Vit D Assessment in Patients with COVID-19 Virus

Abstract

OVID-19 has emerged as a global pandemic affecting millions of people. Vitamin D deficiency is one of the risk factors for increased susceptibility to COVID-19. COVID-19 mainly affects the respiratory, cardiovascular, and gastrointestinal systems. It was found that a significant proportion of deaths occurred more than 2 weeks after the onset of symptoms suspected of being caused by cytokine storms Cytokine production and its role on the pathogenicity and host immune response in other important viral respiratory diseases such as those caused by influenza A and SARS-CoV-1 and MERS-COV. Vitamin D is known to play a key role in the maintenance of bone health and calcium-phosphorus metabolism, yet many other functions of this vitamin have been recently postulated, such as modulation of the immune response in both infectious and autoimmune diseases. Vitamin D includes fat-soluble steroids that are responsible for a wide spectrum of immunomodulatory, anti-inflammatory antifibrotic, and anti-oxidant actions. In humans, vitamin D3 (cholecalciferol) and vitamin D2 (ergocalciferol) are the most abundant subtype of vitamin D
