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.
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 .
Current evidence suggests that the risk of recurrent thrombosis in patients with an antiphospholipid antibody is enhanced whether that antibody is measured on serological testing or functional testing. The Sapporo criteria specify that both serological and functional tests must be positive to diagnose the antiphospholipid antibody syndrome. [21]
Human Chr 3. In terms of the cause of protein S deficiency it can be in inherited via autosomal dominance.A mutation in the PROS1 gene triggers the condition. The cytogenetic location of the gene in question is chromosome 3, specifically 3q11.1 [6] [7] Protein S deficiency can also be acquired due to vitamin K deficiency, treatment with warfarin, liver disease, kidney disease, chemotherapy ...
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). [4]
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 ...
Antiphospholipid syndrome was described in full in the 1980s, after various previous reports of specific antibodies in people with systemic lupus erythematosus and thrombosis. [18] [49] The syndrome is often attributed to the British rheumatologist Graham R.V. Hughes, and is often referred to as Hughes syndrome for that reason. [50]
Libman–Sacks endocarditis is a form of non-bacterial endocarditis that is seen in association with systemic lupus erythematosus, antiphospholipid syndrome, and malignancies. It is one of the most common cardiac manifestations of lupus (the most common being pericarditis). [1] [2]
