Abstract
Background Of liver-related disorders, cirrhosis is currently the leading cause of death and has become a significant global public health concern. Aspartate aminotransferase to platelet ratio index (APRI), a newer prognostic modality, is a very effective noninvasive diagnostic for identifying advanced liver fibrosis. Methods A prospective observational study was conducted among individuals with liver disease, 100 cases and 100 controls for two years. All the sociodemographic details, clinical features of the patients, and clinical findings such as prothrombin time (PT), liver function tests, kidney function tests, and total blood count were recorded using a pretested semi-structured questionnaire. Results According to our survey results, 48% of the participants were between the ages of 40 and 60. Regarding aPTT (activated partial thromboplastin time) and liver function test characteristics (serum glutamic-oxaloacetic transaminase(SGOT), serum glutamic pyruvic transaminase (SGPT)), we showed a substantial difference between the patients and controls. Regarding the APRI distribution, we also found a statistically significant variation between the research groups. When we compared the validity of APRI scores in diagnosing cirrhosis, we discovered that the ideal cutoff value of APRI was determined to be 3.99, with sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of 33%, 86%, 70%, and 56%, respectively. The area under the receiver operating characteristic (ROC) curve for APRI in detecting cirrhosis was also 0.693. Conclusion Thus, our study results conclude that APRI is a crucial noninvasive prognostic tool that can be utilized to prognostize liver cirrhosis.

Abstract
In 2022, the World Health Organization (WHO) estimated that hepatitis B virus (HBV) infections caused 1.5 million deaths, mostly attributable to complications from chronic infections, cirrhosis and hepatocellular carcinoma (HCC). Despite the availability of a vaccine, 296 million people were chronically infected in 2019. Asia and Africa are the continents most affected by this infection, with around 100 million people infected in Africa as a whole.Hepatitis Delta or D virus (HDV), which is a "satellite" virus of HBV, is often misunderstood and its diagnosis remains neglected. However, it is associated with acute fulminant forms and chronic forms of hepatitis leading to a more rapid evolution towards cirrhosis and HCC than during HBV mono-infection. Research on these two viruses HBV and HDV has progressed a lot in recent years, and new treatments are currently in development.In people living with the human immunodeficiency virus (PlHIV), liver disease is a major cause of morbidity and mortality. Due to common modes of transmission, dual or triple HIV/HBV or HIV/HBV/HDV infections are relatively common, particularly in HBV endemic regions such as Africa. However, while today most co-infected patients benefit from effective treatment against both HIV and HBV, the latter is not active against HDV. In Africa, hepatitis B and D have already been the subject of several studies. However, the frequency and clinical consequences of these co-infections have been little studied in the general population and in PlHIV.This review seeks to update the epidemiological and clinical data and the therapeutic perspectives of HDV co-infections or triple infections (HIV-HBV-HDV) in Africa.

J Clin Med 2023; 12:7552. [PMID: 38137620 PMCID: PMC10743606 DOI: 10.3390/jcm12247552] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Revised: 11/29/2023] [Accepted: 12/04/2023] [Indexed: 12/24/2023] Open
Abstract
The aim of this study was to evaluate the diagnostic usefulness of two non-invasive, validated, and patented markers of liver fibrosis, the Hepascore and FibroTest, in patients with primary sclerosing cholangitis (PSC). The study group consisted of 74 PSC patients and 38 healthy subjects. All patients had a liver biopsy. The Hepascore and FibroTest were calculated using specific algorithms. The ANOVA rank Kruskal-Wallis test revealed differences in the Hepascore and FibroTest between patients divided according to histological stage (p < 0.001 for both comparisons). The Hepascore and FibroTest had significantly higher results in patients with significant fibrosis (F ≥ 2) in comparison to those with no significant fibrosis (F1) (p < 0.001 for both tests) and higher values in patients with cirrhosis (F4) when compared to those without cirrhosis (F1-F3) (p < 0.001 for both comparisons). The Hepascore test showed a diagnostic sensitivity of 96.8%, a specificity of 100% for fibrosis (at cut-off 0.52) and a diagnostic sensitivity of 95.2%, and a specificity also of 100% for cirrhosis (at 0.80). The FibroTest in point 0.51 for the diagnosis of fibrosis obtained the following values: 58.6%, 90%, 89.5%, and 60%, respectively, and in point 0.73 for the diagnosis of cirrhosis: 42.9%, 100%, 100%, and 45.5, respectively. The Hepascore test reached an excellent diagnostic power in identifying both fibrosis and cirrhosis (AUC = 1.0). The FibroTest and Hepascore are highly valuable for the evaluation of the severity of liver fibrosis and cirrhosis in PSC patients and can be used as a primary screening method, allowing for a significant reduction in the need for liver biopsy. Both markers have the required sensitivity and specificity to detect liver fibrosis and cirrhosis and can be equally used in clinical practice, although the Hepascore seems to be a better test because it is more specific.

Abstract
Recently, prevalence of hepatitis B virus (HBV), and hepatitis C virus (HCV) co-infection with Human immunodeficiency virus (HIV), has dramatically increased worldwide due to their shared routes of transmission. Compared to the sporadic infection with HIV, HBV, and HCV, concurrent infection with these agents increases the complications of these viruses. Furthermore, co-infection may also alter the therapeutic strategies against HIV. Accordingly, choosing appropriate biomarkers to detect these co-infections is one of the main concerns in the field of diagnostic pathology. Up to now, several markers have been introduced for the simultaneous diagnosis of HIV, HBV, and HCV. In this regard, serum adenosine deaminase activity (ADA), FibroTests, AST-to-Platelet Ratio Index (APRI), Fibrosis-4, Hyaluronic acid, and micro ribonucleic acids (MiR) have been investigated as potential biomarkers for diagnosis of HIV-HCV/HBV co-infections. This review summarizes diagnostic values of the current and emerging biomarkers in HIV patients concurrently infected with HBV and HCV.

Abstract
In the last 20 years, noninvasive serum biomarkers to identify liver fibrosis in patients with non-alcoholic fatty liver disease (NAFLD) have been developed, validated against liver biopsy (the gold standard for determining the presence of liver fibrosis) and made available for clinicians to use to identify ≥F3 liver fibrosis. The aim of this review is firstly to focus on the current use of widely available biomarkers and their performance for identifying ≥F3. Secondly, we discuss whether noninvasive biomarkers have a role in identifying F2, a stage of fibrosis that is now known to be a risk factor for cirrhosis and overall mortality. We also consider whether machine learning algorithms offer a better alternative for identifying individuals with ≥F2 fibrosis. Thirdly, we summarise the utility of noninvasive serum biomarkers for predicting liver related outcomes (e.g., ascites and hepatocellular carcinoma) and non-liver related outcomes (e.g., cardiovascular-related mortality and extra hepatic cancers). Finally, we examine whether serial measurement of biomarkers can be used to monitor liver disease, and whether the use of noninvasive biomarkers in drug trials for non-alcoholic steatohepatitis can accurately, compared to liver histology, monitor liver fibrosis progression/regression. We conclude by offering our perspective on the future of serum biomarkers for the detection and monitoring of liver fibrosis in NAFLD.

Abstract
Background Ataxia-telangiectasia (A-T) is a rare autosomal-recessive multisystem disorder characterized by pronounced cerebellar ataxia, telangiectasia, cancer predisposition, and altered body composition. Liver diseases with steatosis, fibrosis, and hepatocellular carcinoma are frequent findings in older patients but sensitive noninvasive diagnostic tools are lacking. Objectives To determine the sensitivity of transient elastography (TE) as a screening tool for early hepatic tissue changes and serum biomarkers for liver disease. Methods Thirty-one A-T patients aged 2 to 25 years were examined prospectively from 2016-2018 by TE. In addition, we evaluated the diagnostic performance of liver biomarkers for steatosis and necroinflammatory activity (SteatoTest and ActiTest, Biopredictive, Paris) compared to TE. For calculation and comparison, patients were divided into two groups (<12, >12 years of age). Results TE revealed steatosis in 2/21 (10%) younger patients compared to 9/10 (90%) older patients. Fibrosis was present in 3/10 (30%) older patients as assessed by TE. We found a significant correlation of steatosis with SteatoTest, alpha-fetoprotein (AFP), HbA1c, and triglycerides. Liver stiffness correlated significantly with SteatoTest, ActiTest, HbA1c, and triglycerides. Conclusion Liver disease is a common finding in older A-T patients. TE is an objective measure to detect early stages of steatosis and fibrosis. SteatoTest and ActiTest are a good diagnostic assessment for steatosis and necroinflammatory activity in patients with A-T and confirmed the TE results.

Abstract
Approximately 30% of the worldwide population has at least one risk factor for liver disease. Identifying advanced liver disease before the occurrence of complications remains a difficult challenge in clinical practice, where diagnosis comes too late for many patients, at the time of liver decompensation or palliative hepatocellular carcinoma, with poor short-term prognosis. Noninvasive, blood- or elastography-based tests of liver fibrosis (NITs) have been developed for the early diagnosis of advanced liver fibrosis. Recent population-based studies evaluating the screening of liver fibrosis with these NITs have provided important information on at-risk groups that should be targeted. New measures based on the sequential use of NITs help to better organize the referral of at-risk patients to the liver specialist. However, energizing these measures will require increased awareness of both chronic liver diseases and the use of NITs among non-specialists.

