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. Among the 122 patients with immune-mediated necrotizing myopathy associated with anti-HMGCR autoantibodies in the cohort, eight patients with severe cardiovascular disease and/or diabetes were using PCSK9 inhibitors for hyperlipidemia. This is a phase 2, double-blinded, randomized, placebo-controlled, multi-center trial of Gamunex-C IVIG as mono-therapy for HMGCR necrotizing myopathy.

Among the 122 patients with immune-mediated necrotizing myopathy associated with anti-HMGCR autoantibodies in the cohort, eight patients with severe cardiovascular disease and/or diabetes were using PCSK9 inhibitors for hyperlipidemia. This is a phase 2, double-blinded, randomized, placebo-controlled, multi-center trial of Gamunex-C IVIG as mono-therapy for HMGCR necrotizing myopathy. Up to 10 treatment-naïve patients will be enrolled and randomized to receive either Gamunex-C IVIG dosed at 2g/kg or placebo at week 0 and week 4.

It presents with severe proximal muscle weakness, high creatine kinase levels and muscle fiber necrosis. Like other forms of myositis, patients with necrotizing myopathy may experience the following symptoms: Weakness in the muscles closest to the center of the body, such as the forearms, thighs, hips, shoulders, neck, and back Difficulty climbing stairs and standing up from a chair Difficulty lifting More recently, a subset of cases of immune-mediated necrotising myopathy has been found to have antibodies against HMGCR. It is often an aggressive and debilitating myopathy and has a complex pathogenesis characterised by fibre necrosis, usually with minimal associated inflammation.

Therefore, these autoantibodies are found in patients exposed to Statin medication [3]. 2020-03-01 Yes. Necrotizing Autoimmune Myopathy (NAM) and Immune-Mediated Necrotizing Myopathy (IMNM) refer to the same type of idiopathic inflammatory myopathy. You may also see the new subtypes listed as the name of the disease, such as anti-SRP myopathy, anti-HMGCR myopathy… 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.
