[PMID: 37741089 DOI: 10.1016/j.nut.2023.112194] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2023] [Revised: 08/08/2023] [Accepted: 08/10/2023] [Indexed: 09/25/2023]
Abstract
OBJECTIVE The aim of this study was to evaluate the influence of serum 25-hydroxyvitamin D [25(OH)D] levels at birth in postnatal growth at discharge and 12 mo of corrected age in preterm infants. METHODS This prospective cohort included 63 preterm newborns born before 34 gestational weeks evaluated from birth until 12 mo of corrected age. The serum 25(OH)D levels in umbilical cord blood and from their mothers were evaluated at delivery. RESULTS The mean 25(OH)D levels in preterm newborns were higher than maternal levels (24.8 ± 13.3 ng/mL versus 21 ± 10.2 ng/mL, P < 0.001) and showed a moderate correlation between (r = 0.548; P < 0.001). Considering the body mass index Z-score at 12 mo, 3 (10%), 25 (83%), and 2 (7%) of the preterm infants were thin, had normal body mass index, and were overweight, respectively. The 25(OH)D levels in the umbilical cord did not influence the anthropometric indicators at hospital discharge and 12 mo of corrected age. We observed improvement in all anthropometric indicators assessed over the months, and there was no difference between preterm infants with 25(OH)D levels >20 ng/mL and <20 ng/mL in the umbilical cord. CONCLUSIONS The results of this study suggested that the 25(OH)D serum levels in the umbilical cord did not influence postnatal growth from birth to the first year of life in preterm infants. There was a direct association between maternal and umbilical cord serum 25(OH)D levels.

Abstract
Context Vitamin D inadequacy is globally prevalent among pregnant women; however, its impact on pregnancy remains inconclusive. Objective This study aims to explore the associations of maternal and umbilical cord serum 25-hydroxyvitamin D (25(OH)D) levels with pregnancy and neonatal outcomes. Method We used archived serum samples from the Hyperglycemia and Adverse Pregnancy Outcome (HAPO) Study participants in the Hong Kong center and assayed maternal 25(OH)D levels at midgestation and umbilical cord 25(OH)D at birth using liquid chromatography-tandem mass spectroscopy. Data regarding pregnancy and perinatal outcomes were extracted from the HAPO study dataset and the hospital computerized medical system. Results Only 247 (16.4%) mothers and 66 (5.0%) neonates met the criteria for vitamin D sufficiency (ie, 25(OH)D ≥ 75 nmol/L). The ratio of umbilical cord to maternal vitamin D levels was positively associated with maternal age and ambient solar radiation at the month of delivery, while negatively associated with maternal serum total 25(OH)D at midgestation (all P < .001). Umbilical cord serum 25(OH)D was independently associated with a lower primary cesarean section rate (OR 0.990, 95% CI 0.982-0.999; P = .032). There were no associations of maternal and umbilical cord 25(OH)D levels with other adverse pregnancy and neonatal outcomes. Conclusion Placental vitamin D transfer was found to be higher with a lower maternal vitamin D level, older maternal age, and higher ambient solar radiation at the time of the delivery. The protective effect of sufficient vitamin D in a cesarean section will require further studies.

Abstract
OBJECTIVE This systematic review aimed to map the evidence evaluated the relationship between vitamin D and redox and inflammatory status during gestation. METHODS Three databases (PubMed/MEDLINE, Scopus, and Web of Science (WoS)) and reference list of included documents were searched for related observational studies published until 2nd October 2023. To determine the quality of the selected observational studies, the Newcastle-Ottawa Scale (NOS) was used. RESULTS After a primary search of three databases, 19492records were appeared. When duplicates and irrelevant documents were removed, 14 articles were found to have eligible criteria. The design of the identified studies was cross-sectional, case-control and cohort. Evidence showed an adverse association between 25(OH)D and the biomarkers of inflammation, such as high-sensitivity C-reactive protein (hs-CRP), Interleukin-1beta (IL-1β), Interleukin-6 (IL-6), and tumor necrosis factor- alfa (TNF-α) during pregnancy. On the contrary, some studies represented that 25(OH)D positively correlated with hs-CRP in the cord blood. One study suggested a direct association between serum concentrations of 25(OH)D and Interleukin-8 (IL-8), macrophage inflammatory protein (MIP), and TNF-α levels in mothers with gestational diabetes mellitus (GDM). A case-control study showed that lower serum concentration of 25(OH)D positively correlated with total antioxidant capacity (TAC) levels in participants. CONCLUSIONS Evidence confirmed the supposition of the direct relationship between vitamin D levels and biomarkers with anti-inflammatory and anti-oxidative properties. However, the Existence of inconsistent evidence confirms the need for further studies in mothers with GDM and hypertensive disorders. PROSPERO REGISTRATION CODE CRD42020202600.

