Helicobacter pylori eradication and histopathological esophagitis in dyspeptic patients.

Background: The association of Helicobacter pylori with peptic ulcer disease, atrophic gastritis, gastric adenocarcinoma, MALT (mucosa associated lymphoid tissue) lymphoma is well recognized. Aim: This study was conducted to see whether there was any relation between H pylori eradication and reflux esophagitis in Iran. Methods: Eligible dyspeptic patients referred to Gastroenterology clinic in Baqiyatollah hospital were endoscopied and evaluated for endoscopic and pathologic esophagitis and the H. pylori infection status was determined by rapid urease test. H. pylori infection was treated by an anti H. pylori drug regimen and successfully eradicated patients according to negative C14 urea breath test were followed and re-endoscopy was performed 6-9 months after the end of treatment. Results: From175 eligible patients,54% were H. pylori positive, 68 of them (72%) had successful H.P. eradication and 64 patients completed the follow-up. The rate of histopathologic inflammatory esophagitis was higher in second endoscopy, compared with that of first endoscopy, i.e., before H. pylori eradication (75% vs 40.6%) (p<0.05). Progression of pathological esophagitis was seen in 56.3% of patients between the two endoscopic evaluations in spite of no change in clinical and endoscopic findings. There were no significant differences in dietary and smoking habits and body weights on re-endoscopy session compared with that of the first endoscopy visit (p>0.05). Conclusion: This study suggests that H.pylori eradication in dyspeptic patients may lead to increased frequency of histopathological esophagitis Hence, In patients presenting with symptoms of dyspepsia , a cautious approach should be exercised if H.pylori eradication is being contemplated.
