Abstract
BACKGROUND Ultra-rare inherited bleeding disorders (BDs) present important challenges for generating a strong evidence foundation for optimal diagnosis and management. Without disorder-appropriate treatment, affected individuals potentially face life-threatening bleeding, delayed diagnosis, suboptimal management of invasive procedures, psychosocial distress, pain, and decreased quality-of-life. RESEARCH DESIGN AND METHODS The National Hemophilia Foundation (NHF) and the American Thrombosis and Hemostasis Network identified the priorities of people with inherited BDs and their caregivers, through extensive inclusive community consultations, to inform a blueprint for future decades of research. Multidisciplinary expert Working Group (WG) 3 distilled highly feasible transformative ultra-rare inherited BD research opportunities from the community-identified priorities. RESULTS WG3 identified three focus areas with the potential to advance the needs of all people with ultra-rare inherited BDs and scored the feasibility, impact, and risk of priority initiatives, including 13 in systems biology and mechanistic science; 2 in clinical research, data collection, and research infrastructure; and 5 in the regulatory process for novel therapeutics and required data collection. CONCLUSIONS Centralization and expansion of expertise and resources, flexible innovative research and regulatory approaches, and inclusion of all people with ultra-rare inherited BDs and their health care professionals will be essential to capitalize on the opportunities outlined herein.

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
AbstractVon Willebrand disease (VWD) is the most common inherited bleeding disorder, which results from a deficiency or dysfunction of von Willebrand factor (VWF). The major symptoms of patients affected by VWD include mucocutaneous and gastrointestinal bleeding, easy bruising, and prolonged provoked bleeding due to injury or surgery. Although women and men are equally likely to be affected by VWD, women continue to be disproportionately affected by the bleeding challenges. Women with VWD suffer from sex-specific symptoms, such as menorrhagia, and are at higher risk of reproductive problems and recurrent miscarriage. Furthermore, pregnant women with VWD are more likely at higher risk of suffering from primary and secondary peripartal hemorrhage and anemia and the need for transfusions. Despite being affected by gynecologic and obstetrical bleeding, women face multiple barriers in obtaining an accurate diagnosis. This constitutes a problem that needs to be addressed, and early appropriate medical care should be ensured. There are several effective treatment options for women with VWD that can significantly improve their quality of life, including desmopressin, VWF concentrates, hormonal therapy, and antifibrinolytic therapy. During pregnancy, the monitoring of VWF activity levels is essential. The peripartal management depends on the type of VWD and on the measured levels of VWF levels and activity prior to delivery.

Abstract
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. This guideline is intended for both haematologists and gynaecologists who are involved in the diagnosis and management of women with bleeding disorders. It sets out recommendations about how to investigate heavy menstrual bleeding (HMB), the commonest presentation for women with IBD to hospital services, to guide physicians about how to diagnose an IBD and covers the management of women with known IBD and HMB. The second section sets out recommendations for patients known to have IBD and covers management of patients with IBD in the setting of gynaecological surgery and management for all other non-surgical gynaecological situations.

Abstract
INTRODUCTION Frequent and severe bleeding events (SBE) in patients with inherited qualitative platelet disorders Bernard-Soulier Syndrome (BSS) and Glanzmann Thrombasthenia (GT) can lead to secondary iron deficiency anemia (IDA). SBE are primarily treated with platelet transfusions or recombinant activated factor VII (rFVIIa) infusions. The impact of IDA on bleeding management and disease outcomes is understudied. AIM To evaluate bleeding management, outcomes, and any association with IDA in pediatric patients with BSS and GT. METHODS Retrospective chart-review of pediatric patients with BSS or GT followed at a single hemophilia treatment center between 2007 and 2019. RESULTS We identified 14 patients with BSS (n = 2) or GT (n = 12). Patients received rFVIIa (7%), platelet transfusions (7%), or a combination of both (57%) for SBE. Eleven patients (79%) had IDA requiring oral and/or intravenous iron replacement and 50% required red blood cell transfusions. Due to recurrent SBE and refractory IDA, three patients (21%) received rFVIIa prophylaxis at 90 μg/kilogram 2-3 times/week for ≥15 months. Patients initiated on rFVIIa prophylaxis had a median baseline hemoglobin of 9.8 g/dL (min-max: 8.0-10.7 g/dL) compared to 11.7 g/dL (8.4-13.8 g/dL) for patients treated on-demand. Following initiation of rFVIIa prophylaxis, median hemoglobin and ferritin increased by 1.3 g/dL (0.7-2.5 g/dL) and 14.6 ng/mL (0.2-42.9 ng/mL), respectively, and bleeding rates were reduced by 7-78%. CONCLUSION IDA is a known complication of recurrent bleeding events in individuals with inherited bleeding disorders. Routine monitoring for IDA may help improve bleeding management and reduce bleed burden in BSS/GT.

