Vitamin D Deficiency and ARDS after SARS-CoV-2 Infection

Male gender, age over 40 years, cancer, diabetes mellitus, and chronic respiratory and cardiovascular disease have each been associated with increased severity of disease, including ARDS, after SARS-CoV-2 infection. We hypothesize that nutrition might also play a role. Vitamin D (25OHD) deficiency has previously been linked to a greater susceptibility to viral infection, ARDS, and pneumonia.3,4 Since 25OHD deficiency is both highly prevalent and easily treatable and the morbidity, mortality, and costs of SARS-CoV-2 related ARDS are great, we wanted to explore whether 25OHD levels might be associated with an increased risk of the development of ARDS due to SARS-CoV-2.
