Polymyositis and the associated inflammatory myopathies have an associated increased risk of cancer. [3] The features they found associated with an increased risk of cancer were older age, age greater than 45, male sex, difficulty swallowing, death of skin cells, cutaneous vasculitis, rapid onset of myositis (<4 weeks), elevated creatine kinase, higher erythrocyte sedimentation rate and higher ...
There have been few randomized treatment trials, due to the relative rarity of inflammatory myopathies. [4] The goal of treatment is improvement in activities of daily living and muscle strength. Suppression of immune system activity (immunosuppression) is the treatment strategy. Patients with PM or DM almost always improve to some degree in ...
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 ...
Polymyositis is an autoimmune disease that causes inflammation and weakness of the skeletal muscles responsible for movement. Dermatomyositis is a form of polymyositis that is associated with skin rash, in addition to muscle inflammation. Both disorders can significantly compromise quality of life and are very challenging to treat.
Polymyositis that does not respond to treatment is likely IBM. [35] Dermatomyositis shares a number of similar physical symptoms and histopathological traits as polymyositis, but exhibits a skin rash not seen in polymyositis or sIBM. It may have different root causes unrelated to either polymyositis or sIBM. [36]
Complications: Calcinosis, lung inflammation, heart disease [1] [2] Usual onset: 40s to 50s [3] Duration: Long term [1] Causes: Unknown [1] Diagnostic method: Based on symptoms, blood tests, electromyography, muscle biopsies [3] Differential diagnosis: Polymyositis, inclusion body myositis, scleroderma [3] Treatment
Polymyositis produces muscle weakness. It can often be treated by drugs like corticosteroids or immunosuppressants. Inclusion body myositis is a slowly progressive disease that produces weakness of hand grip and straightening of the knees. No effective treatment is known. (M60.9) Benign acute childhood myositis (M61) Myositis ossificans
Scleromyositis, is an autoimmune disease (a disease in which the immune system attacks the body). People with scleromyositis have symptoms of both systemic scleroderma and either polymyositis or dermatomyositis, and is therefore considered an overlap syndrome.
