapies. An SVR after antiviral therapy was associated with improved clinical outcomes compared with no SVR.

Abstract
Hepatocellular carcinoma (HCC) is one of the major causes of morbidity, mortality, and healthcare expenditure in patients with chronic liver disease in India. The Indian National Association for Study of the Liver (INASL) had published its first guidelines on diagnosis and management of HCC (The Puri Recommendations) in 2014, and these guidelines were very well received by the healthcare community involved in diagnosis and management of HCC in India and neighboring countries. However, since 2014, many new developments have taken place in the field of HCC diagnosis and management, hence INASL endeavored to update its 2014 consensus guidelines. A new Task Force on HCC was constituted that reviewed the previous guidelines as well as the recent developments in various aspects of HCC that needed to be incorporated in the new guidelines. A 2-day round table discussion was held on 5th and 6th May 2018 at Puri, Odisha, to discuss, debate, and finalize the revised consensus statements. Each statement of the guideline was graded according to the Grading of Recommendations Assessment Development and Evaluation system with minor modifications. We present here the 2019 Update of INASL Consensus on Prevention, Diagnosis, and Management of Hepatocellular Carcinoma in India: The Puri-2 Recommendations.

Abstract
Direct-acting antivirals (DAAs) are modern treatments for chronic hepatitis C infection, but majority of available evidence on its treatment effect covers genotypes 1 to 4. Therefore, the efficacy and safety of DAAs for genotypes 5 and 6 need to be analysed. Studies were identified from Medline, Scopus, and CENTRAL and a Chinese database CNKI, from inception until Dec 4, 2018. Clinical trials were included if they enrolled patients with genotypes 5 and/or 6 infection, any type of second-generation DAAs was studied, and sustained virological response was assessed at the 12th week after treatment (SVR12) as outcome measure. Meta-analysis using metaprop statistical program was applied for pooling proportions if data were sufficient (i.e., at least 2 studies). Thirteen studies were included in the analysis. Four studies assessed the efficacy of four DAA regimens in genotype 5 patients, which were mainly sofosbuvir (SOF) plus pegylated-interferon/ribavirin (PR) or other DAAs, with SVR12 ranging from 94.4% to 100%. Twelve studies assessed the efficacy of seven DAA regimens among genotype 6 patients, but only two DAA regimens (i.e., SOF + PR and SOF/ledipasvir) had sufficient data for pooling. The pooled SVR12 rates (95% CI) were 99.6% (92.2 to 100) for SOF + PR and 99.2% (96.5 to 100) for SOF/ledipasvir. No treatment-related serious adverse event was reported, while the nonserious adverse events were comparable to other genotypes. In conclusion, DAAs are effective and may be safe for the treatment of chronic hepatitis C genotypes 5 and 6. However, our evidence is based on noncomparative studies; hence, further larger-scale randomized controlled trials in these genotypes are still required.

Abstract
BACKGROUND The long-term data with direct acting antiviral agents were rare. This study investigated the durability of a sustained virologic response (SVR) and the improvement of fibrosis after daclatasvir and asunaprevir (DCV/ASV) treatment in genotype 1b (GT1b) hepatitis C virus (HCV)-infected patients. METHODS A total of 288 HCV GT1b patients without baseline non-structural 5A (NS5A) resistance-associated substitution (RAS) treated with DCV/ASV were enrolled. Virologic response was measured at 12 weeks and 1 year after treatment completion. In cirrhotic patients, liver function, aspartate transaminase to platelet ratio index (APRI), FIB-4 index, fibrosis index (FI), and liver stiffness measurement (LSM) at baseline and 1 year after treatment completion were evaluated. RESULTS SVR12 was obtained in 278 patients (96.5%). Six patients who checked NS5A RAS after treatment failure were RAS positive. Only one patient showed no durability of SVR. In cirrhotic patients who achieved SVR12 (n = 59), the changes of albumin (3.8 [2.2-4.7] to 4.3 [2.4-4.9] g/dL; P < 0.001), platelet count (99 [40-329] to 118 [40-399] × 10³/mm³; P < 0.001), APRI (1.8 [0.1-14.8] to 0.6 [0.1-4.8]; P < 0.001), FIB-4 index (5.45 [0.6-32.8] to 3.3 [0.4-12.2]; P < 0.001), FI (5.5 [0.6-32.8] to 3.3 [0.4-12.2]; P < 0.001), and LSM (17.2 [5.3-48.0] to 11.2 [3.7-28.1] kPa; P = 0.001) between baseline and 1 year after treatment completion were observed. CONCLUSION DCV/ASV treatment for HCV GT1b infected patients without RAS achieved high SVR rates and showed durable SVR. Cirrhotic patients who achieved SVR12 showed the improvement of liver function and fibrosis markers.

