Interaction of Vitamin D and Corticosteroid Use in Hospitalized COVID-19 Patients: A Potential Explanation for Inconsistent Findings in the Literature.
Study Goal
The researchers aimed to examine the interaction between vitamin D and corticosteroids as a potential explanation for inconsistent findings regarding vitamin D's benefit in hospitalized COVID-19 patients.
Results Summary
The study found that existing research on vitamin D and COVID-19 outcomes is inconsistent, with most studies being observational and not accounting for corticosteroid use. Small randomized trials have been insufficiently powered to balance corticosteroid use between study arms.

Vitamin D is an important immune-modulator with anti-inflammatory properties. While this prohormone has been studied extensively in the prevention and treatment of COVID-19, findings have been inconsistent regarding its overall benefit in patients hospitalized with COVID-19. Most studies to date have been observational in nature, not accounting for the use of corticosteroids. Furthermore, the few randomized clinical trials designed to examine the effect of vitamin D supplementation on COVID-19 outcomes have been relatively small and thus insufficiently powered to assure a balance of corticosteroid use between study arms. The current perspective addresses the interaction of vitamin D and corticosteroids as a potential explanation for the divergent results reported in the literature. Future research on vitamin D and COVID-19 will benefit by considering this interaction, especially among hospitalized patients requiring oxygen and mechanical ventilation.
