Anti-HMGCR Myopathy Payam Mohassela and Andrew L. Mammenb,∗ aNational Institutes of Health, NINDS, Bethesda, MD, USA bNational Institutes of Health, NIAMS, Bethesda, MD, USA Abstract. Anti-HMGCR myopathy was ﬁrst recognized and characterized in patients with a history of statin exposure and immune-mediated necrotizing myopathy. Anti-SRP myopathy Anti-HMGCR myopathy Total 18 16 Mean age, years (range) 29.7 (11–72) 54.6 (19–81) Female/male 15/3 9/7 African American 11/17 0/3 Clinical manifestation Proximal weakness 16 15 Shoulder weakness 3 2 Hip girdle weakness 2 4 Neck flexor weakness 3 2 Myalgia 9/12 0/0 Cutaneous 5/12 0/1 Dysphagia 10/14 2/2 Dyspnea 2/12 1/2 Immune-mediated necrotising myopathy (IMNM) is characterised by severe muscle weakness and necrosis with a paucity of inflammation on muscle biopsy. Around 60% of cases are associated with antibodies to the signal recognition particle (SRP) or 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR); the remainder are seronegative.

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, and antibody-negative IMNM. 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 Anti-HMGCR myopathy makes up less than 10% of these cases.

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.

Anti-HMGCR myopathy may resemble limb-girdle muscular

Anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) immune-mediated necrotizing myopathy is a subtype of idiopathic inflammatory myopathy which may be associated with statin exposure. It presents with severe proximal muscle weakness, high … 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 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 spect … 2020-01-08 2021-03-12 2020-10-22 2019-06-01 Necrotizing autoimmune myopathy: an emerging entity in the spectrum of inflammatory myopathies M. Ishaq Ghauri, M. Shariq Mukarram* & Noman Khalid HMGCR is pharmacologic target of the Statin drugs. 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.

Are effector T cells mediating muscle destruction in patients

Inflammatory myopathies constitute a heterogeneous group of disorders Statin-associated autoimmune necrotizing myopathy is a rare but known clinical entity. Suspicion of this entity should prompt a thorough workup to include Antibodies against HMG-CoA reductase (HMGCR) are associated with necrotizing autoimmune-myopathy and can be detected in about 25% of these patients.
