Antiphospholipid syndrome, or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by antiphospholipid antibodies.APS can lead to blood clots in both arteries and veins, pregnancy-related complications, and other symptoms like low platelets, kidney disease, heart disease, and rash.
An increase in the prevalence of antiphospholipid antibodies (known as antiphospholipid syndrome) can be found in many recurrent miscarriage patients. However, there is no evidence that the increase in antiphospholipid antibodies harms the pregnancy, but is thought to be indicative of immune dysfunction and proinflammatory responses in regards ...
Antibodies against phosphatidylserine and phosphatidylethanolamine are against the trophoblast. [16] These phospholipids are essential in enabling the cells of the fetus to remain attached to the cells of the uterus with implantation. If a female has antibodies against these phospholipids, they will be destroyed through the immune response and ...
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 ...
Among other causes of hypercoagulability, Antiphospholipid syndrome has been associated with adverse pregnancy outcomes including recurrent miscarriage. [8] Deep vein thrombosis has an incidence of one in 1,000 to 2,000 pregnancies in the United States, [ 2 ] and is the second most common cause of maternal death in developed countries after ...
Antiphospholipid syndrome: The antiphospholipid syndrome is an autoimmune disease that is a common cause of recurrent pregnancy loss. [ 34 ] [ 15 ] Around 15% of the women who have recurrent miscarriages have high levels of antiphospholipid antibodies. [ 34 ]
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 .
[13] [14] [5] [4] [2] [15] Pregnancy [7] and ethinylestradiol (EE)-containing combined birth control pills increase APC resistance as measured by either the aPTT- or ETP-based test. [ 4 ] [ 5 ] [ 15 ] EE-containing birth control pills show different degrees of influence on the ETP-based test depending on the progestin , which may be due to ...
