Correlation between anti-DNA antibody titre and psychiatric manifestations in systemic lupus erythematosus

Abstract

A patient with systemic lupus erythematosus with predominant psychiatric involvement was followed during two psychotic exacerbations of her disease. A high correlation was found between disease activity and the titre of anti-DNA antibodies. Disease activity was preceded and accompanied by a high titre, while remission was associated with a low titre. The significance of this correlation for the pathogenesis, diagnosis and management of the psychiatric symptoms of systemic lupus erythematosus are discussed.
