Peripheral and central contributions to persistent pain in rheumatoid arthritis: an unbiased latent profile analysis identifies four mechanism-based phenotypes

2026-06-26

Abstract excerpt

<h4>Background</h4> Pain frequently persists in rheumatoid arthritis (RA), despite effective control of inflammation. The mechanisms driving this residual pain remain poorly characterised in individual patients. <h4>Methods</h4> In 172 patients with established RA and clinically relevant pain (mean NRS 6.5/10) and 80 pain-free controls, we combined indicators of inflammatory disease (CRP, joint counts, power Dop...
