BACKGROUND: The incidence of venous thromboembolism has increased in patients following cancer surgery despite the increased use of prophylactic anticoagulants, suggesting standard doses may be inadequate. We sought to determine the adequacy of enoxaparin prophylaxis in patients undergoing abdominal cancer surgery. METHODS: Peak and trough anti-Xa levels were measured in patients receiving enoxaparin thromboprophylaxis (40 mg daily or 30 mg twice daily, at the surgeon's discretion) after undergoing open abdominal cancer surgery at a single institution...

Apixaban is effective and safe for preventing stroke, and its usage has increased exponentially in recent years. However, data concerning the therapeutic range of apixaban is limited. This study determined the trough and peak levels of apixaban-specific anti-factor Xa activity (AFXaA) in acute ischemic stroke patients with non-valvular atrial fibrillation (NVAF) in Korea. The study included 85 patients who received apixaban. Blood samples were taken to measure the trough and peak levels of AFXaA using a chromogenic anti-factor assay, as well as prothrombin time (PT) and activated partial thromboplastin time (aPTT)...

One of the key benefits of the direct oral anticoagulants (DOACs) is that they do not require routine laboratory monitoring. Nevertheless, assessment of DOAC exposure and anticoagulant effects may become useful in various clinical scenarios. The four approved DOACs - apixaban, dabigatran etexilate, edoxaban and rivaroxaban - have different characteristics impacting assay selection and the interpretation of results. This article provides an updated overview on 1) which test to use (and their advantages and limitations), 2) when to assay DOAC levels, 3) how to interpret the results relating to bleeding risk, emergency situations and perioperative management, and 4) what is the impact of DOACs on routine and specialised coagulation assays...

BACKGROUND: No previous studies have established the optimal antifactor Xa (anti-Xa) level to guide thromboprophylaxis (TPX) dosing with enoxaparin in trauma patients. We hypothesize that achieving 0.2-0.4 IU/mL anti-Xa will decrease venous thromboembolism (VTE) rates after trauma. METHODS: This was a retrospective review of 194 intensive care unit patients sustaining blunt or penetrating trauma from January 2015 to March 2017. All received initial enoxaparin (30 mg BID subcutaneous) and mechanical devices for TPX...

AIMS: Type 2 diabetes (T2D) is connected with several abnormalities in haemostasis; and with higher risk of stroke and systemic embolism in patients with non-valvular atrial fibrillation (NV-AF). However, it is recently unknown whether T2D affects the activity of direct oral anticoagulants (DOACs). The aim of this study was to determine the impact of T2D on DOACs activity in patients with NV-AF. METHODS: This pilot prospective study enrolled totally 65 patients with NV-AF (20 dabigatran-treated, 110 mg/twice daily; 28 rivaroxaban-treated, 15 mg/daily; 17 apixaban-treated, 5 mg/twice daily)...

Pregnancy and postpartum are very high-risk periods for venous thromboembolism events (TEE), which seems to extend far beyond the classical 6-8 weeks after childbirth. Pulmonary embolism (PE) is one of the 3 main causes of direct maternal death in western countries. Between 2010 an 2012 in France, 24 deaths were related to PE giving a maternal mortality ratio of 1/100,000, which is not different from the former report (2007-2009). PE is responsible of 9% of maternal deaths, in equal position with postpartum hemorrhage and amniotic fluid embolism...

Primary hemostasis begins with endothelial injury. VWF, produced by endothelial cells, binds to platelets and links them to subendothelial collagen. Platelet-derived ADP and thromboxane activate non-adhered platelets via their GPIIb/IIIa receptors, allowing these platelets to participate in platelet aggregation. Secondary hemostasis is initiated with the binding of factor VII to extravascular tissue factor (TF). Factors II, VII, IX and X are vitamin K-dependent factors. The role of vitamin K is to assist in the addition of gamma carboxylate groups to glutamic acids in the "GLA" domains of these factors...

: In patients with inherited bleeding disorders undergoing surgery, we recommend assessment of individual risk for venous thromboembolism, taking into account the nature of the surgery and anaesthetic, type and severity of bleeding disorder, age, BMI, history of thrombosis, the presence of malignancy and other high-risk comorbidities. Venous thromboembolism risk should be balanced against the increased bleeding risk associated with anticoagulant use in patients with known bleeding disorders (Grade 1C). In these patients undergoing major surgery, we recommend against routine postoperative use of pharmacological thromboprophylaxis, especially for patients with haemophilia A and B (Grade 1B)...

: A systematic literature search was performed and patients were selected as obese patients undergoing bariatric surgery or obese patients undergoing nonbariatric surgical procedures. In addition, patients were stratified according to low risk of venous thromboembolism and high risk of venous thromboembolism (age >55 years, BMI >55 kg m, history of venous thromboembolism, venous disease, sleep apnoea, hypercoagulability or pulmonary hypertension). Prophylaxis of venous thromboembolism was analysed depending on the type of modality: compression devices of the lower extremities (including intermittent pneumatic compression and graduated compression stockings), pharmacological prophylaxis or inferior vena cava filters...

: Venous thromboembolism is a common and potentially life-threatening complication that occurs in 4 to 15% of patients admitted to ICUs despite the routine use of pharmacological prophylaxis. We therefore recommend an institution-wide protocol for the prevention of venous thromboembolism (Grade 1B). The routine use of ultrasonographic screening for deep vein thrombosis is not recommended when thromboprophylactic measures are in place (Grade 1B), as the detection of asymptomatic deep vein thrombosis may prompt therapeutic anticoagulation that may increase bleeding risk but has no proven reduction of clinically significant thrombotic events...

Current guidelines recommend low-molecular-weight heparin treatment in patients with cancer with established venous thromboembolism (VTE). The aim of this article was to study the pharmacological properties and effectiveness of tinzaparin in patients with cancer as well as its potential anticancer properties. A search of PubMed and ScienceDirect databases up to March 2016 was carried out to identify published studies that detect the properties and use of tinzaparin in oncology. Protamine sulfate partially (60% to 65%) neutralized tinzaparin's anti-Xa activity...

BACKGROUND: Thromboembolic and hypercoagulable diseases are common life-threatening but treatable problems in hospital practice. Fortunately, anticoagulation is an efficacious management practice indicated for arterial, venous, and intracardiac thromboembolism. Clinicians in developing countries may have gaps in their knowledge of anticoagulation therapy/prophylaxis which could affect their clinical decision. OBJECTIVES: The study examined the knowledge and attitude of clinicians to anticoagulation therapy/prophylaxis in some tertiary hospitals in Nigeria...

BACKGROUND: There is no established method for monitoring the anticoagulant effects of apixaban and rivaroxaban. Linear correlation between serum levels and anti-Xa activity has been shown, with r2 ranging from 0.88 to 0.99. However, there are minimal data in patients receiving apixaban 5 mg twice daily or rivaroxaban 20 mg once daily. OBJECTIVE: To evaluate the anti-Xa activity and serum levels at those doses and compare the trough anti-Xa activity. METHODS: This was a single-center prospective study,approved by the institutional review board...
