Plasma biomarkers of gut injury in cases and controls. Blood was drawn from patients in the 48 h preceding a bacteremia event. Plasma levels of (A) I-FABP, (B) TFF3 and (C) citrulline did not significantly differ between patients with enterococcal bacteremia as compared to patients with CoNS bacteremia. Dashed lines represent threshold values for biomarkers: elevated I-FABP > 100 pg/ml, elevated TFF3 > 8.3 ng/ml, and decreased citrulline < 20 μmol/l. I-FABP intestinal fatty acid-binding protein, TFF3 trefoil factor-3, CoNS Coagulase-negative Staphylococci
