Abstract
Chronic viral hepatitis B and C and non-alcoholic fatty liver disease (NAFLD) have been widely acknowledged to be the leading causes of liver cirrhosis and hepatocellular carcinoma. As anti-viral treatment progresses, the impact of NAFLD is increasing. NAFLD can coexist with chronic viral hepatitis and exacerbate its progression. Oxidative stress has been recognized as a chronic liver disease progression-related and cancer-initiating stress response. However, there are still many unresolved issues concerning oxidative stress, such as the correlation between the natural history of the disease and promising treatment protocols. Recent findings indicate that oxidative stress is also an anti-cancer response that is necessary to kill cancer cells. Oxidative stress might therefore be a cancer-initiating response that should be down regulated in the pre-cancerous stage in patients with risk factors for cancer, while it is an anti-cancer cell response that should not be down regulated in the post-cancerous stage, especially in patients using anti-cancer agents. Antioxidant nutrients should be administered carefully according to the patients’ disease status. In this review, we will highlight these paradoxical effects of oxidative stress in chronic liver diseases, pre- and post-carcinogenesis.

Abstract
Liver vessel density can be evaluated by an imaging biomarker diffusion-derived vessel density (DDVD): DDVD/area(b0b2) = Sb0/ROIarea0 - Sb2/ROIarea2, where Sb0 and Sb2 refer to the liver signal when b is 0 or 2 (s/mm2); ROIarea0 and ROIarea2 refer to the region of interest (ROI) on b = 0 or 2 images; and Sb2 may be replaced by Sb15 (b = 15). This concept was validated in this study. Liver diffusion images were acquired at 1.5 T. For a scan-rescan repeatability study of six subjects, b values of 0 and 2 were used. The validation study was composed of 26 healthy volunteers and 19 consecutive suspected chronic viral hepatitis B patients, and diffusion images with b values of 0, 2, 15, 20, 30, 45, 50, 60, 80, 100, 200, 300, 600, and 800 were acquired. Four patients did not have liver fibrosis, and the rest were four stage 1, three stage 2, four stage 3, and one stage 4 patients, respectively. The intraclass correlation coefficient for repeatability was 0.994 for DDVD/area(Sb0Sb2) and 0.978 for DDVD/area(Sb0Sb15). In the validation study, DDVD/area(Sb0Sb2) and area(Sb0Sb15) were 14.80 ± 3.06 and 26.58 ± 3.97 for healthy volunteers, 10.51 ± 1.51 and 20.15 ± 2.21 for stage 1-2 fibrosis patients, and 9.42 ± 0.87 and 19.42 ± 1.89 for stage 3-4 fibrosis patients. For 16 patients where IVIM analysis was performed, a combination of DDVD/area, PF, and Dfast achieved the best differentiation for nonfibrotic livers and fibrotic livers. DDVD/area were weakly correlated with PF or Dfast. Both DDVD/area(Sb0Sb2) and area(Sb0Sb15) are useful imaging biomarkers to separate fibrotic and nonfibrotic livers, with fibrotic livers having lower measurements.

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
Liver fibrosis due to viral or metabolic chronic liver diseases is a major challenge of global health. Correlating with liver disease progression, fibrosis is a key factor for liver disease outcome and risk of hepatocellular carcinoma (HCC). Despite different mechanism of primary liver injury and disease-specific cell responses, the progression of fibrotic liver disease follows shared patterns across the main liver disease etiologies. Scientific discoveries within the last decade have transformed the understanding of the mechanisms of liver fibrosis. Removal or elimination of the causative agent such as control or cure of viral infection has shown that liver fibrosis is reversible. However, reversal often occurs too slowly or too infrequent to avoid life-threatening complications particularly in advanced fibrosis. Thus, there is a huge unmet medical need for anti-fibrotic therapies to prevent liver disease progression and HCC development. However, while many anti-fibrotic candidate agents have shown robust effects in experimental animal models, their anti-fibrotic effects in clinical trials have been limited or absent. Thus, no approved therapy exists for liver fibrosis. In this review we summarize cellular drivers and molecular mechanisms of fibrogenesis in chronic liver diseases and discuss their impact for the development of urgently needed anti-fibrotic therapies.

Abstract
Hepatocellular carcinoma (HCC) is the most common primary liver cancer and is the second leading cause of cancer-related death worldwide. Fibrosis and cirrhosis are important risk factors for the development of HCC. Hepatic myofibroblasts are the cells responsible for extracellular matrix deposition, which is the hallmark of liver fibrosis. It is believed that myofibroblasts are predominantly derived from hepatic stellate cells (HSCs), also known as Ito cells. Nevertheless, depending on the nature of insult to the liver, it is thought that myofibroblasts may also originate from a variety of other cell types such as the portal fibroblasts (PFs), fibrocytes, hepatocytes, hepatic progenitor cells (HPCs), and mesothelial cells. Liver myofibroblasts are believed to transform into cancer-associated fibroblasts (CAFs) while HCC is developing. There is substantial evidence suggesting that activated HSCs (aHSCs)/cancer-associated fibroblasts (CAFs) may play an important role in HCC initiation and progression. In this paper, we aim to review current literature on cellular origins of myofibroblasts with a focus on hepatitis B virus (HBV)- and hepatitis C virus (HCV)-induced hepatic fibrosis. We also address the role of aHSCs/CAFs in HCC progression through the regulation of immune cells as well as mechanisms of evolvement of drug resistance.

Abstract
We evaluated the changes of gadoxetic acid uptake of the liver parenchyma after hepatitis C virus (HCV) eradication by direct-antiviral agent (DAA) therapy. The increase rate of the liver-to-muscle signal intensity ratio, the skewness and the kurtosis were calculated in the hepatobiliary phase. After sustained virological response, gadoxetic acid uptake of the liver parenchyma increased, but became heterogeneous. Our study proved that HCV eradication by DAA therapy could significantly affect gadoxetic acid uptake.

Abstract
BACKGROUND The real-world, long-term benefits of sustained virologic response (SVR) on the risk of variceal bleeding remain unclear. AIM To assess the association between DAA-induced SVR and post-treatment variceal bleeding METHODS: We identified patients who initiated DAA-only anti-viral treatments in the United States Veterans Affairs healthcare system from 2013 to 2015. We followed patients until 1 January 2019 for the development of gastro-oesophageal variceal bleeding defined by diagnostic codes. We used multivariable Cox proportional hazards regression to assess the association between SVR and development of variceal bleeding, adjusting for potential confounders. RESULTS Among 33 582 DAA-treated patients, 549 (1.6%) developed variceal bleeding after treatment (mean follow-up 3.1 years). Compared to no SVR, SVR was associated with a significantly lower incidence of variceal bleeding among all patients (0.46 vs 1.26 per 100 patient-years, adjusted hazard ratio [AHR] 0.66, 95% CI 0.52-0.83), among patients with pre-treatment cirrhosis (1.55 vs 2.96 per 100 patient-years, AHR 0.73, 95% CI 0.57-0.93) and among patients without pre-treatment cirrhosis (0.07 vs 0.29 per 100 patient-years, AHR 0.33, 95% CI 0.17-0.65). The risk of variceal bleeding after treatment was lower in those who achieved SVR vs no SVR among patients who had non-bleeding varices (3.5 vs 4.9 per 100 patient-years) or bleeding varices (12.9 vs 16.4 per 100 patient-years) diagnosed before treatment, but these differences were not statistically significant in adjusted analyses. CONCLUSION DAA-induced SVR is independently associated with a lower risk of variceal bleeding during long-term follow-up in patients with and without pre-treatment cirrhosis. These findings demonstrate an important real-world benefit of DAA treatment.

