title: Levels of vitamin D-metabolites in a case of acro-osteolysis syndrome.
abstract: On the initial examinations of a 17-year-old boy with acro-osteolysis syndrome, the levels of serum 25-hydroxycholecalciferol (25OHD) were low, whereas serum levels of 1,25-dihydroxycholecalciferol (1,25(OH)2D) were normal. Administration of 1 alpha-hydroxycholecalciferol (1OHD) failed to improve the osteoporosis, although the serum 25OHD level rose to normal. It is unlikely that impaired bone remodeling due to abnormal vitamin D-metabolism was a primary defect in our patient.
