The treatment of polymyositis, dermatomyositis and inclusion body myositis

Idiopathic inflammatory myopathy is a group of diseases of unknown etiology and probably autoimmune pathogenesis. Treatment of the diseases is divided into following stages: initial phase, intermediate phase, and long-lasting therapy. Glicocorticoids and other immunosuppressive drugs (commonly azathioprine and methotrexate) are applied for management. It is important to evaluate activity of the disease, effectiveness of the treatment and occurrence of adverse reactions. Inclusion body myositis is resis­tant to glicocorticoid therapy.
