There are only a few reports of total hip replacement in patients with hemophilia A and inhibitors. We performed total hip replacement in an 18-year-old adolescent boy who had high inhibitor titers since infancy. Recombinant factor VIIa (NovoSeven) was used as a bypass agent during the surgery. There was no excessive introperative bleeding; however, postsurgical bleeding occurred and was controlled by sequential administration of recombinant factor VIIa and activated prothrombin complex concentrate (FEIBA)...

To evaluate the diagnosis value of antibodies to phosphatidylserine/prothrombin complex (aPS/PT) in patients with antiphospholipid syndrome (APS) and to determine the clinical features of APS patients with avidity of aPS/PT. Serum samples were collected from 108 APS patients. Sixty patients with pregnancy morbidity, 37 patients with thrombosis without a history of autoimmune diseases, and 89 healthy blood donors were included as the control group. The enzyme-linked immunosorbent assay (ELISA) test was performed to detect the concentration of aPS/PT, including IgG/M, IgG, and IgM forms, in the same serum sample...

We have characterised the pathogenic basis of dysprothrombinaemia in a patient exhibiting paradoxical bleeding and thrombotic defects during pregnancy and postpartum. Genetic analysis revealed that the proband is homozygous for the prothrombin Arg382His mutation, possessing only ~1 % clotting activity. The proband experienced severe bleeding episodes during her pregnancy, which required treatment with prothrombin complex concentrates, and then pulmonary embolism and deep-vein thrombosis at 28 days postpartum, which required treatment with LMWH and fresh frozen plasma...

Insufficiency fractures are a common cause of morbidity among geriatric patients worldwide. Improved outcomes are known to result from decreased delay to definitive operative fixation and mobilization. Use of warfarin is an important potential cause of delay. The ideal mode of warfarin reversal is currently unknown. Prothrombin complex concentrates (PCCs) offer rapid correction with small infusion volume, both of which are important for elderly patients with multiple comorbidities. The authors present 2 cases of insufficiency fractures occurring in geriatric patients receiving warfarin therapy reversed with a 3-factor PCC...

BACKGROUND: Ex situ normothermic machine perfusion (NMP) can be performed after traditional static cold preservation to assess graft function and viability prior to transplantation. It is unknown whether this results in activation of coagulation and fibrinolysis, as may occur upon graft reperfusion in vivo. METHODS: Twelve donor livers declined for transplantation underwent 6 hours of end-ischemic NMP using a heparinized plasma-based perfusion fluid. Concentration of prothrombin fragment F1+2 (marker of coagulation activation), D-dimer, PAP complex, tPA and PAI-1 (markers for fibrinolysis) and alanine aminotransferase (ALT; marker of ischemia/reperfusion [I/R] injury) were measured in perfusion fluid at regular intervals...

Perioperative bleeding remains a major complication during and after surgery, resulting in increased morbidity and mortality. The principal causes of non-vascular sources of haemostatic perioperative bleeding are a preexisting undetected bleeding disorder, the nature of the operation itself, or acquired coagulation abnormalities secondary to haemorrhage, haemodilution, or haemostatic factor consumption. In the bleeding patient, standard therapeutic approaches include allogeneic blood product administration, concomitant pharmacologic agents, and increasing application of purified and recombinant haemostatic factors...

A new anticoagulant agent was prepared by introducing sulfate groups into corn stover xylan through homogeneous reactions. Three organic solvents, N, N-dimethylformamide (DMF), dimethyl sulfoxide (DMSO) and formamide (FA), were adopted as reaction media, with the assistance of LiCl. Structural characterization by FT-IR and (13)CNMR showed that xylan sulfate (XS) could be successfully synthesized with SO3∙Pyridine (SO3∙Py) complexes sulfation reagent in the three media. The effect of sulfation temperature, sulfation time, media type and molar ratio of -SO3/-OH on the degree of substitution (DS) and degree of the polymerization (DP) were studied...

