Abstract
The efficacy of subcutaneous immunoglobulin is reported in several neurological disorders and, more recently, its use has been extended to other inflammatory diseases, such as the idiopathic inflammatory myopathies, including polymyositis and dermatomyositis. Due to the rarity of these disorders, the role of immunoglobulin, administered intravenously or subcutaneously, remains unclear and poorly investigated. We report our experience about the use of subcutaneous immunoglobulin in myositis spectrum disorders, from idiopathic inflammatory myopathies to more complex conditions, such as overlap and cancer-associated myositis or pregnancy.
