SLE is suggested by the presence of:
Discoid lupus erythematosus
High anti-DNA titer
Central nervous system (CNS) abnormalities
SLE and RA both produce symptoms of joint pain and inflammation, as well as fatigue. Both are known to affect smaller joints, including those found in the fingers, wrists, and feet. SLE and RA are both recognized as producing symmetrical symptoms. Joint damage is rarely associated with SLE.
