摘要:

儿童暴发性肝功能衰竭的病因与成人不同,大体上可分为6类:代谢性疾病、感染性疾病、药物/毒物性因素、自身免疫性疾病、血管性疾病、恶性肿瘤性疾病。而儿童暴发性肝衰竭的发病机制又因其病因的不同而异,确切的发病机制目前尚不十分清楚,但大体上可分为直接损伤和免疫介导的肝损伤两类,而细胞坏死和细胞凋亡则是暴发性肝衰竭的最终病理改变。本文就儿童暴发性肝功能衰竭的病因和发病机制进行综述。

Abstract:

The causes of acute liver failure (ALF) in children differ from those observed in adults. They can be schematically grouped into six categories: metabolic, infective, toxic, autoimmune, vascular and malignancy-induced ALF. Although the mechanisms of liver injury contributing to ALF vary due to different causes and are incompletely understood, they can be summarized into two categories: direct damage and immune-mediated liver injury. Cellular necrosis and apoptosis are the final changes of pathology. This article will review the current knowledge of the epidemiology and mechanisms of ALF in children.

Key words: acute liver failure, pediatric, epidemiology, pathogenesis
