Background To investigate the association between serum 25-hydroxyvitamin D levels and its effect on adverse clinical outcomes, parameters of immune function mortality due to a SARS-CoV-2 infection. Study design The hospital data 235 patients infected with COVID-19 were analyzed. Results Based CDC criteria, among our study patients, 74% had severe infection 32.8% vitamin sufficient. After adjusting for confounding factors, there was significant sufficiency reduction in severity, inpatient...
Without an adequate immune response, SARS-CoV2 virus can simply spread throughout the body of host. Two well-known immunonutrients are selenium (Se) and zinc (Zn). Se Zn deficiency might lead to inflammation, oxidative stress, viral entry into cells by decreasing ACE-2 expression; three factors that proposed be involved in COVID-19 pathogenesis. Thus, current study we aimed at evaluating correlation between serum status severity. Eighty-four patients were enrolled this observational study....
