OBJECTIVES: I. Ascertain whether stem cell transplantation (SCT) is an effective method by which missing or dysfunctional enzymes can be replaced in patients with various inborn errors of metabolism.
II. Determine whether clinical manifestations of the specific disease may be arrested or reversed by this treatment.
|Condition or disease||Intervention/treatment|
|Thrombocytopenia Metachromatic Leukodystrophy Fanconi's Anemia Thalassemia Major Pure Red-Cell Aplasia Inborn Errors of Metabolism||Procedure: Stem Cell Transplantation|
PROTOCOL OUTLINE: Patients receive either cyclophosphamide and high dose total body irradiation (TBI) or busulfan and cyclophosphamide.
Cyclophosphamide IV is given on days -5 and -4 and TBI on days -2, -1, and 0. Busulfan is given orally every 6 hours on days -9 through -6 and cyclophosphamide IV on days -5 through -2. Patients rest on day -1.
Patients receive bone marrow infusion on day 0. For GVHD prophylaxis, patients receive methotrexate on day 1, then on days 3, 6, and 11. Cyclosporine IV begins on day -2 over 12 hours, followed by continuous infusion for 21 days. Then, oral doses of cyclosporine are given every 12 hours to patients who tolerate oral feeding. Cyclosporine is continued 6 months posttransplant, then tapered 10% per week and stopped.
Patients who receive genotypically HLA nonidentical stem cells undergo additional GVHD prophylaxis with methylprednisolone (IV or PO) or its equivalent every 12 hours on days 3 to day 100. Dose is then tapered as tolerated over 1 month.
Patients who receive cord blood stem cells receive methylprednisolone instead of methotrexate for GHVD prophylaxis. Methylprednisolone is given 3 times daily beginning on day 5 and continuing until day 17. Then, methylprednisolone is tapered 10% per week as clinically tolerated.
To accelerate engraftment, patients receive filgrastim IM daily beginning on day +1 and continuing until ANC equals 5000.
