Abstract
We report a 4-year-old girl who presented with acute onset of hemophagocytic syndrome (HPS) after induction therapy and HPS relapsed immediately after reduced-intensity cord blood transplantation (RI-CBT) for relapse of acute lymphoblastic leukemia. The patient underwent CBT from 2 locus-mismatched donor, after reduced-intensity conditioning therapy consisting of fludarabine, melphalan, and total body irradiation 4Gy. Prednisolone and cyclosporine were administered for prophylaxis against graft-versus-host disease. Bone marrow examination on day 20 revealed activated macrophages displaying hemophagocytosis. The origin of macrophages was 2nd donor derived. After administration of steroids, intravenous immunoglobulin and VP-16, the patient exhibited complete chimerism and remained in complete remission for over one year.
