Ankylosing Spondylitis: Early Signs, Causes, Diagnosis, Treatment & Life Strategies

What is Ankylosing Spondylitis?

Ankylosing spondylitis (AS) is a chronic, progressive inflammatory condition that primarily affects the spine and sacroiliac joints, which connect the spine to the pelvis. Over time, this disease can lead to the fusion of spinal vertebrae—a process called ankylosis—causing a significant reduction in mobility, flexibility, and function. The hallmark of AS is inflammatory back pain that improves with physical activity but worsens with rest.

AS is categorized under the umbrella of axial spondyloarthritis, a broader term that includes radiographic (visible changes in imaging) and non-radiographic forms. It’s also considered an autoimmune disorder, where the immune system attacks the body’s own tissues, primarily targeting the axial skeleton.

While it most commonly presents in young adults, particularly males, between 17 and 45 years of age, AS can also affect older individuals and, in rare cases, children (juvenile-onset AS). Early recognition and a proactive management plan are essential to maintain function and quality of life.

Early Signs and Symptoms of Ankylosing Spondylitis

Early symptoms of ankylosing spondylitis can often be subtle or misinterpreted as typical back strain, making diagnosis difficult. Symptoms usually develop gradually and may progress over several years.

Common Symptoms of Ankylosing Spondylitis:

Persistent lower back pain: Especially in the morning or after periods of inactivity.
Morning stiffness: Lasting more than 30 minutes and easing with movement.
Pain in sacroiliac joints: Felt in the hips, buttocks, or lower spine.
Fatigue: Chronic inflammation can cause systemic fatigue, impacting productivity and mental well-being.

Uncommon or Overlooked Symptoms:

Uveitis or Iritis: Inflammation of the eye that can cause redness, pain, light sensitivity, and blurred vision. This occurs in up to 40% of patients with AS.
Costochondritis: Inflammation where the ribs meet the breastbone, causing chest pain.
Enthesitis: Pain where tendons and ligaments attach to bone, such as at the heels (Achilles tendon).
Loss of appetite and mild weight loss: Often a result of systemic inflammation.
Restricted chest expansion: Due to fusion in the thoracic spine, leading to breathing difficulties.

Symptoms often appear in flares, interspersed with periods of remission, and may also migrate or alternate sides of the body.

Causes and Risk Factors of Ankylosing Spondylitis

Although the specific cause of ankylosing spondylitis remains unclear, researchers believe a combination of genetic predisposition and environmental triggers contributes to disease onset.

Genetic Factors:

HLA-B27 Gene: This gene is present in over 90% of AS patients of European descent. However, its presence does not guarantee disease development. Individuals without the gene can also develop AS, albeit less commonly. The presence of HLA-B27 is associated with earlier disease onset and a more aggressive course.

Other Genetic Markers:

ERAP1 and IL23R genes: These may also contribute to immune system dysfunction in AS.

Environmental Triggers:

Infections: Certain bacterial infections may act as a trigger in genetically predisposed individuals, especially in the gut.
Smoking: Not only a trigger but also an exacerbator of disease progression and lung complications.

Risk Factors:

Male sex: AS is more prevalent and severe in males, although females may present with more subtle symptoms.
Family history: A strong predictor of disease.
Age of onset: Most commonly between 17–45 years.
Ethnicity: More common in people of Northern European descent.

Diagnostic Process for Ankylosing Spondylitis

Timely diagnosis of AS can be challenging but is essential to initiate early treatment and prevent structural damage.

