Bone marrow transplantation (BMT) is often followed by significant morbidity and mortality due to protracted immunodeficiency. We have hypothesized that the bone marrow-ablative regimen may delay the recovery of normal immune function following transplantation by impairing the interaction of host endothelial cells with circulating graftderived lymphocytes. This report compares the relative effe...

An eight-month-old boy with chronic granulomatous disease (CGD) received HLA identical sibling bone marrow transplantation (BMT) following busulphan and cyclophosphamide conditioning. No graft-versus-host disease was demonstrated. Five years after transplantation, mixed chimerism was 60% in peripheral blood, and 85% of his neutrophils had normal oxidative burst activity. He is now six years old...

Allogeneic bone marrow transplantation (BMT) was carried out on a 5-year-old boy with congenital hypoplastic anemia (CHA), who did not respond to corticosteroids and who was displaying signs of progressive hemosiderosis. Pretransplant preparation had to be modified because respiratory failure and cerebral edema supervened. This preparatory regimen consisted of busulfan (2 mg/kg for four days), ...

We describe data on a 7-year-old girl with congenital dyserythropoietic anemia (CDA), who also had familial Mediterranean fever (FMF). Repeated transfusions required since the age of 6 months to treat her CDA led to iron overload and a persistently high ferritin level. Her relapsing FMF made effective iron chelation therapy very difficult. Consequently, at the age of 4 years, she underwent allo...

Hemopoietic stem cells (HSCs) can be harvested from the bone marrow, peripheral blood or umbilical cord blood. HSC transplantation is used to treat hematologic and lymphoid cancers and other disorders. Some reports have indicated that Bone Marrow Transplantation (BMT) might cure these intractable diseases--including hematological disorders, autoimmune diseases and age-associated diseases. Intra...

We have used DNA sequence polymorphism analysis to document engraftment after T cell-depleted bone marrow transplantation (BMT), with a selected panel of four DNA probes. In contrast to nondepleted BMT recipients, the patients who received T cell-depleted marrow exhibited a mixed blood chimerism. This mosaicism was observed before graft failure or relapse in six patients. However, in five other...

We report five cases of cytomegalovirus infection in immunocompromised patients which were detected by either cytomegalovirus antigenemia assay or in situ hybridization. Four cases had leukemia and the other had chronic renal failure. All the three BMT recipients suffered from GvHD. Interestingly, there was an unique case of CMV disease without a history of BMT, which reminded us that CMV could...

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...

Unrelated cord blood transplantation (CBT) has now become more common, but as yet there have been only a few reports on its outcome compared with bone marrow transplantation (BMT), especially for adults. We studied the clinical outcomes of 113 adult patients with hematologic malignancies who received unrelated BM transplants (n = 45) or unrelated CB transplants (n = 68). We analyzed the hematop...

Idiopathic pneumonia syndrome (IPS) is a major complication after allogeneic bone marrow transplantation (allo-BMT) and involves the infiltration of donor leukocytes and the secretion of inflammatory cytokines. We hypothesized that leukocyte recruitment during IPS is dependent in part upon interactions between chemokine receptor 2 (CCR2) and its primary ligand monocyte chemoattractant protein-1...
