Severe Preeclampsia versus HELLP Syndrome: Maternal and Perinatal Outcomes at <34 and ≥34 Weeks’ Gestation

Background: Preeclampsia and Hemolysis, Elevated Liver enzymes, Low Platelet (HELLP) syndrome are important disorders affecting the health of both the mother and fetus. Prediction of the maternal and perinatal outcomes at early and late gestational age is important for the management of both disorders. Aims: The purpose of the study was to investigate adverse maternal and perinatal outcomes in severe preeclampsia and HELLP syndrome cases according to gestational age. Study Design: Retrospective cross-sectional study. Methods: One hundred and ninety-seven pregnancies with severe preeclampsia and 56 pregnancies with HELLP syndrome were included the study. Clinical characteristics and adverse maternal and perinatal outcomes were noted from medical records. Participants were divided into two groups at <34 and ≥34 weeks’ gestation: the severe preeclampsia group and the HELLP syndrome group. The differences between the outcomes in the groups were investigated. Statistical analysis was performed using the Student t test, Fisher Exact test and Yates’ Chi-square test. Results: Eclampsia was more common in HELLP syndrome cases at
