Those with APS make abnormal proteins called antiphospholipid autoantibodies in the blood. This causes blood to flow improperly and can lead to dangerous clotting in arteries and veins, problems for a developing fetus and pregnancy miscarriage.

Prior research has proposed the decreased dilation in APS patients may be the result of reduced nitric oxide bioavailability. The preservation of endothelial nitric oxide function requires, among other things, the bioavailability of tetrahydrobiopterin. APS is a blood disorder where your body accidentally attacks normal proteins in the blood, which are made to control blood clotting. A person with APS has antiphospholipid antibodies. These antibodies cause blood clots to form. This leads to several complications, including Blood clots in veins DVT deep vein thrombosis Catastrophic antiphospholipid syndrome CAPS is a variant of antiphospholipid syndrome that is characterized by blockage of many blood vessels throughout the body. As a result of catastrophic antiphospholipid syndrome, many organs can be affected, including the skin, lungs, brain, heart, kidneys, and bowels. APS affects women five times more commonly than men. People with this disorder may otherwise be healthy, or they also may suffer from an underlying disease, most frequently systemic lupus erythematosus (commonly called lupus or SLE).

Like other antibodies involved in lupus that are directed against self auto-antibodies, antiphospholipid antibodies can come and go or increase and decrease.

Antiphospholipid antibodies are a group of immune proteins that the body mistakenly produces against itself in an autoimmune response to phospholipids. Tests can detect these autoantibodies that bind to phospholipids and, in a way that is not well understood, increase the risk of excessive blood clotting. Antiphospholipid antibodies are present in 15 - 20% of all cases of deep vein thrombosis blood clots and in one-third of new strokes occurring in people under the age of 50. Antiphospholipid antibodies are a major cause of recurrent miscarriages and pregnancy complications when no other causes are found. To receive a diagnosis of APS, patients must test serologically positive for at least one of the following on two occasions 12 weeks apart anticardiolipin antibodies, anti-beta-2-GPI antibodies aB2GPI and/or lupus anticoagulant. Of these, B2GPI may be the most relevant target of the antiphospholipid antibodies.
