Observational Study
Association between acute gastrointestinal injury and biomarkers of intestinal barrier function in critically ill patients.
To assess the associations of biomarkers of intestinal barrier function and other clinical variables with acute gastrointestinal injury (AGI) grade, and of these clinical variables with mortality in critically ill patients. ⋯ AGI patients exhibit loss of gastrointestinal barrier function, and D-la could serve as a better marker of AGI grade than i-FABP or lipopolysaccharide.
