Invasive Fungal Infections While on Voriconazole, Liposomal Amphotericin B, or Micafungin for Antifungal Prophylaxis in Pediatric Stem Cell Transplant Patients.

Abstract

This study aimed to report the incidence of invasive fungal infections (IFIs) in pediatric hematopoietic stem cell transplant (HSCT) patients who received voriconazole, liposomal amphotericin B (L-AMB), or micafungin for primary antifungal prophylaxis (PAP). Using data retrospectively collected from institution's electronic records, this study analyzed the incidence of IFIs in pediatric HSCT patients between November 2012 and November 2016. A total of 103 patients were screened. Of the 84 patients who met inclusion criteria, 76.2%, 29.8%, and 19% patients received voriconazole, L-AMB, and micafungin, respectively. The incidence of overall IFIs was 2.08 per 1000 prophylaxis days. There were 2 mold infections identified in 2 patients. Among 3 antifungal agents, the rates of IFIs were 2.67 per 1000 prophylaxis days in L-AMB group, 2.08 per 1000 prophylaxis days in micafungin group, and 1.17 per 1000 prophylaxis days in voriconazole group. Patients who received L-AMB or micafungin had higher rates of IFIs than those who received voriconazole for PAP.
