OBJECTIVES: The Innovative Medicines Initiative-funded, multistakeholders project Healthcare Alliance for Resourceful Medicine Offensive Against Neoplasms in hematologY (HARMONY) created a task force involving patient organizations, medical associations, pharmaceutical companies, and health technology assessment/regulator agencies' representatives to evaluate the suitability of previously established value frameworks (VFs) for assessing the clinical and societal impact of new interventions for hematologic malignancies (HMs). METHODS: Since the HARMONY stakeholders identified the inclusion of patients' points of view on evaluating VFs as a priority, surveys were conducted with the patient organizations active in HMs and part of the HARMONY network, together with key opinion leaders, pharmaceutical companies, and regulators, to establish which outcomes were important for each HM. Next, to evaluate VFs against the sources of information taken into account (randomized clinical trials, registries, real-world data), structured questionnaires were created and filled by HARMONY health professionals to specify preferred data sources per malignancy. Finally, a framework evaluation module was built to analyze existing clinical VFs (American Society of Clinical Oncology, European Society of Medical Oncology, Magnitude of Clinical Benefit Scale, Institut für Qualität und Wirtschaftlichkeit im Gesundheitswesen, Institute for Clinical and Economic Review, National Comprehensive Cancer Network Evidence Blocks, and patient-perspective VF). RESULTS: The comparative analysis describes challenges and opportunities for the use of each framework in the context of HMs and drafts possible lines of action for creating or integrating a more specific, patient-focused clinical VF for HMs. CONCLUSIONS: None of the frameworks meets the HARMONY goals for a tool that applies to HMs and assesses in a transparent, reproducible, and systematic way the therapeutic value of innovative health technologies versus available alternatives, taking a patient-centered approach and using real-world evidence.

Purpose: Survival of acute leukemia (AL) patients following umbilical cord blood transplantation (UCBT) is dependent on an array of individual features. Integrative models for risk assessment are lacking. We sought to develop a scoring system for prediction of overall survival (OS) and leukemia-free survival (LFS) at 2 years following UCBT in AL patients.Experimental Design: The study cohort included 3,140 pediatric and adult AL UCBT patients from the European Society of Blood and Marrow Transplantation and Eurocord registries. Patients received single or double cord blood units. The dataset was geographically split into a derivation (n = 2,362, 65%) and validation set (n = 778, 35%). Top predictors of OS were identified using the Random Survival Forest algorithm and introduced into a Cox regression model, which served for the construction of the UCBT risk score.Results: The score includes nine variables: disease status, diagnosis, cell dose, age, center experience, cytomegalovirus serostatus, degree of HLA mismatch, previous autograft, and anti-thymocyte globulin administration. Over the validation set an increasing score was associated with decreasing probabilities for 2 years OS and LFS, ranging from 70.21% [68.89–70.71, 95% confidence interval (CI)] and 64.76% (64.33–65.86, 95% CI) to 14.78% (10.91–17.41) and 18.11% (14.40–22.30), respectively. It stratified patients into six distinct risk groups. The score's discrimination (AUC) over multiple imputations of the validation set was 68.76 (68.19–69.04, range) and 65.78 (65.20–66.28) for 2 years OS and LFS, respectively.Conclusions: The UCBT score is a simple tool for risk stratification of AL patients undergoing UCBT. Widespread application of the score will require further independent validation. Clin Cancer Res; 23(21); 6478–86. ©2017 AACR.

High-level performance in mountain sports would be unlikely unless different emotional factors are taken into account through the analysis of psychological characteristics, such as mood, resilience, or motivation, among many other variables. In this study, 788 people with a sports degree from the Spanish Federation of Mountain Sports and Climbing (FEDME) participated, 75.3% of whom were men and 24.5% of whom were women. The mean age of the participants was 49.8 years (±12.8), ranging from 18 to 76 years. The Wong Law Emotional Intelligence Scale (WLEIS-S), the RS-14 Resilience Scale, and the Satisfaction with Life Scale (SWLS) instruments were used. The aim of this research was to determine the relationship between the dimensions of emotional intelligence, resilience, and life satisfaction. The results showed a relationship between several of the dimensions from the instruments used (p < 0.01). In terms of gender, higher scores were found for women than for men. The regression model shows that both the dimensions of emotional intelligence [appraisal of own emotions (β = 0.104; p < 0.001); use of emotions (β = 0.30; p < 0.001); emotional regulation (β = 0.103; p < 0.001)] and resilience [personal competence (β = 0.402; p < 0.001)] are predictors of greater life satisfaction, positively explained by the regression model with 44.1% accuracy. Further proposals should extend the results obtained to the analysis of more sports modalities to provide evidence that would complement those extracted in this research.

