Inflammatory Myopathies

The inflammatory myopathies are a group of disorders in which the body’s immune system attacks the muscle cells causing weakness and muscle aches in the arms and legs.  The weakness can sometimes be severe.  Dermatomyositis, polymyositis, cholesterol medication related myositis, and inclusion body myositis (IBM) are the most common forms.  Early diagnosis is important so that patients can fully regain their strength.  Diagnosis typically involves lab testing, electrodiagnostic studies (EMG), and often times a muscle biopsy.  Once the diagnosis is made, patients will work with their doctors to find the best treatment to suppress the immune system from continually attacking the muscles.  There is no treatment as of yet for IBM other than supportive treatment.
