Clinical Trials

The purpose of this research is to determine whether a new stress management and mindfulness program can improve quality of life in individuals with sickle cell disease. The program is based on a number of empirically supported treatments including techniques from cognitive-behavioral therapy like overcoming motivational barriers to self-care, learning to see things as accurately as possible, practicing assertive communication, relaxation exercises like deep slow breathing, mindfulness meditation, and other stress management strategies.

The Sickle Cell Anemia (SCA) is a recessive genetic condition, monogenic, resulting in defects in the red cell structure. In the investigators' country, this disease affects about 3,000 children each year and is considered one of the most prevalent disorders among the group of existing hereditary diseases.

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 aim of the present study is comparing the effectiveness of different treatment regimens for investigating the therapeutic potential for each one in management of Vaso-occlusive pain in pediatric sickle cell disease. In addition, investigators apply the Cost-effectiveness analysis (CEA) as a form of economic analysis that compares the relative costs and outcomes (effects) for different treatment regimens on vaso-occlusive painful crisis.

This study evaluates the safety of defibrotide in subjects with sickle cell disease (SCD)-associated acute chest syndrome (ACS).

Prospective screening and treatment study for children with Sickle Cell Anemia and increased stroke risk living in the Dominican Republic.

Sickle Cell Anemia (SCA) occurs in 300,000 newborns per year in the world, with 150,000 affected births in Nigeria, alone. With improvement in survival for children with SCA in both high- and low-resource countries, neurological morbidity is an emerging significant public health challenge, particularly in countries with a high rate of sickle cell disease (SCD). Both silent cerebral infarcts (SCI) and overt strokes result in significant neurological morbidity and premature death.

Folic acid supplementation (1mg/d) is the standard recommendation for Canadian children with Sickle cell disease (SCD), even though it can provide up to six times the recommended intake amount for healthy children. There is growing concern that too much folic acid can be detrimental to health as high folate levels and circulating unmetabolized folic acid (UMFA), which occurs in blood with doses of folic acid as low as 0.2mg/d, have been associated with accelerated growth of some pre-cancerous cells, and altered DNA methylation and gene expression.

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:

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).
