RESUMO

Hemophilia is a congenital bleeding disorder caused by low levels of clotting factor VIII or IX. The life expectancy of people with hemophilia (PWH) has increased with the availability of clotting factor concentrates. At the same time, the incidence of cardiovascular disease (CVD) has increased; in retrospective studies, there are conflicting data regarding if, despite this increase, the incidence is still lower than in the general population. We prospectively compared the incidence of CVD in PWH vs the predicted incidence. This prospective, multicenter, observational study included adult PWH (aged >30 years) from The Netherlands and United Kingdom. They were followed up for a 5-year period, and CVD incidence was compared with a predicted event rate based on the QRISK2-2011 CVD risk model. The primary end point was the observed fatal and nonfatal CVD incidence after 5 years compared with the estimated events and in relation to severity of hemophilia. The study included 709 patients, of whom 687 (96.9%) completed 5 years' follow-up or reached an end point. For 108 patients, the QRISK score could not be calculated at inclusion. For the remaining 579, fewer CVD events were observed than predicted: 9 vs 24 (relative risk, 0.38; 95% confidence interval, 0.18-0.80; P = .01), corresponding with an absolute risk reduction of 2.4%. Severe hemophilia treated on demand had the highest risk reduction. There was no statistically significant relation between severity of hemophilia and incidence of CVD. In hemophilia, a lower-than-predicted CVD incidence was found, supporting the theory that hemophilia protects against CVD. The study is registered at www.clinicaltrials.gov as #NCT01303900.

RESUMO

INTRODUCTION: Persons with hemophilia and hepatitis C virus (HCV) infection have a lower health-related quality of life (HRQoL) than those never HCV infected. However, it is unknown whether HRQoL after HCV eradication is comparable to individuals never HCV infected. We aimed to compare HRQoL between HCV-cured and never chronically HCV-infected persons with hemophilia. METHODS: All persons with hemophilia in the Netherlands were invited for a nationwide study conducted in 2018-2019. For the current analysis, participants born before 1992 with data on HRQoL and HCV status were included. HCV status was collected from medical records. HRQoL was measured by RAND-36 questionnaire, with a minimally important difference set at 4.0 points. Multivariable linear regression was used to adjust for age, hemophilia severity, HIV status, and self-reported joint impairment. RESULTS: In total, 486 persons were eligible; 180 were HCV cured and 306 never chronically HCV infected. Compared with those never HCV infected, HCV-cured individuals were older (57 vs. 53 years), more often had severe hemophilia (67% vs. 21%), and reported more impaired joints (median 3 vs. 0). Compared with those never HCV infected, adjusted RAND-36 domain scores of HCV-cured individuals cured were lower on all RAND-36 domains except Pain, ranging from a difference of 4.5 (95% CI, -8.8 to -0.3) for Physical functioning to 11.3 (95% CI, -19.4 to -3.1) for Role limitations due to physical problems. CONCLUSION: Despite effective HCV treatment, HRQoL of HCV-cured persons with hemophilia is still lower than HRQoL of those never chronically HCV-infected on all RAND-36 domains. This implies that careful psychosocial follow-up and support are indicated.

RESUMO

INTRODUCTION: Despite increasing awareness of issues faced by women and girls with inherited BDs (WGBD), standards of care are lacking, with disparities in diagnosis and treatment for WGBD across Europe. We aimed to develop practical principles of care (PoC) to promote standardization of care for WGBD within European Haemophilia Treatment and Comprehensive Care Centres (HTC/CCCs). METHODS: The co-creation process, supported by the European Association for Haemophilia and Allied Disorders, consisted of four multidisciplinary meetings with health care providers (HCPs) experienced in WGBD care, and European Haemophilia Consortium representatives, combined with broad patient and HCP consultations in the European haemophilia community. Relevant medical societies outside Europe were contacted for confirmation. RESULTS: We developed ten PoC for WGBD, stressing the importance and benefits of a centralized, multidisciplinary, comprehensive, family-centred approach to support and manage WGBD during all life stages. These PoC emphasise the right to equitable access and quality of care for all people with BDs, irrespective of gender. Multiple medical societies outside Europe also confirmed their support for endorsement. CONCLUSIONS: Ten PoC for WGBD evolved from an iterative process among stakeholders, supported by relevant medical societies worldwide. These PoC can serve as a benchmark for diagnosis and comprehensive multidisciplinary management of WGBD, and improve awareness of their unique challenges. They offer a framework to guide HTC/CCCs in providing equitable care for all WGBD, both in their own services and in other healthcare settings. Implementation of these principles aims to positively impact the health, wellbeing and quality of life for WGBD.

