What Is This Study About?
Helicobacter pylori (H. pylori) is a common bacterial infection that affects the stomach. While antibiotics are the standard treatment, they don't always work the first time. This study is for individuals who've already tried one course of antibiotics but still test positive for H. pylori.
Purpose of the Study
This study explores whether the Esophageal String Test (EST), a simple, less invasive procedure can accurately detect H. pylori and antibiotic resistance, compared to traditional testing that uses endoscopic biopsies.
What Will Happen if You Participate?
Participation includes up to 4 in-person visits at the NIH and phone check-ins. Study activities include:
- Physical exam & medical history
- Vital signs check
- Stool sample collection
- Esophageal String Test (EST)
- A possible second course of antibiotics
- Endoscopy (only if needed)
Cost
There is no cost to participate.
Potential Benefits
Your involvement could help improve H. pylori testing for future patients making it simpler, faster, and less invasive.
