Abstract

Purpose

To determine whether maternal serum placental growth factor (PlGF) is more effective as a biomarker in predicting the occurrence of early onset preeclampsia in first trimester or early second trimester of pregnancy.

Methods

A prospective cohort study was conducted on women with singleton pregnancies, screened from the antenatal clinic. Serum PlGF estimation was done at 11–14 weeks of gestation on 1,244 women and at 22–24 weeks of gestation on 1,206 women from the initial study population. A cut-off value of <228 pg/ml for serum PlGF at 11–14 weeks of gestation and <144 pg/ml for serum PlGF at 22–24 weeks of gestation were determined by receiver operating characteristic (ROC) curve analysis for identifying pregnant women at risk of developing early onset preeclampsia (<32 weeks of gestation). Univariate logistic regression analysis was used to analyze the association between serum PlGF < 228 pg/ml at 11–14 weeks of gestation and <144 pg/ml at 22–24 weeks of gestation with the occurrence of early onset preeclampsia and odds ratio (OR) was computed. P value < 0.05 was considered statistically significant in this study.

Results

Maternal serum PlGF <144 pg/ml at 22–24 weeks of gestation had a stronger association (OR 18.83; 95 % CI 12.08–22.24; p = 0.000) than serum PlGF <228 pg/ml at 11–14 weeks of gestation (OR 2.76; 95 % CI 1.29–3.94; p = 0.007) with the occurrence of early onset preeclampsia. The sensitivity and specificity of serum PlGF <144 pg/ml at 22–24 weeks of gestation (84 and 78, respectively) were much higher than those of serum PlGF <228 pg/ml at 11–14 weeks of gestation (58 and 66, respectively) in predicting early onset preeclampsia.

Conclusion

Maternal serum PlGF may be more effective as a biomarker in early second trimester than in first trimester of pregnancy, in predicting the occurrence of early onset preeclampsia.
