Acute anterior uveitis (AAU) associated with human leukocyte antigen (HLA) B27 is the most common form of noninfectious intraocular inflammation and is considered to be aseparate clinical entity. Young adults between the ages of20 and40 years are predominantly affected. The HLA-B27 positive AAU ...
过去认为,HLA-B27分子与多肽(多为第2位为精氨酸的9肽)结合形成的复合物被CD8+细胞毒T淋巴细胞识别后触发的自身免疫反应是HLA-B27唯一的致病机制。但国外May等[9]发现,只表达转染的人HLA-B27重链,剔除了β2微球蛋白基因的HLA-B27转基因鼠仍可...
过去认为,HLA-B27分子与多肽(多为第2位为精氨酸的9肽)结合形成的复合物被CD8+细胞毒T淋巴细胞识别后触发的自身免疫反应是HLA-B27唯一的致病机制。但国外May等[9]发现,只表达转染的人HLA-B27重链,剔除了β2微球蛋白基因的HLA-B27转基因鼠仍可出现关节炎,这提示HLA-B27可不向CD8+T淋巴细胞递呈抗原而诱发关节炎...
Uveitis is strongly linked to HLA-B27 as well. Conversely, the presence of an isolated HLA-B27-positive uveitis confers a high risk for developing SpA [73]. HLA B27 positivity correlates with worse prognosis and more severe disease course in ReA compared to B27-negative patients [74]. Therefo...
Thirty-four consecutively admitted patients with acute anterior uveitis (AAU) were examined. The male to female ratio was 1.8: 1. Twenty-two patients (67%) were HLA B27 positive. Twelve (36%) had radiographical sacro-iliits; all were males and were HLA B27 positive. Three of them were ...
HLA-B27--associated acute anterior uveitis, a relatively common form of uveal inflammation, has a sufficiently characteristic presentation that the diagnosis is often suggested by clinical assessment, although testing for HLA-B27 status provides strong support for the diagnosis. This condition usually res...

they showed that not only these self-antigens and microbial antigens are recognized by T cell clonotypes from blood and SF of AS patients, but also from blood and eye fluid of HLA-B27 positive anterioruveitispatients. In this study presentation of selected antigens by HLA-B∗2705 but not...
AB0711Review of management of HLA B27 positive uveitis patient attending a tertiary hospital – how good are we? Background Delay in diagnosing Spondyloarthroapthy is well documented. One of the reasons for the delay is the presentation of these group of patients to different specialties due to...
