Lim MY, Rodgers GM, Branch DW, Simonsen SE. Targeting a higher plasma VWF level at time of delivery in pregnant individuals with von Willebrand disease: Outcomes at a single-institution cohort study. Haemophilia 2024; 30:470-477. [PMID: 38343098 DOI: 10.1111/hae.14953] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2023] [Revised: 01/21/2024] [Accepted: 01/23/2024] [Indexed: 03/14/2024]
Abstract
INTRODUCTION Guidelines on the management of pregnant individuals with von Willebrand disease (VWD) at the time of delivery recommend that von Willebrand factor (VWF) and factor VIII:C (FVIII:C) levels be ≥50% to prevent postpartum haemorrhage (PPH). Yet, high PPH rates persist despite these levels or with prophylactic factor replacement therapy to achieve these levels. AIMS The current practice at our centre has been to target peak plasma VWF and FVIII:C levels of ≥100 IU/dL at time of delivery. The objective of this study was to describe obstetric outcomes in pregnant individuals with VWD who were managed at our centre. METHODS Demographics and outcomes on pregnant individuals with VWD who delivered between January 2015 and April 2023 were collected. RESULTS Forty-seven singleton deliveries (among 41 individuals) resulting in 46 live births and one foetal death were included. Twenty-one individuals had at least one prior birth by the start date of this study, of which 11 (52.4%) self-reported a history of PPH. Early PPH occurred in 12.8% (6/47) of deliveries. Two individuals required blood transfusion, of which one also had an unplanned hysterectomy and transfer to ICU. There were no thrombotic events reported. CONCLUSION The strategy of targeting higher peak plasma VWF and FVIII:C levels (≥100 IU/dL) at the time of delivery may be effective in reducing the risk of delivery-associated bleeding complications in VWD patients. Yet, the rate of early PPH remains unsatisfactory compared to the non-VWD population.

Abstract
Reproductive tract bleeding is an underappreciated health care problem among adolescent and young adult (AYA) females with inherited bleeding disorders (IBDs) comprising von Willebrand disease, platelet disorders, hemophilia carriership, and rare factor deficiencies. IBDs are prevalent in women of all ages and have been detected in about 50% of women with menorrhagia or heavy menstrual bleeding (HMB) and about 20% of women with postpartum hemorrhage (PPH). The clinical spectrum of gynecologic and obstetric bleeding in AYA with IBDs ranges from HMB, ovulation bleeding, and surgical bleeding to miscarriages and life-threatening PPH. Reproductive tract bleeding adversely affects the quality of life of this patient population, in addition to causing substantial morbidity and mortality. Early diagnosis of IBDs offers the opportunity for timely intervention with hormones, hemostatic agents, and prophylaxis with factor concentrates, thereby improving outcomes. This review summarizes the epidemiology, pathophysiology, clinical manifestations, diagnostic approach, management, and prophylaxis for reproductive tract bleeding in AYA with IBDs. This review provides a multidisciplinary approach to the problem, which is critical to improve the outcomes of this patient population.

Abstract
AbstractInherited bleeding disorders are characterized by a diverse clinical phenotype within and across specific diagnoses. von Willebrand disease (VWD), hemophilia A, and hemophilia B comprise 95 to 97% of inherited bleeding disorders, with the remaining 3 to 5% attributed to rare bleeding disorders, including congenital fibrinogen disorders, factor deficiencies (affecting FII, FV, FV + FVIII, FVII, FX, FXI, and FXIII), and platelet function defects. The pregnancy, birth, and the puerperium may be adversely influenced in the setting of an inherited bleeding disorder depending on its type and clinical phenotype. Obstetric hemostatic challenges may sometimes also unmask the presence of a previously unknown inherited bleeding disorder. This review aims to address the approach to pregnancy and birth in the context of an inherited bleeding disorder and highlights the significance of multidisciplinary input into the care of these women.

