Axial Spondyloarthritis: Is It a Kind of Arthritis?

Axial spondyloarthritis (axSpA) is a chronic inflammatory disease that primarily affects the spine. While the term “arthritis” might bring to mind worn-down joints and primarily affects older adults, axSpA typically emerges in early adulthood and involves inflammation where tendons and ligaments attach to bones, especially in the spine. This can cause pain, stiffness, and, over time, lead to the fusion of spinal bones.

Understanding Axial Spondyloarthritis

AxSpA falls under the umbrella of spondyloarthritis, a group of inflammatory diseases that can impact the spine and other joints. It’s important to note that while axSpA shares some similarities with other forms of arthritis, like rheumatoid arthritis, it has its own distinct characteristics.

One of the key differences lies in the target of the immune system. In rheumatoid arthritis, the immune system mistakenly attacks the lining of the joints (synovium). However, in axSpA, the immune system primarily targets the entheses, which are the points where tendons and ligaments attach to bones.

Types of Axial Spondyloarthritis

Axial spondyloarthritis is broadly categorized into two main types:

  • Radiographic axSpA (previously ankylosing spondylitis): This type is characterized by visible damage on X-rays, particularly in the sacroiliac joints of the pelvis and the spine.
  • Non-radiographic axSpA: Individuals with this type experience symptoms of axSpA, but significant damage isn’t yet apparent on X-rays. However, magnetic resonance imaging (MRI) might reveal early signs of inflammation.

Symptoms and Diagnosis

The symptoms of axSpA can vary from person to person and may fluctuate over time. Common signs include:

  • Lower back pain and stiffness: This pain is often worse in the morning or after periods of inactivity.
  • Pain and stiffness in the buttocks and hips: The pain may alternate from one side to the other.
  • Neck pain and stiffness: This symptom is more common in advanced stages of the disease.
  • Fatigue: Persistent fatigue is a common complaint among those with axSpA.
  • Eye inflammation (uveitis): This condition can cause pain, redness, and blurred vision.

Diagnosing axSpA can be challenging because the symptoms often overlap with other conditions. Doctors typically use a combination of methods to reach a diagnosis, including:

  • Medical history and physical exam: The doctor will inquire about symptoms, family history, and examine your posture and range of motion.
  • Blood tests: While there’s no single blood test to diagnose axSpA, tests for inflammation markers like C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) can be helpful.
  • Imaging tests: X-rays can reveal joint damage in later stages of axSpA. MRIs are more sensitive and can detect early signs of inflammation in the spine and sacroiliac joints.

Treatment and Management

While there’s currently no cure for axial spondyloarthritis, various treatment options can help manage the symptoms, slow down the progression of the disease, and improve quality of life.

  • Medications:

    • Nonsteroidal anti-inflammatory drugs (NSAIDs) are often the first line of treatment to reduce pain and inflammation.
    • Disease-modifying antirheumatic drugs (DMARDs) can help slow down the progression of the disease.
    • Biologic agents, such as tumor necrosis factor (TNF) inhibitors, target specific proteins involved in inflammation and can be highly effective in managing axSpA.
  • Physical therapy: Regular exercise and physical therapy are crucial for maintaining flexibility, range of motion, and muscle strength. Specific exercises can help improve posture, reduce stiffness, and strengthen back muscles.

  • Lifestyle modifications: Maintaining a healthy weight, quitting smoking, and practicing good posture can help manage axSpA symptoms and improve overall health.

Living with Axial Spondyloarthritis

Living with a chronic condition like axSpA can be challenging, but with the right treatment plan and support system, individuals can live fulfilling and active lives.

Remember that early diagnosis and treatment are crucial in managing axSpA and preventing complications. If you’re experiencing persistent back pain, especially if it’s worse in the morning or after rest, consult a healthcare professional to discuss your symptoms and determine the underlying cause.
