Torres A, Cameselle C, Otero P, Simal-Gandara J. The Impact of Vitamin D and Its Dietary Supplementation in Breast Cancer Prevention: An Integrative Review. Nutrients 2024; 16:573. [PMID: 38474702 DOI: 10.3390/nu16050573] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2024] [Revised: 02/09/2024] [Accepted: 02/13/2024] [Indexed: 03/14/2024] Open
Abstract
Vitamin D deficiency is currently a significant public health issue closely linked to numerous diseases, such as breast cancer. This study aims to determine the estimated optimal serum levels of vitamin D to have a protective effect against breast cancer, in addition to exploring the biological mechanisms and risk factors involved. A literature search of articles published in the last 5 years was conducted, and simple statistical analyses using mean and standard deviation were performed to calculate the average concentration of vitamin D from different available studies. It has been observed that serum levels of vitamin D ≥ 40.26 ng/mL ± 14.19 ng/mL could exert a protective effect against breast cancer. Additionally, various biological mechanisms, such as those related to the immune system, and risk factors like diet implicated in this relationship were elucidated. Consequently, it can be concluded that proper serum levels of vitamin D may have a protective effect against breast cancer, and dietary supplementation may be an appropriate procedure to achieve these optimal vitamin D concentrations.

Wimalawansa SJ. Infections and Autoimmunity-The Immune System and Vitamin D: A Systematic Review. Nutrients 2023; 15:3842. [PMID: 37686873 PMCID: PMC10490553 DOI: 10.3390/nu15173842] [Citation(s) in RCA: 9] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2023] [Revised: 08/24/2023] [Accepted: 08/29/2023] [Indexed: 09/10/2023] Open
Abstract
Both 25-autoimmunity and(25(OH)D: calcifediol) and its active form, 1,25-dihydroxyvitamin D (1,25(OH)2D: calcitriol), play critical roles in protecting humans from invasive pathogens, reducing risks of autoimmunity, and maintaining health. Conversely, low 25(OH)D status increases susceptibility to infections and developing autoimmunity. This systematic review examines vitamin D's mechanisms and effects on enhancing innate and acquired immunity against microbes and preventing autoimmunity. The study evaluated the quality of evidence regarding biology, physiology, and aspects of human health on vitamin D related to infections and autoimmunity in peer-reviewed journal articles published in English. The search and analyses followed PRISMA guidelines. Data strongly suggested that maintaining serum 25(OH)D concentrations of more than 50 ng/mL is associated with significant risk reduction from viral and bacterial infections, sepsis, and autoimmunity. Most adequately powered, well-designed, randomized controlled trials with sufficient duration supported substantial benefits of vitamin D. Virtually all studies that failed to conclude benefits or were ambiguous had major study design errors. Treatment of vitamin D deficiency costs less than 0.01% of the cost of investigation of worsening comorbidities associated with hypovitaminosis D. Despite cost-benefits, the prevalence of vitamin D deficiency remains high worldwide. This was clear among those who died from COVID-19 in 2020/21-most had severe vitamin D deficiency. Yet, the lack of direction from health agencies and insurance companies on using vitamin D as an adjunct therapy is astonishing. Data confirmed that keeping an individual's serum 25(OH)D concentrations above 50 ng/mL (125 nmol/L) (and above 40 ng/mL in the population) reduces risks from community outbreaks, sepsis, and autoimmune disorders. Maintaining such concentrations in 97.5% of people is achievable through daily safe sun exposure (except in countries far from the equator during winter) or taking between 5000 and 8000 IU vitamin D supplements daily (average dose, for non-obese adults, ~70 to 90 IU/kg body weight). Those with gastrointestinal malabsorption, obesity, or on medications that increase the catabolism of vitamin D and a few other specific disorders require much higher intake. This systematic review evaluates non-classical actions of vitamin D, with particular emphasis on infection and autoimmunity related to the immune system.

Abstract
The ubiquity of vitamin D metabolising enzymes and vitamin D receptors in mammalian organisms suggests that vitamin D has pleiotropic effects. There are quite a few studies indicating the anticancer, cardioprotective and antidiabetic effects of vitamin D; however, the best-documented actions of vitamin D are the regulation of Ca-phosphate balance and its effect on immune function.Vitamin D levels in organisms are modulated by many environmental and non-environmental factors. One potential factor that may influence vitamin D levels and effects is the sex of the individuals studied. This review focuses on the scientific evidence indicating different synthesis and metabolism of vitamin D in females and males, mainly from PubMed database sources. The article verifies the sex differences in vitamin D levels reported around the world. Moreover, the different effects of vitamin D on the musculoskeletal, cardiovascular, nervous and immune systems, as well as cancer in males and females, were discussed.Most studies addressing sex differences in vitamin D levels and effects are observational studies with conflicting results. Therefore, carefully designed clinical trials and experiments on animal models should be carried out to determine the role of non-environmental factors that may differentiate vitamin D levels in females and males.

Influence of vitamin D levels on outcomes and nosocomial COVID-19 infection in patients undergoing total knee arthroplasty- a cohort study. J Orthop 2022; 34:8-13. [PMID: 35935447 PMCID: PMC9344734 DOI: 10.1016/j.jor.2022.07.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/05/2022] [Accepted: 07/28/2022] [Indexed: 12/01/2022] Open
Abstract
Purpose This study aimed to audit the effects of vitamin D3 on the early functional outcomes, the incidence of nosocomial COVID-19 infection and complications in patients undergoing elective Total Knee Arthroplasty (TKA). Methods This was a retrospective study involving patients undergoing primary unilateral TKA between January 2020 to May 2021 operated by a single surgeon using a single implant. Participants were divided into two cohorts, Deficient-vitamin D3 level <20 ng/ml and Sufficient-vitamin D3 level ≥20 ng/ml. Assessment for Knee Society Score and Oxford Knee Score (OKS) was done preoperatively and one year after TKA. Nosocomial COVID-19 infection rate, 30-day re-admissions and complications were noted during the study. Results 235 patients were divided into 2 cohorts matched by age, gender and ASA grades. 74 patients belonged to the deficient group and 161 belonged to the sufficient group. The mean preoperative scores in the sufficient group were higher than the deficient group (OKS = 15.74 vs 12.95; KSS = 88.91vs 85.62). Similarly, the one-year postoperative scores in the sufficient group were significantly higher (OKS = 36.54 vs 35.16; KSS = 164.01 vs 161.22). A linear correlation was present between preoperative score (r = 0.273) & post-operative scores (r = 0.141) with serum vitamin D3 levels. Vitamin D3 deficient individuals had higher nosocomial COVID-19 infection rate (10.81% vs 4.96%,p = 0.16). The incidence of complications like DVT, embolism, stroke, infection and fracture were not statistically different in the two groups. Conclusion Vitamin D positively influences the outcomes of TKA and protects against nosocomial COVID-19 infection in patients undergoing elective TKA.

