Efficacy and safety of voriconazole as invasive fungal infection prophylaxis in patients with acute myeloid leukemia.

Invasive fungal infections (IFIs) are commonly observed in patients, who are at high risk of severe infections during the neutropenic phase. The aim of this retrospective single-center study was to evaluate the efficacy and safety of voriconazole as a fungal prophylaxis after induction chemotherapy for acute myeloid leukemia (AML) in adult patients. Six proven/probable IFIs were diagnosed in 213 patients with AML (median age 61 years, range 18-85), who received a total of 377 induction chemotherapies. This yielded an incidence rate of 1.6% based on all induction cycles administered. Voriconazole prophylaxis was administered as intended in 317 out of 377 (84%) induction cycles until the end of neutropenia with a median duration of 20 days (range: 2-101 days). In conclusion, voriconazole demonstrates efficacy and safety as a first-line IFI prophylaxis comparable to published data on posaconazole, which is the standard fungal prophylaxis recommendation for AML patients in international guidelines today.
