    英語, 研究論文(学術雑誌), Acute myeloid leukemia (AML) is an aggressive hematological malignancy with genetic alterations. The FMS-like tyrosine kinase 3 (FLT3) gene is frequently mutated in adult de novo AML, with two types of mutations: internal tandem duplication (ITD) and point mutations in the tyrosine kinase domain. This study aimed to investigate the impact of FLT3 inhibitors and hematopoietic cell transplantation (HCT) on survival outcomes in patients with FLT3-ITD AML in a real-world setting. We retrospectively analyzed 139 patients with FLT3-ITD-positive AML between 2012 and 2021. The median age was 63 years. In the propensity score-matched cohort, FLT3 inhibitors improved overall survival (OS) compared with patients treated without FLT3 inhibitors (3-year OS: 33.7% vs. 25.8%, p = 0.021). Patients who underwent HCT had superior outcomes to those without HCT (3-year OS: 45.3% vs. 2.2%, p < 0.0001). The combination of FLT3 inhibitors and HCT resulted in the highest OS and relapse-free survival (RFS) rates (3-year OS: 62.4%; 3-year RFS: 44.4%). Disease status before transplantation did not predict the prognosis, but use of FLT3 inhibitors increased survival in patients without complete remission before HCT. These results demonstrate the clinical impact of FLT3 inhibitors on survival outcomes in patients with FLT3-ITD-positive AML, particularly when combined with HCT. FLT3 inhibitors can improve the prognosis of AML with FLT3 mutations, especially in patients who undergo HCT.

    英語, 研究論文(学術雑誌), Adult T-cell leukemia/lymphoma (ATLL) is an aggressive T-cell malignancy with a poor prognosis and limited treatment options. Programmed cell death ligand 1(PD-L1) is recognized to be involved in the pathobiology of ATLL. However, what molecules control PD-L1 expression and whether genetic or pharmacological intervention might modify PD-L1 expression in ATLL cells is still unknown. In order to comprehend the regulatory mechanisms of PD-L1 expression in ATLL cells, we performed unbiased genome-wide clustered regularly interspaced short palindromic repeat (CRISPR) screening in this work. In ATLL cells, we discovered that the neddylation-associated genes NEDD8, NAE1, UBA3, and CUL3 negatively regulated PD-L1 expression while STAT3 positively did so in ATLL cells. We verified, in line with the genetic results, that treatment with the JAK1/2 inhibitor ruxolitinib or the neddylation pathway inhibitor pevonedistat resulted in a decrease in PD-L1 expression in ATLL cells or an increase in it. It is significant that these results held true regardless of whether ATLL cells had the PD-L1 3' structural variant, a known genetic anomaly that promotes PD-L1 overexpression in certain primary ATLL patients. Pevonedistat alone showed cytotoxicity for ATLL cells, but compared to each single modality, pevonedistat improved the cytotoxic effects of the anti-PD-L1 monoclonal antibody Avelumab and chimeric antigen receptor T-cells targeting PD-L1 in vitro. As a result, our work provided insight into a portion of the complex regulatory mechanisms governing PD-L1 expression in ATLL cells and demonstrated the in vitro preliminary preclinical efficacy of PD-L1-directed immunotherapies by using pevonedistat to upregulate PD-L1 in ATLL cells.

    英語, 研究論文(学術雑誌), BACKGROUND: Pegfilgrastim, a long-acting form of granulocyte-colony stimulating factor, with a convenient single-injection dosage, is being investigated for peripheral blood stem cell (PBSC) mobilization in healthy volunteers. However, data on the adequate dose of pegfilgrastim for PBSC mobilization are limited. This phase 2, single-arm study evaluated the efficacy and safety of pegfilgrastim for PBSC mobilization in healthy volunteers. METHODS: The study comprised 2 phases: pilot (steps 1-3, dose escalation, a single subcutaneous dose of 3.6, 7.2, and 10.8 mg pegfilgrastim, respectively) and evaluation (step 4, efficacy and safety assessments). The primary endpoint was the proportion of subjects who achieved mobilization of ≥20 × 106/L cluster of differentiation 34 positive (CD34+) cells. RESULTS: Thirty-five subjects (6 each in steps 1 and 2 and 23 in step 4) were included. In the pilot phase, step 3 with a 10.8 mg dose was not conducted due to favorable outcomes in step 2 (desired CD34+ cell count), at 7.2 mg pegfilgrastim, which was identified as the optimal dose for the evaluation phase. In the evaluation phase, successful CD34+ mobilization was achieved in all 23 subjects. The mean peripheral blood CD34+ cells count peaked on day 5. Back pain, thrombocytopenia, transient elevations of alkaline phosphatase, and lactate dehydrogenase were the most common adverse events. All adverse events were mild, and none led to study discontinuation. CONCLUSIONS: A single-dose pegfilgrastim successfully mobilized an optimal number of CD34+ cells and was well tolerated. Pegfilgrastim could be an alternative option for PBSC mobilization in healthy volunteers. The trial was registered at www.clinicaltrials.gov (NCT03993639).

    研究論文(学術雑誌), Abstract

    Background

    Integrase strand transfer inhibitors (INSTIs) are recommended as first-line ART for people living with HIV (PLWH) in most guidelines. The INSTI-resistance-associated mutation E157Q, a highly prevalent (2%–5%) polymorphism of the HIV-1 (human immunodeficiency virus type 1) integrase gene, has limited data on optimal first-line ART regimens. We assessed the virological outcomes of various first-line ART regimens in PLWH with E157Q in real-world settings.

