Systemic lupus erythematosus: obstetric and neonatal implications.

Systemic lupus erythematosus (SLE) is a collagen vascular disease that may have a tremendous impact on pregnancy. The pregnant patient with SLE is at increased risk for fetal wastage, intrauterine growth retardation (IUGR), intrauterine fetal demise (IUFD), pregnancy-induced hypertension (PIH), and exacerbations of the lupus process. SLE is an autoimmune disease with tremendous implications for pregnancy. The diagnosis of SLE is based on criteria developed by The American Rheumatism Association. The recent identification of circulating antibodies associated with women who have lupus has led to some confusion. The circulating antibodies are associated with an increased risk of fetal wastage. However, those antibodies have been documented in women who do not have lupus. The diagnosis of SLE and pregnancy requires intensive obstetrical care. SLE may also affect the neonate, from skin lesions to complete heart block. This article describes the effects of SLE on the mother, pregnancy, and the neonate.
