Vitamin D sufficiency, a serum 25-hydroxyvitamin D at least 30 ng/mL reduced risk for adverse clinical outcomes in patients with COVID-19 infection
Vitamin D sufficiency, a serum 25-hydroxyvitamin D at least 30 ng/mL reduced risk for adverse clinical outcomes in patients with COVID-19 infection
Retrospective 235 hospitalized patients showing a significant association between vitamin D sufficiency and reduction in clinical severity.For patients over 40, mortality was 9.7% with 25(OH)D levels >30ng/mL, versus 20% for <30ng/mL.A significant reduction in serum CRP, an inflammatory marker, along with increased lymphocytes percentage suggest that vitamin D sufficiency may help modulate the immune response possibly by reducing the risk for cytokine storm in response to this viral infection.
