Introduction: Despite increasing awareness of issues faced by women and girls with inherited BDs (WGBD), standards of care are lacking, with disparities in diagnosis and treatment for WGBD across Europe. We aimed to develop practical principles of care (PoC) to promote standardization of care for WGBD within European Haemophilia Treatment and Comprehensive Care Centres (HTC/CCCs). Methods: The co‐creation process, supported by the European Association for Haemophilia and Allied Disorders, consisted of four multidisciplinary meetings with health care providers (HCPs) experienced in WGBD care, and European Haemophilia Consortium representatives, combined with broad patient and HCP consultations in the European haemophilia community. Relevant medical societies outside Europe were contacted for confirmation. Results: We developed ten PoC for WGBD, stressing the importance and benefits of a centralized, multidisciplinary, comprehensive, family‐centred approach to support and manage WGBD during all life stages. These PoC emphasise the right to equitable access and quality of care for all people with BDs, irrespective of gender. Multiple medical societies outside Europe also confirmed their support for endorsement. Conclusions: Ten PoC for WGBD evolved from an iterative process among stakeholders, supported by relevant medical societies worldwide. These PoC can serve as a benchmark for diagnosis and comprehensive multidisciplinary management of WGBD, and improve awareness of their unique challenges. They offer a framework to guide HTC/CCCs in providing equitable care for all WGBD, both in their own services and in other healthcare settings. Implementation of these principles aims to positively impact the health, wellbeing and quality of life for WGBD. [ABSTRACT FROM AUTHOR]

Summary: The level of venous thrombosis risk in women who experience spontaneous or induced pregnancy loss has previously been uncertain. However, recent data indicate that the risk of venous thrombosis in women undergoing pregnancy termination in the first trimester is increased two‐fold compared to non‐pregnant women but reduced five‐fold compared to women in the 6 weeks following a term birth. The termination procedure itself appears not to influence thrombosis risk. In light of this data, this consensus statement provides recommendations for reducing the risk of venous thrombosis in women undergoing spontaneous or induced pregnancy loss based on Royal College of Obstetricians and Gynaecologists risk stratification guidelines.

Antithrombin deficiency is identified as one of the most potent risk factors for venous thromboembolism during pregnancy. Therapeutic low molecular weight heparin is recommended, but it can be difficult to attain sufficient anticoagulation since low molecular weight heparin requires antithrombin to exert its anticoagulant effect. We carried out a multicentre case-series assessing the dose of low molecular weight heparin required to achieve therapeutic anti-activated factor X levels in pregnant women with antithrombin deficiency. We assessed 27 pregnancies in 18 women with severe antithrombin deficiency, which we defined as an antithrombin level of <0.55 IU/ml (with or without prior venous thromboembolism) or an antithrombin level < 0.8 IU/ml and a personal history of venous thromboembolism. Our data illustrate the need for high doses of low molecular weight heparin to achieve therapeutic anti-activated factor X levels (average 20,220 IU/day). All pregnancies ended in live birth (excluding one elective termination), although intrauterine growth restriction occurred in five (18%). [ABSTRACT FROM AUTHOR]

Recurrent pregnancy loss ( RPL) affects 1% pregnancies and is multi-factorial in origin. The role of the acquired thrombophilia antiphospholipid syndrome ( APS) as a common and potentially treatable cause of RPL is well established but this is less so for inherited thrombophilia. In obstetric APS the combination of aspirin and heparin has improved outcomes. By analogy, the use of low molecular weight heparin ( LMWH) has become commonplace in women with inherited thrombophilia and also those with unexplained miscarriage to help safeguard the pregnancy. This review will examine the pathophysiological role of thrombophilia in pregnancy loss, and the evidence for anticoagulant-based intervention. The limited data supporting the use of heparin for women with RPL and inherited thrombophilia suggests adoption of a more cautious and judicious approach in this setting. [ABSTRACT FROM AUTHOR]
