Abstract
The search for hereditary bleeding disorders (HBD) prior to invasive procedures in children is primarily based on personal and family bleeding history. Although several scores are available, they have only been evaluated in specific situations or in adults. Our monocentric retrospective study aimed to analyze the association between clinical history and four scores (HEMSTOP, PBQ, ISTH-BAT, TOSETTO) and the diagnosis of MHC in children referred to the University Hospital of Montpellier for hemostasis investigations. A total of 117 children were retrospectively included in the study. Of these, 57 (49%) were diagnosed with HBD, with 30 having primary bleeding disorders and 27 having coagulation disorders. The diagnosis of HBD was significantly associated with gingival bleeding, which was present in 30% of HBD patients. In our population, only the HEMSTOP score showed an association with the diagnosis of HBD, but it was positive in only 48% of patients. By including gingival bleeding as a factor, we modified the HEMSTOP score, which increased its sensitivity from 0.45 to 0.53. When examining primary bleeding disorders, the modified HEMSTOP score, with the inclusion of gingival bleeding, enables us to diagnose 63% of patients (see Fig. 1). Conclusion: Therefore, gingival bleeding should be considered a useful factor in bleeding history for HBD diagnosis. Adding this symptom to a screening score such as HEMSTOP improves its sensitivity. To confirm our findings, a prospective study is required. Trial registration: Study registration number: NCT05214300. What is Known: • Screening for hereditary bleeding disorder diseases is a necessity and a challenge in children. • Minor disorders of primary hemostasis are the most common, but often escape standard coagulation tests. What is New: • Gingival bleeding is a frequent symptom that is easy to investigate and may point to a primary hemostasis disorder. • Adding the gingival bleeding item to a routine screening score such as HEMSTOP improves sensitivity.

Abstract
INTRODUCTION At a population level, there is a poor understanding of the incidence and pre-disposing risk factors of postpartum haemorrhage (PPH) among women with inherited bleeding disorders (IBD). AIM To determine the incidence of PPH, and identify maternal factors associated with risk of PPH among women with IBD. METHODS We conducted a retrospective cohort study using data housed within ICES (formerly known as the Institute for Clinical Evaluative Sciences). The cohort included women with an in-hospital, live or stillborn delivery, between January 2014 and December 2019. The primary outcome was PPH (identified by ICD-10 code O72). PPH incidence and risk factors were compared between women with and without IBD. Temporal trends were assessed using the Cochrane-Armitage test. Between group differences were assessed using standardised differences (std. difference). RESULTS Total 601,773 women were included; 2002 (.33%) had an IBD diagnosis. PPH incidence was 1.5 times higher (7.3 vs. 4.9 cases/100 deliveries, std. difference .1) among women with IBD compared to women without. Women with IBD were slightly older (31.7 vs. 30.7 years), had higher rates of hypertension, previous PPH, and induction of labour. Women with IBD were more frequently diagnosed with anaemia (4.8% vs. 1.8%; std difference .17) and had lower haemoglobin levels at admission for delivery compared to women without IBD. CONCLUSIONS This study contributes to the literature regarding obstetric bleeding among women with IBD, showing that anaemia at delivery may be an important risk factor for PPH. Given their predisposition to anaemia, clarifying this relationship will optimise management and outcomes.

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
Osteonecrosis of the femoral head (ONFH) is a debilitating disease with major social and economic impacts. It frequently affects relatively young adults and has a predilection for rapid progression to femoral head collapse and end-stage hip arthritis. If not diagnosed and treated properly in the early stages, ONFH has devastating consequences and leads to mandatory total hip arthroplasty. The pathophysiology of non-traumatic ONFH is very complex and not fully understood. While multiple risk factors have been associated with secondary ONFH, there are still many cases in which a clear etiology cannot be established. Recognition of the prothrombotic state as part of the etiopathogeny of primary ONFH provides an opportunity for early medical intervention, with implications for both prophylaxis and therapy aimed at slowing or stopping the progression of the disease. Hereditary thrombophilia and hypofibrinolysis are associated with thrombotic occlusion of bone vessels. Anticoagulant treatment can change the natural course of the disease and improve patients' quality of life. The present work focused on highlighting the association between hereditary thrombophilia/hypofibrinolysis states and ONFH, emphasizing the importance of identifying this condition. We have also provided strong arguments to support the efficiency and safety of anticoagulant treatment in the early stages of the disease, encouraging etiological diagnosis and prompt therapeutic intervention. In the era of direct oral anticoagulants, new therapeutic options have become available, enabling better long-term compliance.

Abstract
INTRODUCTION Heavy Menstrual Bleeding (EMB) is a frequent problem in adolescence. The prevalence of inherited bleeding disorders (IBD) as a cause of EMB is not well established and the involvement of fibri nolytic pathway defects has been poorly explored. OBJECTIVE To determine the prevalence of IBD and fibrinolysis defects in adolescents with EMBs. PATIENTS AND METHOD 93 adolescents (11 to 18 years old) were included. Personal and family history of bleeding were obtained through a standard ized questionnaire. The following lab tests were performed: prothrombin time (PT), activated partial thromboplastin time (aPTT), von Willebrand factor quantification, and platelet count and function. Those patients who were not diagnosed with IBD were further evaluated with clot lysis time assay. RESULTS 41 patients (44%) were diagnosed as IBD (Von Willebrand disease n = 28, platelet func tion defects n=8, mild hemophilia n = 5. Decreased clot lysis time was found in 31 patients. 54% of patients diagnosed with IBD had EMB as the first hemorrhagic manifestation. CONCLUSION These results support the need to evaluate the coagulation process, including the fibrinolytic pathway in the study of adolescents with EMB.

