Antiphospholipid Syndrome (APS)
Overview
Autoantibodies damage proteins that are attached to fat molecules (phospholipids) causing blood clots to form in the body’s arteries and veins and making the blood “stickier” than normal. This is dangerous because it causes an increased risk of abnormal blood clotting. APS is a systemic autoimmune disorder characterized by an increased risk for arterial, venous and/or microvascular thrombosis and various obstetric complications.
Common Symptoms
Chest pain and shortness of breath, pain, and swelling in the limbs, chronic headaches, speech changes, net-like rashes, upper body discomfort, nausea, and stroke.
Coexisting Diseases and Conditions
Lupus, cardiovascular diseases, cerebrovascular diseases, rheumatoid arthritis, Sjögren’s syndrome, autoimmune hepatitis, systemic scleroderma, thrombosis, kidney damage, and miscarriages.
Risk Factors and Prevalence
Sex may be a possible risk factor given that APS has been shown to affect females 3 to 5 times more than males; other autoimmune disorders such as lupus, and infections. The use of certain medications such as hydralazine (blood pressure), quinidine, Dilantin (anti-seizure), and amoxicillin are other risk factors.
