Axial Spondyloarthritis
Ankylosing spondylitis (AS) is a chronic inflammatory arthritis affecting mainly the sacroiliac joints and spine, resulting in pain, stiffness, and reduced movement. Over the past decade there have been major advances in many aspects of the disease, including a broadening of the disease description to axial spondyloarthritis (axSpA). While the many advances have transformed the lives of patients with axSpA, they have also increased complexity for non-specialists in this area. This handbook contains a timely update of the key developments and current state of play in axSpA. It is intended primarily for the many healthcare professionals who encounter patients with this condition, in both primary and secondary care settings. It will also be of interest to the wider medical and research community.The handbook is written by rheumatologists with active research programmes and clinical expertise in these conditions. The topics covered include: • the clinical features • extra-articular manifestations and complications • the impact on patients’ lives • the major advances in genetics and pathogenesis • imaging advances • classification criteria and diagnosis (and the important differences between these) • treatment advances (particularly TNF inhibitors and upcoming biologics)