    Methods

    A multicentre retrospective observational study was conducted on PLWH who underwent integrase genotypic drug-resistance testing before ART initiation between 2008 and 2019 and were found to have E157Q. Viral suppression (&lt;50 copies/mL) rate at 24 and 48 weeks, time to viral suppression and time to viral rebound (≥100 copies/mL) were compared among the first-line ART regimens.

    Results

    E157Q was detected in 167 (4.1%) of 4043 ART-naïve PLWH. Among them, 144 had available clinical data after ART initiation with a median follow-up of 1888 days. Forty-five started protease inhibitors + 2 NRTIs (PI group), 33 started first-generation INSTI (raltegravir or elvitegravir/cobicistat) + 2 NRTIs (INSTI-1 group), 58 started once-daily second-generation INSTI (dolutegravir or bictegravir) + 2 NRTIs (INSTI-2 group) and eight started other regimens. In the multivariate analysis, the INSTI-2 group showed similar or favourable outcomes compared with the PI group for viral suppression rates, time to viral suppression and time to viral rebound. Two cases in the INSTI-1 group experienced virological failure.

    Conclusions

    The general guideline recommendation of second-generation INSTI-based first-line ART for most PLWH is also applicable to PLWH harbouring E157Q.

    英語, 研究論文(学術雑誌), IKZF1 deletion is a recurrent genomic alteration in B-cell acute lymphoblastic leukemia (B-ALL) and is divided into dominant-negative (DN) and loss of function (LOF) deletions. The prognostic impact of each deletion has not been fully elucidated. We retrospectively analyzed 117 patients with adult B-ALL including 60 patients with BCR::ABL1-positive B-ALL and 57 patients with BCR::ABL1-negative B-ALL by the fluorescence in situ hybridization (FISH) method for IKZF1 deletion and multiplex PCR for the 4 most common IKZF1 deletions (∆4-7, ∆2-7, ∆2-8, and ∆4-8). Samples, in which IKZF1 deletion was detected by FISH but a specific type of deletion was not identified by the PCR, were categorized as "other." Patients were classified into a DN group that had at least 1 allele of ∆4-7 (n = 23), LOF and other group (n = 40), and wildtype group (n = 54). DN type IKZF1 deletions were found in 33.3% of BCR::ABL1-positive cases and 5.2% of BCR::ABL1-negative cases. LOF and other type IKZF1 deletions were found in 43.4% of BCR::ABL1-positive cases and 24.6% of BCR::ABL1-negative cases. Patients with the DN group showed significantly higher overall survival (OS) than that of the LOF and other and WT groups (P = 0.011). Multivariate analysis including age, WBC counts, complex karyotype, and DN type IKZF1 deletion showed that the DN type of IKZF1 deletion (HR = 0.22, P = 0.013) had a positive impact and age ≥ 65 (HR = 1.92, P = 0.029) had a negative impact on OS. The prognostic impact of IKZF1 deletion depends on the type of deletion and DN type of IKZF1 deletion showed better prognosis in adult B-ALL patients.Clinical trial registration This study was part of a prospective observational study (Hokkaido Leukemia Net, UMIN000048611). It was conducted in compliance with ethical principles based on the Helsinki Declaration and was approved by the institutional review board of Hokkaido University Hospital (#015-0344).

    英語, 研究論文(学術雑誌), Calcineurin inhibitor-based graft-versus-host disease (GVHD) prophylaxis is standard in allogeneic hematopoietic stem cell transplantation (HCT) but fails to induce long-term tolerance without chronic GVHD in a considerable number of patients. In this study, we addressed this long-standing question in mouse models of HCT. After HCT, alloreactive donor T cells rapidly differentiated into PD-1+ TIGIT+ terminally exhausted T cells (terminal-Tex). GVHD prophylaxis with cyclosporine (CSP) suppressed donor T-cell expression of TOX, a master regulator to promote differentiation of transitory exhausted T cells (transitory-Tex), expressing both inhibitory receptors and effector molecules, into terminal-Tex, and inhibited tolerance induction. Adoptive transfer of transitory-Tex, but not terminal-Tex, into secondary recipients developed chronic GVHD. Transitory-Tex maintained alloreactivity and thus PD-1 blockade restored graft-versus-leukemia (GVL) activity of transitory-Tex, not terminal-Tex. In conclusion, CSP inhibits tolerance induction by suppressing the terminal exhaustion of donor T cells, while maintaining GVL effects to suppress leukemia relapse.

    英語, 研究論文(学術雑誌), Epstein-Barr virus-associated smooth muscle tumor (EBV-SMT) is a rare mesenchymal tumor which occurs in immunocompromised patients. The immune status is an important factor in the treatment of EBV-SMTs, but the efficacy of antiretroviral therapy (ART) is not elucidated in acquired immune deficiency syndrome (AIDS) related EBV-SMTs. Here, we report the first successful case of a 29-year-old man with hepatic AIDS related EBV-SMT treated with ART solely. Positron emission tomography scan was useful for the evaluation of disease status. Recent advances in ART that enables to restore patient's immune status rapidly may change the treatment strategy in AIDS related EBV-SMT.