Contains fulltext : 290857.pdf (Publisher’s version ) (Closed access) Information on causes of death (CoDs) and the impact of myelodysplastic syndromes (MDS) on survival in patients with lower-risk MDS (LR-MDS) is limited. A better understanding of the relationship between disease characteristics, clinical interventions and CoDs may improve outcomes of patients with LR-MDS. We prospectively collected data on patients with LR-MDS in the European MDS registry from 2008 to 2019. Clinical, laboratory and CoDs data were obtained. To examine MDS-specific survival, relative survival (RS) was estimated using national life tables. Of 2396 evaluated subjects, 900 died (median overall survival [OS]: 4.7 years; median follow-up: 3.5 years). The most common CoDs were acute myeloid leukaemia/MDS (20.1%), infection (17.8%) and cardiovascular disease (CVD; 9.8%). Patients with isolated del(5q) and with red cell transfusion needed during the disease course, had a higher risk of fatal CVD. The 5-year OS was 47.3% and the 5-year RS was 59.6%, indicating that most patients died due to their underlying MDS. Older patients (aged >80 years) and the lowest-risk patients were more likely to die from competing causes. This study shows that MDS and its related complications play crucial role in the outcome of patients with LR-MDS. 01 februari 2023

The impact of GVHD and graft-versus-leukemia effect in unrelated cord blood transplantation (UCBT) is controversial. In the Eurocord/ALWP EBMT and JSTCT/JDCHCT collaborative study, we evaluated the impact of GVHD on UCBT outcomes in Japanese and European registries. A total of 3, 690 adult patients with acute leukemia who received their first single UCBT were included. A multivariate analysis of overall survival (OS) revealed a positive impact of grade II acute GVHD compared with grade 0-I GVHD, in the Japanese cohort (hazard ratio (HR), 0.81; P = 0.001), and an adverse impact in the European cohort (HR, 1.37; P = 0.007). A negative impact of grade III-IV acute GVHD on OS was observed regardless of registries. In the analysis of relapse, a positive impact of grade II acutes GVHD compared with grade 0–I GVHD was observed only in the Japanese cohort, regardless of disease risk. The positive impact of limited chronic GVHD on OS was observed only in the Japanese cohort. In conclusion, a positive impact of mild GVHD after a single UCBT was observed only in the Japanese cohort. This could explain the ethnic difference in UCBT outcomes and might contribute to the preference usage of UCBT in Japan., 急性白血病治療における臍帯血移植後の合併症が及ぼす予後への影響 --国際共同研究から明らかになった日欧での違い--. 京都大学プレスリリース. 2021-10-19.

In myelodysplastic syndromes (MDS), the 20q deletion [del(20q)] may cause deletion of the ASXL1 gene. We studied 153 patients with MDS and del(20q) to assess the incidence, prognostic value and impact on response to azacitidine (AZA) of ASXL1 chromosomal alterations and genetic mutations. Additionally, in vitro assay of the response to AZA in HAP1 (HAP1(WT)) and HAP1 ASXL1 knockout (HAP1(KN)) cells was performed. ASXL1 chromosomal alterations were detected in 44 patients (28 center dot 5%): 34 patients (22%) with a gene deletion (ASXL1(DEL)) and 10 patients (6 center dot 5%) with additional gene copies. ASXL1(DEL) was associated with a lower platelet count. The most frequently mutated genes were U2AF1 (16%), ASXL1 (14%), SF3B1 (11%), TP53 (7%) and SRSF2 (6%). ASXL1 alteration due to chromosomal deletion or genetic mutation (ASXL1(DEL)/ASXL1(MUT)) was linked by multivariable analysis with shorter overall survival [hazard ratio, (HR) 1 center dot 84; 95% confidence interval, (CI): 1 center dot 11-3 center dot 04; P = 0 center dot 018] and a higher rate for acute myeloid leukaemia progression (HR 2 center dot 47; 95% CI: 1 center dot 07-5 center dot 70, P = 0 center dot 034). ASXL1(DEL)/ASXL1(MUT) patients were correlated by univariable analysis with a worse response to AZA. HAP1(KN) cells showed more resistance to AZA compared to HAP1(WT) cells. In conclusion, ASXL1 alteration exerts a negative impact on MDS with del(20q) and could become useful for prognostic risk stratification and treatment decisions.

Introduction: Hundreds of millions of people practice winter sports worldwide. Alpine skiing and snowboarding are associated with a possible risk of injury. There are at least three important factors that can affect safety in wilderness activities (environmental factors, technical factors and human factors). Awareness of human factors would allow us to reduce the risk in winter sports. Material and method: The objective of this study is to find out, through a self-explanatory cross-sectional personal survey, what and how human factors are involved in alpine skiing and snowboarding accidents. Results: 219 surveys were carried out of a total of 3,911 patients attended at the different health care points. The highest percentage of respondents related their accident to distraction or complacency, both in 72.2% of the respondents. Other factors that were pointed out by more than 50% were; lack of knowledge (60.4%), lack of following the norms (58.5%), fatigue (57.5%), lack of situational awareness (57%) and stress with (53.8% of the respondents). Conclusions: By identifying these most frequent human factors during downhill skiing and snowboarding, actions can be taken to prevent or contain human error.