Abstract
Vitamin D may be important for neuroprotection after traumatic brain injury (TBI) by modifying the inflammatory response. The objective of this study was to evaluate the association between vitamin D deficiency and functional and survival outcomes in patients with TBI and intracranial injury. This study was a prospective multi-center cohort study conducted on adult TBI patients, with intracranial hemorrhage or diffuse axonal injury confirmed by radiological examination, admitted to five participating emergency departments (EDs) from December 2018 to June 2020. The study outcomes were good functional recovery at hospital discharge and survival at 6-months after injury. The primary exposure was serum vitamin D deficiency (0-10 ng/mL). Multi-level logistic regression analysis was performed to estimate the association between vitamin D deficiency and the study outcomes. Among 606 patients, 101 (16.7%) patients had vitamin D deficiency at the time of ED arrival. Good functional recovery was observed in 65.2% (395/606) of total population, and this proportion was significantly lower in the vitamin D deficiency group than the non-deficiency group (56.4 vs. 66.9%, p = 0.04, adjusted odds ratio (OR; 95% confidence interval [CI]): 0.56 (0.36-0.88)). Overall survival rate at 6 months after injury was 79.5% (434/546), and patients with vitamin D deficiency had significantly lower likelihood of survival at 6 months than patients without deficiency [75.0 vs. 80.3%, adjusted OR (95% CI): 0.59 (0.39-0.89)]. Vitamin D deficiency is associated with poor functional outcomes at hospital discharge and mortality at 6-months after injury in TBI patients with intracranial hemorrhage or diffuse axonal injury.

Dembitsky VM. In Silico Prediction of Steroids and Triterpenoids as Potential Regulators of Lipid Metabolism. Mar Drugs 2021; 19:650. [PMID: 34822521 PMCID: PMC8618826 DOI: 10.3390/md19110650] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2021] [Revised: 11/12/2021] [Accepted: 11/19/2021] [Indexed: 12/12/2022] Open
Abstract
This review focuses on a rare group of steroids and triterpenoids that share common properties as regulators of lipid metabolism. This group of compounds is divided by the type of chemical structure, and they represent: aromatic steroids, steroid phosphate esters, highly oxygenated steroids such as steroid endoperoxides and hydroperoxides, α,β-epoxy steroids, and secosteroids. In addition, subgroups of carbon-bridged steroids, neo steroids, miscellaneous steroids, as well as synthetic steroids containing heteroatoms S (epithio steroids), Se (selena steroids), Te (tellura steroids), and At (astatosteroids) were presented. Natural steroids and triterpenoids have been found and identified from various sources such as marine sponges, soft corals, starfish, and other marine invertebrates. In addition, this group of rare lipids is found in fungi, fungal endophytes, and plants. The pharmacological profile of the presented steroids and triterpenoids was determined using the well-known computer program PASS, which is currently available online for all interested scientists and pharmacologists and is currently used by research teams from more than 130 countries of the world. Our attention has been focused on the biological activities of steroids and triterpenoids associated with the regulation of cholesterol metabolism and related processes such as anti-hyperlipoproteinemic activity, as well as the treatment of atherosclerosis, lipoprotein disorders, or inhibitors of cholesterol synthesis. In addition, individual steroids and triterpenoids were identified that demonstrated rare or unique biological activities such as treating neurodegenerative diseases, Alzheimer's, and Parkinson's diseases with a high degree of certainty over 95 percent. For individual steroids or triterpenoids or a group of compounds, 3D drawings of their predicted biological activities are presented.

Periodontal Disease and Vitamin D Deficiency in Pregnant Women: Which Correlation with Preterm and Low-Weight Birth? J Clin Med 2021; 10:jcm10194578. [PMID: 34640596 PMCID: PMC8509337 DOI: 10.3390/jcm10194578] [Citation(s) in RCA: 28] [Impact Index Per Article: 9.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2021] [Revised: 09/28/2021] [Accepted: 09/29/2021] [Indexed: 01/13/2023] Open
Abstract
Periodontal disease seems to be correlated with low vitamin D serum levels, preterm birth (PTB) and low birth weight (LBW), although the literature still lacks a consensus. This study aimed to investigate this correlation in a cohort of pregnant women over 20 weeks of gestation from the University Hospital “Maggiore della Carità”, Novara, Italy. We assessed serum levels of vitamin D and oral health status through the following indexes: Oral Hygiene Index (OHI), Plaque Control Record (PCR), Gingival Bleeding Index (GBI), and Community Periodontal Index of Treatment Needs (CPTIN). Moreover, we assessed the number of PTB and LBW among the newborns. Out of 121 pregnant women recruited, 72 (mean age 29.91 ± 3.64 years) were included. There was a statistically significant correlation between preterm and OHI > 3 (p = 0.033), and between LBW and OHI > 3 (p = 0.005) and CPITN = 3 (p = 0.027). Both pregnant women with vitamin D deficiency ((25-hydroxy-vitamin D) < 30 ng/mL) and PTB plus LBW newborns were significantly correlated (p < 0.05) with poor levels of all oral health status indexes during pregnancy. Furthermore, these conditions (women with hypovitaminosis D and combination of PTB and LBW) were shown to be significantly correlated (p < 0.001). Taken together, our findings reported a high prevalence of PTB and LBW with poor oral health and vitamin D deficiency in pregnant women.

Effects of Calcium and Vitamin D Co-supplementation on the Lipid Profile: A Systematic Review and Meta-analysis. Clin Ther 2021; 43:274-296. [PMID: 34456059 DOI: 10.1016/j.clinthera.2021.07.018] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2021] [Revised: 06/22/2021] [Accepted: 07/22/2021] [Indexed: 11/26/2022]
Abstract
PURPOSE Calcium and vitamin D co-supplementation is common and widely used, but randomized, controlled trials (RCTs) have yielded inconclusive results concerning its impact on the serum lipid profile. METHODS A comprehensive literature search of Medline, Web of Science, Scopus, Embase, Cochrane Central Register of Controlled Trials, and clinical trial registry databases was conducted to identify placebo-controlled RCTs that were published through September 2020 and that evaluated the impact of calcium and vitamin D co-supplementation on total cholesterol (TC), triglycerides (TGs), low- and very-low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol (HDL-C). Standardized mean differences (SMDs) were pooled using random-effects meta-analysis models. FINDINGS Thirteen studies in a total of 2304 participants met the inclusion criteria. Calcium and vitamin D co-supplementation was associated with significant reductions in both TC (SMD, -0.81; 95% CI, -1.35 to -0.27; I2 = 94.6%) and TGs (SMD, -0.50; 95% CI, -0.91 to -0.08; I2 = 91.5%), and with a significant increase in HDL-C (SMD, 1.22; 95% CI, 0.60 to 1.83; I2 = 95.4%). However, calcium and vitamin D co-supplementation were not found to be associated with significantly decreased low-density lipoprotein cholesterol (SMD, -0.39; 95% CI, -0.78 to 0.01; I2 = 90.1%) or very-low-density lipoprotein cholesterol (SMD, -0.01; 95% CI, -0.70 to 0.69; I2 = 82.3%). IMPLICATIONS The findings from the present systematic review and meta-analysis suggest that calcium and vitamin D co-supplementation has a beneficial effect on TC, TG, and HDL-C. Larger-scale, well-designed RCTs are needed to clarify the effect of calcium and vitamin D co-supplementation on all lipid-profile components.

