INFVA is an important cause of pulmonary infections in patients receiving BMT, and is associated with considerable morbidity and mortality for a readily preventable and treatable infection. Few studies have addressed the impact of the new neuraminidase inhibitors in the prognosis of influenza after BMT. The aim of this study is to assess the impact of oseltamivir on the control of INFVA infection in BMT recipients. INFVA was screened in NPA and/or bronchoalveolar lavage using IF in all BMT recipients having respiratory symptoms. Three URTI and one associated upper and LRTI were diagnosed in three BMT recipients out of six patients admitted to the BMT unit, during eight-wk period (March and April 2008). All patients having INFVA respiratory infection were treated by oral oseltamivir 60 mg/day, begun more than 48 h after symptom onset. Respiratory symptoms disappeared within a mean of 60 h (48-96 h) of treatment. However, viral tests had remained positive for 8-39 days. Outside the initial associated URTI and LRTI, no further viral pneumonia occurred. No patient died of INFVA. Oseltamivir was well tolerated outside vomiting during the first three days of treatment in one patient. Oseltamivir appears to play an important role in the outcome of INFVA infection as well in URTI as in severe LRTI in patients receiving BMT.

Division of Bone Marrow Transplantation and Immune Deficiency, Cincinnati Children's Hospital Medical Center, Cincinnati, OH; Department of Pediatrics, University of Cincinnati, Cincinnati, OH.
Background: HSCT conditioning regimens cause massive lysis of hematopoietic cells with release of toxic intracellular molecules into the circulation.
Objectives: To describe the response to oxidative stress early after hemopoietic stem cell transplantation (HSCT) and assess the association of early oxidative stress with later transplant outcomes.
Study Design: Key components of in the body's physiological response to oxidative stress were studied in a cohort of 122 consecutive pediatric allogeneic HSCT recipients.
Enhanced Costimulation Blockade With αCD154, αCD2, and αCD28 to Promote Heart Allograft Tolerance in Nonhuman Primates.

Background: Long-term renal allograft acceptance has been achieved in macaques using a transient mixed hematopoetic chimerism protocol, but similar regimens have proven unsuccessful in heart allograft recipients unless a kidney transplant was performed simultaneously. Here, we test whether a modified protocol based on targeting CD154, CD2, and CD28 is sufficient to prolong heart allograft acceptance or promote the expansion of regulatory T cells.
Methods: Eight macaques underwent heterotopic allo-heart transplantation from major histocompatibility complex-mismatched donors.
Donor Type Does Not Impact Late Graft Failure Following Reduced Intensity Allogeneic Hematopoietic Cell Transplantation with Post-Transplant Cyclophosphamide Based Graft-Versus-Host Disease Prophylaxis.

Dana-Farber Cancer Institute, Division of Transplantation and Cellular Therapy, Boston, MA. Electronic address:
Background: Post-transplant cyclophosphamide (PTCy) is a commonly used graft-vs-host disease (GVHD) prophylaxis, particularly in the setting of haploidentical (haplo) hematopoietic cell transplantation (HCT). The rate of graft failure has been reported to be as high as 12-20% in haplo-HCT recipients using PTCy. The objective of this study was to determine if donor type influenced the risk of late graft failure following RIC HCT using PTCy-based GVHD prophylaxis.

Introduction: Posttransplant cyclophosphamide (PTCy) has revolutionized the landscape of human leukocyte antigen (HLA)-haploidentical hematopoietic cell transplantation (haplo-HCT), providing a pivotal therapeutic option for patients with hematological malignancies who lack an HLA-matched donor.
Methods: In this retrospective analysis involving 54 adult patients undergoing PTCy-based haplo-HCT, we evaluated the impact of inhibitory killer immunoglobulin-like receptor (KIR)/HLA mismatch, alongside patient, donor, and transplant factors, on clinical outcomes within a homogeneous cohort characterized by a myeloablative conditioning regimen and bone marrow graft.
Results: With a median follow-up of 73.
A role for diet and gut microbiota metabolites in autologous hematopoietic cell transplant recipients.
Blood Cell Ther
November 2024
Clinical Hematology & Medical Oncology.
Introduction: The gut microbiome has an established role in allogeneic hematopoietic cell transplantation (allo-HCT), but not in an auto-HCT setting. We have hypothesized that fecal short-chain fatty acids (SCFA) and urinary 3-indoxyl sulfate (3-IS), which are metabolites derived from the action of the gut microbiome on dietary fiber, play a role in auto-HCT outcomes.
Methods: This was a single-center prospective study involving auto-HCT recipients.
