Role of Presepsin (sCD14-ST) and the CURB65 scoring system in predicting severity and outcome of community-acquired pneumonia in an emergency department
Method: A prospective, observational study was performed in an ED of an university teaching hospital from November 2011 to October 2012. A total of 359 patients with CAP and 214 patients with severe CAP (SCAP) were consecutively enrolled. Plasma Presepsin, lactate, serum PCT levels and leukocyte counts were measured and CURB65 score were calculated at admission enrollment.
Introduction: CD14 is one of the leukocyte differentiation antigens, and is present in macrophages, monocytes, granulocytes and their cell membranes. Presepsin, namely soluble CD14-subtype (sCD14-ST) is produced by circulating plasma proteases activating cleavage of soluble CD14 (sCD14). The aim of this study is to investigate the role of Presepsin and the CURB65 scoring system in the evaluation of severity and outcome of CAP in an ED.
