We report herein a 59-year-old woman who developed S. commune rhinosinusitis after remission induction chemotherapy for her acute myeloid leukemia. No causative microorganisms were identified in the sinus lavage fluid culture, whereas nucleotide sequencing of the internal transcribed spacer region using endoscopic sinus biopsy specimen could confirm the pathogen as S. commune. Liposomal amphotericin B and voriconazole (VRCZ) treatment ameliorated both her clinical symptoms and laboratory findings. The patient was successfully treated with allogeneic stem cell transplantation, under continuous VRCZ administration, without aggravation of S. commune sinusitis. Molecular diagnosis and prompt intervention with suitable antifungal drugs may be crucial to manage this rare infectious complication..

Allo-HCT for ATL from HTLV-1 Antibody-Positive Donors, Biology of Blood and Marrow Transplantation, 10.1016/j.bbmt.2019.12.004, 26, 4, 718-722, 2020.04, Allogeneic hematopoietic stem cell transplantation (allo-HCT) is the only available curative treatment option for patients with aggressive adult T cell leukemia-lymphoma (ATL). Donor human T cell leukemia virus (HTLV) 1 seropositivity is a critical concern when choosing relative donors, as they are not usually recommended due solely to the occurrence of donor-derived ATL. A previous report suggested that allo-HCT with an HTLV-1-seropositive donor increased ATL-related mortality. We updated the risk assessment for choosing an HTLV-1-seropositive allo-HCT donor for ATL. Our current registry data, which include larger numbers of HTLV-1-seropositive donors and longer observation periods, revealed no significant difference in overall survival (hazard ratio [HR], 0.93; 95% confidence interval [CI], 0.70-1.24; P = .61) or cumulative incidence of either ATL-related (HR, 0.96; 95% CI, 0.64 to 1.45; P = .80) or non-ATL-related mortality (HR, 0.91; 95% CI, 0.61 to 1.37; P = .66). Similarly, when considering only patients with ATL in complete remission, there was no significant difference in overall survival (HR, 1.02; 95% CI, 0.70 to 1.49; P = .91) or cumulative incidence of either ATL-related (HR, 1.20; 95% CI, 0.66 to 2.20; P=0.54) or non-ATL-related mortality (HR, 0.86; 95% CI, 0.52-1.42; P = .66). These data indicate that selecting HTLV-1-seropositive donors might not be contraindicated for patients with ATL receiving allo-HCT if alternative donors are unavailable. Further risk assessment remains to be performed..

Although salvage SCTs can be performed with haploidentical donor (HID) or cord blood (CB), no study has compared the performances of these two sources. Using nationwide registration data, we compared the transplant outcomes of patients who developed GF and underwent salvage transplantation from HID (n = 129) and CB (n = 570) from 2007 to 2016. The HID group demonstrated better neutrophil recovery (79.7 vs. 52.5% at 30 days, P < 0.001). With a median follow-up of 3 years, both groups demonstrated similar overall survival (OS) and nonrelapse mortality (NRM; 1-year OS, 33.1 vs. 34.6% and 1-year NRM, 45.1 vs. 49.8% for the HID and CB groups). After adjustments for other covariates, OS did not differ in both groups. However, HID was associated with a lower NRM (hazard ratio, 0.71; P = 0.038) than CB. The incidence of acute graft-versus-host disease (GVHD)-related deaths was significantly higher in the HID group, although infection-related deaths were observed more frequently in the CB group. HID may be a promising salvage SCT option after GF due to its faster engraftment and low NRM..

From Basic Studies to Clinical Application, Frontiers in Immunology, 10.3389/fimmu.2019.03138, 10, 2020.01, Immune tolerance against alloantigens plays an important role in the success of clinical organ and allogeneic hematopoietic stem cell transplantation. The mechanisms of immune tolerance to alloantigens have gradually been elucidated over time. Although there have been numerous reports to date on the induction of tolerance to alloantigens, the establishment of mixed chimerism is well-known to be crucial in the induction and maintenance of immune tolerance for either of the methods. Since the early 1980s, the murine system of cyclophosphamide (Cy)-induced tolerance has also been examined extensively. The present review focuses on studies conducted on Cy-induced immune tolerance. Clinical data of patients with allogeneic transplantation suggest that the posttransplant Cy method to induce immune tolerance has been successfully translated from basic studies into clinical practice..

We analyzed the feasibility of SCT and risk factors associated with outcomes of PTCL-NOS and AITL patients to identify the potential clinical efficacy of SCT. We retrospectively analyzed the data of PTCL-NOS (n = 83) and AITL (n = 112) patients who received autologous (n = 10 and 16, respectively) or allogeneic (n = 12 and 4, respectively) SCT, or no SCT (n = 61 and 92, respectively) between 2008 and 2018. All PTCL-NOS and AITL diagnoses were reconfirmed by an experienced hematopathologist. Median age at PTCL-NOS and AITL diagnoses in the SCT group was younger than that in the no SCT group. Significant risk factors for lower overall survival were intermediate–high and high-risk international prognostic indexes in PTCL-NOS patients (P = 0.0052), and a > 2 modified prognostic index for T-cell lymphoma (P = 0.0079) and no SCT (P = 0.028) in AITL patients. Autologous or allogeneic SCT compared with no SCT in AITL patients resulted in 3-year overall survival of 68.6% and 100% vs. 57.2% (P = 0.018). Strategies should be developed to improve selection of PTCL-NOS and AITL patients suitable for SCT and/or additional novel therapies..

Median follow-up for survivors after undergoing allo-SCT was 72 months (range, 35–96 months). Eight patients received reduced-intensity conditioning (RIC) regimens, including three patients with fludarabine plus melphalan-based regimens and five patients with fludarabine plus busulfan-based regimens. The remaining 30 patients received myeloablative conditioning (MAC) regimens. Median ages in the RIC and MAC groups were 24 and 15 years, respectively. The 5-year overall survival rates in the RIC and MAC groups were 100% and 49%, respectively (P = 0.018). The 5-year event-free survival rates in the RIC and MAC groups were 88% and 43%, respectively (P = 0.039). In the RIC group, four of the eight patients showed residual disease at allo-SCT, but all eight patients survived with complete remission (CR), including one patient with relapse. This result suggests that allo-SCT using the RIC regimen may be effective for relapsed or refractory ALCL in children, adolescents, and young adults, even in non-CR cases..

We analyzed titers of antibodies against measles, rubella, mumps, and varicella zoster virus (VZV) from Japanese adult patients who underwent allogeneic HSCT (allo-HSCT) (n = 74), autologous HSCT (auto-HSCT) (n = 39), or chemotherapy (n = 93). The seropositive rates for measles, rubella, mumps, and VZV in allo-HSCT recipients were 20.2%, 36.4%, 5.4%, and 55.4%, respectively. These rates were equivalent to those in auto-HSCT recipients but were significantly lower than those in patients receiving chemotherapy. Antibody titers tended to gradually decrease with time. Twenty-nine allo-HSCT recipients and 8 auto-HSCT recipients received live attenuated vaccines against VPDs for which they tested seronegative. The titers of antibodies against measles, rubella, and mumps significantly increased after 2 shots of vaccine, and the seropositive rate increased up to 19%, 30%, and 27%, respectively. Three patients (8.1%) experienced mild adverse events, which resolved promptly, indicating safe administration of the live attenuated vaccines. In multivariate analysis, history of chronic graft-versus-host disease was significantly associated with high seropositivity for measles as well as high seroconversion rate for measles after vaccination. Live attenuated vaccines against VPDs were safely administered in seronegative adult HSCT recipients. A further observational study is crucial to evaluate the efficacy of vaccination in seronegative HSCT patients..

