Filter by:Human participants affected with sickle cell disease or thalassemia will donate bone marrow for use in experimental laboratory models to study potential new treatments. This is an observational study using bone marrow from human participants. The investigators will use sickle cell and thalassemia mouse models to observe and evaluate the possibility of correcting these disorders through genetic alterations or drug treatment.
Sickle cell disease (SCD) is a blood disorder that is characterized by intense, painful episodes known as sickle cell crises. This study will evaluate the effectiveness of PAINRelieveIt, a three-part computer-based pain management tool, in treating adults with SCD.
The purpose of this study is to evaluate the FIM™ as a measure of daily function in children with sickle cell disease hospitalized with vasoocclusive pain. Currently, the standard for pain assessment is a rating of pain intensity, as determined by observation (for younger children) or self-report (for older children and adolescents). However, these measures of pain intensity are not effective in recurrent or chronic pain states, and in sickle cell disease in particular. Pediatric patients who are hospitalized with vasoocclusive pain often do not report a decrease in pain intensity; however, other indications of clinical status, such as ambulation, less use of opiates from the patient-controlled analgesia (PCA) pump, increased food intake, and transition to oral pain medication, signify that the patient may be improving. As a result of our inability to get an accurate picture of the patients' condition, we would like to have a summary of improvement that would reflect these changes in clinical status and reflect the reduced impact of sickle cell pain on the patient's life. In this study, we plan to evaluate a standardized functional assessment measure in pediatric patients with sickle cell disease. It is hypothesized that FIM™ scores will correlate with other indicators of clinical status, such as movement, quality of sleep, use of IV opiates from the patient-controlled analgesia (PCA) pump, and use of intravenous vs. oral pain medications. It is also hypothesized that the FIM™ will demonstrate adequate responsiveness to change in functional status within a 3-7 day hospitalization by a progressive increase in scores and associations with other indicators of clinical improvement.
The purpose of this study is to determine and confirm the role of bone marrow transplantation in the treatment of disorders of the red cell and hemoglobin including sickle cell anemia, thalassemia and diamond blackfan anemia.
Sickle cell disease (SCD) is the most common inherited disease of the world affecting African and Caribbean populations. SCD is caused by the homozygous inheritance of the gene for sickle hemoglobin (HbS). Most patients with SCD develop abnormal pulmonary function characterized by airway obstruction, restrictive lung disease, abnormal diffusing capacity, hypoxemia and pulmonary hypertension In healthy subjects, lung capillary blood volume (Qc) and membrane diffusing capacity (Dm) can be accurately measured by the nitric oxide-carbon monoxide (NO-CO) method. We propose to study, for the first time, lung capillary blood volume and alveolar membrane diffusing capacity, using the NO-CO method, in children with SCD aged of at least 6 years Early determination of lung function and pulmonary circulation in children with SCD is very important, not only for the understanding of physiopathologic mechanisms of the disease but also for a better therapeutic management of these children.
Sickle cell disease (SCD), also known as sickle cell anemia, is an inherited blood disease that can cause intense pain episodes and may lead to organ failure. Preliminary studies have shown that adults with SCD may have brain abnormalities that contribute to problems with cognitive functioning, including attention and memory difficulties. This study will use brain magnetic resonance imaging (MRI) and neuropsychological testing to examine the differences in cognitive functioning in adults with SCD and adults without SCD. 212 subjects participated in this cross-sectional study consisting of screening questionnaires, a neuropsychological testing battery, and MRI testing. Enrollment into this study ended in May 2008.
The purpose of this study is to asses prospectively the safety and efficacy of hydroxyurea therapy in children with Sickle cell Anemia between ages 18 months and 5 years, with special emphasis on the ability of hydroxyurea to prevent or reverse chronic organ damage.
Sickle cell disease (SCD), also known as sickle cell anemia, is an inherited genetic disease that can cause intense pain episodes. This study will evaluate the effectiveness of the nutritional supplement arginine at improving blood cell function and disease symptoms in people with SCD.
Iron overload is well study in Thalassemia patients and it's not only related to blood transfusions, since intestinal iron absorption is also increased in those patients. Sickle cell patients didn't developed significant clinical symptoms and signs of iron overload in spite frequent transfusions. The purpose of this study is to assess the iron overload in Sickle cell anemia and Sickle cell Thalassemia patients using clinical parameters and laboratory studies including Non Transferrin Binding Iron, Labile Iron and Hepcidin, in order to determine the cardiac and liver iron.
Iron overload is well study in Thalassemia patients and it's not only related to blood transfusions, since intestinal iron absorption is also increased in those patients. Sickle cell patients didn't develope significant clinical symptoms and signs of iron overload in spite frequent transfusions. The purpouse of this study is to assess the iron overload in Sickle cell anemia and Sickle cell Thalassemia patients using clinical parameters and cardiac T2*MRI in order to determine the cardiac and liver iron.
