Introduction: In recent years, defibrotide (DFT) has emerged as a promising therapy for veno-occlusive disease (VOD). The aim of this study was to investigate whether DFT prophylaxis affects neutrophil engraftment in patients undergoing hematopoietic stem cell transplantation (HSCT).
Methods: A cohort of 44 consecutive pediatric patients who underwent HSCT was retrospectively analyzed to see the role of DFT on engraftment. Patients were assigned into two groups based on the use or non-use of prophylaxis with DFT.
Results: The mean time to engraftment was statistically different between the two groups for both polymorphonuclear neutrophils (PMN) and white blood cells.
Conclusion: Our study supports the hypothesis that prophylaxis with DFT for VOD leads to a delay to the engraftment of PMN in pediatric patients that underwent HSCT.

Severe acute graft-versus-host disease (GVHD) can occur during allogeneic hematopoietic stem cell transplantation (allo-HSCT), causing considerable morbidity and mortality. Although several biomarkers have been reported for predicting acute GVHD, they are often difficult to measure in routine clinical practice. Recently, three-dimensional computed tomography (3D-CT) has been used to quantify the detailed bronchial structure, which might correlate with acute GVHD.

Senescence is a non-proliferative, survival state that cancer cells can enter to escape therapy. In addition to soluble factors, senescence cells secrete extracellular vesicles (EVs), which are important mediators of intercellular communication. To explore the role of senescent cell-derived EVs (senEVs) in inflammatory responses to senescence, we developed an engraftment-based senescence model in wild-type mice and genetically blocked senEV release in vivo, without significantly affecting soluble mediators.

Background: Despite decades of post-allogeneic hematopoietic cell transplantation (HCT) growth factor utilization, its role remains undefined, leading to ongoing debates and research. The theoretical impacts of growth factors have been challenged in numerous studies.
Methods: In this retrospective cohort study conducted at the Princess Margaret Cancer Centre, we analyzed the clinical outcomes of 509 patients who underwent allogeneic HCT between May 1, 2019, and May 31, 2022.

Importance: Although sharing care with local oncologists after allogeneic hematopoietic cell transplantation (HCT) has been proposed for patients living far from HCT centers, it is not known whether a shared strategy is safe or improves patient quality of life (QOL).
Objective: To determine the efficacy and safety of sharing follow-up care after HCT between the HCT specialty center and local oncologists.
Design, Setting, And Participants: This was a multicenter collaborative randomized clinical trial of patients undergoing HCT at Dana-Farber Cancer Institute (DFCI)-a high volume HCT center in Boston (Massachusetts)-and 8 local oncology practices.

A 54-year-old woman underwent cord blood transplantation in second remission of acute myeloid leukemia. She tested positive for anti-toxoplasma IgG antibody before transplantation. After neutrophil engraftment, she complained of foggy vision, but brain MRI showed no abnormality.
