Antiphospholipid Syndrome
(APS) is an autoimmune illness in which the body's immune
system wrongly creates antibodies that raise the risk of abnormal blood clot
development in arteries and veins. These clots can cause major
consequences, such as deep vein thrombosis, pulmonary embolism, stroke, or
heart attack. It is also an important cause of recurrent pregnancy loss,
stillbirth, preterm delivery, and pregnancy-associated problems. It may
be isolated (primary APS) or associated with other autoimmune illnesses,
including systemic lupus erythematosus (SLE). Issues vary depending on
where the clot is located and may include leg discomfort and swelling, chest
pain, shortness of breath, neurological issues, or pregnancy loss. Diagnosis is
based on a combination of clinical history and blood tests to detect antiphospholipid
antibodies, including lupus anticoagulant, anticardiolipin antibodies,
and anti-beta-2 glycoprotein I antibodies.
These antibodies may be transient; therefore, additional testing is
usually necessary after at least 12 weeks to confirm the diagnosis. Treatment
aims to prevent blood clots with anticoagulant drugs such as warfarin or
heparin. Pregnant women are commonly given low-dose aspirin and heparin to
improve pregnancy outcomes. Lifestyle changes, smoking cessation, control of cardiovascular disease risk factors, and frequent medical follow-up can decrease problems
and enhance long-term health. With the right treatment, many people with APS can
live busy and healthy lives.
