Successful Allogeneic Hematopoietic Stem Cell Transplantation for a Patient with Very Severe Aplastic Anemia During Active Invasive Fungal Infection / 임상소아혈액종양

ABSTRACT

Allogeneic hematopoietic stem cell transplantation (HSCT) may not be considered feasible in a patient with active fungal infection due to transplant-related mortality. We report a case of HSCT performed on a 6-month-old girl, who was diagnosed with very severe aplastic anemia (vSAA) at the age of 2 months, during active invasive pulmonary aspergillosis (IPA). Despite receiving continuous antifungal treatment and multiple granulocyte infusions, her IPA was aggravated. She underwent allogeneic HSCT from a matched sibling donor using conditioning regimen of fludarabine, reduced dose of cyclophosphamide, and anti-thymocyte globulin (ATG) during IPA. After neutrophil engraftment, fever subsided and IPA improved. She was continued on voriconazole for 7 months after HSCT. She is alive with normal hematopoiesis 4 years post-transplant. Our report suggests that allogeneic HSCT using conditioning regimen of fludarabine, reduced dose of cyclophosphamide, and ATG can be a feasible option for the patients with vSAA even during active fungal infection.
