Prospective Intervention Study on Vitamin D in Patients With Cystic Fibrosis

Summary

The vast majority of Cystic Fibrosis (CF) patients worldwide are vitamin D insufficient. There is no evidence of benefit of vitamin D supplementation for CF patients yet. However, descriptive cross-sectional studies suggest that vitamin D might be beneficial with respect to bone health, as well as to the newly described "non-classical" functions of vitamin D such as the potential anti-diabetic and immunomodulatory effects. To prove causation, and to determine which serum vitamin D concentration is optimal for CF patients, vitamin D supplementation interventional studies are needed, such as our trial.

DIETARY_SUPPLEMENT

Supplementation with vitamin D2/D3

Patients younger than 16 years of age are administered 35,000 IU ergo-/chole-calciferol per week divided into doses 5000 IU per day as a starting dose that is further adjusted by serum 25-hydroxy vitamin D concentration monitoring. The intervention time is 3 months, followed by 2-months wash-out period when patients do not take any more extra vitamin D but they are still monitored. Patients 16 or more years of age are administered 50,000 IU ergo-/chole-calciferol per week divided into doses 7150 IU per day as a starting dose that is further adjusted by serum 25-hydroxy vitamin D concentration monitoring.
