Studies of serum copper and caeruloplasmin were performed in patients with ankylosing spondylitis, systemic sclerosis, and morphea. Mean levels of both were raised significantly in ankylosing spondylitis, with the greatest increases in the worst cases. In patients with systemic sclerosis there was a significant increase in the mean level of caeruloplasmin, but not of copper, although both were raised in the 2 patients with the most aggressive disease. No alterations were found in patients with morphea. The values in the patients overlapped considerably with the values in the control subjects. It is thought that the increase in serum copper is probably secondary to the increase in caeruloplasmin which occurs as a nonspecific response to inflammation.

Autoantibodies to CRP were reported previously in patients suffering from toxic oil syndrome. This syndrome resembles autoimmune diseases such as systemic lupus erythematosus (SLE) or systemic scleroderma. We therefore examined the prevalence of antibodies to CRP and other acute-phase proteins in autoimmune diseases, including SLE, subacute cutaneous lupus erythematosus (SCLE), systemic scleroderma (SSc), and primary biliary cirrhosis (PBC), as well as in bone marrow transplantation-induced chronic graft-versus-host disease and eosinophilia-myalgia syndrome. IgG antibodies to CRP were found in 78% of SLE and in 30% of SCLE patients, while 16% of patients with PBC were positive. In up to 45% of patients with SSc predominantly IgG antibodies to ceruloplasmin were detectable. Lack of systemic involvement as in discoid lupus erythematosus and localized scleroderma (morphea) correlated with low or absent antibody formation. However, no correlation was found between anti-acute-phase protein antibodies with liver disease or other organ involvement. Adsorption studies revealed that non-native epitopes on the CRP molecule, termed modified CRP, are the main target of antibodies. Chronic inflammatory tissue injury in systemic autoimmune disease might increase the presentation of cryptic epitopes of CRP to the threshold required for T cell activation.
