    New insights on PU.1-mutated agammaglobulinemia; venetoclax-based induction therapy in younger AML patients; the link between ABO Blood groups and risk of future VTE

    In this week's episode, we'll hear about new insights into PU.1-mutated agammaglobulinemia. Researchers show that haploinsufficiency of the master transcriptional regulator PU.1 causes agammaglobulinemia and dendritic cell deficiencies. These patients experience an array of infectious and non-infectious complications, but not leukemia. After that: venetoclax-based induction therapy in younger patients with AML. Venetoclax plus decitabine was associated with superior safety and non-inferior response rates compared to intensive chemotherapy. Is it time to consider lower-intensity therapy beyond older and unfit patients? Finally, a focus on venous thromboembolism. Researchers link BGAT, an enzyme pivotal to determining blood type, to risk of future VTE. They say high plasma levels of BGAT contribute to risk above and beyond what can be explained by von Willebrand factor and Factor VIII.Featured Articles:One hundred thirty-four germ line PU.1 variants and the agammaglobulinemic patients carrying themVenetoclax and decitabine vs intensive chemotherapy as induction for young patients with newly diagnosed AMLHisto–blood group ABO system transferase plasma levels and risk of future venous thromboembolism: the HUNT study

    In this week's episode, we'll learn about stopping myeloma maintenance therapy in the modern era. New research suggests that many patients in remission can discontinue lenalidomide, remaining treatment-free, without jeopardizing disease response. After that: a novel congenital neutropenia syndrome. Mutations in the COPZ1 gene impact myeloid differentiation and development of neutropenia. Researchers describe the mechanisms and propose a treatment strategy for restoring granulopoiesis. Finally, ruxolitinib maintenance therapy after allogeneic transplant. In a phase 2 study, this treatment strategy was associated with low rates of chronic graft-versus-host disease. Investigators say the use of JAK inhibitors in this context warrants further study.Featured Articles: Sustained bone marrow and imaging MRD negativity for 3 years drives discontinuation of maintenance post-ASCT in myelomaA new severe congenital neutropenia syndrome associated with autosomal recessive COPZ1 mutationsLow rates of chronic graft-versus-host disease with ruxolitinib maintenance following allogeneic HCT

    In this week's episode, we'll hear about how researchers look toward the lung, and find uniquely programmed blood stem cells. This study is the first to fully characterize hematopoietic stem and progenitor cells in the adult human lung. After that: researchers develop a neural network-based probabilistic classifier, DLBclass, that assigns all diffuse large B-cell lymphomas into one of five genetic subtypes. It's an inclusive taxonomy that they say provides actionable genetic information in almost all patients with DLBCL. Finally, new insights on NETS, or neutrophil extracellular traps. In the liver vasculature, NET removal leads to secondary inflammation, resulting in new waves of NETS that may impact future infection. We'll review these and other findings from this recent mouse model study.Featured Articles:Decoding functional hematopoietic progenitor cells in the adult human lungDLBclass: a probabilistic molecular classifier to guide clinical investigation and practice in diffuse large B-cell lymphomaDonor regulatory T-cell therapy to prevent graft-versus-host disease

    In this week's episode we'll learn about the role of autologous transplant for relapsed myeloma. In an updated analysis of the GMMG ReLApsE trial, salvage autologous transplant offered no survival benefit compared to control chemotherapy. These findings may have clinical implications in an era of alternative, and highly effective, treatment options. After that: Response to DDAVP, or desmopressin, in bleeding disorders. This study is the first large scale meta-analysis to assess the response rate to DDAVP in bleeding disorders. Authors provide new insights into determinants of response, which vary according to the disease type. Finally, turning to diffuse large B cell lymphoma. Germinal center B cells depend on the activity of DOT1 and EZH2 to maintain their pro-proliferative identity. New research shows that combined treatment with DOT1L and EZH2 inhibitors has synergistic activity in vitro.Featured Articles:Salvage autologous transplant in relapsed multiple myeloma: long-term follow-up of the phase 3 GMMG ReLApsE trialDDAVP response and its determinants in bleeding disorders: a systematic review and meta-analysisTargeting DOT1L and EZH2 synergizes in breaking the germinal center identity of diffuse large B-cell lymphoma

Researchers demonstrate that over time, platelet function shifts away from hemostasis and toward a more immunomodulatory role. These finding could have important implications for transfusion medicine and certain platelet-related disease states. After that, use of odronextamab, a CD20×CD3 bispecific antibody, in patients with diffuse large B-cell lymphoma, or DLBCL, progressing after CAR T cell therapy. The study is the first to evaluate the efficacy and safety of this therapy in the post-CAR T cell treatment setting.

The discovery that Mal protein is expressed on red blood cell membranes of AnWj-positive, but not AnWj-negative individuals, and that homozygous deletion in MAL causes the AnWj-negative blood group phenotype, helps answer a decades-old mystery related to the high prevalence red blood cell antigen AnWj and forms the basis of a new blood group system.

Zanubrutinib, venetoclax and obinutuzumab induced deep remissions, and was well tolerated, even in very high-risk patients, and those with prior exposure to targeted therapies. After that: researchers chronicle the development of a patient-reported outcome measure for sclerosis associated with chronic GVHD—graft-versus-host disease. The new symptom scale—currently undergoing validation studies—may provide valuable information regarding severity, functional impact, and response to therapy. Finally, a study of changes in population dynamic rates that underlie inflammation-associated myeloid bias.

    In this week's podcast, a potential new therapeutic target in beta-thalassemia. The E3 ubiquitin ligase AMBRA1 promotes autophagic clearance of free alpha-globin. Researchers describe mutations in the AMBRA1 gene that impair this clearance, exacerbating ineffective erythropoiesis and disease severity. After that: targeting MYD88 mutations. Lasalocid-A is a compound that selectively binds to the MYD88 L265P mutant protein, which is found in a range of B-cell lymphomas. New research shows its potential to inhibit tumor growth, overcome ibrutinib resistance, and synergize with venetoclax. Finally: air pollution is linked to an increased risk of venous thromboembolism in a prospective, community-based cohort study. The findings highlight the harms of pollution, and support the case for global efforts to improve public health.Featured Articles:Mutations in AMBRA1 aggravate β-thalassemia by impairing autophagy-mediated clearance of free α-globinLasalocid A selectively induces the degradation of MYD88 in lymphomas harboring the MYD88 L265P mutationAir pollution is associated with increased risk of venous thromboembolism: the Multi-Ethnic Study of Atherosclerosis
