Validation of IL-6 levels to predict mortality in sepsis patients in the ICU

Multicenter Symphony IL-6 Monitoring Sepsis ICU Validation Study

Observational Bluejay Diagnostics, Inc. · NCT06654895

This study is testing if measuring a certain level of a protein called IL-6 in the blood can help doctors predict which ICU patients with sepsis are at higher risk of dying within 28 days.

What this trial studies

This observational study aims to validate a specific concentration of interleukin-6 (IL-6) that can predict 28-day mortality in patients diagnosed with sepsis or septic shock who are admitted to the ICU. By measuring IL-6 levels in plasma samples collected within 24 hours of diagnosis, the study seeks to establish a reliable cutoff that can aid in risk stratification for these critically ill patients. The findings could enhance clinical decision-making and improve patient outcomes in intensive care settings.

Who should consider this trial

Good fit: Ideal candidates include adult patients aged 22 and older who are diagnosed with sepsis or septic shock and are admitted or intended to be admitted to the ICU.

Not a fit: Patients who are prisoners or unable to provide informed consent will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a crucial tool for predicting mortality risk in sepsis patients, potentially leading to better-targeted treatments.

How similar studies have performed: Other studies have explored the role of IL-6 in sepsis, but this specific validation approach is novel and has not been extensively tested.
