Abstract
BACKGROUND: Helicobacter pylori (H pylori) can cause gastritis, peptic ulcers, gastric cancer, and many other gastrointestinal diseases. The 14-day neo-dual therapy for H pylori is considered by most countries to have good eradication rates, while the 7- and 10-day studies have been more widely explored, however, we find that their results are different. The applicability of the shorter and less expensive 10-day neo-dual therapy to our country has not yet been confirmed. METHODS: The patients were divided into 3 groups of 200 each by randomization method. Group A: patients received vonoprazan 20 mg, bid + amoxicillin(1 g), tid, for 14 days. Group B: vonoprazan (20 mg) bid + amoxicillin (1 g) tid, duration of treatment is 10 days, group C: rabeprazole (20 mg) bid + bismuth potassium citrate tablets/tinidazole tablets/clarithromycin tablets, combined package (4.2 g), bid, duration of treatment 14 days. The main comparisons were H pylori eradication rate, adverse drug reaction profile and cost-effect ratio in each group. RESULTS: The eradication rates of groups A, B, and C were 92.5%, 91.6%, and 80.1%, respectively. There was no significant difference in the eradication rates of groups A and B (P > .05), groups A and B had statistically significantly better eradication rates than group C (P < .05). The incidence of adverse reactions in groups A, B, and C was 9.5%, 8.5%, and 17.0%, respectively. There was no difference in the incidence of adverse reactions between A and B: (P > .05), The incidence of adverse reactions was statistically significantly lower in groups A and B than in group C (P < .05). Logistic regression analysis showed nonsmokers had a higher eradication rate (OR 2.587, 95% CI: 1.377-4.859, P = .003), and taller patients were more likely to have successful eradication (OR 1.052, 95% CI: 1.008-1.097, P = .020). Group B had the lowest cost-benefit analysis results. CONCLUSION: Group B had an acceptable eradication rate, the lowest incidence of adverse effects, and the lowest cost analysis. Eradication is more likely to be successful in patients who do not smoke and in those who are taller.
