Utility of Thrombopoietin Receptor Agonists (TPO-RAs) for Prolonged Thrombocytopenia After CAR-T Cell Therapy.

The University of Chicago Medical Center, Chicago IL.
Background: Chimeric Antigen Receptor T-cell (CAR-T) therapy has revolutionized the treatment landscape for various hematological malignancies. However, it is associated with a range of hematologic complications, including severe and often prolonged thrombocytopenia. Currently, there are no known effective preventative or management measures against CAR-T-induced thrombocytopenia.

Immune thrombocytopenia (ITP) in pediatric patients is a common cause of isolated thrombocytopenia. Various pathophysiological mechanisms are implicated in ITP pathogenesis, including the production of autoantibodies against components of platelets (PLTs) by B-cells, the activation of the complement system, phagocytosis by macrophages mediated by Fcγ receptors, the dysregulation of T cells, and reduced bone marrow megakaryopoiesis. ITP is commonly manifested with skin and mucosal bleeding, and it is a diagnosis of exclusion.

Background: There is no standard treatment to accelerate recovery from melphalan-induced thrombocytopenia in multiple myeloma (MM) patients undergoing autologous stem cell transplantation (ASCT). Romiplostim, a thrombopoietin receptor agonist, has been developed to upregulate platelet production.
Objective: This study aimed to assess the efficacy and safety of romiplostim in reducing platelet transfusions post-ASCT in MM patients.
A Case of Eltrombopag-Induced Thrombotic Microangiopathy Initiating Hemodialysis.

Thrombopoietin receptor agonists are used in addition to steroids for idiopathic thrombocytopenic purpura. A 55-year-old male with idiopathic thrombocytopenic purpura, treated with eltrombopag, developed a rapid decline in renal function following the increase in eltrombopag dose. Renal biopsy showed glomerular endothelial disorder and platelet thrombus, which suggested eltrombopag-induced renal-limited thrombotic microangiopathy.

Immunologic thrombocytopenic purpura (ITP) is a condition that affects four to 18 per 100 000 children every year. In most cases, spontaneous remission occurs, but splenectomy may be proposed. Exploring the site of platelet sequestration can help to better predict potential poor responders to splenectomy, but In-radiolabeled platelet scintigraphy (IPS) can be difficult to perform in children with very few platelets.
