Statin-Related Necrotizing Autoimmune Myositis: More Than Myalgia

Statins are widely prescribed for cardiovascular disease, and, in general, are well tolerated by most people. Most side effects related to statins are mild, with some side effects also considered a nocebo effect. Occasionally, statins can be associated with severe side effects. One of the more severe adverse events is immune-mediated necrotizing myositis, which is both difficult to diagnose and treat. The symptoms can be debilitating, and aggressive immunosuppressive therapy is the best-recognized method of treatment of this complication. In this case report, we discuss the clinical features, diagnosis, and treatment of this disease entity with an emphasis on the need for rapid diagnosis and aggressive treatment to help reduce morbidity.
