Anti-TNFs in axial spondyloarthritis.

Since there is no evidence regarding the efficacy of conventional synthetic disease modifying anti-rheumatic drugs in the improvement of axial spondyloarthritis (SpA), anti-tumor necrosis factors (anti-TNFs) are recommended if nonsteroidal anti-inflammatory drugs fail, or in case of high disease activity. Anti-TNFs show encouraging data regarding pain reduction, improved mobility and quality of life in both ankylosing spondylitis and non-radiographic axial spondyloarthritis. However, withdrawal of anti-TNF therapy leads to relapse of disease activity in SpA. Moreover, osteoproliferation does not seem to be influenced by anti-TNFs.
