HSS Study Links Joint Fluid Proteins to Inflammation Levels in Rheumatoid Arthritis
  • Hospital for Special Surgery presented three studies on improving rheumatoid arthritis treatment selection at ACR Convergence 2026 in Orlando, Florida.
  • Synovial fluid findings suggest joint fluid could offer a less invasive alternative to tissue biopsies for assessing inflammation.
  • Fluid protein patterns distinguished high from low tissue inflammation, potentially supporting more personalized treatment decisions.
  • Higher fluid inflammation was associated with elevated blood inflammatory markers and subsequent medication changes, but did not correlate with patient-reported pain.
  • Ultrasound findings varied by joint location and disease stage, affecting how well scans reflected underlying tissue inflammation.
