■ Paper- Monovalent Omicron XBB.1.5 mRNA vaccines were newly developed and approved by the FDA in Autumn 2023 for preventing COVID-19. However, clinical efficacy for these vaccines is currently lacking. We previously established the quantification of antigen-specific antibody sequence (QASAS) method to assess the response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination at the mRNA level using B-cell receptor (BCR) repertoire assay and the coronavirus antibody database (CoV-AbDab). Here, we used this method to evaluate the immunogenicity of monovalent XBB.1.5 vaccines. We analyzed repeated blood samples of healthy volunteers before and after monovalent XBB.1.5 vaccination (BNT162b2 XBB.1.5 or mRNA-1273.815) for the BCR repertoire to assess BCR/antibody sequences that matched SARS-CoV-2-specific sequences in the database. The number of matched unique sequences and their total reads quickly increased 1 week after vaccination. Matched sequences included those bound to the Omicron strain and Omicron XBB sublineage. The antibody sequences that can bind to the Omicron strain and XBB sublineage revealed that the monovalent XBB.1.5 vaccines showed a stronger response than previous vaccines or SARS-CoV-2 infection before the emergence of XBB sublineage. The QASAS method was able to demonstrate the immunogenic effect of monovalent XBB.1.5 vaccines for the 2023-2024 COVID-19 vaccination campaign.Aug. 2024, EJHaem, 5(4) (4), 661 - 668, English, International magazineScientific journal
- BACKGROUND: We previously demonstrated that CD34 + cell transplantation in animals healed intractable fractures via osteogenesis and vasculogenesis; we also demonstrated the safety and efficacy of this cell therapy in an earlier phase I/II clinical trial conducted on seven patients with fracture nonunion. Herein, we present the results of a phase III clinical trial conducted to confirm the results of the previous phase studies using a larger cohort of patients. METHODS: CD34 + cells were mobilized via administration of granulocyte colony-stimulating factor, harvested using leukapheresis, and isolated using magnetic cell sorting. Autologous CD34 + cells were transplanted in 15 patients with tibia nonunion and 10 patients with femur nonunion, who were followed up for 52 weeks post transplantation. The main outcome was a reduction in time to heal the tibia in nonunion patients compared with that in historical control patients. We calculated the required number of patients as 15 based on the results of the phase I/II study. An independent data monitoring committee performed the radiographic assessments. Adverse events and medical device failures were recorded. RESULTS: All fractures healed during the study period. The time to radiological fracture healing was 2.8 times shorter in patients with CD34 + cell transplantation than in the historical control group (hazard ratio: 2.81 and 95% confidence interval 1.16-6.85); moreover, no safety concerns were observed. CONCLUSIONS: Our findings strongly suggest that autologous CD34 + cell transplantation is a novel treatment option for fracture nonunion. TRIAL REGISTRATION: UMIN-CTR, UMIN000022814.

