Tests how clearing H. pylori affects stomach health
Part of Digestive system, Infections clinical trials.
This study follows people with an H. pylori stomach infection over the long term after treatment to see how it changes stomach findings. It may help doctors understand whether eradicating the infection improves stomach health and prevents worsening over time.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have a confirmed H. pylori (stomach) infection
- You are between 18 and 65 years old
- You have not had gastrectomy (stomach removal surgery)
- You are not pregnant or breastfeeding
- You should be able to safely have an endoscopy (a camera to look inside the stomach)

This study follows adults with past or current H. pylori infection to better understand stomach lining changes such as atrophic gastritis and intestinal metaplasia, and to monitor for possible progression. It may help by improving how doctors track risk over time and use stored tissue samples to learn more.
This trial compares the types of bacteria in the stomach of people infected with different strains of H. pylori (CagA positive vs. negative). It may help researchers understand how these bacteria affect health.
This study looks at whether having H. pylori infection (a common stomach bacteria) and certain features of stomach growth can predict how early stomach cancer or pre-cancerous changes will behave and what your long-term outlook might be. You may be eligible if you are being treated with a camera-based removal procedure called endoscopic submucosal dissection (ESD).
This study looks at where H. pylori bacteria are found in the stomach. If you have tested positive for H. pylori through a stomach biopsy and haven't had stomach surgery or serious health issues, you may be able to join.
This study looks at how stomach bacteria (Helicobacter pylori) interact with the normal microbes in your gut. You may be asked to provide tissue, stool, and blood samples to help researchers understand infection and the body’s response.
This study compares two ways to treat Helicobacter pylori (H. pylori) infection that didn’t go away with prior therapy. One approach uses test results to guide which medicines to use, and the other uses standard (“empiric”) treatment. The goal is to see which works better and more safely as a rescue plan.
