Enterocyte Injury and Acute Gastrointestinal Dysfunction in Critical Illness
500 participantsStarted 2026-03-01
Plain-language summary
Acute gastrointestinal injury (AGI) is a common but not fully understood organ dysfunction in critically ill patients. Current AGI grading systems rely primarily on clinical presentation and feeding tolerance, which are inherently subjective and may not accurately reflect the underlying biological severity of intestinal damage.
Intestinal fatty acid-binding protein (I-FABP) is a protein expressed almost exclusively in the cytoplasm of mature small intestinal epithelial cells. In cases of ischemia, inflammation, or mechanical injury, I-FABP is rapidly released into the bloodstream and subsequently excreted in the urine. These characteristics make I-FABP a highly specific biomarker for intestinal epithelial cell injury and intestinal ischemia.
A prospective study combining paired blood and urine I-FABP measurements, standardized AGI assessment, and careful consideration of surgical status was conducted to elucidate the role of intestinal epithelial cell injury in acute gastrointestinal dysfunction.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
