Gastrointestinal tuberculosis

This study tests whether using early drug monitoring and a dose-adjustment calculator can help infants under 90 days old with sepsis reach target vancomycin levels more quickly. Currently, doctors must wait 24-48 hours to check drug levels, which can delay effective treatment. Th…

This study is testing whether a powerful antibiotic called piperacillin/tazobactam can be given as a continuous shot under the skin instead of through an IV line. About 240 adults with serious bacterial infections will be randomly assigned to receive the drug either subcutaneousl…

This study compares two ways of giving the antibiotic cefepime to very sick patients with sepsis in the ICU. The new method adjusts the dose based on the patient's kidney function, using only standard doses. The main goal is to see if this approach is easy for doctors to use and …

This study tests whether giving zinc supplements along with standard antibiotics can reduce deaths and improve recovery in young infants (0-59 days old) hospitalized with severe infections like sepsis or pneumonia. About 3,250 babies in Tanzania will receive either zinc or a plac…

This study is developing an artificial intelligence system that analyzes CT and MRI scans to diagnose and predict outcomes for digestive diseases like Crohn's disease, ulcerative colitis, and intestinal tuberculosis. Researchers are using data from 21 hospitals in China to train …

This early study is testing a radioactive tracer called [18F]F-TMP that is injected into the body and then tracked with a PET/CT scan. The goal is to see if the tracer collects at sites of bacterial infection, making them visible on the scan. Twenty adults with known or suspected…

This study tests whether giving antibiotics through a small, portable pump over 24 hours is safe and cost-effective for children with serious bacterial infections. About 150 kids who are stable enough for home care will receive the pump instead of multiple daily hospital injectio…

This study looks at how the immune system changes with age and how that affects the risk of infections in people 60 and older. Researchers will collect blood, urine, stool, and other samples from elderly patients with infections and healthy older adults. By analyzing immune cells…

This study aims to improve how doctors evaluate and manage people who have been exposed to bioterrorism agents (like anthrax) or emerging infectious diseases (like SARS or new flu strains). Up to 200 participants, including patients and healthcare workers, will be monitored and t…

This study aims to collect medical data and biological samples (blood, urine, stool, and tissue) from up to 4,000 adults with known or suspected gastrointestinal diseases. Participants receive standard medical care at the NIH, and any extra samples or leftover tissue from procedu…

This study is testing a new rapid diagnostic device called In-Dx to quickly identify infections and antibiotic resistance in emergency patients with suspected sepsis. Researchers will compare the device's results to standard lab cultures using stored samples from 2,500 patients. …

This study compares two strategies for finding undiagnosed tuberculosis (TB) in peri-urban Uganda. One strategy sets up screening at a large health clinic, while the other sends mobile screening teams into local hotspots where TB is thought to be most common. Researchers will tra…

This study is observing 1,000 people with liver cirrhosis who have bacterial infections and are being treated with β-lactam antibiotics. Researchers want to see how the body processes these drugs and whether personalized dosing could improve survival. The study is observational, …

This study looks back at 15 years of medical records and will also follow new patients with intestinal tuberculosis to find out which factors—like age, other illnesses, or treatment habits—make death more likely. Researchers will collect data from 500 adults diagnosed with intest…

This study tests a new, lightweight ultrasound device called NeoDoppler that can be gently placed on a newborn's soft spot (fontanelle) to continuously measure blood flow in the brain. Researchers will enroll 180 preterm and full-term infants, including those with conditions like…

This study is looking at whether early signs of inflammation in the blood can help identify which patients with infections are at risk for serious complications like sepsis. Researchers will follow 4,200 adults with confirmed or suspected infections, as well as healthy controls, …

This study explores whether measuring tiny DNA fragments from the TB bacteria in the blood can help doctors monitor how well treatment is working. Researchers will enroll 140 adults with newly diagnosed TB in Thailand, taking blood samples over time to see if the DNA levels drop …

This early-stage study is testing whether a single dose of an experimental antibiotic combination (sulopenem etzadroxil plus probenecid) is safe and tolerable in 12 adolescents already receiving standard antibiotics for a bacterial infection. Researchers will measure how the drug…

This study looks at how the antibiotic ceftazidime avibactam behaves in 30 children with severe infections who are in intensive care, some on life support. Researchers will measure drug levels in the blood to understand the right dose. The goal is to improve treatment for life-th…

This study looks at how the antifungal medicine caspofungin behaves in children with severe infections, especially those with liver problems or on life support like ECMO. Researchers will measure drug levels in the blood to understand dosing needs. About 60 children in intensive …

This study will collect data from 2,000 children admitted to pediatric intensive care units (PICUs) with severe infections across major Chinese cities. Over 10 years, researchers will track which germs cause these infections, how they are treated, and patient outcomes. The goal i…

This study looks at two common antibiotic combinations given to hospitalized adults with infections: vancomycin plus piperacillin-tazobactam, or vancomycin plus cefepime. The goal is to see if one is less likely to cause kidney injury than the other, using more sensitive markers …

This pilot study is testing whether a smart wristband can accurately measure drug levels in sweat compared to standard blood tests. Researchers will collect sweat, saliva, and blood samples from 100 patients with chronic or infectious diseases who are taking medications like cycl…

This study is looking for new ways to diagnose sepsis, a life-threatening reaction to infection, earlier in the emergency room. Researchers will study the immune responses of 3,300 adults with suspected infections to find patterns that signal sepsis. The goal is to improve diagno…
