Patients received grafts from HLA-matched donors (47.4%), mismatched unrelated donors (MMUD, 33.

At-home autologous hematopoietic cell transplant for adults with hematological malignancies. How frailty impacts and evolves during HCT procedure. An observational, longitudinal, and prospective study.

Introduction And Aims: Since April 2021, the frailty state of patients is evaluated routinely in adults undergoing auto-HCT at our institution using the HCT Frailty Scale. The scale categorises each candidate as either fit, pre-fit or frail.

Methods: Our study includes 80 consecutive adults with lymphoprolipherative disorders (LPD) and multiple myeloma (MM) undergoing at-home auto-HCT at our institution between June 2021 and June 2023.

Blueprint for a Catalan Apheresis Database Initiative: The Catalan Apheresis Therapeutics Network and Its Role in Supporting Health Administration Planning.

The Therapeutic Apheresis Database in the Catalan Region (AfTerCat) was developed to consolidate and standardize data collection for therapeutic apheresis procedures across public and private institutions in Catalonia. Covering procedures performed from 2019 to 2023 in 21 apheresis units, the registry captures data on plasma treatments, cell therapies, and cytapheresis procedures, with over 26,000 recorded entries. Variations in workload across public and private institutions were noted, influencing resource needs and operational costs.

Real-world evidence of Carfilzomib, Lenalidomide and Dexamethasone (KRD) Scheme in patients with relapsed / refractory multiple myeloma.

Carfilzomib, lenalidomide and dexamethasone (KRd) is still a widely used treatment option for patients with relapsed / refractory multiple myeloma (RRMM). However, there is limited real-world evidence. Here we evaluated the efficacy and safety of KRd in patients with RRMM treated following the standard clinical practice of the hospitals in the Catalan region.

Bilirubin Removal with Therapeutic Plasma Exchange or Molecular Adsorbent Recirculating System as Treatment for Cholemic Nephropathy in Patients with Cirrhosis and Acute-on-Chronic Liver Failure: A Case Series.

Introduction: Cholemic nephropathy is an overlooked cause of acute kidney injury (AKI) in patients with cirrhosis and high bilirubin plasma levels (usually above 20 mg/dL), due to bilirubin and bile acid deposition in the kidneys. Those deposits have been hypothesized to cause tubular injury. It has no standardized diagnostic criteria or therapeutic strategies.

Effectiveness of oral platelet lysate gel to treat oral mucosal manifestations associated with chronic graft versus host disease.

Background: Chronic graft-vs-host disease (cGvHD) is a severe immune-mediated complication that affects patients following allogeneic hematopoietic stem cell transplantation (allo-HSCT). Oral manifestations of cGvHD, such as ulcers and mucosal inflammation, significantly impair quality of life and often require long-term treatment. Existing therapies provide limited relief, prompting the exploration of new approaches, including the use of autologous platelet lysate (PL) gel for its regenerative properties.

Optimized GVHD Prevention in HLA-Mismatched Unrelated Allogeneic HCT Using a PTCY-Based Approach.

Although post-transplant cyclophosphamide (PTCY)-based prophylaxis has become a widely adopted strategy for preventing graft-versus-host disease (GVHD) in 9 out of 10 HLA-mismatched unrelated donors (MMUDs), allogeneic hematopoietic cell transplants (allo-HCTs), data on the safety and efficacy of PTCY in this setting remain limited. This single-center study investigates the outcomes of 94 adults with hematological malignancies undergoing MMUD allo-HCT with PTCY and tacrolimus (Tac) (PTCY-Tac) between 2014 and 2023. The median age was 53 years, and 60.

Chronic myelomonocytic leukemia with NPM1 mutation or acute myeloid leukemia?

The 2022 WHO revision and the ICC classification have recently modified the diagnostic criteria for chronic myelomonocytic leukemia (CMML) and acute myeloid leukemia. However, there is no consensus on whether CMML with NPM1 mutation (NPM1mut) should be diagnosed as AML. Nowadays, it is a subject of discussion because of its diagnostic and therapeutic implications.

Outcomes of older adults undergoing allogeneic hematopoietic cell transplantation with post-transplant cyclophosphamide based prophylaxis.

This study evaluates the feasibility of using post-transplant cyclophosphamide (PTCY) prophylaxis in allo-hematopoietic cell transplantation (HCT) for adults aged 65 and older. PTCY is increasingly used to prevent graft-versus-host disease (GVHD) across all donor types, but concerns remain about potential risks, especially in older patients. Fifty-seven adults aged 65 or older with hematological malignancies, undergoing their first allo-HCT with PTCY prophylaxis between January 2011 and January 2023 were included.

Safety and efficacy of G-CSF after allogeneic hematopoietic cell transplantation using post-transplant cyclophosphamide: clinical and in vitro examination of endothelial activation.

