HELICOBACTER PYLORI INFECTIONS

This study tests two ways of taking antibiotics to treat H. pylori, a stomach infection that can cause ulcers. About 240 adults will take tegoprazan twice daily plus amoxicillin for 14 days, but one group takes amoxicillin three times a day and the other twice a day. The goal is …

This study tests two different triple-drug treatments for H. pylori, a stomach infection that can cause ulcers. About 88 adults with a positive stool test will receive either a standard proton pump inhibitor or a newer drug called vonoprazan, with or without zinc. The goal is to …

This study tests whether a 7-day course of antibiotics, chosen based on a stool test, can cure H. pylori infection as effectively as the standard 14-day course. About 544 adults with a first-time H. pylori infection will provide a stool sample to check for drug resistance, then r…

This study is testing a new, non-invasive method to treat stubborn H. pylori stomach infections. Researchers will use a stool test to identify which antibiotics the bacteria are resistant to, then prescribe a personalized combination. The goal is to see if this tailored approach …

This study looks at whether a blood test for H. pylori bacteria and a painless stomach ultrasound can predict dangerous complications like bleeding or holes in the stomach lining. Researchers will study 230 adults with stomach symptoms to see if these simple tests can tell who ne…

This study will look at 100 adults with inflammatory bowel disease (Crohn's or colitis) in Guadeloupe to see how many also have an H. pylori stomach infection. Researchers will use stomach tissue samples taken during routine endoscopy. The goal is to understand if H. pylori is li…

This study looks at two small molecules (miRNA-155 and miRNA-204) in stomach tissue from 100 children with ongoing belly pain. Researchers want to see if these molecules are linked to gastritis and H. pylori infection. No treatment is given—the goal is simply to learn more about …
