ABSTRACT 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.

Abstract Purpose Pancreatogenic diabetes refers to diabetes mellitus (DM) that develops in the setting of a disease of the exocrine pancreas, including pancreatic ductal adenocarcinoma (PDAC) and chronic pancreatitis (CP). We sought to evaluate whether a blunted nutrient response of pancreatic polypeptide (PP) can differentiate these DM subtypes from type 2 DM (T2DM). Methods Subjects with new-onset DM (<3 years’ duration) in the setting of PDAC (PDAC-DM, n = 28), CP (CP-DM, n = 38), or T2DM (n = 99) completed a standardized mixed meal tolerance test, then serum PP concentrations were subsequently measured at a central laboratory. Two-way comparisons of PP concentrations between groups were performed using Wilcoxon rank-sum test and analysis of covariance while adjusting for age, sex, and body mass index. Results The fasting PP concentration was lower in both the PDAC-DM and CP-DM groups than in the T2DM group (P = 0.03 and <0.01, respectively). The fold change in PP at 15 minutes following meal stimulation was significantly lower in the PDAC-DM (median, 1.869) and CP-DM (1.813) groups compared with T2DM (3.283; P < 0.01 for both comparisons). The area under the curve of PP concentration was significantly lower in both the PDAC-DM and CP-DM groups than in T2DM regardless of the interval used for calculation and remained significant after adjustments. Conclusions Fasting PP concentrations and the response to meal stimulation are reduced in new-onset DM associated with PDAC or CP compared with T2DM. These findings support further investigations into the use of PP concentrations to characterize pancreatogenic DM and to understand the pathophysiological role in exocrine pancreatic diseases (NCT03460769).
