Successful Engraftment and Durable Graft-versus-host Disease Control with Haploidentical Peripheral Blood and a...

Primary graft failure occurred after cord blood transplantation for a patient with acute lymphoblastic leukemia. The second transplantation was performed using haploidentical peripheral blood. The conditioning regimen consisted of fludarabine (day -1; 30 mg/m(2)), cyclophosphamide (day -1; 2,000 mg/m(2)), and total body irradiation (day -1; 2 Gy). The immunosuppressants contained tacrolimus, prednisolone, and rabbit anti-thymocyte globulin (day -3 to -2; total dose: 3.75 mg/kg). The engraftment was confirmed on day 9. Both acute and chronic graft-versus-host disease were controllable. The present regimen appears to be suitable for immediate management, fast engraftment, and the durable control of complications.