Abstract
The diagnostic assessment of liver injury is an important step in the management of patients with chronic liver disease (CLD). Although liver biopsy is the reference standard for the assessment of necroinflammation and fibrosis, the inherent limitations of an invasive procedure, and need for repeat sampling, have led to the development of several non-invasive tests (NITs) as alternatives to liver biopsy. Such non-invasive approaches mostly include biological (serum biomarker algorithms) or physical (imaging assessment of tissue stiffness) assessments. However, currently available NITs have several limitations, such as variability, inadequate accuracy and risk factors for error, while the development of a newer generation of biomarkers for fibrosis may be limited by the sampling error inherent to the reference standard. Many of the current NITs were initially developed to diagnose significant fibrosis in chronic hepatitis C, subsequently refined for the diagnosis of advanced fibrosis in patients with non-alcoholic fatty liver disease, and further adapted for prognostication in CLD. An important consideration is that despite their increased use in clinical practice, these NITs were not designed to reflect the dynamic process of fibrogenesis, differentiate between adjacent disease stages, diagnose non-alcoholic steatohepatitis, or follow longitudinal changes in fibrosis or disease activity caused by natural history or therapeutic intervention. Understanding the strengths and limitations of these NITs will allow for more judicious interpretation in the clinical context, where NITs should be viewed as complementary to, rather than as a replacement for, liver biopsy.

Abstract
Although endoscopy is the recommended method for detecting esophageal varices, noninvasive methods for diagnosing esophageal varices are needed to avoid unnecessary invasive endoscopic examinations. In recent years, many studies have been performed to predict the presence of high-risk varices in noninvasive ways. The most widely used tools for noninvasive screening for esophageal varices are the Baveno VI and expanded Baveno VI criteria. Even these accepted criteria are not 100% accurate and have some limitations. Here, we summarize the current literature on the noninvasive diagnosis of esophageal varices in liver cirrhosis patients and highlight the remaining issues.

Hepatic fibrogenesis is a pathophysiological outcome of chronic liver injury hallmarked by excessive accumulation of extracellular matrix proteins. Fibrosis is a dynamic process that involves cross-talk between parenchymal cells (hepatocytes), hepatic stellate cells, sinusoidal endothelial cells and both resident and infiltrating immune cells. In this review, we focus on key cell-types that contribute to liver fibrosis, cytokines, and chemokines influencing this process and what it takes for fibrosis to regress. We discuss how mitochondria and metabolic changes in hepatic stellate cells modulate the fibrogenic process. We also briefly review how the presence of fibrosis affects development of hepatocellular carcinoma.

Liver Int 2019; 39:2061-2065. [PMID: 31365178 PMCID: PMC11340272 DOI: 10.1111/liv.14203] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/24/2019] [Revised: 07/02/2019] [Accepted: 07/28/2019] [Indexed: 12/29/2022]
Abstract
Platelet (PLT) count is included in non-invasive scores assessing liver fibrosis in patients with chronic liver disease. Improvement in fibrosis scores after antiviral treatment for hepatitis C virus (HCV) has been interpreted as indicative of an improvement in fibrosis. HCV itself can lower PLT and, therefore, an increase in PLT would be expected after viral elimination irrespective of pretreatment fibrosis stage. The aim of this study was to investigate this hypothesis by assessing changes in PLT after viral elimination in patients with chronic HCV stratified by the absence or presence of cirrhosis. METHODS Retrospective analysis of patients with chronic HCV infection treated with direct-acting antivirals (DAAs) who achieved viral elimination and in whom PLT were obtained prior to treatment, at first negative HCV-RNA, at treatment completion and at 6 months, and 1 year after treatment completion. Comparisons were made between patients with and without cirrhosis. RESULTS A total of 420 patients with chronic HCV were treated, of which 208 were excluded, leaving 212 patients eligible for analysis (142 without cirrhosis, 70 with cirrhosis). Overall, a significant increase in PLT was observed up to 1 year after antiviral treatment completion (P < .001). Changes in PLT between patients with and without cirrhosis were not significantly different at any of the time points. CONCLUSION Platelet count increased significantly in patients with HCV who achieved viral elimination irrespective of the absence or presence of cirrhosis. This suggests that changes in PLT post-viral elimination should not be interpreted as being reflective of changes in liver fibrosis or portal hypertension.

Abstract
Background Direct-acting antivirals (DAA) have revolutionized hepatitis C treatment, with high sustained virological response (SVR) rates reported, even in historically difficult-to-treat groups. SVR is associated with a decreased risk of hepatocellular carcinoma (HCC), need for transplantation, and overall and liver-related mortality. Data from real-life cohorts on the medium- to long-term outcomes of patients with advanced liver disease and DAA-induced SVR are still missing. Objectives To report and analyze the long-term outcomes of DAA-induced SVR in a real-life cohort of patients with advanced liver disease. Method In this retrospective, longitudinal, single-center study, we collected data from patients with chronic hepatitis C infection and advanced liver disease (cirrhosis or advanced fibrosis) that had initiated DAA treatment between February 2015 and January 2017. Results A total of 237 patients were included. A treatment completion rate of 98.7% and an SVR rate of 97.8% (intention to treat: 96.6%) were found. Of the 229 patients with SVR, 67.2% were cirrhotic (64.2% Child-Pugh class A; 3.1% Child-Pugh class B) and 32.8% had stage F3 fibrosis, with an average follow-up of 28 months. The overall mortality rate was 19/1,000 person-years and the liver-related mortality rate was 9.5/1,000 person-years. The hepatic decompensation incidence rate was 25/1,000 person-years and the HCC incidence rate was 11.6/1,000 person-years. There was a sustained increase in serum platelet values during up to 2 years of follow-up. A history of pretreatment decompensation and baseline platelet and albumin values were significantly associated with the occurrence of adverse liver events after the end of treatment. Conclusions A DAA-induced SVR remains durable and is associated with an excellent clinical prognosis in patients with compensated advanced liver disease and with improvement or disease stabilization in decompensated patients. SVR is associated with a low risk of - yet does not prevent - HCC occurrence or disease progression, especially in the presence of other causes of liver injury. It is recommended that these patients be kept under surveillance.

Abstract
Chronic liver diseases with different etiologies represent a major public health issue worldwide. Liver fibrosis is the common feature of almost all chronic liver diseases and remains a key determinant of clinical prognosis. Over the last two decades, basic science studies have uncovered molecular mechanisms underlying the pathophysiology of chronic liver diseases, leading to the recent development of new anti-fibrotic drugs. These new drugs target different steps in the pathophysiology of chronic liver injury: metabolism of glucose, lipids and bile acids, apoptosis, inflammation and fibrosis. Many targets are shared between non-alcoholic steatohepatitis (NASH) and cholestatic diseases, explaining why some drugs have been assessed concurrently in both conditions. This review reports the most recent clinical trials designed to treat liver fibrosis, with a special focus on NASH and cholestatic diseases.

