Helicobacter pylori infection may protect against gastroesophageal reflux disease (GERD) in Japan. Eradicating H. pylori might increase GERD prevalence, unlike in Western countries, due to improved mucosal atrophy.

Area of Science:

  • Gastroenterology
  • Epidemiology
  • Microbiology

Background:

  • Prevalence of GERD is lower in Japan than in Western countries.
  • H. pylori infection is present in 30-40% of Japanese GERD patients, suggesting a protective role.
  • Pathophysiology of GERD differs significantly between Western and Japanese populations.

Purpose of the Study:

  • To investigate the role of H. pylori in GERD development in Japan.
  • To explore the potential impact of H. pylori eradication on GERD prevalence in Japan.
  • To address diagnostic challenges in Non-erosive GERD (NERD).

Main Methods:

  • Comparative analysis of GERD prevalence and H. pylori infection rates in Japan versus Western countries.
  • Review of existing literature on H. pylori eradication and its effects on GERD.

  • Evaluation of diagnostic accuracy for NERD.

    • Main Results:

    • H. pylori infection appears to have a protective effect against GERD in Japan.
    • Eradication of H. pylori may lead to an increase in GERD cases in Japan.
    • Proton pump inhibitor (PPI) efficacy for NERD is approximately 60%, indicating potential misdiagnosis.

    Conclusions:

    • H. pylori infection plays a distinct role in GERD pathophysiology in Japan compared to the West.
    • H. pylori eradication strategies in Japan require careful consideration due to potential GERD increase.
    • Improved diagnostic methods are needed to accurately identify NERD patients.
