Abstract

BACKGROUND: Only small randomized trials have investigated the efficacy and safety of direct oral anticoagulants (DOACs) compared with vitamin K antagonists (VKAs) in patients with non-valvular atrial fibrillation (NVAF) and end-stage kidney disease.

OBJECTIVES: To perform a systematic review and meta-analysis comparing anticoagulation with DOACs to VKAs in patients with NVAF undergoing chronic hemodialysis.

METHODS: A systematic search using Medline, Web of Science, and Embase was performed. All randomized trials comparing DOACs with VKAs in patients with NVAF undergoing chronic hemodialysis were included. As primary endpoint, we analyzed all-cause mortality. As secondary endpoints, we investigated total bleeding events, life-threatening or major bleeding events, and thromboembolic events or stroke. We used the odds ratio as outcome measure and fitted a random-effects model due to the expected heterogeneity.

RESULTS: Three studies fulfilled the inclusion criteria comprising 383 patients (218 on apixaban or rivaroxaban, 165 on VKA). No significant difference between DOACs and VKAs regarding death (OR, 0.94; 95% CI, 0.55-1.63; p = .84), total bleedings (OR, 0.99; 95% CI, 0.63-1.54; p = .96) and life-threatening or major bleeding (OR, 0.65; 95% CI, 0.32-1.33, p = .24) was detected. There was a trend toward a reduction of thromboembolic events or stroke in patients receiving DOACs (OR, 0.39; 95% CI, 0.14-1.05; p = .06).

CONCLUSION: Orally administered activated factor X inhibitors carried a similar risk of bleeding and death when compared with VKAs in patients with NVAF undergoing chronic hemodialysis. Moreover, there was a trend towards a reduction of thromboembolic events or stroke in patients receiving DOACs.
