The effects of antithrombotic drugs on random and free flap survival have been investigated in the past, but the experimental and clinical results are not in agreement. A perforator-based critical ischaemia model was used to evaluate the effects of different perioperatively administered pharmaceutical agents on tissue ischaemia and to assess the potential additional haemorheological or vasodilative effects of antithrombotics on flap microcirculation. Combined laser Doppler flowmetry and remission spectroscopy revealed an increase in certain microcirculation parameters in most groups in comparison with saline controls, and these changes correlated with flap survival...

Thrombosis is a common complication in cancer patients. Although the major inherited risk factors for thrombophilia are different between Asians and Caucasians, the main acquired risk factors that are associated with the development of venous thromboembolism (VTE) in Asians appear to be similar to those for Caucasians. Malignancy is the most important acquired risk factor for VTE in Asians. Recent studies have shown that the incidence of VTE is significant in Asian patients with cancer, particularly those in an advanced stage...

Venous thromboembolism (VTE), which constitutes pulmonary embolism and deep vein thrombosis, is a common disorder associated with significant morbidity and mortality. Landmark trials have shown that direct oral anticoagulants (DOACs) are as effective as conventional anticoagulation with vitamin K antagonists (VKA) in prevention of VTE recurrence and associated with less bleeding. This has paved the way for the recently published guidelines to change their recommendations in favor of DOACs in acute and long-term treatment of VTE in patients without cancer...

In this study, the anticoagulant, hemorrhagic and antithrombotic effects of glycosaminoglycans from Apostichopus japonicus (AHG) and its depolymerized products (DAHGs) were firstly investigated and compared with that of low molecular weight heparin. AHG and DAHGs exhibited significant prolongation of APTT in vitro. In vivo antithrombus assays of AHG and DAHGs on mice further concluded that AHG and DAHGs could prevent the venous thrombus formation and platelet aggregation effectively. Moreover, AHG and DAHGs could markedly prevent the ex vivo and in vivo thrombus formation at their effective dosage on rats...

PURPOSE OF REVIEW: The traumatically injured patient is at high risk for developing venous thromboembolism. Clinical practice guidelines developed by the American College of Chest Physicians and the Eastern Association for the Surgery of Trauma recognize the importance of initiating thromboprophylaxis, but the guidelines lack specific recommendations regarding the timing and dose of pharmacologic thromboprophylaxis. We review the literature regarding initiation of thromboprophylaxis in different injuries, the use of inferior vena cava filters, laboratory monitoring, dosing regimens, and the use of antiplatelet therapy...

Anticoagulants are a well known cause of drug-induced liver injury (DILI). We recently encountered a 45-year-old male who developed DILI during treatment with enoxaparin, a low-molecular-weight heparin (LMWH), for dural venous thrombosis. The man received enoxaparin 80 mg subcutaneously, twice daily. After 4 days, the patient was asymptomatic but he developed liver aminotransferase elevations: AST 340 U/L and ALT 579 U/L. Investigation revealed an R ratio of 19.9 by day 5 and a Roussel Uclaf Causality Assessment Method score of 10, giving a high probable likelihood that enoxaparin was the cause of hepatic injury...

Drug fever caused by dalteparin-sodium (DS), a low-molecular-weight derivative of heparin, is neither listed in the official drug information and nor published as a case report until today. A preterm infant, born at 26 weeks of gestation, developed fever 2 days after starting a treatment with DS for an intracardial thrombus. The fever reverses soon after changing the treatment to unfractionated heparin and reappeared after reintroduction of DS. Once again, after discontinuing DS, the infant regained normothermia...

Oral vitamin K antagonists (VKA) such as warfarin have been the mainstay of therapy for stroke prevention in patients with non valvular atrial fibrillation (NVAF) while low-molecular-weight heparin, fondaparinux and adjusted-dose warfarin or aspirin have been routinely used for thromboembolism (VTE) prophylaxis in patients undergoing total hip or knee replacement. However, VKAs are associated with considerable limitations, including increased risk of bleeding and narrow therapeutic window. Novel oral anticoagulants (NOACs, now referred as Non Vit K dependent oral anticoagulants), including the direct thrombin inhibitor dabigatran and direct Factor Xa inhibitors such as rivaroxaban and apixaban are now approved alternatives to warfarin for prophylaxis of stroke and systemic embolic events (SEE) in patients with NVAF and treatment and prophylaxis of VTE...

BACKGROUND: Low-molecular-weight heparin and vitamin K antagonists such as warfarin are the gold standard for prohylaxis and treatment of venous thromboembolic disease (VTED). Direct oral anticoagulants (DOACs) result in predictable anticoagulation with significantly reduced inter- and intra-patient variability. DOAC absorption is rapid, with a short half-life and relatively few drug interactions. DOACs are effective and safe at fixed doses without activity monitoring. However, specific situations may require assessment of accurate drug activity...

