Managing antiphospholipid syndrome in pregnancy

摘要

Antiphospholipid syndrome (APS) is an autoimmune disease characterised by the presence of antiphospholipid antibodies (aPL). The antibodies currently included in the classification criteria include lupus anticoagulant (LA), anticardiolipin antibodies (aCL) and anti-beta 2-glycoprotein 1 antibodies (beta 2GPI). APS can present with a variety of clinical phenotypes, including thrombosis in the veins, arteries and microvasculature and obstetrical complications. Pregnancy complications in obstetric APS (OAPS) include unexplained recurrent early pregnancy loss, fetal death, or premature birth due to severe preeclampsia, eclampsia, intrauterine growth restriction or other consequences of placental insufficiency. Careful, well monitored obstetric care with the use of aspirin and heparin has likely improved the pregnancy outcome in obstetric APS and currently approximately 70-80% of pregnant women with APS have a successful pregnancy outcome. However, the current standard of care does not prevent all pregnancy complications as the current treatment fails in 20-30% of APS pregnancies. Other treatments options arc currently being explored and retrospective studies suggest that trials with hydroxychloroquine and possibly pravastatin are warranted in pregnant women with aPL. In this review will focus on the current treatment of OAPS.
