Background: Idiopathic thrombocytopenic purpura is an autoimmune blood disorder in which platelet destruction is mediated by anti-platelet antibodies. There are two forms of ITP: acute and chronic. The aim of the present study was to evaluate the clinical variables in adult patients with acute ITP in west of Iran.
Patients and Methods: Medical records of adult patients with diagnosis of acute ITP referring to Hematology Clinic of Kermanshah from year 2004-2014 were analyzed. Demographic and hematologic data and status of H pylori infection of the patients were extracted.
Results: There were records of fifty-three patients diagnosed with acute ITP. Mean age at diagnosis was 39.1 years (±13.3) ranging from 14-68 years. Twenty patients (37.7%) were male. Out of 53 patients, 25 cases (47.2%) were positive for H pylori infection. There was significant association between Hb and platelet with sex of the patients (P&le0.05).
Conclusions: Mean age of adult patients with acute ITP was more than figures expected in chronic ITP patients.  In addition, Prevalence of H pylori infection in acute ITP patients was more than chronic ITP patients.
