Prevalence and possible role of non-H. pylori Helicobacter species in gastric conditions and cancers

Official title: The Prevalence and the Pathophysiological Role of Non-Helicobacter Pylori Helicobacter Spp. in Well-defined Gastric Diseases and (Pre-) Malignancies

Run by Universiteit Antwerpen · NCT07770126 · Data updated 2026-11-12

Researchers will test stomach tissue from people with functional dyspeasia, various gastritis conditions, gastric cancer, and bariatric patients to see if non-H. pylori Helicobacter species are present.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults undergoing endoscopy or gastric surgery for the listed conditions who have no history of H. pylori infection by serology, biopsy, breath test, or stool antigen.

Probably not a fit

Patients with prior H. pylori infection or those not undergoing biopsy/surgical specimens may not benefit from the findings.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study collects biopsy specimens from patients with functional dyspepsia, chronic gastritis, non-H. pylori atrophic gastritis with intestinal metaplasia or dysplasia, and gastric cancer, plus bariatric patients as controls. It aims to determine how often non-H. pylori Helicobacter species appear in these conditions. The analysis will use routinely obtained biopsy material to identify and characterize the bacteria's presence. The study is prospective and multicenter, leveraging specimens from multiple collaborating institutions. No interventions are described beyond specimen analysis.

Why it matters

Potential benefit: If non-H. pylori Helicobacter species are common, it could guide future diagnostics and targeted research for gastric diseases.

How similar studies have gone: Previous studies have investigated non-H. pylori Helicobacter species in gastric disease with varying prevalence, making this study's focused, prospective design informative.
