Vascular and immunological disorders associated with Helicobacter pylori infection.
Helicobacter pylori, the main aetiological factor for gastritis and peptic ulcer has been associated with some extradigestive diseases. In particular, vascular disorders, such as ischaemic heart disease, primary Raynaud phenomenon and headache appear to be related to the presence of the bacterium. Moreover, some autoimmune diseases, such as Henoch-Schonlein purpura, Sjögren syndrome and others have been shown to have a link with Helicobacter pylori infection Probably, in subjects with a particular predisposition, the release of substances with a vasoactive and proinflammatory activity, which is determined by Helicobacter pylori infection, may influence some extradigestive districts.
