Abstract summary 

To determine if any of maternal pre-delivery soluble fms-like tyrosine kinase-1 (sFlt-1), placental growth factor (PIGF), or sFlt-1/PIGF ratio correlate with either perceived stress scale (PSS) or verbal numeric rating scale (VNRS) pain scores.Among 50 pregnant women with severe pre-eclampsia and 90 normotensive pregnant women observed from 48 h or less before delivery until day 3 postpartum, correlations between the following were performed: (1) serum concentrations of each angiogenic factor (sFlt-1, PIGF, and sFlt-1/PIGF ratio) sampled within 48 h before childbirth and a four-item PSS (pre-delivery and one-off 48-72 h postpartum score); (2) the same angiogenic factors above and VNRS ranging from 0 to 10; and (3) PSS and VNRS (both pre-delivery and postpartum).In the normotensive group, there was a positive correlation between sFlt-1 and postpartum PSS (ρ +0.214 and P = 0.043), and between sFlt-1/PIGF ratio and postpartum PSS (ρ +0.213 and P = 0.044). In the normotensive and severe pre-eclampsia groups there were non-significant negative correlations between PIGF and postpartum PSS (P > 0.096) and non-significant positive correlations between pre-delivery PSS and pre-delivery VNRS (P > 0.053). Other correlations were uninformative.Maternal pre-delivery sFlt-1/PIGF ratio in normotensive pregnancy is a promising biomarker for identifying risk of increased postpartum PSS to enable early counselling.
