摘要: 目的 比较研究弹性成像与二维超声剪切波弹性成像(2D-SWE)评估代谢功能障碍相关脂肪性肝病(MAFLD)患者肝纤维化的效能。方法 2022年3月~2024年10月我院诊治的110例MAFLD患者,均接受肝活检,使用Fibrotouch行肝脏硬度检测(LSM)和受控衰减参数(CAP),使用2D-SWE检测杨氏模量值。应用受试者工作特征(ROC)曲线评估诊断效能。结果 在110例MAFLD患者中,肝组织病理学检查诊断代谢相关性单纯性脂肪肝(MRSFL)62例和代谢相关性脂肪性肝炎(MASH)48例,其中F2期肝纤维化30例,F3期15例,F4期3例;MASH组血清总胆固醇、甘油三酯、低密度脂蛋白和丙氨酸氨基转移酶水平均显著高于,而血清高密度脂蛋白水平显著低于MRSFL组,差异均具有统计学意义(P<0.05); MASH组CAP、LSM和杨氏模量值分别为(315.2±20.6)dB/m、(12.0±2.3)kPa和(10.1±2.1)kPa,均显著高于MRSFL组【分别为(267.8±8.4)dB/m、(5.9±1.4)kPa和(4.9±1.4)kPa,P<0.05】;ROC曲线分析结果表明,LSM诊断显著性肝纤维化的AUC为0.899(95%CI:0.831~0.987),其敏感性为0.888,特异性为0.826,而杨氏模量值也具有较好的诊断效能(AUC为0.885,95%CI:0.822~0.949,敏感性为0.796,特异性为0.806)。结论 使用LSM或2D-SWE检测诊断MAFLD患者显著性肝纤维化均具有很大的临床应用价值。

Abstract: Objective The aim of this study was to compare diagnostic efficacy of transient elastography (TE) to two-dimensional shear wave elastography (2D-SWE) in assessing significant liver fibrosis (SLF) in patients with metabolic dysfunction-associated fatty liver disease (MAFLD). Methods A total of 110 patients with MAFLD were encountered in our hospital between March 2022 and October 2024, and all underwent liver biopsies. TE was performed to obtain liver stiffness measurement (LSM) and controlled attenuation parameter (CAP), and Young's modulus was obtained by 2D-SWE. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the diagnostic performance. Results Of the 110 patients with MAFLD, liver histo-pathological examination proven metabolic related simple fatty liver (MRSFL) in 62 cases and metabolic dysfunction-associated steatohepatitis(MASH) in 48 cases, including F2 stage of liver fibrosis in 30 cases, F3 in 15 cases and F4 in 3 cases; serum total cholesterol, triglyceride, low-density lipoprotein and alanine aminotransferase levels in patients with MASH were significantly higher, while serum high-density lipoprotein level was significantly lower than in patients with MRSFL(P<0.05); CAP, LSM and Young's modulus in patients with MASH were (315.2±20.6)dB/m, (12.0±2.3)kPa and (10.1±2.1)kPa, all much higher than [(267.8±8.4)dB/m,(5.9±1.4)kPa and (4.9±1.4)kPa, respectively, P<0.05] in those with MRSFL; ROC analysis showed that the AUC was 0.899(95%CI: 0.831-0.987), with sensitivity (Se) of 0.888 and specificity (Sp) of 0.826, when LSM was applied to predict SLF, and the AUC was 0.885 (95%CI:0.822-0.949), with Se of 0.796 and Sp of 0.806, when Young's modulus was applied. Conclusion Both LSM and 2D-SWE could help predict SLF non-invasively in patients with MAFLD, which should be a widespread tool for clinical application.