- The use of anti-SARS-CoV-2 antibody products like tixagevimab/cilgavimab represents an important strategy to protect immunocompromised patients with haematological malignancies from COVID-19. Although patients who receive these agents should still be vaccinated, the use of tixagevimab/cilgavimab can mask the production of anti-spike antibody after vaccination, making it hard to assess vaccine response. We have newly established a quantification method to assess the response to SARS-CoV-2 vaccination at the mRNA level using B-cell receptor (BCR) repertoire assay and the Coronavirus Antibody Database (CoV-AbDab). Repeated blood samples before and after vaccination were analysed for the BCR repertoire, and BCR sequences were searched in the database. We analysed the number and percentage frequency of matched sequences. We found that the number of matched sequences increased 2 weeks after the first vaccination and quickly decreased. Meanwhile, the number of matched sequences more rapidly increased after the second vaccination. These results show that the postvaccine immune response can be assessed at the mRNA level by analysing the fluctuation in matching sequences. Finally, BCR repertoire analysis with CoV-AbDab clearly demonstrated the response to mRNA SARS-CoV-2 vaccination even after tixagevimab/cilgavimab administration in haematological malignancy patients who underwent allogeneic haematopoietic stem cell transplantation.Jun. 2023, British journal of haematology, 202(3) (3), 504 - 516, English, International magazineScientific journal
- Abstract Sinusoidal obstruction syndrome (SOS) is a fatal complication of hematopoietic stem cell transplantation (HSCT). Early diagnosis for SOS can improve clinical outcomes significantly. Here, we performed a retrospective study to investigate the Cairo diagnostic criteria, in which SOS was defined as the development of two or more in seven events, including transfusion‐refractory thrombocytopenia. Among 154 cases of allogeneic HSCT, 10 cases of SOS using the European Society for Blood and Marrow Transplantation criteria (EBMT16) as the reference standard were identified. The original Cairo criteria could diagnose SOS 5 days earlier than any other established criteria, with some false‐positive results (sensitivity = 100.0%; specificity = 72.2%). When the cutoff was set to three events for the Cairo criteria, the diagnosis of SOS could be made 3 days earlier than that using the EBMT16 criteria, with comparable precision (specificity = 86.1%). The accuracy of the Cairo criteria improved further when the cutoff point was set to four (specificity = 93.8%). The fulfillment of the Cairo criteria was associated with high mortality. Based on our results, the Cairo criteria were also considered clinically useful, especially at three or four cutoff points. Further studies are required to validate and refine the criteria.Wiley, Jun. 2023, eJHaemScientific journal
- In acute myeloid leukemia (AML), the heterogeneity of genetic and epigenetic characteristics makes treatment difficult. The prognosis for AML is therefore poor, and there is an urgent need for new treatments for this condition. Gemtuzumab ozogamicin (GO), the first antibody-drug conjugate (ADC), targets the CD33 antigen expressed in over 90% of AML cases. GO therefore has the potential to counter the heterogeneity of AML patients. However, a major clinical problem is that drug resistance to GO diminishes its effect over time. Here, we report that the inhibition of glycogen synthase kinase 3 (GSK3) alone overcomes several forms of GO resistance at concentrations without antileukemic effects. The GSK3 inhibitors tested significantly enhanced the cytotoxic effect of GO in AML cell lines. We elucidated four mechanisms of enhancement: (1) increased expression of CD33, the target antigen of GO; (2) activation of a lysosomal function essential for hydrolysis of the GO linker; (3) reduced expression of MDR1 that eliminates calicheamicin, the payload of GO; and (4) reduced expression of the anti-apoptotic factor Bcl-2. A similar combination effect was observed against patient-derived primary AML cells. Combining GO with GSK3 inhibitors may be efficacious in treating heterogeneous AML.Feb. 2023, EJHaem, 4(1) (1), 153 - 164, English, International magazineScientific journal

