Objective We examined whether maternal serum cytokine profiles of mothers with early‐onset fetal growth restriction (FGR) were associated with delivery within 2 weeks after sampling during the third trimester. Study design This exploratory prospective cross‐sectional study included a total of 20 singleton fetuses with early‐onset FGR and 31 healthy controls. Maternal serum samples during the early third trimester were analyzed for 23 cytokines. Results Of 20 fetuses with early‐onset FGR, 14 had delivery within 2 weeks after sampling. Multivariate analysis revealed that maternal serum concentrations of soluble vascular endothelial growth factor receptor‐1 (sVEGFR‐1) and soluble CD40 ligand (sCD40L) were independently associated with delivery within 2 weeks in early‐onset FGR. Among cases of early‐onset FGR, concentrations of almost all maternal serum cytokines were similar. Maternal serum sVEGFR‐1 concentrations were high when delivery occurred within 2 weeks. Maternal serum sCD40L concentrations were elicited only in cases in which delivery within 2 weeks occurred due to fetal deterioration. Conclusion We identified two biomarkers, one specific for FGR and the other dependent on severity, that were significant components of angiogenic activities and inflammation factors. Imbalances in serum protein expression may have a substantial effect on the pathogenesis of FGR.