    英語, 研究論文(学術雑誌), BACKGROUND: Human immunodeficiency virus (HIV) and hepatitis C virus (HCV) coinfection through unheated blood product for hemophilia caused in early 1980s has been significantly serious problem in Japan. After the development of HIV treatment in 1990s, HCV-related hepatocellular carcinoma (HCC) has been one of the most significant problem in these population. Treatment choices for HCC might be limited in hemophilia patients because of their bleeding tendency. The aim of this study was to elucidate the treatment choices and outcome of HCC in hemophilic patients coinfected with HIV/HCV due to contaminated blood products. METHODS: We asked 444 Japanese centers that specialize in treating HIV patients for participation, whether they have HIV/HCV coinfected cases with HCC, and the patient characteristics, treatments for HCC and survival after treatments were retrospectively reviewed according to each institutional medical records. RESULTS: Of 444 centers, 139 centers (31%) responded to the first query, and 8 centers (1.8%) ultimately provided 26 cases of HCC in coinfected hemophilic patients, diagnosed between December 1999 and December 2017. All 26 were male hemophilic patients, with a median age at HCC diagnosis of 49 (range, 34-73) years. Thirteen cases (50%) were HCV-RNA positive, and 14 cases (54%) had a solitary tumor. Even in the cases of Child-Pugh grade A, only 1 case underwent resection, and 18 cases (69%) did not receive the standard treatment recommended by the Japanese Society of Hepatology. CONCLUSIONS: Hemophilic HCC patients with HIV/HCV coinfection may not routinely receive standard treatment due to their bleeding tendency and several complications related to HIV/HCV coinfection.

    英語, 研究論文(学術雑誌), Adult T-cell leukemia/lymphoma (ATLL) is an aggressive T-cell malignancy with a poor prognosis with current therapy. Here we report genome-wide CRISPR-Cas9 screening of ATLL models, which identified CDK6, CCND2, BATF3, JUNB, STAT3, and IL10RB as genes that are essential for the proliferation and/or survival of ATLL cells. As a single agent, the CDK6 inhibitor palbociclib induced cell cycle arrest and apoptosis in ATLL models with wild type TP53. ATLL models that had inactivated TP53 genetically were relatively resistant to palbociclib owing to compensatory CDK2 activity, and this resistance could be reversed by APR-246, a small molecule activator of mutant TP53. The CRISPR-Cas9 screen further highlighted the dependence of ATLL cells on mTORC1 signaling. Treatment of ATLL cells with palbociclib in combination with mTORC1 inhibitors was synergistically toxic irrespective of the TP53 status. This work defines CDK6 as a novel therapeutic target for ATLL and supports the clinical evaluation of palbociclib in combination with mTORC1 inhibitors in this recalcitrant malignancy.

    英語, 研究論文(学術雑誌), HIV/HCV co-infection from blood products for hemophilia has been a social problem in Japan. Liver transplantation (LT) is an important treatment option for hepatic failure and cirrhosis of the liver in co-infected patients, and appropriate indications for LT, especially organ form deceased donors, are required by society. The aim is to propose priority status for the waiting list for deceased donor (DD) LT in HIV/HCV co-infected patients in Japan based on medical and scientific considerations. Since 2009, we have been working on the subject in research projects under grants-in-aid for health and labour sciences research on AIDS measures provided by the Ministry of Health, Labour and Welfare (the Kanematsu project and Eguchi project). Our research showed that hepatic fibrosis is advanced in HIV/HCV co-infected Japanese patients, especially those with hemophilia who became infected from blood products at a faster rate than HCV mono-infected patients. In addition, those patients who developed portal hypertension had a poor prognosis at a young age. The results of our research contributed to increasing the priority score of those patients on the deceased donor liver transplantation (DDLT) waiting list in 2013 and to establishing a scoring system for DDLT corresponding to the Model for End-stage Liver disease (MELD) score in 2019. This paper introduces changes in priority and the current state of priority of the DDLT waiting list for HIV/HCV co-infected patients in Japan.

    英語, 研究論文(学術雑誌), Antithymocyte globulin (ATG) reduces severe acute and chronic graft-versus-host disease (GVHD) in allogeneic peripheral blood stem cell transplantation (PBSCT). However, risk factors for severe acute GVHD in PBSCT using ATG remain to be determined. We conducted a single-center, retrospective study to analyze the association of acute GVHD requiring systemic corticosteroid (SC-aGVHD) with absolute lymphocyte counts (ALC) before the administration of ATG or conditioning in 53 patients with HLA-matched PBSCT using low-dose thymoglobulin (2 mg/kg) after myeloablative conditioning. The cumulative incidence of SC-aGVHD was 17.0% and ALC before ATG were significantly higher in patients with SC-aGVHD compared to that in patients without it (median, 0.15 × 109/L vs 0.06 × 109/L, P = 0.047). The cumulative incidence of SC-aGVHD was significantly higher in patients with high ALC before ATG (≥ 0.15 × 109/L) than in those with low ALC (38.5% vs 10.0%, P = 0.016). Non-relapse mortality (NRM) was also significantly higher in the high ALC before ATG group than the low ALC before ATG group (2-year NRM: 23.9% vs 6.0%, P = 0.048), leading to worse survival (2-year overall survival: 69.2% vs 83.5%, P = 0.039). Our study suggested that high ALC before ATG is a risk factor for SC-aGVHD.

