Autoantibodies to extractable nuclear antigens (ENAs) pattern in rheumatoid arthritis patients: Relevance and clinical implications

“…34 Atypical features may include hand calcinosis and/or absent myositis. 35,36 In previous studies was shown that ACPA-positive ASS patients may show overlapping features of RA-ASS and may develop refractory erosive arthritis. 5,36 Only a few case reports describe ASS complicating the course of RA.…”

“…35,36 In previous studies was shown that ACPA-positive ASS patients may show overlapping features of RA-ASS and may develop refractory erosive arthritis. 5,36 Only a few case reports describe ASS complicating the course of RA. [5][6][7][8][9][10][11] In general, there is little justification for requesting tests for anti-ENA autoantibodies unless the ANA test is positive.…”