Abstract
BACKGROUND Direct-acting antiviral (DAA) regimens and telemedicine services are both options for treating hepatitis C virus (HCV) within the prison setting. We aimed to compare factors associated with HCV treatment success over the past decade in Israeli prisons, specifically the influence of DAAs and telemedicine. METHODS We retrospectively reviewed the medical records of inmates with HCV infection in Israeli prisons from 2010 through 2020. Demographic, clinical, and laboratory data were recorded, including treatment regimens and success rates. RESULTS A total of 273 inmates were treated; mean age 45 ± 9.36 years; 98.2% males; 63.9% with a history of drug abuse. Advanced fibrosis was documented in 42.9%. The most common genotypes were 1 (46%) followed by 3 (40.7%). Interferon-based regimens were given to 68 inmates between 2010 and 2017. DAA agents were introduced in 2016, with pan-genotype regimens being exclusively used since 2019. Telemedicine services were used in 140 patients (51.3%), starting in February 2019. The sustained viral response (SVR) rate with interferon-based therapy was 78.8% and 98.8% with DAA treatment, giving an overall SVR of 93.2%. This difference between regimens proved to be the only statistically significant predictor of treatment success. The number of prisoners being treated with DAAs increased exponentially after telemedicine was introduced. Comparable SVR rates were achieved with either in-person or telemedicine consultation. CONCLUSION Screening of this high-risk population and using telemedicine for treatment may be an effective strategy for the elimination of HCV from the prison population.

Abstract
BACKGROUND & AIMS Noninvasive tests (NITs) of liver fibrosis have been suggested to be less accurate in type 2 diabetes mellitus (T2DM). We aimed to compare the accuracy of 6 NITs between patients with or without T2DM, explain any differences, and adapt diagnostic algorithms for clinical practice accordingly. METHODS We included 1051 patients with nonalcoholic fatty liver disease with liver biopsy, blood fibrosis tests (Nonalcoholic Fatty Liver Disease Fibrosis Score, FIB4, Fibrotest, FibroMeter), vibration-controlled transient elastography (VCTE), and the combinatory elasto-blood test FibroMeterVCTE. The study endpoint was advanced fibrosis on liver biopsy. RESULTS NIT areas under the receiver operating characteristic curve were significantly lower in patients with T2DM, mostly because of a decrease in specificity. For FIB4, this decrease in specificity was only related to the higher age of patients with T2DM enrolled. For Fibrotest, FibroMeter, and FibroMeterVCTE, the decrease in specificity was related to age but also to higher alpha2-macroglobulin level, which is known to increase in T2DM. Sensitivity was unaffected by T2DM, but it masked a doubled raw number of false negatives because of the 2-fold higher prevalence of advanced fibrosis in that setting. The sequential algorithm FIB4-vibration-controlled transient elastography had 90.3% accuracy in patients without T2DM vs 79.0% in those with (P < .001). Algorithms using first-line specialized tests maintained a low rate of false negatives and false positives in T2DM. CONCLUSIONS The decrease in NIT accuracy observed in T2DM is partly biased by the different characteristics of the groups studied, but also linked to T2DM itself through modification of the levels of some NIT biomarkers. Specialized tests should be used first-line to diagnose advanced liver fibrosis in T2DM.

Diagnostic Modalities of Non-Alcoholic Fatty Liver Disease: From Biochemical Biomarkers to Multi-Omics Non-Invasive Approaches. Diagnostics (Basel) 2022; 12:diagnostics12020407. [PMID: 35204498 PMCID: PMC8871470 DOI: 10.3390/diagnostics12020407] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2021] [Revised: 01/31/2022] [Accepted: 02/02/2022] [Indexed: 02/05/2023] Open
Abstract
Non-Alcoholic Fatty Liver Disease (NAFLD) is currently the most common cause of chronic liver disease worldwide, and its prevalence is increasing globally. NAFLD is a multifaceted disorder, and its spectrum includes steatosis to steatohepatitis, which may evolve to advanced fibrosis and cirrhosis. In addition, the presence of NAFLD is independently associated with a higher cardiometabolic risk and increased mortality rates. Considering that the vast majority of individuals with NAFLD are mainly asymptomatic, early diagnosis of non-alcoholic steatohepatitis (NASH) and accurate staging of fibrosis risk is crucial for better stratification, monitoring and targeted management of patients at risk. To date, liver biopsy remains the gold standard procedure for the diagnosis of NASH and staging of NAFLD. However, due to its invasive nature, research on non-invasive tests is rapidly increasing with significant advances having been achieved during the last decades in the diagnostic field. New promising non-invasive biomarkers and techniques have been developed, evaluated and assessed, including biochemical markers, imaging modalities and the most recent multi-omics approaches. Our article provides a comprehensive review of the currently available and emerging non-invasive diagnostic tools used in assessing NAFLD, also highlighting the importance of accurate and validated diagnostic tools.

Non-invasive diagnosis and follow-up of non-alcoholic fatty liver disease. Clin Res Hepatol Gastroenterol 2022; 46:101769. [PMID: 34332133 DOI: 10.1016/j.clinre.2021.101769] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/11/2021] [Accepted: 07/23/2021] [Indexed: 02/04/2023]
Abstract
NAFLD is a frequent disease that affects 25% of the worldwide population. There is no specific diagnostic test for NAFLD, and the diagnosis mainly relies on the elimination of the other causes of chronic liver diseases with liver biopsy kept for unsure diagnoses. Non-invasive tests are now available to assess NAFLD severity and therefore to help physicians decide on the patient management and follow-up. These non-invasive tests can also be used to define pathways that organize referrals from primary care and diabetology clinics to the liver specialist, with the ambition to improve the screening of asymptomatic patients with NAFLD and advanced liver disease. NAFLD being the liver expression of the metabolic syndrome, physicians need also take care to screen for diabetes and to evaluate the cardiovascular risk in those patients. These recommendations from the French Association for the Study of the Liver (AFEF) aim at providing guidance on the following questions: how to diagnose NAFLD; how non-invasive tests should be used to assess NAFLD severity; how to follow patients with NAFLD; when to perform liver biopsy in NAFLD; and how to decide referral to the liver specialist for a patient with NAFLD.

Abstract
BACKGROUND Nonalcoholic fatty liver disease (NAFLD) is associated with substantial morbidity, mortality, and economic burden. With currently no approved treatment, an effective pharmaceutical intervention for this disease must be both clinically- and cost-effective. METHODS A Markov model was constructed to estimate the clinical outcomes, costs, and quality of life impact of a hypothetical pharmaceutical intervention. Lifetime clinical outcomes, life-years, quality-adjusted life-years (QALYs), costs (2020 $US), incremental cost-effectiveness ratios (ICERs), and economically justifiable prices (EJPs) were quantified. Only patients with fibrosis stage F2-F4 were assumed eligible to initiate pharmaceutical treatment. RESULTS Over a mean life expectancy of approximately 21 years in the simulated cohort, drug treatment reduced liver-related mortality by 6.0% (2.7% absolute reduction). Assuming an annual drug cost of $36,000, total discounted medical costs were $574,238 and $120,312 for drug and usual care, respectively, with discounted QALYs estimated to be 9.452 and 9.272 for the two comparators. This yielded an ICER of $2,517,676/QALY gained. The EJP of the drug at an ICER threshold of $150,000/QALY gained was $2,633, a 93% reduction from a base case. Sensitivity analyses suggest that, without a substantial decrease in the drug price, ICERs would exceed $500,000/QALY gained even with the most favorable efficacy assumptions. CONCLUSIONS For a pharmaceutical intervention to be considered cost-effective in the NAFLD fibrosis population, the substantial clinical benefit will need to be coupled with a modest annual price. Annual drug costs exceeding $12,000 likely will not provide reasonable value, even with favorable efficacy. More work is needed to estimate the cost-effectiveness of lifestyle modifications.

Abstract
Hepatitis B virus is a small enveloped RNA virus, which replicates independently but requires the hepatitis B virus (HBV) to provide the envelope proteins necessary for the assembly of its own viral particles. Approximately 5% of chronic hepatitis B virus carriers are infected with HDV. HBV vaccination remains the best preventive treatment for HDV. All HBV patients should be screened for HDV (anti-HDV serology). In case of positive HDV serology, HDV replication (HDV RNA) should be investigated using a sensitive and specific technique. Hepatitis Delta is often complicated by cirrhosis and hepatocellular carcinoma (HCC). For this reason, every patient with Delta cirrhosis should be screened for HCC by abdominal ultrasound every 6 months. The historical treatment was based on PEG-IFN with many side effects. A new treatment has been approved, Bulevirtide (Hepcludex®) an HDV/HBV entry inhibitor, for any patient with chronic hepatitis Delta infection (CHD) with active replication (except in decompensated cirrhosis), at a dose of 2mg/day by subcutaneous injection. The exact duration on-treatment is unknown, thus treatment should be continued if clinical benefit is observed.