    日本語, 研究論文(学術雑誌), A 25-year-old male with a medical history of stress polycythemia was admitted to a previous hospital for leukocytosis, anemia, and thrombocytopenia. Bone marrow examination revealed left-shifted myeloid hyperplasia without increased blasts and normal male karyotype. No mutations of JAK2, V617F, and colony-stimulating factor 3 receptor gene (CSF3R) were detected. Fluorescence in-situ hybridization for BCR-ABL1 and FIP1L1-PDGFRA were negative. Based on these findings, a diagnosis of an unclassifiable myeloproliferative neoplasm was made, and he was started on hydroxyurea treatment. He was referred to our hospital in April 2016 for transfusion dependence. Bone marrow examination performed at our hospital revealed granulocytic dysplasia and CSF3R T618I was detected. After induction therapy, CSF3R T618I became undetectable, and he went on to undergo allogeneic stem cell transplantation in October 2016. He has been in remission for >4 years posttransplantation. CSF3R T618I is one of the genes responsible for chronic neutrophilic leukemia and atypical chronic myeloid leukemia, suggesting its involvement in the pathogenesis of this case.

    英語, 研究論文(学術雑誌), Entamoeba histolytica infection is an increasingly common sexually transmitted infection in Japan. Currently, stool ova and parasite examination (O&P) is the only approved diagnostic method. Here, we assessed the utility of the commercially available rapid antigen detection test (Quik Chek) for E. histolytica A multicenter cross-sectional study was conducted. Stool samples that had been submitted for O&P were included. The samples were subjected to both Quik Chek and PCR, and the Quik Chek results were assessed in comparison with PCR as the reference standard. E. histolytica infection was confirmed in 5.8% (38/657) of the samples and comprised 20 diarrheal and 18 nondiarrheal cases. The overall sensitivity and specificity of Quik Chek were 44.7% (95% confidence interval, 30.1 to 60.3) and 99.8% (99.1 to 100), respectively. The sensitivity of Quik Chek was higher for diarrheal cases (60.0%) than for nondiarrheal cases (27.8%). Furthermore, the combined use of Quik Chek with O&P increased the sensitivity (78.9%), especially for diarrheal cases (up to 90%). The E. histolytica burden assessed by quantitative PCR was similar between Quik Chek-positive and -negative samples. The Quik Chek assay sensitivity was lower for cyst-containing stools than for trophozoite-containing stools, although it was shown that cultured E. histolytica clinical strains from Quik Chek-negative cyst-containing stools exhibited antigenicity in vitro The present study confirmed the high specificity of Quik Chek for E. histolytica infection. Combined use with O&P increased the sensitivity of detection, facilitating the use of Quik Chek in point-of-care settings in nonendemic situations.

    英語, 研究論文(学術雑誌), Tirabrutinib is a second-generation Bruton's tyrosine kinase inhibitor with greater selectivity than ibrutinib. Here, we conducted a multicenter, phase II study of tirabrutinib in patients with treatment-naïve (Cohort A) or with relapsed/refractory (Cohort B) Waldenström's macroglobulinemia (WM). Patients were treated with tirabrutinib 480 mg once daily. The primary endpoint was major response rate (MRR; ≥ partial response). Secondary endpoints included overall response rate (ORR; ≥ minor response), time to major response (TTMR), progression-free survival (PFS), overall survival (OS), and safety. In total, 27 patients (18 in Cohort A; 9 in Cohort B) were enrolled. The median age was 71 y, and the median serum immunoglobulin M level was 3600 mg/dL. Among the patients, 96.2% had the MYD88L265P mutation. MRR and ORR were 88.9% and 96.3%, respectively (Cohort A: MRR, 88.9%; ORR, 94.4%; Cohort B: MRR, 88.9%; ORR, 100%). Median TTMR was 1.87 mo. PFS and OS were not reached with a median follow-up of 6.5 and 8.3 mo for Cohorts A and B, respectively. The most common adverse events (AEs) were rash (44.4%), neutropenia (25.9%), and leukopenia (22.2%), with most AEs classified as grade 1 or 2. Grade ≥ 3 AEs included neutropenia (11.1%), lymphopenia (11.1%), and leukopenia (7.4%). No grade 5 AEs were noted. All bleeding events were grade 1; none were associated with drug-related atrial fibrillation or hypertension. Although the follow-up duration was relatively short, the study met the primary endpoint. Therefore, tirabrutinib monotherapy is considered to be highly effective for both untreated and relapsed/refractory WM with a manageable safety profile. (JapicCTI-173646).

    英語, 研究論文(学術雑誌), BACKGROUND: Pegfilgrastim has equivalent efficacy to daily granulocyte colony-stimulating factor (G-CSF) in enhancing neutrophil recovery after chemotherapy, but data on its use for peripheral blood stem cell (PBSC) mobilization are limited. We evaluated the safety and efficacy of CD34+ PBSC mobilization by low-dose (3.6 mg) pegfilgrastim after chemotherapy in patients with malignant lymphoma. STUDY DESIGN AND METHODS: Twenty patients with malignant lymphoma were enrolled in this study. Cytotoxic chemotherapy was started on day 1, and 3.6 mg of pegfilgrastim was subcutaneously administered on day 7. CD34+ cells were counted in the peripheral blood daily from days 11 to 14 using a flow cytometric analysis. RESULTS: In 19 of the 20 patients (95%), the CD34+ cell counts in the peripheral blood exceeded 10 × 106/L, with a mean value of 20.3 on day 11, 38.0 on day 12, 40.3 on day 13, and 40.1 on day 14. Older age was associated with lower maximum CD34+ cell mobilization. The most frequent adverse events associated with pegfilgrastim were back pain, nausea, appetite loss, and lactate dehydrogenase elevation. CONCLUSION: Our data indicated that a single dose of 3.6 mg pegfilgrastim on day 7 after chemotherapy safely and effectively mobilized CD34+ cells.

