About Ankylosing Spondylitis (AS)

Ankylosing Spondylitis can be one of the Extraintestinal Manifestations seen with IBD.

Ankylosing Spondylitis (AS) is an Inflammatory disease of the spinal column and pelvis. It is a Chronic disease which leads to fusion of the affected joints. AS can cause Chronic Pain and stiff joints. Most often in the lower back and/or hips.

Ankylosing Spondylitis (AS) is a Chronic type of Arthritis affecting the Spine and Sacroiliac Joint. It primarily affects males in their mid 20s, although females can also be affected by the disease. [5] AS Symptoms often begin in the 20's (but symptoms can begin earlier or later). Pain is typically worse during periods of immobility (such as at night or in the morning). Risk factors include: Family History of AS, Genetics, and frequent Gastrointestinal (GI) or Urinary Tract Infections. [4] Many people with AS also have Crohn's Disease or Ulcerative Colitis.

Common Symptoms:

Anemia (mild to moderate)[4]
Fatigue [4]
Lower Back / Buttocks Pain and Stiffness [4]
Pain in Joints may spread up the Spine, Neck and Peripheral Joints[4]

Joints Affected:

Rarely, patients with AS have pain in small joints or joints of the arm. Typically joints affected by AS include:
Sacroiliac Joint (Typical Presenting Joint) [4]

Laboratory and Diagnostic Tests:

- Anemia (Mild)
- ESR (Erythrocyte Sedimentation Rate) - shows presence of Inflammation but is not specific for AS nor is it elevated in all AS patients[4]
- MRI (or X-Ray) showing damage to the Sacroiliac Joint (may not be seen in early disease) [4]
- RF (Rheumatoid Factor) - Negative[4]
- ANA (Anti Nuclear Antibody) - Negative[4]


Biologics (Anti - Tumor Necrosis Factor (TNF) Agents) [5] [4]
NSAIDs **To be used with caution in patients with GI Disease[4]
Transcutaneous Electrical Nerve Stimulation (TENS)[4]