Clinicopathologic Features and Prognostic Factors, American Journal of Surgical Pathology, 10.1097/PAS.0000000000001271, 43, 7, 869-884, 2019.07, Methotrexate (MTX) carries a risk of lymphoproliferative disorders (LPDs), but MTX-associated LPDs (MTX-LPDs) can resolve spontaneously after MTX withdrawal. However, the precise clinicopathologic features of MTX-LPD remain unclear. We aimed to investigate the clinicopathologic characteristics, outcomes, and prognostic factors for histologic types of MTX-LPD. Paraffin-embedded tissue samples of 219 patients with MTX-LPD were analyzed. In total, 30,33,106, and 26 had reactive lymphoid hyperplasia (RH), polymorphic-LPD (Poly-LPD), diffuse large B-cell lymphomas (DLBCLs), and classic Hodgkin lymphoma (CHL), respectively. The clinicopathologic features of RH, Poly-LPD, DLBCLs, and CHL were as follows: extranodal involvement: 13.8% (4/29), 36.4% (12/33), 69.5% (73/105), and 15.4% (4/26); Epstein-Barr virus encoded RNA positivity: 55.2% (16/29), 71.9% (23/32), 45.3% (48/106), and 76.9% (20/26); necrosis: 0% (0/29), 51.5% (17/33), 34.3% (36/105), and 12.0% (3/25); and Hodgkin Reed-Sternberg-like cells: 17.2% (5/29), 50% (14/28), and 19.8% (21/106). The median duration from MTX withdrawal to the time of disease regression was 10.4, 3.0, 4.2, and 2.7 months for RH, Poly-LPD, DLBCLs, and CHL. After MTX withdrawal, progression-free survival was the greatest for RH, followed by for Poly-LPD, DLBCL, and CHL (all P<0.05). Overall survival did not differ significantly between the groups. On univariate analysis, the predictive factors for progression-free survival included plasma cell infiltrate for CHL, eosinophil infiltrate, age above 70 years, and extensive necrosis for Poly-LPD, while they were Epstein-Barr virus encoded RNA positivity and International Prognostic Index risk for DLBCL on multivariate analysis. In conclusion, histologic categorization and histology-specific factors could be useful for predicting MTX-LPD progression after MTX withdrawal..

Defibrotide (DF) is the only drug internationally recommended for SOS treatment in Western countries. Recombinant human soluble thrombomodulin (rhTM), which is promising for the treatment of patients with disseminated intravascular coagulation, is also reported to be potentially effective for SOS. To clarify the safety and efficacy of DF and rhTM, we conducted a retrospective survey of these agents in Japan. Data from 65 patients who underwent allogeneic HSCT and received DF (n = 24) or rhTM (n = 41) for SOS treatment were collected. The complete response rates for SOS on day 100 were 50% and 54% in the DF and rhTM groups, respectively. The 100-day overall survival rates were 50% in the DF group, and 48% in the rhTM group. Several severe hemorrhagic adverse events were observed in one patient in the DF group and five patients in the rhTM group. The main causes of death were SOS-related death, and no patient died of direct adverse events of DF or rhTM. Our results suggest that rhTM, as well as DF, can be effective as a novel treatment option for SOS..

HCV-positive diffuse large B cell lymphoma (DLBCL) has been reported to clinically manifest in extranodal lesions (e.g., in the liver, spleen, and stomach). Here, we investigated HCV-positive and -negative primary splenic DLBCL (p-spDLBCL) and non-primary splenic DLBCL (ordinary DLBCL). Furthermore, to examine HCV lymphomagenesis, RNA in situ hybridization (ISH), RT-PCR (reverse-transcription polymerase chain reaction), and NS3 immunostaining of HCV viral nonstructural proteins were performed. HCV-positive p-spDLBCL patients presented fewer B symptoms (asymptomatic) and better performance status, with elevated presence of splenic macronodular lesions and more germinal center B cell (GCB) sub-group cases than HCV-negative p-spDLBCL patients. However, HCV-positive ordinary DLBCL patients were found to have more non-GCB sub-group cases than HCV-negative ordinary DLBCL patients. HCV-positive DLBCL patients showed 20.6% (7/34) NS3 positivity, 16.7% (1/6) HCV-RNA in situ positivity, and 22.2% (2/9) detection of HCV-RNA in tumor tissue by RT-PCR. Splenic samples were found to have a higher frequency of HCV detection than lymph node samples, thus suggesting that HCV may be closely related to lymphomagenesis, especially in splenic lymphoma..

To clarify which patients with ATLL are likely to benefit from these treatment options and to define patient populations for novel treatments, we performed a nationwide retrospective analysis of 252 Japanese patients who had relapsed ATLL after allo-HSCT. Some long-term survivors remained after tapering and withdrawal of immunosuppressive agents. Thirty-six patients who received donor lymphocyte infusion had a better overall survival (OS) in comparison to those who did not [hazard ratio (HR), 0.63; 95% confidence interval (CI), 0.43-0.93; P =.02], suggesting the efficacy of a graft-versus-ATLL (GvATLL) effect even after relapse. Multivariate analysis demonstrated that skin lesions at initial relapse of ATLL were independently associated with higher OS (HR, 0.41; 95% CI, 0.22-0.74; P =.003), indicating that the skin is a susceptible target organ of GvATLL. This study suggested that enhancement of a GvATLL effect is a potential therapeutic option for relapsed disease after allo-HSCT. Further investigations of incorporation of immune-based approaches with new molecular target drugs into the therapeutic options of patients with ATLL before and after transplantation are warranted..

a global, double-blind, randomised, phase 3 trial, The Lancet, 10.1016/S0140-6736(18)32984-2, 393, 10168, 229-240, 2019.01, Background: Based on the encouraging activity and manageable safety profile observed in a phase 1 study, the ECHELON-2 trial was initiated to compare the efficacy and safety of brentuximab vedotin, cyclophosphamide, doxorubicin, and prednisone (A+CHP) versus cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) for the treatment of CD30-positive peripheral T-cell lymphomas. Methods: ECHELON-2 is a double-blind, double-dummy, randomised, placebo-controlled, active-comparator phase 3 study. Eligible adults from 132 sites in 17 countries with previously untreated CD30-positive peripheral T-cell lymphomas (targeting 75% with systemic anaplastic large cell lymphoma) were randomly assigned 1:1 to receive either A+CHP or CHOP for six or eight 21-day cycles. Randomisation was stratified by histological subtype according to local pathology assessment and by international prognostic index score. All patients received cyclophosphamide 750 mg/m 2 and doxorubicin 50 mg/m 2 on day 1 of each cycle intravenously and prednisone 100 mg once daily on days 1 to 5 of each cycle orally, followed by either brentuximab vedotin 1·8 mg/kg and a placebo form of vincristine intravenously (A+CHP group) or vincristine 1·4 mg/m 2 and a placebo form of brentuximab vedotin intravenously (CHOP group) on day 1 of each cycle. The primary endpoint, progression-free survival according to blinded independent central review, was analysed by intent-to-treat. This trial is registered with ClinicalTrials.gov, number NCT01777152. Findings: Between Jan 24, 2013, and Nov 7, 2016, 601 patients assessed for eligibility, of whom 452 patients were enrolled and 226 were randomly assigned to both the A+CHP group and the CHOP group. Median progression-free survival was 48·2 months (95% CI 35·2–not evaluable) in the A+CHP group and 20·8 months (12·7–47·6) in the CHOP group (hazard ratio 0·71 [95% CI 0·54–0·93], p=0·0110). Adverse events, including incidence and severity of febrile neutropenia (41 [18%] patients in the A+CHP group and 33 [15%] in the CHOP group) and peripheral neuropathy (117 [52%] in the A+CHP group and 124 [55%] in the CHOP group), were similar between groups. Fatal adverse events occurred in seven (3%) patients in the A+CHP group and nine (4%) in the CHOP group. Interpretation: Front-line treatment with A+CHP is superior to CHOP for patients with CD30-positive peripheral T-cell lymphomas as shown by a significant improvement in progression-free survival and overall survival with a manageable safety profile.

