YCU-AML2 xenograft mice models developed AML and mimicked the clinical phenotype of the original patient. YCU-AML2 expressed high sensitivity to MEK inhibitors, such as trametinib and selumetinib. Moreover, YCU-AML2 also exhibited high sensitivity to L-asparaginase with glutaminase activity, perhaps because of its reliance on oxidative phosphorylation via glutaminolysis as its main energy source. We believe that the YCU-AML2 cell line and its xenograft model can serve as models to explore the molecular pathogenesis of high-risk AML with KMT2A::MLLT3 rearrangement, MECOM overexpression, and/or KRAS mutation and develop new treatment strategies.","PeriodicalId":13992,"journal":{"name":"International Journal of Hematology","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143074406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

He survived due to treatment with factor XIII (FXIII) concentrates immediately after his FXIII antigen (Ag) level was reported to be < 5% of normal. Detailed examination by the Japanese Collaborative Research Group on autoimmune coagulation factor deficiencies revealed the presence of anti-FXIII-A and anti-FXIII-B subunit autoantibodies on immunoblot analyses, and thus autoimmune FXIII deficiency (AiF13D) was diagnosed based on the Japanese and international diagnostic criteria. Antibody eradication therapy with prednisolone was initiated and cyclophosphamide was added later. While FXIII:Ag levels remained at 40-50% of normal, bleeding did not recur even after stomach polypectomy. Experimental studies on patient specimens collected at the initial bleeding and later asymptomatic stages demonstrated the co-existence of clearance-accelerating and inhibitory anti-FXIII autoantibodies. The former type was predominant in both the bleeding and asymptomatic stages, whereas the latter became distinct in the asymptomatic stage. This is the first AiF13D patient to demonstrate such a change in anti-FXIII autoantibody type during the clinical course. This report discusses the relationship between autoantibody type and bleeding phenotype in detail, but future large studies are needed to confirm these observations.","PeriodicalId":13992,"journal":{"name":"International Journal of Hematology","volume":" ","pages":"257-264"},"PeriodicalIF":1.7,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142716154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Central nervous system (CNS) symptoms are rare manifestations of cGVHD, and are difficult to diagnose. CNS manifestations of cGVHD were discussed in the 2020 National Institutes of Health cGVHD Consensus Project as one of the \"atypical cGVHD manifestations\" with involvement of various organ systems other than classical cGVHD organs. We experienced a case of myelitis after allo-HSCT diagnosed as cGVHD of the CNS. The neurological symptoms progressed after corticosteroid pulse therapy, resulting in severe paralysis and paresthesia of the lower extremities. The clinical course and magnetic resonance imaging findings showed some similarities with multiple sclerosis. We decided to use rituximab after the patient became refractory to corticosteroids because rituximab has been reported to be effective in multiple sclerosis by suppressing B cells on both sides of the blood-brain barrier. Rituximab was effective for the neurologic symptoms in our case. In atypical cGVHD, treatments used in corresponding autoimmune diseases may be reasonable and effective.","PeriodicalId":13992,"journal":{"name":"International Journal of Hematology","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143065523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study, Part 4 of the guideline series, addresses DIC management in trauma, burns, obstetric complications, acute pancreatitis/liver failure, viral infections, and autoimmune diseases. For trauma-associated DIC, early administration of fresh-frozen plasma (FFP), coagulation factor concentrates such as fibrinogen and prothrombin complex concentrates, and tranexamic acid is recommended. The guidelines also highlight DIC in obstetrics, which is associated with massive bleeding, and recommend the administration of fibrinogen concentrate, antithrombin concentrate, and tranexamic acid. Through a systematic review of the current evidence, the guidelines provide stratified recommendations aimed at improving clinical outcomes in DIC management beyond sepsis, thereby serving as a valuable resource for healthcare providers globally.","PeriodicalId":13992,"journal":{"name":"International Journal of Hematology","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143074320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As calcineurin inhibitors (CNIs) reportedly contribute to TMA via drug-induced endothelial injury, treatment of TMA often involves CNI discontinuation or dose reduction. However, renal-limited TMA, defined as biopsy-proven renal TMA without the classical triad (hemolytic anemia, thrombocytopenia, and organ damage), has rarely been reported after allo-HSCT, and its optimal management remains unknown. Herein, we report three cases of renal-limited TMA after allo-HSCT that presented with nephrotic syndrome, in which renal biopsy showed TMA and concurrent membranous nephropathy. All patients were refractory to glucocorticoid monotherapy and the addition of CNIs led to complete remission of nephrotic syndrome. Renal-limited TMA after allo-HSCT may present as nephrotic syndrome with distinct pathophysiological features from renal-limited TMA in non-allo-HSCT recipients. Previous reports have suggested that renal-limited TMA after allo-HSCT is associated with renal graft-versus-host disease, and thus optimizing immunosuppressive therapy, including CNI treatment, may be useful. CNI treatment may be an option even in the presence of renal-limited TMA after allo-HSCT accompanied by concurrent membranous nephropathy.","PeriodicalId":13992,"journal":{"name":"International Journal of Hematology","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143065526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