Relationship between vitamin D status in the first trimester of the pregnancy and gestational weight gain: a mediation analysis. Arch Gynecol Obstet 2021; 305:495-504. [PMID: 34333703 DOI: 10.1007/s00404-021-06163-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2020] [Accepted: 07/27/2021] [Indexed: 12/28/2022]
Abstract
PURPOSE To evaluate the total, and direct effects of vitamin D, measured by circulating 25-hydroxyvitamin D [25(OH)D] levels, on GWG after adjustment for confounding variables, and then assess the indirect effects by demonstrating the role of gestational age at birth as a mediator in this association. METHODS Data collected in "Khuzestan Vitamin D Deficiency Screening Program in Pregnancy" were used for the present study; it included the data of 900 pregnant women referred to the health centers of Shushtar (Khuzestan Province, Iran), whose vitamin D status during the third trimester of pregnancy was available. A mediation analysis was applied to detect the causal relationship between serum level of 25(OH)D, covariates (maternal age, parity, education level, and baseline maternal weight), mediator (gestational age), and outcome (GWG). RESULTS Of 900 pregnant women referred to the health centers, a total of 726 eligible participants were analyzed for the study. The adjusted total effect of vitamin D on GWG was estimated 0.07 (95% CI 0.06, 0.09; P = 0.000). This study also revealed adjusted direct effect of vitamin D on GWG was statistically significant 0.02 (95% CI: 0.003, 0.04; P = 0.021). In addition, the adjusted indirect effect of this micronutrient on GWG by considering gestational age as a mediator was found to be significant [0.05 (95% CI 0.04, 0.06; P = 0.000)]. This study revealed an increase in the trend of weight gain during pregnancy trimesters for women with different levels of 25(OH)D; however, women with severe vitamin D deficiency had the lowest speed as compared to moderate and normal levels. CONCLUSION This study shows that maternal vitamin D status directly affects the gestational weight gain independent of gestational age. Therefore, the detection and treatment of women with vitamin D inadequacy can directly improve the trend of their weight gain in addition to its indirect effect on reducing the risk of preterm delivery.

Abstract
Methods: The prospective study was conducted at the University Hospital from February 2020 to December 2020. The study population (n = 88) included women who later developed PE (n = 42), as well as women who were healthy at birth (n = 46) in the second trimester of pregnancy. Serum levels of CRP, IL-1β, uric acid, creatinine, AST, ALT, MPV, Hb, PC, vitamin D, Ca, and Mg were compared between the groups.Results: Serum IL-1β and uric acid levels were significantly higher in subjects who eventually developed PE compared with those who did not.Conclusions: IL-1β and uric acid may be a predictive markers for PE. Maternal serum IL-1β and uric acid levels in the second trimester of pregnancy may be a predictive markers for PE.

Abstract
Background Although vitamin D3 deficiency is considered as a risk factor for periodontitis, supplementation during periodontal treatment has not been shown to be beneficial to date. Human periodontal ligament cells (hPDLCs) are regulated by vitamin D3 and play a fundamental role in periodontal tissue homeostasis and inflammatory response in periodontitis. The aim of this study is to investigate possible alterations of the vitamin D3 activity in hPDLCs under inflammatory conditions. Methods Cells isolated from six different donors were treated with either 1,25(OH)2D3 (0 to 10 nM) or 25(OH)D3 (0 to 100 nM) in the presence and absence of ultrapure or standard Porphyromonas gingivalis lipopolysaccharide (PgLPS), Pam3CSK4, or interferon‐γ for 48 hours. Additionally, nuclear factor (NF)‐κB inhibition was performed with BAY 11‐7082. The bioactivity of vitamin D in hPDLCs was assessed based on the gene expression levels of vitamin D receptor (VDR)‐regulated genes osteocalcin and osteopontin. Additionally, VDR and CYP27B1 expression levels were measured. Results The vitamin D3‐induced increase of osteocalcin and osteopontin expression was significantly decreased in the presence of standard PgLPS and Pam3CSK4, which was not observed by ultrapure PgLPS. Interferon‐y had diverse effects on the response of hPDLCs to vitamin D3 metabolites. NF‐kB inhibition abolished the effects of standard PgLPS and Pam3CSK4. Standard PgLPS and Pam3CSK4 increased VDR expression in the presence of vitamin D3. CYP27B1 expression was not affected by vitamin D3 and inflammatory conditions. Conclusions This study indicates that the transcriptional activity of VDR is diminished under inflammatory conditions, which might mitigate the effectiveness of vitamin D3 supplementation during periodontal treatment.

Abstract
Diabetic retinopathy (DR) is a form of microangiopathy. Reducing oxidative stress in the mitochondria and cell membranes decreases ischemic injury and end-organ damage to the retina. New approaches are needed, which reduce the risk and improve the outcomes of DR while complementing current therapeutic approaches. Homocysteine (Hcy) elevation and oxidative stress are potential therapeutic targets in DR. Common genetic polymorphisms such as those of methylenetetrahydrofolate reductase (MTHFR), increase Hcy and DR risk and severity. Patients with DR have high incidences of deficiencies of crucial vitamins, minerals, and related compounds, which also lead to elevation of Hcy and oxidative stress. Addressing the effects of the MTHFR polymorphism and addressing comorbid deficiencies and insufficiencies reduce the impact and severity of the disease. This approach provides safe and simple strategies that support conventional care and improve outcomes. Suboptimal vitamin co-factor availability also impairs the release of neurotrophic and neuroprotective growth factors. Collectively, this accounts for variability in presentation and response of DR to conventional therapy. Fortunately, there are straightforward recommendations for addressing these issues and supporting traditional treatment plans. We have reviewed the literature for nutritional interventions that support conventional therapies to reduce disease risk and severity. Optimal combinations of vitamins B1, B2, B6, L-methylfolate, methylcobalamin (B12), C, D, natural vitamin E complex, lutein, zeaxanthin, alpha-lipoic acid, and n-acetylcysteine are identified for protecting the retina and choroid. Certain medical foods have been successfully used as therapy for retinopathy. Recommendations based on this review and our clinical experience are developed for clinicians to use to support conventional therapy for DR. DR from both type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM) have similar retinal findings and responses to nutritional therapies.

