The development of necrotizing myopathy after statin exposure is insufficient to make the diagnosis. Testing must first exclude other causes of myositis and necrotizing myopathy. [7] A muscle biopsy consistent with SAAM will demonstrate muscle cell death with muscle fiber regeneration and typically has few inflammatory cells.
For myositis, which is caused by a viral infection, no treatment is typically needed. [4] For myositis caused by a bacterial infection, antibiotics can be used. [4] For myositis caused by a medication, it is important to stop using that medication. [4] There are a variety of treatment options available if myositis is caused by an autoimmune ...
overlapping symptoms (such as muscle weakness, pain, elevated CK); that delaying treatment for an inflammatory myopathy, in order to exclude potential non-inflammatory myopathies, may cause irreversible damage (although administering immunosuppressants and glucocorticosteroids to non-inflammatory myopathies may also cause damage);
Because different types of myopathies are caused by many different pathways, there is no single treatment for myopathy. Treatments range from treatment of the symptoms to very specific cause-targeting treatments. Drug therapy, physical therapy, bracing for support, surgery, and massage are all current treatments for a variety of myopathies.
[1] [2] [3] It was originally identified and recorded in the 1960s in pure breed pugs, with which this disease is nowadays mostly associated with, occurring essentially in small breed dogs ranging from six months to seven years of age. [4] [2] [5] It causes intense necrotizing inflammatory lesions in the brain stem and Cerebellum. [3]
Infections which are in the deep tissues (necrotizing cellulitis, fasciitis and myositis) often include Clostridium spp., S. pyogenes or polymicrobic combinations of both aerobic and anaerobic bacteria. Gas in the tissues and putrid-like pus with a gray thin quality are often found in these infections, and they are frequently associated with a ...
Symptoms tend to worsen with muscle exercise, and often continue after a patient is removed from statin therapy. [1] Common types of myopathy due to statins include myalgia, myositis, and rhabdomyolysis. Statins induce myopathy by inhibiting protein synthesis within the muscle. [6]
Immunosuppressive medications such as mycophenolate mofetil, azathioprine, and tacrolimus are often used alongside corticosteroids to manage myositis and other pulmonary symptoms. [ 9 ] It is believed that the mortality rate for antisynthetase syndrome is significantly higher than that of the general population. [ 10 ]
