PY - 2020 T2 - Current Medical Diagnosis and Treatment 2020 AB - The antiphospholipid syndrome (APS) is characterized by the presence of specific autoantibodies in association with certain clinical conditions, most notably arterial and venous thrombosis and adverse pregnancy outcomes. Clinically, the diagnosis can be suspected after any of the following outcomes: an episode of thrombosis, three or more unexplained consecutive spontaneous abortions prior to 10 weeks’ gestation, one or more unexplained deaths of a morphologically normal fetus after 10 weeks’ gestation, or a preterm delivery at less than 34 weeks due to preeclampsia or placental insufficiency. In addition to these clinical features, laboratory criteria include the identification of at least one of the following three antiphospholipid antibodies: (1) anticardiolipin antibodies, (2) anti-beta-2-glycoprotein I antibodies, or (3) the lupus anticoagulant (see Chapter 20-09).
