The Fontan procedure has transformed the lives of children born with single-ventricle physiology, previously deemed inoperable. Worldwide, there are an increasing number of children with Fontan circulation, with the potential for survival into adulthood. Due to the abnormal circulation, Fontan patients have an increased risk of thromboembolic (TE) events, with up to 25% of events leading to death. Despite the importance of preventing TE events in this patient population, there is currently no clinical consensus on the optimal monitoring, thromboprophylaxis therapies, and treatment of these events...

Fibrinolysis is a complex process that controls both hemostasis and thrombosis. The regulation of the fibrinolytic system is mediated through a wide array of cofactors and inhibitors that maintain the hemostatic balance in a delicate equilibrium. As a consequence, disturbances in the fibrinolysis pathway are associated with various disease states, ranging from thrombotic to hemorrhagic clinical phenotypes. In particular, a number of inherited and acquired disorders are associated with an enhanced fibrinolysis leading to a bleeding tendency that in some cases may be life-threatening...

INTRODUCTION: The procoagulant activity of extracellular vesicles (EV) exposing tissue factor (TF) is a promising biomarker for venous thromboembolism (VTE) in cancer patients. We evaluated an in-house EV-TF activity assay (the fibrin generation test) for the prediction of cancer-associated VTE. We also compared the results with the fibrin generation tests to an EV-TF-dependent factor Xa generation assay in samples from pancreatic cancer patients. MATERIALS AND METHODS: Data collected in a multinational, prospective cohort study were used...

INTRODUCTION: The standard for treatment and secondary prevention of venous thromboembolism (VTE) has been vitamin K antagonist (VKA), which might be associated with a higher risk of bleeding particularly in Asian patients. Direct oral anticoagulants (DOAC) have been shown to be safer alternatives for VTE. It remains unclear whether this is the case in Asian ethnicity. MATERIALS AND METHODS: We performed a meta-analysis of randomized controlled trials to evaluate the efficacy and safety of DOACs in Asian and non-Asian patients with acute VTE...

Platelet activation plays an important role in the development of sepsis. During sepsis, platelet activation leads to endothelial cell injury and promotes neutrophil extracellular trap and microthrombus formation, exacerbating septic coagulation and inflammatory reactions. The resultant induction or aggravation of disseminated intravascular coagulation (DIC) leads to organ damage. Antiplatelet drugs can inhibit coagulation and inflammatory reactions in models of sepsis, reducing damage to organ function. Clinical studies suggest that aspirin may improve the prognosis of patients with sepsis...

Cirrhosis is a disease which may develop as a consequence of various conditions. In advanced liver disease, blood coagulation can be seriously affected. Portal hypertension, vascular abnormalities and/or a dysbalance in coagulation factors may result in bleeding disorders or in the development of thrombosis. Fibrinogen is the main protein involved in clot formation and wound healing. The aim of this work was to analyse the glycosylation pattern of the isolated fibrinogen molecules by lectin-based protein microarray, together with the carbonylation pattern of the individual fibrinogen chains, possible changes in the molecular secondary and tertiary structure and reactivity with the insulin-like growth factor-binding protein 1 (IGFBP-1) in patients with cirrhosis...

MicroRNAs (miRNAs) are small endogenous RNAs that post-transcriptionally regulate gene expression. In the last few years, these molecules have been implicated in the regulation of haemostasis, and an increasing number of studies have investigated their relationship with the development of thrombosis. In this review, we discuss the latest developments regarding the role of miRNAs in the regulation of platelet function and secondary haemostasis. We also discuss the genetic and environmental factors that regulate miRNAs...

INTRODUCTION: We sought to determine the test characteristics of an automated INNOVANCE D-dimer assay for the exclusion of pulmonary embolism (PE) and deep venous thrombosis (DVT) in emergency department (ED) patients using standard and age-adjusted cut-offs. METHODS: Cross-sectional, international, multicenter study of consecutive patients with suspected DVT or PE in 24 centers (18 USA, 6 Europe). Evaluated patients had low or intermediate Wells PE or DVT scores...

