Abstract

Background: Vitamin D deficiency has been declared a public health problem for both adults and children worldwide. Asthma and related allergic disorders are leading causes of morbidity in children. The objective of this study was to estimate Vitamin D levels in children suffering from asthma and allergic rhinitis in North Kerala. Objectives: (1) To evaluate Vitamin D levels among children between the age group 5 and 18 years suffering from asthma and/or allergic rhinitis. (2) To study the factors associated with low levels of Vitamin D and (3) to study the correlation between Vitamin D levels, immunoglobulin E (IgE), and absolute eosinophil count (AEC). Materials and Methods: This is a retrospective analysis of hospital data in which data of children between the age group 5 and 18 years attending the pulmonology outpatient department of a tertiary care hospital in North Kerala are captured. The study period was 6 months from March 01, 2021, to August 31, 2021. Detailed clinical history, physical examination, and laboratory investigations including complete blood cell count, IgE, and 25 dihydroxyvitamin D3 (Vitamin D) level were done. Diagnosis of allergic rhinitis and asthma is made on the clinical presentation by an experienced pulmonologist. Family history of asthma or allergic rhinitis was also recorded. Data were entered into Microsoft Excel, and analysis was done using Epi Info 7. Means and standard deviation were calculated, and correlation was assessed between Vitamin D levels, IgE, AEC, and age of the children. Results: Thirty percent of children in the study group had Vitamin D deficiency, 56% had insufficient values, and 14% had normal values. Most of the children with low Vitamin D levels had raised values for IgE and AEC, but the association was not statistically significant. Conclusion: Most of the children in this part of the state presenting with respiratory allergy have low or insufficient levels of Vitamin D. This may be one of the reasons for poor control of symptoms and such children may require Vitamin D supplementation along with optimal treatment of respiratory allergy.
南印度过敏性鼻炎和哮喘儿童的维生素D水平:一项横断面研究
背景:维生素D缺乏症已被宣布为全球成人和儿童的公共卫生问题。哮喘和相关过敏性疾病是儿童发病的主要原因。本研究的目的是估计喀拉拉邦北部患有哮喘和过敏性鼻炎的儿童体内的维生素D水平。目的:(1)评估5 - 18岁哮喘和/或过敏性鼻炎患儿的维生素D水平。(2)研究维生素D水平低的相关因素;(3)研究维生素D水平与免疫球蛋白E (IgE)、绝对嗜酸性粒细胞计数(AEC)之间的相关性。材料和方法:这是对医院数据的回顾性分析,其中收集了北喀拉拉邦一家三级保健医院肺病门诊部5至18岁年龄组儿童的数据。研究时间为6个月,从2021年3月1日至2021年8月31日。详细的临床病史、体格检查和实验室检查,包括全血细胞计数、IgE和25二羟基维生素D3(维生素D)水平。过敏性鼻炎和哮喘的诊断是由经验丰富的肺科医生根据临床表现做出的。哮喘或过敏性鼻炎家族史也有记录。数据输入到Microsoft Excel中,并使用Epi Info 7进行分析。计算平均值和标准差,并评估维生素D水平、IgE、AEC和儿童年龄之间的相关性。结果:研究组中30%的儿童维生素D缺乏,56%维生素D不足,14%维生素D正常。大多数维生素D水平低的儿童的IgE和AEC值升高,但这种关联在统计学上不显著。结论:大多数出现呼吸道过敏的儿童体内维生素D含量偏低或不足,这可能是症状控制不佳的原因之一,这类儿童可能需要补充维生素D,同时对呼吸道过敏进行最佳治疗。