Abstract
The challenge of pregnancy can be significant to the point of being life-threatening in a woman with a bleeding disorder. Additionally there can be a risk to the fetus and the neonate. A hemostatic defect can affect the course of the pregnancy, but the impact is most feared around delivery in the immediate and the extended post partum period, requiring rapid identification and prompt referral to a hematologist for assistance in management. Identifying the type of congenital bleeding disorder and knowing its inheritance pattern is crucial during counseling prior to conception and in preparation for delivery. A comprehensive approach by a specialized and experienced team in a tertiary care center with access to adequate laboratory monitoring and therapies can facilitate the process. The multidisciplinary team should include a hematologist, an obstetrician, a pediatric hematologist, an anesthesiologist, and in select cases a clinical geneticist and a maternal fetal medicine specialist. In this review article, we will detail the diagnostic path and management of pregnancy and delivery in women with some inherited bleeding disorders, in particular those affected by hemophilia A (HA), hemophilia B (HB), and von Willebrand disease (VWD).

Abstract
Individuals with inherited bleeding disorders (IBDs) have higher bleeding risk during pregnancy, childbirth, and the postpartum period. Clinical management requires recognition of the IBD as high risk for postpartum hemorrhage and a personalized multidisciplinary approach that includes the patient in decision making. When the fetus is known or at risk to inherit a bleeding disorder, fetal and neonatal bleeding risk also need to be considered. In pregnant IBD patients, it is common for providers to need to make decisions in the absence of high level of certainty evidence. We here present the case of a pregnant von Willebrand disease patient that reached multiple decision points where there is currently clinical ambiguity due to a lack of high level of certainty evidence. For each stage of her care, from diagnosis to the postpartum period, we discuss current literature and describe our approach. This is followed by a brief overview of considerations in other IBDs and pregnancy.

Abstract
OBJECTIVES The present review aims to summarize the state-of-the-art von Willebrand disease (VWD) treatment focusing on specific clinical settings (obstetrics, surgery, long-term prophylaxis and comorbidities) as well as on the use of a Von Willebrand factor (VWF) concentrate with low FVIII content. METHODS Literature research and case reports. RESULTS AND CONCLUSIONS Considering that patients affected by VWD have an intact ability to synthesize FVIII, in order to avoid excessive levels of FVIII, a highly purified plasma VWF concentrate with low FVIII content could be particularly useful in those patients and clinical circumstances at high thrombotic risk as well as for long-term prophylaxis. When deciding the optimal therapeutic strategy, physicians should take into account both the patient's history and the differences among available concentrates according to the clinical situations requiring treatment.

Abstract
BACKGROUND The management of pregnant women with von Willebrand disease (VWD) is complex as physiological pregnancy-induced increases in plasma von Willebrand factor (VWF) may be blunted or absent. Women with VWD experience a heightened risk of postpartum hemorrhage (PPH) and special consideration must be given regarding neuraxial anesthesia (NA) and the need for prophylaxis at time of delivery. These challenges are compounded by a lack of robust evidence to guide clinical decision-making. OBJECTIVES AND METHODS To determine the current international clinical practices in the management of pregnancy for women with VWD, the International Society on Thrombosis and Haemostasis (ISTH) conducted an international survey of health-care providers (HCP). RESULTS One hundred thirty-two respondents from 39 countries were included in the final analysis. Variations in clinical practice were identified in antenatal (monitoring of plasma VWF and ferritin levels), peripartum (optimal plasma VWF target at delivery) and postpartum management (definitions used for PPH and postpartum monitoring). A key area of divergence was suitability for NA for women with type 2 and type 3 VWD, with many respondents advising against the use of NA even with VWF supplementation (29% type 2 VWD, 37% type 3 VWD) but others advising use once plasma VWF activity was >50 IU/dL (57% type 2 VWD; 50% type 3 VWD). CONCLUSIONS This survey highlighted areas of uncertainty surrounding common management issues for pregnant women with VWD. These data underscore the need for international collaborative research efforts focused on peripartum management to improve care for pregnant women with VWD.

