Statin Myopathy

This is the first that I've heard of statins inducing autoimmunity. But since food can (casein and wheat) why not statins?

Many different classes of medications can cause toxic myopathy. One of the most frequently implicated classes is the statins. Statin myotoxicity ranges from asymptomatic creatine kinase elevations or myalgias to muscle necrosis and fatal rhabdomyolysis. Statins may also cause an autoimmune myopathy requiring immunosuppressive treatment. The mechanisms of statin myotoxicity are unclear. If unrecognized in its early manifestations, complications from continued statin therapy may lead to rhabdomyolysis and death. Risk factors for myotoxicity include concomitant medication use and medical conditions, and the patient's underlying genetic constitution. We review these considerations along with the recommended evaluation and treatment for patients presenting with statin myotoxicity.

All medications can potentially induce autoimmunity and auto-reactivity but the ones carrying sulfa moieties are apparently the worse. Obviously genetics and environment factors play a large role in triggering autoimmunity but drugs can be compelling and powerful instigators because they are synthetic, strong chemicals that our bodies may not naturally encounter.

--Septra/sulfamethoxazole; sulfa-based antibiotics
--Diuretics ('water pills'): Hydrochlorothiazide (HCTZ), Chlorthalidone, Furosemide (Lasix), Bumetanide (Bumex) [all diuretics except potassium-sparing Diuretics (Amiloride, Spironolactone)]
--Hydralazine (may trigger SLE/lupus in 7%+ users)
--Glipizide, Glyburide, Chlorpropamide, etc (all sulfonyurea anti-diabetes drugs)
--Imitrex/sumatriptan and other migraine triptans
--Lisinopril, Ramipril (Altace), Fosinopril and all ACE-inhibitors except captopril (ARBs are fine)
--Beta blockers -- atenolol, metoprolol, propranolol, bisoprolol, sotalol, etc (all BBs except Coreg/carvedilol; CCB Verapamil is fine)
--Etc
