Immune Thrombocytopenic Purpura and Helicobacter pylori Infection

We read with great interest the article by Michel et al¹ on a possible association between Helicobacter pylori infection and autoimmune thrombocytopenic purpura (AITP) in adults. The authors found no cross-reactivity between platelet and H pylori antibodies and, on this basis, they excluded the evidence of an association between bacterial infection and AITP.
