HLA-B27相关前葡萄膜炎的研究进展

Advancement in the investigation of HLA-B27 associated anterior uveitis

HLA-B27阳性前葡萄膜炎是前葡萄膜炎最常见的类型,患者多为青壮年,反复发作,常引起一些并发症,严重影响视力,并可伴有其他系统性疾病。但其发病机制目前仍不清楚,尚无特效的治疗方法。近年来,建立了一些前葡萄膜炎动物模型,如内毒素诱导的前葡萄膜炎和HLA-B27转基因动物模型,并进行了一系列的研究。一些新的治疗方法在临床及动物实验中也取得了很好的疗效。就HLA-B27相关前葡萄膜炎的发病机制、流行病学、动物模型及一些新的治疗方法进行综述。

Uveitis is an important autoimmune disease.Human leukocyte antigen（HLA）-B27-associated anterior uveitis is the most common form of anterior uveitis.HLA-B27-associated anterior uveitis has distinct ocular,systemic,and genetic features.It attacks young subjects and leads to the damage of visual function due to the recurrence and complications.However,the pathologic mechanism of HLA-B27-associated anterior uveitis is still not thoroughly understood,and effective therapy is still unavailable.There are currently many experimental researches which attamp to study the etiology and develop an effective therapy for HLA-B27 acute anterior uveitis.Thus,various animal models of acute anterior uveitis such as endotoxin-induced uveitis and HLA-B27 transgenic animals including rat and mouse are established.Different therapy regimens have been designed both in clinical trial and experimental study and aquired promising achievements.Epidemiology,pathologic mechanism,different animal models and potential new therapies such as anti-TNFα,oral associated peptides tolerance and gene therapy are overviewed.
