Monocyte-to-HDL Ratio (MHR) Predicts Vitamin D Deficiency in Healthy and Metabolic Women: A Cross-Sectional Study in 1048 Subjects

Vitamin D deficiency is often linked with Metabolic Syndrome, both being more frequent with ageing and associated with an increase inflammatory state. Recently, monocytes-to-high density lipoprotein (HDL) ratio (MHR) has emerged as a powerful index to predict systemic inflammation. In this cross-sectional study, we investigated the association between circulating vitamin D level (25-OH vitamin D) and inflammatory status in a population of 1048 adult individuals. Our study reveals an inverse association between 25-OH vitamin D levels and MHR in the overall population. When the population is stratified by gender, waist circumference, and body mass index (BMI), we observed that while in men this relation is strongly significative only in condition of central obesity, in women a lifelong negative correlation exists between circulating 25-OH vitamin D and MHR and it is independent of the metabolic status. These observations underscore the relevance of circulating biomarkers such as MHR in the prediction of systemic inflammatory conditions sustained by vitamin D deficiency also in healthy and young women.

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.

The Relationship

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 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.

Introduction: Indian population has a paradoxically high prevalence of vitamin D deficiency. Maternal vitamin D levels are related to outcomes of pregnancy for mother and foetus. To understand the need for screening and appropriate management decisions, data is needed from various regions of India to explore the magnitude of the problem. Aim: To evaluate the vitamin D levels in pregnant mothers and their newborns at a hospital catering to the affluent population in Mumbai. Materials and Methods: A cross-sectional study was conducted from August to December 2012. A 100 women of Indian origin, between 20-45 years of age and their newborns who were delivered at the Lilavati Hospital and Research Centre in Mumbai were included. Determination of 25 hydroxy (OH) vitamin D, serum calcium, albumin concentration was done in mothers just before delivery and newborns venous cord blood at the time of delivery. Pearson’s correlation test was used for determining relation between maternal and newborns vitamin D levels and Chi-square test for association of maternal vitamin D levels with their sun exposure and newborns birth weight. Results: The distribution of serum 25 (OH) vitamin D status in mothers was 75 deficient (75%), 13 insufficient (13%) and 12 sufficient (12%). Mean serum 25 (OH) vitamin D in mothers was 15.09 ng/mL. The distribution of serum 25 (OH) vitamin D levels in newborns were 78 deficient (78%), 13 insufficient (13%) and 9 sufficient (9%). Mean serum 25 (OH) vitamin D in neonates was 13.82 ng/mL. There was strong correlation between maternal and newborns serum 25 (OH) vitamin D levels with a Pearson correlation coefficient value of 0.94 and the p-value of <0.001. Conclusion: There was a high prevalence of vitamin D deficiency in pregnant mothers associated with hypovitaminosis D in newborns in this hospital-based study catering to affluent population from Mumbai.

Introduction: Vitamin D deficiency increases inflammation and dysfunction of pancreas betacells, resulting in atherosclerotic disorders, cerebrovascular disorder, and CVDs. Methods: In the present cross-sectional study, vitamin D was evaluated in the plasma of 42 patients with lower extremity DVT or PE, as well as 42 healthy controls. Using the chemiluminescence assay, the plasma vitamin D levels were determined. After collection, the blood samples were examined within 60 minutes. Vitamin D levels were classified as sufficient, insufficient, and deficient (> 30 ng/mL, 20- 29 ng/mL, and < 20 ng/mL, respectively). Results: The prevalence of deficiency in vitamin D was higher in the cases than the controls. The two groups were significantly different regarding vitamin D levels (p = 0.024). Based on the vitamin D classification, deficiency was reported in 30 (71.4%) patients and 18 (42.9%) controls. Conclusion: Our findings indicated that VTE patients had lower concentration of vitamin D, and the correlation between VTE and vitamin D deficiency was confirmed.

Abstract Background : Asthma is the most common chronic diseases that affect children and its prevalence is increasing worldwide posing a great burden on healthcare systems. A growing body of evidence suggests an association between vitamin D deficiency and asthma. The current study aimed to assess serum vitamin D level in Jordanian children with bronchial asthma and to examine the correlation between vitamin D levels and asthma severity and control. Methods: A cross sectional study was conducted in the Pediatric Chest Clinic at AlKarak Governmental Hospital South of Jordan from May 2015 to February 2016. Serum level of 25-hydroxyvitamin-D was determined for 98 Children aged 1 to 14 years and diagnosed with bronchial asthma (6-14years) or recurrent wheezing episodes(<6 years). The severity of asthma was determined based on the Global Initiative for Asthma (GINA) assessment, the Asthma Control test (ACT) and the Childhood Asthma Control Test (C-ACT). The results were considered significant if P ≤.05. Statistical analysis was performed using SPSS 21 (IBM, Armonk, NY, United States of America, 2012). Results : Vitamin D levels were deficient and insufficient in 41(41.8%) and 34(34.7%) of asthmatic children, respectively. Only 23( 23.5%) had sufficient vitamin D levels. A significant correlation was found between the severity of asthma symptoms and vitamin D deficiency (Pearson Chi-squared=.028). Conclusion : Vitamin D deficiency is highly prevalent in children with bronchial asthma in Jordanian population and correlates significantly with asthma severity. Assessment of vitamin D levels in children with bronchial asthma is required in a larger scale studies in Jordan.
