Stool test guided therapy for H. pylori infection

This trial studies how to eradicate Helicobacter pylori (a germ in the stomach) and monitor follow-up results after treatment. You may be a candidate if you have confirmed infection and have not taken certain stomach medicines or antibiotics recently.

This trial tests a simpler two-drug treatment for H. pylori infection, chosen based on a stool test that checks if the bacteria are resistant to clarithromycin. It may help people who have not been treated before avoid unnecessary antibiotics.

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.

This study tries a fecal microbiota transplant (placing healthy donor stool into your gut) to get rid of stubborn H. pylori infection that hasn't been cured by standard treatments. It's for people who have failed several rounds of therapy and have a stomach condition that makes eradication important.

This trial compares a personalized treatment approach to the standard one for H. pylori infection. If you are scheduled for an upper endoscopy and need biopsies, you may be able to join.

This trial studies whether using lab testing to guide antibiotic choice works better than using a standard (empirical) treatment plan for stubborn H. pylori infection. You might benefit if past treatments have not cleared the infection after multiple attempts.
