Abstract: It is known that vitamin D has been found to decrease incidence of viral respiratory infections, as well as have effects on multiple cytokines involved in immunomodulation and the bradykinin/renin-angiotensin system. Recently, data was released showing a correlation between baseline vitamin D deficiency status and increased risk of contracting COVID-19. Separate analysis shows that many of the deleterious effects of COVID-19 may be due to the bradykinin/RAS system, and that vitamin D is one plausible treatment option to modulate these effects. Studies are currently ongoing to determine if vitamin D supplementation of those hospitalized with COVID-19 has a beneficial effect on patient outcomes. Objective: To determine if those hospitalized with COVID-19 with baseline vitamin D deficiency, have worse outcomes during their stay than those who are not vitamin D deficient at baseline. Design, Setting, and Participants: This is a retrospective cohort study at an urban academic medical center which included patients with a 25-hydroxycholecalciferol level measured within one year before being tested for COVID-19 and hospitalized from March 9th to September 7th, 2020. Exposures: Vitamin D deficiency was defined by the last measurement of 25-hydroxycholecalciferol less than 20 ng/mL before COVID testing (within one year). Main Outcomes and Measures: The primary outcomes investigated include length of stay, need for supplemental oxygen, ICU admission, need for invasive life support (mechanical ventilation, vasopressors, dialysis), and discharge status (discharged alive vs. death).
