Neutrophil-derived ROS as a rapid functional biomarker: diagnostic and prognostic performance of the Leukocyte ImmunoTest in infection and sepsis
Clinical Report: Neutrophil-Derived Reactive Oxygen Species as a Rapid Functional Indicator
Overview
The Leukocyte ImmunoTest (LIT) quantifies neutrophil-derived reactive oxygen species (ROS). LIT values correlate with disease severity and mortality risk.
Background
Sepsis is a critical condition with high morbidity and mortality, necessitating timely diagnosis and intervention. Traditional biomarkers often fail to reflect the dynamic immune response in sepsis.
Data Highlights
Group
Median LIT (RLU)
Controls
470
Infection
882
Sepsis
2466
Key Findings
Median LIT values increased significantly across diagnostic groups: controls (470 RLU), infection (882 RLU), and sepsis (2466 RLU).
LIT demonstrated high diagnostic performance for infection (AUC: 0.94) and sepsis (AUC: 0.86).
Higher LIT values were independently associated with increased mortality (HR: 1.6).
LIT performance was comparable to established biomarkers such as C-reactive protein (CRP) and procalcitonin (PCT).
Multicenter studies are needed to further evaluate LIT's role in sepsis management.
Clinical Implications
LIT may serve as a tool for assessment of immune activation in patients suspected of infection or sepsis.
Conclusion
The Leukocyte ImmunoTest is a diagnostic tool for sepsis, warranting further investigation.