- We previously reported that a second dose of BNT162b2 was safe and effective for allogeneic hematopoietic stem cell transplantation (HSCT) patients. Here, we investigated the safety and efficacy of a third dose of COVID-19 mRNA vaccine in allogeneic HSCT patients. Antibody titers against the S1 spike protein were measured using the QuaResearch COVID-19 Human IgM IgG ELISA kit. The previous study included 25 allogeneic HSCT patients who received two doses of BNT162b2. Following the exclusion of three patients because of the development of COVID-19 (n = 2) and loss to follow-up (n = 1), the study evaluated 22 allogeneic HSCT patients who received a third dose of COVID-19 mRNA vaccine (BNT162b2 [n = 15] and mRNA-1273 [n = 7]). Median age at the time of the first vaccination was 56 (range, 23-71) years. Five patients were receiving immunosuppressants at the third vaccination, namely calcineurin inhibitors (CI) alone (n = 1), steroids alone (n = 2), or CI combined with steroids (n = 2). Twenty-one patients (95%) seroconverted after the third dose. None of our patients had serious adverse events, new-onset graft-versus-host disease (GVHD), or GVHD exacerbation after vaccination. A third dose of the BNT162b2 and mRNA-1273 COVID-19 vaccines was safe and effective for allogeneic HSCT patients.Oct. 2022, Vaccines, 10(11) (11), English, International magazineScientific journal

- Anti-CD20 antibodies react with CD20 expressed not only on malignant B cells, but also on normal B cells. It has been reported that patients treated with anti-CD20 antibodies had an insufficient response to two-dose mRNA SARS-CoV-2 vaccination. To investigate the efficacy of a third dose in these patients, we investigated serum IgG antibody titers for the S1 protein after a third vaccination in 22 patients treated with the anti-CD20 antibody who failed two-dose vaccination. Results showed that overall, 50% of patients seroconverted. Although no patient who received the third dose within 1 year of the last anti-CD20 antibody administration showed an increase in S1 antibody titer, 69% of patients who received the third dose more than 1 year after the last anti-CD20 antibody administration seroconverted. Our data show that a third dose of vaccination is effective in improving the seroconversion rate in patients treated with the anti-CD20 antibody who failed standard two-dose vaccination.Jun. 2022, Vaccines (Basel), 10(6) (6), 965, English, International magazine[Refereed]Scientific journal

- Patients who have undergone hematopoietic stem cell transplantation (HSCT) for hematological disease experience high mortality when infected by coronavirus disease 2019 (COVID-19). However, the safety and efficacy of the COVID-19 vaccine in HSCT patients remain to be investigated. We prospectively evaluated the safety and immunogenicity of the BNT162b2 mRNA COVID-19 vaccine (Pfizer BioNTech) in 25 Japanese allogeneic HSCT patients in comparison with 19 healthy volunteers. While anti-S1 antibody titers in almost all healthy volunteers after the second dose were higher than the cut-off value reported previously, levels in HSCT patients after the second dose were diverse. Nineteen patients (76%) had seroconversion of anti-S1 IgG. The median optical density of antibody levels in HSCT patients with low IgG levels (<600 mg/dL), steroid treatment, or low lymphocytes (<1000/μL) was significantly lower than that in the other HSCT patients. There were no serious adverse events (>Grade 3) and no new development or exacerbation of graft-versus-host disease after vaccination. We concluded that the BNT162b2 mRNA vaccine is safe and effective in Japanese allogeneic HSCT patients.Jan. 2022, Vaccines (Basel), 10(2) (2), 158, English, International magazine[Refereed]Scientific journal
- We investigated the efficacy of BNT162b2 mRNA COVID-19 vaccine in patients with B-cell malignancies treated with anti-CD20 antibody. Although T-cell-mediated immune responses were detected even in patients receiving R-CHOP treatment, the S1 antibody titer following BNT162b2 vaccination remained only marginally increased for more than 3 years after the final dose of anti-CD20 antibody. We found no relationship between the percent of B-cells and S1 antibody titer. The duration of this suppression was much longer than we anticipated. Further protection and treatment strategies against COVID-19 for these patients are warranted.Jan. 2022, International journal of Hematology, 115(1) (1), 7 - 10, English, Domestic magazine[Refereed]Scientific journal

