Pruritus in adult dermatomyositis.

Dermatomyositis has a significant clinical component of pruritus that has not yet been studied. Pruritus can significantly affect the life of patients. The aim of the present work was to study the degree of pruritus experienced by patients. A four-question survey was sent to patients with documented dermatomyositis. The survey used a 100-mm Visual Analogue Scale (VAS) to describe current, worst and daily pruritus, and the effect this has on daily activities. Twenty-six subjects returned completed questionnaires: four had no pruritus; the majority had a significant amount with means above 50 on the VAS. A mean of 44.6 was found for the effect on daily life. Further studies should be performed to examine the prevalence and severity of pruritus in this population and it's effect on their quality of life. Clinicians must be aware of the significant pruritus and provide adequate therapy to improve quality of life.
