The idiopathic inflammatory myopathies (IIM) are systemic connective tissue diseases which are characterized by symmetrical, proximal muscle weakness, decreased muscle endurance and chronic inflammation in muscle tissue [13]. They can be subclassified into dermatomyositis, polymyositis and inclusion body myositis (IBM) according to differences in clinical as well as histopathological features [1, 4]. Dermatomyositis may occur in both adults and children; in this review, we will, however, focus on the treatment of adult forms of myositis only. Myositis may exist as a disease entity on its own or may be linked to another inflammatory connective tissue disease such as systemic sclerosis or mixed connective tissue disease. Myositis may also be associated with a malignancy, this is particularly true for dermatomyositis, but the association with polymyositis is more controversial [1]. The IIM are chronic disorders in most cases and up to two-thirds of