Abstract
Hepatitis C Virus (HCV), a blood borne pathogen capable of causing severe liver disease, disproportionately affects veterans in the United States. While there are antiviral medications to treat HCV, stigma and trauma in this population may lead to avoidance of care. Those veterans who do undergo treatment have certain illness representations about HCV and its treatment. They undergo treatment even while facing stigma and trauma. The Common-Sense Model may be useful in elucidating how such representations, when matched to an appropriate illness prototype, may inform an action plan of how to respond to HCV. An exploration of the illness representations among veterans with HCV, and the effects of stigma and trauma on these representations, may help to explain how they exercise the choice to undergo treatment and may inform interventions to encourage treatment in veterans who have yet to do so.

Abstract
The New York City Department of Health and Mental Hygiene (DOHMH) implemented Project INSPIRE, an integrated model of hepatitis C care coordination and telementoring services, from 2014 to 2017. We evaluated the use of chronic care management (CCM) codes to sustain the intervention. DOHMH data were collected as part of a Healthcare Innovation Award from the Centers for Medicare & Medicaid Services (CMS). A retrospective cohort medical billing study was conducted by assigning INSPIRE activities to procedure codes in both facility and nonfacility settings. Rates for procedures were extracted from the CMS's 2018 fee schedules and added across the eligibility periods for Medicare enrollees. Reimbursement was adjusted on the basis of expected patient attrition and compared to costs. The minimum number needed to treat (NNT) to break even was calculated in each setting. Facility reimbursement was higher than costs, whereas nonfacility reimbursement was lower (both P < .01). The NNT was 23 patients in facilities and 33 patients in nonfacilities; 24 patients per care coordinator were treated annually in INSPIRE. CCM fees alone were insufficient to fully reimburse the costs in either setting. Implementation of an appropriate risk financing strategy is necessary to mitigate financial shortfalls when providing CCM services in facility settings.

Abstract
BACKGROUND Clinical worsening after achieving a sustained virological response (SVR) needs to be clarified and explained. Persistence of hepatitis C virus (HCV) core antigen interacts with the host proteins to interfere with signaling pathways and increases the susceptibility to hepatic carcinogenesis. OBJECTIVE This study aimed to investigate the risk factors that increase the progression of liver disease and hepatocellular carcinoma in a subgroup of HCV patients who achieved a SVR. PATIENTS AND METHODS Eighty-nine HCV patients with hepatic decompensation were selected 8.2 ± 1.8 months after achieving SVR24. HCV core antigen and HCV RNA were detected in peripheral blood mononuclear cells. Matched control (n = 100) and training (n = 200) groups were recruited. RESULTS Eighty-five patients showed a progression of Child-Turcotte-Pugh and model for end-stage liver disease scores, with positive RNA in peripheral blood mononuclear cell (357.4 ± 42.1 IU/million cell) and positive hepatitis C virus core antigen (n = 73); four patients were excluded. Susceptibility to decompensation and hepatocellular carcinoma after direct-acting antiviral drugs increased with age [odds ratio (OD) = 1.87], and was associated with male sex (OD = 1.65), diabetes (OD = 3.68), thrombocytopenia (OD = 2.44), pretreatment Alfa-fetoprotein (OD = 3.41), and occult HCV (OD = 4.1). CONCLUSION Clinical deterioration after SVR could be explained by occult HCV mainly in older male patients with diabetes and thrombocytopenia.

Abstract
PURPOSE The aim of this study was to evaluate the relationship between the liver stiffness measurement and the risk of developing hepatocellular carcinoma (HCC) in HCV cirrhotic patients undergoing new direct-acting antivirals. METHODS From April 2015 to April 2017, all consecutive HCV cirrhotic patients treated by direct-acting antivirals were enrolled. A liver stiffness measurement was computed at baseline, and an ultrasound evaluation was provided for all patients at baseline and every 6 months until 1 year after the stopping of the antiviral therapy. The diagnosis of HCC was performed according to international guidelines by imaging technique workup. RESULTS Two hundred and fifty-eight HCV patients with a diagnosis of cirrhosis were identified. The median liver stiffness was 25.5 kPa. Thirty-five patients developed HCC. Patients were divided into three groups, based on their liver stiffness: < 20 kPa (n = 72), between 20 and 30 kPa (n = 92) and > 30 kPa (n = 94). Compared to the < 20 kPa and 20-30 kPa groups, the > 30 kPa group showed a statistically significant increased risk of HCC (p = 0.019; HR 0.329; 95% CI 0.131-0.830). A ROC curve analysis to assess the overall predictive performance of liver stiffness measurement on the HCC risk was performed. The results allow us to identify a cutoff value of liver stiffness measurement equal to 27.8 kPa, which guarantees the highest sensitivity and specificity (respectively, 72% and 65%). CONCLUSIONS The data underline that the baseline liver stiffness measurement and ultrasound surveillance is a valuable tool for assessing the risk of HCC in cirrhotic patients undergoing the direct-acting antivirals treatment.

Abstract
Two polymorphisms in the promoter region of macrophage migration inhibitory factor (MIF) - rs755622 and rs5844572 - exhibit prognostic relevance in inflammatory diseases. The aim of this study was to investigate a correlation between these MIF promoter polymorphisms and the severity of hepatitis C virus (HCV)-induced liver fibrosis. Our analysis included two independent patient cohorts with HCV-induced liver fibrosis (504 and 443 patients, respectively). The genotype of the single nucleotide polymorphism (SNP) -173 G/C and the repeat number of the microsatellite polymorphism -794 CATT5-8 were determined in DNA samples and correlated with fibrosis severity. In the first cohort, homozygous carriers of the C allele in the rs755622 had lower fibrosis stages compared to heterozygous carriers or wild types (1.25 vs. 2.0 vs. 2.0; p = 0.03). Additionally, ≥7 microsatellite repeats were associated with lower fibrosis stages (<F2) (p = 0.04). Comparable tendencies were observed in the second independent cohort, where fibrosis was assessed using transient elastography. However, once cirrhosis had been established, the C/C genotype and higher microsatellite repeats correlated with impaired liver function and a higher prevalence of hepatocellular carcinoma. Our study demonstrates that specific MIF polymorphisms are associated with disease severity and complications of HCV-induced fibrosis in a stage- and context-dependent manner.

Abstract
Plasmacytoid dendritic cells (pDCs) are "natural" interferon α (IFNα)-producing cells. Despite their importance to antiviral defense, autoimmunity, and ischemic liver graft injury, because DC subsets are rare and heterogeneous, basic questions about liver pDC function and capacity to make cytokines remain unanswered. Previous investigations failed to consistently detect IFNα mRNA in HCV-infected livers, suggesting that pDCs may be incapable of producing IFNα. We used a combination of molecular, biochemical, cytometric, and high-dimensional techniques to analyze DC frequencies/functions in liver and peripheral blood mononuclear cells (PBMCs) of hepatitis C virus (HCV)-infected patients, to examine correlations between DC function and gene expression of matched whole liver tissue and liver mononuclear cells (LMCs), and to determine if pDCs can produce multiple cytokines. T cells often produce multiple cytokines/chemokines but until recently technical limitations have precluded tests of polyfunctionality in individual pDCs. Mass cytometry (CyTOF) revealed that liver pDCs are the only LMC that produces detectable amounts of IFNα in response TLR-7/8 stimulation. Liver pDCs secreted large quantities of IFNα (~2 million molecules of IFNα/cell/hour) and produced more IFNα than PBMCs after stimulation, p = 0.0001. LMCs secreted >14-fold more IFNα than IFNλ in 4 hours. Liver pDC frequency positively correlated with whole liver expression of "IFNα-response" pathway (R2 = 0.58, p = 0.007) and "monocyte surface" signature (R2 = 0.54, p = 0.01). Mass cytometry revealed that IFNα-producing pDCs were highly polyfunctional; >90% also made 2-4 additional cytokines/chemokines of our test set of 10. Liver BDCA1 DCs, but not BDCA3 DCs, were similarly polyfunctional. pDCs from a healthy liver were also polyfunctional. Our data show that liver pDCs retain the ability to make abundant IFNα during chronic HCV infection and produce many other immune modulators. Polyfunctional liver pDCs are likely to be key drivers of inflammation and immune activation during chronic HCV infection.

