Identifying infections after major surgery using gene expression changes

Changes in Host Gene Expression to Differentiate Between Systemic Inflammation and Infection After Major Surgery

St. Antonius Hospital · NCT06116656

This study is testing if changes in certain genes in the blood can help doctors tell if adult patients who had major surgery have an infection or just a normal inflammatory response.

What this trial studies

This observational study aims to validate specific gene signatures that can differentiate between postoperative infections and non-infected systemic inflammatory response syndrome (SIRS) in adult patients undergoing major noncardiac surgery. By analyzing blood samples taken at various time points post-surgery, researchers hope to improve diagnostic accuracy and timely interventions. The study involves a multicenter approach, collecting blood samples to assess changes in host gene expression related to infection risk.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old undergoing major noncardiac surgery with a risk of infection greater than 20%.

Not a fit: Patients under 18 years old, those undergoing emergency surgery, or individuals unable to provide informed consent may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more accurate and timely diagnoses of postoperative infections, potentially improving patient outcomes.

How similar studies have performed: Other studies have explored gene expression for diagnostic purposes, but this specific approach to differentiate between SIRS and infection post-surgery is relatively novel.