the Japan Society for Hematopoietic Cell Transplantation, Bone Marrow Transplantation, 10.1038/s41409-019-0752-5, 2019.01, Reactivation of human herpesvirus (HHV)-6B is relatively common after allogeneic hematopoietic stem cell transplantation (HSCT) and HHV-6B diseases may consequently develop. Among them, HHV-6B encephalitis is a serious and often fatal complication. The aim of these clinical practice recommendations is to provide diagnostic and therapeutic guidance for HHV-6B encephalitis after allogeneic HSCT. In this evidence-based review, we critically evaluated data from the published literature. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology was used to assist in generating recommendations. We have summarized the findings that contribute to decision-making and we have provided our recommendations. In cases where rigorous clinical data are unavailable, recommendations have been developed in discussions with physicians who have relevant expertize..

A total of 40 patients with hematologic malignancy were eligible in this study. This study was performed in the Department of Hematology, Kyushu University Hospital, as a subgroup analysis from a nationwide, multicenter prospective cohort study conducted by the CINV Study Group of Japan. In the patients with hematological malignancy, the guideline compliance rate was 45 %. Five patients (22.7 %) experienced vomiting during the observation period after receiving non-guideline-consistent antiemetic prophylaxis, whereas no patient experienced vomiting after receiving guideline-consistent antiemetic prophylaxis. The study was not sufficiently powered to reach a statistical significance in its frequency of occurrence between the compliance and non-compliance groups. In the entire study period, 8 out of 40 patients required rescue medication, but there was no association between the status of compliance and the antiemetic guidelines. A total of 22 (55.0 %) patients achieved complete response, which was defined as no vomiting and no use of antiemetic rescue medication, during the study period. The rate of compliance with the prophylactic antiemetic treatment guidelines seemed to be low in patients with hematological malignancy, although the status of the guideline compliance did not always influence the antiemetic effects..

However, reports of favorable results using BU against lymphomas have recently emerged. This study sought to compare the effectiveness of BU and TBI regimens for SCT against lymphomas. We retrospectively analyzed 893 lymphoma patients who underwent primary SCT in Japan between 1980 and 2015. The median age of all patients was 18 years (range, 0–30 years) with 589 males, 303 females, and 1 patient whose sex was unknown. Overall survival (OS) was not different between those receiving BU and TBI (P = 0.672). OS in patients receiving autologous SCT was significantly better with BU over TBI regimens (P = 0.038), particularly in children (0–15 years) (P = 0.024). Conversely, OS in adolescents and young adults (AYAs; 16–30 years) receiving allogeneic SCT was significantly worse with BU over TBI regimens (P = 0.035). Overall, BU regiments had comparable effectiveness to TBI conditioning regimens, and, although less effective for AYAs with allogeneic SCT, were particularly more effective than TBI regimens for children who received autologous SCT..

It is crucial for all members of the health care team to monitor the effect of medicines on the patient to ensure the safety and efficacy of the chemotherapy. The present study prepared medication instruction sheets (MISs) on hematological malignancy and conducted a questionnaire survey to verify their usefulness among physicians, dentists, and nurses. MISs were prepared for 103 chemotherapy and 44 pretreatment regimens for hematopoietic stem cell transplantation in the Department of Hematology at Kyushu University Hospital. Eight questions were prepared to investigate whether MISs could help physicians, dentists, and nurses manage cancer chemotherapy more safely, effectively, and efficiently, as well as in the sharing of information. A total of 35 medical staff working in inpatient wards, including 8 physicians, 3 dentists, and 24 nurses, participated in the questionnaire survey. All of the staff responded to the questionnaire survey, which showed that the MISs were favorably accepted by the participants. There was no negative opinion on the management of chemotherapy using the MISs. The MIS was a useful tool for sharing information on cancer chemotherapy between patients and medical staff and for enabling efficient management, thereby improving the safety and efficacy of treatment..

Because these 2 complications cause similar sensory nerve–related symptoms, such as paresthesia, pruritus, and severe pain occurring around the engraftment, it can be difficult to differentially diagnose the 2 conditions. We retrospectively analyzed 435 recipients to distinguish clinical symptoms of these 2 complications. Twenty-four patients (5.5%) developed HHV6-associated encephalitis/myelitis; of these, 11 (2.5%) presented only with myelitis-related symptoms (HHV6-associated myelitis), which was confirmed by the detection of HHV6 DNA, and 8 (1.8%) had CIPS, with undetected HHV6 DNA. All patients with HHV6-associated myelitis or CIPS exhibited similar sensory nerve–related symptoms. Diagnostic images did not provide definite evidence specific for each disease. Symptoms of all patients with CIPS improved after switching to another immunosuppressant. Overall survival rate at 2 years for patients with HHV6-associated encephalitis/myelitis was significantly lower than that of CIPS (13.1% versus 29.2%; P =.049) or that of patients without HHV6-associated encephalitis/myelitis or CIPS (42.4%; P =.036), whereas there was no significant difference among the latter 2 groups (P =.889). The development of HHV6-associated encephalitis/myelitis but not CIPS was significantly associated with poor prognosis. Thus, transplant physicians should be aware that sensory nerve–related symptoms indicate early manifestations that might be correlated with reactivation of HHV6 or CIPS. Therefore, identification of HHV6 DNA is crucial for making a differential diagnosis and immediately starting appropriate treatments for each complication..

Genomic alteration of GNA13 was frequently observed in follicular lymphoma (FL). In this study, we examined 167 cases of FL by immunostaining of GNA13 using tissue microarray to evaluate the clinical significance. There were 26 GNA13-positive cases (15.6%) and 141 GNA13-negative cases (84.4%). GNA13-positive cases had a higher incidence of early progression of disease for which disease progression was recognized within 2 years compared with GNA13-negative cases (P=0.03). There were no significant differences in other clinicopathologic factors including histological grade, BCL2-IGH translocation, immunohistochemical phenotype, and Follicular Lymphoma International Prognostic Index. In addition, overall survival and progression-free survival were poorer in GNA13-positive cases than in GNA13-negative cases (P=0.009 and 0.005, respectively). In multivariate analysis, GNA13 positivity was found to be a poor prognostic factor for overall survival and progression-free survival. Thus, GNA13 protein expression was an independent prognostic factor and may affect disease progression in FL..

