Abstract Introduction: Many studies have reported the role of vitamin D in rheumatoid arthritis (RA) which is related to several serum autoantibodies such as RF and Anti CCP. It also has been shown that vitamin D deficiency affect the DAS28 and VAS score inversely. Therefore, we aim to assess the relationship between vitamin D deficiency and RA-related autoantibodies including Anti CCP and RF levels and also evaluate the association between these parameters and the severity of disease.Methods: In this cross-sectional study, RA patients over 16 years of age were enrolled. The severity of diseases was assessed via the DAS28 scoring system. Serum levels of 25(OH) vitamin D were determined by the ELISA method, along with other rheumatoid related laboratory evaluations including Anti CCP, RF and CRPResults: A total of 100 patients with a mean age of 45.27± 14.14 were included and evaluated; of them, 75% were female and 77% lived in the city. Most of the patients (66%) had moderate DAS28 levels; however, no substantial relationship was observed between DAS28 and vitamin D levels. A significant positive relation between serum 25(OH)D level and disease duration, as well as the level of education, was observed. There was also no significant correlation between RA-related autoantibodies and inflammatory serum marker with 25(OH)D.Conclusion: Due to vitamin deficiency in the majority of cases (73%) and the relationship between serum 25(OH)D levels and the duration of disease, it can be concluded that vitamin D levels should be checked in those patients.

Abstract Background: Many studies have reported the role of vitamin D in autoimmune disease including rheumatoid arthritis (RA) which is related to several serum autoantibodies such as RF and Anti CCP. It also has been shown that vitamin D deficiency affect the DAS28 and VAS score inversely. Therefore, the aim of this study was to assess the relationship between vitamin D deficiency and RA-related autoantibodies including Anti CCP and RF levels and also evaluate the association between these parameters and the severity of rheumatoid arthritis.Methods: In this cross-sectional study, RA patients over 16 years of age who refer to the clinic and rheumatology ward were enrolled. The severity of diseases was assessed via the DAS28 scoring system. Serum levels of 25(OH) vitamin D were determined by the ELISA method, along with other rheumatoid related laboratory evaluations including Anti CCP, RF and CRPResults: A total of 100 patients with a mean age of 45.27± 14.14 were included and evaluated; of them, 75% were female and 77% lived in the city.

Vitamin D Levels

Introduction. Statin-associated muscle symptoms are common side effects of statin therapy. These symptoms include myopathy, myalgia, and rhabdomyolysis. Vitamin D has been associated with musculoskeletal health; thus, its deficiency may produce detrimental effects in this tissue. Indeed, one symptom of vitamin D deficiency is myalgia, and the normalization of low vitamin D levels can relieve it. Patients and Methods. This cross-sectional study examined 1210 statin-treated patients to assess vitamin D status. These patients were divided into two groups: 287 with statin-associated muscle symptoms (SAMS) and 923 control patients without SAMS. Results. We have found a significant association between deficient and insufficient vitamin D status and statin-associated muscle symptoms (SAMS). Vitamin D deficiency (<30 nmol/L) presents 77% (95% C.I. 71.6% to 81.7%) sensitivity and 63.4% (95% C.I. 60.2% to 66.5%) specificity in diagnosing SAMS. Odds ratio analysis showed that this association is moderate-strong both for deficient and for insufficient status. Conclusion. We found a correlation between vitamin D deficiency and SAMS. Therefore, vitamin D levels may be useful for the diagnosis and management of SAMS.

Background: Vitamin D deficiency and infertility are two important health problems in Iran. Some studies suggest that vitamin D may influence Anti-Müllerian hormone (AMH) and antral follicle count (AFC) as an ovarian reserve. Objective: The present study aimed to investigate the impact of vitamin D on AMH serum concentrations/AFC. Materials and Methods: three hundred and five infertile women referred to the IVF Unit of Yas hospital, between July and December 2017, were enrolled in this cross-sectional study. The demographic characteristics of the participants, as well as the serum levels of vitamin D, AMH, and ultrasonic examination of AFC were recorded. Results: Finally, 287 infertile women were included in the analysis with a mean age of 29.95 ± 4.73 yr (18-45 yr) and a mean Body mass indexof 25.11 ± 4.41 kg/m2. The median AMH and vitamin D levels were 3.20 and 22.82 ng/ml, respectively. Considering the cut-off level of 20 ng/ml, 58.7% were vitamin D deficient. Regression analysis showed no association between AMH and vitamin D levels (p = 0.161), even after adjusting for baseline variables (p = 0.182). A total of 120 patients had an AFC < 6 and 164 ≥ 6, which was not statistically different between the groups with normal level or deficient vitamin D (p = 0.133). Conclusion: The present cross-sectional study showed no significant association between serum levels of vitamin D and AMH or AFC in infertile women, even after adjusting for baseline variables. Key words: Anti-Müllerian hormone, Infertility, Vitamin D deficiency, Ovarian follicle.

