being diagnosed as positive. Antiphospholipid syndrome, or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by antiphospholipid antibodies.APS provokes blood clots in both arteries and veins as well as pregnancy-related complications such as miscarriage, stillbirth, preterm delivery, and severe preeclampsia.The diagnostic criteria require one clinical event (i.e. It is not required to perform the test due to a drug, infection, or without any symptoms. NICE Guidance International Journal of Biomedical Research, 2014. The two antibodies implicated are anticardiolipin and lupus anticoagulant. In APS patients, the most common venous event is deep vein thrombosis of the lower extremities, and the most common arterial event is stroke. In pregnant women affected by APS, there is an increased risk of recurrent miscarriage, intrauterine growth restriction, and preterm birth. Antiphospholipid antibodies. US National Guidelines Clearinghouse. PDF. This means people with APS are at greater risk of developing conditions such as: [12]. Antiphospholipid syndrome (APS) is an autoimmune disorder.Signs and symptoms vary, but may include blood clots, miscarriage, rash, chronic headaches, dementia, and seizures. A historical name for this measure is the kaolin-cephalin clotting time (KCCT), reflecting kaolin and cephalin as materials historically used in the test. APS occurs when your body's immune system makes antibodies that attack phospholipids. [ citation needed ], Distinguishing a lupus antibody from a specific coagulation factor inhibitor (e.g. Clinically important antiphospholipid antibodies (those that arise as a result of the autoimmune process) are associated with thrombosis and vascular disease. Antiphospholipid antibodies. Thrombophilia is an abnormality of blood coagulation that increases the risk of thrombosis. APS occurs when your body's immune system makes antibodies that attack phospholipids. Like many autoimmune diseases, it is more common in women than in men. APS ACTION (the AntiPhospholipid Syndrome Alliance for Clinical Trials and InternatiOnal Networking), is the first-ever international research network that has been created to design and conduct large-scale, multicenter clinical trials in persistently antiphospholipid antibody (aPL) positive patients. The syndrome occurs because of the production of antibodies against phosphilipids. Images. Halaman ini terakhir diubah pada 25 Januari 2017, pukul 04.03. Prononciation de Antiphospholipid syndrome à 1 prononciation audio, 1 sens, et de plus pour Antiphospholipid syndrome. Sering disebut juga sebagai … Symptoms vary between people and may be mild to severe. They are used to determine the clotting tendency of blood, in the measure of warfarin dosage, liver damage, and vitamin K status. Antibodies against prothrombin are detected by enzyme immunoassays (EIA) in sera of patients with antiphospholipid syndrome (APS). Some of them occur naturally in blood-eating animals such as leeches and mosquitoes, where they help keep the bite area unclotted long enough for the animal to obtain some blood. Dalam keadaan normal, antibodi berfungsi baik untuk melawan kuman dan infeksi yang disebabkan virus, akan tetapi kadang-kadang sistem kekebalan tubuh mengalami kerusakan sehingga menyerang tubuh sendiri. [16], The lupus anticoagulant antibodies are those that show the closest association with thrombosis; those that target β2glycoprotein 1 have a greater association with thrombosis than those that target prothrombin. The lupus anticoagulant will inhibit all the contact activation pathway factors (factor VIII, factor IX, factor XI and factor XII). Phospholipids are a type of fat found in all living cells, including blood cells and the lining of blood vessels. Classification with APS requires evidence of both one or more specific, documented clinical events (either a vascular thrombosis and/or adverse obstetric event) and the confirmed presence of a repeated aPL. [ citation needed ]. [11] Cancer is also observed to comorbid in patients with APS. Congress on Antiphospholipid Antibodies, a Task Force on CAPS collected and summarized all these evidences and developed a set of recommendations regarding the diagnosis and treatment of this devastat - ing complication [12]. Antibodi terhadap antifosfolipid juga mengganggu peran pengaturan berbagai faktor dalam sistem pembekuan darah.
