phosphokinase (CPK) of 8200 IU/L, and positive urine myoglobin. Despite Objective: Necrotizing autoimmune myopathy (NAM) is a rare side-effect of statin therapy. We report the case of a patient who developed statin-induced NAM with a review of the clinical presentation and management of this rare entity. Statin-induced necrotizing autoimmune myopathy (IMNM) is an autoimmune disorder induced by anti-3-hydroxy-3-methylglutaryl-coenzyme-A reductase (anti-HMGCR) antibodies. We performed a retrospective clinical, histological, and radiological evaluation of 5 patients with a 3-year therapeutic follow-up. ….

Interesting Presentation of Statin-induced Necrotizing Myopathy Introduction: It is well know that statins can be associated with myopathy, myalgias and 28 Sep 2020 ated necrotizing myositis, anti-3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGCR) myopathy is a rare disease that occurs in 0.9 to 1.4 7 Mar 2020 We report an uncommon case of an autopsy-proven anti-HMGCR necrotising myopathy predominately affecting pharyngeal muscles in an older 30 Oct 2014 Abstract · Background. Statins have recently been reported to cause a rare autoimmune inflammatory and/or necrotic myopathy that begins or 9 Apr 2015 Recently, these medications have been associated with a necrotizing autoimmune myopathy (NAM). Statin-associated NAM is characterized by Statins are medications with great use. One of the side effects of medications is myopathy.
The review aims to define this heterogeneous entity and summarize the salient clinical, laboratory, and muscle biopsy findings, in order to facilitate the diagnosis and treatment of this condition. Recent findings Statin Statin-induced immune-mediated necrotizing myopathy, also known as anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase (anti-HMGCR) myopathy, is an inflammatory myopathy that is triggered by statin exposure and persists after statin discontinuation.

Statin-induced necrotizing autoimmune myopathy Exposure to statins prior to onset was significantly higher in patients with necrotizing myopathy (82%) as compared to those with dermatomyositis (18%), polymyositis (24%), and inclusion-body myositis (38%) seen in the same time period.
However, a rare and severe form of statin-induced necrotizing autoimmune myopathy (SINAM) has recently been described and can lead to debilitating weakness, often requiring immunosuppressive therapy. Statin-associated necrotizing myopathy is a symmetric proximal muscle weakness associated with extreme elevations of CK. It is common in males and can occur after months of statin use. It is associated with necrosis on muscle biopsy and the presence of anti-HMG-CoA reductase antibodies.

Statin-induced necrotizing myopathy has been linked to an antibody against the 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) protein, which is up-regulated in regenerating fibers. 5 In a study conducted by Christopher-Stine and associates, 6 exposure to statin therapy preceded the development of muscle symptoms and persisted long after the myotoxin was discontinued in more than 60% Statins can cause muscle related adverse events. 2-11% patients can have mild myalgia and myopathy, however necrotising myopathy is extremely rare (0.1%). Anti-HMCGCR antibodies are associated with statin induced IMNM. IMNM has a protracted course and can continue for years after stopping statins. Long term Immunosuppression is required in IMNM.
