Summary

* Testing the association between circulating candidate proteins and the level of vascular leakage for three distinct forms of circulatory failure: cardiogenic shock, septic shock, and post-resuscitation syndrome. * Describing immuno-inflammatory profiles associated with massive vascular leakage during those three forms of circulatory failure in humans

Detailed description

Circulatory shocks are responsible for one third of intensive care unit (ICU) admissions (20,000 patients per year in France) and are associated with 40% mortality \[1,2\]. Vascular hyperpermeability (also called vascular leakage) is a major feature of circulatory failure. During systemic inflammatory response syndrome (SIRS), massive vascular leakage affects macro and micro-circulation, and participates in the development of multiple organ failure \[1,3\]. Accordingly, fluid balance (the difference between fluid input and output) correlates independently with mortality during both septic and cardiogenic shock \[4-7\] and controlling capillary leakage was highly beneficial in numerous animal models of circulatory failure \[8-10\]. However, the determinants of vascular leakage remain poorly understood in humans. The purpose of this study is to evaluate the link between circulatory levels of several proteins and the level of vascular leakage, in three distinct types of circulatory shocks.
