Appropriate use of steroids for patients with generalized Myasthenia Gravis: an international Delphi study.

Background: Oral corticosteroids (OCS) are commonly used in the management of autoimmune Myasthenia Gravis (MG), often in high doses for prolonged periods. Exposure to OCS is associated with significant and cumulative adverse effects. There is currently no universal consensus on the approach to OCS use in MG. Objectives: To reach a multinational consensus on the appropriate use of OCS in MG, including the role of treatment approaches to minimize dose and support tapering. Design: This modified Delphi study established consensus among a panel of 70 general neurologists/neuromuscular specialists from eight countries over two rounds of survey to establish best practice principles regarding the use of OCS in MG. Methods: The current literature on OCS use in MG was reviewed. Topics of interest were identified, and a modified Delphi consensus process was created. A steering committee of six experts in MG proposed statements for testing with the wider panel over two rounds of surveys. Consensus was reached if at least 75% agreed or strongly agreed on a 4-point Likert scale. Results: Consensus was achieved for all 37 final statements. These statements covered principles of OCS use, including a target for long-term use of ⩽5 mg/day; the role of biologic treatments in minimizing required OCS dose; the need for individualization of approach according to patient factors; and the need for detailed guidance regarding how and when to taper OCS dose. Conclusion: These findings reinforce a shift in the management of MG, advocating for the judicious and sparing use of OCS against the backdrop of expanding therapeutic options. As additional evidence-based data emerge, these recommendations should be updated.
