- W2982186924 abstract "Abstract Background Invasive fungal infections (IFI) continue to affect the immunocompromised patient population. Many of these patients require antifungal prophylaxis. Voriconazole is an azole antifungal that has been utilized for preventing IFIs but does not have an approved indication for prophylaxis. Methods Adult patients admitted to Duke University Hospital from January 1, 2005 to December 31, 2015 who had received at least 2 days of systemic voriconazole as primary prophylaxis were included in this retrospective medical records review. Demographics, underlying comorbidities, adverse events, drug interactions, voriconazole blood concentrations, and microbiological data were assessed. Results Our review identified 403 patients receiving voriconazole for primary prophylaxis. 220 (55.6%) were male, 303 (75.2%) were Caucasian, and the mean age was 46.0 ± 15.7 years. 233 (57.8%) had leukemia, and 63 (15.6%) had lymphoma. 301 (74.7%) underwent hematopoietic transplant (BMT), and 45 (11.2%) had a solid-organ transplant. 176 (43.7%) patients received chemotherapy and 261 (64.8%) received immunosuppressive drugs. The mean voriconazole total daily maintenance dose was 416.1 ± 65.9 mg (5.5 ± 1.6 mg/kg/day). Patients received inpatient voriconazole for a mean of 19.5 ± 16.5 days. 371 (92.1%) patients received a concomitant interacting drug. Only 140 (43.7%) patients had therapeutic drug monitoring. The mean first voriconazole serum concentration was 1.8 ± 1.7 mg/L. 87 (21.6%) patients discontinued voriconazole prematurely; 41 (10.2% overall) of these patients had an adverse event requiring discontinuation. 5 had breakthrough fungal infections with microbiological data identifying a fungal species, which included Rhizopus spp. among others. Conclusion Voriconazole is frequently used for primary prophylaxis of IFIs and most commonly in BMT. It appears to be relatively well tolerated with some adverse side-effects (~10%) despite many potential drug–drug interactions and provides appropriate fungal coverage for many immunosuppressed patients. However, few patients had breakthrough fungal infections while receiving voriconazole. In a real-world setting, voriconazole can provide antifungal prevention in certain high-risk patients.
