Placenta, Preeclampsia, Spiral artery, VDR, Vitamin D deficiency


Objective: This study is intended to conclude the vitamin D status and VDR gene, with its relation in spiral artery remodeling in normal and pre eclamptic women.

Study Design: Cross-sectional study.

Place and Duration: This study was conducted in Department of Anatomy with collaboration of Department of Gynecology and Obstetrics of Liaquat University Hospital Hyderabad and Jamshoro from August 2021 to July 2022.

Methodology:  After ethical approval vide letter (LUMHS/REC/632) total 122 women; of 20-40 years of age with full term, singleton pregnancy, 61from normal-term pregnancies as controls and 61 from preeclampsia were registered at labor room of OBG. After demographic data with septic measures maternal blood sample of 5cc was collected before delivery for assessment of VD and their placentae were collected from labor room immediately after delivery along with 5cm of umbilical cord attached to it. After morphological examination of placenta, sectioning of placenta was performed for microscopic examination. Standard protocol for H &E and immunohistochemistry for VDR were followed performed. Sections were viewed under light microscope and Image J software was used for analysis.

Results: Mean±SD of maternal age, parity and gestational age (in weeks), wall thickness of spiral artery and % of VDR positive cells of study participants were 32.7 years±5.9, 3.9±1.4, 37.3±3.6, 48.11±23.5295 and , 46.49±18.779 respectively. (table1). Mean and SD of vitamin D levels and placental weight (table2) and wall thickness of spiral artery and % of VDR positive stained cells when compared on Image J software between normal and preeclamptic patients is highly significant(table 3).

Conclusions: Abnormal remodeling of spiral artery is significantly associated with low levels of Vitamin D and its receptors, leading to placental diseases such as preeclampsia.
