Antiphospholipid syndrome, or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by antiphospholipid antibodies. APS can lead to blood clots ( thrombosis ) in both arteries and veins , pregnancy-related complications , and other symptoms like low platelets, kidney disease , heart disease , and rash .
Catastrophic antiphospholipid syndrome (CAPS), also known as Asherson's syndrome, is a rare autoimmune disease in which widespread, intravascular clotting causes multi-organ failure. [1] The syndrome is caused by antiphospholipid antibodies that target a group of proteins in the body that are associated with phospholipids .
A prominent example is antiphospholipid syndrome, [1] [16] which is caused by antibodies against constituents of the cell membrane, particularly lupus anticoagulant (first found in people with the disease systemic lupus erythematosus but often detected in people without the disease), anti-cardiolipin antibodies, and anti-β 2-glycoprotein 1 ...
Symptoms of pulmonary embolism are typically sudden in onset and may include ... antiphospholipid antibodies, protein C and S and antithrombin levels, and later ...
Approximately 20% of people with SLE have clinically significant levels of antiphospholipid antibodies, which are associated with antiphospholipid syndrome. [135] Antiphospholipid syndrome is also related to the onset of neural lupus symptoms in the brain.
In a suspected antiphospholipid syndrome, lupus anticoagulant is generally tested in conjunction with anti-apolipoprotein antibodies and anti-cardiolipin antibodies, and diagnostic criteria require one clinical event (i.e. thrombosis or pregnancy complication) and two positive blood test results spaced at least three months apart that detect at ...
Schematic representation of antibody. Anti-cardiolipin antibodies (ACA) are antibodies often directed against cardiolipin and found in several diseases, including syphilis, [1] antiphospholipid syndrome, livedoid vasculitis, vertebrobasilar insufficiency, Behçet's syndrome, [2] idiopathic spontaneous abortion, [3] and systemic lupus erythematosus (SLE).

Antiphospholipid antibody syndrome; The treatment of overlapping connective tissue disorders is mainly based on the use of corticosteroids and immunosuppressants. Biologic drugs, i.e. anti-TNFα or anti-CD20 monoclonal antibodies, have been recently introduced as alternative treatments in refractory cases.
