Although direct-acting oral anticoagulants (DOACs) decrease the bleeding risk compared with vitamin K antagonists (VKAs), DOACs might cause spontaneous hemothorax in very elderly patients, even at a very low dose. Interactions between drugs might increase the risk of bleeding. In this article, we report a case of a 95-year-old man who developed spontaneous hemothorax while taking rivaroxaban 2.5 mg twice daily, 3 days after concomitant use of itraconazole. Rivaroxaban was discontinued, and thoracentesis was performed to drain grossly bloody pleural effusion. To our knowledge, this is the first case report of spontaneous hemothorax that might have been caused by concomitant low-dose rivaroxaban and azole anti-fungal agents. This case highlights the potential risk of spontaneous hemothorax in very elderly patients while taking rivaroxaban and azole anti-fungal agents simultaneously. Special attention should be paid to interactions between drugs that might increase the risk of bleeding. Drugs that have competing metabolic pathways should be avoided. Closer monitoring, including testing for anti-Xa and additional reassessment, should be considered in high-risk patients.

Abstract Aims The real-life benefits and risks of the non-vitamin K antagonist oral anticoagulants for stroke prevention in very elderly patients with atrial fibrillation (AF) are still debated. Methods and results Cohorts of new users of rivaroxaban 15 mg, dabigatran 110 mg, or vitamin K antagonists (VKA) for AF ≥85 years old in 2013 or 2014 were identified in the nationwide French claims database and followed-up for 1 year. Cohorts were compared after 1:1 matching using high-dimensional propensity score. Compared to VKA use and considering 1-year cumulative incidences, risk of stroke, and systemic embolism was not different with rivaroxaban use [hazard ratio 1.14, 95% confidence interval (CI): 0.93–1.40] and lower with dabigatran use (0.77, 95% CI: 0.60–0.99), risk of major bleeding was not different with rivaroxaban use (0.91, 95% CI: 0.74–1.11) and with dabigatran use (0.81, 95% CI: 0.64–1.03), risk of all-cause death was borderline to significance lower with rivaroxaban use (0.91, 95% CI: 0.83–1.00), and lower with dabigatran use (0.87, 95% CI: 0.78–0.97). The risk for a composite of all events above was not different with rivaroxaban use (0.96, 95% CI: 0.88–1.04) and lower with dabigatran use (0.87, 95% CI: 0.79–0.96) as compared with VKA use. The risk for the composite of all events was not different with rivaroxaban use as compared with dabigatran use (1.09, 95% CI: 0.97–1.23). Conclusion This study shows for the first time in more than 25 000 new real-life anticoagulant users for AF aged ≥85 years a neutral overall benefit-risk of rivaroxaban 15 mg vs. VKA and a favourable overall benefit-risk of dabigatran 110 mg vs. VKA on relevant clinical events.

Reduced Kidney Function

Over the last decade, the number of people aged 80 years or over in Russia increased by 41% up to 5.7 mln. At least 10% of these individuals develop atrial fibrillation (AF). Treatment of rhythm disorders in the very elderly patients is challenging due to the high occurrence of comorbidities, including cognitive dysfunction, changes in the pharmacokinetics of drugs as a result of reduced kidney function, increased risk of interaction of drugs. The very elderly patients with AF have a higher risk of ischemic stroke and other cardiovasculat outcomes, including myocardial infarction, and should be treated with oral anticoagulants. The results of randomized controlled trials and prospective and retrospective observational studies suggest that in patients aged 80 years or older with non-valvular AF direct oral anticoagulants (DOAC) are at least as effective as vitamin K antagonists for prevention of ischemic stroke and are associated with a lower risk of intracerebral haemorrhage. The use of DOAC (once daily rivaroxaban in particular) impoves compliance to anticoagulation in the very elderly patients with non-valvular AF.

Proportional Incidence

Abstract Background Falls from standing are common in the elderly and are associated with a significant risk of bleeding. We have compared the proportional incidence of bleeding complications in patients on either direct oral anticoagulants (DOAC) or vitamin K antagonists (VKA). Methods Our retrospective cohort study compared elderly patients (≥65 years) on DOAC or VKA oral anticoagulation who presented at the study site – a Swiss university emergency department (ED) – between 01.06.2012 and 01.07.2017 after a fall. The outcomes were the proportional incidence of any bleeding complication and its components (e.g. intracranial haemorrhage), as well as procedural and clinical parameters (length of hospital stay, admission to intensive care unit, in-hospital-mortality). Uni- and multivariable analyses were used to compare the studied outcomes. Results In total, 1447 anticoagulated patients were included – on either VKA (n = 1021) or DOAC (n = 426). There were relatively more bleeding complications in the VKA group (n = 237, 23.2%) than in the DOAC group (n = 69, 16.2%, p = 0.003). The difference persisted in multivariable analysis with 0.7-fold (95% CI: 0.5–0.9, p = 0.014) lower odds for patients under DOAC than under VKA for presenting with any bleeding complications, and 0.6-fold (95% 0.4–0.9, p = 0.013) lower odds for presenting with intracranial haemorrhage. There were no significant differences in the other studied outcomes. Conclusions Among elderly, anticoagulated patients who had fallen from standing, those under DOACs had a lower proportional incidence of bleeding complications in general and an even lower incidence of intracranial haemorrhage than in patients under VKAs.

