Autoantibodies against C-reactive protein: clinical associations in systemic lupus erythematosus and primary antiphospholipid syndrome.

Abstract

We confirmed the high prevalence of anti-CRP autoantibodies both in patients with SLE and in non-SLE and aPL-positive patients. We observed that the presence of these antibodies was associated with lupus nephritis and with clinical features of the APS in patients with lupus and non-lupus patients.
