This longitudinal study was carried out in Pune, India. A total of 1154 women with singleton pregnancies were recruited in early pregnancy from two hospitals. Blood samples were collected and stored at four time points across gestation: V1 = 11-14 weeks, V2 = 18-22 weeks, V3 = 26-28 weeks and V4 = at delivery. 108 women who developed preeclampsia (PE) and 216 who did not develop PE (Non-PE) were randomly selected from the remainder. Serum 25-hydroxy vitamin D concentrations (25(OH)D) were estimated in their samples using commercially available ELISA kits. Independent t-tests were used to compare 25(OH)D between PE and non-PE groups. Logistic and linear regressions were used to examine associations of 25(OH)D with the risk of preeclampsia and birth outcomes, respectively, after adjusting for confounders. The mean (SD) 25(OH)D at V1 was 21.95 (19.64) in the Non-PE group and 17.76 (13.21) in the PE group.
A decrease in the concentrations of vitamin D (ng ml-1) in mid-pregnancy (V2) and at delivery was associated with an increased risk of preeclampsia (0.31 [95% CI 0.11, 0.86], p = 0.024 and 0.24 [95% CI 0.08, 0.77], p = 0.016), respectively. Our finding of lower vitamin D concentrations in mid-pregnancy, before women developed clinical preeclampsia, suggests that vitamin D may have a role in its pathophysiology.

Objective
Preeclampsia is a multifactorial disease characterized by high blood pressure and protein in the urine. In this study, we investigated the association of vitamin D binding protein (GC) and vitamin D receptor (VDR) gene polymorphism with the risk of developing preeclampsia.Methods
25-hydroxyvitamin D was measured using High-performance Liquid Chromatography. Vitamin D binding protein and vitamin D receptor gene polymorphisms were determined by polymerase chain reaction-restriction fragment length polymorphism.Results
The control subjects have significant higher level of 25-hydroxyvitamin D (33.5 ± 1.194 ng/mL) relative to patients (23.97 ± 1.604 ng/mL) (p < 0.05). Vitamin D receptor rs1544410 and rs2228570 dominant model (GA + AA; TC + CC) showed significant higher risk of developing Preeclampsia (OR = 4.11, 95% CI = 0.62–27.09, p < 0.01; OR = 3.58, 95%CI = 0.78–16.38, p < 0.001 respectively). Similarly, vitamin D binding protein rs7041 and rs4588, dominant model (TG + GG; CA + AA) showed higher risk of preeclampsia development compared to control people (OR = 1.69, 95%CI = 0.35–8.19, p < 0.05; OR = 1.06, 95%CI = 0.25–4.44, p < 0.05 respectively). AA genotype of rs4588 of GC gene was significantly associated with 25-hydroxyvitamin D level in serum relative to CC and CA (p < 0.05).Conclusion
From our study, we can conclude that a low level of 25-hydroxyvitamin D, GC (rs1544410 and rs2228570), and VDR (rs4588 and rs7041) gene polymorphism is linked with an increased risk of developing preeclampsia.

Preeclampsia 1.5 more-likely if poor Vitamin D Receptor - meta-analysis April 2023
Association between Vitamin D receptor (VDR) gene polymorphisms and hypertensive disorders of pregnancy: a systematic review and meta-analysis
PeerJ. 2023 Apr 25;11:e15181. doi: 10.7717/peerj.15181
Yicong Guo # 1, Yu Zhang # 2, Xiangling Tang 2, Xionghao Liu 2, Huilan Xu 1Background: Hypertensive disorders of pregnancy (HDP) are currently one of the major causes of pregnancy-related maternal and fetal morbidity and mortality worldwide. Recent studies provide evidence that maternal Vitamin D receptor (VDR) gene polymorphisms probably play a key role by affecting the biological function of vitamin D in some adverse pregnancy outcomes, while the relationship between the VDR gene polymorphisms and the risk of HDP remains controversial in current studies. This systematic review and meta-analysis aimed to comprehensively evaluate the association of the VDR gene polymorphisms with HDP susceptibility.
Methods: This meta-analysis follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement and a protocol has been registered in the PROSPERO (ID: CRD42022344383) before commencing this review. PubMed, Web of Science, Embase, and the Cochrane Library databases were searched until January 21, 2023. Case-control and cohort studies that reported the association of the VDR gene polymorphisms with HDP were included. The quality of the included studies was assessed using the Newcastle-Ottawa Scale (NOS) for non-randomized studies. The odds ratios (ORs) with corresponding 95% confidence intervals (CIs) of the five models (allele model, dominant model, recessive model, homozygous model, heterozygous model) were pooled respectively, and subgroup analysis was performed based on ethnicity.
Results: A total of ten studies were included. The VDR gene ApaI polymorphism was associated with HDP susceptibility in the dominant model (OR: 1.38; 95% CI [1.07-1.79]; P = 0.014) and the heterozygote model (OR: 1.48; 95% CI [1.12-1.95]; P = 0.006). In subgroup analysis, the heterozygote model (OR: 2.06; 95% CI [1.21-3.52]; P = 0.008) of the ApaI polymorphism was associated with HDP in Asians, but not in Caucasians.
Conclusion: The VDR gene ApaI polymorphism may be associated with HDP susceptibility. Insufficient evidence to support the existence of ethnic differences in this association.