    英語, 研究論文(学術雑誌), Systemic chronic active Epstein-Barr virus infection (sCAEBV) was defined as a T- or NK-cell neoplasm in the 2017 World Health Organization (WHO) classification. To clarify the clinical features of sCAEBV under this classification and review the effects of chemotherapy, we performed a nationwide survey in Japan from 2016 through 2018 of patients with sCAEBV newly diagnosed from January 2003 through March 2016. One hundred cases were evaluated. The patients were aged 1 to 78 years (median, 21) and included 53 males and 47 females. Spontaneous regression was not observed in patients with active disease. In the childhood-onset group (age, <9 years), 78% of the patients were male. In contrast, 85% of the patients in the elderly-onset group (age, >45 years) were female. The prognosis of the childhood-onset group was better than those of the adolescent/adult- and elderly-onset groups. The main chemotherapies used were a combination of cyclosporine A, steroids, and etoposide (cooling therapy) in 52 cases and cyclophosphamide, doxorubicin, vincristine, and prednisolone (CHOP) in 45 cases. The rate of complete response (CR), defined as complete resolution of disease activity, was 17% for cooling therapy and 13% for CHOP. Virological CR was not observed. The 3-year overall survival rates in patients treated with chemotherapy only (n = 20), chemotherapy followed by allogeneic hematopoietic stem cell transplantation (allo-HSCT; n = 47), and allo-HSCT only (n = 12) were 0%, 65%, and 82%, respectively. Distinct characteristics were observed between childhood- and elderly-onset sCAEBV, and they appeared to be different disorders. Chemotherapy is currently insufficient to resolve disease activity and eradicate infected cells. The development of an effective treatment is urgently needed.

    英語, 研究論文(学術雑誌), We report the second case of deceased donor liver transplantation in a patient co-infected with human immunodeficiency virus (HIV) and hepatitis C virus (HCV) in Japan. A 48- year-old patient with hemophilia A was infected with HIV and HCV through a contaminated factor VIII concentrate in his childhood and developed cirrhosis and hepatocellular carcinoma. The patient was on the transplant list for a deceased donor liver. The patient had broad spectrum anti-HLA class I and II antibodies, which may have been due to repeated whole blood transfusions in the past. Catastrophic coagulopathy during the surgery was predicted because of the underlying hemophilic status and severe thrombocytopenia requiring HLA-matched platelet products, which are difficult to obtain quickly. To maintain adequate platelet counts(>5x104/ μl) while waiting liver transplantation, a thrombopoietin receptor agonist and rituximab were administered. During surgery, factor VIII concentrate was administered according to the previously planned protocol. Adequate hemostasis was obtained, and the operation was completed without uncontrollable coagulopathy. The postoperative course was uneventful, and the patient was discharged on postoperative day 41. Detailed planning is required for surgical patients with hemophilia and HIV/HCV cirrhosis, especially for those with a diverse spectrum of anti-HLA antibodies.

    英語, 研究論文(学術雑誌), Although a combination of calcineurin inhibitor and methotrexate (MTX) is used for graft-versus-host disease (GVHD) prophylaxis in umbilical cord blood transplantation (CBT), optimal dose of MTX for CBT remains to be determined.We conducted a retrospective study to evaluate the safety and efficacy of standard-dose MTX (St-MTX, 15 mg/m2 on day 1 and 10 mg/m2 on days 3 and 6) and mini-dose MTX (Mini-MTX, 5 mg/m2 on days 1, 3 and 6) for GVHD prophylaxis in patients who underwent single unit CBT against hematological malignancies.Thirty-two and 26 patients received St-MTX and Mini-MTX, respectively. Cumulative incidence of neutrophil engraftment was significantly higher in the Mini-MTX group than in the St-MTX group (88.5% vs 65.6%, P = 0.00448). Cumulative incidences of grade II to IV and grade III to IV of acute graft-versus-host disease (GVHD) were 34.4% and 6.2% in the St-MTX group, and 34.6% and 7.7% in the Mini-MTX group with no statistical significance. One-year non-relapse mortality (NRM) was significantly lower in the Mini-MTX group compared to the St-MTX group (31.2% vs 3.8%, P = 0.00938), whereas relapse rate was not different between the groups. Multivariate analysis also indicated that Mini-MTX significantly improved engraftment (HR, 0.5359; 95% CI, 0.3082 to 0.9318; P = 0.0270) and reduced NRM (HR, 0.117; 95% CI, 0.0151 to 0.9067; P = 0.040).Our study suggests that GVHD prophylaxis using Mini-MTX in CBT is feasible and associated with improvement of engraftment and reduction in NRM.

