Helicobacter Pylori Antibiotic Susceptibility Testing of Korea

Helicobacter Pylori Antibiotic Susceptibility Testing of Korea

The purpose of this study is to make nationwide registry for antimicrobial resistance of Helicobacter pylori using single method with agar dilution in Korea.

Backgrounds:

The success rate of Helicobacter pylori eradication in Korea is not sufficient in recent days. The main cause of eradication failure is known as antimicrobial resistance and previous studies showed that resistant rates were different according to the regions in Korea. However, until now, there are not enough studies about the nationwide results for antimicrobial resistance and previous reports used various methods for the resistant test.

Theories and Plans:

The nationwide resistant registry of Helicobacter pylori using standardized single method, agar dilution test, can be useful for the development of new eradication methods to make eradication rate higher. Moreover, the higher rate of Helicobacter pylori eradication can reduce the chance of gastric cancer and also can reduce the medical expenses.

Inclusion Criteria:

• Aged 19 to 79 year person who need the examination of Helicobacter pylori infection during upper gastrointestinal endoscopy.
• No history of Helicobacter pylori eradication.
• No history of antibiotics within one month.
• Person who agree on the consent.

Exclusion Criteria:

• History of antibiotics more than 3 days sequentially within one month.
• History of subtotal gastrectomy.
• Person who does not agree on the consent.
