ABSTRACT
Objective To explore the clinical diagnostic value of joint detection of serum platelet-derived growth factor BB (PDGF-BB), soluble vascular endothelial growth factor receptor -1 (sFlt-1) and urotensinⅡ( U-Ⅱ) in preeclampsia disease.Methods The cases of obstetric patients suffering from preeclampsia in the Third People′s Hospital of Liaocheng , Shandong Province between October 2012 and April 2014 were enrolled , including 96 cases of mild preeclampsia and 81 cases of severe preeclampsia.Totally 68 cases of normal pregnant women with similar age and gestational age were selected as control group.A case-control study was applied for the following investigations.The concentrations of serum PDGF-BB, sFlt-1 and U-Ⅱwere measured using ELISA.The diagnostic value of PDGF-BB, sFlt-1 and U-Ⅱalone or in combination for preeclampsia was analyzed and evaluated with receiver operating characteristic curve ( ROC) and Logistic regression analysis.Results Serum concentrations of PDGF-BB, sFlt-1 and U-Ⅱin mild preeclampsia group were (80.45 ±21.87)ng/L,(23.03 ±6.67)μg/L and(4.54 ± 1.02)ng/L, and those in severe preeclampsia group were (124.91 ±47.54)ng/L,(35.65 ±12.45)μg/L and(6.29 ±2.31) ng/L, while those in control group were (60.89 ±19.38) ng/L,(17.19 ±7.867)μg/L and ( 3.81 ±1.01 ) ng/L, respectively.The three parameters in mild preeclampsia group and severe preeclampsia group were significantly higher than those in control group ( P<0.01; F value was 79.43, 79.28 and 50.72 respectively ).In the same situation , these three indicators in severe preeclampsia group were significantly higher than those in mild group (P<0.01).Moreover, the AUC of serum PDGF-BB, sFlt-1 and U-Ⅱalone or in combination were 0.821, 0.786, 0.772 and 0.933, respectively.The differences between joint detection and three individual detections were statistically significant ( P<0.05 ) , as combined detection having a sensitivity of 95.7% and a specificity of 86.6%.Conclusion The combined detection of Serum PDGF-BB, sFlt-1 and U-Ⅱ had an important value in early assessment and treatment of preeclampsia.
