Blood Review Series on Single-Cell Genomics

Allogeneic transplantation in older and infirm AML patients, cilta-cel in progressive multiple myeloma, and anti-CD20 therapy in relapsed TTP Jan 19, 2023

Show notes

In this week’s episode we’ll discuss the benefits of allogeneic hematopoietic stem cell transplantation in older and medically infirm patients with AML, learn more about the efficacy and safety of cilta-cel in patients with progressive multiple myeloma after exposure to other BCMA-targeting agents, and review the role of anti-CD20 therapy in relapsed immune-mediated thrombotic thrombocytopenic purpura.

Piezo antigens define a new blood group system, enasidenib in mutant-IDH2 relapsed/refractory AML, and breakthrough COVID-19 despite prophylaxis in B-cell malignancies Jan 12, 2023

Show notes

In this week’s episode, we’ll discuss new research revealing that the mechanosensory ion channel Piezo1 is the elusive carrier molecule of the Er blood group antigens, thus establishing a new blood group system. Next, we review results of a randomized phase 3 trial of enasidenib versus conventional treatment in late-stage mutant-IDH2 relapsed or refractory AML. Although the primary endpoint of overall survival was not met, investigators say the risk benefit ratio remains positive. Finally, we’ll review a study showing a clinically significant risk of breakthrough COVID-19 infections in patients with B-cell malignancies despite vaccination and pre-exposure prophylaxis with tixagevimab-cilgavimab during the Omicron era. However, hospitalization rates in the study were low and no deaths were reported.

Immune thrombocytopenia in pregnancy, ASCT in adults with inborn errors of immunity, and long-term health outcomes of childhood AML survivors Jan 05, 2023

Show notes

In this week’s episode we’ll discuss whether pregnancy increases the risk of bleeding in women with immune thrombocytopenia, compare the outcomes of allogeneic stem cell transplantation versus conservative management in adults with inborn errors of immunity, and learn more about the long-term health outcomes and late mortality in childhood AML survivors.

How I Treat Series: Management of High-risk Patients Following Allogeneic Transplant Jan 05, 2023

Show notes

In this episode, Associate Editor, Dr. Robert Zeiser and Dr. Yi-Bin Chen discuss the series on How I Manage High-Risk Patients Following Allogeneic Hematopoietic Cell Transplantation.

IL-13/IL-4 signaling and fibrotic progression in myelofibrosis, VWF-targeted thrombolysis in acute ischemic stroke, and NK cell dysfunction in relapsed AML Dec 29, 2022

Show notes

In this week’s episode, we'll discuss involvement of IL-13 and IL-4 signaling in fibrotic progression of myelofibrosis; next, we review results on a novel agent using vWF-dependent mechanisms to lyse pathological thrombi in acute ischemic stroke. Finally, we’ll shed new light on findings that implicate the GARP-TGF-beta-1 pathway in the loss of natural killer cell cytotoxicity in relapsed AML.

Effects of iron repletion on donor RBC quality, long-term outcomes in relapsed/refractory hairy cell leukemia after vemurafenib, and off-the-shelf cryopreserved platelets for detecting HIT Dec 22, 2022

Show notes

In this week’s episode, we’ll discuss the effects of iron repletion on the quality of donated red blood cells and donor well-being, learn more about the long-term outcomes of patients with relapsed/refractory hairy cell leukemia after vemurafenib monotherapy, and discuss the use of off-the-shelf cryopreserved platelets for detecting heparin-induced thrombocytopenia and vaccine-induced immune thrombotic thrombocytopenia.

Germline predisposition variants occur in all age groups in MDS, αβ-haplo-HCT excels in children with acute leukemias/MDS, and poor outcomes after CAR T cell failure in B-cell lymphomas Dec 15, 2022

Show notes

In this week’s episode, research shows that in patients with myelodysplastic syndromes, or MDS, the frequency of pathogenic or likely pathogenic germline variants is relatively high across all age groups, not just younger patients. Based on these results, it may be time to expand genetic testing to all patients. Next, we'll review primary results of a prospective, multicenter study of children with acute leukemias or MDS who underwent T-cell receptor αβ+ and CD19+ cell-depleted haploidentical HCT with reduced-toxicity conditioning. Finally, an emerging unmet need related to CAR T cell therapy: patients who progress after receiving CAR T cells have poor outcomes and no agreed upon standard of care. We’ll review findings from a large registry study demonstrating infrequent responses to post-CAR T cell treatment and short survival times, highlighting a need for novel strategies.

Predicting VTE in multiple myeloma, azithromycin promotes relapse after HSCT, and dual antigen targeted NK cells in B cell malignancies Dec 08, 2022

Show notes

In this week’s episode we’ll discuss the newly developed PRISM score for risk prediction of venous thromboembolism in multiple myeloma, learn more about relapse-promoting effects of azithromycin after allogeneic stem cell transplantation, and discuss the efficacy of off-the-shelf natural killer cells in preventing antigen escape in lymphoma and leukemia.

Using MRD to guide CLL treatment intensity, donor NK cells boost immune reconstitution after haplo-BMT, and EZH2 drives retinoic acid resistance in variant APL Dec 01, 2022

Show notes

In this week’s episode we discuss encouraging results of a phase 2 study using a sequential ibrutinib-venetoclax treatment approach driven by MRD findings in individual patients with chronic lymphocytic leukemia, or CLL. Next, we examine new research demonstrating that donor natural killer cells trigger release of beta-2 microglobulin by host dendritic cells, greatly accelerating donor-derived immune reconstitution after allogeneic bone marrow transplant in mice. We’ll look at the therapeutic implications of this as well. Lastly, we review a study of retinoic acid resistance in a mouse model of variant acute promyelocytic leukemia. Resistance was driven by the epigenetic regulator EZH2, which suggests the potential for an EZH2-targeted therapeutic approach.