Does maternal vitamin D status influence placental weight or vascular and inflammatory pathology? Secondary analysis from the Kellogg Pregnancy Study. J Steroid Biochem Mol Biol 2023; 233:106358. [PMID: 37414103 PMCID: PMC11229515 DOI: 10.1016/j.jsbmb.2023.106358] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/14/2023] [Revised: 05/10/2023] [Accepted: 06/26/2023] [Indexed: 07/08/2023]
Abstract
INTRODUCTION Positive effects of vitamin D (vitD) supplementation on comorbidities of pregnancy (COP) have been explored; however, few studies have elucidated the pathophysiology behind the development of these COP and the potential relationship with derangements in placental development and morphology. Additionally, it is known that placentas weighing 10th-90th % for gestational age are associated with better outcomes. Therefore, the objective of this study was to assess the impact of resulting circulating serum 25(OH)D concentrations associated with intake of high or low doses of supplementary vitD on placental development and morphology in women who participated in a randomized double blind, placebo-controlled trial of vitD supplementation. We hypothesized that if maternal serum 25(OH)D concentration (vitD status marker) is insufficient/deficient, then placental weight and % for gestational age (GA) will be smaller and will correlate with increased vascular and inflammatory placental pathologic findings. METHODS The findings of the present study are a secondary analysis of data generated from a previously reported randomized controlled trial (RCT), the Kellogg Vitamin D Pregnancy Study. Pregnant women (n = 297) in this RCT (January 2013 - April 2018) were randomly assigned to 400 IU vs. 4400 IU vitD/day (10-14 weeks' gestational age) and followed to delivery. 132 placentas were analyzed by pathologists blinded to treatment, and the 2016 Amsterdam Consensus Criteria were used to categorize grouping/grading of placental pathology and weight. Total [25(OH)D] was measured using radioimmunoassay (ng/mL). Chi-square and Student's t-test were used to show the difference in maternal characteristics by treatment group and by placental weight. Chi-square analysis was used to determine differences between the percent pathology findings by treatment group. Students t-test was used to determine the differences in vitD status and the frequency of placental lesions. Association between [25(OH)D] area under the curve (AUC) and placental morphology were determined in a regression model that included maternal BMI ≥ 30 kg/m2, race/ethnicity, and vitD treatment group allocation. Data were analyzed using SAS v9.4 (Cary, NC) and statistical significance was indicated by p < 0.05. RESULTS The percent pathology findings by treatment group were not significantly different for each of the placental pathology categories as defined by the 2016 Amsterdam Consensus Criteria including placental weight. However, when using 25(OH)D as a biomarker for vitD status, linear regression model showed maternal serum [25(OH)D] AUC was significantly associated with greater placental weight (p = 0.023). Logistic regression models showed mothers with BMI ≥ 30 kg/m2 had larger placental weight (p = 0.046), and Hispanic and white/Caucasian mothers had greater placental weights than Black American mothers (p = 0.025). When placentas ≥ 90th % for GA, n = 7, were removed from the placental pool, Pearson correlation still showed a positive association between maternal serum 25(OH)D AUC and placental weight (p = 0.011). In a second linear regression model of placentas ≥ 90th % for GA (n = 7) vs. placentas < 90th % (n = 108), maternal serum 25(OH)D AUC was significantly greater in those placentas ≥ 90th % (p = 0.03); however, this was not associated with increased perinatal mortality. CONCLUSION FINDINGS: suggest increasing maternal serum [25(OH)D] via vitamin D supplementation during pregnancy did not adversely affect placental morphology; trends showed those in the treatment group had fewer placental lesions. Placental weight was found to be significantly associated with [25(OH)D] AUC, which represents maternal vitamin D status over the course of pregnancy; 7 placentas ≥ 90th % for GA were not associated with perinatal mortality.

Abstract
BACKGROUND & AIMS Hypovitaminosis D currently represents a public health problem and is related to the emergence of chronic diseases. Furthermore, this vitamin deficiency has been associated with pregnancy complications, and it can also influence newborn's growth and development. The purpose of this review is to understand the effects of vitamin D nutritional status on women during pregnancy, as well as its impact on newborn's health. METHODS Review of observational studies, published between 2020 and 2021. The research was carried out in the following databases: Pubmed and SciELO. The search terms used to select the articles were: vitamin D, 25(OH)D, serum levels, pregnancy, lactation, gene expression, maternal results, complications, pre-eclampsia, obesity, gestational diabetes, and children. As inclusion criteria, were considered observational studies that addressed the topic and answered the review aims. RESULTS 52 articles were identified and at the end of the selection process, 19 articles were considered, in which they met all the established eligibility criteria. According to the findings in this review, hypovitaminosis D is related to gestational diabetes, pre-eclampsia and gestational weight gain, changes in laboratory parameters as well as outcomes in newborns. CONCLUSIONS Hypovitaminosis D can adversely influence pregnancy and newborn's health, evidencing the need to assess the nutritional status of vitamin D, as well as the existence, or not, of a clinic during pregnancy. It is important that new scientific evidence is published to support this hypothesis.

