Abstract: | Invasive fungal infections (IFIs) pose the most serious infectious risk to patients with hematologic malignancies and in those
undergoing hematopoietic stem cell transplantation (HSCT). Invasive candidiasis has an incidence of 8–18% and a mortality
of 30–40% in various reports. Invasive aspergillosis has an incidence of 4–15% and an even higher mortality of 60–85% cited
in the published literature. IFIs have remained difficult to diagnose in a timely way in neutropenic and immunocompromised
patients. A timely diagnosis is essential in promptly initiating antifungal therapy in order to optimize clinical outcomes.
Thus, antifungal prophylaxis has an enormous appeal to minimize the threat from IFIs. In this article, the epidemiology and
risk factors for IFIs as well as evidence from antifungal prophylaxis clinical trials in certain patient groups with hematologic
malignancies are reviewed. Antifungal prophylaxis has been shown to be effective in certain settings. However, concerns about
shifts in fungal epidemiology, emergence of resistance, drug toxicities, and drug interactions must be considered in deciding
how and in whom to use antifungal prophylaxis. |
