Diagnosis of patients with a LGMD-like presentation of anti-HMGCR myopathy is critical because these patients may respond favorably to immunotherapy, especially those with shorter disease duration. Anti-HMGCR myopathy can resemble LGMD. Anti-hydroxymethylglutaryl CoA reductase (HMGCR) myopathy is a subtype of myositis characterized by proximal muscle weakness, elevated serum creatine kinase (CK) levels, and autoantibodies recognizing HMGCR 1. Muscle biopsies revealed variable degrees of a dystrophic pathology without prominent inflammation. In an independent cohort of patients with anti-HMGCR myopathy, 17 of 51 (∼33%) patients were initially presumed to have a form of LGMD based on clinico-pathologic features but were ultimately found to have 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 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. HMGCR : Necrotizing autoimmune myopathy (NAM) is a serious but rare muscle disease strongly associated with autoantibodies to either signal recognition protein (SRP) or 3-hydroxy-3-methylglutaryl-CoA reductase (HMGCR).(1) NAM typically manifests with subacute proximal limb muscle weakness and persistently elevated serum creatine kinase (CK) concentrations, but slower onsets can occur and complicate diagnosis.

A pathogenic role of anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase (anti-HMGCR) antibodies has been proposed. Our objective was to assess efficacy of rituximab (RTX) in anti-HMGCR immune-mediated necrotizing myopathy. Methods. All patients who had been treated with RTX were retrospectively reviewed to assess features and outcome. Results. Three of 9 patients demonstrated Over the past decade, immune-mediated necrotizing myopathy has been recognized as a subcategory of idiopathic inflammatory myopathy characterized by myofiber necrosis in the absence of prominent inflammatory cells. 1 Autoantibodies against signal recognition particle (SRP) and 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) are thought to be associated with the development of immune 2020-03-07 · Although rare, antihydroxy-3-methylglutaryl-coenzyme A reductase (anti-HMGCR) myopathy is a severe adverse effect of statins, manifesting as myalgias, proximal muscle weakness, muscle cell necrosis and rhabdomyolysis.
Not all such patients are taking statins.

Centronuclear (CNM) and X-linked Myotubular Myopathies (XLMTM) are rare genetic disorders (also known as orphan diseases ). GNE myopathy is a very rare genetic condition that causes muscles in the arms and legs to become increasingly weak. It is also known by several other names This is a list of some of the most commonly encountered disorders.

NMS1 : Necrotizing autoimmune myopathy (NAM) is a serious, but rare muscle disease strongly associated with autoantibodies to either signal recognition protein (SRP) or 3-hydroxy-3-methylglutaryl-CoA reductase (HMGCR).(1) NAM typically manifests with subacute proximal limb muscle weakness and persistently elevated serum creatine kinase (CK) concentrations, but slower onsets can occur and 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.

Thomas R, Yeoh SA, Berkeley R, Woods A, Stevens M, Marino S, Radunovic A. BMC Rheumatol, 4:29, 30 Jun 2020 2020-01-08 · OBJECTIVE: To describe successful therapeutic strategies in statin-induced anti-HMGCR myopathy. METHODS: Retrospective data from a cohort of 55 patients with statin-induced anti-HMGCR myopathy, sequentially stratified by the presence of proximal weakness, early remission, and corticosteroid and IVIG use at treatment induction, were analyzed for optimal successful induction and maintenance of Immune-mediated necrotising myopathy (IMNM) is characterised by severe muscle weakness and necrosis with a paucity of inflammation on muscle biopsy.
Definite anti-HMGCR myop-athy is defined as positive anti-HMGCR autoanti-bodies, elevated serum CK levels, and proximal skeletal muscle weakness (16). Probable anti-HMGCR myopathy was defined for this study as positive anti-HMGCR, elevated CK levels, suggestive muscle biopsy findings with necrosis/regeneration or MAC depos- 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. Anti-HMGCR myopathy was first recognized and characterized in patients with a history of statin exposure and immune-mediated necrotizing myopathy. After the discovery of anti-HMGCR autoantibodies, several international groups identified and characterized more patients, expanding the phenotypic spectrum of this disease to include pediatric patients and young adults without statin exposure and those with a chronic myopathy resembling limb-girdle muscular dystrophy.