Abstract
Functional limitations for the vitamin K cycle, caused either by mutations in gamma-glutamyl carboxylase or vitamin K epoxide reductase genes, result in hereditary deficiency of vitamin K-dependent coagulation factors (VKCFD1 and VKCFD2, respectively). Patients suffering from VKCFD often share several other anatomical irregularities which are not related to haemostasis. Here we report on nine patients, eight of them previously unreported, who presented with VKCFD1. All were examined with special attention to vitamin K-dependent coagulation factors as well as to bone and heart development and to other anatomical signs of embryonal vitamin K deficiency. In total, we detected ten mutations in the gamma-glutamyl carboxylase gene of which seven have not been previously reported. Most interestingly, additional non-bleeding phenotypes were observed in all patients including midfacial hypoplasia, premature osteoporosis, cochlear hearing loss, heart valve defects, pulmonary stenosis, or pseudoxanthoma elasticum-like phenotype. Undercarboxylated matrix Gla protein, osteocalcin, and periostin appear to be responsible for these defects which are also observed in cases of fetal warfarin syndrome.

Abstract
The clinical histories of 45 consecutively performed TKAs in 32 patients with hereditary bleeding disorders were reviewed retrospectively. The mean follow up was 88.7 (range, 24-232) months. The cumulative probability of infection free-survival was 87.8% after 180 months. When removal of component was defined as endpoint, the survival probability was 86.4% after 180 months. In regression analysis no significant independent risk factors for infection or aseptic loosening were identified. The HSS score improved significantly from 45 to 85 points. Hemophilic patients can be considered to be at high risk for prosthetic failure, our study has demonstrated favorable functional results of total knee arthroplasty in hemophilic patients.

Abstract
BACKGROUND Arthropathy of the knee is a frequent complication in patients with severe bleeding disorders leading to considerable pain and disability. Total knee arthroplasty (TKA) provides marked pain relief. However, a modest functional outcome and a high number of complications due to prosthetic infection and loosening are reported. Data on long-term outcomes are scarce, and most case series include few patients. We have studied clinical outcomes and complications of TKAs with special emphasis on prosthetic survival and periprosthetic infection. METHODS A consecutive series of 107 TKAs in 74 patients with haemophilic arthropathy were retrospectively reviewed. Follow-up was mean 11.2 years (range 0.8-33.1 years). RESULTS Five- and 10-year survival rates, with component removal for any reason as the end point, were 92% and 88%, respectively. Twenty-eight TKAs were removed after median 10 years (range 0.8-28 years). The most common cause of failure was aseptic loosening (14 knees) and periprosthetic infection (seven knees). The overall infection rate was 6.5%. The mean postoperative drop in haemoglobin levels was 4.3 g/dL (range 0.5-9.4) with a significant difference between haemophilia A patients with and without inhibitor (6.3 g/dL (range 3.6-9.4) versus 3.7 g/dL (range 0.5-8.1) (p<0.001). A painless knee was reported in 93% of the TKAs at the latest follow-up. CONCLUSIONS The medium and long-term results of primary TKA in a large haemophilic population show good prosthetic survival at five and 10 years with an excellent relief of pain. Periprosthetic infection is still a major concern compared to the non-haemophilic population. LEVEL OF EVIDENCE Level IV.

Abstract
OBJECTIVE The aim of this study was to assess the effectiveness of localized treatments to persistently stop epistaxis in patients with inherited bleeding disorders. METHODS In a self-controlled comparative clinical trial, to offer the best solution to stop epistaxis at home (within 10 minutes), patients with inherited bleeding disorders were treated using three different topical hemostatic agents, including Tranexamic acid impregnated tampon, EpiCell tampon prepared from oxidized regenerated cellulose pad, and ChitoHem tampon (reinforced with chitosan). The results of using these different products on three groups of randomly selected patients were ultimately compared using the χ(2) and Fisher's exact test statistics. RESULTS A total of 31 patients, 5 females and 26 males with a mean age of 5.6 years, were included in the study. Twenty-three patients had Glanzmann disease, four had von-Willebrand disease, two had Bernard soulier syndrome, two had activated factor VII deficiency, and one patient had impaired secretion of adenosine deaminase. The study exhibited that statistically there was no significant difference between EpiCell tampon and Tranexamic acid impregnated tampon treatments with respect to the hemostasis duration. However, ChitoHem tampon was more efficient than Tranexamic acid impregnated tampon (P value <0.001) and EpiCell tampon (P value < 0.05). CONCLUSION ChitoHem tampon, the chitosan-reinforced product, was the best therapy solution to stop epistaxis. We recommend further research on the use of other hemostatic agents for localized bleeding in patients with inherited bleeding disorders.

Abstract
The main clinical features of nephrotic syndrome (NS) are heavy proteinuria, hypoalbuminemia, hyperlipidemia and edema. In addition, multiple abnormalities in the coagulation pathway may be a consequence of the NS. Both arterial and venous thromboembolic complications (TEC) are relatively common and serious consequences of NS. In addition, arterial and venous thrombosis might be unexpected events during an exacerbation of NS. Embolic episodes may manifest in different regions of the body such as the brain or the lung. Hence, predisposing factors, personal and family history of TEC, thrombosis location and evolution should be always investigated in children with NS.

