Plasma Levels of Danger-Associated Molecular Patterns in Young Children After Cardiac Surgery Under Cardiopulmonary Bypass

NCT04423523 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 88

No results posted yet for this study

Summary

The investigators have previously reported that cardiac surgery with cardiopulmonary bypass (CPB) in young infants induced a drastic reduction in mHLA-DR (Human Leucocyte Antigen) expression, which represents one of innate immune mediator. Danger-Associated Molecular Patterns (DAMPs) can elicit immune response and may subsequently induce an immune-suppressed state. We hypothesize that analyzing the proteomic and the whole blood transcriptomic response after cardiac surgery would provide new insights into the pathophysiological mechanisms of CPB-related inflammatory response.
