Scores to predict steatotic liver disease - correlates and outcomes in older adults
Abstract
Metabolic dysfunction-associated steatotic liver disease (MASLD) is a significant cause of chronic liver disease globally, and the rising prevalence of MASLD is occurring in parallel with the global aging population. The use of non-invasive biomarker tools to rule-in or rule-out hepatic steatosis is important in large epidemiological studies in this field. While the Fatty Liver Index (FLI) is the best validated tool in older adults, not all studies will have the necessary parameters for steatosis identification. This retrospective post-hoc analysis of the ASPirin in Reducing Events in the Elderly (ASPREE) study involved 16,703 Australian adults aged ≥70 years. Using the FLI as the 'gold standard' index, we evaluated the correlation with other indices: the Dallas Steatosis Index (DSI), Framingham Steatosis Index, ZJU index (ZJU), Hepatic Steatosis Index (HSI), Lipid Accumulation Product (LAP), and Visceral Adiposity Index (VAI), as well as age- and sex-adjusted outcome measures including mortality, major adverse cardiovascular events (MACE), atrial fibrillation (AF), and persistent physical disability. Of the non-FLI indices, the DSI and FSI had the highest percentage of participants correctly classified as having MASLD (97.7% and 93.8% respectively). The FSI, LAP, and VAI were associated with MACE. The FSI and FLI were predictive of incident AF. The FLI, DSI, FSI, LAP and VAI were associated with physical disability. No MASLD score was associated with increased mortality.…
