Anti-C1q autoantibodies can be identified across a broad spectrum of autoimmune diseases, with a particular emphasis on their heightened sensitivity in diagnosing hypocomplementemic urticarial vasculitis.
In systemic lupus erythematosus (SLE), the presence of anti-C1q antibodies is notably linked to proliferative lupus nephritis, and their absence demonstrates a negative predictive value for the development of lupus nephritis, approaching close to 100%.
