Summary The optimal management of menorrhagia among women with abnormal laboratory haemostasis is uncertain. In a crossover study, 116 women with menorrhagia [pictorial blood assessment chart (PBAC) score >100], negative gynaecological evaluation and abnormal laboratory haemostasis were randomly assigned to either intranasal desmopressin (IN‐DDAVP) or tranexamic acid (TA) therapy for two menstrual cycles. The subjects then crossed over to the second study drug for two additional cycles. Menstrual blood loss (MBL) was measured by PBAC scores at baseline and after each menstrual cycle. Quality of life (QOL) was assessed with four validated instruments. There was a statistically significant decrease in PBAC scores for both treatments. On average, the estimated decrease in the PBAC from baseline was −64·1 [95% confidence interval (CI) = −88·0, −40·3] for IN‐DDAVP and −105·7 (95% CI = −130·5, −81·0) for TA. The decrease in PBAC score was greater for TA than IN‐DDAVP (a difference of 41·6, P‐value = 0·0002, 95% CI = 19·6, 63·6). The test for treatment‐type effect was significant (P < 0·0001) suggesting a greater reduction in PBAC score with TA. Use of both IN‐DDAVP and TA improved QOL by all four instruments. We conclude that both medications reduced MBL and improved QOL among females with menorrhagia and abnormal laboratory haemostasis, but TA proved more effective.

Introduction Haemophilia has been associated with low bone mineral density (BMD). However, prior clinical studies of this population have neither clearly elucidated risk factors for development of low BMD nor identified who may warrant screening for osteoporosis. Aim To evaluate the relationship between BMD and hemophilic arthropathy and other demographic and clinical variables. Methods We undertook a cross-section study of BMD in adult men with haemophilia. Measures of predictor variables were collected by radiographic studies, physical examination, patient questionnaires, and review of medical records. Results Among 88 enrolled subjects, the median age was 41 years (IQR: 20); median femoral neck BMD (n=87) was 0.90 g/cm2 (IQR 0.24); and median radiographic joint score was 7.5 (IQR 18). Among subjects <50 years (n=62), after controlling for BMI, alcohol, HIV, and White race, BMD decreased as radiographic joint score increased (est.β=−0.006 mg/cm2; 95%CI −0.009, −0.003; partial R2=0.23). Among subjects ≥ 50 years (n=26), 38% had osteoporosis (T score ≤−2.5) and there was no association between BMD and arthropathy. Conclusion Risk factors for low BMD in men with haemophilia < 50 years include hemophilic arthropathy, low or normal BMI, and HIV. Men with haemophilia over age 50 years should have routine screening for detection of osteoporosis.

Physical activity and functional ability are important determinants of quality of life and these metrics are affected by both haemophilia and ageing. Outside haemophilic arthropathy, risk factors leading to reduced physical activity and function in people with haemophilia (PWH) are under-explored. The purpose of this analysis was to determine risk factors for reduced physical activity and functional limitations in PWH. A secondary analysis was conducted on data indexing physical activity and functioning of 88 PWH using data originally collected as part of a cross-sectional study at a single large haemophilia treatment centre. The Framingham Physical Activities Index (PAI), the Hemophilia Activities List (HAL) and the Timed Up-and-Go Test (TUG) were the outcome measures. The World Federation of Haemophilia (WFH) orthopaedic joint score was used as a measure of arthropathy. Multiple linear regression analysis was used to assess the relationship between the outcome measures and covariates. Worsening WFH joint score was independently associated with all three outcome measures (P < 0.05). Increasing age was associated with reduced PAI and increased TUG time (P < 0.05). The HAL summary score was decreased in patients with chronic liver disease (P = 0.006). The adjusted R(2) for each model was ≤ 0.35. This study provides evidence for the relationship between arthropathy and reduced physical functioning/activity, but also highlights that much of the variation in physical functioning/activity is not explained by haemophilia-related characteristics.

While an estimated 13% of women with unexplained menorrhagia have von Willebrand disease (VWD), the frequency of other potential bleeding disorders has been uncertain. This study describes the relatively wide range of laboratory characteristics of women with unexplained menorrhagia and presents issues affecting diagnosis in this population. Women with pictorial blood assessment chart (PBAC) score > 100 were identified at six U.S. sites and asked to remain drug free for 10 days prior to testing. Blood was collected on one of the first four menstrual cycle days and tested at a central laboratory for procoagulant factors, VWD and fibrinolytic factors. Platelet function testing by PFA-100® (PFA) and platelet aggregation with ATP release (PAGG/ATPR) were performed locally using standardized methods. Among 232 subjects, a laboratory abnormality was found in 170 (73.3%), including 124 of 182 White (68.1%) and 34 of 37 Black (91.9%) subjects; 6.0% had VWD, 56.0% had abnormal PAGG/ATPR, 4.7% had a non-VWD coagulation defect (NVCD) and 6.5% had an abnormal PFA only. AGG/ATPR was reduced in 58.9% of subjects, with multiple agonists in 28.6%, a single agonist in 6.1% and ristocetin alone in 24.2%. Frequencies of PAGG/ATPR defects varied by study site and race; frequencies of VWD and NVCD were similar. Laboratory abnormalities of haemostasis, especially platelet function defects, were common among women with unexplained menorrhagia across multiple U.S. sites. To what degree these abnormalities are clinically significant requires further study.

Women at risk of developing a negative long-term memory of the BE can be identified at the time of early postpartum, when the overall birth experience and the perceived intranatal relationship are taken into account.
