Study on Serum Vitamin D Levels in Patients with Bronchial Asthma

Background: Asthma is the most common chronic respiratory disease among children characterized by reversible airway obstruction. Vitamin D plays an important role in many immune and allergic diseases and it may have a role in asthmatic patients, however this association yet remains uncertain. The present study was designed to assess the level of serum Vitamin D in patients with bronchial asthma and it’s correlation with disease severity.Methods: A prospective observational study was performed from April 2019 to February 2020 in the Paediatric OPD of LNMC and JK Hospital Bhopal. All 90 children with physician diagnosed bronchial asthma (mild, moderate and severe) aged 10 to 18 years of both genders who have come in the OPD (total enumeration sampling) during the above mentioned period were enrolled in to the study. The patients were grouped on the basis of Vitamin D sufficiency and Vitamin D levels were correlated with disease severity.Results: The study comprised 54 boys (60%) and 36 girls (40%) with mean age of 15.1±3.96. Out of 90 children enrolled, 46 had good control over asthma and 37 had uncontrolled asthma. As regards asthma control, 25-OH Vitamin D was lowest among patients with uncontrolled asthma.Conclusions: Vitamin D deficiency was highly prevalent in asthmatic patients and there was a direct and a significant relationship between serum Vitamin D levels, severity of asthma, control of asthma, serum IgE levels and blood eosinophils count. Thus, measuring serum levels of Vitamin D followed by supplementation could be considered in the routine assessment of patients with bronchial asthma.

Background: Bronchial asthma is a common chronic inflammatory disorder of the airways in childhood. Vitamin D, initially described as a vitamin that regulated calcium homeostasis, has also been shown to exert important antimicrobial effects and is also a potent immune system regulator having a potential role in various allergic diseases. The main objective of this study was to look the levels of vitamin D in children with bronchial asthma and to study the co relationship between vitamin D levels and severity of asthma.Methods: This study included 80 (40 asthmatic children and 40 healthy controls) children aged between 4 and 15 year. Serum vitamin D levels where determined and compared between the two groups. The association between vitamin D levels and severity of asthma was studied in the asthmatic children.Results: Among 40 asthmatic children the mean serum vitamin D level was 16.6±11.56 ng/ml, while as the mean vitamin D levels in healthy control subjects was 24.225±2.764 ng/ml and the difference between the two groups was statistically significant (p=0.001). Vitamin D deficiency was highly prevalent in asthmatic patients and there was a direct and a significant relationship between serum vitamin D levels and severity of asthma.Conclusion: In this study, vitamin D levels were considerably lower in children with asthma than in healthy children. Also, in this study vitamin D deficient asthma patients have more severe asthma than the patients who have sufficient vitamin D levels.

The Mean

Background: Bronchial asthma is one of the most common chronic diseases. In India, bronchial asthma has 66% frequency of reported exacerbations. Vitamin D has action on pro-inflammatory mediators and smooth muscle function and proliferation, which has direct relevance for lung function in asthma.Methods: The cross sectional observational study was conducted in the Department of Medicine, Government Medical College Jammu for 10 months from January 2018-August 2018. 50 Patients of 18-60 years with diagnosis of bronchial asthma on the basis of clinical and radiological signs were included, while age matched 50 controls years free from any disease and morbidity were included and assessed for vitamin D levels.Results: The mean serum vitamin D level was significantly low at 26.13±4.91 ng/ml in patients, while 39.67±4.03 ng/ml was the mean vitamin D level of controls. The vitamin D levels of mild and moderate (persistent) asthma patients was seen lower than those of the controls.Conclusions: Vitamin D deficiency is highly prevalent in patients during exacerbations of bronchial asthma. It is also associated with lower lung functions and increased number of exacerbations. Thus improving vitamin D status may be effective in the prevention and treatment of bronchial asthma and exacerbations.

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.

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.
