[Diagnosis and Therapy of Immune thrombocytopenia].

Immune thrombocytopenia (ITP) is a heterogeneous disease. Diagnosis of primary ITP continues to be based on the exclusion of all known causes for secondary ITP. The new ITP classification distinguishes three categories. First line treatment consists of either dexamethasone or prednisone. The most effective options in second line treatment are splenectomy or thrombopoietin receptor agonists. The medical societies for hematology and oncology of the German-speaking countries have recently updated their guidelines on ITP.
