Management of pregnant women with antiphospholipid antibodies

Important advancements in pregnancy outcome have been reported in women with antiphospholipid antibodies (aPL), despite the fact that the treatment of aPL related pregnancy morbidity is not guided by consistent findings from well-designed trials. Areas covered: The current study draws a picture of the studies in the literature by performing a Medline search of relevant English language articles and reports our experience in managing different subsets of obstetric antiphospholipid syndrome (APS), defined on the basis of their clinical and laboratory characteristics. The management of pregnant women with non-criteria APS manifestations and that of aPL carriers during their first pregnancy is also examined. Expert commentary: A heparin/aspirin combination constitutes conventional treatment for APS affected pregnant women. As this strategy fails in approximately 20-30% of cases, uncovering other options for women refractory to conventional treatment or at high risk of pregnancy complications has become an urgent undertaking. Some attempts have been made to prescribe additional treatments in the effort to improve live birth rates and/or reduce pregnancy complications, which often occur even in patients treated conventionally. The evidence from some studies and an individual risk/benefit assessment should instead guide treatment decisions for pregnant patients with non-criteria APS manifestations and aPL carriers.
