Rationale: Chemotherapy administration before a donor stem cell transplant is necessary to stop the patient's immune system from rejecting the donor's stem cells. When healthy stem cells from a donor are infused into the patient, the donor white blood cells can provide the missing enzyme that causes the metabolic disease. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving a monoclonal antibody, alemtuzumab, before transplant and cyclosporine and mycophenolate mofetil before and after transplant may stop this from happening. This may be an effective treatment for inherited metabolic disorders.
Purpose: The design of this study is to achieve donor cell engraftment in patients with standard-risk inherited metabolic diseases with limited peri-transplant morbidity and mortality. This will be achieved through the administration of the chemotherapy regimen described. The intention is to follow transplanted patient for years after transplant monitoring them for complications of their disease and assisting families with a multifaceted interdisciplinary approach.
- To estimate the proportion of patients with donor derived engraftment at day 100 post transplant as defined by 80% or greater donor cells in the CD3 (T cell) fraction
- To determine the rate and severity of graft-versus-host disease (GVHD) by day 100
- To determine the incidence of peri-transplant mortality (death by day 100)
- To monitor donor cell chimerism at various time points following allogeneic transplantation with this transplant regimen as determined at day 28, 42, 100, 6 months and yearly for 5 years.

The goal of this clinical research study is to learn if thiotepa, busulfan, and clofarabine, when given before an allogeneic (bone marrow , blood, or cord blood cells) or haploidentical (b...
The goal of this clinical research study is to learn if busulfan with cyclophosphamide (when given with other helper drugs listed below) can help control the diseases listed above when giv...
Many patients suffering various malignant and non-malignant diseases need hematopoietic stem cell transplantation from a healthy person. In the majority of cases there is no matched relate...
RATIONALE: Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy or radiation therapy used to kill tumor cells. It is not yet known i...
RATIONALE: Giving chemotherapy, such as cyclophosphamide and busulfan, before a donor stem cell transplant helps stop the growth of abnormal cells. It also helps stop the patient's immune ...
We successfully used a haploidentical transplantation protocol with posttransplant cyclophosphamide (CY) (50 mg/kg/d on days +3 and +4) for in vivo T-cell depletion in patients with mucopolysacchari...
Effect of absolute monocyte count post-transplant on the outcome of patients with acute myeloid leukemia undergoing myeloablative allogeneic hematopoietic stem cell transplant with busulfan and cyclophosphamide conditioning.
Peripheral monocytes have recently been evaluated as a prognostic factor in different types of hematological malignancies. This study assessed the prognostic value of absolute monocyte count (AMC) pos...
Busulfan is commonly used as a conditioning regimen before hematological stem cell transplantation (HSCT). There is a big inter-individual variability in busulfan exposure and the narrow therapeutic i...
To determine whether the ocular phenotype in patients with mucopolysaccharidosis type I (MPSI) Hurler is affected by the efficacy of previous haemopoietic stem cell transplantation (HSCT).
There is a substantial lack of data about men's health in adult allogeneic stem cell transplantation.
Transfer of HEMATOPOIETIC STEM CELLS from BONE MARROW or BLOOD between individuals within the same species (TRANSPLANTATION, HOMOLOGOUS) or transfer within the same individual (TRANSPLANTATION, AUTOLOGOUS). Hematopoietic stem cell transplantation has been used as an alternative to BONE MARROW TRANSPLANTATION in the treatment of a variety of neoplasms.
The transfer of STEM CELLS from one individual to another within the same species (TRANSPLANTATION, HOMOLOGOUS) or between species (XENOTRANSPLANTATION), or transfer within the same individual (TRANSPLANTATION, AUTOLOGOUS). The source and location of the stem cells determines their potency or pluripotency to differentiate into various cell types.
The transference of BONE MARROW from one human or animal to another for a variety of purposes including HEMATOPOIETIC STEM CELL TRANSPLANTATION or MESENCHYMAL STEM CELL TRANSPLANTATION.
Transfer of MESENCHYMAL STEM CELLS between individuals within the same species (TRANSPLANTATION, HOMOLOGOUS) or transfer within the same individual (TRANSPLANTATION, AUTOLOGOUS).
Transplantation of stem cells collected from the peripheral blood. It is a less invasive alternative to direct marrow harvesting of hematopoietic stem cells. Enrichment of stem cells in peripheral blood can be achieved by inducing mobilization of stem cells from the BONE MARROW.
Organ transplantation is the moving of an organ from one body to another or from a donor site to another location on the patient's own body, for the purpose of replacing the recipient's damaged or absent organ. The emerging field of regenerative ...
