Statins are one of the most commonly used medications to lower cholesterol and have been known to cause various side effects including myalgias, myopathies, and rhabdomyolysis. Statin-induced necrotizing autoimmune myopathy (SINAM), a subtype of inflammatory myopathy, is an exceedingly rare but severe side effect of statin use that manifests as progressive muscle weakness.

In a subgroup, it can trigger an autoimmune necrotizing myopathy 3 Dec 2020 Statin-associated necrotizing autoimmune myopathy Necrotizing autoimmune myopathy (NAM) is a severe adverse effect of statins. We report a 14 Dec 2019 While self-limited statin myopathy is relatively common, statin-induced necrotizing autoimmune myopathy (SINAM) is extremely uncommon, 5 May 2020 Statin-induced immune-mediated necrotizing myopathy, also known as anti-3- hydroxy-3-methylglutaryl-coenzyme A reductase (anti-HMGCR) Statin-associated autoimmune necrotizing myopathy is a rare but known clinical entity.

It should be considered Statins and Immune-Mediated Necrotizing Myopathy Statins are a well-recognized cause of a variety of skeletal myopathic effects, which generally resolve when discontinuing the treatment. Among autoimmune manifestations associated with statins, there is immune-mediated necrotizing myopathy (IMNM). ABSTRACT. Statins are widely prescribed medications to prevent cardiovascular events. While self-limited statin myopathy is relatively common, statin-induced necrotizing autoimmune myopathy (SINAM) is extremely uncommon, with incidence of two cases per million per year. Statins are widely used and lower the risk of death from cardiovascular causes.

Diagnosis is confirmed by positive anti-HMG-CoA reductase autoantibody.

Statins and Immune-Mediated Necrotizing Myopathy. Mauro Turrin 1. 1 Former Department of Internal Medicine, Ospedali Riuniti Padova Sud, Monselice (Padova), Italy. Abstract. Statins are a well-recognized cause of a variety of skeletal myopathic effects, which generally resolve when discontinuing the …

He was treated with high-dose corticosteroids and a short course of intravenous immunoglobulin with very mild improvement in symptoms. 2018-11-01 · This study aimed to clarify the phenotypes and therapeutic responses of statin-naïve anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) antibody-mediated necrotizing myopathy. Anti-HMGCR antibodies were tested with ELISA methodology in the sera sample of 98 patients meeting the idiopathic inflammatory myopathy criteria and with negative anti-signal recognition particle (SRP) antibody. Treatment of statin-associated autoimmune necrotizing myopathy can be challenging and requires immunosuppressive drugs.

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.

In some case, statins switch on, a process of autoimmune system which 10 Dec 2015 More recently, there have been reports of an immune-mediated necrotising myopathy associated with statin use. This autoimmune myopathy is Necrotizing autoimmune myopathy manifests In addition, statin discontinuation does not 18 May 2010 Recently, statins have been linked to a necrotizing myopathy that appears unrelated to any direct statin toxicity and that responds to 11 Jun 2015 These findings were consistent with statin-associated immune-mediated necrotising myopathy. After 6 months of treatment with high dose oral 26 Dec 2017 Necrotizing Autoimmune Myopathy (NAM) associated with 3-hydroxy-3- methylglutarylcoenzyme A Reductase.

The autoantibodies are probably not pathogenic, but merely indicative of the underlying immune disorder. The pathogenic mechanism is under investigation. 2020-12-29 Statin-associated myopathy comprises of a spectrum of conditions ranging from benign myalgias to statin-induced immune-mediated necrotizing myopathy. Statin-induced immune-mediated necrotizing myopathy is an autoimmune condition wherein there is a destruction of normal skeletal muscular architecture that can be severely debilitating if not recognized promptly. Among autoimmune manifestations associated with statins, there is immune-mediated necrotizing myopathy (IMNM). The present article summarizes the main features of statin-related IMNM, describing diagnosis, classification, epidemiology, treatment, and the main autoantibodies detected.