Could Vitamin D Be Effective in Prevention of Preeclampsia? - Oct 2021
Nutrients 2021, 13(11), 3854; https://doi.org/10.3390/nu13113854

Prevention of preeclampsia (PE) remains one of the most significant problems in perinatal medicine. Due to the possible unpredictable course of hypertension in pregnancy, primarily PE and the high complication rate for the mother and fetus/newborn, it is urgent to offer pregnant women in high-risk groups effective methods of preventing the PE development or delaying its appearance. In addition, due to the association of PE with an increased risk of developing cardiovascular diseases (CVD) in later life, effective preeclampsia prevention could also be important in reducing their incidence. Ideal PE prophylaxis should target the pathogenetic changes leading to the development of PE and be safe for the mother and fetus, inexpensive and freely available. Currently, the only recognized method of PE prevention recommended by many institutions around the world is the use of a small dose of acetylsalicylic acid in pregnant women with risk factors. Unfortunately, some cases of PE are diagnosed in women without recognized risk factors and in those in whom prophylaxis with acetylsalicylic acid is not adequate. Hence, new drugs which would target pathogenetic elements in the development of preeclampsia are studied. Vitamin D (Vit D) seems to be a promising agent due to its beneficial effect on placental implantation, the immune system, and angiogenic factors. Studies published so far emphasize the relationship of its deficiency with the development of PE, but the data on the benefits of its supplementation to reduce the risk of PE are inconclusive. In the light of current research, the key issue is determining the protective concentration of Vit D in a pregnant woman. The study aims to present the possibility of using Vit D to prevent PE, emphasizing its impact on the pathogenetic elements of preeclampsia development.

Preeclampsia meta-analyses
Conclusions
Currently, the commonly recommended preeclampsia prophylaxis is the use of low doses of acetylsalicylic acid in high-risk pregnant women and, by some institutions, calcium supplementation in groups with its deficiencies in the diet. Numerous studies are being conducted on the use of other substances and drugs for this purpose, which, due to their properties and mechanisms of action, could prevent the development of preeclampsia. One of these thoroughly studied substances is vitamin D. Based on the results of research explaining its mechanism of action and understanding the reasons and pathophysiology of the development of preeclampsia, it might be postulated that an anti-inflammatory effect of Vit D and its beneficial influence on the endothelium constitutes its potential use in PE prevention. Unfortunately, the results of the randomized controlled trials and meta-analyses are ambiguous. Despite the multitude of studies published on this subject, there are no clear conclusions about its effectiveness in PE prevention which could form the basis for developing universal recommendations.
In the light of the available data, the following issues regarding the role of vitamin D in preventing preedampsia remain unresolved:- 1. Should the target group for vitamin D supplementation be all pregnant women or only those at high risk?
- 2. Should it be recommended to test the vitamin D concentration in the periconceptional period and the early first trimester in all pregnant women or a high-risk group?
- 3. Since when (during the planning period of pregnancy or in the first trimester),
- how long and what doses of vitamin D should be proposed considering the safety of offspring?
- 4. What vitamin D level in the periconceptional period and the first trimester should be considered sufficient?
These questions may determine the direction of research on vitamin D in the prevention of preeclampsia.
It seems that the fundamental issue, despite the extensive literature, remains the assessment of Vit D concentration in the periconceptional period and/or the early first trimester and defining levels that would allow reducing the risk of PE development. Women with risk factors for Vit D deficiency such as obesity, kidney, liver, thyroid gland diseases, chronic bowel diseases, autoimmune diseases, asthma, diabetes t.2, hypertension, and chronic glucocorticoids, antiepileptic and antiretroviral drug treatment would benefit the most from screening. It appears that patients with risk factors for PE development and Vit D deficiency may require higher doses of vitamin D than commonly recommended for pregnant women.
