Physicians should be aware of its different clinical phenotypes so that they can recognize it early and promptly initiate glucocorticoids, the mainstay of therapy. Clinicians should also be familiar with the toxicity of glucocorticoids and how to manage adverse effects. Tocilizumab, an interleukin 6 receptor inhibitor, is emerging as a glucocorticoid-sparing treatment, though its long-term safety and efficacy are still under study.