RESUMO

INTRODUCTION: Multidisciplinary management of women-specific bleeding is important to preserve quality of life, healthy reproduction and social participation of women and girls with bleeding disorders (WBD). AIM: To support appropriate multidisciplinary care for WBD in haemophilia treatment centres. METHODS: Two case examples are presented and management issues discussed from different health care perspectives, including the nurse, patient, psychologist, gynaecologist, geneticist, psychosexual therapist and haematologist. RESULTS: Woman with bleeding disorders may experience heavy menstruation from menarche onwards. This has a physical and psychosocial impact requiring a multidisciplinary approach. If a woman with an inherited bleeding disorder desires to become pregnant, preconception counselling is essential, to discuss genetic diagnosis, state of the art treatment options for the bleeding disorder in question and possible choices to prevent having an affected child, as well as maternal bleeding risks during conception, delivery and the post-partum period. CONCLUSION: Adequate management and good education of WBD requires a patient-centred multidisciplinary approach with experienced specialists in a haemophilia treatment centre.

RESUMO

INTRODUCTION: The impact of bleeding for women with bleeding disorders (WBD) is of increasing focus and importance. Despite this, optimal management strategies are unclear and knowledge gaps persist. AIM: To examine practices and define research priorities on diagnosis and management of WBD in Europe. METHODS: An electronic survey on clinical management of WBD was sent to 136 European haemophilia treatment centres (HTCs), including open questions on knowledge gaps and research priorities. RESULTS: Fifty-nine HTCs from 12 Western (WE) and 13 Central/Eastern European (CEE) countries completed the survey. Less than half runs a joint clinic (24 HTCs, 42%). Most centres without a joint clinic have a named obstetrician (81%) and/or gynaecologist (75%) available for collaboration. Overall 18/54 (33%) European HTCs do not offer preimplantation genetic diagnosis. Third trimester amniocentesis to guide obstetric management is available 28/54 HTCs (52%), less frequent in CEE compared to WE countries (5/17 vs 23/37, P = .03). 53% of HTCs (28/53) reported that only 0%-25% of WBD seek medical advice for heavy menstrual bleeding (HMB). An algorithm managing acute HMB in WBD is lacking in 22/53 (42%) HTCs. The main reported knowledge and research gaps are lack of awareness & education on WBD among patients and caregivers, optimal diagnostic strategies and effective multidisciplinary management of pregnancy & HMB. CONCLUSION: Joint clinics, prenatal diagnostics and algorithms for managing acute HMB are lacking in many European HTCs. HMB may be an underestimated issue. This survey highlights the need to prioritize improvement of knowledge and patient care for WBD across Europe.

RESUMO

Background Management of atrial fibrillation (AF) is complex in patients with bleeding disorders. Catheter ablation such as pulmonary vein isolation (PVI) has been suggested in cases with bleeding disorders. However, data on safety are missing. This report describes the outcome of PVI in patients with bleeding disorders. Methods A retrospective study in our hemophilia treatment center of patients who underwent a PVI in 2014 to 2018. PVI was done according to local protocol. Clotting factor was given periprocedural. Postprocedural anticoagulation was given for at least 4 weeks, with clotting factor suppletion if needed to maintain factor VIII (FVIII) levels >0.20 IU/mL. Results and Discussion Five patients with hemophilia and one with von Willebrand disease were included. Eight PVIs were performed. Target FVIII levels (>0.80 IU/mL) were met before the procedure. Postprocedural anticoagulation was given: vitamin K antagonist (VKA) or direct oral anticoagulant (DOAC) dabigatran. All patients obtained long-term sinus rhythm, in two patients after a second PVI. However, late recurrent AF occurred in one patient after 42 months. A notable incidence of groin bleeds was observed: two of eight interventions (25%) compared with 0.9% in the general population. Bleeding seemed to be related to agitation, early mobilization, and bridging of VKA with low molecular weight heparin (LMWH). No relevant bleeding was observed when on DOAC therapy. Conclusion PVI seems to be effective in the case of bleeding disorders. To reduce the groin bleeds agitation and early mobilization should be avoided and DOAC is preferred over bridging VKA with LMWH.

