Systemic lupus erythematosus (SLE) predominantly affects younger women, and so the question of lupus and pregnancy may arise frequently in clinical practice. Patients with SLE have an increased incidence of spontaneous aboion, fetal death in utero, and prematurity. The mother may experience an exacerbation in the activity of her disease in the third trimester or peripaum period, and it may be difficult to distinguish between active SLE and preeclampsia. Therapy of pregnant patients with SLE is problematic, and the generalist should consult the literature or a specialist when such a patient is encountered.Congenital malformations (choices B, C, and D) are not a complication of pregnancies in patients with SLE.
