Sarah,
I agree with you this is why they created the SpA diagnosis and then try and associate you with maybe Enteric ReA, or Ps or IBD SpA or just AS....
Prof Erbringer stated that AS was probably a ReA to klebsiella.....
As for the individual it's alot to do with genes combinatioons and also exasperating factors, infection, diagnosis time, in some even nsaids.
Some of the reasons to distinguish eg PsA has a mutilans which is very damaging, Reactive Arthritis draws anti-biotics early on, and IBD the drain eel....and IBD treatment.
