High Level of Soluble FMS-Like Tyrosine Kinase-1 (sFlt-1) Serum in Pregnancy as a Risk Factor of Preeclampsia

Abstract

Background: Recently, etiology and pathogenesis of preeclampsia remain unknown. One of the theory indicating that hypoxia and ischemic placenta caused by abnormal cytotrophoblast invasion in preeclampsia. Soluble Fms-like tyrosine kinase-1 (sFlt-1) serum as a laboratory marker of hypoxia condition that contributes to the occurrence of endothelial damage and clinical manifestations in preeclampsia. Objective: This study was aimed at proving that high level of soluble Fms-like tyrosine kinase-1 (sFlt-1) serum in pregnancy as a risk factor for preeclampsia. Methods: This study was a case control. Among 58 pregnant women studied, 29 women with preeclampsia as a case group and 29 women with normal pregnancy as a control group. Soluble Fms-like tyrosine kinase-1 (sFlt-1) serum was analyzed in the Prodia Laboratory. Collected data were tested for normality using Kolmogorov-Smirnov, then analyzed with independent sample test. Chi-Square test used to determine soluble Fms-like tyrosine kinase-1 (sFlt-1) serum level in preeclampsia. Results: This research concluded that the average level of soluble Fms-like tyrosine kinase-1 (sFlt-1) serum in preeclampsia were 11231.00 ± 8390.3 pg/mL and 3981.62 ± 4921.5 pg/mL in normal pregnancy. Analysis of significance with independent t-test concluded that the value of t = 4.01 and p = 0.001. This mean the average levels of soluble Fms-like tyrosine kinase-1 (sFlt-1)serum levels in both groups were difference significantly (p <0.05). Based on the cut-off point of sFlt-1 serum levels was 4505.50 pg/mL with 79.3% sensitivity and 82.8% specificity, the relative risk of preeclampsia was 18 times (OR = 18.40, IK 95% = 4.93 to 68.70, p = 0.001). Conclusion:  Based on this research, high levels of soluble Fms-like tyrosine kinase-1 (sFlt-1) in pregnancy was proved as a risk factor for preeclampsia.