RESUMO

INTRODUCTION: Patients with bleeding disorders may experience limitations in sports participation and physical activity. Several studies on sports participation have been performed in haemophilia patients, but studies in patients with von Willebrand disease (VWD) are lacking. AIM: We assessed the sports participation and physical activity of a large cohort of VWD patients. METHODS: Patients were included from the "WiN study." All patients completed a questionnaire on sports participation, physical activity, quality of life and bleeding symptoms (Tosetto bleeding score). RESULTS: From the 798 included patients, 474 had type 1, 301 type 2 and 23 type 3 VWD. The mean age was 39 ± 20 (standard deviation) years. Five hundred and fifty-two patients (69.3%) participated in various types of sports. Type 3 VWD patients more often did not participate in sports due to fear of bleeding and physical impairment, respectively, OR = 13.24 (95% CI: 2.45-71.53) and OR = 5.90 (95% CI: 1.77-19.72). Patients who did not participate in sports due to physical impairment had a higher bleeding score item for joint bleeds 1.0 (±1.6) vs 0.5 (± 1.1) (P = 0.036). Patients with type 3 VWD and patients with a higher bleeding score frequently had severe limitations during daily activities, respectively, OR = 9.84 (95% CI: 2.83-34.24) and OR = 1.08 (95% CI: 1.04-1.12). CONCLUSION: The majority of VWD patients participated in sports. Patients with type 3 VWD, a history of joint bleeds and a more severe bleeding phenotype frequently experienced limitations in sports participation and physical activities during daily life.

RESUMO

Long-term outcome after joint bleeds in von Willebrand disease (VWD) (von Willebrand factor activity ≤ 30 IU/dL) could differ from moderate or severe haemophilia A (HA) (factor VIII [FVIII] 1-5 IU/dL or FVIII < 1 IU/dL). We performed a post hoc analysis on Haemophilia Joint Health Score (HJHS, 0-124), X-ray Pettersson scores (PS, 0-13/joint) and the Haemophilia Activities List (HAL, 0-100), using multivariable regression to adjust for age (rate ratio [RR] or odds ratio [OR] [95% confidence interval]). We included 48 VWD (median age, 47 years, type 3 VWD, n = 19), 39 moderate HA (median, 39 years) and 59 severe HA patients (median, 25 years) with documented joint bleeds. VWD patients suffered repeated bleeding (lifetime > 5/joint) less often than moderate and severe HA patients (52% vs. 77% vs. 98%). HJHS and PS in VWD were similar to moderate HA (median HJHS 5 vs. 6, RR 0.9 [0.5-1.4] and PS > 3 of ≥ 1 joint OR 0.3 [0.1-1.4]), but better than in severe HA patients (median HJHS 5 vs. 9, RR 1.8 [1.1-2.9]; PS > 3 in any joint OR 0.1 [0.0-0.3]). Self-reported limitations in activities were comparable across VWD, moderate HA (HAL score < 95: 67% vs. 49%; OR 1.4 [0.5-3.6]) and young adults with severe HA (67% vs. 48%; OR 1.7 [0.7-4.4]). Despite fewer joint bleeds, joint outcome after joint bleeds was similar in VWD and moderate HA patients. Type 3 VWD patients had worst joint outcome, comparable to younger intensively treated severe HA patients. Limitations in activities occurred as often in VWD as in both moderate and severe HA.

