The trial is designed to test intravenous (IV) arginine therapy in children with sickle cell disease (SCD) and vaso-occlusive painful episodes (VOE) to further knowledge on efficacy and safety of this orphan drug.
The purpose of the present observational study is to remotely reevaluate the cohort of 67 sickle cell patients with transcranial Doppler-detected cerebral vasculopathy included in the national "Sickle Cell Transplant" protocol and whose 1- and 3-year results were published in JAMA (Journal of the American Medical Association) in 2019 and in BHJ in 2020.
The goal of this clinical trial is to learn if a multifaceted intervention composed of Gazelle-Multispectral sickle cell disease (SCD) point of care testing (POCT) and early initiation of comprehensive SCD care in children with SCD disease aged 0 - 6 months can improve their clinical outcomes.
The main questions it aims to answer are:
The primary goal of the study is to determine the safety and tolerability of ambrisentan. It is also expected that ambrisentan will improve blood flow in the lungs, decrease inflammation, and reduce pain in sickle cell patients. An additional goal is to evaluate the use of select biomarkers in evaluating sickle nephropathy.
Background:
Sickle cell disease (SCD) is an inherited hemoglobin disorder. People with SCD have an increased chance for getting blood clots. Researchers want to see if a dietary supplement called isoquercetin can decrease levels of inflammation and blood clotting in people with SCD.
Objective:
To see how isoquercetin works in people with SCD.
Eligibility:
Adults age 18-70 years old who have SCD and are in a steady-state (have not experienced a pain crisis in the last 60 days and, if taking hydroxyurea, have not had a dose change in the past 90 days).
It is estimated that over 250,000 babies are born with sickle cell disease (SCD) annually in sub-Saharan Africa, and only 10% - 50% of them survive beyond five years of age. Data describing the magnitude of the sickle cell problem are lacking in most African countries. The available data on prevalence were mainly from older studies and small numbers of hospitalized patients. In Uganda, approximately 25,000 children are born with SCD but 70-80% die before their 5th birthday.
This protocol studied the effect of administration of a myeloablative pretransplant preparative regimen followed by an infusion of donor stem cells in children with severe sickle cell disease. The donor graft consisted of bone marrow or cord blood derived from a genetically matched sibling.
This is a clinical trial that will compare survival and sickle related outcomes in adolescents and young adults with severe sickle cell disease after bone marrow transplantation and standard of care. The primary outcome is 2-year overall survival.
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.
Zinc is a nutritionally essential trace element found in previous studies to reduce growth retardation and improve immune function, which may also result in decreased incidence of infectious diseases including malaria, pneumonia and diarrhea. Sickle Cell Disease (SCD) patients are known to be susceptible to zinc deficiency and appear to benefit from zinc supplementation.
