04 Dec Treatment Options for axSpA: From NSAIDs to Biologics
Axial spondyloarthritis (axSpA) is a chronic inflammatory disease that primarily affects the spine and sacroiliac joints, leading to pain, stiffness, and reduced mobility. For some, axSpA remains relatively mild, while for others it progresses to ankylosing spondylitis (AS), where spinal bones may fuse.
Although there is no cure, treatment options have expanded dramatically in recent years. Patients now have multiple approaches available to reduce inflammation, preserve mobility, and improve quality of life. This article walks through the main **treatment options for axSpA—from NSAIDs to biologics—and what patients and families need to know.
The Goals of axSpA Treatment
Every treatment plan is tailored to the individual, but doctors generally aim to:
- Reduce pain and stiffness.
- Control inflammation and prevent flares.
- Slow or stop structural damage.
- Improve physical function and daily mobility.
- Maintain quality of life.
Achieving these goals often requires a stepwise approach, beginning with conventional treatments and moving to advanced therapies if symptoms remain uncontrolled.
1. Nonsteroidal Anti-Inflammatory Drugs (NSAIDs)
NSAIDs are the first-line treatment for most people with axSpA. They reduce inflammation and provide pain relief, often improving morning stiffness and mobility.
- Examples: Ibuprofen, naproxen, indomethacin, diclofenac.
- How they work: Block enzymes (COX-1 and COX-2) involved in the inflammatory pathway.
- Effectiveness: Many patients notice significant symptom relief within days to weeks.
Pros:
- Widely available.
- Relatively inexpensive.
- Fast-acting relief for pain and stiffness.
Cons:
- Long-term use increases the risk of stomach ulcers, kidney problems, and cardiovascular issues.
- Some patients may not respond adequately to NSAIDs.
When used: As the first treatment step, often tried in different types or doses before moving to stronger options.
2. Physical Therapy and Exercise
While not a medication, physical therapy is essential for axSpA management. In fact, it’s often as important as drug therapy.
- Benefits: Maintains flexibility, improves posture, strengthens supporting muscles, and prevents spinal fusion.
- Exercises: Stretching, swimming, yoga, Pilates, and posture training are especially beneficial.
- Role of PTs: Physical therapists tailor routines to each patient’s needs, focusing on safe mobility.
Key point: Exercise is medicine for axSpA—patients who remain physically active often do better long-term than those who rely on medications alone.
3. Corticosteroids
Unlike some other autoimmune diseases, systemic corticosteroids (like prednisone) are not typically used long-term in axSpA because they are less effective for spinal inflammation. However, they do play a role:
- Local steroid injections: Into joints or entheses (where tendons attach to bone) can provide relief in specific areas.
- Short courses of oral steroids: Sometimes used during severe flares.
Risks of long-term use: Weight gain, osteoporosis, diabetes, and increased infection risk.
Key point: Steroids are generally a short-term or targeted tool, not a primary treatment for axSpA.
4. Conventional Disease-Modifying Antirheumatic Drugs (cDMARDs)
Traditional DMARDs, like methotrexate and sulfasalazine, are highly effective in rheumatoid arthritis but are less effective for spinal inflammation in axSpA.
- When used:
- More helpful for peripheral arthritis (hips, knees, ankles).
- Sometimes prescribed alongside biologics for broader immune control.
Limitations: Do not significantly slow axial disease progression.
5. Biologic Therapies
Biologics have transformed the treatment landscape for axSpA. These advanced medications target specific parts of the immune system, offering powerful inflammation control.
a. TNF Inhibitors
- Examples: Adalimumab (Humira), etanercept (Enbrel), infliximab (Remicade), certolizumab pegol (Cimzia), golimumab (Simponi).
- How they work: Block tumor necrosis factor (TNF), a key inflammatory cytokine in axSpA.
- Effectiveness: Improve spinal pain, mobility, fatigue, and quality of life. Can also treat extra-articular features like uveitis, psoriasis, and inflammatory bowel disease (IBD).
Pros: Established safety profile, effective in many patients.
Cons: Risk of infections, expensive, require injections or infusions.
b. IL-17 Inhibitors
- Examples: Secukinumab (Cosentyx), ixekizumab (Taltz).
- How they work: Block interleukin-17 (IL-17), another cytokine driving inflammation.
- Effectiveness: Especially helpful in patients who don’t respond to TNF inhibitors. Also effective for skin psoriasis.
Pros: Alternative for TNF non-responders, strong data in axSpA and psoriatic arthritis.
Cons: May worsen IBD in some patients, increased infection risk.
c. Newer Biologics Under Investigation
- IL-23 inhibitors and JAK inhibitors are being studied for axSpA.
- JAK inhibitors (like tofacitinib and upadacitinib) are already approved for rheumatoid and psoriatic arthritis, with promising results for axSpA in clinical trials.
6. Lifestyle and Supportive Therapies
Medications are only part of treatment. Long-term success also depends on daily self-care and lifestyle adjustments:
- Stop smoking: Smoking accelerates spinal damage in axSpA.
- Healthy diet: Anti-inflammatory diets rich in vegetables, lean proteins, and omega-3 fatty acids may help.
- Sleep management: Good sleep hygiene reduces fatigue.
- Mental health support: Counseling and support groups help patients cope with chronic pain and uncertainty.
Monitoring and Safety in Treatment
Because many axSpA treatments suppress the immune system, regular monitoring is essential:
- Blood tests (liver function, kidney function, blood counts).
- Tuberculosis and hepatitis screening before starting biologics.
- Ongoing monitoring for infections or unusual symptoms.
Patients should also keep regular rheumatology appointments to assess disease activity and adjust treatment.
Stepwise Treatment Approach
In practice, treatment for axSpA usually follows this path:
- NSAIDs + physical therapy/exercise → first line.
- If inadequate response → biologics (usually TNF inhibitors first, then IL-17 inhibitors if needed).
- If biologics are not tolerated → participation in clinical trials or use of new agents (like JAK inhibitors).
- Supportive care (pain management, counseling, lifestyle changes) is ongoing at every stage.
What Patients Should Ask Their Doctor
- Which treatment is best for me right now—NSAIDs, biologics, or a combination?
- How will we monitor whether treatment is working?
- What side effects should I watch for?
- If NSAIDs don’t help, when should we consider biologics?
- Are there lifestyle changes that could improve my outcomes?
- Am I eligible for clinical trials of newer therapies?
Final Thoughts
Axial spondyloarthritis is a lifelong condition, but treatment has advanced to the point where most patients can maintain mobility, reduce pain, and live fulfilling lives. The treatment journey often starts with NSAIDs and physical therapy, but biologics have revolutionized care, offering targeted control of inflammation and protection from long-term damage.
Key takeaway: Early diagnosis and proactive treatment make the biggest difference. If you have axSpA, work closely with your rheumatologist, stay active, and don’t hesitate to ask about newer therapies. The future for axSpA patients is brighter than ever.
