RT Journal Article SR Electronic A1 Rizzo, Toni T1 Inflammation and Fatty Degeneration in New Bone Formation in Patients with AS Treated with Anti-TNF Agents JF MD Conference Express YR 2012 FD SAGE Publications VO 12 IS 9 SP 19 OP 20 DO 10.1177/155989771209017 UL http://mdc.sagepub.com/content/12/9/19.abstract AB When the inflammation of ankylosing spondylitis (AS) subsides, it may be replaced by repair tissue and fatty lesions, a process that leads to osteoproliferation and development of syndesmophytes. This article presents results from the European Ankylosing Spondylitis Infliximab Cohort [EASIC] study, an open-label extension of the Ankylosing Spondylitis Study for the Evaluation of Recombinant Infliximab Therapy [ASSERT]. The objective of the EASIC study was to directly compare the effect of inflammation and fatty degeneration on the development of syndesmophytes in patients with AS after 5 years of anti-TNF therapy.
