Antiphospholipid syndrome is characterised by all EXCEPT
Correct Answer: Hypocoagulable
Description: (A) Hypocoagulable # Antiphospholipid syndrome (APS or APLS) or antiphospholipid antibody syndrome is a disorder of coagulation that causes blood clots (thrombosis) in both arteries and veins as well as pregnancy-related complications such as miscarriage, stillbirth, preterm delivery, or severe preeclampsia. The syndrome occurs due to the autoimmune production of antibodies against phospholipid (aPL), a cell membrane substance.> In particular, the disease is characterized by antibodies against cardiolipin (anti-cardiolipin antibodies) & b2 glycoprotein I.> Antiphospholipid syndrome can cause (arterial/venous) blood clots (in any organ system) or pregnancy-related complications. In APS patients, the most common venous event is deep vein thrombosis of the lower extremities (blood clot of the deep veins of the legs) and the most common arterial event is stroke. In pregnant women affected by APS, miscarriage can occur prior to 20 week of gestation, while pre-eclampsia is reported to occur after that time.> Placental infarctions, early deliveries and stillbirth are also reported in women with APS. In some cases, APS seems to be the leading cause of mental and/or development retardation in the newborn, due to an aPL-induced inhibition of trophoblast differentiation.> Other common findings, although not part of the APS classification criteria, are thrombocytopenia (low platelet count), heart valve disease, and livedo reticularis (a skin condition). Some patients report headaches, migraines, and oscillopsia.> Very few patients with primary APS go on to develop SLE.
