No results posted yet for this study

Summary

This study will explore how genes-units of heredity-may influence the severity of ankylosing spondylitis. It will examine whether some genes may cause people with ankylosing spondylitis to have more rapid fusion of the bones of the spine, more difficulty performing daily activities, or be more likely to need joint surgery.

Patients who developed ankylosing spondylitis after age 16 and have had the disease for 20 years or more 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 enroll.

Participants will complete a brief medical history and physical exam. They will fill out a 30-minute questionnaire that includes questions on demographics (such as age, ethnicity, marital status, etc.), medication history, work history, hip surgeries, and assessment of functional disability. Fifty milliliters (about 3-1/3 tablespoons) of blood will be drawn for gene testing, and X-rays will be taken of the pelvis, lower back, and neck, if recent X-rays (within 1 year) are not available. Women of childbearing age will have a urine pregnancy test before having X-rays.
