What this trial studies

The Symphony IL-6 study aims to establish a cutoff value for interleukin-6 (IL-6) levels in patients at high risk of severe sepsis due to COVID-19 or influenza infections. This observational study utilizes the Symphony IL-6 device, which quantifies IL-6 from whole-blood specimens without the need for plasma separation. The device provides rapid results, allowing for timely clinical decision-making in emergency settings. By determining the IL-6 cutoff, the study seeks to improve the identification of patients who may develop severe sepsis.

Who should consider this trial

Good fit: Ideal candidates include adults aged 22 and older who are confirmed positive for COVID-19 or influenza and have had a CRP test.

Not a fit: Patients receiving anti-IL-6 treatment or those with hemolyzed blood specimens will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance early detection and management of severe sepsis in at-risk patients, potentially improving outcomes.

How similar studies have performed: Other studies have shown promise in using IL-6 as a biomarker for severe sepsis, suggesting that this approach may be effective.
