非酒精性脂肪性肝病(non-alcoholic fatty liver disease，NAFLD)本质上是一种肝代谢性疾病，其发病机制复杂，目前尚未完全明确。目前各项资料显示幽门螺杆菌感染(Helicobacter pylori，Hp)与NAFLD的发生和发展有密切的关系，但也有研究得出了相反的结论。对于存在争议的部分至今尚未解决，但如证实Hp感染可作为NAFLD的一种独立危险因素存在，则对NAFLD发病预测以及治疗提供帮助，因此研究两者相关性的工作仍然具有临床意义。
Relationship between non-alcoholic fatty liver disease and Helicobacter pylori infection
Non-alcoholic fatty liver disease (NAFLD) is essentially a liver metabolic disease, its pathogenesis is complex and not yet completely clear. All information shows that Helicobacter pylori (Hp) infection and NAFLD have a close relationship in the occurrence and development. but there are also some researches drawing the opposite conclusion, the still controversial parts have not yet been resolved, but if it is confirmed that Hp infection can exist as an independent risk factor of NAFLD, it is of great help to the pathogenesis of NAFLD prediction and treatment, so the research on correlation still has clinical significance.
