The combination of acute phase marker monitoring and the "T2Candida" assay (name of the test) will represent an acceleration of the identification of the causative agent of mycotic infection, a significant improvement in the specificity and positive predictive value of this strategy in the diagnosis of invasive candidiasis and candidemia in ICU patients, thereby improving the clinical condition of patients and reducing the cost of specific antifungal therapy.
Speed of response in the treatment of sepsis is crucial for the patient. The time from the collection of a positive haemoculture to the identification of the causative agent of sepsis is around 2 days; therefore, physicians in intensive care units deploy combined empiric antibiotic and antifungal therapy immediately when acute phase markers such as procalcitonin, interleukin-6, Presepsin, C-reactive protein are elevated. A new acute phase marker is lipopolysaccharide-binding protein, which, together with Presepsin, appears to be a suitable marker to distinguish invasive candida infections from bacterial infections. But its kinetics needs to be further analyzed. At the same time, the causative agent of sepsis, G-/G+ bacteria or yeast, must be identified as soon as possible. Haemoculture and culture of the established drain is the gold standard, but the disadvantage is the low sensitivity and the time delay to obtain the result. It is therefore advisable to combine haemoculture with molecular biology-based tests that can identify the causative organism within hours. Conversely, the disadvantage of these tests is that they identify only the most common sepsis pathogens and do not determine susceptibility to antibiotics and antifungals, but the advantage is that with prophylaxis in place, these tests are often positive when haemoculture is negative. The T2Candida test can detect Candida albicans, Candida tropicalis, Candida glabrata, Candida krusei and Candida parapsilosis, which are the more common causative agents of mycotic bloodstream infections.
