lupus and antiphospholipid antibody syndrome

overview

about 1 out of 3 people with lupus produce an antibody that attacks certain blood-clotting factors, which can cause the blood to clot easily.^{footnote 1} a person who has this antibody and has had blood clots is said to have antiphospholipid antibody syndrome. this can lead to mild or severe blood-clotting complications, including:

stroke, transient ischemic attack (tia), or heart attack.
deep vein thrombosis or pulmonary embolism.
multi-infarct dementia.
gangrene of fingers or toes.
kidney disease.
pre-eclampsia, premature birth, and miscarriage or stillbirth, apparently caused by blood circulation problems in the placenta.

a blood test can detect antiphospholipid antibodies. when diagnosed, the condition is usually treated with anticoagulants. pregnant women with antiphospholipid antibody syndrome need to be closely monitored.
