59 Studies suggest multiple hypotheses (Table 1). Ca2+ leak is a mechanism common to other skeletal myopathies (e.g. muscular dystrophy). Defining the cellular process that underlies statin induced myopathy is the first step in the development of co-therapies to improve statin compliance. 2019-08-01 2020-06-02 2018-03-24 2020-03-01 Statin-associated autoimmune myopathy (SAAM), also known as anti-HMGCR myopathy, is a very rare form of muscle damage caused by the immune system in people who take statin medications.

6 Although myopathy can refer to any muscular disease, the recent clinical advisory on the use and safety of statins differentiated myalgia as muscle Multiple pathophysiological mechanisms may contribute to statin myotoxicity. This review focuses on a number of them. The prevention of statin-related myopathy involves using the lowest statin dose required to achieve therapeutic goals and avoiding polytherapy with drugs known to increase systemic exposure and myopathy risk. The precise mechanisms underlying statin-associated myopathy are not well understood; however, theories do exist. One proposed mechanism suggests that decreased cholesterol concentrations secondary to statin therapy may result in alterations in myocyte membrane cholesterol.

Moreover, in the sarcoplasma, statins can reduce the resting chloride channel conductance, as well as lactate efflux. The mechanism by which statins cause muscle toxicity or statin-associated muscle symptoms (SAMS) is not well understood, and the term SAMS is used to imply that these symptoms are not always truly caused by statin use.

Posted 21st October 2015 by Cyprotex. A recent paper by Schirris et al., 2015 has finally uncovered a mechanistic understanding of statin-induced myopathy. This type of toxicity is the most common side effect of the statins and severity ranges from muscle pain in up to 26% of patients to very rare incidents of life threatening rhabdomyolysis. A robust pathophysiologic animal model shows that statins decrease strength and increase cytosolic Ca2+ by increasing both mitochondrial Ca2+ permeability and Ca2+ release from sarcoplasmic reticulum.

Myopathy is among the well documented and the most disturbing adverse effects of statins. The underlying mechanism is still unknown. Mitochondrial dysfunction related to coenzyme Q10 decline is one of the proposed theories. The present study aimed to investigate the mechanism of atorvastatin-induced myopathy in rats. The precise mechanisms underlying statin-associated myopathy are not well understood; however, theories do exist.

One proposed mechanism suggests that decreased In the sarcoplasma, statins activate MAPK and diminish the RhoA/AKT/mTOR/PGC-1α pathway. All these effects contribute to activate apoptosis, proteolysis, and muscle remodeling. Moreover, in the sarcoplasma, statins can reduce the resting chloride channel conductance, as well as lactate efflux.

Summary: Statin-associated myopathy is a common patient complaint and can include myalgia (muscle aches and pains) and myositis The exact mechanism for statin-associated myopathy is not fully known and may be multifactorial.

A robust pathophysiologic animal model shows that statins decrease strength and increase cytosolic Ca2+ by increasing both mitochondrial Ca2+ permeability and Ca2+ release from sarcoplasmic reticulum. As a result, the earliest pathologic change in statin myotoxicity is compatible with simple necrosis and intracellular membrane accumulation. Statin-associated autoimmune myopathy (SAAM), also known as anti-HMGCR myopathy, is a very rare form of muscle damage caused by the immune system in people who take statin medications.