Here, we conducted a retrospective study to assess the morbidity, etiology, risk factors, and outcomes of BSI in the postengraftment period (PE-BSI) after allo-HSCT. Forty-three of 316 patients (13.6%) developed 57 PE-BSI episodes, in which 62 pathogens were isolated: Gram-positive bacteria, gram-negative bacteria, and fungi, respectively, accounted for 54.8%, 35.5%, and 9.7% of the isolates. Multivariate analysis revealed methylprednisolone use for graft-versus-host disease (GVHD) prophylaxis (odds ratio [OR], 6.49; 95% confidence interval [CI], 1.49 to 28.2; P =.013) and acute gastrointestinal GVHD (GI-GVHD) (OR, 8.82; 95% CI, 3.99 to 19.5; P <.0001) as risk factors for developing PE-BSI. This finding suggested that GI-GVHD increases the risk of bacterial translocation and subsequent septicemia. Moreover, among patients with GI-GVHD, insufficient response to corticosteroids, presumably related to an intestinal dysbiosis, significantly correlated with this complication. Patients with PE-BSI presented worse outcome compared with those without (3-year overall survival, 47.0% versus 18.6%; P <.001). Close microbiologic monitoring for BSIs and minimizing intestinal dysbiosis may be crucial to break the vicious cycle between GI-GVHD and bacteremia and to improve transplant outcomes especially in patients who require additional immunosuppressants..

Allogeneic hematopoietic stem-cell transplantation (allo-HSCT) is a curative treatment modality for ATL, and four factors, namely, age > 50 years, male recipient, lack of complete remission at transplantation, and transplantation of cord blood, were previously shown to be associated with poor survival. We retrospectively analyzed the outcome of 21 patients with ATL who had undergone allo-HSCT at our hospital during a 3-year period. Of 21 patients, all had at least one of the above risk factors, and 18 had two or more. With a median follow-up of 19.7 months for living patients, the 1- and 2-year overall survival (OS) rates after transplantation were 34% and 27%, respectively. All relapse/progression events occurred within 1 year after allo-HSCT, and the cumulative incidence of relapse/progression at 1 year after allo-HSCT was 46.9%. The 100-day and 1-year nonrelapse mortality (NRM) rates were 19% and 42%, respectively. No significant difference in OS was observed between myeloablative and reduced-intensity conditioning regimens. The 3-year OS (27%) of ATL patients who received allo-HSCT and who had at least one adverse factor was somewhat poorer than the 3-year OS of 33% identified in a nationwide study of allo-HSCT in ATL patients in Japan. The high relapse/progression and NRM rates are major problems to be solved to achieve better outcome..

Although multiple disease-stratification models, including the cell-of-origin or gene-expression profiling methods, have been proposed for this condition, their clinical significance remains unclear. To establish a clinically meaningful stratification model, we analyzed gene-expression signatures of tumors and tumor-infiltrating immune cells using the nCounter system, which enables accurate quantification of low abundance and/or highly fragmented transcripts. To do so, we assessed transcripts of 120 genes related to cancer or immune cells using tumor samples from 68 newly diagnosed PTCL-NOS patients and validated findings by immunofluorescence in tumor sections. We show that gene-expression signatures representing tumor-infiltrating immune cells, but not those of cancerous T cells, dictate patient clinical outcomes. Cases exhibiting both B-cell and dendritic cell (DC) signatures (BD subgroup) showed favorable clinical outcomes, whereas those exhibiting neither B-cell nor DC signatures (non-BD subgroup) showed extremely poor prognosis. Notably, half of the non-BD cases exhibited a macrophage signature, and macrophage infiltration was evident in those cases, as revealed by immunofluorescence. Importantly, tumor-infiltrating macrophages expressed the immune-checkpoint molecules programmed death ligand 1/2 and indoleamine 2, 3-dioxygenase 1 at high levels, suggesting that checkpoint inhibitors could serve as therapeutic options for patients in this subgroup. Our study identifies clinically distinct subgroups of PTCL-NOS and suggests a novel therapeutic strategy for 1 subgroup associated with a poor prognosis. Our data also suggest functional interactions between cancerous T cells and tumor-infiltrating immune cells potentially relevant to PTCL-NOS pathogenesis..

A Prospective Multicenter Trial with an Historical Control Group, Biology of Blood and Marrow Transplantation, 10.1016/j.bbmt.2018.02.008, 24, 6, 1264-1273, 2018.06, Cord blood transplantation (CBT) is a distinct risk factor for human herpesvirus-6 (HHV-6) reactivation and HHV-6 encephalitis. In a prospective multicenter trial we investigated the effects of prophylactic foscarnet (90 mg/kg i.v. infusion from days 7 to 27 after CBT) on the occurrence of HHV-6 reactivation, HHV-6 encephalitis, and acute graft-versus-host disease (aGVHD) in CBT recipients. Between 2014 and 2016, 57 patients were included in a foscarnet-prophylaxis group. Outcomes were compared with an historical control group who received CBT between 2010 and 2014 (standard-treatment group, n = 63). The cumulative incidence of high-level HHV-6 reactivation, defined as plasma HHV-6 DNA ≥ 104 copies/mL, at 60 days after CBT was significantly lower in the foscarnet-prophylaxis group than in the standard-treatment group (18.3% versus 57.3%, P <.001). Multivariate analysis revealed that myeloablative preconditioning and standard treatment were significant risk factors for high-level HHV-6 reactivation. The cumulative incidence of HHV-6 encephalitis at 60 days after CBT was not different between the groups (foscarnet-prophylaxis group, 12.4%; standard-treatment group, 4.9%; P =.14). The cumulative incidences of grades II to IV and grades III to IV aGVHD at 60 days after CBT were not different between the groups (grades II to IV aGVHD: foscarnet-prophylaxis group, 42.0%; standard-treatment group, 40.5%; P =.96; grades III to IV aGVHD: foscarnet-prophylaxis group, 14.5%; standard-treatment group, 14.5%; P = 1.00). In the setting of this study foscarnet significantly suppressed systemic HHV-6 reactivation in CBT recipients but failed to prevent the development of HHV-6 encephalitis. Suppression of HHV-6 reactivation by foscarnet did not show any effects against the incidence of aGVHD..

