Interleukin 6 (IL-6), which is involved in the cytokine storm phenomenon, is a therapeutic target in COVID-19, but monoclonal receptor antibody therapeutic agents such as tocilizumab have demonstrated mixed results. Could Vitamin D, which modulates IL-6, be more effective than currently deployed IL-6 antagonists, including tocilizumab, thereby presenting a useful therapeutic option in COVID-19? A narrative review of published trials examining the effect of Vitamin D administration in COVID-19 patients was conducted, and the theoretical basis for the use of tocilizumab as an IL-6 antagonist was compared with the immunomodulatory effect of Vitamin D on IL-6 production. Four of the six included studies reported a positive effect of Vitamin D on outcomes. While tocilizumab non-selectively blocks both anti-inflammatory and pro-inflammatory actions of IL-6, Vitamin D lowers immune cell IL-6 production, potentially reducing pro-inflammatory effects, but does not specifically target IL-6 receptors, avoiding any deleterious effect on the anti-inflammatory actions of IL-6. Vitamin D may have advantages over tocilizumab as an IL-6 immunomodulator, and, given that it is safe if administered under clinical supervision, there is a strong rationale for its use.
