The Effect and Frequency of Helicobacter Pylori Infection in Primary Immune Thrombocytopenic Patients

Immune thrombocytopenia (ITP) is an autoimmune disorder characterized by low platelet count (i.e less than 100.000) . In ITP, platelet surface membrane proteins become antigenic for unknown reasons , leading to stimulation of the immune system , autoantibody production, and platelet destruction In recent years ,the list of etiologies of ITP has been steadily increasing, so the term "idiopathic" is becoming obsolete, increasingly replaced by "immune"TP . Treatment of ITP may be conceptually divided into rescue therapy and maintenance therapy . the terminology of corticosteroid-dependence means The need for ongoing or repeated doses administration of corticosteroids for at least 2 months to maintain a platelet count at or above 30 \_ 109/L and/or to avoid bleeding. So, patients with corticosteroid dependence are considered non responders