Adult patients with chronic active epstein-barr virus infection-like features, Haematologica, 10.3324/haematol.2017.174177, 103, 6, 1018-1028, 2018.06, The characteristics of adult patients with chronic active Epstein-Barr virus infection are poorly recognized, hindering early diagnosis and an improved prognosis. We studied 54 patients with adult-onset chronic active Epstein-Barr virus infection diagnosed between 2005 and 2015. Adult onset was defined as an estimated age of onset of 15 years or older. To characterize the clinical features of these adults, we compared them to those of 75 pediatric cases (esti-mated age of onset <15 years). We compared the prognosis of adult-onset chronic active Epstein-Barr virus infection with that of patients with nasal-type (n=37) and non-nasal-type (n=45) extranodal NK/T-cell lymphoma. The median estimated age of onset of these lymphomas was 39 years (range, 16–86 years). Compared to patients with pediatric-onset disease, those in whom the chronic active Epstein-Barr virus infection developed in adulthood had a significantly decreased incidence of fever (P=0.005), but greater frequency of skin lesions (P<0.001). Moreover, hypersensitivity to mosquito bites and the occurrence of hydroa vacciniforme were less frequent in patients with adult-onset disease (P<0.001 and P=0.0238, respectively). Thrombocytopenia, high Epstein-Barr virus nuclear antigen antibody titer, and the presence of hemophagocytic syndrome were associated with a poor prognosis (P=0.0087, P=0.0236, and P=0.0149, respective-ly). Allogeneic hematopoietic stem cell transplantation may improve survival (P=0.0289). Compared to pediatric-onset chronic active Epstein-Barr virus infection and extranodal NK/T-cell lymphoma, adult-onset chronic active Epstein-Barr virus infection had a poorer prognosis (P<0.001 and P=0.0484, respectively). Chronic active Epstein-Barr virus infection can develop in a wide age range, with clinical differences between adult-onset and pediatric-onset disease. Adult-onset chronic active Epstein-Barr virus infection is a disease with a poor prognosis. Further research will be needed..

Several scoring systems (HCT-specific comorbidity index [HCT-CI]/modified European Group for Blood and Marrow Transplantation risk score [mEBMT]) have been adopted to predict HCT outcomes in other hematologic malignancies. We retrospectively evaluated HCT-CI and mEBMT to predict nonrelapse mortality (NRM) in 824 ATL patients registered in the Japan Society for Hematopoietic Cell Transplantation TRUMP database, from 2008 until 2013. A higher HCT-CI was associated with greater NRM when comparing HCT-CI 0 versus HCT-CI 1 to 3 and HCT-CI 0 versus HCT-CI ≥ 4. A higher mEBMT score was not associated with higher NRM when comparing mEBMT 0 to 3 with 4 to 6. Because ATL patients are older and consequently at risk of additional complications, we developed an optimized prognostic index for ATL (ATL-HCT-PI) using known risk factors: age, HCT-CI, and donor–recipient sex combination. The ATL-HCT-PI scores effectively predicted the 2-year NRM (22.0%, 27.7%, and 44.4%, respectively). Therefore, the newly developed ATL-HCT-PI, in combination with other risk factors, is more useful for predicting NRM in HCT for ATL patients..

Therefore, the rate of organ establishment has improved in transplantation. However, immunosuppressive agents generally suppress the function of T cells. Thus, opportunistic infections, such as cytomegalovirus infection, are still a major problem in kidney transplantation. Induction of specific tolerance to avoid immunosuppressive drug therapy after kidney transplantation is considered as the ultimate goal of transplantation. Various factors induce tolerance that involves establishment of hematopoietic chimerism and various cell subsets. In particular, we have carried out various studies regarding the cyclophosphamide-induced tolerance system. Tolerance is induced after establishment of hematopoietic chimerism after donor bone marrow transplantation. At the clinical stage, kidney transplantation before administration of cyclophosphamide after transfusion of bone marrow to create hematopoietic chimera is considered to be one of the most successful protocols. Furthermore, recent studies have shown the involvement of multiple populations of immune cells in preserving immunological tolerance and promoting long-term renal grafts. The present review focuses on how cyclophosphamide and other immune factors induce tolerance in kidney transplantation..

It is thought that HCV is involved in the onset of B-cell lymphoma. The clinicopathological characteristics of HCV-positive diffuse large B-cell lymphoma (DLBCL) and HCV-positive splenic marginal zone lymphoma (SMZL) are known, but there has been no report on HCV-positive follicular lymphoma (FL). In this study, the clinicopathological characteristics of HCV-positive FL were examined in 263 patients with FL who were classified into a HCV-positive group with HCV antibody and negative groups without one. The number of patients with HCV-positive FL and HCV-negative FL was 10 (3.8%) and 253 (96.2%), respectively. The patients with HCV-positive FL commonly had more than one region of lymphadenopathy, Ann Arbor stage III/IV, hemoglobin < 120 g/l, elevated lactate dehydrogenase level, and highrisk categorization of Follicular Lymphoma International Prognostic Index (FLIPI) than in patients with HCV-negative FL. Overall survival and progression-free survival were poorer in patients with HCV-positive FL than in those with HCV-negative FL (p < 0.0001 and 0.006, respectively). Also, multivariate analysis revealed that positive HCV antibody was a poor prognostic factor of OS. In conclusion, HCV-positive FL has unique clinical features and may have a great impact on the overall survival of affected patients..

When used in conjunction with posttransplantation cyclophosphamide (PTCY) for graft-versus-host disease prophylaxis, allo-HCT from an HLA haplo-identical donor yields promising outcomes for many diseases other than ATL. However, appropriate comparisons with other donor sources, especially cord blood and conventional HLA haplo-identical donors, are needed to validate the safety and efficacy of this modality. In this study, we retrospectively evaluated the outcome of allo-HCT without PTCY in patients with ATL registered in the Japan Society for Hematopoietic Cell Transplantation TRUMP database between 1985 and 2015. During that period, 46 patients received allo-HCT without PTCY and survivors were followed for a median of 2316.5 days (range: 220–3884 days). Although the estimated 1- and 5-year overall survival rates of the entire cohort were 34.5% and 17.7%, respectively, the cumulative 1- and 5-year non-ATL mortality rates of 41.3% and 55.8%, respectively, were high. The results of our study will serve as a platform for discussions of the safety and efficacy of haplo-HCT for future clinical trials in patients with ATL..

The Multinational Association for Supportive Care in Cancer (MASCC) developed the MASCC Antiemesis Tool (MAT) to facilitate recognition for CINV between patients and oncology specialists. In the present study, MAT and CTCAE were comparatively assessed in Japanese patients with hematological malignancies. A total of 61 patients were eligible for this study. The CTCAE data were collected from an electronic medical record system. The patients were asked to complete the Japanese version of MAT in the hospital, on the first and fourth days after the start of chemotherapy. The percentages of patients in whom nausea was completely controlled, with severity scores of zero, ranged from 70.5 to 82.0% for CTCAE and from 59.0 to 75.4% for MAT, during the first five days after the chemotherapy. The percentages of patients who had no vomiting ranged from 93.4 to 96.7% for CTCAE and from 90.2 to 98.4% for MAT. During the observation periods, the day-to-day response profiles of patients who received antiemetic treatment were comparable between CTCAE and MAT cohorts, and these two assessment tools showed good, positive correlations for nausea severity scores. The present study shows that the MAT is a useful tool for assessing the severity of CINV in patients with hematological malignancy, is comparable to CTCAE, and facilitates the identification of poor cancer care conditions by medical staff..