There is an increasing prevalence of cardiovascular diseases that warrant antithrombotic therapy. Antithrombotic therapy includes antiplatelet agents and anticoagulation therapy with vitamin K antagonists (VKAs) or non-Vitamin K oral anticoagulants (NOACs). Antithrombotic therapy is associated with increased rates of bleeding. In this review we summarize the evidence and provide strategies for the management of severe bleeding in the setting of antithrombotic therapy. There is limited data on the management of bleeding in the setting of antiplatelet therapy...

PURPOSE: Our objective is to identify the effect of prothrombin complex concentrate (PCC) in acute intracranial hemorrhage (ICH) by evaluating intraparenchymal hematoma expansion between initial and follow-up head CT at 5-24 h, in those with positive CTA spot sign (CTASS). CTASS is an independent predictor of hematoma growth (1). Acute ICH, regardless of etiology, can present with quick mental status decline often resulting in irreversible brain damage. Hematoma expansion appears to be a modifiable predictor of clinical outcome and an appropriate target for medical therapy...

The immune response to infused factor concentrates remains a major source of morbidity and mortality in the treatment of patients with hemophilia A and B. This review focuses on current treatment options and novel therapies currently in clinical trials. After a brief review of immune tolerance regimens, the focus of the discussion is on preventing bleeding in patients with hemophilia and inhibitors. Recombinant factor VIIa and activated prothrombin complex concentrates are the mainstays in treating bleeds in patients with inhibitors...

PURPOSE OF REVIEW: An increasing number of patients are receiving oral anticoagulants. Since non-vitamin K antagonist oral anticoagulants (NOACs) were approved, primary prevention of ischemic stroke has become simpler. However, managing ischemic stroke and intracerebral hemorrhage while on oral anticoagulation (OAC) has become more complex. This review covers the latest developments in managing ischemic and hemorrhagic stroke in patients receiving vitamin K antagonists (VKA) and NOACs...

INTRODUCTION: Factor XIII (FXIII) cross-links fibrin, completing blood coagulation. Congenital FXIII deficiency is managed with plasma-derived FXIII (pdFXIII) or recombinant FXIII (rFXIII) concentrates. AIM: As the mechanisms protecting patients with low FXIII levels (<5IU/dL) from spontaneous bleeds remain unknown we assessed the interplay between thrombin generation (TG), fibrin formation and clot kinetics before and after FXIII administration in three patients with FXIII deficiency...

PURPOSE: The available clinical data on target-specific oral anticoagulant (TSOAC) reversal agents that are currently in development or have been approved by the Food and Drug Administration (FDA) are reviewed. SUMMARY: The development of TSOACs such as dabigatran, rivaroxaban, edoxaban, and apixaban has presented benefits and new challenges. One of the main challenges associated with the use of TSOACs is the lack of suitable agent-specific reversal agents. Several treatment options for the management of life-threatening bleeding events associated with TSOAC use, such as fresh frozen plasma, prothrombin complex concentrates, and recombinant coagulation factor VIIa, have been used, with inconsistent results...

To report the impact of an inpatient anticoagulation stewardship program at a community hospital to promote optimal anticoagulant use. The anticoagulation team (ACT) stewardship program consists of two clinical pharmacists and hematologists to provide oversight of anticoagulants, high cost reversal agents including prothrombin complex concentrate (PCC, Kcentra™), and heparin-induced thrombocytopenia (HIT) management. Intervention data and number of charts reviewed were collected. Average cost avoidance data was applied to ACT interventions to estimate cost savings...

Compared to conventional therapy, several studies with prothrombin complex concentrate (PCC) have recently demonstrated its superior efficacy in rapidly replacing vitamin K-dependent factors for patients with life-threatening hemorrhage. We present a novel use of PCC in a patient with intracranial hypotension, who had received warfarin for treatment of cortical vein thrombosis. However, after anticoagulation, she proceeded to develop bilateral subdural hematomas with descent of cerebellar tonsils. Given the possibility of an occult dural puncture during labor analgesia, an epidural blood patch was performed after administration of PCC and normalization of coagulation parameters, with prompt improvement of the patient's headache...