Despite a detailed understanding of the genes mutated in myelodysplastic syndromes (MDS), diagnostic and treatment decisions for patients with MDS rely primarily on clinical and cytogenetic variables as considered by the Revised International Prognostic Scoring System (IPSS-R). Here we describe the recently developed Molecular IPSS (IPSS-M), a clinico-genomic risk stratification system that considers clinical, cytogenetic and genetic parameters; the implementation of a web portal to facilitate its adoption, a strategy to handle missing variables, and the worldwide utilization of the web calculator as a clinical support tool. The IPSS-M was trained on 2,957 clinically annotated diagnostic MDS samples profiled for mutations in 156 driver genes. To maximize the clinical applicability of the IPSS-M and account for missing genetic data (i.e genes missing from a sequencing panel), we implemented a strategy to calculate a risk score under three scenarios: best, worst and average. Last, we developed an online calculator as a standalone single-page web application using VueJs, and D3Js for the interactive visualizations, deployed through a CI/CD pipeline on AWS, where collection of anonymous usage analytics allows to track adoption and usability of the new proposed model. The model incorporates clinical, morphological, genetic variables informed by cytogenetics and constructed from the presence of oncogenic mutations in 31 genes. It delivers a unique risk score for each individual patient, as well as an assignment to one of six IPSS-M risk strata. Compared to the IPSS-R the IPSS-M re-stratified 46% of MDS patients. The model was validated in an external dataset of 754 MDS patients. We released an open-access IPSS-M web calculator available at https://mds-risk-model.com. By specifying the patient clinical and molecular profiles, the tool returns the patient-specific IPSS-M risk score and category, and the probability estimates over time for three clinical endpoints, i.e. leukemia free survival (LFS), overall survival, and incidence of leukemic transformation. Since its launch in June 2022, the calculator has been used by >6000 users in >75 countries, reaching a daily average of 100 users per day. Risks have been calculated for >45,000 patient profiles. 99.28% of the sessions initiated reach an IPSS-M score, suggesting that the calculator is intuitive and easy to use. We trained and validated the IPSS-M on 3,711 patients, a patient tailored risk stratification tool for patients with MDS that considers clinical, morphological and genetic variables inclusive of cytogenetics and mutations in one of 31 genes. The development of a web based tool was instrumental to the global dissemination of the model, enabling non-expert users to leverage the power of molecular biomarkers in risk stratification for patients with MDS.

Characteristics and risk factors (RFs) of community-acquired respiratory virus (CARV) infections after umbilical cord blood transplantation (UCBT) are lacking. We retrospectively analyzed CARV infections in 216 single-unit myeloablative UCBT recipients. One-hundred and fourteen episodes of CARV infections were diagnosed in 62 (29%) patients. Upper respiratory tract disease (URTD) occurred in 61 (54%) whereas lower respiratory tract disease (LRTD) in 53 (46%). The 5-year cumulative incidence of CARV infection was 29%. RFs for developing CARV infections were: prednisone-based graft-versus-host disease (GVHD) prophylaxis and grade II–IV acute GVHD. RFs analysis of CARV progression to LRTD identified 2007–2009 period and absolute lymphocyte count (ALC)

Highlights • Rapid detection methods used as first diagnostic test for CARVs may delayed the start of antiviral therapy in a significant number of influenza and RSV cases. • Syndromic multiplex RT-PCR-based prospective clinical CARV survey in allo-HCT recipients translates into a lower mortality rate as compared to standard clinical practice based on RSV and influenza virus rapid detection test. • We found that donor/recipient HLA mismatch, CARV LRTD and high-risk ISI were also associated with higher mortality., Background There is a lack of studies comparing clinical outcomes among retrospective versus prospective cohorts of allogeneic stem cell transplant (allo-HCT) recipients with community acquired respiratory virus (CARV) infections. Methods We compare outcomes in two consecutive cohorts of allo-HCT recipients with CARV infections. The retrospective cohort included 63 allo-HCT recipients with 108 CARV infections from January 2013 to April 2016 who were screened and managed following standard clinical practice based on influenza and respiratory syncytial virus rapid antigen detection methods. The prospective cohort was comprised of 144 consecutive recipients with 297 CARV episodes included in a prospective interventional clinical surveillance program (ProClinCarvSur-P) based on syndromic multiplex PCR as first-line test from May 2016 to December 2018 at a single transplant center. Results CARV infections in the retrospective cohort showed more severe clinical features at the time of diagnosis compared to the prospective cohort (fever 83% vs. 57%, hospital admission 69% vs. 28% and lower respiratory tract 58% vs. 31%, respectively, p ≤ 0.002 for all comparisons). Antiviral therapy was more commonly prescribed in the prospective cohort (69 vs. 43 treated CARV episodes), particularly at the upper respiratory tract disease stage (34 vs. 12 treated CARV episodes). Three-month all-cause mortality was significantly higher in the retrospective cohort (n = 23, 37% vs. n = 10, 7%, p

