Gynaecological management of women with inherited bleeding disorders. A UK Haemophilia Centres Doctors' Organisation Guideline.

Women with inherited bleeding disorders (IBDs) may present to healthcare professionals in a variety of ways and commonly will be encountered by either haematology or gynaecology services. Heavy menstrual bleeding is very often the first manifestation of an IBD. There is a wide variation in severity of bleeding for women with IBD and diagnosis and subsequent management of their condition requires multidisciplinary specialised care which is tailored to the individual and includes excellent cross-specialty communication between gynaecology and haematology teams.

Postpartum bleeding in women with inherited bleeding disorders: a matched cohort study.

: Women with inherited bleeding disorders (IBDs) are reported to have higher rates of primary and secondary postpartum haemorrhage (PPH), even with optimal haemostatic management. We evaluated whether women with IBD have higher odds of PPH compared with those without, when controlled for mode of delivery with a control group of women without IBDs. The obstetric experiences and outcomes of all women with IBD delivering at a tertiary centre between 2008 and 2017, were compared with matched controls (1 : 1).

Multiple myeloma and acquired von Willebrand disease: a combined cause of preanalytical interference causing gel formation?

We report a patient with acquired von Willebrand disease, associated with multiple myeloma. At one stage in his illness, we were unable to analyse a sample sent in a serum separator tube, due to the presence of a gel within the separated serum layer. We suggest this was due to anomalous position of the gel because of the density of the sample caused by its high total protein concentration, exacerbated by fibrin strand formation because of inhibition of appropriate fibrin clot formation secondary to clotting disorder.

Diagnostic accuracy study of a factor VIII ELISA for detection of factor VIII antibodies in congenital and acquired haemophilia A.

Antibody formation to factor VIII (FVIII) remains the greatest clinical and diagnostic challenge to the haemophilia-treating physician. Current guidance for testing for inhibitory FVIII antibodies (inhibitors) recommends the functional Nijmegen-Bethesda assay (NBA). A FVIII ELISA offers a complementary, immunological approach for FVIII antibody testing.

Associations of haemostatic variables with body mass index: a community-based study.

Obesity is a risk factor for venous and arterial thrombosis. We examined relationships between body mass index (BMI) and a number of haemostatic and inflammatory variables in a community-based study of 150 adults (73 male, 77 female; age range, 23-80 years). Associations with BMI were sought after adjustment for age, smoking and diurnal variation.

Inherited thrombophilias and anticoagulation in pregnancy.

Thromboprophylaxis, primary or secondary, should be considered in selected pregnant women with inherited thrombophilias; such women may be divided into high-, medium- and low-risk categories on the basis of the specific thrombophilic defect and any personal or family history of venous thromboembolism (VTE). Women at high risk of VTE should receive treatment doses of low-molecular-weight heparin (LMWH) throughout pregnancy and should remain on anticoagulation for 6 weeks postpartum, or, where appropriate, long-term. Women at moderate risk should be treated with prophylactic fixed-dose LMWH throughout pregnancy and for 6 weeks postpartum.