BACKGROUND: The methodology of thromboprophylaxis post minimally invasive esophagectomy (MIE) is unclear. Thus, we compared the efficacy and safety of fondaparinux and nadroparin on the prophylaxis of venous thromboembolism (VTE) after MIE. MATERIALS AND METHODS: We conducted a randomized, double-blind, treatment-controlled study. Consecutive patients undergoing MIE randomly received a single dose of either nadroparin 2850 AxaIU (Group H) or fondaparinux 2.5 mg (Group F) daily...

BACKGROUND: The Bova score has shown usefulness in the identification of intermediate-high risk patients with acute pulmonary embolism (PE), but lacks prospective validation. The aim of this study was to prospectively validate the Bova score in different settings from the original derivation cohort. METHODS: Consecutive, normotensive patients with acute PE recruited at 13 academic or general hospitals were stratified, using their baseline data, into the three Bova risk stages (I-III)...

INTRODUCTION: Circulating fibroblast activation protein (cFAP) cleaves alpha-2-antiplasmin (α2AP) N-terminally, converting native Met-α2AP into Asn-α2AP. Previous studies in purified model systems showed that Asn-α2AP is faster incorporated into a fibrin clot by activated factor XIII than Met-α2AP, making the fibrin clot more resistant to fibrinolysis. The objective was to investigate whether cFAP level in plasma associated with the amount of α2AP incorporation into fibrin in a new plasma-based clotting assay...

BACKGROUND: Despite the availability of clinical practice guidelines (CPGs), the risk of death or thromboembolic complication associated with heparin-induced thrombocytopenia (HIT) remains high. Our aim was to systematically review the quality of CPGs for HIT and summarize the recommendations. METHODS: CPGs for HIT were systematically searched on PubMed, Embase, guidelines' websites, and Google up to August 6, 2017. Independently, three appraisers assessed the quality of CPGs using the Appraisal of Guidelines for Research & Evaluation II (AGREE II) instrument and extracted the data...

INTRODUCTION: It has been reported that brain tumor resection by craniotomy is a high risk for deep venous thrombosis (DVT), though few data is available in Japanese patients. The aim of this retrospective study was to evaluate the incidence and risk factors for DVT in Japanese adult patients with brain tumor surgery. MATERIALS AND METHODS: Medical records of Japanese adult patients with craniotomy for brain tumor were reviewed. In addition to clinical variables including patients' age, sex, body mass index, previous history of DVT, leg paresis, medications, tumor histology, surgical factors, adjuvant therapy, infection, and duration of post-operative immobilization and hospitalization, plasma D-dimer levels were measured at pre-surgery (baseline), on post-operative day (POD) one to 30 and during adjuvant therapy, and were compared between patients with and without DVT...

INTRODUCTION: It remains unclear whether high plasma glucose levels are associated with venous thromboembolism (VTE). This study investigated the association between fasting plasma glucose (FPG), oral glucose tolerance test (two-hour post-load plasma glucose (2HPG)), diabetes, and VTE. MATERIALS AND METHODS: The population-based, prospective Venous thromboEmbolism In Northern Sweden (VEINS) cohort study included 108,025 residents of Västerbotten County in northern Sweden...

OBJECTIVE: Determination of lupus anticoagulants (LA) is an important, but still challenging test in the diagnosis of antiphospholipid syndrome (APS). This is especially the case in patients using one of the direct oral anticoagulants (DOACs). The aim of our study was to examine the influence of these drugs on DRVVT assays from two companies (in each case: screening test, confirming test and calculated ratio) and on aPTT and lupus-sensitive aPTT. METHODS: We used plasma samples from healthy volunteers spiked with the DOACs dabigatran, rivaroxaban and apixaban (0, 10, 30, 50, 100 ng/mL) for testing...
