title: Correlation of antibodies to ribosomal P protein with psychosis in patients with systemic lupus erythematosus.
abstract: Ninety one Japanese patients with systemic lupus erythematosus (SLE) were studied to determine the clinical significance of antibodies to ribosomal P protein (anti-P). Anti-P was detected by western blotting in 38 of 91 patients (42%). Clinical symptoms of SLE were compared between patients with and without anti-P. The occurrence of lupus psychosis was significantly higher in patients with anti-P than in those without anti-P (9/38 v 1/53). No significant association was found between anti-P and other symptoms of SLE. These data strongly support the suggestion proposed by previous workers that anti-P is a marker autoantibody for the development of lupus psychosis.
