VitaminDWiki Summary

People with poor digestion (CKD, Diabetes, MS, etc) are not able to get much benefit from standard oral vitamin D‰%The study on this page shows if UV is given to those with CKD
Study on this page found with UV that:

  • More vitamin D gets into the bloodstream than with oral
  • Vitamin D receptor improved by 65%
    (which increases the active vitamin D actually getting into the cells)
  • CYP27B1 gene improved by 100%
    (which increases activation of Vitamin D in the Kidney )
  • CYP2R gene improved by 120%

BACKGROUND:
In chronic kidney disease (CKD) a deficiency of 1,25-dihydroxyvitamin D is common. The aim of this review was to compare vitamin D status after oral supplementation of vitamin D3 to that of serial suberythemal irradiation in end-stage kidney disease (ESKD) patients.

PATIENTS AND METHODS:
Ninety-five patients, with a mean age of 62 (range=35-82) years, were treated with a mean dose of 35,000 (20,000-60,000) IU vitamin D3 per week for a period of 18 months. Fourteen patients, with a mean age of 51 (range=41-57) years, were whole-body UVB irradiated for over 6 months. From 3 hemodialysis patients skin biopsies were performed.

RESULTS:
With oral supplementation 25(OH)D3 increased by 60%. With UV irradiation 25(OH)D3 increased by 400%. Gene expression analysis demonstrated an improvement in the vitamin D receptor (VDR) by 0.65 fold, in 1-alpha-hydroxylase (CYP27B1) by 1.0 fold, and in 25-hydroxylase (CYP2R) by 1.2 fold.

CONCLUSION:
Serial suberythemal UVB irradiation of patients with CKD on dialysis is capable to improve serum 25(OH)D3 and 1,25(OH)2D3 by enhancing the skin's ability to activate vitamin D.
