Abstract:
Objective To explore the diagnostic value of Young's modulus obtained by real-time shear wave elastography (SWE) for liver fibrosis in autoimmune hepatitis (AIH) patients. Methods A total of 75 AIH patients in the First Affiliated Hospital of Zhengzhou University from January 2013 to April 2022 were retrospectively enrolled. Scheuer scoring system was used to evaluate degrees of liver fibrosis (S0-S4). By using pathological examination of liver tissues as the golden standard, the receiver operating characteristic curve (ROC) was plotted and the area under the curve (AUC) was used to evaluate the diagnostic value of SWE for the significant fibrosis (≥S2), advanced liver fibrosis (≥S3), and liver cirrhosis (S4), respectively. Independent sample t test was used for comparison of continuous data with normal distribution between the two groups. The Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups and Bonferroni method was used for further comparison between two groups. The Spearman correlation coefficient was used for correlation analysis. The logistic regression analysis was used to predict the impact factors in diagnosis accuracy. Results The Young's modulus measured by SWE was statistically significant different among various fibrosis groups ( H =35.186, P < 0.001) although there was no statistical significance in patients' age and platelet, alanine aminotransferase, aspartate aminotransferase, total bilirubin, alkaline phosphatase, and glutamyl transpeptidase levels (all P > 0.05). The Young's modulus measurement was positively correlated with liver fibrosis ( r =0.675, P < 0.05). The AUCs of SWE in the diagnosis of≥S2, ≥S3, and S4 were 0.839, 0.820 and 0.898, respectively and the corresponding optimum cut-off values were 9.2, 10.9, and 14.4 kPa, respectively. The overall concordance rate of the liver Young' s modulus measurements vs . fibrosis stages was 57.33%. Moreover, the alkaline phosphatase level was an independent predictor for diagnostic accuracy of SWE for stage 0-1 fibrosis ( OR =1.009, 95% CI : 1.001-1.018, P =0.029). Conclusion The SWE possessed a diagnosis value for the significant fibrosis (≥S2), advanced liver fibrosis (≥S3) and liver cirrhosis (S4), although there was a low overall concordance rate in the liver Young's modulus measurements obtained using SWE vs. fibrosis stages.
