Abstract

The present invention relates to methods, monitors and systems, useful, for example, for advanced detection of sepsis in a subject.

Claims

1. A method comprising the steps of:

(a) measuring at a plurality of time points, prior to laboratory confirmation of a clinically significant infection causative of sepsis, an amount of a compound according to formula (I)

2. The method of claim 1, wherein R is saturated acyl.

3. The method of claim 1, wherein R is C₁₄-C₂₂ acyl.

4. The method of claim 1, wherein R is C₁₆-C₂₀ acyl.

5. The method of claim 1, wherein R is C₁₆-C₁₈ acyl.

6. The method of claim 1, wherein R is C₁₆ saturated acyl.

7. The method of claim 1, wherein R is C₁₈ saturated acyl.

8. The method of claim 1, wherein R is unbranched C₁₆-C₁₈ acyl.

9. The method of claim 1, wherein R is palmitoyl.

10. The method of claim 1, wherein R is stearoyl.

11. The method of claim 1, wherein the amount of a compound according to formula (I) is measured 12, 24, 36 or 48 hours prior to the onset of sepsis in said SIRS-positive patient.

12. The method of claim 1, wherein the one or more biomarkers comprise procalcitonin.

13. The method of claim 12, wherein the one or more clinical markers of the SIRS-positive subject comprises respiratory rate and temperature.

14. The method of claim 1, wherein the one or more clinical markers of the SIRS-positive subject comprises respiratory rate and temperature.

15. The method of claim 1, wherein the one or more biomarkers in fluid or tissue of the SIRS-positive subject comprises TRAF-interacting protein with a forkhead-associated domain (TIFA), extra-hepatic arginase (ARG2), carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1), and human leukocyte antigen—

antigen D-related alpha chain (HLA-DRA).

16. The method of claim 1, wherein the one or more clinical markers of the SIRS-positive subject comprises respiratory rate or temperature, and the one or more biomarkers comprises HLA-DRA.
