Abstract

Background and objective: To evaluate the clinical usefulness of serum intestinal fatty acid binding protein (I-FABP) and D-lactate measurements in the early diagnosis of acute intestinal ischemia.

Methods: A total of 272 patients with a clinical diagnosis of acute abdomen were recruited for this trial over a 24-month period, and 37 healthy people were included in the study as controls. Serum I-FABP and D-lactate levels were measured by an enzyme-linked immunosorbent assay and compared in patients with intestinal ischemia vs. non-intestinal ischemia.

Results: Of the 272 patients, 39 were diagnosed with intestinal ischemia and 233 were diagnosed with other cause of acute abdomen. The mean serum I-FABP and D-lactate levels in the patients with intestinal ischemia were 149.74±57.81ng/mL and 52.73±26.46 ug/mL, respectively, and were significantly higher compared with patients with non-intestinal ischemia (36.78±11.25ng/mL and 15.58±5.17 ug/mL, respectively) and with levels in the healthy control group (8.33±6.25 ng/mL and 5.47±1.64 ug/mL, respectively). Area under the curve for I-FABP and D-lactate were 0.85 and 0.69, and cut-off values of 93.07 ng/mL and 34.28 ug/mL, respectively.

Conclusion: Serum I-FABP and D-lactate can improve the diagnosis of intestinal ischemia in patients with acute abdomen who are at risk.
