Transfusions remain a cornerstone treatment for patients with sickle cell disease. However, patients can develop potentially fatal hyperhemolytic transfusion complications, estimated to account for 4% of all sickle cell patient deaths, but since the clinical symptoms mimic those of in sickle cell pain crisis, it is likely that this rate underestimates the true incidence. In addition, the occurrence and progression of such hemolytic reactions from mild to severe is unpredictable. Mechanistic insight into how this complication develops and its pathologic consequences can lead to better prevention and treatment options for this life-threatening condition which is mostly encountered in sickle cell disease. This session will present recent developments in our understanding of potential mechanisms that may account for increased red cell destruction, including heme-driven alternative complement activation pathways, autoantibody-mediated destruction of patient's own red cells, and altered innate immune activation including those of phagocytes, and describe promising therapeutic strategies to control the associated inflammatory response for this complication in sickle cell disease.

Checkpoint Blockade: Defining A New Treatment Paradigm in Hodgkin Lymphoma and Allogeneic Transplantation

Discussed will be the current role of allogeneic hematopoietic cell transplantation in Hodgkin Lymphoma. With the advent of novel therapies including the antibody drug conjugate brentuximab vedotin and the checkpoint inhibitors nivolumab and pembrolizumab, outcomes in patients with Hodgkin Lymphoma have continued to improve, even in patients with more high risk disease. Concomitant with this progress, the number of patients referred for allogeneic HCT has decreased. Nevertheless, recent data suggest that patients with Hodgkin Lymphoma who undergo allogeneic HCT after exposure to checkpoint inhibitors have remarkable overall survival. The discussion will review recent data for allogeneic HCT in the era of checkpoint inhibitors including sequencing of therapies, and the impact of checkpoint inhibitors on GVHD, GVL and immune-related adverse events.