Massive Rectal Bleeding

The recent introduction of direct oral anticoagulants, including rivaroxaban, dabigatran, apixaban, and edoxaban, for the acute treatment and secondary prevention of venous thromboembolism and in atrial fibrillation has been shown to provide greater clinical benefit than oral vitamin K antagonists. However, direct oral anticoagulants are associated with adverse events, the most common being major bleeding; such events require the reversal of the anticoagulant effects by specific agents. In this case report, we describe an 87-year-old female with atrial fibrillation treated with dabigatran who had massive rectal bleeding. Idarucizumab 5 g (2 × 2.5 g/50 mL) was successfully used to reverse dabigatran effect; subsequent to this, treatment with dabigatran was resumed, and there were no further bleeding events. This suggests that dabigatran can be safely restarted after major bleeding, but this outcome needs to be confirmed in studies involving larger groups of patients.

We compared very elderly people taking vitamin K antagonists (VKA) and those not taking VKA (noVKA). Individuals were included in the noVKA group if there was no VKA on their reimbursed prescriptions during the study period. We also compared three subgroups, constituted by VKA type (fluindione, warfarin, or acenocoumarol). We included individuals aged over 85 years, affiliated to Mutualité Sociale Agricole of Burgundy, who were refunded for prescribed VKA in September 2017. The VKA and noVKA groups were compared in terms of demographic conditions, registered chronic diseases (RCD), number of drugs per prescription and cardiovascular medications. The three VKA subgroups were compared for the same items plus laboratory monitoring, novel and refill VKA prescriptions, and prescriber specialty. Of the 8696 included individuals, 1157 (13.30%) were prescribed VKA. Mean age was 90 years. The noVKA group had fewer women (53.67 vs 66.08%), more RCD (93.43 vs. 71.96%) and more drugs per prescription (6.65 vs. 5.18) than the VKA group (all p < 0.01). Except for direct oral anticoagulants and platelet aggregation inhibitors, the VKA group took significantly more cardiovascular medications. The most commonly prescribed VKA was fluindione (59.46%). Mean age was higher in the warfarin (90.42) than in the acenocoumarol (89.83) or fluindione (89.71) subgroups (p < 0.01). No differences were observed for sex (women were predominant) or RCD. 13% of subjects in this population had a VKA prescription. Fluindione was the most commonly prescribed VKA.

Risk Of Bleeding

Venous thromboembolism, a frequent and severe disease, has clinically important early and late complications and a strong tendency to recur. Anticoagulant therapy is the mainstay of treatment, performed by immediate administration of: i) parenteral anticoagulants followed by vitamin K antagonists, either dabigatran or edoxaban, two direct oral anticoagulants (DOACs); or ii) direct rivaroxaban or apixaban, two DOACs that can be used as single-drug approach. Treatment should last no less than 3 months in all patients though how long it should last thereafter is a more complex issue. The risk of recurrence results from several event- or patient-associated factors. Some patients have low risk and may be treated for 3 to 6 months only. Others (the majority) have a high risk of recurrence (approximately 50% in 10 years). Unfortunately, the protective effect of anticoagulation against recurrence is present only during treatment and is lost when therapy is stopped. For this reason, international guidelines recommend that there is no pre-definite period of anticoagulation (e.g. 1 or 2 years, and so on) in patients at high risk and suggest instead indefinite (extended) anticoagulation, provided there is no high risk of bleeding. When the decision is difficult, adjunctive criteria may be adopted, such as male sex and abnormal D-dimer assessed after anticoagulation is stopped, to identify patients at high risk who need indefinite therapy. The use of DOACs, especially at lower doses with a lower risk of bleeding, may make indefinite anticoagulation for patients easier.

Background Advancing age is a major risk factor for ischemic stroke in atrial fibrillation. We aimed to evaluate the predictors of all-cause death/any thromboembolism and the impact of oral anticoagulant on clinical outcomes in very elderly (≥85 years) Chinese atrial fibrillation patients. Methods The ChiOTEAF is a prospective registry proceeded in 44 sites from 20 provinces in China between October 2014 and December 2018. Outcomes of interest were all-cause mortality, any thromboembolism, major bleeding, and new onset/worsening heart failure. Results The eligible cohort for this analysis included 6416 patients and 1215 (18.9%) patients were aged ≥85 years. Only 320 (26.4%) very elderly patients were treated with oral anticoagulant, of whom 205 (64.1%) received non-vitamin K antagonist oral anticoagulants, while antiplatelet therapy was used among 642 (53.1%) very elderly patients. On multivariate analysis, the use of oral anticoagulant was an independent predictor of a lower risk of the composite outcome (OR: 0.46; 95% CI: 0.32–0.66) and all-cause death (OR: 0.47; 95% CI: 0.32–0.69) among these very elderly atrial fibrillation patients. Conclusions Advanced age should not be a reason to withhold oral anticoagulant, since the use of oral anticoagulants is safe and improves survival.
