Axial Spondyloarthritis is a timely addition to the Oxford Textbooks in Rheumatology series, providing a comprehensive reference to this rapidly evolving field. The conceptual framework of the disease has now evolved beyond ankylosing spondylitis to encompass a broader concept of axial inflammation. Earlier recognition has opened the door to earlier intervention, and the understanding of the biologic basis of axial SpA has seen significant advances in recent years. The first textbook to cover axial spondyloarthritis in this level of detail from a global perspective, this volume offers a practical and complete resource compiled by a multidisciplinary and multinational team of experts. Beginning with a historical perspective on the disease, the textbook provides a comprehensive background in the epidemiology, diagnosis, and classification of axial spondyloarthritis. Immune mechanisms and genetics are covered, along with imaging and a detailed section on the range of treatments options currently available. A section on extra-articular manifestations provides a comprehensive knowledge base for the clinician treating patients with spondyloarthritis, and chapters on the economics of the disease, physical functioning, and patient registries complete the broad coverage of the topic. Practical, easy to use, yet detailed with respect to pathophysiology, diagnostics, and management, this textbook provides a comprehensive reference for rheumatologists, general practitioners, internists, and paediatricians managing patients with axial spondyloarthritis.
