This study tracks people with KICS, a condition caused by KSHV (a virus related to Kaposi sarcoma). It aims to understand the syndrome better and may lead to future treatments.
Bethesda, MarylandAges 18–120 - NCT01306084Recruiting
Study of viral infections in healthy and immune-compromised people
This trial studies how viruses affect the body, and how the immune system responds, in both healthy people and people with weakened immunity. It may include people who currently have a suspected or recent viral infection, close contacts, people around the time of a viral vaccine, and healthy adults used for comparison.
Bethesda, MarylandAges 6 months–120 years - NCT01730131Recruiting
Study of PML in patients, at-risk people, and healthy volunteers
This study follows people with suspected or confirmed progressive multifocal leukoencephalopathy (PML), people at higher risk, and healthy volunteers. It uses visits, brain imaging (MRI), and stored biological samples to better understand how PML progresses and who is at risk.
Bethesda, MarylandAges 2–120 - NCT01553214RecruitingPhase 4
Blood donation study to improve white blood cell collection
This study tests a better way to collect white blood cells from healthy people who donate blood. It may help improve how reliably and safely white blood cells are collected for research or future treatments.
Bethesda, MarylandAges 18–75 - NCT02154035Recruiting
Measuring HIV reservoir in Ugandans with suppressed virus
This study in Uganda looks at the HIV 'reservoir' (where the virus hides in the body) in people whose HIV is already well-controlled with medications. It involves blood draws and genetic testing to learn more about the virus.
KalisizoAges 18–49 - NCT01386437Recruiting
Study immune problems and fungal infections
This study looks at how immune system problems relate to fungal infections, using medical records and lab tests on blood and tissue. It may help researchers understand the cause of these infections—especially for people with inherited immune conditions—and improve future care.
Bethesda, MarylandAges 1 day–99 years - NCT01933620Enrolling by invitation
NIH study of the microbiome using stored body samples
This study looks at the community of microbes in the body (your “microbiome”) using samples like stool, urine, and possibly tissue. It may help researchers understand how these microbes relate to health in hospital patients.
Bethesda, MarylandAges 2–120 - NCT02140255RecruitingPhase 1/Phase 2
Intensive early HIV treatment in newborns to aim for remission
This study gives very early, intensive HIV medicine to infants diagnosed with HIV and follows them closely to see if HIV can go into remission (stop being detectable without ongoing treatment). It may help families understand whether treating right after birth can change a child’s long-term HIV outlook.
La Jolla, CaliforniaAges Up to 2 days - NCT01875588Recruiting
Long-term study of thinking and memory in adults with HIV
This study looks at how thinking and memory change over time in adults with HIV and compares them with adults without HIV. Researchers will do regular visits and brain/cognitive testing to understand what affects thinking and memory and to learn what might help.
Bethesda, MarylandAges 18–110 - 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 - NCT01386424Recruiting
Healthy adult check-in for future infectious-disease volunteer studies
This study enrolls healthy adults to help set up future research studies about infectious diseases. If you qualify, you may be asked to join later “healthy volunteer” experiments and allow your samples to be stored for future research.
Bethesda, MarylandAges 18–65 - NCT01520844Recruiting
HIV cohort study comparing people on and off treatment
This study follows adults with HIV over time to compare different groups based on how stable their virus levels are. It may help researchers understand who can safely interrupt treatment and who should stay on it, and how immune health changes.
Le Kremlin-BicêtreAges 18–85 - NCT01374984Enrolling by invitation
Test VIGIV treatment for serious complications from smallpox vaccination
This trial looks at how well a medicine called VIGIV works for people who develop serious or unusual vaccinia (smallpox-type) infections or complications after smallpox vaccination. It is mainly for specific skin and body-area problems, including eczema-related complications.
Ages Any age - NCT02051062Enrolling by invitationPhase 4
Blood-plasma study of botulism antitoxin in children
This trial studies how a botulism antitoxin (called BAT, heptavalent) moves through the body in children. It may help doctors better choose doses and timing for pediatric treatment by learning from blood samples after the first dose.
Ages 1 day–11 years - NCT01280825Recruiting
Testing how to use genetic medicine results in routine care
This study looks at how to put genetic testing results (pharmacogenomics) into regular doctor care. It aims to see whether using the results helps doctors choose safer, better-matched medications.
Chicago, IllinoisAges 18 years+ - NCT01868373Enrolling by invitationPhase 1
Fecal transplant study for hard-to-treat C. difficile diarrhea
This Phase 1 study tests defined fecal microbiota (healthy gut bacteria) given to people with C. difficile diarrhea that didn’t go away or came back soon after antibiotics. It may help by restoring a healthier balance of gut bacteria so the infection can stop recurring.
Houston, TexasAges 18 years+ - NCT02038166Recruiting
Measuring nasal function in adults with chronic sinus symptoms
This study tests a specialized way of measuring how your nasal lining responds in people with chronic rhinosinusitis (long-lasting sinus inflammation). The goal is to see whether the nasal measurement is usable and safe, and to help better understand chronic sinus disease.
Birmingham, AlabamaAges 18 years+ - NCT02127398RecruitingPhase 2
Fecal transplants for hard-to-treat C. difficile infection
This Phase 2 study tests whether placing stool from a healthy donor into your gut can treat repeated, hard-to-control C. difficile colitis. It may help restore healthy gut bacteria and reduce future flare-ups.

Study for children with strep throat using beta-lactam antibiotics
This study looks at children ages 5–15 who test positive for Group A strep (often called strep throat). It may help by testing an antibiotic approach with beta-lactam medicines for children who are expected to need treatment.
Madison, WisconsinAges 5–15 - NCT02139163Recruiting
