  • Efficacy and safety of direct oral anticoagulants in solid organ transplant recipients: a meta-analysis

    ObjectiveTo systematically evaluate the efficacy and safety of direct oral anticoagulants (DOACs) compared with vitamin K antagonists (VKA) in solid organ transplant (SOT) recipients. MethodsThe PubMed, Embase, Web of Science, Cochrane Library, CNKI, WanFang Data, CBM and VIP databases were electronically searched to collect clinical studies on DOACs (rivaroxaban, apixaban, idoxaban, dabigatran) compared with VKA in SOT recipients from inception to May 15, 2024. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was then performed by using RevMan 5.3 software. ResultsA total of 11 cohort studies involving 1 236 SOT recipients were included. The meta-analysis results showed that compared with VKA, DOACs could reduce the risk of any bleeding (RR=0.47, 95%CI 0.37 to 0.60, P<0.05) and major bleeding (RR=0.56, 95%CI 0.37 to 0.84, P<0.05) in SOT recipients. But there were no statistically significant differences in the total incidence of thrombotic events, VTE incidence, and stroke incidence between the two groups. ConclusionCurrent evidence shows that DOACs are not inferior to VKA in anticoagulation therapy for SOT recipients, but they perform better in terms of any bleeding and major bleeding. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
