How it begins
Heterogeneous group of systemic autoimmune diseases that predominantly affect skeletal muscle. Comprehensive analysis of the contemporary classification, pathophysiology, autoantibody profile, clinical manifestations, EULAR/ACR 2017 diagnostic criteria and evidence-based therapeutic strategy.
