An ultrasonographic insight into musculoskeletal manifestation in 100 systemic lupus erythematosus patients.

In conclusion: 1. joint involvement in SLE is frequent and underacknowledged; 2. the overall inflammatory burden is associated with systemic disease activity and joint damage; (3) destructive arthritis is more likely to occur in the context of concomitant RA or within an "RA-like" subtype of SLE arthropathy; 4. hand dominance is associated with synovitis, but not structural changes; 5. US assessment may help tailor the management of joint involvement, thus preventing joint damage and disability in SLE patients.
