Introduction: The renin-angiotensin system (RAS) become upregulated very early on in pregnancy and is crucial in maintaining blood pressure. In addition to the peripheral RAS there is a uteroplacental RAS, which is also important in regulating placental function and development. Recent work has shown extra-renal sodium storage in the skin; it is suggested that the placenta may also function as a salt sensing organ and is important in regulating maternal blood pressure.<p c...

Background: Aldosterone levels are elevated in normal pregnancy but fall despite volume contraction in preeclampsia. Vascular endothelial growth factor (VEGF) and soluble fms-like tyrosine kinase 1 (sFlt-1) have been implicated in this phenomenon in vitro and in animal work. Low placental growth factor (PlGF), which is closely linked to VEGF signalling, identifies women at risk of preeclampsia between 20 and 35 weeks gestation. We aimed to examine these relationships ...
