Reducing the risk of psoriatic arthritis

[Waine]

There is another quirk in the start. It is assumed that every PsA patient also has Psoriasis, which is not true for about 10% of the PsA population.
And…. Mild systemic agents?  What are those? Topicals do not work for PsA, so perhaps they mean MTX?? But that is by long NOT MILD….. not to speak of Acetretin or Cyclosporin, they are worse than MTX.
The only thing that could be seen as mild is DMF, but that is hardly used outside of the Netherlands and Germany.

I think they're saying this study changed the nature of people studied excluded patients with PsD treated with Mild or Topic treatments, and instead used those who had received Phototherapy. I have no idea what a "Mild Systemic agent" might be, none that I ever had were mild, but then I was only ever treated for PsA and never for PsD. My PsD was low enough that over the counter therapeutic shampoos and ointments were sufficient. My PsA not!
