Abstract :

Availability of biologics, particularly tumor necrosis factor alpha (TNF-�?±) inhibitors, has revolutionized the treatment of spondyloarthritis (SpA). The main side effect associated with TNF-�?± inhibitors is increased rate of infection. Despite significant concerns about tolerability and adverse events of TNF-�?± inhibitors in treatment of SpA, they have stood the test of time with acceptable safety outcomes. However, there is a subset of patients with psoriatic arthritis (PsA) and ankylosing spondylitis (AS) who fail to respond to TNF-�?± inhibitors, lose efficacy over a period of time, or develop serious adverse events, particularly opportunistic infections. Newer therapeutic options have become available for these patients including interleukin-17 (IL-17) axis antagonists. Their safety data is limited to clinical trials only, with no registry data available as yet. There are no large head-to-head comparative trials between TNF-�?± inhibitors and IL-17 axis inhibitors. Based on data from clinical trials of relatively limited duration, infection rates are quite similar between these two classes of biologics but there are, as yet, no reports of reactivation of opportunistic infections like tuberculosis with IL-17 axis antagonists. However, pre-screening for tuberculosis and prophylaxis in appropriate candidates is still needed. The current available data have shown no other major discrepancies in the adverse events between TNF-�?± inhibitors and IL-17 axis inhibitors. More data is needed to effectively determine the comparative safety of TNF-�?± inhibitors versus IL-17 axis antagonists.
