[Systemic lupus erythematosus during pregnancy].

Systemic lupus erythematosus (SLE) is a connective tissue disease most commonly affecting women of a fertile age. It is recommended that pregnancy is planned during periods with remission or low activity of he disease because it seems that SLE is more likely to be exacerbated by pregnancy when the disease is active at the time of conception. Presence of circulating anti-phospholipid antibodies is associated with a poor prognostic outcome for the foetus and increases the risk of complications related to pregnancy.
