Summary

Helicobacter pylori eradication can reduce the risk of gastric cancer and decrease the recurrence of ulcers. However, in recent years, the increasing antibiotic resistance of Helicobacter pylori has reduced the efficacy of clarithromycin-based triple therapy to below 80%. The recent studies, including real-world data and a clinical trial, have consistently found that females have poorer eradication rate of Helicobacter pylori as compared with males. In previous clinical trial, investigators discovered that the efficacy of a 10-day bismuth quadruple therapy was not inferior to a 14-day bismuth quadruple therapy. However, it remains to be investigated whether the 10-day bismuth quadruple therapy is still non-inferior to the 14-day regimen in females. This project continues the clinical trial to investigate whether the efficacy of the 10-day bismuth quadruple therapy in females is inferior to that in males and whether the 14-day bismuth quadruple therapy is superior to the 10-day regimen in females. The ultimate goal is to establish that male patients can use the 10-day bismuth quadruple therapy with fewer side effects and without compromising efficacy as compared with the 14-day regimen; while female patients are recommended to use the 14-day bismuth quadruple therapy as it would be more effective than the 10-day regimen. Considering sex in research is becoming increasingly important, as females have more antibiotic-resistant Helicobacter pylori infection than males. The bismuth quadruple therapy can overcome most resistance issues. Researching and comparing the difference in the efficacy of bismuth quadruple therapy for Helicobacter pylori eradication between females and males are of significant clinical importance and align with current research trends.
