Introduction and Aim: Vitamin D, besides its classical physiological functions, exerts effects on brain, prostate, breast, colon, pancreas, and immune cells due to the ubiquitous presence of its receptors. Hypovitaminosis D predisposes individuals to various micro and macro vascular complications of metabolic syndrome and diabetes mellitus. Despite speculations regarding implications of its deficiency on the cardio metabolic health of general/ susceptible population, its role remains underexplored in the Indian population.   Materials and Methods: This cross-sectional study carried out in Biochemistry Department of the institution, recruited 219 patients (after obtaining written consent) of both genders above18 years who underwent Vitamin D testing. Blood samples obtained were assayed for HbA1c, C Reactive protein, thiol and lipid. Kruskal Wallis test and Spearman correlation were employed for statistical analysis.   Results: Significantly low HDL and high atherogenic index of plasma (AIP) were observed in males with vitamin D deficiency. Significant inverse correlation of vitamin D with CRP and total cholesterol (among vitamin D deficient males) was observed. A significant inverse correlation between serum HDL and AIP and a significant direct correlation between triglyceride and AIP were observed irrespective of their vitamin D status. Heat map showed marginally elevated lipid parameters among vitamin D insufficient males.   Conclusion: Vitamin D may emerge as a surrogate marker in risk stratification of patients with diabetes and dyslipidaemia. More insights are required to assess the gender specific susceptibility to dyslipidaemia and atherosclerosis in relation to vitamin D levels.

Abstract. We aim to assess the prevalence of vitamin D deficiency (VDD) in patients scheduled for bariatric surgery (BS), and to identify factors that might be associated with VDD. We conducted a cross-sectional observational study involving all consecutive patients scheduled for BS from 2017 to 2019. The exclusion criteria were missing data for vitamin D levels, intake of vitamin D supplements in the 3 months prior to serum vitamin D determination, and renal insufficiency. A total of 206 patients (mean age and body mass index [BMI] of 34.9 ± 10.7 years, and 44.3 ± 6.99 kg/m2, respectively) met the inclusion criteria and were enrolled for data analysis. VDD (<19.9 ng/mL), severe VDD (<10 ng/mL), and vitamin D insufficiency (20–29.9 ng/mL) were present in 68.8 %, 12.5 %, and 31.2 % of patients, respectively. A significant inverse correlation was found between vitamin D levels and initial BMI, parathyroid hormone, and homeostatic model assessment of insulin resistance (r = −0.280, p < 0.05; r = −0.407, p = 0.038; r = −0.445, p = 0.005), respectively. VDD was significantly more prevalent in patients with higher BMI [−0.413 ± 0.12, CI95 % (−0.659; −0.167), p = 0.006], whereas no significant association between hypertension [−1.005 ± 1.65, CI95 % (−4.338; 2.326), p = 0.001], and diabetes type 2 (T2D) [−0.44 ± 2.20, CI95 % (−4.876; 3.986), p = 0.841] was found. We observed significant association between female sex and levels of vitamin D [6.69 ± 2.31, CI95 % (2.06; 11.33), p = 0.006]. The present study shows that in patients scheduled for BS, VDD deficiency is common and was associated with higher BMI, and female sex.

AbstractIntroductionLow serum levels of vitamin D have been associated with hypertension worldwide. Hypovitaminosis D has been observed even in countries with high incidence of sunlight all year round. Several studies demonstrated a high prevalence of deficiency/insufficiency of vitamin D in adolescents.ObjectiveTo investigate the association between the nutritional status of vitamin D with anthropometric measures and blood pressure in overweight adolescents.MethodsThis a descriptive and cross-sectional study with overweight adolescents of both sexes aged 12–19 years. The anthropometric data, biochemical profile, blood pressure and serum vitamin D dosage were analyzed. The chi-squared test for verification of association and Student’s t-test to compare medians between variables were used.ResultsThere were high frequencies of hypovitaminosis D (34%) and hypertension (43.3%) in overweight adolescents. We observed an inverse correlation between serum vitamin D levels and BP (r = −0.28, p = 0.005). Patients with desirable serum vitamin D had lower body mass index values (31.3 kg/m2 vs. 33.9 kg/m2; p < 0.02), waist circumference (95.2 cm vs. 101.1 cm; p < 0.03), waist-to-height ratio (0.58 vs. 0.61; p < 0.03) and systolic blood pressure (120 mm Hg vs. 127.6 mm Hg; p = 0.007).ConclusionsHigh frequency of vitamin D deficiency is associated with increased BP and adiposity in overweight adolescents.

Objective: To assess the levels of Vitamin D in patients with Chronic Rhinosinusitis (CRS) and its correlation with disease severity Methods: The study is an analytical cross -sectional study of patients with Chronic Rhinosinusitis (CRS) and the serum levels of Vitamin D in them.Controls have been used to compare the level of Vitamin D in healthy versus diseased population Results: There is an inverse correlation between severity of chronic rhinosinusitis and serum Vitamin D levels amongst the various subtypes of CRS. Conclusion: This study has observed that Vitamin D levels may have a denitive role in pathogenesis and severity of Chronic Rhinosinusitis. On review of literature, it was noted that very few Studies have discussed this issue.

Background: The risk factors for asthma exacerbations are well understood. However, the effect of vitamin D levels on number of asthma exacerbations per year is not clearly studied. The objective of the study was to find out the association of serum vitamin D levels and asthma risk factors on asthma exacerbations. Methods: In this study, ninety-nine subjects from 5 to 15 years of age were recruited at an episode of acute exacerbation. It was a cross sectional study and carried out from 2012 to 2015. Pulmonary function test was done by spirometry. Asthma exacerbation was labeled when forced expiratory volume/ forced vital capacity (FEV1/FVC) ratio was less than 80% (American Thoracic Society). Global Initiative for Asthma (GINA) guidelines were used to classify asthma into mild, moderate and severe persistent asthma. Serum vitamin D levels were measured by chemiluminescence method. Pearson Chi-square test was applied and p value (p<0.05) was considered as statistically significant. Results: Children who had exposure to animal dander had significantly lower asthma exacerbations per year (p-value <0.046). There was no significant association between vitamin D levels and number of exacerbations per years (p-value <0.099). Asthma was prevalent in girls of low socioeconomic status (SES) compared to males. However, there was no significant association between smoke, exercise, home environment, food allergies, weather, pollen and dust with asthma exacerbations. Conclusion: Low levels of vitamin D were not associated with increased number of asthma exacerbations per year. However, children exposed to animal dander had lesser number of exacerbations per year (p-value <0.046). Keywords: Asthma; Vitamin D; Children; Exacerbations, Risk factors.

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.
