Anti-Ku antibodies have been reported in a wide spectrum of autoimmune diseases, sometimes in association with inflammatory myopathies (IM). We studied the clinical, laboratory, and muscle histologic features of all anti-Ku-positive patients detected in our hospital during the last 10 years, as well as their treatment and outcomes. Anti-Ku antibodies remain rarely detected, but their presence can be frequently associated with corticosensitive IM and severe, corticoresistant ILD. |