    Clin Transplant, 18, 11, e469, e479, 2018年11月, [査読有り], [国際誌]
    英語, 研究論文(学術雑誌), BACKGROUND: The prognostic effect of Wilms tumor 1 (WT1) expression at the diagnosis of acute myelogenous leukemia (AML) has been controversial. The aim of the present study was to determine the correlations of WT1 expression at the diagnosis of AML with established prognostic alterations. PATIENTS AND METHODS: We analyzed diagnostic bone marrow samples from 252 patients. WT1 expression, single nucleotide polymorphism (SNP) in the WT1 gene (rs16754), and Fms-like tyrosine kinase receptor-3 internal tandem duplication (FLT3-ITD) mutation were analyzed for all patients. The nucleophosmin 1 (NPM1) mutation and CCAAT/enhancer-binding protein-α (CEBPA) double mutation were analyzed for cytogenetically normal (CN)-AML. The KIT mutation was analyzed for core-binding factor AML. RESULTS: Within the cytogenetically favorable prognosis group, WT1 expression in AML with inv(16) or t(15;17) was significantly greater than that in AML with t(8;21). In cases with CN-AML, FLT3-ITD and NPM1 mutations both correlated with greater expression of WT1, and the CEBPA double mutation was related to lower WT1 expression. The existence of both FLT3-ITD and NPM1 mutations showed synergistically greater expression of WT1 in CN-AML. SNP in the WT1 gene (rs16754) was significantly associated with lower expression of WT1. The WT1 levels were not prognostic factors in the total cohort or any cytogenetic group or stratified by SNP status. CONCLUSION: Because WT1 expression has correlated with known prognostic factors, the prognostic effect of WT1 levels could be misunderstood depending on the distribution of the collaborative mutations in each cohort. We have concluded that the prognostic significance of WT1 at the diagnosis of AML is weak compared with the other established prognostic factors.

  • The association between the incidence of intestinal graft-vs-host disease and antibiotic use after allogeneic hematopoietic stem cell transplantation

    Clin Transplant, 32, 9, e13361, 2018年09月, [査読有り], [国際誌]
    英語, 研究論文(学術雑誌), Intestinal microbiota plays an important role in the regulation of allogeneic immune reaction after allogeneic hematopoietic stem cell transplantation (allo-SCT). Intestinal graft-vs-host disease (GVHD) is one of the major causes of mortality after allo-SCT and often complicated with intestinal dysbiosis. Recent studies suggest that antibiotic-induced dysbiosis is a risk factor for intestinal GVHD. We retrospectively evaluated the impacts of antibiotic use on the incidence of intestinal GVHD occurring before day 100 after allo-SCT. Among 213 patients who underwent allo-SCT, 200 patients achieving engraftment were analyzed. Antibiotics were classified into carbapenem, quinolone, penicillin, cephem, and glycopeptide. Among 128 patients who developed acute GVHD, intestinal GVHD developed in 36 patients. Patients with intestinal GVHD received significantly longer administration of carbapenem and glycopeptide compared to those without it in periengraftment period. In multivariate analysis, use of carbapenem for greater than 7 days was associated with an increased risk of intestinal GVHD. However, use of antibiotics for greater than 7 days was not associated with poor overall survival and high nonrelapse mortality. Long use of carbapenem in periengraftment period may be a risk for intestinal GVHD. Prospective studies are required to validate our findings.

    英語, 研究論文(学術雑誌), OBJECTIVES: The objective of this study is to elucidate the efficacy and safety of autologous haematopoietic stem cell transplantation (HSCT) for Japanese patients with systemic sclerosis (SSc). METHODS: A phase II clinical trial included SSc patients diagnosed within the last three years having at least one of the following clinical features: diffuse skin sclerosis with modified Rodman total thickness skin score (mRSS) ≥ 15, refractory digital ulcer or interstitial lung disease (ILD). HSCT were performed after conditioning using cyclophosphamide. RESULTS: Fourteen patients were enrolled and underwent HSCT. Median follow-up period was 137 months. Overall survival or event-free survival rate was 93% or 40% at 10 years, respectively. Eight patients (57%) achieved more than a 50% decrease in mRSS from baseline within six months after HSCT. Six patients (43%) required additional immunosuppressive treatments due to progression of diffuse skin sclerosis and/or ILD during follow-up period. Adverse events related to HSCT occurred in six patients (43%). Severe cardiomyopathy occurred in two patients, and one of them had a fatal course. CONCLUSION: HSCT is a feasible treatment bringing favourable results to more than half of our patients with SSc. Careful selection of the patients is essential for whom benefited from HSCT, considering the risk-benefit balance of the treatment.

    英語, 研究論文(学術雑誌), Endoscopic sphincterotomy (ES) is a standard procedure for bile duct stone removal. However, the safety of ES in patients with hemophilia remains unknown. We treated a 46-year-old man who had choledocholithiasis and severe hemophilia A with high-responding inhibitors during immune tolerance induction therapy. Since coagulation factor VIII inhibitors neutralize and inactivate endogenous and exogenous factor VIII, bleeding risk is higher in hemophilia A patients with inhibitors than in those without inhibitors. With adequate pre- and post-procedure monitoring of the clotting factor and supplemented clotting factor, the patient could safely undergo ES without bleeding complications. ES can be also an effective and safe first-line therapy for choledocholithiasis in patients with hemophilia and inhibitors under the condition of appropriate management.

