Perbedaan Rerata Kadar Soluble Fms-Like Tyrosine Kinase-1 (Sflt-1) Serum pada Penderita Early Onset, Late Onset Preeklampsia Berat / Eklampsia dan Kehamilan Normal

Abstract

AbstrakPreeklampsia merupakan sumber utama morbiditas dan mortalitas ibu di seluruh dunia. Kegagalan pengaturan dan ketidakseimbangan agen vasoaktif proangiogenik dan antiangiogenik plasenta, soluble fms-like tyrosine kinase-1 (sFlt-1), vascular endothelial growth factor (VEGF) dan placental growth factor (PlGF) memainkan peran penting dalam patogenesis preeklampsia. Tujuan penelitian ini adalah menentukan perbedaan rerata kadar sFlt-1 serum pada penderita early onset, late onset preeklampsia berat/ eklampsia dan kehamilan normal. Penelitian dilakukan di RSUP Dr. M. Djamil, RS TK. III dr. Reksodiwiryo dan Laboratorium Biologi Molekuler Fakultas Kedokteran Universitas Andalas Padang dari Februari sampai Desember 2014 dengan desain cross sectional. Subjek berjumlah 84 orang, terdiri dari tiga kelompok, yaitu kelompok early onset preeklampsia berat/ eklampsia, late onset preeklampsia berat/ eklampsia, dan kehamilan normal sebagai kelompok kontrol yang diambil dengan teknik consecutive sampling. Darah dikumpulkan dari subjek penelitian dengan cara intravena kemudian diukur dengan metode ELISA. Rerata kadar sFlt-1 pada kelompok early onset, late onset preeklampsia berat/ eklampsia dan kehamilan normal secara berturut-turut adalah 4,69±0,96 ng/ml, 2,39±0,57 ng/ml, dan 1,23±0,42 ng/ml. Perbedaan ini sangat signifikan dengan uji statistik ANOVA (p<0,05) dan uji Post Hoc Test Multiple Comparisons. Kesimpulan penelitian adalah terdapat perbedaan yang sangat signifikan antara kadar sFlt-1 serum pada kelompok early onset preeklampsia berat/ eklampsia, late onset preeklampsia berat/ eklampsia dan kehamilan normal.Kata kunci: sFlt-1, antiangiogenik, preeklampsia berat/ eklampsia, kehamilan normal AbstractPreeclampsia is a major cause maternal morbidity and mortality in the world. Failure regulation and imbalance of vasoactive agents and antiangiogenic proangiogenik placenta, soluble fms-like tyrosine kinase-1 (sFlt-1), vascular endothelial growth factor (VEGF) and placental growth factor (PlGF) have an important role in the pathogenesis of preeclampsia. The objective of this study was to determine the differences between the mean serum levels of sFlt-1 in patients with early onset, late onset severe preeclampsia/eclampsia and normal pregnancy. This study was conducted in Dr. M. Djamil hospital, dr. Reksodiwiryo TK. III hospital and Biology Moleculer Laboratory Medicine Faculty of Andalas University Padang from February until December 2014 with a cross sectional design. The total subjects were 84 persons, consist of three groups, there was early onset severe preeclampsia/ eclampsia, late onset severe preeclampsia/ eclampsia and normal pregnancy as control group. The subjects were selected by consecutive sampling technique. The blood was collected by intravenous, then sFlt-1 serum measured by ELISA. The mean levels of sFlt-1 in the early onset group, late onset severe preeclampsia/ eclampsia group and normal pregnancy group were 4.69±0.96 ng/ml, 2.39±0.57 ng/ml and 1.23±0.42 ng/ml. This difference very significant by ANOVA statisctical test (p<0,05) and Multiple Comparisons Post Hoc Test. The conclusion of this study is very significant differences between serum levels of sFlt-1 in early onset severe preeclampsia/ eclampsia group, late onset severe preeclampsia/ eclampsia on normal pregnancy.Keywords: sFlt-1, antiangiogenic, severe preeclampsia/ eclampsia, normal pregnancy