AbstractVitamin D deficiency is prevalent all over the world, especially in tropical countries. In epileptics, antiepileptic drugs (AED) and associated comorbidities further impact vitamin D status. The aim of this study is to estimate the prevalence of 25(OH) vitamin D deficiency in epileptic children and evaluate probable risk factors. A cross-sectional study of 200 children between 1 and 18 years of age on AED was undertaken in the pediatric neurology clinic of a tertiary care center of Northern India. In all children, serum 25(OH) vitamin D levels, calcium, phosphorus, and alkaline phosphatase were estimated. The deficiency levels of vitamin D were categorized as: deficiency <20 ng/mL, insufficiency 20 to 30 ng/mL, and sufficiency >30 ng/mL. The potential risk factors for hypovitaminosis D, including type of epilepsy, AED regimen (specific medications, polytherapy vs. monotherapy), cerebral palsy, ambulatory status, intellectual disability, body mass index, gender, and vegetarianism were examined. Among the 200 enrolled children (60% boys), 106/200 (53%) were vitamin D deficient. There was no significant relation of vitamin D levels with gender, type of epilepsy, neurological deficit, and type of AED. An inverse relationship of higher phenytoin doses during monotherapy associated with lower vitamin D levels in monotherapy was found, thereby suggesting adverse effect of high doses of phenytoin on vitamin D levels. VDD is common among epileptic children on AED therapy. Vitamin D deficiency is common prevalent among epileptic children on AED therapy, and its detection and treatment correction should be an integral part of epilepsy management.

Objectives To assess serum 25-hydroxycholecalciferol (25-OH vitamin D) levels in Jordanian children with bronchial asthma, and to examine correlations between 25-OH vitamin D levels and asthma severity and control. Methods A cross-sectional study was conducted at the Paediatric Chest Clinic, Al-Karak Governmental Hospital, Southern Jordan, between May 2015 and February 2016. Serum 25-hydroxyvitamin D level was determined in children aged 1–14 years diagnosed with bronchial asthma (6–14 years) or recurrent wheezing episodes (<6 years). Asthma severity was determined based on the Global Initiative for Asthma assessment, the Asthma Control Test, and the Childhood Asthma Control Test. Demographic and clinical characteristics were compared between patients with low and normal 25-OH vitamin D levels, and correlations between asthma severity and 25-OH vitamin D level were assessed. Results Out of 98 included children, 25-OH vitamin D levels were deficient and insufficient in 41 (41.8%) and 34 (34.7%) children, respectively. Only 23 (23.5%) had sufficient 25-OH vitamin D levels. A significant correlation was found between severity of asthma symptoms and 25-OH vitamin D deficiency. Conclusion 25-OH vitamin D deficiency is highly prevalent in Jordanian children with bronchial asthma and correlates significantly with asthma severity.

