Abstract
Per- and polyfluoroalkyl substances (PFAS) are persistent organic pollutants previously associated with elevated liver enzymes in human cohorts and steatotic liver disease in animal models. We aimed to evaluate the associations between PFAS exposures, and liver enzymes and vibration controlled transient elastography (VCTE) biomarkers of metabolic dysfunction associated steatotic liver disease (MASLD) in adult National Health and Nutrition Examination Survey (NHANES) 2017 to 2018. VCTE was determined by FibroScan. Serum PFAS (n = 14), measured by mass spectrometry, were analyzed individually and by principal component (PC). Univariate and multivariable associations were determined between PFAS exposures and liver disease outcome variables: alanine aminotransferase (ALT), controlled attenuation parameter (CAP), liver stiffness measurement (LSM), FibroScan-based Score (FAST), using R. About 1,400 participants including 50% women with a mean age of 48 ± 19 years and a mean BMI of 29 ± 7 kg/m2 were analyzed. Four PFAS clustered to PC1, whereas 3 PFAS clustered to PC2. PC1 was significantly associated with ALT (β = 0.028), CAP (β = 0.041), LSM (β = 0.025), and FAST (β = 0.198) in univariate analysis. Individual PFAS exposures were oftentimes inversely associated with these measurements in multivariate analysis. In adult NHANES 2017-2018, PFAS may not be a significant burden for MASLD, because of the inconsistent associations between the environmental PFAS exposures and biomarkers of liver steatosis, inflammation, and fibrosis. More data are required to better understand the relationships between PFAS exposures and liver disease.
期刊介绍：
The mission of Toxicological Sciences, the official journal of the Society of Toxicology, is to publish a broad spectrum of impactful research in the field of toxicology.
The primary focus of Toxicological Sciences is on original research articles. The journal also provides expert insight via contemporary and systematic reviews, as well as forum articles and editorial content that addresses important topics in the field.
The scope of Toxicological Sciences is focused on a broad spectrum of impactful toxicological research that will advance the multidisciplinary field of toxicology ranging from basic research to model development and application, and decision making. Submissions will include diverse technologies and approaches including, but not limited to: bioinformatics and computational biology, biochemistry, exposure science, histopathology, mass spectrometry, molecular biology, population-based sciences, tissue and cell-based systems, and whole-animal studies. Integrative approaches that combine realistic exposure scenarios with impactful analyses that move the field forward are encouraged.