Abstract
BACKGROUND Whether achieving sustained virological response (SVR) in patients with hepatitis C attains complete elimination of hepatitis C virus (HCV) is unknown, because occult HCV infection (OCI), defined as the detection of HCV-RNA in hepatocytes or peripheral blood mononuclear cells (PBMC) in absence of serum HCV-RNA, may occur. We thus investigated the prevalence and clinical relevance of OCI. METHODS Subjects from three hospitals who had achieved serum HCV clearance, including 60 of Direct-acting antiviral agents (DAAs) induced SVR, 50 of pegylated interferon plus ribavirin (PR) induced SVR, and 30 of spontaneous resolution, were subjected to detect HCV-RNA in liver by robust RNAscope assay and PBMC by qPCR. Paired liver biopsies at baseline and at SVR24 were analyzed. RESULTS OCI was detected in 16 of 140 subjects (11.4%), with 15.0% in DAA-based group, 10.0% in PR group and 6.7% in spontaneously resolved group. In DAA-based subgroups, the incidence of OCI was gradually increased in group of solely DAA(s) therapy, combining DAA and PR therapy and combining DAA and ribavirin therapy. OCI is more frequent in patients with genotype 3. No correlation between baseline viral load, interleukin-28B genotype, baseline transaminases, post-SVR transaminases and OCI were found. However, OCI was significantly linked with severity of fibrosis and active inflammation at post-SVR, even considering basal fibrosis status. In addition, both the magnitude and the frequency of fibrosis regression were lower in patients with OCI than in those without OCI. In the multivariate analysis, PR therapy was identified an independent negative prognostic factor for both hepatic inflammation (P = .022) and fibrosis regression (P = .015). Importantly, we found HCV relapse in one of the OCI patients at 48 weeks after the end of PR treatment. CONCLUSIONS HCV-RNA can persist in hepatocytes and/or PBMC in a certain of patients who achieved spontaneous or treatment-induced HCV RNA clearance from serum and associated with persistent histological abnormality. Our findings provide new insights into cure of HCV and could influence the following-up scenario after SVR.

Abstract
OBJECTIVES Given the goal of hepatitis C virus elimination by 2030, World Health Organization guidelines recommend treatment of chronic hepatitis C (CHC) with pan-genotypic direct-acting antivirals, such as sofosbuvir/velpatasvir (SOF/VEL), SOF/VEL/voxilaprevir (VOX) or glecaprevir/pibrentasvir (GLE/PIB). The study evaluated the cost-effectiveness of pan-genotypic regimens in initial (SOF/VEL or GLE/PIB) and re-treatment (SOF/VEL/VOX or GLE/PIB+SOF+ribavirin (RBV)) of CHC. METHODS A Markov state-transition model projected lifetime CHC health and economic outcomes from the US payer perspective. Model inputs were sourced from clinical trials or published literature and validated by hepatologists. Model outcomes included numbers of advanced liver disease events, life-years and quality-adjusted life-years (QALYs) gained, and total lifetime costs. One-way sensitivity analyses were performed on model results. RESULTS SOF/VEL followed by SOF/VEL/VOX resulted in comparable cure rates to the GLE/PIB treatment pathway (99.94% vs. 99.93%, respectively). SOF-based regimens provided similar QALYs at a lower lifetime cost versus a GLE/PIB treatment pathway ($30,749 vs. $36,255), resulting in cost savings of $5,506 per patient. Results were robust in sensitivity analyses. CONCLUSION SOF/VEL followed by SOF/VEL/VOX leads to comparable cure rates in the overall CHC population relative to the GLE/PIB treatment pathway. Based on wholesale acquisition prices, the SOF/VEL treatment pathway led to lower lifetime costs.

Abstract
The gut microbiota is involved in the maintenance of the homeostasis of the human body and its alterations are associated with the development of different pathological conditions. The liver is the organ most exposed to the influence of the gut microbiota, and recently important connections between the intestinal flora and hepatocellular carcinoma (HCC) have been described. In fact, HCC is commonly associated with liver cirrhosis and develops in a microenvironment where inflammation, immunological alterations, and cellular aberrations are dramatically evident. Prevention and diagnosis in the earliest stages are still the most effective weapons in fighting this tumor. Animal models show that the gut microbiota can be involved in the promotion and progression of HCC directly or through different pathogenic mechanisms. Recent data in humans have confirmed these preclinical findings, shedding new light on HCC pathogenesis. Limitations due to the different experimental design, the ethnic and hepatological setting make it difficult to compare the results and draw definitive conclusions, but these studies lay the foundations for a pathogenetic redefinition of HCC. Therefore, it is evident that the characterization of the gut microbiota and its modulation can have an enormous diagnostic, preventive, and therapeutic potential, especially in patients with early stage HCC.

Abstract
PURPOSE OF REVIEW Hepatitis C virus (HCV) infection has been the leading cause of cirrhosis in the United States now for the last several decades. With the introduction of highly effective direct acting antiviral (DAA) drugs, cure rates are now almost 100%. With this explosion of effective therapy, it is possible that many patients with HCV may have reversion in fibrosis. The purpose of this review is, therefore, to report on recent findings in this field. RECENT FINDINGS Older data that examined the effect of interferon-based HCV therapy indicate that fibrosis reverses after HCV eradication. More recent work in the DAA era similarly indicates that fibrosis is reversible. A caveat is that DAA therapy causes rapid viral clearance, and appears to lead to rapid reductions in inflammation. Some tools (such as transient elastography), which may also reflect the inflammatory response, and thus may 'overestimate' of fibrosis reversal. However, emerging data suggesting improved outcomes in patients with cirrhosis after HCV clearance support the concept that even cirrhosis reverses in some patients. SUMMARY Fibrosis (and cirrhosis) reversion, to some extent, occurs after HCV clearance. This topic is vitally important and information continues to emerge; more data on this subject are expected and needed.

Abstract
Introduction: Within the past decade, antiviral treatment for chronic hepatitis C virus (HCV) infection has evolved from interferon (IFN)-based regimens to IFN-free oral direct-acting antiviral agents (DAAs). However, data on long-term outcomes in HCV patients treated by DAAs are limited and complex. Areas covered: Original studies and meta-analyses reporting data on the impacts of IFN - and DAA-based treatments on late relapse, liver fibrosis/cirrhosis, decompensation progression, hepatocellular carcinoma (HCC) occurrence and recurrence, need for liver transplantation, mortality, and other topics of interest for long-term observation of HCV patients treated with DAAs. Articles published up to June 2018, and proceedings from annual meetings of major international liver diseases associations (from 2015 to June 2018) were reviewed. Relevant references from selected papers were also reviewed. Expert opinion: In HCV patients treated with DAAs or IFN-based regimens, late relapse beyond 12 weeks after completion of treatment is uncommon. Results from long-term follow-up studies suggest responders to antiviral treatment achieve benefits on regression of fibrosis/cirrhosis, decreasing risk of progression to liver decompensation, reductions in the need for liver transplantation and mortality. Well-designed studies with robust comparisons are needed to determine the effect of DAAs on the recurrence of HCC in the future.

