Abstract
Purpose of the review
We discuss the evidence behind the use of glucocorticoids in myositis including a discussion of mechanism of action, dosing, tapering, and duration of therapy as well as glucocorticoid-related adverse events that are particularly important in myositis patients.
Recent findings
Studies showing reduction in mortality rates after the use of glucocorticoids, better outcomes in patients treated with glucocorticoids compared to those who did not, and reduction of inflammation in muscle biopsies provide low level evidence to support use of glucocorticoids in myositis. Early initiation of therapy is associated with better functional outcomes. Use of intravenous methylprednisolone in patients with severe disease may lead to quicker recovery and reduction in long-term glucocorticoid exposure. Steroid-related myopathy and osteoporosis are glucocorticoid side effects that are particularly relevant in myositis.
Summary
The optimal dose and duration of glucocorticoid therapy in myositis currently remain elusive, and this review emphasizes the need for better quality studies in this area.
