Community-Acquired Respiratory Virus Infections: A Threat to Long-Term survivors after Allogeneic Stem Cell Transplant?

Background: Studies on late community-acquired respiratory virus (CARV) infections in long-term allogeneic hematopoietic stem cell transplantation (allo-HCT) survivors are scarce, creating knowledge gaps on the epidemiology, risk of progression to lower respiratory tract disease (LRTD), and conditions linked to poor outcomes.

Patients And Methods: We included consecutive CARV infection episodes occurring up to six months after allo-HCT registered in our database from December 2013 to June 2023 at two Spanish transplant centers.

Results: Among 426 allo-HCT recipients, 1070 CARV episodes were recorded, 791 (74%) with only upper respiratory tract disease (URTD) and 279 (15%) progressing to LRTD, at a median of 18.

Evaluation and management of hepatic dysfunction, portal hypertension and portal/splanchnic vein thrombosis in patients with myelofibrosis undergoing allogeneic haematopoietic cell transplantation: A practice based survey on behalf of the Chronic Malignancies Working Party of the EBMT.

Heterogeneous approaches exist in regard to the management of disease-related co-morbidities in potential allogeneic haematopoietic cell transplantation (allo-HCT) candidates with myelofibrosis (MF). The EBMT Chronic Malignancies Working Party launched an electronic survey to evaluate how MF-specific comorbidities are approached and whether they ultimately affect the decision to transplant. A total of 41/63 (65%) Centers, all of whom were experienced in the management of MF allo-HCT, responded.

Navigating 'grey areas' and challenges during evaluation of transplant eligibility in specific myelofibrosis populations: a perspective on behalf of the Chronic Malignancies Working Party of the EBMT.

Significant efforts have been made to effectively select myelofibrosis (MF) patients who can benefit from allogeneic hematopoietic cell transplantation (allo-HCT), the only current cure for MF. The recent EBMT/ELN 2024 recommendations offer valuable guidance for hematologists and transplant physicians. However, several grey areas remain in day-to-day clinical practice regarding the feasibility and optimal preparation for transplantation in patients with this disease.

Anti-CD19 CAR-T Cell Therapy in Elderly Patients: Multicentric Real-World Experience from GETH-TC/GELTAMO.

Chimeric antigen receptor (CAR)-T cell therapy is approved for the treatment of relapsed/refractory (R/R) large B cell lymphoma (LBCL). However, elderly patients might not be candidates for this therapy due to its toxicity, and criteria for candidate selection are lacking. Our aim was to analyze efficacy and toxicity results of CAR-T cell therapy in the population of patients 70 years and older as compared to those obtained in younger patients in the real-world setting.

EEG before chimeric antigen receptor T-cell therapy and early after onset of immune effector cell-associated neurotoxicity syndrome.

Background: Immune effector cell-associated neurotoxicity syndrome (ICANS) is common after chimeric antigen receptor T-cell (CAR-T) therapy.

Objective: This study aimed to assess the impact of preinfusion electroencephalography (EEG) abnormalities and EEG findings at ICANS onset for predicting ICANS risk and severity in 56 adult patients with refractory lymphoma undergoing CAR-T therapy.

Study Design: EEGs were conducted at the time of lymphodepleting chemotherapy and shortly after onset of ICANS.

Outcome of Human Parainfluenza Virus infection in allogeneic stem cell transplantation recipients: possible impact of ribavirin therapy.

Background: This retrospective study focused on analyzing community-acquired respiratory virus (CARV) infections, in particular human parainfluenza virus (hPIV) after allogeneic stem cell transplant (allo-SCT) in adults recipients. It aimed to assess the impact of ribavirin treatment, clinical characteristics, and risk factors associated with lower respiratory tract disease (LRTD) progression and all-cause mortality.

Patients And Methods: The study included 230 allo-SCT recipients diagnosed with hPIV between December 2013 and June 2023.

Essential thrombocythaemia: A contemporary approach with new drugs on the horizon.

Essential thrombocythaemia (ET) is a myeloproliferative neoplasm characterized by an increased risk of vascular complications and a tendency to progress to myelofibrosis and acute leukaemia. ET patients have traditionally been stratified into two thrombosis risk categories based on age older than 60 years and a history of thrombosis. More recently, the revised IPSET-thrombosis scoring system, which accounts for the increased risk linked to the JAK2 mutation, has been incorporated into most expert recommendations.

Treosulfan compared to busulfan in allogeneic haematopoietic stem cell transplantation for myelofibrosis: a registry-based study from the Chronic Malignancies Working Party of the EBMT.

We aimed to compare outcomes following treosulfan (TREO) or busulfan (BU) conditioning in a large cohort of myelofibrosis (MF) patients from the EBMT registry. A total of 530 patients were included; 73 received TREO and 457 BU (BU ≤ 6.4 mg/kg in 134, considered RIC, BU > 6.

Allogeneic haematopoietic cell transplantation for advanced systemic mastocytosis: Best practice recommendations on behalf of the EBMT Practice Harmonisation and Guidelines Committee.

Systemic Mastocytosis (SM) is a multifaceted clinically heterogeneous disease. Advanced SM (AdvSM) comprises three entities: aggressive SM (ASM), mast cell leukaemia (MCL) and SM with an associated hematologic neoplasm (SM-AHN), the latter accounting for 60-70% of all AdvSM cases. Detection of a disease-triggering mutation in the KIT gene (esp.

Impact of comorbidities and body mass index on the outcomes of allogeneic hematopoietic cell transplantation in myelofibrosis: A study on behalf of the Chronic Malignancies Working Party of EBMT.

Investigating the evaluation of eligibility for transplant in myelofibrosis (MF): The role of HCT-CI and BMI. HCT-CI emerges as a key prognostic factor, while BMI shows limited impact. This study expands insights for better clinical decision-making in MF allo-HCT.

Genomic classification and outcomes of young patients with polycythemia vera and essential thrombocythemia according to the presence of splanchnic vein thrombosis and its chronology.

To elucidate the role of splanchnic vein thrombosis (SVT) and genomic characteristics in prognosis and survival, we compared patients with polycythemia vera (PV) or essential thrombocythemia (ET) presenting SVT at diagnosis (n = 69, median age 43 years) or during follow-up (n = 21, median age 46 years) to a sex- and age-matched control group of PV/ET without SVT (n = 165, median age 48 years). The majority of patients presenting with SVT at diagnosis were classified as myeloproliferative neoplasm with heterozygous JAK2 mutation (87% of cases vs. 69% in PV/ET control group, p < 0.

Indication and management of allogeneic haematopoietic stem-cell transplantation in myelofibrosis: updated recommendations by the EBMT/ELN International Working Group.

New options for medical therapy and risk scoring systems containing molecular data are leading to increased complexity in the management of patients with myelofibrosis. To inform patients' optimal care, we updated the 2015 guidelines on indications for and management of allogeneic haematopoietic stem-cell transplantation (HSCT) with the support of the European Society for Blood and Marrow Transplantation (EBMT) and European LeukemiaNet (ELN). New recommendations were produced using a consensus-building methodology after a comprehensive review of articles released from January, 2015 to December, 2022.