A total of 61 patients were eligible for this study. Before starting the bendamustine-based chemotherapy, granisetron or palonosetron were intravenously administered with or without aprepitant and/or dexamethasone. The proportions of patients with complete control (CC) during the overall (during the 6 days after the start of the chemotherapy), acute (up to 2 days), and delayed (3 to 6 days) phases were assessed. CC was defined as complete response with only grade 0–1 nausea, no vomiting, and no use of antiemetic rescue medication. Granisetron or palonosetron alone were administered to 9 and 19 patients, respectively. Aprepitant and/or dexamethasone were combined with granisetron and palonosetron in 28 and 5 patients, respectively. Acute CINV was completely controlled in all patients. Both granisetron monotherapy and palonosetron combination therapy could provide good control of delayed CINV, although the CC rates during the delayed and overall phases were not significantly different among mono- and combination therapy of the antiemetics. There was no significant difference in the frequencies of adverse drug events between the granisetron and palonosetron treatment groups. The present study showed that the antiemetic efficacy and safety of granisetron-based therapy were non-inferior to those of palonosetron-based therapy. Taken together with treatment costs, granisetron monotherapy would be adequate to prevent CINV in patients with non-Hodgkin lymphoma receiving bendamustine-based chemotherapy..

Here, we present three post-allogeneic SCT patients who developed pulmonary infection caused by M. abscessus complex including M. abscessus and M. massiliense. In all three cases, macrolide antibiotics had been administered for bronchiolitis obliterans syndrome (BOS) before the confirmation of their infection, and macrolide resistance was noted in the M. abscessus isolates, one of which resulted in an unfavorable treatment outcome. It is important to consider M. abscessus lung infection as well as other NTM in patients receiving allo-SCT, particularly those receiving macrolide therapy for BOS..

Final results of the phase II GATS study, Japanese journal of clinical oncology, 10.1093/jjco/hyy087, 48, 8, 736-742, 2018.01, Background: Shorter duration of infusion of monoclonal antibody treatments May reduce treatment burden and improve healthcare resource utilization. Methods: This phase II study recruited Japanese patients with previously untreated CD20+ B-cell non-Hodgkin lymphoma. Patients received intravenous obinutuzumab 1000 mg by regular infusion on Days 1, 8 and 15 of Cycle 1, followed by 90-min shorter duration of infusion in up to seven subsequent cycles, provided they received ≥3 regular infusions without any grade ≥3 infusion-related reactions and had a lymphocyte count <5.0 × 10
9
cells/l. Standard cyclophosphamide, doxorubicin, vincristine and prednisolone chemotherapy was given in Cycles 1–6. The primary endpoints were as follows: incidence of grade ≥3 infusion-related reactions in Cycle 2 in patients who started shorter duration of infusion in Cycle 2, serum obinutuzumab concentrations and phar-macokinetic parameters and the time course of cytokine release. Adverse events and serious adverse events were monitored. Results: Of 35 patients treated, 28 completed eight cycles; 31 started shorter duration of infusion in Cycle 2 and two patients in subsequent cycles. Two patients discontinued before starting shorter duration of infusion. No grade ≥3 infusion-related reactions occurred in Cycle 2. Twenty-one infusion-related reactions (all grades 1–2) were reported in 17/35 (49%) patients overall, mostly in Cycle 1 (18/21 infusion-related reactions [86%]). Grade ≥3 AEs occurring in ≥10% of patients included neutropenia/neutrophil count decreased (66%) and leukopenia/white blood cell count decreased (23%). Steady-state pharmacokinetics of obinutuzumab were attained in Cycle 2 and were not affected by shorter duration of infusion. No relevant cytokine elevations were reported with shorter duration of infusion. Conclusions: Regular infusion and shorter duration of infusion of obinutuzumab have comparable tolerability and pharmacokinetics in Japanese patients..

Using single-cell transcriptome analysis, we have identified a cluster of cells within immature hematopoietic stem- and progenitor-cell populations that specifically expresses genes related to the megakaryocyte lineage. We used CD41 as a positive marker to identify these cells within the CD34+CD38+IL-3RαdimCD45RA- common myeloid progenitor (CMP) population. These cells lacked erythroid and granulocyte-macrophage potential but exhibited robust differentiation into the megakaryocyte lineage at a high frequency, both in vivo and in vitro. The efficiency and expansion potential of these cells exceeded those of conventional bipotent megakaryocyte/erythrocyte progenitors. Accordingly, the CD41+ CMP was defined as a unipotent megakaryocyte progenitor (MegP) that is likely to represent the major pathway for human megakaryopoiesis, independent of canonical megakaryocyte-erythroid lineage bifurcation. In the bone marrow of patients with essential thrombocythemia, the MegP population was significantly expanded in the context of a high burden of Janus kinase 2 mutations. Thus, the prospectively isolatable and functionally homogeneous human MegP will be useful for the elucidation of the mechanisms underlying normal and malignant human hematopoiesis.

We used echocardiography to noninvasively assess the incidence of PH in 105 patients with chronic myeloid leukaemia (CML) treated with imatinib (n = 37), nilotinib (n = 30) or dasatinib (n = 38). The mean triscupid regurgitation peak gradient (TRPG), which reflects pulmonary arterial pressure, was 22·7 mmHg in the imatinib group, 23·1 mmHg in the nilotinib group and 23·4 mmHg for dasatinib group. These values were not significantly different, but higher than those (19·0 mmHg) in newly diagnosed CML patients. A TRPG > 31 mmHg, marking possible PH onset, was detected in 9 of 105 patients: one (2·7%) treated with imatinib, three (10·0%) with nilotinib and five (13·2%) with dasatinib. Only three patients complained of dyspnoea, whereas the other six were asymptomatic. In addition, there was a tendency toward correlation of TRPG value and age or TKI treatment duration. These results suggested that treatment with not only dasatinib, but also imatinib and nilotinib, can be associated with subclinical PH. Noninvasive echocardiography is useful for screening, especially in older patients with long-term TKI treatment..

Peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS) is also a highly aggressive lymphoma. These two diseases can often be confused with each other; therefore, we aimed to determine the clinical and pathological differences between T-PLL and PTCL-NOS. Methods: We analyzed 15 T-PLL and 91 PTCL-NOS patients and also compared clinical features between T-PLL and PTCL-NOS with leukemic presentation. Peripheral blood images and biopsy specimens were analyzed, and treatment responses were determined via imaging modalities. The clinicopathological characteristics were statistically compared. Results: T-PLL cells were smaller in size than those of PTCL-NOS with leukemic presentation (P=.0068); moreover, PTCL-NOS cells with leukemic presentation were smaller than those of PTCL-NOS without leukemic presentation (P=.0017). Immunophenotypic patterns in T-PLL and PTCL-NOS were similar. Five-year overall survival rates of T-PLL and all PTCL-NOS patients were 57.5% and 36.8%, respectively. No significant differences were found in clinical manifestations or prognoses; T-PLL and PTCL-NOS with leukemic presentation had essentially equivalent characteristics. Conclusion: T-PLL and PTCL-NOS may share common biological and clinical characteristics in Japanese patients..

Unexpectedly, we found a small but significant increase in the population of immature granulocytes and erythrocytes/megakaryocytes in peripheral blood in 16 of 22 patients (73%) treated with dexamethasone in combination with bortezomib and immunomodulatory drugs (triplet), but not in any of 25 patients treated with either bortezomib or immunomodulatory drugs with dexamethasone (doublet). These immature cells gradually increased to a peak level (mean 2.6% per white blood cells) with triplet therapy, and disappeared immediately after therapy cessation. The numbers of circulating CD34+ cells and colony-forming cells derived from peripheral blood mononuclear cells increased after triplet therapy compared with those in patients treated by either bortezomib or immunomodulatory drugs plus dexamethasone. Furthermore, triplet regimen downregulated the expression of CXCR4, a chemokine receptor essential for bone marrow retention, on CD34+ cells, suggesting an unexpected effect on normal hematopoietic stem/progenitor cells through the reduced interaction with the bone marrow microenvironment. Our observations suggest that combination use should be carefully evaluated to exert synergistic anti-myeloma effects while avoiding unexpected adverse events..

