When successful, human leukocyte antigen (HLA)-matched bone marrow transplantation with reduced-intensity conditioning is a cure for several nonmalignant hematologic disorders that require chronic transfusion, such as sickle cell disease and aplastic anemia. However, there are unusually high bone marrow transplant (BMT) rejection rates in these patients. Rejection correlates with the number of ...

The only way to overcome the need for life-long immunosuppression in a transplant recipient is to induce tolerance. Deletional tolerance can be reliably achieved with the induction of mixed chimerism through transplantation of donor bone marrow (BM). Despite the development of increasingly milder BM transplantation (BMT) animal models, BM engraftment in humans still requires considerably toxic ...

There is little information available regarding the outcome of unrelated bone marrow transplantation (BMT) for non-Hodgkin lymphoma (NHL). Therefore, we retrospectively analyzed the data of 124 patients who underwent unrelated BMT through the Japan Marrow Donor Program (JMDP) between July 1992 and August 2001. The overall survival (OS), progression-free survival (PFS), cumulative incidences of ...

Idiopathic pneumonia syndrome (IPS) refers to diffuse, non-infectious pneumonia that occurs after allogeneic bone marrow transplantation (BMT). We have developed a model of IPS using a well-characterized murine BMT system (B10.BR-->CBA) in which lung injury after BMT can be induced by minor histocompatibility (H) antigenic differences between donor and host. Lung pathology and broncho-alveolar ...

IgA nephropathy is the most common primary glomerulonephritis, but the pathogenesis of IgA nephropathy is still unclear. A 32-year-old woman was found to have IgA nephropathy and acute myeloid leukaemia. She was treated with allogenic bone marrow transplantation (BMT). After BMT, immunoflourescent staining of IgA and proteinuria disappeared. These findings suggest bone marrow cells are involved...

Increase in endothelial cell sloughing and diminished function of endothelial stem cell progenitors in diabetic subjects are well known phenomena. We hypothesized that transplantation of bone marrow stem cells (BMSCs) including mesenchymal stem cells but not limited to CD34(+) stem cells into type 2 diabetic ob mice would restore insulin sensitivity and glucose tolerance. This approach, when co...

Bone marrow transplantation (BMT) is the only curative therapy for sickle cell disease (SCD). However, the morbidity and mortality related to pretransplantation myeloablative chemotherapy often outweighs the morbidity of SCD itself, thus severely limiting the number of patients eligible for transplantation. Although nonmyeloablative transplantation is expected to reduce the risk of BMT, it will...

During the last two decades conventional therapy has improved the prognosis of thalassemia. However, despite such improvement it still remains a progressive disease with treatment-related complications such as hepatitis, liver fibrosis, and cardiac disease. Bone marrow transplantation (BMT) can prevent or delay progression of the aforementioned complications. The importance of clinical research...

Up to 60% of all children that receive to bone marrow transplantation (BMT) develop respiratory distress. It constitutes a common complication in this kind of patients, due to the increasing number of therapeutic applications of BMT and to improvement in the therapeutic approach to the problems associated with this procedure. We describe the different causes of respiratory distress after BMT in...

BACKGROUND No studies so far have examined enteric infections in patients undergoing bone marrow transplantation (BMT) in developing countries where asymptomatic carriage and colonization with enteric pathogens is frequent. METHODS A prospective study followed 65 patients who underwent BMT in South India between 1995 and 1998. Patients were screened for enteric pathogens before transplantatio...
