Multiple Sclerosis patients need more vitamin D to get same blood level response – Aug 2015

Multiple sclerosis patients have a diminished serologic response to vitamin D supplementation compared to healthy controls

Mult Scler August 18, 2015 1352458515600248

VitaminDWiki Summary
Gave 5,000 IU of vitamin D daily to two groups for 3 months
There was a 6.7 ng less response in the MS group
Possible reasons - by VitaminDWiki
  1. MS, like many other diseases, consumes vitamin D
  2. MS patients did not get outdoors as much (less vitamin D from the sun)
    (this was not mentioned in the abstract)
  3. MSers have genes which deminish the VitaminD efficiency in the body
  4. MSers have less Magnesium (just a guess)
  5. Drugs being taken by MSers reduce vitamin D

Response to 5,000 IU daily

Background: Vitamin D insufficiency is a risk factor for multiple sclerosis (MS), and patients do not always show the expected response to vitamin D supplementation.

Objective: We aimed to determine if vitamin D supplementation leads to a similar increase in serum 25-hydroxyvitamin-D (25(OH)D) levels in patients with MS and healthy controls (HCs).

Methods: Participants in this open-label study were female, white, aged 18–60 years, had 25(OH)D levels ⩽ 75 nmol/l at screening, and had relapsing–remitting MS (RRMS) or were HCs. Participants received 5000 IU/day of vitamin D3 for 90 days. Utilizing generalized estimating equations we examined the relationship between the primary outcome (serum 25(OH)D level) and the primary (MS versus HC status) and secondary predictors.

Results: For this study 27 MS patients and 30 HCs were enrolled. There was no significant difference in baseline 25(OH)D level or demographics except for higher body mass index (BMI) in the MS group (25.3 vs. 23.6 kg/m2, p=0.035). In total, 24 MS subjects and 29 HCs completed the study. In a multivariate model accounting for

  • BMI,
  • medication adherence, and
  • oral contraceptive use,

MS patients had a 16.7 nmol/l (95%CI: 4.2, 29.2, p=0.008) lower increase in 25(OH)D levels compared with HCs.

Conclusions: Patients with MS had a lower increase in 25(OH)D levels with supplementation, even after accounting for putative confounders.
