50 adults in ICU – 56% of whom were vitamin D deficient (< 15 ng?)
RCT Injection of 150,000 or 300,000 IU of vitamin D (to all?)
3X less death rate in those who got enough vitamin D to change PTH level
Note: PTH will not change if
1) already have high level of vitamin D, or 2) did not get enough vitamin D
Note: Oral or topical dose will work just as well as injection in most cases
and topical "may" be faster
Note: One surgeon will not give elective surgery until the patient gets a loading dose of vitamin D
His "score card" is much better for surgeries with patients having lots of vitamin D

- Overview Loading of vitamin D contains the following
If a person is, or is suspected to be, very vitamin D deficient a loading dose is typically given
- Loading = repletion = quick replacement (previously known as Stoss)
- Loading doses range in size from 100,000 IU to 1,000,000 IU of Vitamin D3
- The size of the loading dose is a function of body weight - see below
Unfortunately, some doctors persist in using Vitamin D2 instead of D3
- Loading may be done as quickly as a single day, to as slowly as 3 months.
It appears that spreading the loading dose over 4-20 days is a good compromise
- Loading is typically oral, but sometimes by injection (I.M,)
- The loading dose persists in the body for about 3 months
The loading dose should be followed up with continuing maintenance
Unfortunately, many doctors fail to follow-up with the maintenance dosing.
- As about 1 in 300 people have some form of mild allergic reaction to vitamin D supplements,
it appears prudent to test with a small amount of vitamin D before giving a loading dose
- The causes of a mild allergic reaction appear to be: (in order of occurance)
1) lack of magnesium - which can be easily added
2) allergy to capsule contents - oil, additives (powder does not appear to cause any reaction)
3) allergy to the tiny amount of D3 itself (allergy to wool) ( alternate: D3 made from plants )

To determine the effect of two doses of intramuscular cholecalciferol on serial serum 25-hydroxy-vitamin-D levels and on pharmacodynamics endpoints: calcium, phosphate, parathyroid hormone, C-reactive protein, interleukin-6, and cathelicidin in critically ill adults.
Prospective randomized interventional study.
Tertiary, academic adult ICU.
Fifty critically ill adults with the systemic inflammatory response syndrome.
Patients were randomly allocated to receive a single intramuscular dose of either 150,000 IU (0.15 mU) or 300,000 IU (0.3 mU) cholecalciferol.
MEASUREMENTS AND MAIN RESULTS:
Pharmacokinetic, pharmacodynamic parameters, and outcome measures were collected over a 14-day period or until ICU discharge, whichever was earlier. Prior to randomization, 28 of 50 patients (56%) were classified as vitamin D deficient. By day 7 after randomization, 15 of 23 (65%) and 14 of 21 patients (67%) normalized vitamin D levels with 0.15 and 0.3 mU, respectively (p=0.01) and by day 14, 8 of 10 (80%) and 10 of 12 patients (83%) (p=0.004), respectively.
Secondary hyperparathyroidism was manifested in 28% of patients at baseline. Parathyroid hormone levels decreased over the study period with patients achieving vitamin D sufficiency at day 7 having significantly lower parathyroid hormone levels (p<0.01).
Inflammatory markers (C-reactive protein and interleukin-6) fell significantly over the study period.
Greater increments in 25-hydroxy-vitamin-D were significantly associated with greater increments in cathelicidin at days 1 and 3 (p=0.04 and 0.004, respectively). Although in-hospital mortality rate did not differ between the groups, patients who did not mount a parathyroid hormone response to vitamin D deficiency had a higher mortality (35% vs 12%; p=0.05). No significant adverse effects were observed.
A single dose of either dose of intramuscular cholecalciferol corrected vitamin D deficiency in the majority of critically ill patients. Greater vitamin D increments were associated with early greater cathelicidin increases, suggesting a possible mechanism of vitamin D supplementation in inducing bactericidal pleiotropic effects.
