Osteoporosis

Glucocorticoids remain the leading cause of secondary osteoporosis, and oral steroid use in rheumatic disease has risen over the last twenty years despite steroid-sparing agents. This review covers how quickly bone is lost, why DXA systematically underestimates fracture risk on steroids, how much the underlying rheumatic disease contributes, the steroid-sparing evidence in SLE, GCA, PMR and ANCA vasculitis, and what the trial data actually support.
