Purpose of review

The review gives an updated overview of some of the new concepts in the management of psoriatic arthritis (PsA): early diagnosis, remission as an objective, treat-to-target, and treatment guidelines.

Recent findings

Early diagnosis, targeting remission as part of a treatment strategy, and new guidelines providing evidence-based support to these concepts are main topics in recent publications.


Dermatologists and rheumatologists should work together to reduce the number of patients remaining undiagnosed, and the time to do so.


Remission definition in PsA is still controversial. There is good evidence and convincing arguments for both multidimensional measures, such as minimal disease activity, or unidimensional ones, as disease activity index for PsA. New data on the analysis of tight control of inflammation in early PsA trial showed that the strategy might not be cost-effective on the short term, and that oligoarthritis is less benefited.


The new European League Against Rheumatism and Group for Research and Assessment of Psoriasis and PsA recommendations exhibit differences. Methotrexate and tumor necrosis factor inhibitors are favored in European League Against Rheumatism guidelines, whereas other conventional synthetic disease-modifying antirheumatic drugs and biologics are equally positioned in Group for Research and Assessment of Psoriasis and PsA recommendations.
