Serum levels of cytokines including IL-1\u00df, IL-6, sIL-6R, OPG, and RANKL were measured using ELISA.

Radiographic damage indices (erosion, narrowing, and total scores) were negatively associated with serum sIL-6R and OPG levels in multivariable-adjusted regression analysis. Serum sIL-6R levels in patients without radiographic damage were higher than in those with damage (p = 0.006).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion.<\/jats:title>\n                    <jats:p>Radiographic damage in patients with chronic gouty arthritis was negatively associated with serum sIL-6R and OPG.
