Abstract

Background: Vitamin D deficiency has been linked to various medical conditions such as bone loss, decreased mineralization, endocrine disorders, and central nervous system disorders, including epilepsy. Vitamin D deficiency is prevalent among patients with epilepsy (PWE). However, the specific association between vitamin D levels and age in PWE is unclear.

Objectives: Identify the relation between vitamin D level and age in PWE and evaluate factors that may play a role in seizure control.

Design: Retrospective analytical medical record review SETTING: Outpatient epilepsy research clinic in Saudi Arabia PATIENTS AND METHODS: Between November 2016 and April 2020, we selected eligible PWE aged older than 14 years whose vita-min D levels were recorded at least once after reviewing 1550 patient electronic files. We analyzed data on serum vitamin D level by age and other factors, vitamin D supplement use, seizure classification, and conducted a multivariate logistic regression to assess associations with seizure control.

Main outcome measures: Relationships between vitamin D levels and age and factors that might affect seizure control.

Sample size: 524 patients RESULTS: The prevalence of low serum vitamin D levels was high (86.8%). The median vitamin D level in all patients was low (38 nmol/L), and was lower in young PWE than in adult PWE (P<.01). Only 146 patients received vitamin D supplements. High vitamin D levels were associated with a 40% seizure reduction.

Conclusion: Vitamin D deficiency is underestimated in PWE in Saudi Arabia, and is more prevalent among young adults and patients on polytherapy than in other PWE. Patients with high vitamin D levels had good seizure control compared with those with low levels. The effect of vitamin D supplements on seizure control should be further investigated in randomized control trials.

Limitations: Retrospective study and no categorization by presence of supplementation.

Conflict of interest: None.

癫痫患者血清维生素D水平与年龄的关系:来自沙特阿拉伯癫痫中心的回顾性研究
背景:维生素D缺乏与多种疾病有关,如骨质流失、矿化减少、内分泌紊乱和中枢神经系统疾病,包括癫痫。维生素D缺乏症在癫痫患者(PWE)中很普遍。然而,PWE患者维生素D水平与年龄之间的具体关系尚不清楚。目的:确定PWE患者维生素D水平与年龄的关系,并评价可能在癫痫发作控制中起作用的因素。设计:回顾性分析医疗记录回顾设置:沙特阿拉伯癫痫门诊研究诊所患者和方法:2016年11月至2020年4月,在回顾1550例患者电子档案后,我们选择了年龄大于14岁且至少记录一次维生素D水平的合格PWE。我们分析了血清维生素D水平与年龄和其他因素、维生素D补充剂使用、癫痫发作分类的关系,并进行了多因素logistic回归来评估与癫痫发作控制的关系。主要结果测量:维生素D水平与年龄和可能影响癫痫控制的因素之间的关系。结果:血清维生素D水平低的患病率较高(86.8%)。所有患者的维生素D水平中位数较低(38 nmol/L),年轻PWE低于成年PWE(结论:维生素D缺乏症在沙特阿拉伯的PWE中被低估,在年轻人和接受多种治疗的患者中比其他PWE更普遍。与维生素D水平较低的患者相比,维生素D水平高的患者癫痫发作控制较好。维生素D补充剂对癫痫发作控制的作用有待进一步的随机对照试验研究。局限性:回顾性研究,没有根据补充物的存在进行分类。利益冲突:无。