Although pretransplant conditioning regimen has been appreciated as a cause of ovarian failure, increased application of reduced-intensity conditioning allowed us to revisit other factors possibly affecting ovarian function after allogeneic SCT. We have addressed whether donor T-cell-mediated graft-versus-host disease (GVHD) could be causally related to female infertility in mice. Histological evaluation of the ovaries after SCT demonstrated donor T-cell infiltration in close proximity to apoptotic granulosa cells in the ovarian follicles, resulting in impaired follicular hormone production and maturation of ovarian follicles. Mating experiments showed that female recipients of allogeneic SCT deliver significantly fewer newborns than recipients of syngeneic SCT. GVHD-mediated ovary insufficiency and infertility were independent of conditioning. Pharmacologic GVHD prophylaxis protected the ovary from GVHD and preserved fertility. These results demonstrate for the first time that GVHD targets the ovary and impairs ovarian function and fertility and has important clinical implications in young female transplant recipients with nonmalignant diseases, in whom minimally toxic regimens are used..

A total of 74 patients with non-Hodgkin lymphoma were included in this study (April 2007 to December 2015). Palonosetron (0.75 mg) or granisetron (3 mg) was intravenously administered before R-CHOP therapy. The proportions of patients with complete response (CR) during the overall (0-120 h after the start of R-CHOP therapy), acute (0-24 h) and delayed (24-120 h) phases were evaluated. CR was defined as no vomiting and no use of antiemetic rescue medication. A total of 32 and 42 patients were treated with palonosetron and granisetron, respectively. The CR rate in the palonosetron group was significantly higher than that in the granisetron group during the delayed phase (90.6 and 61.9%, respectively; p=0.007). Logistic regression analysis showed that use of palonosetron improved the CR rate during the delayed phase, compared to use of granisetron. Female sex, age less than 60 years, no habitual alcohol intake, and Eastern Cooperative Oncology Group performance status (ECOG-PS) score of 1 were significant risk factors associated with non-CR. The findings of this study suggested the superiority of palonosetron to granisetron, without accompanying dexamethasone and aprepitant, for chemotherapy-induced nausea and vomiting in patients with malignant lymphoma..

Ruxolitinib (RUXO), a novel JAK1/2 inhibitor, can be used as a bridging therapy until allo-SCT can be performed to reduce TRM. We herein report a RUXO-treated MF patient who developed recurrent subcutaneous Sweet’s disease (SSD) that was successfully treated by the administration of systemic glucocorticoids. We performed allo-SCT as previously scheduled, resulting in a good clinical course without deterioration of SSD. RUXO administration, as well as MF itself, might therefore sometimes cause this rare non-infectious event..

Graft-versus-host disease (GVHD) and infections are the major obstacles of HSCT, and their close relationship has been suggested. Although roles of bacterial and viral infections in the pathophysiology of GVHD are well described, impacts of fungal infection on GVHD remain to be elucidated. In mouse models of GVHD, injection of α-mannan (Mn), a major component of fungal cell wall, or heat-killed Candida albicans exacerbated GVHD, particularly in the lung. Mn-induced donor T-cell polarization toward Th17 and lung-specific chemokine environment in GVHD led to accumulation of Th17 cells in the lung. The detrimental effects of Mn on GVHD depended on donor IL-17A production and host C-type lectin receptor Dectin-2. These results suggest a previously unrecognized link between pulmonary GVHD and fungal infection after allogeneic HSCT..

a single-center experience., Gan to kagaku ryoho. Cancer & chemotherapy, 35, 1, 99-104, 2008.01, In our institute, tacrolimus was started at a dose of 0.03 mg/kg/day and adjusted to maintain a blood concentration between 10 and 20 ng/mL combined with short term methotrexate after bone marrow transplantation from an unrelated donor. Dose adjustment was performed strictly, in order to prevent grade II-IV acute graft-versus-host disease (GVHD)while avoiding renal toxicity of tacrolimus. Then, in this study, we retrospectively evaluated the tacrolimus blood concentration during the first 4 weeks after transplantation. The mean tacrolimus concentration of the eligible 52 patients was 17.41+/-4.84(range, 9.5-33.4)ng/mL in the 1st week after transplantation, but declined to 13.7+/- 4.0(range, 8.1-25.6)ng/mL in the 2nd week. The dose of tacrolimus was decreased as follows: 0.022+/-0.005 mg/ kg/day(range 0.011-0.039)in the 1st week, and 0.018+/-0.007 mg/kg/day(range 0.004-0.040)in the 2nd week. The incidence of grade II-IV GVHD was 63.0% and grade III-IV was 13.9%. The individual variations of tacrolimus blood concentration did not affect the incidence of grade II-IV acute GVHD, as far as the concentration being maintained in the range of 14.82+/-4.22 ng/mL during the first 4 weeks after transplantation. In addition, the variations of tacrolimus concentration didn?t associate statistically with renal toxicity..

It was developed based on the knowledge that graft-versus-tumor (GVT) effect is the main anti-tumor effect in allogeneic HSCT. Because RIST is associated with less morbidity and mortality, it can be applied to many patients who could not undergo conventional HSCT. Experiences in the last decade clarified many issues related to RIST. For example, graft-versus-host disease (GVHD) in RIST may differ in character compared to conventional HSCT. Also, it is now known that intensity of conditioning is important in disease control, and the optimal regimens may be different for each disease or for each disease status. There are still many unsolved questions, and large prospective randomized trials are necessary to resolve these..

There was no difference in the number of CD34+ cells among PBSC between the non-rituximab and the rituximab groups. Although B-cells were completely depleted from PBSC in the rituximab group, we found no difference in the expression of CXCR-4, VLA-4 and c-Kit on PBSC, indicating that rituximab did not affect the expression of these adhesion molecules, which might be involved in the mechanism of mobilization. There was no significant difference in the recovery of neutrophils and platelets, transplant-related toxicity and post-transplant complications between the two groups. Despite the short follow-up, there was no significant difference in progression-free survival between the two groups. These results indicated no adverse effect of rituximab on the mobilization and engraftment of PBSC. Larger studies are required to determine the impact of rituximab on the mobilization and function of PBSC as well as whether a survival advantage exists in patients who undergo auto-PBSCT with rituximab..

