All were tested for anti-HBc as well as for HBsAg and HBV-DNA if anti-HBc positive. <h3>Results</h3> Among the 540 patients, anti-HBc was detected in 101/540 (19%). HBsAg was positive in 8/540 (1.5%) with a positive HBV-DNA in 2 patients (330 and 9.092 UI/ml, respectively), not detected in 4 and not available in the other two. Prevalence of anti-HBc was significantly higher in males 37/146 <i>vs</i> 64/394 in females; p=0.018. Non-Italians showed higher prevalence of anti-HBc compared to Italians (23/99 <i>vs</i> 76/441 respectively, p=0.202). 16/101 (16%) anti-HBc-positive patients have received biological treatment (alone or in association with disease-modifying antirheumatic drugs) ± steroids for an average of 7.5 years but none developed HBV reactivation. The prevalence of anti-HBc in different rheumatic diseases is analyzed in the table 1. <h3>Conclusions</h3> About one fifth of rheumatic patients are anti-HBc positive which showed higher prevalence in males. Screening for a resolved or active HBV infection is mandatory for all patients with rheumatic diseases especially if candidates for an immunosuppressive therapy. The potential risk of HBV reactivation in such setting is low. <h3>Disclosure of Interest</h3> : None declared <h3>DOI</h3> 10.1136/annrheumdis-2014-eular.5467Read More
