Abstract

Background and Aims: Several biomarkers are used in the diagnosis of bacteremia. Procalcitonin (PCT) is more specific than other biomarkers in differentiating bacterial and nonbacterial inflammation. It was aimed to evaluate the diagnostic and prognostic value of PCT in bacteremic patients in Intensive Care Unit (ICU). Materials and Methods: A total of 156 patients diagnosed with noninfectious systemic inflammatory response syndrome, sepsis, and severe sepsis/septic shock in ICU between December 2014 and July 2015 were evaluated in this prospective cohort study. Results: The study group consisted of 64 (41%) bacteremic patients and the control group consisted of 92 (59%) nonbacteremic patients. The overall mortality rate was 60.3%. Although PCT levels in the bacteremic group (11.9 ± 21.5 ng/dL) were higher than nonbacteremic group (5.9 ± 11.5 ng/dL), this difference was not significant (P = 0.168). The mean levels of PCT in bacteremic patients with Gram-negative bacteria were 16.3 ± 27.6 ng/dL, whereas Gram-positive bacteria were 7.3 ± 10.7 ng/dL (P = 0.145). The mean PCT levels were significantly higher in nonsurvivors compared to survivors (10.1 ± 18.0 vs. 5.7 ± 13.7 ng/dL; P < 0.001). Conclusions: PCT may be an effective biomarker for diagnosing sepsis and predicting disease severity and mortality. There is a need for further well-designed studies to confirm the diagnostic and prognostic value of PCT in septic patients in critical care.
