Platelet count response to Helicobacter pylori eradication for idiopathic thrombocytopenic purpura in northeastern Brazil

H. pylori eradication therapy showed relatively low platelet recovery rates, comparable with previous studies from southeastern Brazil. The effect of H. pylori eradication on platelet counts remained after one year of follow-up suggesting that treating H. pylori infection might be worthwhile in a subset of chronic idiopathic thrombocytopenic purpura patients.
