Ankylosing Spondylitis: Symptoms, Diagnosis, and Treatment - Rehabilitation

More Info

---

Ankylosing Spondylitis (AS) is a chronic inflammatory disease primarily affecting the spine and the sacroiliac joints, which are located at the base of the spine where it connects to the pelvis. It is classified as a type of spondyloarthritis and is characterized by inflammation that can lead to pain and stiffness in the back and hips. Over time, AS can cause the vertebrae to fuse together, resulting in a rigid spine.


Symptoms of Ankylosing Spondylitis
The symptoms of AS typically begin in early adulthood and can include:
1. Chronic Pain and Stiffness: The hallmark of AS is chronic pain and stiffness in the lower back and hips, particularly in the morning or after periods of inactivity. This pain often improves with physical activity and worsens with rest.

2. Reduced Flexibility: As the disease progresses, individuals may experience a reduction in spinal flexibility, making it difficult to bend or twist.

3. Fatigue: Many patients report feeling fatigued due to the chronic nature of the disease and the body's ongoing inflammatory response.

4. Peripheral Joint Pain: In addition to spinal symptoms, AS can also affect other joints, such as the knees, ankles, and shoulders.

5. Enthesitis: This refers to inflammation at the sites where tendons and ligaments attach to bone, commonly seen in the Achilles tendon and plantar fascia.

6. Extra-Articular Manifestations: AS can also be associated with other conditions, such as uveitis (inflammation of the eye), psoriasis, and inflammatory bowel disease.


Diagnosis of Ankylosing Spondylitis
Diagnosing AS can be challenging, as symptoms may overlap with other conditions. The diagnosis typically involves:
1. Clinical Evaluation: A thorough medical history and physical examination are crucial. Physicians will assess the pattern of pain, stiffness, and any associated symptoms.

2. Imaging Studies: X-rays can reveal changes in the sacroiliac joints and spine. MRI may be used to detect early inflammatory changes that are not visible on X-rays.

3. Blood Tests: Testing for the HLA-B27 antigen can help in the diagnosis, as a significant percentage of individuals with AS test positive for this marker. However, not all patients with AS are HLA-B27 positive, and not all HLA-B27 positive individuals develop AS.


Treatment of Ankylosing Spondylitis
While there is no cure for AS, treatment focuses on managing symptoms and preventing complications:
1. Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used to relieve pain and inflammation. In more severe cases, disease-modifying antirheumatic drugs (DMARDs) or biologics may be prescribed.

2. Physical Therapy: Engaging in regular physical therapy and exercise is essential to maintain flexibility and posture. Specific exercises can help strengthen the back and improve overall mobility.

3. Lifestyle Modifications: Maintaining a healthy weight, practicing good posture, and avoiding prolonged periods of inactivity can help manage symptoms.

4. Surgery: In rare cases, surgical intervention may be necessary for severe joint damage or deformity.


Conclusion
Given your symptoms of sacroiliac joint inflammation, chronic back pain, and the recent findings from imaging studies, it is important to continue working closely with your rheumatologist. While the absence of a family history of AS may seem reassuring, it does not rule out the possibility of developing the condition. The presence of inflammation in the sacroiliac joint is a significant indicator, and further evaluation of your blood tests will provide additional insights.

It is crucial to remain proactive in your treatment plan, including adhering to prescribed medications and engaging in physical therapy. If your symptoms persist or worsen, do not hesitate to seek a second opinion or further evaluation. Early diagnosis and intervention can significantly improve outcomes and quality of life for individuals with Ankylosing Spondylitis.
