Initial outcomes of a dedicated multidisciplinary non-alcoholic fatty liver disease clinic: a retrospective cohort study

Impact of Weight Loss on Metabolic Dysfunction Associated Steatohepatitis and Hepatic Fibrosis

PURPOSE OF REVIEW

This review highlights the impact of weight loss on metabolic dysfunction associated steatotic liver disease (MASLD), formally known as nonalcoholic fatty liver disease (NAFLD), and its progressive form of metabolic dysfunction associated steatohepatitis (MASH), formally known as nonalcoholic steatohepatitis (NASH). The effects of weight loss, as achieved through lifestyle modification, pharmacotherapy, bariatric surgery or endobariatric procedures on MASLD/MASH and hepatic fibrosis are discussed.

RECENT FINDINGS

Although foundational in the treatment of MASLD/MASH, weight loss through life-style modification is challenging for most patients to achieve and sustain long-term. In patients with MASLD/MASH, a multidisciplinary approach may facilitate success with lifestyle modification, individualized consideration of pharmacotherapies and/or surgical approaches that have potential to lend an improvement in MASLD/MASH. Effective and sustained weight loss improves hepatic steatosis, steatohepatitis and potentially hepatic fibrosis. Improvement in hepatic fibrosis can improve patient-related outcomes associated with complications of advanced hepatic fibrosis or cirrhosis in patients with MASLD/MASH. Identifying risk factors that influence MASLD/MASH and early implementation of therapeutic weight loss strategies may improve chronic liver injury and decrease risk for adverse clinical outcomes related to progressive hepatic fibrosis attributable to MASLD/MASH.

Tailored Model of Care for Patients with Metabolic Dysfunction-Associated Steatotic Liver Disease

Metabolic dysfunction-associated steatotic liver disease (MASLD), formerly known as nonalcoholic fatty liver disease (NAFLD), is increasing globally, creating a growing public health concern. However, this disease is often not diagnosed, and accurate data on its epidemiology are limited in many geographical regions, making it challenging to provide proper care and implement effective national plans. To combat the increasing disease burden, screening and diagnosis must reach a significant number of high-risk subjects. Addressing MASLD as a health care challenge requires a multidisciplinary approach involving prevention, diagnosis, treatment, and care, with collaboration between multiple stakeholders in the health care system. This approach must be guided by national and global strategies, to be combined with efficient models of care developed through a bottom-up process. This review article highlights the pillars of the MASLD model of care (MoC), including screening, risk stratification, and establishing a clinical care pathway for management, in addition to discussing the impact of nomenclature change on the proposed MoC.
