In addition to ankylosing stenosis, what other diseases can b27 positive cause?

B27 antigen positivity is associated with a variety of autoimmune diseases, not just ankylosing spondylitis. If you have related symptoms, you should seek medical evaluation in time and do not take it lightly.

B27 is a specific HLA (human leukocyte antigen) type, and some people carry the B27 antigen, which is not a disease in itself, but may increase the risk of disease in some cases. Its most well-known association is ankylosing spondylitis, but it also involves other diseases, especially rheumatism and immunology-related problems.

Common diseases also include reactive arthritis, which may be caused by infection and manifests as joint swelling, pain, and fever. Psoriatic arthritis may also be associated with B27 positivity, and this disease is often accompanied by skin psoriasis symptoms. Inflammatory bowel disease-related arthritis also needs attention, which is usually combined with ulcerative colitis or Crohn's disease. The disease affects not only the joints, but may also cause intestinal discomfort such as diarrhea and abdominal pain.

For B27 positive people, preventive measures include: regular work and rest, avoid overwork and infection; maintain a healthy diet, eat more omega-3 foods rich in anti-inflammatory effects; regular physical exercise, strengthen physical fitness, especially low-load joint activities are good for health. If you feel joint swelling and pain, back stiffness or other abnormal symptoms, you should go to the rheumatology department for relevant examinations as soon as possible to get a clear diagnosis and timely treatment.
