Analysis of HLA Profiles in 390 Uveitis Cases: Insights into Clinical Presentations
Objective:
This study aimed to explain the associations between different types of uveitis and human leukocyte antigen (HLA)-B27, HLA-DR4, and HLA-DRw53.
Methods:
A retrospective analysis of 390 uveitis cases was conducted among inpatients and outpatients diagnosed at Weifang Eye Hospital from 2013 to 2016. All 390 patients underwent HLA-B27 examination, and an additional 40 patients underwent examination for HLA-DR4 and HLA-DRw53. Gender, age, corrected visual acuity (CVA), and recurrence frequency were statistically analyzed based on the onset site and etiology classification.
Results:
Among the 390 enrolled patients, 206 were male, and 183 were female, with ages ranging from 6 to 87 years (mean: 44.2). The disease onset was classified into anterior uveitis (AU), panuveitis (panU), posterior uveitis (PU), and intermediate uveitis in 180, 112, 88, and 10 cases, respectively. HLA-B27 was positive in 94 cases (53 males and 41 females), yielding a positive rate of 24.1%. In AU patients, 80 (44.4%) tested positive for HLA-B27, while 8 (7.1%) panU patients and 6 PU patients (6.8%) were HLA-B27 positive; none of the intermediate uveitis (IU) patients exhibited HLA-B27 positivity. HLA-B27, HLA-DR4, and HLA-DRw53 examinations were performed on 40 patients with binocular uveitis, resulting in 2 HLA-B27 positive cases, 15 HLA-DR4 positive cases, and 20 HLA-DRw53 positive cases, with positive rates of 5%, 37.5%, and 50%, respectively. Among 25 Vogt Koyanagi-Harada (VKH) cases, 1 tested positive for HLA-B27, 22 were positive for HLA-DR4, and 24 were positive for HLA-DRw53, with positive rates of 4%, 88%, and 96%, respectively. No positive HLA-B27, HLA-DR4, or HLA-DRw53 cases were found among the 10 cases of Behcet's disease (BD).
Conclusions:
Human leukocyte antigens (HLAs) play a significant role in the mechanism of uveitis. HLA-B27 exhibits high diagnostic value in acute AU, while HLA-DR4 and HLA-DRw53 are crucial for diagnosing binocular uveitis, particularly Vogt Koyanagi-Harada (VKH) syndrome. Further investigation is warranted to explore the relationship between HLA-DR4, HLA-DRw53, and uveitis.