RESUMO

INTRODUCTION: Pegylated interferon-based therapy for hepatitis C virus (HCV) negatively impacts nutritional state and patient-reported outcomes (PROs) such as health-related quality of life (HRQL). Clinical trials with direct-acting antivirals (DAAs) report significant PRO improvement but real-world data are still scarce. METHODS: Prospective cohort study recruiting HCV patients treated with DAAs in 2015-2016. Data at baseline, end of treatment (EOT) and 12 weeks thereafter (FU12) included: patient-reported medication adherence; SF-36; Karnofsky Performance Status; paid labour productivity; physical exercise level; nutritional state [by body mass index (BMI) and Jamar hand grip strength (HGS)] and Beliefs about Medicines Questionnaire. Potential factors predicting these PROs were evaluated with multiple regression analysis. RESULTS: A total of 68 patients were enrolled: 85% male, median age 57 years, 80% genotype 1, 40% cirrhotics, 46% haemophilia. Both cure rate and patient-reported adherence were 97%. SF-36 Physical Component Summary did not change (43.2 ± 11.9, 44.9 ± 10.3 and 44.7 ± 10.9 at baseline, EOT and FU12, p = 0.71). In contrast, SF-36 mental component summary (MCS) decreased transiently during therapy (49.2 ± 11.9, 44.6 ± 10.3 and 49.9 ± 12.6 at baseline, EOT and FU12, p < 0.01). Concomitant ribavirin-use was the only independent predictor of decreased SF-36 MCS. BMI (25.7 ± 4.5 and 25.6 ± 4.4 at baseline and EOT, p = 0.8) and Jamar HGS (39.7 ± 13.0, 37.4 ± 11.9 and 37.9 ± 13.8 at baseline, EOT and FU12, p = 0.56) did not change. CONCLUSION: Our study reveals concomitant ribavirin as the only independent predictor of transient decrease in SF-36 mental HRQL during DAA therapy. In contrast to interferon-based therapy, DAAs do not affect BMI or Jamar HGS.

RESUMO

Some comorbidities, such as hypertension, are associated with higher von Willebrand factor (VWF) levels in the general population. No studies have been conducted to assess this association in patients with von Willebrand disease (VWD). Therefore, we studied this association in patients with type 1 (n = 333) and type 2 (n = 203) VWD from the 'WiN" study. VWF antigen (VWF:Ag) was higher in type 1 VWD patients with hypertension [difference: 0·23 iu/ml, 95% confidence interval (CI): 0·11-0·35], diabetes mellitus (0·11 iu/ml, 95% CI: -0·02 to 0·23), cancer (0·14 iu/ml, 95% CI: 0·03-0·25) and thyroid dysfunction (0·14 iu/ml, 95% CI: 0·03-0·26) than in patients without these comorbidities (all corrected for age, sex and blood group). Similar results were observed for VWF collagen binding capacity (VWF:CB), VWF activity as measured by the VWF monoclonal antibody assay (VWF:Ab) and factor VIII (FVIII) coagulant activity (FVIII:C). In type 1 VWD, age was associated with higher VWF:Ag (0·03 iu/ml; 95% CI: 0·01-0·04), VWF:CB (0·02 iu/ml; 95% CI: 0·00-0·04), VWF:Ab (0·04 iu/ml; 95% CI: 0·02-0·06) and FVIII:C (0·03 iu/ml; 95% CI: 0·01-0·06) per decade increase. After adjustment for relevant comorbidities, these associations were no longer significant. Despite the higher VWF and FVIII levels, type 1 VWD patients with comorbidities had more bleeding episodes, particularly during surgery. There was no association between comorbidities and VWF/FVIII levels or bleeding phenotype in type 2 VWD patients. In conclusion, comorbidities are associated with higher VWF and FVIII levels in type 1 VWD and may explain the age-related increase of VWF and FVIII levels.

RESUMO

Patients with severe von Willebrand disease (VWD) may develop arthropathy after joint bleeds. Information on its prevalence and severity is limited. We aimed to assess the occurrence and severity of arthropathy in VWD and its impact on daily life. VWD patients with and without verified joint bleeds were matched for age, sex and Factor VIII level or von Willebrand Factor activity in a nested case-control study within the Willebrand in the Netherlands study. Assessments included the Hemophilia Joint Health Score (0-124), Pettersson score (0-13 per joint X-ray), Hemophilia Activity List score (0-100), joint pain (Visual Analog Scale 0-10), and the Impact on Participation and Autonomy questionnaire (0-20). Arthropathy was defined as a Hemophilia Joint Health Score of 10 or higher, or a Pettersson score over 3 of at least one joint. We included 48 patients with verified joint bleeds (cases) and 48 controls: 60% males, mean age 46 years (range 18-80), median von Willebrand Factor activity 5 versus 8 IU/dL and Factor VIII 24 versus 36 IU/dL. Arthropathy occurred in 40% of the cases versus 10% of the controls (P<0.01). The cases reported more functional limitations compared to the controls (median Hemophilia Activity List score: 88 vs. 100, P<0.01). Arthropathy was related to joint pain and less social participation (Visual Analog Scale>3: 13 of 19 vs. 3 of 28, P<0.01, and median score on the participation questionnaire 6.1 vs. 0.9, P<0.01). In conclusion, arthropathy occurs in 40% of VWD patients after joint bleeds and is associated with pain, radiological abnormalities, functional limitations, and less social participation (Dutch trial register: NTR4548).

