Plasma levels of intestinal fatty acid-binding protein and citrulline are not associated with severe upper gastrointestinal ischemic lesions after out-of-hospital cardiac arrest: an ancillary study of the ENTRACT trial.

ABSTRACT:

Background

Acute intestinal injury plays a major role in the pathophysiology of the post-cardiac arrest (CA) syndrome. Citrulline and intestinal fatty acid-binding protein (I-FABP) are associated with mesenteric ischemia but there is paucity of data regarding their association with upper gastrointestinal tract injury.

Methods

We conducted an ancillary analysis of the prospective and multicentric ENTRACT study, in which all patients who remained mechanically ventilated during the first 5 days after out-of-hospital CA underwent an esophago-gastro-duodenoscopy. Patients with available biobank were enrolled and plasma citrulline and I-FABP and urinary I-FABP were measured to assess their association with the severity of upper gastrointestinal tract lesions.
