This study tests whether a 7-day combination of vonoprazan, high-dose amoxicillin, and bismuth can effectively eradicate H. pylori bacteria in the stomach. About 316 adults with H. pylori infection will be randomly assigned to either the 7-day experimental regimen or a standard 1…

This study tests a new way to treat H. pylori, a stomach infection that can cause ulcers. Doctors use a special gas (argon plasma) to treat fluid in the stomach, aiming to kill the bacteria during an endoscopy. The study involves 20 adults with untreated H. pylori. After the proc…

This study tests whether a newer drug (vonoprazan) works better than a standard drug (esomeprazole) when combined with two antibiotics to treat H. pylori infection. About 80 adults with stomach discomfort and confirmed H. pylori will take one of the two treatments for 14 days. Fo…

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 for future studies. The goal is to better understand why stomach cance…

This study looks at where and how much H. pylori bacteria is found in the stomachs of people with different types of gastritis and early stomach cancer. Researchers will review tissue samples from 231 adults to see if the bacteria's location and amount can help spot early signs o…
