EASL-EASD-EASO Clinical Practice Guidelines on the management of metabolic dysfunction-associated steatotic liver disease (MASLD): Executive Summary
Abstract
Metabolic dysfunction-associated steatotic liver disease (MASLD), previously termed non-alcoholic fatty liver disease (NAFLD), is defined as steatotic liver disease (SLD) in the presence of one or more cardiometabolic risk factor(s) and the absence of harmful alcohol intake. The spectrum of MASLD includes steatosis, metabolic dysfunction-associated steatohepatitis (MASH, previously NASH), fibrosis, cirrhosis and MASH-related hepatocellular carcinoma (HCC). This joint EASL-EASD-EASO guideline provides an update on definitions, prevention, screening, diagnosis and treatment for MASLD. Case-finding strategies for MASLD with liver fibrosis, using non-invasive tests, should be applied in individuals with cardiometabolic risk factors, abnormal liver enzymes and/or radiological signs of hepatic steatosis, particularly in the presence of type 2 diabetes or obesity with additional metabolic risk factor(s). A stepwise approach using blood-based scores (such as the fibrosis-4 index [FIB-4]) and, sequentially, imaging techniques (such as transient elastography) is suitable to rule-out/in advanced fibrosis, which is predictive of liver-related outcomes. In adults with MASLD, lifestyle modification-including weight loss, dietary changes, physical exercise and discouraging alcohol consumption-as well as optimal management of comorbidities-including use of incretin-based therapies (e.g. semaglutide, tirzepatide) for type 2 diabetes or obesity, if indicated-is advised. Bariatric surgery is…