    日本語, HIV陽性者に困難なく福祉サービス提供を行うために、「北海道福祉サービスネットワーク」を構築し、有効な手段を検討した。対象施設は、北海道内の福祉事業所(高齢者領域のサービス事業所、障がい領域のサービス事業所、領域を問わずサービス提供を行う保険外の事業所)とした。北海道ブロック各拠点病院HIV担当ソーシャルワーカーが、HIV陽性者に対して理解があると感じられる福祉事業所に登録依頼を行った。その結果、407件の登録が得られ、HIV陽性者へのサービス提供の経験のある福祉事業所の登録割合が92.3%と最も高かった。これは、サービス提供を行うことで、それまで未知であったHIV感染者に対する漠然とした不安や戸惑いが払拭されたものと考えられた。一方、登録を断った事業所については、施設長・責任者の賛同が得らないことを理由にあげられることから、施設長や責任者に対して、HIVに関する正しい知識を説明するなど、直接的にアプローチすることが有効と考えた。行政(北海道保健福祉部)から、ネットワークへの登録依頼文書を配布した987法人からは、2週間以内に17件の社会福祉法人、87件の福祉事業所からの登録が得られた。2週間という短期間で、多くの登録を得られたことは、行政との連携がきわめて有効と考えられた。

    英語, 研究論文(学術雑誌), The outcomes of cord blood transplantation with non-irradiated reduced-intensity conditioning for hematological malignancies need to be improved because of graft failure and delayed engraftment. Intrabone infusion of cord blood cells has the potential to resolve the problems. In this phase II study, 21 adult patients with hematological malignancy received intrabone transplantation of serological HLA-A, B, and DR ≥4/6 matched single cord blood with a median number of cryopreserved total nucleated cells of 2.7 × 107 /kg (range, 2.0-4.9 × 107 /kg) following non-irradiated fludarabine-based reduced-intensity conditioning. Short-term methotrexate and tacrolimus were given as graft-versus-host disease prophylaxis, and granulocyte colony-stimulating factor was given after transplantation. No severe adverse events related to intrabone injection were observed. The cumulative incidences of neutrophils ≥0.5 × 109 /L, reticulocytes ≥1%, and platelets ≥20 × 109 /L recoveries were 76.2%, 71.4%, and 76.2%, respectively, with median time to recoveries of 17, 28, and 32 days after transplantation, respectively. The probability of survival with neutrophil engraftment on day 60 was 71.4%, and overall survival at 1 year after transplantation was 52.4%. The incidences of grade II-IV and III-IV acute graft-versus-host disease were 44% and 19%, respectively, with no cases of chronic graft-versus-host disease. The present study showed the safety of direct intrabone infusion of cord blood. Further analysis is required to confirm the efficacy of intrabone single cord blood transplantation with non-irradiated reduced-intensity conditioning for adult patients with hematological malignancy. This study was registered with UMIN-CTR, number 000000865.

    研究論文(学術雑誌), We report a case of acute myeloid leukemia (AML) with two cytogenetically unrelated clones. The patient was a 45-year-old male who was diagnosed with acute monoblastic leukemia (AMoL). Initial G-band analysis showed 51,XY,+6,+8,inv(9)(p12q13)c,+11,+13,+19[12]/52,idem,+Y[8], but G-band analysis after induction therapy showed 45,XY,-7,inv(9)(p12q13)c[19]/46,XY,inv(9)(p12q13)c[1]. Retrospective FISH analysis revealed a cryptic monosomy 7 clone in the initial AML sample. The clone with multiple trisomies was eliminated after induction therapy and never recurred, but a clone with monosomy 7 was still detected in myelodysplastic marrow with a normal blast percentage. Both clones were successfully eliminated after related peripheral blood stem cell transplantation, but the patient died of relapsed AML with monosomy 7. We concluded that one clone was de novo AMoL with chromosome 6, 8, 11, 13, and 19 trisomy and that the other was acute myeloid leukemia with myelodysplasia-related changes (AML-MRC) with chromosome 7 monosomy showing different responses to chemotherapy. Simultaneous onset of cytogenetically unrelated hematological malignancies that each have a different disease status is a rare phenomenon but is important to diagnose for a correct understanding of the disease status and for establishing an appropriate treatment strategy.

    英語, 研究論文(学術雑誌), BACKGROUND: We investigated the pharmacokinetics of etoposide (ETP) to reduce the inter-individual variations of ETP concentrations in patients with acute leukemia who underwent allogeneic hematopoietic stem cell transplantation. We also carried out an in vivo study using rats to verify the dose adjustment. METHODS: This study included 20 adult patients. ETP was administered intravenously at a dose of 15 mg/kg once daily for 2 days (total dose: 30 mg/kg) combined with standard conditioning of cyclophosphamide and total body irradiation. In an in vivo study using rats, ETP was administered intravenously at a dose of 15 mg/kg or an adjusted dose. The ETP plasma concentration was determined by using HPLC. The pharmacokinetic parameters were estimated by using a 1-compartment model. RESULTS: The peak concentration (Cmax) of ETP and the area under the plasma concentration-time curve (AUC) of ETP differed greatly among patients (range of Cmax, 51.8 - 116.5 μg/mL; range of AUC, 870 - 2015 μg · h/mL). A significant relationship was found between Cmax and AUC (R = 0.85, P < 0.05). Distribution volume (Vd) was suggested to be one of the factors of inter-individual variation in plasma concentration of ETP in patients (range of Vd, 0.13 - 0.27 L/kg), and correlated with Alb and body weight (R = 0.56, P < 0.05; R = 0.40, P < 0.05 respectively). We predicted Vd of rats by body weight of rats (with normal albumin levels and renal function), and the dose of ETP was adjusted using predicted Vd. In the dose adjustment group, the target plasma ETP concentration was achieved and the variation of plasma ETP concentration was decreased. CONCLUSION: The results suggested that inter-individual variation of plasma concentration of ETP could be reduced by predicting Vd. Prediction of Vd is effective for reducing individual variation of ETP concentration and might enable a good therapeutic effect to be achieved.

