Correlation of Vitamin-D with Inflammatory Markers in COVID-19 Patients

Great interest has been raised by the possible protective role of vitamin D in coronavirus disease 2019 (COVID-19), but objective data on 25(OH)vitamin D deficiency in hospitalized COVID-19 patients are not conclusive. The aim of this study was to determine the prevalence of 25(OH)vitamin D deficiency in COVID-19 patients admitted to an tertiary care hospital and explore its association with clinical outcomes and the markers of disease severity. In this single-observational descriptive study, 100 consecutive adult COVID-19 patients hospitalized in an tertiary care hospital were enrolled from March to April 2021. 25(OH)Vitamin D serum levels were assessed 48 h since hospital admission and categorized into: normal (?30 ng/mL), insufficient (less than30 - ?20 ng/mL), moderately deficient (less than20 - ?10 ng/mL), severely deficient (less than10 ng/mL).
