ABSTRAKLatar Belakang. Perempuan dengan preeklampsia memiliki resiko tinggi
terhadap penyakit kardiovaskuler 5-15 tahun pasca kehamilan. Disfungsi endotel
diperkirakan menjadi patogenesis manifestasi klinik preeklampsia dan
penghubung antara preeklampsia dan kejadian kardivaskular setelah kehamilan.
Nilai flow mediated vasodilation (FMD) dari arteri brakhialis pada sebagian
subset preeklampsia tetap rendah 3-10 tahun pasca-melahirkan. Proteinuria pada
preeklampsia secara etiologi juga berhubungan dengan disfungsi endotel
glomerulus. Namun, tidak seperti pada populasi hipertensi dan diabetes mellitus,
sampai saat ini belum diketahui bagaimana korelasi antara nilai proteinuria
dengan nilai FMD pada populasi preeklampsia.
Tujuan : Untuk mengetahui hubungan/korelasi antara proteinuria terhadap nilai
FMD pada preeklampsia sebelum dan sesudah melahirkan
Metode. Studi prospektif dilakukan di tiga rumah sakit. Subyek preeklampsia
yang akan diterminasi dan sesuai kriteria inklusi dan eksklusi diperiksa nilai FMD
dan rasio protein-kreatinin urinnya (RPKU) sebelum melahirkan, 48-72 jam
setelah melahirkan dan pasca-nifas. Data kemudian diolah dengan analisis bivariat
dan multivariat untuk mengetahui korelasi antara rasio protein-kreatinin urin
dengan nilai FMD dan perubahannya sebelum dan setelah melahirkan.
Hasil Penelitian. Sebanyak 30 perempuan preeklampsia diikutsertakan dalam
penelitian ini. Rerata nilai FMD sebelum melahirkan, 48-72 jam pasca-melahirkan
dan follow up pasca-nifas adalah 5.46 ± 0.27 ,, 6.10 ± 0.35 dan 8.14 ± 2.48 ( p
<0.001). Ditemukan 40 % subyek masih dengan FMD < 7 saat pemeriksaan
pasca-nifas (40-60 hari). Uji korelasi bivariat menunjukkan korelasi dengan arah
negatif yang kuat antara proteinuria (RPKU) pasca-nifas dengan nilai FMD pascanifas
(r= -0.73, p <0.001) , dan nilai RPKU sebelum melahirkan berhubungan
dengan rendahnya FMD pasca-nifas dan perubahan (delta) FMD sebelum-sesudah
melahirkan. Tidak diperoleh korelasi bermakna antara proteinuria dan nilai FMD
sebelum melahirkan. Analisis multivariat dengan regresi linier membuktikan
korelasi yang independen antara proteinuria dan nilai FMD pasca-nifas dan delta
FMD.
Kesimpulan. Studi ini menegaskan korelasi yang kuat yang arahnya negatif
antara nilai proteinuria pasca-melahirkan dengan nilai flow mediated dilation
pasca melahirkan pada subyek preeklampsi dan semakin tinggi nilai proteinuria
sebelum melahirkan berhubungan dengan rendahnya perubahan FMD sebelum
dan sesudah melahirkan.
ABSTRACTBackground. Endothelial dysfunction was associated with both of the
predisposition of preeclampsia and the later development of vascular disease.
Flow mediated dilation (FMD) was reduced in preeclamptic women and persist
after delivery in several cases. Proteinuria in preeclampsia was also a
manifestation of endothelial dysfunction in kidney, but there was no data untill
now showing the correlation of FMD and the level of proteinuria in preeclamptic
woman
Objectives. To asses the correlation between urine protein-creatinine ratio and
flow mediated dilation (FMD) before and after delivery in preeclamptic women.
Methods. Women with a diagnosis of preeclampsia and planned for termination
were enrolled for the study. History of hypertension before 20 weeks of gestation,
diabetes mellitus, chronic kidney disease became exclusion criterias. The FMD
was studied through the use of high resolution vascular ultrasound examination of
brachial artery for 3 times; before delivery, 48-72 hours after delivery and 40-60
days after delivery. Urine protein-creatinine ratio (UPCR) was measured twice;
prior to delivery and 40-60 days after delivery. Correlation between them was
then evaluated.
Results. Thirty patients were enrolled in this study. The mean ages was 29.5±6,4
years old. FMD was improved after delivery, 5.46 ± 0.27 % (before delivery) &
8.14 ± 2.48 % ( p <0.001) 40-60 days after delivery. Bivariates analysis showed
that after delivery, there was an inverse correlation between UPCR with FMD (r=0,735
p<
0,0001).
UPCR
prior
to
delivery
also
has
inverse
correlation
with
FMD
after
delivery (r= -0.55.p=0.002) and with the change of FMD before and after
delivery (r= -0.45 with p =0.01). Multivariate analysis showed that correlation
between UPCR after delivery with FMD after delivery was independent.
Conclusion. This study demonstrated there was a moderate-strong correlation
between urinary protein prior and after delivery with flow mediated vasodilatation
of brachial artery after delivery.
