title: Real-time shear wave elastrography and APRI index for evaluating autoimmune hepatitis fibrosis.
abstract: The objective of this study was to investigate the significance of real-time supersonic shear imaging (SSI) and serum biochemical index in evaluating the degree of autoimmune hepatitis fibrosis. Retrospective analysis was carried out to study 291 cases of patients with autoimmune hepatitis, and discuss the value of SSI application, APRI index and bilirubin on autoimmune hepatitis. The area under the receiver operating characteristic curve (AUROC) was taken for statistical analysis to determine its diagnostic accuracy. In the high degree of hepatic fibrosis, the hepatic SSI measured value of autoimmune hepatitis positively correlated to ALT, AST, APRI ratio, AST and AST/ALT. The SSI measured value significantly and positively correlated to the degree of hepatic fibrosis (r=0.598, p=0 less than 0.01). In chronic hepatic fibrosis, the elasticity values of AIH, PBC, AIH-PBC overlap syndrome (OS) were in a rising trend, and the difference in the elasticity value of each fibrosis stage was statistically significant (P less than 0.01). Hepatic SSI measured value was employed to respectively detect the AUROC of S3 stage and S4 stage for AIH, PBC, and AIR-PBC OS groups, which resulted as being higher than the APRI index detected in S3 stage and S4 stage. SSI measured index had better diagnostic significance than APRI index on hepatic fibrosis for AIH, PBC and AIH-PBC OS groups.