Abstract
Hepatitis C virus infection affects 71 million people worldwide. It is at the origin of a multi-organ disease associating hepatic manifestations, cryoglobulinemic vasculitis and general manifestations linked to chronic inflammation (diabetes, cardio-, reno- or cerebrovascular manifestations, extra-hepatic cancers including non-Hodgkin's lymphoma). The significant morbidity and mortality linked to the hepatitis C virus therefore justify its screening and access to treatments which have increased considerably over the past two decades. Understanding the replicative cycle of the hepatitis C virus has enabled the development of direct HCV-specific antivirals targeting viral proteins (NS3/4A protease, NS5B polymerase and the multifunctional NS5A replication complex). The combination of two to three specific inhibitors often co-formulated in a capsule, without pegylated interferon and most often without ribavirin, allows high antiviral efficacy (more than 97% cure) for a treatment duration of 8-12 weeks with satisfactory tolerance. HCV infection is the only chronic viral infection that can be cured and the hepatic or extrahepatic manifestations are mainly reversible. This underlines the importance of strengthening screening and access to care policies in order to achieve the elimination of viral infection C in the short term, in 2030, as expected from the program of the World Health Organization. If this elimination is possible in some countries (Iceland, France, Germany …), it seems compromised in others where prevention (USA), screening and/or access to care are still insufficient (Sub-Saharan Africa, Russia…).

Abstract
BACKGROUND Urea cycle disorders (UCDs) are among the most common inborn errors of liver metabolism. As therapies for hyperammonemia associated with urea cycle dysfunction have improved, chronic complications, such as liver disease, have become increasingly apparent in individuals with UCDs. Liver disease in UCDs may be associated with hepatic inflammation, hepatic fibrosis, portal hypertension, liver cancer and even liver failure. However, except for monitoring serum aminotransferases, there are no clear guidelines for screening and/or monitoring individuals with UCDs for liver disease. Thus, we systematically evaluated the potential utility of several non-invasive biomarkers for liver fibrosis in UCDs. METHODS We evaluated grey-scale ultrasonography, liver stiffness obtained from shear wave elastography (SWE), and various serum biomarkers for hepatic fibrosis and necroinflammation, in a cohort of 28 children and adults with various UCDs. RESULTS Overall, we demonstrate a high burden of liver disease in our participants with 46% of participants having abnormal grey-scale ultrasound pattern of the liver parenchyma, and 52% of individuals having increased liver stiffness. The analysis of serum biomarkers revealed that 32% of participants had elevated FibroTest™ score, a marker for hepatic fibrosis, and 25% of participants had increased ActiTest™ score, a marker for necroinflammation. Interestingly, liver stiffness did not correlate with ultrasound appearance or FibroTest™. CONCLUSION Overall, our results demonstrate the high overall burden of liver disease in UCDs and highlights the need for further studies exploring new tools for identifying and monitoring individuals with UCDs who are at risk for this complication. TRIAL REGISTRATION This study has been registered in ClinicalTrials.gov (NCT03721367).

FibroTest for Evaluating Fibrosis in Non-Alcoholic Fatty Liver Disease Patients: A Systematic Review and Meta-Analysis. J Clin Med 2021; 10:jcm10112415. [PMID: 34072480 PMCID: PMC8198930 DOI: 10.3390/jcm10112415] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2021] [Revised: 05/23/2021] [Accepted: 05/25/2021] [Indexed: 12/12/2022] Open
Abstract
(1) Background: FibroTest™ is a multi-marker panel, suggested by guidelines as one of the surrogate markers with acceptable performance for detecting fibrosis in patients with non-alcoholic fatty liver disease (NAFLD). A number of studies evaluating this test have been published after publication of the guidelines. This study aims to produce summary estimates of FibroTest™ diagnostic accuracy. (2) Methods: Five databases were searched for studies that evaluated FibroTest™ against liver biopsy as the reference standard in NAFLD patients. Two authors independently screened the references, extracted data, and assessed the quality of included studies. Meta-analyses of the accuracy in detecting different levels of fibrosis were performed using the bivariate random-effects model and the linear mixed-effects multiple thresholds model. (3) Results: From ten included studies, seven were eligible for inclusion in our meta-analysis. Five studies were included in the meta-analysis of FibroTest™ in detecting advanced fibrosis and five in significant fibrosis, resulting in an AUC of 0.77 for both target conditions. The meta-analysis of three studies resulted in an AUC of 0.69 in detecting any fibrosis, while analysis of three other studies showed higher accuracy in cirrhosis (AUC: 0.92). (4) Conclusions: Our meta-analysis showed acceptable performance (AUC > 0.80) of FibroTest™ only in detecting cirrhosis. We observed more limited performance of the test in detecting significant and advanced fibrosis in NAFLD patients. Further primary studies with high methodological quality are required to validate the reliability of the test for detecting different fibrosis levels and to compare the performance of the test in different settings.

Abstract
To investigate the long-term prognosis of liver disease in patients with hepatitis C virus (HCV) eradication after antiviral therapy versus those with persistent HCV infection. Four hundred and eighty patients (5259 person-years [PYs]) who received interferon-based therapy and achieved sustained virologic response and 848 patients (3853 PYs) with persistent HCV infection were included. In the analysis of 1-year liver disease state transition probability matrices using Markov chain models, progression to cirrhosis from the chronic hepatitis state was observed (0.00%-0.63%) in patients with HCV eradication. Among patients with chronic hepatitis or cirrhosis and HCV eradication, hepatocellular carcinoma (HCC) development was observed in males aged ≥ 50 years (0.97%-1.96%) and females aged ≥ 60 years (0.26%-5.00%). Additionally, in patients with cirrhosis and HCV eradication, improvement to chronic hepatitis was also observed (4.94%-10.64%). Conversely, in patients with chronic hepatitis and persistent HCV infection, progression to cirrhosis was observed in males aged ≥ 30 years and female aged ≥ 40 years (0.44%-1.99%). In males aged ≥ 40 years and female aged ≥ 50 years with cirrhosis, the transition probability for HCC was relatively high (4.17%-14.02%). Under the assumption of either chronic hepatitis or cirrhosis at age 40 or 60 years as the starting condition for simulation over the next 30 or 40 years, respectively, the probability of HCC was higher in patients with persistent HCV infection than those with HCV eradication. In conclusion, HCV eradication can reduce the risk of developing cirrhosis or HCC in patients with chronic HCV infection.

Abstract
There are limited data available on the regression of fibrosis in hepatitis C virus (HCV) patients who have achieved sustained virologic response (SVR) after interferon-free treatments. Moreover, a perfect method for assessing liver fibrosis and its dynamics has not been established yet. The main objective of this study was to evaluate the dynamics of aspartate aminotransferase to platelet ratio index (APRI) and Fibrosis-4 (FIB-4) scores in patients with HCV who registered SVR. We performed ROC curve analysis to evaluate the diagnostic performance of APRI and FIB-4 scores in determining the presence of cirrhosis in comparison to FibroTest. In total 251 patients were enrolled: 164 cirrhotic and 83 non-cirrhotic patients, and they were evaluated at baseline, at 6 and at 12 months post-end of treatment (EOT). In the cirrhotic group, at baseline, there was a weak but statistically significant correlation between APRI and FibroTest (τ=0.173, P=0.001), as well as between FIB-4 and FibroTest (τ=0.265, P<0.001). At the 6-month follow-up, APRI no longer correlated with FibroTest (τ=0.144, P=0.057), while FIB-4 was correlated (τ=0.256, P=0.001). The same pattern was shown at 12 months post-EOT. Between baseline and the 6-month evaluation, there was a significant decrease in APRI (P<0.001) and FIB-4 (P<0.001) scores, but for the next follow-up period, there was no reduction. In the non-cirrhotic group, APRI and FIB-4 did not correlate with the FibroTest value at any of the evaluation times. There was a significant difference between baseline and the 6-month visit for APRI (P=0.01) and for FIB-4 (P=0.014). The areas under the receiver operating characteristics curve (AUROCs) for the presence of cirrhosis compared with FibroTest for APRI and FIB-4 were 0.682 [95% confidence interval (CI), 0.613-0.752] and 0.693 (95% CI 0.625-0.76). Both APRI and FIB-4 prove to be easy, quick and inexpensive tools for screening HCV cirrhosis, with moderate diagnostic accuracy and FIB-4 can be useful for monitoring patients post-EOT.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronically elevated liver enzymes. Diagnosis and risk stratification of NAFLD remains clinically challenge as patients with NAFLD are either asymptomatic or have nonspecific presenting complaints and may have normal liver enzymes. Nonalcoholic steatohepatitis (NASH), the clinically aggressive variant of NAFLD, is also difficult to differentiate noninvasively, and a liver biopsy is required to definitively diagnose NASH. Thus, the definitive diagnosis and risk stratification of NAFLD is embedded in histological assessment of the liver. Several clinical aides been investigated in an attempt to risk stratify and identify patients noninvasively as doing a liver biopsy in all patients with NAFLD are not feasible. Since these biomarkers are unable to differentiate NASH from non-NASH, they have leveraged biochemical changes within the liver as patients progress to varying degree of hepatic fibrosis to identify patients with moderate fibrosis (fibrosis stage 2 or greater) and advanced fibrosis (fibrosis stage 3 or greater) to help guide the need for additional and more definitive workup. These clinical aides span from by-products of apoptosis to statistical modelling of clinically available data to identify 'at-risk' patients with NAFLD. The current review will focus the diagnostic performance of these noninvasive serum-based biomarkers in NAFLD.