Abstract
Although rare clotting factor deficiencies primarily referred to as rare bleeding disorders (RBD), including factors II, V, VII, and X, make up ∼5% of all inherited bleeding disorders worldwide, each of these clotting factors play a critical role in the coagulation cascade. Incomplete bleeding evaluation or misinterpretation of laboratory studies can result in delayed diagnoses that ultimately affect patient outcomes. Bleeding manifestations can range from mild to severe, but the most common are mucocutaneous bleeding. The ideal treatment in RBD is dedicated single-factor concentrates that can be used for acute bleeding events, surgical management, and prophylaxis.

Abstract
BACKGROUND von Willebrand disease (vWD) is a heterogeneous hereditary bleeding disorder and is associated with risk of primary postpartum haemorrhage (PPH). DESIGN AND METHODS An observational study at a tertiary referral centre in Australia of 16 women with 23 deliveries with a median age of 27.5 years (range, 21-39; IQR = 9). Median gestational age at delivery was 39 weeks (range, 35-41; IQR = 1.1). RESULTS All cases had type 1 vWD, apart from one case with type 2. Patients were managed in combined obstetrics and haematology clinics. PPH occurred in ten deliveries (44%). Intravenous desmopressin was administered in 6 cases, and IV human vWF was administered in 4 cases. Two cases with mild vWD had received oral tranexamic acid. The median Apgar score at 1 and 5 min was 9 (IQR = 1.0), while the median Apgar score at 10 min was 10.0 (IQR = 0.0). One case required transfusion of blood products postdelivery. There were no other significant complications observed. CONCLUSIONS vWD was associated with a high incidence of primary PPH. Individualised treatment to restore haemostasis, according to the severity of the disease, could achieve as possible, normal haemostasis with favourable outcomes for both mothers and their infants. Further studies to confirm our findings are warranted.

Abstract
Rare coagulation disorders (RCDs) are a group of diseases due to coagulation factors deficiency leading to life-long bleeding diathesis. The diagnosis of RCDs is challenging due to the limited knowledge of these disorders and the large heterogeneity of their bleeding patterns. The clinical symptoms of RCDs are extremely diverse in terms of bleeding type, site, severity, age at onset, and duration. The strength of the association between clotting factor activity level in plasma and clinical symptoms is also variable within each RCD. The clinical evaluation of RCDs starts with a detailed collection of clinical history and has been facilitated by bleeding assessment tools, however their effectiveness in diagnosing RCDs requires further investigation. The following laboratory diagnosis of RCDs involves coagulation screening tests, including activated partial thromboplastin time, prothrombin time, and thrombin time. After ruling out the presence of an inhibitor by mixing studies, in case of abnormal results, the specific deficiency is identified by performing one-stage clotting assays using the specific factor-depleted plasmas as substrate. In fibrinogen and FXIII deficiencies coagulation screening tests are not informative, therefore additional tests are needed. Global assays have been developed and are thought to aid in patient management, however, they are not well standardized yet. In addition to outlining the principles of clinical and laboratory diagnosis, this review explores molecular basis of RCDs and laboratory techniques for genetic analysis, and discusses the importance and effectiveness of quality control programs to ensure standardized laboratory results.

