Abstract

Objectives. In this study, we assessed the extra-articular symptoms in constellation with selected serum cytokines and disease activity in spondyloarthritis (SpA). Patients and Methods. We studied 287 SpA patients: 131 had AS, 110 had PsA, and 46 had SAPHO. We assessed extra-articular symptoms in all cases. In 191 SpA patients, we measured serum interleukin-6 (IL-6), interleukin-18 (IL-18), interleukin-23 (IL-23), endothelin-1 (ET-1), vascular endothelial growth factor (VEGF), and epidermal growth factor (EGF). Results. Patients with acute anterior uveitis (AAU) had higher VAS (), BADSDAI (), ASDAS-ESR (), CRP (), IL-6 (), and IL-18 () levels. Patients with inflammatory bowel disease (IBD) had higher VAS (), CRP (), and IL-6 () levels. Patients with skin psoriasis had lower VAS () and BASDAI () levels. Patients with psoriatic onycholysis had lower VAS (), BASDAI (), and CRP () and higher IL-23 () levels. Patients with PPP had lower BASDAI () and higher ET-1 () levels. Conclusions. SpA patients with increased serum IL-18 and decreased serum ET-1 had an increased risk of extra-articular symptoms. In SpA patients, increased disease activity was associated with an increased risk of AAU and IBD and a decreased risk of skin psoriasis, psoriatic onycholysis, and PPP.
