Abstract
OBJECTIVE
To analyze if sFlt-1/PlGF ratio is more useful than other parameters at diagnosis of early-onset (<34 weeks) preeclampsia (PE) in the prediction of delivery within 48 h and adverse maternal and perinatal outcomes.
METHOD
Observational retrospective study of a cohort of 76 singleton pregnancies with early-onset PE and expectant management. The predictive value of sFlt-1/PlGF ratio, blood pressure, proteinuria, creatinine, liver enzymes and platelets at diagnosis for delivery < 48 h and adverse outcomes was determined.
RESULTS
Maternal and perinatal adverse outcomes occurred in 25/76 (32.9%) cases and 13/69 (18.8%) livebirths, respectively. Areas under the curve (AUC) for sFlt-1/PlGF ratio were 0.59 (95%CI 0.42-0.75) and 0.75 (95%CI 0.62-0.88) for maternal and perinatal complications, respectively. Mean (standard deviation) time to delivery for a sFlt-1/PlGF ratio > 655 vs. ≤ 655 was of 4.4 (7.5) vs. 12.1 (9.3) days, p < 0.01. Relative risk for delivery within 48 h for a sFlt-1/PlGF ratio > 655 was 5.3 (95% confidence interval 2.7-10.6), p < 0.01.
CONCLUSIONS
sFlt-1/PlGF ratio > 655 at diagnosis was associated with a 5-fold increased risk of delivery in ≤ 48 h. None of the parameters were good predictors of adverse maternal or perinatal outcomes.
