Erosive duodenitis: prevalence of Helicobacter pylori infection and response to eradication therapy with omeprazole plus two antibiotics.

AbstractOBJECTIVES:
To study the prevalence of Helicobacter pylori infection in patients with erosive duodenitis (ED), the associated gastric histological lesions and their response to eradication therapy with omeprazole plus two antibiotics.
METHODS:
A prospective study was made of 57 patients with ED (mean age 46 +/- 16 years, 72% males). At endoscopy, biopsies from gastric antrum and body were obtained for histological study (haematoxylin and eosin). A 13C-urea breath test was also performed. Omeprazole 20 mg twice daily plus two antibiotics (amoxycillin 1 g twice daily, clarithromycin 500 mg twice daily, metronidazole 500 mg twice daily) were administered for 1 week. Endoscopy and breath test were repeated 1 month after completing therapy, and the breath test was performed again at 6 months.
RESULTS:
All patients were H. pylori positive. Overall eradication was achieved in 86% (95% CI 75-93%). Duodenal erosion healing was obtained in 45 patients (79%). Healing was achieved in 86% (CI 73-93%) of cases with successful eradication therapy, but only in 3/8 (37%; CI 8.5-75%) patients with therapy failure (P < 0.01). In the multivariate analysis, H. pylori eradication was the only variable which correlated with erosion healing (odds ratio 10; CI 2-51; P < 0.01). Histological improvement, in both the gastric antrum and body, was demonstrated when eradication was achieved (P < 0.001). Six months after diagnosis H. pylori absence was confirmed in all patients with initial therapy success (all of them asymptomatic), and infection was confirmed in the eight patients who were H. pylori positive after therapy (six of them symptomatic). At 6-month follow-up, endoscopy was normal in 6/7 H. pylori-negative patients with previously persistent ED, while erosions were still present in 4/5 H. pylori-positive patients with previously persistent ED.
CONCLUSION:
A high prevalence (100%) of H. pylori infection in patients with ED was observed. A 1-week twice daily therapy with omeprazole plus two antibiotics (clarithromycin plus amoxycillin or metronidazole) was very effective in H. pylori eradication, duodenal erosion healing, symptomatic improvement, and in disappearance of associated histological gastritis. These observations suggest that ED should be considered a variant form of duodenal ulcer disease and treated accordingly; that is, with H. pylori eradication therapy.
