Vitamin D Levels

Background: This study was done to evaluate the association of serum vitamin D level with GDM (n=30) and without GDM (n=30). The age and body mass index of the participants along with their gestational age, gravidity and parity were harmonized. The serum vitamin D levels and blood glucose were investigated. The results revealed that, normal pregnant women had significantly higher vitamin D level than their GDM counterparts.Methods: This case-control study was conducted on healthy pregnant women attending routine antenatal care at Bangabandhu Sheikh Mujib medical university from January 2019 to December 2019 recruited at third trimester of gestation. We measured maternal serum vitamin D status (25[OH]D) in third trimester of pregnancy. GDM was diagnosed according to the American diabetes association. guidelines. Vitamin D status was defined as, vitamin D sufficiency (≥30 or ≥75 nmol/L), insufficiency (20-30 and 50-75 nmol/L), were used to categories participants according to their 25[OH]D concentrations. We calculated adjusted odds ratios and 95% confidence intervals (CIs) using logistic regression.Results: The mean serum vitamin D level was lower in case group case 23.4 (17.4±35.1) compared to that in control group 29.7 (15.4±39.8) and the difference between the 2 groups was statistically significant (p≤0.001). Sufficient level of vitamin D was more in control group (66.7%) than that of case group (26.1%). Insufficient level of vitamin D was higher in case (73.3%) group than that of control (33.3%) group. These findings were significant (p=0.021). Respondents with insufficient level of vitamin D have 3.1 times more chance to develop GDM.Conclusions: Serum vitamin D level is reduced in pregnant women having GDM.

Aim of study. To study the total level of 25-hydroxyvitamin D in children with SARS-CoV-2 infection (COVID-19). Material and мethods. A total of 82 children aged 0-17 diagnosed with SARS-CoV-2 infection were enrolled. Depending on the severity of clinical symptoms, all children were divided into three groups according to the COVID-19 severity: asymptomatic, mild and moderate. The serum level of vitamin D in all patients was tested via the immunochemical method. Results. It was found that children with SARS-CoV-2 infection had lower serum level of vitamin D (29.92 [22.22; 28.07] ng/ml) as compared with the control group (36.43 [32.05; 44.08] ng/ml; p<0.001). A total of 90% of the children with SARS-CoV-2 infection were diagnosed with insufficiency or deficiency of vitamin D (<30 ng/ml). Only 10 % of the patients had normal levels of vitamin D. The insufficiency of vitamin D was found more often amongst children aged 0-11 and deficiency of total 25-hydroxyvitamin D was more common for children aged 12-17. The difference in serum levels of vitamin D depending on the severity of SARS-CoV-2 infection was not found. Male children with SARS-CoV-2 infection showed lower levels of vitamin D (p=0.013). Conclusion. A total of 90 % of the children with SARS-CoV-2 infection had insufficiency or deficiency of vitamin D regardless of the severity of clinical symptoms.

Background: Pregnancy loss in the first trimester is one of the most disappointing matters for a mother. But spontaneous pregnancy loss in the first trimester is the most common negative outcome of pregnancy. It's estimated that about 10% of known pregnancies are lost in the first trimester whereas fewer than 4% of pregnancies miscarry in the second trimester. Aim of current study was to assess the effect of the maternal vitamin D level on the risk of spontaneous pregnancy loss in the first trimester.Methods: It was a case-control study conducted in the department of obstetrics and gynecology, Sir Salimullah medical college Mitford hospital, Dhaka, Bangladesh during the period of September 2018 to August 2019. A total of 100 patients were included in this study. Statistical analyses of the results were obtained by using window-based computer software devised with SPSS version 22.0.Results: In analyzing the association of serum vitamin D status with first-trimester pregnancy state it was observed that more than half (52.0%) patients had severe deficiency (<10 ng/ml) in the case group and 14 (28.0%) patients in the control group. In total 24 (48.0%) patients had deficiency (10-20 ng/ml) in case and 35 (70.0%) in control group. Only 1 (2.0%) patient had insufficiency (21-29 ng/ml) in control group. The difference was statistically significant (p<0.05) between the two groups.Conclusions: Maternal serum vitamin D deficiency was significantly associated with early spontaneous pregnancy loss in the first trimester.

Background: Alopecia areata is the commonest cause of non-scarring alopecia. Few previous studies have found correlation between AA and vitamin D deficiency, suggesting that vitamin D deficiency can be a risk factor for Alopecia areata. To compare serum vitamin D level between Alopecia areata patients and healthy controls; and to assess the relation between serum vitamin D levels and AA disease severity.Methods: This case control study included 30 newly diagnosed Alopecia areata patients. Thorough history was taken, detail examination was done and relevant findings were recorded in the standardized pro-forma. Their serum vitamin D (25-hydroxyvitamin D) levels were determined by competitive chemiluminescence methods; and were compared with that of age and sex matched healthy controls. Chi square test and Spearman’s rho correlation test were used for the inferential statistics using SPSS version 11.5. Results: There were 30 AA patients with mean age 28.37+10.07 years. Mean Severity of Alopecia Tool score was 3.56+3.50. Prevalence of 25-hydroxyvitamin D [25(OH)D] deficiency was significantly higher in AA group (83.3%) compared to the control group (53.3%) (P=0.01). Similarly, serum 25(OH)D level was reduced more in Alopecia areata group (12.84, IQR=8.87-20.47) than the control group (29.5, IQR=19.85-41.27) (P=0.06). There was inverse co-relation between serum 25(OH)D level and SALT score.Conclusions: Prevalence of serum 25(OH)D deficiency was significantly higher in Alopecia areata group compared to the control, with inverse co-relation between its level and Alopecia areata disease severity.

