Brief Summary
Vitamin D deficiency is common in cystic fibrosis. Vitamin D deficiency frequently persists despite aggressive treatment with ergocalciferol, a vitamin D preparation also known as vitamin D2. Cholecalciferol, a vitamin D preparation also known as vitamin D3,may work better to increase vitamin D levels. Vitamin D is important for absorption of calcium from the diet and bone health. Vitamin D more recently has been found to play a role in regulating the normal inflammatory process. Since cystic fibrosis is a state of excessive inflammation, vitamin D may be playing a role in cystic fibrosis. We hypothesize: cholecalciferol will work better to increase vitamin D levels in patients iwth cystic fibrosis and that it will have an effect on markers of inflammation.
