Background: Early-onset neonatal sepsis (EOS) is a systemic infection that occurs within the first week of life. Objectives: This study investigated the association of serum vitamin D levels in pregnant women and their neonates with the prevalence of EOS. Methods: This case-control study was performed among 50 term/late pre-term neonates admitted to our NICU due to EOS, alongside 50 healthy neonates matched for gestational age range and sex. Maternal and neonatal serum vitamin D levels were measured. The criteria for diagnosing EOS included any/combination of: respiratory, cardiovascular, hemodynamic, neurological, gastrointestinal, body temperature, or metabolic signs. For sepsis cases, CBC, CRP, blood type, blood culture, chest X ray, and in some cases, and CSF analysis and culture were tested. Mothers’ clinical history was collected. Results: Each group included 30 (60%) male and 20 (40%) female neonates. Birth weight averages were 2772 ± 667 and 3215 ± 349 grams in the case and control groups, respectively (P < 0.001). The mean serum vitamin D levels were 49.75 ± 25.53 and 56.41 ± 18.17 nmol/L in the case and control groups, respectively. The control group mothers had a significantly higher vitamin D level (68.24 nmol/L versus 55.01 in mothers of sepsis cases, p=0.005) and showed a correlation with the vitamin D levels of their neonates (R = 0.731, P < 0.001), while the data failed to show a correlation between vitamin D level in mothers and their neonates in the sepsis group (R = 0.241, P = 0.115). C-section delivery was more prevalent among the sepsis cases (P < 0.001). Conclusions: Early-onset neonatal sepsis is associated with vitamin D deficiency in neonates and their mothers, low birth weight, and being delivered by C-section.

Objective. The main goal of our study was to assess relationships between first trimester 25-hydroxyvitamin D3 levels and infant birthweight and length at birth. Materials and Methods. We conducted a study over our medical records of 154 live-term births at Acibadem Atakent Hospital, Istanbul, Turkey. Subjects were classified into five independent groups. Results. We retrospectively reviewed a total of 154 live birth records. They took vitamin D3 supplement 1000 U/day. We classified the serum vitamin D levels into 5 groups by concentration. Group 1 comprised serum vitamin D levels <10 ng/ml (n = 41); group 2 comprised serum Vitamin D levels between >10–16 ng/ml (n = 33); group 3 comprised serum vitamin D levels >16–20 ng/ml (n = 26); group 4 vitamin D level between >20–30 ng/ml (n = 33) and group 5 comprised vitamin D levels >30 ng/ml. The femurs of infants were found to be longer between the groups, although the differences were not significant (p=0.054). There was also a statistically significant difference in the neonatal birth weight (p=0.048). Conclusion. We observed associations between low and high maternal 25-hydroxyvitamin D3 levels and fetal growth at birth weight but no difference in birth length. We conclude that we always need to conduct further research to be able to predict the effects of vitamin D deficiency.

Background: Vitamin D has been shown to have an immunomodulatory effect, and previous studies have proven that vitamin D deficiency contributed to several autoimmune diseases, including psoriasis. Purpose: The purpose of this study was to determine serum vitamin D levels in psoriasis vulgaris patients and compare them with control subjects. Methods: The research samples were sixteen adults with psoriasis vulgaris and 16 control subjects. Blood samples were taken, and the serum 25 (OH) D levels were measured using the Chemiluminescent Microparticle Immunoassay method. Result: The mean serum vitamin D in psoriasis vulgaris patients and controls were 14.36 ± 6.36 and 19.92 ± 7.59 ng/mL, respectively. No psoriasis vulgaris were observed in patients with normal 25(OH)D levels, and only 3 control subjects with normal serum 25(OH)D levels. These results were not statistically significant (p = 0.09). Conclusion: Most patients with psoriasis vulgaris were observed having vitamin D deficiency. However, the prevalence of vitamin D deficiency in the control subjects was high as well. Therefore, there were no differences in serum 25(OH)D levels between psoriasis vulgaris and control patients.