Abstract
AIMS The liver function of patients with hepatitis C virus (HCV) infection who obtained sustained virologic response (SVR) has been known to improve after HCV eradication. However, a predictor of liver function after SVR has not been definitively identified. The aim of this retrospective study was to identify a predictor of deteriorated liver function and Fibrosis-4 (FIB-4) index after SVR was achieved by direct-acting antiviral (DAA) treatment. METHODS This study retrospectively enrolled 248 patients who obtained SVR by DAA treatment. None of the patients developed hepatocellular carcinoma during this study. Liver function was assessed at the end of treatment (EOT) and at 24, 48, 72, and 96 weeks after EOT. RESULTS At 96 weeks after EOT, the serum aspartate aminotransferase and alanine aminotransferase levels were significantly decreased from those at EOT. The platelet count was significantly increased from 14.9 × 104 /μL at EOT to 17.1 × 104 /μL at 96 weeks after EOT. Ten patients showed an increased FIB-4 (>1.00) index. Multivariate analysis with 171 patients who underwent endoscopic assessment revealed that the presence of varices was an independent predictor of deterioration in the FIB-4 index (odds ratio, 5.56; P = 0.041). CONCLUSION Most of the study patients who obtained SVR showed improved liver function after EOT. Patients without increasing platelet counts after SVR due to DAA therapy should be evaluated for complications induced by portal hypertension.

Abstract
BACKGROUND The outcome of patients with chronic hepatitis C virus infection (HCV) and advanced, compensated liver disease after sustained virological response (SVR) to direct-acting antivirals (DAAs) has not yet been completely depicted. We aimed to assess the clinical, biochemical and instrumental outcome of patients with advanced, compensated chronic HCV-related liver disease with DAA-induced SVR to DAAs and who had at least 1-year follow-up. MATERIALS AND METHODS Fifty-two patients with cirrhosis (n = 27) and fibrosis stage F3 (n = 25) followed up for a median of 60 weeks after successful DAA treatment were included. Laboratory work-up, including APRI and FIB-4 scores, liver transient elastography and measurement of the spleen bi-polar diameter were carried out before treatment and at the end of follow-up. RESULTS Liver stiffness decreased (P < 0.0001) from a median baseline of 15.2 kPa (12.0-20.0) to 9.3 kPa (7.5-12.0) at follow-up. A liver stiffness value suggestive of the presence (ie, ≥21.0 kPa) of clinically significant portal hypertension was found in 13 patients (25.0%) at baseline and in seven patients (13.5%) at follow-up (P = 0.037). Both APRI (P < 0.0001) and FIB-4 score (P = 0.025) progressively decreased, while platelet count increased (143 × 109 /L [117-176] to 153 × 109 /L [139-186], P = 0.003), and spleen bi-polar diameter decreased (120 mm [112-123] to 110 mm [102-116], P = 0.0009) from baseline to the end of follow-up. CONCLUSIONS In patients advanced, compensated chronic liver disease, liver stiffness significantly improves in the long-term after SVR, and this improvement is accompanied by an amelioration of indirect indices of liver fibrosis and function, and by a decrease in parameters of portal hypertension.

Abstract
Direct-acting antiviral (DAA) therapies for chronic hepatitis C virus (HCV) infection achieve high cure rates, reducing HCV-related disease progression to cirrhosis and hepatocellular carcinoma. We aim to evaluate the impact of DAAs on US liver transplant (LT) waitlist outcomes. We retrospectively evaluated US adults (age ≥18) with and without chronic HCV listed for LT before and after the widespread use of sofosbuvir, allowing a 6-month period after approval (Era 1: 1/1/2002-5/31/2014 vs Era 2: 6/1/2014-12/31/2016) using the United Network for Organ Sharing registry. Overall, LT waitlist survival and likelihood of receiving LT were evaluated with multivariate Cox regression models. From 2002 to 2016, 158 045 patients were listed for LT. While the number of patients listed for HCV has been decreasing since 2012, the proportion of HCV patients with concurrent HCC is increasing by 3.33% per year (R2 : 0.99, P < 0.001 by simple linear regression). While there was no difference in likelihood of LT between HCV and non-HCV patients, those listed in Era 2 had lower likelihood of LT (HR: 0.91, P < 0.001), more pronounced in the HCV cohort (HR: 0.83, P < 0.001) compared to the non-HCV cohort (HR: 0.93, P < 0.001). Compared to non-HCV patients, higher waitlist mortality was seen in HCV patients in Era 1 (HR: 1.08, P < 0.001) but not in Era 2 (HR: 1.02, P = 0.75). Since the introduction of DAAs for HCV treatment, number of patients with HCV listed for LT has declined. In the post-DAA era, HCV patients on the LT waitlist had improved waitlist mortality.

Abstract
Background Interferon therapy is used as a line of treatment of chronic hepatitis C virus (HCV) in several areas of the world including Egypt. Objective Our aim was to investigate the value of hepatic progenitor cells (HPCs) in predicting response of patients with chronic HCV, genotype 4 to pegylated interferon (PEGIFN) plus ribavirin (RBV) therapy. Methods Pre-treatment liver biopsies obtained from 110 patients with chronic HCV, genotype 4 were examined immunohistochemically for HPCs using cytokeratin19. The mean number of HPCs as ductular reaction (DR) and as isolated progenitor cells (IPCs) was counted in each case. The patients were classified into: those with sustained virological response (SVR) and those who did not achieve SVR. The results were compared between the two groups. Also, the relationships between HPCs and other clinico-pathologic variables were estimated using multivariate analysis. Results The mean number of HPCs was the only independent predictor of therapeutic response, being significantly higher in non-responders (P = 0 for DR and P = 0.03 for IPCs). On the other hand, fibrosis stage and steatosis were the only independent factors which showed a significant direct association with the mean number of HPCs in the form of DR and IPCs (P = 0 for each). Conclusion The number of HPCs provides prognostic information in chronic HCV since it is significantly associated with stage of fibrosis. More importantly, it can be used as a marker to predict response of patients with chronic HCV to PEGIFN plus RBV therapy.

