The subpopulation of regulatory T cells (Treg) was shown to play a key role in alloreactive responses. In allogeneic hematopoietic stem cell transplantation, several groups tested whether Treg content in transplants correlates with graft-versus-host disease (GVHD) with controversial results. In a retrospective study of 49 consecutive HLA-matched sibling transplantations, we studied the relation...

background: during the resent years there has been interest in using bone marrow stem cells to treat liver cirrhosis. however, there is a potential concern for malignant transformation after stem cell therapy. the aim of this study was to evaluate the development of hepatocellular carcinoma (hcc) after autologous bone marrow stem cell transplantation for liver cirrhosis. methods: all the patien...

We report a 10-year-old boy with a severe form of immunodeficiency with hyper-IgM who underwent successful bone marrow transplantation with his HLA-matched sister as donor. Busulfan (20 mg/kg) and cyclophosphamide (200 mg/kg) were used as conditioning. The post-transplant course was uneventful. He is alive 25 months later with full hematological and immunological reconstitution. BORDIGONI, P, e...

Transplantation of normal bone marrow to mice with the Chediak-Higashi syndrome (CHS) resulted in normal granulopoiesis and a reversal of their increased susceptibility to challenge with intravenous Candida albicans. These findings suggest that (1) the leukocyte defect in CHS can be reversed by marrow transplantation and (2) the mechanism for increased susceptibility to infection in these anima...

Bone disease remains a major cause of morbidity after renal transplantation. Post-transplant osseous complications include osteoporosis and osteonecrosis, both historically associated with glucocorticoids, and a newer syndrome of bone pain associated with calcineurin inhibitors. Calcineurin inhibitor-induced pain syndrome (CIPS) is a reversible etiology of lower extremity bone pain and bone mar...

Neurological complications of malignant infantile osteopetrosis are well recognised; successful bone marrow transplantation, when performed early in life, can prevent or halt some of them. In a subgroup of infants osteopetrosis is associated with primary retinal degeneration and/or generalised neurodegeneration. Bone marrow transplantation, in spite of being successful in correcting the osseous...

Monosomy 7 arises as a recurrent chromosome aberration in donor cell leukemia after hematopoietic stem cell transplantation. We report a new case of donor cell leukemia with monosomy 7 following HLA-identical allogenic bone marrow transplantation for severe aplastic anemia (SAA). The male patient received a bone marrow graft from his sister, and monosomy 7 was detected only in the XX donor cell...

Background: Bone marrow and stem cell transplantation have become conventional therapy, with the potential to cure a variety of hematologic malignancies immunologic diseases. Severe infection is still potentially fatal complication following transplantation, contributes significantly morbidity, may demand ICU admission. Objectives: The study aims summarize current evidence on prevalence, risk f...