Long-term prognosis of liver disease in patients with eradicated chronic hepatitis C virus: An analysis using a Markov chain model. Hepatol Res 2020; 50:936-946.

Abstract
AIM The long-term prognosis of patients with chronic hepatitis C virus (HCV) infection who have received antiviral therapy and who demonstrate HCV eradication remains incompletely characterized. In this study, we investigated the long-term prognosis of liver disease in patients with eradication of HCV. METHODS A total of 552 patients with chronic HCV infection (6815 person-years) who were treated with interferon-based therapy and who achieved sustained virologic response were included. Yearly transition probabilities for each liver state (chronic hepatitis, cirrhosis, and hepatocellular carcinoma [HCC]) were calculated using a Markov chain model. RESULTS In the analysis of 1-year liver disease state transition probabilities, progression to cirrhosis occurred in 0.5-2.1% of male patients with chronic hepatitis across all age groups. In male patients with cirrhosis, HCC developed in 0.6-1.9% of patients over the age of 50 years. In female patients with chronic hepatitis, progression to cirrhosis occurred in 0.4-2.1% of patients across all age groups. In addition, in female patients with cirrhosis, HCC developed in those aged 60-69 (0.4%) and 70-79 (0.4%) years. Under the assumption of either a chronic hepatitis or cirrhosis state at age 40 or 60 years as the starting condition for simulation over the next 40 or 20 years, respectively, the probability of HCC gradually increased with age and was higher in male patients. CONCLUSIONS The development or progression of cirrhosis and the development of HCC are risks in HCV patients despite HCV eradication, not only in those with cirrhosis but also in those with chronic hepatitis.

Abstract
Background and Aims: Liver biopsy remains the gold standard for staging of chronic liver disease following orthotopic liver transplantation. Noninvasive assessment of fibrosis with Fibro-test (FT) is well-studied in immunocompetent populations with chronic hepatitis C virus infection. The aim of this study is to investigate the diagnostic value of FT in the assessment of hepatic fibrosis in the allografts of liver transplant recipients with evidence of recurrent hepatitis C. Methods: We retrospectively compared liver biopsies and FT performed within a median of 1 month of each other in orthotopic liver transplantation recipients with recurrent hepatitis C. Results: The study population comprised 22 patients, most of them male (19/22), and with median age of 62 years. For all patients, there was at least a one-stage difference in fibrosis as assessed by liver biopsy compared to FT, while for the majority (16/22) there was at least a two-stage difference. The absence of correlation between the two modalities was statistically demonstrated (Mann-Whitney U test, p = 0.01). In detecting significant fibrosis (a METAVIR stage of F2 and above), an FT cut-off of 0.5 showed moderate sensitivity (77%) and negative predictive value (80%), but suboptimal specificity (61%) and positive predictive value (58%). Conclusions: In post-transplant patients with recurrent hepatitis C, FT appears to be inaccurately assessing the degree of allograft fibrosis, therefore limiting its reliability as a staging tool.

Abstract
Cirrhosis is characterized by extensive hepatic fibrosis, and it is the 14th leading cause of death worldwide. Numerous contributing conditions have been implicated in its development, including infectious etiologies, medication overdose or adverse effects, ingestible toxins, autoimmunity, hemochromatosis, Wilson’s disease and primary biliary cholangitis to list a few. It is associated with portal hypertension and its stigmata (varices, ascites, hepatic encephalopathy, combined coagulopathy and thrombophilia), and it is a major risk factor for hepatocellular carcinoma. Currently, orthotopic liver transplantation has been the only curative modality to treat cirrhosis, and the scarcity of donors results in many people waiting years for a transplant. Identification of novel targets for pharmacologic therapy through elucidation of key mechanistic components to induce fibrosis reversal is the subject of intense research. Development of robust models of hepatic fibrosis to faithfully characterize the interplay between activated hepatic stellate cells (the principal fibrogenic contributor to fibrosis initiation and perpetuation), hepatocytes and extracellular matrix components has the potential to identify critical components and mechanisms that can be exploited for targeted treatment. In this review, we will highlight key cellular pathways involved in the pathophysiology of fibrosis from extracellular ligands, effectors and receptors, to nuclear receptors, epigenetic mechanisms, energy homeostasis and cytokines. Further, molecular pathways of hepatic stellate cell deactivation are discussed, including apoptosis, senescence and reversal or transdifferentiation to an inactivated state resembling quiescence. Lastly, clinical evidence of fibrosis reversal induced by biologics and small molecules is summarized, current compounds under clinical trials are described and efforts for treatment of hepatic fibrosis with mesenchymal stem cells are highlighted. An enhanced understanding of the rich tapestry of cellular processes identified in the initiation, perpetuation and resolution of hepatic fibrosis, driven principally through phenotypic switching of hepatic stellate cells, should lead to a breakthrough in potential therapeutic modalities.

Abstract
The infection with the hepatitis C virus (HCV) is an example of the translational research success. The reciprocal interactions between clinicians and scientists have allowed in 30 years the initiation of empirical treatments by interferon, the discovery of the virus, the development of serological and virological tools for diagnosis but also for prognosis (the non-invasive biochemical or morphological fibrosis tests, the predictors of the specific immune response including genetic IL28B polymorphisms). Finally, well-tolerated and effective treatments with oral antivirals inhibiting HCV non-structural viral proteins involved in viral replication have been marketed this last decade, allowing the cure of all infected subjects. HCV chronic infection, which is a public health issue, is a hepatic disease which may lead to a cirrhosis and an hepatocellular carcinoma (HCC) but also a systemic disease with extra-hepatic manifestations either associated with a cryoglobulinemic vasculitis or chronic inflammation. The HCV infection is the only chronic viral infection which may be cured: the so-called sustained virologic response, defined by undetectable HCV RNA 12 weeks after the end of the treatment, significantly reduces the risk of morbidity and mortality associated with hepatic and extra-hepatic manifestations which are mainly reversible. The history of HCV ends with the pangenotypic efficacy of the multiple combinations, easy to use for 8-12 weeks with one to three pills per day and little problems of tolerance. This explains the short 30 years from the virus discovery to the viral hepatitis elimination policy proposed by the World Health Organization (WHO) in 2016.

Abstract
All chronic liver disease can lead to liver fibrosis. Assessment of the severity of liver fibrosis is central to making treatment and management decisions. Liver biopsy, the gold standard for liver fibrosis assessment, is invasive and carries risks of complications and sampling errors. The use of noninvasive elastography-based radiologic methods of liver fibrosis determination is limited to centers that have the capabilities. Laboratory liver fibrosis determinations, both general clinical scoring systems and combination biomarker panels, are accessible to a wider population of clinicians for identifying patients at low risk of advanced fibrosis who do not need liver biopsies.

Abstract
BACKGROUND Fibrosis regression has been associated with nucleoside analogue (NA) treatment in chronic hepatitis B (CHB) patients. Although non-invasive fibrosis markers have been evaluated in CHB, their utility for monitoring on-treatment histologic regression has not been evaluated. AIMS To characterize improvements in disease severity and the utility of non-invasive biomarkers in CHB NA treated patients. METHODS Histology, labs, AST-to-platelet ratio index, and Fibrosis-4 (Fib-4) from treatment-naïve CHB patients were evaluated at baseline and longitudinally. Relative change from baseline to various time points during treatment were evaluated. Correlative analysis of APRI and Fib-4 with histology was performed longitudinally. RESULTS 80 CHB patients (84% male, median age 45 (IQR 32, 54)) with histology up to 17 years (median 6(IQR 3.9, 8.0)) years were studied. Median baseline Ishak fibrosis was 3 (IQR 2, 4), histologic activity index (HAI) inflammation was 9 (IQR 7, 11), and AUROC of fibrosis markers for detecting cirrhosis (Ishak ≥ 5) was >0.64. HAI improved at a rate of 54% during year 1 and 37% in year 2, both greater than in the remaining follow-up periods. Within the first year, fibrosis improved by 35%, greater than all other time periods. Non-invasive biomarkers began to correlate with histology beyond 4 years (APRI: 4-6 years: r = 0.33, p = 0.03; ≥6 years: r = 0.41, p = 0.009; Fib-4: ≥6 years: r = 0.35, p = 0.03). CONCLUSION Early dynamic changes in histology occur in CHB patients on NA followed by linear improvements. Non-invasive fibrosis biomarkers do not capture these dynamic changes and may demonstrate clinical utility beyond 4 years of treatment.

