<prompt> Answer this question truthfullyWhat does Antiphospholipid Syndrome mean?  <response>: <reason> Antiphospholipid syndrome APS is an autoimmune disease in which antiphospholipid antibodies anti-cardiolipin antibodies and lupus anticoagulant react against proteins that bind to anionic phospholipids on plasma membranes. This syndrome can be classified into primary no underlying disease state and secondary in association with an underlying disease state types. The underlying mechanism of APS mediated by the antibodies is mainly mediated via their affect on the coagulation cascade which subsequenlty leads to increased vascular tone of thrombosis. CAPS is a subclass of APS that results in development of a catastrophic illness characterized by progressive, severe arterial and venous thrombosis in multiple organs, often leading to death.
