Abstract

Cardiopulmonary bypass (CPB) leads to systemic and cardiac inflammation. Although the intraoperative blood measurement of some inflammatory cytokines has been recognized as an useful tool in clinical setting, postoperative management still represents a major problem; hence, knowledge about additional possible mediator(s) in time of this process would potentially turn in a clinical benefit. CXCL10 has been shown to be involved in cardiac immune-inflammatory processes. Herein, we aimed to investigate whether and how this chemokine could be a possible early mediator and indicator of inflammation development during CPB. Since cardiac, endothelial and immune cells are all sources of CXCL10, our purpose was also to investigate in vitro CXCL10 secretion pattern in time by those cell types. CXCL10 level was higher in CPB patients before surgery as compared to healthy subjects; CXCL10 level raises earliest in serum of CPB patients and in isolated cardiomyocytes under inflammatory stimuli as compared to other cytokines. CXCL10 might represent a critical early factor in mediating systemic and local cardiac inflammatory response in subjects undergoing CPB, offering opportunity for future monitoring or therapeutic interventions.