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
Given the wide heterogeneity of phenotypes and of the underlying pathophysiological mechanisms associated with the disorder, pregnancy and delivery in von Willebrand disease (VWD) represent a significant clinical challenge. The variable pattern of changes observed during pregnancy of von Willebrand factor (VWF) and factor VIII (FVIII), the protein carried by VWF, prompts a careful evaluation of pregnant women with VWD to plan the most appropriate treatment at the time of parturition. However, there are also instances during pregnancy (amniocentesis, vaginal bleeding associated with placental detachment, sudden abortion) that may require urgent hemostatic treatment to prevent bleeding. Thus, women with VWD should start pregnancy after being well characterised as to their type, subtype and treatments. Women with VWD who have VWF and FVIII basal levels >30 U/dL typically normalise these levels at the end of pregnancy and specific anti-haemorrhagic prophylaxis is seldom required. On the contrary, those with basal levels <20 U/dL usually show a lesser increase and specific treatment is required. Some women with DNA variants associated with increased clearance can be treated with desmopressin, while those unresponsive or with contra-indications to this agent need replacement therapy. For these latter women, the risk of vaginal bleeding during pregnancy may be increased and prophylaxis with VWF concentrates required. Similarly, women with type 2 VWD who maintain reduced VWF activity throughout pregnancy require replacement therapy with FVIII/VWF concentrates. Delayed postpartum bleeding may occur when replacement therapy is not continued for some days. Tranexamic acid is useful at discharge to avoid excessive lochia.

Hematol Transfus Cell Ther 2019; 41:349-355.

Abstract
Introduction Hemophilia is well known in males, but poorly recognized in hemophilia carriers, who may have a hemorrhagic tendency, and the symptoms may be frequent and severe. Few studies have been done evidencing this bleeding in female carriers of the hemophilia gene. Objectives To verify the prevalence of hemorrhagic symptoms in HC, compared to women in the general population. Material and method The articles published between October 1996 and November 2016 were searched in the PubMed, Scielo, Lilacs, Web of Science, Scopus and Cochrane Central databases. Results and discussion Seventy-five articles were found in electronic databases and 2 additional articles, through manual search in journal summaries and bibliographical references of other review articles. There is a limitation as to the number of studies that explore the association between the risk of hemorrhagic events and HC A or B. Among the few existing studies, there is a methodological difference, evidenced by control groups with distinct recruitments, divergent questionnaires and non-standardized concepts. Conclusion This review verified the existence of a higher prevalence of hemorrhagic symptoms in the HC in some outcomes, however, due to the limitations of the few studies found, there is still insufficient evidence to state that the HC has a greater hemorrhagic tendency in relation to the general population.

Abstract
OBJECTIVE Studies have demonstrated an association between ABO blood type and bleeding status. The aim of this analysis was to determine whether O blood type is associated with higher early postpartum hemorrhage (PPH) risk as compared to other blood types. STUDY DESIGN In this retrospective case-control study, data was gathered form 4,516 deliveries occurring at our institution between 2014 and 2016. Cases were categorized into one of two groups according to women's major blood type (O or non-O), and thereafter according to minor blood type (RH positive or negative). The primary outcome was early PPH which was further stratified by clinical severity according to the decrement in hemoglobin concentration after delivery. Categorical variables were compared using the χ2 test while continuous variables were compared using the student's t-test. All data were further analyzed using a stepwise logistic regression model. RESULTS 1,594 (35.3%) of 4,516 women included in this analysis had O blood type. Early PPH occurred in 44 women (2.7%) with O blood type and 65 women (2.22%) with other blood types. O blood type was not associated with an increased risk for early PPH (OR 1.24, 95% CI 0.84-1.82, P = 0.275). This lack of association remained unchanged after stratification by PPH severity. There was also no significant association between Rh blood type and the risk for early PPH (OR 0.97, 95% CI 0.44-1.4, P = 0.422). CONCLUSIONS In this cohort, O blood type was not associated with an increased risk for early PPH.

Abstract
Summary Peripartum haemorrhage remains one of the main causes of maternal mortality world-wide. The German, Austrian and Swiss Societies of Gynaecology and Obstetrics have updated the current guidelines for the treatment of peripartum haemorrhage together with the German Society of Anaesthesiology and Intensive Care Medicine and the Society of Thrombosis and Haemostasis Research. The recommendations have been the result of a thorough review of the available scientific literature and a consensus process involving all members of the guideline group. A key element of the anaesthesiological and haemostatic management is the development of a multidisciplinary standard operating procedure combining surgical as well as medical and haemostatic treatments depending on the severity of bleeding. The guideline underscores the value of clinical and laboratory diagnostics of peripartum haemorrhage as early as possible, even pre-emptively. This allows for an early identification of causes of bleeding and a specific treatment. The guideline comprises evidence-based recommendations for the use of uterotonics, tranexamic acid and blood products such as factor concentrates, fresh frozen plasma, platelet concentrates, packed red blood cells, recombinant activated factor VII and desmopressin. In addition, recommendations for blood conservation strategies involving the use of cell salvage, permissive hypotension and transfusion triggers are given.