- Autoimmune hemolytic anemia (AIHA) is a rare comorbidity in colorectal cancer (CRC) and has an unknown etiology. Previously, we described an AIHA case secondary to CRC with ectopic band 3 expression. Herein, we investigated ectopic band 3 expression and erythrocyte membrane-bound IgG in a CRC cohort. Between September 2016 and August 2018, 50 patients with CRC and 26 healthy controls were enrolled in the present study. The expression of band 3 and SLC4A1 mRNA was observed in 97% of CRC surgical specimens. Although clinical AIHA was not observed in any patient with CRC, a direct antiglobulin test was positive in 10 of the patients in the CRC group (p = 0.01). Flow cytometry revealed significantly increased erythrocyte membrane-bound IgG among patients with CRC compared to healthy controls (mean ± standard deviation; 38.8 ± 4.7 vs. 29.9 ± 15.6, p = 0.012). Normocytic anemia was observed, including in cases negative for fecal occult blood, suggesting a shortened erythrocyte life-span due to increased membrane-bound IgG. Immunoprecipitation revealed increased anti-band 3 autoantibodies in patients' sera. Mouse experiments recapitulated this phenomenon. We also confirmed that band 3 expression is controlled by 5'AMP-activated protein kinase under hypoxic conditions. These findings increase our understanding of the etiology of cancer-related anemia.Corresponding, May 2020, International journal of hematology, 111(5) (5), 657 - 666, English, Domestic magazine[Refereed]Scientific journal

- A 45-year-old woman was diagnosed with hepatosplenic T-cell lymphoma (HSTCL), a rare subtype of peripheral T-cell lymphoma. She received different types of chemotherapy, but disease progression was observed. To reduce the tumor burden before an unrelated bone marrow transplantation, combination chemotherapy consisting of the gemcitabine, carboplatin, and dexamethasone (GCD) was administered as bridging therapy, resulting in a reduction in the number of lymphoma cells. We were then able to perform bone marrow transplantation. Although she experienced some adverse events, she successfully achieved long-term remission. We herein report a successful case of HSTCL treated with unrelated stem cell transplantation following the GCD regimen as bridging chemotherapy.Mar. 2019, Intern Med., 58(5) (5), 707 - 712, English, Domestic magazine[Refereed]Scientific journal
- BACKGROUND: Human herpesvirus 6 (HHV-6) encephalitis is a known life-threatening complication following allogeneic hematopoietic stem cell transplantation (allo-HSCT). However, few studies have focused on the occurrence of HHV-6 encephalitis in patients receiving mycophenolate mofetil (MMF) combined with a calcineurin inhibitor as prophylaxis for graft-versus-host disease (GVHD). This study aimed to investigate the impact of MMF administered for GVHD prophylaxis in the occurrence of HHV-6 encephalitis after allo-HSCT and the characteristics of this condition. METHODS AND RESULTS: We retrospectively analyzed 73 patients who underwent allo-HSCT (83 transplants) at our hospital between April 2010 and December 2015. MMF (2-3 g/d) was administered along with a calcineurin inhibitor. Seven patients (8.0%) developed encephalitis due to HHV-6. The median period from allo-HSCT to the onset of HHV-6 encephalitis was 23 days (range, 17-98 days). The cumulative incidence of HHV-6 encephalitis on day 100 after treatment was 12% and 6% in patients who underwent cord blood transplantation (CBT) and non-CBT (ie, bone marrow transplantation and peripheral blood stem cell transplantation), respectively (P = 0.344). Neurological symptoms of encephalitis were more severe in non-CBT cases than those in CBT cases. All patients diagnosed with HHV-6 encephalitis were treated with ganciclovir or foscarnet. None of the enrolled patients died from HHV-6 encephalitis. CONCLUSIONS: Mycophenolate mofetil may have the potential to increase the frequency of severe HHV-6 encephalitis in patients undergoing CBT and non-CBT. Thus, MMF should be administered with caution, and patients should be monitored closely for HHV-6 encephalitis even those who did not undergo CBT.Feb. 2019, Transpl Infect Dis., 21(1) (1), e13024, English, International magazine[Refereed]Scientific journal
- Cancer patients occasionally have anemia with high mean corpuscular volume in addition to iron deficiency anemia. Secondary autoimmune hemolytic anemia (AIHA) following cancer is also observed with low frequency. To date, no causal mechanisms for these disease states have been reported. Here, we present the case of an 80-year-old woman with AIHA that was resistant to prednisolone. Further examinations revealed primary adenocarcinoma of the sigmoid colon and primary squamous cell carcinoma in the right lung. After resections of these tumors, her anemia partially improved until a colon cancer-derived metastatic tumor was detected in the left lung. Immunoprecipitation of erythrocyte membrane proteins with an autoantibody followed by mass spectrometry/Western blotting identified band 3 as the target of the autoantibody. Immunohistochemical analysis revealed ectopic expression of band 3 in the colon adenocarcinoma. To our knowledge, this is the first report that identifies the cause in a case of anemia without bleeding in a cancer patient and that defines a mechanism underlying secondary AIHA following cancer progression.Jan. 2019, Hum Pathol, 83, 193 - 198, English, International magazine[Refereed]Scientific journal
