OBJECTIVE: Chronic pain is an important part of the clinical picture in patients with RA and therefore the authors attempted to assess the relationship of pain of patients with RA to the inflammatory process, articular damage and to predict the variance of pain in relation to psychosocial, demographic factors and functional disability.

METHOD: Pain was examined using the Nottingham Health Profile (NHP), psychological health by means of the General Health Questionnaire (GHQ) and disability was assessed by the Health Assessment Questionnaire (HAQ).

RESULTS: The authors examined 160 patients with RA with a mean age of 48.34 +/- 12.13 years and persistence of the disease for 21.32 +/- 15.61 months. Pain was significantly related to clinical manifestations of inflammation and articular damage. The relationship between pain and laboratory manifestations of inflammation (CRP, FW) was not very close. The relationship between age and pain and between persistence of the disease and pain was not statistically significant. Pain correlated significantly with functional disability (HAQ) (r = -0.54) and the articular index (RAI) (r = 0.58). Pain did not correlate with manifestations of depression (r = -0.15), but correlated significantly with anxiety (r = -0.35) and social dysfunction (r = -0.36). Among the investigated parameters (demographic factors, GHQ and HAQ) the most marked variation of pain was caused by HAQ (32%), GHQ (8%). Almost unrelated were demographic parameters (0.6%) (age, persistence of disease, education lifestyle, and gender).
