Ankylosing spondylitis or spinal degeneration?


Hello Doctor: I am the one who previously asked about my case in #200623.
My blood test and MRI reports have come back.
The blood test report (as mentioned by the immunologist) shows: HLA B27 negative, IgG in red, and will be followed up; hsCRP: 0.10 mg/dL, no issues with the blood test, CRP decreased from 0.2 to 0.1.
I have been taking Celebrex (due to my gastrointestinal issues, I only take it when I have pain, and sometimes I still feel pain after taking it).
The immunologist, based on previous X-rays, two blood test reports, and my response to medication, suspects that I have ankylosing spondylitis.
The MRI report (reviewed by the rehabilitation physician) indicates that the sacroiliac joints are normal, but there is degeneration in the spine.
I would like to ask the doctor:
1.
Previously, when I visited the immunologist for X-rays, it was noted that there was slight inflammation in the right sacroiliac joint (a little white, but not obvious), but now the rehabilitation physician's MRI report states that my sacroiliac joints are normal.
Can the condition of the sacroiliac joints fluctuate, or have they actually always been fine?
2.
If the sacroiliac joints are normal and the HLA B27 is negative, and I still experience the previously mentioned symptoms intermittently, could I still have ankylosing spondylitis?
3.
Can spinal degeneration cause morning lower back pain and stiffness? What treatment options should I seek? I am quite confused...

4.
My family has a history of degenerative arthritis; is my spinal degeneration related to this?
5.
Given all the above circumstances, should I continue to monitor for ankylosing spondylitis?

Mr. Chen, 20~29 year old female. Ask Date: 2023/10/14

Dr. Gao Jiankai reply Internal Medicine


Hello, thank you for your questions.
Here are my responses:
1.
I previously had an X-ray in the immunology department that showed a slight inflammation in the right sacroiliac joint (there was a bit of whiteness, but it was not obvious).
However, the MRI report from the rehabilitation department states that my sacroiliac joint is normal.
Can the condition of the sacroiliac joint fluctuate, or has it actually been fine all along? --> I believe it is more likely that there is nothing wrong.
X-ray results can have a higher margin of error, and MRI assessments are generally more accurate.
2.
If the sacroiliac joint is normal and the HLA-B27 blood test is negative, and the symptoms I mentioned earlier are intermittent, could I still have ankylosing spondylitis? --> There are diagnostic criteria for ankylosing spondylitis.
If HLA-B27 is negative, it is essential to correlate with typical clinical symptoms, especially characteristic back pain.
If there are no typical clinical symptoms and only intermittent nonspecific symptoms, the likelihood of ankylosing spondylitis significantly decreases.
However, since you are young and experience morning stiffness, it is advisable to remain cautious and continue monitoring.
3.
Can spinal degeneration cause morning back pain and stiffness? What treatment options should I seek? I'm quite confused...
--> This is less likely; even if it does occur, the duration would typically be short.
I recommend regular exercise, as maintaining physical activity is crucial for back health.
If symptoms persist, rehabilitation may be beneficial.
Additionally, it is advisable to continue follow-up with a rheumatologist to monitor for any typical symptoms of ankylosing spondylitis and any abnormal blood test results for timely treatment.
4.
My family has osteoarthritis; is my spinal degeneration related? --> Osteoarthritis is not typically hereditary, so there is no need for concern on that front.
5.
Given all of the above, should I continue to monitor for ankylosing spondylitis? --> Please refer to my response to question 3.
The Allergy, Immunology, and Rheumatology Department at Changhua Hospital is here to support you.

More Info


Ankylosing Spondylitis (AS) and spinal degeneration are two distinct conditions that can lead to significant discomfort and mobility issues, but they have different underlying causes and treatment approaches. Based on your recent test results and symptoms, let’s break down your concerns and provide clarity on your diagnosis and management options.

1. Understanding Your Diagnosis: Your HLA-B27 test result is negative, which is significant because a positive result is often associated with ankylosing spondylitis. Additionally, your MRI report indicates that your sacroiliac joints are normal, which further reduces the likelihood of AS. However, it is essential to note that AS can sometimes present with intermittent symptoms, and inflammation may not always be visible on imaging. The fact that you had a previous X-ray showing mild inflammation suggests that there may have been a transient inflammatory process, which can occur in conditions like reactive arthritis or other forms of spondyloarthritis.

2. Symptoms and Their Causes: The symptoms you describe, such as morning stiffness and pain in the lower back, can indeed be caused by spinal degeneration or degenerative disc disease. These conditions are characterized by the wear and tear of the spinal structures, leading to pain, stiffness, and sometimes nerve compression. Morning stiffness is particularly common in degenerative conditions due to the accumulation of fluid in the joints overnight, which can cause discomfort upon waking.

3. Treatment Options: Since your MRI indicates spinal degeneration, treatment typically focuses on managing pain and improving function. Nonsteroidal anti-inflammatory drugs (NSAIDs) like Celebrex can help reduce inflammation and pain, but if they are not effective or cause gastrointestinal issues, you might want to discuss alternative medications with your physician. Physical therapy is also crucial; it can help strengthen the muscles supporting your spine, improve flexibility, and reduce pain. Engaging in regular low-impact exercises, such as swimming or walking, can also be beneficial.

4. Family History and Its Implications: A family history of degenerative joint disease may suggest a genetic predisposition to similar conditions. While this does not directly cause your symptoms, it may indicate a higher likelihood of developing similar issues. It’s essential to monitor your symptoms and maintain open communication with your healthcare provider about any changes.

5. Follow-Up and Monitoring: Given your current situation, it may not be necessary to continue extensive follow-up specifically for ankylosing spondylitis, especially since your tests do not support this diagnosis. However, it is crucial to keep track of your symptoms and report any significant changes to your healthcare provider. If your symptoms worsen or new symptoms arise, further evaluation may be warranted.

In conclusion, while your symptoms may not align with ankylosing spondylitis due to the negative HLA-B27 test and normal MRI findings of the sacroiliac joints, spinal degeneration can certainly cause the discomfort you are experiencing. A multidisciplinary approach involving medication, physical therapy, and lifestyle modifications will likely provide the best outcomes for managing your symptoms. Always consult with your healthcare provider before making any changes to your treatment plan, and don't hesitate to seek a second opinion if you feel uncertain about your diagnosis or treatment options.
