Itamin D from the skin and diet is metabolized in the lier to 25-hydroxyitamin D (Figure 1), which is used to determine a patient's itamin D status1,2,3,4; 25-hydroxyitamin D is metabolized in the kidneys by the enzyme 25-hydroxyitamin D-1-hydroxylase (CYP27B1) to its actie form, 1,25-dihydroxyitamin D.1,2,3,4 The renal production of 1,25-dihydroxyitamin D is tightly regulated by plasma parathyroid hormone leels and serum calcium and phosphorus leels.1,2,3,4 Fibroblast growth factor 23, secreted from the bone, causes the sodium–phosphate cotransporter to be internalized by the cells of the kidney and small intestine and also suppresses 1,25-dihydroxyitamin D synthesis.5 The efficiency of the absorption of renal calcium and of intestinal calcium and phosphorus is increased in the presence of 1,25-dihydroxyitamin D (Figure 1).2,3,6 It also induces the expression of the enzyme 25-hydroxyitamin D-24-hydroxylase (CYP24), which catabolizes both 25-hydroxyitamin D and 1,25-dihydroxyitamin D into biologically inactie, water-soluble calcitroic acid.2,3,4
