Filter by:Background: Severe aplastic anemia (SAA), and myelodysplastic syndrome (MDS), and paroxysmal nocturnal hemoglobinuria (PNH) cause serious blood problems. Stem cell transplants using bone marrow or blood plus chemotherapy can help. Researchers want to see if using peripheral blood stem cells (PBSCs) rather than bone marrow cells works too. PBSCs are easier to collect and have more cells that help transplants. Objectives: To see how safely and effectively SAA, MDS and PNH are treated using peripheral blood hematopoietic stem cells from a family member plus chemotherapy. Eligibility: Recipients ages 4-60 with SAA, MDS or PNH and their relative donors ages 4-75 Design: Recipients will have: - Blood, urine, heart, and lung tests - Scans - Bone marrow sample Recipients will need a caregiver for several months. They may make fertility plans and a power of attorney. Donors will have blood and tissue tests, then injections to boost stem cells for 5-7 days. Donors will have blood collected from a tube in an arm or leg vein. A machine will separate stem cells and maybe white blood cells. The rest of the blood will be returned into the other arm or leg. In the hospital for about 1 month, recipients will have: - Central line inserted in the neck or chest - Medicines for side effects - Chemotherapy over 8 days and radiation 1 time - Stem cell transplant over 4 hours Up to 6 months after transplant, recipients will stay near NIH for weekly physical exams and blood tests. At day 180, recipients will go home. They will have tests at their doctor s office and NIH several times over 5 years.
This is a single arm pilot study using TCR alpha/beta+ T cell-depleted peripheral blood stem cells (PBSC) from closely matched unrelated donors or partially matched/haploidentical related donors for hematopoietic stem cell transplant (HSCT) in patients with acquired and inherited bone marrow failure (BMF) syndromes.
This is a study to collect the outcomes of stem cell transplantation for patients with hematologic diseases other than cancer.
This study is a collection of data to evaluate safety and characterize progression of Paroxysmal Nocturnal Hemoglobinuria (PNH).
Paroxysmal nocturnal hemoglobinuria (PNH) is a hematopoietic stem cell disorder in which unregulated activation of the complement system leads to significant ischemic morbidities with shortened lifespan. Life-threatening thromboembolism (TE) is the most feared complication of PNH, accounting for up to 45% of patient deaths. It is estimated that 40% of PNH patients experience a clinically evident TE and 60% of patients without clinically diagnosed TE demonstrate TE by high-sensitivity MRI, indicating the ongoing thrombotic risk in most patients with PNH. Much of these data come from PNH patients from European descent. To understand the impact of TE in patients with PNH from non-European regions, we performed this study to evaluate the clinical characteristics of Korean patients with PNH.
