Introduction: Vitamin D, a steroid vitamin, has attracted noticeable interest of clinicians and researchers for decades because of its diverse array of biological functions. Various studies have shown that the level of vitamin D is low in significant proportion of healthy individuals. However, indoor workers especially health care professionals are not focused, particularly in Nepal. We aimed to measure level of vitamin D in apparently healthy health care professionals. Methods: A descriptive cross-sectional study was carried out in apparently healthy health care professionals working at Kathmandu University Hospital in Dhulikhel, Nepal. Structured questionnaire including socio­demographics, dietary habits, and anthropometric measurements was filled in by the participants. Total serum 25-hydroxy vitamin D was measured by Chemiluminescence Immunoassay (CLIA) technique. Results were analyzed with t-test, Chi-square test, and Pearson correlation test. Results: Data from 64 female and 47 male were analyzed, mean 25-hydroxy vitamin D level was 8.81 ng/dl (SD = 4). Almost all (98.2%, n = 109) participants had vitamin D lower than normal where 72.7% (n = 92) were deficient, 24.5% (n = 17) were insufficient, and only 2.7% (n = 2) were having adequate level. Non-specific body pain was the only factor among all we studied that was significantly associated with vitamin D levels (p = 0.002). Conclusion: Hypovitaminosis of 25-hydroxy vitamin D was found to be very common (98.2%) in apparently healthy health care subjects of Dhulikhel Hospital. This may necessitate further research to redefine the biological reference value for our population.

<b><i>Aim:</i></b> To describe the demographic characteristics, risk factors, and presenting features of children with symptomatic nutritional rickets in France. <b><i>Methods:</i></b> This is a retrospective study of 38 children diagnosed with nutritional rickets from 1998 to 2019. <b><i>Results:</i></b> We observed a higher frequency of rickets in males (74 vs. 26%), in young children (median age at diagnosis: 23 months; 82% were younger than 5 years), and in children with a non-Caucasian ethnic background (89%). Most children were exclusively breastfed (78%) without adequate vitamin D supplementation (89%). The most common presentations were bowed legs (63%), hypocalcemic seizures (21%), and growth retardation (11%). Approximately half (62%) of the children were hypocalcemic. The children presenting with hypocalcemic seizures were significantly younger (0.8 vs. 2.2 years; <i>p</i> = 0.041) and had lower total serum calcium levels (1.44 vs. 2.17 mmol/L; <i>p</i> &#x3c; 0.0001), higher phosphatemia (1.43 vs. 1.23 mmol/L; <i>p</i> = 0.020), and lower 25-hydroxy vitamin D levels (3 vs. 7 ng/mL; <i>p</i> = 0.020) but similar parathyroid hormone levels (357 vs. 289 ng/mL; <i>p</i> = 0.940) compared to rickets cases who did not experience hypocalcemic seizures. A dilated cardiomyopathy was detected in 14% of the children who had undergone echocardiography. <b><i>Conclusion:</i></b> Nutritional rickets remains endemic in the pediatric population and its most severe forms can have life-threatening sequelae. Health practitioners need to be cognizant of these facts to raise awareness and screen high-risk populations.

Background: It is well known that deficiency of 25 - hydroxy Vitamin D can cause various musculoskeletal manifestations as well as metabolic, non-musculoskeletal abnormalities. There may be a chance that hypovitaminosis D can act as a causative factor for congenital anomalies. Aims and Objectives: The present study was planned to evaluate the level of 25 - hydroxy Vitamin D in cord blood in cases of congenital anomalies and its association with cord blood fluoride levels in newborns with visible congenital anomalies. Materials and Methods: Thirty newborns with visible congenital anomalies were included in group I and thirty healthy newborns without any congenital anomalies were included group II. Ten mL cord blood was collected from the placental end of umbilical cord immediately after delivery of the baby and serum was separated. Serum 25 - hydroxy Vitamin D and fluoride were analyzed by standard methods. Statistical analysis: Results were expressed as Mean ± SD. Unpaired ‘t’ test and Pearson correlation test were applied. Data were considered to be significant if p < 0.05. Results: Serum 25 - hydroxy Vitamin D levels were significantly decreased in babies with congenital anomalies (p=0.001) and show a significant negative association with fluoride.Anomalies related to central nervous system and musculoskeletal systems had the lowest 25 - hydroxy Vitamin D levels and highest serum fluoride levels than other anomalies of other systems. Conclusion: Fluoride can acts as an inhibitor for activation of calciferol causing a decrease in 25 - hydroxy Vitamin D levels. Thus 25 - hydroxy Vitamin D is an important micronutrient for proper development of the fetus and association of it with excess fluoride can cause congenital anomalies.

