Helicobacter pylori eradication: novel therapy for immune thrombocytopenic purpura? A review of the literature. Export

@article{citeulike:127070, abstract = {Eradication of Helicobacter pylori (H. pylori ) from the gastric mucosa has been associated with improvement of several systemic diseases, including immune thrombocytopenic purpura (ITP).

Review of published studies in which eradication of H. pylori has been performed in the ITP population indicates an overall response rate of 52\% in 193 subjects in whom H. pylori was eradicated. Cohorts from Japan and Italy report higher response rates.

Several theories including molecular mimicry, platelet aggregation, and immunomodulatory effects of macrolides have been proposed to explain the platelet response to anti-H. pylori therapy.
