Platelet antigens and antibodies in multitransfused patients
Abstract Background and Objectives Following incompatible blood transfusions, anti-HLA and anti- HPA antibodies may develop and cause various disorders such as post-transfusion purpura, platelet refractoriness, and thrombocytopenia leading to bleeding. The aim of this study was to investigate platelet antigens and antibodies in multi-transfused patients. Materials and Methods In this desc...
متن کاملNormal platelet function in platelet concentrates requires non-platelet cells: a comparative in vitro evaluation of leucocyte-rich (type 1a) and leucocyte-poor (type 3b) platelet concentrates
BACKGROUND Therapeutic success of platelet-rich plasma (PRP) may vary based on the composition and preparation method. The objective of this study was to evaluate the cellular components of platelet concentrates produced by a leucocyte-rich (LR-PRP) and a leucocyte-poor PRP systems (LP-PRP). METHODS Parameters evaluated included platelet recovery, platelet concentration, red blood cell (RBC) ...
متن کاملPlatelet-rich fibrin (PRF): a second-generation platelet concentrate. Part III: leucocyte activation: a new feature for platelet concentrates?
Platelet-rich fibrin (PRF) belongs to a new generation of platelet concentrates, with simplified processing and without biochemical blood handling. In this third article, we investigate the immune features of this biomaterial. During PRF processing, leucocytes could also secrete cytokines in reaction to the hemostatic and inflammatory phenomena artificially induced in the centrifuged tube. We t...
متن کاملEvaluation of platelet antigens and antibodies in patients with platelet refractoriness
Abstract Background and Objectives Immune platelet refractoriness is a complication of blood transfusion in patients with multiple platelet transfusions. Antibodies against surface antigens, including human platelet antigens (HPAs) and human leukocyte antigens (HLAs), can be produced which can cause the degradation of transfused platelets by macrophages. In this study, the frequency of platele...
متن کاملPlatelet PAR1 receptor density--correlation to platelet activation response and changes in exposure after platelet activation.
INTRODUCTION A polymorphism (-14 A/T) affecting PAR1 expression on the platelet surface has recently been identified. A two-fold variation in receptor density, which correlated with the platelet response to PAR1-activating peptide (PAR1-AP), has been reported. MATERIALS AND METHODS We used flow cytometry to measure the correlation between the number of PAR1 receptors and platelet activation. ...
