Prognostic performance of pancreatic stone protein in critically ill patients with sepsis.

To assess the prognostic value for 28-day mortality of PSP in critically ill patients with sepsis. 122 consecutive patients with sepsis were enrolled in this study. Blood samples were collected on admission and day 2. On admission, the combination of PSP and lactate achieved an area under the receiver operating characteristic (AUC-ROC) of 0.796, similar to sequential organ failure assessment score alone (AUC-ROC: 0.826). On day 2, PSP was the biomarker with the highest performance (AUC-ROC: 0.844), although lower (p = 0.041) than sequential organ failure assessment score (AUC-ROC: 0.923). The combination of PSP and lactate and PSP alone, on day 2, have a good performance for prognosis of 28-day mortality and could help to identify patients who may benefit most from tailored intensive care unit management.
