Foreword to Ankylosing Spondylitis
Ankylosing spondylitis (AS) is an important topic in rheumatology, as it represents a distinct form of inflammatory arthritis primarily affecting the spine and sacroiliac joints. Understanding AS is crucial because it can lead to significant disability and impact quality of life if not adequately managed. This article will cover recent medication advances, which provide new hope for patients dealing with this chronic condition.
Definition and Pathophysiology
Ankylosing spondylitis is characterized by chronic inflammation of the spine, often resulting in painful stiffness and eventually fusion of vertebrae. The condition typically begins in early adulthood and can progress significantly over time. The exact cause of AS remains unclear but is believed to involve a combination of genetic and environmental factors. The presence of HLA-B27 antigen is commonly associated with the disease, suggesting a genetic predisposition.
The pathophysiological mechanism involves an autoimmune response where the body mistakenly targets its own tissues. In particular, inflammation occurs in the entheses, the sites where tendons and ligaments attach to bones. Over time, prolonged inflammation leads to structural changes, including new bone formation and reduced spinal mobility. Understanding these mechanisms helps in developing targeted therapies that can manage inflammation and slow disease progression.
