Biochemical markers in glucocorticoid-induced osteoporosis.
Following the introduction of corticosteroids as therapeutic agents in the 1950s, their use has been expanded so that today glucocorticoids are widely used. There are few studies in the literature directly aimed at describing the changes of bone markers following glucocorticoid administration. The interpretation of some of these investigations may be hampered by a number of confounding factors, whose influence is not always taken into consideration. In general, the effects of glucocorticoid administration are represented by a reduction in bone formation markers (particularly considering serum osteocalcin levels) and a trend to an increase or no change in bone resorption markers. The inconsistency of this last finding may be related to the time at which the observation is carried out and to the marker employed.
