Featured Studies

Researchers at the National Institutes of Health (NIH) are studying if low dose CT scans are as effective as regular CT scans to monitor your disease status. Very low-dose scanning uses about 1/30th the amount of radiation as a regular CT scan.

Doctors at the National Institutes of Health (NIH) are conducting a research study to learn more about the immune system and its response to HIV infection in lymph nodes. All study-related tests and procedures are provided at no cost to the study participant.

Investigators at the National Heart, Lung, and Blood Institute are seeking healthy volunteers, 18-60 years old, who are interested in participating in a study to collect mobilized blood stem cells that will be used in the laboratory to develop new treatments for blood diseases.

Are you from Mexico, Central or South America, or India with hydrocephalus, seizures, or an inflammatory condition of the central nervous system without a diagnosis? The National Institutes of Health (NIH) is studying people with cysticercosis and those likely to have cysticercosis. All study related tests and procedures are provided at no cost to you. Travel to and from NIH may be reimbursed.

The National Institutes of Health seeks healthy volunteers to participate in a research study for the collection of blood components such as platelets and plasma. Doctors are studying new techniques needed to develop gene therapy and other treatments for certain inherited immune system diseases. All participants will be screened with a medical history, physical examination, blood and urine tests.

Are you looking for a treatment for non-alcoholic fatty liver disease (NAFLD) or non-alcoholic steatohepatitis (NASH)? Researchers at the National Institutes of Health (NIH) seek volunteers to participate in a research study. For 30 weeks, participants will receive a medication called semaglutide (typically used for Type 2 diabetes), aiming to improve their liver disease and help them lose weight. The study hopes to better understand liver damage and its treatment in people with these conditions. (En español)

Doctors at the National Institutes of Health (NIH) seek healthy volunteers (with or without a sickle cell trait) and patients with sickle cell for a research study. Sickle cell disease is a genetic blood disorder that occurs mainly in people of African descent. Study participants will have a one-time visit to the NIH to provide blood samples. Researchers hope this study will help us better understand sickle cell disease.

Doctors at the National Institutes of Health (NIH) seek patients with thyroid cancer that spread outside the thyroid - to the lymph nodes, lungs or bones. The standard treatment in such situation is therapy with radioactive iodine (RAI). In this study, doctors will assess a new imaging tool - 124I PET/CT, which enables evaluation of how much iodine goes into the tumor. The study goal is to compare how much iodine goes into cancer cells after two different methods of stimulation of RAI uptake.

Researchers at the National Institutes of Health (NIH) are studying if the medication danazol can be used to treat people with short telomere disease who also have bone marrow failure, liver, or lung disease. In recent studies, danazol, at high doses, showed a positive influence on telomere length. Additional research is needed to learn more about the role of different doses of danazol on telomere disease as well as its effects on secondary diseases.
