ABSTRACT
Research on cerebrovascular events in atrial fibrillation (AF) patients taking non-vitamin K antagonist oral anticoagulants (NOACs) with antiseizure medications (ASMs) is limited, highlighting a significant gap in literature. We assessed thrombotic and hemorrhagic risks in patients on NOACs and ASMs versus those on NOACs or ASMs alone. We analyzed a retrospective cohort from five centers, including AF and epilepsy patients on both medications (n = 188), AF patients on NOACs (n = 298), and epilepsy patients on ASMs (n = 50), with a 3-year follow-up. Propensity score matching adjusted for cardiovascular risk differences. The primary outcomes were ischemic stroke, transient ischemic attack, and major bleeding. Results showed the ASM+NOAC group had a higher risk of primary outcomes compared to the NOAC-only group (5.68% vs. 1.18%, hazard ratio = 5.72, 95% confidence interval = 2.22-14.73), with no events in the ASM-only group. This suggests an increased risk for patients on combined NOAC and ASM therapy, underlining the need for careful drug interaction consideration.

OBJECTIVES: Patients affected by eosinophilic granulomatosis with polyangiitis (EGPA) display an increased risk of atherothrombotic events compared with the general population. An increased frequency of subclinical markers of atherosclerosis has been observed in other ANCA-associated vasculitis, but no specific study focused on EGPA. We therefore evaluated subclinical atherosclerosis in EGPA patients and in a control population. METHODS: Forty EGPA patients and 80 controls matched by age, sex and traditional cardiovascular risk factors underwent sonographic assessment of common carotid artery (CCA) intima-media thickness (IMT). The presence of plaques of the CCA was also investigated. The correlation between CCA-IMT and clinical and laboratory features was also assessed. RESULTS: Median CCA-IMT was significantly higher in EGPA patients compared with controls (P = 0.002). Also, the proportion of subjects with increased CCA-IMT and with presence of plaques was significantly higher among EGPA patients (P < 0.001 for both). Moreover, within the EGPA cohort, CCA-IMT tended to increase with disease duration (P = 0.034) and corticosteroid cumulative dose (P = 0.004). No significant associations were found between CCA-IMT, ANCA status, other clinical features and therapeutic regimens. Notably, the prevalence of traditional cardiovascular risk factors was comparable in patients with vs without an increased CCA-IMT. CONCLUSION: Ultrasound markers of subclinical atherosclerosis are increased in EGPA patients as compared with controls, independently of traditional cardiovascular risk factors.

Stroke is one of the most common causes of mortality and disability worldwide. Antithrombotic therapy represents the mainstay in primary and secondary prevention, both in cardioembolic and non-cardioembolic stroke. Particularly, direct oral anticoagulants play a crucial role in atrial fibrillation, the most common cause of cardioembolic stroke, whereas single or dual antiplatelet therapy is preferred in non-cardioembolic stroke. However, the limitations related to the residual risk of cardioembolic or cerebrovascular events, and the risk of major bleeding, still represent unmet medical needs. To overcome them, new drugs inhibiting Factor XI (FXI) and Factor XII have been proposed, with a selective inhibition of contact pathway of coagulation, delineating a new anticoagulant approach. This review provides a summary of the currently available evidence and future perspectives on FXI inhibitors, that can represent an additional therapeutic option in the primary and secondary prevention of cardioembolic and non-cardioembolic ischemic stroke, also in challenging therapeutic contexts.
ABSTRACT
Introduction: Patients with Haemophilia (PWH) need orthopaedic treatments and often they undergo surgery. Classically, PWH with inhibitors have to face such procedures earlier than other patients. Major orthopaedic surgery is not easy and complications are frequent. Emicizumab is the first monoclonal antibody introduced for haematological prophylaxis for PWH with inhibitors, achieving an efficacious haemostasis also in patients with severe haemophilia A with inhibitors, later demonstrated for PWH without inhibitors. A few years ago, emicizumab was also proposed for PWH undergoing surgery, as it supports excellent bleeding control. The literature on orthopaedic surgery using an emicizumab protocol is scarce: only isolated case reports with short-term follow-ups are available. Aim: The purpose of this study is the assessment of the mid-term outcomes of major orthopaedic surgery performed in a population of patients with and without inhibitors and an emicizumab regimen. Methods: We reviewed the records of 13 PWH (eight with high-titre inhibitors, five without) with a mean age of 54.6 years, undergoing 15 orthopaedic surgical procedures between 2017 and 2022: primary knee and hip arthroplasty, revision, pseudotumor excision, or amputation. Their prophylaxis consisted of the combination of emicizumab and boluses of rFVIIa (PWH with inhibitors) or rFVIII (PWH without inhibitors). The clinical parameters of evaluation were: VAS, Haemophilic Joint Health Score (HJHS), and standard radiologic studies. Follow-up was conducted at 1, 3, 6 months, and then yearly. The survival rate of all implants was also assessed. Results: The mean follow-up was 38.8 months (range: 12-65). All patients were successfully treated without complications during surgery. During the postoperative period, a patient affected by a septic complication two months after his pseudotumor excision underwent an above-the-knee amputation. All patients were regularly discharged to the rehabilitative ward, reporting satisfaction for pain reduction and improved joint and global function at the VAS and HJHS scores. No revisions or implant failures were recorded. Conclusions: A prophylaxis regimen with emicizumab and factor replacement in PWH with or without inhibitors undergoing major orthopaedic surgery ensures effective bleeding control and good postoperative clinical outcomes at mid-term follow-up, and may be routinely adopted in dedicated high-volume hospitals. This series is the most consistent to date reported at a single Haemophilia centre.
ABSTRACT
BACKGROUND: So far, the only available data for edoxaban periprocedural management come from the ENGAGE AF-TIMI 48 trial. The recently published EMIT-AF/VTE study showed low periprocedural bleeding and thromboembolic risks of edoxaban in a real-world setting in patients undergoing any diagnostic or therapeutic procedures. The aim of this study was to compare descriptively Italian and European data with regard to patient characteristics and outcomes in the EMIT-AF/VTE study. METHODS: A total of 1155 patients treated with edoxaban for stroke prevention in non-valvular atrial fibrillation and with venous thromboembolism, and undergoing a wide range of diagnostic and therapeutic procedures were enrolled in 326 centers across Europe. Of these patients, 246 were from 43 Italian centers. The periprocedural interruption of edoxaban was at the physician's discretion. All the procedures were classified into minor, low, and high bleeding procedural risk according to the European Heart Rhythm Association (EHRA) definition. The primary outcome was the incidence of major bleeding. Secondary outcomes included thromboembolic events. RESULTS: Patients were older in Italy in comparison with the rest of Europe with a mean age of 74.2 vs 71.3 years. Also, the rate of comorbidities was higher in Italy (e.g. diagnosed cancer and vascular disease) than in Europe. In Italy, there was a higher rate of high bleeding risk procedures than in other European countries (37.8% vs 20.6%) and a more homogeneous distribution of all types of procedures (while in Europe 44.1% were vascular access and transcatheter diagnostic procedures and interventions). In Italy, a higher proportion of patients did not interrupt edoxaban (32.9% vs 29% in Europe). The number of major bleeding events (2 in Italy, 3 in Europe) as well as of thromboembolic events (4 in Italy, 3 in Europe) was overall low. CONCLUSIONS: In the EMIT-AF/VTE study, the number of bleeding and thromboembolic events in patients treated with edoxaban undergoing elective or unplanned procedures was low either in Italy or in the rest of Europe. The safety and efficacy of edoxaban was confirmed in Italy even if patients were older, presented more frequently with cancer, and there was a higher rate of high bleeding risk procedures by EHRA definition.