We analyzed the outcomes of 26 consecutive patients with acquired severe aplastic anemia (SAA) undergoing peripheral blood stem cell transplantation (PBSCT) with partial ex vivo T cell depletion with a targeted T cell dose from HLA-identical sibling donors. The median patient age was 37 years (range, 3 to 63 years). Four patients with uncontrolled pneumonia at the time of transplantation died, on days +1, +2, +21, and +26. All evaluable patients engrafted, with a median time to neutrophil recovery of 11 days (range, 10 to 14 days) and a median time to platelet recovery of 19 days (range, 8 to 53 days). Two patients had transient grade I acute graft-versus-host disease (GVHD) with skin involvement, but no patients developed grade II-IV acute GVHD. Two patients had mild skin chronic GVHD, and 1 patient had moderate chronic GVHD with ocular involvement. No relapse was observed after a median follow-up of 114 months (range, 4 to 233 months). The overall cumulative incidence of TRM at 10 years was 19%, whereas it was 5% for those with a Karnofsky Performance Status (MPS) score >60 at the time of transplantation. Disease-free survival, overall survival, and GVHD and relapse-free survival at 10 years were 81%, 81%, and 80%, respectively, for all patients and 95%, 95%, and 90%, respectively, for patients with a MPS score >60 at transplantation. Our data indicate that PBSCT with partial ex vivo T cell-depleted targeted cell dose grafts from an HLA-identical sibling donor is a feasible, safe, and effective approach to reduce GVHD and cure patients with SAA.

We report a case of pernicious anemia in which the first diagnosis suspicion was cold autoimmune hemolytic anemia (cAIHA) due to the presence of cold autoantibodies. A 47-year-old woman with a medical history of autoimmune thyroid disease came to the hospital with a clinical and serologic presentation of AIHA. However, because of determination of vitamin B12 (VB12) deficiency, she was finally diagnosed with megaloblastic anemia. In the acute period, the patient received short-term corticosteroid therapy and later VB12. The patient’s hemoglobin level and general condition showed improvement.

Percutaneous surgery is the treatment of choice of isolated aortic coarctation in adults However, when there are other heart problems related to aortic coarctation, its surgical management may vary. We report a 41-year-old male presenting with aortic coarctation associated with severe, symptomatic, bicuspid aortic valve lesions and significant left ventricular dysfunction. He underwent open heart surgery for the surgical resolution of these problems. One year after surgery the results are satisfactory with no evidence of postoperative complications and a significant improvement of patient symptoms and left ventricular function.

Omidubicel is an advanced cell therapy derived from umbilical cord blood (UCB) for use in allogeneic hematopoietic cell transplantation (HCT). A recent randomized phase 3 clinical trial demonstrated faster engraftment, shorter length of hospital stays, and lower rates of infection with omidubicel compared with standard UCB transplantation in patients with high-risk hematologic malignancies. Despite the proven clinical benefits of omidubicel, its impact on health-related quality of life (HRQL) from the patient's perspective has not been described. This study analyzed patient-reported HRQL measures collected prospectively in the randomized phase 3 trial comparing omidubicel to standard UCB transplantation. A total of 108 patients at 33 international stem cell transplantation centers underwent myeloablative allogeneic HCT with either omidubicel or standard UCB. Patients completed serial HRQL questionnaires at screening and on days 42, 100, 180, and 365 post-transplantation. The HRQL surveys included the Functional Assessment of Cancer Therapy-Bone Marrow Transplant (FACT-BMT), a 50-item cancer-specific questionnaire assessing physical, functional, emotional, social/family, and HCT-specific well-being, and the EuroQol 5-Dimension 3-Level, a 5-item generic HRQL survey. A mixed model with repeated measures was used to compare changes in HRQL from baseline in the 2 treatment arms. The average change in HRQL scores over time was compared by estimating the difference in the area under the curve (AUC) in each treatment group. Seventy-five patients (omidubicel arm, n = 37; standard UCB arm, n = 38) who completed the FACT-BMT at baseline and on 1 or more follow-up visits were included in this study. Baseline characteristics were similar in the 2 treatment arms. Over the first year post-transplantation, the AUCs of mean changes in physical, functional, and total FACT-BMT scores indicated significantly better HRQL with omidubicel (P.05), with mean differences across time points ranging from 1.4 to 3.1 points, 1.6 to 3.2 points, and 7.2 to 11.0 points, respectively. The minimal clinically important difference was exceeded at 1 or more time points for each of these measures. The HRQL improvements with omidubicel were observed as early as 42 days post-transplantation and persisted at 1 year, indicating the potential long-term benefits of omidubicel on HRQL. Across all patients, adverse clinical outcomes, such as grade 3 viral infections and lower rates of neutrophil engraftment, were associated with worse HRQL scores. The observed improvements in HRQL measures may reflect the known clinical benefits of omidubicel. Compared with standard UCB, allogeneic HCT with omidubicel resulted in significant and clinically meaningful improvements in patient-reported HRQL measures.

