BACKGROUND:

Vitamin D plays a seminal role in many homeostatic mechanisms.

In this study, we assessed the correlation between circulating vitamin D levels and mortality rates in critically ill patients.

METHODS:

All patients admitted to the intensive care units (ICUs) and internal medicine wards in a university-based hospital that required mechanical ventilation were admitted. Data collected included the underlying disease, basic hematological and biochemical blood test results, APACHE II scores and serum 25-hydroxyvitamin D [25(OH)D] levels. The primary end point was defined as all-cause mortality within 60 days from admission or from acute deterioration.

RESULTS:

Between December 2008 and June 2009, 130 patients were enrolled. Average vitamin D concentration was 14.04?±?6.9?ng/ml; 107 patients were vitamin D deficient (20?ng/ml (P?PDF is attached at the bottom of this page

Death rates for average

  • 12 ng (category < 20) = - - - - - -

  • 25 ng (category >20) = ** _

Strange: paper states overall mortality rate of 44% within 60 days of hospitalization for all patients.

Yet the graph seems to indicate 100% death rate within 60 days

Expect that seniors with a good level of vitamin D (say 40-50 ng/ml)

  1. Would been unlikely to have been in the ICU in the first place

  2. Would have gotten out of the ICU alive

    •     Note: this study excluded patients who were taking vitamin D
