- Some sickle cell disease or beta-thalassemia can be cured with transplant. Researchers want to test a variation of transplant that uses low dose radiation and a combination of immunosuppressive drugs. They want to know if it helps a body to better accept donor stem cells.
Objectives:
- To see if low dose radiation (300 rads), oral cyclophosphamide, pentostatin, and sirolimus help a body to better accept donor stem cells.
Eligibility:
- People 4 and older with beta-thalassemia or sickle cell disease that can be cured with transplant, and their donors.
Design:
- Participants and donors will be screened with medical history, physical exam, blood test, tissue and blood typing, and bone marrow sampling. They will visit a social worker.
- Donors:
- may receive an intravenous (IV) tube in their groin vein.
- will receive a drug injection daily for 5 or 6 days to move the blood stem cells from the bone marrow into general blood circulation.
- will undergo apheresis: an IV is put into a vein in each arm. Blood is taken from one arm, a machine removes the white blood cells that contain blood stem cells, and the rest is returned through the other arm.
- Participants:
- may undergo red cell exchange procedure.
- will remain in the hospital for about 30 days.
- will receive a large IV line that can stay in their body from transplant through recovery.
- will receive a dose of radiation, and transplant related drugs by mouth or IV.
- will receive blood stem cells over 8 hours by IV.
- will take neuropsychological tests and may complete questionnaires throughout the transplant process.
- must stay near NIH for 4 months. They will visit the outpatient clinic weekly.
