Measuring immune response in infants after heart surgery

Plasma Levels of Danger-Associated Molecular Patterns (DAMPs) in Young Children After Cardiac Surgery Under Cardiopulmonary Bypass (IMMUNOPED 2)

Observational Nantes University Hospital · NCT04423523

This study looks at how heart surgery affects the immune system in young infants by checking certain proteins in their blood before and after the operation.

What this trial studies

This observational study investigates the release of Danger-Associated Molecular Patterns (DAMPs) in young infants undergoing cardiac surgery with cardiopulmonary bypass (CPB). Researchers will measure plasma levels of specific proteins at various time points before and after surgery to assess the impact of CPB on immune suppression. The study aims to understand how excessive DAMP release may contribute to an immune-suppressed state in these patients. In vitro experiments will also be conducted to evaluate the direct effects of DAMPs on immune function.

Who should consider this trial

Good fit: Ideal candidates are infants aged 3 months or younger who are undergoing cardiac surgery with CPB.

Not a fit: Patients who are not undergoing cardiac surgery or are older than 3 months may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management of immune suppression in infants after cardiac surgery.

How similar studies have performed: While the specific approach of measuring DAMPs in this context may be novel, related studies have indicated that understanding immune responses in surgical patients can lead to better outcomes.
