The predictive value of serum hs-CRP and sFlt-1 levels for fetal growth restriction in patients with ges-tational hypertension / 现代医院

ABSTRACT

Objective To investigate the changes in the levels of serum high-sensitivity C-reactive protein(hs-CRP)and soluble fms-like tyrosine kinase-1(sFlt-1)in hypertensive disorder of pregnancy(HDP)patients with fetal growth restriction(FGR),and to evaluate their predictive value for FGR.Methods A total of 137 HDP patients admitted to the Obstetrics De-partment of Ganzhou Maternal and Child Health Hospital from December 2021 to May 2023 were selected as the study subjects.According to whether their fetuses had growth restriction,they were divided into the restricted group(n=46)and the non-re-stricted group(n=91).The general information and serum levels of hs-CRP and sFlt-1 were collected and analyzed.Multiple lo-gistic regression analysis was used to identify the influencing factors for fetal growth restriction in HDP patients,and receiver oper-ating characteristic(ROC)curve was plotted to evaluate the predictive value of serum hs-CRP and sFlt-1 levels for fetal growth restriction in HDP patients.Results Univariate analysis showed that the serum levels of folic acid(FA),vitamin B12(VitB12),and placental growth factor(PIGF)in the restricted group were lower than those in the non-restricted group,while the serum lev-els of hs-CRP and sFlt-1 were higher than those in the non-restricted group,with statistically significant differences(P＜0.05).Multivariate analysis showed that serum hs-CRP,sFlt-1,and PIGF levels were independent risk factors for fetal growth restriction in HDP patients.The H-L test of the model showedx2=7.014,P=0.535,indicating a good fit.The area under the ROC curve(AUC)was 0.932,with a 95％CI of 0.889-0.975(P＜0.05),a sensitivity of 93.50％,and a specificity of 89.00％.Conclusion Serum hs-CRP and sFlt-1 levels are upregulated in HDP patients with fetal growth restriction,indicating their good predictive value for the occurrence of fetal growth restriction.
