Non-classical actions of Vitamin D are involved in regulation of the immune system including a role in mitigation of excessive inflammation. We hypothesized that vitamin D deficiency existing prior to SARS-CoV-2 infection could contribute to patients developing severe pulmonary compromise as a result of dysfunctional hyperinflammation. Serum vitamin D concentrations of patients experiencing such severe COVID-19 manifestations that they required ICU care at any point of their hospitalization were compared to serum vitamin D concentrations of patients achieving discharge without the need for any ICU care. Having serum vitamin D < 20 ng/mL was significantly associated with increased COVID-19 severity, p=0.001. It is conjectured that population groups know to have low serum vitamin D should be prospectively screened for deficiency and if found emergently treated. Such action could both decrease the maximum severity suffered by infected individuals and lessen the strain on medical resources by decreasing the percentage of COVID-19 hospital admissions requiring ICU care.
