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.

Nursing care for chimeric antigen receptor T cell therapy survivors: A literature review.

Chimeric antigen receptor T cell (CAR-T) therapy is an immunotherapy that involves genetically modifying the patient's own T cells to express a chimeric antigen receptor, enabling them to recognize and destroy cancer cells. This treatment has revolutionized the prognosis and management of hematological malignancies, leading to a significant increase in long-term survivors. However, there is limited evidence regarding late sequelae and post-treatment care due to the recent emergence of this therapy.

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.

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.

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.

Easix Score Correlates With Endothelial Dysfunction Biomarkers and Predicts Risk of Acute Graft-Versus-Host Disease After Allogeneic Transplantation.

Plasma biomarkers of endothelial dysfunction have been postulated for the diagnosis and prognosis of acute graft-versus-host disease (aGVHD). However, their use is not validated in clinical practice yet. The endothelial activation and stress index (EASIX), a simple score based on routine laboratory parameters, is considered to be an indirect marker of endothelial damage.

Impact of letermovir prophylaxis in CMV reactivation and disease after allogenic hematopoietic cell transplantation: a real-world, observational study.

Letermovir for CMV prevention in CMV-seropositive adults undergoing allo-HCT was implemented at our program in 2021. This study investigates the results from the use of letermovir. The study includes all the 140 CMV-seropositive patients who underwent an allo-HCT during the years 2020, 2021, and 2022 at our institution.

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.

Applicability and validation of different prognostic scores in allogeneic hematopoietic cell transplant (HCT) in the post-transplant cyclophosphamide era.

We investigated the predictive capacity of six prognostic indices [Karnofsky Performance Status (KPS), Hematopoietic Cell Transplant-Specific Comorbidity Index (HCT-CI), Disease Risk Index (DRI), European Bone Marrow Transplantation (EBMT) and Revised Pre-Transplantation Assessment of Mortality (rPAM) Scores and Endothelial Activation and Stress Index (EASIX)] in 205 adults undergoing post-transplant cyclophosphamide (PTCy)-based allo-HCT. KPS, HCT-CI, DRI and EASIX grouped patients into higher and lower risk strata. KPS and EASIX maintained appropriate discrimination for OS prediction across the first 2 years after allo-HCT [receiver operating characteristic curve (area under the curve (AUC) > 55 %)].

Effect of CD34 Cell Dose on the Outcomes of Allogeneic Stem Cell Transplantation with Post-Transplantation Cyclophosphamide.

The impact of infused CD34 cell dose on outcomes after allogeneic hematopoietic stem cell transplantation (alloHSCT) using standard graft-versus-host disease (GVHD) prophylaxis remains controversial. Information on this subject is scarce for alloHSCT using high-dose post-transplantation cyclophosphamide (PTCy). We aimed to assess the effect of CD34 cell dose in peripheral blood stem cell (PBSC) grafts on the outcome of alloHSCT using PTCy-based GVHD prophylaxis.

Incidence, risk factors, and impact of early cardiac toxicity after allogeneic hematopoietic cell transplant.

This study investigates early cardiac events (ECEs) occurring during the first 180 days after allogeneic hematopoietic cell transplant (allo-HCT) in 416 adults receiving posttransplant cyclophosphamide (PTCY) (n = 258) or not receiving PTCY (n = 158). Total body irradiation (TBI) was given to 133 (31.9%) patients, of whom 111 (83.

Bacterial Bloodstream Infections in Patients Undergoing Allogeneic Hematopoietic Cell Transplantation With Post-Transplantation Cyclophosphamide.

This study investigates the incidence and predictors for bacterial bloodstream infection (BSI) in 330 adults undergoing allo-HCT, and explores the effect of post-transplantation cyclophosphamide (PTCY) on the probability of presenting this complication. All patients received levofloxacin during the aplastic phase. Only the first episode of BSI was counted as an event.

PTCY and Tacrolimus for GVHD Prevention for Older Adults Undergoing HLA-Matched Sibling and Unrelated Donor AlloHCT.

The use of post-transplantation cyclophosphamide (PTCY) for graft-versus-host disease (GHVD) prevention is becoming prevalent in the transplantation community when HLA-identical sibling and 10/10 HLA-matched (MUD) and 9/10 mismatched unrelated donors are selected for alloHSCT. However, reported evidence on outcomes from elderly patients receiving PTCY-containing GVHD prophylaxis remains limited. This study aims to compare the outcomes of PTCY- tacrolimus (TK) prophylaxis and conventional GVHD prophylaxis in patients aged >50 years undergoing peripheral blood alloHSCT from a single institution.

An endothelial proinflammatory phenotype precedes the development of the engraftment syndrome after autologous Hct.

Engraftment syndrome (ES) is a common complication after autologous hematopoietic cell transplantation (auto-HCT) whose pathophysiological substrate remains unclear. We investigated whether endothelial damage could contribute to ES. Circulating ECs-damage biomarkers were measured in plasma from patients with (ES; n = 14) or without ES (non-ES; n = 20), collected at different time points: before HCT, 5 (S5) and 10 days (S10) after HCT, and at either the ES onset (SON) or the discharge day (SDIS).

Impact of severe acute kidney injury and chronic kidney disease on allogeneic hematopoietic cell transplant recipients: a retrospective single center analysis.

Acute kidney injury (AKI) increases early mortality in allogeneic hematopoietic cell transplant (allo-HCT) recipients and may accelerate chronic kidney disease (CKD) development. We analyzed prospective variables related to AKI and CKD in 422 allo-HCT recipients to establish risk factors of severe acute renal failure and CKD. Renal function and creatinine were periodically assessed from baseline till the last follow-up.

A reproducible and safe at-home allogeneic haematopoietic cell transplant program: first experience in Central and Southern Europe.

In 2015, we implemented an at-home allogeneic haematopoietic cell transplant (allo-HCT) program. Between 2015 and 2018, 252 patients underwent allo-HCT; 41 patients underwent allo-HCT in the at-home program (46% myeloablative; 63% unrelated donor; 32% posttransplant cyclophosphamide), and these patients were compared with 39 in-patients; safety, capacity to release beds for other programs, and economic efficiency cost were evaluated. We observed a lower incidence of febrile neutropenia in the at-home group compared with that in the in-patient group (32% versus 90%; p < 0.

Improving security of autologous hematopoietic stem cell transplant in patients with light-chain amyloidosis.

Autologous stem cell transplant (ASCT) has demonstrated to be an effective treatment for patients with light-chain (AL) amyloidosis. However, a high transplant-related mortality (TRM) rate was reported in previous series of patients and questioned the role of transplant in this disease. Recently, experienced groups have shown a significant TRM decrease that has been attributed to an accurate selection of patients.