Abstract
Budd Chiari syndrome or hepatic venous outflow obstruction is a complex entity with multiple etiologies and various clinical manifestations. It is often difficult to establish the diagnosis. The most common cause is a hypercoagulable state due to either genetic disorders of blood coagulation or several acquired conditions such as hematological diseases, tumors, infections, chronic inflammatory diseases, pregnancy. The most common clinical presentation is hepatomegaly, abdominal pain and ascites, but the onset can also be dramatical and life threatening with upper digestive bleeding due to portal hypertension through postsinusoidal blockage. We report the case of a young patient with a coagulation disorder secondary to a mutation of factor V Leiden, who presented with upper digestive bleeding as the first manifestation of Budd Chiari syndrome and who also was associated with myocardial infarction in his past medical history.

Abstract
BACKGROUND Menstruations, by their abundance and their duration, can be a source of impaired quality of life. Women with inherited bleeding disorders appear to be, specially at risk. AIM Assess the impact of menstrual blood loss on the quality of life for women with inherited bleeding disorders. METHODS 31 women with various inherited bleeding disorders were interviewed. They completed a quality of life questionnaire. RESULTS Von Willebrand disease was the most frequent inherited bleeding disorder in our population (38.7%). 54.8% of patients had a menstrual period more than 6 days 61.3% of them consider their menstrual flow to be normal. The general condition apart of the menstrual period was considered medium to poor in 35.5% of patients. The average score assessing the impact of menstruation on daily life was of 5.00 ± 3.47. Only 19.35% of patients felt that dysmenorrhea significantly affect their quality of life. Impaired quality of life was seen in 64.5% of patients according to score Aand in 41.9% of them according to score B. During menstruation 22.6% of the patients didn't do to work or to school because of the menstrual flow. On the other hand, 48.4% of patients were hospitalized at least once for a heavy menstrual flow. CONCLUSION The quality of life during menstruation, in women with an inherited bleeding disorder, according to the different scores appear altered. Although because of the small size of our study population, we could not prove correlation between the importance of menstrual blood loss and the impairment of quality of life.

Abstract
BACKGROUND Intracranial hemorrhage (ICH) is a life-threatening situation in childhood. Congenital factor deficiencies (CFD) like hemophilia may cause ICH, and ICH may be the initial presentation in some cases. METHODS From 2000 to 2010, 107 children with CFD from Erciyes University, Faculty of Medicine, Department of Pediatric Hematology, were evaluated. The ICH episodes were identified by medical history, general physical examination, detailed neurological examination, and CT or MR scan. The management strategies, surgical intervention, and outcome were noted. RESULTS Twenty-one episodes of ICH were seen in 18 patients (16.8%) out of 107 CFD patients. The mean age of the patients was 42.1 months. Fourteen out of 18 patients were male, and four were female. Twelve (57.1%) out of 21 ICH episodes were caused by trauma, and nine (42.9%) were non-trauma related. Epidural hematoma was most frequently observed. All patients survived, but four had decrease in intellectual capacity and motor deficit. CONCLUSION The optimal management of ICH in children with CFD depends on immediate recognition and prompt replacement therapy to ensure hemostatic balance with adequate surgical intervention.

Abstract
This case report describes a case of venous thrombosis in a young woman who had undergone tympanoplasty due to chronic otitis media. Other than that she was healthy. According to the anamnesis she stopped taking oral contraceptive pills (OCP) a month before the surgery. She did not receive thromboprophylaxis before the surgery because it was estimated that there was a low risk for a thromboembolic incident. Several hours after the surgery she was still not responding properly to external stimulus and there was no verbal contact. An urgent computed tomography (CT) scan of head and neck revealed thrombosis of the left internal jugular vein. She was admitted to the Intensive Care Unit (ICU) and heparin therapy started. After a few days she was fully recovered. Later it was confirmed that the patient had an inherited fibrinolysis disorder caused by plasminogen activator inhibitor 1 (PAI-1) gene polymorphism. Our opinion is that the unexpected thrombotic incident was a result of interaction of multiple factors, including the venous stasis at the surgery site, decreased fibrinolysis ability, and the prothrombotic effect of OCP.

Abstract
Acquired and inherited platelet disorders can present with bleeding symptoms during adolescence. Platelet disorders include disorders of platelet number and disorders of platelet function. In adolescent females with platelet disorders, menorrhagia is a common presenting bleeding symptom. Other associated bleeding symptoms are also primarily mucocutaneous, including epistaxis and bruising. Excessive bleeding may also occur after hemostatic challenges. Diagnosis of disorders of platelet function usually requires light transmission platelet aggregometry. Management of menorrhagia in the adolescent with platelet disorders requires both hematologic and gynecologic treatment.

Abstract
The occurrence of thrombotic events in patients with congenital bleeding conditions has received considerable attention in recent years. The same is true for asymptomatic defects of factors of the contact phase of blood coagulation, mainly FXII. Anecdotal reports on thrombosis in patients with prekallikrein deficiency have occasionally been reported. These involved both arterial and venous thrombosis. The purpose of the present article is to analyze the stories and the clinical pictures of all 75 cases of prekallikrein deficiency published so far. Among these patients were 9 with thrombosis, 6 arterial (myocardial infarction and ischemic stroke) and 3 venous (deep vein thrombosis with or without pulmonary embolism). In 6 cases acquired thrombosis risk factors were present; in 2 cases no associated risk factors were present and in 1 case no information was supplied in this regard. One patient who presented both a stroke and a pulmonary embolism had a fatal outcome. The article clearly indicates that prekallikrein deficiency does not protect from thrombosis in spite of the severe in vitro coagulation defect.

