Objective To elucidate the common and distinct clinical features of immune-mediated necrotising myopathy (IMNM), also known as necrotising autoimmune myopathy associated with autoantibodies against signal recognition particle (SRP) and 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR). Methods We examined a cohort of 460 patients with idiopathic inflammatory myopathies (IIMs) through a

1 – 3 It is often associated with autoantibodies recognizing the signal recognition particle (SRP) or 3-hydroxy-3-methylglutaryl-CoA reductase (HMGCR). 2 Many aspects of the pathophysiological mechanisms of IMNM remain unknown. 2016-10-01 · In 2010, antibodies to 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGCR) were identified in patients with immune-medicated necrotizing myopathy (IMNM), 63% of whom were on statin therapy . This seminal finding was closely followed by a number of studies supporting the association of anti-HMGCR autoantibodies with IMNM and statin use [15] , [16] . 2018-11-01 · In 2010, an anti-200/100kd autoantibody was detected in a group of necrotizing myopathy patients with high rate of statin exposure. The 200/100 kd protein was soon recognized as 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGCR) whose expression was up-regulated with statin treatment.

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. It is a rare side effect of statins, distinct from the more commonly recognized statin-induced myalgia, that is challenging to diagnose and treat.

Res. 65 , 276–281 (2017). Objective: We examined a cohort of Australian patients with statin exposure who developed a necrotizing autoimmune myopathy (NAM) associated with a novel autoantibody against 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) and describe the clinical and therapeutic challenges of managing these patients and an optimal therapeutic strategy. Methods: Clinical, laboratory, EMG, and Objective.

iNM is a recently emerging subtype of IIM and often associated with specific autoantibodies such as anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) and anti-signal recognition The novel anti-HMGCR antibody, which was discovered in 2010, is a promising diagnostic marker for statin-associated NAM.12 Nearly all patients with statin-induced necrotizing autoimmune myopathy have positive anti-HMGCR antibodies with tropism to the catalytic site of HMGCoA reductase. The study included patients who were part of the longitudinal cohort of the Johns Hopkins Myositis Center, Baltimore.

The HMGCR antibody is a very specific finding to the autoimmune variety of statin myopathy, as studies have shown it to be absent in traditional statin-related myopathy. Idiopathic inflammatory myopathy (IIM) is currently categorized into PM, DM, anti-synthetase syndrome, inclusion body myositis, immune-mediated necrotizing myopathy (iNM) and non-specific myositis [1, 2]. iNM is a recently emerging subtype of IIM and often associated with specific autoantibodies such as anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) and anti-signal recognition The novel anti-HMGCR antibody, which was discovered in 2010, is a promising diagnostic marker for statin-associated NAM.12 Nearly all patients with statin-induced necrotizing autoimmune myopathy have positive anti-HMGCR antibodies with tropism to the catalytic site of HMGCoA reductase.