Abstract
It has been proven that hepatitis C virus (HCV) eradication after interferon-based treatment can reduce the risk of hepatocarcinogenesis. However, there were some arguments about whether the treatment of direct-acting antivirals (DAAs) boosts the development of hepatocellular carcinoma (HCC). We systematically review this crucial topic by combining all the relevant articles to calculate the pooled HCC density after DAA treatment. Studies reporting the recurrence or occurrence in chronic hepatitis C patients who received DAA regimen were selected from three retrieval library screening. Data on baseline and outcomes were extracted independently by three observers. Primary outcomes were incidence density of HCC. Pooled estimates of HCC occurrence and recurrence rate per 100 person-years (py) were undertaken by random-effects meta-analysis. Sixteen studies with 61334 patients, embracing 20 cohorts, were enrolled in this study and divided into two groups (HCC occurrence and HCC recurrence). In the pooled analysis, HCC developed at a rate of 3.5/100 py [95% confidence interval (CI): 2.4, 5.3] among patients without a history of HCC compared with 17.4/100 py (95% CI: 7.8, 39.0) among patients existed. Furthermore, HCC occurrence rate following DAA-induced sustained virological response (SVR) was 2.1/100 py (95% CI: 1.4, 3.4); however, the rate in patients without SVR was 9.1/100 py (95% CI: 5.4, 15.3). HCV cured after DAA therapy could induce a reduction of 78% in the risk of HCC occurrence compared with non-responders. There is no strong evidence for an increased risk of HCC occurrence or recurrence in patients treated by DAA. There was a significant decline in the incidence of HCC occurrence after SVR.

Abstract
OBJECTIVE To assess the impact of HIV coinfection on the risk of developing liver-related complications in HCV-infected patients with advanced fibrosis treated with direct-acting antivirals (DAA) after sustained virological response (SVR). DESIGN Prospective cohort study. SETTING Multicenter. SUBJECTS Patients from the GEHEP and HEPAVIR cohorts were selected if they fulfilled the following criteria: treatment against HCV with all oral DAA combination; SVR achievement, defined as undetectable plasma HCV RNA 12 weeks after the end of therapy; pretreatment liver stiffness equal to or higher than 9.5 kPa; liver stiffness measurement at the time of SVR. MAIN OUTCOME MEASURE(S) The primary variable was the time until the development of a liver complication or requiring liver transplant. RESULTS Seven hundred and seventeen patients were included and 507 (71%) were coinfected with HIV. After a median follow-up time of 21 (14-25) months, 15 (2.1%) patients developed a liver complication and/or underwent a liver transplant and 15 (2.0%) died. The probability of remaining free of hepatic complications or transplant at 1 and 2 was, respectively, 99 and 96% in HCV-monoinfected patients and 99 and 98% in coinfected patients (P = 0.648). In a multivariate analysis, in which nonliver-related death was considered as a competing event, HIV coinfection was not associated with the appearance of hepatic complications or requiring liver transplant [hazard ratio = 0.24; 95% CI (0.03-1.93), P = 0.181]. Having presented hepatic decompensation prior to SVR [hazard ratio = 29.06; 95% CI (3.91-216.16), P < 0.001] and the value of liver stiffness at the SVR time-point (hazard ratio = 1.12; 95% CI (1.07-1.18), P < 0.001] were associated with a higher probability of development of liver events. CONCLUSION HIV coinfection is not associated with a higher probability of developing liver complications in HCV-infected patients with advanced fibrosis, who achieved SVR with interferon-free regimens.

