Smoking and Drinking Did Not Increase the Failure of Therapeutic Helicobacter pylori Eradication by Vonoprazan, Clarithromycin, and Amoxicillin.

AIMS

The influence of lifestyle-related factors, including smoking and drinking, was evaluated for Helicobacter pylori eradication therapy with vonoprazan or proton pump inhibitors (PPIs).

METHODS

Between 2012 and 2016, the medical records of 620 patients receiving H. pylori eradication therapy at Saiseikai Karatsu Hospital were evaluated. Patients had received vonoprazan (20 mg) or PPIs with 200 mg clarithromycin and 750 mg amoxicillin twice daily for 7 days. The influence of lifestyle-related factors on eradication failure was determined in the 2 groups.

RESULTS

The eradication rates for vonoprazan and lansoprazole, rabeprazole, and esomeprazole were, respectively, 91.0, 73.8, 72.0, and 84.6%. The vonoprazan eradication rate was significantly higher than those for the PPIs (p < 0.01). Habitual smoking and drinking did not increase eradication failure, and smoking and drinking during the eradication period did not reduce the eradication rate. Metabolic syndrome-related factors including obesity, hypertension, and diabetes mellitus had no negative influence on the eradication rate. Eradication with vonoprazan was more effective compared with that achieved through the use of PPIs.

CONCLUSION

Lifestyle-related factors including smoking and drinking did not exacerbate the H. pylori eradication failure, and vonoprazan was more effective than the PPIs.