RESUMO

Assessment of clinical outcome after joint bleeding is essential to identify joint damage and optimise treatment, to prevent disability. However, disease-specific tools to assess the musculoskeletal status in patients with von Willebrand disease (VWD) are lacking. We aimed to determine validity and reliability of the Haemophilia Joint Health Score (HJHS) and Haemophilia Activities List (HAL) in patients with Von Willebrand disease (VWD). Ninety-six patients with VWD were included (mean age 46 years) of whom 27 had more than five documented joint bleeds. The HJHS was performed in all patients and all patients completed the HAL and Impact on Participation and Autonomy (IPA) questionnaires. Health-related quality of life (SF36) results were obtained from the prior 'Willebrand in the Netherlands' study. Joint X-rays of knees, elbows and ankles were scored according to Pettersson (PS). Internal consistency of the HJHS (Cronbach's α (α)=0.75) and HAL (α=0.89) were good. Inter-observer agreement of the HJHS was good (ICC 0.84; Limits of Agreement ± 10.3). The HJHS showed acceptable correlation with the X-ray PS (Spearman's r (rs)>0.60 all joints) and HAL (rs=0.71). The HAL also showed acceptable correlation with the SF36 physical functioning (rs=0.65) and IPA (rs=0.69). Hypothesis testing showed adequate discriminative power of both instruments: in patients with a history of >5 versus ≤ 5 joint bleeds (median HJHS 10 vs 2 (p<0.01); median HAL 77 vs 98 (p<0.01)), independent from age. In conclusion, both the HJHS and HAL are feasible to assess clinical outcome after joint bleeds in VWD.

RESUMO

The ratios between von Willebrand factor propeptide (VWFpp) or factor VIII activity ( FVIII: C) and VWF antigen (VWF:Ag) reflect synthesis, secretion, and clearance of VWF. We aimed to define the pathophysiology of 658 patients with type 1, 2, or 3 von Willebrand disease (VWD) with VWF levels ≤30 U/dL from the Willebrand in The Netherlands (WiN) study using the VWFpp/VWF:Ag and FVIII: C/VWF:Ag ratios. We evaluated the use of VWFpp in the classification and diagnosis of VWD. On the basis of the ratios, reduced VWF synthesis was observed in 18% of type 1 and only 2% of type 2 patients. A significant proportion of type 3 patients had detectable VWFpp (41%). These patients had a lower bleeding score than type 3 patients who had a complete absence of VWF:Ag and VWFpp (14.0 vs 19.5; P = .025). The majority of these patients had missense mutations with rapid VWF clearance, whereas type 3 patients with no VWFpp were homozygous for null alleles. In conclusion, VWFpp identified severe type 1 VWD with very low VWF levels in patients who had previously been classified as type 3 VWD. This study underlines the clinical significance of the VWFpp assay in the diagnosis and classification of VWD.

RESUMO

Clinically, the leading symptom in von Willebrand disease (VWD) is bleeding, chiefly of mucosal type, for example, epistaxis, gingival, or gastrointestinal bleeding, and menorrhagia. In severe forms of VWD with secondary deficiency of factor VIII, spontaneous joint bleeding, resembling that observed in severe haemophilia A, may also be observed. The bleeding patterns of VWD can affect quality of life, and may be life-threatening. The von Willebrand Disease Prophylaxis Network is an international study group formed with the goal of investigating the role of prophylaxis in clinically severe VWD. The objective of the present study is to investigate the response to prophylaxis focusing primarily on epistaxis, joint bleeding, gastrointestinal bleeding, and heavy bleeding associated with menses. Data from 105 subjects, 10 enrolled in a prospective study and 95 in a retrospective study between 2008 and 2013, were available for analysis. The median annualized rate reductions in bleeding were significant for epistaxis (P < 0.0001), gastrointestinal bleeding (P = 0.0003), joint bleeding (P < 0.0001), and menorrhagia (P = 0.008). Doses on a group level were approximately the same prior to and during prophylaxis, but more patients with gastrointestinal bleeding had prophylaxis three or more times per week as well as higher dosages. Our study, which primarily used retrospective data, indicates that prospective studies are needed to better delineate the doses and dose intervals that should be used for prophylactic treatment of VWD.

