Abstract


Background: Several studies reveals the correlation of preeclampsia (PE) with low vitamin D (VD) level due to disturbed trophoblast invasion and failure of spiral artery remodeling. The metabolism of VD is regularized by it signaling molecules expressed by the placenta during pregnancy. Therefore, this study was designed to assess and compare the levels of VD and it signaling molecules in placentae from normotensive and preeclamptic pregnancies and their correlation with spiral artery remodeling.

Methods: This study was carried out at Department of Anatomy at Liaquat University of Medical & Health Sciences, Jamshoro after ethical approval on placentae of 122 parturients; 61 from normal and 61 from preeclampsia, data was collected on predesigned proforma and was analyzed on SPSS 23.

Results: The mean and standard deviation of maternal age, gestational age, and parity was 32.73±5.9 years, 37.3±3.6 weeks and 3±1 respectively. The wall thickness of SA and VD when compared in two groups found statically significant. Vitamin D signaling molecules were determined by immunostaining compared in two groups by applying Mann Whitney U test and Pearson’s correlation which reveals significant differences in preeclamptic versus controls.

Conclusions: Despite extensive research indicating a link between low levels of VD and its signaling molecules in the context of inadequate spiral artery remodeling, there is still a need for further investigation to fully understand the mechanisms underlying this association in preeclampsia.
