evaluating the level of vitamin d in iraqi covid-19 patients and its association with biochemical parameters

Vitamin d deficiency is widespread in iraq country. infectious rate with covid-19 was increased in our country. aim of this study to was to show more info on the relation between serum vitamin d level and infection’s severity and its relation per other biomarker. this cross-sectional descriptive type that made in covid-19 infected persons (n=90) attending abograib hospital, from july 2021 to february 2022, 2020, who were confirmed for covid-19 infection with rt-pcr. divided according to the severity as not severe & severe. in this study, 90 patients infected with covid-19 (age of the patients range from (18 - 65) years old were studied. there were 37 as not severe infected group (13female, 24 male), and 53 severe infected as 21 females, and 32 male. level of serum vit. d significantly lesser in severe group than those in not severe group (14.2 ± 5.23vs. 31.11± 8.72 ng/ml) respectively. serum d-dimer, ferritin, and crp parameters are significantly lower in in severe group than those in not-severe group (2.23 ± 1.51 vs 0.45 ± 0.32), (620.31 ± 189.56 vs 298.1±194.74), and (63.81 ± 35.2 vs 16.53 ± 12.82) respectively. vitamin d level was negatively correlated with d-dimer, ferritin, and crp levels. this study showed that serum level of vit. d was lesser in severe group, and it is negatively correlated with other inflammatory marker as d dimer, ferritin, crp.
