Blood Podcast

In this week’s episode, we review results of a randomized, placebo-controlled phase 3 trial demonstrating that targeted inhibition of C1s with the monoclonal antibody sutimlimab is effective and well tolerated in non-transfusion-dependent patients with cold agglutinin disease. We’ll also review a population-based study evaluating the impact of adding either etoposide or autologous stem cell transplantation to CHOP in young and fit patients with peripheral T cell lymphomas. Finally, we’ll review a paper that elucidates a mechanism of lung injury in sickle cell disease. It involves gasdermin-D-dependent production of neutrophil extracellular traps in the liver, which travel intravascularly to the lung, where they promote occlusion of the pulmonary microcirculation.

In this week’s episode discuss the efficacy of rivaroxaban as antithrombotic prophylaxis after laparoscopic surgery for colorectal cancer, learn more about the association between genomic variants and survival outcomes after hematopoietic cell transplantation in severe aplastic anemia, and discuss the long-term safety and efficacy of fixed-duration venetoclax plus rituximab in relapsed/refractory CLL.

In this week’s episode, we’ll learn more about neuropsychiatric manifestations and stroke risk in hereditary TTP, discuss germline DDX41 variants as predisposing factors to myeloid neoplasms, and learn more about the prognostic impact of DDX41 mutations in adults with intensively treated AML.

In this week’s episode new research suggesting that, in patients with transplant-eligible multiple myeloma, adding daratumumab to first-line combination regimens may be a more cost effective strategy than saving it for second-line use. We’ll also review the work of researchers who applied base-editing technology to develop a complex and potent CAR T cell product for potential “off-the-shelf” use in patients with T-cell leukemias and other CD7-positive malignancies. Finally, we’ll review a paper that elucidates the role of SETBP1 mutations in chronic neutrophilic leukemia, pointing the way toward a potential multi-pronged therapeutic approach to this rare myeloproliferative neoplasm.

In this week’s episode we’ll discuss the factors influencing the development of immune thrombocytopenia after administration of the ChAdOx1 nCov-19 vaccine, learn about the genomic features underlying anti-CD19 CAR T-cell treatment failure in lymphoma, and introduce a new predictive model for risk assessment before CAR T-cell therapy for large B-cell lymphoma.

In this week’s episode we review a novel approach to generating autologous CD7-specific CAR T therapy for patients with T-cell malignancies that overcomes a key limitation: target-driven fratricide. We’ll also learn about new research pinpointing a key subset of exhausted CD4+ T cells in B- ALL, which also provides a rationale for combining tyrosine kinase inhibitors and PD-L1 blockers to reverse exhaustion and enhance leukemia clearance. Finally, we’ll discuss studies in a mouse model of acute ischemic stroke, showing that inhibiting phosphorylation of a tight junction protein in endothelial cells reduces risk of intracranial hemorrhage after treatment with recombinant tissue plasminogen activator.

In this week’s episode we first review new work revealing the critical role of the tension-sensitive cation channel PIEZO1 in the transendothelial migration of leukocytes. We’ll also review new research suggesting that CD8+ T-cells dimly expressing the CD4 antigen are increased in patients with various forms of secondary HLH, a finding that may have diagnostic, prognostic, and therapeutic significance. Finally, we’ll review a large, genome-wide association study identifying the ABO O blood group as a novel risk factor for heparin-induced thrombocytopenia—a finding that could have implications for prediction of this syndrome and for the management of related conditions.

In this week’s episode we’ll compare the long-term outcomes of ibrutinib-rituximab combination therapy versus FCR chemoimmunotherapy in chronic lymphocytic leukemia, discuss the role of procoagulant platelet sentinels in inflammatory bleeding, and learn more about variants in the SERPINC1 gene encoding antithrombin that cause severe thrombophilia.

Today we’ll learn more about the risk of subsequent malignancies in patients treated with genetically modified immune effector cells, discuss how p53 immunohistochemistry can be a global readout for TP53 alterations in AML, and uncover the role of CD19-negative CD22-positive B-cell progenitors in immune escape from CD19-directed therapies.
