FABP2 and systemic inflammatory response syndrome: I-FABP is involved in the uptake and transport of long chain fatty acids from the intestinal lumen.[22] I-FABP is mainly expressed in the intestinal villi, where ischemic injury first occurs, so it might be an early and useful marker for mucosal compromise or injury of the intestine as well as systemic inflammatory response syndrome.[23] Thus, we will use I-FABP as a diagnostic marker for evaluating gut wall integrity loss and inflammation.
