Filter by:This study will prospectively investigate the feasibility, safety, and transfusion requirements of adding hydroxyurea to simple chronic transfusions for patients with sickle cell anemia already on chronic transfusions.
Except for children with HIV, all recommendations for treatment of childhood malnutrition are for children < 5 years of age. The overall goal of this randomized controlled nutrition feasibility trial is to identify whether families of children with sickle cell disease (SCD) 5 years and older agree to participate over a 12-week period. The investigators will also establish a safety protocol for monitoring potential complications associated with treating severe malnutrition in children 5 years and older with and without SCD, in a low-resource setting.
This study establishes the safety and efficacy of vit A supplementation doses (3000 and 6000 IU/d) over 8 weeks in children with SCD-SS, ages 9 and older and test the impact of vit A supplementation on key functional and clinical outcomes. Additionally, vitamin A status is assessed in healthy children ages 9 and older to compare to subjects with SCD-SS.
DISPLACE is a three part, multi-center U.S. based study to evaluate the barriers to stroke screening and prevention in children with sickle cell anemia (SCA). In the United States, TCD (Transcranial Doppler ultrasound) is a proven method of screening children with SCA for stroke. However, many children are not getting the screening they need. This study will examine the issues that hinder and help children get the screening at 28 different hospitals and sickle cell centers to improve care for all children with sickle cell anemia. The investigators will then plan a study (part 3) aimed to improve stroke screening and prevention in sickle cell anemia.
Thiotepa is a chemotherapy drug used extensively in bone marrow transplantation. Thiotepa is a prodrug that undergoes metabolic conversion in the liver by CYP2B6 and CYP3A4 to its primary active metabolite, triethylene phosphoramide (TEPA). The goal of this study is to determine what causes some children to have different drug concentrations of thiotepa and TEPA in their bodies and if drug levels are related to whether or not a child experiences severe side-effects during their bone marrow transplant. The hypothesis is that certain clinical and genetic factors cause changes in thiotepa and TEPA drug levels in pediatric bone marrow transplant patients and that high levels may cause severe side-effects.
Melphalan is a chemotherapy drug used extensively in bone marrow transplantation. The goal of this study is to determine what causes some children to have different drug concentrations of melphalan in their bodies and if drug levels are related to whether or not a child experiences severe side-effects during their bone marrow transplant. The hypothesis is that certain clinical and individual factors cause changes in melphalan drug levels in pediatric bone marrow transplant patients and that high levels may cause severe side-effects.
Fludarabine and clofarabine are chemotherapy drugs used extensively in bone marrow transplantation. The goal of this study is to determine what causes some children to have different drug concentrations of clofarabine and fludarabine in their bodies and if drug levels are related to whether or not a child experiences severe side-effects during their bone marrow transplant. The hypothesis is that clinical and individual factors cause changes in clofarabine and fludarabine drug levels in pediatric bone marrow transplant patients and that high levels may cause severe side-effects.
This multi-center study will compare the effectiveness of adding virtual peer mentoring (PM) to a structured education-based (STE) transition program for emerging adults with sickle cell disease to determine its effect on decreasing the number of acute care visits per year, improving patient-reported outcomes, and reducing healthcare utilization among emerging adults with sickle cell disease (EA-SCD)
The purpose of this proposal is to integrate family-centered self-management strategies with mobile health (mHealth) technology to improve reach, self-management behaviors, and child and caregiver physical and psychosocial symptoms and quality of life. Specifically, the investigators propose to conduct feasibility testing of SMYLS, which has been adapted based on user feedback in the first phase of this study. First the investigators will work with the Medical University of South Carolina (MUSC) Pediatric Sickle Cell Clinic to identify and recruit families with children with sickle cell disease (SCD) in the community, statewide. Next, the investigators will test the feasibility of the intervention with 30 dyads of children ages 8 - 17 with sickle cell disease and their parent or primary caregiver, (N=60)
Background: Sickle cell disease (SCD) is a common inherited blood disorder. Many people with SCD are at risk to get pulmonary hypertension (PH). PH means that the blood pressure in the blood vessels to the lungs is high, and is a serious disease and. Very few studies have looked at the success of treatments for PH in people with SCD. Researchers want to learn more about treating PH with a type of drug called phosphodiesterase type 5 inhibitors (PDE5-I). They will look at the records of people who have already joined other studies. Objective: To identify people who already joined NIH SCD protocols whose medical records should be reviewed. The review will look at the description of SCD patients with PH who have already taken PDE5-I and the outcomes for these people. Eligibility: Adults ages 18 and older with SCD and PH. They must have joined certain NIH studies and taken PDE5-I therapy for at least 16 weeks. Design: This study is a review of medical records. Researchers will collect data from databases of existing studies. They will identify people in those studies who have SCD and PH and took the study drug for at least 16 weeks. Researchers will review the full medical records of those people. From that review, researchers will find participants who meet the inclusion criteria. They will extract data from those records. Researchers will analyze the data. This includes results from heart and lung tests, imaging, and walking tests. It will also include results of a procedure called right heart catheterization. Demographic data and lab data will also be collected. Researchers will remove identifying information from the data, then share it in a database.
