川崎病合并冠状动脉损害的遗传学基础

川崎病（KD）主要危及生命的并发症是冠状动脉损害（CAL）,引起冠状动脉狭窄、血栓形成、动脉瘤破裂等,甚至猝死。KD现已成为儿童后天性心脏病的主要病因。因此,早期发现哪些KD患儿是发生CAL的易患人群,并予及时干预十分重要。遗传因素在KD及其CAL的发生发展中起重要作用,目前已发现多个基因的多态性与CAL相关。该文主要就近年来国内外关于KD合并CAL基因多态性的研究作一综述。

The genetic basis of coronary artery lesions in Kawasaki disease

Kawasaki disease (KD) is an acute systemic vasculitis and its main life-threatening complications are coronary artery lesions(CAL), including coronary artery stenosis, thrombosis, aneurysm rupture, or sudden death. KD has now surpassed acute rheumatic fever as the leading cause of acquired heart disease in children. Therefore, it is important to identify as early as possible KD patients who are at risk for the development of CAL and intervent them timely. Genetic factors are thought to have important influences on the development and progress of Kawasaki disease and its CAL. In previous reports, several genetic polymorphisms, such as VEGF, MMPs and CD14 gene, were associated with the development of CAL. This review will introduce the study of gene polymorphisms in susceptibility to CAL in children with KD recently.
