Case report: Ensitrelvir for treatment of persistent COVID-19 in lymphoma patients: a report of two cases.

Persistent COVID-19 is a well recognized issue of concern in patients with hematological malignancies. Such patients are not only at risk of mortality due to the infection itself, but are also at risk of suboptimal malignancy-related outcomes because of delays and terminations of chemotherapy. We report two lymphoma patients with heavily pretreated persistent COVID-19 in which ensitrelvir brought about radical changes in the clinical course leading to rapid remissions.

Successful management of acute graft-versus-host disease with ibrutinib during cord blood transplantation for germline -mutated acute myeloid leukemia.

Background: Acute graft-versus-host disease (GVHD) is a major complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT) with significant morbidity and mortality, and efficacy of currently available therapeutics are limited. Acute and chronic GVHD are similar in that both are initiated by antigen presenting cells and activation of alloreactive B-cells and T-cells, subsequently leading to inflammation, tissue damage, and organ failure. One difference is that acute GVHD is mostly attributed to T-cell activation and cytokine release, whereas B-cells are the key players in chronic GVHD.

Hodgkin Lymphoma on Hemodialysis Successfully Treated with Extended Courses of Brentuximab Vedotin.

Chemotherapy for hemodialysis (HD) patients is a challenging situation because HD patients are generally frail, and the pharmacokinetics and pharmacodynamics of most chemotherapeutics in HD patients are unknown. We report a classical Hodgkin lymphoma (cHL) patient successfully treated with 34 courses of brentuximab vedotin (BV) monotherapy, of which 30 courses were carried out during HD. Although grade 2 peripheral sensory neuropathy and one occasion of febrile neutropenia were observed, treatment was well-tolerated overall and effective.