- Scopulariopsis alboflavescens is a soil saprophyte that is widely distributed in nature. Recently, there have been increasing number of reports of invasive infections with Scopulariopsis species in immunocompromised patients. In this report, we described an adult woman with acute myeloid leukemia and who developed S. alboflavescens pneumonia. Liposomal amphotericin B and voriconazole combination therapy was unsuccessful and the patient died because of pneumonia. Scopulariopsis is highly resistant to available antifungal agents and almost invariably fatal. This case report should alert clinicians to the importance of listing Scopulariopsis as a pathogenic fungus in immunocompromised patients.Dec. 2018, Int J Hematol., 108(6) (6), 658 - 664, English, Domestic magazine[Refereed]Scientific journal

- Lymph node infarction is very rare, and is frequently associated with neoplasms, such as malignant lymphoma and non-neoplastic disease, or interventions such as fine-needle aspiration (FNA). A 76-year-old-man presented with cervical lymph node swelling. Although FNA was performed, the findings were insufficient for a definitive diagnosis. Consequently, surgical biopsy of the cervical lymph node was performed, which revealed total infarction; a diagnosis of classical Hodgkin lymphoma was made later. Both lymphoma itself and FNA may cause total lymph node infarction, which makes diagnosis confusing. Therefore, it is important to repeat the biopsy rather than repeat FNA to correctly diagnose malignant lymphoma, including Hodgkin lymphoma.Mar. 2018, Journal of clinical and experimental hematopathology : JCEH, 58(1) (1), 24 - 26, English, Domestic magazine[Refereed]Scientific journal

- Constitutional translocations that coincide with t(9;22)(q34;q11.2) may lead to unnecessary treatments in chronic myeloid leukemia (CML) patients, as, under the standard criteria, a diagnosis of CML with additional chromosomal abnormalities indicates an accelerated phase (AP). In the present report, a 47-year-old male had pain in the right foot due to gout. Peripheral blood examination showed leukocytosis with left shift. Bone marrow aspiration revealed myeloid hyperplasia with megakaryocytosis. RT-PCR revealed the major BCR-ABL fusion transcript, and CML in the chronic phase was diagnosed, followed by nilotinib treatment. Although WBC counts decreased immediately, G-banding analysis showed 46,XY,t(8;22)(q24;q11.2),t(9;22)(q34;q11.2) [20]. The t(8;22)(q24;q11.2) translocation is known to be recurrent in Burkitt's lymphoma. The diagnosis was changed to CML in AP, leading to B-lymphoid crisis. Unexpectedly, the karyotype was 46,XY,t(8;22)(q24;q11.2) [20] in hematological complete remission, even after 3 months. Fluorescence in situ hybridization on metaphase spreads revealed the MYC signal on the der(22)t(8;22), indicating that the 8q24 breakpoint was centromeric to MYC at 8q24.21. G-banding analysis of phytohemagglutinin-stimulated peripheral blood T-lymphocytes also indicated 46,XY,t(8;22)(q24.1;q11.2). We conclude that the t(8;22) is constitutional in this patient. As the tumor suppressor gene TRC8/RNF139 is disrupted by constitutional t(8;22)(q24.13;q11.21) in dysgerminoma, it may be associated with the onset of CML.Feb. 2017, International Journal of Hematology, 105(2) (2), 226 - 229, English, Domestic magazine[Refereed]Scientific journal

A 49-year-old female was initially diagnosed with acute myeloid leukemia (AML) M4 with a CD45+CD13+CD33+CD34−HLA-DR+ immunophenotype. She underwent allogeneic bone marrow transplantation, but the disease recurred. The bone marrow was infiltrated with 87.0% blasts negative for myeloperoxidase (MPO) staining. Immunophenotyping by flow cytometry identified the presence of a CD45-negative blast population. These blasts exhibited a CD13+CD33+CD19−CD10−CD34−HLA-DR− immunophenotype. The lack of CD45 expression is often observed in B-cell acute lymphoblastic leukemia, whereas CD45-negative AML is extremely rare; only one older male with AML-M0 has been reported. In the present case, the CD45-negative blasts had an MPO−CD13+CD33+ phenotype, which is similar to AML-M0.
