Obesity in haemophilia patients: effect on bleeding frequency, clotting factor concentrate usage, and haemostatic and fibrinolytic parameters.
The prevalence of obesity in patients with haemophilia (PWH) is increasing. We investigated the effect of obesity on bleeding frequency and clotting factor concentrate (CFC) usage in PWH and assessed whether prothrombotic changes observed in obesity differ between controls and PWH. Number of bleeds and CFC usage were compared between obese (N = 51) and non-obese (N = 46) haemophilia A patients. ⋯ Obesity is associated with an increase in net CFC usage in PWH, but has no effect on bleeding frequency. In addition, obesity attenuates hyperfibrinolysis in PWH. Future research investigating whether obese PWH need CFC treatment dosed on weight or whether a lower dosage would suffice to prevent and treat bleedings is needed.

Clinical TrialEx-vivo response to blood products and haemostatic agents after paediatric cardiac surgery.
Bleeding complications after cardiac surgery are of particular importance in children because they are more prone to volume overload. To optimize haemostatic intervention, the coagulopathy has to be characterized, and knowledge about the effect of blood products and haemostatic agents is needed. The aims of the present study were to investigate changes in coagulation profiles after paediatric cardiac surgery and the effect after ex-vivo addition of blood products and haemostatic agents. ⋯ Finally, addition of fibrinogen concentrate, FFP or tranexamic acid improved clot stability significantly. Whole blood coagulation was significantly impaired after cardiac surgery in children. Ex-vivo studies showed a total reversal of the coagulopathy after addition of pooled platelets and significantly improved clot stability after addition of fibrinogen concentrate, FFP and tranexamic acid, respectively.

Physicians reverse patients' warfarin anticoagulation with frozen plasma or prothrombin complex concentrate. Our objective was to determine adverse event frequency after urgent reversal with frozen plasma versus the prothrombin complex concentrate Octaplex. ⋯ Octaplex for urgent reversal of warfarin resulted in faster reversal and lower red cell transfusion requirement with fewer adverse events than frozen plasma.

Case ReportsSevere pediatric blunt trauma--successful ROTEM-guided hemostatic therapy with fibrinogen concentrate and no administration of fresh frozen plasma or platelets.
Use of allogeneic blood products to treat pediatric trauma may be challenged, particularly in relation to safety. We report successful treatment of a child with severe abdominal and pelvic injuries with preemptive fibrinogen supplementation followed by rotational thromboelastometry (ROTEM)-guided, goal-directed hemostatic therapy. ⋯ Activated partial thromboplastin time was prolonged and Quick values were low but ROTEM clotting time values remained normal, therefore, no thrombin-generating drugs were considered necessary. This case shows the potential for hemostatic treatment with coagulation factor concentrates to be applied to pediatric trauma.
