Settings: multicenter, double-blind, phase 3 trial (apparently vitamin D worked in phase 2 trials).

Patients:
- 1059 patients were enrolled within 12 hours of ICU admission. The patients had to have risk factors warranted ICU admisions (pneumonia, sepsis, mechanical ventilation, shock, pancreatitis, etc.).
- Vitamin D deficiency was defined as plasma level < 20 ng/ml
Intervention:
- 531 patients received a single oral dose of 540,000 IU of vitamin D3 within 2 hours after randomization
Comparison
- 528 patients received placebo
Outcome
- 90-day all-cause mortality

Study Results:

Total SOFA score was similar in both groups (5.6 vs. 5.4).
On day 3, mean plasma vitamin D was higher (47 ng/ml) in treatment group vs 11 ng/ml in placebo group
90-day all cause mortality was similar. Treatment group was 23.5% vs. 20.6% for placebo (95% CI, −2.1 to 7.9; P = 0.26).
Vitamin D-related adverse events were similar in both groups.

Discussion:

This trial enrolled patients early in their critical illness compared to phase 2 trial which enrolled patients after 3 days in the ICU.
This phase 3 trial also enrolled mostly medical-related illness, whereas 75% of patients in phase 2 had either surgical or neurology-related illnesses.

Conclusion:

Early administration of high dose vitamin D did not improve 90-day all cause mortality.
