What does a positive HLA-B27 antigen mean?
A positive test means HLA-B27 is present. It suggests a greater-than-average risk for developing or having certain autoimmune disorders. An autoimmune disorder is a condition that occurs when the immune system mistakenly attacks and destroys healthy body tissue.
How serious is HLA-B27?
The presence of HLA-B27 on your white blood cells can cause your immune system to attack those otherwise healthy cells. When this occurs, it can result in an autoimmune disease or immune-mediated disease, such as juvenile rheumatoid arthritis or ankylosing spondylitis.
What diseases are related to HLA-B27?
People with HLA-B27 have an increased likelihood of developing autoimmune diseases such as ankylosing spondylitis (AS), juvenile rheumatoid arthritis (JRA), reactive arthritis (of which one subset is Reiter syndrome), and isolated acute anterior uveitis.
Is HLA-B27 positive rare?
Research has shown more than 9 out of 10 people with AS carry a particular gene known as human leukocyte antigen B27 (HLA-B27). Having this gene does not necessarily mean you’ll develop AS. It’s estimated 8 in every 100 people in the general population have the HLA-B27 gene, but most do not have AS.
Is positive HLA-B27 an autoimmune disease?
“B27 disease” is a new autoimmune disease that afflicts millions of people throughout the world. “B27 disease” occurs in individuals who have ankylosing spondylitis (AS) or preankylosing spondylitis and/or uveitis and are also positive for HLA-B27.
Does HLA-B27 cause lupus?
The human leukocyte antigen B27 antigen was also found to be positive. We propose that development of systemic lupus erythematosus in this case may have been due to low grade chronic inflammation.
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.
What is the treatment of HLA-B27 positive?
Conclusions: Infliximab, adalimumab, and etanercept were effective for treating and reducing the number of uveitis relapses in HLA-B27-positive AS.
How do you treat HLA-B27 positive?
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.
Are you born with HLA-B27?
The HLA-B27 gene is found in 8% of the Caucasian population. Only about 2% of people born with HLA-B27 will get AS. This is because the protein made by HLA-B27 works with other proteins to cause the disease in ways that we don’t understand.
What autoimmune disease is HLA-B27?
Is HLA-B27 linked to MS?
