PURPOSE
Considering the COVID-19 pandemic, vitamin D is a target of research and speculation. Lockdown or home isolation reduces sunlight exposition and increases the risk of vitamin D deficiency. Special attention is needed for older people at risk of both severe forms of COVID-19 and vitamin D deficiency. This review aims to highlight the association of vitamin D and COVID-19 in two instances, the direct influence of vitamin D on the immune system, and the indirect risks for other vitamin D deficiency-related diseases, such as musculoskeletal properties in older persons.
METHODS
We performed a narrative review.
RESULTS
Whether vitamin D deficiency is associated with COVID-19 poor prognosis, and if vitamin D supplementation may improve the post-infection outcomes is still unclear. In any case, the pandemic generates indirect burden, such as the sequence: home isolation, low sunlight exposition, vitamin D deficiency, and fragility fractures.
CONCLUSION
Therefore, it is time to debate how to optimize vitamin D status in older people, especially during the COVID-19 pandemic.
目的
鉴于新冠疫情，维生素D成为研究和推测的对象。封锁或居家隔离减少了阳光照射，增加了维生素D缺乏的风险。对于同时面临严重新冠病毒感染和维生素D缺乏风险的老年人，需要给予特别关注。本综述旨在突出维生素D与新冠病毒感染在两方面的关联，一是维生素D对免疫系统的直接影响，二是维生素D缺乏相关其他疾病的间接风险，如老年人的肌肉骨骼状况。
方法
我们进行了一项叙述性综述。
结果
维生素D缺乏是否与新冠病毒感染的不良预后相关，以及补充维生素D是否能改善感染后的结局仍不明确。无论如何，疫情产生了间接负担，例如居家隔离、阳光照射不足、维生素D缺乏和脆性骨折这样的连锁反应。
结论
因此，是时候讨论如何优化老年人的维生素D水平了，尤其是在新冠疫情期间。
