Objective
This prospective cohort study aimed to describe the role and feasibility of the prognostic marker suPAR. Plasma suPAR levels were assessed by an immunoturbidimetric test as a prognostic marker together with the risk stratification tool, SOFA score, in patients admitted to a medical ICU.
Methods and patients
Plasma suPAR levels were measured on the turbidimetric assay suPARnostic® TurbiLatex kit after admission to the ICU in 237 unselected consecutive patients. The outcome was 28-day mortality.
Results
- Median suPAR levels were 8.0 ng/mL [25th-75th percentile 4.3-14.4], with lower levels in ICU survivors than non-survivors (6.7 vs. 11.6 ng/mL, p <0.001).
- CRP levels were not associated with survival.
- suPAR levels were higher in COVID-19, kidney disease, moderate-to-severe liver disease, and sepsis.
- ICU mortality increased by an odds ratio (OR) of 4.7 in patients with the highest compared to the lowest quartile suPAR.
-
ICU mortality was:
- 2% in patients with SOFA score ≤7 & suPAR ≤8 ng/ mL
- 17% in patients with a SOFA score ≤7 and >8 ng/ mL
Conclusion
suPAR was associated with ICU mortality and may offer the highest prognostic potential for risk stratification in moderately ill ICU patients (SOFA ≤7). suPAR was also a significant predictor for acute kidney injury occurrence.
