Pregnancy in patients with systemic lupus erythematosus

We reviewed the obstetrical performance and outcome of 15 pregnancies in patients with systemic lupus erythematosus (SLE) (study group) and compared them with 45 age and parity-matched normal pregnancies (control group). Eleven women (73.8%) were in remission phase and 4 (26.7%) had active disease at the time of conception. The time interval between disease diagnosis and the index pregnancy was 4.2 +/- 2.5 years. Two patients with renal involvement had lupus flare-up during the antenatal period. There was no case of lupus flare-up in the postpartum period. Gestational age at delivery was significantly lower in SLE patients (35.9 +/- 2.5 weeks) compared to the control group (37.4 +/- 2.2 weeks). The incidence of intrauterine growth retardation was significantly higher in the SLE patients (40%), There was no case of neonatal lupus or congenital heart block.
