Abstract Background Direct oral anticoagulants have been demonstrated to have advantages in several patient populations compared with warfarin. However, the safety and efficacy are controversial between direct oral anticoagulants and warfarin in patients with chronic kidney disease, especially on dialysis, who have been excluded from randomised controlled trials. Purpose The purpose of this study was to investigate the safety and the efficacy of direct oral anticoagulants as compared to warfarin in patients on dialysis. Methods A meta-analysis was conducted on clinical studies in patients requiring oral anticoagulation and dialysis. PubMed, the Cochrane Library, and Web of Science were queried for the terms “dialysis”, “warfarin”, and “apixaban OR dabigatran OR rivaroxaban OR edoxaban”. The same terms or relevant studies were also queried on the website of the U.S. National Institute of Health and relevant reviews. The clinical endpoints were stroke/systemic embolism and major bleeding. Pooled estimates were calculated using a random-effects model. Results Six observational studies (18487 patients) were included in this study. The risk of major bleeding (odds ratio (OR) 0.45; 95% confidence interval (CI) 0.31–0.65; p<0.01) was lower in patients on direct oral anticoagulants compared to those on warfarin, whereas the risk of stroke/systemic embolism (OR0.63; 95% CI 0.30–1.33; p=0.23) was similar between the two types of anticoagulant. Conclusions Direct oral anticoagulants are associated with a lower risk of major bleeding and a similar risk of stroke/systemic embolism compared to warfarin in patients on dialysis. To validate these findings, randomised controlled trials are warranted. Funding Acknowledgement Type of funding source: None

Abstract Direct oral anticoagulants (DOACs) are an emerging treatment option for patients with cancer and acute venous thromboembolism (VTE), but studies have reported inconsistent results. This systematic review and meta-analysis compared the efficacy and safety of DOACs and low-molecular-weight heparins (LMWHs) in these patients. MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, and conference proceedings were searched to identify relevant randomized controlled trials. Additional data were obtained from the original authors to homogenize definitions for all study outcomes. The primary efficacy and safety outcomes were recurrent VTE and major bleeding, respectively. Other outcomes included the composite of recurrent VTE and major bleeding, clinically relevant nonmajor bleeding (CRNMB), and all-cause mortality. Summary relative risks (RRs) were calculated in a random effects meta-analysis. In the primary analysis comprising 2607 patients, the risk of recurrent VTE was nonsignificantly lower with DOACs than with LMWHs (RR, 0.68; 95% CI, 0.39-1.17). Conversely, the risks of major bleeding (RR, 1.36; 95% CI, 0.55-3.35) and CRNMB (RR, 1.63; 95% CI, 0.73-3.64) were nonsignificantly higher. The risk of the composite of recurrent VTE or major bleeding was nonsignificantly lower with DOACs than with LMWHs (RR, 0.86; 95% CI, 0.60-1.23). Mortality was comparable in both groups (RR, 0.96; 95% CI, 0.68-1.36). Findings were consistent during the on-treatment period and in those with incidental VTE. In conclusion, DOACs are an effective treatment option for patients with cancer and acute VTE, although caution is needed in patients at high risk of bleeding.

Patients with cancer may experience venous thromboembolism (VTE), leading to various medical complications or death, more often than the population without cancer. Moreover, patients with cancer usually experience both higher rates of recurrent VTE and bleeding. For the past decade, low-molecular-weight heparin (LMWH) has been considered a standard therapy for VTE related to cancer; however, daily injections of LMWH have augmented the burden of neoplastic disease and decreased adherence to therapy in some patients. At present, direct oral anticoagulants (DOAC) such as factor Xa inhibitors (e.g., rivaroxaban, edoxaban, and apixaban) have been recommended as a new treatment modality, mostly because of their convenient use (i.e., the oral route of delivery) for the patient population with cancer. Notably, large recent randomised controlled trials that have compared DOACs with LMWH in patients with malignancies have revealed that DOACs represent a valuable alternative to LMWH for the therapy of VTE related to cancer. Despite their unique advantages, the DOACs may not be appropriate for some groups of patients with cancer due to their elevated risk of bleeding, among other factors. This mini-review presents the main findings from some recent randomised controlled trials, comparing the use of DOACs and LMWH for the management of VTE associated with malignancy. It highlights the efficacy, safety, and various other considerations of treatment and prophylaxis of VTE depending on the individual patient context. It provides current guidance on the selection of the optimal anticoagulant for comprehensive and personalised patient care.

Vitamin K antagonists, such as warfarin, have been the anticoagulants of choice for many years for patients with AF and other thrombotic conditions. The introduction of direct oral anticoagulants (DOACs) as alternatives represents a major advance in anticoagulation. DOACs have been found to be at least as safe and effective as vitamin K antagonists in randomised, controlled trials for stroke prevention in AF and the management of venous thromboembolism, with real-world data showing similar outcomes. With the availability of several agents, selecting the most appropriate DOAC can be challenging. The aim of the present article is to provide useful guidance on the implementation of DOAC treatment in clinical practice.

Acute Venous Thromboembolism

Abstract Background International guidelines have endorsed the use of edoxaban or rivaroxaban as an alternative to low-molecular-weight heparin (LMWH) for the treatment of acute venous thromboembolism (VTE) in cancer patients. Recently, a large randomized controlled trial of apixaban versus dalteparin in patients with cancer was completed. We performed an updated meta-analysis to assess the efficacy and safety of direct oral anticoagulants (DOACs) versus LMWH in patients with cancer-associated VTE. Methods MEDLINE, EMBASE, and CENTRAL (Cochrane Controlled Trials Registry) were systematically searched up to March 30, 2020 for randomized controlled trials comparing DOACs versus LMWH for the treatment of VTE in patients with cancer. The two coprimary outcomes were recurrent VTE and major bleeding at 6 months. Data were pooled by the Mantel–Haenszel method and compared by relative risk ratios (RRs) and 95% confidence intervals (CIs). Results Four randomized controlled studies (2,894 patients) comparing apixaban, edoxaban, or rivaroxaban with dalteparin were included in the meta-analysis. Recurrent VTE occurred in 75 of 1,446 patients (5.2%) treated with oral factor Xa inhibitors and in 119 of 1,448 patients (8.2%) treated with LMWH (RR 0.62; 95% CI 0.43–0.91; I 2, 30%). Major bleeding occurred in 62 (4.3%) and 48 (3.3%) patients receiving oral factor Xa inhibitors or LMWH, respectively (RR 1.31; 95% CI 0.83–2.08; I 2, 23%). Conclusion In patients with cancer-associated VTE, oral factor Xa inhibitors reduced the risk of recurrent VTE without a significantly higher likelihood of major bleeding at 6 months compared with LMWH.