Step-by-Step Diagnosis:

Comprehensive Medical History:
- Duration and nature of back pain
- Family history of autoimmune diseases
- Patterns of stiffness and symptom relief
Physical Examination:
- Assess spinal mobility, posture, and chest expansion
- Look for tenderness in sacroiliac joints
Blood Tests:
- HLA-B27 testing: Not definitive but helpful in context
- CRP and ESR: Markers of systemic inflammation
- CBC (Complete Blood Count): May show mild anemia
Imaging Techniques:
- X-rays: May reveal sacroiliitis (inflammation of the sacroiliac joints)
- MRI: Superior for detecting early inflammation and soft tissue changes
ASAS Classification Criteria (Assessment of SpondyloArthritis International Society):
- Includes imaging findings, genetic markers, and clinical features like inflammatory back pain, arthritis, uveitis, and family history

Diagnosing AS early, particularly non-radiographic forms, allows more effective use of biologics and preventive care.

Treatment Options for Ankylosing Spondylitis

While there is no known cure, modern therapies offer significant relief and can slow disease progression when initiated early.

1. Medications for Ankylosing Spondylitis

NSAIDs

These are the frontline medications for symptom control.
Common examples include naproxen, diclofenac, and indomethacin.
They help alleviate stiffness, pain, and inflammation, particularly during flares.

Biologic Agents

Biologics are immune-modulating drugs that target specific inflammatory cytokines.

TNF-alpha inhibitors:
- Etanercept (Enbrel)
- Adalimumab (Humira)
- Infliximab (Remicade)
IL-17 inhibitors:
- Secukinumab (Cosentyx)
- Ixekizumab (Taltz)

These are often prescribed when NSAIDs fail to provide adequate relief or in patients with high disease activity.

DMARDs

Disease-Modifying Antirheumatic Drugs like sulfasalazine may help peripheral joint involvement.
Not typically effective for spinal symptoms.

Corticosteroids

Oral or injectable steroids for short-term use during acute flares.
Not suitable for long-term management due to side effects.

2. Physical Therapy and Rehabilitation

Exercise is a cornerstone of AS treatment.

Stretching exercises improve flexibility and posture
Breathing exercises enhance chest expansion
Water-based therapy offers joint-friendly resistance and cardiovascular benefits
Postural training helps maintain spinal alignment

Routine physical activity is associated with less pain, improved mobility, and reduced disability.

3. Surgical Interventions for Ankylosing Spondylitis

In advanced cases, surgery may be required:

Hip replacement for severe joint damage
Spinal osteotomy to correct severe kyphosis (spinal deformity)

Lifestyle and Holistic Management for Ankylosing Spondylitis

Lifestyle changes are crucial to managing symptoms, preventing flare-ups, and maintaining quality of life.

Nutritional Strategies:

Focus on anti-inflammatory foods:
- Salmon, flaxseed, chia seeds (rich in omega-3s)
- Dark leafy greens, berries, turmeric, and ginger
Reduce intake of:
- Refined sugar, processed foods, and trans fats

Weight and Activity:

Maintaining a healthy weight reduces pressure on joints
Daily activity, even in short bursts, prevents stiffness

Smoking and Alcohol:

Quit smoking: It accelerates spinal fusion and reduces lung capacity
Limit alcohol: Excessive consumption can interact with medications and affect bone health

Sleep and Rest:

Sleep on a firm mattress with minimal pillow use
Practice sleep hygiene to manage fatigue

Mental Health:

Practice mindfulness meditation, guided imagery, or journaling
Seek help from mental health professionals for anxiety or depression
Join support groups for community and shared experiences

Expert-Backed Strategies to Live Well with AS

Living with AS means adopting an informed, consistent, and proactive approach.

Complementary Therapies:

Acupuncture: May help reduce musculoskeletal pain
Massage therapy: Alleviates muscle tension and stress
Yoga and Pilates: Improve flexibility and body awareness

Workplace Tips:

Adjust workstations for ergonomic alignment
Use standing desks or alternate sitting and standing

Travel Tips:

Pack mobility aids or ergonomic supports
Stretch every 1–2 hours during long journeys

Long-Term Management Goals:

Regular rheumatologist visits for medication monitoring
Annual eye exams to catch uveitis early
Stay informed about new treatments and research trials
