Commentary: A rare co-occurrence of anti CCP-positive rheumatoid arthritis with sacroiliitis

Abstract

Dear editor, I have read the case report titled, ‘A rare co-occurrence of anti CCP-positive rheumatoid arthritis with sacroiliitis’ written by Haridas  et al. with great interest! 1 The authors have highlighted (though rare) the need to consider the involvement of sacroiliac joints (SIJs) in patients diagnosed with rheumatoid arthritis (RA), which can be considered as an atypical joint involvement of RA from their experience with this case. However, there certain clarifications are needed for the common readers, which I would like to highlight in this commentary.
