In contrast to most of previously reported pediatric anti-3-hydroxy-3-methylglutaryl-coenzyme A reductasemyopathy, he showed little response to immunotherapies.
Although risk factors for daptomycin-associated myopathy are poorly defined, creatine phosphokinase (CPK) monitoring and temporary discontinuation of 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors, or "statins," has been recommended.
Potential Pathogenic Role of Anti-Signal Recognition Protein and Anti-3-hydroxy-3-methylglutaryl-CoA Reductase Antibodies in Immune-Mediated Necrotizing Myopathies.
Self-limited statin myopathy can be distinguished from statin-associated autoimmune myopathy because patients with the former do not have autoantibodies recognizing 3-hydroxy-3-methylglutaryl-coenzyme A reductase.
Pathogenic role of anti-signal recognition protein and anti-3-Hydroxy-3-methylglutaryl-CoA reductase antibodies in necrotizing myopathies: Myofiber atrophy and impairment of muscle regeneration in necrotizing autoimmune myopathies.
Identification of anti-HMGCR antibodies in statin-exposed patients with myopathy appears to be helpful both for differential diagnosis and for treatment strategy.
Combinations of fibrates and 3-hydroxy-3-methylglutaryl-coenzyme A reductase inhibitors are effective, but because of safety concerns related to myopathy and rhabdomyolysis, it is important to consider the possibility of pharmacokinetic interactions when such combinations are used.
