Abstract Objective To assess maternal serum levels of vitamin D in fetuses appropriate for gestational age (AGA), small for gestational age (SGA), and with fetal growth restriction (FGR) according to estimated fetal weight (EFW). Methods This cross-sectional study included 87 pregnant women between 26 and 36 weeks of gestation: 38 in the AGA group, 24 in the SGA group, and 25 in the FGR group. Maternal serum vitamin D levels were assessed using the chemiluminescence method. The Fisher exact test was used to compare the results between the groups. Results The mean ± standard deviation (SD) of maternal age (years) and body mass index (kg/m2) in the AGA, SGA, and FGR groups were 25.26 ± 8.40 / 26.57 ± 4.37; 25.04 ± 8.44 / 26.09 ± 3.94; and 25.48 ± 7.52 / 26.24 ± 4.66, respectively (p > 0.05). The maternal serum vitamin D levels (mean ± SD) of the AGA, SGA, and FGR groups were 22.47 ± 8.35 ng/mL, 24.80 ± 10.76 ng/mL, and 23.61 ± 9.98 ng/mL, respectively, but without significant differences between the groups (p = 0.672). Conclusion Maternal serum vitamin D levels did not present significant differences among pregnant women with AGA, SGA, or FGR fetuses between 26 and 36 weeks of gestation according to EFW.

Objectives: To determine the association between low maternal serum vitamin D and gestational diabetes mellitus (GDM) among Filipino women in St. Luke’s Medical Center – Quezon City. Methodology: A cross-sectional study involving pregnant women at outpatient clinics in a tertiary hospital in the Philippines. Simultaneous testing for fasting blood sugar, 75g oral glucose tolerance test and serum vitamin D was done. Participants were classified as GDM versus non-GDM, and normal versus low serum vitamin D. Univariate and multivariate statistics were done to determine relationship between vitamin D and GDM. Results: Of 211 included women, 198 (93.8%) had low vitamin D levels, and 56 (26.5%) had GDM. Vitamin D was significantly higher in the GDM group (21.0±8.1 vs 18.8±5.3 ng/mL, p=0.0189). The proportion of women with low vitamin D levels was significantly higher among those without GDM (96.1% vs 87.5%, OR=0.28, p=0.029]. After adjusting for age, parity, history of GDM and pre-pregnancy BMI, no significant association was observed (adjusted OR=0.66, p=0.522). No correlation was seen between vitamin D and FBS (r=0.28, p=0.095), 1-hour post-75 g OGTT (r=0.26, p=0.643), and 2-hour post-75 g OGTT (r=0.28, p=0.113). Conclusion: There was an association found between maternal serum vitamin D level and GDM in the univariate analysis, but none was evident after adjusting for possible confounders. The unanticipated high prevalence of low vitamin D levels among pregnant Filipinos needs to be verified in future studies.

Thyroid hormones have a catabolic effect on bone homeostasis. Hence, this study aimed to evaluate serum vitamin D, calcium, and phosphate and bone marker levels and bone mineral density (BMD) among patients with different thyroid diseases. This cross-sectional study included patients with underlying thyroid diseases (n = 64, hyperthyroid; n = 53 euthyroid; n = 18, hypothyroid) and healthy controls (n = 64). BMD was assessed using z-score and left hip and lumbar bone density (g/cm2). The results showed that the mean serum vitamin D Levels of all groups was low (<50 nmol/L). Thyroid patients had higher serum vitamin D levels than healthy controls. All groups had normal serum calcium and phosphate levels. The carboxy terminal collagen crosslink and procollagen type I N-terminal propeptide levels were high in hyperthyroid patients and low in hypothyroid patients. The z-score for hip and spine did not significantly differ between thyroid patients and control groups. The hip bone density was remarkably low in the hyperthyroid group. In conclusion, this study showed no correlation between serum 25(OH)D levels and thyroid diseases. The bone markers showed a difference between thyroid groups with no significant difference in BMD.

BACKGROUND Global prevalence of paediatric asthma has shown a sharp increase in last three decades. Recently vitamin D has been linked with lung function and vitamin D supplementation can lessen the acute exacerbations in asthmatic children. The purpose of the study was to compare lung parameters and vitamin D levels in asthmatic and non-asthmatic children and assess the correlation between vitamin D levels and pulmonary function parameters in children. METHODS A cross-sectional study was conducted among 40 asthmatic children and 42 healthy volunteers between the age group of 5 and 18 years attending the paediatric outpatient department (OPD) in a tertiary care centre in Coimbatore. Pulmonary functions were assessed using computerized spirometer and the serum 25-hydroxy vitamin D levels were estimated by Diazyme EZ vitamin D assay latex enhanced immunoturbidimetric method. The results were compared between asthmatics and non-asthmatics to find out the association. RESULTS The average age of the study participants was 10.5 ± 2.5 years. Lung parameters and mean vitamin D levels are reduced in asthmatics. There is a positive significant correlation between serum vitamin D levels and forced expiratory volume FEV1 / forced vital capacity (FVC) (P < 0.05, r = 0.781), and also between vitamin D and FEV1 (P < 0.05, r = 0.28). Lung parameters like FEV1, FEV1 / FVC ratio and peak expiratory flow rate (PEFR) are significantly decreased in asthmatic children. CONCLUSIONS Majority of the asthmatics have insufficient vitamin D levels than the normal peers with no asthma. Our study confirms the positive association between vitamin D and FEV1 and FEV1 / FVC ratio. KEYWORDS Vitamin D, Asthma, Pulmonary Function, Lung Parameters

