ReviewClinical presentation of the idiopathic inflammatory myopathies.
The hallmark of the inflammatory myopathies is muscle weakness. Although this feature can lead to significant disability and impairment of activities of daily living, its initial presentation may not be recognized early. Older individuals, in particular, may feel that the changes caused by myositis reflect the effects of aging rather than those of a disease process, and diagnosis, therefore, may be delayed. ⋯ This is particularly true for the pulmonary, GI, and cardiac manifestations and when cancer is associated with myositis. For these reasons, such features of IIM should be carefully evaluated, treated, and monitored over the course of the illness; in some cases these may play a greater role in determining the outcome of patients with IIM than the muscle involvement itself. It is hoped that in the future increased familiarity with the manifestations of the inflammatory myopathies, together with a better understanding of the underlying pathogenesis, will lead to more rapid diagnosis and more effective treatments.
