Guidelines in the management of Helicobacter pylori infection in Japan
1Department of Gastroenterology, Hokkaido University Graduate School of Medicine, Sapporo, Japan.
Insights
Guidelines for diagnosing and treating Helicobacter pylori infection are established for Japanese physicians. Recommended therapies include a 1-week course of lansoprazole, amoxicillin, and clarithromycin for ulcer patients.
Area of Science:
- Gastroenterology
- Infectious Diseases
- Clinical Practice Guidelines
Background:
- The Japanese Society for Helicobacter Research developed guidelines for H. pylori diagnosis and treatment.
- Preparation aligns with the anticipated national health system coverage for H. pylori therapy.
Purpose of the Study:
- To provide physicians with practical guidelines for managing H. pylori infections.
- To standardize the approach to H. pylori diagnosis and eradication therapy.
Main Methods:
- A committee formed and convened six meetings.
- A consensus meeting in Kobe included general practitioners and international experts.
- Guidelines were developed based on expert opinion and current evidence.
Main Results:
- H. pylori eradication therapy is recommended for gastric/duodenal ulcers and MALT lymphoma (at specialist centers).
- Efficacy is under evaluation for hyperplastic polyps, chronic atrophic gastritis, non-ulcer dyspepsia, and post-resection/gastrectomy patients.
- Diagnosis requires at least one endoscopic biopsy test and one non-biopsy test; multiple tests are advised for accuracy.
- First-line treatment in Japan: lansoprazole, amoxicillin, and clarithromycin for 1 week.
Conclusions:
- These guidelines are designed for implementation in routine medical practice.
- Their utilization is planned following national health system coverage for H. pylori infection management.
Background:
In preparation of the approval of Helicobacter pylori therapy by the Japanese national health system, the board of directors of the Japanese Society for Helicobacter Research decided to prepare guidelines on the diagnosis and treatment of H. pylori infection for physicians in routine medical practice.
Methods:
A guidelines preparation committee was formed and six meetings were held. Then, in December 1999, a consensus meeting was held in Kobe to obtain the opinions of general practitioners as well as experts from Europe, North America, and Asia.
Results:
Helicobacter pylori eradication therapy is recommended in gastric or duodenal ulcer patients. Helicobacter pylori eradication therapy is recommended or gastric mucosa associated lymphoid tissue (MALT) lymphoma but it should be done at specialist institutions. The significance of H. pylori eradication therapy is still under evaluation in patients with hyperplastic polyps, chronic atrophic gastritis, non-ulcer dyspepsia and in patients after endoscopic mucosal resection of gastric cancer and after gastrectomy for gastric cancer. When diagnosing H. pylori infection, at least one of the tests requiring endoscopic biopsy (e.g. rapid urease test, histology, or culture) and tests not requiring biopsy (e.g. measurement of H. pylori antibody or urea breath test) should be used. Multiple tests are recommended to increase the accuracy. The drugs of first choice currently covered by the national health insurance system in Japan are: lansoprazole (30 mg) 1 capsule twice daily, amoxicillin (250 mg) 3 capsules twice daily, and clarithromycin (200 mg) 1-2 tablets twice daily. These three drugs should be administered after breakfast and dinner for 1 week.
Conclusion:
These guidelines are intended for utilization in routine medical practice after the Japanese national health system begins to cover the management of H. pylori infection.

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
