Successful related umbilical cord blood transplantation for graft failure following T cell-depleted non-identical bone marrow transplantation in a child with major histocompatibility complex class II deficiency.
Major histocompatibility complex (MHC) class II deficiency is a rare form of primary combined immunodeficiency that can only be corrected by stem cell transplantation. We report a 4(1/2)-year-old girl with MHC class II deficiency who underwent a related CBT due to graft failure following T cell-depleted non-identical BMT. The patient is alive and well 2 years after the second transplant. A sustained hematopoietic engraftment and a progressive immune recovery have been detected. We conclude that cord blood may be an effective source of hematopoietic stem cells for patients with immuno- deficiency disorders including diseases with a high rate of graft failure.
