What this trial studies

This observational study aims to evaluate the prevalence and trends of antimicrobial resistance in Helicobacter pylori isolated from patients with upper gastrointestinal diseases over a long-term period. By analyzing H. pylori cultures collected since 2003, the study will investigate minimal inhibitory concentrations and resistance rates to various antibiotics. It will also explore risk factors associated with antibiotic resistance and the implications for treatment failure. The findings are expected to inform future eradication strategies for H. pylori infections.

Who should consider this trial

Good fit: Ideal candidates for this study are patients diagnosed with Helicobacter pylori infection who consent to undergo culture analysis via endoscopic resection.

Not a fit: Patients with concurrent critical illnesses, those who have recently taken antibiotics or certain medications, and pregnant or nursing individuals may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment strategies for Helicobacter pylori infections, enhancing eradication rates and patient outcomes.

How similar studies have performed: While there may be studies on antimicrobial resistance in H. pylori, this specific long-term trend analysis appears to be novel and untested.

Eligibility criteria

Exclusion Criteria:

* Patients with a concurrent critical illness, who abused drugs or alcohol, who were pregnant or nursing, or those who had received antibiotics, PPIs, or bismuth salts within 4 weeks, were excluded.
