Resumo: | Abstract Preeclampsia (PE) is a significant gestational disorder that causes complications in 3- 5% of all human pregnancies. Apart from the immediate risks and complications for mother and fetus, both additionally carry elevated lifelong risks for specific complications. Offspring of PE pregnancies (PE-F1) have higher risks for hypertension, stroke and cognitive impairment compared with well-matched offspring (F1) fromuncomplicated pregnancies. Prior to the clinical onset of PE, placental angiokines secreted into the maternal plasma are deviated. In many PE patients this includes deficits in placental growth factor (PGF). Our laboratory found that mice genetically-deleted for PGF (PGF - / -) have altered cerebrovascular and brain neurological development detectable from midgestation to adulthood. We hypothesized that the PGF deficits seen in human PE, deviate fetal cerebrovascular and neurological development in a manner that impairs cognitive functions and elevates stroke risk. Here we summarize the initial analytical outcomes from a pilot study of 8-10 year old male and female PE-F1s and matched controls. Our studies were the first to report magnetic resonance imaging (MRI), magnetic resonance angiography (MRA) and functional brain region assessment by eyemovement control and clinical psychometric testing in PE-F1s. Further studies in larger cohorts are essential to define whether there are image-based biomarkers that describe unique anatomical features in PE-F1 brains. |
