Re: all things vitamin D
Multiple sclerosis patients have a diminished serologic response to vitamin D supplementation compared to healthy controls
"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."
