BACKGROUND AND AIMS: The impact of hepatitis C virus (HCV) eradication via direct-acting antiviral (DAA) therapy on overall mortality, particularly non-liver-related mortality, is understudied. METHODS: We recruited 4180 patients with chronic HCV infection who achieved sustained virological response (SVR) (HCV eradication) through DAA therapy (n = 2501, SVR group) or who did not receive antiviral therapy (n = 1679, non-SVR group); 1236 from each group were chosen using propensity score matching...

INTRODUCTION: The cumulative impact of metabolic syndrome (MetS) components on micro- and macrovascular disease in metabolic dysfunction-associated steatotic liver disease (MASLD) is unclear. We aimed to determine whether the number of the MetS components increases the risk of micro- and macrovascular disease in patients with MASLD. METHODS: We performed a retrospective cohort study of electronic medical records using the TriNetX network, a global federated database...

BACKGROUND AND AIMS: The association between socioeconomic factors and disease severity is not well studied in people living with metabolic dysfunction-associated steatotic liver disease (MASLD). We thus examined if socioeconomic factors influence the presence of, or risk for future, major adverse liver outcomes (MALOs) in people living with MASLD. METHODS: We conducted a register-based cohort study that included all individuals with a MASLD diagnosis between 1987 and 2020 in Sweden...

BACKGROUND AND AIMS: It has been described that recompensation can improve prognosis in patients with cirrhosis. However, recompensation after transjugular intrahepatic portosystemic shunt (TIPS) has not been studied. We evaluated the impact of recompensation after TIPS on the risk of hepatocellular carcinoma (HCC) and death, and we compared it with compensated cirrhosis patients. METHODS: An observational study of consecutive patients with cirrhosis undergoing TIPS between 2008 and 2022 was performed...

BACKGROUND AND AIMS: Wilson disease (WD) is a rare disorder of copper metabolism, leading to liver and neurological disease. Existing literature on WD in pregnancy is scarce, limiting preconception and obstetrical counselling. In this systematic review with meta-analysis, we determine the prevalence of various adverse pregnancy and neonatal outcomes in WD, as well as evaluate the impact of WD treatment on these outcomes. METHODS: Scopus, MEDLINE and EMBASE were searched until 12 May 2023, for studies of pregnant individuals with WD and at least one pregnancy or neonatal outcome of interest...

BACKGROUND AND AIMS: Patients with overt or occult hepatitis B virus (HBV) infection receiving immunosuppressive treatments have a wide risk of HBV reactivation (HBVr). We performed meta-analysis with decision curve analyses (DCA) to estimate the risk of HBVr in HBsAg-negative anti-HBc-positive patients naïve to nucleos(t)ide analogues (NAs) receiving immunosuppressive treatments. APPROACH AND RESULTS: Studies were identified through literature search until October 2022...

BACKGROUND AND AIMS: Hepatitis C virus (HCV) burden is higher among people in prison given high prevalence of injecting drug use. This study evaluated direct-acting antiviral (DAA) treatment outcome in prisons. METHODS: The Surveillance and Treatment of Prisoners with hepatitis C (SToP-C) study enrolled individuals incarcerated in four Australian prisons (2017-2019). Participants with detectable HCV RNA were offered sofosbuvir-velpatasvir for 12 weeks. Sustained virological response (SVR) was assessed in intention-to-treat (ITT; participants commencing treatment and due for SVR assessment before study close) and per-protocol (PP; participants with documented treatment completion and SVR assessment) populations...

BACKGROUND & AIMS: There is an unmet need for a reliable and reproducible non-invasive measure of fatty liver content (FLC) for monitoring steatotic liver disease in clinical practice. Sonographic FLC assessment is qualitative and operator-dependent, and the dynamic quantification range of algorithms based on a single ultrasound (US) parameter is unsatisfactory. This study aims to develop and validate a new multiparametric algorithm based on B-mode images to quantify FLC using Magnetic Resonance (MR) values as standard reference...

BACKGROUND AND AIMS: Severe acute respiratory syndrome coronavirus (SARS-CoV-2) preferentially infects the respiratory tract; however, several studies have implicated a multi-organ involvement. Hepatic dysfunctions caused by SARS-CoV-2 infection have been increasingly recognized and described to correlate with disease severity. To elucidate molecular factors that could contribute towards hepatic infection, we concentrated on microRNAs (miRNAs), a class of small non-coding RNAs that modulate various cellular processes and which are reported to be differentially regulated during liver injury...

The diagnosis of idiosyncratic drug-induced liver injury (DILI) is a challenging task due to the lack of specific features or definitive diagnostic tools. A minimum of clinical and pharmacological information is required, together with laboratory and imaging tests to exclude other causes of liver injury. Several standardized methods have been developed to support clinical judgement and establish causality assessment, the most widely used being the Roussel Uclaf Causality Assessment Method-RUCAM-and structured Expert Opinion...

BACKGROUND AND AIMS: Cholangiocarcinoma (CCA) is an aggressive malignancy arising from the intrahepatic (iCCA) or extrahepatic (eCCA) bile ducts with poor prognosis and limited treatment options. Prior evidence highlighted a significant contribution of the non-canonical NF-κB signalling pathway in initiation and aggressiveness of different tumour types. Lymphotoxin-β (LTβ) stimulates the NF-κB-inducing kinase (NIK), resulting in the activation of the transcription factor RelB...

BACKGROUND AND AIMS: During fasting, bodily homeostasis is maintained due to hepatic production of glucose (gluconeogenesis) and ketone bodies (ketogenesis). The main hormones governing hepatic fuel production are glucagon and glucocorticoids that initiate transcriptional programs aimed at supporting gluconeogenesis and ketogenesis. METHODS: Using primary mouse hepatocytes as an ex vivo model, we employed transcriptomic analysis (RNA-seq), genome-wide profiling of enhancer dynamics (ChIP-seq), perturbation experiments (inhibitors, shRNA), hepatic glucose production measurements and computational analyses...

IMPORTANCE: The recent change in terminology from nonalcoholic fatty liver disease (NAFLD) to metabolic dysfunction-associated fatty liver disease (MAFLD) and metabolic dysfunction-associated steatotic liver disease (MASLD) highlights the link between hepatic steatosis and metabolic dysfunction, taking out the stigmata of alcohol. OBJECTIVE: We compared the effects of NAFLD and MAFLD definitions on the risk of overall and cardiovascular (CV) mortality, liver-related events (LRE), nonfatal CV events (CVE), chronic kidney disease (CKD), and extra-hepatic cancers (EHC)...
