Active clinical trials for "Anemia, Sickle Cell"

This study is being done to see if education about medicines directed toward children will improve their knowledge. The investigators also want to know if this knowledge lasts over time. Right now there are few medication instructional cards that are appropriate for children. Most of the medication cards provide information for adults. Some studies have shown that by teaching children directly, the children may take medicine at the right time for the right reason, have fewer side effects and know more about their medicine. The purpose of this research study is to see if education about medication helps children learn more about their medicine and if this knowledge lasts.

With recent advances in gene editing, gene therapy is becoming a viable curative treatment option for sickle cell disease. In order to do genetic manipulation, investigators need to collect hematopoietic stem cells from patients with sickle cell disease. In this study, investigators want to study the safety and feasibility of collecting peripheral blood stem cells from pediatric and young adult patients with sickle cell disease after administering plerixafor. Studying these peripheral blood stem cells will help in optimizing the yield of peripheral CD34+ cells from pediatric and young adult patients with sickle cell disease, which in turn will help to develop better gene therapies for these patients. Primary Objectives Determine the safety profile associated with administration of plerixafor in pediatric and young adult patients with sickle cell disease (SCD). To estimate the number of CD34+ cells/kg of body weight that can be collected with peripheral apheresis after administration of plerixafor in pediatric and young adult patients with SCD. Exploratory Objectives To describe the kinetics of CD34+ cell mobilization in peripheral blood after - + cells obtained from pediatric and young adult patients with SCD. To study the effect of hydroxyurea therapy on senescence in plerixafor-mobilized CD34+ cells obtained from pediatric and young adult patients with SCD.

The long-term goal of this study is to learn if Zoledronic Acid can prevent or reduce pain in sickle cell disease. The goal of this study is to learn about the safety of Zoledronic Acid in persons with sickle cell disease who experience chronic pain requiring medical treatment or use of narcotics.

Patients with sickle cell disease suffer from acute and chronic pain that diminishes their quality of life. The purpose of this study is to assess the feasibility and acceptability of mindfulness meditation, breathing exercises, and gentle yoga therapy as supportive measures for the management of acute vaso-occlusive pain crises in the inpatient setting.

Chronic blood transfusions are essential supportive care for sickle cell patients at high risk for morbidity and mortality due to stroke. These patients, however, are at risk for iron overload. In the investigator's comprehensive sickle cell center, the investigators support chronic transfusion with rapid manual partial exchange transfusions (RMPET) using a single access central line port. The investigators do not have a comprehensive adult sickle cell program but upon transition of patients the patients would be provided simple transfusion (ST) in an adult ambulatory infusion setting due to nursing acuity needed for RMPET. The investigators plan to study the institution's participants currently on chronic transfusion support and compare different transfusion modalities to better understand the effects from switching from RMPET to ST. To date, there are no such comparisons within and between sickle cell patients in the literature.

The purpose of this study is to use cardiac magnetic resonance imaging (CMR) and echocardiographic tissue Doppler imaging to demonstrate a unique restrictive cardiomyopathy of sickle cell disease. The investigators will characterize its frequency and how it might change (e.g., presence/absence and severity) over a 2-year period.

The purpose of this study is to gather decision making needs information from caregivers and patients with sickle cell disease (SCD) in order to develop a web-based decision aid tool. Study subjects will participate in interviews defining treatment decision making needs during which investigators will ask information about their SCD. Notes taken from these interviews will allow the research team to better understand current practice related to clinical practice and allow for better refinement of the decision aid tool. An additional group of participants will be asked to review the web-based Sickle Cell Decision Aid. Participants will be asked to describe thoughts about the site, including but not limited to ease of navigation, content and construction. This study will provide information for the conduct of a randomized controlled trial for the use of a web based decision aid to give patients with sickle cell disease and parent/legal guardian of children with sickle cell disease accurate information about risks and benefits of therapies and enable them to make decisions based on their individual values and preferences.

The aim of this single-center observational study was to evaluate quality of life, clinical effectiveness, and satisfaction in pediatric and young adult patients with sickle cell disease receiving hydroxyurea.

Background: - Some treatments for cancer or other diseases can lead to infertility in women. These treatments include chemotherapy, some stem cell transplants, and pelvic radiotherapy. They are called gonadotoxic therapies. Women can now have their eggs frozen before they have these treatments. This may allow them to get pregnant later. Researchers want to learn more about this technology and processes. Objectives: - To provide egg freezing for women having gonadotoxic therapies at NIH. To learn more about the effects of these therapies. Eligibility: - Women at least 18 years old who are past puberty and before menopause. They must be scheduled to have gonadotoxic therapies. Design: Participants will be screened with medical history and blood and hormone tests. They will also have a physical exam and transvaginal ultrasound. Ovary stimulation: participants will have medications injected under the skin. These increase the chance of fertility. This phase will take about 8 20 days. Participants will have blood drawn and transvaginal ultrasound daily or every other day. Some participants will also have blood thinner injected daily. Egg retrieval: participants will check in to the hospital. Eggs will be removed with a needle during a short surgery. Participants will be awake but sedated. Participants may stay overnight in the hospital. They will return every 1 3 days for 1 3 weeks for blood tests. Mature eggs will be frozen after egg retrieval and immature eggs (which cannot be fertilized for clinical use) will be used for research. Participants can use their eggs in the future at outside, private fertility clinics to try to become pregnant. If the eggs are stored for more than 5 years, participants must pay for storage.

Background: Sickle cell disease is an inherited blood disorder. People with this disease have a problem with their hemoglobin. That is a protein in red blood cells that carries oxygen in the body. Some people with this disease are enrolled in research at NIH. Researchers want to learn more about the thoughts and opinions of those people. This may improve the way researchers explain clinical studies, risks, and benefits to people with the disease. Objective: To learn about the motivations, decisions, and experiences in clinical research of people with sickle cell disease. Eligibility: Adults ages 18 and older who have sickle cell disease. They must be in an NIH study on this condition. They must have been invited to join either a gene therapy or peripheral blood stem cell transplantation study. Design: Participants will have 1 interview. It will be done in a quiet room in the NIH Clinical Center or by video call. It will take about 60 minutes. The interview will be audio-recorded if the participant agrees. Participants will be asked about: Their experiences with and thoughts on sickle cell disease Their decision to participate in clinical research Factors that may have affected their decision to participate. These may include family, disease history, or faith. Participants may complete a few brief questionnaires.
