Heparin and low molecular weight heparins (LMWHs) have been the drug of choice for the treatment or the prevention of thromboembolic disease. Different methods are employed to prepare the LMWHs that are clinically approved for the market currently. In particular, enoxaparin, which has a reducing sugar moiety at the end-site of polysaccharide, is prepared by alkaline depolymerization. Focusing on this end-site-specific activity of LMWHs, we conjugated the tetraoligomer of deoxycholic acid (TetraDOCA; TD) at the end-site of enoxaparin via nonenzymatic glycosylation reaction...

The Department of Health has defined hospital acquired venous thromboembolism (VTE) as any VTE event occurring within 90 days of hospital admission or surgery. (1) Hospital acquired thrombosis (HAT) is common during and after hospital admission and is considered a major patient safety issue. Current NICE guideline (CG 92) 2010, recommends that medical patients assessed at risk of VTE should have pharmacological prophylaxis commenced as soon as possible after risk assessment has been completed and continued until the patient is no longer at increased risk of VTE...

Low molecular weight heparins (LMWHs) are important anticoagulant drugs that are prepared through depolymerization of unfractionated heparin. Based on the types of processing reactions and the structures of the products, LMWHs can be divided into different classifications. Enoxaparin is prepared by benzyl esterification and alkaline depolymerization, while dalteparin and nadroparin are prepared through nitrous acid depolymerization followed by borohydride reduction. Compositional analysis of their basic building blocks is an effective way to provide structural information on heparin and LMWHs...

OBJECTIVES: A prospective evaluation of nonchemotherapy drug-induced agranulocytosis (DIA) cases, which are infrequent in the pediatric population. We characterize agranulocytosis cases and assess lab test differences between drug- and nondrug-induced agranulocytosis. METHODS: Through our Prospective Pharmacovigilance Program from Laboratory Signals at Hospital we detected pediatric agranulocytosis cases from July 2007 to December 2010. This program estimates the incidence, drug causality, clinical features, outcomes of DIA pediatric cases, and assesses laboratory differences with respect to non-DIA...

INTRODUCTION: Wipple disease (WD) is a rare chronic disease caused by the bacillus Tropheryma whipplei. Constitutive, rheumatologic, gastrointestinal, cardiac, cerebral, lymphatic, cutaneous, and ophthalmological signs are possible systemic symptoms. However, thrombotic manifestations are rarely described as "stroke-like syndrome" or arterial thrombosis. Diagnosis is based on clinical manifestations and pathological examination. Laboratory findings may include anemia, leukocytosis, and thrombocytosis...

OBJECTIVE: The critically ill, premature patients of neonatal intensive care units are susceptible to venous thrombosis, an adverse event associated with short- and long-term morbidity. Venous thrombosis is frequently treated with low-molecular-weight heparins (LMWHs) such as enoxaparin, but optimal dosing of LMWH must balance the morbidity of venous thrombosis with the potential adverse affects of anticoagulation. The optimal dosing of enoxaparin for premature infants is unclear. The objective of this study was to describe enoxaparin therapy and follow-up in critically ill neonates diagnosed with venous thrombosis...

AIM: To study the effectiveness of sulodexide for systemic disorders correction in patients with acute pancreatic necrosis. MATERIAL AND METHODS: The study included 60 patients with acute pancreatic necrosis who were divided into main and control groups by 30  patients. Their age varied from 27 to 79. Standard combined therapy with prevention of disseminated intravascular coagulation and thrombotic complications was recommended in all patients. In the control group enoxaparin therapy in prophylactic doses (4,000 IU (40 mg) per day) was used...

Extended-duration pharmacological thromboprophylaxis, for at least 28 days, is effective for the prevention of symptomatic venous thromboembolism (VTE) in high-risk surgical patients but is of uncertain benefit in hospitalized medical patients. We aimed to evaluate the efficacy and safety of extended-duration thromboprophylaxis in hospitalized medical patients. We conducted a systematic PubMed, Medline and EMBASE literature search until June 2016 and a meta-analysis of randomized controlled trials which compared extended-duration with short-duration thromboprophylaxis in hospitalized medical patients...

Importance: The Patient Protection and Affordable Care Act of 2010 brought attention to adverse drug events in national patient safety efforts. Updated, detailed, nationally representative data describing adverse drug events can help focus these efforts. Objective: To describe the characteristics of emergency department (ED) visits for adverse drug events in the United States in 2013-2014 and describe changes in ED visits for adverse drug events since 2005-2006...

BACKGROUND: Low molecular weight heparin is routinely used for thromboprophylaxis in pregnancy and the puerperium. Consensus guidelines recommend waiting 10-12h after administration of a thromboprophylactic dose of low molecular weight heparin before performing a neuraxial block or removing an epidural catheter. Thromboelastography (TEG®) has been reported to be sensitive to the effects of enoxaparin 4h after administration. The purpose of this study was to use TEG to examine coagulation changes in the first 10h after a thromboprophylactic dose of tinzaparin in an attempt to ratify the current consensus guidelines about timing of neuraxial blockade and epidural catheter removal...

BACKGROUND: -Stroke is a morbid and potentially mortal complication among patients hospitalized with acute medical illness. The potential of extended-duration thromboprophylaxis with the factor Xa inhibitor betrixaban to reduce the risk of stroke compared with standard-dose enoxaparin in this population was assessed in this retrospective APEX trial substudy (Acute Medically Ill Venous Thromboembolism Prevention With Extended Duration Betrixaban). METHODS: -Hospitalized acutely medically ill subjects (n=7513) were randomized in a double-dummy double-blind fashion to either extended-duration oral betrixaban (80 mg once daily for 35-42 days) or standard-dose subcutaneous enoxaparin (40 mg once daily for 10±4 days) for venous thromboprophylaxis...

BACKGROUND: Preeclampsia and intrauterine fetal growth restriction (IUGR) are two of the most common causes of maternal and perinatal morbidity and mortality. Current methods of predicting those at most risk of these conditions remain relatively poor, and in clinical practice past obstetric history remains the most commonly used tool. Aspirin and, in women at risk of preeclampsia only, calcium have been demonstrated to have a modest effect on risk reduction. Several observational studies and randomised trials suggest that low molecular weight heparin (LMWH) therapy may confer some benefit...

Factor V (FV) is a pivotal coagulation factor present in plasma and platelets. It plays an essential role in secondary haemostasis acting as a cofactor in the prothrombinase complex, catalysing the conversion of prothrombin to thrombin. There is little evidence on the management of mayor orthopaedic surgery in paediatric or adolescents subjects with this coagulopathy and almost no information about thromboprophylaxis in these situations. We report a case of a hip replacement in a 14-year-old girl with moderate FV deficiency (0...

BACKGROUND: Although Sjögren's syndrome has been known to complicate with white matter lesions, encephalopathy, or stroke, reports of cerebral venous sinus thrombosis due to Sjögren's syndrome with atypical antibodies are rare. CASE REPORT: A 50-year-old woman was admitted to our neurological ward with nausea and vomiting following acute onset of severe headache in the left occipital region. Brain computed tomography revealed no abnormalities. The patient was fully conscious, with normal cognitive functioning, but exhibited unsteady tandem gait...

OBJECTIVE: Thrombin (Thr) generation at the uteroplacental interface induces inflammation and weakens fetal membranes. Tissue factor (TF) is a powerful procoagulant that is increased by Thr in decidual cells (DCs). The TF expression may play an important role in modulating Thr-induced inflammation. The purpose of this study was to assess the effect of heparin, including nonanticoagulant (desulfated) heparins, on basal and Thr-induced expression of TF and inflammatory cytokines in DCs...
