Filter by:The purpose of this study is to demonstrate the ability of STA® Liatest® D-Di combined with a clinical pretest probability (PTP) to safely exclude pulmonary embolism (PE) or Deep Venous Thrombosis (DVT) in a 3 month follow-up.
The issue to be studied is the prevalence of venous thromboembolism (VTE) in hospitalized pediatric patients, and to identify if there are subgroups of patients who may be at higher risk. There are two hypotheses that will be looked at in this study. The first hypothesis is that individual risk factors for VTE in hospitalized pediatric patients are: age >14, obesity, black race, female sex, presence of a central venous line (CVL), traumatic mechanism of injury, orthopaedic surgery, and use of oral contraceptives. The second hypothesis is that risk factors have an additive effect such that risk stratification can be developed to identify those patients with the highest risk.
The objective of this study is to investigate whether paracetamol, given at therapeutic doses (2g/day and 3 g/day), may potentiate the anticoagulant effect of warfarin.
This pilot study is designed to determine the feasibility of conducting a randomized clinical trial comparing fondaparinux sodium (Arixtra) once daily with enoxaparin (Lovenox®) twice daily with respect to preventing deep vein thrombosis (DVT) and pulmonary embolism (PE) after bariatric surgery in obese patients.
Thrombosis is a significant medical complication in children with chronic diseases. The currently utilized treatments have many drawbacks which can lead to poor outcomes. More modern therapies are available but have not been systematically tested in children. This study will determine whether one such medication, bivalirudin is a safer and more effective alterative. This study will monitor what effects the drug has upon the child's body and how the body processes the study drug (absorption, metabolism and elimination). The study will also evaluate the drug's effectiveness by following how long it takes to dissolve the clot. The safety issues being monitored relate to any observations of major or minor bleeding episodes after taking the drug, and/or any other side effects.
Cancer is a well known risk factor for venous thromboembolism (VTE) such as deep venous thrombosis (DVT) and pulmonary embolism (PE). Today we know that patients with adenocarcinomas of the gastro intestinal tract (GI-tract) often is in a hypercoagulable state. In our observational study we collect patients admitted to department with a tentative diagnosis of upper GI cancer including pancreas cancer and offer them flow doppler ultrasounds of both legs for diagnosis of DVT in the entire treatment time. The routine CT-scan of the chest is modified to diagnose PE. This will be compared with blood samples analysed for coagulation markers including D-dimer - a fibrinogen degradation product.
The purpose of the study was to evaluate efficacy and safety of the new acute treatment of deep venous thrombosis by use of low-molecular-weight heparin compared with standard treatment using unfractionated heparin, especially concerning long-term morbidity.
We are performing a research study to learn more about the control of an individual's blood thinning (anticoagulation) on warfarin. Individuals from an anticoagulation clinic are being asked to participate in order to see if a lottery which provides the opportunity to win money in combination with the use of the Med-eMonitor might be useful in helping patients to achieve better control of their anticoagulation therapy. Half of the participants will be enrolled in the lottery arm and the other half will be a control group who will receive the Med-eMonitor only.
Several case reports indicate that the use of the antibiotic combination amoxicillin and clavulanic acid (AM-CLAVAC) can interact with warfarin pharmacodynamics. However, fever per se might also be responsible of these warfarin overdose reports, as well as the use of high dose paracetamol. The aim of the present study is to determine if AM-CLAVAC can increase the pharmacodynamics of warfarin among patients at steady state Double blinded cross over controlled study vs placebo performed in 12 evaluable patients treated with warfarin with an INR target 2 to 3 and a stable INR and a stable dose.
A blood clot in the veins, also known as deep venous thrombosis (DVT), is one of the most common complications after surgery. This may result in death if a clot breaks off and travel to the lungs; this is referred to as pulmonary embolism (PE). After heart surgery the incidence of DVT ranges from 20-48% and following lung surgery the incidence is 19-26%. In order to decrease the likelihood of this complication, patients receive by injection a blood thinning medicine. Heparin is the usual medicine used for this purpose following heart and lung surgery. Recently there have been reports that other medicines may be more effective than heparin for this purpose. Also there have been reports that some patients develop antibodies to heparin. When this occurs, this may prevent the heparin from being effective and may even promote the formation of blood clots. Antibodies to heparin may be present more often following heart and lung surgery than other types of surgery. There is a new medicine called desirudin (Iprivask), which may be used instead of heparin to prevent blood clots following heart and lung surgery. Desirudin is currently approved by the FDA to prevent blood clots following hip surgery. The purpose of this study is to compare desirudin with heparin for the prevention of vein clots after heart and lung surgery.
