Cure8 research brief
HLA-B27 is frequently found in people with certain non-infectious eye inflammations—especially acute anterior uveitis—and is often associated with systemic inflammatory diseases such as ankylosing spondylitis and, less commonly, inflammatory bowel disease.
For people with IBD or recurrent eye inflammation, understanding this link may prompt multidisciplinary evaluation.
Clinicians (ophthalmologists, rheumatologists, gastroenterologists), researchers studying HLA-B27–associated disease links, and patients with recurrent uveitis or known IBD.
This retrospective single-center study screened 6,253 consecutive patients referred for HLA-B27 testing between 2012 and 2023 to describe HLA-B27 positivity across non-infectious ocular diagnoses.
Overall HLA-B27 positivity was 16.8% (1,051/6,253), higher in males than females, and especially enriched in uveitis—acute anterior uveitis showed a 59.8% HLA-B27 positivity rate.
Among HLA-B27–positive patients, 741 had a documented systemic diagnosis; ankylosing spondylitis was most common (571 cases), and inflammatory bowel diseases were reported (63 ulcerative colitis, 15 Crohn’s disease).
The study used routine flow-cytometric HLA-B27 antigen testing on whole blood and linked positive results to rheumatology evaluation and existing clinical records.
It is a large retrospective laboratory-screening analysis from a tertiary ophthalmology referral cohort; the authors note that prospective controlled studies are needed to confirm causal or disease-specific links.
If you have recurrent acute anterior uveitis or other non-infectious ocular inflammation, this study reinforces the common association with HLA-B27 and with systemic conditions (especially ankylosing spondylitis and, less commonly, IBD), and supports multidisciplinary evaluation involving rheumatology.
This is a retrospective, single-center laboratory-screening study from a tertiary referral ophthalmology cohort; findings describe associations and frequency but do not prove causation. HLA-B27 testing was done as part of routine care and positive cases were linked to existing clinical records; prospective studies are needed to verify disease-specific relationships.

Recognizing eye inflammation as a possible early sign of IBD could shorten diagnostic delays and lead to earlier gastroenterology evaluation and treatment, which is especially important for children who often wait years...
Children with autoimmune gastrointestinal diseases can have impaired bone health.
Vitamin D deficiency was very common in this IBD cohort and was linked to Crohn’s disease and female sex, which may matter because deficiency can affect bone health and immune regulation in people with IBD.
