Dengue hemorrhagic fever

This study compares two common antibiotic combinations—vancomycin with piperacillin/tazobactam versus vancomycin with meropenem—to see which is less harmful to the kidneys. About 852 hospitalized adults with serious infections will be randomly assigned to one of the two combos. T…

This large study tests several treatments in people hospitalized with moderate or severe dengue. The goal is to find safe, affordable drugs that prevent the disease from getting worse and help patients recover faster. Over 8,800 participants across multiple sites will be enrolled…

This observational study will look at 10,000 adults in intensive care units (ICUs) around the world during a single 24-hour period. Researchers want to find out how common infections and antibiotic-resistant bacteria are, how they are treated, and how patients recover. No new tre…

This research project aims to understand why older adults get more infections and why those infections can be more serious. By following 23,000 people aged 60 and older, scientists will collect health data and samples like blood and stool to study how the immune system changes wi…

This observational study will enroll 190 hospitalized adults with dengue in Bangladesh to see if a 'leaky gut' — where bacteria and toxins escape the intestines into the blood — is linked to severe disease. Researchers will measure gut leakage markers in blood, perform abdominal …

This study will collect blood samples from 30,000 adults in the UK with various health conditions, including blood clots, infections, heart disease, diabetes, and more. The samples will be used to develop and fine-tune new diagnostic tests for the cobas® lumira device, which allo…

This study will follow 300 adults with severe infections in the ICU to see how levels of specialized pro-resolving mediators (SPMs)—natural molecules that help stop inflammation—change over time. Researchers will use blood samples already collected during routine care, so no extr…
