ABSTRACT: Invasive candidiasis (IC) is a leading cause of morbidity and mortality among nonneutropenic ICU patients and these life-threatening nosocomial infections require early diagnosis and prompt treatment. However, none of the predictive tools are sufficiently accurate to identify high-risk patients and the potential interest of IC prophylactic, empirical and preemptive treatment in the nonneutropenic ICU population has not yet been demonstrated. In the case of nosocomial severe sepsis after necrotizing pancreatitis or upper digestive anastomotic leakage, early probabilistic antifungals are probably indicated. In the remaining ICU surgical and medical patients, prophylactic and empirical strategies are highly debated because they may promote antifungal selective pressure through an overuse of these molecules. In this context, non-culture-based methods such as mannan or β-D glucan or polymerase chain reaction tests are promising. However, none of these tests used alone in ICU patients is sufficiently accurate to avoid overuse of empirical/preemptive treatment. The interest of strategies associating predictive clinical scores and non-culture-based methods still needs to be demonstrated by well-conducted randomized, controlled trials. While awaiting these studies, we consider that probabilist treatment should be stopped earlier if IC is not proven.