Abstract
OBJECTIVE To study the clinical characteristic, presentation, complications in patients with congenital coagulation disorders who attended the Congenital Coagulation Disorders Center, Baghdad, Iraq. METHODS This cross-sectional study was conducted in the Center of Congenital Coagulation Disorders, Al-Mansour Pediatric Teaching Hospital, Baghdad, Iraq between March 2008 and August 2008. The sample comprised 243 patients with different congenital coagulation disorders. We collected the data through structured questionnaire form and carried out the physical examination of the patient under the supervision of the physician-in-charge at the center. RESULTS Hemophilia and Von Willebrand Disease (VWD) constituted 90.1% of the sample, while rare bleeding disorders constituted 9.9%. Most patients (82.7%) have had onset of symptoms during the first year of life. Clinically, 52.7% of patients presented with hemarthroses were hemophiliacs and factors X deficiency. This distribution was also true for joint limitations. CONCLUSION Most patients were hemophiliacs and the highest prevalent of symptom was 6-12 months old, and the diagnosis of the disease was highest within one month after the onset of symptoms. Most patients with joint limitation was hemophiliacs and approximately 50% had limitation of 3 or more joints.

Abstract
The prevalence of menorrhagia in adolescent populations with bleeding disorders varies between 14% to 48%. The common conditions associated with menorrhagia include von Willebrand disease (VWD), platelet function disorders and coagulation factor deficiencies. The majority of studies, which have been conducted in the West, report VWD, as the most common inherited bleeding disorder leading to menorrhagia, whereas studies from South-East Asia have found platelet function disorder as the leading inherited bleeding disorder in women with menorrhagia. The other common conditions which can lead to increased blood loss in this age group are anovulatory bleeding and hormonal disorders. We report here three cases of adolescent menorrhagia due to platelet function disorders, along with review of literature.

Abstract
With early prophylactic treatment our haemophilic children grow up in good health. Nevertheless, we cannot prevent every bleeding. Those bleedings may be just subclinical but they could lead to overloading of the knee and more and more of the ankle joint in the long term. Motion analysis can help to understand this process and prevent it. A comparison of the gait function of haemophilic and healthy children of the age 3-18 years showed distinct functional differences especially in the youngest age group (3-6 years). Apparently, the coordination skill gait rhythm was significantly worse in the heamophilic group. All measured functional deficits can be treated with physiotherapy. Possible reasons for these early functional differences are overprotection and/or early subclinical bleedings.

Abstract
Since 1978 an annual multicentric survey regarding the epidemiology of patients suffering of haemophilia is performed with support of haemophilia treating centres of any size. Again the actual compilation is resting upon a broad database returning to over 30 years of inquiry well representing both the actual and retrospective status of mortality. Prompted was exclusively information about patients with haemophilia A, B and von Willebrand disease. In particular anonymous data concerning the last 12 months about number of treated patients, type and severity of illness, HIV-status and detailed information about causes of death was inquired. This data was merged with existing data and analyzed statistically. In the 2007/2008 survey, a total number of 8904 patients with bleeding disorders have been reported from 63 participating centres. Despite mortality from HIV in patients with haemophilia is keeping on decreasing, HIV still remains an important factor as an HIV/HCV coinfection seems to increase risk of progression of severe liver disease. Age structure in our patients has been shifting significantly over the last decades bringing age distribution into line with the entire population. This has to be considered assessing mortality and morbidity.

Abstract
Hemospermia is usually a symptom of urological relevance, however it may have also a medical and hematological significance and has been reported in congenital or acquired bleeding disorders. Because of this symptom's negative psychological impact on the patient, it is likely that the condition is underplayed and therefore underdiagnosed. During the years 1967-2003 we had the opportunity to see 3 patients with hemospermia on a congenital bleeding disorder: a patient with hemophilia A, another with prothrombin deficiency and finally a patient with von Willebrand disease type I. All patients were heterosexual. In all instances the course was benign since it required administration of substitution therapy on only 2 occasions. Rest and abstinence from sexual activity appeared to be helpful. The first patient had other signs and symptoms compatible with the diagnosis of urethritis due to Escherichia coli and he underwent a course of antibiotic therapy. The other 2 cases appeared to be idiopathic since no associated condition was found. Urinary cytology, rectal examination, prostate sonography and prostate-specific antigen were normal in all cases. The rarity of hemospermia in congenital bleeding disorders remains unexplained, although the strong perineal and sphincter muscles may exercise a compressive hemostatic effect which could prevent or reduce bleeding.

Abstract
Intramedullary spinal cord hemorrhage (hematomyelia) is an uncommon cause of myelopathy and can present in an acute, subacute, stepwise, or chronic fashion. Spinal vascular malformations such as intramedullary cavernomas and intradural arteriovenous malformations are the most common cause of atraumatic intramedullary spinal cord hemorrhage based on the existing literature. Additional considerations include warfarin or heparin anticoagulation, hereditary or acquired bleeding disorders, primary spinal cord tumors, spinal cord metastases, Gowers' intrasyringal hemorrhage, or a delayed complication of spinal radiation. Prompt diagnosis of hematomyelia first requires recognition of a myelopathy syndrome (transverse, central, anterior, posterior, or hemi-cord) often accompanied by sudden, severe back or neck pain and sometimes radicular pain. MRI with and without gadolinium is the preferred imaging modality. There are no clinical trials to guide the management of acute intramedullary spinal cord hemorrhage, and subsequent treatment is usually directed toward the underlying cause.

