Successful Use of Granulocyte Transfusion Therapy as a Bridge to Hematopoietic Stem Cell Transplant in a Child With Aplastic Anemia and Refractory Perirectal Abscess.

This brief report describes the use of adjuvant granulocyte transfusion therapy to successfully treat refractory proctitis with perirectal abscess in a child with very severe aplastic anemia. She was not expected to have imminent neutrophil recovery, which, by current practice guidelines, is a prerequisite for the consideration of granulocyte transfusion. However, the risk of bowel perforation potentially hastened by conditioning and/or engraftment precluded curative hematopoietic stem cell transplantation, presenting a significant treatment conundrum. This case highlights an expanded clinical indication for granulocyte therapy in a uniquely vulnerable patient population.
