Goodbye to the term ‘ankylosing spondylitis’, hello ‘axial spondyloarthritis’: time to embrace the ASAS-defined nomenclature

Axial spondyloarthritis (axSpA) is the overall term for the disease; a further differentiation, of which radiographic vs non-radiographic is only one aspect, may be relevant for research purposes

Ankylosing spondylitis (AS) and r-axSpA can be used interchangeably, but the preferred term is r-axSpA

Proposal to officially change the meaning of the ASDAS acronym to 'Axial Spondyloarthritis Disease Activity Score'

The term ASDAS (instead of ASDAS-CRP) should be preferred and applied to the ASDAS calculated with CRP
