Primary Immune Thrombocytopenia (TIP) is an autoimmune disease that accelerates the peripheral destruction of platelets and alters megakaryocytopoiesis. Helicobacter pylori infection and eradication has been associated with an increase in the platelet count in patients with IPT. The aim of this article is to evaluate the platelet response after H. pylori eradication in patients with chronic splenectomized IPT Between 2008 and 2009, adult patients with a diagnosis of chronic IPT, splenectomized; They were given breath test with carbon 13-labeled urea (PAU13C). Patients who tested positive received eradication treatment with amoxicillin, omeprazole and clarithromycin for 14 days. After 6 weeks of treatment, a second PAU13C was performed. Baseline platelet counts were performed and every six months until the completion of two years. 40 patients, 34 women and 6 men were included, PAU13C was positive in 17 patients (42.5%). H. pylori eradication was obtained in 16 patients (94%) confirmed by post-treatment PAU13C. In the follow-up of the patients it was observed that there was increase of platelets in 7 of the patients with eradication of H. pylori, while of the patients not infected in 9 also an increase of platelets was observed. There were no differences in the increase in platelet count among patients positive or negative to the H. pylori breath test at followup at 24 months.
