Resumo

A number of limitations of standard therapy with warfarin for deep vein thrombosis (DVT) have been established. This overview of systematic reviews presents the baseline results for efficacy and safety of the new direct oral anticoagulants (DOACs) thrombin inhibitors, and activated factor X (Xa) inhibitors in patients with DVT. Searches were run on PubMed and the Cochrane Database of Systematic Reviews. Twenty-three studies were retrieved, and one systematic review was judged eligible. This review scored maximum according to AMSTAR criteria and included 7,596 patients for analysis of thrombin inhibitors and 16,356 patients for analysis of factor Xa inhibitors. The results of the meta-analysis indicate that DOACs are similar for DVT treatment when compared to standard treatment with warfarin. The incidence of major bleeding is somewhat lower in patients treated with factor Xa inhibitors and similar to standard therapy when treated with direct thrombin inhibitors.

Abstract

A terapia padrão com varfarina para a trombose venosa profunda (TVP) tem uma série de limitações já estabelecidas. Essa revisão de revisões sistemáticas elenca os principais resultados de eficácia e segurança dos anticoagulantes orais diretos (DOACs), inibidores da trombina e do fator X ativado (Xa), em pacientes com TVP. A pesquisa foi realizada nas bases PubMed e Cochrane Database of Systematic Reviews. Foram recuperados 23 estudos, e uma revisão sistemática foi considerada elegível. Essa revisão atingiu escore máximo no AMSTAR e incluiu 7.596 pacientes para análise dos inibidores da trombina e 16.356 pacientes para a análise dos inibidores do fator Xa. Os resultados da metanálise indicam que os DOACs apresentam eficácia similar à terapia padrão no tratamento da TVP. A incidência de sangramento maior é um pouco menor nos pacientes tratados com os inibidores do fator Xa e similar à terapia padrão no tratamento com inibidores diretos da trombina.