Abstract
PURPOSE Vitamin D and calcium insufficiency has been related to elevated blood pressure (BP) and cardiovascular complications. This systematic review and meta-analysis investigates the effect of calcium and vitamin D co-supplementation on BP. METHODS A systematic search was conducted of electronic databases, including Web of Sciences, MEDLINE, Scopus, EMBASE, and the Cochrane Library, along with searches of gray literature and reference lists from included trials. There were no language restrictions, and the databases were searched from inception to October 2019. Randomized controlled trials, using calcium and vitamin D co-supplementation and reporting mean systolic BP and/or diastolic BP (DBP) with SDs, were included in the systematic review. Articles were evaluated independently by 2 researchers based on inclusion and exclusion criteria. A random effects model was conducted to synthesize the data. FINDINGS Eight trials were included in the meta-analysis. Meta-analysis of these 8 trials indicated a nonsignificant reduction in systolic BP in the calcium and vitamin D co-supplementation group compared with control (standardized mean difference, -0.23; 95% CI, -0.52 to 0.06). Conversely, there was a statistically significant decrease in DBP (standardized mean difference, -0.29; 95% CI, -0.55 to -0.02). Subgroup analysis suggested that young adults achieve a greater reduction in DBP than other age groups. IMPLICATIONS Calcium and vitamin D co-supplementation can modulate DBP and should be investigated more specifically in large, well-designed trials of hypertensive populations.

Abstract
CONTEXT No studies have assessed the association between air pollution exposure and vitamin D status in pregnant women. OBJECTIVE To examine the association between particulate air pollution exposure and circulating 25-hydroxyvitamin [25(OH)D] levels in pregnant women. DESIGN A longitudinal cohort study. PARTICIPANTS A total of 3285 pregnant women were recruited at a maternal and child health hospital. INTERVENTIONS None. MAIN OUTCOME MEASURES Serum 25(OH)D levels. RESULTS We observed trimester-specific associations between particulate air pollution exposure and circulating 25(OH)D levels. The associations were most pronounced for the periods of the third trimester and the entire pregnancy. A 10 μg/m3 increase in fine particulate matter (PM2.5) and particulate matter with aerodynamic diameter ≤10 μm (PM10) exposure during the entire pregnancy was associated with a 4.62% (95% CI, -6.31% to -2.93%) and 5.06% (95% CI, -6.50% to -3.62%) decrease in 25(OH)D levels, respectively. Particulate air pollution exposure was also associated with elevated odds of maternal vitamin D deficiency. A 10 μg/m3 increase in PM2.5 and PM10 exposure during the entire pregnancy was associated with a 45% (OR = 1.45, 95% CI, 1.29 to 1.63) and 48% (OR = 1.48, 95% CI, 1.33 to 1.64) increase in the odds of maternal vitamin D deficiency. Mediation analysis estimated that decreased solar UV-B radiation mediated 69.5% and 66.4% of the inverse association between PM2.5 and PM10 exposure and circulating 25(OH)D levels. CONCLUSION Our results suggest that prenatal exposure to particulate air pollution may play an independent role in maternal vitamin D deficiency. The role of air pollution should be incorporated into future guidelines for the prevention of maternal vitamin D deficiency.

Abstract
Rheumatoid arthritis (RA) is a systemic multifactorial autoimmune disorder. The interactions between diverse environmental and genetic factors lead to the onset of this complex autoimmune disorder. Serum levels of vitamin D (VD) are involved in the regulation of various immune responses. Vitamin D is a key signaling molecule in the human body that maintains calcium as well as phosphate homeostasis. It also regulates the functions of the immune system and, thus, can play a substantial role in the etiology of various autoimmune disorders, including RA. Low serum VD levels have been found to be associated with a higher risk of RA, although this finding has not been replicated consistently. The molecular mechanisms by which VD influences autoimmunity need to be further explored to understand how variation in plasma VD levels could affect the pathogenesis of RA. This mini-review focuses on the influence of VD and its serum levels on RA susceptibility, RA-associated complexities, treatment, and transcriptome products of key proinflammatory cytokines, along with other cytokines that are key regulators of inflammation in rheumatoid joints.

Abstract
Vitamin D (VitD) has shown to be beneficial in reversing muscle weakness and atrophy associated with VitD deficiency. Duchenne muscular dystrophy is characterized by worsening muscle weakness and muscle atrophy, with VitD deficiency commonly observed. This study aimed to investigate the effect of VitD supplementation on dystrophic skeletal muscle. Eight-week old female control (C57BL/10; n = 29) and dystrophic (C57BL/mdx; n = 23) mice were randomly supplemented with one of three VitD enriched diets (1000, 8000 & 20,000 IU/kg chow). Following a four-week feeding period, the extensor digitorum longus (EDL) and soleus muscles contractile and fatigue properties were tested ex vivo, followed by histological analysis. As expected, mdx muscles displayed higher mass yet lower specific forces and a rightward shift in their force frequency relationship consistent with dystrophic pathology. There was a trend for mdx muscle mass to be larger following the 20,000 IU/kg diet, but this did not result in improved force production. Fiber area in the EDL was larger in mdx compared to controls, and there were higher amounts of damage in both muscles, with VitD supplementation having no effect. Four weeks of VitD supplementation did not appear to have any impact upon dystrophic skeletal muscle pathology at this age.

Abstract
OBJECTIVE Maternal vitamin D deficiency is an important risk factor that causes infantile rickets in the neonatal and infantile period. The aim of this study was to review the prevalence, clinical characteristics, and treatment of vitamin D deficiency and the follow-ups with infants and their mothers by the neonatal intensive care unit of Afiyet Hospital in Turkey. METHODS Calcium (Ca), phosphorus (P) and 25 (OH) vitamin D were studied and prospectively recorded in infants and their mothers detected to have hypocalcemia during routine biochemistry tests performed on the third postnatal day of the patients follow up and treated with different diagnoses. RESULTS A total of 2,460 infants were admitted into the neonatal intensive care unit between August 2014 and January 2018. Of the infants included in the study, 324 (66.1%) were male and 166 (33.8%) were female, and 366 (74.6%) of them had been delivered by cesarean section (C/S), 124 (25.3%) of them had been delivered by Normal Spontaneous Delivery (NSD). Hypocalcemia was detected in 490 (19.9%) of the infants. In a total of 190 (38.7%) infants and 86 mothers (17.5%), the levels of 25 (OH) vitamin D were found to be below the laboratory detection limit of <3 ng/ml. When vitamin D deficiency + insufficiency is assessed by season, 151 of them were found to be in summer (30.99%), 118 in spring (24.18%), 117 in the winter season(23.87%), and 93 in autumn(18.97%), respectively. There was a statistically significant positive correlation of 78.7% between the vitamins D values of the mothers and the infants (p: 0.000, p<0.05). CONCLUSION This study conducted that a positive correlation of between the vitamin D values of the mothers and the infants. In order to prevent maternal vitamin D deficiency, the appropriate dose of prophylaxis providing optimal levels of vitamin D and should be given by according to the levels of 25 (OH) D vitamin during pregnancy.

