Role of Vitamin-D Receptor (VDR) single nucleotide polymorphisms in gestational hypertension development: A case-control study.


ABSTRACT: BACKGROUND:Recent literature data have highlighted the important role of hypovitaminosis D in pregnancy complications and prenatal/perinatal health. Vitamin D action takes place through vitamin D receptor (VDR) activation. Two single nucleotide polymorphisms of VDR gene, FokI and BsmI, have been reported to affect VDR molecular signaling and be associated with several disorders, including hypertension. METHODS:We carried out a case-control study aimed to assess vitamin D serum levels together with the distribution of VDR FokI and BsmI in a population of 116 pregnant women with gestational hypertension (GH) and 69 normotensive pregnant women (CTR). RESULTS:Hypovitaminosis D was largely prevalent both in GH (81%) and CTR (69%) pregnant women. Vitamin D insufficiency (10-30 ng/ml) had a similar frequency in both cohorts (GH 60% vs CTR 58%), while vitamin D deficiency (<10 ng/ml) was more frequent in GH cohort than in CTR one (21% vs 11%). Regression analysis showed that GH was significantly (p = 0.031) linked to vitamin D status. Vitamin D deficiency was associated with a threefold-increased risk of developing GH, while a normal vitamin D status was protective against this pregnancy disorder. The VDR FF/bB haplotype was the most frequent in GH cohort, and resulted to increase by two folds the risk for GH. Notably, hypovitaminosis D was found in 92% of FF/bB GH pregnant women, 27% of which had deficient vitamin D levels compared with 11% of their normotensive counterparts. CONCLUSIONS:Despite being preliminary, these findings suggest that genotyping of pregnant women for VDR polymorphisms may be useful for a tailored vitamin D supplementation strategy.