Abstract
Pregnancy and childbirth pose an important hemostatic challenge for women with von Willebrand disease (VWD) and can be associated with an increased risk of maternal and neonatal bleeding complications. VWD is a genetically and clinically heterogeneous bleeding disorder caused by a deficiency or an abnormality in the function of von Willebrand factor. Understanding inheritance pattern, hemostatic response to pregnancy, and response to treatment is essential for provision of individualized obstetric care and optimal outcome. A multidisciplinary approach to management with a close liaison between the obstetric team and the hemophilia treatment center is required for continuity of care from preconception counseling through to antenatal, peripartum, and postpartum care. Delivery plan must be coordinated by the multidisciplinary team and include decisions on place and mode of delivery, implementation of safe analgesia/anesthesia, and peripartum hemostasis. In this clinical case-based review, we aim to deliver evidence-based practical guidance for challenges encountered during pregnancy and management of childbirth and puerperium.

Abstract
Women with inherited bleeding disorders, including carriers of hemophilia A and B, or with von Willebrand disease, have an increased risk of bleeding during pregnancy and delivery. The unborn child may also be affected by the bleeding disorder for which specific measures have to be considered. This requires a multidisciplinary approach, with a team that includes a hematologist, a pediatric hematologist, a clinical geneticist, an obstetrician-perinatologist, and an anesthesiologist. An optimal approach includes prepregnancy genetic counseling, prenatal diagnostic procedures, and a treatment plan for delivery for both the mother and child. Recent retrospective studies show that even if strict guidelines are followed, these women are still at risk of postpartum bleeding. This occurs even if coagulation factor levels are normalized, either due to the pregnancy-induced rise of factor levels or by infusion of coagulation factor concentrates at the time of delivery. In this article, we describe our current diagnostic and clinical management of pregnancy and delivery in women with inherited bleeding disorders. We also briefly discuss possible interventions to improve the outcome of current strategies by increasing target factor levels during and after delivery.

Abstract
Currently, there is no consensus on the optimal management to prevent postpartum hemorrhage (PPH) in hemophilia carriers. We aimed to evaluate peripartum management strategies in relation to maternal and neonatal bleeding outcomes by performing an extensive database search up to August 2020. Seventeen case-reports/series and 11 cohort studies were identified of overall 'poor' quality describing 502 deliveries. The PPH incidence in the individual patient data was 63%; 44% for those women receiving prophylaxis to correct coagulation and 77% for those without (OR 0.23, CI 0.09-0.58) and in cohort data 20.3% (26.8% (11/41) vs. 19.4% (55/284) (OR: 1.53, 95% CI: 0.72-3.24), respectively. Peripartum management strategies mostly consisted of clotting factor concentrates, rarely of desmopressin or plasma. Tranexamic acid appears promising in preventing secondary PPH, but was not used consistently. Neonatal bleeding was described in 6 affected male neonates, mostly after instrumental delivery or emergency CS, but insufficient information was provided to reliably investigate neonatal outcome in relation to management. The high PPH risk seems apparent, at most mildly attenuated by prophylactic treatment. Prospective cohort studies are needed to determine the optimal perinatal management in hemophilia.

Abstract
For many women, pregnancy and childbirth represent their first major hemostatic challenges. Despite advancements in obstetric care, up to 2 to 5% of all deliveries are complicated by postpartum hemorrhage (PPH). To mitigate bleeding risk, physiological changes occur in pregnancy, including increases in plasma von Willebrand factor (VWF) and factor VIII levels. For women with von Willebrand disease (VWD), these physiological alterations are blunted or absent. As a result, women with VWD have a heightened risk of PPH, both primary (in the first 24 hours) and secondary (>24 hours to 6 to 12 weeks postpartum). Pregnancy and delivery management for women with VWD should therefore be carefully coordinated as part of a multidisciplinary team approach. In the absence of large-scale clinical trials, the management of women with VWD during pregnancy is guided by expert consensus guidelines. Clinical practices internationally are not uniform, and areas of considerable clinical uncertainty exist. Traditional peripartum plasma VWF thresholds for hemostatic cover and therapeutic targets are currently under scrutiny, as PPH is not eliminated in women with VWD who receive replacement therapy. The benefit and optimal duration of postpartum tranexamic acid have yet to be defined, and standardized methods of quantification of blood loss at the time of delivery are currently lacking. In this article, we review the evidence base to date and explore the current clinical challenges in the management of pregnant women with VWD.

