Successful hematopoietic stem cell transplantation for aplastic anemia following living-related liver transplantation

Abstract

A 1-year-old boy received a living-related liver transplantation (LRLT) from his HLA-haploidentical father to treat acute liver failure following non-A, non-B, non-C hepatitis. He subsequently developed pancytopenia and was diagnosed with aplastic anemia (AA). He was platelet transfusion dependent and developed two episodes of life-threatening intracranial hemorrhage despite immuno-suppressive therapy consisting of cyclosporin A, antithymocyte globulin, and anabolic steroids. He received combined hematopoietic stem cell transplantation (hSCT) with cord blood and bone marrow from an HLA-matched sibling. Conditioning consisted of cyclophosphamide (CY) 200 mg/kg and 7 Gy total lymphoid irradiation (TLI). Marrow engraftment was prompt and there was no significant graft-versus-host disease (GVHD).
