Background: Intestinal fatty acid–binding protein (I-FABP), a biomarker of enterocyte injury, has been reported to be a diagnostic marker of intestinal ischemia and a prognostic marker in critically ill patients. However, the kinetics of I-FABP in renal failure patients is unknown. We sought to identify I-FABP levels in patients with chronic kidney disease (CKD) and end-stage kidney disease (ESKD) on hemodialysis (HD) and to identify the manner in which the I-FABP levels change. Materials and methods: Adult patients who were admitted for elective cardiac surgery with either normal renal function (NRF), CKD, or ESKD on HD were enrolled. Serum I-FABP levels in NRF and CKD patients and in ESKD patients before and after HD were determined. Results: A total of 124 patients were evaluated: 47 NRF, 53 CKD, and 24 ESKD. The I-FABP levels of the CKD patients and pre-HD ESKD patients were significantly higher than those of the NRF patients (P = 0.018 and P <0.001, respectively). I-FABP levels were significantly negatively correlated with the estimated glomerular filtration rate in NRF and CKD patients (Spearman's ρ = −0.313, P = 0.002). In addition, I-FABP levels in ESKD patients were significantly lower after HD than those before HD (P <0.001). Conclusions: I-FABP levels in CKD and pre-HD ESKD patients were significantly higher than those in NRF patients. In addition, I-FABP was significantly eliminated by HD in patients with ESKD. Clinicians and researchers should consider this aspect of I-FABP when using it as a diagnostic and prognostic marker in patients with renal insufficiency.
