Abstract
One-third of adults across the globe exhibit metabolic dysfunction-associated steatotic liver disease (MASLD) - formerly known as nonalcoholic fatty liver disease (NAFLD). To date, MASLD is the fastest-growing etiology of chronic liver disease and hepatocellular carcinoma (HCC). Besides the population with obesity, MASLD can also be found in lean populations, accounting for 13% of the global population, especially Asians. Notably, individuals with lean MASLD face equal or higher overall mortality rates compared to their non-lean counterparts. Risk modifiers encompass advanced age, hepatic fibrosis, and type 2 diabetes mellitus (T2DM). Moreover, the population with lean MASLD is associated with an increased risk of HCC, while their non-lean counterparts are more prone to cardiovascular outcomes and T2DM. Existing evidence indicates a similar risk of liver-related events and extrahepatic cancer between the two groups. However, MASLD-related genetic variants, such as PNPLA3 and TM6SF2, did not significantly affect mortality between the two populations. Still, underreporting alcohol consumption and regional representation limits the study's comprehensiveness. Longitudinal studies and mechanistic explorations are needed to understand differences in lean versus non-lean MASLD populations. This review highlights the need for awareness and tailored interventions in managing MASLD, considering lean individuals' unique risks.
期刊介绍:
Clinical and Molecular Hepatology is an internationally recognized, peer-reviewed, open-access journal published quarterly in English. Its mission is to disseminate cutting-edge knowledge, trends, and insights into hepatobiliary diseases, fostering an inclusive academic platform for robust debate and discussion among clinical practitioners, translational researchers, and basic scientists. With a multidisciplinary approach, the journal strives to enhance public health, particularly in the resource-limited Asia-Pacific region, which faces significant challenges such as high prevalence of B viral infection and hepatocellular carcinoma. Furthermore, Clinical and Molecular Hepatology prioritizes epidemiological studies of hepatobiliary diseases across diverse regions including East Asia, North Asia, Southeast Asia, Central Asia, South Asia, Southwest Asia, Pacific, Africa, Central Europe, Eastern Europe, Central America, and South America.
The journal publishes a wide range of content, including original research papers, meta-analyses, letters to the editor, case reports, reviews, guidelines, editorials, and liver images and pathology, encompassing all facets of hepatology.