Abstract
Background Steatosis contributes to liver fibrosis in hepatitis C virus (HCV) and human immunodeficiency virus (HIV)/HCV coinfection. Liver biopsy (LB) is the reference standard for grading steatosis and staging fibrosis, yet recent advances in noninvasive modalities have largely supplanted LB, which may limit recognition of steatosis. We evaluated steatosis rates by LB and transient elastography (TE) with controlled attenuation parameter (CAP) among HCV-infected and HIV/HCV-coinfected patients in a US clinic. Methods Patients with chronic HCV infection during pretreatment evaluation by LB (n = 421; December 2001 through May 2014) and TE with CAP (n = 1157; May 2016 through May 2017) were included. Fibrosis and steatosis rates by LB and TE with CAP were stratified by HCV versus HIV/HCV coinfection status. Results Steatosis was not reported in 26.1% of LBs. Moderate to severe steatosis (grade ≥S2) was detected more often with CAP than with LB (in 24.0% vs 11.4% of patients, respectively). Median CAP values were higher in patients with HCV monoinfection than in those with coinfection (230 vs 215.5 dB/m, respectively; P < .001). With TE, the rate of advanced fibrosis (values F3–F4) was higher in HCV monoinfection than in coinfection (25.9% vs 14.8%, respectively; P <.001). With both LB and TE, advanced fibrosis (F3–F4) was significantly associated with moderate to severe steatosis (S2–S3) in HCV monoinfection compared with HIV/HCV coinfection (33.3% vs 4.4%, respectively for LB [P = 0.003] and 36.0% vs 29.0% for TE [P = 0.008]). Conclusions In patients with chronic HCV undergoing liver fibrosis staging, steatosis was detected more often with CAP than LB, with median CAP values higher in HCV monoinfection than HIV/HCV coinfection. Steatosis severity may be increasing in the modern HCV treatment era.

Abstract
Hepatocellular carcinoma (HCC) is a major complication of chronic hepatitis B (CHB) and chronic hepatitis C (CHC). Accumulating data suggest that antiviral treatment in both CHB and CHC reduces the incidence of HCC. Evidence is more consistent for interferon-based treatment in both CHB and CHC and for lamivudine in patients with CHB. However, more limited data suggest that other nucleos(t)ide analogues might also reduce the risk of HCC. In contrast, conflicting data have been reported on the effects of direct-acting antivirals on the incidence of HCC.

Abstract
BACKGROUND The nucleotide analog AL-335 is a pangenotypic hepatitis C virus (HCV) nonstructural protein (NS)5B inhibitor being evaluated as treatment for chronic HCV infection. METHODS This three-part randomized, double-blind study evaluated the safety and pharmacokinetics of single and multiple ascending oral doses of AL-335. Healthy volunteers (HVs) received single doses of AL-335 (100-1,200 mg) or placebo in a fasted or fed (400 mg) state. Non-cirrhotic subjects (HCV genotype [GT]1-4) and GT1-infected subjects with Child Pugh A cirrhosis received multiple doses of AL-335 (400, 800, 1,200 mg) or placebo once daily (QD) for 7 days. RESULTS Forty-eight HVs and 64 subjects with HCV GT1-4 were randomized and received treatment. AL-335 was well tolerated in HVs and HCV-infected subjects with/without cirrhosis. AL-335 was rapidly absorbed and converted to the metabolites ALS-022399 and ALS-022227. ALS-022227 exposure increased less than dose-proportionally and was unaffected by food, while AL-335 and ALS-022399 exposure increased with food by 85% and 50%, respectively, in HVs. Rapid and dose-dependent reductions in HCV-RNA were observed in GT1-infected subjects. In non-cirrhotic, GT1-4-infected subjects receiving AL-335 800 mg QD, potent antiviral activity was observed, regardless of genotype (mean maximum reductions in HCV-RNA of 4.0-4.8 log10 IU/mL). The same dose in GT1-infected cirrhotic subjects resulted in a 3.5 log10 IU/mL mean maximum reduction in HCV-RNA. CONCLUSIONS AL-335 was well tolerated when administered as single and multiple doses, with an acceptable pharmacokinetic profile. The drug also demonstrated potent antiviral activity in HCV GT1-4-infected subjects, including GT1-infected subjects with cirrhosis.

