| Popis: | Background Evidence for direct oral anticoagulants (DOACs) in patients with cirrhosis is limited. Few patients with Child-Turcotte-Pugh (CTP) class B and C cirrhosis have been studied. Objective To compare major bleeding rates in patients with cirrhosis receiving a DOAC versus warfarin. Methods A retrospective cohort study was conducted in adults with cirrhosis receiving a DOAC versus warfarin for venous thromboembolism, portal-vein thrombosis, or atrial fibrillation. The primary outcome was the rate of major bleeding. Secondary outcomes included time to major bleeding, clinically relevant nonmajor bleeding, all bleeding, gastrointestinal bleeding, intracranial bleeding, and new thromboembolic events. The study was approved by the Ochsner Health System Institutional Review Board. Results A total of 44 patients receiving a DOAC and 41 patients receiving warfarin were included. Major bleeding occurred in 4 patients receiving a DOAC and 6 patients receiving warfarin (9.1% vs 14.6%; P = 0.881). Rates of major bleeding were similar in 24 DOAC and 17 warfarin patients with CTP Class B (4.2% vs 17.6%; P = 0.37) and 8 DOAC and 9 warfarin patients with CTP Class C (37.5% vs 11.1%; P = 0.41) cirrhosis. Secondary bleeding and efficacy outcomes were similar between cohorts. The study was limited by a small sample size. Conclusion and Relevance Treatment with DOACs in patients with cirrhosis was associated with a similar rate of major bleeding compared with warfarin. Inclusion of CTP class C patients in future studies remains valuable to evaluate safety and efficacy of DOACs in this population. |