BACKGROUND: European guidelines do not recommend the use of carbamazepine, levetiracetam, phenobarbital, phenytoin, topiramate and valproic acid in patients taking direct oral anticoagulants (DOACs). Little is known regarding the clinical relevance of the interaction between DOACs and antiepileptic drugs. OBJECTIVES: To evaluate the incidence of thromboembolic and bleeding events in patients with non-valvular atrial fibrillation (AF) concurrently treated with DOACs and antiepileptic drugs. METHODS: This is a prospective multicentre cohort study of patients with non-valvular AF concurrently treated with DOACs and antiepileptic drugs. The primary outcome was ischaemic stroke/transient ischaemic attack (TIA)/systemic embolism (SE). Secondary outcome was major bleeding (MB). Incidence rates (% patient-year) were evaluated for the study outcomes. RESULTS: Overall, 91 patients were included. Mean age was 78 ± 9.5 years, 49.5% were female. Mean CHA2DS2-VASc score was 4.76 ± 1.59 and mean HAS-BLED was 2.67 ± 1.26. Overall, 41, 20, 11, 10 and 9 out of 91 patients were treated with levetiracetam, valproic acid, phenobarbital, carbamazepine and other antiepileptic drugs, respectively. During a median follow-up of 17.5 ± 14.5 months, stroke/TIA/SE occurred in 9 patients (5.7% patient-year) and MB in 3 patients (1.9% patient-year). Ischaemic stroke was fatal in 3 patients (1.9% patient-year) and MB in one patient (0.6% patient-year). CONCLUSION: In this cohort, patients with non-valvular AF treated with DOACs and antiepileptic drugs appear to have a relatively high rate of thromboembolic events.

BACKGROUND: Limited data are available on the role of direct oral anticoagulants (DOACs) for the treatment of upper extremities deep vein thrombosis (UEDVT). OBJECTIVES: The aim of this study was to assess the effectiveness and safety of DOACs in the treatment of UEDVT. METHODS: Patients with an objectively confirmed acute UEDVT treated with DOACs were merged from prospective cohorts to a collaborative database. Primary study outcomes were recurrent venous thromboembolism (VTE) and major bleeding occurring during DOAC treatment. RESULTS: Overall, 188 patients were included in the study: mean age 52.4 ± 20.4 years, males 43.6%, patients with active cancer 29.2%. Twenty-nine percent of patients had 2 or more risk factors for VTE, 33.0% had catheter-related or pacemaker-related UEDVT. In 13.8% of patients, DOACs were started one month after UEDVT diagnosis or later. Active cancer was an independent predictor for delayed initiation of DOACs (OR 8.1, 95% CI 3.0-22.2). Mean duration of treatment with DOACs was 5.1 ± 2.8 months. During treatment with DOACs, recurrent VTE occurred in 0.9 per 100 patient-year, major bleeding in 1.7 and all-cause deaths in 6.0 per 100 patient-year. No fatal bleeding or fatal VTE recurrence were observed. During 232.1 patient-years of follow-up after DOAC withdrawal, recurrent VTE occurred in 3.0 per 100 patient-year. The 2019 ESC categories for risk of VTE recurrences were able to discriminate patient groups at different risk of events in the on and off-treatment periods. CONCLUSIONS: Our data support the feasibility as well as the effectiveness and safety of DOACs for the treatment of acute UEDVT.
