    Abstract Aortitis is a rare adverse event of granulocyte colony-stimulating factor (G-CSF) treatment. Several previous studies have described recurrent aortitis caused by re-administration of the same G-CSF. However, no previous studies have examined the safety of switching between short-acting G-CSFs in patients who develop aortitis. We report the case of a 55-year-old man with refractory diffuse large B-cell lymphoma, who developed G-CSF-associated aortitis. The aortitis was triggered by filgrastim and recurred after treatment with lenograstim. The patient possessed human leukocyte antigen B52, which has been implicated in Takayasu arteritis. In addition, a drug-induced lymphocyte stimulation test for lenograstim performed upon detection of recurrent G-CSF-associated aortitis produced a positive result. Our case suggests that switching from one short-acting G-CSF to another does not prevent recurrence of G-CSF-associated aortitis. Although the etiology of G-CSF-associated aortitis has not been fully elucidated, our case also suggests that some patients may be genetically predisposed to aortitis.

    Abstract Immune thrombocytopenia (ITP) is characterized by early platelet destruction and impaired platelet production. Helicobacter pylori (H. pylori) infection seems to contribute to the pathogenesis in certain ITP patients in Japan. We compared the effectiveness of platelet transfusion in severe ITP in the presence or absence of H. pylori. The median corrected count increment (CCI) at 24 h after platelet transfusion (CCI-24) of the H. pylori-positive ITP patients was higher than that of the H. pylori-negative ITP patients (6463 vs. 754, p < 0.001), and the CCI-1 was also in the same direction but not significant (23 351 vs. 11 578). Multiple regression analyses showed that H. pylori infection was independently associated with CCI-24. Our study suggests that platelet transfusion may be more effective in H. pylori-positive ITP patients.

    Abstract Primary central nervous system lymphoma (PCNSL) is an extranodal type of lymphoma, which is treated with methotrexate (MTX)-based induction therapy. Although PCNSL is a hematological malignancy, patients with PCNSL may be treated at neurosurgery or hematology/oncology departments; however, the outcomes of PCNSL treatment have not been compared between these two departments. The present study compared the outcomes of 26 patients with newly diagnosed PCNSL that were treated at the Department of Neurological Surgery or Department of Hematology/Oncology (Wakayama Medical University Hospital, Wakayama, Japan) between January 2011 and December 2021. The relative dose intensity (RDI) and relative treatment intensity of MTX were assessed as indicators of the intensity of chemotherapy. The median RDI of MTX was 67 and 93% in the neurosurgery and hematology/oncology groups, respectively (P<0.001). The proportion of patients that achieved a complete response after high-dose MTX-based therapy was significantly higher in the hematology/oncology group than in the neurosurgery group (P=0.038). The estimated 2-year overall survival was 72 and 100% in the neurosurgery and hematology/oncology groups, respectively (P=0.046). As with the difference in the outcomes observed between pediatrics and hematology departments for adolescents with acute lymphoblastic leukemia, the outcomes of patients with PCNSL may differ between neurosurgery and hematology/oncology departments.

    Abstract A 44-year-old woman was diagnosed with acute myeloid leukemia (RUNX1::RUNX1T1 translocation) and received induction chemotherapy with idarubicin hydrochloride and cytosine arabinoside. The pneumonia that had been present since admission worsened, and a drug-induced skin rash appeared. On day 17, she presented with respiratory failure and shock, complicated by hemoconcentration and hypoalbuminemia. This was considered capillary leak syndrome due to pneumonia and drug allergy, so she was started on pulse steroid therapy and IVIG, and was intubated on the same day. On day 18, venovenous-extracorporeal membrane oxygenation (VV-ECMO) was started due to worsening blood gas parameters despite ventilatory management. Bronchoalveolar lavage fluid was serous, and both blood and sputum cultures yielded negative. The patient was weaned from VV-ECMO on day 26 as the pneumonia improved with recovery of hematopoiesis. She was disoriented, and a CT scan on day 28 revealed cerebral hemorrhage. Her strength recovered with rehabilitation. After induction chemotherapy, RUNX1::RUNX1T1 mRNA was not detected in bone marrow. The patient received consolidation chemotherapy, and has maintained complete remission. Severe respiratory failure during induction chemotherapy for acute leukemia can be fatal, but VV-ECMO may be lifesaving.

