Bone marrow transplantation (BMT) has become an accepted form of therapy for the treatment of a broad range of haematological, immunological, and inherited metabolic diseases. ~-4 In many cases it offers the opportunity for cure in previously incurable disease states. Examples include refractory leukaemias, aplastic anaemia, primary immunodeficiency syndromes, several inborn errors of metabolis...

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...

Graft-versus-host disease (GVHD) and infections are two major complications of allogeneic bone marrow transplantation (BMT). In the course of GVHD, one of the pathways that activated cytotoxic T cells use to execute their killing mechanisms is the Fas/Fas ligand pathway. This killing mechanism might be accompanied by the release of soluble Fas (sFas) in the circulation. To examine the associati...

Autoimmune Diseases (ADs) are diseases in which the immune system mistakenly attacks and destroys selfmolecules due to a disruption of immunologic tolerance to auto-reactive immune cells. The goals of treatments for ADs are to 1) reduce symptoms, 2) control the autoimmune process and 3) maintain the body’s ability to fight disease. Allogenic Hematopoietic Stem Cell (HSC) transplantation has bee...

Shwachman-Diamond syndrome (SDS) is a rare genetic disorder of unknown pathogenesis involving exocrine pancreatic insufficiency and hematological and skeletal abnormalities. About 25% of patients develop hematopoietic malignancies. We report on a case of acute myeloid leukemia (M2) in a 21-year-old woman affected by SDS. She was treated with conventional chemotherapy (idarubicin plus cytarabine...

Allogeneic bone marrow transplantation (BMT) has been associated with a graft-vs.-leukemia (GVL) reactivity. Since T cell depletion of the bone marrow graft has decreased the risk of graft-vs.-host disease (GVHD), but has been associated with higher rates of leukemia relapse, GVL reactivity is probably caused by donor-derived T lymphocytes. Previously, we demonstrated that minor histocompatibil...

MPS VII mice are deficient in beta-glucuronidase and share many clinical, biochemical, and pathologic characteristics with human mucopolysaccharidosis type VII (MPS VII). We have shown that syngeneic bone marrow transplantation (BMT) prolongs survival and reduces lysosomal storage in many organs of the MPS VII mouse. In this report, we quantify the hearing loss and determine the impact of synge...

We prospectively assessed the frequency of pulmonary complications and the natural course of lung function after bone marrow transplantation (BMT), as well as the effect of several risk factors in a homogeneous group of 39 children who underwent allogeneic or autologous BMT for haematological malignancies between 1992 and 1995. Four patients developed pneumonia within the first 3 months and thr...

T cells from allogeneic bone marrow grafts are responsible for a graft versus leukemia effect. Use of recombinant Interleukin-2 (rIL-2) after autologous bone marrow transplantation (BMT) may enhance immune function and hopefully reproduce the allogeneic reaction. We report here the hematologic and immunologic changes observed in the first 10 patients of a phase 1 trial studying the infusion of ...

Intra bone marrow-bone marrow transplantation (IBM- BMT) + thymus transplantation (TT) has been shown to reduce the incidence of graft versus host disease (GVHD) and restore donor-derived T cell function. In addition, an increase in insulin sensitivity occurred in db/db mice after IBM-BMT+TT treatment. Heme oxygenase (HO)-1 is a stress inducible enzyme which exert antioxidant, antiapoptotic, an...
