[News in the treatment of axial spondyloarthritis].

Axial spondyloarthritis is a rheumatic disease characterized by inflammation and bone formation causing impaired function of the spine and affected joints. Basic research has highlighted the key role of dysregulation of tumor necrosis factor α, interleukin- 23 and interleukin-17 cytokine production in the etiology of axial spondyloarthritis. Tumor necrosis factor α and interleukin-17 inhibitors have been shown to be effective in clinical trials and are currently approved biological disease-modifying drugs for all disease subgroups.
