Birth Control Pill vs Birth Control Patch Study

Venous Thrombosis

This study was a randomized, investigator-blinded, cross-over, clinic trial using twenty-four healthy women aged 18-35. All women received two months of the birth control patch or birth control pill, two months without any drug, then two months of the alternative drug. The birth control patch contained 0.75 milligrams ethinyl estradiol and 6 milligrams norelgestromin. The birth control pill contained 35 micrograms ethinyl estradiol and 250 micrograms norgestimate. Blood samples were taken before and after each treatment and were analyzed for the following lab values: D-dimer, von Willebrand factor, factor VIII, total and free protein S, antithrombin, fibrinogen, C-reactive protein and normalized activated protein C sensitivity ratio (nAPCsr). Two thrombin generation-based assays were used: the α2macroglobulin-thrombin endpoint method (α2M-IIa) and calibrated automated thrombinography (CAT).

Prolongation of the Interval Between Monitoring of Warfarin in Stable Patients

Atrial FibrillationHeart Valve Diseases1 more

Patients with mechanical heart valve prosthesis or with irregular beat (atrial fibrillation) have a high risk of blood clot formation. Such clots can result in a stroke. The patients are treated with warfarin - a "blood thinner" - to prevent these complications. The treatment has to be monitored with a blood test called Prothrombin time (PT) every 1-4 weeks. The dose of warfarin has to be changed whenever the PT result is outside of the treatment range. If the result is too low there is an increased risk of blood clots. If, instead, the result is too high there is a risk of bleeding. One third of the patients have very stable PT results and hardly ever have to change the dose. The investigators hypothesis is that these patients can go less often, e.g. every 12 weeks, for the blood tests.

A Pharmacogenetic Study of Warfarin Dosing, "The COUMA-GEN Study"

Atrial FibrillationDeep Vein Thrombosis1 more

Anticoagulation with warfarin is a common and potentially hazardous therapeutic intervention. It is a leading cause of iatrogenic bleeding events and, hence, of malpractice claims. There are no good alternatives presently for warfarin anticoagulation, and even when alternatives become available (i.e., ximelagatran), cost, labeling, and experience (outcomes-related) issues will continue to favor an extensive and ongoing use of warfarin. If the present study is able to confirm an advantage for a genotype-driven algorithm, in terms of improved efficiency, therapeutic efficacy, and, especially, safety, then a pharmacogenetics approach to warfarin dosing can be recommended as the basis for an Intermountain Health Care (IHC)-wide quality improvement initiative that should improve patient outcomes, reduce resource use (costs of achieving safe and therapeutic anticoagulation), and reduce adverse clinical events. COUMA-GEN is a prospective, randomized study of patients who are to begin chronic warfarin therapy for specific, qualifying clinical reasons (i.e., atrial fibrillation (AF), deep vein thrombosis (DVT), or post-orthopedic surgery prophylaxis). Qualifying patients will be consented and randomized to an individualized, genotype-based warfarin-dosing regimen or to standard care (without knowledge of genotype). In each study arm, a predicted maintenance dose will be determined. All patients will receive a baseline International Normalized Ratio (INR). For patients in all 3 entry strata, a starting dose of warfarin that is twice the assigned daily maintenance dose (according to the specific treatment arm) will be prescribed on the first and second days, and then the dose will revert to the assigned maintenance dose.

Safety and Efficacy Trial Evaluating the Use of SR34006 in the Treatment of Deep Vein Thrombosis...

Deep Vein Thrombosis

Patients who have deep vein thrombosis (blood clot in the leg) will be treated in this study. The purpose of the study is to compare the safety and effectiveness of a new injectable anticoagulant (blood thinning) drug administered once each week, SanOrg34006, with the standard way of treating deep vein thrombosis. The standard treatment includes injections or infusions of an anticoagulant drug (Unfractionated Heparin or low molecular weight heparin) for about a week, followed by vitamin K antagonist (VKA) anticoagulant tablets (warfarin or acenocoumarol) which are taken by mouth. Eligible patients will be assigned to treatment with either SanOrg34006 or the combination of Unfractionated Heparin or low molecular weight heparin plus a VKA (warfarin or acenocoumarol) by random chance. Treatment will be known to both patients and their doctors.

Safety and Efficacy of Thrombolysis in Combination With Endhole Aspiration in the Treatment of Acute...

Acute Deep Vein Thrombosis

The purpose of this study is to demonstrate the safety and efficacy of thrombolysis in combination with endhole aspiration in the treatment of acute deep vein thrombosis (DVT). Secondarily, the study team hope to illuminate the financial implications of single session catheter directed therapy versus a potential 48 hour lysis procedure (Lysis is an approach in which vascular specialists deliver clot-dissolving drugs directly to the site of the clot through a catheter).
