Vitamin D deficiency (VDD) partly explains geographical differences in COVID-19 susceptibility, severity, and mortality. VDD among African-Americans, diabetics, hypertensive, and aged populations possibly explain the higher death rate, aggravated by cocooning. Vitamin D is pleiotropic, mediating bone metabolism, calcium homeostasis, and immune functions, whereas VDD is associated with inflammatory reactions and immune dysfunction, predisposing individuals to severe infections.
Vitamin D modulates innate and adaptive immunity via the expression of genes that code antimicrobial peptides (AMPs). And the expression of cluster of differentiation (CD)14, the co-receptor for epidermal toll-like receptor (TLR)4. AMPs stimulate TLR2 in macrophages, increasing the conversion of vitamin D into its active form by cytochrome P450 27B1. Antiviral properties of vitamin D-induced AMPs can shift the polarization of the adaptive immune response from helper T cells (Th)1 to the more regulatory Th2 responses that suppress immune over-reactivity by preventing cytokine storm, which is already demonstrated during the Spanish flu episode.
Vitamin D induces antiviral effects by both direct and indirect mechanisms via
- AMPs,
- immunomodulation,
- the interplay between major cellular and viral elements,
- induction of autophagy and apoptosis,
- variation of genetic and epigenetic factors.
The crosstalk between vitamin D and intracellular signaling pathways may operate as a primary regulatory action on viral gene transcription.
VDD may increase the likelihood of infection with enveloped viruses, including
- retrovirus,
- hepatitis, and
- dengue.
Key teaching points
Vitamin D induces antiviral effects by direct and indirect mechanisms via
- AMPs,
- immunomodulation,
- induction of autophagy, etc.
Epidemiology of VDD partly explains geographical differences in COVID-19
- susceptibility,
- severity, and
- mortality.
Global data correlates severe VDD with COVID-19 associated
- coagulopathy,
- disrupted immune response and
- mortality,
- reduced platelet count, and
- prolonged prothrombin time,
together suggesting benefits from supplementation. Many clinical trials are underway globally to delineate the role of vitamin D in both prevention and treatment of COVID-19.