Since 2021 the use of G-CSF was implemented in allo-HCT with PTCY-based prophylaxis with the aim of shortening the aplastic phase and reducing infectious complications. This study investigates the effectiveness of this change in protocol performed at our institution. One-hundred forty-six adults undergoing allo-HCT with PTCY-based prophylaxis were included, and among them, 58 (40%) received G-CSF.

Reduced Dose of Post-Transplant Cyclophosphamide with Tacrolimus for the Prevention of Graft-versus-Host Disease in HLA-Matched Donor Peripheral Blood Stem Cell Transplants: A Prospective Pilot Study.

PTCY 50 mg/kg/day on days +3/+4 is an excellent strategy to prevent GVHD. However, its use is associated with adverse outcomes such as delayed engraftment, increased risk of infection, and cardiac complications. This pilot study evaluates the efficacy and toxicity of a reduced dose of PTCY (40 mg/kg/day) combined with tacrolimus in 22 peripheral blood HLA-matched alloHSCT patients.

Evaluation of European LeukemiaNet 2022 risk classification in patients undergoing allogeneic haematopoietic stem cell transplantation for acute myeloid leukaemia: Identification of a very poor prognosis genetic group.

European LeukemiaNet refined their risk classification of acute myeloid leukaemia (AML) in 2022 (ELN 2022) according to the two new myeloid classifications published the same year. We have retrospectively assessed the prognostic value of the ELN 2022 in 120 AML patients undergoing allogeneic haematopoietic cell transplantation (allo-HCT), including 99 in first complete response (CR1) from 2011 to 2021 in our centre. Adverse risk patients (Adv) presented inferior outcome in terms of overall survival (OS) and leukaemia-free survival (LFS) (OS [p = 0.

Increased Serum Levels of N-terminal pro-B-type Natriuretic Peptide (NT-proBNP) in Mobilized Healthy Donors with G-CSF: A Cohort Study.

Limited data regarding elevation of N-terminal pro-B-type natriuretic peptide (NT-proBNP) in mobilized donors with G-CSF is available. We extended these findings by examining serum NT-proBNP in a cohort study including 35 healthy donors and 69 patients who received G-CSF for CD34+ mobilization as well as 54 patients who did not receive G-CSF but who underwent collection of CD3+ cells for chimeric antigen receptor (CAR) T-cell manufacturing. No donor in the three cohorts experienced significant cardiac adverse events.

EASIX and cardiac adverse events after allogeneic hematopoietic cell transplantation.

This study investigates the interaction between endothelial activation, indirectly measured using EASIX, and the probability of presenting cardiac adverse events (CAE) during the first year after allo-HCT. The 437 consecutive adults undergoing PB allo-HCT from 2012 and 2021 were included. EASIX was retrospectively calculated before and during the first 6 months after allo-HCT and transformed to log2-base to conduct the statistical analysis.

Therapeutic efficacy and safety of pathogen-reduced platelet components: Results of a meta-analysis of randomized controlled trials.

Background And Objectives: Clinical efficacy and safety of pathogen-reduced platelet concentrates (PR-PCs) concerning bleeding prevention are still debated despite conclusive real-world data from multiple countries where PR-PCs are transfused routinely. We performed a meta-analysis of randomized controlled trials (RCTs) comparing the clinical efficacy and safety of conventional platelet components (PCs) and PR-PCs prepared with the amotosalen/ultraviolet A light (INTERCEPT platelet concentrate [I-PC]) or riboflavin/ultraviolet light (Mirasol platelet concentrate [M-PC]) technologies, transfused in thrombocytopenic adult patients.

Materials And Methods: A literature search was conducted, and 10 RCTs met the criteria for inclusion in this meta-analysis.

Post-Transplantation Cyclophosphamide and Tacrolimus for Graft-versus-Host Disease Prevention after Allogeneic Hematopoietic Cell Transplantation from HLA-Matched Donors Has More Advantages Than Limitations.

This study compared the efficacy of graft-versus-host disease (GVHD) prophylaxis with post-transplantation cyclophosphamide (PTCy) and tacrolimus (Tac) versus other regimens in 272 adults undergoing peripheral blood (PB) allogeneic hematopoietic cell transplantation (allo-HCT) from HLA-matched donors. Of these 272 patients, 95 (34.9%) received PTCy/Tac.

Endothelial Activation and Stress Index in adults undergoing allogeneic hematopoietic cell transplantation with post-transplant cyclophosphamide-based prophylaxis.

Background Aims: Post-transplant cyclophosphamide (PTCY)-based prophylaxis is becoming widespread for allogeneic hematopoietic cell transplantation (allo-HCT) performed independently of the selected donor source. In parallel, use of the Endothelial Activation and Stress Index (EASIX)-considered a surrogate parameter of endothelial activation-for predicting patient outcomes and clinical complications is gaining popularity in the allo-HCT setting.

Methods: We first investigated whether the dynamics of EASIX after allo-HCT differ between patients receiving PTCY and patients receiving other prophylaxis.
