Giant-Cell-Arteritis

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.

A 2026 review of steroid-sparing therapy across the GCA–PMR spectrum: glucocorticoids still induce remission but drive substantial cumulative toxicity, so the field has pivoted to IL-6 receptor inhibition (tocilizumab in GCA, sarilumab in PMR) and JAK inhibition (upadacitinib now approved for GCA) — none of which reliably restores treatment-free remission, against a backdrop of weak monitoring tools and GCA-specific vascular-damage risk.
