Understanding Why Some People Get Fungal Infections
This study looks at genetic reasons why some people are susceptible to a serious fungal infection called cryptococcosis. Researchers will collect blood samples and perform genetic testing to understand the immune system differences that make certain individuals more vulnerable to this infection.
Bethesda, MarylandAges 18–99 - 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+ - 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 - NCT00001405Recruiting
Blood Cell Collection Study for Immune and Blood Disorders
This study collects blood cells and bone marrow from people with immune system or blood disorders, and from healthy volunteers. Researchers will study these cells and may convert them into special stem cells (iPS cells) to better understand diseases and develop treatments.
Bethesda, MarylandAges 18–70 - 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 - 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 - NCT00789009Recruiting
Monitoring people with known or suspected HIV infection
This study tests how well researchers can track HIV-related health and immune changes over time by collecting blood and other samples. It may help you and your care team by creating detailed monitoring, even if your HIV diagnosis is new or still being evaluated.
Bethesda, MarylandAges 18 years+ - NCT01905826Recruiting
Study of GATA2 deficiency causes and health outcomes
This natural history study looks at how GATA2 deficiency (a genetic condition) affects health over time. It may help doctors better understand complications and plan future care, and it includes genetic testing and stored samples.
Bethesda, MarylandAges 2–100 - 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 - 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.
