    Abstract:
    AIM: To evaluate the association of pre-treatment Helicobacter pylori (H. pylori) density with bacterial eradication and ulcer healing rates in patients with active duodenal ulcer. METHODS: One hundred and four consecutive duodenal ulcer outpatients with H. pylori infection ascertained by gastric histopathology and (13)C-urea breath test (UBT) were enrolled in this study. H. pylori density was graded histologically according to the Sydney system (normal, mild, moderate, and marked). In each patient, lansoprazole (30 mg b.i.d.), clarithromycin (500 mg b.i.d.) and amoxicillin (1 g b.i.d.) were used for 1 week, then 30 mg lansoprazole once daily was continued for an additional 3 weeks. Follow-up endoscopy was performed at 4 weeks after completion of the therapy, and UBT was done at 4 and 8 weeks after completion of the therapy. RESULTS: The H. pylori eradication rates were 88.9 %/100.0 %, 94.3 %/100.0 %, and 69.7 %/85.2 %; and the ulcer healing rates were 88.9 %/100.0 %, 94.3 %/100.0 %, and 63.6 %/77.8 % (intention-to-treat/per protocol analysis) in the mild, moderate, and marked H. pylori density groups, respectively. The association of pretreatment H. pylori density with the eradication rate and ulcer healing rate was both statistically significant (P=0.013/0.006 and 0.002/<0.001, respectively; using results of intention-to-treat/per protocol analysis). CONCLUSION: Intragastric bacterial load may affect both the outcome of eradication treatment and ulcer healing in patients with active duodenal ulcer disease.
