Abstract
INTRODUCTION Cardiovascular diseases (CVD) that require long-term anticoagulant and antiplatelet therapy presents a problem in people with haemophilia (PWH) who receive factor replacement therapy to reduce bleeding risk. Currently, there are no Japanese guidelines for the management of PWH with CVD. AIM To develop expert guidance on managing CVD in PWH in Japan. METHODS A steering committee of four experts (two haemophilia specialists, one thrombosis specialist, one cardiologist) identified 44 statements related to five key themes. An online questionnaire was produced comprising a mix of 4-point Likert scale and multiple-choice questions that was sent to specialists in the management of PWH with CVD in Japan. Consensus was defined as high or very high if a respective ≥75% or ≥90% of respondents agreed with a statement. RESULTS Of 16 potential respondents, responses were received from 15 specialists. Of the Likert scale questions, 71% (29/41) achieved ≥90% agreement (very strong agreement), 17% (7/41) achieved 75%-89% agreement (strong agreement) and 15% (6/41) did not achieve consensus agreement. The three multiple-choice questions failed to identify a strong preference. Agreement on specific target trough clotting factor levels for managing certain clinical situations, such as when in the presence of non-valvular atrial fibrillation or myocardial infarction, was also achieved. CONCLUSION The results of this consensus study provide a framework for cardiologists and haematologists to manage PWH who are at risk of, or who have, CVD. Implementation of the recommendations provided herein may improve outcomes for PWH with CVD.

Abstract
Revolutionary advances in the treatment of hemophilia has led to a significant improvement in life expectancy. Associated with this has been an increase in age-related diseases especially atherosclerotic cardiovascular disease (CVD). While people with hemophilia (PWH) develop atherosclerosis at rates similar to those of the general population, rates of atherothrombosis and mortality related to CVD have been much lower, due to their hypocoagulable state. Changing treatment paradigms, aimed at reducing the risk of bleeding by improving hemostasis to levels approaching normality, has meant that the protection they are thought to have had may be lost. CVD risk factors are just as common in PWH as in the general population, but appear to be undertreated. In particular, primary prevention of CVD is vital in all individuals, but particularly in PWH as treatment of established CVD can be difficult. Active identification and management of CVD risk factors, such as obesity, physical inactivity, hypertension, and hypercholesterolemia, is required. In particular, statins have been shown to significantly reduce cardiovascular and all-cause mortality with few adverse events and no increased risk of bleeding in the general population, and their use needs urgent assessment in PWH. Further longitudinal research into preventing CVD in PWH, including accurate CVD risk assessment, is required to optimize prevention and management.

Abstract
As treatments for individuals with inherited bleeding disorders improve, life expectancy increases and is approaching that of the normal population. Concomitant with this we are now seeing the problems of ageing in the bleeding disorder population. Although the clear-cut association between low clotting factor levels and risk of bleeding is well recognised, a relationship between high levels, some non-factor therapies and thrombotic risk also exists. The management of thrombosis in persons with inherited bleeding disorders is complex but manageable with modern treatments and collaboration in decision making between health care professionals and patients. Despite the improvements in treatment and reduction in bleeding, mostly musculoskeletal pain continues to be a major issue with advancing age. The management of pain amongst older people with haemophilia who may have multiple comorbidities should involve a person-centred, holistic, multi-disciplinary approach to support and optimise long-term physical functioning and overall quality of life.

Rates of venous thromboembolism and use of thromboprophylaxis after major orthopedic surgery in patients with congenital hemophilia A or B: a systematic review. J Thromb Haemost 2024; 22:1117-1131.

Abstract
BACKGROUND Venous thromboembolism (VTE) is a well-recognized complication after total joint replacement (TJR). Persons with hemophilia A or B are considered at low postoperative VTE risk due to their coagulation factor deficiencies, and administering pharmacologic thromboprophylaxis is often considered contraindicated. However, using factor replacement therapy could increase the postoperative VTE risk. OBJECTIVES To analyze best available evidences of VTE rates in persons with hemophilia A or B undergoing lower limb TJR and the use of postoperative pharmacologic thromboprophylaxis. METHODS We systematically screened 4 online biomedical databases to identify studies reporting VTE rates in patients with hemophilia after TJR. Case reports and case series with less than 10 patients were excluded. RESULTS Twenty-six observational studies were included in this systematic review, reporting 1181 TJRs in patients with hemophilia A or B. Eight studies had VTE rates as the primary outcome. Five studies reported screen-detected VTE, while 21 reported symptomatic VTE events. Overall, 17 VTE events were reported (1.4%; 95% CI, 0.9%-2.3%), including 10 (6.6%) after 151 surgeries with postoperative VTE screening and 7 (0.7%) after 1080 surgeries without postoperative screening. Thromboprophylaxis protocols were specified in 21 studies; postoperative thromboprophylaxis was used in 15 (1.3%) surgeries. This information was not available for 29.0% of the analyzed population. CONCLUSION Despite the low thromboprophylaxis use in patients with hemophilia, rates of symptomatic VTE after TJR appeared to be low. We also highlighted the need to better report the thrombotic outcome in persons with hemophilia to face the ongoing changes in the hemophilia landscape.

