Doxycycline to prevent STIs in men who have sex with men
This trial tests whether taking a single dose of doxycycline after sex can prevent common sexually transmitted infections (STIs) like gonorrhea, chlamydia, and syphilis in men who have sex with men (MSM) in Bangkok.

Study of how HIV treatment changes outcomes over time
This is an observational study (not a new drug) that tracks how living with HIV can change over time in different treatment situations. It may help researchers understand long-term effects of the modern “protease inhibitor era” and improve future care.
San Francisco, CaliforniaAges 18 years+ - NCT01904188Recruiting
Rapid identification of infection germs and antibiotic resistance
This study tests whether a faster lab method can correctly identify the germ causing an infection and check which antibiotics may work, using samples taken in the emergency department. It may help doctors choose the right treatment sooner for people with serious suspected infection.
Lansing, MichiganAges 18 years+ - NCT01644903Recruiting
Checking biomarkers after a liver transplant
This study follows people who are getting a liver transplant (including repeat transplants) to monitor changes in their body using test results. It may help doctors understand how patients are doing after transplant and improve care over time.
Chicago, IllinoisAges 18 years+ - NCT00018044Recruiting
Understanding Immune Defects in Mycobacterial Infections
This research study aims to better understand why some people develop unusual bacterial infections (mycobacterial infections) that don't respond well to standard treatments. Researchers will examine your immune system and may study family members to identify genetic factors that increase infection risk.
Bethesda, MarylandAges Up to 100 years - NCT01731353Recruiting
FungiScope study for confirmed invasive fungal infections
This study enrolls people who have test results showing an invasive fungal infection (a fungus causing illness inside the body). The goal is to build a global registry to better understand these infections and improve future care.
Cologne, North Rhine-WestphaliaAges Any age - 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 - 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 - NCT00001230Recruiting
Understanding How Your Body Responds to Filarial Infection
This study looks at how the body's immune system reacts to filarial infections—parasitic worms that affect millions worldwide. Researchers will observe your infection and response to treatment to better understand the disease and improve future care.
Bethesda, MarylandAges 3–100 - NCT01670383Recruiting
Study sample collection for sepsis and after cardiac arrest
This trial collects and stores small samples from people in the ICU who are either being treated for sepsis or who have survived a non-traumatic cardiac arrest. It may help researchers better understand how the body changes after severe infection or after revival, which could improve future care.
SeoulAges 16 years+ - NCT00001205Recruiting
Understanding neurocysticercosis outcomes in treated patients
This study follows patients who have been treated for neurocysticercosis—a brain infection caused by a parasite—to learn how they recover over time and what long-term effects they experience. By joining, you'll help doctors better understand this condition and improve care for future patients.
Bethesda, MarylandAges 3–99 - NCT00404560Recruiting
Blood tests to study infection risk and immune problems
This study looks at how the immune system works in people who have—or might have—an increased risk of infections. It also enrolls their healthy blood relatives so researchers can compare immune features; results may help doctors understand who is at higher risk and why.
Bethesda, MarylandAges 1 month–100 years - NCT01177618Recruiting
Study of early-onset severe COPD in younger adults
This study looks at people who develop COPD (a long-term lung breathing problem) at a younger age and have severe airflow limitation. It may help researchers better understand COPD in early-onset patients and find ways to improve care for this group.
Boston, MassachusettsAges Any age - NCT00029445Recruiting
Blood and Cell Collection Study for HIV Research
This research study collects blood cells from adults with HIV and their family members to understand why some people's immune systems control HIV better than others. Researchers will use your cells to study HIV immunity and develop better treatments.
Bethesda, MarylandAges 18–100 - NCT00001281Recruiting
Understanding how HIV affects blood cells and body fluids
This research study examines how HIV works in the blood and body fluids of people with and without HIV. By studying blood samples, researchers hope to better understand HIV infection and develop better treatments.
Washington D.C., District of ColumbiaAges 18–120 - NCT00557726Recruiting
Evaluation and care for inflammatory or infectious illnesses
This trial helps doctors evaluate possible infection or inflammation and decide on the best management plan. You may be able to receive specialized care at the NIH if the study team thinks your situation fits.
Bethesda, MarylandAges 3–100 - NCT00001316Recruiting
Study viral levels in blood and lymph node tissue with HIV
This study measures how much HIV is in your blood and lymph node tissue. If you qualify, you would also allow blood and other tests (including genetic and hepatitis screening), which may help researchers better understand how HIV affects the body.
Bethesda, MarylandAges 18–100 - 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+ - NCT00001352Recruiting
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.
