Addressing the High and Rising Global Burden of Metabolic Dysfunction‐Associated Steatotic Liver Disease (MASLD) and Metabolic Dysfunction‐Associated Steatohepatitis (MASH): From the Growing Prevalence to Payors' Perspective

BACKGROUND: The continuum of metabolic syndrome encompasses a spectrum of dysfunctions impacting obesity-linked insulin resistance, glucose homeostasis, lipid metabolism and pro-inflammatory immune responses. The global prevalence of metabolic diseases, including diabetes, chronic liver disease, cardiometabolic disease and kidney disease, has surged in recent decades, contributing significantly to population mortality. Metabolic dysfunction-associated steatotic liver disease (MASLD), formerly known as non-alcoholic fatty liver disease, is a leading cause of liver disease worldwide. MASLD poses a significant global health challenge with its rising prevalence, placing a substantial burden on healthcare systems, impacts patient well-being and incurs significant economic costs. Addressing MASLD requires a comprehensive understanding of its interconnected factors, including its prevalence, healthcare burden and economic implications. Lack of awareness, imprecise non-invasive diagnostic methods and ineffective preventive interventions are core components of the MASLD-related problem. AIM: The aim of this article was to summarise the global burden of MASLD from the payer's perspective. METHODS: We carried out a review of the global comprehensive burden of MASLD. These topics led to discussions and insights by an expert panel during the 7th Metabolic Continuum Roundtable meeting, which took place in November 2023. This meeting focused on the burden, patient-reported outcomes and health economics, from payor and societal perspectives, and aimed to identify opportunities for improving patient care, optimise resource allocation and mitigate the overall impact on individuals and society related to MASLD. During the roundtable, an emphasis emerged on the need for greater awareness and strategic deployment of diagnostic, therapeutic and preventative measures to address MASLD effectively. CONCLUSION: The global burden of MASLD is high and growing. Prioritising the prevention of metabolic dysregulation and timely therapeutic interventions can yield a holistic strategy to combat MASLD, its progression and potentially lower disease costs.