Steroids 2019; 141:14-22. [PMID: 30414422 DOI: 10.1016/j.steroids.2018.11.001] [Citation(s) in RCA: 26] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/01/2018] [Revised: 10/09/2018] [Accepted: 11/05/2018] [Indexed: 01/05/2023]
Abstract
Neutrophils are components of the innate immune system that participate in controlling infectious diseases through microbicidal mechanisms such as phagocytosis, degranulation and the release of neutrophil extracellular traps (NETs). NETs are DNA structures that are released through the decondensation and spreading of chromatin and the adherence of various proteins, including neutrophil elastase (NE), myeloperoxidase (MPO) and peptidyl arginine deiminase 4 (PDA4). Since NETs recovered after treatment of activated polymorphonuclear neutrophils can enhance IL-1β and IFN-α production by LPS-activated macrophages, they are thought to be keys to the host's defenses and inflammation. 1,25(OH)2D3 has been shown to play an important role in modulating neutrophils activation and in preventing infections. Therefore, the aim of this study was to assess the effect of 1,25(OH)2D3 in modulating induction of the release of NETs and in regulating the transcription of genes whose products in human neutrophils are NETs-associated proteins, TLRs and interferon. We observed that 1,25(OH)2D3 induced production of NETs-like structures while also upregulating NE/PAD4/COX-3/GAPDH mRNA levels. Additionally, we found an increase in TLR7 and type I interferon (IFN) mRNA levels as a result of neutrophil activation by 1,25(OH)2D3. Since the transcription of genes whose products constitute NETs-associated proteins are differentially-regulated by 1,25(OH)2D3, we proposed that this might restrict the spread of pathogens, such as virus, by inducing NETs, the expression of TLR7 and secretion of IFN-α. Our results suggest the potential importance of this hormone in preventing infections by inducing NETs formation.

Abstract
The role of serum vitamin D (Vit D) in cardiometabolic and muscle health remains unclear. The study aimed to evaluate associations of Vit D and factors of healthy aging among community-living middle-aged and older people in Taiwan. Analytic data on 1839 community-living older adults were excerpted from I-Lan Longitudinal Aging Study. All participants were collected demographic characteristics, serum Vit D, functional assessment, and cardiometabolic risk factors. The prevalence of Vit D insufficiency and deficiency in this study was 50.5% and 33.6%, respectively. Among 617 participants with Vit D deficiency, 72.3% of them were women. In multivariate logistic regression, the independent risk factors of Vit D deficiency were male gender (odds ratio [OR]: 0.266; 95% confidence interval [CI]: 0.213-0.333; P < 0.001), higher BMI (OR: 1.036; 95% CI: 1.005-1.067; P = 0.022), high total cholesterol (OR: 1.437; 95% CI: 1.160-1.779; P = 0.001), and high triglyceride (OR: 1.865; 95% CI: 1.446-2.404; p < 0.001). In multinomial logistic regression for 3-level Vit D status analysis, similar trend was found among participants with Vit D insufficiency. Insulin resistance increased in 2.31 and 1.71-folds in Vit D deficiency and insufficiency groups. Besides, association between Vit D deficiency and osteopenia was found only in women. In conclusion, Vit D deficiency was more common in women, and associated with poorer musculoskeletal health and higher cardiovascular and metabolic risk, including higher BMI, DBP, insulin resistance, total cholesterol, and triglyceride.

Abstract
Objective: This systematic review and meta-analysis of Spanish studies assessed the association of maternal 25-hydroxyvitamin D [25(OH)D] levels on perinatal outcomes. Methods: PubMed, Cochrane Library, Embase, Scielo, Scopus, and Web of Science research databases were searched from inception through December 30 2017 using the terms 'vitamin D', 'pregnancy', and 'Spain'. Studies that compared first or second half of pregnancy normal 25(OH)D (≥30.0 ng/mL) versus insufficient (20.0-29.9 ng/mL) or deficient (<20.0 ng/mL) circulating levels and perinatal outcomes were systematically extracted. Data are presented as pooled odds ratios and their 95% confidence intervals (CIs) for categorical variables or mean differences and CIs for continuous variables. Risk of bias was evaluated with the Newcastle-Ottawa Scale. Results: Five cohort studies met inclusion criteria. The risk of gestational diabetes mellitus, preeclampsia, preterm birth, and small-for-gestational-age infants, and birthweight was not influenced by first half of pregnancy maternal 25(OH)D levels. In addition, second half of pregnancy 25(OH) levels did not affect birthweight. Conclusion: Maternal 25(OH)D levels during pregnancy did not affect studied perinatal outcomes and birthweight.

Abstract
BACKGROUND AND AIM Increasing prevalence of neonatal sepsis in recent years catch attention to early prevention and management. Vitamin D receptor (VDR) polymorphism can modulate VDR expression level that greatly influences immunity and susceptibility to microbial infections. We aimed to investigate the association of VDR polymorphism at FokI, rs2228570 T/C, and TaqI, rs731236 C/T gene with serum 25-hydroxyvitamin D level and risk of neonatal sepsis. METHODS This work carried on 160 subjects classified into 80 cases (40 mothers and their 40 septic neonates) and 80 healthy controls (40 volunteer mothers and their 40 healthy neonates). Genotyping of VDR polymorphisms were assayed by real-time PCR and serum 25-hydroxyvitamin D level and hs-CRP were measured by ELISA. RESULTS Vitamin D deficiency was observed in mothers of cases compared with healthy ones (p = <0.001) and in septic neonates versus healthy ones (p = <0.001). Septic neonates had much higher VDR FokI TT genotype (p = 0.014) and T allele (p = 0.003) versus healthy ones. TT genotype and T allele could increase the risk of sepsis with OR 95% CI [4.804 (1.4-16.4)] and [2.786 (1.4-5.7)] respectively while VDR TaqI showed no association with sepsis. There was a strong LD between FokI and TaqI in sepsis cases. In sepsis, T/T genotype at FokI had significantly lower vitamin D (p = <0.001). CONCLUSION Vitamin D deficiency in mothers/neonates is a risk factor for neonatal sepsis. VDR FokI T allele had lower 25-hydroxyvitamin D level that may predispose to sepsis hazards.

Abstract
Vitamin D supplementation effects with or without calcium in pregnancy for reducing risk of preeclampsia and gestational or pregnancy induced hypertension are controversial. Literature was systematically searched in Medline, Scopus and Cochrane databases from inception to July 2017. Only randomized controlled trials (RCTs) in English were selected if they had any pair of interventions (calcium, vitamin D, both, or placebo). Systematic review with two-step network-meta-analysis was used to indirectly estimate supplementary effects. Twenty-seven RCTs with 28,000 women were eligible. A direct meta-analysis suggested that calcium, vitamin D, and calcium plus vitamin D could lower risk of preeclampsia when compared to placebo with the pooled risk ratios (RRs) of 0.54 (0.41, 0.70), 0.47 (0.24, 0.89) and 0.50 (0.32, 0.78), respectively. Results of network meta-analysis were similar with the corresponding RRs of 0.49 (0.35, 0.69), 0.43 (0.17, 1.11), and 0.57 (0.30, 1.10), respectively. None of the controls were significant. Efficacy of supplementation, which was ranked by surface under cumulative ranking probabilities, were: vitamin D (47.4%), calcium (31.6%) and calcium plus vitamin D (19.6%), respectively. Calcium supplementation may be used for prevention for preeclampsia. Vitamin D might also worked well but further large scale RCTs are warranted to confirm our findings.

