Old and new treatment targets in axial spondyloarthritis

Two main treatment targets in axial spondyloarthritis (axSpA) could be currently defined: (1) reduction of inflammation resulting in control of signs and symptoms such as pain and stiffness and (2) prevention or retardation of structural damage progression in the spine resulting in preservation of functional status and improvement in the long-term outcome. A good control of signs and symptoms could be successfully achieved nowadays in the majority of patients treated with non-steroidal anti-inflammatory drugs (NSAIDs-the first-line therapy in axSpA) and with tumour necrosis factor (TNF) α blockers (the second-line therapy, if NSAIDs fail). Several pipeline drugs including interleukin (IL) 17 and IL-23 antagonists might be helpful in the immediate future in achievement of this treatment target in case of inefficacy of NSAIDs and TNFα blockers. Retardation of radiographical spinal progression in axSpA-disease modification-is currently a much more challenging task than a good symptom control. In this review, we discuss symptomatic and possible disease-modifying properties of current and forthcoming treatment options for axSpA.
