1. 1. Venous thromboembolism. Aspects on risk factors, diagnostic tools and treatment with thrombin inhibition

   Författare :Karin Wåhlander; Göteborgs universitet; []
   Nyckelord :deep vein thrombosis; pulmonary embolism; venous thromboembolism; Factor V Leiden; prothrombin gene G20210A; thrombin inhibition; ximelagatran; melagatran; PT; APTT; D-dimer.;

   Sammanfattning : Venous thromboembolism (VTE), comprising deep vein thrombosis (DVT) and pulmonary embolism (PE), is a multifactorial disease. The aims of the present thesis were to investigate Factor V Leiden and prothrombin G20210A mutations as potential risk factors for VTE during and after major surgery, to compare different D-dimer assays and evaluate their usefulness in the diagnosis of DVT, to investigate clinical effects, safety and pharmacokinetic properties of an oral thrombin inhibitor (ximelagatran) when treating VTE and finally to investigate the usefulness of coagulation assays (APTT and PT) during treatment with thrombin inhibition.

3. 2. Coagulation disturbances in the critically ill patient with special reference to prediction of outcome

   Författare :Gunnar Nilsson; Anestesiologi och intensivvård; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine human and vertebrates ; protein C; mortality; intensive care; health economics; global haemostatic tests; blood coagulation disorders; APC-PCI complex; abdominal aortic aneurysm operation; antithrombin; Medicin människa och djur ;

   Sammanfattning : Critically ill patients in intensive care units (ICU) often have coagulation disturbances. Clinical manifestations such as thromboembolism and/or bleeding may result from activation and consumption of coagulation factors and inhibitors. Disseminated intravascular coagulation (DIC) is a severe condition with an often-poor prognosis. LÄS MER

4. 3. Aspects of platelet transfusions and the association between routine coagulation tests and outcome

   Författare :Sigurdur Benediktsson; Anestesiologi och intensivvård; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Patients with chemotherapy-induced bone marrow aplasia often develop severe thrombocytopenia which requires platelet transfusion. However, up to 25% of the patients show a less than adequate response to the transfusion. LÄS MER

5. 4. Direct Thrombin Inhibitors in Treatment and Prevention of Venous Thromboembolism: Dose – Concentration – Response Relationships

   Författare :Marie Cullberg; Mats O. Karlsson; Ulf G. Eriksson; Nick H.G. Holford; Uppsala universitet; []
   Nyckelord :Pharmaceutical biosciences; Ximelagatran; pharmacokinetic; pharmacodynamic; activated partial thromboplastin time; utility function; dosing strategy; venous thromboembolism; NONMEM; Farmaceutisk biovetenskap;

   Sammanfattning : For prevention and treatment of thrombotic diseases with an anticoagulant drug it is important that an adequate dose is given to avoid occurrence or recurrence of thrombosis, without increasing the risk of bleeding and other adverse events to unacceptable levels. The aim of this thesis was to develop mathematical models that describe the dose-concentration (pharmacokinetic) and concentration-response (pharmacodynamic) relationships of direct thrombin inhibitors, in order to estimate optimal dosages for treatment and long-term secondary prevention of venous thromboembolism (VTE).

7. 5. The effect of thrombin inhibitors on coagulation activity and generation of activated protein C

   Författare :Rikard Linder; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The direct thrombin inhibitor inogatran was, in the TRIM trial (n=1209), compared with unfractionated heparin (UFH) concerning the effect on cardiovascular end-points in unstable coronary artery disease. The results in TRIM demonstrated a trend towards a benefit for UFH during the treatment phase, which was reduced after drug withdrawal. LÄS MER