Abstract
BACKGROUND In addition to its well-established role in maintaining skeletal health, vitamin D has essential regulatory functions in female reproductive and pregnancy outcomes. Phthalates and bisphenol A (BPA) are endocrine disruptors, and previous research has suggested that these chemical agents may disrupt circulating levels of total 25(OH)D in adults. OBJECTIVES We investigated the relationships between repeated measures of urinary phthalate metabolites and BPA and circulating total 25(OH)D in a prospective cohort of pregnant women. METHODS The present study population includes participants (n=477) in a nested case-control study of preterm birth drawn from a prospective birth cohort of pregnant women at Brigham and Women's Hospital in Boston, Massachusetts. Urine and blood samples were collected for biomarker measurements at median 10 wk and 26 wk of gestation. RESULTS In repeated measures analysis, we observed that an interquartile range (IQR) increase in urinary mono-3-carboxypropyl phthalate (MCPP) was associated with a 4.48% decrease [95% confidence interval (CI): -7.37, -1.58] in total 25(OH)D. We also detected inverse associations for metabolites of di(2-ethylhexyl) phthalate (DEHP) [percent difference (%Δ)=-2.83 to -2.16]. For BPA, we observed a nonsignificant inverse association with total 25(OH)D in the overall population. Our sensitivity analysis revealed that the associations for some metabolites (e.g., MEHP) varied by race/ethnicity, which may reflect potential differences in susceptibility. In agreement with findings from repeated measures analysis, we reported that DEHP metabolites and BPA were significantly associated with an approximate 20% increase in the odds of vitamin D deficiency (≤20 ng/mL) [odds ratio (95% CI): 1.19 (1.06, 1.35) for molar sum of DEHP metabolites and 1.22 (1.01, 1.47) for BPA] at median 10 wk and 26 wk, respectively. CONCLUSIONS Our results provide suggestive evidence of the potential for environmental exposure to phthalates and/or BPA to disrupt circulating vitamin D levels in pregnancy. https://doi.org/10.1289/EHP1178.

Abstract
Background Epidemiological studies have shown an inverse relationship between vitamin D levels and cardiovascular diseases. However, this does not infer a causal relationship between the two. Chronic kidney disease (CKD) patients have a high prevalence of vitamin D deficiency and carotid atherosclerosis. Therefore, in this study we have aimed to determine the association between serum 25-hydroxyvitamin D levels and carotid atherosclerosis in the CKD population. Methods 100 CKD stage 3–4 patients were included in the study. Direct chemiluminesent immunoassay was used to determine the level of serum 25-hydroxyvitamin D. All subjects underwent a carotid ultrasound to measure common carotid artery intima-media thickness (CCA-IMT) and to assess the presence of carotid plaques or significant stenosis (≥50 %). Vitamin D deficiency was defined as serum 25-hydroxyvitamin D < 25 nmol/L. Abnormal CCA-IMT was defined as CCA-IMT ≥ 0.8 mm. Plaque was defined as a focal structure that encroaches into the arterial lumen of ≥ 0.5 mm or 50 % of the surrounding IMT value. Significant stenosis was defined as peak-systolic velocities ≥ 125 cm/s and end-diastolic velocities ≥ 40 cm/s. Results The vitamin D deficiency and non-deficiency groups did not differ significantly in terms of abnormal CCA-IMT (P = 0.443), carotid plaque (P = 0.349), and carotid stenosis (P = 0.554). No significant correlation between serum 25-hydroxyvitamin D levels and CCA-IMT (P = 0.693) was found. On a backward multiple linear regression model, serum 25-hydroxyvitamin D levels was not associated with CCA-IMT, abnormal CCA-IMT, or plaque presence. Conclusions No important association between serum 25-hydroxyvitamin levels and carotid atherosclerosis was found in CKD patients.

Abstract
OBJECTIVE AND METHODS To measure 25-hydroxyvitamin D [25(OH)D] and C-reactive protein (CRP) serum levels in singleton gestations complicated with threatened preterm labour (TPL, n = 59) and compare to normal controls matched for gestational age (n = 64). Cases were treated after blood sample according to institutional protocol. Also, analyte levels were compared among cases according to the outcome. RESULTS Mean serum 25(OH)D levels were similar between cases and controls, with median white blood cell count and CRP levels found significantly higher in TPL cases. Women with TPL delivering preterm displayed shorter mean cervical lengths along with higher CRP and lower 25(OH)D serum levels when compared to those delivering at term. Two multiple linear regression models were constructed to analyse factors related to gestational age at delivery (pooled analysis and only those with TPL). In both models, gestational age positively correlated to cervical length and inversely to CRP levels; whereas, in the TPL model, only 25(OH)D levels correlated positively. CONCLUSION Women complicated with TPL showed similar serum 25(OH)D yet higher CRP levels as compared to controls. TPL cases delivering preterm displayed lower 25(OH)D and higher CRP correlated levels.

Abstract
OBJECTIVE To assess the correlation between serum 25-hydroxy vitamin D [25(OH)D] status and outcomes of in vitro fertilization (IVF) in infertile women through review systematically. METHODS We used Embase, Pubmed, and Cochrane database to identify all studies that assessed the correlation between serum vitamin D levels and IVF outcomes in infertile women up until 30 June 2015, with the restricted language of English. We included studies that compared IVF outcomes between infertile women vitamin D <20 ng/ml and vitamin D ≥20 ng/ml. The results were summarized using Stata 12.0 software. For studies reported dichotomous outcomes (clinical pregnancy rate and live birth rate), we pooled the relative risks ratios (RRs) and 95 % confidence intervals (CIs) in a random effects model. RESULTS Our search resulted in the retrieval and screening of 134 studies. Of those, five studies were included in our meta-analysis. The risk for lower clinical pregnancy rate was not significantly increased in the deficient group (RR 0.88, 95 % CI 0.69-1.11). Lower vitamin D status was associated with lower live birth rate (RR 0.76, 95 % CI 0.61-0.93). CONCLUSION There is no significant correlation between deficient serum vitamin D level and lower clinical pregnancy rate in infertile woman undergoing in vitro fertilization. On the other hand, deficient vitamin D level was related to lower live birth rate.

Abstract
Studies linking vitamin D and long-term metabolic health have generated much debate. Recommendations for the intake of vitamin D by the general public and by the health care professionals have been complicated by a number of inconsistencies in the literature. These caveats relate to the methodological approaches, differences in the populations (and the species) of study, and the definitions used for thresholds of vitamin D status. This review addresses current evidence available for assessing the potential programming of long-term metabolic health of offspring by maternal vitamin D status in pregnancy. It summarizes knowledge on the early origins of metabolic health and analyzes evidence for an association between the vitamin D status in pregnancy and maternal and fetal health status. In addition, we analyze the link between the regulation of inflammation and the vitamin D status in the general population to inform on the general mechanisms through which early vitamin D might affect the programming of long-term health. The evidence suggests an association between the vitamin D status in early life and the programming of long-term health. However, to the best of our knowledge, the current finding is insufficient to draw a final conclusion for evidence-based preventive actions. The data warrant replication in prospective studies and additional research substantiating the causal factors and pathways.

