Summary
This trial is testing a tool to measure changes in oxygen levels, blood flow, and the makeup of skin and muscle in people aged 18+ with sickle cell disease. Healthy volunteers are also needed. Participants will have physical exams, tests, and blood draws.
Who is the study for?
This trial is for adults with Sickle Cell Disease (SCD), including those on stable Hydroxyurea treatment. Healthy individuals are also needed for comparison. Pregnant women, people who can't walk for 6 minutes due to mobility issues, recent users of certain SCD medications, and those with specific surgical histories or blood transfusions are excluded.
What is being tested?
Researchers are testing Near Infrared Spectroscopy (NIRS) as a non-invasive method to measure muscle oxygen levels, blood flow, and tissue composition in patients with SCD compared to healthy controls. The study involves physical exams, NIRS tests during various activities, and up to five visits.
What are the potential side effects?
Since the intervention involves non-invasive imaging technology without medication administration or invasive procedures, significant side effects aren't expected. However, discomfort from wearing probes or having a blood pressure cuff inflated might occur.
