Clinical Trials

Are you an adult who does not have high blood pressure and is interested in research? This study will investigate how the brain regulates the body’s response to stress and how infection with HIV or pre-hypertension affects regulation. Your heart and brain activity will be measured while you are at rest, during a mentally stressful task, and while you feel angry. The study will also test whether a breathing exercise improves regulation. People with and without HIV and pre-hypertension will be included. To participate in this study, you must be between 21 and 65 years old and not have high blood pressure. This study is located in Miami, Florida.

This is an observational - data and specimen collection study. There have been increasing reports of vaping-induced lung injury, including severe lung injury and rare cases of death. The mechanism by which vaping contributes to lung injury in susceptible persons is unknown, as is impact on chronic lung disease. The investigators aim to identify individuals with chronic electronic nicotine delivery device (ENDD) exposure and matched controls within our ongoing cohort of HIV+ and HIV-uninfected individuals, collect PFT data, bank respiratory and stool samples and collect clinical data for studies of clinical risk, inflammation, biomarkers, and the microbiome in the identification and modification of risk of progression to lung injury or chronic pulmonary disease.

The overall goal is to assess the potential of the radiotracer to track inflammatory cells in lung diseases.

Have you or your child been diagnosed with a blood disorder? If so, you (or they) may be able to participate in a clinical study where researchers are studying a type of infusion using cord blood. Participants can be of any age but must have a blood disorder diagnosed by their doctor. The study is taking place in locations in Alabama, Arizona, California, Colorado, Delaware, Florida, Georgia, Illinois, Indiana, Kentucky, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Nebraska, New York, Ohio, Oklahoma, Oregon, Pennsylvania, South Carolina, Tennessee, Texas, Virginia, Washington, Washington, D.C., West Virginia, and Wisconsin.

Do you or your child have an immunodeficiency, such as fewer T cells or NK cells? You can help researchers better understand how some types of immunodeficiencies are inherited. Participants in this study must be at least 6 months of age. This study is located at the NIH Clinical Center in Bethesda, Maryland.