Abstract
PROBLEM Hyperhomocysteinemia (hypHcy) due to impaired folate metabolism is shown to be a risk factor for preterm birth (PTB) and low birth weight (LBW) in mothers. However, the relationship of fetal hypHcy with adverse pregnancy outcomes is under-represented. The present study aims to investigate the association of fetal hypHcy with oxidative stress and placental inflammation that can contribute to an early breakdown of maternal-fetal tolerance in pre-term birth (PTB). METHODS Cord blood and placenta tissue were collected from PTB and term infant group. Levels of homocysteine, folic acid, vitamin B12 and oxidative stress markers (MDA, T-AOC, 8-OHdG) were measured in cord blood serum using ELISA and respective standard assay kits. Relative expression of candidate genes (TNF-α, IL-6, IL1-β, VEGF-A, MMP2 and MMP9) was also checked using RT-PCR and immunoblotting/immunohistochemistry. RESULTS PTB infants showed significantly higher levels of homocysteine (p = 0.02) and lower levels of vitamin B12 (p = 0.005) as compared to term infants. We also found that PTB infants with hypHcy had lower T-AOC (p = 0.003) and higher MDA (p = 0.04) levels as compared to term infants with normal homocysteine levels. The mRNA and protein levels of TNF-α, VEGF-A, MMP2 and MMP9 were significantly higher in hypHcy PTB infants. CONCLUSION Our results show that fetal hypHcy is associated with oxidative stress and an increase in inflammatory markers in the placenta. Thus, in conclusion, our study demonstrates that fetal hypHcy during pregnancy is a potential risk factor that may initiate an early breakdown of uterine quiescence due to activation of inflammatory processes leading to PTB.

Abstract
OBJECTIVE Vitamin D deficiency in pregnant women is of special concern as mother is the only source of vitamin D for the developing fetus, and maternal hypovitaminosis D has been implicated in a number of maternal and neonatal adverse outcomes. The objective of this study was to assess the association of maternal circulating 25-hydroxy vitamin D3 [25(OH)D] concentration with cord blood 25(OH)D and adverse birth and neonatal outcomes. METHODS This prospective cohort study was conducted in Mahatma Gandhi Medical College and Research Institute (MGMCRI) from January 2020 to December 2020. 121 babies born to mothers with singleton pregnancy tested for serum 25(OH)D level on admission for safe confinement were included in the study and cord blood of the babies were sampled for 25(OH)D. Based on the maternal 25(OH)D level, babies were categorized as those born to mothers with sufficient vitamin D level and those born to mothers with hypovitaminosis D (deficient/insufficient) and primary and secondary outcome was compared between two groups. RESULTS Maternal and cord blood hypovitaminosis D was observed in 65% of mothers and 68.6% of babies, respectively. Maternal vitamin D level was the single most significant predictor of cord blood vitamin D level with five-fold increased risk of cord blood hypovitaminosis D in babies born to mothers with hypovitaminosis D. Birthweight (t = -2.219, p = .028) and preterm birth (aOR = 4.417, 95% CI: 1.03-18.9) was significantly associated with maternal hypovitaminosis D and a trend toward increased risk of LBW (aOR - 2.1, 95%CI: 0.6-7.3), SGA babies (aOR - 1.5, 95% CI: 0.5-4.7), perinatal depression (aOR - 1.5, 95% CI: 0.4-5.8) and neonatal hyperbilirubinemia (aOR = 2.68, 95%CI: 0.942-7.6) was observed. CONCLUSIONS Hypovitaminosis D in pregnant women is a significant health issue affecting both the mother and her baby. Safest dose for supplementation during pregnancy to prevent adverse perinatal outcome needs to be evaluated.

Abstract
A proinflammatory response driven by high-mobility group box 1 (HMGB1) is important for the success of both the early stages of pregnancy and parturition initiation. However, the tight regulation of HMGB1 within these two stages is critical, as increased HMGB1 can manifest into pregnancy-related pathologies. Although during the early stages of pregnancy HMGB1 is critical for the development and implantation of the embryo, and uterine decidualization, high levels within the uterine cavity have been linked to pregnancy failure. In addition, chronic inflammation, resultant from increased HMGB1 within the maternal circulation and gestational tissues, also increases the risk for preterm labor, preterm birth, or infant mortality. Due to the link between HMGB1 and several pregnancy pathologies, the possibility of leveraging HMGB1 as a biomarker has been assessed. However, data are limited that demonstrate how known HMGB1 inhibitors could reduce inflammation within pregnancy. Thus, further research is warranted to improve our understanding of the potential of HMGB1 as a therapeutic target to reduce inflammation within pregnancy. This review aims to describe what is understood about the role of HMGB1 that drives inflammation throughout pregnancy and highlight its potential as a biomarker and therapeutic target within this context.
