The purpose

Allogeneic blood and marrow transplantation remains the only viable cure for children who suffer from many serious non-malignant hematological diseases. Transplantation, however, carries a high risk of fatal complications. Much of the risk stems from the use of high dose radiation and chemotherapy for conditioning, the treatment administered just prior to transplant that eliminates the patients' marrow and immune system, effectively preventing rejection of the donors' cells. Attempts to make blood and marrow transplantation safer for children with non-malignant diseases by using lower doses of radiation and chemotherapy have largely failed because of a high rate of graft rejection. In many such cases, it is likely that the graft is rejected because the recipient is sensitized to proteins on donor cells, including bone marrow cells, by blood transfusions. The formation of memory immune cells is a hallmark of sensitization, and these memory cells are relatively insensitive to chemotherapy and radiation. Alefacept, a drug used to treat psoriasis, on the other hand, selectively depletes these cells. The investigators are conducting a pilot study to begin to determine whether incorporating alefacept into a low dose conditioning regimen can effectively mitigate sensitization and, thereby, prevent rejection of allogeneic blood and marrow transplants for multiply transfused children with non-malignant hematological diseases.