RESUMO

This multinational, randomized, single-blind trial investigated the safety and efficacy of nonacog beta pegol, a recombinant glycoPEGylated factor IX (FIX) with extended half-life, in 74 previously treated patients with hemophilia B (FIX activity ≤2 IU/dL). Patients received prophylaxis for 52 weeks, randomized to either 10 IU/kg or 40 IU/kg once weekly or to on-demand treatment of 28 weeks. No patients developed inhibitors, and no safety concerns were identified. Three hundred forty-five bleeding episodes were treated, with an estimated success rate of 92.2%. The median annualized bleeding rates (ABRs) were 1.04 in the 40 IU/kg prophylaxis group, 2.93 in the 10 IU/kg prophylaxis group, and 15.58 in the on-demand treatment group. In the 40 IU/kg group, 10 (66.7%) of 15 patients experienced no bleeding episodes into target joints compared with 1 (7.7%) of 13 patients in the 10 IU/kg group. Health-related quality of life (HR-QoL) assessed with the EuroQoL-5 Dimensions visual analog scale score improved from a median of 75 to 90 in the 40 IU/kg prophylaxis group. Nonacog beta pegol was well tolerated and efficacious for the treatment of bleeding episodes and was associated with low ABRs in patients receiving prophylaxis. Once-weekly prophylaxis with 40 IU/kg resolved target joint bleeds in 66.7% of the affected patients and improved HR-QoL. This trial was registered at www.clinicaltrials.gov as #NCT01333111.

RESUMO

BACKGROUND & AIMS: Patients with inherited bleeding disorders are an interesting group to study the long-term course of chronic hepatitis C virus (HCV) infection, because of their uniform mode of infection and reliable follow-up. Our aim was to assess the long-term occurrence of adverse liver-related events in these patients. METHODS: The occurrence and determinants of end-stage liver disease (ESLD) were assessed using retrospective data of 863 HCV infected patients with inherited bleeding disorders from the Netherlands and the UK. RESULTS: Median follow-up since HCV infection was 31 years, while 30% of patients had >35 follow-up years. Nineteen percent of patients spontaneously cleared the virus and 81% developed chronic HCV infection. Of the 700 patients with chronic HCV, 90 (13%) developed ESLD. Hepatocellular carcinoma (HCC) was diagnosed in 3% of patients with chronic HCV, 41% of which occurred in the last six years. Determinants of ESLD development were age at infection (hazard ratio (HR) 1.09 per year increase), HIV co-infection (HR 10.85), history of alcohol abuse (HR 4.34) and successful antiviral treatment (HR 0.14). Of the 487 patients who were still alive at the end of follow-up, 49% did not undergo optimal conventional antiviral treatment. CONCLUSIONS: After over 30 years of HCV infection, ESLD occurred in a significant proportion of patients with inherited bleeding disorders. HCC appears to be an increasing problem. There is a significant potential for both conventional and new antiviral treatment regimens to try and limit ESLD occurrence in the future.

RESUMO

Cardiovascular disease (CVD) mortality is reported to be decreased in haemophilia patients, but reports on the prevalence of CVD risk factors are conflicting. A cross-sectional assessment of CVD risk profiles was performed in a large cohort of haemophilia patients. Baseline data on CVD risk factors of 709 Dutch and UK haemophilia patients aged ≥30 years were analysed and compared with the general age-matched male population. CVD risk profiles were assessed using the QRISK®2-2011 and SCORE algorithms. Although QRISK® 2 was only validated in the UK, comparison with SCORE indicated similar properties of QRISK®2 in both Dutch and UK patients (correlation 0.86). Mean age was 49.8 years. Hypertension was more common in haemophilia patients than in the general population (49% vs. 40%), while the prevalences of obesity and hypercholesterolaemia were lower (15 vs. 20% and 44 vs. 68%, respectively), and those of diabetes and smoking were similar. The predicted 10-year QRISK®2 risk was significantly higher in haemophilia patients than in the general population (8.9 vs. 6.7%), indicating more unfavourable cardiovascular disease risk profiles. This increased risk became apparent after the age of 40 years. Our results indicate an increased prevalence of hypertension and overall more unfavourable CVD risk profiles in haemophilia patients compared with the general age-matched male population.
