OBJECTIVE: This study aimed to investigate the effects of central sensitization (CS) on pain sensitivity, disease activity, neuropathic symptoms and quality of life (QoL) in patients with rheumatoid arthritis (RA).
METHODS: Sixty patients diagnosed with RA according to the American College of Rheumatology and the European League Against Rheumatism (ACR/EULAR) 2010 classification criteria were included in the study. Patient assessment tools included visual analog scale (VAS) for pain, algometer for pain pressure threshold (PPT), disease activity score in 28 joints (DAS-28) for disease activity (DA), central sensitization inventory (CSI) for CS and rheumatoid arthritis QoL questionnaire for QoL.
RESULTS: Central sensitization was identified in 29 (48.3%) patients. Although erythrocyte sedimentation rate (ESR), C-reactive protein and swollen joint count were comparable between patients with or without CS, higher VAS, tender joint count and DAS-28 scores were observed in patients with CS (all p<0.05). Pain pressure thresholds (PPT) at the wrist (PPTW) and the trapezius muscle (PPTT) were lower in patients with CS (p=0.004, p=0.001, respectively). It was found that neuropathic pain components increased and quality of life decreased as CSI scores increased (all p=0.000).
CONCLUSION: The presence of CS leads to pain sensitivity as well as overestimation of disease activity in RA patients. The presence of CS should not be overlooked in RA patients to avoid overtreatment for inflammation and to determine the treatment need for nociplastic pain.
