BACKGROUND: Early diagnosis of acute mesenteric ischemia (AMI) based on clinical judgment has been proved to be too difficult. Therefore, it is important for identifying clinical parameters that can differentiate AMI from other acute abdomen upon presentation. METHODS: We analyzed a database of 106 consecutive patients admitted to the emergency ward for suspected AMI in whom diagnosis of AMI was confirmed by laparotomy, CT angiography or mesenteric angiography. The patients' demographics, previous history, clinical signs, results of laboratory investigations and ultrasonography were collected...

Oral oestrogen increases the risk of venous thromboembolism (VTE) and increases production of sex hormone-binding globulin (SHBG) in a dose-dependent manner. SHBG has been suggested to be involved in venous thromboembolism. We examined the effects of oral ultra-low-dose oestradiol on circulating levels of SHBG and coagulation parameters, and we compared the effects to those of transdermal oestradiol. Twenty women received oral oestradiol (500 μg) every day (oral ultra-low-dose group) and 20 women received a transdermal patch (50 μg) as a transdermal group...

Ticks secrete several anti-hemostatic factors in their saliva to suppress the host innate and acquired immune defenses against infestations. Using Ixodes scapularis ticks and age-matched mice purchased from two independent commercial vendors with two different immune backgrounds as a model, we show that ticks fed on immunodeficient animals demonstrate decreased fibrinogenolytic activity in comparison to ticks fed on immunocompetent animals. Reduced levels of D-dimer (fibrin degradation product) were evident in ticks fed on immunodeficient animals in comparison to ticks fed on immunocompetent animals...

Inflammation is known to preclude tolerance after transplantation. We have previously shown that systemic inflammation in xenograft recipients (SIXR) precedes activation of coagulation in the absence of T cell responses. Accordingly, SIXR may amplify innate and adaptive immune responses against xenografts after pig-to-primate xenotransplantation, even with efficient immunosuppressive therapy. We evaluated the impact of anti-inflammatory agents on pro-inflammatory cytokines and chemokines in pig artery patch and heart xenograft recipients...

INTRODUCTION: Pneumatic tube system (PTS) in hospitals is commonly used for the transport of blood samples to clinical laboratories, as it is rapid and cost-effective. The aim was to compare the effects on haematology samples of a newly acquired ~2km-long PTS that links 2 hospitals with usual transport (non-pneumatic tube system, NPTS). METHODS: Complete blood cell count, routine coagulation assays, platelet function tests (PFT) with light-transmission aggregometry and global coagulation assays including ROTEM® and thrombin generation assay (TGA) were performed on blood samples from 30 healthy volunteers and 9 healthy volunteers who agreed to take aspirin prior to blood sampling...

Atrial fibrillation (AF) is well known for being a major risk factor of thromboembolic stroke. We could recently demonstrate an association of monocyte-platelet aggregates (MPAs) with the degree of thrombogenicity in patients with AF. This study investigated platelet activation markers, as potential biomarkers for the presence of left atrial (LA) thrombus in patients with AF. One hundred and eight patients with symptomatic AF underwent transesophageal echocardiography (TEE) before scheduled cardioversion or pulmonary vein isolation...

BACKGROUNDS: Cancer progression has been associated with host hemostasis system. Whether preoperative plasma hemostasis factors can predict survival in colorectal cancer is quite intriguing. METHODS: We conducted a prospective cohort study to validate the prognostic significance of three hemostasis parameters - fibrinogen, fibrin degradation products (FDPs) and D-dimer - in non-metastatic colorectal cancer patients treated with curative resection. RESULTS: All three parameters were positively correlated with C reactive protein (CRP) levels and Glasgow Prognostic scores (GPS)...

Women are at increased risk of venous thromboembolism (VTE) during pregnancy and VTE remains one of the main causes of maternal mortality in developed countries (Konstantinides SV, et al. Eur Heart J 2014; 35(43):3033-69, 69a-69k). Although an accurate diagnosis of acute pulmonary embolism (PE) in pregnant patients is thus of crucial importance, the diagnostic management of suspected PE is challenging for this specific patient category. As D-dimer levels increase physiologically throughout pregnancy, the optimal D-dimer threshold to rule out PE during pregnancy remains unknown...

BACKGROUND: A majority infections caused by dengue virus (DENV) are asymptomatic, but a higher incidence of severe illness, such as dengue hemorrhagic fever, is associated with secondary infections, suggesting that pre-existing immunity plays a central role in dengue pathogenesis. Primary infections are typically associated with a largely serotype-specific antibody response, while secondary infections show a shift to a broadly cross-reactive antibody response. METHODS/PRINCIPAL FINDINGS: We hypothesized that the basis for the shift in serotype-specificity between primary and secondary infections can be found in a change in the antibody fine-specificity...

Omalizumab is very effective in the majority of patients with severe chronic spontaneous urticaria (CSU), but its mechanism of action is still unclear. In CSU the coagulation cascade is activated with an intensity that parallels the disease severity, and elevated plasma D-dimer levels are associated with a poor response to both antihistamines and cyclosporin. We measured D-dimer plasma levels before and after the first administration of omalizumab in 32 patients with severe CSU. A number of clinical and laboratory parameters were recorded, including the urticaria activity score, presence of angioedema, disease duration, C-reactive protein, anti-nuclear, and anti-thyroid antibodies...

BACKGROUND: Current treatments for acute ischemic stroke and venous thromboembolism, such as recombinant tissue plasminogen activator and thrombectomy, are limited by a narrow time window and the risk of bleeding. DS-1040 is a novel low-molecular weight compound inhibiting the activated form of thrombin-activatable fibrinolysis inhibitor (TAFIa), developed as a fibrinolysis enhancer for treatment of thromboembolic diseases. OBJECTIVES: This first-in-human, randomized, placebo-controlled, three-part, phase 1 study was conducted to evaluate the safety, pharmacokinetics (PK), and pharmacodynamics (PD) of DS-1040 in healthy subjects...

Despite a recommended 7-10 days of thromboprophylaxis, medically ill patients remain at increased risk of developing venous thromboembolism (VTE) after hospital discharge. Here, we present a contemporary review on the efficacy and safety of extended-duration thromboprophylaxis with direct oral anticoagulants (DOACs) in hospitalized medically ill patients. A search of publication and trial databases of controlled trials conducted from 2010 to 2016 using the key terms apixaban, rivaroxaban, and betrixaban showed three phase III trials that met our search criteria...
