BACKGROUND: Sepsis remains a major cause of mortality in critically ill patients. This study aimed determine whether presepsin is a predictor of septic AKI, ARDS, DIC, and shock.
METHODS: A total of 83 adult patients diagnosed with sepsis were prospectively examined. Presepsin values were measured immediately after ICU admission and on Days 2, 3, and 5 after ICU admission. Glasgow Prognostic Score (GPS), neutrophil to lymphocyte ratio, platelet to lymphocyte ratio, Prognostic Index, and Prognostic Nutritional Index were also examined at baseline. For category classification, total scores were calculated (hereafter, "inflammation-presepsin scores [iPS]") as follows: a score of 1 was assigned if the presepsin value and inflammation-based prognostic scores at baseline were above cut-offs determined by receiver operating characteristic (ROC) curve analysis for 28-day mortality; a score of 0 was assigned if they were below the cut-offs (total score range, 0 - 2 points). Presepsin values, inflammation-based prognostic scores and iPS were compared between patients with septic AKI, ARDS, DIC, or shock and those without these disorders.
RESULTS: ROC curve analyses identified the following variables as predictors: presepsin on Days 1 and 2 for septic AKI; presepsin on Days 1 - 3 and iPS-GPS for septic ARDS; and presepsin on Day 2 and Δpresepsin (Day 2 - Day 1) for septic DIC. Multivariate analysis revealed presepsin on Day 2 to be a predictor of septic DIC.
CONCLUSION: Presepsin is a predictor of septic AKI, ARDS, and DIC. Combining presepsin values with GPS improved the specificity for predicting septic ARDS relative to using baseline presepsin values alone.