Abstract
: Hemophilia A carriers have an abnormal X chromosome with a molecular abnormality of FVIII gene. These carriers, long considered to be free of bleeding risk, could have the same symptoms as mild hemophiliacs. This study aim to assess bleeding risk of hemophilia A carriers monitored at the Clinical Hematology Department of Dakar. This is a prospective study of a period of 6 months including 22 hemophilia A carriers aged between 8 and 48 years. Hemophilia carriers were recruited using the genealogical tree of hemophiliacs followed in the service. Their diagnosis was carried out by long range PCR and Sanger sequencing method searching the molecular abnormality responsible for hemophilia in their family. Bleeding risk was determined using a questionnaire consisting of different bleeding symptoms quoted from -1 to 4 according to the severity. Total of different values allow to determine the bleeding score which was pathological if it was greater than or equal to 1. Medium age was 22.5 years (8-48) (SD = 9.28). Four hemophilia A carriers (18.1%) presented bleeding symptoms and had a bleeding score at least 1 (P = 0.02). Menorrhagia was predominant (13.6%) followed by epistaxis (9%), gingivorrhagia (9%), and prolonged bleeding after tooth extraction (9%). Factor VIII level was lower in hemophilia carriers who presented bleeding (42 ± 8.61 UI/l) versus hemophilia carriers without bleeding (100 ± 50.95 UI/l) (P = 0.001). There was no significant correlation between bleeding occurrence and age (P = 0.81), activated patial thromboplastin time value (P = 0.97) and FVIII/Von Willebrand Factor ratio (P = 0.12). One in five hemophilia carriers presented bleeding and the questionnaire was effective to identify hemophilia carriers who had a risk of bleeding.

Abstract
Introduction von Willebrand disease (VWD) is a hereditary bleeding disorder, caused by a deficiency in the levels and/or function of von Willebrand factor (VWF). Women with VWD appear to be at increased risk of experiencing postpartum hemorrhage (PPH), though the levels of VWF increase during pregnancy. There is limited knowledge of how PPH is associated with the subtype of VWD, plasma levels of other coagulations factors than VWF and given hemostatic treatment. Aims The aims were to investigate the incidence of PPH in women with VWD and to analyse the correlation between PPH and: (1) type of VWD, (2) laboratory monitoring of VWF and FVIII and (3) hemostatic drug treatment. Methods This was a retrospective observational study. The study participants (n = 34) were recruited from the Coagulation Unit, Karolinska University hospital. Fifty-nine deliveries, which occurred in 14 different obstetrics units (years 1995–2012) were included in the study. Results The incidence of primary PPH was 44%, severe primary PPH 20% and secondary PPH 12%. VWD type 3 was associated with a higher risk of experiencing severe primary PPH compared to other subtypes. FVIII:C in pregnancy was inversely correlated to blood loss during delivery. There was a significantly higher incidence of secondary PPH when the VWD diagnosis was unknown at time of delivery. Conclusions The women with VWD are at higher risk of PPH, especially those with type 3 VWD or when diagnosis is unknown prior to delivery. Identification of pregnant women with undiagnosed VWD may be of importance in order to prevent PPH.