Abstract
BACKGROUND Recent two studies reported that intravoxel incoherent motion (IVIM) analysis can separate healthy livers and viral hepatitis B (VHB) induced liver fibrosis. However, in these two studies the starting b value for bi-exponential decay analysis was b =10 and 15 s/mm2 respectively. The current study has two primary aims. The first is to further confirm the diagnostic value of IVIM in detecting liver fibrosis. The second is to test whether by sampling very low b value densely, then b =0 s/mm2 image could be included to improve IVIM's diagnostic performance. METHODS This was a prospective study with data acquired at the Third Xiangya Hospital of Central South University, Changsha, China. Healthy volunteers and patients suspected of VHB induced liver fibrosis with liver biopsy performed, as well as hepatocellular carcinoma patients scheduled for surgery, were recruited. All the hepatocellular carcinoma patients had liver fibrosis. After exclusions based on pre-defined criteria for image data quality, for IVIM analysis this study included 20 healthy volunteers; 4 chronic VHB patients with biopsy showing no liver fibrosis; 11 stage-1 liver fibrosis patients, 10 stage-2 liver fibrosis patients, 2 stage-3 liver fibrosis patients, and 5 stage-4 liver fibrosis patients. In the liver fibrosis patients, 1, 19, and 8 cases had inflammation grade-0, grade-1, and grade-2 respectively. The reference IVIM bi-exponential decay curve fitting analysis was segmented fitting performed with b =2 s/mm2 image as the starting point and a threshold-b of 60 s/mm2. This reference fitting method was compared with threshold-b of 40 s/mm2, full fitting, fitting starting from b =0, 5, and 10 s/mm2 respectively. The potential correlation between IVIM readouts and liver function was assessed for the liver fibrosis patients. RESULTS Based on the smaller coefficient of variation (CoV) for the volunteer group and the smaller patient/volunteer ratios [= (mean measurement for patient groups)/(mean measurement for healthy volunteers)], the comparison of fitting methods favored the reference approach starting from b =2 s/mm2 with a threshold-b of 60 s/mm2. The IVIM measures of four patients without liver fibrosis resembled those of healthy subjects. PF offered the best diagnostic value for separating healthy livers and fibrotic livers, and a threshold of PF =0.1406 separated all fibrotic livers and healthy livers with an exception of one hepatocellular carcinoma patient (fibrosis grade-2/inflammation grade-2). The correlation between fibrosis grading and inflammation grading was weakly positive; while compared with fibrotic livers with inflammation grade-1, fibrotic livers with inflammation grade-2 showed a trend of higher Dfast. A weak correlation is shown with lower PF and lower Dfast associated with lower total protein, lower albumin; higher alanine transaminase, higher aspartate transaminase; higher total bilirubin, and higher direct bilirubin. CONCLUSIONS Segmented-fitting with threshold-b =60 s/mm2 and starting from non-zero very low b value outperforms other methods. IVIM has high sensitivity in detecting liver fibrosis, and PF and Dfast have potential correlation with serum liver function biomarkers. IVIM measures and liver fibrosis grading are not in a linear relationship.

Health-related quality of life in hepatitis C patients who achieve sustained virological response to direct-acting antivirals: a comparison with the general population. Qual Life Res 2019; 28:1477-1484. [PMID: 30666549 DOI: 10.1007/s11136-019-02111-1] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 01/11/2019] [Indexed: 12/18/2022]
Abstract
PURPOSE To compare health-related quality of life (HRQoL) between hepatitis C patients who achieve sustained virological response (SVR) to direct-acting antivirals and a sex- and age-paired sample of the general population. METHODS HRQoL was evaluated in patients recruited in Navarre, Spain, from May 2016 to April 2017 at baseline and after SVR, using the EQ-5D-5L questionnaire. Both results were compared to those of general population of the same sex and age obtained from the 2011/12 National Health Survey in Spain. Observed/expected (O/E) ratios for health dimensions and differences between O-E in EQ-5D utility and visual analogical scale (VAS) scores were calculated. RESULTS 206 patients were studied. Before treatment, patients had more problems than the general population in every domain of EQ-5D-5L, except in self-care dimension (O/E = 1.1). After SVR, patients continued having more limitation, especially for usual activities (O/E = 3.1), anxiety/depression (O/E = 2.8) and EQ-5D utility (- 0.086, p < 0.001); however, differences in VAS score between patients and general population disappeared (74.8 vs 76.5, p = 0.210). F0-F1 patients with SVR had minor differences with the general population in EQ-5D-5L dimensions, utility and VAS score. Although cirrhotic patients also reduced that difference, they still had worse HRQoL, especially in usual activities, self-care, EQ-5D utility (- 0.152, p < 0.001) and VAS score (- 8.5, p = 0.005). CONCLUSIONS HRQoL of chronic hepatitis C patients remains lower than that of the general population despite viral clearance, with primary problems in usual activities and anxiety/depression. Knowledge of these on-going problems despite cure serves to guide healthcare interventions and patient's follow-up.

Abstract
BACKGROUND AND AIM Previous studies have reported that sustained virological response (SVR) to interferon-based treatment reduces the risk of mortality in chronic hepatitis C (CHC) patients, mainly in cirrhotic patients. A population-based study reported that metabolic risk factors increase the risk of mortality in CHC patients. We aim to investigate the association between SVR, metabolic risk factors and mortality in CHC patients with and without advanced fibrosis. METHODS We collected data from 1452 CHC patients who underwent interferon-based therapy. All patients underwent liver biopsy prior to therapy. Mild fibrosis was defined as a modified Knodell score of 0-2, while advanced fibrosis was defined as a score of 3-4. RESULTS 1452 patients were followed up for a median (IQR) of 6.6 (4.2-9.4) years, 1124 patients (77.4%) achieved SVR, 619 patients (42.6%) were advanced fibrosis. 14 patients with mild fibrosis and 55 patients with advanced fibrosis died during follow-up period. According to multivariate Cox regression analyses, SVR reduced the risks of all-cause mortality (HR, 0.21; 95% CI, 0.12-0.37; P<0.001), liver-related mortality (HR, 0.19; 95% CI, 0.10-0.38; P < .001), and non-liver-related mortality (HR, 0.26; 95% CI, 0.10-0.71; P = 0.009) in the patients with advanced fibrosis. SVR also reduced the risk of liver-related mortality (HR, 0.09; 95% CI, 0.01-0.60; P = 0.013) in the patients with mild fibrosis. Anti-hypertensive treatment increased the risks of all-cause mortality (HR, 6.1; 95% CI: 1.66-22.54; P = 0.006) and liver-related mortality (HR, 12.3; 95% CI: 1.4-108.5; P = 0.02) in the patients with mild fibrosis. CONCLUSION SVR and metabolic risk factors are associated with mortality in CHC patients given interferon-based treatment.

Abstract
There is a need for noninvasive biomarkers that can identify patients with progressive liver fibrosis and monitor response to antifibrotic therapy. An equally important need is identification of patients with spontaneous fibrosis regression, since they may not need treatment nor be included in clinical studies with fibrosis as end point. Circulating biomarkers, originating from defined fragments of the scar tissue itself, may serve as valuable tools for this aspect of precision medicine. We investigated a panel of serological collagen formation and degradation markers to identify patients likely to regress or progress in absence of a therapeutic intervention. Plasma samples from patients with moderate-stage hepatitis C receiving placebo treatment in a phase II trial of the peroxisome proliferator-activated receptor agonist farglitazar were included. The patients had matched liver biopsies at baseline and 52 wk of follow-up. Serological biomarkers of collagen formation (PRO-C3, PRO-C4, PRO-C5) and collagen degradation (C3M, C4M, and C6M) were analyzed. Logistic regression analysis including PRO-C3 and C6M identified subjects with progressive liver fibrosis with an AUROC of 0.91 ( P < 0.0001) and positive and negative predictive values (PPV/NPV) of 75.0%/88.6%. Low levels of PRO-C5 predicted a spontaneous regression phenotype, with an odds ratio of 33.8 times higher compared with patients with high levels ( P < 0.0025) with an AUROC of 0.78 ( P < 0.0001) and PPV/NPV of 60.0%/95.7%. Two collagen fragments (PRO-C3 and C6M) identified liver fibrosis progressors, and one collagen fragment (PRO-C5) identified liver fibrosis regressors. These biomarkers may improve patient stratification and monitor treatment efficacy in studies with fibrosis as clinical end point. NEW & NOTEWORTHY In this study we report two biomarkers of collagen fragments (PRO-C3 and C6M) that are able to identify liver fibrosis progressors while one biomarker (PRO-C5) identified liver fibrosis regressors. In particular, we present three noninvasive biomarkers that can be used to identify patients with progressive liver fibrosis, monitor response to antifibrotic therapy, and also identify the spontaneous liver fibrosis regression phenotype.

