A case of long-standing classical rheumatoid arthritis complicated by serological and clinical characteristics of SLE

Scand J Rheumatol. 1993;22(3):138-40. doi: 10.3109/03009749309099259.

Abstract

A patient with RA who developed anti-Sm antibodies, a false positive serological test for syphilis (FPSTS), pericardial effusion, and leukopenia, 19-year after the onset of classical RA, is described. This case indicates a possible clinical association between the development of specific autoantibodies and clinical symptoms of SLE.
