    BACKGROUND: Distribution and nature of gastritis are major determinants of clinical outcome of H. pylori infection. The gastric inflammatory changes associated with this infection in developing countries have not been systematically studied. AIMS: To evaluate the inflammatory changes in gastric antrum and corpus in patients with duodenal ulcer and H. pylori infection, before and after H. pylori eradication therapy. METHODS: Histology and H. pylori density were studied in gastric biopsies obtained from 53 consecutive patients with active duodenal ulcer and H. pylori infection. Biopsies were obtained before and 4 weeks after H. pylori eradication therapy, from the anterior and posterior walls of the antrum and corpus, and were evaluated according to the Sydney system. RESULTS: In the pre-H. py/ori eradication antral biopsies, chronic gastritis, active gastritis, atrophy, intestinal metaplasia (IM) and lymphoid follicles / aggregates were seen in 53 (100%), 49 (92%), 11 (21%), 7 (13%) and 28 (53%) patients, respectively. In the corresponding biopsies from gastric corpus, these changes were seen in 49 (92%), 23 (43%), 2 (4%), 2 (4%) and 8 (15%), respectively. All changes except IM were significantly more frequent and of higher grade in the antrum. The grade of chronic gastritis was significantly higher in antrum than corpus; the frequency of gastritis in the antrum and corpus was similar (100% vs. 92%). H. pylori density was also higher in the antrum and correlated well with the grades of chronic gastritis and activity at both sites. Eradication of H. pylori was achieved in 39 patients (74%), and led to significant decrease in gastritis; no change was seen in patients who did not eradicate the organism. CONCLUSIONS: Antral-predominant chronic gastritis and activity are present in more than 90% of patients with H. pylori infection associated with duodenal ulcer, and the grade of gastritis correlates with the density of the organism. Eradication therapy results in improvement of both chronic gastritis and activity.

    Randomized trial of a quadruple-drug regimen and a triple-drug regimen for eradication of Helicobacter pylori: long-term follow-up study.
    (2001-09-26) Kumar, D; Ahuja, V; Dhar, A; Sharma, M P
    BACKGROUND: In developing countries, H. pylori eradication rates are suboptimal. A quadruple-drug regimen may improve on the eradication rate achieved with triple-drug regimen. METHODS: 64 consecutive patients with active duodenal ulcer associated with H. pylori infection were randomized to receive either a one-week triple-drug regimen (lansoprazole, clarithromycin, secnidazole) or a one-week quadruple-drug regimen (lansoprazole, amoxycillin, colloidal bismuth subcitrate, secnidazole). H. pylori eradication and ulcer healing were assessed 4 weeks after completion of therapy. Patients were followed up at 24 weeks and 52 weeks for H. pylori recurrence. RESULTS: Both the regimens eradicated H. pylori in 75% (95% CI 0.6-0.9) of patients. The ulcer-healing rate with the triple-drug regimen was 97% (95% CI 0.91-1.0) and 91% (95% CI 0.91-1.0) with the quadruple-drug regimen. No ulcer or H. pylori recurrence occurred in patients eradicated with the triple-drug regimen, whereas 8.3% of patients eradicated with the quadruple-drug regimen had ulcer as well as H. pylori recurrence during the 52-week follow up. CONCLUSION: Triple-drug regimen achieves similar eradication rates as quadruple-drug regimen in H. pylori infection.