Patients with higher-risk myelodysplastic syndrome (HR-MDS) are defined by the original or revised International Prognostic Scoring System and specific genetic features. Treatment of HR-MDS is challenging. Allogeneic hematopoietic stem cell transplantation, the only curative approach, is feasible in a minority of fit or intermediate fitness patients aged

Although allogeneic hematopoietic stem cell transplantation (allo-HSCT) can be associated with neurologic complications, data on noninfectious etiologies are scanty. Therefore, we analyzed the incidence, clinical characteristics, risk factors, and influence on outcomes of noninfectious neurologic complications (NCs) in 971 consecutive patients with hematologic malignancies undergoing allo-HSCT at our center between January 2000 and December 2016. We evaluated NCs affecting the central nervous system (CNS) and peripheral nervous system (PNS). The median duration of follow-up of survivors was 71 months (range, 11 to 213 months). A total of 467 patients received a matched sibling donor (MSD) transplant, 381 received umbilical cord blood (UCB), 74 received a haploidentical transplant, and 49 received a matched unrelated donor (MUD) transplant. One hundred forty-nine (15.3%) NCs were documented at a median of 78 days after transplantation (range, 5 days before to 3722 days after). The cumulative incidence risk of developing NC was 7.5% (95% confidence interval, 6% to 8.2%) at day +90 and 13% at 5 years. The 5 -year cumulative incidence of NCs was 10.8% after MSD alto-HSCT and 15.3% after alternative donor (UCB, MUD, haploidentical) allo-HSCT (P=.004). There were 101 (68%) CNS complications, including encephalopathy, n = 46 (31%); headache, n = 20 (13%); stroke, n = 15 (10%); seizures, n = 9 (6%), posterior reversible encephalopathy syndrome, n = 6 (4%), and myelopathy, n = 5 (3%). PNS complications (32%) included neuropathies, n = 25 (17%), and myopathies and neuromuscular junction disorders, n = 23 (17%), with 17% of the total PNS complications being immune-related. In multivariable analysis, donor type other than MSD, age >= 40 years, development of acute graft-versus-host disease (GVHD) grade II-IV (hazard ratio [HR], 3.3; P < .00001), and extensive chronic GVHD (HR, 3.2; P=.0002) were independently associated with increased risk of NCs. The 5 -year overall survival (OS) was 21% in patients who developed NCs and 41% for those who did not (P < .0001). This difference in OS was observed in patients developing CNS NCs, but not in those developing PNS complications. In conclusion, our study reveals NCs as a frequent and heterogeneous complication that, when affecting CNS, is associated with poor prognosis following allo-HSCT.

Objectives Umbilical cord blood transplantation (UCBT) and haploidentical hematopoietic stem cell transplantation (haplo-HSCT) modalities have been developed to offset the lack of matched donors. In this study, we compare the transfusion requirements of patients undergoing UCBT and haplo-HSCT in a single institution with the aim of providing additional information for clinicians to choose the most adequate alternative graft for HSCT. Methods The study reviewed 67 and 46 patients undergoing UCBT and haplo-HSCT, respectively. Results There were no significant differences for RBC and PLT requirements according to the transplantation modality. Median time to RBC transfusion independence was 35 and 25.5 days in patients who received an UCBT and haplo-HSCT, respectively (P = 0.38), while median time to platelet transfusion independence was 31 days for UCBT patients and 23 for haplo-HSCT patients (P < 0.001). Days until neutrophils > 0.5 x 10(9)/L were the only variable that significantly influenced RBC and PLT requirements for both transplantation modalities. Cumulative incidence of RBC and PLT transfusion independence at 90 days after transplantation was similar for both UCBT and haplo-HSCT. Conclusions Both transplantation platforms require prolonged and intensive supportive RBC and PLT transfusion therapy. Both transplantation platforms require prolonged and intensive supportive RBC and PLT transfusion therapy.

