Incidence of Tuberculosis Among Korean Patients with Ankylosing Spondylitis Who Are Taking Tumor Necrosis Factor Blockers

Abstract

The risk of TB was higher in the TNF blocker-naive AS cohort than it was in the general population. However, the risk of TB was not increased in the TNF blocker-exposed AS cohort compared with the TNF blocker-naive AS cohort. Among patients with AS, etanercept is associated with a lower risk of TB compared with monoclonal antibodies.
