ABSTRACT
Objective:To compare the effect of comorbidities on the phenotype and outcomes of preeclampsia.
Methods: A matched retrospective cohort study of women delivering at a tertiary maternity center following a diagnosis of preeclampsia. We collected data on signs and symptoms, biochemical markers, and maternal and perinatal outcomes.
Results:We studied 474 women; 158 women with and 316 without comorbidities. Compared to women without comorbidities, women with comorbidities delivered earlier. They suffered fewer maternal but more neonatal complications.
Conclusion: Women with comorbidities receive earlier intervention than women without comorbidities, which may lead to fewer maternal complications but worse neonatal outcomes.
