BACKGROUND Current criteria for the selection of unrelated donors for hematopoietic cell transplantation (HCT) include matching for the alleles of each human leukocyte antigen (HLA) locus within the major histocompatibility complex (MHC). Graft-versus-host disease (GVHD), however, remains a significant and potentially life-threatening complication even after HLA-identical unrelated HCT. The MHC...
Allogeneic stem cell transplantation is a treatment option for malignant and non-malignant disorders in children. For children with no HLA-matched sibling or related stem cell donors, there is the option of unrelated cord blood donors. At the University of Malaya Medical Centre (UMMC) in Kuala Lumpur, the first unrelated cord blood transplantation (CBT) was performed in October 1997. All unrela...
Medical advances have made bone marrow transplantation the treatment of choice for certain hematologic diseases. For those patients eligible for a marrow transplant only about 30 percent find an HLA-compatible match within their families. Studies indicate that unrelated volunteers are willing to donate their marrow. The National Marrow Donor Program was formed in 1986 as a result of a federal c...
Forty patients with advanced hematologic malignancies or severe aplastic anemia received marrow grafts from partially mismatched, unrelated marrow donors. All patients were administered conventional prophylaxis for acute graft-v-host disease (GVHD) consisting of methotrexate and low-dose glucocorticoids. All but two patients who survived at least 30 days showed durable engraftment. Six patients...
BACKGROUND Randomized trials have shown that the transplantation of filgrastim-mobilized peripheral-blood stem cells from HLA-identical siblings accelerates engraftment but increases the risks of acute and chronic graft-versus-host disease (GVHD), as compared with the transplantation of bone marrow. Some studies have also shown that peripheral-blood stem cells are associated with a decreased ra...
BACKGROUND Renal transplantation is the ideal method for management of end-stage renal disease. The use of living donors for renal transplantation was critical for early development in the field and preceded the use of cadaveric donors. Most donors are related genetically to the recipients, like a parent, a child, or a sibling of the recipient, but there are an increasing percentage of cases wh...
To reduce the morbidity and mortality associated with unrelated donor bone marrow (BM) transplantation and potentially extend the pool of suitable donors, cryopreserved unrelated donor umbilical cord blood was considered as an alternate source of hematopoietic stem cells for transplantation. Patients with leukemia, BM failure syndrome, or inborn error of metabolism were eligible for a phase I c...
