Necrotizing myopathy - The Myositis Association
网页Necrotizing myopathy is a newly defined form of idiopathic inflammatory myopathy, or myositis. Patients with necrotizing myopathy have muscle biopsies that show much less inflammation in the muscle tissue than polymyositis patients, but they have increased evidence of muscle cell death, or necrosis.
Features and Outcomes of Necrotizing Autoimmune Myopathy
网页Importance Necrotizing autoimmune myopathy (NAM) is characterized pathologically by necrotic muscle fibers with absent or minimal inflammation. It is often accompanied by statin therapy, connective tissue diseases, cancer, and autoantibodies specific for signal recognition particle (SRP) or 3-hydroxy-3-methylglutaryl–coenzyme A reductase (HMGCR).

网页2017年6月14日 · Necrotizing myopathy is a rare disorder of muscles with no known etiology in more than 50% of cases. Recognition of risk factors, identification of associated autoantibodies including SRP and HMGCR, timely muscle biopsy, and early aggressive immunotherapy are associated with improved outcomes.

网页Signs and Symptoms. The hallmark feature of people with immune-mediated necrotizing myopathy (IMNM) is the presence of proximal muscle weakness. Most affected people experience only weakness, and the presence of other (extra-muscular) symptoms, such as skin or lung manifestations, suggests that they may have another type of IIM rather than …

网页What are Immune-Mediated Necrotizing Myopathies? Immune-Mediated Necrotizing Myopathies (IMNM) can present in a very similar way to Polymyositis. In fact, until recently, most castes of IMNM were diagnosed as Polymyositis. However, in recent years, research has identified that in comparison to Polymyositis, those with IMNM can have:
