ABSTRACT
BACKGROUND: The relationship between the Advanced Lung Cancer Inflammation Index (ALI) and all-cause mortality in patients with Metabolic Dysfunction-Associated Steatohepatitis and Metabolic-Associated Alcoholic Liver Disease and other combination etiology of steatosis (MASLD/MetALD & Mixed Etiology Steatosis) is not well-understood. Current evidence is insufficient to establish this association, yet it holds critical importance for healthcare and public health. Research into the link between ALI and all-cause mortality in MASLD/MetALD & Mixed Etiology Steatosis remains a topic of interest.
OBJECTIVE: This study investigated the association between ALI and all-cause mortality in MASLD/MetALD & Mixed Etiology Steatosis patients, and explored the clinical significance of this association.
METHODS: We conducted a cohort study using data from the National Health and Nutrition Examination Survey between 2007 and 2018, involving 4502 adult participants with MASLD/MetALD & Mixed Etiology Steatosis in the United States. Data collected included age, sex, race, education, marital status, poverty-to-income ratio, alanine aminotransferase levels, aspartate aminotransferase levels, high-density lipoprotein cholesterol, total cholesterol, diabetes mellitus, coronary heart disease, and stroke. Cox proportional hazards regression models were used to assess the relationship between ALI and all-cause mortality, with follow-up through 31 December 2019, from the National Center for Health Statistics.
RESULTS: The study found that ALI in patients was significantly negatively associated with the risk of all-cause mortality in U.S. adults with MASLD/MetALD & Mixed Etiology Steatosis. Participants with higher ALI levels had a significantly lower risk of all-cause mortality compared to those with lower ALI levels. After full adjustment, moderate ALI levels were associated with a 42% reduced risk (hazard ratio [HR]: 0.58, 95% confidence interval [CI]: 0.41-0.81), and high ALI levels were associated with a 49% reduced risk (HR: 0.51, 95% CI: 0.35-0.73) of all-cause mortality. No significant interactions were observed in subgroup analyses (P > 0.05).
CONCLUSION: This study suggested that high ALI levels are associated with a reduced risk of all-cause mortality in MASLD/MetALD & Mixed Etiology Steatosis patients. These findings may have important clinical implications for healthcare providers managing MASLD/MetALD & Mixed Etiology Steatosis patients, emphasizing the potential role of ALI as a prognostic marker for all-cause mortality.
