Abstract
Background and Aims:

Concordance between transient elastography (TE) and ultrasonography (US) in assessing liver fibrosis in patients with chronic hepatitis B (CHB) and concurrent nonalcoholic fatty liver disease (NAFLD) has been rarely studied. This study aimed to evaluate the individual and combined performances of TE and US in assessing liver fibrosis and cirrhosis.
Patients and Methods:

Consecutive CHB patients with NAFLD were prospectively enrolled. TE and US examinations were performed, with liver biopsy as a reference standard. Receiver operating characteristic (ROC) curves were obtained to evaluate the diagnostic performance. Differences between the areas under the ROC curves (AUCs) were compared using DeLong's test.
Results:

TE and US scores correlated significantly with the histological fibrosis staging scores. TE was significantly superior to US in the diagnosis of significant fibrosis (AUC, 0.84 vs 0.73; P=0.02), advanced fibrosis (AUC, 0.95 vs 0.76; P<0.001), and cirrhosis (AUC, 0.96 vs 0.71; P<0.001). Combining TE with US did not increase the accuracy of detecting significant fibrosis, advanced cirrhosis, or cirrhosis (P=0.62, P=0.69, and P=0.38, respectively) compared to TE alone. However, TE combined with US significantly increased the positive predictive value for significant fibrosis when compared to TE alone. The optimal cut-off values of TE for predicting advanced fibrosis and cirrhosis were 8.7 kPa and 10.9 kPa, with negative predictive values of 92.4% and 98.7%, respectively.
Conclusions:

TE is useful for predicting hepatic fibrosis and excluding cirrhosis in CHB patients with NAFLD. A combination of TE and US does not improve the accuracy in assessing liver fibrosis or cirrhosis.

抽象
背景和目的：

瞬态弹性成像（TE）和超声检查（US）在评估慢性乙型肝炎（CHB）和并发非酒精性脂肪性肝病（NAFLD）患者的肝纤维化方面的一致性很少被研究。本研究旨在评估TE和US在评估肝纤维化和肝硬化方面的个体和综合表现。
患者和方法：

前瞻性登记了连续患有NAFLD的CHB患者。进行TE和US检查，肝脏活组织检查作为参考标准。获得接收器操作特征（ROC）曲线以评估诊断性能。使用DeLong测试比较ROC曲线下面积（AUC）之间的差异。
结果：

TE和US评分与组织学纤维化分期评分显着相关。 TE在显着纤维化诊断中显着优于US（AUC，0.84 vs 0.73; P = 0.02），晚期纤维化（AUC，0.95 vs 0.76; P <0.001）和肝硬化（AUC，0.96 vs 0.71; P <0.001 ）。与单独的TE相比，将TE与US组合并未提高检测显着纤维化，晚期肝硬化或肝硬化（分别为P = 0.62，P = 0.69和P = 0.38）的准确性。然而，与单独的TE相比，TE与US联合显着增加了显着纤维化的阳性预测值。 TE预测晚期纤维化和肝硬化的最佳临界值分别为8.7 kPa和10.9 kPa，阴性预测值分别为92.4％和98.7％。
结论：

TE可用于预测患有NAFLD的CHB患者的肝纤维化和排除肝硬化。 TE和US的组合不能提高评估肝纤维化或肝硬化的准确性。
