Small intestinal bacterial overgrowth

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 study looks at whether adding a specific probiotic (containing Enterococcus faecium and Bacillus subtilis) to the antibiotic rifaximin can improve treatment for small intestinal bacterial overgrowth (SIBO), a condition that causes bloating, pain, and diarrhea. About 100 adul…

This study tests a diet rich in soluble fiber and natural osmotic sugars (the SOLOS diet) to see if it improves constipation symptoms in adults with functional bowel disorders like IBS-C. Researchers will track stool frequency, form, and symptom severity in 180 participants. The …

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 study will check 100 adults with chronic pancreatitis or who had part of their pancreas removed. Even though they take enzyme pills, they still have stomach pain, bloating, or diarrhea. Researchers will use breath tests to see if a condition called SIBO (too much bacteria in…

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…

This study will look at 150 infants and children aged 1 month to 4 years who are admitted to a hospital gastroenterology unit with a gastrointestinal disease. The goal is to find out how common electrolyte disturbances (like low sodium or potassium) are in these children. By meas…
