title: Maternal and neonatal outcomes in pregnancies complicated by systemic lupus erythematosus: a population-based study.
abstract: OBJECTIVE
  To determine maternal and neonatal outcomes in pregnancies complicated by systemic lupus erythematosus (SLE).
  
  
  METHODS
  In a retrospective cohort study using the Nova Scotia Atlee Perinatal Database, 97 pregnancies in women with SLE, with 99 live births, were compared with 211 355 pregnancies in women without SLE and their 214 115 babies. All were delivered in Nova Scotia between 1988 and 2008.
  
  
  RESULTS
  In women with SLE, gestational age at birth and mean neonatal birth weight were lower (P < 0.001) than in women without SLE. On bivariate analysis, severe preeclampsia, Caesarean section, newborn resuscitation for > 3 minutes, respiratory distress syndrome, assisted ventilation, bronchopulmonary dysplasia, patent ductus arteriosus, mild to moderate intraventricular hemorrhage, retinopathy of prematurity, and congenital heart block in neonates were significantly more frequent in the women with SLE. Logistic regression analysis identified that having SLE increased the risks of Caesarean section (OR 1.8; 95% CI 1.1 to 2.8, P = 0.005), postpartum hemorrhage (OR 2.4; 95% CI 1.3 to 4.3, P = 0.003), need for blood transfusion (OR 6.9; 95% CI 2.7 to 17, P = 0.001), postpartum fever (OR 3.2; 95% CI 1.7 to 6.1, P = 0.032), small for gestational age babies (OR 1.7; 95% CI 1.005 to 2.9, P = 0.047), and gestational age ≤ 37 weeks (OR 2.1; 95% CI 1.3 to 3.4, P = 0.001). Neonatal death was not shown to be more common in women with SLE (RR 3.05; CI 0.43 to 21.44, P = 0.28).
  
  
  CONCLUSIONS
  Mothers with SLE have an increased risk of Caesarean section, postpartum hemorrhage, and blood transfusion. They are more likely to deliver premature babies, smaller babies, and babies with congenital heart block.
