Can HLA-B27 be cured?

There’s no cure for ankylosing spondylitis (AS), but treatment is available to help relieve the symptoms. Treatment can also help delay or prevent the process of the spine joining up (fusing) and stiffening. In most cases treatment involves a combination of: exercise.

What organs does ankylosing spondylitis affect?

OA is more common than RA. Both involve inflammation in the joints, but RA causes much more inflammation. Until recently, experts believed that inflammation was not a feature of OA, and researchers are still investigating the role that it plays in the illness — whether it is a cause or a result of the condition.
