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...
The authors describe a new material termed mineralized plasmatic matrix (MPM), a combination of platelets, fibrin concentrate, and autogenous bone to repair alveolar cleft defects. Autogenous cancellous bone is widely used to this end because such bone affords the functionalities (osteogenesis, osteoinduction, and osteoconduction) required for successful outcomes. To optimize these features, au...
Methods. A blood products transfusion algorithm was developed using retrospective data from 42 elective patients (Group A). Two units of platelet concentrate were transfused after cardiopulmonary bypass, followed by 4 u of FFP if bleeding persisted, if platelet count was 100 10 ml when removing the aortic clamp, and vice versa if platelet count was .100 10 ml. The trigger for each therapy step ...
Prothrombin complex concentrates (PCC), licensed for the treatment of hemophilia B, are known to carry a significant risk of thromboembolic complications. Although the reasons for thrombogenicity are not completely understood, several manufacturers have developed purified factor IX concentrates that contain negligible amounts of the other vitamin K-dependent factors. To evaluate whether or not ...
Thrombocytopenic patients refractory to platelet concentrates (PC) could be treated during bleeding episodes with the recombinant activated FVII (rFVIIa). However, monitoring of administration of the rFVIIa or a response to platelet substitution therapy in thrombocytopenia patients is not well documented so far. Using of whole blood ROTEG analysis we monitored the changes in haemostatic paramet...
Background: The short life time of human platelet units has led to a chronic shortage of fresh platelets in blood transfusion centers. Many approaches have been investigated experimentally to produce new hemostatically active platelet products that are capable of long term storage. Infusible platelet membrane (IPM) prepared from fresh or outdated human platelets have been developed as an altern...