Highlights • CMV DNA is frequently detected in BAL fluid specimens from allo-HSCT. • CMV DNA detection in BAL fluids is comparable across pneumonia etiologies. • CMV DNA loads in BAL fluids are comparable across pneumonia etiologies. • CMV DNA load in BAL may predict attributable-pneumonia mortality., Summary Objectives To date no definitive cut-off value for cytomegalovirus (CMV) DNA load in bronchoalveolar lavage (BAL) fluid specimens has been established to discriminate between CMV pneumonia and pulmonary CMV DNA shedding in allogeneic hematopoietic stem cell transplant (allo-HSCT) recipients. Methods The current retrospective study is aimed at assessing the range of CMV DNA loads quantified in BAL fluid specimens from allo-HSCT patients with pneumonia in which different microorganisms were causally involved. Results A total of 144 BAL specimens from 123 patients were included. CMV DNA was detected in 56 out of 144 BAL fluid specimens and the median CMV DNA load from patients in whom CMV pneumonia was unlikely or could be tentatively ruled out was 1210 (31–68, 920) IU/ml. The frequency of CMV DNA detection and median CMV DNA loads were comparable, irrespective of the attributable cause of pneumonia. Detection of CMV DNA loads in BAL fluid specimens >500 IU/ml was independently associated with pneumonia-attributable mortality. Conclusions The current study highlights the difficulty in establishing universal CMV DNA load thresholds in BAL fluid specimens for distinguishing between CMV pneumonia and pulmonary CMV DNA shedding, and suggests that the presence of CMV DNA in BAL fluid specimens beyond a certain level may have a deleterious impact on patient outcome.

OBJECTIVE Characteristics and risk factors (RFs) of invasive fungal disease (IFD) have been little studied in the setting of umbilical cord blood transplantation (UCBT). METHOD We retrospectively included 205 single-unit myeloablative UCBT recipients with a median follow-up of 64 months. RESULTS Fifty-six episodes of IFD were observed in 48 patients (23%) at a median time of 123 days after stem cell infusion. Invasive mold disease (IMD) occurred in 42 cases, 38 of them (90%) caused by invasive aspergillosis whereas invasive yeast disease (IYD) occurred in 14 cases, most of them due to candidemia (n = 12, 86%). The 5-year cumulative incidence of IFD, IMDs, and IYDs was 24% 19%, and 7%, respectively. In multivariate analysis, three RFs for IMDs were identified: age >30 years (HR 3.5, P = 0.017), acute grade II-IV graft-versus-host disease (HR 2.3, P = 0.011), and ≥1 previous transplant (HR 3.1, P = 0.012). The probability of IMDs was 2.5%, 14%, and 33% for recipients with none, 1, or 2-3 RFs, respectively (P

The platelet-derived growth factor receptor β (PDGFRB) gene translocations lead to a spectrum of chronic myeloid neoplasms, frequently associated with eosinophilia. Clinical heterogeneity is associated with a molecular one. Here, we report a novel case of a patient harboring a t(5;8)(q33;p22) translocation, resulting in the PCM1/PDGFRB fusion. Conventional cytogenetics and RNA sequencing were performed to identify the chromosomes and the genes involved in the rearrangement, respectively. This study shows that the combination of different strategies is pivotal to fine-tune the diagnosis and the clinical management of the patient. After 1 year of treatment with imatinib, the patient achieves hematological and molecular remission. We present an attractive strategy to identify novel and/or cryptic fusions, which will be relevant for clinicians dealing with the diagnosis of the patients with myelodysplastic syndrome/myeloproliferative diseases with atypical manifestations.

Background A double-blind, placebo-controlled, phase III study (200622) showed that mepolizumab reduces disease flares for patients with uncontrolled FIP1-like-1-platelet-derived growth factor receptor α–negative hypereosinophilic syndrome (HES) and two or more flares in the previous year. Objective To further characterize the safety, clinical benefit, and pharmacodynamics of mepolizumab. Methods Eligible patients from both treatment arms of the double-blind study could enter an open-label extension study (205203; NCT03306043) to receive 4-weekly mepolizumab (300 mg subcutaneously) plus background therapy for 20 weeks. Primary end points were safety-based; other end points included flare rates and changes from baseline in mean daily oral corticosteroid (OCS) dose and blood eosinophil count. Results Of 104 patients who completed the double-blind study, 98% (previous placebo, n = 52; previous mepolizumab, n = 50) enrolled in the open-label extension. Overall, 66 of patients reported adverse events (AEs) (65%), 15 reported treatment-related AEs (15%), and nine reported serious AEs (9%). No events were fatal. The annualized flare rate (95% confidence interval) in the previous placebo and previous mepolizumab groups was 0.37 (0.16-0.86) and 0.14 (0.04-0.49) events/y, respectively. Of 72 patients receiving OCS during weeks 0 to 4, 20 (28%; previous placebo, n = 14; previous mepolizumab, n = 6) achieved 50% or greater reductions in mean daily dose during weeks 16 to 20. At week 20, blood eosinophil count was reduced by 89% in patients previously receiving placebo and remained reduced for those previously receiving mepolizumab. Conclusions Extended mepolizumab treatment was associated with a positive benefit–risk profile. Continued control of disease flares and blood eosinophil counts, plus reductions in OCS use, were observed with mepolizumab in patients with FIP1-like-1-platelet-derived growth factor receptor α–negative HES.

