Helicobacter pylori (H.pylori)
infection is the most important pathogenic microorganisms associated with the development of chronic
gastritis,
peptic ulcer and
gastric mucosa-associated
lymphoid tissue lymphoma (MALT) in
children. H.pylori
infection may occur in early childhood and last a lifetime even directly affecting the
health of adulthood unlessH.pylori
infection was eradicated. This article aims to
review the
infection condition,
infection pathway and immunological characteristics ofH.pylori and its relationship with extragastroduodenal
diseases in
children.
