AbstractBackgroundSARS-CoV-2 virus causes a very wide range of COVID-19 disease severity in humans: from completely asymptomatic to fatal, and the reasons behind it are often not understood. There is some data that Vitamin D may have protective effect, so authors decided to analyze European country-wide data to determine if Vitamin D levels are associated with COVID-19 population death rate.MethodsTo retrieve the Vitamin D levels data, authors analyzed the Vitamin D European population data compiled by 2019 ECTS Statement on Vitamin D Status published in the European Journal of Endocrinology. For the data set to used for analysis, only recently published data, that included general adult population of both genders ages 40-65 or wider, and must have included the prevalence of Vitamin D deficiency.ResultsThere were 10 countries data sets that fit the criteria and were analyzed. Severe Vitamin D deficiency was defined as 25(OH)D less than 25 nmol/L (10 ng/dL). Pearson correlation analysis between death rate per million from COVID-19 and prevalence of severe Vitamin D deficiency shows a strong correlation with r = 0.76, p = 0.01, indicating significant correlation. Correlation remained significant, even after adjusting for age structure of the population. Additionally, over time, correlation strengthened, and r coefficient asymptoticaly increased.ConclusionsAuthors recommend universal screening for Vitamin D deficiency, and further investigation of Vitamin D supplementation in randomized control studies, which may lead to possible treatment or prevention of COVID-19.

Objective: We aimed to find out the association of low serum vitamin D levels with the incidence of prostate cancer through a prospective case-control study. Material and methods: This study was carried out in the tertiary care hospital (India). All newly diagnosed patients of prostate cancer and age-matched controls were included. Serum vitamin D levels were measured in all of them. Vitamin D status (ng/mL) was classified as severe deficiency <10, moderate deficiency 10–<30, normal 30–100, and toxicity >100. Normality of the data was tested by the Kolmogorov–Smirnov test, statistical analysis was done with Statistical Package for the Social Sciences version 26.0, p-value of <0.05 was considered significant. Results: In our study, 320 cases and 320 controls were included. The mean vitamin D levels in cases and controls were 15.71 ± 6.5 (ng/mL) and 17.63 ± 4.54 (ng/mL), respectively, ( p-Value <0.01). Patients with severe vitamin D deficiency (73.58%) had a Gleason score ⩾8 on biopsy and 79.24% of them had a serum prostate specific antigen (PSA) level >20 ng/mL. Conclusion: We had concluded that there was no significant association between vitamin D deficiency and increased risk of prostate cancer, although patients with higher-grade prostate cancer and with higher PSA level had severe vitamin D deficiency. Level of evidence: Not applicable for this multicentre audit.

Background: Normal growth and development requires vitamin D, and its deficiency compromises long term health and increases the risk of chronic disease. Severe vitamin D deficiency include rickets, osteomalacia, osteoporosis, increased risk of fracture, tooth loss. Studies indicate that vitamin D insufficiency (less severe than deficiency) is associated with a wide range of illnesses and chronic conditions, including type 1 diabetes, hypertension, multiple sclerosis and many types of cancer. Currently world is facing an unrecognized and untreated pandemic of vitamin D deficiency. This study aims at showing the relation between Vitamin D status and obesity in adolescent children and to know the dietary factors, life style factors like physical activity contributing to overweight and obesity in adolescents.Methods: Study design: This is an observational study of 30 overweight and obese adolescents based on BMI were studied and their Vitamin D levels were assessed.Results: A total of 14(46.7%) overweight and 16(53.3%) obese adolescents Vitamin D levels were assessed. 20(66.7%) had vitamin D levels <20ng/ml that is in the deficiency range.4(13.3%) had in the insufficiency range (21-30ng/ml), 6(20%) had in the sufficient range. Results shows vitamin D levels were significantly less in obese and overweight adolescents.Conclusions: Study results confirm that Vitamin D deficiency or insufficiency is common to obese and overweight adolescents, this may help to explain the relationship between obesity and several chronic diseases that are associated with poor Vitamin D status.

Background: Laryngopharyngeal Reflux (LPR) is a condition in which gastric content reflux into the larynx and pharynx. It is one of the extraesophageal manifestations of gastroesophageal reflux disease (GERD), involving the laryngeal regio. The laryngopharyngeal epithelium is more susceptible to reflux-related tissue injury than the esophageal epithelium. Objectives: This study aimed to test the hypothesis of whether severe vitamin D deficiency results in increased Laryngopharyngeal reflux (LPR) symptoms in Indian females. The objective was to find out the prevalence of LPR in the severe vitamin D deficient Indian female population. Methods: A descriptive observational study was done at a multispecialty polyclinic in New Delhi, India, over a period of one year. Based on a pilot study, a sample size of 185 individuals was taken. All females referring to the general outpatient department (OPD) with vitamin D levels below 20 ng/ml were included. The frequency of LPR symptoms in the study participants was assessed using the reflux symptom index (RSI) and reflux finding score (RFS) given for all symptomatic patients using a validated scoring system. The data were analyzed descriptively with Microsoft Excel and SPSS version 21 using appropriate tests. Results: In this study, 92% of the subjects aged more than 25 years, and the mean vitamin D level was 9.87 (± 3.425) ng/ml. Moreover, 74% of study participants had severe vitamin D deficiency (≤ 10 ng/ml). The mean RSI for our study participants was 14.54 (± 10.353). Also, the mean RFS was 1.77 (± 3.069). No significant correlation was established between the severity of vitamin D deficiency and RSI as well as RFS. The prevalence of LPR was 43%. Conclusions: Hypovitaminosis D does not have any effect on LPR in the Indian female population.

