AbstractAtopic dermatitis (AD) patients have been observed to have lower vitamin D levels. Previous studies have found little evidence that vitamin D levels causally influence the risk of AD, but the reverse direction has not yet been investigated.Here we used Mendelian Randomization to assess the causal relationship between AD and serum vitamin D levels, using genetic data from the most recent GWA studies of vitamin D and AD.There was little evidence for vitamin D levels causally influencing AD risk (odds per standard deviations increase in log-transformed vitamin D levels =1.233, 95% CI 0.927 to 1.639, P-value =0.150). However, genetic liability for AD raises serum vitamin D levels by 0.043 (95% CI 0.017 to 0.069) standard deviations per doubling of odds of disease (P-value =0.001). The AD-associated filaggrin (FLG) mutation R501X appears to show a particularly strong relationship with vitamin D. However, the relationship between AD and vitamin D holds when R501X is omitted (0.018, 95% CI 0.004 to 0.031, P-value =0.008).We found evidence that AD is causally associated with an increase in serum vitamin D levels. Whilst the AD-associated FLG gene has a particularly strong relationship with vitamin D, other AD SNPs show a consistent direction of effect, suggesting that AD more generally influences serum vitamin D levels.

Purpose Lower serum vitamin D levels have been associated with an increased risk of aggressive prostate cancer. Among men with localized prostate cancer, especially with low- or intermediate-risk disease, vitamin D may serve as an important biomarker of disease aggression. The aim of this study was to assess the relationship between adverse pathology at the time of radical prostatectomy and serum 25-hydroxyvitamin D (25-OH D) levels. Methods This cross-sectional study was carried out from 2009 to 2014, nested within a large epidemiologic study of 1,760 healthy controls and men undergoing prostate cancer screening. In total, 190 men underwent radical prostatectomy in the cohort. Adverse pathology was defined as the presence of primary Gleason 4 or any Gleason 5 disease, or extraprostatic extension. Descriptive and multivariate analyses were performed to assess the relationship between 25-OH D and adverse pathology at the time of prostatectomy. Results Eighty-seven men (45.8%) in this cohort demonstrated adverse pathology at radical prostatectomy. The median age in the cohort was 64.0 years (interquartile range, 59.0 to 67.0). On univariate analysis, men with adverse pathology at radical prostatectomy demonstrated lower median serum 25-OH D (22.7 v 27.0 ng/mL, P = .007) compared with their counterparts. On multivariate analysis, controlling for age, serum prostate specific antigen, and abnormal digital rectal examination, serum 25-OH D less than 30 ng/mL was associated with increased odds of adverse pathology (odds ratio, 2.64; 95% CI, 1.25 to 5.59; P = .01). Conclusion Insufficiency/deficiency of serum 25-OH D is associated with increased odds of adverse pathology in men with localized disease undergoing radical prostatectomy. Serum 25-OH D may serve as a useful biomarker in prostate cancer aggressiveness, which deserves continued study.

Introduction: Coronavirus disease 2019 (COVID-19) from the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is one of the most important epidemiological events in the past 100 years has become, the consequences for public health and economic systems around the world. Vitamin D is an important micronutrient that has been reported to improve immunity and protect against respiratory diseases. In this study, we intend to review articles that examine the relationship between COVID-19 and vitamin D. Methods: This is a review that uses articles from studies published in 2020 on the relationship between COVID-19 and vitamin D in databases such as; Web of Science, Science Direct, SID, Magiran, Google Scholar and PubMed. Keywords used included; serum levels of 25-hydroxyvitamin D, vitamin D, COVID-19, SARS-COV-2 and coronavirus 2. With this search, 32 articles were finally selected for this purpose and their results were reviewed Results: Of the 32 studies reviewed, only three showed no association between vitamin D levels in the blood and COVID-19 disease. Other studies had a relationship between the severity of the disease, mortality rate and length of hospital stay, in different age, gender and location groups. Conclusion: It seems that the level of vitamin D in the blood has a potential effect on COVID-19 disease. Checking the serum vitamin D levels and supplementation in people with hypovitaminosis D can be a good solution to reduce the complications and problems caused by COVID-19.

