Axial spondylitis is a chronic inflammatory disease primarily affecting the axial skeleton but can also involve peripheral joints. Axial spondylitis is often associated with extra-articular manifestations, such as inflammatory bowel diseases, emphasizing the need for rigorous monitoring and personalized therapeutic approaches.

This study analyzes the prevalence and characteristics of inflammatory bowel diseases in patients with axial spondylitis
