OBJECTIVE Transplantation of isolated hepatocytes in animal models has been shown to correct inborn errors of metabolism. Based on these studies and our experience with hepatocyte transplantation in a child with Crigler-Najjar syndrome, isolated hepatocyte transplantation was performed to attempt metabolic reconstitution in a male infant with severe(More)
Long-term survival and improved neuropsychological function have occurred in selected children with Hurler syndrome (MPS I H) after successful engraftment with genotypically matched sibling bone marrow transplantation (BMT). However, because few children have HLA-identical siblings, the feasibility of unrelated donor (URD) BMT as a vehicle for adoptive(More)
PURPOSE To determine the toxicity and response rate in children treated with dexamethasone, etoposide, cisplatin, high-dose cytarabine, and L-asparaginase (DECAL) for recurrent non-Hodgkin's lymphoma (NHL) and Hodgkin's disease (HD). PATIENTS AND METHODS Ninety-seven children with recurrent NHL (n = 68) or HD (n = 29) were enrolled. Treatment consisted of(More)
Forty-one patients were studied at set times after allogeneic blood stem cell transplantation (alloBSCT) for recovery of lymphocyte numbers and function. Cells were mobilized with G-CSF from HLA-matched related donors and cryopreserved. Graft-versus-host disease (GVHD) prophylaxis consisted of cyclosporine and methotrexate; G-CSF was administered(More)
A five-month-old girl with autosomal-recessive osteopetrosis received a bone-marrow transplant from her five-year-old HLA-MLC-identical brother after preparation with cyclophosphamide and modified total-body irradiation. Engraftment was documented by chromosomal analysis. Anemia, thrombocytopenia, and leukoerythroblastosis corrected within 12 weeks of(More)
This report describes an allogeneic peripheral blood stem cell transplant in a patient who had received marrow ablative therapy. The patient was an 18-year-old white male with acute lymphocytic leukemia in third remission for whom an allogeneic bone marrow transplant was recommended. His HLA-identical sibling preferred to donate peripheral blood stem cells(More)
PURPOSE The optimal dose of granulocyte colony-stimulating factor (G-CSF) for mobilization of allogeneic-blood stem cells (AlloBSC) has yet to be determined. As part of a prospective trial, 41 related human leukocyte antigen (HLA)-matched donors had blood cells mobilized with G-CSF at 5 micrograms/kg/d by subcutaneous administration. The purpose of this(More)
We report nine children with relapsed (n = 8) or high-risk (n = 1) peripheral T-cell lymphoma (PTCL) who underwent autologous (n = 6) or allogeneic (n = 3) bone marrow transplantation (BMT). These children received transplants as part of a prospective phase I/II study of thioTEPA (TT) and total body irradiation (TBI) with escalating doses of VP-16. The(More)
To understand the susceptibility of allogeneic bone marrow transplant recipients to pneumococcal infection, we measured the level of type-specific antibodies to pneumococcal capsular polysaccharide in serum from ten marrow recipients. Seven recipients received marrow from matched sibling donors who had recently been vaccinated with polyvalent pneumococcal(More)