This cross-sectional study enrolled 180 patients at a private family practice in Virginia. Total serum vitamin D concentrations were obtained weekly from January 30, 2013, through March 30, 2013, in consecutive patients regularly scheduled for laboratory work at the practice. Patients were categorized into 2 groups and analyzed for variant alleles in vitamin D receptor ( VDR; rs2228570), cytochrome P450 2R1 ( CYP2R1; rs10741657), 7-dehydrocholesterol reductase ( DHCR7; rs12785878), and group-specific component ( GC; rs2282679) to determine whether variants of those alleles influenced total serum 25(OH)D concentrations. One-hundred and eighty patients were enrolled, with 40 (22%) being sufficient, 25-hydroxy vitamin D level 25(OH)D ≥ 30 ng/mL, and 140 (78%) being insufficient, 25(OH)D < 30 ng/mL. Of the 4 genes, 2 genes, CYP2R1 (rs10741657) and GC (rs2282679), demonstrated a significant association related to vitamin D status. Subjects with 1 or more variant alleles at rs10741657 were almost 3.7 (odds ratio [OR] 3.67; 95% confidence interval [CI]: 1.35-9.99) times more likely be insufficient in vitamin D and subjects with 1 or more variant alleles at rs2282679 were about half (OR 0.42; 95% CI: 0.18-0.93) as likely to be insufficient in vitamin D. Allelic variations in CYP2R1 (rs10741657) and GC (rs2282679) affect vitamin D levels, but variant alleles on VDR (rs2228570) and DHCR7 (rs12785878) were not correlated with vitamin D deficiency, 25(OH)D < 30 ng/mL.

The objectives of this study were to estimate the prevalence of vitamin D deficiency in patients with acute coronary syndrome in comparison with normal individuals and study the correlation between these two conditions. We measured the plasma 25-hydroxy vitamin D (25-OH-D) levels in 60 patients with acute coronary syndromes (ACS) of both gender and in 30 age matched control individuals of both gender without any known cardiovascular or systemic diseases. The levels of 25-OH-D were measured by ELISA method and the results were statically analyzed to find out any possible correlation. We classified the cases according to their plasma 25(OH)D levels. 25(OH)D levels of ≥ 30 ng/ml were considered normal, levels < 30 and > 20 ng/ml were classified as insufficient, while levels of ≤ 20 ng/ml were classified as deficient. In the current study the prevalence of hypovitaminosis D in the patients group was much higher than it was in the control group. Vitamin D deficiency was observed in 80% and insufficiency in 13% of total patients of ACS, there by bringing the total count to 93%. Whereas only 7% of the patients had adequate vitamin D levels. Thus, these results indicate the existence of a significant correlation between the vitamin D deficiency and ACS in comparison to healthy controls

Background. Patients with liver cirrhosis experience a large variety of metabolic disorders associated with more hepatic decompensation. Hepatic encephalopathy (HE) is a significant complication in liver cirrhosis patients, presenting a wide spectrum of neuropsychological symptoms. A deficiency of 25-hydroxy vitamin D (25-OHD) in the general population is associated with a loss of cognitive function, dementia, and Alzheimer’s disease. Aim of the Study. Our study aims to check the relationship between low serum 25-OHD and HE in patients with HCV-related liver cirrhosis and assess its link with patient mortality. Patients and Methods. This study was observationally carried out on 100 patients with HCV-related liver cirrhosis. The patients were divided into 2 groups: Group A—included 50 HCV-related cirrhotic patients with HE, and Group B—included 50 HCV-related cirrhotic patients without HE. Assessment of disease severity using the end-stage liver disease (MELD) model and Child Turcotte Pugh (CTP) scores were done, and 25-OHD levels were measured. Comparison of vitamin D levels in different etiologies and different CTP categories was made using one-way ANOVA. Pearson’s correlation between the level of vitamin D and other biomarkers was applied. Results. There was a statistically significant Vitamin D level difference between the two groups. A lower level of vitamin D was observed in the HE group where the severe deficiency was 16%, while it was 6% in the other group and the moderate deficiency was 24% in HE group as compared to 10% in the other group. The insufficient vitamin D level represented 46% of the non-HE group while none of the HE group falls in this category. Vitamin D level was statistically higher in Grade 1 HE than in Grade 2 which is higher than in Grades 3 to 4. Vitamin D level was also significantly higher in those who improved from HE as compared to those who died. Conclusion. The lower levels of 25-OHD were associated with the higher incidence of HE in cirrhotic HCV patients. The worsening vitamin D deficiency was associated with increased severity of the liver disease, so vitamin D may be considered a prognostic factor for the severity of liver cirrhosis and high mortality rate in HE patients.

