Extragastric manifestations of Helicobacter pylori infection

Abstract

In the previous year, some extragastric diseases, possibly linked to Helicobacter pylori infection, have been largely investigated. There are, in fact, several studies concerning cardiovascular diseases, lung diseases, hematologic diseases, eye and skin diseases, hepatobiliary diseases, diabetes mellitus, and neurological disorders. Among them, the relationship between bacterial CagA positivity and coronary heart disease is reportedly emphasized. Concerning normal tension glaucoma, new interesting data are playing in favor of the association with H. pylori infection. For other diseases, there are many interesting results, although more studies are needed to clarify the reality of the proposed association.
