Severe Immune Effector Cell-Associated Neurotoxicity Syndrome in a Patient With Multiple Myeloma Treated With Elranatamab.

Elranatamab is an effective drug for triple-class-exposed relapsed/refractory multiple myeloma (TCE-RRMM). In the pivotal study, only grade 1 or 2 immune effector cell-associated neurotoxicity syndrome (ICANS) were reported, and the risk factors for immune effector cell-associated neurotoxicity syndrome have not yet been clearly elucidated. This case report documents the first case of grade 4 ICANS in a patient treated with elranatamab, presenting alongside grade 1 cytokine release syndrome (CRS).

DREAMM-11, Part 2: Japanese phase I trial of belantamab mafodotin combination therapies in relapsed/refractory multiple myeloma.

DREAMM-11 (NCT03828292) was a Phase 1, open-label, dose-escalation study of belantamab mafodotin in Japanese patients with relapsed/refractory multiple myeloma (RRMM). In Part 1, belantamab mafodotin monotherapy (2.5 or 3.

Acute myeloid leukemia with NUP98::RARG rearrangement: a case report and review of the relevant literature.

We herein report a rare case of acute myeloid leukemia (AML) with t(11;12)(p15;q13) and NUP98::RARG, which seems to be involved in the development of AML. The morphological features were similar to those of classic acute promyelocytic leukemia (APL), but unlike classic APL, this leukemia was resistant to treatment with all-trans retinoic acid (ATRA). We decided to use standard chemotherapy for AML with monitoring of minimal residual disease (MRD) by qualitative reverse transcriptase-polymerase chain reaction (RT-PCR) analysis for NUP98::RARG mRNA.

Local Cytokine Release Syndrome After Idecabtagene Vicleucel Therapy in Patients With Multiple Myeloma: Two Case Reports.

Chimeric antigen receptor T-cell (CAR-T) therapy targeting the B-cell maturation antigen (BCMA) is an effective treatment for patients with relapsed/refractory multiple myeloma (RRMM). However, cytokine release syndrome (CRS) represents a significant complication associated with CAR-T therapy. While most CRS cases involve systemic symptoms such as fever, hypotension, and respiratory distress, localized symptoms (referred to as local CRS) can also occur.

A case of acute eosinophilic pneumonia induced by the inhalation of acetylene.

A 58-year-old man who had inhaled acetylene while welding 2 and 4 days previously and subsequently developed cough, dyspnea, and fever was referred by his general practitioner. A computed tomography scan showed diffuse ground-glass opacities in both lungs, and bronchoalveolar lavage fluid showed an increased proportion of eosinophils (25 %). Acute eosinophilic pneumonia (AEP) was diagnosed.

A case of pulmonary mucosa-associated lymphoid tissue lymphoma diagnosed by detecting t(11;18)(q21;q21) in bronchial lavage fluid.

A 76-year-old woman was diagnosed with mucosa-associated lymphoid tissue (MALT) lymphoma by upper gastrointestinal endoscopy. She underwent further investigation for concomitant bilateral pleural effusions and right pulmonary consolidation. MALT lymphoma with the t(11; 18)(q21; q21) translocation and were detected in pleural fluid.

Allogeneic stem cell transplant with TBI-based myeloablative conditioning in adolescents and young adults with Philadelphia chromosome-negative ALL treated with pediatric protocols.

To investigate the safety of total body irradiation-based myeloablative conditioning (TBI-MAC) in adolescent and young adult (AYA) Philadelphia chromosome (Ph)-negative acute lymphoblastic leukemia (ALL) patients treated with pediatric protocols, treatment outcomes of 106 AYA patients aged 16-39 years old undergoing allogeneic stem cell transplant (allo-SCT) with TBI-MAC in the first remission were compared according to chemotherapy types before transplant. Pediatric and adult protocols were used in 56 and 50 of the patients, respectively. The cumulative incidence (CI) of non-relapse mortality (NRM) and the overall survival (OS) rates were not significantly different between the pediatric-protocol and adult-protocol group (NRM: 4 % vs.