Abstract
Background: The prevalence of morbidity and mortality associated with liver disease among HIV-infected individuals on combination antiretroviral therapy (ART) is high. Early screening of liver disease is essential, as it provides an opportunity for successful treatment. Hence, there is a need for reliable, inexpensive and non-invasive early markers of hepatic damage.Objectives: Non-invasive algorithms are available for assessing the extent of liver fibrosis as markers of ongoing inflammatory damage. This study compared the use of the FibroTest, Fibrosis-4 (FIB-4) index, APRI test and AST:ALT ratio in assessing liver fibrosis in combination ART-experienced individuals.Methods: In a comparative cross-sectional study, 79 participants between the ages of 8 and 62 years were recruited. The performance of each fibrosis algorithm was determined using established cut-off scores for clinically significant liver fibrosis.Results: The prevalence of liver fibrosis as determined by the FibroTest, FIB-4 index, APRI test and AST: ALT ratio were 19.0%, 21.5%, 12.7% and 79.7%, respectively. For individual biomarkers, A-2M concentration (p < 0.001) and AST activity (p = 0.003) remained significantly elevated in participants with fibrosis than those without as defined by FibroTest and APRI test, respectively, after adjustments for multiple comparisons.Conclusion: Our data demonstrate a high prevalence of asymptomatic liver fibrosis among combination ART-experienced individuals in Zimbabwe, and this warrants adequate monitoring of liver fibrosis in individuals on ART. Discordance of fibrosis results among the algorithms and individual biomarkers and calls for further work in identifying optimal biomarkers for detection of asymptomatic fibrosis.Keywords: Liver fibrosis; Non-invasive methods; Biomarkers; Combination anti-retroviral therapy; Zimbabwe.

The Epidemiology, Risk Profiling and Diagnostic Challenges of Nonalcoholic Fatty Liver Disease. MEDICINES 2019; 6:medicines6010041.

Abstract
Nonalcoholic fatty liver disease (NAFLD) encompasses a wide spectrum of liver damage from the more prevalent (75%⁻80%) and nonprogressive nonalcoholic fatty liver (NAFL) category to its less common and more ominous subset, nonalcoholic steatohepatitis (NASH). NAFLD is now the most common cause of chronic liver disease in the developed world and is a leading indication for liver transplantation in United States (US). The global prevalence of NAFLD is estimated to be 25%, with the lowest prevalence in Africa (13.5%) and highest in the Middle East (31.8%) and South America (30.4%). The increasing incidence of NAFLD has been associated with the global obesity epidemic and manifestation of metabolic complications, including hypertension, diabetes, and dyslipidemia. The rapidly rising healthcare and economic burdens of NAFLD warrant institution of preventative and treatment measures in the high-risk sub-populations in an effort to reduce the morbidity and mortality associated with NAFLD. Genetic, demographic, clinical, and environmental factors may play a role in the pathogenesis of NAFLD. While NAFLD has been linked with various genetic variants, including PNPLA-3, TM6SF2, and FDFT1, environmental factors may predispose individuals to NAFLD as well. NAFLD is more common in older age groups and in men. With regards to ethnicity, in the US, Hispanics have the highest prevalence of NAFLD, followed by Caucasians and then African-Americans. NAFLD is frequently associated with the components of metabolic syndrome, such as type 2 diabetes mellitus (T2DM), obesity, hypertension, and dyslipidemia. Several studies have shown that the adoption of a healthy lifestyle, weight loss, and pro-active management of individual components of metabolic syndrome can help to prevent, retard or reverse NAFLD-related liver damage. Independently, NAFLD increases the risk of premature cardiovascular disease and associated mortality. For this reason, a case can be made for screening of NAFLD to facilitate early diagnosis and to prevent the hepatic and extra-hepatic complications in high risk sub-populations with morbid obesity, diabetes, and other metabolic risk factors.

Abstract
BACKGROUND & AIMS Non-invasive tools for monitoring treatment response and disease progression in non-alcoholic steatohepatitis (NASH) are needed. Our objective was to evaluate the utility of magnetic resonance (MR)-based hepatic imaging measures for the assessment of liver histology in patients with NASH. METHODS We analyzed data from patients with NASH and stage 2 or 3 fibrosis enrolled in a phase II study of selonsertib. Pre- and post-treatment assessments included centrally read MR elastography (MRE)-estimated liver stiffness, MR imaging-estimated proton density fat fraction (MRI-PDFF), and liver biopsies evaluated according to the NASH Clinical Research Network classification and the non-alcoholic fatty liver disease activity score (NAS). RESULTS Among 54 patients with MRE and biopsies at baseline and week 24, 18 (33%) had fibrosis improvement (≥1-stage reduction) after undergoing 24 weeks of treatment with the study drug. The area under the receiver operating characteristic curve (AUROC) of MRE-stiffness to predict fibrosis improvement was 0.62 (95% CI 0.46-0.78) and the optimal threshold was a ≥0% relative reduction. At this threshold, MRE had 67% sensitivity, 64% specificity, 48% positive predictive value, 79% negative predictive value. Among 65 patients with MRI-PDFF and biopsies at baseline and week 24, a ≥1-grade reduction in steatosis was observed in 18 (28%). The AUROC of MRI-PDFF to predict steatosis response was 0.70 (95% CI 0.57-0.83) and the optimal threshold was a ≥0% relative reduction. At this threshold, MRI-PDFF had 89% sensitivity and 47% specificity, 39% positive predictive value, and 92% negative predictive value. CONCLUSIONS These preliminary data support the further evaluation of MRE-stiffness and MRI-PDFF for the longitudinal assessment of histologic response in patients with NASH. LAY SUMMARY Liver biopsy is a potentially painful and risky method to assess damage to the liver due to non-alcoholic steatohepatitis (NASH). We analyzed data from a clinical trial to determine if 2 methods of magnetic resonance imaging - 1 to measure liver fat and 1 to measure liver fibrosis (scarring) - could potentially replace liver biopsy in evaluating NASH-related liver injury. Both imaging methods were correlated with biopsy in showing the effects of NASH on the liver.

Abstract
BACKGROUND & AIMS Increased de novo lipogenesis (DNL) contributes to the pathogenesis of nonalcoholic steatohepatitis (NASH). Acetyl-CoA carboxylase catalyzes the rate-limiting step in DNL. We evaluated the safety and efficacy of GS-0976, a small molecule inhibitor of acetyl-CoA carboxylase, in patients with NASH. METHODS In an open-label prospective study, patients with NASH (n = 10) received GS-0976 20 mg orally once daily for 12 weeks. NASH was diagnosed based on a proton density fat fraction estimated by magnetic resonance imaging (MRI-PDFF) ≥10% and liver stiffness by magnetic resonance elastography (MRE) ≥2.88 kPa. The contribution from hepatic DNL to plasma palmitate was measured by 14 days of heavy water labeling before and at the end of treatment. We performed the same labelling protocol in an analysis of healthy volunteers who were not given DNL (controls, n = 10). MRI-PDFF and MRE at baseline, and at weeks 4 and 12 of GS-0976 administration, were measured. We analyzed markers of liver injury and serum markers of fibrosis. RESULTS The contribution of hepatic DNL to plasma palmitate was significantly greater in patients with NASH compared with controls (43% vs 18%) (P = .003). After 12 weeks administration of GS-0976, the median hepatic DNL was reduced 22% from baseline in patients with NASH (P = .004). Compared with baseline, reductions in MRI-PDFF at week 12 (15.7% vs 9.1% at baseline; P = .006), liver stiffness by MRE (3.4 kPa vs 3.1 kPa at baseline; P = .049), TIMP metallopeptidase inhibitor 1 (275 ng/mL vs 244 ng/mL at baseline; P = .049), and serum level of alanine aminotransferase (101 U/L vs 57 U/L at baseline; P = .23) were consistent with decreased hepatic lipid content and liver injury. At week 12, 7 patients (70%) had a ≥30% decrease in MRI-PDFF. CONCLUSION In an open-label study, patients with NASH given GS-0976 for 12 weeks had reduced hepatic DNL, steatosis, and markers of liver injury. ClinicalTrials.gov no: NCT02856555.

Abstract
OBJECTIVE As the population of patients with Fontan circulation surviving into adulthood increases, hepatic cirrhosis has grown to be a significant cause of morbidity and mortality. Early detection of advanced hepatic fibrosis is imperative for proper intervention and consideration for heart or combined heart/liver transplantation. Noninvasive biomarkers and elastography have been evaluated for their diagnostic utility with variable results in the Fontan population. DESIGN The cohort included 14 patients age 26.4 SD 7.5 who underwent Fontan surgery. All patients were evaluated with FibroSURE, shear wave elastography (SWE), hepatic duplex sonography, and liver biopsy. Liver fibrosis on biopsy was evaluated according to the congestive hepatic fibrosis system. RESULTS In our cohort, 100% of patients had fibrosis with 36% demonstrating advanced fibrosis. FibroSURE agreed with liver biopsy in only 5 out of 14 cases (36%): underestimating in 7 and overestimating in 2 individuals. SWE agreed with liver biopsy in 0% of cases: overestimating in 10 and underestimating in 4 cases. None of the duplex sonography indices predicted the presence or severity of liver fibrosis. CONCLUSION This study demonstrates that children who have undergone a Fontan procedure universally develop some hepatic fibrosis and a significant number have advanced fibrosis by adulthood. The FibroSURE blood test, SWE, and hepatic duplex sonography were unable to accurately predict the presence or severity of hepatic fibrosis when compared with liver biopsy. Further studies are needed to investigate novel noninvasive methods and/or biomarkers that can adequately detect advanced hepatic fibrosis before the development of cirrhosis and hepatic decompensation.

