Filter by:The purpose of this study is to evaluate the Safety and Efficacy of Gene Therapy of the Sickle Cell disease by Transplantation of an Autologous CD34+ enriched cell fraction that contains CD34+ cells transduced ex vivo with the GLOBE1 lentiviral vector expressing the βAS3 globin gene (GLOBE1 βAS3 Modified Autologous CD34+ Cells) in Patients with Sickle Cell Disease (SCD)
Background: Sickle cell disease is a common inherited blood disorder. Kidney disease is a major cause of problems in people with sickle cell disease. In order to identify kidney problems early and stop the progression of kidney disease, doctors need the most accurate tests to check kidney function. Researchers hope to understand more about how to test for kidney disease in people with sickle cell disease. Objective: To determine which of two different lab tests is the best to measure kidney function in adults with sickle cell disease. Eligibility: People 18 years and older who have sickle cell disease Design: Participants will be screened with a medical history and blood tests. Participants will have up to 3 visits. Participants will collect their urine in a special container over 24 hours. At the first visit, participants will have blood tests. They will bring their container of urine to the visit. They will have an iothalamate test. For the test, they will get a catheter: a small tube will be inserted into a vein. A special contract agent will be injected into the vein. Blood will be collected over the next 4 hours to test kidney function. Participants will return the next day for a second visit. They will have blood tests. They will have an MRI. For the MRI, they will like on a table that slides into a machine that takes pictures of the kidneys. They may have the MRI in a third visit. ...
This study will 1) Evaluate the prevalence of elevated (conditional or abnormal) transcranial Doppler (TCD) velocities in a cross-sectional analysis of children with Sickle Cell Anemia (SCA) living in Tanzania; 2) Obtain longitudinal data on TCD velocities in this population; and 3) Measure the effects of hydroxyurea therapy on TCD velocities and associated primary stroke risk.
Sickle cell disease is very common in Nigeria. Early diagnosis is important to prevent or reduce serious complications from the disease and to enable children stay healthy. To this end, the investigators would like to test a new, simple and quick device called the HemeChip to determine if it can detect whether or not someone has sickle cell disease. The investigators will compare the results obtained with the HemeChip with a standard method of diagnosing sickle cell disease known as Isoelectric focusing (IEF) or High Performance Liquid Chromatography (HPLC).If the investigators show that the new device can differentiate between children who have sickle cell disease and those who don't as successfully as the IEF or HPLC, they estimate a sharp increase in the use of this device in many countries especially in Africa due to its lower cost
This will be a multistate, multicenter clinical study to determine the efficacy and safety of medical cannabis for a wide variety of chronic medical conditions.
The intent of this open-label, multicenter expanded access program (EAP) is to provide early access to voxelotor prior to market authorization
The goal of the study is to evaluate the efficacy and safety of crizanlizumab in SCD patients with priapism.
The purpose of this study is to test the efficacy of a peer support coaching intervention to improve activated chronic illness self-management versus an attention control group in 225 adolescents and young adults with childhood onset chronic conditions.
Background: Blood disorders like sickle cell disease and malaria affect many people around the world. Researchers want to learn more about blood disorders. To do this, they need to collect biological samples from people with blood disorders. They also need to collect samples from healthy people. Objective: To collect samples to use for research on blood disorders. Eligibility: People ages 18-70 who have blood disorders. Healthy volunteers without blood disorders are also needed. Design: Participants will be screened with a medical history, physical exam, and blood and urine tests. Participants will give one or more samples. They will give them over 5 years. They can choose not to give any of the samples: Saliva: Participants will spit into a tube. They may also have the inside of their mouth swabbed. Urine: Participants will urinate into a cup. Blood: Blood will be taken through a needle in the participant s arm. Fat samples: An area on the participant s belly or buttock will be numbed. A small cut will be made into the skin and a small piece of fat removed. Mucus and cells from the lungs: The participant will be sedated. A flexible tube will be inserted through the nose or mouth into the lung airways. These participants will also have a physical exam, chest x-ray, and heart tests after the procedure. ...
The purpose of this research study is to compare two different ways to give opioid pain medicine to treat sickle cell disease pain that is bad enough to go to the emergency department for treatment. One way uses your weight to decide how much pain medicine to give you while in the emergency department. This is called weight based treatment. The other way uses how much pain medicine you take at home and how much medicine you needed during past emergency department visits to decide how much medicine to give you. This is called patient specific treatment.