Abstract Background: Low serum vitamin D concentrations have been reported to be associated with an increased risk of non-alcoholic fatty liver disease (NAFLD). However, whether slim or obese people show a similar association between vitamin D and NAFLD remains speculative. This study aimed to explore the relationship between serum vitamin D concentrations and NAFLD in lean and obese Chinese adults.Methods: This cross-sectional study included 2538 participants (1360 men and 1178 women) who underwent their health checkups at the First Affiliated Hospital of Zhejiang University School of Medicine in 2019. NAFLD was diagnosed by liver ultrasound excluding other causes. The association of serum vitamin D concentrations with NAFLD was analyzed in lean and obese participants.Results: The overall prevalence of NAFLD was 33.61% (13.10% in lean and 53.32% in obese) in this study population. The serum vitamin D levels of obese NAFLD patients were lower than that of the obese NAFLD-free controls. However, the serum vitamin D levels of lean NAFLD patients were comparable to that of the lean NAFLD-free controls. Serum vitamin D levels were negatively correlated with the prevalence of NAFLD in obese but not lean participants. Serum vitamin D levels were independently associated with the risk of NAFLD in obese participants, with an adjusted odd ratio (95% CI) of 0.986 (0.979–0.992). However, the serum vitamin D levels were not related to the risk of NAFLD in lean participants.Conclusions: Low serum vitamin D levels are associated with NAFLD in obese but not lean participants.

Abstract Background Vitamin D deficiency is common among post-menopausal women and it is important to treat vitamin D deficiency to prevent falls and fractures in patients with osteoporosis. Few studies examined the prevalence of vitamin D deficiency in general population of Sri Lanka but no studies to date done among post-menopausal women with osteoporosis. This is the first study of such kind conducted to evaluate the serum vitamin D levels and factors related to Vitamin D deficiency among postmenopausal women.Methodology Hospital based Cross -sectional study was conducted at the Endocrine Unit, Teaching Hospital from January to December 2018.During the study period 105 postmenopausal women registered for DEXA scan with Endocrine Unit were recruited to the study. Data collection was done by investigators and blood sample was taken from each participant by registered nursing officers and sample was analysed by using immunohistochemistry assays. Serum Vitamin D levels were categorized and data analysis was done using SPSS 26.Results Mean age of 105 postmenopausal women was 67.7 with minimum 33 and maximum 84 years. Mean Vitamin D levels were 27.5(range11.7-52.5ng/ml). Vitamin D levels were adequate in only 36.2% (95%CI: 27.4-45.7) of women, 44% had insufficient levels and deficiency was present in 19% (95%CI: 12.4-27.4) of participants. Among the 105 women 20% were vegetarian and 53% of them consuming milk on average 3 days per week, 76.2% consuming fish on average 2 days per week, 64.8% consuming egg on average 1 day per week. Furthermore seventy five participants (71.4%) reported adequate level of sun exposure (>30minutes).Commonly reported vitamin deficiency symptoms includes paraesthesia (57.1%),bone pain (55.2%), easy fatigability (54.3%), malaise (51.4%), muscle cramps (43.8%) and proximal myopathy (40.0%).Among 71(66.7%) completed bone density assessment,38% (27.3-49.7) of them showed osteoporosis range. Vertebral Z score showed a significant correlation with vitamin D level(r-0.252, P-0.034).Conclusion Prevalence of vitamin D deficiency is relatively high among the post-menopausal women with a provisional diagnosis of osteoporosis. It is essential to correct vitamin D deficiency with supplementation when initiating treatment for osteoporosis. So vitamin D testing is desirable in decision making to treat or not to treat.

Objectives: To determine the relation between serum vitamin D levels and alopecia areata. Materials and Methods: This cross-sectional study included patients with AA who were above 12 years of age and age- and sex-matched controls who attended the dermatology department of a tertiary care center during a period of 1 year. Serum Vitamin D level was determined in each participant. Serum Vitamin D levels documented in both groups were compared. Results: Thirty patients and 30 age- and sex-matched controls constituted the study population. The male-to-female ratio was 1.7:1. Most of the patients (9/30, 30%) were in the age group of 31–40 years. We observed patchy AA in 17 patients (56.7%). Nail involvement was seen in 9 patients (30%). Serum vitamin D levels were insufficient/deficient in 16 patients (53.3%), while in the age- and sex-matched comparison group, vitamin D was insufficient / deficient in 7 cases (23.3%). The difference was statistically significant (P = 0.03). No significant relation was noted either between serum vitamin D levels and number of alopecia lesions or between serum vitamin D levels and the clinical pattern of AA. No significant difference was noted in the vitamin D levels between patients who had involvement of only scalp and those who showed involvement of other body sites. Limitations: Small sample size was the major limitation of the study. Conclusion: Low serum vitamin D levels were more frequent in patients with AA in comparison to healthy controls.
