[Relation between Helicobacter pylori and atopic diseases].

The rise in the incidence of atopic diseases in the last years is associated to a greater prevalence of viral and bacterial infections. The infections facilitate a chronic inflammatory process that is directly related to the sensibilization of mast cells which favors manifestations of allergic diseases. Within the proposed bacteriological agents as causes of is Helicobacter pylori. This work is a bibliographical revision and concludes that there is not evidence of the direct causal relation between infection by Helicobacter and allergic diseases; however, it can play an indirect role. Controlled and randomized studies are necessary to know accurately this relation because the eradication treatment could be a real alternative in these patients handling.