Abstract Background The pathologic basis of childhood community-acquired pneumonia (CAP) involves the generation of reactive oxygen species by immune cells leading to cellular damage and lung congestion. Serum antioxidants and vitamin D with immunomodulatory properties therefore hold prospects in the prevention and management of pneumonia in children. This case–control study set out to compare the serum 25-hydroxyvitamin D (25-OHD) and total antioxidant capacity (TAC) in Nigerian children with CAP and age- and sex-matched controls and to relate these parameters with pneumonia severity and outcome—length of hospital stay (LOH). Results A total of 160 children (80 each for CAP and controls) were recruited. The median (IQR) age was 1.8 (0.6–4.0) years, male:female 1.7:1, 63 (78.8%) and 11 (13.8%) of CAP group had severe pneumonia and parapneumonic effusions, respectively. Serum 25-OHD (33.8 (18.3) ng/ml vs. 41.9 (12.3) ng/ml; p = 0.010) and TAC (6.1 (4.4–8.1) ng/dl vs. 7.2 (4.7–17.5) ng/dl; p = 0.023) were lower in children with CAP than controls. Lower serum 25-OHD was observed in severe than non-severe pneumonia (30.5(17.1) ng/ml vs. 46.3 (17.6) ng/ml; p = 0.001) but LOH did not correlate with serum 25-OHD and TAC. Conclusion Children with CAP had lower serum vitamin D and antioxidants than controls, and severe pneumonia was significantly associated with suboptimal serum vitamin D. They however were not related to pneumonia outcome. Optimal serum vitamin D and antioxidants may play a role in reducing the incidence of childhood CAP in Nigerian children.

Purpose Purpose of this study is to measure the Vitamin D status of healthy adults and to correlate with their lifestyle and feeding habits. Plasma 25-Hydroxyvitamin D (25(OH)D) is the most common marker of vitamin D status of an individual. Deficiency of vitamin D is defined as the serum level less than 20 ng/mL and insufficiency as 30 ng/mL which can be prevented. Design/methodology/approach Vitamin D status of healthy adults (n = 82), both male and females between the age of 18 – 50 years who were attending to the National Transport Authority, Kandy, Sri Lanka from February to March 2016, was measured and correlated with their lifestyle, feeding habits, etc. Findings The mean total serum D (25(OH)D in this study was 40.15 ± 3.74 nmol/l with the mean value of 42.8 ± 28.8 and 37.5 ± 16.6 for women and men, respectively. The serum calcium levels of both female and male were around 8 mg/dl and the serum total protein was 6.5 and 7 g/dl in women and men, respectively. The serum Vitamin D, calcium and total protein were not statistically significantly different between the sexes. In this study, 84 per cent of the total subjects were normocalcemic, and there was no significant relationship between vitamin D levels and their calcium levels. Research limitations/implications This study demonstrates that there was no statistically significant correlation between the serum vitamin D with age, serum calcium or total proteins. The majority of participants who had exposure to the sunlight more than 30 mins/day had sufficient level of vitamin D and less than 30 min/day exposure had deficiency of vitamin D. Daily intake of multivitamin influenced vitamin D status of the study group. Practical implications These findings will implicate the importance of cultural, feed and social habits for the nutritional status of an individual.and there are no reported studies on vitamin D status with reference to the variation of life style. Social implications It is very important to investigate the factors affecting to the vitamin D status of a population as such, vitamin D insufficiency or deficiency can be prevented. In Sri Lanka, the population is consisting with many ethnic groups, different ethnic groups may find some nutritional problems according to their main cultural habits. Originality/value The objectives of this study are to evaluate the Vitamin D status in a group of healthy adults between 20 and 50 years in both men and women and to find out the correlation of their vitamin D status with their lifestyle and feeding habits, etc.

