The aims of this study were to examine levels of the crosslinking components of collagen, pyridinoline (Pyr) and deoxypyridinoline (D-Pyr) which are bone resorption markers, in patients with rheumatoid arthritis (RA), and to determine their association with disease activity and bone mineral density (BMD). These bone resorption markers were measured in 35 postmenopausal women with RA, 30 age-matched female patients with osteoarthritis of the knee (controls), and 47 patients with bone fracture. The mean BMD in the RA patients was lower than that in the control group, and the Z-score (number of standard deviations above and below the normal mean after comparison with age and sex matched normal control values) was significantly lower. Mean levels of Pyr and D-Pyr were significantly higher in the RA patients than in the control group, and the Pyr/D-Pyr ratio was also higher in the RA patients than in the other groups. Regarding the relationship between the bone resorption markers and RA activity, Pyr increased as the Lansbury's joint score (number of swollen joints corrected for joint size according Lansbury) rose, showing a normal correlation; D-Pyr also showed a normal correlation. Pyr and D-Pyr were high in patients with a high erythrocyte sedimentation rate, showing a normal correlation. Only Pyr increased with increases in C-reactive protein (CRP), showing a normal correlation. These findings suggested that a high value for Pyr (which includes a large amount of collagen type II) indicated that RA activity was affected more by synovitis, rather than by systemic osteoporosis.
