INTRODUCTION: Women with a history of preeclampsia have a higher risk of recurrent preeclampsia. This study sought to ascertain the relationship between the interbirth interval and the risk of recurrent preeclampsia and difference in angiogenic markers between the two groups.
METHODS: Data was collected from an ongoing cohort study of women with hypertensive disorders of pregnancy (HDP) enrolled at the admission to the labor and delivery floor. From this dataset, multigravida women with a prior diagnosis of preeclampsia were identified and compared to women with no prior history of preeclampsia.
RESULTS: Of the 375 women with HDP who were predominantly African American, 245 were multigravida and 44 (18.0%) had a prior history of preeclampsia. Women with prior preeclampsia had an earlier gestational age of delivery, higher rates of preterm delivery and a higher incidence of preeclampsia with severe features (56.8% vs 29.8%) in the index pregnancy (p-values ≤ 0.001) than those without. The median number of years between history of preeclampsia in previous pregnancy and current pregnancy was 6 years (IQR 3, 8). Among patients with a prior history of preeclampsia, the interbirth interval was not associated with severe preeclampsia (p = 0.60) and there was no difference in angiogenic factors between patients with a prior history of preeclampsia compared to those without.
CONCLUSIONS: In this study, the duration of the interbirth interval was not identified as a risk factor of developing severe preeclampsia in a subsequent pregnancy and angiogenic factors are not a reflection of maternal predisposition to recurrent preeclampsia.
