Summary
Elevated interleukin-6 (IL-6) levels are linked to increased COVID-19 severity and mortality. Dynamic IL-6 changes may predict lung injury, guiding future patient treatment strategies.
Area of Science:
- Immunology
- Infectious Diseases
- Critical Care Medicine
Background:
- Interleukin-6 (IL-6) is a proinflammatory cytokine implicated in COVID-19 severity and mortality.
- The prognostic value of dynamic IL-6 changes for lung injury in COVID-19 remains unclear.
Purpose of the Study:
- To determine if IL-6 levels correlate with COVID-19 severity and mortality.
- To investigate the predictive potential of dynamic IL-6 changes for lung injury in COVID-19 patients.
Main Methods:
- Retrospective analysis of 728 adult COVID-19 patients.
- Data extracted from electronic medical records.
- Statistical analyses including Cox regression and logistic regression.
Main Results:
- Higher mortality observed in patients with elevated IL-6 (5% vs 0.16%).
- Elevated IL-6 independently predicted disease severity (aOR 3.56) and mortality (aHR 10.39).
- Dynamic IL-6 changes mirrored computed tomography (CT) scores, peaking around days 22-24.
Conclusions:
- Increased IL-6 is an independent risk factor for COVID-19 severity and in-hospital mortality.
- Dynamic IL-6 monitoring may predict lung injury progression in COVID-19.
- Findings can inform clinical management of COVID-19 patients.
