Antiphospholipid Antibodies in Pregnancy

Summary: We assessed the relationship between antiphospholipid antibodies and recurrent miscarriage, fetal deaths, and the pregnancy complications ‐ placental abruption, fetal growth retardation and preeclampsia. The subjects were 81 women with a history of 3 or more miscarriages, 62 with a history of fetal death in the index pregnancy, 105 with a poor obstetric history or pregnancy complications and 13 with systemic lupus erythematosus. Antiphospholipid antibodies were found in 41% of women with a history of recurrent miscarriages, 29% with a history of recent intermediate fetal death or stillbirth, 19% with a poor obstetric history and 69% with systemic lupus erythematosus. There is a high incidence of antiphospholipid antibodies in complicated pregnancies. Patients presenting with the above pregnancy disorders should be tested for antiphospholipid antibodies because of the risk conferred on a fetus by their presence and to expand the treatment options.
