Abstract:

Objective To investigate the relationship between the expression of serum fibroblast growth factor 2(FGF2) and fibroblast growth factor receptor 1(FGFR1) and pregnancy outcome in patients with preeclampsia(PE). Methods Totally,82 PE patients diagnosed in Maternal and Child Health Hospital of Henan Province from January 2021 to December 2022 were enrolled as study subjects,which included 44 cases of good outcome and 38 cases of adverse outcome,and another 82 pregnant females with successful delivery were enrolled as healthy control group. Serum FGF2 and FGFR1 levels were determined. The correlation of FGF2 and FGFR1 was analyzed by Pearson analysis. The influencing factors of adverse pregnancy outcome in PE patients were analyzed by Logistic regression analysis. The predictive values of serum FGF2 and FGFR1 on adverse pregnancy outcome in PE patients was evaluated by receiver operating characteristic(ROC) curve. Results Serum FGF2 and FGFR1 levels were higher in healthy control group than in PE group(P<0.05),and serum FGF2 and FGFR1 levels in adverse outcome group were lower than those in good outcome group(P<0.05). The percentages of early PE and severe PE in adverse outcome group were higher than those in good outcome group(P<0.05). There was no statistical significance for the other clinical data between the 2 groups(P>0.05). FGF2 was positively correlated with FGFR1 in PE group(r=0.524,P<0.05). Both early PE [odds ratio(OR)=3.682,95% confidence interval(CI)1.054-12.858] and severe PE(OR=4.029,95%CI 1.086-14.951) were risk factors for adverse pregnancy outcome in PE patients(P<0.05),and increased FGF2(OR=0.491,95%CI 0.293-0.822) and increased FGFR1(OR=0.586,95%CI 0.382-0.898) were protective factors(P<0.05). The areas under curves(AUC) for the single and combined determinations of serum FGF2 and FGFR1 for adverse pregnancy outcome in patients with PE were 0.81,0.82 and 0.92,respectively. Conclusions The levels of serum FGF2 and FGFR1 of PE patients with adverse outcome are lower than those of patients with good outcome,and the combined determination has good predictive value of adverse pregnancy outcome in PE patients.
