Human severe combined immunodeficiency (SCID) can be caused by defects in Janus kinase 3 (JAK3)-dependent cytokine signaling pathways. As a result, patients are at high risk of life-threatening infection. A JAK3 -/- SCID mouse model for the human disease has been used to test whether transplant with retrovirally transduced bone marrow (BM) cells (JAK3 BMT) could restore immunity to an influenza...

Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening disorder of immune regulation leading to widespread lymphocytic and hemophagocytic infiltration of vital organs. Apparent cure has only been achieved with allogeneic bone marrow transplantation (BMT). This report describes 20 consecutive patients, who underwent either matched sibling donor (n = 4) or unrelated donor (URD; n = 16) BM...

We evaluated the growth of children with acute leukemia who received a bone marrow transplant (BMT) after preparation with hyperfractionated total body irradiation (TBI). Seventy-two patients (27 female and 45 male patients) with acute lymphoblastic leukemia (ALL; n = 39) or acute myelogenous leukemia (AML; n = 33) who were l e u than 14 years of age at BMT were studied. Before BMT all had rece...

Apolipoprotein (apo)E is synthesized in atherosclerotic lesions by macrophages, however, its role in lesions is not known. Whereas apoE could exacerbate atherosclerosis by promoting macrophage uptake of cholesterol-rich lipoproteins or modulating protective inflammatory responses, it could also restrict lesion formation by facilitating cholesterol efflux out of lesions. The role of apoE was exa...

Congenital or acquired severe aplastic anaemia (SAA) is cured by bone marrow transplantation (BMT) from a histocompatible leukocyte antigen- (HLA-) identical sibling. The best conditioning regimen is cyclophosphamide (CTX) with or without antithymocyte globulin (ATG), followed by short-term methotrexate (MTX) and cyclosporine A (CsA) to prevent graft-versus-host disease (GvHD). In our pediatric...

We have investigated approaches to induce graft-versus-leukemia (GVL) effect in autologous bone marrow transplantation (ABMT) without graft-versus-host disease to improve survival and cure in leukemia. The present study shows that bone marrow transplantation (BMT) using syngeneic bone marrow activated with interleukin-2 (ABM) for 24 hours in vitro, followed by interleukin-2 (IL-2) therapy, was ...

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...

Unrelated bone marrow transplantation (BMT) is often complicated by fatal opportunistic infections. To evaluate features unique to immune reconstitution after unrelated BMT, the lymphoid phenotype, in vitro function, and life-threatening opportunistic infections after unrelated and related T-cell-depleted (TCD) BMT were analyzed longitudinally and compared. The effects of posttransplant donor l...

BACKGROUND Thoracic endovascular aortic repair (TEVAR) has been used in patients with uncomplicated type B acute aortic dissection (B-AAD) to reduce late morbidity and mortality. The outcomes of comparisons between TEVAR and best medical treatment (BMT) on patients with uncomplicated type B-AAD are inconsistent in the published reports. OBJECTIVES This study sought to further clarify the earl...

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 ...
