Placental Growth Factor (PlGF) associated with compromised Fetal Growth
and Perinatal Outcomes in a High-Risk Pregnancy Population: A
Retrospective Cohort
Abstract
Introduction: Fetal Growth Restriction (FGR) is associated with
placental dysfunction. Placental Growth Factor (PlGF) can help in the
prediction and timely diagnosis of FGR. This study aimed to evaluate the
association between FGR, PlGF, and perinatal outcomes. Methods:
Retrospective cohort of 292 patients. The primary exposure was maternal
PlGF levels. Primary outcomes were fetal growth, abnormal sonographic
placental morphology, preeclampsia, fetal demise (IUFD), preterm birth
(PTB) < 34weeks, low birth weight, neonatal admission to NICU
and placental pathology findings. Results: Normal-grown fetuses
had longer pregnancies when compared to FGR pregnancies. Low PlGF levels
were statistically significant and almost 5-fold higher among
pregnancies with compromised fetal growth. There were 12.5-fold chance
of IUFD in fetuses with compromised growth. Low birthweight was over ten
times higher in growth-restricted fetuses. PTB < 34w and
neonatal admission to NICU were also increased among patients with
compromised fetal growth. Abnormal sonographic placental morphology was
associated with fetal growth restriction. Preeclampsia was not
associated with compromised fetal growth in this cohort. Abnormal
placental pathology was increased 7-fold in growth-restricted fetuses.
Conclusion: PlGF for the management of high-risk cases with
compromised fetal growth is useful. The results confirm that compromised
fetal growth is representative of placental dysfunction, associated with
or without preeclampsia. In this context, PlGF testing has the potential
to improve healthcare outcome in obstetrical care, especially in remote
or low-resource settings.
