Exploring these alterations generally requires invasive methods, limiting data acquisition to subjects with enteropathies or undergoing bariatric surgery. We aimed to evaluate small intestine epithelial cell homeostasis in a cohort of men covering a wide range of adiposity and glucose homoeostasis statuses.<h4>Methods</h4>Plasma levels of citrulline, a biomarker of enterocyte mass, and I-FABP, a biomarker of enterocyte death, were measured by UHPLC‑MS and ELISA in 154 nondiabetic men and 67 men with a T2D diagnosis.<h4>Results</h4>Plasma citrulline was significantly reduced in men with insDiabetology & metabolic syndrome31https://www.ebi.ac.uk/biostudies/studies/S-EPMC7144049biostudies-literaturePlasma biomarkers of small intestine adaptations in obesity-related metabolic alterations.PMC7144049Couture PVeilleux ADrouin-Chartier JPTremblay AJLalande CfalsePlasma biomarkers of small intestine adaptations in obesity-related metabolic alterations.<h4>Background</h4>Evidence suggests that pathophysiological conditions such as obesity and type 2 diabetes (T2D) are associated with morphologic and metabolic alterations in the small intestinal mucosa.
