ABSTRACT
BACKGROUND:
Helicobacter pylori (H. pylori) is strongly associated with peptic ulcer disease and gastric cancer. We evaluated two triple therapy regimens comprising esomeprazole, high dose bismuth, and different doses of amoxicillin for first-line H. pylori eradication. MATERIALS ANDMETHODS:
Two hundred patients with dyspepsia and naive H. pylori infection were randomly assigned into two groups (n = 100). Both groups were treated for 14 days similarly with esomeprazole (40 mg, twice daily) and bismuth subcitrate (240 mg, three times daily), but the dose of amoxicillin was varied between Groups A (750 mg) and B (1000 mg) three times daily. Treatment compliance and side effect were evaluated following the therapies and after 8 weeks, a negative test of stool H. pylori antigen confirmed eradication.RESULTS:
The two groups were comparable with respect to sex and age. According to intention to treat analysis, eradication rates were 80% (95% CI 77.2%-82.8%) and 90% (95% CI 84.1%-95.9%) in A and B groups, respectively (p = 0.22). Per-protocol eradication rates were 87% (95% CI 80.4%-93.6%) and 92.8% (95% CI 87.7%-97.9%), respectively (p = 0.23). Severe adverse effects were 3% and 2%, respectively (p = 0.34).CONCLUSION:
High dose esomeprazole, amoxicillin and bismuth achieved 92.8% cure rates per protocol in a country with a high background rate of resistance. Additional studies are needed to ascertain whether this therapy can be further improved. Until then, it can be recommended as a first-line H. pylori eradication in north of Iran.Palavras-chave
