title: 25-hydroxycholecalciferol serum levels in patients with Crohn's disease.
abstract: In 37 patients with Crohn's disease the 25-hydroxycholecalciferol (25-HCC) serum level, serum concentration of calcium and inorganic phosphate, and the enzyme activity of alkaline phosphatase were measured. Furthermore the activity index of Crohn's disease was determined in every patient. There was no statistically significant difference of 25-HCC serum levels in these patients compared to a healthy control group. Correspondingly most patients showed normal alkaline phosphatase enzyme activity and normal serum concentration of calcium and inorganic phosphate. No correlation between 25-HCC concentration and site of inflammation or activity index was found.
