Axial Spondyloarthritis: Clinical Characteristics, Epidemiology, and General Approaches to Management

Abstract

Axial spondyloarthritis (axSpA) is a chronic inflammatory condition, with an age of onset almost exclusively under 45 years. Although symptoms are initially centred on the sacroiliac joints and spine, extraspinal manifestations are common and add considerably to the burden of disease. In this narrative review, the authors provide an update on the epidemiology of the disease and briefly summarise the pathophysiology. The authors detail the clinical manifestations of axSpA, including an overview of axial features, peripheral manifestations, and associated comorbidities. The authors outline the current outcome measures used in the assessment of patients. Finally, the authors provide a summary of the general principles of treatment and briefly outline the role of patient education in the management of individuals with axSpA.