Abstract
BACKGROUND Pre-peri-menarchal diagnosis of polycystic ovary syndrome (PCOS) is important, because intervention with metformin-diet may prevent progression to full blown PCOS. HYPOTHESIS In 25 girls age < or =14 years with probable familial PCOS, 10 pre-, 15 post-menarchal, 13 with precocious puberty, 23 with a first-degree relative with PCOS, we hypothesized that reversible coronary heart disease (CHD) risk factors, insulin resistance, clinical and biochemical hyperandrogenism, and hypofibrinolysis were already established. METHODS Fasting measures: insulin, glucose, total, LDL- (LDL-C), and HDL-cholesterol (HDL-C), triglycerides (TG), systolic and diastolic blood pressure (SBP, DBP), plasminogen activator inhibitor activity (PAI-Fx), total (T) and free testosterone (FT), androstenedione, and DHEAS. RESULTS Clinical and/or biochemical hyperandrogenism was present in all 25 girls, with elevations of T or FT, or androstenedione in seven of ten pre-menarchal girls and in all 15 post-menarche. PAI-Fx was high in 28% of the 25 girls vs 6.5% in age-gender-race matched controls (p = 0.013). Categorized by race-age-specific distributions in 870 schoolgirls, the 25 girls with probable familial PCOS were more likely to have top decile body mass index (BMI), insulin, HOMA-insulin resistance (HOMA-IR), SBP, DBP, and TG, and bottom decile HDL-C. By analysis of variance, adjusting for race, age and BMI, PCOS girls had higher FT and waist circumference than controls, but did not differ for SBP, DBP, HDL-C, or TG (p>0.05). CONCLUSIONS Pre-peri-menarchal acquisition of centripetal obesity amplifies CHD risk factors and hypofibrinolysis in hyperandrogenemic girls with probable familial PCOS and precocious puberty. When schoolgirls become as obese as girls with probable familial PCOS, they acquire the same CHD risk factors, and differ only by lower free T and less centripetal obesity.

Abstract
Chronic hepatitis C (CHC) and end-stage liver disease are becoming an increasingly common cause of mortality in patients with congenital bleeding disorders, especially in the HIV-coinfected group. Combination of pegylated interferon (Peg-IFN) and ribavirin has recently become the treatment of choice for CHC. In this study, we evaluated the safety and efficacy of combination therapy with Peg-IFN plus ribavirin for the treatment of CHC in human immunodeficiency virus (HIV)- and HIV+ patients with congenital bleeding disorders. Between 2000 and 2004, 50 (18-68 years old) patients with CHC (19 HIV+) from two hemophilia centers were included in the study. They were treated with weekly subcutaneous administration of Peg-INF-alpha combined with 800-1,200 mg ribavirin daily, for 24-48 weeks depending on viral genotype. Response was evaluated at weeks 12, 24, 48 (end of treatment response) and 72 had sustained virological response). Overall, 22/50 patients (43.8%) had end of treatment response and 20/50 (40%) sustained virological response. HIV- patients responded similarly to the general population (58.1%), while HIV+ patients had very low response rates (10.5%). The high rate of discontinuation (36.9%) as a result of side effects contributed to the observed low response rate in the HIV+ group. The only factor strongly associated with sustained virological response in the HIV- patients was the reduction of HCV RNA at 12 weeks (p = 0.001). Patients with viral genotypes other than 1 had higher SVR rates, but this was not found to be statistically significant. Peg-INF plus ribavirin is safe for the treatment of CHC monoinfected patients with inherited bleeding disorders, with similar response rates to nonhemophiliacs. On the contrary, in HIV coinfected hemophilic patients under highly active antiretroviral therapy it is associated with severe toxicity and very poor sustained virological response rates. Careful evaluation and several considerations are needed before starting treatment in this population.

Abstract
Hemostatic disorders in women are frequently associated with long-standing menorrhagia. This leads to significant morbidity and adversely affects quality of life. Management of these women poses a particular challenge; medical treatments may be contraindicated, and surgery carries additional risks. The levonorgestrel intrauterine system (LNG-IUS) has been shown to be highly efficacy in reducing menstrual blood loss in women with normal coagulation. It is also a reliable and reversible contraceptive. Data on the use of this system in women with bleeding disorders or those receiving anticoagulant therapy are limited. Analysis of data from four reported studies suggests that LNG-IUS is a viable and safe option for the management of menorrhagia in these women. Whether the underlying hemostatic disorders lead to a shorter duration of action or prolonged irregular bleeding/spotting post insertion is unknown and requires large prospective studies. Proper counselling remains crucial for patients' satisfaction.

Abstract
There is compelling evidence that use of oral formulations of female hormone replacement and of the combined oral contraceptive induces a prothrombotic state. This translates to an increased thrombotic risk. Within the individual, the absolute risk is determined by the interaction between that induced by hormone use and heritable and acquired risk factors for thrombosis. Knowledge of the accumulating epidemiologic and clinical trial-derived data on this topic is essential for the delivery of evidence-based counseling in the clinical environment and is the subject of this review.

Abstract
Heritable thrombophilia is associated with an increased risk for pregnancy failure, defined as sporadic and recurrent miscarriage, late fetal loss, and other vascular pregnancy complications such as preeclampsia and intrauterine growth retardation. The pathogenesis is likely to include effects on trophoblast differentiation and not solely hypercoagulability. This is in line with the observation that most recurrent miscarriages occur early. Therapeutic options include aspirin as well as low-molecular-weight heparin. However, in women with heritable thrombophilia and unexplained recurrent pregnancy loss, evidence is not available as published trials have not used an adequate comparator (no treatment or placebo). Currently, randomized controlled trials with no treatment or placebo are being carried out and results should be awaited before implementing a potentially harmful intervention in pregnant women with heritable thrombophilia and a history of pregnancy failure. Both infertility and pregnancy failure are extremely distressing for couples with the desire to have children. Pregnancy failure comprises (recurrent) early miscarriage, as well as late pregnancy loss. The role of heritable thrombophilia in pregnancy failure is reviewed, with a focus on recurrent miscarriage, in terms of epidemiology, etiology, and potential therapeutic implications.

