Abstract
AIM
To evaluate the clinical efficacy and safety of high-dose amoxicillin/esomeprazole dual therapy as a first-line therapy for Helicobacter pylori (H. pylori) eradication.
METHODS
One hundred and forty-two subjects infected with H. pylori and naive to treatment were randomly assigned to receive either 14-d high-dose amoxicillin/esomeprazole dual therapy (esomeprazole 20 mg and amoxicillin 0.75 g, four times a day; EA group) or bismuth-based quadruple therapy [esomeprazole 20 mg, bismuth potassium citrate 220 mg (elemental bismuth), amoxicillin 1 g, and clarithromycin 0.5 g, twice a day; EBAC group]. Six weeks after treatment, H. pylori eradication was assessed by using the urea breath test (13C or 14C).
RESULTS
A total of 131 subjects completed this clinical trial. H. pylori eradication rates by intention-to-treat (ITT) and per-protocol (PP) analysis in the EA group were 82.9% and 89.2%, respectively, and those in the EBAC group were 86.1% and 93.9%, respectively. No significant difference was found in H. pylori eradication rates by both ITT and PP analysis (P > 0.05). The incidence of side effects by PP analysis in the EBAC group was significantly higher than that in the EA group (15.2% vs 3.1%, P < 0.05). All the side effects disappeared after discontinuing the drugs.
CONCLUSION
High-dose amoxicillin/esomeprazole dual therapy can be used as an effective and safety first-line therapy for H. pylori infection.
