Single-dose (270 microg kg(-1)) recombinant activated factor VII for the treatment and prevention of bleeds in haemophilia A patients with inhibitors: experience from seven European haemophilia centres.

Several studies have suggested that recombinant factor VIIa (rFVIIa) is effective and safe at doses >90 microg kg(-1). In March 2007, the European Medicines Agency approved the use of single-dose rFVIIa 270 microg kg(-1) for the treatment of mild-to-moderate bleeds in haemophilia patients with inhibitors. The aim of this study was to describe the use of single-dose rFVIIa in a real-life setting. In November 2007, seven haemophilia specialists from five European countries convened to share and discuss their experiences with the single-dose rFVIIa regimen within haemophilia A. Case histories of eight patients were discussed in this retrospective study. Six adult and two paediatric patients (age range, 19 months-40 years) were treated with single-dose rFVIIa for a variety of target-joint bleeding, other bleeds and bleeding prevention. Treatment was successful in all the eight cases, with most patients requiring one dose to achieve bleeding resolution. No thrombotic or other safety concerns were raised by single-dose rFVIIa treatment. All patients and physicians preferred single-dose rFVIIa treatment to multiple injections; key benefits of single-dose rFVIIa treatment reported by patients and physicians included improved quality of life, greater convenience and ease of administration, improved compliance, faster control of bleeding, less injection-related pain and faster pain relief. In the patients reported here, single-dose rFVIIa 270 microg kg(-1) appears to be an effective and safe haemostatic treatment that improves the quality of life and convenience of treatment for patients. Such treatment might be of particular benefit for patients with difficult venous access or needle phobia.

[Risk factors for thromboembolic disease in young women-the role of hormones]. / Facteurs de risque de maladie veineuse thromboembolique chez les jeunes femmes en contexte hormonal: Risque de survenue d'une maladie thromboembolique veineuse chez les membres de la famille au 1er degré de femmes ayant une maladie veineuse thromboembolique en contexte hormonal : étude « FIT ­ H ¼.

Hormonal exposure in young women increases the risk of venous thromboembolic disease (VTE). Thrombophilia testing is often proposed in women of childbearing age before the initiation of contraception. However, the presence of a familial history of VTE has the potential to be more accurate than the presence of inherited thrombophilia. OBJECTIVE: To demonstrate an association between the risk of VTE in young women with hormonal exposure (pregnancy or oral contraceptive use) and the presence of a previous episode of VTE in their first-degree relatives, according to whether or not a detectable inherited thrombophilia was present. METHODS: We will perform a multicenter case-control cross-sectional study. The main risk factor is defined by the presence of a symptomatic VTE in young women with hormonal exposure. The principle variable is the presence of an objectively diagnosed episode of VTE in first-degree relatives. We will need to include 2,200 family members in 440 cases. EXPECTED RESULTS: We expect to improve understanding of the thrombotic risk in first-degree relatives of patients in hormonal context with or without a past history of VTE.

Antipsychotic drugs and the risk of recurrent venous thromboembolism: A prospective cohort study.

BACKGROUND: Numerous studies have suggested that antipsychotic drugs are associated with an increased risk for a first episode of venous thromboembolism (VTE). However, after anticoagulation discontinuation, the impact of antipsychotic drugs on the risk of recurrent VTE (rVTE) remains unknown. OBJECTIVE: To estimate the risk of rVTE in association with antipsychotic drugs. METHODS: Between May 2000 and December 2012, we included all consecutive patients with a first unprovoked symptomatic VTE and who discontinued anticoagulation. During follow-up, exposure to antipsychotic drugs was systematically assessed. RESULTS: A total of 736 patients with a first unprovoked symptomatic VTE were followed-up during a median period of 27.0 months (interquartile range (IQR) 6.2-60.0). Patients' median age was 66.0 years (IQR 49.0-76.0), 404 (54.9%) were men, and 61 (8.3%) were exposed to antipsychotics during follow-up. The incidence rate of r VTE was 12.1% person-year (95% CI 7.2-20.5) in antipsychotics users compared with 8.3% person-year (95% CI 7.1-9.8) in non-users (p = 0.20). Multivariate analysis showed a significant increased risk of recurrence associated with antipsychotic exposure (adjusted hazard ratio 1.9, 95% CI 1.1-3.3). CONCLUSIONS: In this cohort study, exposure to antipsychotic drugs was found to be associated with an increased risk of rVTE among patients with a previous first unprovoked symptomatic VTE and who discontinued anticoagulation. Larger studies are needed to confirm and further explore this association.

[Pre-eclampsia prevention in 2018 in general population and in lupic women: At the dawn of a personalized medicine?] / Prévention de la pré-éclampsie en 2018 en population générale et chez la femme lupique : à l'aube d'une médecine personnalisée ?

Pre-eclampsia prevention represents a major public health issue, as this vasculo-placental disorder generates a great burden of foeto-maternal morbi-mortality. Aspirin has proved its efficacy in primary and secondary pre-eclampsia prevention, especially when it is given at 150mg per day bedtime before 15 weeks of gestation to high-risk women. In the English trial ASPRE, high-risk women were identified by an algorithm taking into account angiogenic biomarkers ascertained at the end of first trimester of pregnancy. This article focuses on physiopathological mechanisms and risk factors of pre-eclampsia and on the interest of early angiogenic biomarkers dosing during pregnancy, for the assessment of pre-eclampsia risk. Unlike Great Britain or Israel, cost-effectiveness of this algorithm in general population has not been assessed in France. Finally, systemic lupus erythematous is at high risk of vasculo-placental disorders. Although few studies of angiogenic biomarkers dosing during lupus pregnancies identified a correlation between high sFlt1 levels at the end of first trimester and subsequent onset of severe vasculo-placental disorders, with a very good negative predictive value of sFtl1. Angiogenic biomarkers ascertainment for screening of vasculo-placental disorders in pregnant women with systemic lupus erythematous could allow targeting at best women needing an aspirin treatment and a closer monitoring.