Abstract
A thorough review of the literature and of personal files has allowed the gathering of 81 patients with rare congenital bleeding disorders and thrombotic phenomena. Sixteen of these patients had congenital afibrinogenemia, eight involved factor V deficiency, 20 factor VII defects, 33 factor XI deficiencies and only one, a factor XIII defect. Altogether 42 patients showed arterial thrombosis (myocardial infarction [MI] in 28 cases; ischemic stroke in 4; arterial occlusion in 8; 2 patients with disseminated intravascular coagulation (DIC)). Ages varied between 13 and 74. Twenty-two patients were males and 16 females. In four cases, sex was not reported. There were three fatalities: two after a MI and one because of heart failure. With regard to venous thrombosis: 9 patients had pulmonary embolism, 15 patients had deep vein thrombosis, 9 patients had both pulmonary embolism and deep vein thrombosis; 1 patient had superficial vein thrombosis, whereas, 5 cases had an unusual site venous thrombosis (two portal systems, two cerebral sinuses, one inferior vena cava) for a total of 39 cases. Age varied between 3 and 86. In this case, 20 patients were males and 17 were females. In two cases, sex was not reported. There were three fatalities: two because of pulmonary embolism and one because of inferior vena cava thrombosis. The fact that thrombosis has never been described in patients with factor II or factor X seems to underscore the central antithrombotic role that these two factors have in the coagulation system.

Abstract
BACKGROUND Many patients with bleeding disorders have been infected with the hepatitis C virus (HCV), mainly with genotype 1. Antiviral treatment is only effective in 50% of these patients and is often accompanied by serious side effects. Consequently, careful selection of patients for treatment is warranted. Liver biopsies are generally not performed in these patients because of increased bleeding risk and high costs. We therefore assessed liver fibrosis and cirrhosis non-invasively using liver stiffness measurement (LSM). METHODS We enrolled 124 patients with bleeding disorders and chronic hepatitis C. Liver fibrosis was assessed by LSM using Fibroscan. In order to assess the validity of LSM in our hands, a separate group of 63 patients without bleeding disorders infected with HCV were evaluated with both LSM and biopsy. RESULTS In the validation study, liver elasticity was highly correlated with histological fibrosis stage (correlations coefficient 0.73, P < 0.001). Based on LSM, 18% of patients with bleeding disorders and chronic hepatitis C had severe fibrosis, and 17% had cirrhosis after 34 years of infection (range 14-40). However, the prevalence of cirrhosis based on laboratory and ultrasonographic findings was only 7%. Independent risk factors for an increase in LSM were older age at infection, higher body mass index, presence of viral co-infection, and male gender. Fifteen out of 59 patients (25%) with an apparent indication for treatment (significant fibrosis by LSM) agreed to start antiviral therapy within 3 months. CONCLUSIONS We found an unexpected high number of patients with significant fibrosis and cirrhosis in patients with bleeding disorders and hepatitis C detected by LSM, with considerable impact on the management of the disease.

Abstract
We describe a series of patients with combined factor deficiencies and von Willebrand's disease (VWD) at one haemophilia treatment centre. Although the incidence of VWD is at least 1% in the general population, combined coagulation defects have been infrequently described in the medical literature and are likely under diagnosed. This entity should be considered in patients with a known factor deficiency and either an unexpectedly severe bleeding phenotype, or bleeding that is unresponsive to factor replacement.

Abstract
The prevalence of concurrent multitypic hepatitis C virus (HCV) infection is uncertain. A sensitive and specific approach to identifying minority HCV genotypes in blood is presented. Following serum extraction and reverse transcription PCR to amplify cDNA originating from the viral 5' noncoding region, the amplified product mixture was treated with genotype-specific restriction endonuclease to digest the dominant genotype. Residual amplicons were subjected to PCR cloning and then to real-time DNA sequencing using a Pyrosequencer to identify the remaining genotypes. Dilution experiments showed that minority genotypes may be detected when they represent 1:10,000 of the total population and in serum specimens with viral loads as low as 1,000 IU/ml. Of 37 patients with bleeding disorders and 44 injecting drug users, infection by more than one HCV genotype was found in 7 (19%) and 4 (9%) patients, respectively. The low rate of detection in people at high risk of repeated HCV infection suggests that multitypic HCV carriage is uncommon.

Abstract
Venous thromboembolism (VTE) susceptibility genes are widely diffuse in the general population, but clinical penetrance of genotypes is incomplete and has variable expressivity. Therefore, the indiscriminate search for carriers is of doubtful utility and potentially detrimental for screened individuals. A targeted screening in kindreds in which VTE already occurred can be more fruitful in identifying individuals sharing with the proband one or more known susceptibility genes (possibly cosegregating with other ones still unknown). Clinical penetrance is variable, and is higher in the relatively rare deficiencies of antithrombin (AT), protein C (PC), or protein S (PS), and lower in the presence of the common polymorphisms factor V Leiden and prothrombin G20210A. Women with inherited thrombophilia should be warned about the thrombotic risk associated with the use of oral contraceptives or hormonal replacement treatment. Moreover, prophylaxis during puerperium and surgery or after trauma is warranted. The absolute risk associated with such situations is low but not negligible in the presence of deficiencies of AT, PC, or PS, homozygous conditions, and carriership of multiple defects. In such cases primary prophylaxis should be applied also during pregnancy and in general should be more stringent; moreover, in these patients the option for indefinite duration of secondary anticoagulant prophylaxis after VTE should be considered because of the relevant risk of recurrent VTE. In all cases, a careful balance of benefits and risks associated with prophylactic measures should be achieved, and patient preferences should be considered.

