Statin-associated necrotizing autoimmune myopathy.
Summary of "Statin-associated necrotizing autoimmune myopathy."
Necrotizing autoimmune myopathy (NAM) is a severe adverse effect of statins. We report a 66-year-old Caucasian female who had progressive proximal muscle weakness after treatment with statins. Results of a muscle biopsy showed necrotizing myopathy with minimal inflammatory cell infiltrate and increased major histocompatibility class I antigen expression in muscle fibers. The clinical and laboratory parameters improved significantly with immunosuppressive treatment. Although it is a rare event, statin-induced NAM should be included as a differential diagnosis of myopathies.

Statin medications have recently been shown to cause not only a toxic myopathy but also an immune-mediated necrotizing myositis. Before the discovery of a specific anti-HMG-CoA reductase antibody occu...
We report a 49-year-old patient with necrotizing myopathy and a right renal mass. After laparoscopic radical nephrectomy, a remission of myopathy was seen. Pathologic evaluation of the nephrectomy spe...
Necrotizing myopathy with pipestem capillaries is a form of chronic inflammatory myopathy, with histopathology showing necrotizing myopathy, minimal cellular infiltration, and microangiopathy. A 30-ye...
Many patients treated with statins are considered statin-resistant because they fail to achieve adequate reduction of low density lipoprotein cholesterol (LDL-C) levels. Some patients are statin-intol...
The risk of myopathy and rhabdomyolysis is considerably increased in statin users with end-stage renal failure (ESRF). Uremic toxins, which accumulate in patients with ESRF, exert cytotoxic effects th...
A major contributor to frailty and immobility in the elderly is the age related loss of muscle mass (sarcopenia). Cardiovascular disease (CVD) is the leading cause of mortality in the elde...
There is a significant proportion of patients complaining of muscle symptoms while on statin therapy who have a measurable difference in muscle strength or endurance and whose muscle biops...
The proposed study will focus on possible effects of statins on muscle strength and why they become tired more easily, quality of life, and measurements to understand why muscles are not a...
The purpose of this study is to investigate the mechanism of statin-related myopathy by evaluating muscle samples before and after statin exposure.
Statins (such as simvastatin or Zocor) are the most effective and widely prescribed medications to lower cholesterol levels and reduce the frequency of heart attacks, cardiac deaths and st...
Medical and Biotech [MESH] Definitions
Experimental animal models for human AUTOIMMUNE DISEASES OF THE NERVOUS SYSTEM. They include GUILLAIN-BARRE SYNDROME (see NEURITIS, AUTOIMMUNE, EXPERIMENTAL); MYASTHENIA GRAVIS (see MYASTHENIA GRAVIS, AUTOIMMUNE, EXPERIMENTAL); and MULTIPLE SCLEROSIS (see ENCEPHALOMYELITIS, AUTOIMMUNE, EXPERIMENTAL).
Inflammatory disease of the THYROID GLAND due to autoimmune responses leading to lymphocytic infiltration of the gland. It is characterized by the presence of circulating thyroid antigen-specific T-CELLS and thyroid AUTOANTIBODIES. The clinical signs can range from HYPOTHYROIDISM to THYROTOXICOSIS depending on the type of autoimmune thyroiditis.
A loss of mucous substance of the mouth showing local excavation of the surface, resulting from the sloughing of inflammatory necrotic tissue. It is the result of a variety of causes, e.g., denture irritation, aphthous stomatitis (STOMATITIS, APHTHOUS); NOMA; necrotizing gingivitis (GINGIVITIS, NECROTIZING ULCERATIVE); TOOTHBRUSHING; and various irritants. (From Jablonski, Dictionary of Dentistry, 1992, p842)
Autoimmune diseases affecting multiple endocrine organs. Type I is characterized by childhood onset and chronic mucocutaneous candidiasis (CANDIDIASIS, CHRONIC MUCOCUTANEOUS), while type II exhibits any combination of adrenal insufficiency (ADDISON'S DISEASE), lymphocytic thyroiditis (THYROIDITIS, AUTOIMMUNE;), HYPOPARATHYROIDISM; and gonadal failure. In both types organ-specific ANTIBODIES against a variety of ENDOCRINE GLANDS have been detected. The type II syndrome differs from type I in that it is associated with HLA-A1 and B8 haplotypes, onset is usually in adulthood, and candidiasis is not present.
Conditions characterized by loss or dysfunction of myelin (see MYELIN SHEATH) in the brain, spinal cord, or optic nerves secondary to autoimmune mediated processes. This may take the form of a humoral or cellular immune response directed toward myelin or OLIGODENDROGLIA associated autoantigens.
