PURPOSE Determinants of allogeneic blood use in cardiac surgery include preoperative factors such as female sex, age, body weight, hematocrit and red cell volume. We verified if these variables also predicted the need for allogeneic transfusions when autologous blood is predonated. METHODS Demographic and intraoperative variables, hemoglobin concentrations and transfusion requirements in pati...

T cell responses to MHC-mismatched transplants can be mediated via direct recognition of allogeneic MHC molecules on the cells of the transplant or via recognition of allogeneic peptides presented on the surface of recipient APCs in recipient MHC molecules - a process known as indirect recognition. As CD4(+)CD25(+) Tregs play an important role in regulating alloresponses, we investigated whethe...

Mesenchymal stem cells (MSC) are multipotential cells with utility in tissue engineering and regenerative medicine. However, the immunological properties and immunogenicity of allogeneic MSC remain poorly defined. Recent studies investigating their immunogenicity remain inconclusive and this has hampered their clinical application. This study investigated the (1) immunogenicity and (2) immunomo...

Introduction. The question of the possibility recovery postischemic myocardium remains relevant. Aim. aim study was to effect dispersed decellularized allogeneic extracellular matrix (allogeneic biomaterial, DAB) on developed fibrous degeneration myocardium, as well reveal possible mechanisms cellular regeneration. Materials and methods. muscular wall heart rats subjected cryodestruction. After...

To gain further insights in the pathogenesis of herpesvirus pneumonia in allogeneic bone marrow transplant recipients, transplanted mice (B10.BR = CBA) with graft-versus-host disease (GVHD) and control mice (transplanted mice without GVHD and normal CBA mice) were infected intranasally with herpes simplex virus type 1 (HSV-1). When compared with infected control mice, infected allogeneic transp...

Allogeneic blood transfusion results in the infusion into the recipient of large amounts of foreign antigens in both soluble and cell-associated forms. The persistence of these antigens in the circulation of the recipient may create conditions that allow the development of immune down-regulation. Evidence from a variety of sources indicates that allogeneic blood transfusion enhances the surviva...

Differentiating thrombotic thrombocytopenic purpura-hemolytic uremic syndrome (TTP-HUS) from other complications following allogeneic hematopoietic cell transplantation (HPCT) requires objective, reliable markers. To this purpose, we assessed the clinical usefulness of sequential quantified analysis of fragmented red blood cells (FRC) with the Sysmex XE-2100 automated hematology analyzer. The c...

In the present study, we aimed to compare the clinical outcome of autogeneic and allogeneic natural killer (NK) cells immunotherapy for the treatment of recurrent breast cancer. Between July 2016 and February 2017, 36 patients who met the enrollment criteria were randomly assigned to two groups: autogeneic NK cells immunotherapy group (group I, n=18) and allogeneic NK cells immunotherapy group ...

We compared allogeneic blood usage for two groups of patients undergoing total knee replacement surgery (TKR). Patients were randomized to receive either their post-operative wound drainage as an autotransfusion (n=115) after processing or to have this wound drainage discarded (n=116). Allogeneic blood was transfused in patients of either group whose haemoglobin fell below 9 g dl(-1). Only 7% o...

Multiple myeloma (MM) is a clonal B-cell malignancy that is currently incurable with con‐ ventional chemotherapy, even if high-dose chemotherapy with autologous or allogeneic hematopoietic stem cell transplantation (HSCT) and the development of novel molecular target agents have resulted in a marked improvement in overall survival [1, 2]. Allogeneic HSCT, which induces a clinically significant ...
