Vitamin D insufficiency as a potential culprit in critical COVID-19 patients
Vitamin D has been implicated in the coronavirus disease- 2019 outcome. We aim to systematically explore the association of vitamin D serum levels with COVID-19 severity and prognosis. Patients with poor prognosis had significantly lower serum levels of vitamin D compared with those with a good prognosis. Diagnosis of vitamin C deficiency could be a helpful adjunct to assessing patients' potential of developing severe COVID-19.