Abstract
AIM The aim of this study was to examine the association between maternal inherited bleeding disorders and neonatal complications. MATERIAL AND METHODS This was a historical cohort study. The rare inherited bleeding disorders (RIBD) group consisted of a total of 100 women suffering from inherited bleeding disorders, aged 20-45 years who experienced pregnancy. In the healthy control group, 200 age- and body mass index-matched women were selected. Details of demographic and obstetric characteristics of the samples in both groups were collected using their medical records. RESULTS The mean ages of the women in the RIBD and healthy control groups were 32.6 (7.07) and 32.4 (7.3) years, respectively. No statistically significant differences were found in terms of age and other demographic characteristics of the women between the groups. The mean neonatal birthweight in the RIBD group was statistically lower than that in the healthy control group, 3018.2 (546.9) g vs. 3299.4 (456.8) g, respectively (P = 0.021). The prevalence of low birthweight in the RIBD group was statistically higher in comparison to that in the healthy control group (P = 0.041). After adjustment for potential confounders, it was found that maternal bleeding disorder had significant negative effects on birthweight in newborns (odds ratio, 1.05; 95% confidence interval, 1.01-3.43, P = 0.001). Those infants were statistically more likely to experience head bleeding, early hyperbilirubinemia and hospitalization than the healthy group (P = 0.001). CONCLUSIONS Maternal rare inherited bleeding disorders may have a devastating consequence for neonates.

Abstract
In excess of 200 people with hemophilia (PWH) and their families have received genetic counseling (GC) at the Hemophilia Comprehensive Care Centre at Charlotte Maxeke Johannesburg Academic Hospital. However, very few of their at-risk female relatives have attended GC to discuss their reproductive risks and options, or their potential bleeding risks. Limited research has been conducted internationally on factors influencing uptake of GC and testing amongst female relatives of PWH. This prospective study aimed to explore the factors that influence the uptake of GC and testing by female relatives of PWH. An open-ended semi-structured interview schedule was developed. Participants included female relatives of PWH who at least had a family member who had received GC. Seventeen participants were interviewed; 7 who had GC previously and 10 who had not. All participants who had previously received GC found the service helpful and were mothers referred because their sons had hemophilia. Of those who had not had GC, possible deterrents included: being unaware of GC service, focus in clinic on PWH and not potential carriers, misunderstood risks related to hemophilia and carrier status, fear of finding out carrier status, and non-disclosure in families. Most participants were unaware of potential bleeding risks for carriers. The information will be used to provide a better service to female relatives of PWH with a goal being to set up a dedicated hemophilia carrier clinic.

Abstract
Rare bleeding disorders (RBDs) are inherited deficiencies of coagulation factors such as fibrinogen, factor (F) II, FV, FVII, combined FV+FVIII, FX, FXI and FXIII. These disorders usually have a low prevalence in the general population and constitute approximately 3-5% of all coagulation disorders. However, in some countries they may have the same prevalence as haemophilia B due to the practice of consanguineous marriage. The clinical picture of RBDs is highly variable and can vary markedly from mild to severe, making both diagnosis and optimal treatment quite challenging. This review focuses on: (i) the efforts to establish a bleeding assessment tool adequate to RBDs, (ii) the optimal management of patients affected with FXI deficiency and (iii) the correlation between clinical severity and laboratory diagnosis when determining the minimum coagulant activity required to prevent bleeding in each RBD.

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.

Changes of von Willebrand Factor during Pregnancy in Women with and without von Willebrand Disease. Mediterr J Hematol Infect Dis 2013; 5:e2013052.

Abstract
Delivery in von Willebrand disease (VWD) represents a significant hemostatic challenge because of the variable pattern of changes observed during pregnancy of von Willebrand factor (VWF) and factor VIII (FVIII), the protein carried by VWF. Since a wide heterogeneity of phenotypes and of the underlying pathophysiological mechanisms is associated with this disorder, a prompt and careful evaluation of pregnant women with VWD is requested in order to plan the most appropriate treatment at time of parturition. VWF and FVIII increase significantly during pregnancy in normal women, already within the first trimester, reaching levels by far >100 U/dL by the time of parturition. Women with VWD, levels at baseline of VWF and FVIII >30 U/dL have us a high likelihood to achieve normal levels at the end of pregnancy; thus specific anti-hemorrhagic prophylaxis is seldom required. Women with basal level <20 U/dL usually have a poor increase since most of these women carry mutations associated with increased VWF clearance or are compound heterozygous for different VWF mutations; that prevent the achievement of satisfactory hemostatic levels. While women with mutations associated with increased clearance show a full, albeit transitory correction of their hemostatic deficiency after desmopressin administration, compound heterozygous need replacement therapy because they do not respond well to this agent. Patients with abnormal VWF:RCo/VWF:Ag ratio at baseline (e.g. <0.6), typically associated with type 2 VWD, maintain the abnormality throughout pregnancy and VWF:RCo usually does not attain safe levels ≥50 U/dL. These women require replacement therapy with VWF-FVIII concentrates. Delayed post-partum bleeding may occur when replacement therapy is not continued for some days. Tranexamic acid may be useful at discharge to avoid excessive lochia.

