What are the typical joint paterns and extra-articular features of IBD-associated arthritis compared to axSpA?
IBD-associated arthritis presents with distinct patterns that differ from typical axSpA, as listed in table 1.
Table 1: Comparison of joint paterns and extra-articular features in IBD-associated arthritis vs. axSpA
Feature | IBD-associated arthritis | axSpA |
Main joint pattern | Peripheral, asymmetric oligoarthritis | Axial (SI joints, spine), symmetric |
Joint distribution | Lower limbs (knees, ankles); sometimes upper limbs | Spine and SI joints; less often peripheral joints |
Erosiveness | Typically non-erosive | Can progress to new bone formation (ankylosis) |
Course with disease | Flares with bowel activity (peripheral); axial may not | Often independent of gut flares |
Enthesitis, dactylitis | Possible, less prominent | Enthesitis central; dactylitis less common |
Eye involvement | Uveitis | Uveitis |
