Objectives Early onset pre-eclampsia (PE) is considered a worse disorder than later onset PE for the baby but differences in maternal outcomes are less certain. Aims To compare maternal and fetal outcomes amongst women with early onset PE (EOP) 37 weeks. Methods We retrospectively analysed outcomes of women with hypertension in pregnancy from our data that is collected during admission and validated by a physician at discharge. Between 1991 and 2011, 4657 pregnancies were complicated by hypertension; 2148 (45%) had pre-eclampsia. 1536 (72%) of these cases had complete data. Results 291 (19%) had EOP; 505 (33%) pre-term PE and 740 (48%) term PE. Maternal age was similar. Women with pre-term and term onset PE had similar maternal and fetal outcomes. Compared with term PE, women with EOP had similar rates of renal impairment (7% vs. 9%), proteinuria (76% vs. 81%), liver dysfunction (17% vs. 13%), thrombocytopenia (4.5% vs. 5%) and eclampsia (3 vs. 9/1000), but more episodes of severe hypertension (45% vs. 31%, p p p p p p Conclusions Women presenting with PE after 34 weeks have generally good maternal and fetal outcomes. Women with EOP are more likely to have severe hypertension and neurological symptoms but otherwise similar rates of other maternal complications as women with term PE. Outcomes for babies of women with EOP are significantly worse. These data highlight the fact that pre-eclampsia at any gestation poses fairly similar risks for the mother but EOP poses much greater risks for the baby. Disclosures F.M. Pettit: None. G.J.
