ABSTRACT: Invasive fungal disease (IFD) causes significant morbidity and mortality among children undergoing allo-SCT. In this prospective pilot study, we analyze voriconazole as primary antifungal prophylaxis. From October 2004 to July 2010, 56 children <18 years of age were enrolled in this study. Patients received voriconazole doses of 5 mg/kg per 12 h (n=23) or 7 mg/kg per 12 h (n=33), with a limiting dose of 200 mg/12 h, from day -1 to day +75 or later in patients with active acute GVHD. Patients were followed up for IFD for 6 months. In this series, 37 (66.1%) patients successfully completed treatment (85.7% during neutropenic period) without empirical or preemptive antifungal therapy, adverse effects or IFD. Nine (16.1%) children needed preemptive (n=2) or empirical (n=7) antifungal therapy, and one (1.8%) of them developed a fatal probable IFD during the study period. A total of 10 (17.8%) children developed adverse effects related to voriconazole prophylaxis, leading to definitive withdrawal on median day 26.5 (in 7 patients after granulocytic recovery). The most frequent adverse effect was persistent elevation of hepatic enzymes in seven (12.5%) children. There were no differences between doses of 5 and 7 mg/kg per 12 h. Our results suggest that voriconazole can be safely used as primary antifungal prophylaxis in children undergoing allo-SCT.
