Study of genetics and causes of systemic juvenile arthritis and Still's disease
This study aims to learn more about the causes and genetics of two related inflammatory conditions: systemic juvenile idiopathic arthritis (sJIA) in children and adult-onset Still's disease (AOSD) in adults. By studying patients and healthy volunteers, researchers hope to understand these diseases better and find better ways to treat them.
Bethesda, MarylandAges 1 day–100 years - NCT02769975Recruiting
Check children and teens with hormone and metabolism problems
This study evaluates children (and sometimes relatives) who may have hormone (endocrine) or metabolism-related conditions. It helps doctors better understand these problems by doing a clinical evaluation.
Bethesda, MarylandAges 3 months–100 years - NCT02579967RecruitingPhase 2
Stem cell transplant for primary immune system disorders
This study tests whether an allogeneic stem cell (bone marrow) transplant can correct an inherited immune problem in people with severe primary immunodeficiencies. It may help reduce life-threatening infections and improve quality of life, depending on your overall health and donor match.
Bethesda, MarylandAges 4–75 - NCT00001539Recruiting
Lyme disease study's treatment and recovery health
This study looks at the health of people who have had Lyme disease, including those with ongoing symptoms after treatment, and those who have recovered or never had it. It aims to understand the disease and find better ways to manage it.
Bethesda, MarylandAges 13–99 - NCT00001406Recruiting
Understanding eosinophil behavior in rare blood and tissue conditions
This research study examines how eosinophils (a type of white blood cell) behave and function when they become abnormally high in the blood or tissues. Researchers want to understand these conditions better to potentially improve treatment options.
Bethesda, MarylandAges 1–100 - NCT07877519Recruiting
Sedation options for pulsed field ablation in atrial fibrillation
This study compares two ways to keep patients comfortable during a procedure called pulsed field ablation for atrial fibrillation: conscious sedation (you're awake but relaxed) versus general anesthesia (you're fully asleep). The goal is to find which method works better and is safer for patients.
