Rhabdomyolysis may cause kidney failure by several mechanisms. The most important is the accumulation of myoglobin in the kidney tubules . [ 10 ] [ 11 ] [ 13 ] Normally, the blood protein haptoglobin binds circulating myoglobin and other heme-containing substances, but in rhabdomyolysis the quantity of myoglobin exceeds the binding capacity of ...
Statin-induced rhabdomyolysis is rare, occurring in less than 0.1% of people who take statins. [64] [65] [66] Statin induced rhabdomyolysis, as with other statin associated muscle symptoms, occurs most commonly in the first year of treatment but can occur at any time during treatment. [64]
Side effects of statins include muscle pain, increased risk of diabetes, and abnormal blood levels of certain liver enzymes. [5] Additionally, they have rare but severe adverse effects, particularly muscle damage, and very rarely rhabdomyolysis. [6] [7]
Clinical presentations of rhabdomyolysis. While statins are generally well-tolerated, severe adverse effects such as hepatotoxicity and myotoxicity may occur in rarity. Statin-induced hepatotoxicity can cause autoimmune hepatitis and an elevation in serum levels of hepatic enzymes such as alanine aminotransferase, impairing liver function. [20]
However, due to its relatively severe adverse effects in comparison to other statins, its market use was discontinued. The strengths of the available cerivastatin medicine ranged from 0.2 - 0.8 mg, resulting in an actual dose of 1.9 - 13.1 μg/kg body weight for which rhabdomyolysis has been reported. [14]
Common types of myopathy due to statins include myalgia, myositis, and rhabdomyolysis. Statins induce myopathy by inhibiting protein synthesis within the muscle. [6] Statin therapy tends to not show any histopathological differences, and thus a biopsy does not reveal too much about the damage. Often, the damage is found within the mitochondria.
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. [1] However, there are cases of SAAM in patients who have not taken statin medication, and this can be explained by the exposure to natural sources of statin ...
Common side effects include abdominal pain, nausea, headaches, and muscle pains. [6] Serious side effects may include rhabdomyolysis, liver problems, and diabetes. [6] Use during pregnancy may harm the baby. [6] Like all statins, rosuvastatin works by inhibiting HMG-CoA reductase, an enzyme found in the liver that plays a role in producing ...