Abstract
BACKGROUND & OBJECTIVES One of the multiple factors contributing to virological response in chronic hepatitis C (CHC) is interferon-gamma-inducible protein-10 (IP-10). Its level reflects the status of interferon-stimulated genes, which in turn is associated with virological response to antiviral therapy. The aim of this study was to evaluate the role of serum IP-10 levels on sustained virological response (SVR) and the association of this parameter with insulin resistance (IR) and liver histology. METHODS Two hundred and three consecutive biopsy proven CHC patients were included in the study. Serum levels of IP-10 were determined using ELISA method. IR was evaluated by homeostasis model assessment-IR (HOMA-IR). Histological features were assessed invasively by liver biopsy and noninvasively using FibroTest, ActiTest and SteatoTest. Predictive factors for SVR and their interrelations were assessed. RESULTS A cut-off value for IP-10 of 392 pg/ml was obtained to discriminate between responders and non-responders. SVR was obtained in 107 patients (52.70%). Area under the receiver operating characteristic curve for SVR was 0.875 with a sensitivity of 91.6 per cent, specificity 74.7 per cent, positive predictive value 80.3 per cent and negative predictive value 88.7 per cent. Higher values of IP-10 were associated with increasing stages of fibrosis (P<0.01) and higher grades of inflammation (P=0.02, P=0.07) assessed morphologically and noninvasively through FibroTest and ActiTest. Significant steatosis and IR were also associated with increased levels of IP-10 (P=0.01 and P=0.02). In multivariate analysis, IP-10 levels and fibrosis stages were independently associated with SVR. INTERPRETATION & CONCLUSIONS Our findings showed that the assessment of serum IP-10 level could be a predictive factor for SVR and it was associated with fibrosis, necroinflammatory activity, significant steatosis and IR in patients with chronic HCV infection.

Abstract
OBJECTIVE Liver biopsy is the most accurate method for determining stage and grade of injury in non-alcoholic fatty liver disease (NAFLD). Given risks and limitations of biopsy, non-invasive tests such as NAFLD fibrosis score, aspartate transaminase (AST) to platelet ratio index, Fib-4, AST/alanine transaminase ratio and BARD are used. Prevalence and severity of NAFLD and metabolic syndrome vary by ethnicity, yet tests have been developed in largely white populations. We tested our hypothesis that non-invasive tests that include metabolic parameters are less accurate in South Asian compared with white patients. DESIGN Retrospective cross-sectional. SETTING Specialist liver centre. PATIENTS Patients with histologically confirmed NAFLD. INTERVENTIONS Scores calculated using clinical data taken within 1 week and compared with histology (Kleiner). MAIN OUTCOME MEASURES Diagnostic test characteristics. RESULTS 175 patients were identified. South Asians (n=90) were younger, had lower body mass index and lower proportion of obesity compared with white patients (n=79), with comparable rates of diabetes and liver injury. Tests are less sensitive at detecting advanced fibrosis in South Asian compared with white patients. Relative risk of correct diagnosis in white patients compared with South Asians is 1.86 (95% CI 1.4 to 2.6). In binary logistic regression models, ethnicity and platelet count predicted accuracy. Transient elastography was equally and highly accurate in both ethnicities. CONCLUSIONS Blood test-based non-invasive scores are less accurate in South Asian patients, irrespective of metabolic parameters. Ethnicity should be considered when devising risk-stratification algorithms for NAFLD.

Abstract
Given recent profound improvements in the effectiveness of antiviral treatment for chronic Hepatitis C virus (HCV) infection, we aimed to describe the characteristics of patients referred to hepatology expert centres in France from 2000 to 2007 and from 2010 to 2014, and to identify factors associated with severe liver disease at their first visit for evaluation. We analysed data from two sources covering all of France: the former hepatitis C surveillance network, which included patients between 2000 and 2007, and the ANRS CO22 HEPATHER multi-centre cohort, which included patients between 2012 and 2014. Severe liver disease (SLD) was defined as the presence of either cirrhosis (histological, biochemical or clinical) or hepatocellular carcinoma. Multivariable Poisson regression models were used to identify the factors associated with SLD in complete-case analysis and after multiple imputation. Overall, 16,851 patients were included in the analysis and SLD was diagnosed in 11.6%. SLD at first visit was significantly associated with known risk factors (male sex, history of excessive alcohol intake, HCV genotype 3), late referral to hepatologists after diagnosis and HCV diagnosis at an older age. Providing earlier specialised care and treatment may be an important target for public health action.

Abstract
Background/Aims The invasiveness of a liver biopsy and its inconsistent results have prompted efforts to develop noninvasive tools to evaluate the severity of chronic hepatitis. This study was intended to assess the performance of serum biomarkers for predicting liver fibrosis in patients with chronic viral hepatitis. Methods A total of 302 patients with chronic hepatitis B or C, who had undergone liver biopsy, were retrospectively enrolled. We investigated the diagnostic accuracy of several clinical factors for predicting advanced fibrosis (F≥3). Results The study population included 227 patients with chronic hepatitis B, 73 patients with chronic hepatitis C, and 2 patients with co-infection (hepatitis B and C). Histological cirrhosis was identified in 16.2% of the study population. The grade of porto-periportal activity was more correlated with the stage of chronic hepatitis compared with that of lobular activity (r=0.640 vs. r=0.171). Fibrosis stage was correlated with platelet count (r=-0.520), aspartate aminotransferase to platelet ratio index (APRI) (r=0.390), prothrombin time (r=0.376), and albumin (r=-0.357). For the diagnosis of advanced fibrosis, platelet count and APRI were the most predictive variables (AUROC=0.752, and 0.713, respectively). Conclusions In a hepatitis B endemic region, platelet count and APRI could be considered as reliable non-invasive markers for predicting fibrosis of chronic viral hepatitis. However, it is necessary to validate the diagnostic accuracy of these markers in another population.

Liver fibrosis occurs in response to different etiologies of chronic liver injury. Diagnosing degree of liver fibrosis is a crucial step in evaluation of severity of the disease. An invasive liver biopsy is the gold standard method associated with pain and complications. Biomarkers to detect liver fibrosis include direct markers of extracellular matrix turnover and indirect markers as a reflection of liver dysfunction. Although a single marker may not be useful for successful management, a mathematical equation combining tests might be effective. The main purpose of this review is to understand the diagnostic accuracy of biomarkers and scoring systems for liver fibrosis. Advances in -omics approach have generated clinically significant biomarker candidates for liver fibrosis that need further evaluation.

Abstract
Patients with HIV have a proclivity to develop liver fibrosis, especially when associated with other conditions such as HCV, HBV, and NAFLD. Identifying HIV-infected patients with significant fibrosis or cirrhosis plays an important role in clinical and therapeutic decision-making. Liver biopsy is currently considered as the gold standard for fibrosis assessment but carries many shortcomings (cost, invasiveness, complications, false negative rate of 20 %). Multiple non-invasive methods of liver fibrosis assessment have been developed, but not all have been studied in HIV-infected individuals. Non-invasive liver fibrosis tools include both serologic-based testing scores (rely on direct and/or indirect markers) such as APRI, FIB4, FibroTest, FibroSpect II, HepaScore, or imaging-based methods such as vibration controlled liver elastography. There is validated data to support the use of non-invasive modalities of fibrosis assessment in HIV-HCV co-infected individuals for the exclusion of cirrhosis, but may be poorly reliable or not enough data exists for the assessment of other co-morbid disease processes.

Abstract
Neuroendocrine cells are widely distributed throughout the body. They can produce, store, and secrete peptides and biogenic amines. Neuroendocrine tumors (NETs) are rare, but most are found in the intestine, pancreas, and lung. NETs may cause specific hormonal symptoms (eg, carcinoid syndrome) or appear nonfunctional. Blood or urine concentrations of tumor-secreted amines and peptides have been used as biomarkers in the diagnosis and management of NETs. This article focuses on currently available biochemical testing of blood or urine for gastroenteropancreatic and lung NETs and discusses the limitations of these tests and the potential role of newer multianalyte markers for NET management.

