Arterial Function Parameters and Transcranial Doppler Velocity in Paediatric Patients With Sickle Cell Disease
Structural and functional changes in arteries are increasingly being recognized as significant features of sickle cell disease. This study aims to determine whether there are differences in arterial function parameters between children with sickle cell disease with normal and abnormal transcranial Doppler velocity. After informed consent is obtained, participants will …
Molecular and Cellular Basis of Severe Forms of Dengue in Sickle Cell Patients
Dengue virus (DENV) belongs to the genus of Flavivirus transmitted by the mosquito Aedes aegypti and is responsible for an infectious disease associated with different forms and severities such as dengue hemorrhagic fever or shock syndrome. Several recent reports have shown that sickle cell patients exhibited an increased risk of …
Serial Assessment of Fertility Experiences
The SAFE study is a long-term research project that watches people with sickle cell anemia (SCA) over time. The main goal is to see how a medicine called hydroxyurea affects their growth, puberty, and ability to have children. A second goal is to see how hydroxyurea affects pregnancy outcomes, by …
Observational Study to Deeply Phenotype Major Organs in Sickle Cell Disease After Curative Therapies
Background People with sickle cell disease (SCD) have problems with their heart, brain, kidneys, liver, and lungs as they age. These problems may improve after transplant. Researchers want to learn how and why this happens. Objective To study the benefits of treatments that are intended to cure SCD. Eligibility People …
Verifying Antibodies After Live Immunization Delivery (VALID): A Study of Measles Vaccine Immunogenicity in Children With Sickle Cell Disease
The goal of this study is to learn if infants with sickle cell disease (SCD) develop adequate protection after measles vaccines. (not looking at any prolonged duration)
Collection of Human Biospecimens for Basic and Clinical Research Into Globin Variants
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 …
A Pilot Study on Neuroimaging in SCD: Part of The Boston Consortium to Cure Sickle Cell Disease
Sickle Cell Disease (SCD) impairs oxygen transport to tissue and causes endothelial injury. Thus, therapeutic interventions aim to improve both, but there is an unmet need for biomarkers to determine when intervention is necessary and evaluate the effectiveness of the chosen intervention in individual patients. This study proposes to monitor …
Functional Ovarian Reserve in Sickle Cell Disease
This study aims to look at AMH levels in female children with SCD as they go through puberty to see if they are at the same level as other children without SCD at the same age and/or pubertal stage and will also look at how treatment exposures and pain crises …
Study of Erythrocyte Parameters and Hypercoagulability in Sickle Cell Disease (SCD-TGA)
Sickle cell disease (SCD) is an inherited haemoglobinopathy disorder caused by mutations in HBB gene with amino-acid substitution on β globin chain. The consequence is synthesis of altered haemoglobin S (HbS) which polymerises in red blood cell (RBC) at deoxygenated state. SCD is associated with chronic haemolytic anaemia, vaso-occlusive crisis …
PASS of Xromi Comparing Safety and Effectiveness in Children Under 2 Years With Sickle Cell Disease [PRECISE PASS]
This post-authorisation safety and efficacy study (PRECISE PASS) evaluates the use of Xromi® (hydroxycarbamide 100 mg/mL oral solution) in children aged 9 months to under 2 years with sickle cell disease (SCD).The objective is to assess the safety profile and clinical effectiveness of Xromi® under routine clinical conditions. The study …