Abstract
Tissue-specific expression of steroidogenic enzymes allows the modulation of active steroid levels in a local manner. Thus, the measurement of local steroid concentrations, rather than the circulating levels, has been recognized as a more accurate indicator of the steroid action within a specific tissue. Adipose tissue, one of the largest endocrine tissues in the human body, has been established as an important site for steroid storage and metabolism. Locally produced steroids, through the enzymatic conversion from steroid precursors delivered to adipose tissue, have been proven to either functionally regulate adipose tissue metabolism, or quantitatively contribute to the whole body's steroid levels. Most recently, it has been suggested that adipose tissue may contain the steroidogenic machinery necessary for the initiation of steroid biosynthesis de novo from cholesterol. This review summarizes the evidence indicating the presence of the entire steroidogenic apparatus in adipose tissue and discusses the potential roles of local steroid products in modulating adipose tissue activity and other metabolic parameters.

Abstract
UNLABELLED Vitamin D facilitates calcium absorption and bone building. Presence of vitamin D is highly important in pregnant women due to its effect on the development of the fetal skeleton. The study population comprised 208 low-risk pregnant women of a heterogeneous population. Maternal and fetal serum concentrations of vitamin D were measured using the Liaison 25(OH)D Assay (DiaSorin, Italy). CONCLUSION Maternal vitamin D serum concentrations correlate with neonatal vitamin D serum concentrations but do not affect neonatal weight and/or head circumference. WHAT IS KNOWN? • Vitamin D is known to be also involved in immunomodulation and cellular proliferation and differentiation. • Vitamin D is highly important in pregnant women for its effect on fetal musculoskeletal and neurological development. WHAT IS NEW? • No association was detected between maternal or neonatal vitamin D concentration with neonatal growth parameters or obstetrical complications, and no association was found between maternal vitamin D serum concentrations and maternal obstetrical complication rate. • A strong correlation was demonstrated between maternal and neonatal serum vitamin D concentrations.

Abstract
Respiratory distress syndrome (RDS) and bronchopulmonary dysplasia (BPD) are major complications to preterm birth. Hypovitaminosis D is prevalent in pregnancy. We systematically reviewed the evidence of the impact of vitamin D on lung development, surfactant synthesis, RDS, and BPD searching PubMed, Embase, and Cochrane databases with the terms vitamin D AND (surfactant OR lung maturation OR lung development OR respiratory distress syndrome OR fetal lung OR prematurity OR bronchopulmonary dysplasia). Three human studies, ten animal studies, two laboratory studies, and one combined animal and laboratory study were included. Human evidence was sparse, allowing no conclusions. BPD was not associated with vitamin D receptor polymorphism in a fully adjusted analysis. Animal and laboratory studies showed substantial positive effects of vitamin D on the alveolar type II cell, fibroblast proliferation, surfactant synthesis, and alveolarization. These data support the hypothesis of hypovitaminosis D as a frequent, modifiable risk factor of RDS and BPD, which should be tested in randomized controlled trials on pregnant women, those with threatening preterm delivery, or in the preterm neonates. Future experimental and human studies should aim to identify optimal time windows, vitamin D doses, and cut-off levels for 25-hydroxyvitamin D in interventions against RDS, BPD, and later adverse respiratory outcomes.

Abstract
BACKGROUND Vitamin D receptors have been identified in the spinal cord, nerve roots, dorsal root ganglia and glial cells, and its genetic polymorphism association with the development of lumbar disc degeneration and herniation has been documented. Metabolic effects of active vitamin D metabolites in the nucleus pulposus and annulus fibrosus cells have been studied. Lumbar disc herniation is a process that involves immune and inflammatory cells and processes that are targets for immune regulatory actions of vitamin D as a neurosteroid hormone. In addition to vitamin D's immune modulatory properties, its receptors have been identified in skeletal muscles. It also affects sensory neurons to modulate pain. In this study, we aim to study the role of vitamin D3 in discogenic pain and related sensory deficits. Additionally, we will address how post-treatment 25-hydroxy vitamin D3 level influences pain and sensory deficits severity. The cut-off value for serum 25-hydroxy vitamin D3 that would be efficacious in improving pain and sensory deficits in lumbar disc herniation will also be studied. METHODS/DESIGN We will conduct a randomized, placebo-controlled, double-blind clinical trial. Our study population will include 380 cases with one-level and unilateral lumbar disc herniation with duration of discogenic pain less than 8 weeks. Individuals who do not have any contraindications, will be divided into three groups based on serum 25-hydroxy vitamin D3 level, and each group will be randomized to receive either a single-dose 300,000-IU intramuscular injection of vitamin D3 or placebo. All patients will be under conservative treatment. Pre-treatment and post-treatment assessments will be performed with the McGill Pain Questionnaire and a visual analogue scale. For the 15-day duration of this study, questionnaires will be filled out during telephone interviews every 3 days (a total of five times). The initial and final interviews will be scheduled at our clinic. After 15 days, serum 25-hydroxy vitamin D3 levels will be measured for those who have received vitamin D3 (190 individuals).

Abstract
BACKGROUND Vitamin D deficiency has become a global health issue in pregnant women. This study aimed to assess the adequacy of maternal vitamin D status by measuring maternal serum and breast milk 25-hydroxyvitamin D [25(OH)D] levels and to determine the association between maternal serum and milk 25(OH)D levels. METHODS Data was obtained from the Universiti Sains Malaysia Pregnancy Cohort Study. This study was conducted from April 2010 to December 2012 in the state of Kelantan, Malaysia. Blood samples from pregnant women aged 19 to 40 years were drawn in the second and third trimesters of pregnancy, while breast milk samples at delivery, 2, 6 and 12 months postpartum were collected to analyze for 25(OH)D levels. A total of 102 pregnant women were included in the analysis. RESULTS Vitamin D deficiency [25(OH)D <50 nmol/L] was detected in 60% and 37% of women in the second and third trimesters of pregnancy, respectively. There were 6% and 23% of women who reached normal level of vitamin D status in the second trimester and the third trimester, respectively. Multivitamin intakes during pregnancy were significantly associated with higher serum 25(OH)D levels in the second trimester (β = 9.16, p = 0.005) and the third trimester (β = 13.65, p = 0.003). 25(OH)D levels in breast milk during the first year of lactation ranged from 1.01 to 1.26 nmol/L. Higher maternal serum 25(OH)D level in the second trimester of pregnancy was associated with an elevated level of 25(OH)D in breast milk at delivery (β = 0.002, p = 0.026). CONCLUSIONS This study shows that high proportions of Malay pregnant women are at risk of vitamin D deficiency. Maternal vitamin D status in the second trimester of pregnancy was found to influence vitamin D level in breast milk at delivery.

