Abstract

Our study aimed to understand the link between baseline vitamin D levels at admission and in-hospital clinical outcome and 7-month all-cause mortality in patients hospitalized with COVID-19. Sixty-three percent of 636 Iranian patients had insufficient 25(OH)vitamin D baseline levels (<30 ng/mL) on admission. All patients were followed for 7 months on average. Insufficient baseline levels of vitamin D were associated with an increased risk of in-hospital mortality (P = .022), 7-month all-cause mortality (P = .047), and multiple-organ damage (P = .035) in patients with COVID-19. No association between other in-hospital complications and 25(OH)vitamin D levels was found. Copyright © 2024 Wolters Kluwer Health, Inc. All rights reserved.
