The Bcl-2 indexes of anti-HMGCR myopathy patients were ∼45%, which were higher than those of other IIMs (Fig. 1N, p < 0.001). Endomysial Bcl-2-positive lymphocytes were more frequently observed in anti-HMGCR-positive myopathy cases than in other IIMs (p < 0.001).

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

It presents with severe proximal muscle weakness, high creatine kinase levels and muscle fiber necrosis. 3-Hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) is a key enzyme in the cholesterol biosynthesis pathway. Objective. A pathogenic role of anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase (anti-HMGCR) antibodies has been proposed.

Objective.

HMGCR myopathy has demonstrated that they generally tend to have more severe disease and a worse prognosis in response to immunotherapies compared to the older, statin-exposed group [26]. More recently, several pediatric patients with anti-HMGCR myopathy have been identiﬁed [27, 28]. When treated with immunotherapies, most pediatric

Recently, auto-antibodies (AAbs) to the enzyme, 3-hydroxy-3-methylglutaryl-CoA reductase (HMGCR) was shown to be a MSA that was strongly associated with immune mediated necrotising myopathy (Arthritis Rheum. 2010 Sep;62(9):2757-66. doi: 10.1002/art.27572).

Not all such patients are taking statins. Conclusions: Patients with HMGCR antibody–associated myopathies present with weakness and muscle discomfort and often have damage to both perimysial connective tissue and muscle fibers, with necrosis and myonuclear pathology. Only a minority of patients with HMGCR antibody–associated myopathies have a history of statin exposure.
