Inherited and acquired thrombophilia are associated with recurrent pregnancy loss (RPL). We have evaluated the efficacy and safety of the low molecular weight heparin enoxaparin in 50 women, (mean age 26 +/- 3 years) with RPL (> or =3 losses in 1st, > or =2 losses in 2nd and > or =1 loss in 3rd trimester) who were found to harbor thrombophilia. Twenty-seven had a solitary thrombophilic defect, ...
Thrombophilia that is common among Caucasians is caused by genetic polymorphisms of coagulation factor V Leiden (R506Q) and prothrombin G20210A. Unlike that in Caucasians, thrombophilia that is common in the Japanese and Chinese involve dysfunction of the activated protein C (APC) anticoagulant system caused by abnormal protein S and protein C molecules. Approximately 50% of Japanese and Chines...
In recent years, our knowledge of the genetic mechanisms of thrombophilia has advanced considerably. The elucidation of the protein C system with the identification of protein C and protein S deficiencies and activated protein C (APC) resistance due to a factor V gene mutation (FV Leiden) as major risk factors of thrombosis has been instrumental for the rapid progress.1–3 Despite these achievem...
Thrombophilia is defined as a condition predisposing to the development of venous thromboembolism (VTE) on the basis of a hypercoagulable state. Over the past decades, great advances in the pathogenesis of VTE have been made and nowadays it is well established that a thrombophilic state may be associated with acquired and/or inherited factors. The rare loss-of-function mutations of the genes en...
Hypercoagulable state or thrombophilia are disorders of the hemostatic mechanisms that increases the risk of thrombosis, both arterial and venous [1]. Inherited thrombophilia is a well-recognized risk factor for venous thrombosis, but its association with arterial thrombosis has not been clearly established. There are also various acquired conditions that are associated with hypercoagulable sta...
Mortality and inherited thrombophilia: results from the European Prospective Cohort on Thrombophilia
BACKGROUND Stratification for risk of recurrence after a first episode of venous thromboembolism (VTE) would affect the duration of anticoagulant therapy. We aimed to determine the incidence of recurrence of VTE in relation to clinical risk factors and standard laboratory testing for heritable thrombophilic defects. METHODS We established a database to prospectively follow-up a cohort of unse...
BACKGROUND The role of thrombophilia and thyroid autoimmunity in unexplained infertility (UI), implantation failure (IF) and recurrent spontaneous abortion (RSA) is controversial and poorly understood. METHODS From March, 2004 to January, 2007, 119 women were prospectively included: 32 oocyte donors, 31 patients with UI, 26 with IF and 30 with RSA. The IF and RSA groups presented normal preim...
BACKGROUND We investigated whether hereditary thrombophilia is more prevalent in women with recurrent IVF-embryo transfer failures. METHODS This case-control study was conducted in an academic tertiary care hospital and compared 45 women with a history of four or more failed IVF cycles (group A) with 44 apparently healthy women matched for age and ethnic origin (group B). All participants wer...
Acquired and inherited thrombophilic factors increase the risk for (recurrent) venous thrombotic disease. However, little is known about the pathophysiological mechanisms causing these recurrences, or the persistence of thrombosis despite adequate treatment. Because residual thrombosis has been associated with a worse prognostic outcome, we performed an explorative study in order to investigate...
