| Cohort | Between November 1, 2012 and February 28, 2014, all consecutive adult non-neutropenic patients with SAC on ICU admission and an expected stay of ≥ 7 days were included in a prospective, cohort, observational, and multicenter study. A prospective study of 233 non-neutropenic patients with SAC on ICU admission and expected stay ≥ 7 days. CAGTA (cutoff positivity ≥ 1/160), BDG (≥80, 100 and 200 pg/mL), mannan-Ag (≥60 pg/mL), mannan-Ab (≥10 UA/mL) were measured twice a week, and Candida DNA only in patients treated with systemic antifungals. |

| Disease Introduction Mechanism | Accurate and timely diagnosis of invasive candidiasis (IC) from the patient’s perspective and to optimize antifungal therapy in the intensive care unit (ICU) setting remains a topic of great interest. The use of single or combined biomarkers, such as (1→ 3)-ß-D-glucan (BDG), Candida albicans germ tube antibody (CAGTA), mannan antigen (mannan-Ag), anti-mannan antibodies (mannan-Ab), and polymerase chain reaction (PCR) detection of Candida DNA has received increasing at- tention, but the appropriate incorporation into clinical practice remains controversial. We investigated the performance of these five tests, alone and in combin- ation, for discriminating IC in critically ill patients with severe abdominal conditions (SAC). |
