The role of the ABO blood group system in determining the outcome of bone marrow transplantation was investigated in 53 patients with aplastic anemia and acute leukemia grafted from HLA-identical siblings. There was no correlation between ABO compatibility and marrow engraftment, graft rejection, or graft-versus-host disease. In 5 recipients with antibodies prior to transplantation to antigens ...

BACKGROUND CD40 ligand (CD40L) deficiency is a rare X linked immunodeficiency disorder leading to recurrent bacterial infection, with cryptosporidial enteritis and subsequent hepatic cirrhosis. Bone marrow transplantation offers the only cure. OBJECTIVE To analyse retrospectively the outcome of bone marrow transplantation for this condition in one centre. DESIGN A retrospective case note an...

OBJECTIVES Bone loss is a complication for patients with liver diseases and after transplantation, which results in increased fracture risk. The aim of this study was to determine the incidence of osteoporotic vertebral fractures following liver transplantation. METHODS We performed a prospective study of patients who were awaiting liver transplantation. Patients were seen at baseline (visit ...

BACKGROUND Bone fragility is common post solid organ transplantation but little is known about bone pathology on a tissue level. Abnormal osteocytic protein expression has been linked to compromised bone health in chronic kidney disease (CKD) and immunosuppressant medications may impact osteocyte function. METHODS Transiliac bone biopsies were obtained from 22 pediatric solid organ allograft ...

Bone marrow fibrosis is a hallmark of primary and post ET/PV myelofibrosis. To investigated the impact of replacement of the hematopoietic system in myelofibrosis patients by allogeneic stem cell transplantation on bone marrow fibrosis, we studied bone marrow fibrosis on bone marrow samples from 24 patients with myelofibrosis before and after dose-reduced conditioning followed by allogeneic ste...

BACKGROUND/AIMS Sclerostin is secreted by osteocytes. As a circulating inhibitor of the Wnt-signaling pathway it inhibits bone formation and contributes to the development of osteoporosis. Sclerostin levels are elevated in patients with chronic kidney disease and end-stage renal disease. Since data for patients after kidney transplantation are scarce, we have prospectively measured sclerostin l...

Bone marrow transplantation (BMT) has evolved from an experimental undertaking to an established therapeutic strategy for hematological neoplasias, severe aplastic anemia, congenital immunological and metabolic disorders and some solid tumors. This report summarizes the main indications for autologous and allogenic transplants, the prerequisites and potential techniques, early and late complica...

I N recent years a number of methods have been developed to induce donor-specific transplantation tolerance in adult recipients using bone marrow transplantation. 1-4 One approach. using a mixture of syngeneic and allogeneic bone marrow to prepare allogeneic chimeras (A + B A) has been demonstrated to be effective in achieving longterm donor-specific transplantation tolerance to alloantigens in...
