BACKGROUND AND AIMS: Ultrasonography (US) is recommended for HCC surveillance in high-risk patients, but has limited performance in detecting early-stage HCC. We aimed to compare the diagnostic performance of biannual US and annual non-contrast abbreviated magnetic resonance imaging (NC-AMRI) as HCC surveillance modalities in high-risk patients. METHODS: This prospective, multicenter cohort study enrolled participants with an estimated annual risk of HCC greater than 5% between October 2015 and April 2017...

BACKGROUND AND AIMS: In individuals highly exposed to hepatitis C virus (HCV), reinfection is common, suggesting that natural development of sterilising immunity is difficult. In those that are reinfected, some will develop a persistent infection, while a small proportion repeatedly clear the virus, suggesting natural protection is possible. The aim of this study was to characterise immune responses associated with rapid natural clearance of HCV reinfection. METHODS: Broad neutralising antibodies (BnAbs) and Envelope 2 (E2)-specific memory B cell (MBCs) responses were examined longitudinally in 15 subjects with varied reinfection outcomes...

BACKGROUND & AIMS: Endoplasmic reticulum (ER) membrane protein complex subunit 10 (EMC10) has been implicated in obesity. Here we investigated the roles of the two isoforms of EMC10, including a secreted isoform (scEMC10) and an ER membrane-bound isoform (mEMC10), in MASLD. METHODS: Manifold steatotic mouse models and HepG2 cells were employed to investigate the role of EMC10 in the regulation of hepatic PERK-eIF2α-ATF4 signaling and hepatosteatosis. The therapeutic effect of scEMC10-neutralizing antibody on mouse hepatosteatosis was explored...

BACKGROUND & AIMS: Polyploidy in hepatocytes has been proposed as a genetic mechanism to buffer against transcriptional dysregulation. Here, we aim to demonstrate the role of polyploidy in modulating gene regulatory networks in hepatocytes during ageing. METHODS: We performed single-nucleus RNA-sequencing in hepatocyte nuclei of different ploidy levels isolated from young and old wild-type mice. Changes in the gene expression and regulatory network were compared to three independent haploinsufficient strains for HNF4A, CEBPA or CTCF, representing non-deleterious perturbations...

BACKGROUND & AIMS: Functional cure (FC) for chronic hepatitis B (CHB) requires finite treatment. Two agents under investigation aimed at achieving FC are small interfering RNA JNJ-73763989 (JNJ-3989) and capsid assembly modulator JNJ-56136379 (JNJ-6379; bersacapavir). METHODS: REEF-2, a phase 2b, double-blind, placebo-controlled, randomized study (ClinicalTrials.gov Identifier: NCT04129554), enrolled 130 nucleos(t)ide analog (NA)-suppressed hepatitis B e-antigen (HBeAg)-negative CHB patients who received JNJ-3989 (200 mg subcutaneously every 4 weeks)+JNJ-6379 (250 mg oral daily)+NA (oral daily; active arm) or placebos for JNJ-3989 and JNJ-6379 + active NA (control arm) for 48 weeks followed by 48 weeks off-treatment follow-up...

BACKGROUND & AIMS: Steatotic liver disease (SLD), characterized by elevated liver fat content (LFC), is influenced by genetics and diet. However, whether diet has differential effect based on genetic risk is not well-characterized. We aimed to determine how genetic factors interact with diet to affect SLD in a large national biobank. METHODS: We included UK Biobank participants with dietary intake measured by 24-hour recall and genotyping. The primary predictors were dietary pattern, PNPLA3-rs738409-G, TM6SF2-rs58542926-T, a 16-variant hepatic steatosis polygenic risk score (PRS), and gene-environment interactions...

Acute-on-chronic liver failure (ACLF), usually precipitated by alcohol misuse or viral reactivation, is a rapid onset and usually reversible liver failure. There have been various definitions of ACLF proposed across the globe, including, Asian Pacific Association for the Study of Liver (APASL), Chinese Group on the Study of Severe Hepatitis B (COSSH), European Association for the Study of Liver-Consortium for Liver Failure (EASL-CLIF), Japanese definition, and North American Consortium for the Study of End-Stage Liver Disease (NACSELD) have been widely used...

BACKGROUND & AIMS: Cystic fibrosis-related liver disease (CFLD) is a chronic cholangiopathy that increases morbidity and mortality in patients with CF. Current treatments are unsatisfactory, and incomplete understanding of CFLD pathogenesis hampers therapeutic development. We have previously shown that mouse CF cholangiocytes respond with excessive inflammation to LPS. Thus, we investigated the role of the gut-liver axis in the pathogenesis of CFLD. METHODS: Wild-type (WT), whole-body CFTR knockout (CFTR-KO) and gut-corrected (CFTR-KO-GC) mice were studied...

The rising prevalence of liver diseases related to obesity and excessive use of alcohol is fuelling an increasing demand for accurate biomarkers aimed at community screening, diagnosis of steatohepatitis and significant fibrosis, monitoring, prognosis and prediction of treatment efficacy. Breakthroughs in omics methodologies and the power of bioinformatics have created an excellent opportunity to combine clinical needs with technological advancements. Omics technologies allow for advanced investigations into biological processes from the genes to transcription and regulation, to circulating protein, metabolite and lipid levels, as well as the microbiome including bacteria, viruses and fungi...

BACKGROUND AND AIMS: There has been a lack of prospective data on treatment after immune checkpoint inhibitor (ICI) in hepatocellular carcinoma (HCC). We conducted a phase II multicentred study on cabozantinib in HCC after ICI treatment. METHODS: This is an investigator-initiated single-arm clinical trial involving academic centres in Hong Kong and Korea. Key eligibility criteria include diagnosis of HCC; refractoriness to prior ICI-based treatment; Child-Pugh A liver function...

BACKGROUND: Non-invasive scores have been proposed to identify patients with fibrotic, metabolic dysfunction associated steatohepatitis (MASH), who are at the highest risk of progression to complications of cirrhosis and may benefit from pharmacologic treatments. However, data in type 2 diabetes (T2DM) patients are lacking. The aim of this multicenter prospective study was to compare head-to-head FAST (FibroScan-aspartate aminotransferase [AST]), MAST (magnetic resonance imaging [MRI]-AST), MEFIB (magnetic resonance elastography [MRE] plus FIB-4), and FNI (fibrotic NASH index) for detecting fibrotic MASH in T2DM patients...