Abstract
Vitamin D deficiency may be a risk factor for negative outcome in pregnancy, such as pre-term labour, low birthweight, intrauterine growth retardation and gestational diabetes. This study aimed to evaluate the relationship between vitamin D and pre-eclampsia. This was a case-control study of 59 pre-eclamptic women and 59 healthy pregnant women selected in two hospitals in Ahvaz, Iran. Women with term singleton pregnancy, nulliparous and of reproductive age were selected. Venous blood samples (2 mL) were taken and the level of 25-dihydroxy vitamin D (25-OH-D) was measured. If the levels of 25-OH-D were less than 10 ng mL(-1), between 10 ng mL(-1) and 29 ng mL(-1) and more than 30 ng mL(-1), they were considered as indicating deficient, insufficient and normal 25-OH-D concentrations, respectively. The independent t-test, Mann-Whitney U-test, chi-square and logistic regression were used for analysing the data. Vitamin D deficiency was significantly higher in the pre-eclampsia group [odds ratio (OR) = 24.04, confidence interval (CI) = 2.10-274.8, P = 0.01]. Older women (30-35 years) were more likely to develop pre-eclampsia compared with the control group (OR = 10.36, CI = 2.18-49.09, P = 0.003). The results showed that women with body mass index (BMI) <20 were more likely to develop pre-eclampsia. The ages between 20 years and 30 years and normal BMI were not the risk factors for pre-eclampsia. Vitamin D deficiency has a statistically significant relationship with pre-eclampsia. It seems that the serum vitamin D levels are low in Iranian women because of their particular lifestyle and they may need more than 400 IU day(-1) vitamin D supplement during pregnancy.

Abstract
There is increasing interest in vitamin D nutrition during pregnancy because of widespread reports of a high prevalence of low vitamin D status in pregnant women. While vitamin D is important for calcium and phosphorus homeostasis and for bone health, it also plays important roles in many other physiologic functions in the body. Consistent with the expanded role of vitamin D, recent observational studies have demonstrated that low vitamin D status in pregnancy is associated with multiple potential adverse maternal, fetal, and infant outcomes and contributes to low vitamin D status in infants at birth. Therefore, an overview of the current understanding of vitamin D nutrition in pregnancy and a review of the results of studies to optimize vitamin D status during pregnancy and in the offspring is of public health importance and timely.

Abstract
Repeated implantation failure (RIF) is a worldwide health problem that imposes a great deal of cost on patients and health care system. Vitamin D(3) has been proposed to have positive impact on the process of implantation. The present study was performed to compare the effect of 1,25-dihydroxy vitamin D(3) (1,25(OH)(2)D(3)) on cytokine production by endometrial cells of women with RIF and healthy fertile controls. Whole endometrial cells (WECs) and endometrial stromal cells (ESCs) from RIF and normal fertile women were treated with 1,25(OH)(2)D(3). The levels of IL-10, TGF-β, IFNγ, Il-6, IL-8 and IL-17 in culture supernatants were assayed by ELISA. Also, ability of the cells from both groups to produce 1,25(OH)(2)D(3) was evaluated and compared. 1,25(OH)(2)D(3) down-regulated cytokine production in WECs from both groups except for IL-8 which was upraised. Similar trends were also observed in ESCs except up-regulation of TGF-β in RIF group. Endometrial cells of both groups had comparable capacity to produce 1,25(OH)(2)D(3). Based on the minimal differential immunoregulatory effect of vitamin D(3) on endometrial cells from RIF and control women, it may be suggested that circulating levels of maternal vitamin D(3) be the subject of further investigation.

Abstract
BACKGROUND Vitamin D has been implicated in embryo/placental development and growth; however information in this regard is limited or unavailable. OBJECTIVE To assess 25-hydroxyvitamin D (25(OH)D), free β-human chorionic gonadotropin (β-hCG) and pregnancy associated plasma protein A (PAPP-A) status during pregnancy. METHODS Serum 25(OH)D, β-hCG, and PAPP-A levels were measured in the first trimester of otherwise healthy Spanish pregnant women (n=488). Rho Spearman coefficients were calculated to determine correlations between analytes. RESULTS Median serum 25(OH)D levels for the entire sample was 27.4 ng/ml (interquartile range=12.1). 25(OH)D levels were insufficient (20-29.99 ng/ml) and deficient (<20 ng/ml) in 40.6% and 23.2%, respectively, in relation to ethnics, body mass index values, tobacco use, and season/gestational age at blood sampling. β-hCG and PAPP-A levels significantly correlated (r²=0.47) yet neither of them with 25(OH)D levels. Despite this, the three analytes significantly correlated with gestational age at sampling. CONCLUSION First trimester 25(OH)D, β-hCG, and PAPP-A levels increase with gestational age; however, placental peptides do not correlate with vitamin D levels, suggesting a non-placental 25(OH)D production. More research is required in this regard.

Abstract
In the past few years a growing interest in vitamin D can be observed in the lay and biomedical literature due to findings demonstrating a low vitamin D status in the population. In addition to its importance for the regulation of calcium and phosphorus homeostasis recent epidemiologic studies have observed relationships between low vitamin D levels and multiple disease states. This secosteroid hormone also regulates the expression of a large number of genes in reproductive tissues implicating a role for vitamin D in female reproduction. In this report we summarize the recent evidence that vitamin D status influences female reproductive and pregnancy outcomes. Human and animal data suggest that low vitamin D status is associated with impaired fertility, endometriosis and polycystic ovary syndrome. Evidence from observational studies shows higher rates of preeclampsia, preterm birth, bacterial vaginosis and gestational diabetes in women with low vitamin D levels. However, confirmation of experimental observations establishing an association of vitamin D deficiency with adverse reproductive outcomes by high quality observational and large-scale randomized clinical trials is still lacking. The determination of optimal 25(OH)D3 levels in the reproductive period and the amount of vitamin D supplementation required to achieve those levels for the numerous actions of vitamin D throughout a woman's life would have important public health implications.

Abstract
OBJECTIVE To determine the pregnancy outcome as a function of the first-trimester serum 25-hydroxyvitamin D(3) [25(OH)D] status and to compare the 25(OH)D levels in the first and third trimesters. METHODS Pregnant women (n=466) tested for serum 25(OH)D levels during the first trimester were followed up until the end of pregnancy, and the obstetric and neonatal outcomes were compared in reference to the baseline 25(OH)D status. The third-trimester 25(OH)D levels were additionally measured in a subset of women (n=148). RESULTS The obstetric and neonatal outcomes did not vary as a function of the first-trimester 25(OH)D status. Neither did the 25(OH)D levels vary as a function of pregnancy outcomes. Overall, the 25(OH)D levels significantly decreased from the first to the third trimester. The first- and third-trimester 25(OH)D levels of samples initially taken during autumn/winter were significantly lower than those that were initially taken during spring/summer. Interestingly, the decrease in 25(OH)D levels during the third trimester was independent of the season of sampling. CONCLUSION The pregnancy outcome was independent of the first-trimester 25(OH)D status. Overall, the 25(OH)D levels significantly decreased in the third trimester. More research in this area is warranted.
