Factors Associated with Treatment Failure of Helicobacter pylori Eradication / 胃肠病学

ABSTRACT

Helicobacter pylori(Hp)infection is associated with many kinds of upper gastrointestinal diseases,and is also associated with some extragastric diseases. Hp eradication can cure peptic ulcer or reduce the risk of recurrence, inhibit the development of chronic atrophic gastritis,and decrease the risk of gastric carcinoma. Antibiotic resistance is the main cause of treatment failure of Hp eradication. Other factors,such as host,environment,co-existing diseases,and treatment regimens may also affect the results of Hp eradication.
