Effect of hepatogenous jaundice on liver stiffness measurement in patients with chronic hepatitis B / 中华超声影像学杂志

ABSTRACT

To evaluate the impact of intrahepatic cholestasis on liver stiffness measurement ( LSM ) of two‐dimensional shear wave elastography ( 2D‐SWE ) in patients with chronic hepatitis B . Methods Between June 2011 and December 2016 , total of 1 188 patients with chronic hepatitis B infection were enrolled to collect clinical ,2D‐SWE ,biochemical variables and histological ( M ET AVIR scoring system ) datas . LSM was compared between normal total bilirubin group ( TB ＜ 23 .9 μmol/L ) versus abnormal TB group( ≥23 .9 μmol/L ) . Correlation of TB with LSM s was assessed . Results Nine hundred and seventy‐three patients with effective LSM in the study were analyzed . Within the same fibrosis stage ( F1‐F4) ,LSM showed significantly higher value in abnormal TB group than those of normal TB group ( r＝0 .328 ,0 .247 ,0 .495 ,0 .435 ,all P ＜ 0 .001 ) . Increased LSM for abnormal TB group was generally found within different subset of patients [ fibrosis stage ≤ F2 ,AL T ≥ 2 × upper limit of normal ( ULN ) ;fibrosis stage≤ F2 ,M ET AVIR activity grade ≤ A1 or ≥ A2 ] ,with r ＝ 0 .266 ,0 .210 ,0 .243 ( all P ＜0 .001) ,respectively .Increased LSM for abnormal TB group was also found within different subset of patients [ fibrosis stage≥F3 ,AL T＜2× ULN ,≥2×ULN ; fibrosis stage≥F3 ,M ET AVIR activity grade≥A2 ,with r ＝ 0 .671 ,0 .200 ,0 .468 ( all P ＜ 0 .05 ) ] . Conclusions Hepatogenous jaundice induced to intrahepatic cholestasis shows slight positive correlation with LSM s in patients with chronic hepatitis B .
