• 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 immuneTP.~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 The recent entry of Helicobacter pylori to the growing list of etiologies of itp has stirred much interest. . The relationship between H pylori infection and immune thrombocytopenia (ITP) is less clear .~However, among patients with H.pylori-associated ITP, a significant percentage achieve lasting remission after eradication of H.pylori .~H.pylori can be readily detected by non invasive methods, the C-urea breath test and antigen detection in stools are considered to be the most accurate, with both sensitivity and specificity in the range of 90% to 95% .
