Chromogenic factor X-guided warfarin monitoring in lupus anticoagulant-positive primary antiphospholipid syndrome with adrenal hemorrhage and progressive deep vein thrombosis: a case report

Abstract Background Antiphospholipid syndrome (APS) is a thrombotic autoimmune disorder; adrenal hemorrhage is uncommon. Treating progressive thrombosis with concurrent major bleeding is challenging, especially when lupus anticoagulant (LA) may compromise international normalized ratio (INR)-based warfarin monitoring.
