This study tests a 7-day treatment for H. pylori, a stomach bacteria that can cause ulcers. About 316 adults with H. pylori will get either the new 7-day combo (vonoprazan, amoxicillin, and bismuth) or the standard 14-day therapy. The goal is to see if the shorter treatment works…

This study tests a new method to treat H. pylori, a stomach infection, during an endoscopy. The stomach is filled with a saltwater solution that is treated with a special gas (argon plasma) to kill the bacteria. The study involves 20 adults with untreated H. pylori and compares t…

This study tests whether a newer acid-reducing drug (vonoprazan) works better than a standard one (esomeprazole) for clearing H. pylori infection. About 80 adults with stomach discomfort will take one of the two treatments for 14 days. Four weeks later, a stool test checks if the…

This study compares a new, less invasive test called the esophageal string test (EST) to standard methods for diagnosing H. pylori, a stomach bacteria that can cause ulcers and cancer. About 25 adults with persistent H. pylori infection will swallow a capsule with a string that c…

This study compares a new stool test that looks for high-risk gene changes in H. pylori bacteria with a standard risk questionnaire to see which method finds stomach cancer earlier. Researchers will enroll 15,000 adults aged 40 and older. Participants will provide a stool sample …

This study looks at how common Helicobacter pylori infection is in people newly diagnosed with stomach cancer in Martinique. Researchers will collect tumor samples, healthy tissue, and blood to build a biobank. The goal is to understand why stomach cancer is more common in the We…

This study looks at how the H. pylori bacterium is distributed in different stages of stomach inflammation and early stomach cancer. Researchers will examine tissue samples from 231 adults aged 18-80 who tested positive for H. pylori. The goal is to find patterns that could help …
