Lung fluid and tissue sample collection for research
This study collects samples from your lungs and airways to help researchers better understand lung diseases. It is not a treatment study, but your participation could help improve future care for people with lung conditions.
Bethesda, MarylandAges 5–100 - NCT00339287Recruiting
Healthy adults donate blood to study bacteria-fighting cells
This study looks at how a person’s immune cells interact with bacterial germs. You’d be screened as healthy and may donate blood (and possibly tissue), with samples stored for future research.
Hamilton, MontanaAges 18–120 - 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 - 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 - NCT00001645Recruiting
Evaluation and treatment of parasitic infections
This study evaluates and treats patients who may have a parasitic infection (an infection caused by parasites—tiny organisms that live in or on the body). Researchers will monitor your condition and provide care to help you get better.
Bethesda, MarylandAges 3 years+ - NCT00655096Recruiting
Eye disease study screening for participants and family controls
This trial is a general screening step for people who may have an eye (ocular) condition, or for family members of someone with an eye condition. The goal is to help match you to an eye research study by confirming your situation and whether you can safely participate.
Bethesda, MarylandAges 2–100 - NCT00006518Recruiting
Tissue samples from people with viral infections or cancer
This study collects tissue and blood samples from people who have or have been exposed to certain viruses (HIV, KSHV, HPV, EBV, or HTLV-1) or who have developed cancer or precancerous skin lesions. The samples help researchers understand how these viruses may lead to cancer.
Bethesda, MarylandAges 18–120 - NCT00001372Recruiting
Understanding Lupus: Research Study at NIH
This research study aims to better understand systemic lupus erythematosus (SLE), an autoimmune disease where the body's immune system attacks its own tissues. Researchers will evaluate patients with lupus, study genetic factors, and perform optional imaging tests to learn how the disease affects blood vessels and the heart.
Bethesda, MarylandAges 3–120 - NCT01132859Recruiting
Study of how immune cells respond in adults
This study looks at how your body’s immune system reacts in different tissues by collecting and storing samples for research. You might be able to join if you’re an adult and can consent, and if you don’t have certain bleeding risks that could make sample collection unsafe.
Bethesda, MarylandAges 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.
