FDA wrote:FDA has been investigating reports of cognitive impairment from statin use for several years. The agency has reviewed databases that record reports of bad reactions to drugs and statin clinical trials that included assessments of cognitive function.
The reports about memory loss, forgetfulness and confusion span all statin products and all age groups. Egan says these experiences are rare but that those affected often report feeling “fuzzy” or unfocused in their thinking.
In general, the symptoms were not serious and were reversible within a few weeks after the patient stopped using the statin. Some people affected in this way had been taking the medicine for a day; others had been taking it for years.
What should patients do if they fear that statin use could be clouding their thinking? “Talk to your health care professional,” Egan says. “Don’t stop taking the medication; the consequences to your heart could be far greater.”
Simvastatin attenuates increases in cardiorespiratory fitness and skeletal muscle mitochondrial content when combined with exercise training in overweight or obese patients at risk of the metabolic syndrome.
...there was an increased risk of incident diabetes with atorvastatin (adjusted hazard ratio 1.22, 95% confidence interval 1.15 to 1.29), rosuvastatin (1.18, 1.10 to 1.26), and simvastatin (1.10, 1.04 to 1.17).
do not forget, it is not being used by MS patients for ANY cardiovascular effects.cheerleader wrote:Serum inflammation numbers (like c reactive protein) are a much better indicator ocardiovascular or endothelial risk, than LDL.
Purpose of review: This review discusses the spectrum of myopathies associated with statin use, with special attention given to a recently identified statin-associated autoimmune-necrotizing myopathy. The clinical characteristics of these patients, pathologic findings, associated autoantibody and immunogenetic risk factors are discussed.
Recent findings: In the past several years, a novel form of autoimmunemyopathy associated with statin use has been described. Patients with this form of myositis have unique clinical, pathologic and pathophysiologic features when compared with those with self-limited statin toxic myopathy. An autoantibody directed against HMG-CoA reductase (HMGCR), the pharmacologic target of statins, characterizes the disease and can be used in clinical practice to identify these patients and direct therapy. Still, many questions remain to be answered regarding the pathogenic mechanisms at play, risk factors for developing the disease, long-term prognosis and effects of rechallenge with statins or other cholesterol-lowering drugs.
Summary: Statins can cause a spectrum of muscle diseases, most of which are self-limited and improve with discontinuation of the offending agent. In a subgroup, an autoimmune necrotizing myopathy develops that persists after discontinuation of statins. Specific autoantibody testing can help identify these patients in clinical practice and determine the need for immunosuppressive therapy.
