Effectiveness and Safety of Spondylitis Related to Inflammatory Bowel Disease

Adalimumab is an antibody treatment that targets and neutralizes a molecule produced in the body that is associated with inflammation, tumor necrosis factor (TNF). This molecule is an important factor in causing the inflammation seen in people with a form of inflammatory spinal arthritis called spondylitis as well as inflammation in the bowel called Crohn's disease. Spondylitis and Crohn's disease tend to go together and this study will assess to what degree this treatment is effective for those patients that have both disorders at the same time.