Abstract
Background: Hepatitis C virus (HCV) screening is traditionally performed using an enzyme-linked immunosorbent assay (ELISA), and HCV infection is confirmed by measuring the viral load using polymerase chain reaction (PCR). An alternative screening approach is to use only PCR, without the ELISA pretest. Methods: We compared the cost ratio of screening for HCV using 2 approaches: (1) ELISA followed by PCR testing, and (2) PCR testing alone. The results were analyzed using a decision analysis model. A sensitivity analysis and a threshold analysis were performed by varying both the prevalence of HCV infection (to encompass populations in which viral infection is overrepresented) as well as the costs of PCR testing. Results: Under baseline assumptions, the costs of PCR testing alone were substantially greater than the combination of ELISA and PCR testing. The cost per patient screened using combination testing was $42.30, whereas testing with only PCR cost $200.00 per patient. The prevalence of HCV had a greater impact on the cost ratio than did the costs of laboratory tests. The use of PCR testing alone became less costly only when the prevalence of HCV infection was greater than 69.5%. Otherwise, the costs of the 2 approaches were similar when the cost of PCR was 1% of that of ELISA. Conclusion: From a pharmacoeconomic basis, the current approach of HCV screening (ie, using ELISA and PCR testing) was found to be the less expensive screening strategy in a general US population and for most cohorts in which HCV infection was noted to be overrepresented. Screening for HCV is less costly using solely PCR testing only when the prevalence of HCV infection is greater than 69.5%.

Abstract
To examine mid-term benefits on hepatic complications, extrahepatic clinical syndromes and quality of life associated with HCV cure; to review the few safety issues linked to oral direct-acting antivirals (DAAs); and to discuss the potential population benefits of reducing the burden of HCV infection. DAAs cure HCV infection in more than 95% of patients. The halting of liver inflammation and fibrosis progression translates into both hepatic and extrahepatic benefits and reduces the need for liver transplantation. A reduction in the frequency of extrahepatic manifestations such as mixed cryoglobulinaemia and vasculitis and improvements in quality of life and fatigue have also been described. A few safety issues linked to DAAs such as the potential recurrence of aggressive HCC, the flares of hepatitis B virus in patients with overt or occult HBV infection are been discussed. Curing HCV infection also has a high potential to reduce the burden of HCV infection at the population level. With widespread scaling up of HCV treatment, several modeling studies suggest that major reductions in HCV prevalence and incidence are possible, and that elimination of viral hepatitis is an achievable target by 2030.

Abstract
Surrogate endpoints are often used in clinical trials, as they allow for indirect measures of outcomes (eg, shorter trials with less participants). Improvements in surrogate endpoints (eg, reduction in low density lipoprotein cholesterol, normalisation of glycated haemoglobin) achieved with an intervention are, however, not always associated with improvements in patient-important outcomes. The common tendency in evidence-based medicine is to view results based on surrogate endpoints as less certain than results based on long term, final patient-important outcomes and rate them as 'lower quality evidence'. However, careful appraisal of the validity of a surrogate endpoint as a measure of the final, patient-important outcome is more useful than an automatic judgement. In this guide, we use a contemporary and currently highly debated example of the surrogate endpoint 'sustained viral response' (ie, viral eradication considered to represent successful treatment) in patients treated for chronic hepatitis C virus. We demonstrate how the validity of a surrogate endpoint can be critically appraised to assess the quality of the evidence (ie, the certainty in estimates) and the implications for decision-making.

Abstract
What are the factors that influence human hepatitis C virus (HCV) infection, hepatitis status establishment, and disease progression? Firstly, one has to consider the genetic background of the host and HCV genotypes. The immunogenetic host profile will reflect how each infected individual deals with infection. Secondly, there are environmental factors that drive susceptibility or resistance to certain viral strains. These will dictate (I) the susceptibility to infection; (II) whether or not an infected person will promote viral clearance; (III) the immune response and the response profile to therapy; and (IV) whether and how long it would take to the development of HCV-associated diseases, as well as their severity. Looking at this scenario, this review addresses clinical aspects of HCV infection, following by an update of molecular and cellular features of the immune response against the virus. The evasion mechanisms used by HCV are presented, considering the potential role of exosomes in infection. Genetic factors influencing HCV infection and pathogenesis are the main topics of the article. Shortly, HLAs, MBLs, TLRs, ILs, and IFNLs genes have relevant roles in the susceptibility to HCV infection. In addition, ILs, IFNLs, as well as TLRs genes are important modulators of HCV-associated diseases. The viral aspects that influence HCV infection are presented, followed by a discussion about evolutionary aspects of host and HCV interaction. HCV and HIV infections are close related. Thus, we also present a discussion about HIV/HCV co-infection, focusing on cellular and molecular aspects of this interaction. Pharmacogenetics and treatment of HCV infection are the last topics of this review. The understanding of how the host genetics interacts with viral and environmental factors is crucial for the development of new strategies to prevent HCV infection, even in an era of potential development of pan-genotypic antivirals.
