3(4) 267–274 (2016). 6. Thus, the presence of anti-HMG CoA reductase antibodies in someone who uses a statin and has myopathy strongly supports the diagnosis. CK levels increase to 10-100 times above normal (2000-20,000 IU/L) in more than 90% of cases. Electromyography (EMG) typically demonstrates a myopathic pattern of findings.

In contrast, anti-HMGCR myopathy is mostly seen in the setting of statin exposure and less commonly has extra-muscular involvement [1,2]. Autoantibody-negative autoimmune necrotizing myopathy remains poorly described, but they present with similar clinico-pathological features but lack the autoantibodies.

Finally, antibodies directed against 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) were found at high levels (1658UA/ml vs. normal<13.0UA/ml), resulting in diagnosis of necrotizing autoimmune myopathy (NAM).

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.

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. 2020-10-22 · Shovman, O. et al. Anti-HMGCR antibodies demonstrate high diagnostic value in the diagnosis of immune-mediated necrotizing myopathy following statin exposure.

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.