Abstract Background: Previous cross-sectional studies have shown that Parkinson’s disease (PD) patients have lower serum 25- hydroxy vitamin D (25(OH)D) concentrations than controls. whether the research in other regions findings are generalizable to China populations remains untested in other studies. In this case-control study we examined the Correlation between 25-hydroxy-vitamin D and Parkinson's disease.Methods:We establish an association between deficiency of 25-hydroxy-vitamin D and PD in a case-control study of 100 PD patients and 100 control subjects free of neurologic disease in the First Affliated Hospital of Xinjiang Medical University.Results:Total 25-hydroxy-vitamin D levels, were deficient in 21% of patients with PD compared with 4% of controls. In univariate analyses Plasma levels of 25-hydroxy-vitamin D were associated with PD(p<0.001), respectively. In multivariate analyses, Vitamin D deficiency(25(OH)D <20 ng/mL) were significant associated with PD (p=0.008,OR=17.13,95% CI, 2.082-141.075). Individuals with levels in the lowest quartile of 25(OH)D values had the highest prevalence of PD(p =0.026,OR=11.786,95%CI,1.342-103.51)compared with individuals with values in the highest quartile.Conclusions:Our study reveals an association between 25-hydroxy-vitamin D and PD.Patients with incident PD had significantly lower serum 25(OH)D concentrations than age-matched controls, High-risk PD patients with vitamin D deficiency who have not yet developed exercise impairment, these populations should undergo vitamin D measurement and vitamin D treatment as soon as possible.

Abstract Serum total 25-OHD is a main marker of vitamin D which represents the intake and sunlight exposure. Free form of 25‐OHD, the small fraction not bound to a transporter protein has been incorporated as a new marker. This cross-sectional study aimed to evaluate the impact of several factors on total and free vitamin D levels in healthy subjects and to find out if the free form of vitamin D could be a better representative of the body’s vitamin D status. Total and free 25‐OHD were analyzed by ELISA method in a blood sample collected from 391 apparently healthy volunteers (219 female and 172 Male) from Duhok Governorate/Iraq population. Total and free 25‐OHD levels were increased proportionally to BMI with lower values seen in the underweight group, also a significant gender differences in total D3 level with higher values in males (23.90 ± 16.41) ng/ml than females (21.24 ± 15.65) ng/ml was observed. Total and Free 25‐OHD levels were significantly associated with ages, their deficiency most frequent occurs in the younger ages between (16–25) years old. Smokers had higher level of Total 25‐OHD (26.95 ± 19.01) ng/ml and Free 25‐OHD (9.47 ± 4.94) pg/ml than nonsmokers (22.14 ± 14.59) ng/ml and (7.87 ± 4.32) pg/ml respectively. A significant increase in Free 25‐OHD level in the veiled women (9.12 ± 4.64) ng/ml than unveiled (6.16 ± 3.73) ng/ml with a significant positive correlation between Free 25‐OHD level and dress style was also seen. 30% and 33% of the participants whom their daily exposure to sunlight for 30 minutes and > 1hour respectively were severe deficient in total 25‐OHD. 95% of the participants who had Abnormally low level of free D were exposed for ≥ 30 minutes to sunlight. Daily exposure to sunlight was negatively associated with Free 25‐OHD level.
