Differences in the incidence of cirrhosis-associated complications between MASLD, MetALD and ALD among patients with decompensated liver cirrhosis.

Background: Recently, the new definition of steatotic liver disease (SLD) has been introduced, which not only differentiates MASLD (Metabolic Dysfunction-Associated steatotic liver disease) from alcohol-related steatotic liver disease (ALD), but also introduces the concept of metabolic and alcohol-related SLD (MetALD). However, potential differences of the new etiologies regarding the clinical phenotype of patients with advanced liver cirrhosis still remain undetermined. Therefore, we analyzed survival and the incidence of cirrhosis-related complications in SLD-patients with advanced liver cirrhosis.

Elevated Plasma CXCL8 Concentrations in Significant Fibrosis but Not in Subclinical Rejection After Adult Liver Transplantation.

Background: The noninvasive detection of subclinical graft injury including subclinical T cell-mediated rejection (subTCMR) is one of the unresolved challenges after liver transplantation. Recently, serum C-X-C motif chemokine ligand 8 (CXCL8) was proposed as a highly accurate marker of subTCMR in pediatric liver transplant recipients. We aimed to evaluate the accuracy of the quantification of this chemokine for predicting subTCMR in adult liver transplant recipients, as well as its capacity to classify patients who could benefit from immunosuppression reduction.

Novel translational mouse models of metabolic dysfunction-associated steatotic liver disease comparable to human MASLD with severe obesity.

Objective: Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most common cause of chronic liver disease, especially in patients with severe obesity. However, current mouse models for MASLD do not reflect the polygenetic background nor the metabolic changes in this population. Therefore, we investigated two novel mouse models of MASLD with a polygenetic background for the metabolic syndrome.

Overweight Impacts Histological Disease Activity of De Novo Metabolic Dysfunction-Associated Steatotic Liver Disease After Liver Transplantation.

Background And Aims: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a leading indication for liver transplantation (LT), but also occurs after LT. The prevalence of de novo MASLD (dnMASLD) after LT, based on both surveillance (svLbx) and indication biopsies (indLbx), is unknown. Furthermore, the impact of the distinct cardiometabolic risk factors on histological disease activity has not been assessed.

Folic acid supplementation is associated with a decreased mortality and reduced hospital readmission in patients with decompensated alcohol-related liver cirrhosis.

Background And Aims: Thiamine and folic acid malnutrition is highly frequent in patients with decompensated alcohol-related liver cirrhosis (aLC). Current guidelines therefore recommend vitamin supplementation in these patients. However, implementation and its impact on the clinical outcome remains unknown.

Clinical long-term outcome of hepatitis D compared to hepatitis B monoinfection.

Background And Aims: Hepatitis D virus (HDV) infection causes the most severe form of chronic viral hepatitis. However, it is still unclear to what extent the underlying cirrhosis may contribute to disease progression. The aim of this study was to compare the long-term outcome of HDV infection with HBV monoinfection in a single-center cohort of both non-cirrhotic and cirrhotic patients.

The Detrimental Role of Regulatory T Cells in Nonalcoholic Steatohepatitis.

Nonalcoholic steatohepatitis (NASH) is induced by steatosis and metabolic inflammation. While involvement of the innate immune response has been shown, the role of the adaptive immune response in NASH remains controversial. Likewise, the role of regulatory T cells (Treg) in NASH remains unclear although initial clinical trials aim to target these regulatory responses.

Quantification of polyreactive immunoglobulin G facilitates the diagnosis of autoimmune hepatitis.

Background And Aims: Detection of autoantibodies is a mainstay of diagnosing autoimmune hepatitis (AIH). However, conventional autoantibodies for the workup of AIH lack either sensitivity or specificity, leading to substantial diagnostic uncertainty. We aimed to identify more accurate serological markers of AIH with a protein macroarray.

Telemonitoring-Supported Exercise Training in Employees With Metabolic Syndrome Improves Liver Inflammation and Fibrosis.

Introduction: Metabolic syndrome (MetS) is a major health problem worldwide and the main risk factor for metabolic-associated fatty liver disease (MAFLD). Established treatment options are lifestyle interventions facilitating dietary change and increased physical activity. Here, we tested the effect of a telemonitoring-supported intervention on liver parameter of inflammation and fibrosis in individuals with MetS.

Dulaglutide Alone and in Combination with Empagliflozin Attenuate Inflammatory Pathways and Microbiome Dysbiosis in a Non-Diabetic Mouse Model of NASH.

Dysregulation of glucose homeostasis plays a major role in the pathogenesis of non-alcoholic steatohepatitis (NASH) as it activates proinflammatory and profibrotic processes. Beneficial effects of antiglycemic treatments such as GLP-1 agonist or SGLT-2 inhibitor on NASH in patients with diabetes have already been investigated. However, their effect on NASH in a non-diabetic setting remains unclear.

Novel therapeutic targets in autoimmune hepatitis.

Autoimmune hepatitis (AIH) is an orphan disease characterized by an autoimmune attack against hepatocytes. The exact sequence of events that leads to a breach of tolerance is incompletely understood. Current hypotheses suggest that environmental agents such as toxins or infectious agents like viruses cause a tissue damage that initiates autoimmunity in genetically susceptible individuals.
