Candida infections in the intensive care unit: epidemiology, risk factors and therapeutic strategies.

This article reviews the epidemiology, predisposing risk factors and outcome of systemic Candida spp. infections in the intensive care unit setting. Incidence of systemic Candida infections in patients requiring intensive care has increased substantially in recent years; while diagnosis of serious Candida infection may be difficult, the clinical conditions which predispose patients to these infections are now better understood and effective antifungal therapies are becoming increasingly available. Severe fungal infections are generally associated with poor outcomes in these patients. Patients at highest risk for Candida infection may be potential candidates for early, presumptive therapy. In this article we review antifungal treatment, including the use of polyenes, azoles and echinocandines, and the role of prophylaxis.
