Background: Autoantibodies directed against complement C1q (anti-C1q) have been described in a number of systemic autoimmune disorders. In systemic lupus erythematosus, they are strongly associated with proliferative lupus nephritis. However, no study has focused on the presence of anti-C1q in organ specific autoimmune disorders. The aim of this study was to determine the prevalence of anti-C1q in autoimmune thyroid disorders (AITD).Methods: Serum levels...