Abstract
Quantification of the bleeding severity by use of bleeding assessment tools (BAT) and bleeding score (BS) has been consistently shown to improve the clinical diagnosis of von Willebrand disease (VWD) while helping researchers establish phenotype/genotype correlations. Subjects with a BS equal or higher than 3 may be consider having a bleeding tendency, and should be referred for a laboratory investigation, particularly for VWD. In the diagnosis of type 1 VWD, the use of the BS has been shown to be highly specific (>95%) with reported sensitivities ranging from 40 to 100%. The BS is related to all available measurements of von Willebrand factor activity, including the PFA-100 closure time. Therefore, in clinical practice the use of BAT should always be the first step to standardize the assessment of patients with suspected VWD. The use of the recent ISTH consensus BAT is suggested to harmonize the collection of bleeding symptoms in patients with a suspected or confirmed hemostatic disorder, particularly VWD. The ISTH BAT is also coupled with a Web-based repository of bleeding symptoms, therefore providing an integrated framework for collaboration in the field of clinical evaluation of VWD and mild bleeding disorders.

Abstract
Inherited bleeding disorders are caused by various genetic defects in the proteins involved in haemostasis. Female patients or carriers are faced with the risk of haemorrhage throughout life. During pregnancy and postpartum, this complication affects the health of either the mother or the baby, or both. This retrospective cohort study was designed to assess the occurrence of obstetric bleeding in the three trimesters of pregnancy, along with primary and secondary postpartum haemorrhage among 100 women with inherited bleeding disorders. A questionnaire was designed in order to collect historical data. The patients were evaluated in three groups: haemophilia carriers, von Willebrand disease (VWD) and rare bleeding disorders. In comparison with normal women, significantly severe bleeding was observed among patients in all of the five stages. VWD patients showed a higher frequency of bleeding in first trimester but the rate of miscarriage was lower. Haemophilia carriers were threatened with bleeding complications during the prenatal period, but they also had the highest frequency of postpartum haemorrhage. Based on our results, vaginal bleeding is a serious threat in all three patient groups, especially during the first trimester of pregnancy and in the postpartum period.

Abstract
Women with inherited bleeding disorders present a wide spectrum of clinical symptoms that vary from mild or moderate bleeding tendency to severe episodes. Monthly haemostatic changes affect these women during menstruation and ovulation. These events may be associated with significant bleeding and pain leading to the limitations in conducting daily activities and adverse effect on quality of life. Likewise, pregnancy and delivery are critical times for affected women. During pregnancy, they may be at greater risk of miscarriage and bleeding complications. In particular, recurrent miscarriage was observed in women with type 3 von Willebrand disease, afibrinogenaemia and severe factor XIII deficiency, and an optimal therapeutic plan is required during their pregnancy. Precautions must be taken at delivery in these women, since they could be at risk of bleeding. The lack of adequate information makes it very difficult to prepare evidence-based guidelines for the prevention of bleedings in affected women and their treatment. A multidisciplinary team of obstetricians, haematologists and paediatricians is required with a good knowledge of these disorders and an awareness of the potential maternal neonatal complications.

Abstract
Patients affected by bleeding disorders present a wide spectrum of clinical symptoms that vary from a mild or moderate bleeding tendency to significant episodes. Women with inherited bleeding disorders are particularly disadvantaged since, in addition to suffering from general bleeding symptoms, they are also at risk of bleeding complications from regular haemostatic challenges during menstruation, pregnancy and childbirth. Moreover, such disorders pose important problems for affected women due to their reduced quality of life caused by limitations in activities and work, and alteration of their reproductive life. These latter problems include excessive menstrual bleeding or menorrhagia, miscarriage, bleeding complications during pregnancy and after delivery and their related complications such as acute or chronic anaemia. The management of these women is difficult because of considerable inter-individual variation. Moreover, reliable information on clinical management is scarce, only a few available long term prospective studies of large cohorts provide evidence-based guideline about diagnosis and treatment.
