Abstract
Purpose
Considerable interest has been focused on angiogenic factors and angiogenic imbalance in the field of pre-eclampsia (PE), owing to its gaining role in the development of PE. This study was addressed to investigate the associations of sFlt-1-to-PlGF plasma ratios with oxidative stress assessed by the level of 8-isoprostane, and inflammation measured by the level of high-sensitive C-reactive protein (hs-CRP), and adipocytokines.
Methods
A total of 83 patients with PE including 47 mild PE (MPE) and 36 severe PE (SPE) and 50 age-matched normotensive subjects in the third trimester of pregnancy were examined. Measurements included body mass index (BMI), systolic and diastolic blood pressure (BP) levels, plasma concentrations of hs-CRP, 8-isoprostane, adiponectin, and leptin.
Results
Subjects with PE had higher levels of sFlt-1/PlGF (P < 0.01), hs-CRP (P < 0.01), 8-isoprostane and leptin (both P < 0.01) and lower adiponectin (P < 0.01) than did normotensive control subjects. Significant positive correlations were found between plasma sFlt-1/PlGF and hs-CRP (r = 0.437, P < 0.01) or leptin (r = 0.656, P < 0.01). A weak inverse correlation emerged between sFlt-1/PlGF and adiponectin (r = −0.306, P < 0.01). When a multiple regression analysis was performed, with sFlt-1/PlGF as a dependent variable and all the other parameters as independent variables, sFlt-1/PlGF maintain a significant relationship with leptin (β = 0.219, P < 0.05) and with hs-CRP (β = 0.295, P < 0.01) as well as with systolic BP(β = 0.446, P < 0.05).
Conclusions
In Chinese preeclamptic women, plasma sFlt-1-to-PlGF ratio is correlated with inflammatory and adipocytokines but not with oxidative stress.