Immunologia; Recerca mèdica Inmunología; Investigación médica Immunology; Medical research Omidubicel (nicotinamide-expanded cord blood) is a potential alternative source for allogeneic hematopoietic cell transplantation (HCT) when an HLA-identical donor is lacking. A phase I/II trial with standalone omidubicel HCT showed rapid and robust neutrophil and platelet engraftment. In this study, we evaluated the immune reconstitution (IR) of patients receiving omidubicel grafts during the first 6 months post-transplant, as IR is critical for favorable outcomes of the procedure. Data was collected from the omidubicel phase I-II international, multicenter trial. The primary endpoint was the probability of achieving adequate CD4+ T-cell IR (CD4IR: > 50 × 106/L within 100 days). Secondary endpoints were the recovery of T-cells, natural killer (NK)-cells, B-cells, dendritic cells (DC), and monocytes as determined with multicolor flow cytometry. LOESS-regression curves and cumulative incidence plots were used for data description. Thirty-six omidubicel recipients (median 44; 13–63 years) were included, and IR data was available from 28 recipients. Of these patients, 90% achieved adequate CD4IR. Overall, IR was complete and consisted of T-cell, monocyte, DC, and notably fast NK- and B-cell reconstitution, compared to conventional grafts. Our data show that transplantation of adolescent and adult patients with omidubicel results in full and broad IR, which is comparable with IR after HCT with conventional graft sources.

PURPOSE Recurrently mutated genes and chromosomal abnormalities have been identified in myelodysplastic syndromes (MDS). We aim to integrate these genomic features into disease classification and prognostication. METHODS We retrospectively enrolled 2,043 patients. Using Bayesian networks and Dirichlet processes, we combined mutations in 47 genes with cytogenetic abnormalities to identify genetic associations and subgroups. Random-effects Cox proportional hazards multistate modeling was used for developing prognostic models. An independent validation on 318 cases was performed. RESULTS We identify eight MDS groups (clusters) according to specific genomic features. In five groups, dominant genomic features include splicing gene mutations ( SF3B1, SRSF2, and U2AF1) that occur early in disease history, determine specific phenotypes, and drive disease evolution. These groups display different prognosis (groups with SF3B1 mutations being associated with better survival). Specific co-mutation patterns account for clinical heterogeneity within SF3B1- and SRSF2-related MDS. MDS with complex karyotype and/or TP53 gene abnormalities and MDS with acute leukemia–like mutations show poorest prognosis. MDS with 5q deletion are clustered into two distinct groups according to the number of mutated genes and/or presence of TP53 mutations. By integrating 63 clinical and genomic variables, we define a novel prognostic model that generates personally tailored predictions of survival. The predicted and observed outcomes correlate well in internal cross-validation and in an independent external cohort. This model substantially improves predictive accuracy of currently available prognostic tools. We have created a Web portal that allows outcome predictions to be generated for user-defined constellations of genomic and clinical features. CONCLUSION Genomic landscape in MDS reveals distinct subgroups associated with specific clinical features and discrete patterns of evolution, providing a proof of concept for next-generation disease classification and prognosis.

