Abstract
Background/Aims:

Nonalcoholic fatty liver disease (NAFLD) is becoming a worldwide epidemic, and is frequently found in patients with chronic hepatitis B (CHB). We investigated the impact of histologically proven hepatic steatosis on the risk for hepatocellular carcinoma (HCC) in CHB patients without excessive alcohol intake.
Methods:

Consecutive CHB patients who underwent liver biopsy from January 2007 to December 2015 were included. The association between hepatic steatosis (≥ 5%) and subsequent HCC risk was analyzed. Inverse probability weighting (IPW) using the propensity score was applied to adjust for differences in patient characteristics, including metabolic factors.
Results:

Fatty liver was histologically proven in 70 patients (21.8%) among a total of 321 patients. During the median (interquartile range) follow-up of 5.3 (2.9-8.3) years, 17 of 321 patients (5.3%) developed HCC: 8 of 70 patients (11.4%) with fatty liver and 9 of 251 patients (3.6%) without fatty liver. The five-year cumulative incidences of HCC among patients without and with fatty liver were 1.9% and 8.2%, respectively (P=0.004). Coexisting fatty liver was associated with a higher risk for HCC (adjusted hazards ratio [HR], 3.005; 95% confidence interval [CI], 1.122-8.051; P=0.03). After balancing with IPW, HCC incidences were not significantly different between the groups (P=0.19), and the association between fatty liver and HCC was not significant (adjusted HR, 1.709; 95% CI, 0.404-7.228; P=0.47).
Conclusions:

Superimposed NAFLD was associated with a higher HCC risk in CHB patients. However, the association between steatosis per se and HCC risk was not evident after adjustment for metabolic factors.

抽象
背景/目的:

非酒精性脂肪性肝病(NAFLD)正在成为世界范围的流行病,并且经常在慢性乙型肝炎(CHB)患者中发现。我们研究了组织学证实的肝脂肪变性对CHB患者肝细胞癌(HCC)风险的影响,而没有过量饮酒。
方法:

包括2007年1月至2015年12月接受肝活检的连续CHB患者。分析肝脏脂肪变性(≥5%)与随后的HCC风险之间的关系。使用倾向得分的反向概率加权(IPW)用于调整患者特征的差异,包括代谢因素。
结果:

在总共321名患者中,70名患者(21.8%)组织学证实了脂肪肝。在5.3(2.9-8.3)年的中位数(四分位数间)随访期间,321名患者中有17名(5.3%)患有HCC:70名患者中有8名(11.4%)患有脂肪肝,11名患者中有9名患者(3.6%)没有脂肪肝。没有和有脂肪肝的患者中HCC的五年累积发生率分别为1.9%和8.2%(P = 0.004)。共存的脂肪肝与HCC的高风险相关(调整后的危险比[HR],3.005; 95%置信区间[CI],1.122-8.051; P = 0.03)。在与IPW平衡后,HCC发生率在各组之间没有显着差异(P = 0.19),并且脂肪肝和HCC之间的关联不显着(调整的HR,1.709; 95%CI,0.404-7.228; P = 0.47)。
结论:

叠加的NAFLD与CHB患者的较高HCC风险相关。然而,在调整代谢因素后,脂肪变性本身与HCC风险之间的关联并不明显。
