What this trial studies

This study aims to validate the cutoff value of interleukin-6 (IL-6) using the Symphony IL-6 test, which quantifies IL-6 levels from whole blood without the need for plasma separation. The Symphony IL-6 device provides rapid results, potentially allowing for point-of-care testing in emergency settings. Patients included in the study are those with severe or critical illness due to COVID-19, and the study will assess the effectiveness of the IL-6 measurement in identifying those at high risk for severe sepsis. The results could enhance early detection and management of severe sepsis in this patient population.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who are COVID-19 positive and exhibit signs of severe or critical illness.

Not a fit: Patients currently receiving anti-IL-6 treatment or corticosteroids may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved early detection and treatment of severe sepsis in COVID-19 patients.

How similar studies have performed: While the approach of using IL-6 as a biomarker has been explored, this specific validation study is novel in its application to COVID-19 related severe sepsis.
