  • “Collectively these results provide unequivocal evidence that vitamin D insufficiency and deficiency are highly prevalent among critically ill patients.”
  • “These results demonstrate current replacement regimes are grossly inadequate.”


He ends by citing studies showing death in the ICU and the CCU is 2-3 times higher for the vitamin D deficient.

Vitamin D metabolism and deficiency in critical illness.

Vitamin D deficiency is highly prevalent and has been associated with a diverse range of chronic medical conditions in the general population.
In contrast, the prevalence, pathogenesis and significance of vitamin D deficiency have received little attention in acute medicine.
Vitamin D deficiency is seldom considered and rarely corrected adequately, if at all, in critically ill patients.
Recent recognition of the extra-skeletal, pleiotropic actions of vitamin D in

  • immunity,
  • epithelial function and
  • metabolic regulation

may underlie the previously under-recognized contribution of vitamin D deficiency to typical co-morbidities in critically ill patients, including

  • sepsis,
  • systemic inflammatory response syndrome and
  • metabolic dysfunction.

Improved understanding of vitamin D metabolism and regulation in critical illness may allow therapeutic exploitation of vitamin D to improve outcome in critically ill patients.