Abstract
The area of women and inherited bleeding disorders has undergone quick expansion in recent years. More patients are being identified and expertise to diagnose and manage these patients is now essential for practising physicians. Programs to help educate and empower patients and caregivers are now in place. Common inherited bleeding disorders affecting women include von Willebrand disease (VWD), inherited platelet disorders, and rare inherited bleeding disorders such as factor VII (FVII) deficiency and factor XI (FXI) deficiency. Specific clinical tools have been developed to help clinicians and patients screen for the presence of these bleeding disorders in both adult and pediatric populations. Affected women can experience heavy menstrual bleeding and resulting iron deficiency anemia, postpartum hemorrhage, and hemorrhagic ovarian cysts which need to be properly managed. Excessive bleeding can adversely affect quality of life in these women. Front line therapy for bleeding in mild cases focuses on the use of non-specific hemostatic agents such as DDAVP ®, tranexamic acid and hormonal agents but specific factor replacement and/or blood products may be required in more severe cases, in severe bleeding or as second line treatment when bleeding is not responsive to first line agents. Iron status should be optimised in these women especially in pregnancy and use of an electronic app can now help clinicians achieve this. These patients should ideally be managed by a multidisciplinary team whenever possible even remotely. Although clinical research has closed some knowledge gaps regarding the diagnosis and management of these women, there remains significant variation in practise and lack of evidence-based guidelines still exists in many spheres of clinical care in which caregivers must rely on expert opinion. Ongoing efforts in education and research will continue to improve care for these women and restore quality of life for them.

Abstract
INTRODUCTION Women with von Willebrand disease (VWD) are at a higher risk of bleeding, which might affect the health of mother and child during pregnancy and the intra- and postpartum periods. This retrospective cohort study evaluates changes in the coagulation parameters von Willebrand factor antigen (VWF:Ag), von Willebrand ristocetin cofactor (VWF:RCo), and Factor VIII activity (FVIII:C) during pregnancy in patients with VWD. In total, 44 pregnancies of 38 patients were assessed (VWD type 1 n = 32, type 2A n = 3, type 2B n = 1, type 2 subtype unidentified n = 2). The patients' median age at childbirth was 32 years (range 22-40). RESULTS A significant increase in coagulation parameters was found in patients with VWD type 1 (VWF:Ag, VWF:RCo, and FVIII:C p = 0.000). In the third trimester, VWF:Ag and FVIII:C normalized in all patients with VWD type 1; in 3 patients VWF:RCo remained below the normal range. Patients with VWD type 2 showed a significant increase of VWF:Ag (p = 0.003) and FVIII:C (p = 0.011), and a non-significant increase of VWF:RCo (p = 0.097). In 4 of 9 pregnancies of patients with VWD type 2, all surveyed coagulation parameters normalized until the third trimester. CONCLUSION For the majority of the observed patients, the von Willebrand parameters increased during pregnancy.

Abstract
SummaryVon Willebrand disease (VWD) is the most common inherited bleeding disorder. Bleeding scores in VWD, focused in particular on mucosal bleeding, can be very useful in the diagnosis and validation of different types of treatment. The results of an extended prospective study with a large amount of information on clinical phenotype and implications in treatment are reviewed in this article. Treatment of mucosal and joint bleeding in severe VWD remains difficult in some patients. Due to the lack of data on the use of prophylaxis in these patients it is difficult to establish optimal treatment regimens. An overview of the literature, with a focus on the ongoing PRO.WILL study, is provided here. Furthermore, understanding the changes in von Willebrand factor (VWF) levels during pregnancy is very important for establishing the optimal management strategy for pregnancy and delivery in women with VWD. A recently published prospective observational cohort study in women with and without VWD during the postpartum period provides important data that should allow the improvement of postpartum treatment protocols.