Aliment Pharmacol Ther 2017; 45:991-1003. [PMID: 28164327 DOI: 10.1111/apt.13954] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/19/2016] [Revised: 12/09/2016] [Accepted: 01/05/2017] [Indexed: 02/06/2023]
Abstract
BACKGROUND In chronic hepatitis C, the European Association for the Study of the Liver and the Asociacion Latinoamericana para el Estudio del Higado recommend performing transient elastography plus a blood test to diagnose significant fibrosis; test concordance confirms the diagnosis. AIM To validate this rule and improve it by combining a blood test, FibroMeter (virus second generation, Echosens, Paris, France) and transient elastography (constitutive tests) into a single combined test, as suggested by the American Association for the Study of Liver Diseases and the Infectious Diseases Society of America. METHODS A total of 1199 patients were included in an exploratory set (HCV, n = 679) or in two validation sets (HCV ± HIV, HBV, n = 520). Accuracy was mainly evaluated by correct diagnosis rate for severe fibrosis (pathological Metavir F ≥ 3, primary outcome) by classical test scores or a fibrosis classification, reflecting Metavir staging, as a function of test concordance. RESULTS Score accuracy: there were no significant differences between the blood test (75.7%), elastography (79.1%) and the combined test (79.4%) (P = 0.066); the score accuracy of each test was significantly (P < 0.001) decreased in discordant vs. concordant tests. Classification accuracy: combined test accuracy (91.7%) was significantly (P < 0.001) increased vs. the blood test (84.1%) and elastography (88.2%); accuracy of each constitutive test was significantly (P < 0.001) decreased in discordant vs. concordant tests but not with combined test: 89.0 vs. 92.7% (P = 0.118). Multivariate analysis for accuracy showed an interaction between concordance and fibrosis level: in the 1% of patients with full classification discordance and severe fibrosis, non-invasive tests were unreliable. The advantage of combined test classification was confirmed in the validation sets. CONCLUSIONS The concordance recommendation is validated. A combined test, expressed in classification instead of score, improves this rule and validates the recommendation of a combined test, avoiding 99% of biopsies, and offering precise staging.

Fibrosis assessment using FibroMeter combined to first generation tests in hepatitis C. World J Hepatol 2017; 9:310-317. [PMID: 28293380 PMCID: PMC5332420 DOI: 10.4254/wjh.v9.i6.310] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/25/2016] [Revised: 12/15/2016] [Accepted: 02/13/2017] [Indexed: 02/06/2023] Open
Abstract
AIM To evaluate the performance of FibroMeterVirus3G combined to the first generation tests aspartate aminotransferase-to-platelet ratio index (APRI) or Forns index to assess significant fibrosis in chronic hepatitis C (CHC).
METHODS First generation tests APRI or Forns were initially applied in a derivation population from Rio de Janeiro in Brazil considering cut-offs previously reported in the literature to evaluate significant fibrosis. FibroMeterVirus3G was sequentially applied to unclassified cases from APRI or Forns. Accuracy of non-invasive combination of tests, APRI plus FibroMeterVirus3G and Forns plus FibroMeterVirus3G was evaluated in the Brazilian derivation population. APRI plus FibroMeterVirus3G combination was validated in a population of CHC patients from Angers in France. All patients were submitted to liver biopsy staged according to METAVIR score by experienced hepatopathologists. Significant fibrosis was considered as METAVIR F ≥ 2. The fibrosis stage classification was used as the reference for accuracy evaluation of non-invasive combination of tests. Blood samples for the calculation of serum tests were collected on the same day of biopsy procedure or within a maximum 3 mo interval and stored at -70 °C.
RESULTS Seven hundred and sixty CHC patients were included (222 in the derivation population and 538 in the validation group). In the derivation population, the FibroMeterVirus3G AUROC was similar to APRI AUROC (0.855 vs 0.815, P = 0.06) but higher than Forns AUROC (0.769, P < 0.001). The best FibroMeterVirus3G cut-off to discriminate significant fibrosis was 0.61 (80% diagnostic accuracy; 75% in the validation population, P = 0.134). The sequential combination of APRI or Forns with FibroMeterVirus3G in derivation population presented similar performance compared to FibroMeterVirus3G used alone (79% vs 78% vs 80%, respectively, P = 0.791). Unclassified cases of significant fibrosis after applying APRI and Forns corresponded to 49% and 54%, respectively, of the total sample. However, the combination of APRI or Forns with FibroMeterVirus3G allowed 73% and 77%, respectively, of these unclassified cases to be correctly evaluated. Moreover, this combination resulted in a reduction of FibroMeterVirus3G requirement in approximately 50% of the entire sample. The stepwise combination of APRI and FibroMeterVirus3G applied to the validation population correctly identified 74% of patients with severe fibrosis (F ≥ 3).
CONCLUSION The stepwise combination of APRI or Forns with FibroMeterVirus3G may represent an accurate lower cost alternative when evaluating significant fibrosis, with no need for liver biopsy.

Abstract
BACKGROUND & AIMS The progression of chronic HCV infection varies significantly depending on patient characteristics. The goal of the present study was to evaluate the consequences of targeted and universal therapy for HCV-related morbidity-mortality based on the use of non-invasive diagnostic tests in France, Italy and the UK. METHODS A country-specific Markov model was used to predict clinical outcomes in patients with chronic HCV mono-infection over 5years. Therapeutic strategies used in the three countries analysed: no treatment, targeted therapy based on stage of fibrosis (F2- or F3-scenario), treatment regardless of stage of fibrosis (universal analysis), base-case analysis and yearly assessments. RESULTS Universal therapy is the most effective strategy and reduced the 5-year incidence of cirrhosis by 12.0-17.7, liver complications by 4.2-5.3 and liver deaths by 3.7-4.7, vs. no treatment. In base-case analysis, the F2-scenario using FibroScan or patented blood biomarkers reduces the 5-year incidence of cirrhosis by 2.7-4.0, liver complications by 3.5-3.7 and liver deaths by 3.3-3.7, vs. no treatment. The results of the F3-scenario are poor for the incidence of cirrhosis, and moderately effective for the liver complications. The alternative analysis with a yearly assessment of fibrosis improves the impact of targeted therapy. CONCLUSION By quantifying the impact of different strategies of targeted therapy and universal therapy, this study could help health agencies and experts to draft therapeutic guidelines for HCV-related fibrosis. LAY SUMMARY The impact of different treatment strategies was evaluated in three countries, France, Italy and UK, using a mathematical model. This analysis showed that: i) A prioritization strategy of HCV treatment for patients with advanced disease would decrease the overall impact of treatment on morbidity and mortality; and ii) A strategy initiating HCV treatment to all would already show a benefit in reducing 5-year morbidity and mortality.

Abstract
BACKGROUND Blood tests of liver injury are less well validated in non-alcoholic fatty liver disease (NAFLD) than in patients with chronic viral hepatitis. AIMS To improve the validation of three blood tests used in NAFLD patients, FibroTest for fibrosis staging, SteatoTest for steatosis grading and ActiTest for inflammation activity grading. METHODS We pre-included new NAFLD patients with biopsy and blood tests from a single-centre cohort (FibroFrance) and from the multicentre FLIP consortium. Contemporaneous biopsies were blindly assessed using the new steatosis, activity and fibrosis (SAF) score, which provides a reliable and reproducible diagnosis and grading/staging of the three elementary features of NAFLD (steatosis, inflammatory activity) and fibrosis with reduced interobserver variability. We used nonbinary-ROC (NonBinAUROC) as the main endpoint to prevent spectrum effect and multiple testing. RESULTS A total of 600 patients with reliable tests and biopsies were included. The mean NonBinAUROCs (95% CI) of tests were all significant (P < 0.0001): 0.878 (0.864-0.892) for FibroTest and fibrosis stages, 0.846 (0.830-0.862) for ActiTest and activity grades, and 0.822 (0.804-0.840) for SteatoTest and steatosis grades. FibroTest had a higher NonBinAUROC than BARD (0.836; 0.820-0.852; P = 0.0001), FIB4 (0.845; 0.829-0.861; P = 0.007) but not significantly different than the NAFLD score (0.866; 0.850-0.882; P = 0.26). FibroTest had a significant difference in median values between adjacent stage F2 and stage F1 contrarily to BARD, FIB4 and NAFLD scores (Bonferroni test P < 0.05). CONCLUSIONS In patients with NAFLD, SteatoTest, ActiTest and FibroTest are non-invasive tests that offer an alternative to biopsy, and they correlate with the simple grading/staging of the SAF scoring system across the three elementary features of NAFLD: steatosis, inflammatory activity and fibrosis.

Abstract
Chronic liver disease has multiple causes, many of which are increasing in prevalence. The final common pathway of chronic liver disease is tissue destruction and attempted regeneration, a pathway that triggers fibrosis and eventual cirrhosis. Assessment of fibrosis is important not only for diagnosis but also for management, prognostic evaluation, and follow-up of patients with chronic liver disease. Although liver biopsy has traditionally been considered the reference standard for assessment of liver fibrosis, noninvasive techniques are the emerging focus in this field. Ultrasound-based elastography and magnetic resonance (MR) elastography are gaining popularity as the modalities of choice for quantifying hepatic fibrosis. These techniques have been proven superior to conventional cross-sectional imaging for evaluation of fibrosis, especially in the precirrhotic stages. Moreover, elastography has added utility in the follow-up of previously diagnosed fibrosis, the assessment of treatment response, evaluation for the presence of portal hypertension (spleen elastography), and evaluation of patients with unexplained portal hypertension. In this article, a brief overview is provided of chronic liver disease and the tools used for its diagnosis. Ultrasound-based elastography and MR elastography are explored in depth, including a brief glimpse into the evolution of elastography. Elastography is based on the principle of measuring tissue response to a known mechanical stimulus. Specific elastographic techniques used to exploit this principle include MR elastography and ultrasonography-based static or quasistatic strain imaging, one-dimensional transient elastography, point shear-wave elastography, and supersonic shear-wave elastography. The advantages, limitations, and pitfalls of each modality are emphasized. ©RSNA, 2016.

