Mesenteric ischemia-reperfusion: an overview of preclinical drug strategies

Mesenteric ischemia is a surgical emergency caused by a transient reduction in blood perfusion to the bowel. Despite accounting for only 0.1% of hospital admissions and 1-2% of gastrointestinal diseases, its elusive symptoms often lead to dramatically high morbidity and mortality rates. The complex cascade of inflammatory events and mediators triggered by mesenteric ischemia-reperfusion (I/R) accounts for the plethora of proposed pharmacological targets and for the current lack of an efficacious drug strategy for its management. It is hoped that a deeper understanding of its pathogenesis and the preclinical therapeutic strategies identified to date and described herein will improve the translation into the clinical setting of the pharmacological armamentarium against a life-threatening disorder that is currently mainly managed surgically.