Introduction: Commonly accepted standardized sets of outcomes to be measured in clinical trials are still limited. In accordance, outcome measures vary widely between clinical trials even within defined hematological malignancy (HM) entities. Definition of a core outcome set (COS), which represents a standardized agreed set of outcomes that should be measured and reported in all trials for the respective disease of interest may improve this situation. Furthermore, respective COS should address the need of all stakeholders, i.e. not only the views of physicians and industry running the trials, but also the interests of patients and regulators. To perform a task like this, HARMONY - Healthcare Alliance for Resourceful Medicine Offensive against Neoplasms in Hematology - a private-public partnership established in January 2017, including 53 partners and 43 associated partners in 18 different European countries and also 6 patient organizations, poses an optimal platform to define COS for HMs. Methods: To define COS for 5 selected HMs, it was decided to use the Delphi survey method provided by COMET initiative. Since HARMONY has members of several important stakeholder groups (clinicians, industry, health authorities and patient groups) it was decided to include all stakeholders to participate in the Delphi surveys. A pilot study was implemented for the COS for acute myeloid leukemia (AML) based on which additional Delphi surveys were developed for myelodysplastic syndrome (MDS), non-Hodgkin lymphoma (NHL), multiple myeloma (MM), and chronic lymphocytic leukemia (CLL). As starting point preliminary outcome lists were generated based on published reports and available guidelines. Surveys were performed with representatives from each stakeholder group to agree within a pre-defined and iterative process on a COS for each HM. Conditions and criteria were defined in study protocols. Each outcome was rated into 3 categories (1-3 "not important", 4-6 "important but not critical" and 7-9 "critical"). A "consensus-in criterion" was defined if 70 % or more respondents scored the outcome as critically important (7-9) and 15% or fewer rated the outcome as limited important (1-3). To make sure that the patients' voice was heard within the consensus process, a special "patient-important criterion" had been implemented during data analysis. Outcomes ranked with a median of 7 or higher in the patient group were highlighted, showing these are really important for patients. According to a bottom-up-approach, an overarching COS was then created based on the individual survey results. Results: For the Delphi surveys a total of 365 individuals participated including 126 clinicians (35%), 46 EFPIA members (13%), 177 patients/patient advocates (48%) and 16 regulators (4%). While there was a large overlap of outcomes among HMs, there were also many disease specific outcomes such as leukemia-free survival (LFS) for AML, very good partial response (VGPR) for MM to name only few. In addition, there were sometimes major differences in the assessment of individual stakeholders within an outcome, e.g. between clinicians and patients. Finally, the general COS applicable to all HMs included core outcomes that met the consensus-in criterion for all HMs. Conclusion: Using Delphi surveys to define specific COS for HMs revealed meaningful results. Based on the bottom-up-approach not only disease specific HM COS could be defined, but also an overarching COS applicable to all HMs. This overarching COS will subsequently not only allow to compare results more easily within a distinct HM subgroup but also results across different HMs. To our knowledge, this is the first multidisciplinary approach to define COS across four different stakeholder groups. These COS should now be a starting point to further refine COS and to apply them within future clinical trials, thereby reducing inconsistencies and bias in outcome-reporting. Results of COS based clinical trials will simplify the development of novel clinical recommendations, which will improve future patient management and clinical patient care in the real-world setting.

Contains fulltext : 237720.pdf (Publisher’s version ) (Open Access) We present a noninvasive Web-based app to help exclude or diagnose myelodysplastic syndrome (MDS), a bone marrow (BM) disorder with cytopenias and leukemic risk, diagnosed by BM examination. A sample of 502 MDS patients from the European MDS (EUMDS) registry (n > 2600) was combined with 502 controls (all BM proven). Gradient-boosted models (GBMs) were used to predict/exclude MDS using demographic, clinical, and laboratory variables. Area under the receiver operating characteristic curve (AUC), sensitivity, and specificity were used to evaluate the models, and performance was validated using 100 times fivefold cross-validation. Model stability was assessed by repeating its fit using different randomly chosen groups of 502 EUMDS cases. AUC was 0.96 (95% confidence interval, 0.95-0.97). MDS is predicted/excluded accurately in 86% of patients with unexplained anemia. A GBM score (range, 0-1) of less than 0.68 (GBM < 0.68) resulted in a negative predictive value of 0.94, that is, MDS was excluded. GBM ≥ 0.82 provided a positive predictive value of 0.88, that is, MDS. The diagnosis of the remaining patients (0.68 ≤ GBM < 0.82) is indeterminate. The discriminating variables: age, sex, hemoglobin, white blood cells, platelets, mean corpuscular volume, neutrophils, monocytes, glucose, and creatinine. A Web-based app was developed; physicians could use it to exclude or predict MDS noninvasively in most patients without a BM examination. Future work will add peripheral blood cytogenetics/genetics, EUMDS-based prospective validation, and prognostication.

Cellular and humoral response to acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) infections is on focus of research. We evaluate herein the feasibility of expanding virus‐specific T cells (VST) against SARS‐CoV‐2 ex vivo through a standard protocol proven effective for other viruses. The experiment was performed in three different donors' scenarios: (a) SARS‐CoV‐2 asymptomatic infection/negative serology, (b) SARS‐CoV‐2 symptomatic infection/positive serology, and (c) no history of SARS‐CoV‐2 infection/negative serology. We were able to obtain an expanded VST product from donors 1 and 2 (1.6x and 1.8x increase of baseline VST count, respectively) consisting in CD3 + cells (80.3% and 62.7%, respectively) with CD4 + dominance (60% in both donors). Higher numbers of VST were obtained from the donor 2 as compared to donor 1. T‐cell clonality test showed oligoclonal reproducible peaks on a polyclonal background for both donors. In contrast, VST could be neither expanded nor primed in a donor without evidence of prior infection. This proof‐of‐concept study supports the feasibility of expanding ex vivo SARS‐CoV‐2‐specific VST from blood of convalescent donors. The results raise the question of whether the selection of seropositive donors may be a strategy to obtain cell lines enriched in their SARS‐CoV‐2‐specificity for future adoptive transfer to immunosuppressed patients., The neutralization antibody assay was supported by Valencian government grant Covid_19-SCI as well as the Spanish National Research Council grants CSIC-COV19-082 and CSIC-COV-19-104 to RG.
