Metabolic dysfunction-associated steatotic liver disease (MASLD) is a major public health threat globally. Management of patients afflicted with MASLD and research in this domain are limited by the lack of robust well-established non-invasive biomarkers for diagnosis, prognostication, and monitoring. The circulating metabolome reflects both the systemic metabo-inflammatory milieu and changes in the liver in affected individuals.

Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) is highly prevalent with major risk of progression to Metabolic Dysfunction-Associated Steatohepatitis (MASH) and Hepatocellular Carcinoma (HCC). Recently, osteoporosis and bone fracture have emerged as sexually-dimorphic comorbidities of MASLD yet the mechanisms of this bone loss are unknown. Herein, we address these knowledge gaps using DIAMOND mice which develop MASLD, MASH, and HCC via Western diet exposure.

Article Synopsis
  • Alcoholic hepatitis (AH) causes severe liver inflammation and health risks, and its inflammation resolution is linked to specialized pro-resolving mediators (SPMs) derived from fatty acids.
  • The study measured lipid mediator levels in plasma samples from AH patients, heavy drinkers, and healthy controls, using advanced techniques and analyzed how these mediators relate to clinical markers and alcohol abstinence.
  • Findings revealed AH patients had higher levels of pro-inflammatory lipid mediators and specific SPMs, with a concerning ratio indicating disease severity; however, many of these abnormalities improved after patients abstained from alcohol.

Background: Fibroinflammatory cholangiopathies, such as primary sclerosing cholangitis (PSC) and primary biliary cholangitis (PBC), are characterized by inflammation and biliary fibrosis, driving disease-related complications. In biliary fibrosis, cholangiocytes activated by transforming growth factor-β (TGFβ) release signals that recruit immune cells to drive inflammation and activate hepatic myofibroblasts to deposit the extracellular matrix (ECM). TGFβ regulates stearoyl-CoA desaturase (SCD), an enzyme that catalyzes the synthesis of monounsaturated fatty acids, in stimulating fibroinflammatory lipid signaling.

Obesity and associated insulin resistance induce a chronic metaboinflammatory state that lead to injury and dysfunction of multiple organs resulting in a cluster of noncommunicable diseases such as type 2 diabetes mellitus, hypertension, cardiovascular disease, chronic kidney disease, and metabolic dysfunction-associated steatotic liver disease (MASLD). Metabolic dysfunction-associated steatohepatitis (MASH) is a histologically active form of MASLD and characterized by greater injury and inflammation and progresses to cirrhosis with greater certainty than steatosis alone. The progression to cirrhosis is characterized by increasing fibrosis.

Article Synopsis
  • - Sarcopenia, a condition involving muscle loss, is common in men with liver cirrhosis and has negative effects on health, including increasing the risk of hepatic encephalopathy (HE); androgen receptor agonists (ARAs) like LPCN 1148 show potential to address these issues but their effectiveness and safety in this demographic were previously unclear.
  • - In a phase 2 trial, men with cirrhosis and sarcopenia were given either LPCN 1148 or placebo for 24 weeks, with results indicating that those taking LPCN 1148 had a significant increase in muscle mass (measured by CT scans) and experienced fewer episodes of serious HE compared to the placebo group.

Article Synopsis
  • Scientists studied a health problem called MASH, which affects people's livers, and worked on two tests to help doctors tell if someone has it.
  • They looked at data from over 3,000 people to make sure their first test, called acMASH, worked well, and then created a new test called acFibroMASH to find more severe cases.
  • The new acFibroMASH test was better at predicting who might have future liver problems compared to another test, showing it's a useful tool for doctors to keep patients healthy.

There is a clinical need for a simple test implementable at the primary point of care to identify individuals with metabolic dysfunction-associated steatotic liver disease (MASLD) in the population. Blood plasma samples from adult patients with varying phenotypes of MASLD were used to identify a minimal set of lipid analytes reflective of underlying histologically confirmed MASLD. Samples were obtained from the NIDDK Nonalcoholic Steatohepatitis Clinical Research Network (NASH CRN) NAFLD Database prospective cohort study (MASLD group; N = 301).

The intersection of cardiovascular disease, metabolic disorders and chronic kidney disease represents a complex clinical picture challenging healthcare systems worldwide. Metabolic-dysfunction-associated steatotic liver disease (MASLD) often manifests sequentially or concomitantly with these diseases, and may share underlying mechanisms and risk factors. Growing evidence suggests that new therapies could have benefits across these diseases, but trial sponsors and investigators tend to be reluctant to include patients with comorbidities-particularly liver diseases-in clinical trials.
