Les issues périnatales des femmes avec prééclampsie récidivante : une étude rétrospective
OBJECTIVE: To assess whether a recurrent preeclampsia compared to the preeclampsia that occurred at the first pregnancy was more at risk of preterm delivery at < 37 weeks of gestation. Secondary outcomes were intrauterine growth restriction (IUGR) and maternal morbidity.  STUDY DESIGN: We conducted a retrospective cohort study including 383 women with preeclampsia who delivered at Sainte-Justine Hospital in Montreal (Canada) from 2001 to 2011. Among these, 128 women developed a recurrent preeclampsia in their subsequent pregnancy.   RESULTS: Among women with a recurrent preeclampsia (n = 128), no significant differences were found in the rates of preterm delivery and IUGR between the first and the subsequent pregnancy. Women with a recurrent preeclampsia were more at risk of chronic hypertension (p = 0.001) and gestational diabetes (p = 0.02) in their second pregnancy. Furthermore, women with recurrent preeclampsia had, at their first pregnancy, a higher rate of severe preeclampsia (p < 0.001), eclampsia and adverse criteria (p = 0.007), than women who experienced a single preeclampsia (n = 255). The Relative Risk to experience a recurrent preeclampsia at the second pregnancy, if a woman had the above criteria at the first pregnancy, was 1.60 (95%CI 1.17 - 2.18).  CONCLUSION: Recurrent preeclampsia was not associated with a higher rate of preterm delivery. Women who experienced a severe preeclampsia, an eclampsia or adverse criteria in a first pregnancy were more at risk to have a recurrent preeclampsia in the subsequent pregnancy.
