We have studied the outcome of 211 consecutive unrelated donor (URD) bone marrow transplants (BMT) performed at the University of Minnesota (Minneapolis, MN) between May 1985 and December 1992. Ninety patients (43%) received marrow matched serologically at HLA A, B, and DR loci; 86 (41%) received marrow with a major and 32 (15%) marrow with a minor serologic mismatch at the HLA A or B locus. Mu...

In an animal bone marrow transplant (BMT) model that mimics the human clinical condition, we evaluated the effectiveness of monoclonal antibody (MoAb) therapy in eliminating minimal residual disease (MRD) in a leukemic host. Leukemic rats were prepared with marrow ablative but noncurative doses of busulfan (BU) and cyclophosphamide (CY). Two days after syngeneic BMT, rats were treated with MoAb...

Representatives of 17 bone marrow transplant (BMT) teams met to discuss the problems of infection after BMT. With experience of more than 2200 transplanted patients over the past 10 yr, the changes in the patterns of infection were surprisingly similar. Deaths due purely to bacterial infection have greatly diminished and the major early problems today result from fungi and cytomegalovirus. The ...

The number of allogeneic and autologous bone marrow transplants continues to grow worldwide. Bone marrow transplantation (BMT) has become standard therapy for many patients with leukemia, lymphoma, multiple myeloma and testicular cancer. Encouraging results of autologous BMT in treating patients with poor-risk breast cancer have led to this approach being tested in nationwide randomized trials....

We examined the potential of bone marrow transplantation (BMT) to rescue dopaminergic neurons in a mouse model of Parkinson's disease (PD). A BMT from mice transgenic for green fluorescent protein (GFP(+)) given either before or after administration of the neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) led to the accumulation of transplanted adult GFP(+) bone-marrow-derived cell...

Bone marrow transplantation (BMT) can cure patients with high-risk or recurrent acute lymphoblastic leukemia (ALL). Those lacking a related donor can receive either autologous or histocompatible unrelated donor (URD) marrow. Autotransplantation may result in higher risk of relapse, whereas URD allografts, although associated with serious posttransplant toxicities, may reduce relapse risk. Six y...

The kinetics of T and B cell immune recovery after bone marrow transplantation (BMT) is affected by many pre- and post-transplant factors. Because of the profoundly depleted baseline T and B cell immunity in recombination activating gene 2 (RAG-2)-deficient severe combined immunodeficiency (SCID) patients, some of these factors are eliminated, and the immune recovery after BMT can then be clear...

Loss of bone mass is usually detected after bone marrow transplantation (BMT) during the early post-transplant period. However, little is known about the long-term effects of BMT on bone metabolism. We have prospectively investigated 11 patients undergoing BMT. Bone mineral density (BMD) was measured before BMT, and 1, 2, and 3 yr after BMT. Serum markers of bone turnover were serially measured...

Forty-eight patients treated by allogeneic bone marrow transplantation (BMT) for Philadelphia (Ph) chromosome-positive chronic myeloid leukemia in chronic phase had serial cytogenetic studies of marrow performed at intervals after transplant. Twenty patients received marrow cells from donors of opposite sex. Ph+ marrow metaphases were identified in 24 of 48 (50%) of patients after BMT; they wer...

It is well established that Down's syndrome exhibits a predisposition to development of leukemia, however, association between aplastic anemia and Down's syndrome is exceptional. Herein, we describe a case of aplastic anemia occurring in Down's syndrome following post-transplant lymphoproliferative disorder (PTLD) after bone marrow transplantation (BMT). A 27-year-old Japanese male with Down's ...
