Autoimmune Cytopenias


  • Autoimmune Cytopenias Recent Advances in the Mechanisms and Treatment of Immune Thrombocytopenia

    The authors of this February review in EBioMedicine note that treatment for immune thrombocytopenia (ITP) is shifting away from immune suppression and toward use of newer therapeutic agents such as thrombopoietin receptor agonists, which "have transformed ITP care…have high efficacy, are well tolerated, and improve patients' quality of life." The authors outline newer targeted therapies in ITP, including inhibitors of the neonatal Fc receptor inhibitors, Bruton tyrosine kinase, and the complement pathway. Mechanisms underlying ITP and new approaches to ITP care are discussed.

  • Autoimmune Cytopenias Assessment and Management of Immune Thrombocytopenia (ITP) in the Emergency Department: Current Perspectives

    In this review in Open Access Emergency Medicine, emergency department (ED) healthcare providers from Miami, Florida, discuss current literature and guidelines relevant to the care of both pediatric and adult patients with immune thrombocytopenia who present to the ED. They highlight the epidemiology, clinical presentation, diagnosis (including tests to avoid or defer in the ED), and treatment of this blood disorder; and briefly outline management of ITP in pregnant patients and patients with COVID-19.

  • Autoimmune Cytopenias SARS-CoV-2 Vaccination and Immune Thrombocytopenia in de Novo and Pre-Existing ITP Patients

    In this review article, published in Blood in late November 2021, researchers used 4 large data sources to ultimately evaluate the impact of SARS-CoV-2 vaccination in 109 patients with pre-existing immune thrombocytopenia (ITP). One key finding was that splenectomy and past use of 5 or more therapies were predictive of higher risk of worsening thrombocytopenia following receipt of the SARS-CoV-2 vaccine in patients with ITP. While concluding that vaccination against COVID-19 is "generally safe" in the setting of ITP, they advised that "thrombocytopenia exacerbation may occur and requires monitoring."
