Established and new treatments of the idiopathic inflammatory myopathies: dermatomyositis and polymyositis

The aim of this article was to critically review and summarize the evidence on established and novel treatments for adult-onset DM and PM derived from randomized controlled trials (RCT). In the absence of evidence from such trials, data from open studies and case reports have been reported. Abstract data 2002 through 2006, American College of Rheumatology and 2002 through 2007 European League against Rheumatism have been included if relevant, if sufficient information could be extracted with regard to diagnosis ascertainment, treatment modalities, and outcome measures, and if the reported data had not been published as a full paper.
