On day 7, she became febrile and chest CT imaging showed multiple nodules in both lung fields, and the serum galactomannan antigen index became positive, indicating probable IFD. Anti-fungal therapy with liposomal amphotericin B was immediately initiated; however, the patient's condition rapidly deteriorated, and she died on day 15. L. prolificans was later identified in blood culture tests that had been repeatedly performed while she had been febrile.

Recently, immunotherapy using both bispecific antibodies (BsAb) and chimeric antigen receptor T cells (CAR-T cells) has induced further anti-myeloma responses. Different agents must be combined to overcome the heterogeneity of myeloma cell clones, and new modalities for the treatment of refractory myeloma must also be developed to strengthen therapeutic effects. We have developed a novel BiTE (bispecific T-cell engager)-based modality, referred to as bridging-BiTE (B-BiTE). B-BiTE is able to bind to both an Fc domain of a human immunoglobulin G monoclonal antibody (mAb) and the human CD3 molecule. This enables rapid generation of a mAb/B-BiTE complex and safely induces dual-lymphoid activation of both human T cells and NK cells against myeloma cells. Importantly, sequential immunotherapy using two different mAb/B-BiTE complexes can produce deep and durable anti-myeloma responses. To further advance treatment of multiple myeloma, it is important to determine how to combine and sequence immunotherapy with other agents while considering management of unique adverse events caused by activated immune cells.</p>","PeriodicalId":93844,"journal":{"name":"[Rinsho ketsueki] The Japanese journal of clinical hematology","volume":"65 5","pages":"428-438"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141201489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Corticosteroids are the first-line treatment for cGVHD, but approximately 30% to 70% of patients develop steroid-refractory cGVHD (SR-cGVHD), which has an extremely poor prognosis. The pathophysiology of cGVHD is more complicated than acute GVHD, but recent advances using murine models in conjunction with human studies indicate three major phases: 1) acute inflammation, 2) chronic inflammation with loss of immune tolerance, and 3) disrupted target organ homeostasis and fibrosis. Strategies that help prevent cGVHD include optimal donor selection and choice of conditioning regimen as well as pharmacologic and graft manipulation strategies. The key cellular mediators of SR-cGVHD are T cells, B cells, antigen-presenting cells, and fibroblasts. T cells and B cells are now targetable with the inhibitors ibrutinib and ruxolitinib, respectively. Recently, promising results have been obtained by modulating pathologic T cell responses with Rock2 inhibitors and targeting fibrosis with CSF-1R inhibitors. To optimize the use of these medications, a better understanding of the biological and target organ-specific mechanisms of cGVHD is needed.
