Summary
Helicobacter pylori (H.P.) infection is common in gastric and duodenal ulcers. While antimicrobial therapy can help, H.P. often returns, but its eradication improves stomach inflammation.
Area of Science:
- Gastroenterology
- Microbiology
- Internal Medicine
Background:
- Helicobacter pylori (H.P.) is a significant pathogen implicated in various gastroduodenal diseases.
- Understanding H.P. prevalence and its impact on ulcer healing and inflammation is crucial for effective management.
Purpose of the Study:
- To investigate the prevalence of H.P. infection in patients with gastroduodenal diseases.
- To assess the efficacy of short-term antimicrobial therapy and its long-term impact on H.P. recurrence and gastric inflammation.
Main Methods:
- Prevalence of H.P. infection determined in gastric and duodenal ulcer patients.
- Assessment of H.P. presence during ulcer healing and one year post-treatment.
- Evaluation of short-term antimicrobial therapy efficacy (cefixim, ofloxacin, bismuth subnitrate).
- Histological analysis of antral mucosa inflammation in H.P. positive and negative patients.
Main Results:
- H.P. positivity rates were 67.6% in gastric ulcer and 82.2% in duodenal ulcer patients.
- H.P. was frequently detected during ulcer healing and recurred in a significant number of patients one year after treatment.
- Antimicrobial therapy achieved a 50% success rate in H.P. positive patients.
- Histological inflammation was more pronounced in H.P. positive patients, and H.P. eradication improved this inflammation.
Conclusions:
- H.P. infection is highly prevalent in gastroduodenal ulcers and frequently persists despite short-term therapy.
- Eradication of H.P. positively impacts gastric mucosal inflammation, regardless of other medications used.
