单纯疱疹病毒1型(HSV-1)感染了世界上大多数人口。这些感染通常是无症状的,但眼部HSV-1感染会导致多种病理变化,其中最具破坏性的可能是疱疹间质角膜炎(HSK)。HSK病变本质上是免疫性炎症,可在一生中反复发作,经常导致进行性角膜瘢痕,从而导致视力障碍。目前的治疗包括广泛的局部免疫抑制,使用局部类固醇,同时覆盖抗病毒药物。不幸的是,HSK动物模型中定义的免疫病理机制尚未转化为改进的治疗方法。在此,我们回顾了该病的临床流行病学和病理学,并总结了大量关于HSK免疫病理学的基础研究。我们研究了先天性和获得性免疫系统在清除病毒和破坏HSK典型的正常角膜结构中的作用。我们的目标是明确目前对HSK的致病机制和复发性质的认识,并确定需要进一步研究的领域。
Herpes Simplex Virus-1 (HSV-1) infects the majority of the world’s population. These infections are often asymptomatic, but ocular HSV-1 infections cause multiple pathologies with perhaps the most destructive being Herpes Stromal Keratitis (HSK). HSK lesions, which are immunoinflammatory in nature, can recur throughout life and often cause progressive corneal scaring resulting in visual impairment. Current treatment involves broad local immunosuppression with topical steroids along with antiviral coverage. Unfortunately, the immunopathologic mechanisms defined in animal models of HSK have not yet translated into improved therapy. Herein, we review the clinical epidemiology and pathology of the disease and summarize the large amount of basic research regarding the immunopathology of HSK. We examine the role of the innate and adaptive immune system in the clearance of virus and the destruction of the normal corneal architecture that is typical of HSK. Our goal is to define current knowledge of the pathogenic mechanisms and recurrent nature of HSK and identify areas that require further study.
