Can a 57-year-old male with positive Antiphospholipid antibodies be treated with Eliquis (Apixaban)?

From the Guidelines

Eliquis (apixaban) is not recommended for a 57-year-old male with antiphospholipid antibody syndrome (APS) due to the increased risk of thrombotic events associated with direct oral anticoagulants (DOACs) in this patient population. According to the 2021 guideline for the prevention of stroke in patients with stroke and transient ischemic attack, DOACs, such as rivaroxaban, have been associated with a higher risk of thrombotic events in patients with antiphospholipid syndrome, particularly those with triple-positive antiphospholipid antibodies 1.

Key Considerations

• The use of DOACs in antiphospholipid syndrome is not recommended until further studies clarify whether the increased risk of thrombosis is a class effect or an individual drug effect 1.
• Warfarin, a vitamin K antagonist, remains the standard of care for thrombotic APS, with a target INR of 2.0-3.0 for patients with venous thrombosis, or a higher target INR of 3.0-4.0 for those with arterial thrombosis or recurrent events despite standard anticoagulation.
• Regular INR monitoring is necessary with warfarin therapy.
• The diagnosis and management of antiphospholipid syndrome require accurate detection and interpretation of antiphospholipid antibodies, as outlined in the updated guidance from the ISTH-SSC subcommittee on lupus anticoagulant/antiphospholipid antibodies 1.

Management Approach

• Consultation with a rheumatologist or hematologist is advisable to determine the most appropriate management strategy based on the patient's specific clinical presentation and antibody profile.
• The approach may differ for patients with only a single positive antiphospholipid antibody without clinical thrombotic events (carrier state).

From the Research

Antiphospholipid Syndrome and Eliquis Treatment

• The use of Eliquis (apixaban) in patients with antiphospholipid syndrome (APS) is a topic of ongoing debate, with some studies suggesting its potential use in certain cases, while others recommend caution or avoidance 2, 3, 4, 5, 6.
• According to a 2013 study, new oral anticoagulants (NOACs) like apixaban may be considered as an alternative to warfarin in APS patients, due to their predictable anticoagulant effects and fewer drug interactions 2.
• However, a 2019 study warned against the use of DOACs, including apixaban, in triple-positive APS patients, citing an increased risk of thromboembolic events compared to warfarin 3.
• A 2022 case series evaluated the safety and effectiveness of apixaban in APS patients and found that while some patients tolerated the medication, others experienced recurrent venous thromboembolism and bleeding complications 4.
• A systematic review of international guidelines on the use of DOACs in APS patients found that most guidelines recommend against their use, except in specific cases where warfarin is not suitable or effective 5.
• The current management of APS emphasizes the importance of anticoagulation, but also acknowledges the limitations and potential risks of available treatments, including DOACs like apixaban 6.

Key Considerations for Eliquis Use in APS

• Patient-specific factors, such as the presence of triple positivity, arterial thrombosis, or previous thromboembolic events, may influence the decision to use apixaban in APS patients 3, 4, 5.
• The potential benefits and risks of apixaban in APS patients must be carefully weighed, taking into account the individual patient's clinical profile and medical history 2, 4, 5.
• Further research is needed to fully understand the safety and effectiveness of apixaban in APS patients and to inform evidence-based treatment guidelines 3, 4, 5.