    研究論文(学術雑誌), Human herpesvirus-6 (HHV-6) reactivation is sometimes observed in immunocompromised patients, especially after allogeneic stem cell transplantation. The complications of HHV-6 reactivation in this setting are mainly recognized as HHV-6 encephalitis. We herein report the case of a patient who developed HHV-6 pneumonitis after cord blood transplantation (CBT). A 35-year-old male underwent CBT for T-cell/myeloid mixed phenotype acute leukemia and achieved neutrophil engraftment on day 31. He had received foscarnet as prophylaxis for HHV-6 reactivation. A computed tomography (CT) scan to evaluate the leukemic tumor showed bilateral interstitial pneumonitis on day 33, although he had no respiratory symptoms. The findings of the CT scan were consistent with those of HHV-6 pneumonitis that were reported previously. HHV-6 DNA, but no other pathogens, was detected in his bronchoalveolar lavage (BAL) fluid. The patient was successfully treated with a therapeutic dose of foscarnet. This case indicates that performing a CT scan around the time of neutrophil engraftment can play an important role in detecting the early phase of HHV-6 pneumonia, and BAL should be considered if features consistent with HHV-6 pneumonitis are observed in patients with a risk of HHV-6 reactivation.

    英語, 研究論文(学術雑誌), BACKGROUND: Whether tenofovir nephrotoxicity is reversible after its withdrawal is unknown. Furthermore, there are no data on the viral efficacy of raltegravir (RAL) plus ritonavir-boosted Darunavir (DRV/r) in patients with suppressed viral load. METHODS: This multicenter, randomized trial compared renal function and viral efficacy in patients with suppressed viral load treated with RAL+DRV/r and ritonavir-boosted lopinavir (LPV/r) plus tenofovir/emtricitabine (TVD), who had been previously on LPV/r+TVD. The primary endpoint was the proportion of patients with >10% improvement in estimated glomerular filtration rate (eGFR) at 48 weeks calculated with Cockcroft-Gault equation. RESULTS: 58 randomized and treatment-exposed patients were analyzed (28 on RAL+DRV/r and 30 on LPV/r+TVD). Greater than 10% improvement in eGFR was noted in 6 (25%) out of 24 with RAL+DRV/r and 3 (11%) of 28 with LPV/r+TVD, and the difference was not statistically significant (p=0.272, 95% CI -0.067 to 0.354). Sensitivity analyses using three other equations for eGFR showed the same results. Urinary β2 microglobulin, a sensitive marker of tenofovir tubulopathy, significantly improved with RAL+DRV/r than with LPV/r+TVD (-271 versus -64 µg/gCr, p=0.026). Per protocol analysis showed that the HIV-RNA was <50 copies/mL at week 48 in all patients of both arms (24 in RAL+DRV and 29 in LPV/r+TVD). CONCLUSIONS: Switching LPV/r+TVD to RAL+DRV/r did not significantly increase the proportion of patients who showed >10% improvement in renal function among those with relatively preserved eGFR. However, the switch improved urinary β2 microglobulin, suggesting that discontinuation of TDF might be beneficial in the long-term. RAL+DRV/r showed favorable viral efficacy in patients with suppressed viral load.

    英語, Since the safety of folinic acid administration and its efficacy for reducing the toxicity of methotrexate (MTX) remain controversial, we assessed the effect of folinic acid administration after MTX treatment for GVHD prophylaxis on the incidence of oral mucositis and acute GVHD. We retrospectively analyzed data for 118 patients who had undergone allogeneic hematopoietic stem cell transplantation and had received MTX for GVHD prophylaxis. Multivariate analysis showed that systemic folinic acid administration significantly reduced the incidence of severe oral mucositis (OR = 0.13, 95%CI 0.04-0.73, P = 0.014). There was also a tendency for lower incidence of severe oral mucositis in patients who received folinic acid mouthwash (OR = 0.39, 95%CI 0.15-1.00, P = 0.051). No significant difference was observed in the incidence of acute GVHD between patients who received systemic folinic acid administration and those who did not (P = 0.88). Systemic folinic acid administration and mouthwash appear to be useful for reducing the incidence of severe oral mucositis in patients who have received allogeneic hematopoietic mucositis in patients who have received allogeneic hematopoietic stem cell transplantation using MTX as GVHD prophylaxis.

    英語, 研究論文(学術雑誌), Although bacterial infection is a major cause of death even after reduced-intensity conditioning (RIC) for allogeneic stem cell transplantation (SCT), little is known about the epidemiology and risk factors. The incidence of bacterial infection in 43 patients who received allogeneic bone marrow transplantation (BMT) using a RIC regimen was compared with that in 68 patients who received BMT using a myeloablative conditioning regimen, and risk factors for bacterial infection were identified. Before engraftment, incidences of febrile neutropenia (FN) and documented infections (DI) were significantly decreased in RIC patients (FN: 59.5% vs. 89.6%, P<0.01, DI: 4.8% vs. 17.9%, P<0.01). However, incidence of bacterial infection was significantly increased in RIC patients in the post-engraftment phase (53.8% vs. 11.1%, log-rank, P<0.01). Blood stream was the most frequent focus of infection in both groups. In multivariate analysis, RIC and acute graft-versus-host disease were revealed to be significant risk factors for bacterial infection in this phase. In summary, risk of bacterial infection after engraftment was significantly higher in RIC patients, although infection was decreased before engraftment, and we need to develop a RIC-specific strategy against bacterial infection after RIC SCT.
