The relationship of serum 25-hydroxycalciferol levels with the severity of the new COVID-19 coronavirus infection in pregnant women

Introduction Novel coronavirus infection (NCI) COVID-19 in women during pregnancy has a different course – from asymptomatic to severe and extremely severe. Associations between the severity of NCI serum level 25-hydroxycalciferol (25(OH)D), which is an active metabolite vitamin D, are currently being studied. There few data on association D deficiency with general population, even less reflecting 25(OH)D blood pregnant suffering varying degrees severity. Purpose research was conduct clinical laboratory comparisons, including Materials methods . Under observation there were 29 living Chelyabinsk region, who admitted maternity obstetric service infectious hospital for patients 3rd–4th wave pandemic. Group 1 consisted 16 COVID-19. 2 included 13 mild Serum levels these determined by chemiluminescent immunoassay. Results The statistically more likely be deficient while adequate latter not recorded. Discussion Vitamin may contribute prominent systemic response development cytokine storm cause Conclusions conducted demonstrated relationship women. We suggest that can considered as predictor
