Systemic lupus erythematosus (SLE) is the autoimmune disease that most commonly compromises pregnancy. Moreover, the relationship between SLE and pregnancy is in both directions. However, in the recent years there has been a great change in the perception of the effects of pregnancy on SLE flares and of SLE on pregnancy outcome (both fetal and maternal). The current experience indicates that pregnancy in patients with SLE should not be regarded as an unacceptable high risk condition for the mother or her baby provided that careful planning of conception and multidisciplinary monitoring and treatment are carried out.
