Pharmacologic prophylaxis of deep vein thrombosis and venous thromboembolism (VTE) is an important aspect of medical care, particularly in the inpatient setting. Low-molecular weight heparins, heparin, and fondaparinux are commonly used agents to prevent VTE, each of which has well established dosing regimens in patients with normal body mass index. Dosing of these medications in morbidly obese populations (BMI > 40 kg/m(2)) is not as clearly defined in guidelines. This article reviews published data to support specific dosing regimens and monitoring strategies of these agents in this population...

Timing and dosing of chemical venous thromboembolism (VTE) prophylaxis in brain injury is controversial. Risk of bleeding while using high dose unfractionated heparin (UFH) in overweight patients to prevent VTE is also unknown. The purpose of this study was to describe the use of subcutaneous heparin 7500 units for VTE prophylaxis in overweight patients. This was a retrospective study comparing patients over 100 kg who received either 7500 units Q8 h (n = 141) (high dose group, HDG), or 5000 units Q8 h (n = 257) (traditional dose group, TDG), of UFH subcutaneously...

INTRODUCTION: Heparin is often prescribed during pregnancy with the intention of improving perinatal outcomes on the basis that it exerts an anticoagulant action in the inter-villous space. Accumulating in-vitro and in-vivo evidence indicates that heparin's beneficial effects in pregnancy may result from 'non-anticoagulant' effects including the promotion of angiogenesis. METHODS: To study the effect of heparin within the placenta, we performed secondary analyses on a pilot trial where 32 women with negative thrombophilia screens and second-trimester evidence of placental insufficiency were randomized to standard care or antenatal self-administration of unfractionated heparin (UFH) 7500 IU twice-daily...

OBJECTIVE: Although controversial, carotid artery stenting (CAS) has been proposed as being safer than carotid endarterectomy (CEA) for patients with a contralateral internal carotid occlusion (CCO). Arguably, with a CCO, CAS should be even safer than CEA if a shunt is not used. Accordingly, we reviewed our experience with 2183 CEAs performed routinely without a shunt to evaluate the risk of CEA performed in a subset of 147 patients with a CCO. METHODS: Between 1988 and 2011, 147 CEAs (111 men [75%], 36 women [25%]) were routinely performed without a shunt despite CCO...

Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic complication of assisted reproduction technology. The syndrome is characterized by cystic enlargement of the ovaries and a fluid shift from the intravascular to the third space due to increased capillary permeability and ovarian neoangiogenesis. Its occurrence is dependent on the administration of human chorionic gonadotrophin (hCG). β-hCG and its analogs, estrogen, estradiol, prolactin, histamine and prostaglandins have all been implicated in OHSS but now it is increasingly better understood that the vasoactivesubstances such as interleukins, tumor necrosis factor-α, endothelin-1, and vascular endothelial growth factor (VEGF) secreted by the ovaries have been implicated in increasing vascular permeability...

BACKGROUND: Thromboprophylaxis is commonly required following caesarean section. However the effect of thromboprophylactic dosages of subcutaneous heparin on coagulation is unknown because conventional laboratory tests are largely unaffected. The aim of this study was to determine if thromboelastography could detect and quantify the effect of unfractionated heparin on coagulation profile when given at the time of surgery. METHODS: Nineteen women undergoing elective caesarean section were recruited...

Bemiparin is a low molecular weight heparin (LMWH) that has been available in Europe for 10 years and is indicated for thromboprophylaxis and the treatment of deep vein thrombosis. Bemiparin is termed a 'second-generation' LMWH, because at 3.6 kDa, it has a lower mean molecular weight than other LMWH and a narrow distribution of saccharide chain lengths, with most being less than 6 kDa. As a result of its low molecular weight, it has low anti-factor IIa (thrombin) activity and an anti-Xa : anti-IIa activity ratio of 8 : 1 compared with a ratio of 1 : 1 for unfractionated heparin...

Human cytomegalovirus (CMV), an agent of infection (CMVI), lethally dangerous for immune deficient neonates and adults was investigated in vitro as a target for a therapeutic effect of new membrane-active polyanionic compounds (MPC). Previous studies on the alicycle- and sulfate-modified carboxy-MPCs revealed a well-defined tendency of the anti-CMV activity amplification in parallel with increasing of the content of sulfate groups, enhancing the negative charge of the macromolecule. The dominating role of the electrostatic factor was confirmed by the highest activity of AS-688, compound with maximum sulfation among the tested MPCs...

Pregnant patients with acute venous thrombosis or a history of thrombosis may need alternative anticoagulation, when heparin intolerance occurs. Only limited data on the use of the heparinoid danaparoid are available in literature. We reviewed the use of danaparoid in 51 pregnancies of 49 patients identified in literature between 1981 and 2004. All patients had developed heparin intolerance (32 due to heparin-induced thrombocytopenia, 19 mainly due to heparin-induced skin rashes) and had a current and/or past history of thromboembolic complications...
