[Immune thrombocytopenia: current diagnostics and therapy : The new 2023 expert report in brief].

Immune thrombocytopenia (ITP) is an acquired thrombocytopenia caused by an autoimmune reaction against platelets in the blood and against megakaryocytes in the bone marrow. The indication for treatment is based on the bleeding symptoms and patient-specific factors. This article presents the current 2023 expert report that also forms the basis for the updated version of the Onkopedia guideline, which is expected in the course of 2024. In addition to the background to pathogenesis and pathophysiology, the article discusses clinical manifestations and diagnostics, as well as first-, second- and third-line therapy, including the management of emergency situations. Practice-relevant recommendations are given on the use and side effects of glucocorticoids, as well as on therapy with thrombopoietin receptor agonists (TRA), including the withdrawal regimen, and on treatment with a syk inhibitor.
