Abstract

This study was a before and after clinical evaluation of Helicobacter pylori eradication on platelet counts in a group of 23 patients with chronic Idiopathic (Autoimmune) thrombocytopenic purpura (CITP). H. pylori infection was identified in patients by a ¹³C-urea breath test and confirmed by an H. pylori stool antigen test. Eradication was conducted in patients testing positive. Infected (n = 10) and uninfected (n = 13) patient groups did not differ with respect to age, gender, history of previous splenectomy, treatment with anti-D, current treatment with corticosteroids, or initial platelet counts. H pylori eradication was successful in eight infected CITP patients, with two patients not responsive to treatment. Compared to the uninfected group, patients in the infected group who responded to eradication therapy had significantly increased platelet counts after six months (56.2 ± 22.2 vs. 233 ± 85.6 ×10³ million cells/L; P < 0.01), whereas platelet counts in the non-responding patients and uninfected group did not differ after this period of time. H. pylori eradication promotes significant platelet count improvement in patients with CITP. Thus, all patients with CITP should be tested and treated for H. pylori infections.
