So for peripheral SpA, here are the diagnosis guidelines:
the ASAS criteria for peripheral SpA are to be applied in patients with either peripheral arthritis (usually asymmetric arthritis and predominantly involving the lower limb), or enthesitis or dactylitis.
In addition, at least one feature of uveitis, HLA-B27, preceding genitourinary or gastrointestinal infection, psoriasis, inflammatory bowel disease, sacroiliitis on imaging (radiographs or MRI) must be present, or, at least two features of arthritis, enthesitis, dactylitis, IBP, positive family history for SpA.
