Primary prophylaxis of venous thromboembolic disease with direct oral anticoagulants in patients with severe inherited thrombophilia.

Direct oral anticoagulants (DOACs) are widely used in several indications, but data on their efficacy and safety in individuals affected by severe inherited thrombophilia, yet without any personal history of thrombosis, is lacking. Severe inherited thrombophilia abnormalities, especially antithrombin deficiency, confer a higher risk of developing venous thromboembolism (VTE) than is the case in the general population. In this article, we propose primary prevention with low-dose DOACs for certain patients with severe inherited thrombophilia but without any personal history of VTE, while taking into consideration the type of thrombophilia, family history, comorbidities, and bleeding risk.