Abstract
BACKGROUND AND OBJECTIVE New direct-acting antivirals (DAAs) have high efficacy and tolerability in the treatment of hepatitis C virus (HCV) infection. The objective of this study was to assess the cost-effectiveness of elbasvir/grazoprevir (EBR/GZR) versus daclatasvir plus asunaprevir (DCV + ASV) in Chinese patients with chronic HCV genotype (GT) 1b infection stratified by cirrhosis status and treatment history. METHODS A cohort state-transition model was constructed to simulate the course of chronic HCV infection in patients stratified by cirrhosis status and treatment history. The model projected lifetime outcomes and costs in terms of HCV treatment, laboratory tests, clinical procedures, and hospitalizations. Mean age of the study cohort at baseline was 45 years, based on published sources. Sustained virologic response (SVR) rates were derived from clinical trials. Healthcare resource utilization and health utilities were extracted or estimated from published studies in Chinese populations. The stability of the base-case analysis was validated by deterministic and probabilistic sensitivity analyses. RESULTS In each subpopulation of Chinese patients, treatment with EBR/GZR dominated treatment with DCV + ASV, with lower costs and higher quality-adjusted life-years (QALYs). Sensitivity analysis demonstrated that EBR/GZR was the cost-effective option compared to DCV + ASV in 77.4-97.4% or 94.1-100% of model simulations in Chinese treatment-naïve or treatment-experienced patients, respectively, as the cost-effectiveness threshold changed from zero to US$24,150/QALY (three times GDP per capita in China). CONCLUSIONS Treatment with EBR/GZR was the cost-effective option for patients with chronic HCV GT1b infection in China, regardless of cirrhosis status or treatment history.

Abstract
BACKGROUND The cure of hepatitis C virus (HCV) infection may contribute to the reduction of liver fibrosis progression and potentially influence the gut-liver axis. AIM To investigate the influence of HCV infection eradication with direct-acting antivirals (DAAs) on the gut microbiota composition as well as on intestinal and systemic inflammatory parameters in patients with cirrhosis. METHODS Consecutive patients with HCV-related cirrhosis receiving DAA treatment were included. The gut microbiota composition, intestinal permeability, and inflammation were assessed before treatment and after 1 year. Clinical outcomes such as episodes of decompensation and markers of liver fibrosis were evaluated over a 2-year follow-up period. RESULTS The gut microbiota alpha diversity in cirrhotic patients, which was lower than that in healthy subjects, was significantly improved by the cure of HCV infection and a shift in the overall gut microbiota composition was observed compared to baseline. The abundance of potentially pathogenic bacteria (Enterobacteriaceae, Enterococcus, and Staphylococcus) was decreased after treatment. The gut microbiota composition was associated with the inflammatory profile and markers of liver fibrosis. Although a significant reduction in the serum levels of cytokines and chemokines was observed post-DAA treatment, measures of intestinal permeability and inflammation remained unchanged. CONCLUSIONS Cure of HCV infection with DAAs in patients with cirrhosis is associated with a modification of the gut microbiota, which correlates with fibrosis and inflammation but does not improve intestinal barrier function.

Abstract
Methods We applied multiparametric MRI to assess changes in liver composition, perfusion and blood flow in 17 patients before direct-acting antiviral (DAA) therapy and after treatment completion (within 12 weeks of last DAA tablet swallowed). Results We observed changes in hepatic composition indicated by a reduction in both liver longitudinal relaxation time (T1, 35 ± 4 ms), transverse relaxation time (T2, 2.5 ± 0.8 ms; T2* 3.0 ± 0.7 ms), and liver perfusion (28.1 ± 19.7 ml/100 g/min) which we suggest are linked to reduced pro-inflammatory milieu, including interstitial oedema, within the liver. No changes were observed in liver or spleen blood flow, splenic perfusion, or superior mesenteric artery blood flow. Conclusion For the first time, our study has shown that treatment of HCV with DAAs in patients with cirrhosis leads to an acute reduction in liver T1, T2 and T2* and an increase in liver perfusion measured using MR parameters. The ability of MRI to characterise changes in the angio-architecture of patients with cirrhosis after intervention in the short term will enhance our understanding of the natural history of regression of liver disease and potentially influence clinical decision algorithms. Key Points • DAAs have revolutionised the treatment of hepatitis C and achieve sustained virological response in over 95% of patients, even with liver cirrhosis. • Currently available non-invasive measures of liver fibrosis are not accurate after HCV treatment with DAAs, this prospective single-centre study has shown that MRI can sensitively measure changes within the liver, which could reflect the reduction in inflammation with viral clearance. • The ability of MRI to characterise changes in structural and haemodynamic MRI measures in the liver after intervention will enhance our understanding of the progression/regression of liver disease and could potentially influence clinical decision algorithms.

Abstract
BACKGROUND The improvement in liver histology is an important aim in the management of hepatitis C virus (HCV) infection. Previous studies suggest that antiviral treatment could reduce the progression of hepatic fibrosis, especially in patients with sustained virological response (SVR). However, most studies were limited by short-term evaluations and the liver stiffness was assessed by non-invasive methods. In our study, we performed a paired liver biopsy study aimed at analyzing the long-term histological changes in patients with SVR. METHODS We included 31 patients who had been previously treated with peginterferon plus ribavirin. All patients achieved SVR and had received pre- and post-treatment liver biopsies. The histological appearance of fibrosis and inflammation were assessed with METAVIR scoring system and Histological Activity Index (HAI) criteria. We analyzed several factors associated with the histological response. RESULTS The median interval between two biopsies was 93.0 months. The percentage of patients with fibrosis regression, stable, and progression were 19%, 45%, and 36%. A total of 71% of patients achieved inflammation improvement, whereas 6% and 23% of patients had stable disease and disease-progression, respectively. We showed that the patients without baseline advanced fibrosis and those having a lower baseline HAI score had higher risk of fibrosis worsening. Baseline fibrosis and necroinflammation status did not influence HAI change significantly. CONCLUSION The progression of hepatic fibrosis and inflammation can be reversed in some patients who had long-term virological suppression. Patients with advanced baseline fibrosis and higher inflammatory stages seemed to receive more histologic benefit from successful antiviral treatments.

