Ankylosing Spondylitis (AS) is a type of progressive arthritis that leads to chronic inflammation of the spine and sacroiliac joints. It can also affect other joints and organs in the body, such as the eyes, lungs, kidneys, shoulders, knees, hips, heart, and ankles.
Ankylosing spondylitis is a cause of back pain in adolescents and young adults. The tendency to develop ankylosing spondylitis is genetically inherited. The HLA-B27 gene can be detected in the blood of most patients with ankylosing spondylitis. Ankylosing spondylitis can also affect the eyes, heart, lungs, and occasionally the kidneys.