Retrospective Analysis of Data from the Japan Marrow Donor Program, Biology of Blood and Marrow Transplantation, 10.1016/j.bbmt.2006.09.002, 13, 1, 90-99, 2007.01, Allogeneic hematopoietic stem cell transplantation (allo-HSCT) from an HLA-matched related donor has been suggested to improve the poor prognosis of adult T-cell leukemia/lymphoma (ATLL). However, the infusion of HTLV-I-infected cells from HTLV-I-positive related donors could lead to the development of donor-derived ATLL under immunosuppressive conditions. Although most ATLL patients lack a suitable HLA-matched related donor and require an HTLV-I-negative unrelated donor, little information is currently available regarding the outcome of unrelated bone marrow transplantation (UBMT) for ATLL. To evaluate the role of UBMT in treating ATLL, we retrospectively analyzed data from 33 patients with ATLL treated by UBMT through the Japan Marrow Donor Program (JMDP). Overall survival (OS), progression-free survival, and cumulative incidence of disease progression and progression-free mortality at 1 year after UBMT were 49.5%, 49.2%, 18.6%, and 32.3%, respectively. Multivariate analysis identified recipient age as an independent prognostic factor for OS (P = .044). Patients age ≥50 years who showed nonremission at transplantation tended to have higher rates of treatment-related mortality. Our observations suggest that UBMT could represent a feasible treatment option for ATLL patients and warrant further investigation based on these risk factors..

He developed thrombotic complications at multiple sites. Thrombophlebitis of the hemorrhoidal plexus became exacerbated and developed into critical cellulitis. Because the patient had no human leukocyte antigen-identical sibling, we considered an alternative donor. Because of the necessity for early neutrophil recovery to resolve the critical infection, we proceeded with allogeneic peripheral blood stem cell transplantation (PBSCT) from a microchimeric haploidentical sibling donor. We infused peripheral blood mononuclear cells directly into the patient without cryopreservation and thawing procedures. We aimed for the contaminating granulocytes to act as a granulocyte transfusion. Actually, the neutrophils increased to 1.6 × 109/L on day 1, when the patient showed a temporary resolution of infection. Engraftment was achieved shortly after neutropenic nadir, and acute graft-versus-host disease (GVHD) has been well controlled. Although the patient experiences extensive chronic GVHD, he has been well as an outpatient with a 90% Karnofsky performance status score. The leukemia has been in complete remission for more than 1 year. These findings suggest the clinical utility of a salvage therapy with allogeneic PBSCT from a microchimeric haploidentical donor to treat refractory leukemia concurrent with life-threatening infection..

She received remission-reinduction chemotherapy combined with imatinib mesylate. After the documentation of the molecular remission of Ph+ALL, she underwent the second allo-BMT from another unrelated donor. GVHD prophylaxis consisted of tacrolimus (TAC) and short-term methotrexate. On day 21, she suddenly suffered from an intermittent severe, cramp-like pain in the right lower limb. The typical pain profile and exclusion of other causative diseases suggested calcineurin-inhibitor induced pain syndrome (CIPS) as a possible cause of pain. The pain was gradually relieved after discontinuation of TAC and administration of several analgesic drugs. CIPS is rarely seen following allogeneic stem cell transplantation (allo-SCT); only three cases have been so far reported to our knowledge. Thus, physicians should be alert to this complication in patients receiving allo-SCT..

Such mobilization has a great clinical impact on hemopoietic stem cell transplantation. Underlying mechanisms are incompletely understood, but may involve G-CSF-induced modulation of chemokines, adhesion molecules, and proteolytic enzymes. We studied G-CSF-induced mobilization of CD34 +CD10+CD19-Lin- and CD34 +CD10+CD19+Lin- cells (early B and pro-B cells, respectively). These mobilized lymphoid populations could differentiate only into B/NK cells or B cells equivalent to their marrow counterparts. Mobilized lymphoid progenitors expressed lymphoid- but not myeloid-related genes including the G-CSF receptor gene, and displayed the same pattern of Ig rearrangement status as their bone marrow counterparts. Decreased expression of VLA-4 and CXCR-4 on mobilized lymphoid progenitors as well as multipotent and myeloid progenitors indicated lineage-independent involvement of these molecules in G-CSF-induced mobilization. The results suggest that by acting through multiple trans-acting signals, G-CSF can mobilize not only myeloid-committed populations but a variety of resident marrow cell populations including lymphoid progenitors..

The plasma antithrombin activity was decreased and hardly compensated by concentrated antithrombin preparation due to high consumption rate. However, successful anticoagulation was achieved by administration of direct thrombin inhibitor, argatroban. Family studies of antithrombin activity revealed that she had type I congenital antithrombin deficiency. A novel heterozygous mutation in the gene for antithrombin (single nucleotide T insertion at 7916 and 7917, Glu 272 to stop in exon 4) was identified. Argatroban administration would be effective in the treatment of congenital antithrombin deficiency with SMV thrombosis..

Tyk2 is required for the induction and nuclear translocation of Daxx which regulates IFN-α-induced suppression of B lymphocyte formation, Journal of Immunology, 169, 9, 4707-4711, 2002.11, IFN-α inhibits B lymphocyte development, and the nuclear protein Daxx has been reported to be essential for this biological activity. We show in this study that IFN-α inhibits the clonal proliferation of B lymphocyte progenitors in response to IL-7 in wild-type, but not in tyk2-deficient, mice. In addition, the IFN-α-induced up-regulation and nuclear translocation of Daxx are completely abrogated in the absence of tyk2. Therefore, tyk2 is directly involved in IFN-α signaling for the induction and translocation of Daxx, which may result in B lymphocyte growth arrest and/or apoptosis..

Although he had HLA-DRB1 0405 and a positive rheumatoid factor, he was unlikely to develop rheumatoid arthritis (RA) according to diagnostic criteria. However, the patient developed RA 40 days after transplantation. Our experience suggests that the systemic autoimmune disease, RA, may occur in patients with predisposing factors after autologous PBSCT..

Comparison of an antigenemia assay and quantitative real-time polymerase chain reaction, Bone Marrow Transplantation, 10.1038/sj/bmt/1703513, 29, 7, 599-606, 2002.06, Cytomegalovirus (CMV) antigenemia and quantitative real-time polymerase chain reaction (PCR) were compared for monitoring of CMV reactivation after allogeneic stem cell transplantation. The number of CMV antigen-positive cells by the antigenemia assay and the level of CMV DNA by real-time PCR correlated well. The sensitivity and specificity of the antigenemia assay was 55.4% and 95.5%, respectively, using real-time PCR as the reference standard. The probability of positive antigenemia at day 100 was 76.5%, with a median of first detection at day 37 in 51 patients, compared with a positive PCR of 84.3% and day 33, respectively. When HLA-identical sibling donor transplant recipients and other donor transplant recipients were analyzed separately, there was no difference between the two tests. However, temporal patterns of first detection of CMV antigen-positive cells and CMV DNA differed between HLA-identical and alternative recipients; patients without CMV (29%) or with sporadic positive PCR results (14%) were more common in HLA-identical sibling transplants, wereeas patients with simultaneous antigenemia and positive PCR occurred more in alternative transplants (48%). Two of 51 patients (4%) developed CMV colitis despite antigenemia-guided prophylaxis, but both were successfully treated with ganciclovir. Although PCR is more sensitive than antigenemia, both tests are useful in the early detection of CMV after allogeneic stem cell transplantation..

Four years later she was diagnosed with chronic myelogenous leukaemia (CML). The BCR/ABL fusion gene was detected in both peripheral blood and bone marrow cells by reverse transcription-polymerase chain reaction, but not in the harvest product of peripheral blood stem cells which were infused at the time of transplantation. This case adds to the accumulating evidence of therapy-related CML developing after high-dose chemotherapy and autologous stem cell transplantation..
