Glucocorticoid-induced osteoporosis is the most frequent cause of secondary osteoporosis. Glucocorticoids cause a rapid bone loss in the first few months of use, but the most important effect of the drug is suppression of bone formation. The administration of oral glucocorticoid is associated with an increased risk of fractures at the spine and hip. The risk is related to the dose, but even small doses can increase the risk. Patients on glucocorticoid therapy lose more trabecular than cortical bone and the fractures are more frequent at the spine than at the hip. Calcium, vitamin D and activated forms of vitamin D can prevent bone loss and antiresorptive agents are effective for prevention and treatment of bone loss and to decrease fracture risk. Despite the known effects of glucocorticoids on bone, only a few patients are advised to take preventive measures and treat glucocorticoid-induced osteoporosis. RESUMOOsteoporose Induzida por Glicocorticóide. A osteoporose induzida por glicocorticóides é a causa mais freqüente de osteoporose secundária. Os glicocorticóides causam uma perda óssea rápida nos primeiros meses de uso da medicação; entretanto, o seu efeito mais importante é uma supressão significativa da formação óssea. A administração oral de glicocorticóides está associada a um aumento no risco de fraturas na coluna e no quadril. O risco é dose dependente; entretanto, mesmo doses baixas de glicocorticóides podem aumentar o risco de fraturas. Os pacientes em uso de glicocorticóides perdem mais osso trabecular que osso cortical; em conseqüên-cia, as fraturas são mais freqüentes na coluna que no quadril. O uso concomitante de cálcio e vitamina D ou formas ativas da vitamina D previne a perda óssea, e as drogas anti-reabsortivas são efetivas na prevenção e tratamento da perda óssea e diminuem o risco de fraturas. Apesar de os efeitos deletérios dos glicocorticóides sobre o osso serem bastante conhecidos, poucos pacientes são orientados ou recebem tratamento preventivo associado à terapia com glicocorticóides.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