BACKGROUND: The effect of heparin in improving cancer survival has gained increasing attention over the past decades. Several clinical trials have evaluated the role of heparin on survival outcome and its safety profile in lung cancer patients. Thus, we performed a systematic review and meta-analysis from the results of randomized controlled trials (RCTs) to assess the efficacy and safety of heparin in patients with lung cancer without indication for anticoagulants. METHODS: We searched PubMed, Embase, and The Cochrane Central Register of Controlled Trials databases for relevant studies...

BACKGROUND: Placenta-mediated pregnancy complications include pre-eclampsia, late pregnancy loss, placental abruption, and birth of a small-for-gestational-age (SGA) neonate. These complications are leading causes of maternal, fetal, and neonatal morbidity and mortality in high-income countries. Affected women are at high risk of recurrence in subsequent pregnancies; however, effective strategies to prevent recurrence are absent. Findings from our previous study-level meta-analysis suggested that low-molecular-weight heparin reduced the risk of recurrent placenta-mediated pregnancy complications...

BACKGROUND: Venous thromboembolism (VTE) is a leading cause of death in obese patients undergoing bariatric surgery (BS), but there is neither consensus nor high-level guidelines yet on VTE prophylaxis in this specific population. OBJECTIVE: We aimed to evaluate patterns of BS perioperative thromboprophylaxis practices. SETTING: French obesity specialized care centers (CSO), which are tertiary care referral hospitals for the most severe cases of obesity METHODS: A detailed questionnaire survey (11 opened, 15 closed questions) investigating their prophylactic schemes of anticoagulation (molecule, dose, weight-adjustment, duration, associated measures, follow-up) was sent to the 37 CSO...

Symmetrical peripheral gangrene (SPG) is a rare clinical entity, infective, and noninfective both types of etiologies are responsible. The basic underlying pathology in SPG is being disseminated intravascular coagulation and carries a high mortality. Here, we describe a 52-year-old male with dengue fever, who developed bilateral symmetrical dry gangrene of both hand and feet. His dengue IgM antibody was positive. All the peripheral pulses of the affected limbs were palpable. Color Doppler study of upper and lower limb vessels showed normal flow...

Low molecular weight heparins (LMWH) prepared by partial depolymerization of unfractionated heparin are used globally to treat coagulation disorders on an outpatient basis. Patent protection for several LMWH has expired and abbreviated new drug applications have been approved by the Food and Drug Administration. As a result, reverse engineering of LMWH for biosimilar LMWH has become an active global endeavor. Traditionally, the molecular weight distributions of LMWH preparations have been determined using size exclusion chromatography (SEC) with optical detection...

Thromboprophylaxis for venous thromboembolism is widely used in critically ill patients. However, only limited evidence exists regarding the efficacy and safety of the various thromboprophylaxis techniques, especially mechanical thromboprophylaxis. Therefore, we performed meta-analysis of randomized controlled trials (RCTs) that compared the overall incidence of deep vein thrombosis (DVT) for between unfractionated heparin (UFH), low-molecular-weight heparin (LMWH), and intermittent pneumatic compression (IPC) in critically ill patients...

The prothrombotic state of pregnancy increases the risk of thromboembolic complications and death in women with mechanical heart valves (MHVs). Although it is accepted that these women must be on therapeutic anticoagulation throughout pregnancy, competing maternal and fetal risks, as well as the lack of high-quality data from prospective studies, make the choice of the optimal method of anticoagulation challenging. Vitamin K antagonists (VKAs) are associated with fewer maternal complications, but conversely also the lowest live birth rates as well as warfarin-related embryopathy and fetopathy...

BACKGROUND: Elevated plasma levels of heparin-binding protein (HBP) are associated with risk of organ dysfunction and mortality in sepsis, but little is known about causality and mechanisms of action of HBP. The objective of the present study was to test the hypothesis that HBP is a key mediator of the increased endothelial permeability observed in sepsis and to test potential treatments that inhibit HBP-induced increases in permeability. METHODS: Association between HBP at admission with clinical signs of increased permeability was investigated in 341 patients with septic shock...

Intracranial hemorrhage (ICH) in cancer patients can result from tumor bleeding and from antitumor and anticoagulation therapy. The effect of anticoagulation on the incidence of ICH in cancer patients has not been quantified. Our objective was to determine the risk of intracranial hemorrhage associated with anticoagulation therapy for cancer-associated venous thromboembolism (VTE). Systematic review and meta-analysis of studies assessing the safety of anticoagulation therapy in patients with cancer-associated VTE...
