Usefulness of presepsin (sCD14 subtype) measurements as a new marker for the diagnosis and prediction of disease severity of sepsis in the Korean population

초록

Purpose: Presepsin has recently emerged as a new useful sepsis marker, and our study is focused on the usefulness of presepsin as earlier detection and monitoring biomarker for sepsis comparing with other conventional biomarkers. Materials and methods: We compared the mean values of presepsin, procalcitonin, interleukin 6, and high-sensitivity C-reactive protein levels between infection group and noninfection group of study subjects and assessed whether the values decreased during treatment. Furthemore, we evaluated the diagnostic accuracy of presepsin in sepsis and compared the mean level of presepsin to the Acute Physiology and Chronic Health Evaluation III score and mortality rate on the 30th day. Results: Mean presepsin levels were significantly different between infection group and noninfection group (1403.47 pg/mL vs 239.00 pg/mL). During treatment, mean levels of presepsin decreased significantly, and in the receiver operating characteristic curve analysis, the area under curve value of presepsin was significantly higher than that of other biomarkers. The presepsin levels did not correlate significantly with Acute Physiology and Chronic Health Evaluation III scores and mortality rates on the 30th day. Conclusions: Presepsin showed significantly higher values in infection group than in noninfection group. The diagnostic accuracy of presepsin was higher than other conventional biomarkers. For early diagnosis and treatment of bacterial sepsis, presepsin could be a more useful marker than the other markers. (C) 2014 Elsevier Inc. All rights reserved.
