<unk>  (SAAM), also known as anti-HMGCR myopathy, is a very rare form of muscle damage caused by the immune system in people who take<unk>  medications. However, there are cases of SAAM in patients who have not taken<unk>  medication, and this can be explained by the exposure to natural sources of<unk>  such as red yeast rice, which is<unk>  rich. This theory is supported by the higher prevalence of<unk> -naive SAAM patients in Asian cohorts, who have<unk> -rich diets. The exact cause is unclear. A combination of consistent findings on physical examination, the presence of anti HMG-CoA reductase antibodies in a person with myopathy, evidence of muscle breakdown, and muscle biopsy diagnose SAAM. Treatment involves stopping the<unk> <unk>  medication and taking medication to suppress the immune system. SAAM is estimated to occur in 2-3 people out of every 100,000<unk> -treated individuals. It appears to be more common in people over the age of 50.