- Oncogene amplification is uncommon in acute myeloid leukemia (AML). Cytogenetically, it is primarily found as double minute chromosomes (dmin) or homogeneously staining regions (hsr). A 62-year-old woman was admitted to our hospital because of anemia and thrombocytopenia. Her bone marrow was hypercellular with 78.6% myeloperoxidase- positive blasts. Some had micronuclei. The patient was diagnosed with AML M2 and remains in complete remission (CR) after induction therapy. G-banding at diagnosis showed 51,XX,t(11;16)(q13;p11.2),+r1,+mar1×4. Spectral karyotyping confirmed t(11;16) and revealed that the ring and the marker chromosomes were derived from multiple copies of ring chromosome 8. Fluorescence in situ hybridization (FISH) with a MYC probe at 8q24 detected amplified MYC signals on 1 large and 4 small ring chromosomes 8. One MYC signal was deleted from one of the 2 chromosomes 8. FISH with a FUS probe at 16p11.2 showed monoallelic deletion of FUS. Immunohistochemistry demonstrated MYC protein overexpression at diagnosis and almost negative expression in CR. These results indicate that MYC amplification could occur in ring chromosomes without dmin. A cryptic MYC deletion suggests that an episome model could be applicable to MYC amplification in ring chromosomes as observed for dmin and hsr. Furthermore, considering 2 further reported cases, t(11;16)(q13;p11) may be a very rare but recurrent translocation in AML.2017, Cytogenetic and genome research, 153(3) (3), 131 - 137, English, International magazineScientific journal
- A prospective study of the antiemetic effect of palonosetron in malignant lymphoma patients treated with the CHOP regimen.To identify strategies for reducing emesis induced by the CHOP regimen, which includes high-dose steroids, we prospectively evaluated the efficacy of palonosetron in Japanese patients. Palonosetron was administered at a dose of 0.75 mg via intravenous injection over 30 min before chemotherapy on day 1. Patients kept diaries of chemotherapy-induced nausea and vomiting (CINV) incidence from the start of chemotherapy until 168 h afterwards, in which they documented the occurrence and severity of nausea, vomiting, anorexia, and the use of rescue medication. The primary endpoint was the overall occurrence rate of nausea, vomiting, and anorexia; these rates were 56, 12, and 62 %, respectively, including all grades. The rates and severity of symptoms tended to worsen 120-168 h after completing oral prednisolone. We defined complete response (CR) as no vomiting and no use of rescue therapy. The CR rates of post palonosetron 0.75 mg treatment in the acute (0-24 h), delayed (24-168 h), and overall phases (0-168 h) were 86, 66, and 62 %, respectively. Antiemetic strategies of CHOP regimen for day 6 and, thereafter, should be investigated.Dec. 2016, International journal of hematology, 104(6) (6), 682 - 691, English, Domestic magazineScientific journal
