BackgroundPain represents one of the main clinical symptoms of Rheumatoid Arthritis (RA) being used as an indicator of disease activity. However, many RA patients reports clinically significant levels of pain even in the periods of remission. Recent studies [1] revealed that biological treatments are inequal in terms of how they manage inflammation and pain. The concept of Post-Remission Syndrome was defined in the context presence of residual pain in RA patients that are in clinical remission but still present clinical symptoms that impairs their quality of life [2]; the syndrome might be a reason for decreased work productivity [3,4]. Apart of the nociceptive pain previous works identified neuropathic and nociplastic pain in the composition of residual pain. In order to better understand and manage this situation is paramount important to identify and explain the exact nature of pain present during and after the periods of activity in RA.ObjectivesThe present study intended to explore the quality of pain assessment and management in subjects with RA in a major tertiary clinic.MethodsIn a major tertiary clinic of rheumatology consecutive subjects with RA have been questioned about the history, evolution and management of their disease; separately the level of nociceptive, neuropathic and nociplastic (fibromyalgic) pain was evaluated by using validated instruments. For a better understanding of the differences, we included and compared subjects with osteoarthritis and other inflammatory rheumatic diseases.Results43 subjects have been evaluated in a 6 months interval with a 2:1 F:M ratio; 22 of them received biological therapy (8 different molecules have been identified). Although 32 subjects did not present any sign of inflammation 21 of them declared significant level of pain (VAS>4), 12 have identified with neuropathic pain and 11 with nociplastic pain. Both in case of neuropathic and nociplastic pain groups less than 50% have been previously actively evaluated for non-nociceptive pain. Non-nociceptive pain was poorly treated and prolonged anti-nociceptive pain treatment was used despite evident lack of effect. The variable ability of pain reduction of biological DMARDs has not been previously discussed with any subject; the subject of residual pain was also poorly covered during biological drug selection.ConclusionNon-nociceptive pain has the potential to be considered a major reason of residual pain in RA and non-RA subjects. Rheumatologists seems to be captured in the paradigm of nociplastic = inflammatory pain with little interest in other types of pain that results in suboptimal diagnostic and management of pain.References[1]Taylor PC, Lee YC, Fleischmann R, Takeuchi T, Perkins EL, Fautrel B, Zhu B, Quebe AK, Gaich CL, Zhang X, Dickson CL, Schlichting DE, Patel H, Durand F, Emery P.
