DONATTI, Teresinha Lermen; KOCH, Vera Hermina Kalika; TAKAYAMA, Liliam  and  PEREIRA, Rosa Maria Rodrigues. Effects of glucocorticoids on growth and bone mineralization. J. Pediatr. (Rio J.) [online]. 2011, vol.87, n.1, pp.4-12. ISSN 0021-7557.

OBJECTIVE: To review the various mechanisms of glucocorticoid action and the ability of these agents to induce osteoporosis and growth deficits. SOURCES: A review of the scientific literature was conducted on the basis of a MEDLINE search using the keywords and descriptors “glucocorticoids,” “bone mineralization,” “growth,” and “side effects” and limited to articles published in the last decade. The references cited by these articles were used to identify relevant older publications, with an emphasis on landmark studies essential to an understanding of the topic. SUMMARY OF THE FINDINGS: Emphasis was placed on the actions of glucocorticoids on the hormones and cytokines that modulate linear growth. The end effects of glucocorticoids on the skeletal system are the result of systemic effects on bone metabolism and of direct actions on bone cells, which alter bone cell counts and predispose to bone loss. The mechanisms underlying catch-up growth and bone mass recovery after discontinuation of glucocorticoid treatment are discussed, followed by a review of diagnostic methods available for assessment of bone metabolism and mineralization and of measures for prevention and management of glucocorticoid-induced bone changes. CONCLUSION: Patient monitoring on a case-by-case basis plays an essential role in detection and, potentially, reversal of the damage associated with chronic glucocorticoid therapy.
