Driving improvement of diagnosis and awareness of heavy menstrual bleeding in women among physicians.

INTRODUCTION: A number of barriers in care exist for women/girls with bleeding disorders. Little progress has been made to overcome them, particularly regarding levels of awareness of healthcare professionals (HCPs) and women/girls. AIM: To evaluate awareness and perception of heavy menstrual bleeding (HMB) and bleeding disorders among HCPs and women/girls. METHODS: A three-part qualitative study was conducted, including HCPs and women/girls from over seven countries. Part 1 included eleven 60-min interviews with experts discussing HMB diagnostic barriers, which were further assessed in surveys among 6099 women/girls, 353 general practitioners (GPs), and 426 obstetricians and gynaecologists (OB/GYNs) during Part 2. Part 3 included three 1.5-2-h workshops with 20 clinicians and patient representatives covering HMB knowledge, criteria defining HMB and HCP resourcing for diagnosis. RESULTS: Many HCPs do not conduct certain investigations for women/girls presenting with HMB, and 22% of GPs lack confidence in the management of HMB. Only 8% of GPs use screening tools to evaluate menstrual blood loss, and 13% of GPs and 15% of OB/GYNs assess underlying bleeding disorders. Seventy-six percent of menstruating women/girls believed they could recognise HMB symptoms 'well'. However, 23% of these women/girls would not seek medical advice for abnormal/prolonged menstruation disrupting their lives. Disruptions were reported in 34% of women/girls from the general population and 61% of women with at-risk symptoms of HMB. CONCLUSION: Many women/girls and HCPs have limited awareness of important HMB indicators. There is a need for standardized clinical criteria to promote efficient diagnoses and management.

A post hoc analysis of previously untreated patients with severe hemophilia A who developed inhibitors in the PUPs A-LONG trial.

ABSTRACT: Inhibitor development is a major therapeutic complication for people with hemophilia. The phase 3 PUPs A-LONG study evaluated the safety and efficacy of efmoroctocog alfa (a recombinant factor VIII Fc fusion protein, herein referred to as rFVIIIFc) in previously untreated patients (PUPs) with severe hemophilia A. Male PUPs <6 years old were enrolled and received rFVIIIFc; inhibitor development was the primary end point. Post hoc analyses, including patient treatment regimen patterns and timing of inhibitor development, descriptive and Kaplan-Meier analyses of time to first inhibitor-positive test by treatment regimen and by titer, and consumption, were performed to describe patients who developed inhibitors during PUPs A-LONG. We investigated patient characteristics (eg, demographics and genotype) and nongenetic risk factors (eg, intense factor exposure and central venous access device [CVAD] placement) that may predict inhibitor development and characteristics of inhibitor development (low-titer vs high-titer inhibitor). Baseline characteristics were similarly distributed for age, race, and ethnicity across both patients who were inhibitor-positive and those who were inhibitor-negative (all P > .05). High-risk F8 variants were associated with development of high-titer inhibitors (P = .028). High-titer inhibitor development was often preceded by the presence of a low-titer inhibitor. Patients whose low-titer inhibitor progressed to a high-titer inhibitor received a higher mean dose per infusion (98.4 IU/kg, n = 5) compared with those whose low-titer inhibitor resolved spontaneously (59.2 IU/kg, n = 7; P = .033) or persisted (45.0 IU/kg, n = 5; P = .047). There was no association between CVAD placement surgery and inhibitor development. Post hoc analyses suggest that F8 genotype and dose of factor are as important as inhibitor risk factors and require further investigation. This study was registered at ClinicalTrials.gov as #NCT02234323.

Clinical and treatment characteristics of infants and toddlers less than 2 years of age with hemophilia.

ABSTRACT: Infants and toddlers (ITs) with hemophilia have unique bleeding features. Factor prophylaxis has been shown to decrease the risk of intracranial hemorrhage (ICH), which supports recommendations to begin at a young age. Clinical and demographic characteristics were analyzed for 883 ITs ≤2 years old with hemophilia A and B, seen at US Hemophilia Treatment Centers and enrolled in the Community Counts Registry, a surveillance program of the Centers for Disease Control and Prevention. ICH in the first 2 years of life was seen in 68 of 883 (7.7%) ITs, of whom 8 of 68 (11.8%) were on continuous prophylaxis at the time of ICH. ITs in this study usually started prophylaxis within the first year of life (mean, 10.3 months), with earlier ages of prophylaxis initiation in later birth cohorts in ITs with hemophilia A. Compared with those without a family history (FH) of hemophilia, known positive FH of hemophilia was associated with earlier age of diagnosis (P ≤ .0001) and decreased rates of vaginal delivery (P = .0006). The use of factor VIII mimetics and extended half-life clotting factor prophylaxis increased with later birth cohorts for ITs with hemophilia A and B. The study highlights that ICH rates in ITs with hemophilia remains substantial and underscores the need for further research to identify modifiable risk factors to prevent ICH by earlier diagnosis and initiating prophylaxis early, even within the first month of life.
