Isolated granulocytic sarcoma (GS) has rarely been reported in a patient who underwent allogeneic bone marrow transplantation (BMT) for chronic myelogenous leukemia (CML). We report here a patient who developed an isolated GS after achieving hematologic and cytogenetic remission by donor lymphocyte infusion for the relapse of CML following BMT. The size of GS was slightly decreased after local ...

Although the graft-versus-leukemia effect of allogeneic bone marrow transplantation (BMT) is of paramount importance in the maintenance of disease remission, the role played by the autologous T-cell response in antitumor immune surveillance is less defined. We evaluated the emergence of antileukemia cytotoxic T-lymphocyte precursors (CTLp's) and the correlation of this phenomenon with maintenan...

Male BXSB mice spontaneously develop autoimmune disease with features similar to systemic lupus erythematosus. To determine whether this autoimmune disease can be treated as well as prevented by bone-marrow transplantation (BMT) and, at the same time, whether the immunity functions of lethally irradiated recipients can be reconstituted fully, male BXSB mice were engrafted with mixed T cell-depl...

The interaction of TNF-alpha with TNF receptor 1 (TNFR1) activates several signal transduction pathways that lead to apoptosis or NF-kappa B-dependent inflammation and immunity. We hypothesized that host TNFR1 expression contributes to noninfectious lung injury and inflammation commonly observed after bone marrow transplantation (BMT), termed idiopathic pneumonia syndrome (IPS). C57BL/6 TNFR1-s...

Fifteen patients with acute lymphocytic leukemia (ALL) in second or subsequent remission received intensive therapy with cyclophosphamide and single dose. rapid rate (26 cGy/min) total body irradiation (TBI) followed by bone marrow transplantation (BMT) from a histocompatible sibling match. Outcome was compared to that of 23 conventionally treated control patients in second ALL remission who pr...

We have recently shown that early administration of interleukin 18 (IL-18) after bone marrow transplantation (BMT) attenuates acute graft-versus-host disease (GVHD) in a lethally irradiated parent into F1 (B6-->B6D2F1) BMT model. In this study, we investigated whether IL-18 can maintain graft-versus-leukemia (GVL) effect in this context. B6D2F1 mice received transplants of T-cell-depleted (TCD)...

The pathogenic effect of cytomegalovirus (CMV) infection on the hematopoietic recovery after bone marrow transplantation (BMT) was retrospectively studied in 87 recipients of (nonpurged) autologous BMT and in 56 recipients of allogeneic BMT from HLA-identical siblings. Indications for autologous BMT were lymphomas or acute leukemias and for allogeneic BMT various malignancies or aplastic anemia...

Despite improvements in human leukocyte antigen matching and pharmacologic prophylaxis, acute graft-versus-host disease (GVHD) is often a fatal complication following hematopoietic stem cell transplant (HSCT). Older HSCT recipients experience significantly increased morbidity and mortality compared to young recipients. Prophylaxis with syngeneic regulatory dendritic cells (DCreg) in young bone ...

BACKGROUND AND OBJECTIVE After allogeneic bone marrow transplantation (BMT) it is important to be able to distinguish between the host and donor origin of cells in order to monitor the engraftment process. However, identifying whether the hematopoietic stem cells are of donor or recipient origin may be a difficult task. DNA studies using Southern blotting techniques or the amplification by PCR ...

Autologous bone marrow transplantation (BMT) was utilized as therapy for 23 patients with acute lymphoblastic leukemia (All) in second or greater remission. Bone marrow was treated in vitro with a combination of monoclonal antibodies, consisting of BA-i . BA-2. BA-3, and baby rabbit complement (BRC’). All patients were prepared for transplantation with cyclosphosphamide and fractionated total b...
