Abstract

Objective: To examine whether the maternal serum concentration of the soluble receptor-1 of tumor necrosis factor-α (TNF-R1) at 11-13 + 6 weeks of gestation is a predictor of development of pre-eclampsia (PE).Methods: This is a nested case-control study in which the concentration of TNF-R1 at 11 + 0 to 13 + 6 weeks was measured in 426 pregnant women in the first trimester. TNF-R1 values were expressed as multiples of the median (MoM) adjusted for maternal factors. The distributions of log TNF-R1 MoM in the control group and hypertensive disorders (early-PE [ePE], late-PE [lPE] and gestational hypertension [GH]) groups were compared. Logistic regression analysis was used to determine whether maternal factors, TNF-R1 or their combination make a significant contribution to the prediction of PE. Screening performance was determined by analysis of receiver-operating characteristics curves.Results: Median concentration of TNF-R1 (ng/ml) was higher in ePE (2.62 ± 0.67), lPE (2.12 ± 0.56) and GH (2.19 ± 0.45) compared to controls (2.04 ± 0.42), p = 0.001. Logistic regression analysis demonstrated that the addition of TNFR-1 to maternal factors did not make a significant contribution to the prediction of PE.Conclusions: The maternal serum TNF-R1 concentration at 11-13 + 6 weeks of gestation was increased in pregnancies which developed hypertensive disorders, however, the addition of TNFR-1 did not improve the detection rate of these conditions compared with maternal factors alone.