Abstract
INTRODUCTION The increased life expectancy of patients with haemophilia A (HA) has led to a growing prevalence of cardiovascular risk factors and events. There is still scarce evidence on the safety and appropriate duration of dual antiplatelet therapy (DAPT) after acute coronary syndrome (ACS) in HA patients. AIM We describe our experience on the clinical management of Italian HA patients after ACS. METHODS Nine patients with congenital HA treated with DAPT after a revascularization procedure performed for ACS have been enrolled and followed at the Angelo Bianchi Bonomi Haemophilia and Thrombosis Center in Milan between 2005 and September 2022. The safety and efficacy of DAPT with or without FVIII prophylaxis were assessed. RESULTS Ten ACS events occurred in the nine HA patients (four mild and five severe). All events were treated with percutaneous transluminal coronary angioplasty with deployment of 1 to 3 drug-eluting stents followed by DAPT for 1-12 months. All patients except one were treated with FVIII prophylaxis during DAPT aimed at achieving FVIII trough levels ≥20-30 IU/dL. DAPT was effective in all cases in preventing early ACS recurrence, with only a late recurrence. We observed two clinically relevant non-major bleeds (one in a patient without FVIII prophylaxis) and three minor bleeds. No venous thrombosis occurred. CONCLUSION The long-term secondary antithrombotic prevention consisting of DAPT and FVIII prophylaxis achieving a trough level of 20-30 IU/dL can be effective and safe in HA patients.

Abstract
Key Clinical Message The increased life expectancy in patients with hemophilia (PwH) over the last years has raised the incidence of comorbidities, including thromboembolic events. Thromboembolic events are rare in PwH and most of them occur in the presence of exogenous risk factors. There is still scarce scientific evidence on the optimal antithrombotic treatment and management approach in this population. Abstract In the hemophilic population thromboembolic events are rare. Most of them are often multifactorial and occur in the presence of both exogenous (orthopedic surgery, intensive replacement therapy, use of central venous catheters…) and endogenous (cardiovascular diseases) risk factors. We describe the case of a 43-year-old patient with severe hemophilia B (sHB) receiving prophylaxis with eftrenonacog alfa (rFIXFc) and antithrombotic treatment due to portal vein thrombosis. The patient was treated with extended half- life factor IX (EHL-FIX) prophylaxis maintaining higher trough levels to avoid new bleeding episodes associated to the underlying disease and the use of antithrombotic therapy with low molecular weight heparin. EHL-FIX concentrates allow prolonged intervals between intravenous infusions and higher hemostatic protection thanks to increased factor trough levels. This current case report provides clinical evidence in antithrombotic management in a patient with severe hemophilia B.

Abstract
INTRODUCTION Balancing antithrombotic therapy for atrial fibrillation (AF) patients undergoing percutaneous coronary intervention (PCI) remains a clinical challenge due to coexisting thrombogenic risks. This review emphasizes the delicate balance required to prevent ischemic events while minimizing bleeding complications, particularly in the context of risk assessment. AREAS COVERED This review spans from 2010 to October 2023, exploring the complexities of antithrombotic management for AF patients undergoing PCI. It stresses the need for personalized treatment decisions to optimize antithrombotic therapies effectively. EXPERT OPINION The evolving evidence supports double antithrombotic therapy (DAT) over triple antithrombotic therapy (TAT) for these patients, showcasing a more favorable safety profile without compromising efficacy. Non-vitamin K antagonist oral anticoagulant (NOAC)-based DAT strategies exhibit superiority in reducing major bleeding events while effectively preventing ischemic events. Recommendations from the 2023 European Society of Cardiology (ESC) Guidelines advocate for NOAC-based DAT post-PCI, endorsing safer antithrombotic profiles.Challenges persist for specific patient categories requiring both oral anticoagulants and antiplatelets, necessitating personalized approaches. Future advances in intravascular imaging and novel coronary stent technologies offer promising avenues to optimize outcomes and influence antithrombotic strategies in AF-PCI patients.

Abstract
Background Thrombotic events in congenital factor (F)XIII deficiency are extremely rare. To our knowledge, we describe the first case of severe congenital FXIII deficiency associated with recurrent venous thrombotic events. Key Clinician Question How to deal with anticoagulation treatment in patients with severe FXIII deficiency? Clinical Approach The patient was treated with rivaroxaban and plasma-derived FXIII substitution therapy as prophylaxis without bleeding complications. We aimed at FXIII trough levels of 50% during the loading doses of rivaroxaban, then 30% during the maintenance dose of rivaroxaban, and finally 20% during the long-term use of prophylactic dose of rivaroxaban. Conclusion Treatment of thrombotic events with rivaroxaban in patients with severe bleeding disorders seems to be safe, requiring an adaptation of the intensity of the replacement therapy.

