Serum procalcitonin levels in critically ill patients colonized with Candida spp: new clues for the early recognition of invasive candidiasis?

Objective Invasive candidiasis (IC) outcomes in intensive care units (ICUs) could be improved by the early administration of antifungals. The Candida Score (CS) prediction rule has been proposed for the selection of patients who could develop IC. Procalcitonin (PCT) levels allow prompt identification of sepsis, but their behavior in the setting of IC is unclear. We hypothesize that PCT could be helpful in the early diagnosis of IC in patients with Candida sp. colonization.