The Relationship

The review presents data from 56 publications about functions of vitamin D in the human body, the mechanisms of its action and the relationship between lung diseases and the level of vitamin D in the blood. Low serum vitamin D levels are associated with impaired lung function and an increase in inflammatory, infectious, or neoplastic diseases. The results of numerous studies allow considering vitamin D not only a marker of different courses of bronchopulmonary diseases but also as a therapeutic target in the treatment of patients with chronic obstructive pulmonary disease while maintaining the immune system and anti-infectious protection.

Background: Hypovitaminosis D, low bone mineral density, non-specific musculoskeletal pain, increased risk of fracture, and periodontal disease were reported in most subjects recruited from the Methadone Maintenance Treatment (MMT) program. This study aimed to determine the relationship between vitamin D levels and the severity of anxiety and depression in patients under MMT. Methods: In a cross-sectional study, serum vitamin D levels were measured among 500 patients under MMT from Kashan Province, Iran. Correlation tests were used to assess the association of vitamin D levels with the severity of anxiety and depression in the explored patients. Results: We found that serum vitamin D levels were positively correlated with the scores of the Beck Depression Inventory (BDI) (r=0.107, P=0.017) and the Beck Anxiety Inventory (BAI) (r=0.129, P=0.004). Additionally, there was a negative correlation between serum vitamin D levels, MMT dosage (r=-0.011, P=0.8), and the duration of MMT (r=-0.017, P=0.7). Conclusion: Our findings demonstrated that serum vitamin D levels were independently correlated with the BDI and BAI scores. Further studies are required to confirm our findings.

The Relationship

As the relationship between vitamin D and various diseases or health conditions has become known, interest in the contribution of vitamin D to overall health-related quality of life (QoL) has increased. We examined the relationship between vitamin D status and QoL in 273 participants aged 65 years and older. Serum levels of total calcium, phosphorus, intact parathyroid hormone, albumin, and 25-hydroxyvitaminD3 were analyzed. We also recruited data for QoL, physical activity, nutritional impairment, and muscular strength. Ninety percent of the subjects were classified as vitamin D deficient or insufficient. Participants with higher serum 25(OH)D3, calcium, phosphorous, and Alb levels were significantly less likely to self-report depression or anxiety after adjustment (p = 0.009, p = 0.005, p = 0.003, and p = 0.005, respectively). Additionally, we found an association between lower levels of albumin and self-reported problems with mobility or usual activities (p = 0.01). We also found associations between better muscle strength and higher levels of vitamin D, calcium, phosphorous, and albumin (p = 0.006, p = 0.003, p = 0.004 and p = 0.002, respectively). Overall, our data provide evidence that serum vitamin D and Alb levels are negatively related to self-reported anxiety or depression, usual activities, mobility, and three dimensions of QoL in older adults. Furthermore, vitamin D levels are positively related to hand grip strength in adults over 65 years old.

Background: Coronary artery disease (CAD) is one of the most common cardiovascular diseases that can lead to mortality, inability, and lower productivity levels. Objective: The aim of this study was to determine the relationship between serum vitamin D level and cardiovascular risk factors and the severity of CAD after determining and eliminating the confounding effects of dietary patterns in male patients undergoing angiography. Methods: This descriptive-analytic study was carried out on 132 men undergoing angiography during 2017 and 2018. To this end, food frequency questionnaire (FFQ) and physical activity questionnaire (PAQ) were completed for the patients. Fasting blood sugar (FBS), triglyceride, total cholesterol, HDL-C, LDL-C and vitamin D levels were also investigated. Results: Serum vitamin D levels significantly decreased with an increase in CAD severity (p=0.001). Also, low serum levels led to the highest severity of CAD (p=0.005). However, there was no significant difference between patients with vitamin D deficiency with different degrees of CAD (p=0.084). Also, the highest percentage of individuals with normal serum levels of vitamin D was observed in the group without any blocked blood arteries (normal) (p=0.023). Conclusion: This study shows an inverse relationship between serum 25(OH) D level and the severity of CAD. Our data show that vitamin D plays an important role in preventing CAD. These findings could help design prospective studies and clinical trials on a wider scale to investigate the effects of vitamin D interventions in preventing the development of CAD.
