Abstract
Recent proposals for re-classification of spondyloarthropathies according to the predominance of peripheral and axial manifestations and for non-radiographic ankylosing spondylitis to be re-named axial spondyloarthritis are reviewed. It is argued that such proposals are less likely to advance knowledge in the study of spondyloarthopathies and that accurate classification criteria for defined diseases, for example psoriatic arthritis, remain as necessary now as they ever did. The CASPAR criteria remain the best performing classification criteria for psoriatic arthritis.

This study proposes new classification criteria for SpA that have peripheral manifestations and potentially re-defines several diseases that fall under the SpA umbrella. Classification criteria that identify SpA in general are also defined by merging criteria for axial and peripheral SpA.

Arthritis Care Res (Hoboken). 2012. Published online 25 July 2012. doi:10.1002/acr.21804. Application of the axSpA criteria arm that uses HLA-B27 to identify patients leads to a high population prevalence of SpA. The prevalence of axSpA defined by HLA-B27 was 0.09% compared to a prevalence of 0.04% of radiographic axSpA.

Ann Rheum Dis. 2012; published online October 25, 2012. doi: 10.1136/annrheumdis-2012-202073. This paper reviews evidence that SpA with axial symptoms are far more heterogeneous than ankylosing spondylitis and suggests that it is premature to consider axSpA as the same disease as ankylosing spondylitis.

Performance of classification criteria for peripheral spondyloarthritis and psoriatic arthritis in the Leiden early arthritis cohort. Ann Rheum Dis. 2012;71(8):1366–9. This useful study of early arthritis was able to clearly show that the CASPAR criteria for classifying psoriatic arthritis was more accurate than the new ASAS pSpA criteria and that all SpA criteria (ASAS, Amor, ESSG) have less than desirable sensitivity for classifying SpA in early disease.