Abstract
The gynaecological and obstetric management of women with inherited coagulation disorders requires close collaboration between obstetrician/gynaecologists and haematologists. Ideally these women should be managed in a joint disciplinary clinic where expertise and facilities are available to provide comprehensive assessment of the bleeding disorder and a combined plan of management. The haematologist should arrange and interpret laboratory tests and make provision for appropriate replacement therapy. These guidelines have been provided for healthcare professionals for information and guidance and it is also intended that they are readily available for women with bleeding disorders.

Abstract
BACKGROUND Renal venous thrombosis (RVT) is the most common form of venous thrombosis in neonates, causing both acute and long term kidney dysfunction. Historical predisposing factors include dehydration, maternal diabetes, and umbilical catheters, but recent reports highlight associations with prothrombotic abnormalities. STUDY Twenty three patients with neonatal RVT were analysed over 15 years. Predisposing factors, presentation, and procoagulant status were compared with renal outcome using multilevel modelling. RESULTS Median presentation was on day 1: 19/23 (83%) had pre/perinatal problems, including fetal distress (14), intrauterine growth retardation (five), and pre-identified renal abnormalities (two); 8/18 (44%) had procoagulant abnormalities, particularly factor V Leiden mutations (4/18). Long term abnormalities were detected in 28/34 (82%) affected kidneys; mean glomerular filtration rate was 93.6 versus 70.2 ml/min/1.73 m2 in unilateral versus bilateral cases (difference 23.4; 95% confidence interval 6.4 to 40.4; p = 0.01). No correlation was observed between procoagulant tendencies and outcome, but presenting renal length had a significant negative correlation: mean fall in estimated single kidney glomerular filtration rate was 3 ml/min/1.73 m2 (95% confidence interval 3.7 to -2.2; p = 0.001) per 1 mm increase, and kidneys larger than 6 cm at presentation never had a normal outcome. CONCLUSIONS This subgroup of neonatal RVT would be better termed perinatal RVT to reflect antenatal and birth related antecedents. Prothrombotic defects should be considered in all patients with perinatal RVT. Kidney length at presentation correlated negatively with renal outcome. The latter, novel observation raises the question of whether larger organs should be treated more aggressively in future.

Abstract
Liver biopsy remains the gold standard for the evaluation of fibrosis despite its risks and limitations, especially in haemophilia patients. Recently, non-invasive biomarkers have been used to assess histological features. The most thoroughly evaluated biomarker is the FibroTest (FT) (AUROC 0.80 for fibrosis stages F2F3F4 vs. F0F1). To estimate liver fibrosis in haemophilia patients infected with hepatitis C (HCV) using non-invasive biomarkers without liver biopsy. One hundred and thirty-two haemophilia patients (124 male, mean age 38 +/- 14 years) with anti-HCV antibodies were evaluated. These patients were stratified into several groups: patients with features of advanced liver disease - seven, persistently HCV RNA-negative - 21, persistently normal liver function tests (LFTs)- 24, HCV/HIV co-infected - 27. The following biomarkers of fibrosis were used: FT, AST-to-platelet ratio index (APRI), Forns index, age-platelet index and hyaluronic acid. The obtained scores were correlated with the clinical features of the patients. Estimated by the FT, the distribution of the stage of fibrosis in the 132 patients was F0F1 = 65% (86/132), F2 = 5% (7/132), F3 = 13% (17/132) and F4 = 17% (22/132). Using FT, all patients with clinical suspicion of advanced liver disease were classified as F3F4, whereas patients with persistently HCV RNA-negative were all classified as F0F1. Twenty-one per cent (5/24) of the patients with persistently normal LFTs had fibrosis stage F3F4. The proportion of F3F4 among HCV/HIV co-infected patients was significantly higher than among HCV mono-infected (52% vs. 33%; P = 0.05). Concordance of three or more biomarkers was present in 43% (57/132) of the patients. Liver biopsy could be avoided in 70% (92/132) using a practical assumption that if FT is in concordance with APRI and/or Forns, then we may confidently rely on the biomarker. Concordance rate for patients with presumably advanced or minimal liver disease was excellent (100% and 95% respectively). In our HCV-infected haemophilia patients, FT correctly identified clinically advanced or minimal liver disease. Discordance among the various biomarkers of fibrosis was considerate; nevertheless, practical combination of FT, APRI, and Forns may predict stage of fibrosis with accuracy, potentially avoiding liver biopsy in the majority of the patients.

Abstract
We investigated the molecular mechanisms responsible for type I congenital antithrombin (AT) deficiency in two unrelated Chinese pedigrees manifesting multiple site venous thrombosis. Phenotype analysis showed both probands had almost 50% of normal AT levels. Direct sequencing of amplified DNA revealed 2757C > T in proband 1 and 13328G > A in proband 2, predicting a heterozygous Thr98Ile (T981) and Ala404Thr (A404T), respectively. No proband had 20210A allele or factor V Leiden mutation. Transient expression of complementary DNA coding for the mutations in COS-7 cells showed impaired secretion of the mutant molecules. Real-time quantitative PCR indicated that the mutant AT mRNA was transcribed at a similar or even higher level as that of wild-type (wt). Pulse-chase labeling studies suggested both AT variants did not accumulate, but degraded intracellularly. Immunohistochemical staining of the transfected cells revealed that CHO cells expressing the AT-198 mutant were stained diffusely without perinuclear enhancement and cells expressing AT-T404 mutant mainly in the whole cytoplasm with weaker perinuclear enhancement. We conclude that the impaired secretion of the mutant AT molecules, due to intracellular degradation, is the molecular pathogenesis of AT deficiency caused by T981 and A404T mutation for the two families, respectively.

