Enhanced type 1 interferon signature in axial spondyloarthritis patients unresponsive to secukinumab treatment

Pacheco et al. demonstrated that, compared with axSpA patients who respond to secukinumab,  patients who do not respond show increased IL-17A-producing cells and have a more pronounced type 1 IFN signature, indicating a larger inflammatory burden.

The study aimed to distinguish clinical and immune cellular profiles between secukinumab treatment responders and secukinumab nonresponders, to better predict treatment outcomes in axial spondyloarthritis.
