Hematopoietic stem cell transplantation has been used for many years to treat various malignant and nonmalignant hematologic conditions. However, the high-dose conditioning regimen can lead to major organ dysfunction, life-threatening infection and bleeding. In the allogeneic setting, graft-versus-host disease may also develop, making post-transplant management complex. Once a transplant recipi...

PURPOSE OF REVIEW To review the available clinical and biological advances of umbilical cord blood allogeneic stem cell transplantation in pediatric and adult patients. RECENT FINDINGS Recent large international studies suggested that allogeneic umbilical cord blood transplantation may potentially emerge as the frontline stem cell source for pediatric patients with hematopoietic malignancies ...

Aplastic anemia, an unusual hematologic disease, is the paradigm of the human bone marrow failure syndromes. Almost universally fatal just a few decades ago, aplastic anemia can now be cured or ameliorated by stem-cell transplantation or immunosuppressive drug therapy. The pathophysiology is immune mediated in most cases, with activated type 1 cytotoxic T cells implicated. The molecular basis o...

introduction: bronchiolitis obliterans (bo) is one of the most important pulmonary complications of hematopoietic stem cell transplantation (hsct). we decided to evaluate the prevalence and risk factors of bo in hsct patients in the shariati hospital oncology research center. materials and methods: forty two patients, who had had hsct for at least 6 months ago, completed the study. the diagnosi...

purpose: to report the clinical findings and compare the outcomes of different surgical techniques evolved over time in a large series of patients with delayed-onset mustard gas keratitis (mgk). methods: this interventional retrospective case series includes patients with complications of delayed mgk. medical and surgical interventions to address dry eye, limbal ischemia and limbal stem cell de...

BACKGROUND In severe acquired aplastic anemia, hematopoietic failure is the result of immune-mediated destruction of bone marrow stem and progenitor cells. Immunosuppressive therapy with antithymocyte globulin (ATG) plus cyclosporine is an effective alternative to stem-cell transplantation and improves blood counts and survival. Although horse ATG is the standard therapy, rabbit ATG is more pot...

Overall survival in severe aplastic anemia has markedly improved in the past four decades due to advances in stem cell transplantation, immunosuppressive therapies and supportive care. Horse anti-thymocyte globulin plus cyclosporine is the standard immunosuppressive regimen in severe aplastic anemia, and often employed as initial therapy as most are not candidates for a matched related stem cel...

abstract spinal cord injury (sci) is a devastating condition producing great personal and societal costs and for which there is no effective treatment. stem cell transplantation is a promising therapeutic strategy, though much preclinical and clinical research work remains. here, we briefly describe sci epidemiology, pathophysiology, and transplantation trial in human developments, including te...
