Metabolic Dysfunction-Associated Steatotic Liver Disease: Navigating Terminological Evolution, Diagnostic Frontiers and Therapeutic Horizon-an Editorial Exploration

Metabolic dysfunction-associated steatotic liver disease (MASLD), once known as non-alcoholic fatty liver disease (NAFLD), represents a spectrum of liver disorders characterized by lipid accumulation within hepatocytes. The redefinition of NAFLD in 2023 marked a significant reposition in terminology, emphasizing a broader understanding of liver steatosis and its associated risks. MASLD is now recognized as a major risk factor for liver cirrhosis, hepatocellular carcinoma, and systemic complications such as cardiovascular diseases or systemic inflammation. Diagnostic challenges arise, particularly in identifying MASLD in lean individuals, necessitating updated diagnostic protocols and investing in non-invasive diagnostic tools. Therapeutically, there is an urgent need for effective treatments targeting MASLD, with emerging pharmacological options focusing on, among others, carbohydrate and lipid metabolism. Additionally, understanding the roles of bile acid metabolism, the microbiome, and dietary interventions in MASLD pathogenesis and management holds promise for innovative therapeutic approaches. There is a strong need to emphasize the importance of collaborative efforts in understanding, diagnosing, and managing MASLD to improve physicians’ approaches and patient outcomes.