Abstract
INTRODUCTION Immune thrombotic thrombocytopenic purpura (iTTP) is a rare and life-threatening disorder. Caplacizumab has been the latest drug incorporated into the initial treatment of acute episodes, allowing for faster platelet recovery and a decrease in refractoriness, exacerbation, thromboembolic events, and mortality. However, caplacizumab is also associated with a bleeding risk and higher treatment costs, which prevent many centers from using it universally. AREAS COVERED Studies that included iTTP and/or caplacizumab to date were selected for this review using PubMed and MEDLINE platforms. We describe outcomes in the pre-caplacizumab era and after it, highlighting the benefits and risks of its use early in frontline, and also pointing out special situations that require careful management. EXPERT OPINION It is clear that the availability of caplacizumab has significantly and favorably impacted the management of iTTP patients. Whether this improvement is cost-effective still remains uncertain, and data on long-term sequelae and different healthcare systems will help to clarify this point. In addition, evidence of the bleeding/thrombotic risk of iTTP patients under this drug needs to be better addressed in future studies.

The in vitro effect of anticoagulant agents on coagulation and fibrinolysis in the presence of emicizumab in the plasmas from patients with haemophilia A. Haemophilia 2023; 29:1529-1538. [PMID: 37766492 DOI: 10.1111/hae.14877] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2023] [Revised: 09/11/2023] [Accepted: 09/19/2023] [Indexed: 09/29/2023]
Abstract
INTRODUCTION Emicizumab is used as hemostatic prophylaxis for patients with hemophilia A (PwHA), irrespective of the presence of inhibitors. Although bacterial infection can lead to a procoagulant state, there is limited information on coagulation and fibrinolysis potentials in emicizumab-treated PwHA and on the use of anticoagulants in such cases. AIM We examined whether anticoagulants affect the coagulation and fibrinolysis potentials in plasma from PwHA spiked with emicizumab. METHODS Plasma from PwHA was in vitro supplemented with emicizumab (50 μg/mL; emi-plasma) and anticoagulants (recombinant thrombomodulin (rTM), nafamostat mesylate (NM), unfractionated heparin (UFH), or low-molecular-weight heparin (LMH)). PwHA plasma spiked with rFVIII (1 IU/mL) was used as a reference (ref-plasma). The coagulation and fibrinolysis potentials in plasma was measured by thrombin and plasmin generation assay (T/P-GA) and clot-fibrinolysis waveform analysis (CFWA). RESULTS In T/P-GA and CFWA, coagulation potentials (maximum coagulation velocity; |min1|, and peak thrombin; Th-Peak) in plasma rose with increasing concentrations of emicizumab and rFVIII, but fibrinolytic potentials (peak plasmin; Plm-Peak, and maximum fibrinolytic velocity; |FL-min1|) remained unchanged. Adding rTM, NM, and UFH to emi-plasma suppressed coagulation and fibrinolysis potentials, similar to ref-plasma. Regarding the heparin, UFH and LMH inhibited the improved coagulation in emi-plasma. UFH inhibited fibrinolysis as well, but LMH did not. CONCLUSIONS Anticoagulants could exhibit the inhibitory effects on the coagulation and fibrinolysis potentials in plasma from PwHA spiked with emicizumab, similar to those in normal plasma.

Lassila R, Weisel JW. Role of red blood cells in clinically relevant bleeding tendencies and complications. J Thromb Haemost 2023; 21:3024-3032. [PMID: 37210074 PMCID: PMC10949759 DOI: 10.1016/j.jtha.2023.05.009] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Revised: 04/20/2023] [Accepted: 05/10/2023] [Indexed: 05/22/2023]
Abstract
The multiple roles of red blood cells (RBCs) are often neglected as contributors in hemostasis and thrombosis. Proactive opportunities to increase RBC numbers, either acutely or subacutely in the case of iron deficiency, are critical as RBCs are the cellular elements that initiate hemostasis together with platelets and stabilize fibrin and clot structure. RBCs also possess several functional properties to assist hemostasis: releasing platelet agonists, promoting shear force-induced von Willebrand factor unfolding, procoagulant capacity, and binding to fibrin. Additionally, blood clot contraction is important to compress RBCs to form a tightly packed array of polyhedrocytes, making an impermeable seal for hemostasis. All these functions are important for patients having intrinsically poor capacity to cease bleeds (ie, hemostatic disorders) but, conversely, can also play a role in thrombosis if these RBC-mediated reactions overshoot. One acquired example of bleeding with anemia is in patients treated with anticoagulants and/or antithrombotic medication because upon initiation of these drugs, baseline anemia doubles the risk of bleeding complications and mortality. Also, anemia is a risk factor for reoccurring gastrointestinal and urogenital bleeds, pregnancy, and delivery complications. This review summarizes the clinically relevant properties and profiles of RBCs at various steps of platelet adhesion, aggregation, thrombin generation, and fibrin formation, including both structural and functional elements. Regarding patient blood management guidelines, they support minimizing transfusions, but this approach does not deal with severe inherited and acquired bleeding disorders where a poor hemostatic propensity is exacerbated by limited RBC availability, for which future guidance will be needed.
