Diagnostic value and prognostic evaluation of presepsin for acute respiratory distress syndrome (ARDS) / 复旦学报（医学版）

ABSTRACT

Objective To assess the diagnostic and prognostic value of measuring presepsin in patients with acute respiratory distress syndrome (ARDS).Methods Plasma prsepsin was collected from 81 patients with ARDS,27 patients with cardiogenic pulmonary edema (CPE) and 20 healthy volunteers at enrollment.Levels of presepsin were measured using the PATHFAST(R) analysis system based on a chemiluminescent enzyme immunoassay (CLEIA).The differences of plasma prsepsin were compared between different groups.The 28-day mortality were followed in ARDS patients,and the characteristics of the surviors and non-surviors were compared.Results ARDS patients had significantly higher median levels of presepsin compared to CPE patients [926.89 (485.41-2 662.32)pg/mL vs.376.21 (247.16-568.52) pg/mL,P＜0.001] at enrollment.The difference between infected and non-infected ARDS patients did not showed statistical significance [(934.74 (456.44-3 322.51) pg/mL vs.798.12 (485.41-2 561.40) pg/mL,P--0.079).In ARDS patients,the presepsin levels of non-survivors was significantly higher than that of survivors [3 158.3 (963.91-4 489.33) pg/mL vs.729.09 (398.05-1 467.24) pg/mL,P＜0.001],and multivariate Logistic regression showed that presepsin (OR =1.51,P =0.027) was the independent predictor for 28-day mortality in ARDS patients with acute lung injury (ALI).Conclusions Presepsin was an effective indicator in diagnosing ARDS,and it also was a strong prognostic marker for short-term mortality in ARDS.
