About this trial

Helicobacter pylori (H. pylori) infection, affecting an estimated 50% of the global population, is a main cause of chronic gastritis, peptic ulcers and gastric cancer. By causing progressive damage to the stomach and may eventually result in gastric atrophy, H. pylori infection has been demonstrated to be responsible for more than 95% of gastric malignancies

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Patients with H. pylori infection;

Aged 18-65 years.

Disqualifiers

Patients with gastrectomy, acute GI bleeding and advanced gastric cancer;

Conditions unsuitable for performance of gastroscopy, such as coagulopathy, impaired renal function;

Pregnancy or breastfeeding;

Inability to provide informed consent and other situations that could interfere with the examination or therapeutic protocol.

Trial design

Design model

Single group

Treatments tested in this trial

  • biopsy

    Device

    patients enrolled in the study will receive gastroscopy and biopsies in order to evaluate status of pathology.

  • H. pylori eradication

    Drug

    H. pylori eradication therapy comprising esomeprazole, amoxicillin,clarithromycin and colloidal bismuth pectin. If failed in eradicating H. pylori, a culture based antimicrobial susceptibility test will be used to guide H. pylori eradication.
