Amyloidosis Awareness Video Antiphospholipid Syndrome Antiphospholipid syndrome (APS), also known as Hughes syndrome for the British rheumatologist who first described the syndrome in 1983, is an autoimmune blood clotting disorder. Patients usually present with progressive bilateral and symmetrical muscle weakness accompanied by mild sensory symptoms, including paresthesia, numbness, and tingling. The SWISS PROT protein database revealed high homology between the hexapeptides that bind to ILA-1, ILA-3, and H-3 mAbs and the membrane particles of different bacteria and viruses. Pregnancy is a risk factor for deep venous thrombosis, and risk is further increased with a personal or family history of thrombosis or thrombophilia. These fascinating results suggest that the use of synthetic peptides that focus on neutralization of pathogenic anti-b2GPI antibodies represents a possible new therapeutic approach to APS.

Unfortunately, it’s often only diagnosed after a person has had a number of miscarriages, or blood clots in their arteries, veins or brain. Antiphospholipid antibody syndrome is an autoimmune disorder in which the body's immune system makes antibodies that attack phospholipids, causing cell damage and blood clots. Am J Obstet Gynecol.