Abstract Seasonal variation of benign paroxysmal positional vertigo (BPPV) occurrence has been reported in recent years. Whether the seasonality of BPPV also exists in Chinese patients and whether it correlates with serum vitamin D levels is unexplored. We retrospectively analyzed the data of 1269 new-onset idiopathic BPPV patients registered in our vertigo outpatient clinic over a six-year period. Additionally, serum 25-hydroxyvitamin D levels during this period were measured in 877 patients by chemiluminescence immunoassay. We delineated the changing trend of the monthly BPPV patient numbers and serum 25-hydroxyvitamin D levels, and the correlation between them was explored. December to next March is the top 4 months with higher BPPV patient numbers. The median BPPV patient numbers in winter group were higher than those in summer group (20 vs. 16 patients, p < 0.05). Median 25-hydroxyvitamin D levels in winter group were much lower than those in summer group (16.3 vs. 20.8 ng/ml, p < 0.001) and autumn group (16.3 vs. 19.3 ng/ml, p < 0.05). A moderate negative correlation was observed between median serum 25-hydroxyvitamin D levels and BPPV patient numbers each month. The onset of BPPV also shows a seasonal fluctuation in Chinese patients. This phenomenon may be related to serum vitamin D levels.

BACKGROUND: Serum levels of 25-hydroxyvitamin D (25(OH)D), prostaglandin E2 (PGE2), and cyclooxygenase 2 (COX2) expression differ between breast cancer stages. Since, previous studies showed mixed results, in this study, we aimed to analyze vitamin D levels related to breast cancer stages and serum levels of COX2 and PGE2 in Indonesia.METHODS: This was a cross sectional study involving 75 breast cancer patients. Subjects were divided into 3 groups, namely operable early stage (K1), locally advanced stage (K2), and advanced stage (K3). Venous blood samples were taken from each subject, then were analyzed for the 25(OH)D, COX2, and PGE2 serum levels by enzyme-linked immunosorbent assay (ELISA) method.RESULTS: There were significant differences in 25(OH)D among groups (p=0.012); between K1 and K2 (p=0.009) and between K1 and K3 (p=0.023). However, there was no significant difference in serum COX2 level (p=0.328). There were significant differences of PGE2 among groups (p=0.002); between K1 and K2 (p=0.036) and between K1 and K3 (p=0.001). Correlation test showed that there were differences between 25(OH)D serum levels and PGE2 serum level (r=0.306, p=0.008) and also between 25(OH)D serum level and breast cancer stage (r=-0.229; p=0.048).CONCLUSION: There were differences in serum Vitamin D and PGE2 levels at various stages of breast cancer. Serum 25(OH)D levels had weak correlation with breast cancer stage and PGE2 serum level. Serum vitamin D level in advanced breast cancer were lower than early stage breast cancer and indicate a poor prognosis.KEYWORDS: breast cancer, 25-hydroxyvitamin D, cyclooxygenase 2, prostaglandin E2

Abstract Background: This study was thus undertaken to study the estimation of vitamin D levels in pregnant women and their newborns in DRC and to study its association with various neonatal outcomes. Methods: Observational study done on 569 pregnant women and their newborn babies. Sample obtained from maternal serum and cord blood from the placental end during peripartum period. The data was analysed to estimate the prevalence of vitamin D levels in mothers and newborns and to identify association, if any, between maternal vitamin D levels and neonatal outcomes.Results: 464 mothers had sufficient vitamin D (VDS) levels (>30 ng/dL) and 105 had vitamin D deficiency (VDD) with mean maternal serum vitamin D level of 35.63ng/ml (SD 6.18, range 9.2-39.8). All the newborns (n=569) were vitamin D deficient (<30ng/ml). The percentage of LBW babies born to VDD mothers was 18.09%, which was very similar to the percentage of LBW babies born to VDS mothers (18.31%) (p=0.76456749). The incidence of caesarean section was 58.09% in the vitamin D deficient (VDD) group as compared to 19.61% in the sufficient (VDS) group (p<0.0005). The incidence of preterm births was 10.77% in the sufficient group (VDS) as compared to 17.14% in the vitamin D deficient (VDD) group (p=0.038). Conclusion: Our findings will help health professionals, policy makers, and the general public in Africa aware of the high prevalence of vitamin D deficiency and the associated health risks.

Purpose To evaluate the serum vitamin D levels of patients with vernal keratoconjunctivitis (VKC) Method A total of 39 VKC patients (21 males and 18 females) and 32 healthy individuals (19 males and 13 females) were enrolled in this study with the mean age of 18.38 ± 8.83 and 21.6 ± 9.43, respectively. The type and the grade of VKC were identified for each patient and serum 25-hydroxyvitamin D (25(OH)D) levels of all subjects were evaluated. Results The patients affected by VKC had statistically significant lower 25(OH)D levels (27.64 ± 8.50 ng/mL) than healthy subjects group (35.96 ± 11.34 ng/mL) ( p = 0.001). A reverse correlation was found between the serum vitamin D levels and the severity of the VKC but it was not statistically significant ( r = −0.159, p = 0.33). Besides, there were a few cases with severe and very severe VKC (2 in grade 3 and 4 in grade 4). Patients with the mixed type of the disease had lower serum vitamin D levels in comparison to tarsal and limbal forms but the difference was not statistically significant ( p = 0.38). Conclusion This study shows that the patients affected by VKC have lower vitamin D levels in comparison to healthy subjects and the screening of all patients with VKC for vitamin D levels seems rational.
