Early-onset preeclampsia (EOP), which occurred before 34 weeks, proved to be the deadliest. Indeed, it is characterized by a poor maternal and fetal prognosis. EOP has a disparate incidence in the world varying between 0.9% and 31%. Several risks factors are associated with the occurrence of EOP, which is responsible of several adverse obstetrical outcomes. Complications can affect up to 85% of pregnant women with EOP, especially when EOP appears very early, before 28 or even 25 weeks’ gestation. Objectives: To determine frequency of EOP at the University Clinics of Kinshasa, to describe sociodemographic and clinical characteristics of pregnant women with EOP and to identify its risks factors and its association adverse obstetrical outcomes. Methods: The study will be a cross-sectional analytical study in University Clinics of Kinshasa from January 2016 to December 2022. The minimal size will be 119. Our study population will consist of pregnant women who consult for antenatal best care and are neonates in our Clinic. Result will be presented as percentage proportion. Comparison and proportion means between groups will be made using Student’s test and Pearson’s chi-square test, respectively. Our test will be statistically significant for a p-value ≤ than less 0.05. Data will be collected and analysed anonymously and confidentiality. Conclusion: We believe that our study should enable us to identify profile of gestational carriers at risk of EOP in our environment, as well as prognosis associated with this entity, with a view to arousing particular interest in EOP.展开更多

This study aimed to investigate the clinical definition, features, treatment, outcome and risk factors of early onset severe preeclampsia in Chinese women. Methods Four hundred and thirteen women with severe preeclampsia from June 2006 to June 2009 were divided into three groups according to the gestational age at the onset of preeclampsia as follows： group A （less than 32 weeks, 73 cases）, group B ,（between 32 and 34 weeks, 71 cases）, and group C （greater than 34 weeks, 269 cases）. The demographic characteristics of the subjects, complications, delivery modes and outcome of pregnancy were analyzed retrospectively. Results The systolic blood pressure at admission and the incidence of severe complications were significantly lower in group C than those in groups A and B, prolonged gestational weeks and days of hospitalization were significantly shorter in group C than those in groups A and B. Liver and kidney dysfunction, pleural and peritoneal effusion, placental abruption and postpartum hemorrhage were more likely to occur in group A compared with the other two groups. Twenty-four-hour urine protein levels at admission, intrauterine fetal death and days of hospitalization were risk factors that affected complications of severe preeclampsia. Gestational week at admission and delivery week were also risk factors that affected perinatal outcome. Conclusions Early onset severe preeclampsia should be defined as occurring before 34 weeks, and it is featured by more maternal complications and a worse perinatal prognosis compared with that defined as occurring after 34 weeks. Independent risk factors should be used to tailor the optimized individual treatment plan, to balance both maternal and neonatal safety.展开更多
