Summarized by Masters of Longevity from Frontiers - Health.
A bedside test-focused article examining a rapid LPS-stimulated TNF-α point-of-care assay for early immune-risk stratification in emergency patients; it previews workflow, diagnostic intent, and study design to assess feasibility and clinical value.
Key Takeaways
- Researchers used a bedside LPS-induced TNF-α release assay producing results under three hours to identify innate immune hyporesponsiveness.
- A predefined hyporesponsive threshold corresponded to stimulated TNF-α below approximately 200–250 pg/mL indicating an endotoxin-tolerance phenotype.
- The study enrolled ED adults with suspected infection and NEWS2 ≥3 to estimate prevalence and diagnostic performance against Sepsis-3 adjudication within 24 hours.