Abstract
Von Willebrand disease (VWD) is the most common inherited bleeding disorder with an estimated prevalence of ~1% and clinically relevant bleeding symptoms in approximately 1:10,000 individuals. VWD is caused by a deficiency and/or defect of von Willebrand factor (VWF). The most common symptoms are mucocutaneous bleeding, hematomas, and bleeding after trauma or surgery. For decades, treatment to prevent or treat bleeding has consisted of desmopressin in milder cases and of replacement therapy with plasma-derived concentrates containing VWF and Factor VIII (FVIII) in more severe cases. Both are usually combined with supportive therapy, e.g. antifibrinolytic agents, and maximal hemostatic measures. Several developments such as the first recombinant VWF concentrate, which has been recently licensed for VWD, will make a more "personalized" approach to VWD management possible. As research on new treatment strategies for established therapies, such as population pharmacokinetic-guided dosing of clotting factor concentrates, and novel treatment modalities such as aptamers and gene therapy are ongoing, it is likely that the horizon to tailor therapy to the individual patients' needs will be extended, thus, further improving the already high standard of care in VWD in most high-resource countries.

Abstract
INTRODUCTION Women with inherited bleeding disorders are at increased risk for bleeding complications during pregnancy and the postpartum period, particularly postpartum haemorrhage (PPH). AIM This retrospective study evaluates pregnancy management through the Inherited Bleeding Disorders Clinic of Southeastern Ontario, the clinical factors associated with pregnancy-related abnormal bleeding and assesses tranexamic acid use in the postpartum treatment of bleeding disorder patients. METHODS A chart review of 62 pregnancies, from 33 women, evaluated patient characteristics (age, haemostatic factor levels) and delivery conditions (mode of delivery, postpartum treatment) in relation to abnormal postpartum bleeding. RESULTS This cohort revealed increased risk of immediate PPH with increased age at delivery (mean age: 30.1 years with PPH, 26.5 years without PPH, P < 0.013), and birth by vaginal delivery (P < 0.042). Low von Willebrand factor (VWF) antigen or factor VIII (FVIII) in the third trimester was not associated with an increased risk of PPH; however, low VWF:RCo was associated with increased immediate PPH despite treatment with continuous factor infusion (P < 0.042). Women treated with tranexamic acid postpartum had less severe bleeding in the 6-week postpartum (P < 0.049) with no thrombotic complications. CONCLUSIONS This study contributes to the growing body of work aimed at optimizing management of bleeding disorder patients through pregnancy and the postpartum period, showing patients are at a higher risk of PPH as they age. Risk factors such as low third trimester VWF:RCo have been identified. Treatment with tranexamic acid in the postpartum period is associated with a reduced incidence of abnormal postpartum bleeding.

Abstract
PURPOSE OF REVIEW The morbidity and mortality of postpartum hemorrhage (PPH) in women with an underlying bleeding disorder requires vigilance by the hematologist. RECENT FINDINGS Recent studies suggest that women with underlying bleeding disorders may be 'undertreated' at the time of delivery in aiming for too low a target elevation that historically per numerous society guidelines has aimed for VWF/FVIII:C levels to be 'only' greater than 50% when in actuality the levels should be akin to what is achieved in a normal pregnancy. The result appears to be an increase in the rate and degree of PPH. In this context, although recent studies imply DDAVP is well tolerated, DDAVP may not be appropriate because it may not raise the levels into the normal supraphysiological range nor maintain it for several days. Particularly in women with rare bleeding disorders, i.e., non- FVIII C or VWF deficient, adjunctive antifibrinolytic therapy, e.g., tranexamic acid, appears to be in order as a prophylactic measure. SUMMARY Women with an underlying bleeding disorder appear to be at a heightened risk for PPH if the respective coagulation factor level is not appropriately replaced to the level that is physiologically achieved in a normal pregnancy. Furthermore, there appears to be underuse of tranexamic acid for prophylaxis of PPH in this population.

