Evaluation of soluble CD14 subtype (presepsin) in burn sepsis

Backgrou nd: Diagnosing sepsis is difficult in burn patients because of the inflammatory mediators that alter postbum metabolic profile. Here, we compare a new marker presepsin with procalcitonin (PCT), c-reactive protein (CRP) and white blood cell (WBC) in diagnosis and follow up of sepsis in burn patients. Methods: Patients admitted to burn center of our institute were prospectively investigated. Presepsin, PCT, CRP and WBC levels were measured at admission and every 6 h for first day and daily thereafter. At all timing samples, patients were classified as sepsis or non-sepsis according to the current American Burn Association Consensus Criteria (ABA) 2007. Result: 37 adult patients were evaluated. A total data of 611 time points were supplied. Sepsis time points differ significantly from non-sepsis in presepsin (p < 0.0001), PCT (p = 0.0012) and CRP (p < 0.0001) levels. Non-surviving patient results differ significantly from survivors in presepsin (p < 0.0001), PCT (p = 0.0210) and CRP (p = 0.0008). AUC-ROC % values for diagnosing sepsis were 83.4% for presepsin, 84.7% for PCT, 81.9% for CRP and 50.8% for WBC. Sepsis patients had significantly different presepsin, CRP and WBC but not PCT levels on their first day of sepsis compared to previous days. Conclusion: Plasma presepsin levels have comparable performance in burn sepsis. (c) 2013 Elsevier Ltd and ISBI. All rights reserved.