Study aimed to assess the level of 25-OH-cholecalciferol(vitamin D) and the relation with cholesterol, proteins and glycaemia levels in patients with cystic fibrosis. 58 patients underwent for the annual evaluations and were tested for vitamin D deficiency, as the centre�s protocol requires, besides dosage of cholesterol, glycaemia and proteins levels. Serum levels of 25-hydroxycholecalciferol were compared to levels of cholesterol, proteins and glycaemia, using Pearson correlation and logistic regression. The average value of 25-OH-cholecalciferol was 22,9 ng/mL, suggesting an important deficiency and different stages of 25-OH-cholecalciferol deficiency was found in the majority of patients. Nor a positive correlation neither negative relationship was found between vitamin D and cholesterol (r=0,23), glycaemia or proteins level. Vitamin D levels are not related to cholesterol or proteins in our study. Although cystic fibrosis is characterised by liposoluble vitamins deficiency and lipids impaired digestion, other factors influence the seric levels of vitamin D and lipids.

Abstract Aim: To study the vitamin D levels in toddlers with recurrent wheezing.Methods: In this prospective observational study, 108 children aged 1-3 years with recurrent wheezing and 41 healthy age and sex matched controls were included. The clinical, demographic, socio-economic, food habits, and sun exposure of both the groups were assessed. The serum levels of vitamin D were measured and Asthma predictive index (API) of all the cases was calculated. Spearman or Pearson correlation coefficients were used to see relationship of different variables with Vitamin D.Results: Among 108 cases and 41 controls we enrolled, majority of them had vitamin D deficiency or insufficiency. The difference in vitamin D levels in the two groups was not statistically significant (p=0.0619). We found no significant difference in the vitamin D levels between, urban and rural population, vegetarians and non-vegetarians, adequately and inadequately sun light exposed children. There was also no correlation between the vitamin D levels and the number of wheezing episodes in the last 1 year. There was no significant correlation between the number of criteria of API positive and the vitamin D levels.Conclusion: Our study showed that the overall prevalence of vitamin D deficiency is very high among toddlers with recurrent wheezing. We conclude that vitamin D rich diet and sunlight exposure cannot prevent vitamin D deficiency in Indian toddlers. National programme for universal supplementation of vitamin D is required to control this epidemic of vitamin D deficiency.

SummaryBackground:25 (OH) vitamin D3 (25(OH)D) and parathyroid hormone (PTH) are important regulators of calcium homeostasis. The aim of this study was to retrospectively determine the cut–off for sufficient 25(OH)D in a four-season region and the influence of age, seasons, and gender on serum 25(OH)D and PTH levels.Methods:Laboratory results of 9890 female and 2723 male individuals aged 38.8±22.1 years who had simultaneous measurements of 25(OH)D and PTH were retrospectively analyzed by statistical softwares. Serum 25(OH)D and PTH levels were measured by a mass spectrometry method and by an electrochemiluminescence immunoassay, respectively.Results:Mean serum 25(OH)D levels showed a sinusoidal fluctuation throughout the year and were significantly (p<0.01) higher in summer and autumn. On the other hand, PTH levels were significantly higher (p<0.01) in women and showed an opposite response to seasonal effects relative to 25(OH)D. Lowest levels of 25(OH)D were detected in people aged between 20 and 40 years whereas PTH hormone levels were gradually increasing in response to aging. The significant exponential inverse relationship that was found between PTH and 25(OH)D (PTH=exp(4.12–0.064*sqrt(25(OH)D)) (r=−0.325, R–squared=0.105, p<0.001)) suggested that the cut–off for sufficient 25(OH)D should be 75 nmol/L.Conclusions:Our retrospective study based on large data set supports the suitability of the currently accepted clinical cut–off of 75 nmol/L for sufficient 25(OH)D. However, the issue of assessing Vitamin D deficiency remains difficult due to seasonal variations in serum 25(OH)D. Therefore, PTH measurements should complement 25(OH)D results for diagnosing Vitamin D deficiency. It is imperative that seasonally different criteria should be considered in future.

Background: Spondyloarthritides (SpAs) encompass heterogeneous diseases sharing similar genetic background, pathogenic mechanisms, and phenotypic features. Vitamin D is essential for calcium metabolism and skeletal homeostasis. Some recent evidences reported supplemental functions of vitamin D, such as modulation of inflammatory reactions. Objective: To analyze published data about a possible association between vitamin D and SpAs. Results: Vitamin D could play a role in immune reactions, influencing both immune and adaptive response. Vitamin D deficiency is more frequent in SpAs than in general population: an active and more severe disease infers patients’ mobility and reduces sunlight exposure. Quiescent inflammatory bowel disease, frequently associated with SpAs, could worsen vitamin D deficiency. All the parameters related to UVB exposure are the most important determinants for vitamin D status and need to be considered evaluating the vitamin D levels in SpAs. Apart from musculoskeletal problems, patients affected by SpAs frequently suffer from other comorbidities, especially cardiovascular diseases and osteoporosis, and vitamin D status could have a relevance in this field. Bone is involved in SpAs with a dualistic role, coexisting trabecular bone resorption and new bone formation. It seems rational to monitor vitamin D levels in SpA subjects and to target it to global health threshold. Conclusion: Literature data were not completely in agreement about a possible relation between poor vitamin D status and onset or worse disease course of SpAs. In fact, these results come from cross-sectional studies, which affect our ability to infer causality. Therefore, large, randomized controlled trials are needed.