Tenofovir alafenamide versus tenofovir disoproxil fumarate for the treatment of patients with HBeAg-negative chronic hepatitis B virus infection: a randomised, double-blind, phase 3, non-inferiority trial. Lancet Gastroenterol Hepatol 2016; 1:196-206. [PMID: 28404092 DOI: 10.1016/s2468-1253(16)30107-8] [Citation(s) in RCA: 306] [Impact Index Per Article: 38.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/17/2016] [Revised: 07/25/2016] [Accepted: 07/25/2016] [Indexed: 12/15/2022]
Abstract
BACKGROUND The novel prodrug tenofovir alafenamide delivers the nucleotide reverse transcriptase inhibitor tenofovir to target cells more efficiently at a lower dose than tenofovir disoproxil fumarate, thereby reducing systemic exposure. We compared the efficacy and safety of the two drugs in patients with HBeAg-negative chronic hepatitis B virus (HBV) infection in a non-inferiority study. METHODS In this ongoing randomised, double-blind, phase 3, non-inferiority study in 105 centres in 17 countries, patients with HBeAg-negative chronic HBV were randomly assigned (2:1) by a computer-generated allocation sequence (block size six), stratified by plasma HBV DNA concentration and previous treatment status, to receive once-daily oral doses of tenofovir alafenamide 25 mg or tenofovir disoproxil fumarate 300 mg, each with matching placebo. Participants, investigators, and those assessing outcomes were masked to group assignment. Eligible patients were aged at least 18 years with HBeAg-negative chronic HBV infection (with plasma HBV DNA concentrations of >20 000 IU/mL), serum alanine aminotransferase concentrations of greater than 60 U/L in men or greater than 38 U/L in women and at no more than ten times the upper limit of normal, and estimated creatinine clearance of at least 50 mL/min (by the Cockcroft-Gault method). The primary efficacy endpoint was the proportion of patients who had HBV DNA less than 29 IU/mL at week 48 in those who received at least one dose of study drug; the study was powered to show non-inferiority with a 10% efficacy margin of tenofovir alafenamide compared with tenofovir disoproxil fumarate. Bone and renal safety, and key secondary safety endpoints were assessed sequentially. The study will be conducted for a total of 3 years as a double-blind comparison to assess the longer term response to treatment. This study is registered with ClinicalTrials.gov, number NCT01940341. FINDINGS Between Sept 12, 2013, and Oct 31, 2014, 426 patients were randomly assigned (285 assigned to tenofovir alafenamide and 141 assigned to tenofovir disoproxil fumarate; one patient assigned to tenofovir disoproxil fumarate did not receive the treatment. 268 (94%) of 285 patients receiving tenofovir alafenamide had HBV DNA less than 29 IU/mL at week 48 versus 130 (93%) of 140 patients receiving tenofovir disoproxil fumarate (difference 1·8% [95% CI -3·6 to 7·2]; p=0·47), which demonstrates non-inferiority. Patients receiving tenofovir alafenamide had significantly smaller mean percentage declines in bone mineral density than those receiving tenofovir disoproxil fumarate (hip -0·29% [95% CI -0·55 to -0·03] vs -2·16% [-2·53 to -1·79], adjusted percentage difference 1·87% [95% CI 1·42 to 2·32; p<0·0001]; spine -0·88% [-1·22 to -0·54] vs -2·51% [-3·09 to -1·94], adjusted percentage difference 1·64% [95% CI 1·01 to 2·27]; p<0·0001). At week 48, mean change in serum creatinine was small in both groups (tenofovir alafenamide 0·01 mg/dL [95% CI 0·00 to 0·02] vs tenofovir disoproxil fumarate 0·02 mg/dL [0·00 to 0·04], adjusted percentage difference -0·01 mg/dL [95% CI -0·03 to 0·01]; p=0·32), but patients receiving tenofovir alafenamide had a smaller reduction in creatinine clearance (median change in estimated glomerular filtration rate -1·8 mL/min [IQR -7·8 to 6·0] vs -4·8 mL/min [-12·0 to 3·0]; p=0·004). Most adverse events were mild to moderate in severity in the two treatment groups. The most common adverse events overall were headache (tenofovir alafenamide 40 [14%] patients vs tenofovir disoproxil fumarate 14 [10%] patients), nasopharyngitis (30 [11%] vs 15 [11%]), and upper respiratory tract infection (35 [12%] vs ten [7%]). 14 (5%) patients receiving tenofovir alafenamide and nine (6%) patients receiving tenofovir disoproxil fumarate had serious adverse events, none of which was deemed by investigators to be related to study treatment; one patient in the tenofovir disoproxil fumarate group died, but this was not deemed to be related to study treatment. INTERPRETATION In patients with HBeAg-negative chronic HBV, the efficacy of tenofovir alafenamide was non-inferior to that of tenofovir disoproxil fumarate, and had improved bone and renal effects. Longer term follow-up is needed to better understand the clinical impact of these changes. FUNDING Gilead Sciences.

Diagnostic accuracy and prognostic significance of blood fibrosis tests and liver stiffness measurement by FibroScan in non-alcoholic fatty liver disease. J Hepatol 2016; 65:570-8.

Abstract
BACKGROUND & AIMS NAFLD is highly prevalent but only a small subset of patients develop advanced liver fibrosis with impaired liver-related prognosis. We aimed to compare blood fibrosis tests and liver stiffness measurement (LSM) by FibroScan for the diagnosis of liver fibrosis and the evaluation of prognosis in NAFLD. METHODS Diagnostic accuracy was evaluated in a cross-sectional study including 452 NAFLD patients with liver biopsy (NASH-CRN fibrosis stage), LSM, and eight blood fibrosis tests (BARD, NAFLD fibrosis score, FibroMeter(NAFLD), aspartate aminotransferase to platelet ratio index (APRI), FIB4, FibroTest, Hepascore, FibroMeter(V2G)). Prognostic accuracy was evaluated in a longitudinal study including 360 NAFLD patients. RESULTS LSM and FibroMeter(V2G) were the two best-performing tests in the cross-sectional study: AUROCs for advanced fibrosis (F3/4) were, respectively, 0.831±0.019 and 0.817±0.020 (p⩽0.041 vs. other tests); rates of patients with ⩾90% negative/positive predictive values for F3/4 were 56.4% and 46.7% (p<0.001 vs. other tests); Obuchowski indexes were 0.834±0.014 and 0.798±0.016 (p⩽0.036 vs. other tests). Two fibrosis classifications were developed to precisely estimate the histological fibrosis stage from LSM or FibroMeter(V2G) results without liver biopsy (diagnostic accuracy, respectively: 80.8% vs. 77.4%, p=0.190). Kaplan-Meier curves in the longitudinal study showed that both classifications categorised NAFLD patients into subgroups with significantly different prognoses (p<0.001): the higher was the class of the fibrosis classification, the worse was the prognosis. CONCLUSIONS LSM and FibroMeter(V2G) were the most accurate of nine evaluated tests for the non-invasive diagnosis of liver fibrosis in NAFLD. LSM and FibroMeter(V2G) fibrosis classifications help physicians estimate both fibrosis stage and patient prognosis in clinical practice. LAY SUMMARY The amount of liver fibrosis is the main determinant of the liver-related prognosis in patients with non-alcoholic fatty liver disease (NAFLD). We evaluated eight blood tests and FibroScan in a cross-sectional diagnostic study and found that FibroScan and the blood test FibroMeter(V2G) were the two most accurate tests for the non-invasive evaluation of liver fibrosis in NAFLD. A longitudinal prognostic study showed these two tests initially developed for the diagnosis are also prognostic markers as they allow for the stratification of NAFLD patients in several subgroups with significantly different prognosis.

Abstract
Background High-throughput technologies have the potential to identify non-invasive biomarkers of liver pathology and improve our understanding of basic mechanisms of liver injury and repair. A metabolite profiling approach was employed to determine associations between alterations in serum metabolites and liver histology in patients with chronic hepatitis C virus (HCV) infection. Methods Sera from 45 non-diabetic patients with chronic HCV were quantitatively analyzed using 1H-NMR spectroscopy. A metabolite profile of advanced fibrosis (METAVIR F3-4) was established using orthogonal partial least squares discriminant analysis modeling and validated using seven-fold cross-validation and permutation testing. Bioprofiles of moderate to severe steatosis (≥33 %) and necroinflammation (METAVIR A2-3) were also derived. The classification accuracy of these profiles was determined using areas under the receiver operator curves (AUROCSs) measuring against liver biopsy as the gold standard. Results In total 63 spectral features were profiled, of which a highly significant subset of 21 metabolites were associated with advanced fibrosis (variable importance score >1 in multivariate modeling; R2 = 0.673 and Q2 = 0.285). For the identification of F3–4 fibrosis, the metabolite bioprofile had an AUROC of 0.86 (95 % CI 0.74–0.97). The AUROCs for the bioprofiles for moderate to severe steatosis were 0.87 (95 % CI 0.76–0.97) and for grade A2–3 inflammation were 0.73 (0.57–0.89). Conclusion This proof-of-principle study demonstrates the utility of a metabolomics profiling approach to non-invasively identify biomarkers of liver fibrosis, steatosis and inflammation in patients with chronic HCV. Future cohorts are necessary to validate these findings.
