The Use of TNF-α Inhibitors in Active Ankylosing Spondylitis Treatment

Ankylosing spondylitis (AS) is a challenging disease, characterized by chronic inflammation and structural damage primarily affecting the axial skeleton, while extra-articular manifestations may also appear. This results in the deterioration of patients' quality of life. Over the past few decades, tumor necrosis factor-α (TNF-α) inhibitors have revolutionized the management of AS, offering substantial relief from symptoms and improving patient outcomes. The aim of this review is to assess the efficacy of TNF-α inhibitors in patients with active AS. A search was performed in the PubMed database using the following keywords: ("TNF alpha inhibitors" OR "anti TNF-a" OR "TNF-a inhibitors" OR "anti TNF-alpha" OR "Etanercept " OR "Golimumab" OR "Infliximab" OR "Certolizumab pegol" OR "Adalimumab") AND "ankylosing spondylitis". The search was completed in February 2024, and 35 studies were included in this review following PRISMA guidelines. The findings reveal evidence supporting the efficacy of TNF-α inhibitors in reducing inflammation, preventing structural damage, and enhancing overall well-being in AS patients. Overall, TNF-α inhibitors have emerged as a cornerstone in the therapeutic algorithm against AS with a very satisfactory safety profile.
