Abstract
Background:

Sodium taurocholate cotransporting polypeptide (NTCP, SLC10A1) was recently identified as a hepatocyte receptor for infection of Hepatitis B virus (HBV). The natural S267F variant in NTCP causes a loss of HBV receptor function of NTCP.
Objective:

We assessed the association of S267F with HBV resistance, HBV infection clearance, and HBV-related cirrhosis and HCC.
Methods:

We tested the effects of S267F in 1117 Han Chinese patients with various HBV infection outcomes using multivariate logistic regression analysis.
Results:

The frequency of S267F (T allele) was higher in HBV-resistance healthy controls (n = 179, 4.0%) compared to HBV-infected patients (n= 648, 1.5%), with odds ratio [OR] 0.32 [95% confidence interval [CI] 0.15-0.68], p = 0.003 (dominant model). The 267F variant genotypes were also associated with reduced risk for cirrhosis (n=192, 0.5%) and HCC (n=258, 1.0% compared to those with chronic HBV infection (n=202, 3.0%), with OR 0.15 [0.03-0.70] and OR 0.21 [ 0.062-0.72], respectively. There was no association of the S267F variant with spontaneous HBV clearance.
Conclusion:

Carriage of the S267F variant for the HBV cell-entry receptor NTCP was associated with increased resistance to HBV infection and decreased risk of development of cirrhosis and liver cancer among those with chronic HBV infection.

抽象
背景:

牛磺胆酸钠共转运多肽(NTCP,SLC10A1)最近被鉴定为乙型肝炎病毒(HBV)感染的肝细胞受体。 NTCP中的天然S267F变体导致NTCP的HBV受体功能丧失。
目的:

我们评估了S267F与HBV抗性,HBV感染清除率以及HBV相关性肝硬化和HCC的关联性。
方法:

我们使用多因素logistic回归分析检测了1117名具有各种HBV感染结果的汉族患者中S267F的作用。
结果:

与HBV感染患者(n = 648,1.5%)相比,HBV耐药健康对照(n = 179,4.0%)中S267F(T等位基因)的频率更高,优势比[OR]为0.32 [95%区间[CI] 0.15-0.68],p = 0.003(显性模型)。与慢性HBV感染者(n = 202,3.0%)相比,267F变异基因型还与肝硬化风险降低(n = 192,0.5%)和HCC相关(n = 258,1.0%),OR 0.15 [0.03 -0.70]和OR 0.21 [0.062-0.72],S267F变异与自发性HBV清除无关。
结论:

携带乙型肝炎病毒进入受体NTCP的S267F变体与慢性乙型肝炎病毒感染者的HBV感染抵抗力增加和肝硬化和肝癌发生风险降低相关。
