摘要: 目的 探讨瞬时弹性成像(FibroScan)、磁共振质子密度脂肪分数(MRI-PDFF)和FAST评分识别高危非酒精性脂肪性肝炎(NASH)患者的应用价值。方法 2017年6月~2021年12月我院诊治的非酒精性脂肪肝病(NAFLD)患者107例,均接受肝活检和MRI-PDFF、FibroScan和血清学检查,计算FAST、FIB-4和APRI指数。采用单因素和多因素Logistic回归分析,应用受试者工作特征(ROC)曲线分析指标识别高危NASH患者的诊断效能。 结果 在107例NAFLD患者中,经肝组织病理学检查诊断高危非酒精性脂肪性肝炎(NASH)患者13例(12.1%),单纯性脂肪肝和非高危NASH患者94例(87.9%);高危NASH组LSM、FAST评分和APRI指数显著高于非高危组(P<0.05); 多因素Logistic回归分析显示,FibroScan检测的肝脏硬度 (LSM)是高危NASH患者的独立影响因素(P<0.05);ROC曲线分析显示LSM、FAST和APRI识别高危NASH患者有统计学意义(P<0.05),其曲线下面积 (AUC)分别为0.795、0.713和0.682,以LSM的诊断效能最优,其排除截断点诊断的敏感度和特异度分别为92.3%和54.3%,而纳入截断点诊断则为53.8%和90.4%。结论 对于FibroScan检测诊断的NAFLD患者,其LSM也同期升高高度提示NASH的存在,应进一步检查,以期早期干预。

Abstract: Objective The purpose of this study was to explore the diagnostic performance of FibroScan, magnetic resonance imaging proton density fat-fraction (MRI-PDFF) and FibroScan-AST(FAST)score in judging patients with high risk non-alcoholic steatohepatitis (NASH) from those with non-alcoholic fatty liver diseases (NAFLD). Mthods A total of 107 patients with NAFLD were encountered in our hospital between June 2017 and December 2021, and all patients underwent liver biopsies. FibroScan, MRI-PDFF and serological detection were completed and three non-invasive models of FAST, FIB-4 and APRI were calculated. Univariate and multivariate Logistic regression analysis was used to screen out factors impacting high-risk NASH. The diagnostic performance of relevant parameters and three non-invasive models to identify high risk NASH was analyzed by ROC curve. Result Of 107 patients with NAFLD, the histo-pathological examination showed high risk NASH in 13 cases (12.1%), and simple alcoholic fatty liver and non-high risk NASH in 94 cases (87.9%); liver stiffness measurement (LSM) by Fibroscan, FAST score and aspartate aminotransferase/platelets (APRI) in patients with high risk NASH were significantly higher than in those with non-high risk NASH (P<0.05);multivariate Logistic regression analysis showed that only the LSM was the independent risk factor impacting high risk NASH(P<0.05);ROC analysis demonstrated that the LSM, FAST and APRI could identify high risk NASH(P<0.05), with AUCs of 0.795, 0.713 and 0.682, and the LSM got the optimal diagnostic efficacy, with sensitivity (Se) and specificity (Sp) of 92.3%and 54.3% based on exclusion cut-off-value, and with Se and Sp of 53.8%and 90.4% based on inclusion cut-off-value. Conclusion The simultaneous increased LSM in patients with NAFLD hints existence of NASH, which might help clinicians make appropriate measures to tackle it.
