title: [Helicobacter pylori infection: from gastric to systemic disease].
abstract: H. pylori infection, through a chronic stimulation of the immune system and the occurrence of molecular mimicry mechanisms, is responsible for the majority of the gastroduodenal diseases and also for some extragastric disorders, including sideropenic anemia and idiopathic thrombocytopenic purpura; other diseases are under investigation.
