This study states that The assessment of multifaceted disease processes is a key element in the management of chronic inflammatory rheumatic diseases such as axial spondyloarthritis (axSpA), including ankylosing spondylitis (AS). The evaluation includes not only patients’ history and clinical symptoms but also the assessment of disease activity, function, structural damage, and comorbidities. The management of patients with axSpA is especially challenging in this regard, because this complex disease entity has a wide variability of clinical signs and symptoms1,2. Within the variable course of SpA, adding to the burden of the disease are axial involvement, peripheral arthritis, enthesitis, and extramusculoskeletal involvement in other organs such as the eye, the skin, and the gut. The most prominent health problems in addition to inflammatory back pain are spinal stiffness, mobility limitations, fatigue, and sleep problems that are associated with significant restrictions in activities of daily living in patients with axSpA3.

The evaluation of the current state of health of a patient with axSpA includes the assessment of several aspects of the disease with a focus on disease activity, because the degree of inflammatory activity is the main driver of pain, stiffness, and radiographic progression.
