Applicability of the European Society of Cardiology guidelines on management of acute coronary syndromes to people with haemophilia - an assessment by the ADVANCE Working Group

There are no evidence‐based guidelines for antithrombotic management in people with haemophilia (PWH) presenting with acute coronary syndrome (ACS). The aim of the study was to review the current European Society of Cardiology guidelines, and to consider how best they should be adapted for PWH. Structured communication techniques based on a Delphi‐like methodology were used to achieve expert consensus on key aspects of clinical management. The main final statements are as follows: (i) ACS and myocardial revascularization should be managed promptly by a multidisciplinary team that includes a haemophilia expert, (ii) each comprehensive care centre for adult PWH should have a formal clinical referral pathway with a cardiology centre with an emergency unit and 24 h availability of percutaneous coronary intervention (PCI), (iii) PCI should be performed as soon as possible under adequate clotting factor protection, (iv) bare metal stents are preferred to drug‐eluting stents, (v) anticoagulants should only be used in PWH after replacement therapy, (vi) minimum trough levels should not fall below 5–15% in PWH on dual antiplatelet therapy, (vii) the duration of dual antiplatelet therapy after ACS and PCI should be limited to a minimum, (viii) the use of GPIIb‐IIIa inhibitors is not recommended in PWH other than in exceptional circumstances, (ix) the use of fibrinolysis may be justified in PWH when primary PCI (within 90 min) is not available ideally under adequate clotting factor management. It is hoped that the results of this initiative will help to guide optimal management of ACS in PWH

Hypertension, haematuria and renal functioning in haemophilia - a cross-sectional study in Europe.

BACKGROUND AND OBJECTIVES: This cross-sectional, epidemiological study sought to assess the prevalence and extent of potential risk factors for hypertension, particularly renal function related to haematuria and their associations in people with haemophilia. METHODOLOGY: Demographic and medical data were collected at a single time-point in patients with haemophilia over 40 years of age from 16 European centres. Associations with diagnosis of hypertension were tested in univariate and multivariate analyses. RESULTS: We enrolled 532 patients (median age 52 years, range 40-98) with haemophilia A (n = 467) or haemophilia B (n = 65). Haemophilia was severe (30 kg m-2 ). Estimated glomerular filtration rate (eGFR) 2.8 were diabetes (OR = 2.8, P = 0.04), coronary artery disease (OR = 3.3, P = 0.052) and family history of hypertension (OR = 4.4, P < 0.001). Neither severity of haemophilia nor history of haematuria was significantly associated with hypertension in univariate or multivariate analyses. CONCLUSION: As in the general population, age and BMI were major risk factors for hypertension in people with haemophilia. Renal dysfunction was associated with hypertension, but the prevalence of renal dysfunction was not extensive and furthermore not significantly correlated with haematuria. The associations of other variables with hypertension require further studies to confirm causal relationships over time

The elevated prevalence of risk factors for chronic liver disease among ageing people with hemophilia and implications for treatment

Chronic liver disease (CLD) is frequently seen in the hemophilia population. The ADVANCE Working Group conducted a cross-sectional study in which people with hemophilia (PWH) aged ≥40 years were included. This study aimed to assess the associations between CLD and its risk factors using data from the H3 study, and to suggest implications for optimal care.Data from 13 European countries were collected at a single time-point (2011-2013). Univariate and multivariate logistic regression (MLR) analyses were performed.A total of 532 PWH were included with either hemophilia A (n = 467) or hemophilia B (n = 65). A total of 127 (24%) were diagnosed with CLD. Hepatitis C virus (HCV), human immunodeficiency virus (HIV), total cholesterol, and severe hemophilia were significant risk factors in univariate logistic regressions. In MLR, HCV Ab+/PCR+ (OR = 17.6, P < .001), diabetes (OR = 3.0, P = .02), and HIV (OR = 1.9, P = .049) were positively associated with CLD. Total cholesterol (OR = 0.6, P = .002) was negatively associated with CLD. We found no evidence of interaction effects among the explanatory variables. No significant associations with age and type of or severity of hemophilia were observed in MLR.The main risk factors for CLD in this European cohort also apply to the general population, but the prevalence of HCV and HIV is considerably larger in this cohort. With new and improved treatment options, intensified eradication therapy for HCV seems justified to prevent CLD. Similarly, intensified monitoring and treatment of diabetes seem warranted
