Key clinical point: A substantial proportion of patients with early rheumatoid arthritis (RA) had unacceptably high levels of pain with or without low inflammation at 2 years after diagnosis, with joint tenderness at the 3-month follow-up predicting long-term pain despite low inflammation.
Major finding: Nearly one third of patients with early RA had unacceptable pain levels after 2 years of follow-up, with almost 80% of them also having low inflammation. At the 3-month follow-up, the difference between tender and swollen joint counts predicted the 2-year risk for unacceptable pain (odds ratio [OR] 2.00; P < .05) and unacceptable pain with low inflammation (OR 2.02; P < .05).
Study details: Findings are from a retrospective study including 275 patients with early RA.