ObjectiveTo review the evidence to assess effectiveness of vitamin D supplementation during pregnancy and associations of serum vitamin D levels with perinatal outcomes.DesignOverview of systematic reviews (SRs).Data sourcesSearches conducted in January 2019: Ovid Medline (1946–), Cochrane Library databases.Eligibility criteria for selecting studiesTwo reviewers independently screened titles and abstracts, and full texts using predefined inclusion criteria: SRs evaluating vitamin D supplementation in pregnant women and/or examining the association between serum vitamin D levels reporting at least one predefined perinatal outcome. Only SRs with high AMSTAR scores were analysed.Data extraction and synthesisData were extracted independently by one reviewer and checked by a second. Results were assessed for quality independently by two reviewers using GRADE criteria.ResultsThirteen SRs were included, synthesising evidence from 204 unique primary studies. SRs of randomised controlled trials (RCTs) with the highest level of evidence showed no significant benefit from vitamin D in terms of preterm birth (RR 1.00 (95% CI 0.77, 1.30); high quality), pre-eclampsia (RR 0.91 (0.45, 1.86); low quality), gestational diabetes (RR 0.65 (0.39, 1.08); very low quality), stillbirth (RR 0.75 (0.50, 1.12); high quality), low birth weight (RR 0.74 (0.47, 1.16); low quality), caesarean section (RR 1.02 (0.93, 1.12); high quality). A significant difference was found for small for gestational age (RR 0.72 (0.52, 0.99); low quality). SRs of observational studies showed associations between vitamin D levels and preterm birth (RR 1.19 (1.08, 1.31); moderate quality), pre-eclampsia (RR 1.57 (1.21, 2.03) for 25-hydroxy vitamin D (25 (OH)D)<50 nmol/L subgroup; low quality), gestational diabetes (RR 1.12 (1.02, 1.22) for 25 (OH)D<50 nmol/L and RR 1.09 (1.03, 1.15)<75 nmol/L; moderate quality) and small for gestational age (RR 1.35 (1.18, 1.54)<50 nmol/L; low quality). SRs showed mixed results for associations between vitamin D and low birth weight (very low quality) and caesarean section (very low quality).ConclusionThere is some evidence from SRs of observational studies for associations between vitamin D serum levels and some outcomes; however SRs examining effectiveness from RCTs showed no effect of vitamin D supplementation in pregnancy with the exception of one predefined outcome, which had low quality evidence. Credibility of the evidence in this field is compromised by study limitations (in particular, the possibility of confounding among observational studies), inconsistency, imprecision and potential for reporting and publication biases.

The Relationship

Background: An observational study was undertaken to study the relationship between maternal serum vitamin D levels during peripartum period and neonatal birth weight.Methods: This study was done on 569 patients to study the relationship between maternal serum vitamin D levels during peripartum period and neonatal birth weight. The data included was maternal serum samples (taken during peri-partum period) and neonatal birth weight. The primary objective of this project was to assess the vitamin D levels in maternal serum and to study its relationship, if any, with birth weight in the neonates.Results: A total of 569 samples of maternal serum were analyzed for serum 25(OH)D levels out of which 457(80%) mothers were found to have sufficient, 101(18%) insufficient and 11(2%) deficient Vitamin D levels as per US Endocrinological society guidelines. Out of total 569 newborns, 104 (18.27%) were low birth weight (LBW) and 465 (81.27%) were normal birth weight (NBW). Out of total LBW (104), 19(18.27%) were born to vitamin D deficient (VDD) mothers and 85 (81.72%) were born to vitamin D sufficient (VDS) mothers. Out of total NBW(465), 86(18.45%) were born to VDD mothers and 379 (81.17%) were born to VDS mothers. These results were not statistically significant (p=0.76456749).Conclusions: Maternal 25(OH)-vitamin D status during late pregnancy did not have any statistically significant effect on the neonatal birth weight.

Neonatal Growth

Low vitamin D levels during pregnancy may account for reduced fetal growth and for altered neonatal development. The present study explored the association between maternal vitamin D status measured early in pregnancy and birth weight, prevalence of small-for-gestational-age (SGA) infants and postnatal growth (weight and length), as well as the potential role of vitamin D status in explaining ethnic disparities in these outcomes. Data were derived from a large multi-ethnic cohort in The Netherlands (Amsterdam Born Children and their Development (ABCD) cohort), and included 3730 women with live-born singleton term deliveries. Maternal serum vitamin D was measured during early pregnancy (median 13 weeks, interquartile range: 12–14), and was labelled ‘deficient’ ( ≤ 29·9 nmol/l), ‘insufficient’ (30–49·9 nmol/l) or ‘adequate’ ( ≥ 50 nmol/l). Six ethnic groups were distinguished: Dutch, Surinamese, Turkish, Moroccan, other non-Western and other Western. Associations with neonatal outcomes were analysed using multivariate regression analyses. Results showed that compared with women with adequate vitamin D levels, women with deficient vitamin D levels had infants with lower birth weights ( − 114·4 g, 95 % CI − 151·2, − 77·6) and a higher risk of SGA (OR 2·4, 95 % CI 1·9, 3·2). Neonates born to mothers with a deficient vitamin D status showed accelerated growth in weight and length during the first year of life. Although a deficient vitamin D status influenced birth weight, SGA risk and neonatal growth, it played a limited role in explaining ethnic differences. Although vitamin D supplementation might be beneficial to those at risk of a deficient vitamin D status, more research is needed before a nationwide policy on the subject can be justified.

