Early recognition of axial spondyloarthritis: imaging and genetic aspects

Abstract

The studies described in this thesis were all centred around the same aim: the early recognition

of axial spondyloarthritis (axSpA) and a minimization of the diagnostic delay. An important

step in tackling these issues was that experts in the field have designed prospective cohort

studies in which consecutive patients with either chronic or inflammatory back pain (the latter being the most common first symptom) of short duration are included and followed up in a standardized manner with imaging performed at certain pre-set times. This allows us to obtain information on who will develop axSpA and who will not. Those cohort studies provide valuable information on the early detection and disease course of axSpA and form the basis of the research presented in this thesis.