Abstract BackgroundCoronavirus disease 2019 (COVID-19) is a pandemic disease. Experiments with influenza and severe acute respiratory syndrome (SARS) have shown supplemental vitamin D can reduce the risk of infection and death.AimThis study was performed to evaluate the relationship between vitamin D levels and the severity and outcome of admitted patients with COVID-19.Material and MethodsThis cross-sectional study was performed on COVID-19 cases diagnosed by examining RT-PCR assay for SARS-CoV-2 or a set of symptoms and typical findings in lung CT scan. Based on clinical and radiologic characteristics, the patients were categorized as mild, moderate, severe, and critical. Calcium, phosphorus, albumin, creatinine, and serum 25 hydroxy vitamin D were measured and their correlation with the severity and outcome were analyzed.ResultsFrom May 1 to June 31, 2020, 508 patients ((442 patients in general wards and 66 patients in intensive care unit (ICU)) were included in this study. The participants were 56±17 years old (mean ±SD) (range from 14 to 95 years) and 52% were male. According to the past medical history, 190 (37.4%) of them had comorbidity. Concerning severity, 13.2%, 42.3%, 35.4%, and 9.1% had the mild, moderate, severe, and critical disease, respectively. The in-hospital mortality rate was 10.8%. In the multivariate regression analysis, age had a positive correlation and use of vitamin D supplement, serum level of 25 OH vitamin D, calcium, and albumin had a negative correlation with disease severity and admission to ICU. Poor outcome was inversely related to serum levels of vitamin D, calcium, albumin, and renal function. Vitamin D deficiency increased the rate of ICU admission by 2.7 times (95%CI=1.288-5.91, P=0.009).ConclusionIn patients who are hospitalized due to COVID-19, low 25-hydroxyvitamin D, hypocalcemia, and hypoalbuminemia are associated with severe disease, ICU admission, and an increase in mortality.

Objective: Investigate the prevalence of vitamin D deficiency in an equatorial population through a large-sample study. Methods: Cross-sectional study with 30,224 healthy individuals from the North Region, in Brazil (Amazônia – state of Pará), who had 25-hydroxy-vitamin D (25(OH)D) and intact parathyroid hormone (PTH) serum levels measured by immunoassay method. Those with history of acute or chronic diseases were excluded. Abnormal levels of calcium, creatinine, glycemia and albumin were also exclusion criteria. Results: 25(OH)D levels were 29.1 ± 8.2 ng/mL and values <12.7 ng/mL were equal to < −2 s.d. below average. Hypovitaminosis D was present in 10% of subjects according to the Institute of Medicine (values <20 ng/mL) and in 59%, in consonance with Endocrine Society (values 20–30 ng/mL as insufficiency and <20 ng/mL as deficiency) criteria. Individuals were divided according to four age brackets: children, adolescents, adults and elderly, and their 25(OH)D levels were: 33 ± 9; 28.5 ± 7.4; 28.3 ± 7.7; 29.3 ± 8.5 ng/mL, respectively. All groups differed in 25(OH)D, except adolescents vs adults. Regression model showed BMI, sex, living zone (urban or rural) and age as independent variables to 25(OH)D levels. Comparing subjects with vitamin D deficiency (<20 ng/mL) to those with vitamin D insufficiency (20–30 ng/mL), a difference between PTH levels in these two groups was observed (95.9 ± 24.7 pg/mL vs 44.2 ± 64.5 pg/mL; P < 0.01). Additionally, the most accurate predictive vitamin D level for subclinical hyperparathyroidism in ROC curve was 26 ng/mL. Conclusion: Our equatorial population showed low prevalence of vitamin D hypovitaminosis ranging with age bracket. The insufficient category by Endocrine Society was corroborated by our PTH data.

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.

Background: The possibility of vitamin D deficiency is high among mothers and their premature newborns. Objectives: Due to the high rate of vitamin D deficiency in Iranian women, this study aimed to determine the association between the serum levels of vitamin D in the blood of premature newborns and their mothers in the Iranian population. Methods: This cross-sectional study was conducted on 324 mothers and their 324 newborns with gestational age less than 37 weeks, who were referred to Ghaem Hospital affiliated to Mashhad University of Medical Sciences, Mashhad, Iran, during 2016-2020. After clamping, 1.5 cc blood samples were obtained through the umbilical cord to determine the neonates’ vitamin D levels. Finally, the serum levels of vitamin D were measured, and the correlation between the levels of vitamin D of mothers and their newborns was calculated. Results: The mean vitamin D levels of newborns and mothers were 15.75 ± 11.18 and 20.16 ± 13.41 ng/mL, respectively. Moreover, there was a high correlation between the vitamin D levels of mothers and their newborns (r = 0.672; P < 0.001). Furthermore, a significant correlation was observed between the vitamin D levels of mothers, who used vitamin D supplementation during pregnancy and their neonates’ levels (r = 0.773; P < 0.001). Conclusions: The findings suggest a positive correlation between neonatal and maternal vitamin D levels. Moreover, it seems that maternal vitamin D levels can predict neonatal vitamin D deficiency.
