Anti-Ro52 was the most common serological marker in patients with IIM (35\/147, 23.8%) and co-occurred with anti-Jo1 (10\/18, 55.6%; p=0.02). The prevalence of anti-Ro52 reactivity was significantly more than anti-Ro60 reactivity in patients with IIM, systemic sclerosis, primary biliary cirrhosis, mixed essential cryoglobulinemia and pSS. The mean signal intensity of anti-Ro52 reactivity was significantly higher in pSS than SLE and associated with rheumatoid factor positivity. The mean signal intensity of anti-Ro52 correlated with anti-Ro60 and anti-La in pSS and SLE.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Monospecific anti-Ro52 reactivity is not disease specific but may be of importance in patients with IIM.
