OBJECTIVES
It has been shown that the HCV-core protein reduces the activity of microsomal triglyceride transfer protein (MTP) and could lead to steatosis in HCV-infected patients. The aim of our study was to investigate the influence of a functional polymorphism in the promoter region of the MTP gene (493G/T) on the development of HCV-related steatosis.
METHODS
Eighty-six chronic hepatitis C patients were studied to assess: the effects of body mass index, age, HCV genotype, and 493G/T MTP polymorphism on steatosis.
RESULTS
Steatosis was observed in 39 patients (45.3%). The 493G/T MTP polymorphism were not related to the development of steatosis.
CONCLUSION
The functional G/T MTP polymorphism do not seem to play any role in the development of steatosis in chronic hepatitis C.
目的
研究表明，丙型肝炎病毒核心蛋白可降低微粒体甘油三酯转运蛋白（MTP）的活性，并可能导致丙型肝炎病毒感染患者出现脂肪变性。本研究旨在探讨MTP基因启动子区域功能性多态性（493G/T）对丙型肝炎病毒相关脂肪变性发展的影响。
方法
对86例慢性丙型肝炎患者进行研究，以评估体重指数、年龄、丙型肝炎病毒基因型和493G/T MTP多态性对脂肪变性的影响。
结果
39例患者（45.3%）出现脂肪变性。493G/T MTP多态性与脂肪变性的发展无关。
结论
功能性G/T MTP多态性似乎在慢性丙型肝炎脂肪变性的发展中不起任何作用。
