Hematopoietic reconstitution after stem cell transplantation requires excessive replicative activity because of the limited number of stem cells that are used for transplantation. Telomere shortening has been detected in hematopoietic cells after bone marrow transplantation. This has been thought to result from excessive replication of the stem cells, with putative concomitant reduction of thei...

BACKGROUND The possibility that allogeneic hematopoietic stem cell transplantation performed across the ABO blood group-barrier is associated with an increase of graft-versus-host disease, in particular endothelial damage, has not been elucidated so far. For this reason, we investigated the level of endothelial cell chimerism after allogeneic hematopoietic stem cell transplantation in order to ...

Background: There is a worldwide effort to present novel approaches for the development of tolerance-induction treatments in regenerative medicine, after years of investigation in clinical transplantation. Particularly, novel approaches are based on controlling the immune response, including the application of biomaterials or imitation of antigen-specific peripheral tolerance in either solid-or...

The frequency and distribution of CD34+ cells in the bone marrow (BM) of patients with idiopathic myelofibrosis (IM) were determined using an immunohistochemical technique. The percentage and absolute number of circulating CD34+ cells were enumerated. Patients with IM exhibited a continuum of number of BM CD34+ cells ranging from 1 to 85 per 5 mm(2). The frequency of BM CD34+ cells was inversel...

The first allogeneic identical sibling donor hematopoietic stem cell transplantation at the Institute for Mother and Child Health Care of Serbia ?Dr. Vukan Cupic? (Institute) was performed in seventies last century. Almost twenty years later, transplant from haploidentical an infant suffering severe combined immunodeficiency. After several efforts, bone marrow unit opened April 1997 Institute. ...

Hematopoietic stem cell transplantation is the curative option for patients with myelodysplastic syndrome; however, it requires a long post-transplantation follow-up. A 53-year-old woman with a diagnosis of myelodysplastic syndrome underwent related donor allogeneic hematopoietic stem cell transplantation in July 2006. Three months after transplantation, a comparative short tandem repeat analys...

A 60-year-old man presented with cough, sputum, and dyspnea. He had a history of acute myeloid leukemia and hematopoietic stem cell transplantation with chronic renal failure. Chest CT scans showed miliary nodules and patchy consolidations. Histological examination revealed numerous fibrin balls within the alveoli and thickening of the alveolar septum, both of which are typical pathological fea...

Thiamine is a water-soluble vitamin. Thiamine deficiency can present as a central nervous system disorder known as Wernicke's encephalopathy, which classically manifests as confusion, ataxia, and ophthalmoplegia. Wernicke's encephalopathy has rarely been reported following hematopoietic stem cell transplantation. Herein, we report Wernicke's encephalopathy in a patient with acute myeloid leukem...

Autologous hematopoietic stem cell transplantation has proved to be an effective treatment for certain hematologic malignancies. However, relapse rates are high during the first year after transplantation. These relapses are attributed to the failure of high-dose chemotherapy to eradicate minimal residual malignant disease. In allogeneic hematopoietic stem cell transplantation, the higher antit...