    Abstract The development of various autoimmune diseases has been reported after COVID-19 infections or vaccinations. However, no method for assessing the relationships between vaccines and the development of autoimmune diseases has been established. Aplastic anemia (AA) is an immune-mediated bone marrow failure syndrome. We report a case of severe AA that arose after the administration of a COVID-19 vaccine (the Pfizer-BioNTech mRNA vaccine), which was treated with allogeneic hematopoietic stem cell transplantation (HSCT). In this patient, antibodies against the SARS-CoV-2 spike protein were detected both before and after the HSCT. After the patient's hematopoietic stem cells were replaced through HSCT, his AA improved despite the presence of anti-SARS-CoV-2 antibodies. In this case, antibodies derived from the COVID-19 vaccine may not have been directly involved in the development of AA. This case suggests that the measurement of vaccine antibody titers before and after allogeneic HSCT may provide clues to the pathogenesis of vaccine-related autoimmune diseases. Although causality was not proven in this case, further evaluations are warranted to assess the associations between vaccines and AA.

    Abstract Introduction: The number of older patients with diffuse large B-cell lymphoma (DLBCL) is increasing. Although the standard treatment for newly diagnosed younger patients with DLBCL has been established, no consensus has been reached regarding the optimal chemotherapy intensity and regimen for older patients with DLBCL. In addition, no method for evaluating treatment intensity in retrospective studies when different numbers of chemotherapy courses are administered has been elucidated.
    Materials and methods: A multicenter retrospective analysis was conducted to evaluate the outcomes of a reduced-dose R-THP-COP regimen, which included 30 mg/m
    Results: The estimated four-year overall survival rates (OS) of the patients aged 75-80 and ≥ 80 were 55.1% and 60.6%, respectively. There was no significant difference in four-year OS between these age groups. In our cohort, there was no significant difference in the estimated four-year OS between the patients who received reduced-dose R-THP-COP at an RDI of ≥61% and those that received it at an RDI of <61% (P = 0.35). On the other hand, the patients who received reduced-dose R-THP-COP at an RTI of ≥2.7 exhibited a significantly higher estimated four-year OS than those treated at an RTI of <2.7 (68.5% vs. 28.7%; P < 0.001). Multivariate analysis revealed that the RTI was a significant independent predictor of OS. The cumulative incidence of treatment-related mortality (TRM) at one year was 4.2% and 3.4% in the 75-80 and ≥ 80 age groups, respectively. The cumulative incidence of TRM was significantly worse among the patients with Charlson Comorbidity Index (CCI) scores of ≥2 than among those with CCI scores of 0 or 1.
    Discussion: Our study suggests that the reduced-dose R-THP-COP regimen is a suitable treatment option for older patients with DLBCL, especially those with CCI scores of <2. Our study also showed that the RTI may be a valuable tool for assessing treatment intensity in retrospective studies involving older patients.

    Abstract Acquired hemophilia A (AHA) is a rare autoimmune bleeding disorder. Various autoimmune diseases, including AHA, have been reported to occur after the administration of mRNA COVID-19 vaccines. However, the characteristics of these AHA cases remain unclear. We report a case in which AHA arose in a young patient after the administration of an mRNA COVID-19 vaccine, but improved rapidly. The patient's factor VIII (FVIII) inhibitor titer spontaneously decreased to less than half of that seen at diagnosis. One week after the initial immunosuppressive therapy, the FVIII inhibitor had disappeared. Our case suggests that AHA that arises in young patients after COVID-19 vaccination may resolve spontaneously, and the levels of FVIII inhibitors may decrease more rapidly in such cases than in idiopathic AHA. Unlike for immune thrombocytopenic purpura (ITP), no acute type of AHA has been recognized. This case suggests that just as there is an acute type of ITP that develops in children/after vaccination, there may be an acute type of AHA that arises in young patients that receive mRNA COVID-19 vaccines.
