ABSTRACT Objective: To evaluate whether PCT levels could be used to distinguish among different bacterial and fungal etiologies in patients with documented bloodstream infection (BSI). Patients and methods: Monocentric retrospective cohort study on patients admitted to the Fondazione Policlinico Gemelli Hospital between December 2012 and November 2015 with BSI. Those who had undergone PCT determination within 48 hours of when the first positive blood culture was sampled were included in the study. Results: Four hundred and one patients were included into the study. Both the 24h and 48h PCT values were significantly higher in patients with Gram negative (GN) BSI than in those with Gram positive (GP) or candida BSI (p at ANOVA = 0.003). A PCT value of >1 ng/ml was found in 31.5% of patients with GN BSI. Less than 7% of people with candida BSI had PCT level of >1 ng/ml. At multivariable regression analysis, GN BSI, septic shock, and plasma creatinine were significantly correlated with PCT values. Conclusions: PCT may be of value in distinguishing GN BSI from GP and fungal BSI and PCT values of >1 ng/ml could be used to prevent unnecessary antifungal treatment.
