Brief Summary: This study will explore how genes may influence the severity of ankylosing spondylitis a form of arthritis that affects the spine Patients have inflammation of the joints of the spine which may cause the bones of the spine to fuse resulting in difficulty performing daily activities

Patients who developed ankylosing spondylitis after age 16 may be eligible for this study The onset of disease is dated to the first appearance of symptoms of inflammatory low back pain or restricted spinal motion Patients with a spondyloarthropathy other than AS may not participate Candidates will be screened with a medical history and physical examination blood test and review of their medical records They will also complete a questionnaire about their disease symptoms and medical history

Those enrolled in the study will return to the NIH Clinical Center at 6 12 18 24 30 36 42 48 54 and 60 months after screening for examination of the joints measurement of flexibility of the spine and a blood test They will also complete symptoms assessment and coping questionnaires At the first study visit screening visit x-rays will be taken of the pelvis lower back and neck if recent X-rays within 1 year are not available These x-ray studies will be repeated on all patients every two years during the study at 24 and 48 months after screening
Detailed Description: The susceptibility to ankylosing spondylitis AS is largely genetically determined Recent studies suggest that the severity of AS is also influenced by genetic factors The goal of this study is to identify genes that influence the severity of AS We hypothesize that genetic markers of susceptibility including human leukocyte antigen HLA polymorphisms and genes that regulate inflammation and bone formation influence the severity of AS

In this prospective longitudinal study we will test the association of several genetic markers with the severity of AS Approximately 700 patients will be included Measures of AS severity will be patient-reported pain and stiffness functional disability patient and physician global assessments joint counts number of tender entheses spinal mobility and laboratory measures of inflammation These measures will be assessed every 6 months for 5 years We will also evaluate new laboratory tests as measures of the activity of AS

Identifying genetic markers that are associated with differences in the severity of active inflammation in AS will enhance our understanding of the pathogenesis of this disease by suggesting mechanisms and pathways involved in the development of long-term damage
