Abstract Objectives To determine the effect of prenatal vitamin D supplementation on expression of angiogenic factors in the placenta. Methods This is a secondary analysis of the Maternal Vitamin D for Infant Growth trial, a randomized controlled trial of maternal vitamin D supplementation in Dhaka, Bangladesh. We examined the expression of angiogenic factors in placental tissues. Women (n = 1300) were enrolled at 17–24 weeks gestation and randomized to receive: placebo, 4200 IU/week, 16,800 IU/week or 28,000 IU/week until delivery. We examined a subset of randomly selected placentas (n = 80) collected at birth, which included 20 tissues (10 male & 10 female offspring) from each treatment group in maternal/fetal pairs. A full thickness placental core was collected; fixed in formalin and embedded in paraffin. Tissue sections were stained for vascular endothelial growth factor (VEGF) and placental growth factor (PlGF) using immunofluorescence. ImageJ was used to quantify intensity and % area of expression. T-tests were used to estimate the effects of each vitamin D dose on expression of angiogenic factors, compared to placebo. Interactions by fetal sex were also examined. Results The mean (SD) for % area of expression was 17.0 (4.0) for VEGF and 14.8 (1.9) for PlGF. The mean (SD) for intensity was 6520 (1549) for VEGF and 5716 (734) for PlGF. There were no significant differences in VEGF and PlGF between any vitamin D treatment groups versus placebo for % area or intensity of expression (Table 1). The effect of vitamin D treatment was not modified by fetal sex. Conclusions Vitamin D supplementation starting from mid-pregnancy until delivery did not effect expression of two key angiogenic factors in the placenta at term. The impact of periconception vitamin D supplementation on expression of angiogenic factors in the placenta remains unknown. Funding Sources Bill and Melinda Gates Foundation.

Background: Vitamin D has a steroid- and an anabolic-resembling chemical structure. Vitamin D is essential for many processes in the human body after hydroxylation. Aims of the Study: To investigate the impact of 25-hydroxy-vitamin D plasma concentrations on the blood parameters number of erythrocytes, hematocrit, mean corpuscular hemoglobin and mean corpuscular volume. Methods: Serial assessments were done in 290 patients with multiple sclerosis and repeated after a mean interval of 245 days. A recommendation for vitamin D supplementation was given in case of a concentration lower than 20 ng/mL combined with a prescription of a formulation containing vitamin D but not vitamin K. Results: There was a fall of vitamin D in 119 subjects and a rise in 164, while no change appeared in 7 participants. When vitamin D values went down between both assessments moments, the computed increase of mean corpuscular haemoglobin was significantly lower compared with the rise of mean corpuscular haemoglobin associated with a vitamin D elevation. When vitamin D declined, the computed fall of mean corpuscular volume fall was significantly lower compared with the decrease of mean corpuscular volume, when vitamin D rose. Positive correlations were found between differences of vitamin D and mean corpuscular haemoglobin, respectively mean corpuscular volume. Inverse relations appeared between disparities of vitamin D and erythrocytes, respectively haematocrit. Conclusions: The elevation of vitamin D plasma levels provides enhanced preconditions for a better tissue oxygenation on a cellular level.

The Impact

Vitamin D is a vital nutrient factor in the healthiness of the mother and infant. Vitamin D is mainly amalgamated in the skin following exposure to ultraviolet B radiation. Insufficiency of vitamin D in Pregnancy had been related to various sicknesses, such as respiratory infection, type 1 diabetes mellitus, high risk of childhood wheezing. The aim of this study was to investigate the impact of Vitamin D supplementation on the incidence of pregestational diabetes in pregnant women referred to antenatal clinics in SRM Medical College hospital, Tamilnadu, India. 200 pregnant women were recruited, and oral glucose challenge test (OGCT), serum calcium and 25(OH) D were determined. Participants were in the age group of 18 to 35 years, with a mean age of 26.29. Among the participants, 59% were multiparous. The present study showed that a high prevalence of vitamin D deficiency (61.5%) and insufficiency (34%) in pregnant women before supplementation with a mean of 16.84. Vitamin D supplementation during the early weeks of pregnancy might help in the improvement of maternal and child health.

Abstract Objectives Maternal vitamin D status has gained substantial attention as a modifiable contributor to offspring musculoskeletal health, yet there is a paucity of trial-derived data to corroborate effects of prenatal or postpartum vitamin D supplementation on offspring bone mass accrual. Among maternal-infant pairs in Bangladesh, we aimed to examine the hypothesized causal association of early life vitamin D exposure with musculoskeletal health in childhood. Methods In a double-blind dose-ranging trial of maternal vitamin D3 supplementation (Maternal Vitamin D for Infant Growth Trial), healthy pregnant women (n = 1300) were recruited at 17–24 weeks’ gestation and randomly assigned to receive a prenatal; postpartum regimen of 0;0,4200;0,16,800;0,28,000;0 or 28,000;28,000 IU vitamin D3/week until 26 weeks postpartum. In a follow-up study of offspring at 4 years of age (n = 642), bone mineral content (BMC) and bone mineral density (BMD) were measured by dual-energy X-ray absorptiometry. Between-group differences were assessed by independent t-tests (28,000 IU/week prenatally vs placebo) and linear regression (each vitamin D treatment group vs placebo) with bootstrapping (1000 replications). Results Whole-body (WB), total-body-less-head (TBLH) and head-only BMC were similar in the combined high-dose prenatal and placebo groups (mean difference [95% CI] = 6.81g [−8.70, 22.32], 0.61g [−10.90, 12.13] and 1.71g [−3.54, 6.96], respectively). None of the mean values for WB or TBLH BMC or BMD in each vitamin D group were different from placebo (P > 0.05 for all comparisons). Although head BMD was slightly greater in offspring of women assigned to the 28,000;28,000 IU regimen compared to placebo (mean difference [95% CI] = 0.024g/cm2 [0.0009, 0.047], P = 0.042), the effect was attenuated and no longer significant upon adjustment for child height, weight, and sex (P = 0.11). Conclusions In a population with high prevalence of vitamin D deficiency, our findings do not support the use of maternal prenatal vitamin D supplementation, with or without postpartum supplementation, for improvement of child BMC or BMD at 4 years of age.
