Clinical TrialA Prospective Clinical Trial Measuring the Effects of Cardiopulmonary Bypass Under Mild Hypothermia on the Inflammatory Response and Regulation of Cold-Shock Protein RNA-Binding Motif 3.
Therapeutic hypothermia during cardiac surgery has been widely used for neuroprotection and to attenuate the systemic inflammatory response due to cardiopulmonary bypass (CPB). Experimental data suggest that cold-shock protein RNA-binding motif 3 (RBM3), which is induced in response to hypothermia, plays a key role in hypothermia-induced organ protection. To date, investigation on RBM3 has been performed exclusively in vitro or in animal models, and the detection and regulation of RBM3 in human blood has not been investigated until now. ⋯ The use of CPB is still associated with a complex inflammatory response. RBM3 protein is measurable in blood samples of patients with significantly higher concentrations after cardiac surgery with CPB and mild-to-moderate hypothermia. RBM3 is a new candidate as a biomarker for therapeutic hypothermia and a possible new therapeutic target for organ protection.
