Secondary Antifungal Prophylaxis in Pediatric Hematopoietic Stem Cell Transplants

Invasive fungal infections (IFIs) constitute a leading cause of morbidity and infection-related mortality among hematopoietic stem cell transplant (HSCT) recipients. With the use of secondary prophylaxis, a history of IFI is not an absolute contraindication to allo-HSCT. However, still, IFI recurrence remains a risk factor for transplant-related mortality. In this study, of the 105 children undergoing HSCT between April 2010 and February 2013, 10 patients who had IFI history before transplantation and had undergone allo-HSCT were evaluated retrospectively to investigate results of secondary prophylaxis. In conclusion, our study shows that amphotericin B and caspofungin was successful as secondary antifungal prophylaxis agents with no relapse of IFI. In addition, after engraftment, secondary prophylaxis was continued with voriconazole orally in 4 patients that yielded good results.
