The sFlt-1/PlGF ratio is a useful indicator in predicting adverse pregnancy outcomes in preeclampsia. The high-risk group had lower gestational weeks, lighter neonatal weight, and longer stay in the neonatal intensive care unit compared to the low-risk group.
Objective: Preeclampsia is clinically unpredictable and associated with adverse outcomes. Pregnant women with suspected preeclampsia require intensive monitoring or hospitalization for elevated sFlt-1 (soluble fms-like tyrosine kinase-1) to PlGF (placental growth factor) ratios before symptoms arise. We aimed to determine the sFlt-1/PlGF ratio's usefulness in predicting adverse pregnancy outcomes in preeclampsia. Methods: From January 2017 to February 2019, we measured the sFlt-1/PlGF ratio in 73 singleton pregnant women suspected of preeclampsia and classified them into three groups: low-risk (sFlt-1/PlGF ratio < 38, n = 19), intermediate (38 <= ratio < 85, n = 9), and high-risk (ratio >= 85, n = 32). Results: Although the low- and high-risk groups both experienced weight gain during pregnancy, their body mass index (BMI) differed after pregnancy (p = 0.004). The number of women who had been taking antihypertensive medications for chronic hypertension since early pregnancy was higher in the low-risk group (31.6% vs. 22.2%, 6.7%). The gestational weeks at birth were lower in the high-risk group compared to that of the low-risk group (32.0 weeks vs. 35.79 weeks, p < 0.001). In the high-risk group, the average neonatal weight was significantly lighter (p = 0.021), and the period of stay in the neonatal intensive care unit was longer than that in the low-risk group (p = 0.003). Conclusion: The sFlt-1/PlGF ratio is a useful indicator of preeclampsia severity and can be utilized as a prognostic marker.
