Perbandingan Kadar Soluble Fms-Like Tyrosine Kinase 1 (SFLT1) Serum Kehamilan Normal dengan Preeklamsi Berat Serta Hubungannya dengan Tekanan Darah dan Derajat Proteinuria

Abstract

Prediction and early detection of preeclampsia is very important to reduce maternal and perinatal morbidity and mortality. This research was to find out the difference of serum sFlt1 level between normal pregnancy and severe preeclampsia (SPE) and to determine the correlation of serum sFlt1 level with blood pressure as well as the degree of proteinuria. This was an analytic observational cross sectional study. Measurement of serum sFlt1 level using ELISA. >Statistical analysis was performed by using chi square, t test, Mann-Whitney test, Spearman Rank correlation coefficient and diagnostic test for cut-off point determination.The characteristics of the subjects in both groups were not statistically different (p>0.05). There was a significant difference in sFlt1 level between SPE group and control group (3,827±471 pg/mL and 2,708±441 pg/mL subsequently; p<0.05). There were significant association between sFlt1 level and systolic blood pressure (p=0.042; p<0.05 ); between sFlt1 level and diastolic blood pressure (p=0.041; p<0.05); and between sFlt1 level and degree of proteinuria (p=0.012; p<0.05). The cut-off point of sFlt1 level to differentiate SPE from normal pregnancy was 2,815 pg/mL with sensitivity of 97.1%, specificity 42% and accuracy of 69.6%.There is statistically significant difference of sFlt1 level in SPE compared to normal pregnancy. Significant association is noted between sFlt1 level and systolic and diastolic blood pressure, as well as degree of proteinuria. The cut-off point of sFlt1 level is 2,815 pg/mL.