Abstract
OBJECTIVE The purpose of this study was to examine whether women with inherited thrombophilia have an increased risk of developing pregnancy complications. METHODS All singleton pregnancies with known inherited thrombophilia were compared to those without inherited thrombophilia for deliveries during the years 2000-2002 in a tertiary medical center. Data regarding inherited thrombophilia (International Classification of Disease 9th revision, Clinical Modification code 286.3) were available from the perinatal database in our center. Women lacking prenatal care were excluded from the analysis. Stratified analysis, using a multiple logistic regression model, was performed to control for confounders. RESULTS Out of 32,763 singleton deliveries that occurred during the study period, 0.2% (n=57) of the women were diagnosed with inherited thrombophilia. Using a multivariate analysis, with backward elimination, the following conditions were significantly associated with inherited thrombophilia: previous fetal losses [odds ratio (OR)=5.5; 95% confidence interval (CI) 2.9-10.3; P<0.001], recurrent abortions (OR=9.5; 95% CI 5.5-16.3; P<0.001), fertility treatments (OR=3.7; 95% CI 1.3-10.6; P=0.014), and intrauterine growth restriction (OR=7.2; 95% CI 3.4-15; P<0.001). Perinatal mortality was significantly higher in women with inherited thrombophilia than in those without known thrombophilia 5.3% (3/57) versus 0.6% (477/32,763) P=0.017. However, inherited thrombophilia was not found to be an independent risk factor for perinatal mortality (OR=3.05; 95% CI 0.90-10.3; P<0.073) in a multivariate analysis with perinatal mortality as the outcome variable, controlling for recurrent abortions, IUGR, and gestational age. CONCLUSION Inherited thrombophilia, associated with previous fetal losses, recurrent abortions, fertility treatments, and intrauterine growth restriction, was not an independent risk factor for perinatal mortality.

Abstract
AbstractThe clinical management of individuals with hereditary hypercoaguable disorders has evolved from initial broad recommendations of lifelong anticoagulation after first event of venous thromboembolism to a more intricate individualized risk-benefit analysis as studies have begun to delineate the complexity of interactions of acquired and hereditary factors which determine the predilection to thrombosis. The contribution of thrombophilic disorders to risk of thrombotic complications of pregnancy, organ transplantation, central venous catheter and dialysis access placement have been increasingly recognized. The risk of thrombosis must be weighed against risk of long-term anticoagulation in patients with venous thromboembolism. Thrombophilia screening in select populations may enhance outcome.

Abstract
The Budd-Chiari syndrome (BCS), characterized by the obstruction and occlusion of the suprahepatic veins, is a rare but typical complication occurring in patients with polycythemia vera (PV). We describe three young women who developed BCS as first manifestation of PV, in association with an inherited thrombophilic state and in the absence of concomitant use of oral contraceptives. Our report illustrates the existence of an aggressive form of myeloproliferative disorder, which requires prompt recognition and immediate therapeutic intervention including cytostatic drugs and anticoagulant treatment. Furthermore, we suggest the need of routine screening for thrombophilic state in young women affected by PV.

Abstract
Stroke is an uncommon but increasingly recognised cause of mortality and long-term neurological morbidity in children. A significant number of these events appear to be caused by thromboembolic disease and, as with other childhood thrombotic problems, the incidence of central nervous system events appears highest during the neonatal period. In contrast to peripheral arterial and venous thrombotic problems, it is likely that a proportion of cerebral thromboembolic events occur either in utero or perinatally and reflect different risk factors from those occurring in older infants and children. The pathophysiology of perinatal stroke is complex and in many cases is likely to be multifactorial. It is now recognised that risk factors may relate to both maternal and placental problems as well as fetal and neonatal disorders. Large prospective studies of perinatal stroke are currently lacking and efforts to define the relative contribution from each of these areas are at an early stage. The complex nature of these disorders requires collaboration between a number of different disciplines including obstetrics, fetal medicine, pathology, neonatology and neurology. Of particular interest to haematologists is the possible impact of prothrombotic abnormalities in the pathophysiology of these events and also the potential for the use of antithrombotic agents in both management and prevention.

Abstract
Prior to the introduction of virally inactivated clotting factor concentrates, the majority of individuals with congenital bleeding disorders became infected with the hepatitis C virus. Although liver biopsy is valuable in prognosis and guiding antiviral therapy, there is a reluctance to perform biopsies in this population because of the risk of hemorrhage. The purpose of this study was to evaluate the safety of transjugular liver biopsy, and the usefulness of evaluating liver histology in this patient population. Liver histopathology was assessed by the METAVIR index and compared with corrected sinusoidal pressures, platelet counts, and abdominal ultrasonography. Liver biopsy was performed at seven Canadian centers in 65 patients with hemophilia or von Willebrand's disease. Biopsies were done on an outpatient basis, followed by a 4-hr observation period in hospital. Normal hemostasis was maintained during the peribiopsy period, with follow-up doses of factor concentrate self administered by the patient at home. One patient (1.4%) had significant bleeding leading to readmission and red cell transfusion. Liver histology showed 14 patients (22%) had cirrhosis. Ten patients had elevated corrected sinusoidal pressures; 7 of these (70%) had cirrhosis on biopsy, and the other 3 (30%) likely had cirrhosis although histology showed stage 3 fibrosis. This series represents the largest reported experience of transjugular biopsy in individuals with congenital bleeding disorders. We conclude that this procedure can be safely performed on an outpatient basis. The diagnosis of cirrhosis and/or portal hypertension was made in a substantial proportion of individuals (26%), all of whom had asymptomatic liver disease.
