Testing how the body responds to endotoxin
This study checks how your immune system (your body’s defense system) reacts to a controlled substance that triggers inflammation. It may help researchers understand why some people have stronger or weaker inflammatory responses.
Research Triangle Park, North CarolinaAges 18–100 - NCT00794352Recruiting
Studying immune brain and nerve conditions with tests and samples
This study looks at how immune-related brain or spinal cord illness shows up using exams, MRI scans, and sometimes a spinal fluid test (lumbar puncture), plus collected blood and other samples. It may help researchers better understand these conditions and improve future diagnosis or treatments.
Bethesda, MarylandAges 1 month–99 years - NCT01222741Recruiting
Study of people with higher risk of fungal infections
This study looks at immune system differences that can make some people get unusual or frequent fungal (fungus) infections. It may help researchers better understand these conditions, and you may be asked to store blood for future research.
Bethesda, MarylandAges 18–85 - NCT00001350Recruiting
Understanding Autoimmune Lymphoproliferative Syndrome
This research study helps doctors understand ALPS, a rare immune disorder that causes swollen lymph nodes and spleen. Participating means providing blood samples and health information so researchers can learn how the condition develops and how to better care for patients.
Bethesda, MarylandAges Up to 99 years - NCT00001281Recruiting
Understanding how HIV affects blood cells and body fluids
This research study examines how HIV works in the blood and body fluids of people with and without HIV. By studying blood samples, researchers hope to better understand HIV infection and develop better treatments.
Washington D.C., District of ColumbiaAges 18–120 - NCT00341237Recruiting
Study linking genes and environment to health risks
This study looks at how your genes and your environment may affect your health. It may help researchers better understand who is most at risk so future prevention and care can be more personalized.
Chapel Hill, North CarolinaAges 18–120 - NCT00246857Recruiting
Screening study for inherited immune system conditions
This study screens people who may have an inherited immune system condition (like problems with immune cell growth or death) and their blood relatives. The goal is to understand the condition better by collecting blood samples for testing.
Bethesda, MarylandAges 1 month–100 years - NCT00404560Recruiting
Blood tests to study infection risk and immune problems
This study looks at how the immune system works in people who have—or might have—an increased risk of infections. It also enrolls their healthy blood relatives so researchers can compare immune features; results may help doctors understand who is at higher risk and why.
Bethesda, MarylandAges 1 month–100 years - NCT00092235Recruiting
Understanding chronic graft-versus-host disease outcomes
This study follows patients who have had a stem cell transplant and developed chronic graft-versus-host disease (a condition where transplanted cells attack the body). Researchers will track your symptoms and collect blood samples to understand what affects how well patients do over time.
Bethesda, MarylandAges 1–120 - NCT00006150Recruiting
Understanding Hyper-IgE Syndrome: Natural History and Genetics
This study follows people with or suspected Hyper-IgE syndrome (a rare immune disorder causing repeated infections and skin problems) to understand how the condition develops, how best to manage it, and which genes are involved. Researchers also welcome healthy relatives of patients to help identify genetic patterns.
Bethesda, MarylandAges 1 month–120 years - NCT00128973Recruiting
Study immune system problems in people with unusual infections
This study looks at how the immune system works in people who have abnormal immune function, often shown by unusual or repeated infections or long-lasting inflammation. It may involve tests using blood samples and storage of blood for future research.
Bethesda, MarylandAges Any age - NCT01087333Recruiting
Share blood samples to help study blood cancers and treatments
This study collects human samples (like blood or other specimens) to learn more about hairy cell leukemia and other leukemias. It also helps researchers develop new lab-made immune-based medicines for cancer treatment.
Bethesda, MarylandAges 18 years+ - NCT00923507Recruiting
Study of blood cancers’ natural course and next treatment needs
This study follows people with certain slow-growing blood cancers (CLL/SLL, LPL/WM, and related conditions) to understand how they progress and what leads to needing treatment. It may help doctors predict changes over time and plan care more effectively.
Bethesda, MarylandAges 18–110 - NCT00001355Recruiting
Understanding immune system cell defects and family patterns
This research study investigates problems with immune system cells called phagocytes that help fight infections. Researchers will study patients with suspected immune defects and their blood relatives to better understand these conditions and develop better care.
Bethesda, MarylandAges 1 month–100 years - NCT00001529Recruiting
Bone marrow cell selection method study for transplants
This study tests improved ways to select and collect bone marrow cells from healthy donors for use in transplants. Researchers are looking for healthy volunteers to donate cells that may help people who need bone marrow transplants.
Bethesda, MarylandAges 18–60 - NCT00943514Recruiting
Study of bronchiectasis and why infections keep coming back
This study follows children (age 5+) and adults with bronchiectasis or ongoing/repeated lung infections to learn what makes infections more likely. It mainly looks at non–cystic fibrosis causes, but may include some related conditions to compare differences.
Bethesda, MarylandAges 5–100 - 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 - NCT01011712Recruiting
Study immune causes of severe viral infections
This study looks at why some people have severe or unusual viral infections, even when they do not have a known immune problem. It collects blood and tissue samples to better understand possible inherited immune issues and may help future diagnosis and treatment.
Bethesda, MarylandAges 2–100 - NCT00605878Recruiting
Skin microbiome study in healthy people and eczema patients
This study looks at the types of germs on the skin (skin microbiome) in healthy people and people with skin conditions, including atopic dermatitis (eczema). Researchers collect skin samples to understand how skin germs differ and how that may relate to skin health.
Bethesda, MarylandAges 2–100 - NCT01186913Enrolling by invitation
Natural history study for severe combined immune deficiency (SCID)
This study follows children and adults with SCID and related immune disorders to understand how the illness behaves over time. It also helps researchers learn which testing results and genetic types of SCID match different treatment plans.
Birmingham, AlabamaAges Any age - NCT00001532Recruiting
How Genes Affect Lung Disease Development
This research study examines how genetic factors contribute to various lung diseases, including alpha-1 antitrypsin deficiency, cystic fibrosis, and chronic obstructive pulmonary disease. Researchers want to understand why some people develop lung disease and how genetics plays a role, which may help improve treatment in the future.