Objective: To investigate whether serum vitamin D levels have an effect on pseudoexfoliation (PEX) glaucoma/syndrome development and on the control of glaucoma in these cases. </P><P> Method: A total of 31 cases with PEX glaucoma, 34 cases with the PEX syndrome and 43 control subjects of similar age and sex were included in the study. Vitamin D levels were compared between the groups and also between the cases where glaucoma surgery was performed or not. Results: PEX glaucoma group consisted of 17 males and 14 females, PEX syndrome group of 27 males and 7 females, and the control group of 27 males and 16 females. The mean age was 70.9±8.9 years, 72.1±7.3 years, and 67.9±9.1 years in PEX glaucoma, syndrome and control group, respectively. Mean vitamin D levels were 9.4±7.7 ng/mL, 7.9±6,1 ng/mL, 11.5±14.2 ng/mL in PEX glaucoma, syndrome and control group, respectively (p>0.05). The mean serum vitamin D level was 8.04±4.7 ng/mL in those who underwent glaucoma surgery and 10.1±8.7 ng/mL in those who didn't undergo glaucoma surgery in PEX glaucoma group (p>0.05). No difference was found between the PEX glaucoma subgroups in terms of the mean deviation when classified according to vitamin D levels (<10 ng/mL, ≥10 ng/mL) (p>0.05). Conclusion: Although we found no statistically significant difference between the PEX syndrome/ glaucoma, and control group in terms of serum vitamin D levels, serum vitamin D levels were lower in PEX syndrome and glaucoma group than control group. Our results indicate that serum vitamin D levels have no effect on the development of PEX glaucoma/syndrome or the control of the disorder in cases with PEX glaucoma. However, these results need to be supported with further studies on a larger number of patients and with longer follow-up.

Abstract Background: Depression is one of the most prevalent psychiatric disorders reported in obese population. Amongst the contributing factors of depression, vitamin D deficiency has increasingly drawn attention in recent years. This paper seeks to examine the association between serum vitamin D level and depression in patients with obesity.Methods: This case-control study included 173 depressed obese patients and 174 non-depressed controls. Structured Clinical Interview for DSM-5 (SCID-5) was used to confirm the diagnosis of depression. 25-Hydroxyvitamin D [25(OH)D], Thyroid stimulating hormone (TSH), fasting blood sugar (FBS), parathyroid hormone (PTH) levels, and BMI were assessed in both groups. The statistical analyses included T-test, Chi-squared test, and multivariable logistic regression.Results: The mean 25(OH)D levels were significantly different between the case and control groups (20.43 ± 15.37 vs. 26.55 ± 13.17, P < .001). Vitamin D insufficiency/deficiency was detected in 77.6% and 67.4% of the case and control groups, respectively, which was significantly different (P = .034). Being female, greater age and lower vitamin D levels were associated with greater odds of developing depression (OR = 3.57, 95% CI = 1.82-7.02; OR = 1.05, 95% CI = 1.02-1.07; OR = 1.51, 95%CI = 1.16-1.96, respectively).Conclusion: The present study provides additional evidence with respect to the hypothesis that low vitamin D serum concentration is associated with depression in obese adults, and highlights the need for further research to determine whether this association is causal.

Background: Neonatal sepsis is one of the most important causes of an infant’s death, and the identification of its factors has been the subject of many studies. Some new evidence suggested the role of vitamin D in the occurrence of sepsis in infants. Objectives: The aim of this study was to compare the serum levels of vitamin D in neonates with sepsis in the first week of birth and healthy neonates. Methods: This case-control study was performed on 72 term neonates (36 neonates with sepsis as the case and 36 healthy neonates as the control group) who referred to Bandar Abbas children's hospitals, Bandar Abbas, Iran, from 2016 - 2017. Results: Serum vitamin D levels were measured in all infants and their mothers in both sepsis and control groups. In addition, data were collected, including sex, birth weight, C-reactive protein (CRP), and duration of hospitalization in neonates with sepsis. The mean serum level of vitamin D was 18.52 ± 11.49 ng/mL in sepsis and 20.52 ± 13.75 ng/mL in neonates of the control group (P ≥ 0.05). The mean maternal serum level of vitamin D in sepsis control groups was 22.44 ± 11.26 and 24.36 ± 12.82 ng/mL, respectively (P ≥ 0.05). There was a positive correlation between maternal and neonatal vitamin D levels in the sepsis (r = 0.803) and the control (r = 0.756) groups. However, there was no significant difference between vitamin D level and CRP (P = 0.148) and length of hospital stay (P = 0.396) in the sepsis group. Conclusions: Although the results of the present study showed a correlation between serum vitamin D levels in mothers and neonates with neonatal sepsis, there was no significant correlation between neonates with and without sepsis regarding vitamin D levels.
