Abstract

It is well known that Helicobacter pylori infection is associated with gastroduodenal diseases such as gastritis, peptic ulcer diseases, gastric adenocarcinoma, and mucosa-associated lymphoid tissue lymphoma (MALToma). Furthermore, various extra-gastroduodenal diseases have been suggested to be related with H. pylori infection. Although the exact pathophysiologic mechanisms have not been established yet, it is plausible that certain inflammatory and immune reactions triggered by H. pylori infection might play a role. In this review, I summarized the articles which dealt with H. pylori infection and extra-gastroduodenal diseases along with their pathophysiologic mechanisms.

Key Words: Helicobacter pylori; Extra-gastroduodenal disease
