The association with HLA-B27 has been demonstrated worldwide and evidence for a role of HLA-B27 in ankylosing spondylitis comes from linkage and association studies in humans and transgenic animal models However twin studies indicate that HLA-B27 contributes only 16 of the total genetic risk for the disease Furthermore there is

The seronegative spondyloarthropathies denote a family ofinflammatory arthritides that include ankylosing spondyli-tis psoriatic arthritis Reiter’s disease (also known asReiter’s spondylitis Reiter’s syndrome or reactive spondy-loarthritis) and enteropathic spondylitis (also known asspondylitis of inflammatory bowel disease)
Does HLA B27 cause spondyloarthropathies?
- HLA B27 has been primarily associated with susceptibility to develop spondyloarthropathies, which are chronic, inflammatory joint diseases. Spondyloarthropathies include ankylosing spondylitis (AS), a subset of psoriatic arthritis, reactive arthritis, arthritis associated with inflammatory bowel disease, and undifferentiated spondyloarthropathy.
What happens if you have a positive HLA-B27 test?
- But only 2 % of people who have a positive HLA-B27 go on to develop ankylosing spondylitis. About 50% of people with psoriatic arthritis that involves the spine have a positive HLA-B27. 60% of people diagnosed with reactive arthritis have a positive HLA-B27.
Are hla-b27-restricted cytotoxic T lymphocytes associated with spondyloarthropathy?
- If the disease association of HLA-B27 is indeed a consequence of its physiological role in peptide presentation, HLA-B27-restricted cytotoxic T lymphocytes (CTL), specific for self-epitopes or bacterial epitopes, should be demonstrable in the involved joints of patients with spondyloarthropathies.
Is the HLA-B27 antigen important for PSSPA susceptibility?
- The HLA-B27 antigen is not only important for PsSpA susceptibility, but also determines some clinical features. This antigen was associated with earlier age of psoriasis and arthritis onset, bilateral sacroiliitis, and male gender. However, it was not associated with either the severity or extension …