Abstract
The bleeding phenotype of children with von Willebrand disease (VWD) needs to be characterized in detail to facilitate diagnosis during childhood and aid in the planning and assessment of treatment strategies. The objective was to evaluate the occurrence, type, and severity of bleeding in a large cohort of children with moderate and severe VWD. We included 113 children (aged 0-16 years) with Type 1 (n = 60), 2 (n = 44), and 3 (n = 9) VWD with von Willebrand factor (VWF) antigen and/or VWF ristocetin cofactor levels ≤ 30 U/dL from a nation-wide cross-sectional study ("Willebrand in the Netherlands" study). Bleeding severity and frequency were determined using the International Society on Thrombosis and Hemostasis-Bleeding Assessment Tool (ISTH-BAT) with supplementary pediatric-specific bleeding symptoms (umbilical stump bleeding, cephalohematoma, cheek hematoma, conjunctival bleeding, postcircumcision and postvenipuncture bleeding). We found that all 26 postmenarche girls experienced menorrhagia. Other common bleedings were cutaneous (81%), oropharyngeal (64%), prolonged bleeding from minor wounds (58%), and epistaxis (56%). Pediatric-specific bleeding symptoms were present in 44% of patients. ISTH-BAT bleeding score was higher in index cases than in affected family members (median, 12.0 vs. 6.5, P < 0.001), higher in Type 3 VWD than in Type 2 or 1 (17.0 vs. 10.5 or 6.5, P < 0.001) and higher in children with severe (<10 U/dL) than moderate VWD (10-30 U/dL) (11.0 vs. 7.0, P < 0.001). Frequency of any bleeding, epistaxis, and oral cavity was higher in types 2 and 3 than in Type 1 VWD and was associated with VWF levels. We conclude that pediatric-specific bleeding symptoms occurred in a large proportion of children with moderate or severe VWD and should be included when evaluating children for VWD.

Abstract
Abstract
VWD is the most common inherited bleeding disorder known. It is caused by a deficiency or dysfunction of the VWF molecule. Bleeding risk varies between modest increases in bleeding seen only with procedures to major risk of spontaneous hemorrhage depending upon the type of VWD. The treatment approach to VWD has changed little in the past 2 decades, but there are numerous subtleties in optimal management. Management includes the prevention or treatment of bleeding by raising endogenous VWF levels with medications such as desmopressin or providing exogenous VWF concentrates. Fibrinolytic inhibitors and topical hemostatic agents are also effective adjunctive measures. Bleeding specific to women presents a special challenge because of heavy menstrual bleeding and pregnancy. Successful management of pregnancy in patients with VWD involves coordination with obstetrics, anesthesia, and the coagulation laboratory monitoring VWF:RCo and FVIII:C levels. Prophylactic treatment with VWF concentrates is emerging as an effective preventive therapy in patients with severe disease. Antibodies to VWF present a special challenge in the management of rare patients with type 3 disease. New therapies on the horizon include recombinant VWF, anti-VWF aptamers, and medications such as IL-11 to raise VWF levels. The key to effective treatment of VWD is an accurate diagnosis of the specific type and selection of hemostatic products appropriate for the clinical situation.

Abstract
OBJECTIVES To report the management of carriers of haemophilia in a French university hospital and assess different issues of these patients. PATIENTS AND METHODS Retrospective study of the carriers of haemophilia who consulted at the university hospital of Montpellier, France, between 1995 and 2011. Information were obtained from medical records and from a questionnaire sent to carriers. We recorded data about biological characteristics, bleeding tendency and management of pregnancies. RESULTS Sixty-four carriers of haemophilia A or B were included. Their median FVIII or FIX level was 52 % (range, 15-137 %). Menstrual bleeding lasted more than 7 days in 31 % of carriers. A total of 142 pregnancies started in 54 carriers, and 101 resulted in live births with 26 boys with haemophilia. Sixty-two prenatal diagnoses carried out, 15 have terminated their pregnancy because of a hemophiliac male fetus. Seventy-six percent of deliveries were vaginal delivery and 49 % took place in a level-3 maternity. There were 10.8 % and 8.5 % primary and secondary post-partum hemorrhage, respectively. CONCLUSION The risk of bleeding among carriers of haemophilia is associated with their antihemophilic factor level. To improve the management of carriers, a multidisciplinary and standardized medical record, with a specific questionnaire to evaluate bleedings, could be considered. A regional register that lists all carriers, regardless of their antihemophilic factor level, would also be useful.