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

Regression of liver fibrosis after curing chronic hepatitis C with oral antivirals in patients with and without HIV coinfection. AIDS 2018; 32:2347-2352. [PMID: 30096074 DOI: 10.1097/qad.0000000000001966] [Citation(s) in RCA: 51] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/15/2022]
Abstract
BACKGROUND Treatment with direct-acting antivirals (DAA) eradicates hepatitis C virus (HCV) from most chronic carriers. Information on regression of liver fibrosis and the influence of HIV is scarce in cured patients. METHODS All consecutive HCV-infected individuals treated with DAA at our institution were examined. Hepatic elastography was performed at baseline and at the time of SVR12. Liver fibrosis regression was defined as a shift from advanced fibrosis (Metavir F3-F4) to null-mild fibrosis (F0-F2) and/or a reduction greater than 30% kPa. AST to platelet ratio index (APRI) and fibrosis 4 (FIB-4) scores were calculated in parallel. RESULTS A total of 260 patients were treated with DAA. All but 14 achieved SVR12 and represented the study population. HIV confection was present in 42%. At baseline, 57.2% had advanced liver fibrosis with a median of 11 kPa, FIB-4 of 2.4, and APRI of 0.95. At the time of SVR12, a median reduction of 2.1 kPa (P < 0.001) was recognized using elastography. A significant fibrosis regression was seen in 40%, being more frequent in patients with baseline advanced fibrosis than in those with null-mild fibrosis (52.3 vs. 22.5%; P < 0.001). Even so, 41.2% of patients with baseline F3-F4 kept within cirrhotic scores. In multivariable analysis, only baseline stiffness was significantly associated with the extent of liver fibrosis regression. CONCLUSION HCV cure with DAA is associated with regression of liver fibrosis in most patients treated with DAA, as measured using elastography, FIB-4 and APRI. This benefit is more pronounced in patients with baseline advanced fibrosis and cirrhosis. The dynamics of liver fibrosis regression are not influenced by HIV coinfection.

Abstract
Hepatitis C virus (HCV) eradication by antivirals promote fibrosis modification. Whether host genetics determined fibrosis regression in chronic hepatitis C (CHC) patients with sustained virological response (SVR) is to be determined. One hundred and fifty-six SVR patients with paired liver biopsy before and after antivirals were enrolled. Host genetic factors including single nucleotide polymorphism rs17047200 of tolloid-like 1(TLL-1) were analyzed for their association with fibrosis modification. The proportions of improved, unchanged and worsening fibrotic stags were 39.1% (n = 61), 39.1% (n = 61), and 21.8% (n = 34), respectively. The rate of annual fibrotic improvement was 0.16 ± 0.79. There was a significant trend of increased fibrotic improvement rate in patients from F01 to F4 (P < 0.001). However, the rate of improvement seemed more limited in cirrhotic patients among those with advanced liver disease. Patients with fibrotic improvement had a significantly higher proportion of TLL-1 rs17047200 AA genotype compared to those without (92.5% vs. 79.3%, p = 0.039). Logistic regression analysis revealed that the TLL-1 rs17047200 AA genotype was the only independent factor associated with fibrosis improvement (odds ratio/95% confidence intervals: 3.2/1.01-10.12, p = 0.047). Compared with TLL-1 rs17047200 non-AA carriers, a significantly higher proportion of fibrosis improvement in AA genotype carriers was observed among patients with F0-2 (33.3% vs. 0%, p = 0.005) but not with F34 (70% vs. 80%, p = 1). We concluded that TLL-1 genetic variants determined fibrotic improvement in CHC with curative antivirals, particularly in patients with mild liver disease.

Abstract
UNLABELLED Progenitor-derived regeneration gives rise to the aberrant expression of biliary markers such as cytokeratin 7 (K7) and epithelial cell adhesion molecule (EpCAM) in hepatocytes. We aimed to describe the expression of these molecules in patients with compensated hepatitis C virus (HCV)-related cirrhosis and to investigate its potential influence on cirrhosis complications. Among patients with Child-Pugh A uncomplicated HCV-related cirrhosis enrolled in the prospective ANRS CO12 CirVir cohort, we selected individuals with a liver biopsy collected within 2 years before inclusion in the study. K7 and EpCAM immunostaining identified intermediate hepatobiliary cells. The influence of biliary marker expres-sion in hepatocytes on decompensation events and the occurrence of hepatocellular carcinoma (HCC) was studied using a multivariate Cox proportional hazards regression model. Among the 337 patients eligible for the study (men, 67%; median age, 52 years), 198 (58.8%) had biopsies with K7-positive hepatocytes including extensive staining in 40 (11.9%) and 203 had EpCAM-positive hepatocytes (60.6%). During follow-up (median, 54.2 months), 47 patients (14%) experienced a decompensation event, and HCC was diagnosed in 37 patients (11%). Extensive K7 staining was independently associated with the occurrence of a decompensation event (hazard ratio [HR], 3.00; 95% confidence interval [CI], 1.30-6.89; P = 0.010). EpCAM expression was independently associated with HCC occurrence (HR, 2.37; 95% CI, 1.07-5.23; P =0.033) along with age and a low prothrombin ratio. CONCLUSION Progenitor-derived regeneration depicted by K7 and EpCAM immunostaining of hepatocytes in liver biopsies of patients with compensated HCV-related cirrhosis marks a cirrhosis stage more prone to develop complications.

Abstract
Liver fibrosis is a reversible wound-healing response that occurs after liver injury. NADPH oxidases (NOXs) and reactive oxygen species (ROS) which are expressed in hepatocytes (HCs), hepatic stellate cells (HSCs), and Kupffer cells (KCs) play an important role in the development of hepatic fibrosis. In in vitro studies, we had shown that ursolic acid (UA) could reverse liver fibrosis by inhibiting the activation of NOX-mediated fibrotic signaling networks in HSCs. In this study, we verified that UA could alleviate CCl4-induced liver fibrosis by reducing the expression of NOXs/ROS in HCs, HSCs, KCs. Meanwhile, the phagocytic index α and clearance index K which represent phagocytosis of KCs were unchanged. Together, all our data demonstrated that UA induced the proliferation of HCs, promoted apoptosis in HSCs, and prevented activation of KCs in vivo by reducing the expression of NOXs/ROS in HCs, HSCs, KCs. Besides, UA had no effect on the host defense function.

Abstract
Since the incidence of chronic hepatitis C (CHC) increases steadily, the priority of national health care is to provide antiviral therapy (AVT) for the maximum number of patients infected with hepatitis C virus (HCV). The regimens including pegylated interferons (PEG-IFN) are still in demand in the Russian Federation. A number of clinical trials have been conducted to evaluate the efficacy and safety of cepeginterferon alpha-2b (cePEG-IFN alpha-2b), an original PEG-IFN-α developed in the Russian Federation. Their results have shown that cePEG-IFN alpha-2b in the two-component AVT regimen has at least no less clinical efficacy than PEG-IFN alpha-2b and PEG-INF alpha-2a in HCV monoinfected and HCV/HIV co-infected patients. The pooled analysis of data has indicated that the use of cePEG-IFN alpha-b in combination with ribavirin allows an average of 80% of the patients with HCV genotypes 2 and 3 and 62% of those with HCV genotype 1 to achieve a sustained virological response (SVR). In clinical practice when the two-component AVT regimen (cePEG-IFN alpha-b and ribavirin) was used in patients with early-stage CHC and mild fibrosis, SVR was recorded in 90.7% of the patients with HCV genotype 2/3 and in 75% of those with HCV genotype 1. The experience in using cePEG-IFN alpha-2b as a component of the three-component AVT regimen (simeprevir, cePEG IFN alfa-2b, and ribavirin) has been published. The observational program manly covered young patients with mild or moderate fibrosis. SVR was observed in 94% of the patients. Another paper describes the experience with the triple AVT therapy (simeprevir, cePEG-IFN alfa-2b, and ribavirin) in 22 patients, the majority of whom had advanced fibrosis. SVR was recorded in 71.4% of those who had completed treatment. Thus, an individual approach and assessment of predictive response factors to two- or three-component AVT regimens including cePEG-IFN alpha 2b can achieve successful treatment outcomes in most patients with CHC, which is, in some cases, more economically sound than interferon-free regimens used as first-line therapy.
