Immune checkpoint inhibitors (ICIs) have been extensively investigated as a novel form of cancer therapy against a range of malignancies including urothelial carcinoma . Notably however, they have also been associated with unique toxicities known as immune-related adverse events (irAEs) which may involve any organs, including haematologic systems . The precise mechanisms involved in different irAEs are largely unknown, but they are believed to be associated with aberrant activation of immune systems induced by ICIs.

Abstract BACKGROUND: A standard approach to the recognition and management of major bleeding in immune thrombocytopenia (ITP) is lacking. METHODS: Retrospective cohort study of ITP patients presenting to the ED with severe thrombocytopenia (platelet count

AbstractThrombotic Microangiopathy (TMA) is a heterogeneous collection of syndromes that encompasses TTP, HUS, and other processes characterized by thrombocytopenia, microangiopathic hemolytic anemia, and, if untreated, organ failure and death. Novel therapies have recently been approved for the management of certain thrombotic microangiopathies, including caplacizumab for immune-mediated TTP, and eculizumab for atypical HUS. These options have complicated the standard workflow, which includes initiation of plasma exchange until ADAMTS13 testing can be resulted. Given such results may take several days, there is indecision...
We describe a 25-year-old man with isolated thrombocytopenia initially. He experienced recurrent seizures with stable thrombocytopenia after the first seizures related to intracranial hemorrhage. He was identified a novel c.3452C>T mutation by targeted exome sequencing. If a patient with thrombocytopenia shows recurrent seizures as well as renal, hearing, visual symptoms, MHA should be suspected and the targeted exome sequencing is considered an effective diagnostic tool.
The success of Intravenous Immunoglobulin in treating autoimmune and inflammatory processes such as immune thrombocytopenia purpura and Kawasaki disease has led to renewed interest in developing recombinant molecules capable of recapitulating these therapeutic effects. The anti-inflammatory properties of IVIG are, in part, due to the Fc region of the IgG molecule, which interacts with activating or inhibitory Fcγ receptors (FcγRs), the neonatal Fc Receptor, non-canonical FcRs expressed by immune cells and complement proteins. In most cases, Fc interactions with these cognate receptors are dependent upon avidity...
Conclusion: Apatinib is actively used in treating patients with recurrent AM. A randomized trial and phase II clinical trial of this inhibitor should be performed to further evaluate its efficacy in treating malignant meningioma. PMID: 32212907 [PubMed - as supplied by publisher]
Authors: Davenport P, Liu ZJ, Sola-Visner M Abstract A growing body of research has made it increasingly clear that there are substantial biological differences between fetal/neonatal and adult megakaryopoiesis. Over the last decade, studies revealed a developmentally unique uncoupling of proliferation, polyploidization, and cytoplasmic maturation in neonatal MKs that results in the production of large numbers of small, low ploidy, but mature MKs during this period of development, and identified substantial molecular differences between fetal/neonatal and adult MKs. This review will summarize our current knowledge ...
