Filter by:To evaluate the acceptability, tolerance and effect on metabolic control of PKU Start, a new Phe free protein substitute for the dietary management of PKU in infants from birth.
The aim of the trial is to describe the safety and efficacy of intravenous (i.v.) Treosulfan compared to the conventional (myeloablative) dose of i.v. Busulfan, each administered as part of a standardised Fludarabine-containing conditioning regimen and to contribute to a PK model which permits - in conjunction with data comparing Treosulfan and Busulfan in adults with malignant diseases - to extend the use of Treosulfan in the paediatric population by extrapolating efficacy.
Background: - People with inborn errors of metabolism can t turn food into energy the right way. This can affect a person s growth and health. Researchers want to know how this condition affects a pregnant woman and her baby. Objectives: - To collect data from the medical records of women with an inborn error of metabolism. Also, to create a pregnancy registry of inborn errors of metabolism. Eligibility: - Women with an inborn error of metabolism who either: - have been pregnant in the past, - are currently pregnant, or - have recently talked with their doctor about becoming pregnant. Design: - This study will collect data only. No extra tests will be done. - Participants will be in the study for the length of their pregnancy and for 1 year after delivery. - Participants will answer questions about their family s health. - The participant s doctor will send their medical records to researchers. These may include data about: - Last health care visit before pregnancy - Blood, urine, ultrasound, or lab results during pregnancy - Delivery and recovery after delivery - Researchers will ask for the test(s) used to confirm pregnancy. - After the participant has her baby, researchers will ask for data about how the baby is doing. This may include when the baby is sitting, walking, talking, etc. - The data will be placed into a database. The database will not include the participant s name or identifying data.
CD34+ stem cell selection in children, adolescents and young adults receiving partially matched family donor or matched unrelated adult donor allogeneic bone marrow or peripheral blood stem cell transplant will be safe and well tolerated and be associated with a low incidence of serious (Grade III/IV) acute and chronic graft versus host disease (GVHD).
The primary objective is to determine the feasibility of attaining acceptable rates of donor cell engraftment (>25% donor chimerism at 180 days) following reduced intensity conditioning (RIC) regimens in pediatric patients < 21 years receiving cord blood transplantation for non-malignant disorders.
The main purpose of this investigational (not approved by the FDA) Phase I research is to test whether transplantation of umbilical cord blood cells can be safely supplemented with a transfusion of a portion of these cells that have been sorted (collected from a special machine called a cell sorter) and then either infused a few hours after the standard transplant or for some patients grown in a special system in the laboratory prior to the transplant, designed to increase the number of stem cells transplanted. This system is currently in the early phases of testing.
Usual dietary therapies of mitochondrial fatty acid oxidation disorders (FAO) are based on 3 strategies: - limitation of lipid intake in the diet; - supplementation of the diet with medium-chain triglycerides (MCT) for patients affected with disorders of long-chain FAO; - some specific supplementations (for example, L-carnitine). These strategies are often ineffective. The aim of the present study is to evaluate new therapeutic ways based on the underlying energetic defect observed in these disorders. The long-term goal is to develop efficient therapies of these disorders.
We are doing this study to learn more about the early history of universal screening for metabolic disorders such as PKU and galactosemia. In particular, we are interested in learning from our past experience to inform our current plans to expand universal newborn screening. Following standard historical research methodology, we will begin with a review of the historical scholarship on PKU and galactosemia, including more general works on mental retardation, genetics, public health screening, and metabolic disorders. We will also obtain scientific publications and archival sources on the early screening and treatment of these disorders. Lastly, we will conduct oral history interviews with key participants in teh early screening and treatment of PKU and galactosemia.
OBJECTIVES: I. Ascertain whether stem cell transplantation (SCT) is an effective method by which missing or dysfunctional enzymes can be replaced in patients with various inborn errors of metabolism. II. Determine whether clinical manifestations of the specific disease may be arrested or reversed by this treatment.
Hermansky-Pudlak Syndrome (HPS) is an inherited disease that results in decreased pigmentation (oculocutaneous albinism), bleeding problems due to a platelet abnormality (platelet storage pool defect), and storage of an abnormal fat-protein compound (lysosomal accumulation of ceroid lipofuscin). The disease can cause poor functioning of the lungs, intestine, kidneys, or heart. The most serious complication of the disease is pulmonary fibrosis and typically causes death in patients 40 - 50 years old. The disorder is common in Puerto Rico, where many of the clinical research studies on the disease have been conducted. Neither the full extent of the disease nor the basic cause of the disease is known. There is no known treatment for HPS. The drug pirfenidone blocks the biochemical process of inflammation and has been reported to slow or reverse pulmonary fibrosis in animal systems. In this study researchers will select up to 40 HPS patients diagnosed with pulmonary fibrosis. The patients will be randomly divided into 2 groups. The patients will not know if they are taking pirfenidone or a placebo "sugar pill". 1. Group one will be patients who will receive pirfenidone. 2. Group two will be patients who will receive a placebo "sugar pill" The major outcome measurement of the therapy will be a change in the lung function (forced vital capacity). The study will be stopped if one therapy proves to be more effective than the other.
