concerns two different clinical entities: firstly, antinuclear antibody (ANA) positive patients who have a chronic anterior uveitis with severe complications and often a poor visual prognosis; secondly, usually HLA-B27 positive children, predominantly boys, with unilateral recurrent anterior uveitis. Three...
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...

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...
Positive- The positive results indicate a high risk of autoimmune disease. The presence of HLA-B27 increases the risk of developing autoimmune and inflammatory diseases like- Ankylosing spondylitis, Reactive arthritis, Juvenile idiopathic arthritis, Anterior uveitis, Behçet's disease, and Psoriatic arth...
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 ...

结论 益赛普治疗HLA-B27阳性uSpA患者临床效果显著,安全性和耐受性好。 Abstract Objective To evaluate the efficacy and safety of Etanercept in the treatment of undifferentiated spondyloarthropathies (uSpA) patients with positive HLA-B27. Methods The 56 uSpA patients carrying HLA-B27 were devided into ...
5-10% of the general population is HLA-B27 positive compared to patients with ankylosing spondylitis who are more than 90% positive. In addition, an increased incidence of the HLA-B27 antigen has been reported in patients with Reiter's syndrome, anterior uveitis, psoriatic arthritis and ...
Compared with the low-risk group, the positive rate of HLA-B27(76.19%, 93.55% vs 55.32%), the expression level of SAA(9.35±2.35ng/ml, 10.94±2.42ng/ml vs 8.23±2.23ng/ml)and the PSI score(108.63±12.47score, 145.93±12.44 score vs 54.48±17.31 score) in the middle-risk group and ...
