Antiphospholipid syndrome is known for causing arterial or venous blood clots, in any organ system, and pregnancy-related complications.While blood clots and pregnancy complications are the most common and diagnostic symptoms associated with APS, other organs and body parts may be affected like platelet levels, heart, kidneys, brain, and skin.
Positive laboratory test results should be seen on two occasions at least 12 weeks apart in order for diagnosis. Antiphospholipid antibody syndrome is an important marker for recurrent thrombosis, and often warrants indefinite anticoagulant (blood thinner) therapy. Warfarin appears to be preferable to DOACs as the latter have recently been ...
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).

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 .
Those with antiphospholipid syndrome may be offered long-term anticoagulation after a first unprovoked episode of thrombosis. The risk is determined by the subtype of antibody detected, by the antibody titer (amount of antibodies), whether multiple antibodies are detected, and whether it is detected repeatedly or only on a single occasion.
Immunofluorescence pattern of SS-A and SS-B antibodies. Produced using serum from a patient on HEp-20-10 cells with a FITC conjugate. Anti-SSA autoantibodies (anti–Sjögren's-syndrome-related antigen A autoantibodies, also called anti-Ro, or similar names including anti-SSA/Ro, anti-Ro/SSA, anti–SS-A/Ro, and anti-Ro/SS-A) are a type of anti-nuclear autoantibodies that are associated with ...
There are no diagnostic tests on which all Sneddon's patients will have abnormal results, although brain MRI and skin biopsy are often abnormal. The diagnosis is based on a detailed history and physical examination. About 40-60% of patients with the syndrome test positive for antiphospholipid antibodies. [citation needed]
