Study Summary

Background: Bone marrow transplantation (BMT), which involves transplanting a donor's marrow stem cells, is capable of curing some congenital anemias. BMT usually involves high-intensity treatment with chemotherapy and radiation to kill abnormal cells, which affects all systems of the body. People with anemias often have damage to other organs such as the kidneys, which can be further damaged by the chemotherapy. Only approximately 20 percent of patients have a full-matched donor, making treatment for many people with anemias unavailable. However, 90 percent of patients may have a half-matched donor, but using a half-matched donor increases the toxicity of BMT. Objectives: To determine if a research BMT with half-matched donor cells, low-intensity radiation, immunosuppressant drugs, and no chemotherapy will be effective in patients with sickle cell disease and Beta-thalassemia. To determine the effectiveness of cyclophosphamide, an immunosuppressant drug, in preventing rejection of the donor cells. Eligibility: Recipients are individuals at least 18 years of age who have been diagnosed with sickle cell disease and Beta-thalassemia, and who have a family member who is a haploidentical (i.e., half match) tissue match. Donors are healthy individuals between the ages of 2 and 80 who are found to be suitable donors. Design: Donors will undergo apheresis, which involves withdrawing blood from one arm vein, passing it through a machine that removes bone marrow stem cells, and returning the remaining blood through the vein in the other arm. Donors will receive a drug that causes the stem cells to be released into the bloodstream prior to the apheresis procedure. Recipients will undergo routine physical and laboratory examinations, including bone marrow sampling at the beginning of the study. After transplantation, physical and laboratory examinations will occur on a weekly or twice weekly basis at the outpatient clinic. Recipients will be examined every 6 months
