IPA identified IL17R as an upstream regulator for the PsA skin versus normal skin gene set, but not for the PsA synovium versus normal synovium gene set.
Other studies established that PDGF is a survival factor for these PSA-NCAM+ pre-progenitors (Grinspan and Franceschini, 1995; Ben-Hur et al., 1998).
For low PSAs, trigger PSA remains most relevant.

Figure 1: Regional association plots for chromosome 5q31 for PsA (cases=1,962, controls=8,923) and psoriasis (cases=1,784, controls=5,175).
Soluble biomarkers represent an ideal means for screening patients for PsA.
Sensitivity for detection of recurrence was 95.7 % for PSA-values ≥ 2ng/ml, 81.4 % for PSA-values of 1-2 ng/ml, 76% for PSA-values 0.5-1 ng/ml, and 51% for PSA values ≤ 0.5 ng/ml.
A number of traditional treatments used to manage psoriasis, such as methotrexate and cyclosporine, are also effective for PsA, but these agents are often inadequately effective, temporary in benefit and associated with significant safety concerns.
These descriptive findings could have implications regarding comparative effectiveness research for tests and treatments for PsA and SSc.
As expected, the highest degree of analogy to clinical trials was found for RA, the lowest for PsA.
Therefore, the provisional choice was to develop at least two documents, one for axSpA and one for PsA.