[Retrospective analysis of allogeneic hematopoietic stem cell transplantation for multiple myeloma after myeloablative conditioning with 8 Gy of total body irradiation].

Allogeneic hematopoietic stem cell transplantation (allo-SCT) is a curative treatment option for multiple myeloma (MM), but few patients are eligible due to its high risk of treatment-related toxicity and relapse. Here, we report the feasibility and efficacy of allo-SCT after myeloablative conditioning with 8 Gy of total body irradiation (TBI) for reducing relapse of MM. We retrospectively analyzed data from 30 consecutive patients who received allo-SCT for MM after 8 Gy of TBI at Japanese Red Cross Medical Center between 2012 and 2021.

Prognostic value of the "dynamic" R2-ISS in patients with multiple myeloma undergoing anti-CD38 antibody-based triplet therapies.

To retrospectively analyze whether the second revision of the international staging system (R2-ISS) influenced prognosis at treatment initiation in patients with multiple myeloma (MM) receiving anti-CD38 antibody-based triplet treatments. High-risk chromosomal abnormalities were examined from diagnosis to treatment initiation and considered positive if detected once. R2-ISS was recalculated at the initiation of treatment and defined as "dynamic R2-ISS.

Striatal Blood Flow Changes by Middle Cerebral Artery Occlusion and Its Effect on Neurological Deficits in Mice.

Objective: We attempted to record the regional cerebral blood flow (CBF) simultaneously at various regions of the cerebral cortex and the striatum during middle cerebral artery (MCA) occlusion and to evaluate neurological deficits and infarct formation.

Methods: In male C57BL/6J mice, CBF was recorded in three regions including the ipsilateral cerebral cortex and the striatum with laser Doppler flowmeters, and the origin of MCA was occluded with a monofilament suture for 15-90 min. After 48 h, neurological deficits were evaluated, and infarct was examined by triphenyltetrazolium chloride (TTC) staining.

Cytomegalovirus infection during daratumumab therapy in patients with newly diagnosed multiple myeloma.

The introduction of daratumumab has improved treatment outcomes for multiple myeloma (MM). However, infectious complications are a concern in patients receiving daratumumab. Although some reports have explored the association between daratumumab and cytomegalovirus (CMV) infection, most of these have focused on relapsed or refractory cases, and few describe patients with newly diagnosed MM (NDMM).

Prototype and evaluation of automatic fingertip-blood-sampling system that uses fingertip blood-vessel images to determine puncture position.

We are developing an automatic fingertip-blood-sampling system to reduce the burden on trained medical personnel. For this system to withdraw a consistent volume of sampled blood for blood tests, we developed a mechanism for our system to select and puncture the vicinity of a large blood vessel from the blood-vessel image of an individual's fingertip. We call this mechanism the fingertip-vessel-puncture mechanism.

Characteristics and prognosis of patients with COVID-19 and hematological diseases in Japan: a cross-sectional study.

The Japanese Society of Hematology performed an observational cross-sectional study to clarify the morbidity, prognosis, and prognostic factors in patients with COVID-19 with hematological diseases (HDs) in Japan. The study included patients with HDs who enrolled in our epidemiological survey and had a COVID-19 diagnosis and a verified outcome of up to 2 months. The primary endpoints were characteristics and short-term prognosis of COVID-19 in patients with HDs.

[Updated treatment strategy for transplant-eligible multiple myeloma: current status and future perspectives].

Treatment outcomes of multiple myeloma (MM) have dramatically improved in the past 20 years. The IFM/DFCI group reported that triplet induction (bortezomib, lenalidomide, and dexamethasone), followed by up-front high-dose melphalan and autologous stem cell transplantation (HDM/ASCT) and maintenance therapy, demonstrated a median progression-free survival (PFS) of 50 months. Therefore, up-front HDM/ASCT is considered standard care even in the era of novel agents.
